Studying Human Pathogenic Cryptococcus Gattii Lineages by Utilizing Simple Sequence Repeats to Create Diagnostic Markers and Analyzing Diversity.

In this study, we compared the occurrence, relative abundance (RA), and density (RD) of simple sequence repeats (SSRs) among the lineages of human pathogenic Cryptococcus gattii using an in-silico approach to gain a deeper understanding of the structure and evolution of their genomes. C. gattii isolate MF34 showed the highest RA and RD of SSRs in both the genomic and transcriptomic sequences, followed by isolate WM276. In both the genomic (50%) and transcriptomic (65%) sequences, trinucleotide SSRs were the most common SSR class. A motif conservation study found that the isolates had stronger conservation (56.1%) of motifs, with isolate IND107 having the most (5.7%) unique motifs. We discovered the presence of SSRs in genes that are directly or indirectly associated with disease using gene enrichment analysis. Isolate-specific unique motifs identified in this study could be utilized as molecular probes for isolate identification. To improve genetic resources among C. gattii isolates, 6499 primers were developed. These genomic resources developed in this study could help with diversity analysis and the development of isolate-specific markers.

Novel Insights in the Hypertension Treatment & Type 2 Diabetics Induced by Angiotensin Receptor Blockers: MD Simulation Studies & Molecular Docking of Some Promising Natural Therapies.

Angiotensin receptor blockers (ARBs) are commonly used to treat hypertension that target the hormonal system (renin-angiotensin system (RAS)), which regulates various physiological functions in the body. ARBs work by blocking the binding of angiotensin II to its receptor, thereby preventing a rise in blood pressure. These drugs not only normalize the overactivation of RAS but also provide protective effects against cardiovascular, renal, and type 2 diabetic patients. Inappropriate RAS activity has been linked to insulin resistance of type 2 diabetes. Olmesartan, as an ARB, was found to have a beneficial role in reducing postprandial glucose levels in type 2 diabetes. However, ARBs can cause side effects, prompting a search for new compounds that have fewer adverse effects. This study explores the potential of natural metabolites, specifically eugenol, gallic acid, myricetin, p-cymene, quercetin, and kaempferol, as ARB inhibitors compared to the current standard, olmesartan. Using in silico studies, the binding affinity of these natural substances to the ARB receptor was evaluated. The results showed that myricetin and kaempferol had affinities higher than those of olmesartan, suggesting that they could serve as promising ARB inhibitors for hypertension treatment. These natural compounds could provide an alternative approach to conventional antihypertensive drugs, which may have fewer side effects. However, more research is needed to validate the efficacy and safety of these natural compounds as antihypertensive drugs. Further in vitro and in vivo studies are needed to confirm their effectiveness and safety. This study provides a promising starting point for future investigations into the potential of natural metabolites as alternative treatments for hypertension. The findings also highlight the importance of exploring natural alternative treatments for hypertension and the protective effects of ARBs on early stage type-2 diabetics.

The Rapidly Changing Patterns in Bacterial Co-Infections Reveal Peaks in Limited Gram Negatives during COVID-19 and Their Sharp Drop Post-Vaccination, Implying Potential Evolution of Co-Protection during Vaccine-Virus-Bacterial Interplay.

