A healthy balanced diet and a healthy lifestyle are very closely linked.Whichever the biological link is,it is overwhelming to understand.Modifications in how food is served,divided up,and supervised,such as the introduction of nutritional hygiene standards,food handling practices,and the entry of macro and micronutrients,have had a big impact on human health in the last few decades.Growing evidence indicates that our gut microbiota may affect our health in ways that are at least in part influenced by our diet and the ingredients used in the preparation of our food and drinks,as well as other factors.As a new problem,this one is getting a lot of attention,but it would be hard to figure out how the gut microbiota and nutrition molecules work together and how they work in certain situations.Genetic analysis,metagenomic characterization,configuration analysis of foodstuffs,and the shift to digital health information have provided massive amounts of data that might be useful in tackling this problem.Machine learning and deep learning methods will be employed extensively as part of this research in order to blend complicated data frames and extract crucial information that will be capable of exposing and grasping the incredibly delicate links that prevail between diet,gut microbiome,and overall wellbeing.Nutrition,well-being,and gut microorganisms are a few subjects covered in this field.It takes into account not only databases and high-speed technology,but also virtual machine problem-solving skills,intangible assets,and laws.This is how it works:Computer vision,data mining,and analytics are all discussed extensively in this study piece.We also point out limitations in existing methodologies and new situations that discovered in the context of current scientific knowledge in the decades to come.We also provide background on"bioinformatics"algorithms;recent developments may seem to herald a revolution in clinical research,pushing traditional techniques to the sidelines.Furthermore,their true potential rests in their ability to work in conjunction with,rather than as a substitute for,traditional research hypotheses and procedures.When new metadata propositions are made by focusing on easily understandable frameworks,they will always need to be rigorously validated and brought into question.Because of the huge datasets available,assumption analysis may be used to complement rather than a substitute for more conventional concept-driven scientific investigation.It is only by employing all of us that we will all increase the quality of evidence-based practice. 展开更多

Aim: To detect the expression of hepatitis B virus (HBV) genes (HB S and C genes) in early embryonic cells after introducing motile human sperm carrying HBV DNA into zona-free hamster oocytes via the in vitro fertilization (IVF) technique. Methods: Human sperm-mediated HBV genes were delivered into zona-free hamster oocytes by the IVF method. Polymerase chain reaction (PCR) was used to detect HB S and pre-Core/Core (pre-C/C) coding genes both in one- and two-cell embryos. Reverse transcription-PCR (RT-PCR) analysis was used to study the expression of the two genes. Fluorescence in situ hybridization (FISH) analysis using the full-length HBV DNA as the hybridization probe was performed to confirm the integration of viral DNA in the host embryonic genome. Results: Both HB S and pre-C/C coding genes are present and transcribed in one- and two-cell embryos originated from hamster ova IVF with human spermatozoa carrying HBV DNA sequences. Conclusion: Sperm-mediated HBV genes are able to replicate and express themselves in early embryonic cells. These results provide direct evidence that HBV DNA could transmit vertically to the next generation via the male germ line. 展开更多

Tumor necrosis factor-alpha (TNF-α) is an important cytokine in generating an immune response against infection with hepatitis C virus (HCV). The functions of TNF-α may be altered by single-nucleotide polymorphisms (SNPs) in its gene structure. We hypothesized that SNPs in TNF-α may be important in determining the outcome of an HCV infection. To test this hypothesis, we investigated the role of the polymorphism -308G/A, which is located in the promoter region of the TNF-α gene, in the progression of HCV infection in Egyptian patients using a quantitative real-time polymerase chain reaction (qRT-PCR). The distribution of this polymorphism and its impact on the serum level of TNF-α was compared between 90 HCV-infected patients [45 with HCV-induced cirrhosis and 45 with HCV-related hepatocellular carcinoma (HCC)] and 45 healthy Egyptian volunteers without any history of liver disease. Our results showed that at the TNF-α -308 position, the G/G allele was most common (78.5% ) in the study population, with the G/A and A/A alleles occurring less frequently (13.3% and 8.1% , respectively). Frequencies of G/G, G/A, and A/A genotypes were 87%, 7%, and 6% in patients with liver cirrhosis and were 94% , 4% , and 2% in patients with HCC, respectively. Serum levels of TNF-α were significantly higher in HCV-infected patients than in healthy controls, indicating that the TNF-α -308 polymorphism does not influence the production of TNF-α. The serum level of TNF-α was positively correlated with HCV infection. Taken together, these findings suggest that the TNF-α -308 polymorphism may not be a host genetic factor associated with the severity of HCV infection, but may be an independent risk factor for HCC. 展开更多

