Acute myeloid leukemia (AML) is a hematological malignancy that contains hereditary subgroups. AML can arise as a result of a previous myeloid malignancy. AML's molecular pathogenesis is not yet complete. NADPH quinone dehydrogenase 1 (NQ01), which is linked to AML, is one of a few handfuls of genes that have a role in AML pathogenesis. The goal of this study was to look at the roles of C609T and C465T polymorphisms in the NQ01 gene in the development of AML in Saudis. In this experimental study, 100 AML patients and 100 healthy controls were chosen. For the C609T and C465T PCR products, restriction enzymes were utilized in this study. AML cases and controls were investigated for genotype and allele frequencies. The average age of AML patients and control subjects was 39.9 ± 12.06 years. AML patients were 61% male and 39% female, while controls were 54% male and 46% female. The C609T and C465T polymorphisms in the NQ01 gene were not linked with any of the genotypes (p > 0.05). According to the findings of this investigation, the C609T and C465T polymorphisms play no effect in AML patients in Saudi Arabia.

Background: Monkeypox viral infection is considered as global public health and a rare disease caused by Monkeypox virus (MPXV), which is caused by smallpox-like virus and it causes pustules all over the body. MPV is an emerging zoonotic infection with sporadic occurrence globally and multiple outbreaks have been reported in African regions. The story of MPXV has been started since 1970 in Democratic republic of Cargo. The high cases of MPXV was majorly detected in Congo Rain Forest region in Africa. Animal-human (Zoonotic) transmission occurred, although the individual infected animal was not recognized. Human-human transmission occurs and is difficult until bodily fluids or respiratory droplets are exchanged. If a specific individual uses an infected person's towels or bed sheets, infection may occur. Aim: The aim of this review is to document the methods of diagnosis, treatments (vaccines) and future role of MPXV in human population. Output: The diagnosis is confirmed mainly through clinical diagnosis and then laboratory diagnosis such as cell-culture, serological and Polymerase Chain Reaction tests. Presently, there is no vaccine for MPXV but the smallpox vaccine will protect. The old vaccine includes antivirals approved for use against Orthopoxvirus, such as tecovirimat, which can treat up to 85 % of MPXV in humans. MPXV is now considered as transmission virus which affects from human to humans. The fatality rate was documented to be 3–10 % in children and in adults it is very low. Conclusion: This review concludes MPXV is not as contagious as COVID-19 but proper measures should be taken as mentioned in this review to avoid MPXV. Presently, controlling MPXV presents unique challenges, and future prospective global studies in antivirals for this disease, as well as an MPXV vaccines, are recommended to eliminate this virus.

Objective: This study describes the development of a cost-effective and sensitive immunosensor for rapid detection of the dengue virus (DENV) antigen in human plasma. Methods: Screen-printed carbon electrodes (SPCEs) were used to fabricate the immunosensor by immobilizing the DENV antibodies to its surface using 1-ethyl-3-(3-dimethylamino propyl)carbodiimide hydrochloride/N-hydroxysulfosuccinimide (EDC/s-NHS) as linker. The detection of the antigen–antibody interaction was achieved by linear sweep voltammetry (LSV) using potentiostat instrument and a sensor connector. The developed method was validated as per the ICH guidelines for linearity, sensitivity and accuracy. Results: The developed immunosensors showed excellent sensitivities in detecting the DENV antigens in both phosphate buffer saline (PBS) maintained at pH 7.4 as well as diluted human plasma. The limit of detection (LOD) values obtained in PBS was 0.11 nM; whereas in human plasma, it was calculated to be 0.16 nM. Good linearity was obtained for both PBS and human plasma over a wide range of concentrations showing promising applications of the immunosensor in both qualitative and quantitative detection of dengue virus antigen. Also, the developed immunosensor was able to detect the dengue antigen in 5 min showing rapid detection. Conclusion: A sensitive, reliable and cost-effective biosensor was developed which was able to detect the dengue virus antigen selectively and rapidly.

