Objective. To study the problem in esophageal cancer, the function of SOX2 and miR-126 has not been completely explored. The objective of this study was to find out how SOX2 and miR-126 act in esophageal cancer and their relation to the clinical and prognostic features. Methods. The expression of SOX2 and miR-126 was properly assessed in the carcinoma of the esophagus, and the nearby healthy tissues surgically excised from 35 included patients. Results. SOX2 was elevated in esophageal cancer relative to normal tissues contrary to the miR-126 levels. This inverse relationship was linked to adverse clinical features. Background. SOX2 has been involved as an oncogene in various types of malignant tumors; microRNA-126 (miR-126) is extensively expressed in vascular endothelial cells, which control angiogenesis. Furthermore, many published reports reasonably concluded that based on the prime characteristic of malignant cells, miR-126 may act appropriately as a promotor or a suppressor for the malignant growth. Conclusion. In esophageal cancer, SOX2 works as an oncogene, whereas miR-126 acts as a tumor suppressor gene. SOX2 overexpression and miR-126 downregulation were shown to be linked to a poor prognosis.

Salmonella enterica serovar Typhi is Gram negative, rod shaped, facultative anaerobic bacterium, belongs to enterobacteriaceae family that causes typhoid fever in humans. This bacterium has become a super bug due to acquisition of multi drug resistance. Bacteria is transmitted through food and water contaminated with human feaces. Present study reports the screening of Adhatoda vasica, Amaranthus hybridus and Aloe barbadensis and their evaluation against multi-drug resistant Salmonella enterica serovar Typhi. Qualitative analysis of ten phytochemicals was conducted using chemical method and Gas Chromatography-Mass Spectrometry (GCMS). Antibacterial activity of plants was carried out by agar well diffusion method on Mueller Hinton agar. Total tannins, total alkaloids and total flavonoids of different parts of three plants were estimated through spectrophotometer. Total tannins content in different parts of plants was present in the given order Amaranthus hybridus leaf > Aloe barbadensis leaf > Adhatoda vasica leaf > Adhatoda vasica flower > Adhatoda vasica stem. Whereas, the order of total flavonoid concentration was Amaranthus hybridus leaf > Aloe barbadensis leaf > Adhatoda vasica leaf > Amaranthus hybridus seed. Total alkaloids have order, Adhatoda vasica leaf > Amaranthus hybridus leaf > Adhatoda vasica flower > Amaranthus hybridus seed > Aloe barbadensis leaf. Results of phytochemical analysis suggested that plants have strong profile of antioxidants, total phenolic contents and various enzymes proposing them best alternate to cure bacterial infections. GC-MS analysis further confirmed stronger phytochemical profile that can be utilized as antagonists to Salmonella enterica serovar Typhi.

Background/Aim: Breast cancer (BC) is among the most widespread malignant tumors in women. In the current study, we evaluated the role of miR-31 in BC patients and its relation to the different prognostic, clinical, and pathological features. Patients and Methods: MiR-31 levels were determined by RT-PCR in BC and adjacent normal breast tissues from 100 BC patients. BC diagnosis was established through histopathological examinations. The expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) receptor in all tumors was determined using immunohistochemistry. Results: MiR-31 expression was reduced in BC tissues relative to adjacent healthy breast tissue (mean levels were 0.93 and 7.2, respectively). Also, the low expression of miR-31 in BC patients was significantly correlated with adverse clinical and pathological features such as: young patient’s age, premenopausal status, infiltrative lobular carcinoma, ER and PR negative tumors, HER2 positive tumors, and advanced clinical stage. Conclusion: MiR-31 was expressed at low levels in BC tissues and correlated with adverse clinical and pathological features, and poor survival.

