Study Of Impact Of Diet And Lifestyle Factors On Prevalence Of Gastric Cancer

The second most frequent cancer worldwide and the second greatest cause of cancer-related death is gastric cancer. However, the incidence rates in various geographical areas vary significantly. While the prevalence of stomach cancer has been declining, there are reports that in some areas, the prevalence of gastric cardia cancer is increasing. Infection with Helicobacter pylori (H. pylori) is a significant contributor to the development of non-cardia gastric cancer, and evidence has been gathered supporting the primary prevention of gastric cancer by the elimination of H. pylori. Additionally implicated are metabolic, dietary, and behavioral variables. Although addressing these additional factors may improve health, it is uncertain how doing so will actually affect cancer prevention. Anatomically, gastric adenocarcinomas and gastro-esophageal junction adenocarcinomas are distinguished, and histologically, different usage and intestine kinds are distinguished. Helicobacter pylori (H pylori) infection and dietary variables are the primary risk factors for distal gastric cancer, but obesity and gastroesophageal reflux syndrome are significant contributors to the development of proximal stomach cancer. Eliminating H. pylori is a crucial primary prevention measure for stomach cancer. A healthy lifestyle will help avoid stomach cancer. This includes cutting back on red meat and salted and smoked foods, increasing the number of fruits and vegetables in your diet, quitting smoking, and reducing your alcohol use. The review article focuses on mainly the impact of different dietary factors on the incidence of gastric cancer

Thiosemicarbazone complexes of the platinum metals. A story of variable coordination modes

Salicylaldehyde thiosemicarbazone (H2saltsc) reacts with [M(PPh3)3X2] (M = Ru, Os; X = Cl, Br) to afford complexes of type [M(PPh3)2(Hsaltsc)2], in which the salicylaldehyde thiosemicarbazone ligand is coordinated to the metal as a bidentate N,S-donor forming a four-membered chelate ring. Reaction of benzaldehyde thiosemicarbazones (Hbztsc-R) with [M(PPh3)3X2] also affords complexes of similar type, viz. [M(PPh3)2(bztsc-R)2], in which the benzaldehyde thiosemicarbazones have also been found to coordinate the metal as a bidentate N,S-donor forming a four-membered chelate ring as before. Reaction of the Hbztsc-R ligands has also been carried out with [M(bpy)2X2] (M = Ru, Os; X = Cl, Br), which has afforded complexes of type [M(bpy)2(bztsc-R)]+, which have been isolated as perchlorate salts. Coordination mode of bztsc-R has been found to be the same as before. Structure of the Hbztsc-OMe ligand has been determined and some molecular modelling studies have been carried out determine the reason for the observed mode of coordination. Reaction of acetone thiosemicarbazone (Hactsc) has then been carried out with [M(bpy)2X2] to afford the [M(bpy)2(actsc)]ClO4complexes, in which the actsc ligand coordinates the metal as a bidentate N,S-donorformingafive-membered chelate ring. Reaction of H2saltsc has been carried out with [Ru(bpy)2Cl2] to prepare the [Ru(bpy)2(Hsaltsc)]ClO4 complex, which has then been reacted with one equivalent of nickel perchlorate to afford an octanuclear complex of type [Ru(bpy)2(saltsc-H)4Ni4](ClO4)4

Unprecedented chemical transformation of semicarbazones mediated by wilkinson's catalyst

para-Nitrobenzaldehyde semicarbazone undergoes an unusual chemical transformation upon reaction with [Rh(PPh<SUB>3</SUB>)<SUB>3</SUB>Cl] in the presence of trialkyl and dialkylamines (NR<SUB>2</SUB>R&#8216;; R = Et, <SUP>i</SUP>Pr, <SUP>n</SUP>Bu; R&#8216; = H or R&#8216; = R) via dissociation of the C-NH<SUB>2</SUB> bond and formation of a new C-NR<SUB>2</SUB> bond (where the NR<SUB>2</SUB> fragment is provided by the amine). The transformed semicarbazone ligand binds to rhodium as a dianionic C,N,O-donor to afford complexes of type [Rh(PPh<SUB>3</SUB>)<SUB>2</SUB>(CNO-NR<SUB>2</SUB>)Cl] (CNO-NR<SUB>2</SUB> = the coordinated semicarbazone ligand). Another group of semicarbazones (viz. salicylaldehyde semicarbazone, 2-hydroxyacetophenone semicarbazone, and 2-hydroxynaphthaldehyde semicarbazone) has also been observed to undergo a similar chemical transformation upon reaction with [Rh(PPh3)3Cl] under similar experimental conditions as before, and these transformed semicarbazones bind to rhodium as dianionic O,N,O-donors affording complexes of the type [Rh(PPh<SUB>3</SUB>)<SUB>2</SUB>(ONO<SUP>n</SUP>-NR<SUB>2</SUB>)Cl] (ONO<SUP>n</SUP>-NR<SUB>2 </SUB>= the coordinated semicarbazone ligand; n = 1-3). The structure of the [Rh(PPh<SUB>3</SUB>)<SUB>2</SUB>(CNO-NEt<SUB>2</SUB>)Cl] and [Rh(PPh<SUB>3</SUB>)<SUB>2</SUB>(ONO<SUP>2</SUP>-NR<SUB>2</SUB>)Cl] complexes has been determined. All the complexes show characteristic <SUP>1</SUP>H NMR signals. They also show intense absorptions in the visible and ultraviolet region. Cyclic voltammetry on the complexes shows an oxidative response within 0.52-0.97 &#957; versus SCE and a reductive response within -1.00 to -1.27 V versus SCE, where both the responses are believed to be centered on the semicarbazone ligand

Modulation of TLR 3, 7 and 8 Expressions in HCV Genotype 3 Infected Individuals: Potential Correlations of Pathogenesis and Spontaneous Clearance

Background. Hepatitis C virus is the major cause of chronic hepatitis worldwide which finally leads to the development of hepatocellular carcinoma. Toll like receptors (TLRs) play an important role in the course of many viral infections, but the role of TLRs in HCV pathogenesis has not been well elucidated so far. Objective. The aim of this study was to analyse the mRNA expression of TLRs 3, 7, and 8 in different stages of HCV infection including chronic, cirrhosis, interferon treated resolved, and relapsed cases. Methodology. Total RNA from whole blood was extracted and mRNA expression of TLRs 3, 7, and 8 genes was analyzed by quantitative real-time RT-PCR using β-Actin gene as an internal control. Results. This study consisted of 100 HCV infected individuals and twenty healthy controls. TLR 3 expression was found to be significantly elevated in individuals who had spontaneously cleared the virus (p<0.001), whereas TLR 7 was found to be 3.26 times more elevated in patients with cirrhosis of liver. In IFN induced individuals, TLR 8 expression levels were found to be 2.28-fold elevated as compared to control population. Conclusion. TLRs 3, 7, and 8 are prime biomarker candidates for HCV infection mRNA expression analysis which might improve current therapeutic approaches
