Oesophageal cancer is a common and often fatal that has two main histological subtypes: oesophageal squamous cell carcinoma adenocarcinoma. Updated statistics on the incidence mortality of cancer, disability-adjusted life-years (DALYs) caused by disease, can assist policy makers in allocating resources for prevention, treatment, care cancer. We report latest estimates these 195 countries territories between 1990 2017, age, sex, Socio-demographic Index (SDI), using data from Global Burden...
Worldwide, both the incidence and death rates of pancreatic cancer are increasing. Evaluation burden its global, regional, national patterns is crucial to policy making better resource allocation for controlling risk factors, developing early detection methods, providing faster more effective treatments.Vital registration, vital registration sample, registry data were used generate mortality, incidence, disability-adjusted life-years (DALYs) estimates. We comparative assessment framework...
Stomach cancer is a major health problem in many countries. Understanding the current burden of stomach and differential trends across various locations essential for formulating effective preventive strategies. We report on incidence, mortality, disability-adjusted life-years (DALYs) due to 195 countries territories from 21 regions between 1990 2017.Estimates GBD 2017 were used analyse DALYs at global, regional, national levels. The rates standardised world population reported per 100 000...
Accurate, comprehensive, cause-specific mortality estimates are crucial for informing public health decision making worldwide. Incorrectly or vaguely assigned deaths, defined as garbage-coded mask the true cause distribution. The Global Burden of Disease (GBD) study has developed methods to create comparable, timely, estimates; an impactful data processing method is reallocation deaths a plausible underlying death. We identify pattern in world and present used determine their redistribution...
Proposing a scoring tool to predict COVID-19 patients' outcomes based on initially assessed clinical and CT features.All patients, who were referred tertiary-university hospital respiratory triage (March 27-April 26, 2020), highly clinically suggestive for had undergone chest scan included. Those with positive rRT-PCR or suspicious patients typical pulmonary manifestations considered confirmed additional analyses. Patients, outcome, categorized into outpatient, ordinary-ward admitted,...
Despite previous findings on the effects of cannabinoid and vanilloid systems learning memory, combined stimulation these 2 memory have not been studied. Therefore, in this study, we tested interactive rats by using passive avoidance (PAL) tests. Forty male Wistar were divided into following 4 groups: (1) control (DMSO+saline), (2) WIN55,212–2, (3) capsaicin, (4) WIN55,212–2 + capsaicin. On test day, a receptor type 1 (TRPV1) agonist, or (CB /CB ) both substances injected intraperitoneally....
Background. Providing efficient care for infectious coronavirus disease 2019 (COVID-19) patients requires an accurate and accessible tool to medically optimize medical resource allocation high-risk patients. Purpose. To assess the predictive value of on-admission chest CT characteristics estimate COVID-19 patients’ outcome survival time. Materials Methods. Using a case-control design, we included all laboratory-confirmed who were deceased, from June September 2020, in...
There are reports regarding the effects of intracellular Ca 2+ and synthesis release endocannabinoids. The secretion endocannabinoids depends on L-type calcium channel. present study evaluated involvement cannabinoid CB1 receptors in effect channel blocker verapamil passive avoidance learning (PAL) adult male rats. In this study, we examined an acute administration antagonist/inverse agonist AM251 following a chronic PAL. Male Wistar rats were administered (10, 25 50 mg/kg) or saline...
Background: Transport-related injuries (TIs) are a substantial public health concern for all regions of the world. The present study quantified burden TIs and deaths in Eastern Mediterranean region (EMR) 2017 by sex age. Methods: were estimated age, sex, country, year using Cause Death Ensemble modelling (CODEm) DisMod-MR 2.1. Disability-adjusted life years (DALYs), which quantify total lost due to premature death or disability, also per 100000 population. All estimates reported along with...
The interaction between L-type voltage-dependent Ca2+ channels and the endocannabinoid system (eCs) in synaptic plasticity is controversial. In present research, impact of acute administration URB597, as an breakdown inhibitor, was evaluated after chronic injection verapamil, a blocker, on inducing long-term potentiation (LTP) rat's hippocampal dentate gyrus (DG). Treatment male Wistar rats done using intraperitoneal(i.p) verapamil hydrochloride (n = 8) saline 10), solvent once day within 13...
Repeat contrast-enhanced MR imaging exposes patients with relapsing-remitting MS to frequent administration of gadolinium-based contrast agents. We aimed investigate the potential metabolite and neurochemical alterations visible gadolinium deposition on unenhanced T1WI in dentate nucleus using MRS.This prospective study was conducted a referral university hospital from January 2020 July 2021. The inclusion criteria for case control groups were as follows: 1) case: MS, (ribbon sign), >5...