Background/Aim: Vitamin D deficiency accelerates the onset of type 2 diabetes mellitus (T2DM). Polymorphisms in the vitamin D receptor (VDR) have been linked to coronary artery disease (CAD). This study aimed to evaluate the association of vitamin D deficiency and VDR polymorphism with CAD in T2DM. Patients and Methods: A total of 150 adult male and female subjects, aged from 40 to 60 years, were divided into three groups, each with 50 subjects; control group, T2DM, and T2DM with CAD. Fasting blood glucose (FBG), total cholesterol (TC), triglycerides (TG), HDL-C, LDL-C, glycosylated hemoglobin (HbA1c), and 25-hydroxyvitamin D (25-OH D) were assessed. VDR genotypes (BsmI, Taq1 and FOK1) were investigated by polymerase chain reaction fragment length polymorphism. Results: There was a significant negative correlation between serum 25-OH D and FBG, TC, TG, and LDL-C levels, and a positive correlation with HDL-C levels in all diabetic patient groups. The risk of CAD was markedly higher in the group of T2DM with CAD in comparison to the control (p

An ethnomedicinal expedition was conducted to collect and record indigenous knowledge about the use of medicinal plants by local inhabitants of four villages (Chittra, Topi, Pandi, and Kalri) of district Bagh, Azad Jammu and Kashmir. Ethnomedicinal data were obtained from 60 randomly selected local inhabitants of the study area through semi-structured questionnaires and interviews. These data were analyzed quantitatively through different ethnobotanical indices including family importance value, relative frequency of citation, use value (UV), fidelity level (FL), informant consensus factor (ICF), and Jaccard index (JI). our study reported 69 medicinal plants belonging to 39 families. Rosaceae (9 species) was a dominant family of the study area. Herb (54.83%) was dominant growth form of plants used for medicinal purpose. Leaves contributed maximum usage (44.29%) for curing diseases. Decoction (23 records) was most used mode of utilization. Relative frequency of citation and UV ranged from 0.03–0.85 and 0.05–1.17, respectively. There were 4 plant species with 100% FL. Highest ICF (0.88%) was found for gastrointestinal diseases. By comparing results with previous study, JI ranged from 0.54 to 24.43%. Our results found that there were 18 plant species not reported with ethnomedicinal aspect in previous studies from district Bagh region. The research of this study concludes that the area is rich with medicinal plants and the local inhabitant of this area still prefer medicinal plants over allopathic medicines for treating different ailments. Comparative analysis has shown some novel uses of plant species which may be due to cultural differences of the study area. However, awareness and pharmacological study are needed to conserve and unveil pharmaceutically important plants.

BACKGROUND: Low Vitamin D levels associated with obesity have reached an epidemic level all over the world. It has been supposed that the low serum level of Vitamin D3 in obese subjects may be due to an increase in the uptake of Vitamin D3 by adipose tissue. AIM: The current study aimed to investigate the effect of a specially designed exercise program for boosting lipolysis on the Vitamin D level in obese children. METHODS: Thirty obese male children participated in the study. Their age was ranged from 9 to 11 years. The participants were assigned to two groups, Group I (GI) who received endurance exercise (ENE) only and Group II (GII) who received the specially designed exercise for increasing lipolysis (ENE preceded by resistance exercise). Free fatty acids (FFA), glycerol, and 25(OH)D were assessed before and immediately after exercise. RESULTS: FFA and glycerol showed a significant increase in both groups following exercise, while 25(OH)D showed a significant increase only in GII. GII showed significantly higher levels of FFA, glycerol, and 25(OH)D following exercise when it was compared to GI. CONCLUSION: The application of resistance training before ENE could improve the Vitamin D status through increasing the lipolytic activities more than the application of endurance exercise alone.

Background/Aim: DNA methylation is the most studied epigenetic modification in cancer. Ten-eleven translocation enzymes (TET) catalyze the oxidation of 5-methylcytosine (5-mC) to 5-hydroxymethylcytosine (5-hmC) in the DNA. In the current research, we aimed to evaluate the role of 5-hmC and TET enzymes in non-small cell lung cancer (NSCLC) patients and their possible association with outcomes. Patients and Methods: ELISA was used to measure the 5-hmC levels in genomic DNA and qRT-PCR was used to evaluate TET1, TET2, and TET3 mRNAs expression levels in NSCLC tissues and their paired normal controls. Results: The levels of 5-hmC were significantly lower in NSCLC tissues than in normal tissues, with a mean ±SD of 0.28±0.37 vs. 1.84±0.58, respectively (t=22.77, p

