Objective: Several inflammatory indices have been used to assess the prognosis of ovarian cancer, with variable results. This review assessed whether the systemic immune inflammation index (SII) can predict outcomes in patients with ovarian cancer. Methods: Embase, PubMed, CENTRAL, Web of Science, and Scopus databases were searched by the two reviewers from inception to 15th October 2024 for studies assessing the relationship between SII and overall survival (OS) or disease-free survival (DFS). Results: Ten studies with eleven cohorts were included. Pooled analysis showed that higher SII was a significant predictor of poor OS (HR: 2.35 95% CI: 1.56, 3.55 I2 = 88%) and worse DFS (HR: 2.51 95% CI: 1.71, 3.67 I2 = 80%) after ovarian cancer. Sensitivity analysis failed to change the significance of the results. No publication bias was noted. Most results remained significant on subgroup analyses based on location, sample size, FIGO stage, treatment, adjusted outcomes, cut-off of SII, method of determining cut-off, and quality score. Conclusions: SII can be a potential predictor of OS and DFS after ovarian cancer. Further studies are required to improve the evidence. [ABSTRACT FROM AUTHOR]

CYTOKINE release syndrome , *CHIMERIC antigen receptors , *PROGNOSIS , *BLOOD-brain barrier , *ENCEPHALITIS - Abstract
Chimeric antigen receptor (CAR) T-cell therapy has emerged as a promising treatment for hematologic malignancies, offering significant therapeutic benefits. However, this therapy is also associated with adverse effects such as cytokine release syndrome and Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS), which can lead to severe neurological symptoms. The pathophysiology of ICANS remains unclear but is believed to involve immune-mediated inflammation in the brain. This study investigates the potential of S100, a protein marker associated with blood-brain barrier integrity, as an early indicator of ICANS.Introduction: We retrospectively analyzed daily blood samples for S100 levels in patients undergoing CAR T-cell therapy, correlating these levels with the onset and severity of ICANS.Methods: The results show that S100 levels significantly increased in patients who developed ICANS, with a positive correlation between the duration of elevation and the severity of the neurological symptoms.Results: These findings suggest that S100 may serve as a useful biomarker for early detection of ICANS and could potentially guide therapeutic interventions. However, further studies are needed to fully understand its prognostic value in this context. [ABSTRACT FROM AUTHOR]Conclusion: - Published

AbstractBackgroundMethodsResultsConclusionsMetabolic dysfunction-associated fatty liver disease (MAFLD) can trigger inflammation, hepatocellular damage, cirrhosis, and hepatocellular carcinoma. There is a need for non-invasive, cost-effective diagnostic markers for MAFLD, as current methods like liver biopsy are invasive. This study investigates the potential of the systemic immune inflammation index (SII) as a useful tool in diagnosis of MAFLD.A cohort of 806 individuals, including 426 with MAFLD and 380 controls, was analyzed. SII values, along with various biochemical and inflammatory markers, were compared between groups.The MAFLD group exhibited significantly higher SII values, which correlated with key markers of liver inflammation and function. Median SII levels of the MAFLD patients (581 (45–4553)) were significantly higher than that of the control group (423 (112–2595)) (
p <0.001). SII showed moderate sensitivity (72%) and specificity (56%) in detecting MAFLD. Logistic regression analysis identified SII as an independent risk factor for MAFLD, with a unit increase in SII increasing the risk by 1.21 times.These findings suggest that SII could serve as a useful, noninvasive marker for diagnosing and monitoring MAFLD, warranting further longitudinal studies to explore its role in disease progression and treatment response.

Background: De novo neuroendocrine prostate cancer (NEPC) is a rare subtype of prostate cancer (PCa) and few markers are available for screening and monitoring. Potential circulating or fluid markers might facilitate early diagnosis thus improving prognosis of NEPC, especially for de novo NEPC. Case presentation: A man of 71-year was presented with elevated level of serum carcinoembryonic antigen (CEA) (1296.5 ng/ml) and normal PSA (0.47ng/ml). Gastrointestinal endoscopy showed no signs of gastric or colorectal cancer. Fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) and prostate-specific membrane antigen PET-CT (PSMA PET-CT) indicated prostate cancer with metastases including pelvic lymph nodes, bone as well as lung metastases. Biopsy of prostate revealed mixed carcinoma including small cell neuroendocrine carcinoma (SCNEC) and adenocarcinoma (Gleason score of 4 + 5). Immunohistochemistry (IHC) staining and next generation sequencing demonstrated a strong expression of chromogranin A (CgA), synaptophysin (SYN) and CEA, and a germline mutation in BRCA2, respectively. After a prostatic massage, an increased level of CEA (137 ng/ml vs 5 ng/ml) was detected in urine. Olaparib, a Poly ADP-ribose polymerase inhibitor (PARPi), combined with androgen deprivation therapy (ADT) were administrated. FDG PET-CT indicated tumor regression in both quantity and size three months later, and CEA levels of serum and urine decreased to 23 ng/ml and 2.4 ng/ml 4 months later, respectively. Conclusion: This is the first report of a de novo NEPC presented with an elevated level of CEA, in which CEA was also detected in urine specimen post a prostatic massage. After a combination treatment of ADT for 3 months, levels of CEA in both serum and urine decreased sharply when tumor regressed radiologically. CEA might be a marker of screening and monitoring of NEPC. [ABSTRACT FROM AUTHOR]

Background and Objectives: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy characterized by a dense desmoplastic stroma with a poor prognosis. The aim of this study was to investigate whether resolvin (Rv) D1 could be used as a potential serum biomarker to discriminate between PDAC and acute pancreatitis (AP). Materials and Methods: In total, 67 patients were enrolled in the present study, including 21 patients with resectable PDAC, 23 patients with metastatic PDAC, 23 patients with AP, and a control group of 21 healthy individuals. RvD1 levels of PDAC patients were also analyzed through ELISA at the 6th postoperative month. Results: The mean RvD1 was 1169.24 ± 285.99 in the control group, 885.04 ± 134.25 in the AP group, 728.57 ± 140.1 in the PDAC group, and 670.09 ± 105.6 in the metastatic pancreatic cancer (PC) group. RvD1 was significantly lower in PDAC and metastatic PC groups compared to controls and patients with AP, while it was significantly lower in patients with AP compared to the control groups. Postoperative RvD1 levels of patients with PDAC were significantly higher than preoperative levels (728.57 ± 140.1 vs. 885.43 ± 275.57). In the ROC analysis, when the cut-off value for serum RvD1 level was 825 ng/L, it was found to predict PDAC from metastatic PC with 84.1% sensitivity and 81.8% specificity. Conclusions: Serum RvD1 is a new biomarker for the detection of PDAC. Serum RvD1 may provide an important diagnostic contribution in clinical practice to predict PDAC. Serum RvD1 levels were found to be predictive with high sensitivity and specificity in differentiating PDAC from metastatic PC. However, it was concluded that serum RvD1 levels cannot be used as a detection marker to differentiate PDAC from AP. RvD1 could be a representative agent of a new class of drugs to be proposed for innovative treatment of AP and PDAC. Our future study will investigate whether RvD1 can be a marker to differentiate from chronic pancreatitis. [ABSTRACT FROM AUTHOR]