Background: Chewing Khat (Catha edulis) releases cathine and cathinone, which may reduce appetite via an unknown mechanism. This study investigated the peripheral and central effects of fresh leaves and buds of Catha edulis water extract (CEWE) on appetite biomarkers, gene expression, and body weight, using in vivo, ex vivo, and in silico models. Methods: Rats of both sexes were orally administered CEWE at different doses and durations in three different experiments. Liquid chromatography-mass spectroscopy (LC-MS)-MS was used to detect cathinone and cathine in the murine blood. The effect of Khat on serotonin receptors was studied in isolated rat fundus samples. Docking of the two Khat ligands was performed on G (The 5-hydroxytryptamine-type 2C receptor (5-HT2C) in an agonist-bound active conformation) and H (5-HT2C in an antagonist-bound inactive conformation) proteins to determine which ligands are most likely to act as agonists or antagonists. Results: Significant differences (P < 0.05) in body weight were observed between the CEWE-treated groups and the controls over eight weeks. However, the plasma leptin and ghrelin levels did not change significantly (P > 0.05). The expression of the ghrelin and leptin genes was also unaffected, but the expression of the 5-hydroxytryptamine (5-HT) gene decreased (P < 0.05) with CEWE treatment. CEWE antagonizes 5-HT receptors in isolated rat fundus samples. Docking findings indicated that the khat ligands bound to 5-HT2C receptors. Cathine and cathinone levels in rat plasma were measured. Conclusion: Khat extract may suppress appetite by antagonizing the 5-HT receptors. Further research is required to understand its mechanism and potential applications. [ABSTRACT FROM AUTHOR]

Vaccination is a groundbreaking approach in preventing and controlling infectious diseases. However, the effectiveness of vaccines can be greatly enhanced by the inclusion of adjuvants, which are substances that potentiate and modulate the immune response. This review is based on extensive searches in reputable databases such as Web of Science, PubMed, EMBASE, Scopus, and Google Scholar. The goal of this review is to provide a thorough analysis of the advances in the field of adjuvant research, to trace the evolution, and to understand the effects of the various adjuvants. Historically, alum was the pioneer in the field of adjuvants because it was the first to be approved for use in humans. It served as the foundation for subsequent research and innovation in the field. As science progressed, research shifted to identifying and exploiting the potential of newer adjuvants. One important area of interest is nano formulations. These advanced adjuvants have special properties that can be tailored to enhance the immune response to vaccines. The transition from traditional alum-based adjuvants to nano formulations is indicative of the dynamism and potential of vaccine research. Innovations in adjuvant research, particularly the development of nano formulations, are a promising step toward improving vaccine efficacy and safety. These advances have the potential to redefine the boundaries of vaccination and potentially expand the range of diseases that can be addressed with this approach. There is an optimistic view of the future in which improved vaccine formulations will contribute significantly to improving global health outcomes.

Acute Myeloid leukemia (AML) is the most common leukemia among adult population which begins with the bone marrow, but it frequently spreads to the blood stream as well. One of the common polymorphisms in AML is A66G in Methionine Synthase Reductase (MTRR), which converts isoleucine into methionine residue in the protein chain, the methionine/homocysteine cycle is disrupted. Limited studies were documented between A66G polymorphism in MTRR gene with AML. This study aimed to investigate the A66G polymorphism in MTRR gene with AML patients in the Saudi population. Peripheral blood was collected from 100 AML patients and 100 controls and DNA was isolated. Using A66G primers, polymerase chain reaction was performed followed by restriction fragment length polymorphism analysis. The mean age of both cases and controls was found to be an average of 39 years. Allele (G vs A: OR-3.41 [95 %CI: 1.87–11.24; p = 0.0001) and genotype analysis (GG vs AA: OR-3.43 [95 %CI: 1.45–8.11]; p = 0.0004) has shown the association. In conclusion, A66G polymorphism has a strong genetic role in the AML patients in Saudi population.

