Background: Currently, colistin-resistant pathogens emerged has become a global health concern. This study assessed the distribution of mcr-1 to mcr-5 variants with phenotypic colistin-resistance in bacterial isolates from urinary tract infection (UTI) patients Bangladesh.Methods: A cross-sectional was conducted between April 2017 and March 2018 enroll uncomplicated UTI patients, 142 urine samp...
Small hydrophobic hormones like steroids control many tissue-specific physiological responses in higher organisms. Hormone response is characterized by changes in gene expression, but the molecular details connecting target-gene transcription to the physiology of responding cells remain elusive. The salivary glands of Drosophila provide an ideal model system to investigate gaps in our knowledge...
Juvenile hormone (JH) regulates many developmental and physiological events in insects, but its molecular mechanism remains conjectural. Here we report that genetic ablation of the corpus allatum cells of the Drosophila ring gland (the JH source) resulted in JH deficiency, pupal lethality and precocious and enhanced programmed cell death (PCD) of the larval fat body. In the fat body of the JH-d...
ABSTRACT Animal steroid hormones initiate signaling by passive diffusion into cells and binding to their nuclear receptors regulate gene expression. can via G protein-coupled (GPCRs); however, the underlying mechanisms are unclear. Here, we show that a newly discovered ecdysone-responsive GPCR, ErGPCR-3, transmits hormone 20-hydroxyecdysone (20E) signal 20E promoting its entry in lepidopteran i...
Antimicrobial medications were given to patients with this illness without antimicrobial susceptibility since recent statistics on SARS-C0V-2 showed that bacterial infection increased mortality rate and lowered clearance of the virus. The goal study was detect co-infecting pathogen(s) analyze their antibiotic resistance profiles in confirmed SARS-CoV-2 cases Oyo State, Nigeria. 400 symptomatic ...
Autophagy requires the conjugation of autophagy-related protein 12 (ATG12) to autophagy-related protein 5 (ATG5) through covalent attachment. However, the signals regulating ATG12-ATG5 conjugation are unclear. The larval midgut of lepidopteran insects performs autophagy and apoptosis sequentially during the transition of larvae to pupae under regulation by the steroid hormone 20-hydroxyecdysone...
سابقه و هدف: انتروباکترها متعلق به خانواده انتروباکتریاسه‌اند که دارای مشخصات متنوعی از نظر فنوتیپ و ژنو‌تیپ هستند. در مورد انتروباکترکلوآکه، شش گونه مشابه از نظر فنوتیپیک و ژنوتیپیک در یک کمپلکس به عنوان کمپلکس انتروباکترکلوآکه گنجانده شده‌اند و جدایه‌های وابسته آن جزء بیش‌ترین جدایه‌های عامل ایجاد عفونت‌های فرصت‌طلب سخت در بیمارستان می‌باشند. بر اساس توالی ژن hsp60 در این کمپلکس 13 خوش...
Polycyclic Aromatic Hydrocarbons (PAHs) are among of potentially hazardous chemicals for environment and cause health concern. These compounds exhibit carcinogenic and/or mutagenic properties and are listed by the United States Environmental Protection Agency (USEPA) as priority pollutants. Polycyclic Aromatic Hydrocarbons are hardly degraded and therefore bioremediation is often considered as...
Molecular interactions between male and female factors during mating profoundly affect the reproductive behavior and physiology of female insects. In natural populations of the malaria mosquito Anopheles gambiae, blood-fed females direct nutritional resources towards oogenesis only when inseminated. Here we show that the mating-dependent pathway of egg development in these mosquitoes is regulat...
A number of insect effector genes activated by the steroid hormone 20-hydroxyecdysone (20E) are dually controlled by the ecdysteroid receptor (EcR/USP) and products of ecdysteroid early responsive genes (E74, E75, and Broad). However, the molecular mechanism of this dual action is poorly understood. Here we examined transcriptional activation of the vitellogenin (Vg) gene in the yellow fever mo...