Fish disease outbreaks caused by bacterial burdens are responsible for decreasing productivity in aquaculture. Unraveling the molecular mechanisms activated in the gonads after infections is pivotal for enhancing husbandry techniques in fish farms, ensuring disease management, and selecting the most resilience phenotype. The present study, with an important commercial species the European sea bass (Dicentrarchus labrax), an important commercial species in Europe, examined changes in the miRNome and transcriptome 48 h after an intraperitoneal infection with Vibrio anguillarum. The findings indicate that following infection, testes exhibited more pronounced alterations in both the miRNome and transcriptome. Specifically, males showed approximately 26% more differentially expressed genes in testicular genes compared to females (2,624 vs. 101 DEGs). Additionally, four miRNAs (miR-183-5p, miR-191-3p, miR-451-5p, and miR-724-5p) were significantly expressed post-infection in males, while none were identified in females. Interestingly, upon deep analysis of sexual dimorphic gene modules, a larger number of miRNAs were identified in infected females targeting genes related to the immune system compared to infected males. These results suggest that fish ovaries demonstrate greater resilience in response to infections by suppressing genes related to the immune system through a post-transcriptional mechanism performed by miRNAs. In contrast, testes activate genes related to the immune system and repress genes related to cellular processes to cope with the infection. In particular, the crosstalk between the miRNome and transcriptome in infected males revealed a pivotal gene, namely, insulin-like growth factor binding protein (igfbp), acting as a gene network hub in which miR-192-3p was connected. The current study elucidated the need to comprehend the basic immune regulatory responses associated with miRNAs and gene regulation networks that depend on fish sex. The data reveal the importance of considering sex as a factor in interpreting the immune system in fish to generate efficient protocols to prevent outbreaks in fish farms. Plain English summary: This study investigates how European sea bass (Dicentrarchus labrax) respond to infections caused by the bacteria Vibrio anguillarum, with a focus on understanding the molecular mechanisms in the gonads. Fish disease outbreaks are a major issue in aquaculture, and knowing how fish resist infections can improve disease management. Researchers analyzed changes in the miRNome (microRNAs) and transcriptome in male and female European sea bass 48 h after infection. The results showed that males had more significant changes in gene expression compared to females, with 2,624 differentially expressed genes in testes vs. 101 in ovaries. Four specific miRNAs were active in males post-infection, but none were found in females. However, females exhibited a higher number of miRNAs targeting immune-related genes, suggesting that ovaries may suppress immune responses better than testes. Males, on the other hand, activated immune-related genes while suppressing cellular processes to fight the infection. A key gene, insulin-like growth factor binding protein (igfbp), was identified as important in male immune response, connected to miR-192-3p. This study highlights the importance of considering fish sex as a relevant factor when studying immune responses, as it could help develop better disease prevention strategies in aquaculture. Highlights: Testes showed more molecular changes at the microRNome and transcriptome levels in response to infection than ovaries. In testes of infected fish, miR-183-5p and miR-191-3p were upregulated while miR-451-5p and miR-724-5p were downregulated. Larger number of target genes were inhibited in females which were mostly related to the immune system. Importance of considering sexual dimorphism in immune responses was highlighted.

Introduction: Primary cilia play an important role in the development of cancer by regulating signaling pathways. Several studies have demonstrated that women with BRCA mutations have, on average, 50% fewer ciliated cells compared with general women. However, the role of tubal cilia loss in the development of epithelial ovarian cancer (EOC) remains unclear. Few specific studies have been found in linking HYDIN , a ciliary defect associated gene that encodes HYDIN axonemal central pair apparatus protein, which is involved in the transduction of Hedgehog (Hh) signal and is considered a cancer associated antigen, to ovarian cancer. Therefore, our study aimed to investigate the correlation between HYDIN gene mutations and tubal cilia loss in EOC. Methods: A whole exome sequencing (WES), immunohistochemistry (IHC), western blot, and reverse transcription quantitative (RT q) PCR were performed in 80 patients with EOC and 50 cases of non ovarian cancer to detect the mutations and expression of tubal ciliary marker, ciliary morphology, and abnormal rate. Results: We found that the incidence of tubal cilia loss was higher in EOC group with decreased expression of HYDIN compared with the control group (P<0.05). Discussion: This study suggests that tubal ciliary loss is evident in epithelial fallopian tube carcinoma, and ciliary cells may be involved in the occurrence and development of EOC, and cilia-related gene HYDIN is expected to be a tumor marker for epithelial ovarian cancer.

Studies on the genetic basis of bicuspid aortic valve (BAV), characterized by a configuration of the aortic valve with two leaflets instead of three, are insufficient. This study aimed to elucidate the possible relationship between BAV and TGF-β1 gene expression levels. Forty-eight pediatric patients diagnosed with isolated BAV and 50 healthy children with innocent heart murmurs were included in the study. A comprehensive transthoracic echocardiographic examination was performed using the Vivid S5 Pro Ultrasound for all children. TGF-β1 gene expression levels were detected by RT-PCR method. The mean age of the patients was 8.54 ± 5.3 years, and the mean age of the children in the control group was 7.07 ± 5.34 years. It was noted that TGF-β1 gene expression level increased 2.91 times in the patient group compared to the control group (p = 0.03). TGF-β1 gene expression levels of patients with BAV decreased with age. This is the first study to show TGF-β1 gene expression levels in children with BAV. According to the results of our study, TGF-β1 gene expression levels in children with BAV decrease with age. Further studies are needed in all age groups to use TGF-β1 as a prognostic marker in patients with BAV. [ABSTRACT FROM AUTHOR]

Objective: In the present study, we aimed to compare serum CK‐MM levels in patients with and without adenomyosis and to investigate whether CK‐MM level can be a non‐invasive marker for myometrial damage due to adenomyosis. Materials and Methods: Our study was a prospective case‐control study in a tertiary center and consisted of 40 patients with a clinical/ultrasonographic diagnosis of adenomyosis and 40 patients without a clinical/ultrasonographic diagnosis of adenomyosis as the control group based on recently published morphological uterus sonographic assessment (MUSA) criteria. Individuals of similar age who signed a voluntary consent form were included in our study. Demographic, clinical, and laboratory findings of the patients in both groups were recorded. Blood serum samples were used for the determination of serum CK‐MM levels of the participants in our study. The samples were analyzed by using the human CK‐MM enzyme‐linked immunosorbent assay (ELISA) kit. Results: In our study, the mean serum CK‐MM level was 16.2 ± 21.7 (ng/dL) in patients with adenomyosis and 2.6 ± 2.2 (ng/dL) in patients without adenomyosis. Serum CK‐MM level was statistically significantly higher in the patient group with adenomyosis than in the control group (p < 0.001). The CK‐MM threshold value of 3.43 ng/mL, with a sensitivity of 82.5% and specificity of 85%, has been found to be a valuable distinguishing level in patients with and without adenomyosis. Conclusion: In this study, we demonstrated that serum CK‐MM can be used as a non‐invasive diagnostic method in patients with adenomyosis. As the number of studies around this subject in the literature is insufficient, larger studies are needed to use CK‐MM as a diagnostic marker in adenomyosis. Synopsis: CK‐MM could be a predictive marker in the non‐invasive diagnosis of adenomyosis in the future. [ABSTRACT FROM AUTHOR]