SARS-CoV-2 has caused the most devastating pandemic of all time in recent human history. However, there is a serious paucity of high-quality data on aggravating factors and mechanisms of co-infection. This study aimed to identify the trending patterns of bacterial co-infections and types and associated outcomes in three phases of the pandemic. Using quality hospital data, we have investigated the SARS-CoV-2 fatality rates, profiles, and types of bacterial co-infections before, during, and after COVID-19 vaccination. Out of 389 isolates used in different aspects, 298 were examined before and during the pandemic (n = 149 before, n = 149 during). In this group, death rates were 32% during compared to only 7.4% before the pandemic with significant association (p-value = 0.000000075). However, the death rate was 34% in co-infected (n = 170) compared to non-co-infected patients (n = 128), indicating a highly significant value (p-value = 0.00000000000088). However, analysis of patients without other serious respiratory problems (n = 28) indicated that among the remaining 270 patients, death occurred in 30% of co-infected patients (n = 150) and only 0.8% of non-co-infected (n = 120) with a high significant p-value = 0.00000000076. The trending patterns of co-infections before, during, and after vaccination showed a significant decline in Staphylococcus aureus with concomitant peaks in Gram negatives n = 149 before/n = 149 during, including Klebsiella pneumonian = 11/49 before/during, E. coli n = 10/24, A. baumannii n = 8/25, Ps. aeruginosa n = 5/16, and S. aureus 13/1. Nevertheless, in the post-vaccination phase (n = 91), gender-specific co-infections were examined for potential differences in susceptibility. Methicillin-resistant S. aureus dominated both genders followed by E. coli in males and females, with the latter gender showing higher rates of isolations in both species. Klebsiella pneumoniae declined to third place in male patients. The drastic decline in K. pneumoniae and Gram negatives post-vaccination strongly implied a potential co-protection in vaccines. Future analysis would gain more insights into molecular mimicry.

Distribution and conservation of simple sequence repeats in plant pathogenic species of Zymoseptoria and development of genomic resources for its orphaned species.

To better understand the structure and evolution of the genomes of four plant pathogenic species of Zymoseptoria, we analyzed the occurrence, relative abundance (RA), and density (RD) of simple sequence repeats (SSRs) in their whole genome and transcriptome sequences. In this study, SSRs are defined as repeats of more than 12 bases in length. The genome and transcriptome sequences of Zymoseptoria ardabiliae show the highest RA (201.1 and 129.9) and RD (3229.4 and 1928.2) of SSRs, while those of Zymoseptoria pseudotritici show the lowest RA (167.2 and 118.5) and RD (2482.2 and 1687.0). The majority of SSRs in the genomic and transcriptome sequences of species were trinucleotide SSRs, while dinucleotide SSRs were the least common. The most common trinucleotide motifs in the transcriptomic sequences across all species were those that encoded the amino acid arginine. As per our motif conservation study, Zymoseptoria tritici (12.4%) possessed the most unique motifs, while Z. pseudotritici (3.9%) had the fewest. Overall, only 38.1% of the motifs were found to be conserved among the species. Gene enrichment studies reveal that three of the species, Z. ardabiliae, Zymoseptoria brevis, and Z. pseudotritici, have SSRs in their genes related to cellular metabolism, while the remaining Z. tritici harbors SSRs in genes related to DNA synthesis and gene expression. In an effort to improve the genetic resources for the orphan species of pathogenic Zymoseptoria, a total of 73,134 primers were created. The genomic resources developed in this study could help with analyses of genetic relatedness within the population and the development of species-specific markers.

Biostimulation of green microalgae Chlorella sorokiniana using nanoparticles of MgO, Ca10(PO4)6(OH)2, and ZnO for increasing biodiesel production.

Microalgae have the potential to become the primary source of biodiesel, catering to a wide range of essential applications such as transportation. This would allow for a significant reduction in dependence on conventional petroleum diesel. This study investigates the effect of biostimulation techniques utilizing nanoparticles of Magnesium oxide MgO, Calcium hydroxyapatite Ca10(PO4)6(OH)2, and Zinc oxide ZnO to enhance the biodiesel production of Chlorella sorokiniana. By enhancing cell activity, these nanoparticles have demonstrated the ability to improve oil production and subsequently increase biodiesel production. Experimentally, each nanomaterial was introduced at a concentration of 15 mg L-1. The results have shown that MgO nanoparticles yielded the highest biodiesel production, with a recorded yield of 61.5 mg L-1. Hydroxyapatite nanoparticles, on the other hand, facilitated lipid accumulation. ZnO nanoparticles showcased a multifaceted advantage by enhancing both growth and lipid content. Thus, it is suggested that these nanoparticles can be used effectively to increase the lipid content of microalgae. These findings highlight the potential of biostimulation strategies utilizing MgO, hydroxyapatite, and zinc oxide nanoparticles to bolster biodiesel production.