Hyperthyroidism is a condition that occurs due to over production of thyroid hormones by the thyroid gland . It can be categorized according to thyroid hormone levels into overt and subclinical hyperthyroidism. Also could be classified into, normal (or high) and low thyroid radioactive iodine uptake according to radioiodine uptake. So, the aim of this study was to evaluate the difference in the clinical profile between hyperthyroid patients and its relation to thyroid scan imaging. Also to avoid prescribing antithyroid medications to patients with thyroiditis, this could lead to hypothyroidism . Materials and methods: This is a prospective cohort study for patients with hyperthyroidism. Patients have been enrolled from Endocrinology Outpatient Clinic at Zagazig University Hospitals in the period from December 2018 to October 2020. Results: patients were divided into two major groups, overt hyperthyroidism (group 1) and subclinical hyperthyroidism (group 2). All patients of group (1) had abnormal thyroid gland examination but, only 50 % of group (2) patients had showed abnormal gland examination (p=

Background/Aim: Type 2 diabetes (T2DM) is a metabolic condition associated with an increased risk of death, morbidity, and vascular problems. This study investigated the association of HIF-1α and dyslipidemia with the incidence of coronary artery disease in Saudi patients with T2DM. Patients and Methods: This study included 100 Saudi patients aged 40-60 years who were attending King Abdulaziz Specialist Hospital in Taif, as well as 50 healthy controls. All were divided into three groups of 50 subjects each: control, patients with T2DM, and patients with T2DM with coronary complications. Serum levels of HIF-1α, fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c %), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were estimated. Results: Serum HIF-1α, FBG, HbA1c %, TC, TG, and LDL-C levels were significantly increased in both groups of patients with diabetes (p

Background/Aim: Cervical cancer remains a major public health concern. The ratio of CD4+:CD8+ T-cells is used to evaluate the immune system function. This study aimed to explore the CD4+:CD8+ T-cell ratio in relation to the glycemic status, inflammatory markers, vitamin D, and vitamin B12 in patients with early diagnosed cervical cancer. Patients and Methods: This is a cross-sectional study. Blood samples were collected for flow cytometry analysis. Information regarding Papanicolaou (Pap) smears and colposcopy investigations were collected from 152 women with type 2 diabetes admitted to East Jeddah Hospital, Jeddah, Saudi Arabia, between January 2018 and January 2021. Results: Patients with early cervical carcinoma and a higher CD4+:CD8+ ratio (>1.2) had a higher C-reactive protein (CRP) level than those with a lower CD4+:CD8+ ratio (Mean±SD=13.75±13.3 vs. 10.85±8.1; p-value=0.034). Patients with early cervical carcinoma, diabetes, and higher CD4+:CD8+ ratio (>1.2) had a higher blood HbA1c percent than those with a lower CD4+:CD8+ ratio. Conclusion: A high CD4+:CD8+ T-cells ratio was associated with an increased HbA1c% and CRP levels in women with diabetes diagnosed with early cervical carcinoma, which can induce inflammation in early diagnosed patients with cervical cancer.

Bisphenol A (BPA) leads to ROS production that considered the core of different inflammatory and chronic obstructive pulmonary diseases. As a natural antioxidant, lycopene plays a significant role in the prevention of many chronic diseases. This study aimed to investigate the possible protective role of lycopene against BPA-induced lung alterations using morphometric, histological, immunohistochemical and biochemical methods. Forty rats aged 3 months were divided into four groups (n=10): control group, lycopene group comprising rats that received lycopene by gavage (10 mg/kg /day) for 30 days, BPA group comprising rats that received BPA by gavage (50 mg/kg/day) for 30 days and lycopene + BPA group. On the 30th day, blood and lung tissue samples were collected for biochemical, histological and immunohistochemical studies. Morphometrical and statistical analyses were performed. The BPA group revealed significantly elevated IL-1B, IL-6, MDA and NO, and it showed significantly reduced IL-10, SOD, CAT and GSH when compared to the control and lycopene + BPA groups. Upon histopathological and immunohistochemical examination, lycopene supplementation improved the BPA-induced alveolar collapse, lymphocytic infiltration, extravasated RBCs and fibrosis. The lycopene + BPA group showed significantly reduced mean percentage of 8-OHdG immunopositive and mean area percentages of Bax and caspase 3 immunopositive cells and significantly reduced mean area percentage of Bcl2 immunopositive cells as compared with the BPA group. Lycopene is a protective agent against BPA-induced lung injury because of its anti-apoptotic, anti-inflammatory and antioxidant effects, as confirmed by biochemical and histological studies.

