GC-MS Analysis of Persicaria bistorta: Uncovering the Molecular Basis of Its Traditional Medicinal Use.

Persicaria bistorta is a perennial herb used traditionally in treating various ailments, including diarrhea, abdominal pain, and bleeding. In this study, we used gas chromatography-mass spectrometry (GC-MS) analysis to identify the chemical composition of Persicaria bistorta. The GC-MS analysis revealed the presence of several compounds, including flavonoids, tannins, saponins, and alkaloids. Among those, the most important from medicinal points of view are ethyl oleate (3%), cyclotetradecane (4.74%), dodecanoic acid (4.69%), hexadecanoic acid (5.61%), tetradecane (5.25%), cis-13-octadecenoic acid (10.91%), and bis(2-ethylhexyl) phthalate (32%). The GC-MS analysis of ethanolic fraction of Persicaria bistorta involved in antibacterial activity showed about 18 compounds. Among those, the most important from a medicinal and nutritional point of view are bis(2-ethylhexyl) phthalate (42.20%), 6-octadecenoic acid methyl ester, (Z)- (10.37%), ethyl oleate (6.84%), hexadecanoic acid methyl ester (6.67%), and methyl ester and oleic acid (5.27%). Reported biological antibacterial activity has shown that the main compound determined in both extracts was bis(2-ethylhexyl) phthalate, which has higher peak area percentage in ethanolic extract than in ethyl acetate fraction. Some oily compounds important for health because of their cis-conformation were also revealed in the given study like ethyl oleate and oleic acid. Overall, results suggest that Persicaria bistorta may have therapeutic potential and warrant further investigation. Further research is needed to confirm the efficacy and safety of Persicaria bistorta as a natural medicine and determine its active compounds' mechanisms of action.

Transition Metal-Decorated Mg12O12 Nanoclusters as Biosensors and Efficient Drug Carriers for the Metformin Anticancer Drug.

Drug carriers have been designed and investigated remarkably due to their effective use in the modern medication process. In this study, the decoration of the Mg12O12 nanocluster has been done with transition metals (Ni and Zn) for effective adsorption of metformin (anticancer drug). Decoration of Ni and Zn on a nanocluster allows two geometries, and similarly, the adsorption of metformin also provides two geometries. Density functional theory and time-dependent density functional theory have been employed at the B3LYP with 6-311G(d,p) level. The decoration of Ni and Zn offers good attachment and detachment of the drug, which is observed from their good adsorption energy values. Further, the reduction in the energy band gap is noted in the metformin-adsorbed nanocluster, which allows high charge transfer from a lower energy level to a high energy level. The drug carrier systems show an efficient working mechanism in a water solvent with the visible-light absorption range. Natural bonding orbital and dipole moment values suggested that the adsorption of the metformin causes charge separation in these systems. Moreover, low values of chemical softness with a high electrophilic index recommended that these systems are naturally stable with the least reactivity. Thus, we offer novel kinds of Ni- and Zn-decorated Mg12O12 nanoclusters as efficient carriers for metformin and also recommend them to experimentalists for the future development of drug carriers.

Primary hyperhidrosis: From a genetics point of view.

Primary hyperhidrosis is a disorder of profuse sweating which negatively influences a patient's quality of life and is caused because of over-activation of the sympathetic nervous system. It was believed that hyperhidrosis is a condition limited to only anxious individuals; however, this hypothesis is discredited now. It has been found that people with a positive family history of primary hyperhidrosis are likely to suffer from this condition, suggesting a strong genetic basis. Genetic analysis has revealed a dominant autosomal pattern of inheritance with a variable degree of penetrance and is a sex-independent trait. It is a heterogeneous condition both genetically and clinically as different studies revealed variable genetics and clinical factors. There are no proper criteria for diagnosis as it is not treated as disease by most affected persons. Various studies revealed opposing results in localizing disease gene loci, so further genetic research is needed to pinpoint genes responsible for causing this debilitating condition. Gene expression profiling of human anxiety-causing genes in hyperhidrotic sufferers will also help to devise new treatment modalities. This review highlights the current genetic studies on hyperhidrosis, which may prove to be helpful in understanding the molecular mechanism governing hyperhidrosis.

Trypsin Inhibitor Isolated From Glycine max (Soya Bean) Extraction, Purification, and Characterization.