Tinea Unguium and Tinea Pedis and Their Correlation With Diabetes Mellitus in the General Population in the Hail Region, Saudi Arabia: A Cross-Sectional Study.

Background Tinea pedis or foot ringworm is an infection of the feet affecting the soles, interdigital clefts of toes, and nails, with a dermatophyte fungus. It is also called athlete's foot. Onychomycosis of the nail is caused by dermatophytes called Tinea unguium. An abnormal nail not caused by a fungal infection is a type of dystrophic nail. Onychomycosis can infect both fingernails and toenails, but onychomycosis of the toenail is much more prevalent. Aim The study aimed to assess the knowledge, perception, and awareness among a sample from Ha'il City, Saudi Arabia, of the definitions, risk factors, symptoms, diagnosis, complications, and treatment of both Tinea pedis and Tinea unguium, along withtheir correlation with diabetic patients. Material A cross-sectional survey was distributed throughout Ha'il City. An online questionnaire was designed and distributed via various social media apps, which included questions concerning participants' sociodemographic information, alongside questions regarding the risk factors, signs, symptoms, complications, and management of both Tinea pedis and Tinea unguium. Methods SPSS for Windows v22.0 (IBM Corp. Released 2013. IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY: IBM Corp.) was used for statistical analysis. Results The overall awareness of the study's participants about Tinea Pedis and Tinea unguium infection was low (34.82%).

The Extent of the Use of Multivitamins and Multimineral Supplements Without Clinically Measurable Benefits Among Adults in Ha'il, Saudi Arabia: A Cross-Sectional Study.

Introduction Multivitamins and multiminerals (MVMM) are nutritional supplements that contain a wide range of important nutrients. The use of vitamins and minerals has been showing a tremendous increase over the past few years due to the high demand for supplements to replenish nutritional deficiencies. Purpose This study aimed to assess MVMM usage, the reasons why people chose to use MVMM, and the factors related to this usage. Methodology A cross-sectional study was conducted on adults living in Ha'il, Saudi Arabia. Data were collected between October 31 and December 14, 2022, a self-administered online questionnaire was used, and data were analyzed using SPSS version 25.0 (IBM Corp, Armonk, NY). Results A total of 310 participants enrolled in the study, of which 240 (77.42%) were females and 70 (22.58%) were males. The extent of the use of MVMM supplements without clinically measurable benefits was more than half of the present study participants (58.71%). There was a significant difference between MVMM use and gender or employment status. MVMM usage on a regular basis was found to be associated with satisfaction with the outcomes. The majority of participants used MVMM to promote health. Calcium and vitamin D were found to be the most common types of dietary supplements used. Conclusion The use of MVMM supplements without clinically measurable benefits was more prevalent among females. It is important to promote public health awareness programs about the benefits and risks of overdose.

Human beta-defensin 1 circulating level and gene polymorphism in non-segmental vitiligo Egyptian patients.

BACKGROUND: Vitiligo is an acquired depigmented skin disorder. It has a genetic and autoimmune background. Human beta defensin-1(HBD-1) plus its gene polymorphism were linked to some autoimmune disorders. OBJECTIVE: To elucidate the possible role of HBD-1 in the pathogenesis of non-segmental vitiligo (NSV) through evaluation of HBD-1 serum levels and its single nucleotide polymorphism (SNP) in patients having NSV, in addition, to correlating the results with the extent of vitiligo in those patients. METHODS: A current case-control study included 50 patients having NSV and 50 controls. The authors used Vitiligo Area Scoring Index (VASI) score to assess vitiligo severity and laboratory investigations to assess serum HBD-1 level using ELISA and defensin-beta1 (DEFB1) SNP using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS: There were significantly lower HBD-1 serum levels in NSV cases than in controls (p < 0.001). There was a significant predominance of GG DEFB1 genotype and G allele in NSV patients in comparison to controls (p < 0.001). The levels of serum HBD-1 and DEFB1 genotypes were not associated or correlated significantly with any of the personal and clinical parameters of vitiligo patients. STUDY LIMITATION: The small sample size. CONCLUSIONS: DEFB1 gene polymorphism (GG genotype and G allele) may modulate vitiligo risk and contribute to vitiligo development in Egyptian populations. Decreased circulating HBD-1 levels might have an active role in vitiligo etiopathogenesis that could be mediated through its possible anti-inflammatory effects.