Aflatoxin (AF) contamination of food products is still a major health issue globally. Prior studies suggest that exposure to AFs during pregnancy has harmful fetal outcomes. This preliminary study was designed to assess serum AFB1 levels in neonatal jaundice (NNJ) secondary to glucose-6-phosphate dehydrogenase (G6PD) deficiency. Twenty-four full-term neonates with hemolytic jaundice secondary to G6PD deficiency were enrolled in the study. Erythrocyte G6PD status was assessed colorimetrically, and serum aflatoxin B1 (AFB1) concentrations were measured by high-performance liquid chromatography. The results revealed that AFB1 was detected in 58% (14/24) of the studied newborns while detected in 75% (18/24) of their mothers. AFB1 positive cases had a highly significantly lower birthweight and G6PD activity (P = 0.001, each). Birthweight (r = − 0.574, P = 0.032) and G6PD activity (r = − 0.585, P = 0.028) negatively correlated with serum AFB1 levels while serum alanine aminotransferase activity positively correlated with serum AFB1 levels (r = 0.536, P = 0.048). Maternal AFB1 exposure is associated with adverse birth outcomes as verified by the low birthweight and the evident decline in the activity of G6PD enzyme with the resultant hemolytic NNJ.

The current study evaluated the impact of obesity and its related complications on the course of COVID-19 in Egyptian patients.Methods: We included 230 COVID-19 Egyptian patients from Tanta City. According to their body-mass index (BMI), patient were divided into three groups: normal weight (BMI < 25 kg/m2), overweight (BMI > 25–< 30 kg/m2), and obese (BMI ≥ 30 kg/m2). Patients’ glycemic status, lipid profile, and serum levels of acute-phase reactants were assessed. The number of patients receiving intensive care and the number of deaths in each group were counted.Results: Mean values of random blood sugar, serum cholesterol, triglycerides, serum ferritin, erythrocyte-sedimentation rate, LDH, CRP, D-dimer levels, and blood pressure were significantly higher in obese patients (165.6, 129.5, 105, 1,873, 26, 403, 56.45, 977.16 and 142/87, respectively) than in normal-weight (97.2, 103.5, 70.4, 479, 17.4, 252, 23.2, 612.4, and 118.6/76.8, respectively) and overweight patients (111.4, 106.3, 78.13, 491.3, 19.8, 269.27, 25.42, 618.4, and 120.3/79.3, respectively). Lymphopenia was also significantly predominant in the obese group. Multivariate logistic regression analysis revealed that elevated serum triglycerides, total cholesterol, low density–lipoprotein cholesterol, blood pressure, ferritin, CRP, and low relative lymphocyte count were significant risk factors in obese COVID-19 patients.Conclusion: Obesity and its related complications increase the risk of presenting a more severe form of COVID-19 in Egyptian patients.Keywords: obesity, COVID-19, Egyptian

Background Ovarian cancer is the most common gynecological malignancy. In patients with advanced ovarian cancer, some biological parameters have prognostic implementations. P27kip1 is an inhibitor of a cycline-dependent kinase, its loss, can contribute to tumor progression. Objective This study aimed to examine the importance of P27KIP1 protein in predicting the prognosis and response to neoadjuvant chemotherapy in patients with advanced ovarian epithelial cancer and to compare the outcomes of immunohistochemistry with Quantitative Real-time PCR. Patients and methods We have studied P27KIP1expression by both immunohistochemistry and Quantitative Real-time PCR from 88 patients with advanced ovarian carcinomas undergone radical debulking surgery and received Paclitaxel followed by Cisplatin every 3 weeks for a total of 6 cycles. We also studied their association with both chemotherapy response and patient survival. Results Nuclear expression of p27KIP1 protein was intense in 86 normal ovarian tissues and 42 of 88 carcinomas. The P27kip1mRNA expression level by qRT-PCR was very low in ovarian cancer tissues relative to its adjacent normal tissues. The results were statistically significant by both methods of determination. p27KIP1 expression was significantly related to good prognostic parameters as low stage tumors, differentiated tumors, absence of ascites, residual disease kip1 by both immunohistochemistry and qRT-PCR with different prognostic parameters revealed no significant difference between both methods in the assessment of these parameters. In 4 years of follow-up, 20.5% of patients were alive without evidence of disease. 6.8% were alive with disease. The disease-related four -year survival rate for the whole group was 28.2%. In multivariate analysis, residual disease, histological type, tumor differentiation, ascites was of independent prognostic significance. Conclusion In ovarian cancer, patients with loss of p27KIP1 expression are at a greater likelihood of disease progression, p27KIP1 may be used as a molecular marker to predict response to chemotherapy and prognosis. Both immunohistochemistry and qRT-PCR have equal reliability in the determination of p27 KIP1.