Background/Objectives: Salivary gland carcinomas encompass a broad group of malignant lesions characterized by varied prognoses. Stem cells have been associated with the potential for self-renewal and differentiation to various subpopulations, resulting in histopathological variability and diverse biological behavior, features that characterize salivary gland carcinomas. This study aims to provide a thorough systematic review of immunohistochemical studies regarding the expression and prognostic significance of stem cell markers between different malignant salivary gland tumors (MSGTs). Methods: The English literature was searched via the databases MEDLINE/PubMed, EMBASE via OVID, Web of Science, Scopus, and CINHAL via EBSCO. The Joanna Briggs Institute Critical Appraisal Tool was used for risk of bias (RoB) assessment. Meta-analysis was conducted for markers evaluated in the same pair of diseases in at least two studies. Results: Fifty-four studies reported the expression of stem cell markers, e.g., c-KIT, CD44, CD133, CD24, ALDH1, BMI1, SOX2, OCT4, and NANOG, in various MSGTs. Low, moderate, and high RoB was observed in twenty-five, eleven, and eighteen studies, respectively. Meta-analysis revealed an outstanding discriminative ability of c-KIT for adenoid cystic carcinoma (AdCC) over polymorphous adenocarcinoma [P(LG)A] but did not confirm the prognostic significance of stem cell markers in MSGTs. Conclusions: This study indicated a possible link between stem cells and the histopathological heterogeneity and diverse biological behavior that characterize the MSGTs. c-KIT might be of diagnostic value in discriminating between AdCC and P(LG)A.

- Abstract
Cashew is a tree of great commercial importance. The demand for cashew nuts and by-products is increasing. An increase in cashew production is possible through genetic enhancement by effective utilization of germplasm. However, the utility of cashew germplasm in the breeding programme is limited by the lack of reliable data on germplasm characterizations. In this research study, we identified 11 germplasm accessions with unique traits through a genebank survey and evaluated them for morphological and biochemical characteristics and genetic diversity. Morphological characterization revealed significant variations, and high variability was observed for qualitative characteristics like nut stylar region width, cashew apple shape, and color. The morphometric traits such as the cashew nut, kernel, and cashew apple dimensions and weights also showed great variability. The correlation analysis showed that the nut weight had strong correlations with traits like kernel weight (r = 0.95) and shell thickness (r = 0.95). Biochemical analysis for cashew nut shell liquid (CNSL), kernel oil, and cashew apple juice content and TSS showed significant variations in the tested accessions. Correlations were observed between CNSL content and shell thickness. Further, genetic diversity analysis of accessions using nine genic simple sequence repeats (SSRs) detected a sum of 64 alleles, and the accessions were divided into three major clusters by the neighbor-joining method. This study confirms that the identified accessions are genetically diverse and are promising candidates for varietal development. The correlations between characters indicated the scope for simultaneous selections for the strongly correlated characters with economic importance. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: Resolvin D1 (RvD1) inhibits inflammation, reduces oxidative stress, and forecasts the risk of cardiovascular events, but relevant evidence in hemodialysis patients is lacking. This study intended to investigate the predictive value of RvD1 for major adverse cardiovascular events (MACE) risk in hemodialysis patients. Methods: Totally, 252 patients who underwent hemodialysis were included. Serum RvD1 was measured by enzyme-linked immunosorbent assay. Patients were followed up with a median of 12.1 months. MACE was recorded during the follow-up period. Results: RvD1 was inversely correlated with diabetes history (P = 0.002), cardiac troponin T (TnT) (P = 0.029), and high sensitivity C-reactive protein (hsCRP) (P < 0.001) in hemodialysis patients. 25 hemodialysis patients experienced MACE. RvD1 was reduced in hemodialysis patients with MACE versus those without MACE (P = 0.004). RvD1 exhibited a certain value in forecasting MACE risk, with an area under curve (AUC) of 0.675 [95% confidence interval CI: 0.565–0.786]. Increased RvD1 cut by median (P = 0.043) and cut by quartile (P = 0.042) were related to decreased accumulating MACE in hemodialysis patients. Moreover, RvD1 independently predicted declined MACE risk [odds ratio (OR) = 0.644, P = 0.045], but age (OR = 1.048, P = 0.039) and TnT (OR = 1.006, P = 0.005) independently predicted ascended MACE risk in hemodialysis patients. The combination of these independent factors displayed a good value for estimating MACE risk in hemodialysis patients with an AUC of 0.744 (95% CI: 0.640–0.849). Conclusion: Serum RvD1 is inversely correlated with diabetes history, TnT, and hsCRP in hemodialysis patients. More importantly, it could serve as a potential marker to predict MACE risk in these patients. [ABSTRACT FROM AUTHOR]

Abstract This study aimed to evaluate the diagnostic accuracy of ultrasonography in assessing the response of clipped axillary lymph nodes to neoadjuvant chemotherapy. Between February 2022 and September 2023, 43 patients who underwent axillary lymph node marking for targeted axillary dissection were retrospectively analyzed. Ultrasonography parameters such as the number, size, shape, cortical thickness, hilum status, and treatment response of the clipped lymph node were assessed. Post-surgery pathology results served as the gold standard. Ultrasonography revealed 70% complete and 30% partial response, while pathology results showed 51% complete response, 9% micro-metastases, and 40% macro-metastases. The diagnostic accuracy of ultrasonography was 81.4%, with 61.9% sensitivity and 100% specificity. A significant correlation was found between clipped node response in ultrasound and pathology. Additionally, a notable association was observed between clipped node response on ultrasonography, molecular subtype of the breast mass, and the mass’s response to NAC. Assessing the treatment response of clipped lymph nodes with preoperative ultrasound, followed by surgical excision using needle wire localization, can be a viable alternative to axillary dissection, offering low false-negative rates.

- Abstract
The degradation of toxic polycyclic aromatic nitrogen heterocycles (PANHs) and their alkylated counterparts (APANHs) after an oil spill has not been extensively investigated. A lack of available standards and the available standards' high cost have inhibited progress in understanding their stability in the environment. In the current study, the knowledge gap was reduced by implementing a gas chromatography quadrupole time-of-flight (GC-QToF) method for a cost-effective and time-efficient determination of multiple polycyclic aromatic compounds, including related PANHs and APANHs. Some of the issues related to the availability and high cost of PANH standards were tackled using an adaptation of a high-resolution method that employs polycyclic aromatic hydrocarbons (PAHs) as substitute analog standards. To determine the stability of PANHs and APANHs during weathering, crude oils were subjected to a microcosm experiment, simulating conditions in an aquatic environment found off the West Coast of Canada. Over the course of this study, PAHs, APAHs, PANHs, and APANHs, were observed to follow similar weathering trends. The number of aromatic rings and nitrogen substitution were found to significantly impact the stability of the targeted compounds. This investigation resulted in the identification of twenty, previously un-explored PANH/APANH compounds as potential markers to enhance accuracy and confidence in oil spill forensics, in particular C0–C4 benzo(a)carbazoles, C3–C4 quinoline/isoquinolines, and C0–C4 benzo(c)acridine.