Correlation between the severity of COVID-19 vaccine-related adverse events and the blood group of the vaccinees in Saudi Arabia: A web-based survey.

Background: Recent epidemiological studies have reported an association between the ABO blood group and the acquisition, symptom severity, and mortality rate of coronavirus disease 2019 (COVID-19). However, the association between the ABO blood group antigens and the type and severity of COVID-19 vaccine-related adverse reactions has not been elucidated. Patients and Methods: We conducted a cross-sectional, questionnaire-based study in Saudi Arabia from February to April 2022. The study cohort included adults who had received or were willing to receive at least two doses of a COVID-19 vaccine of any type. We used Chi-square test to assess the association between the ABO blood groups and vaccine-related adverse reactions. p values of <0.05 were considered significant. Results: Of the 1180 participants, approximately half were aged 18-30 years old, 69.2% were female, and 41.6% reported their blood group as O. The most frequent COVID-19 vaccine-related adverse reactions were fatigue (65%), pain at the injection site (56%), and headache (45.9%). These adverse reactions demonstrated significant correlations with the education level (p = 0.003) and nationality (p = 0.018) of the participants following the first dose, with gender (p < 0.001) following the second dose, and with the general health status (p < 0.001) after all the doses. Remarkably, no correlation was observed between the severity of the vaccine-related adverse reactions and ABO blood groups. Conclusion: Our findings do not support a correlation between the severity of COVID-19 vaccine-related adverse reactions and the ABO blood groups of the vaccinees. The creation of a national database is necessary to account for population differences.

Exploring the effect of Jasmonic Acid for Aphids control for improving the yield of Triticum aestivum varieties.

Many biotic and abiotic factors influence the production of wheat (Triticum aestivum L.). Among biological agents, aphids are destructive pests effecting wheat yield drastically. This study was designed to evaluate the impact of foliar Jasmonic acid spray on aphid population as well as on plant growth during aphid infestation in two wheat varieties i.e., Borlaug-2015 and Zincol-2015. Plants are cultivated in pots and treated with jasmonic acid at concentrations of 0.1 and 1 mM (JA). The results revealed that length of shoot and roots decreased after aphid stress and was improved (21-24%) by JA spray. Photosynthetic pigments increased after applying the jasmonic acid spray compared to control plants. Jasmonic acid spray helped the plants to recover from aphid stress by enhanced production of antioxidant enzymes CAT (Catalase) (65-71%), SOD (Superoxide dismutase) (71-74%) and POD (Peroxidase) (61-65%). Consequent to improved defence system, plants treated with JA had fewer aphids as compared to control (60-73% reduction), 24 h after spray. The higher concentration of JA (1 mM) proved more effective as compared to 0.1 mM jasmonic acid. Moreover, Zincol-2015 appeared tolerant as compared to Borlaug-2015 against aphid infestation. The application of jasmonic acid as an exogenous foliar application showed an overall positive impact on the physiological and biochemical attributes of both varieties. It helps the plants to enhance resistance against the biotic stress and can be adopted as future alternative for aphid management. However, detailed studies regarding understanding of underlying molecular mechanisms are needed to optimize the mode for field application.

Persistence of COVID-19 symptoms beyond 3 months and the delayed return to the usual state of health in Saudi Arabia: A cross-sectional study.