Cancerous inhibitor of protein phosphatase 2A (CIP2A) has been identified as one of the most commonly altered proteins in human cancers. It blocks the tumor-suppressive action of protein phosphatase 2A (PP2A) complex and enhances malignancy. Thirty-five patients with squamous cell carcinoma of the oral cavity underwent surgical resection of the tumor. CIP2A was assessed by quantitative real-time PCR in the resected tumor tissues and in their adjacent normal tissues. CIP2A was found to be overexpressed in all oral squamous cell carcinoma (OSCC) specimens in comparison to their surrounding normal tissue. CIP2A overexpression was statistically correlated with poor prognostic feature of the tumor. Thus, a high expression level of CIP2A was associated with shorter survival. In conclusion, CIP2A is upregulated in OSCC, and its overexpression is correlated with aggressiveness of the tumor and poor outcome and survival. It may serve as a prognostic marker of OSCC.

Background. Diabetes mellitus type 2 and vitamin D deficiency are both prevalent in the Saudi Arabia. Vitamin D deficiency treatment with supplements carries a risk of intoxication. Aim. The present study is aimed at elucidating the effect of exercise on modulation of metabolic status and vitamin D level in patients with type 2 diabetes mellitus (T2DM). Methods. A sum of 110 type 2 diabetic patients were voluntarily enrolled for the present investigation by dividing them into two separate groups (55 individuals for each group), the diabetic study group and diabetic control group. The diabetic study group was engaged in the training program using treadmill exercise. Laboratory parameters were monitored before and after the training program. Results. There were significant elevation in the diabetic study group compared to diabetic control group regarding postexercise vitamin D level, high-density lipoprotein (HDL) ( p value ≤ 0.001, 0.045; respectively). In addition, triglycerides, low-density lipoprotein (LDL), glycosylated hemoglobin (HbA1C), and homeostatic model assessment-insulin resistance (HOMA-IR) were significantly decreased ( p value < 0.001 for all mentioned parameters). Moreover, there were significant higher level in postexercise parameters as compared to preexercise level in the diabetic study group. Conclusion. The exercise training program improved the metabolic control and vitamin D level after three months of intervention.

Background. Heavy metals in excessive levels are hazardous to ecosystems as they can bioaccumulate in organisms, have toxic effects on biota, and even cause mortality in most life forms. Methodology. The present study consists of two studies; initially, different concentrations of copper were biosorbed by using 1 gm powder of various biosorbents such as orange peels (OP), pomegranate peels (POP), and peanut peels (PP). Furthermore, the biosorbed water was used to irrigate soil when the mung beans were cultivated. The growth parameters of plants growing under induced copper stress and treated with different bioabsorbed waters were also evaluated. Results. The results revealed that, among all biosorbents, the copper biosorption capacity of orange peels was maximum (90%), followed by pomegranate peel. The results of the second experiment exhibited that the plants irrigated with biosorbed water did not show metal toxicity. A remarkable increase in shoot length, shoot fresh weight, and shoot dry weight was observed (29.8 cm, 15.4 g, and 14 g, respectively) when exposed to biosorbent water with peanut peels + 200 mg kg−1 (Cu2+). Similarly, pomegranate peel biosorbed water turned out to be an effective treatment to enhance root length, root fresh weight, and root dry weight (6.81 cm, 4.07 g, and 2.66 g, respectively) and resist against induced heavy metal stress conditions at higher concentration (200 mg kg−1). Furthermore, orange peel biosorbed water elevated the total chlorophyll content and soluble sugar content in mung bean (1.56 mg/g and 1.89 mg/g). The highest tolerance index of mung bean plant grown under the stress of Cu2+ metal was induced by orange peel biosorbed water. Conclusion. Biosorption is an environmentally friendly approach to mitigate heavy metals from the water. The studies showed that agricultural wastes have enough bioabsorption potential and should be used to absorb the heavy metal present in water.