The article compares the semantics of the lexical group “the names of women by marital status” in the Belarusian literary language and in the northeastern dialect, the distribution area of which is the Vitebsk region and part of the Mogilev region. Of the 24 names extracted from the general language and regional dictionaries, the overwhelming majority (two-thirds, i.e. 66.66%) are literary words. This is natural, since the literary language as the core of the national language has a more extensive vocabulary. The names of women were divided according to marital status, i.e. in relation to marriage, into four subgroups: premarital, marital, postmarital, and extramarital. The words for women in marriage have the same number in the literary language and in the dialect. Literary names of women of illegitimate status have a significant numerical advantage – 4 to 1 dialect word. Although there are fewer dialect names, they differ, firstly, in greater expressiveness and figurativeness, and, secondly, in a variety of word formation means – suffixes. The analysis also showed that the evaluative connotations of units in this lexico-semantic group (LSG) are influenced by sociocultural gender stereotypes. Words denoting women in premarital and marital status have a positive connotation, the names of women in extramarital status have a negative connotation, and the names of divorced women have a negative connotation as well.

Oral cancer became a very common condition. WHO estimates that there are 4 cases of lip and oral cavity cancer for every 100,000 people worldwide. The early diagnosis of cancers is currently a top focus in the health sector. Recent systematic reviews and meta-analyses have identified promising biomarkers for early detection in several original research investigations. However, it is still unclear the quality of these evidence and which biomarker performs the best in terms of early detection. Therefore, the objective was, to map the methodological and reporting quality of available oral squamous cell carcinoma (OSCC) or head/neck squamous cell carcinoma (HNSCC) systematic reviews and meta-analysis. Secondly, to evaluate diagnostic accuracy of salivary biomarkers for common craniofacial cancers and to compare the diagnostic value of different salivary biomarkers.PubMed, Scopus, Web of Science, Embase and Cochrane Library electronic databases were used to map the methodological and reporting quality of the systematic reviews and meta-analysis conducted on the HNSCC, OSCC using the AMSTAR-2 checklist. The inclusion criteria were systematic reviews and meta-analysis published in the topic of HNSCC and OSCC biomarkers. Exclusion criteria were no animal studies; original primary studies, due to limitation of competency in other languages articles with language other than English were excluded. The sensitivity and specificity were calculated for salivary biomarkers and ranked according to network meta-analysis principles.A total of N = 5893 patients were included from four meta-analysis studies. All together, these included n = 37 primary studies. n = 94 biomarkers were pooled from these four meta-analyses and categorised into the stages at which they were detected (I-IV). In OSCC, Chemerin and MMP-9 displayed the highest sensitivity, registering 0.94 (95% CI 0.78, 1.00) and a balanced accuracy of 0.93. Phytosphingosine closely followed, with a sensitivity of 0.91 (95% CI 0.68, 0.99) and a balanced accuracy of 0.87.For HNSCC, the top three biomarkers are Actin, IL-1β Singleplex, and IL-8 ELISA. Actin leads with a sensitivity of 0.91 (95% CI 0.68–0.99), a specificity of 0.67, and an overall accuracy of 0.79. Subsequently, IL-1β Singleplex exhibits a sensitivity of 0.62 (95% CI 0.30–0.88), a specificity of 0.89, and an accuracy of 0.75, followed by IL-8 ELISA with a sensitivity of 0.81 (95% CI 0.54–0.97), a specificity of 0.59, and an accuracy of 0.70.In conclusion, there was highest sensitivity for MMP-9 and chemerin salivary biomarkers. There is need of further more studies to identify biomarkers for HNSCC and OSCC.

Since rice blast is a disease that causes significant damage to rice all over the world, the intensive development of disease-resistant genotypes is of great urgency. The use of molecular biology technologies, new biotechnological approaches and molecular genetic methods allows creating disease-resistant varieties while reducing the time of their development, which plays an important role in growing competitive products. The current paper has highlighted the results of estimating rice samples developed at the FSBSI “ARC “Donskoy” for blast resistance. The objects of the study were new samples developed in the laboratory of rice breeding and seed production. In 2022–2023, there were screened one hundred eighty-seven rice samples. They were identified on a presence of the blast resistance gene Pi-2. One hundred fifteen samples were estimated for the blast resistance gene Pi-b. Genomic DNA was isolated from young rice leaves. After estimating the quantity and quality of the isolated DNA there was conducted a polymerase chain reaction for the target genes Pi-2 and Pi-b. In order to identify the alleles of the desired genes there were used specific intragenic molecular SSR markers of dominant (for Pi-2) and codominant (for Pi-b) types. Electrophoresis of the obtained amplicons was performed on 2 % agarose gels during an hour. The results of the analysis were recorded in ultraviolet light and processed in ImageLab 5.1 software. As a result of the conducted study, there were identified new rice breeding samples that carry blast resistance genes Pi-2 and Pi-b. These samples are recommended for use in the further breeding process for blast resistance.

Apple scab, caused by Venturia inaequalis, is one of the most damaging pathogens affecting apple species. Cross combinations were made between the Salva cv. (female parent), a valuable local cultivar known for its fruit quality and used as a donor of the Vf resistance gene, and Jonathan (male parent), a variety widely cultivated but susceptible to scab. The Vf gene was first identified in Malus floribunda Clone 821, which was subsequently transferred to commercial varieties through various breeding programs. To confirm the presence of the Vf gene, the progeny from this cross was tested using Marker-Assisted Selection (MAS) with one dominant primer pair (AM19) and two codominant primers (AL07 and VFC) to distinguish between homozygous and heterozygous genotypes. From the crossing, 67 hybrids were obtained, of which 35.8% (24 hybrids) were classified as resistant (heterozygous - Vfvf), while 64.2% (43 hybrids) were classified as susceptible (recessive homozygotes - vfvf). This population of hybrids resistance to Venturia inaequalis represents a good starting point in obtaining cultivars with resistance to scab.