AIM: We designed two synthetic-core-specific peptides core 1 (C1) and core 2 (C2), and an E1-specific peptide (E1). We produced specific polyclonal antibodies againstthese peptides and used the antibodies for detection of HCV antigens on surface and within infected peripheral blood leukocytes.METHODS: Peripheral blood from a healthy individual who tested negative for HCV RNA was incubated with HCV type 4 infected serum for 1 h and 24 h at 37 ℃. Cells were stained by direct and indirect immunofluorescence and measured by flow cytometry.RESULTS: After 1 h of incubation, antibodies against C1,C2, and E1 detected HCV antigens on the surface of 27%,26% and 73% of monocytes respectively, while 10%, 5% and 9% of lymphocytes were positive with anti-C1, anti-C2 and anti-E1 respectively. Only 1-3% of granulocytes showed positive staining with anti-C1, anti-C2 and anti E1 antibodies. After 24 h of incubation, we found no surface staining with anti-C1, anti-C2 or anti-E1. Direct immunostaining using anti-C2 could not detect intracellular HCV antigens, after 1 h of incubation with the virus, while after 24 h of incubation, 28% of infected cells showed positive staining. Only plus strand RNA was detectable intracellularly as early as 1 h after incubation, and remained detectable throughout 48 h post-infection.Interestingly, minus RNA strand could not be detected after 1 h, but became strongly detectable intracellularly after 24 h post-infection.CONCLUSION: Monocytes and lymphocytes are the preferred target cells for HCV infection in peripheral blood leukocytes. Our specific anti-core and anti-E1 antibodies are valuable reagents for demonstration of HCV cell cycle.Also, HCV is capable of infecting and replicating in peripheral blood mononuclear cells as confirmed by detection of minus strand HCV RNA as well as intracellular staining of core HCV antigen. 展开更多

The present research reports of quick and marked changes induced by plant extract of Euryops arabicus in the gene expression of 49-kDa apyrases,cytoskeletal proteins,ATPases,ADPase and amount of amino acid of pea(Pisum sativum L.var.Alaska).Pellets of cytoskeletals proteins(27000 xg)were probed with anti-apyrase antibody,biotinylated anti-rat,actin and alpha and beta-tubulin for Western blotting.ATPase and ADPase activities were determined based on the hydrolytic efficacy of adenine triphosphate and adenine diphosphate.By 72 hours,the abundance of apyrases,cytoskeletal proteins and amount of amino acid in pellets of 27000 xg of germinated pea seeds in E.arabicus extracts were sharply increased than those sown in distilled water.All the samples exhibited that the stems had more amount from apyrases,cytoskeletal proteins,amino acids and ATPase and ADPase activities than primary leaves and primary roots that were germinated either on E.arabicus water extract or in distilled water.Based on the enzyme’s capability to hydrolyse nucleotide triphosphate and nucleotide diphosphate as well as the direct association between expression of 49-kDa apyrase and cytoskeletal proteins,E.arabicus water extract had an important effect on plant germinations. 展开更多

Transforming growth factor-β?(TGF-β) superfamily is a key player in the regulation of a wide variety of physiological processes from development to pathogenesis. Since the discovery of the prototypic member, TGF-β, almost three decades ago, there have been tremendous advances in our understanding of its complex biology. TGF-β?misregulation has been implicated in the pathogenesis of a variety of diseases, including cancer with a direct role in facilitating metastasis, fibrosis and inflammation. Consequently, TGF-β?is currently explored as a prognostic candidate biomarker of tumor invasiveness and metastasis;and it offers an attractive target for cancer therapy. Several anti-TGF-β?approaches, such as TGF-β?antibodies, antisense oligonucleotides and small molecules inhibitors of TGF-β?type 1 receptor kinase, have shown great promise in the preclinical studies. Here, we consider why the TGF-βsignaling pathway is a drug target, the potential clinical applications of TGF-β?inhibition, the issues arising with anti-TGF-β?therapy and how these might be adopted using personalized approaches with a special care for patient selection and timing of therapy so that we may bring forward all the potentials of targeting this pathway for therapeutic uses in both cancer, preferentially in combination therapy, and non-neoplastic diseases. 展开更多