A substantial number of COVID-19 survivors describe ongoing symptoms long after the acute phase. This so-called post-COVID-19 syndrome or long COVID occurs irrespective of initial disease severity. Objectives: This cross-sectional study aims to describe and characterise the prevalence of persistent COVID-19 symptoms beyond three months and to evaluate the risk factors for the delayed return to the usual state of health. Methods: An electronic survey was developed, piloted, and conducted during the first wave of the COVID-19 pandemic. The survey consisted of questions exploring socio-demographic data, comorbidities, COVID-19 disease (diagnosis, presenting symptoms, management, and persistent symptoms), and the return to the usual state of health. Participants were users of social media platforms. We received results from 746 respondents. One hundred thirty-six responses were excluded due to a self-diagnosis of COVID-19. Respondents reporting a COVID-19 diagnosis 3 months or more prior to the study (N = 213) were included in the analysis. Predictors of the delayed return to the usual state of health were identified by logistic regression. Results: Three months or more after a COVID-19 diagnosis, almost half of the respondents, 109 (51.2%), had residual symptoms. The five most prevalent persistent symptoms were fatigue (13.6%), altered sense of smell (12.7%), muscle aches (10.3%), headache (9.9%), and body aches (8.5%). When questioned regarding the return to baseline health, 152 (71.4%) answered in the affirmative. The total number of chronic medical conditions was determined as a statistically significant predictor for the delayed return to the usual state of health. Conclusion: Three months or more after acute COVID-19 infection, 5 out of 10 survivors experienced persistent symptoms, and 3 out of 10 reported a delayed return to baseline health. Considering the overall burden of COVID-19 disease, this can pose health and socio-economic challenges. Therefore, health systems need support in managing long COVID and improving long-term COVID-19 outcomes.

MD Simulation Studies for Selective Phytochemicals as Potential Inhibitors against Major Biological Targets of Diabetic Nephropathy.

Diabetes is emerging as an epidemic and is becoming a public health concern worldwide. Diabetic nephropathy is one of the serious complications of diabetes, and about 40% of individuals with diabetes develop diabetic nephropathy. The consistent feature of diabetes and its associated nephropathy is hyperglycemia, and in some cases, hyperamylinemia. Currently, the treatment includes the use of medication for blood pressure control, sugar control, and cholesterol control, and in the later stage requires dialysis and kidney transplantation, making the management of this complication very difficult. Bioactive compounds, herbal medicines, and extracts are extensively used in the treatment and prevention of several diseases, and some are reported to be efficacious in diabetes too. Therefore, in this study, we tried to identify the therapeutic potential of phytochemicals used in in silico docking and molecular dynamic simulation studies using a library of 5284 phytochemicals against the two potential targets of type 2 diabetes-associated nephropathy. We identified two phytochemicals (i.e., gentisic acid and michelalbine) that target human amylin peptide and dipeptidyl peptidase-4, respectively, with good binding affinity. These phytochemicals can be further evaluated using in vitro and in vivo studies for their anti-hyperglycemia and anti-hyperamylinemia effects.

Identifying the alpha-glucosidase inhibitory potential of dietary phytochemicals against diabetes mellitus type 2 via molecular interactions and dynamics simulation.

The research aims to identify the inhibitory potential of natural dietary phytochemicals against non-insulinotropic target protein alpha-glucosidase and its possible implications to diabetes mellitus type 2. A data set of sixteen plant-derived dietary molecules viz., 4,5-dimethyl-3-hydroxy-2(5H)-furanone, apigenin, bromelain, caffeic acid, cholecalciferol, dihydrokaempferol 7-o-glucopyranoside, galactomannan, genkwanin, isoimperatorin, luteolin, luteolin 7-o-glucoside, neohesperidin, oleanoic acid, pelargonidin-3-rutinoside, quercetin, and quinic acid were taken to accomplish molecular docking succeeded by their comparison with known inhibitors including acarbose, miglitol, voglibose, emiglitate, and 1-deoxynojirimycin. Among all phyto-compounds, bromelain (ΔG: -9.54 kcal/mol), cholecalciferol (-8.47 kcal/mol), luteolin (-9.02 kcal/mol), and neohesperidin (-8.53 kcal/mol) demonstrated better binding interactions with alpha-glucosidase in comparison to the best-known inhibitor, acarbose (ΔG: -7.93 kcal/mol). Molecular dynamics simulation of 10 ns duration, CYP450 site of metabolism identification, and prediction of activity spectra for substances depicted the bromelain as the most stable inhibitor compared to luteolin and acarbose. Findings of molecular interactions, molecular dynamics study, metabolism, and biological activity prediction proved bromelain as a potential alpha-glucosidase inhibitor. Thus, bromelain might be helpful as an insulin-independent therapeutic molecule towards controlling and managing diabetes mellitus type 2.

