Natural Non Toxic Green Inhibitors of Murraya Koenigii, Withania Somnifera and Glycyrrhiza Glabra Extracts for Mild Steel in 8% H2SO4

By  means of polarization measurements UV, IR and weight loss study, it has been detected that the extract of Murraya koenigii, Withania somnifera and Glycyrrhiza glabra leaves can act as corrosion inhibitor for the sake of mild steel in 8% H2SO4 solution. These plants show good inhibition efficiency at particular concentrations of the acid. It is observed that plants extract act as better inhibitor on increasing their concentration. Here we have focused on the corrosion inhibition action of different plant extracts in H2SO4 medium. Keywords: Murraya koenigii, Withania somnifera, Glycyrrhiza glabra, Mild Steel, SEM.

A Replication Study of GWAS-Derived Lipid Genes in Asian Indians: The Chromosomal Region 11q23.3 Harbors Loci Contributing to Triglycerides

Recent genome-wide association scans (GWAS) and meta-analysis studies on European populations have identified many genes previously implicated in lipid regulation. Validation of these loci on different global populations is important in determining their clinical relevance, particularly for development of novel drug targets for treating and preventing diabetic dyslipidemia and coronary artery disease (CAD). In an attempt to replicate GWAS findings on a non-European sample, we examined the role of six of these loci (CELSR2-PSRC1-SORT1 rs599839; CDKN2A-2B rs1333049; BUD13-ZNF259 rs964184; ZNF259 rs12286037; CETP rs3764261; APOE-C1-C4-C2 rs4420638) in our Asian Indian cohort from the Sikh Diabetes Study (SDS) comprising 3,781 individuals (2,902 from Punjab and 879 from the US). Two of the six SNPs examined showed convincing replication in these populations of Asian Indian origin. Our study confirmed a strong association of CETP rs3764261 with high-density lipoprotein cholesterol (HDL-C) (p = 2.03×10−26). Our results also showed significant associations of two GWAS SNPs (rs964184 and rs12286037) from BUD13-ZNF259 near the APOA5-A4-C3-A1 genes with triglyceride (TG) levels in this Asian Indian cohort (rs964184: p = 1.74×10−17; rs12286037: p = 1.58×10−2). We further explored 45 SNPs in a ∼195 kb region within the chromosomal region 11q23.3 (encompassing the BUD13-ZNF259, APOA5-A4-C3-A1, and SIK3 genes) in 8,530 Asian Indians from the London Life Sciences Population (LOLIPOP) (UK) and SDS cohorts. Five more SNPs revealed significant associations with TG in both cohorts individually as well as in a joint meta-analysis. However, the strongest signal for TG remained with BUD13-ZNF259 (rs964184: p = 1.06×10−39). Future targeted deep sequencing and functional studies should enhance our understanding of the clinical relevance of these genes in dyslipidemia and hypertriglyceridemia (HTG) and, consequently, diabetes and CAD

Spin distribution as a probe to investigate the dynamical effects in fusion reactions

The spin distributions are measured for the compound nucleus 80Sr populated in the reactions 16O+64Zn and 32S+48Ti. The comparison of the experimental results for both the systems shows that the mean γ-ray multiplicity values for the system 32S+48Ti are lower than those for 16O+64Zn. The spin distribution of the compound nucleus populated through the symmetric channel is also found to be lower than the asymmetric channel. Present investigation directly shows the effect of entrance channel mass asymmetry on the reaction dynamics

Short review on environment and health effect of nanotoxicology

Nanotechnology is a brand-new area of scientific research that has revolutionized the manufacturing sector. The emphasis of this revolution was on the large-scale development of nano-based materials. Materials confinement in small structures, quantum mechanics, the high surface volumes ratio or other unusual properties, phenomena, and processes dominate nanoparticle behavior use of the nanomaterial containing items on the rise, posing a threat to the environment and human health. For the sake of human health and protection in the community, it's important to understand the toxicity of engineered nanomaterials or nano-based products. Nanotoxicology aims to identify potential toxins' toxicological practices in nanomaterials and these products to assess how these materials endanger human health. In this sense, nanoparticles and their fate in the atmosphere have been examined concerning air, water, and soil. Nanomaterials' health effects, such as their impact on various organ systems, have also been mentioned

Anti-Corrosive Behavior of the Seed Extract of Amomum sabulatum

An aqueous extract of Amomum sabulatum seeds was evaluated for anticorrosive effects on mild steel in the presence of HCl. Weight loss measurements were taken to determine the corrosion rate and inhibition efficiency at various concentrations. With the increasing concentrations of plant extract, the results showed an improvement in inhibition efficiency and a decrease in corrosion rate. In the presence of 1500 ppm concentration of plant extract, it has an inhibition efficiency of 82.08 % at 303 K. The scanning electron microscope was used to examine the surface, which proves that while the extract was there, a protective layer formed on the metal surface