Antibacterial drug-resistant strains are a serious problem of bacterial treatments nowadays and have a concern. The plant exacts of

341 entries comprising of 250 genotypes/lines and 91 gene differentials were tested for leaf rust (Puccinia triticina Erik) in different ecological zones of Punjab during 2016–17 and 2017–18. Each entry was planted in a single 1 m long row and Morocco was used as a spreader. Data on leaf rust severity was recorded once in 3rd week of March during both study years at all locations by following Modified Cobb Scale while the data was recorded three times on 2nd, 22nd and 29th March during 2018 at Faisalabad location to study rust development pattern. The disease severity ranged from 0-100S during 2016–17 and from 0-80S during 2017–18. The genotype HYT 60–5 and the genes Lr-19, Lr-26 and Lr 27+31 showed no disease symptoms at any location during both the study years. These genes can be used for future breeding material development. Area under disease progressive curve (AUDPC), calculated on the basis of periodical readings from Faisalabad, ranged from 0–550 and the susceptible check Morocco has AUDPC value of 600. 120 entries including HYT 60–5 have disease progression 0, which showed that there may be a major gene based resistance in these entries. Area under disease progressive curve/Day (AUDPC/DAY) was calculated for the rest of 130 genotypes to have an understanding of the disease progression pattern and out of which 43 entries have AUDPC/Day value ranging from 1–2 and 28 entries have AUDPC/Day value ranging from 2–3 which revealed that these entries are very useful for use in breeding for durable rust resistance and can be utilized as a parent in back cross and top cross breeding schemes. Material with AUDPC value less than 10 is the best source of resistance against the leaf rust. Varieties/advanced lines, Ujala-16, V-14154, and V-14124 have shown slow rust development and are very good sources of resistance. Similarly, HYT 60–5 has proven an excellent source of resistance. The advance line V-14154 has been approved as a commercial cultivar by the name “Akbar-19”.

As a result, our goal was to explore the effectiveness of serum miRNA-96-5p and miRNA-99a-5p as diagnostic tools in hepatocellular carcinoma (HCC).Patients and methods: Blood samples were collected from 55 patients with HCV-induced HCC, 55 patients with HCV-induced liver cirrhosis, and 55 healthy controls. The expression levels of miRNA-96-5p and miRNA-99a-5p were measured using quantitative RT-PCR.Results: miRNA-96-5p expression levels were increased in HCC patient sera, while miRNA-99a-5p levels were reduced. According to ROC curve analysis, using a combination of circulating miRNA-96-5p, miRNA-99a-5-, and alpha-fetoprotein (AFP) improves the accuracy of diagnoses for HCC, with an area under the curve (AUC) of 0.97, compared to AUCs of 0.82, 0.86, and 0.73, respectively, for the individual biomarkers. Furthermore, the present data suggested that higher serum miRNA-96-5p levels were linked to larger tumors and metastasis, whereas lower serum miRNA-99a-5p levels were exclusively linked to HCC metastasis.Conclusion: Using miRNA-96-5p and miRNA-99a-5p in combination with AFP increased both sensitivity and specificity for the diagnosis of HCC. Furthermore, serum levels were linked to tumor size and metastasis. These findings suggested that serum miRNA-96-5p and miRNA-99a-5p could be used as non-invasive biomarkers for the diagnosis of HCC.Keywords: hepatocellular carcinoma, biomarkers, microRNA-96-5p, microRNA-99a-5p

The acquisition of multi-drug resistance (MDR) genes by pathogenic bacterial bugs and their dispersal to different food webs has become a silent pandemic. The multiplied use of different antibacterial therapeutics during COVID-19 pandemic has accelerated the process among emerging pathogens. Wild migratory birds play an important role in the spread of MDR pathogens and MDR gene flow due to the consumption of contaminated food and water.

