The occurrence of ST elevation myocardial infarction (STEMI) and non-STEMI in patients with post traumatic stress disorder (PTSD) using the large nationwide inpatient sample (NIS).

Background: PTSD leads to increased levels of stress hormones and dysregulation of the autonomic nervous system which may trigger cardiac events. The goal of this study is to evaluate any association between PTSD and the occurrence of STEMI and NSTEMI using a large database.

Method: Using the Nationwide Inpatient Sample (NIS) and ICD-9 codes from 2005 to 2014 (n=1,621,382), we performed a univariate chi-square analysis of in-hospital occurrence of STEMI and NSTEMI in patients greater than 40 years of age with and without PTSD.

Suspected colchicine-induced late myocardial rupture occurring after the late presentation of acute inferior ST-elevation myocardial infarction.

Colchicine is one of the established drugs of choice for post-myocardial infarction (MI) induced pericarditis, given its anti-inflammatory properties. Recently, colchicine received FDA approval for secondary prevention of atherosclerotic cardiovascular disease, which leads to concerns regarding its anti-healing effects on myocardial tissue post-infarction. We present a case of a suspected colchicine-induced myocardial rupture in an elderly male, who presented with a syncopal episode while on colchicine three weeks after the late presentation of infero-posterior ST-elevation myocardial infarction.

A comprehensive review of the ten main platelet receptors involved in platelet activity and cardiovascular disease.

Cardiovascular disease (CVD) is a major cause of death worldwide. Although there are many variables that contribute to the development of this disease, it is predominantly the activity of platelets that provides the mechanisms by which this disease prevails. While there are numerous platelet receptors expressed on the surface of platelets, it is largely the consensus that there are 10 main platelet receptors that contribute to a majority of platelet function.

Serine-rich repeat proteins: well-known yet little-understood bacterial adhesins.

Serine-rich-repeat proteins (SRRPs) are large mucin-like glycoprotein adhesins expressed by a plethora of pathogenic and symbiotic Gram-positive bacteria. SRRPs play major functional roles in bacterial-host interactions, like adhesion, aggregation, biofilm formation, virulence, and pathogenesis. Through their functional roles, SRRPs aid in the development of host microbiomes but also diseases like infective endocarditis, otitis media, meningitis, and pneumonia.

Hyperpyrexia in a previously healthy pregnant female with COVID pneumonia: a case report and review of the literature.

Background: Infection due to the SARS-CoV-2 virus can have a wide range of presentations from asymptomatic/mildly symptomatic to severe disease with multiorgan failure. Fever is a common symptom. But hyperpyrexia defined as temperature > 41.

Assessing suitability of commercial fibre reinforced plastic solar still for sustainable potable water production in rural India through detailed energy-exergy-economic analyses and environmental impacts.

Fibre reinforced plastic (FRP) basin solar still is manufactured and marketed commercially in developing/underdeveloped nations. Unfortunately, these commercial units have not been widely adopted by the public due to its low water productivity. In the present investigation, an effort has been made to assess the performance and enviro-economic aspects of the commercial unit and its low-cost improved versions under Coimbatore climatic conditions through real-time experiments and mathematical models, respectively.

Eliminating acetate formation improves citramalate production by metabolically engineered Escherichia coli.

Background: Citramalate, a chemical precursor to the industrially important methacrylic acid (MAA), can be synthesized using Escherichia coli overexpressing citramalate synthase (cimA gene). Deletion of gltA encoding citrate synthase and leuC encoding 3-isopropylmalate dehydratase were critical to achieving high citramalate yields. Acetate is an undesirable by-product potentially formed from pyruvate and acetyl-CoA, the precursors of citramalate during aerobic growth of E.

Phosphatases and phosphate affect the formation of glucose from pentoses in .

Metabolically engineered MEC143 with deletions of the , , , , and genes converts pentoses such as arabinose and xylose into glucose, with the dephosphorylation of glucose-6-phosphate serving as the final step. To determine which phosphatase mediates this conversion, we examined glucose formation from pentoses in strains containing knockouts of six different phosphatases singly and in combination. Deletions of single phosphatases and combinations of multiple phosphatases did not eliminate the accumulation of glucose from xylose or arabinose.