Atopic dermatitis (AD) is a chronic recurrent inflammatory disease accompanied by severe itching. One of the leading mechanisms underlying the development of AD is an imbalance of the Th1/Th2 cells immune response, which leads to an increased production of inflammatory mediators, including IL-1 family. The IL-1 family includes the recently discovered IL-33 and IL-37, and their role in the pathogenesis of AD has been actively studied. IL-33 functions as an alarmin that can induce IL-31 production, thereby leading to skin barrier impairment, pruritus and scratching. Having both immunomodulatory and immunosuppressive properties, IL-37 suppresses leukocyte infiltration of the affected skin and reduces the activity of proinflammatory cytokines. The aim of our study was to search for associations between gene polymorphisms of IL33, IL37 genes, and risk of AD. A total of 98 patients with moderate and severe AD were included in the study. The control group included 72 healthy volunteers. Polymorphic markers were determined in peripheral blood. After extraction of total RNA, polymorphic markers rs7019575 in the IL33 gene, rs3811046 and rs3811047 in the IL37 gene were analyzed using RT-PCR. There was no statistically significant difference in allele frequency and genotype distribution of rs7019575 (IL33) and rs3811047 (IL37). Studying the rs3811046 polymorphic marker in the IL37 gene showed that the risk of AD was almost 2 times lower for the G allele carriers and more than 2-fold higher for TT homozygous carriers. The haplotype analysis revealed that the GTAA and TTGG haplotypes of IL37 were associated with AD, thus increasing the risk of AD development by 2 and 10 times, respectively. In conclusion, SNP markers identified in this study can be used to predict the risk of AD development in the subjects with a positive family history of atopic diseases.

Abstract Background Groundnut is mainly grown in the semi-arid tropic (SAT) regions worldwide, where abiotic stress like drought is persistent. However, a major research gap exists regarding exploring the genetic and genomic underpinnings of tolerance to drought. In this study, a multi-parent advanced generation inter-cross (MAGIC) population was developed and evaluated for five seasons at two locations for three consecutive years (2018–19, 2019–20 and 2020–21) under drought stress and normal environments. Results Phenotyping data of drought tolerance related traits, combined with the high-quality 10,556 polymorphic SNPs, were used to perform multi-locus model genome-wide association study (GWAS) analysis. We identified 37 significant marker-trait associations (MTAs) (Bonferroni-corrected) accounting, 0.91- 9.82% of the phenotypic variance. Intriguingly, 26 significant MTAs overlap on four chromosomes (Ah03, Ah07, Ah10 and Ah18) (harboring 70% of MTAs), indicating genomic hotspot regions governing drought tolerance traits. Furthermore, important candidate genes associated with leaf senescence (NAC transcription factor), flowering (B3 domain-containing transcription factor, Ulp1 protease family, and Ankyrin repeat-containing protein), involved in chlorophyll biosynthesis (FAR1 DNA-binding domain protein), stomatal regulation (Rop guanine nucleotide exchange factor; Galacturonosyltransferases), and associated with yield traits (Fasciclin-like arabinogalactan protein 11 and Fasciclin-like arabinogalactan protein 21) were found in the vicinity of significant MTAs genomic regions. Conclusion The findings of our investigation have the potential to provide a basis for significant MTAs validation, gene discovery and development of functional markers, which could be employed in genomics-assisted breeding to develop climate-resilient groundnut varieties.

The purpose of this study is to identify ethnopoetic markers in a translingual literary text. A translingual text is a text created by an author in a language that is not his or her native language and that transmits fragments of the author’s original culture. By ethnopoetic markers we mean such elements of the text that 1) are transferred into the fabric of the Russian-language text and have an exophonic sound, therefore, are semantically lacunary for the reader and require expansion; 2) are neutral from the point of view of the translator language, but reproduce foreign images of the world. The material for the study was selected poems by the Tatar poetess Albina Absalyamova. In the course of the work, it was possible to establish that the category of translingual text as a scientific problem is closely intertwined with the epistemological fields of ethnoand geopoetics.

Rationale: Long non-coding RNAs (lncRNAs) influence tumor cell properties during the onset and progression of lung malignancies; however, their diagnostic and prognostic significance has not been determined. We have previously shown that when non-small cell lung cancer (NSCLC) cells acquire a more malignant phenotype (under the influence of macrophagal cytotoxic activity) compared to the original cell lines, the expression of several lncRNAs, in particular PSMB8-AS1, MBNL1-AS1, and OLMALINC, is altered compared to the original cell lines. Aim: A comparative analysis of lncRNAs PSMB8-AS1, MBNL1-AS1, and OLMALINC expression in tissue samples from lung tumors and conditionally normal areas of the lungs and an assessment of the lncRNAs clinical significance. Methods: We have analyzed surgical samples of the tumor and conditionally normal tissue from 16 patients with a verified diagnosis of NSCLC. The expression level of lncRNAs PSMB8-AS1, MBNL1-AS1 and OLMALINC was assessed by real-time polymerase chain reaction. To analyze the long-term treatment results and clinical significance of the studied genes, the patients were divided into two comparison groups depending on the relative level of lncRNAs expression (above or below the median). Results: The expression of lncRNAs PSMB8-AS1, MBNL1-AS1 and OLMALINC in the lung tumor tissue was significantly reduced compared to the conditionally normal tissues (p = 0.0034; p = 0.002 and p = 0.0172, respectively). Analysis of the association between the expression of these lncRNAs with clinical and morphological characteristics, such as disease stage, tumor size, presence of regional and distant metastases was unable to identify any regular patterns. The expression of lncRNAs PSMB8-AS1, MBNL1-AS1 and OLMALINC was not a significant prognostic factor (p = 0.364; p = 0.759 and p = 0.184, respectively). However in the case of high OLMALINC and PSMB8-AS1 expression, median survival was 47 months, while in the case of their low expression, median survival was not achieved during the follow-up. The expression of lncRNA PSMB8-AS1 in NSCLC tumors positively correlated with the expression of lncRNA OLMALINC (r = 0.680, p = 0.007), which may indicate their functional interplay or the presence of common regulatory mechanisms. Conclusion: The NSCLC tumors demonstrated aberrant expression of PSMB8-AS1, MBNL1-AS1, and OLMALINC lncRNAs. A more detailed study of their expression in various cell types and their regulatory role would allow for validation of new therapeutic targets in NSCLC, as well as for development of alternative therapies.