Continuous scientific research is necessary to help in the discovery of new promising remedies for the treatment of COVID-19, caused by the SARS-CoV-2 virus. This current research was aimed at identifying potential novel inhibitors of the SARS-CoV-2 main protease, which represents one of the most important targets in the viral life cycle. Protein data bank file ID: 7JQ2 was used containing the co-crystallized inhibitor MPI5 with the Main protease. A virtual screening process for natural evodiamine compounds was performed through absorption, distribution, metabolism, elimination, and toxicity studies, and the promising hits were docked into the binding site of the enzyme. 13-(4-Chlorobenzoyl)-10-hydroxy-14-methyl-8,13,13 b,14-tetrahydroindolo[2′,3′:3,4]pyrido[2,1- b]-quinazolin-5(7 H)-one (29) interacted favorably with the enzyme; it showed high similarity to MPI5. Molecular dynamic simulations for 29 proved the stability of its binding to SARS-CoV-2 protease over 100 ns; subsequent MMGBSA analysis also supported this principle. Furthermore, 29 elucidated higher limiting action on enzymatic behavior throughout the whole process when compared to MPI5. This provides sufficient evidence for the potential of evodiamine compounds in modern antiviral research, especially compound 29, against the modern COVID-19 pandemic.

Peanut, the only cash crop of rainfed areas of Pakistan, is facing immense challenges due to global warming. Climatic factors particularly the temperature fluctuations and rain pattern shift significantly impact the production and yield of peanut and unavailability of resilient varieties exacerbate this impact. To deal with the cropping pattern change and yield losses, due to climate vagaries, a study was conducted to develop early maturing hybrids using line into tester mating design. The F

Background:Brain natriuretic peptide (BNP) is released from the ventricular myocardium as a reaction to volume expansion and pressure overload. Since the thyroid hormones stimulate the release of BNP, it can be used as an indicator of thyroid failure and also guiding in thyroid control .So; this study was designed to assess the value of measuring serum BNP as a marker for diagnosis and follow up of patients with subclinical and overt hyperthyroidism. Patients and Methods: This is a prospective cohort study for patients with hyperthyroidism. Patients have been enrolled from Endocrinology Outpatient Clinic at Zagazig University Hospitals in the period from December 2018 to October 2020.Results: patients were divided into two major groups, overt hyperthyroidism (group 1) and subclinical hyperthyroidism (group 2).In all cases BNP level over 100 ng/l .Median for BNP in group (1) 671.89 and the median BNP in group (2 ) 318.19 .We noticed a significant elevation of BNP levels in group (1) than group (2) ( p =

Circulating long non-coding RNAs (lncRNA) are dysregulated in several diseases, especially cancers, e.g. non-small-cell lung cancer (NSCLC). Of specific notice in this regard is growth arrest-specific 5 gene (lncRNA GAS5), which is principally recognised as a tumor suppressor gene in numerous cancers. Functionally, GAS5 is involved in arresting cellular growth and induction of apoptosis. We analysed plasma GAS5 expression by qRT-PCR in 100 patients with NSCLC before and after tumour resection surgery. We reported a downregulation of GAS5 expression in NSCLC tissue and plasma, which showed elevation after surgery. Downregulation of GAS5 was associated with poor prognosis of NSCLC patients.

Early detection of colorectal cancer (CRC) is the most important factor in deciding its prognosis, so the need to develop an accurate screening test is a must. P-element induced wimpy testis (PIWI) RNA-823 (piR-823) is one of the first piRNAs recognized to be linked to malignancy. We aimed to investigate the expression levels of piR-823 in both serum and tissues of colorectal cancer patients and the ability to use its serum level as a non-invasive diagnostic biomarker to detect colorectal cancer. We determined piR-823 expression levels in 84 serum samples of CRC patients, 75 serum samples of healthy controls, and biological specimens obtained from the 84 patients with colorectal cancer from both the tumor tissues and the normal neighboring tissues using quantitative real-time reverse transcriptase-PCR. We showed that piR-823 had significantly higher serum and tissue expression levels in CRC patients compared to the controls. We observed a significant positive correlation between piR-823 serum levels and the staging of CRC, with significantly higher levels exhibiting advanced stages of CRC (III and IV). This translates into poorer differentiation and lymph node metastasis. The receiver operating characteristic curve (ROC curve) test showed 83.3% sensitivity and 89.3% specificity at a cut-off value of &gt, 5.98-fold change, with an area under the curve of 0.933 (p &lt, 0.0001) concerning the ability of piR-823 in diagnosing patients with colorectal carcinoma. piR-823 expression is upregulated in colorectal cancer patients’ serum and tissues, and it can be used as a diagnostic noninvasive biomarker for CRC.