A high increase witnessed in type II diabetes mellitus (T2DM) globally has increasingly posed a serious threat to global increases in liver cancer with the association between diabetes mellitus type II and the survival rate in liver cancer patients showing unstable findings. An increase in the development and progression of chronic liver disease from diabetes mellitus patients may be connected to cancer of the liver with several links such as Hepatitis B and C virus and heavy consumption of alcohol. The link between T2DM patients and liver cancer is centered on non-alcoholic fatty liver disease (NAFLD) which could be a serious threat globally if not clinically addressed. Several reports identified metformin treatment as linked to a lower risk of liver cancer prognosis while insulin treatment or sulphonylureas posed a serious threat. Mechanistically, the biological linkage between diabetes type II mellitus and liver cancer are still complex to understand with only the existence of a relationship between NAFLD and high level of energy intake and diabetes mellitus induces hepatic damage, increased liver weight thereby causes multiple pro-inflammatory cytokines that lead to the development of liver cancer. Therefore, this review gives an account of the pathophysiological importance of liver cancer position with T2DM, with the role of NAFLD as an important factor that bridges them.

Aim: To develop and characterize doxorubicin-loaded sodium selenite nanoparticles (SSNP-DOX) and their surface attachment with cetuximab (mAb-SSNP-DOX). Methods: SSNP-DOX was formulated by gelation and then conjugated with cetuximab to form mAb-SSNP-DOX. Characterization included DLS, SEM, TEM, DSC, Raman spectroscopy and XRD. In vitro, the kinetics of doxorubicin release and cytotoxicity in MCF-7 breast cancer cells were investigated. Results: The zeta potential for SSNP-DOX and mAb-SSNP-DOX was -14.4 ± 10.1 mV and -27.5 ± 7.28 mV, with particle sizes of 181.3 nm and 227.5 nm, respectively. The formulation intensity was 89.7% for SSNP-DOX and 100% for mAb-SSNP-DOX, with PDI values of 0.419 and 0.251, respectively. SEM and TEM showed that mAb-SSNP-DOX was smooth and spherical. The DSC analysis revealed exothermic peaks at 102.44°C for SSNP-DOX and 144.21°C for mAb-SSNP-DOX, along with endothermic peaks at 269.19°C and 241.6°C, respectively. Raman spectroscopy showed a higher intensity for mAb-SSNP-DOX. The XRD study showed different peaks for each formulation. Both followed zero order kinetics for doxorubicin release. Cytotoxicity studies showed significant effects and high apoptosis in MCF-7 cells for both formulations. Conclusion: The mAb-SSNP-DOX showed promising properties, more effective doxorubicin release and higher cytotoxicity against breast cancer cells compared with SSNP-DOX. Article highlights Breast cancer Breast cancer is a significant cause of morbidity and mortality worldwide and is characterized by high heterogeneity and treatment resistance. MCF-7 cells are a commonly used human breast cancer cell line in research and a model for studying the efficacy of therapeutic interventions. Nanoparticle drug delivery system Drug delivery systems in the form of nanoparticles improve drugs' therapeutic efficacy and stability while minimizing unwanted side effects by enabling precise delivery to cancer cells. Targeted nanoparticle drug delivery systems, such as those incorporating monoclonal antibodies, further improve treatment outcomes by selectively targeting cancer cells and causing less damage to healthy tissue. Targeted breast cancer treatment The study focused on developing injectable nanoparticle formulations, SSNP-DOX and mAb-SSNP-DOX, which effectively target MCF-7 breast cancer cells. Combining cetuximab, a monoclonal antibody targeting the epidermal growth factor receptor (EGFR), with SSNP-DOX improved the specificity and efficacy of the treatment. Characterization & physicochemical stability The nanoparticle formulations were comprehensively characterized using dynamic light scattering (DLS), differential scanning calorimetry (DSC), Raman spectroscopy, x-ray diffraction (XRD) and nuclear magnetic resonance spectroscopy (NMR). These techniques confirmed the formulations' stability and uniformity, ensuring their suitability for targeted drug delivery. In vitro performance & enhanced efficacy The release profiles of doxorubicin from SSNP-DOX and mAb-SSNP-DOX showed sustained drug release over a prolonged period. In vitro, cytotoxicity studies showed that both formulations effectively suppressed the growth of MCF-7 breast cancer cells. Of the two, mAb-SSNP-DOX was the superior formulation, performing better on all parameters tested. Target specificity & overcoming drug resistance mAb-SSNP-DOX showed increased specificity in targeting breast cancer cells due to cetuximab. This combination of nanoparticles with cetuximab represents a promising approach to overcoming drug resistance in the treatment of breast cancer, offering improved efficacy and targeting of breast cancer cells. Future directions Future research should focus on optimizing these formulations, investigating the underlying molecular mechanisms and conducting extensive in vivo studies to validate the therapeutic potential of mAb-SSNP-DOXstance and conducting extensive in vivo studies to validate these findings.