Lepidium Didymium Plant Extract as Eco-Friendly Corrosion Inhibitor for Steel in Acidic Medium

256-264The efficiency of Lepidium didymium’s aerial part for corrosion inhibition, has been explored by applying weight loss analysis, SEM, and spectroscopy technique on mild steel corrosion in 1 M H2SO4. These techniques have been used to investigate the corrosion features of the steel in the absence and existence of various quantities of Lepidium didymium’s extract. With the aid of weight-loss statistics, the ability of the plant extract to construct a defensive film on steel surfaces is investigated. The formation of a protective membrane on the steel surface by the extract has also been supported by a surface morphology analysis (SEM). At 2500 mg/L, plant extract has the best inhibitory efficiency for steel in 1 M H2SO4 is 91.16%. Lepidium didymium extract is thought to be an effective inhibitor because of the presence of heteroatoms and multiple bonds

Rare adverse effects of anti tuberculous therapy − a case series

Tuberculosis is prevalent throughout the world and is a major public health problem in most developing countries. Standardized and directly observed treatment under NTEP (National Tuberculosis Elimination Programme) is currently recommended for drug-sensitive pulmonary tuberculosis in India. It is generally well tolerated, with few minor side effects. Severe side effects necessitating discontinuation of therapy are rare with standard TB treatment regimens. Drug-resistant tuberculosis (DR-TB) has become more common in recent years, posing a challenge to global efforts to control the disease. Therapy for DR-TB has been associated with many adverse effects. Therefore, close monitoring of patients on DR-TB therapy is necessary to ensure that adverse effects of drugs are recognized early by healthcare personnel and treated accordingly. This will improve drug compliance and, hence, treatment goals. Here we report three cases of tuberculosis who had unusual adverse effects while receiving anti-tuberculous medication, prompting drug discontinuation

Complete heart block due to diphtheritic myocarditis in the present era

Diphtheria continues to be reported from many parts of the world. Complete heart block is rare but often fatal complication of diphtheric myocarditis. We report six children with diphtheric myocarditis who presented with complete heart block. Three patients survived, one with persistent complete heart block. Aggressive supportive management including transvenous pacing may result in complete recovery in a significant number of children with diphtheric myocarditis

Effect of supplementation of butylated hydroxytoluene on post-thaw sperm viability, motility and membrane integrity of Hariana bulls

Aim: This study was aimed to see the beneficial effect of butylated hydroxytoluene (BHT) as a semen additive of Hariana bull semen. Materials and Methods: The study was carried out in Hariana bulls. Twenty-four ejaculates from two bulls were used for this study. Each ejaculate was extended with standard glycerolated egg yolk tris extender and supplemented with BHT at two concentrations as 0.5 mM (T1) and 1.0 mM (T2). After dilution, equilibration and 24 h of cryopreservation, the samples were analyzed for progressive motility, sperm viability and membrane integrity. Results: Progressive motility, sperm viability and sperm membrane integrity were significantly (p<0.05) increased in the samples fortified with BHT as compared to the control during the process of cryopreservation and thawing. The BHT concentration of 1 mM revealed better results as compared to 0.5 mM. Conclusion: Addition of 1.0 mM BHT was found better in cryopreservation of Hariana bull semen compared to 0.5 mM BHT and control samples. The addition of BHT has improved the sperm quality by acting as an antioxidant thereby reducing the lipid peroxidation of the sperms

Trans-dichlorooxovandium (IV) complex as a novel photoinducible DNA interstrand crosslinker for cancer therapy

Although DNA interstrand crosslinking (ICL) agents such as mitomycin C, cisplatin and psoralen serve as potent anticancer drugs, these agents are known to have dose-limiting toxic effects on normal cells. Moreover, tumor resistance to these agents has been reported. Here, we show that trans-dichlorooxovanadium (IV) complex of pyrenyl terpyridine (VDC) is a novel photoinducible DNA crosslinking agent. By a combination of in vitro and ex vivo experiments including plasmid-based assays, we find that VDC forms monoadducts on the DNA and can be activated by UV-A and visible light to generate DNA interstrand crosslinks. VDC efficiently activates Fanconi anemia (FA) pathway of DNA interstrand crosslink repair. Strikingly, photoinduction of VDC induces prolonged activation of cell cycle checkpoint and a high degree of cell death in homologous recombination (HR)/ICL repair defective cells. Moreover, VDC specifically targets cells that express pathological RAD51C mutants. These data imply that VDC can be potentially used for cancer therapy and suggest that tumors arising in patients with gene mutations in FA and HR repair pathway can be specifically targeted by a photoactivatable VDC