The current study aims to isolate, purify, and characterize the trypsin inhibitor protein from seeds of soya beans, scientifically known as Glycine max. Its seeds were ground, and the powder was soaked several times using n-hexane. It was added to phosphate buffer saline (PBS) followed by filtration and centrifugation of the PBS dissolved extract. The supernatant was subjected to ammonium sulfate precipitation and about six fractions, 30% to 80% were prepared. The centrifuged pellets obtained from each fraction were dialyzed and run on SDS-PAGE. The trypsin inhibitor protein was precipitated and characterized in 30% pellet and molecular weight was 21.5 kDa compared to protein ladder (ThermoFisher 10-170 kDa). GC-MS analysis revealed the steroid derivatives such as stigmasterol, campesterol, beta-sitosterol, and gamma-tocopherol. Glycine max trypsin inhibitor could be used as a plant-derived drug to overcome the over-activation of trypsin without its real substrate (proteins) becoming activated and start auto digestion leading to pancreatitis.

Screening of immune epitope in the proteome of the Dabie bandavirus, SFTS, to design a protein-specific and proteome-wide vaccine for immune response instigation using an immunoinformatics approaches.

Tick-borne viruses are a major risk from tick bites, which could result in viral infectious diseases among animals and humans. Bunyavirus causes severe fever with thrombocytopenia syndrome (SFTS), with signs and symptoms including high fever, vomiting, diarrhea, thrombocytopenia (low platelet count), leukopenia (low white blood cell count), elevated liver enzyme levels, multiple organ failure, and has a 6%-30% case-fatality rate. To date no effective drug or vaccines are available thus need urgent research for therapeutics formulation. Hence, in this study, the computational meta-analysis approach was implemented that incorporates immunoinformatics to find potential B-cell, HTL (helper T lymphocytes) and T-cell epitopes derived from antigenic SFTS proteins to design multi-epitopes vaccines for the treatment of SFTS. The predicted T cell, B cell and HTL epitopes were shortlisted and checked for antigenic properties and allergenic features. The best epitopes were then joined together to model of multi-epitopes vaccines for specific proteins (replicase and glycoprotein) and proteome wide. The constructed models were validated using in silico molecular docking approach to evaluate binding potential of the designed best constructs with TLR3 (toll like receptor 3). Following the MEVC (multi-epitopes vaccine construct) injection, the response of the immune system was significantly stimulated, and anti-toxicity of induced antibodies was tremendously enhanced. Before being neutralized, the antigen titers remained high 5-10 days after injection of replicase, glycoprotein and proteome wide constructed vaccines. For each antigenic vaccine, a significant antibody response induction was observed. Further, in vivo trials are required to affirm the effectiveness of the constructed vaccine against SFTS.

Geranium wallichianum D. Don Ex Sweet Ameliorates Rheumatoid Arthritis by Curtailing the Expression of COX-II and Inflammatory Cytokines as Well as by Alleviating the Oxidative Stress.

Geranium wallichianum D. Don ex sweet traditionally been used as home remedy for backaches, joint pain, colic, and rheumatism. The objective of this study was to investigate the therapeutic benefits of plant in an adjuvant-induced arthritis paradigm. Immune-mediated rheumatoid arthritis was developed by injecting complete Freund's adjuvant (CFA) into the hind paws of rats and the aqueous methanolic crude extract was administered. The animals were physically monitored for changes in paw edema size and arthritic score. Hematological parameters and systemic inflammatory indicators evaluated. Genetic expressions of tumor necrosis factor (TNF-α), interleukins (IL-1ß, IL-6), necrosis factor (NF-κB), and cyclooxygenase (COX-II) enzyme were studied using real-time qPCR. PGE2 levels in blood were quantified through Enzyme Linked Immunosorbent Assay (ELISA). On the 14th day, Immunoglobulin E (IGE) exhibited a substantial decline in paw edema and arthritic score. At the doses of 500 mg/Kg (P ≤ .05) and 1000 mg/Kg (P ≤ .001), IGE significantly reduced TNF-α, interleukins, and COX-II mRNA expression. IGE significantly lowered the MDA levels at the doses of 500 and 1000 mg/Kg (13.18 ± .70 and 9.04 ± .26 µM/L respectively) as compared to arthritic control (30.82 ± 1.12 µM/L) group. IGE significantly improved the antioxidant enzyme activities of CAT and SOD (P ≤ .001) in treated animals. TNF-α, interleukins, and COX-II mRNA expression were also significantly reduced at the doses of 300 (P ≤ .05), 500 (P ≤ .01) and 1000 mg/Kg (P ≤ .001) which were expressed as fold changes. This study shows that Geranium wallichianum D. Don ex sweet has a strong potential to alleviate immune-mediated arthritis by lowering oxidative stress and downregulating the proinflammatory cytokines signaling mechanisms.