BACKGROUND: At present, there are some limitations in evaluating the severity of acute spinal cord injury, and a rapid and accurate evaluation method is urgently needed. OBJECTIVE: To analyze the correlation between the expression levels of serum oxidative stress and nerve injury indexes and the severity of the disease in patients with acute spinal cord injury. METHODS: A total of 65 patients were included in the study from August 2020 to May 2022, including 32 patients in the experimental group (acute spinal cord injury) and 33 patients in the control group (simple spinal fracture). American Spinal Injury Association (ASIA) Impairment Scale and neurological function score were evaluated within 8 hours of admission. Meanwhile, serum levels of superoxide dismutase, malondialdehyde, glutathione, nitric oxide, glial fibrillary acidic protein and neuron-specific enolase were detected and compared between the two groups. The correlation between the expression levels of the above serological indicators in serum and ASIA impairment grade and AISA neural function score was analyzed. RESULTS AND CONCLUSION: The average serum levels of superoxide dismutase and glutathione in the experimental group were significantly lower than those of the control group (P < 0.001), while the average serum levels of malondialdehyde, nitric oxide, glial fibrillary acidic protein and neuron-specific enolase in the experimental group were higher than those of the control group (P < 0.01). The serum levels of superoxide dismutase and glutathione in the experimental group were positively correlated with the damage grade of AISA (r=0.862 4, 0.849 3, P < 0.01), while the serum levels of malondialdehyde, nitric oxide, glial fibrillary acidic protein and neuron-specific enolase were negatively correlated with the damage grade of AISA (r=-0.866 1, -0.638 1, -0.746 6, P < 0.001), and the serum level of nitric oxide was not significantly correlated with the damage grade of AISA (r=-0.177 5, P > 0.05). The serum level of glutathione in the experimental group was positively correlated with AISA sensory function scores (r=0.569 9, P < 0.001), while the serum levels of malondialdehyde, glial fibrillary acidic protein and neuron-specific enolase were negatively correlated with AISA sensory function scores (r=-0.574 1, -0.099 2, -0.708 6, P < 0.05), and the serum levels of superoxide dismutase and nitric oxide were not significantly correlated with AISA sensory function scores (r=0.230 8, -0.376 2, P > 0.05). The serum levels of superoxide dismutase and glutathione in the experimental group were positively correlated with ASIA motor function scores (r=0.380, 0.524 7, P < 0.05); the serum levels of malondialdehyde, glial fibrillary acidic protein and neuron-specific enolase were negatively correlated with AISA motor function scores (r=-0.577 9, -0.452 2, -0.662 8, P < 0.05); and the level of nitric oxide had no significant correlation with AISA motor function scores (r=-0.049 7, P > 0.05).To conclude, the serum levels of superoxide dismutase, malondialdehyde, glutathione, nitric oxide, glial fibrillary acidic protein and neuron-specific enolase in serum of patients with acute spinal cord injury are significantly correlated with ASIA impairment grade and ASIA neural function score, which could be used as biomarkers for early clinical assessment of disease severity.

Purpose: Identifying high-risk populations and diagnosing gastric cancer (GC) early remains challenging. This study aimed to establish and verify a nomogram model for the early diagnosis of GC based on conventional laboratory indicators. Methods: We performed a retrospective analysis of the clinical data of 2,770 individuals with first diagnosis of GC and 1,513 patients with benign gastric disease from January 2018 to December 2022. The cases were divided into the training set and validation set randomly, with a ratio of 7:3. Variable screening was performed by least absolute shrinkage and selection operator (LASSO) and logistic regression analysis. A nomogram was constructed in the training set to assist in the early diagnosis of GC. Results: There were 4283 patients included in the study, with 2998 patients assigned in the training set and 1285 patients in the validation set. Through LASSO regression and logistic regression analysis, independent variables associated with GC were identified, including CEA, CA199, LYM, HGB, MCH, MCHC, PLT, ALB, TG, HDL, and AFR. The nomogram model was constructed using the above 11 independent indicators. The AUC was 0.803 for the training set and 0.797 for the validation set, indicating that the model showed high clinical diagnostic efficacy. The calibration curves and decision curve analysis (DCA) of the nomogram presented good calibration and clinical application ability. Conclusion: Based on the analysis of large sample size, we constructed a nomogram model with 11 routine laboratory indicators, which showed good discrimination ability and calibration.

Objectives: We evaluated the ability and accuracy of preoperative identification and localization of sentinel lymph nodes (SLNs) using intradermal injection of ultrasound contrast agent. Materials and methods: Prospectively recruited 191 early breast cancer patients with clinically negative axillary lymph nodes (ALNs). All participants received intradermal injection of microbubble contrast agent. Following the identification and localization of SLNs using contrast-enhanced ultrasound (CEUS), Markers were deployed in the SLNs US-guided. Subsequently, the SLNs with Markers were stained and marked with a suspension of nano-carbon US-guided to assist in intraoperative localization of SLNs. Standard SLNB with methylene blue tracing was performed intraoperatively to assess the consistency between the two methods of SLNs localization, thereby determining the ability and accuracy of CEUS in identifying and localizing SLNs. Results: A total of 179 patients were included in the final evaluation analysis, in which a microbubble contrast agent was injected subcutaneously in the areolar region. A total of 201 SLNs were identified, with a median of 1 SLN per patient. Each SLN was identified in 157 patients, and two SLNs were identified in 22 patients. Among the 201 SLNs from the 179 patients, the proportion that could be individually matched between CEUS and the blue dye method was 95.5% (192/201), and the consistency evaluation in SLNs identification between CEUS and blue dye staining was excellent (Kappa value = 0.62, P < 0.001). Conclusion: The consistency of identification and localization of SLNs in early breast cancer patients between CEUS and the blue dye method was strong. [ABSTRACT FROM AUTHOR]

Context: Internationally, undigestible neutral detergent fibre (uNDF) has become a standard feed analysis to quantify the potential digestible NDF fraction and to be an internal marker to estimate diet total-tract digestibility in animal studies. However, this analysis is labour-intensive/expensive and not commercially available in New Zealand and many other countries. Aim: To compare the uNDF after rumen incubation determined for various forages by using filter bags that can be used sequentially for NDF and uNDF analysis with the standard method using Saatifil bags. Methods: Freeze-dried material of 15 forage samples (mainly dicotyledons) was weighed into three types of bags (Saatifil, 12 μm; F57, 25 μm; F58, 6–9 μm) in sextuplicate and then incubated across two runs for 12 days in the rumen of a fistulated non-lactating pasture-fed dairy cow. After incubation, the NDF of the residue was determined. Key results: Overall, the average (±within forage sample CV%) uNDF was 5.4% (9.8), 6.7% (15.2) and 6.3% (16.0) of DM for Saatifil, F57 and F58, respectively, and the mean bias (±95% confidence interval, CI) was 1.3 (0.3–2.3) and 1.2 (−0.1–2.5) for F57 and F58 versus Saatifil respectively. The 95% CI indicated that the intercept and slope for the orthogonal regression of F57 and F58 versus Saatifil were not different from zero and one, respectively, and the correlation for F57 with Saatifil was stronger than for F58 (r = 0.65 and 0.40 respectively). Conclusions: Both F57 and F58 bags resulted in similar uNDF values as with the Saatifil bag; however, numerically uNDF values were greater and with a large within-sample CV. Implications: The results of the current study suggest that the F57 bag is suitable for uNDF determination, but that some further modifications to the protocol need to be made to improve the accuracy and precision of the uNDF determination. Undigestible neutral detergent fibre (uNDF) has become a standard feed analysis overseas to properly quantify forage digestibility. However, this analysis is not available locally in New Zealand and the method implemented in our laboratory by using an alternative bag (F57) was not validated. The results of the current validation suggest that the F57 bag is suitable for uNDF determination, but that some further modifications to the protocol need to be made to improve the accuracy and precision of the uNDF determination.