Introduction: Previous studies have identified several risk factors for acute coronary syndrome (ACS). This study was intended to examine the potential risk of ACS associated with khat and tobacco use. Methods: A case-control study of 344 people (172 cases and 172 controls) was conducted at Prince Mohammed Bin Nasser Hospital in Jazan, Saudi Arabia, from April to September 2019. The cases and controls were matched for age (±5 years) and gender. Data were analyzed using descriptive, inferential, and modeling analyses. We utilized the adjusted odds ratio (AOR) to express the results. Results: The prevalence of ever khat chewing among all study participants was 29.1%, significantly higher for the cases with ACS than for the control group (43.6% vs 14.5%, p<0.001). Cigarette smokers accounted for 33.4% of the study participants, and 22.1% were ACS cases, which is a significantly higher percentage than the control group. The prevalence of smokeless tobacco was 20.3% among ACS cases and 14.5% among controls, with no statistically significant differences (p>0.05). In the final model, tobacco use was more likely to be reported among cases with myocardial infarction (MI) (AOR=4.58; 95% CI: 1.01–4.73, p<0.05) as was khat chewing (AOR=3.4; 95% CI: 1.55–7.46, p<0.05), after controlling for other traditional risk factors. Conclusions: Khat chewing was reported more by those who reported ACS. ACS cases were more likely to be frequent khat users with chewing sessions of five or more days per week. Regular tobacco use was also reported in those who reported ACS, and this increases with the amount of tobacco used. Implementing early intervention strategies can help mitigate the impact of khat chewing and smoking on the development of ACS. [ABSTRACT FROM AUTHOR]

Arthrospira platensis (Ap) has several advantageous adaptive mechanisms including its efficient response to elevated oxidative stress (OS). This study intends to identify the antioxidant effect, in vitro and in vivo, of a novel peptide (GP13), Ap-derived cysteine-desulfurase (CDS) peptide, for antioxidant role and the associated mechanism(s) by which the GP13 elicits cytoprotection under elevated OS.Using bioinformatics tools, a short sequence of amino acids GP13 with a predicted antioxidant effect has been identified from the cysteine sulfurase domain of ApCDS between 243 and 616 amino acids. The synthesized GP13 peptide expressed significant antioxidant activity against free-radicals at various concentrations (10–80 µM), as established through the DPPH, ABTS, SARS, and HRS assays.Besides, GP13 demonstrated no cytotoxicity on Vero cells and human leucocytes. In H2O2-induced human leucocytes, the peptide exhibited maximum ROS scavenging activity at a concentration of 80 µM. Reduced apoptotic body formation was identified using Hoechst 33,342 staining in GP13-exposed Vero cells. In vivo results revealed that pre-treated zebrafish larvae with GP13 (10–80 µM) ameliorated the H2O2-induced oxidative damage. Further, GP13 inhibited the H2O2-induced caspase-3-dependent apoptotic response at 96 h post fertilized (hpf) zebrafish larvae.Together, results demonstrated that in GP13 treated (80 µM) zebrafish there was a reduction in the expression of lipid peroxidation level; and an increase in antioxidant-enzymes. Therefore, it is possible that GP13 peptide derived from ApCDS has in vitro and in vivo antioxidant activity and that GP13 should be further investigated for potential therapeutic utility in OS-mediated complications.