Biochemical Toxic Response of Phosphine on Human Health Estimated From Enzymatic Variance in Trogoderma granarium.

The primary purpose of the current study was to study the possible pernicious effects of phosphine gas on enzyme activity alterations in Trogoderma granarium to determine its harmfulness to human beings after its prolonged exposure and intake. The saline extract of the adult Khapra beetle was biochemically analyzed at different doses, that is, from 10ppm to 30ppm, to accurately evaluate the effects of various phosphine concentrations (LC30 and LC50) on 2 distinct strains of this insect pest gathered from different godowns of Pakistan as resistant (Chitral [Chi], Haroon Abad [Hbd], and Lahore [Lhr]) and susceptible (Faqeer wali [Fqw], Khanewal [Khw], and Rawalpindi [Rwp]) populations. Our experimental results suggest that the enzyme levels (AcP, AkP, ALAT, ASAT, LDH, and ICDH) seemed to be elevated with increasing dosage of phosphine from 10ppm to 30ppm in the resistant populace of the susceptible ones. It also illustrates that phosphine and its residues can inhibit the workability of certain enzymes that are vital for respiration and neuro reactions in hexapods and mammals. It has detrimental effects of phosphine on human health profile to consume stored food products containing such tenacious enemies.

Response of Iron Deficiency Markers to Blood Lead Levels and Synergistic Outcomes at Prenatal Stage.

Lead may be passed on from a mother to their unborn fetus. If she has been exposed to lead for an extended period, the lead deposited in their bones can be stimulated to be released into the bloodstream during gestation. This study was planned to examine blood lead level at the prenatal stage and its response to markers of iron deficiency during gestation. We collected 396 samples during the second trimester of gestation from women age 19 to 45 years. Hematological markers including hemoglobin, hepcidin, total iron-binding capacity (TIBC), ferritin, and blood iron were analyzed. For the detection of blood lead, we used Atomic absorption spectroscopy. The mean blood lead level of the control group was 3.25 ± .407 µg/dL, and in the iron deficiency group, it was 7.96 ± .502 µg/dL. At the same time, the women with iron deficiency anemia showed 22.12 ± 1.02 µg/dL of mean blood lead. Pearson's approach showed a non-significant negative correlation between blood lead and hepcidin, while hemoglobin, total iron-binding capacity, ferritin, and serum iron showed a significant (.01) negative correlation with blood lead. Blood lead has no direct effect on iron deficiency markers. In contrast, iron deficiency contributes to an increase in lead accumulation during pregnancy. Iron and lead both have an impact on the heme-biosynthetic pathways. The study revealed that pre-existing iron deficiency is connected with increased lead intake and can negatively impact health in gestational females.

Evaluation of the hepatoprotective activity of hydroalcoholic extract of Alhagi camelorum against valproic acid-induced hepatotoxicity in rats.

BACKGROUND AND PURPOSE: Despite many liver disorders, clinically useful drugs are scarce. Moreover, the available therapies are facing the challenges of efficacy and safety. Alhagi camelorum has been used in folk medicine globally for millennia to treat several ailments. Alhagi camelorum (Ac) is an old plant with a significant therapeutic value throughout Africa, Asia, and Latin America. Our goal was to determine the hepatoprotective activity of Alhagi camelorum against valproic acid induced hepatotoxicity using an animal model. EXPERIMENTAL APPROACH: The animals were segregated in 4-groups (6 male rats each) weighing 250-290 g. Group-1 animals were treated with normal saline, Group-2 animals were treated with VPA at the dose of 500 mg/kg i.p for 14 days consecutively, while Group-3 and 4 were treated with valproic acid (VPA) at the dose of 500 mg/kg i.p for 14 days along with 400 mg/kg and 600 mg/kg of Ac hydroalcoholic extract respectively. Subsequently, blood serum samples and liver tissues were collected for biochemical and histopathological analysis. Phytochemical screening was carried out to screen for phytochemical classes and HPLC analysis was conducted to screen polyphenols. The antioxidant activity was carried by different assays such as DPPH, SOD, NO etc. KEY RESULTS: The administration of Ac showed hepatoprotection at the doses of 400 and 600 mg/kg. Ac significantly reduces the elevated serum levels of liver biomarkers compared to the valproic acid-induced hepatotoxic group. These findings were confirmed with histopathological changes where Ac was capable of reversing the toxic effects of valproic acid on liver cells CONCLUSION: It is concluded that Ac showed significant hepatoprotective effects at different doses in the animal model used in this study.

