Filter by:Covid-19 infection was declared a global pandemic by WHO on March 11, 2020. GRP78 protein is known to be involved in the intrusion of numerous viruses. Our current study tries to provide some insight into the variation of GRP78 protein levels in patients with Covid-19(-) pneumonia, Covid-19(+) pneumonia, and CT negative Covid-19 infection in comparison to the normal population through a larger number of cases. 42 patients who have Covid-19(-) pneumonia; 72 patients who have Covid-19 infection (30 pneumonia,42 CT negative patients) and 30 patient who have no known diseases (control group) will be included in the study after the clinical and radiological evaluation. Serum GRP78 levels of the subjects will be measured through a commercially available enzyme-linked immunosorbent assay (ELISA) kit.
To evaluate endoplasmic reticulum stress in women with recurrent pregnancy loss and those who had healthy births in the same age group. The level of the unfolded protein X box binding protein 1 (XBP-1) is measured. It is aimed to show the effect of endoplasmic reticulum stress on recurrent pregnancy loss.
The correlation between painful symptoms (dysmenorrhea, dysparonia, dysuria, chronic pelvic pain) symptoms and endoplasmic reticulum stress was investigated in 86 patients diagnosed with endometriosis. For this, xbp-1 (x box binding protein-1) level was measured in patients. XBP-1 is an endoplasmic reticulum stress indicator and is known to be involved in pain pathogenesis.
To determine the efficacy of metformin in reducing the rate of symptomatic YF17D infection, and to elucidate the effects of metformin on YF17D viremia and the downstream adaptive immune response, we hereby propose a randomised, double-blind, placebo-controlled clinical trial that is coupled with a system biology approach. We plan to recruit 44 healthy volunteers aged 21-40 years, with a Body Mass Index of 20-25 kg/m2, have no known drug allergies and are not currently receiving regular immune-modulating therapy such as metformin, NSAIDs, paracetamol, corticosteroids or statins. The age range that we propose will ensure that our volunteers are likely to be healthy and not be on long-term medication for other concurrent medical conditions. This would abrogate the confounding effect of YF17D infection enhancement by cross reactive antibodies that we have previously shown. Informed written consent will be obtained before any physical examination is performed. All consented subjects will undergo screening which includes a full physical examination, vital signs measurement, clinical laboratory tests and urine pregnancy test (for female subjects of child-bearing potential) Eligible subjects will be randomized 1:1 to either metformin 1000mg or placebo twice daily for 7 consecutive days (Days 1-7). On Day 4, subjects will be administered one dose of YF17D before study drug dosing. Aim 1 tests the hypothesis that prophylactic metformin reduces ER stress and thus attenuates the post-infection pro-inflammatory response for reduced rate of symptomatic outcome. The primary objective for Aim 1 is to determine the efficacy of metformin in reducing the rate of symptomatic YF17D infection using a randomized placebo-controlled clinical trial. Aim 2 explores the effectiveness of metformin, either through its action on ER stress or other pathways that differentially regulate the expression of pro- and anti-viral host factors, in inhibiting live attenuated vaccine infection and downstream adaptive immune responses. The primary objective for Aim 2 is to elucidate the effects of metformin on YF17D viremia and the downstream adaptive immune response.
Investigate the change in endoplasmic reticulum stress after cancer surgery according to different anaesthetics including propofol and sevoflurane.
The purpose of this study is to investigate whether Endoplasmic Reticulum (ER) stress pathway is activated in peripheral tissues (adipose tissue) in insulin resistant diabetic patients compared to healthy subjects normoglycemic matched for age and sex an to investigate whether ER stress pathway can be activated in response to insulin. Indeed, some preliminar on rates studies shows that ER stress pathway is activated by insulin in liver and adipose tissue showing that hyperinsulinemia might help trigger stress path ER. For this, we propose a case control study of type 2 diabetic patients vs control subjects in which markers of ER stress will be evaluated from abdominal subcutaneous adipose tissue obtained before and after euglycemic hyperinsulinemic. We chose to consider adipose tissue subcutaneous rather than visceral adipose tissue for obvious reasons of lesser invasiveness.
Rates of cardiovascular disease and diabetes are more than 2-fold greater in HIV infected people than the general population. Protease inhibitor booster antiretroviral therapy (PI-ART) which is used by ~50% of HIV infected people in the USA is an established risk factor for diabetes. Tauroursodeoxycholic acid (TUDCA), a naturally occurring bile salt, improves insulin sensitivity in HIV uninfected subjects, although the mechanisms for these benefits are unclear. This study will explore the hypothesis that TUDCA will improve insulin action in people with HIV who are receiving PI-ART. Further, this project will clarify the molecular mechanisms responsible for these improvements potentially benefiting society, irrespective of HIV status.