Background/Objectives: Salivary immunoglobulin A (IgA) is a mediator of local immunity and host defence. Altered IgA levels may predispose to bacterial invasion of the mucosa in the gastrointestinal tract, including the oral cavity. Our study aimed to present the diagnostic trends related to salivary IgA in health and disease based on a bibliometric analysis of published papers between 2009 and 2024. Methods: By 14 September 2024, 1247 English original articles were found in the database Web of Science. We selected 838 records considering the diagnostic usefulness of IgA in human subjects. Based on bibliographic data, we created citation and keyword co-occurrence maps using VOSviewer 1.6.20. Results: Most articles belonged to the "Sport Sciences" category (n = 169), followed by the "Immunology" category (n = 93). The Brazilian researcher Alexandre Moreira from the University of Sao Paulo had the most published and most frequently cited papers. Most of the included articles came from the USA (n = 158), England (n = 105), Brazil (n = 95), and Japan (n = 95). The most cited article described research on IgA in response to SARS-CoV-2 infection (n = 690), but the subsequent two papers considered the role of salivary IgA in the dysbiosis of the intestinal microbiota in inflammatory bowel diseases (n = 272) and the formation of systemic immune responses from the gastrointestinal tract (n = 245). Conclusions: Salivary IgA is a widely evaluated diagnostic marker in both patients and healthy individuals. Numerous reports have identified its changes as a result of physical exertion in various groups of athletes, during infections (including SARS-CoV-2) and in the course of local diseases (e.g., periodontal disease) or systemic diseases (e.g., inflammatory bowel disease).

Simple Summary: Variably known as wild boar, feral pigs, wild hogs, and other names, Sus scrofa is a highly invasive species present on every continent except Antarctica. Free-ranging pigs often negatively impact the ecosystem and have the potential to spread impactful pathogens to domestic livestock. Countermeasures taken to control population size and/or reduce the circulation of infectious diseases are based on the delivery of baits containing bioactive chemicals or vaccines, e.g., classical swine fever vaccine. The efficacy of these methods is reliant on the consumption of baits by the pigs and tracers, i.e., rhodamine B, tetracycline, and iophenoxic acid, are commonly used to quantitate bait uptake in free-ranging pig population studies. All three tracers have been shown to be highly effective for this purpose, but, as reviewed herein, their persistence in animals and the methods for detecting their presence in pigs vary. Safer, non-infectious tracers that persist in pigs and can be easily detected through non-invasive methods are needed for population studies in both free-ranging and farm-raised pigs. A highly invasive species, free-ranging Sus scrofa often negatively impact the ecosystem and are capable of spreading a number of impactful pathogens to domestic livestock. Measures taken to ameliorate these impacts and/or control population size are based on the delivery of oral baits containing bioactive chemicals or vaccines, e.g., classical swine fever vaccine. The efficacy of these methods depends on the rate at which inoculated baits are consumed by the pigs. Rhodamine B, tetracycline, and iophenoxic acid are commonly used to quantitate bait uptake in free-ranging pig population studies. All three are effective in this application but differ in fundamental characteristics. When used as a tracer, the effective dose of rhodamine B was established at 15 mg/kg to ensure a 12-week window of detection based on evaluation of hair samples using fluorescent microscopy. Tetracyclines are likewise effective tracers in free-ranging pigs, but the process of detection is highly invasive, i.e., requires euthanasia, and extraction of bone or teeth, followed by examination by fluorescence microscopy. Iophenoxic acid and its derivatives also highly suitable tracers and may be detected in serum for ≥9 months after exposure. Notably tracers used in free-ranging pigs are not suitable for behavioral studies in farm-raised pigs either because the detection method is highly invasive (tetracyclines) or because they are unapproved for use in meat destined for human consumption.

Pregnancy of unknown location (PUL) is a temporary pathologic or physiologic phenomenon of early pregnancy that requires follow up to determine the final pregnancy outcome. Evidence indicated that PUL patients suffer a remarkably higher rate of adverse pregnancy outcomes, represented by ectopic gestation and early pregnancy loss, than the general population. In the past few decades, discussion about PUL has never stopped, and a variety of markers have been widely investigated for the early and accurate evaluation of PUL, including serum biomarkers, ultrasound imaging features, multivariate analysis, and the diagnosis of ectopic pregnancy based on risk stratification. So far, machine learning (ML) methods represented by M4 and M6 logistic regression have gained a level of recognition and are continually improving. Nevertheless, the heterogeneity of PUL markers, mainly caused by the limited sample size, the differences in population and technical maturity, etc., have hampered the management of PUL. With the advancement of multidisciplinary integration and cutting‐edge technologies (e.g. artificial intelligence, prediction model development, and telemedicine), novel markers, and strategies for the management of PUL are expected to be developed. In this review, we summarize both conventional and novel markers (represented by artificial intelligence) for PUL assessment and management, investigate their advancements, limitations and challenges, and propose insights on future research direction and clinical application. Synopsis: This review summarized the conventional markers (represented by hCG) and modern markers (represented by an AI model) of pregnancy of unknown location. [ABSTRACT FROM AUTHOR]

HEAD & neck cancer ,SQUAMOUS cell carcinoma ,MOUTH tumors ,ORAL cancer ,CHEMERIN - Abstract
Oral cancer became a very common condition. WHO estimates that there are 4 cases of lip and oral cavity cancer for every 100,000 people worldwide. The early diagnosis of cancers is currently a top focus in the health sector. Recent systematic reviews and meta-analyses have identified promising biomarkers for early detection in several original research investigations. However, it is still unclear the quality of these evidence and which biomarker performs the best in terms of early detection. Therefore, the objective was, to map the methodological and reporting quality of available oral squamous cell carcinoma (OSCC) or head/neck squamous cell carcinoma (HNSCC) systematic reviews and meta-analysis. Secondly, to evaluate diagnostic accuracy of salivary biomarkers for common craniofacial cancers and to compare the diagnostic value of different salivary biomarkers. PubMed, Scopus, Web of Science, Embase and Cochrane Library electronic databases were used to map the methodological and reporting quality of the systematic reviews and meta-analysis conducted on the HNSCC, OSCC using the AMSTAR-2 checklist. The inclusion criteria were systematic reviews and meta-analysis published in the topic of HNSCC and OSCC biomarkers. Exclusion criteria were no animal studies; original primary studies, due to limitation of competency in other languages articles with language other than English were excluded. The sensitivity and specificity were calculated for salivary biomarkers and ranked according to network meta-analysis principles. A total of N = 5893 patients were included from four meta-analysis studies. All together, these included n = 37 primary studies. n = 94 biomarkers were pooled from these four meta-analyses and categorised into the stages at which they were detected (I-IV). In OSCC, Chemerin and MMP-9 displayed the highest sensitivity, registering 0.94 (95% CI 0.78, 1.00) and a balanced accuracy of 0.93. Phytosphingosine closely followed, with a sensitivity of 0.91 (95% CI 0.68, 0.99) and a balanced accuracy of 0.87. For HNSCC, the top three biomarkers are Actin, IL-1β Singleplex, and IL-8 ELISA. Actin leads with a sensitivity of 0.91 (95% CI 0.68–0.99), a specificity of 0.67, and an overall accuracy of 0.79. Subsequently, IL-1β Singleplex exhibits a sensitivity of 0.62 (95% CI 0.30–0.88), a specificity of 0.89, and an accuracy of 0.75, followed by IL-8 ELISA with a sensitivity of 0.81 (95% CI 0.54–0.97), a specificity of 0.59, and an accuracy of 0.70. In conclusion, there was highest sensitivity for MMP-9 and chemerin salivary biomarkers. There is need of further more studies to identify biomarkers for HNSCC and OSCC. • Methodological and reporting quality of systematic reviews and meta-analysis was more than 50% based on AMSTAR-2 assessment. • UPLC-MS (31.79%) was the most used method to detect the salivary biomarkers followed by RT-qPCR (11.26%). • Chemerin & MMP-9 show top sensitivity in OSCC followed by Phytosphingosine. • Top 3 biomarkers for HNSCC are Actin, IL-1β Singleplex and IL-8 ELISA. • Top biomarkers in early OSCC I-II: chemerin, MMP-9, Phytosphingosine, Pipecolinic acid.