The aim of the current research was to clone and to characterize the partial 66 kDa streptavidin-binding peptide(SBP)found in the germinated embryos of Pisum sativum L.var.Alaska.The pea(P.sativum var.Alaska)embryos possess prominent 66 kDa SBPs that gradually disappeared after few hours of germination in germinated embryos,but not in the cotyledons.The total RNA was isolated from embryos of P.sativum but could not be isolated from the cotyledons.The partial nucleotides sequences of 66 kDa SBPs of embryonic stalk(P.sativum var.Alaska)were cloned and identified using pMOSBlue vector.66 kDa(SBP)gene from the embryos of P.sativum var.Alaska possesses 327 bp having an open reading frame(ORF)region in a part of the gene that encoded for 108 amino acids.Alignment showed similarity among 66 kDa SBPs P.sativum var.Alaska,with P.sativum seed biotinylated protein(SBP65)and P.sativum sbp65a mRNA with DNA distance matrix between 0.0094 to 1.2676.MALDI-TOF mass spectrometry analysis of 66 kDa(SBP)proteins showed it had similar short peptides to 19 proteins found in different organisms,especially Convicilin precursor,and the seed biotinylated protein in P.sativum.The alignment results of both nucleotide sequences and amino acid residues either from cloning or MALDI-TOF-MS showed differences with related species,especially P.sativum.No mRNA was found in the cotyledons during seeds germination,which means no metabolic activities and this part may act only as food reservoirs for growing newly embryos. 展开更多

Current investigation has shown that human exposure to aflatoxins is not limited to the administration of contaminated cereals,but water is another possible source.This study was aimed to design easily applicable method to eliminate aflatoxin B2(AFB2)from contaminated drinking water.Electrospinning has been used for preparation of probiotic-coated polyvinyl alcohol(PVA)and cellulose acetate(CA)nanofibers.Both of these hybrid nanofibers were studied by scanning electron microscopy(SEM)and Fourier-transformed infrared spectroscopy(FT-IR).SEM showed the proper coating of probiotic strains(Kluyveromyces lactis CBS 2359 and Saccharomyces cerevisiae ATCC 9763)on both nanofiber types.Different areas(1-5 cm^(2))of the probiotic-nanofiber hybrid were used to enhance the removal of 20 ng/ml of aflatoxin B2(AFB2)from prepared AFB2-contaminated water over time.Results revealed that a 5 cm^(2) area of probiotic-coated PVA nanofibers can eliminate 97.5% of AFB2 as compared to 87.5%,90.5%,93.5%,and 95.5%,for 1 cm2,2 cm^(2),3 cm^(2),and 4 cm^(2),respectively,while probiotic-coated CA nanofibers were slightly less effective.Nevertheless,the cytotoxicity of probiotics-CA treated water on cultured human fibroblasts was almost 10 times lower than the cytotoxicity recorded in probiotics-PVA treated water.Therefore,results of the current research suggest that probiotics-polymer nanofiber membranes can be used as an extra stage in the water purification system for the treatment of AFB2-contaminated water. 展开更多

Background: Psoriasis is considered a common skin disease, marked by the production and elevation of inflammatory plaques that regularly shed scales resulting from extensive skin epithelial cell proliferation. T lymphocytes, neutrophils, and other leukocytes enter the irritated skin, resulting in epidermal keratinocyte hyperplasia, vascular hyperplasia, ectasia, and T lymphocyte, neutrophil other forms of leukocyte infiltration. Aim of the Work: the study aimed to investigate the role of IL-37 and VEGF gene expression in the pathogenesis of psoriasis in Egyptian patients. Methodology: Polymerase chain reaction techniques (PCR) were applied to detect VEGF in the skin homogenates of psoriasis patients. In addition, the ELIZA technique was applied to investigate IL-37 in skin homogenates. One hundred cases have been divided into two groups: 50 healthy volunteers as the group I healthy control;50 psoriasis patients as group II. PCR real-time technology was assessed through extracted DNA samples for VEGF amplification in skin homogenate. Result: Our results revealed that psoriasis patients significantly had a substantial reduction in IL-37 compared to the control group (p Conclusion: There is a significant inverse association between IL-37 and VEGF in psoriasis patients. Study findings revealed that IL-37 gene expression decreases while VEGF gene expression increases in psoriatic individuals. Such a measurement may be beneficial in determining the severity of the condition, as well as taking into consideration of the disease’s diagnosis. 展开更多

