1Carcinogenic Helicobacter pylori in gastric pre-cancer and cancer lesions: Association with tobacco-chewing显示文摘AIM:To investigate the low gastric cancer incidence rate relative to the highly prevalent Helicobacter pylori(H.pylori)infection;data relevant to H.pylori infection during gastric carcinogenesis in Indian patients is currently lacking.METHODS:The present study examines the prevalence of H.pylori infection in DNA derived from 156endoscopic gastric biopsies of different disease groups that represent gastric pre-cancer[intestinal metaplasia(n=15),dysplasia(n=15)],cancer[diffuse adenocarcinoma(n=44),intestinal adenocarcinoma(n=21)],and symptomatic but histopathologically-normal controls(n=61).This was done by generic ureC polymerase chain reaction(PCR)and cagA-specific PCR that could specifically identify the carcinogenic H.pylori strain.RESULTS:Our analysis showed the presence of H.pylori infection in 61%of symptomatic histopathologically-normal individuals,however only 34%of control tissues were harboring the cagA+H.pylori strain.A similar proportion of H.pylori infection(52%)and cagA(26%)positivity was observed in the tumor tissue of the gastric cancer group.In comparison,H.pylori infection(90%)and cagA positivity(73%)were the highest in gastric pre-cancer lesions.In relation to tobacco and alcohol abuse,H.pylori infection showed an association with tobacco chewing,whereas we did not observe any association between tobacco smoking or alcohol abuse with prevalence of H.pylori infection in the tissue of any of the patient groups studied.CONCLUSION:High incidence of H.pylori infection and carcinogenic cagA positive strain in pre-cancer lesions during gastric carcinogenesis may beArvind Pandey Satyendra Chandra Tripathi Sutapa Mahata Kanchan Vishnoi Shirish Shukla Sri Prakash Misra Vatsala Misra Suresh Hedau Ravi Mehrotra Manisha DwivediZ Alok C Bharti 2014World Journal of Gastroenterology2014,20,22:4
2Downregulation of miRNA-21 and cancer stem cells after chemotherapy results in better outcome in breast cancer patients显示文摘Epigenetic modifications have been observed as a decline in miRNA-21 expression and breast cancer stem cell(CSC)population after 3 cycles of standard chemotherapy.The epigenetic response(miRNAs expression)and CSCs are also correlated in patients with Breast Cancer.In patients who tolerated chemotherapy well,miRNA-21(non-coding RNA)expression decreased significantly after three cycles of chemotherapy.The miRNA-21 expression in breast cancer tissue was quantified by quantitative PCR(real-time PCR)using the standard protocol.In addition,breast CSCs(CD44+/CD24-)were also decreased in these patients.The miRNA-21 regulates cell division,proliferation,and autophagy of cancerous cells(as it targets phosphatase and tensin homolog/AKT/transcription factor EB/programmed cell death 4/autophagy-related protein 5 and chemotherapy also produces similar effects),thereby contributing to these benefits.Therefore,when all of the targets on genes have been explored by mimic miRNA,chemotherapy combined with anti-miRNA21 therapy may prove useful in the care of cancer patients.Shailendra Dwivedi Puneet Pareek Jeewan Ram Vishnoi Praveen Sharma Sanjeev Misra 2022World Journal of Stem Cells2022,14,4:3

13The Renaissance of Functional Hybrid Transition-Metal Halides显示文摘CONSPECTUS:There is an extensive history of research on both inorganic and hybrid metal halides,with the latter being first reported in the 1960s.Although work on hybrid systems has progressed steadily over the last 60 years,it has enjoyed a major renaissance during the last 5 years.This has arisen as a consequence of the 2009 discovery of the outstanding optoelectronic properties of hybrid lead halides,such as(MA)PbI_(3)(MA=methylammonium),and the recognition that there are many opportunities for equally exciting discoveries with compounds of the transition metals.Some of the early work on hybrid transition-metal halides put more emphasis on crystal structures but less on properties.In the modern era,we aim to grasp both the structure and properties,with a new twist.In this Account,we shall explore the recent developments in hybrid transition-metal halides with a focus on work in four main areas:magnetism,photoluminescence,semiconductivity,and spintronics.Our work on magnetism centers on the Ru-based hybrid halides,where the structural types are diversely composed of vacancy-ordered double perovskite,as well as chain-like one-dimensional structures and layered double perovskite(LDP)when paired with a(1+)metal.We explore their magnetic properties and find that their spin−orbit coupling(SOC)behavior can be tuned through changing the A cation and the halide.In the luminescence section,we focus on our recent works on hybrid tetrahedral Mn(II)bromides and Cu(I)and Ag(I)iodides.We correlated our newly discovered 0D A_(m)MnBr_(4)(A=organic cation,m=1 or 2)compounds with previous reports,and generated a trend where the photoluminescence quantum yield(PLQY)increases with larger Mn−Mn distances.The flexible organic cation becomes the most important tool here to tune the structure−PLQY relations.Cu(I)and Ag(I)iodides coordinated with iodides and organic ligands produce new crystal structures with intense PL.For the semiconducting properties,we explore the Pt-based vacancy-ordered double perovskite and hybrid bismuth and indium-based LDPs to show the structural evolution with different choices for the organic cation,the metal and the halide;these have a strong influence on the optical properties.The LDPs specifically exhibit high structure tunability,with a wide range of(1+)and(3+)metal choices,and are exempt from some of the limitations of 3D double perovskite.In the last section,we introduce the recent progress on hybrid transition-metal-based ferroelectrics and spintronic materials.We successfully demonstrate the utilization of chiral Cu(II)chlorides for circularly polarized light(CPL)detection,showing the high anisotropy of the photoresponsivity.We also highlight the work that the authors have contributed in these areas and suggest several exciting opportunities for future developments.Lingling Mao Jian Chen Pratap Vishnoi Anthony K.Cheetham 2022Accounts of Materials Research2022,3,4:1