- Abstract
Background: Cashew (Anacardium occidentale L.) is a widely cultivated tree with great economic significance. In cashew, several elite cultivars have been developed for commercial cultivation, which form the underpinning for the cashew-based industries and the several billion-dollar world trade. However, frequently the genetic purity of the planting material is not maintained, resulting in great economic losses. Therefore, there is a need to develop a reliable method for the identification of cultivars to avoid economic losses to the cultivators and the protection of cultivars by the breeders. Methods and results: In this study, 35 new microsatellite/simple sequence repeat (SSR) markers were developed, and a set of 20 highly polymorphic and reproducible markers were used for DNA fingerprinting and genetic diversity analysis in 32 cashew cultivars. The polymorphic information content (PIC) of newly developed markers varied from 0.19 to 0.67, with an average of 0.44. The probability of identifying any two genotypes with identical fingerprints using the 20 SSR markers used for fingerprinting here in cashew cultivars was less than 2.8 × 10
–11 . Of the set of 20 markers, eight were sufficient for uniquely fingerprinting all the cultivars. Genetic diversity analysis by the neighbor-joining (NJ) method grouped 32 cultivars into three main clusters, and the grouping had no relationship to the geographic regions or the pedigree. Conclusions: The findings of this study are useful for the conservation and protection of cultivars under the PVP Act for ensuring the trading of quality planting material and are also useful for cashew breeding programs.

TUMOR markers ,EARLY detection of cancer ,URINALYSIS ,BLADDER cancer ,MICROSATELLITE repeats - Abstract
Bladder cancer (BC) is the most common neoplasm of the urinary system and ranks tenth in global cancer incidence. Due to its high recurrence rate and the need for continuous monitoring, it is the cancer with the highest cost per patient. Cystoscopy is the traditional method for its detection and surveillance; however, this is an invasive technique, while non-invasive methods, such as cytology, have a limited sensitivity. For this reason, new non-invasive strategies have emerged, analyzing useful markers for BC detection from urine samples. The identification of tumor markers is essential for early cancer detection and treatment. Urine analysis offers a non-invasive method to identify these markers. Microsatellite instability (MSI) has been proposed as a promising marker for tumor cell detection and guided targeted therapies. Therefore, this review aims to explore the evidence supporting the identification of MSI in exfoliated bladder tumor cells (EBTCs) in the urine, emphasizing its potential as a non-invasive and clinically effective alternative for tumor identification. Furthermore, establishing clinical guidelines is crucial for standardizing its application in oncological screening and validating its clinical utility. [ABSTRACT FROM AUTHOR]

OVARIAN cancer ,PROTEIN expression ,CANCER patients ,TUMOR markers ,STATISTICS - Abstract
Background: Ovarian cancer is one of the most common cancers in women. Markers associated with ovarian cancer are still being sought. The aim of this study was to evaluate the expression of BRIP-1 (FANCJ) and FANCI proteins in ovarian cancer tissue and to assess these expressions in differentiating the described clinical features. Methods: The study enrolled 68 patients with ovarian cancer. The cohort was divided into a HGSOC (high-grade serous ovarian cancer) group and a non-HGSOC group, which represented ovarian cancer other than HGSOC. Immunohistochemical evaluation of FANCI and BRIP-1 (FANCJ) protein expression in ovarian cancer tissue samples was performed. All statistical analyses were performed using StatView software (Carry, NC, USA). Results: The FANCI protein mostly showed moderate positive and strong positive expression, while BRIP-1 protein mostly showed no expression or positive expression. Patients with lower expression of FANCI and BRIP-1 showed differences in the clinical stage of HGSOC, which was not observed in patients with higher expression of these proteins. In addition, patients with lower BRIP-1 expression showed differences in menopausal status, which was not observed in patients with higher expression of this protein. Conclusions: This study shows that FANCI protein is a marker associated with lower FIGO stage and histologically high-grade cancer in a group of all ovarian cancers and in non-HGSOC.

BACKGROUND: Pancreatic carcinoma is one of the most severe oncological diseases of the gastrointestinal tract. At the time of diagnosis, up to 28% of patients have metastatic liver damage, and only 5% of patients survive five years. Scientific research focuses on non-invasive markers that could help screen for the disease and identify patients more quickly. Potential biomarkers also include matrix metalloproteinases, which play a role in oncogenesis. MATERIAL AND METHODS: We prospectively followed 46 patients with pancreatic cancer and benign pancreatic diseases from September 2022 to March 2023. We determined the level of MMP9 in serum and tissue biopsied during surgeries. RESULT: As a result, MMP9 levels were elevated from the T2 stage. The correlation between disease stage and MMP9 level was not confirmed in lower stages, possibly due to the small group of patients. CONCLUSION: MMP9 seems suitable for detecting late stages of pancreatic cancer, possibly for secondary prevention. We could not confirm a correlation between MMP9 levels and the initial stages of the disease. [ABSTRACT FROM AUTHOR]

Aim Methods Results Conclusion Novel markers to reflect the intestinal damage in coeliac disease are needed. We studied the potential of faecal and serum neopterin, and faecal myeloperoxidase, human β‐defensin‐2, and lipocalin‐2 in a case–control study.Data were collected from medical records and a biobank including newly diagnosed coeliac disease patients, potential coeliac disease patients and non‐coeliac controls. Commercially available ELISA assays were used for measuring the biomarkers.Altogether 19 patients with coeliac disease (median age 9.0 years), 8 with potential coeliac disease (4.0 years) and 18 controls (6.5 years) were included. The highest faecal neopterin levels were seen in potential coeliac disease, followed by controls and coeliac disease (median 513 vs. 372 vs. 255 nmol/L, respectively, p = 0.016). Also, serum neopterin was highest in the potential coeliac disease group (9.8 vs. 5.5 vs. 5.9 nmol/L, p = 0.022). After age adjustment and robust variance estimation, only differences in serum neopterin remained significant. Other markers did not differ between the groups. None of the markers were significantly associated with serum transglutaminase‐2 antibody levels.Differences in neopterin levels amongst patients with potential coeliac disease, coeliac disease, and controls suggest that neopterin might serve as an early disease marker.