Background: Oxidative stress has been closely linked to the incidence of diabetic complications. Therefore, the aim of this research article was to study hyperglycemia and abnormal lipid profile in diabetic patient type 2 and its correlation with oxidative stress development as measured by 8-iso-PGF2α and 8-OHdG. Methods: Fifty (50) patients confirmed type 2 diabetes mellitus and eighty (80) non-diabetic control individuals were included in this study. All individuals were tested for blood glucose, lipid profile, 8-iso-PGF2α and 8-OHdG HdG. Results: The age of diabetic patients was observed to be ≥40 yrs in 96% and diabetes was frequently detected in female than in male patients (76% vs. 24%, p ere elevated in diabetic patients compared with control individuals (p < 0.0001) except in HDL-C, a significant decrease was recorded (p = 0.04). Serum 8-iso-PGF2α and 8-OHdG were elevated significantly in diabetic patients compared with non-diabetic control and a significant correlation was recorded between them (r = 0.6, p α was associated with Age (r = 0.394, p < 0.0001), FBG (0.553, p < 0.0001), LDL-C (r = 0.2, p = 0.023), TG (r = 0.176, p = 0.045) and TC (r = 0.2, p = 0.02). Also, 8-OHdG was associated with age (r = 0.558, p < 0.0001), FBG (r = 0.67, p < 0.0001), LDL-C (r = 0.28, p = 0.001), TG (r = 0.358, p < 0.0001) and TC (r = 0.33, p < 0.0001). Age, FBG, HbA1c, LDL-C, TG and TC showed a significant linear regression with 8-iso-PGF2α and 8-OHdG recording its role as significant predictors for the elevation of 8-iso-PGF2α and 8-OHdG. Therefore, hyperglycemia with oxidative stress development may play a role for dyslipidemia and diabetic complications. Conclusion: Diabetic patient’s type 2 has a higher rate of abnormal serum lipids and correlates significantly with lipid peroxidation and oxidized DNA bases as measured by 8-iso-PGF2α and 8-OHdG. Therefore, 8-iso-PGF2α and 8-OHdG could be used as oxidative biomarkers for evaluating diabetic patients with early prediction of its complications and cancer development. 展开更多

Emerging data now indicate and address the strong relationship between H. pylori infection and the incidence of Type 2 DM, a growing body of evidence suggests that the infection with H. pylori may be associated with insulin resistance, chronic inflammation, long-term diabetes complications, and cardiovascular risk factors. The present study was conducted to evaluate the relationship between the infection with Helicobacter pylori and disturbance in Lipid profile in Type 2 Diabetic patients. One hundred and five participants were enrolled, categorized into two groups of H. pylori positive cases and negative controls according to their results of H. pylori IgG antibodies. Subjects in both groups fill the structured questionnaire. Blood samples were drawn for measuring the FBS, 2hr-PP blood sugar, HbA1c, Lipid profile and oxidized LDL. The obtained results were statistically analyzed. The study methodology was approved by the Biomedical Ethics Committee in the Faculty of Medicine, Umm Al-Qura University, Makkah, KSA. 48 cases (45.7%) were diagnosed as H. pylori seropositive and 57 (54.3%) were negative. There is no significant difference in the mean age or mean BMI between the H. pylori negative and positive cases. Glycemic control was similar in the two groups. Total Cholesterol was higher in cases of positive H. pylori compared to negative controls (P < 0.001) and Triglycerides was significantly elevated too (P < 0.005). No significant difference in the levels of HDL-Cholesterol between the two groups, while the mean LDL-Cholesterol was found to be significantly increased in cases of H. pylori positive compared to negative controls (P < 0.001). Oxidized LDL levels in the positive cases was found to be increased significantly (P = 0.001) compared to negative controls. Infection with H. pylori is associated with increased levels of Total Cholesterol, Triglycerides, LDL-C and oxidized LDL in Type 2 Diabetic patients. 展开更多

A new study has demonstrated that the microbiome in the gastrointestinal system has a massive influence on the likelihood of getting a risk of serious complications,sometimes including autoimmune disorders,metabolic syndrome,impaired glucose tolerance,cerebrovascular disease,and various cancers[1].A growing body of evidence suggests that the microbiome develops in large part as a result of the foods we eat,with experiments showing that even small changes in diet may have major and short-lived effects on bacteria.Again,because of this deeper connection,altering the microbial community structure via a diet program just might have a significant positive impact on clinical effectiveness[2].Specialists became particularly inclined to reassess the effect food provided might have on the microbiome of the hypervisor by quickly assessing and evaluating the microbial communities ubiquitous in the human digestive system. 展开更多