Nephroprotective Effects of Alhagi camelorum against Cisplatin-Induced Nephrotoxicity in Albino Wistar Rats.

Alhagi camelorum (AC) is an old plant with a significant therapeutic value throughout Africa, Asia, and Latin America. The overuse of cisplatin (Cis > 50 mg/m2) is associated with observed nephrotoxicity, ototoxicity, gastrotoxicity, myelosuppression, and allergic reactions. Remedial measures are needed for the protection of nephrotoxicity against cisplatin. Thus, we investigated the nephroprotective effects of AC plant extract to prevent cisplatin-induced nephrotoxicity in albino Wistar rats. The presence of polyphenols, phenolic compounds, tannins, and saponins was revealed during phytochemical investigation, and a significantly intense antioxidant activity was recorded. There were no toxicological symptoms in the treated rats, and no anatomical, physiological, or histological abnormalities were found compared to the control rats. The results of correcting cisplatin-induced nephrotoxicity revealed that the extract has a significant ability to treat kidney damage, with most parameters returning to normal after only three weeks of therapy. It is concluded that co-administration of cisplatin with AC extract showed exceptional nephroprotective effects at a dose of 600 mg/kg for Cis-induced nephrotoxicity.

J. sambac has shown good antioxidant potential as well as prolonged the noradrenaline induced platelet adhesion. The vasorelaxant and cardioprotective effects in both in vivo and ex vivo experiments, which are enabled by activation of muscarinic receptor and/or releasing the nitric oxide and by reducing the adrenaline, induced oxidative stress, justifying its usage in cardiovascular disorders.

Serum hepcidin response as a marker of iron deficiency during second trimester of pregnancy: A multicenter cohort study in Lahore.

Iron deficiency diagnosis is a key health priority during pregnancy. The precise determination of indicators is needed for the evaluation of iron deficiency. In the present study, we investigated the diagnostic features of hepcidin concentration as an iron deficiency assay during the second trimester of pregnancy. We collected 401 venous blood samples of pregnant females from 4 separate birthing hospitals. All the females were within 13-26 weeks of their pregnancy and without any comorbid conditions. The complete blood count, total iron binding capacity, ferritin, serum iron and serum hepcidin were determined. The women were categorized as being non-iron deficient (N-ID), iron deficient (ID), or with iron deficiency anemia (IDA). The mean hepcidin values for examined groups were, i.e., non-iron deficiency was 31.45±4.70 (µg/L), iron deficiency 20.47±2.48 (µg/L) and iron deficiency anemia was 17.33±1.90 (µg/L). The N-ID's hemoglobin mean levels were 13.05±0.10g/dL, ID 12.66±0.05g/dL and the IDA 8.11±00.12g/dL. In this article variations in hepcidin levels between N-ID, ID and IDA women are uncovered and it is reported that the lower hepcidin levels diagnosed in IDA are closely linked to hemoglobin in Pakistani women. Hence it is concluded that hepcidin can be a valuable marker in identifying iron deficiency and iron deficiency anemia during the second trimester of pregnancy, according to the Pearson's correlation data.

Potential antibacterial activity of coumarin and coumarin-3-acetic acid derivatives.

Coumarin and coumarin-3-acetic acid derivatives were synthesized by reacting phenols with malic acid, ethyl acetoacetate and ethyl acetylsuccinate in appropriate reaction conditions. All synthesized compounds were subjected to test for their antimicrobial activities against variety of gram positive (Bacillus subtilis, Staphylococcus aureus) and gram negative bacterial stains (Shigella sonnei, Escherichia coli) by agar dilution method. Several of them exhibited appreciable good antibacterial activity against the different strains of gram positive and gram negative bacteria. These findings suggest a great potential of these compounds for screening and use as antibacterial agents for further studies with a battery of bacteria.