Background and Aim: Colorectal cancer stands as a frequently occurring fatal disease for several decades and the use of nanoparticles has long been explored in cancer treatments. Engineering the size and shape to attain an optimal efficacy of the nanoparticles and using a specific plant resource to enhance its compatibility to other healthy cell is a propitious approach. The present study investigates the anti-cancer activity of CuO NP synthesized from Aegle marmelos leaf extract against human colorectal cancer. Materials and Methods: The CuO NPs (Nanoparticles) exhibited promising characteristics with UV and SEM-EDAX, its photochemical constituents were analyzed with FTIR, and the geometry of the synthesized nano-particles was studied using Zeta potential and particle size analyzer. The cell viability was scrutinized via trypan blue assay and further toxicity was determined by cell morphology and several in vitro analyses where the MTT assay presented that the 25 µg/mL of CuO NPs as the IC50 concentration. RESULTS: The nuclear fragmentation was studied by DAPI staining which resulted in increased fluorescence of the treated cells indicating the robust effect of the CuO NPs and the mitochondrial damage was monitored through MMP analysis with declining fluorescence. The most vital aspect of understanding cancer pathogenesis is oxidative stress which was evaluated by ROS, NO, and LPO with favorable outcome. Conclusion: The cell viability and ROS assay coalesce to suggest that CuO NPs indeed induce apoptosis and it is evident that Biogenically synthesized CuO NPs contain anti-proliferative potential and promotes apoptosis.

Background: Ovarian cancer is a prominent contributor to cancer-related death among women residing in developed countries. The most of instances are discovered when the cancer has already developed, which results in dismal consequences. Surgery, chemotherapy, and radiation were the top priorities for first-line treatment in clinics. Traditional cancer treatments have a substantial risk of toxicity and cancer recurrence in females. Plant extracts can be utilized as an alternative to traditional chemotherapeutic drugs to solve these issues. According to recent research, plant extracts show anti-tumor, anti-cancer, and anti-proliferative effects on human tumor cell lines that have been cultivated, as well as an antiangiogenic impact. Aim: Eupatorin is a class of flavonoids isolated from various medicinal plants with various potent biological properties including anti-cancer, anti-inflammatory, and vasorelaxant actions. Materials and Methods: In the current investigation, the potential of Eupatorin as an anti-cancer agent for ovarian cancer was evaluated. In this study was determination of cytotoxicity using WST-1 assay, LDH release assay, and apoptotic cell death was detected through AO/EB dual staining, estimation of pro-apoptotic markers using ELISA method and in silico analysis. Results: The viability of PA-1 cells was reduced with an increased dosage of Eupatorin. The LDH level was increased with increased concentration of Eupatorin. The apoptosis markers levels were also increased when PA-1 cells were exposed to Eupatorin indicating apoptosis of cancer cells. The results showed that apoptosis was induced by Eupatorin in PA-1 cells by triggering the caspase pathway. In addition, the in silico experiment was done to examine the binding efficacy of Eupatorin with VEGF-A/VEGFR and found that Eupatorin can bind more persistently to VEGF-A/VEGFR than apratoxin thereby preventing angiogenesis. Conclusion: All these results suggest that Eupatorin can be used as a potent anti-cancer drug for ovarian cancer. [ABSTRACT FROM AUTHOR]

The Curcuma longa plant is endowed with multiple traditional and therapeutic utilities and is here explored for its phytochemical constituents and cytotoxic potential. Turmeric rhizomes were extracted from three different solvents and screened for the presence of different phytochemical constituents, observation of which indicated that the polar solvents favoured extraction of greater versatile phytochemical constituents. These extracts were investigated for their cytotoxic potential by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay on three different of cell lines including SCC-29B (oral cancer cell line), DU-145 (prostate cancer cell line) and the Vero cell line (healthy cell line/non-cancerous cell line). This assay was performed by taking three extracts from isolated curcuminoids and a pure bioactive compound bisdemethoxycurcumin (BD). Bisdemethoxycurcumin was isolated from curcuminoids and purified by column and thin-layer chromatography, and its structural characterisation was performed with different spectroscopic techniques such as FTIR, NMR (1H Proton and 13C Carbon-NMR) and LC-MS. Amongst the extracts, the ethanolic extracts exhibited stronger cytotoxic potential against the oral cancer cell line (SCC-29B) with an IC50value of 11.27 μg/mL, and that this was too low of a cytotoxicity against the Vero cell line. Although, curcuminoids have also shown a comparable cytotoxic potential against SCC-29B (IC50 value 16.79 μg/mL), it was not as potent against the ethanolic extract, and it was even found to be cytotoxic against healthy cell lines at a very low dose. While considering the isolated compound, bisdemethoxycurcumin, it also possessed a cytotoxic potential against the prostate cancer cell line (DU-145) (IC50 value of 93.28 μg/mL), but was quite safe for the healthy cell line in comparison to doxorubicin.