In vitro and in vivo study of inhibitory potentials of α-glucosidase and acetylcholinesterase and biochemical profiling of M. charantia in alloxan-induced diabetic rat models.

OBJECTIVES: Diabetes mellitus is a multifactorial chronic disease that affects the human population and it is the third most common cause of death worldwide. Momordica charantia is used as popular folk medicine and its action against diabetes mellitus remains unclear. We investigated the inhibitory potentials of α-glucosidase, acetylcholinesterase, and biochemical profiling of M. charantia in alloxan-induced diabetic rat models. METHODS: An In vivo study was carried out by using twenty male albino Wistar rats randomly divided into five groups each comprising four rats. Diabetes mellitus was induced by single intraperitoneal administration of 80 mg/kg body weight of alloxan and treatment with plant extract was conducted for a period of thirty days to check their impact on body weight and differentblood values. Biochemical profiling and characterization were performed by in vitro assays and HPLC, and FTIR. Histopathologic effects of M. charantia were examined through automated image analysis. Results were analyzed through Tukey's test, a complete randomized design and two factorial designs under CRD. RESULTS: Methanolic extract demonstrated potent alpha-glucosidase (72.30 ± 1.17%) and acetylcholinesterase (50.12 ± 0.82%) inhibitory activities. HPLC analysis confirmed the existence of vital flavonoids, antioxidants, and saponins. FTIR revealed the presence of hydroxyl groups, esters, alkanes, alkenes, alkynes, ketones, alcohols, amines and carboxylic acids as major functional groups. Results of in vivo study demonstrated that co-administration of alloxan and methanolic extract of M. charantia significantly improved the levels of fasting blood glucose, glycated hemoglobin and insulin in diabetic rats. CONCLUSION: M. charantia can be recommended as a therapeutic adjunct for diabetic patients as it can provide favorable remedial action in the context of the diabetes continuum of metabolic syndrome.

Role of MicroRNA-31 (miR-31) in Breast Carcinoma Diagnosis and Prognosis.

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.

Incidence of Epstein-Barr Virus Among Women With Breast Cancer Using Monoclonal Antibodies for Latent Membrane Protein 1 (LMP1).

BACKGROUND/AIM: Breast cancer is a common type of cancer in Sudan. Numerous studies propose viral oncogenesis as an etiological factor for breast cancer. The aim of the study was to analyze the presence of the Epstein-Barr virus (EBV) using monoclonal antibodies against latent membrane protein 1 (LAMP1) and determine the correlation between the presence of EBV and clinicopathological characteristics. PATIENTS AND METHODS: This study used immunohistochemistry to analyze the presence of EBV in 202 samples from Sudanese women diagnosed with breast cancer. Clinicopathological data were collected from patient records from the Radiation and Isotopes Centre in Khartoum State, Republic of Sudan. RESULTS: This study included 202 patients 168 (83.2%), 16 (7.9%), and 18 (8.9%), diagnosed with invasive ductal carcinoma, invasive lobular carcinoma, and papillary carcinoma, respectively. Axillary lymph node metastasis was present in 57 (28.2%) of cases, while 11 patients (5.4%) tested positive for EBV. The mean age of patients was 48.14±14.4 years. EBV infection was more frequently detected in invasive ductal carcinoma cases, and EBV positivity was not associated with cancer type, grade, progesterone levels, and HER2 expression. On the other hand, a statistically significant association was found between EBV presence and lymph node involvement, estrogen receptor status, and age group. CONCLUSION: EBV may not play a vital role in the pathogenesis of breast carcinoma in Sudanese women.

Value of Serum miRNA-96-5p and miRNA-99a-5p as Diagnostic Biomarkers for Hepatocellular Carcinoma.

Purpose: Circulatory microRNAs (miRNAs) have the potential to be employed as markers for cancer detection and as prognostic tools for disease management. 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.

Therapeutic Potential of Selected Medicinal Plant Extracts against Multi-Drug Resistant Salmonella enterica serovar Typhi.

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.