Background Coronavirus disease 2019 (COVID-19) pandemic is an international public health emergency with major disruptions and devastating health consequences resulting from the associated cytokine storm syndrome. The aim of our research was to assess the inflammatory biomarkers and risk factors associated with severity of (COVID-19) patients. Methods A cross-sectional study was conducted and included 150 Egyptian patients with COVID-19. Patients were classified into mild, moderate, and severe according to the clinical and CT chest findings. Blood samples were collected from patients for laboratory assessment of inflammatory biomarkers. Results Our results showed significant negative correlation between oxygen saturation percent and serum levels of inflammatory markers. The correlations were statistically significant with IL-6, CRP, ferritin, LDH, and D-dimer which can be used as sensitive biomarkers for assessment of the risk of severity of infection in COVID 19 patients. Conclusions The study revealed that the risk factors associated with severity of COVID 19 infection included older age, male gender, presence of underlying chronic disease, and increased levels of inflammatory biomarkers: CRP, LDH, ferritin, IL-6, and D-dimer.

Bisphenol A (BPA) leads to ROS production that considered the core of different inflammatory and chronic obstructive pulmonary diseases. As a natural antioxidant, lycopene plays a significant role in the prevention of many chronic diseases. This study aimed to investigate the possible protective role of lycopene against BPA-induced lung alterations using morphometric, histological, immunohistochemical and biochemical methods. Forty rats aged 3 months were divided into four groups (n=10): control group, lycopene group comprising rats that received lycopene by gavage (10 mg/kg /day) for 30 days, BPA group comprising rats that received BPA by gavage (50 mg/kg/day) for 30 days and lycopene + BPA group. On the 30th day, blood and lung tissue samples were collected for biochemical, histological and immunohistochemical studies. Morphometrical and statistical analyses were performed. The BPA group revealed significantly elevated IL-1B, IL-6, MDA and NO, and it showed significantly reduced IL-10, SOD, CAT and GSH when compared to the control and lycopene + BPA groups. Upon histopathological and immunohistochemical examination, lycopene supplementation improved the BPA-induced alveolar collapse, lymphocytic infiltration, extravasated RBCs and fibrosis. The lycopene + BPA group showed significantly reduced mean percentage of 8-OHdG immunopositive and mean area percentages of Bax and caspase 3 immunopositive cells and significantly reduced mean area percentage of Bcl2 immunopositive cells as compared with the BPA group. Lycopene is a protective agent against BPA-induced lung injury because of its anti-apoptotic, anti-inflammatory and antioxidant effects, as confirmed by biochemical and histological studies.

Aflatoxin (AF) contamination of food products is still a major health issue globally. Prior studies suggest that exposure to AFs during pregnancy has harmful fetal outcomes. This preliminary study was designed to assess serum AFB

BACKGROUND Breast cancer (BC) is one of the leading causes of cancer mortality in women. Glutathione S-transferase (GSTT1) is involved in activation of detoxification reactions and catalysis of chemicals conjugation with glutathione. GSTT1 genotype is a limiting factor for some environmental diseases. Epigenetic changes have an essential role in BC through inappropriate interaction between genomic and environmental risk factors. AIM This study was directed to explore the association of BC risk with GSTT1 genetic variations and its methylation status in Egyptian women. DESIGN AND METHODS This study included 100 healthy women as the control group and 100 patients were clinically and histologically diagnosed with breast cancer. All blood samples were used for genomic DNA extraction. GSTT1 genotyping was accomplished by multiplex PCR and methylation-specific PCR was used to analyze the GSTT1 promoter methylation status. RESULTS Breast cancer patients showed significant incidence of null GSTT1 in relation to controls (p = 0.004). GSTT1 gene promoter methylation status showed significant difference between hypermethylated and unmethylated patients when compared with healthy subjects (p = 0.005). GSTT1 promoter methylation status was not significantly associated with null genotype. There was no significant association between GSTT1-null genotypes and BC stage in cases with or without family history, but for promotor methylation, there was significant association with stage III and IV breast cancer disease. CONCLUSION GSTT1 null genetic variant and promoter hypermethylation in the GSTT region of the gene may be considered as critical risk factors for BC in Egyptian women.
