An improved rovibrational linelist of formaldehyde, H₂¹²C¹⁶O

Published high-resolution rotation-vibration transitions of H₂¹²C¹⁶O the principal isotopologue of methanal, are analyzed using the MARVEL (Measured Active Rotation-Vibration Energy Levels) procedure. The literature results are augmented by new, high-accuracy measurements of pure rotational transitions within the ground, ν_{3}, ν_{4}, and ν_{6} vibrational states. Of the 16 596 non-redundant transitions processed, which come from 43 sources including the present work, 16 403 could be validated, providing 5029 empirical energy levels of H₂¹²C¹⁶O with statistically well-defined uncertainties. All the empirical rotational-vibrational energy levels determined are used to improve the accuracy of ExoMol’s AYTY line list for hot formaldehyde. The complete list of collated experimental transitions, the empirical energy levels determined, as well as the extended and improved line list are provided as Supplementary Material

MicroRNAs (20a, 146a, 155, and 145) expressions in a sample of Iraqi patients with multiple sclerosis

Background: Multiple sclerosis is a devastating central nervous system autoimmune disorder that is characterized by a series of inflammations, demyelinations, and neurodegenerations that affect the brain and spinal cord. The epigenetic studies specially micro Ribonucleic acid expression represent an important field of researches that probably uncover the obscurities behind the multiple sclerosis pathogenesis. Objectives: to study the expression of micro Ribonucleic acids (20a, 146a, 155, and 145) in multiple sclerosis patients by the use of real time polymerase chain reaction. Patients and Methods: A case-control study was performed using real time polymerase chain reaction technique to measure the relative expression of micro Ribonucleic acids (20a, 146a, 155, and 145) in peripheral blood leukocytes of 25 newly diagnosed untreated multiple sclerosis patients and comparing them with that of 25 clinically apparent healthy controls . Results: Studying of micro Ribonucleic acids expression in multiple sclerosis patients revealed a significant down-regulation in micro Ribonucleic acid-20a while up- regulation of micro Ribonucleic acid-155 expression in multiple sclerosis patients in comparison to controls. Micro Ribonucleic acids -146a and 145 were not associated with significant changes in its expression in multiple sclerosis patients in comparison to controls. Conclusion: multiple sclerosis is associated with significant changes in micro Ribonucleic acids expression including micro Ribonucleic acid-20a, and micro Ribonucleic acid-155 but not micro Ribonucleic acid 146a and-145 that can be measured by real time polymerase chain reaction technique

Correlation of Total Cholesterol and Glucose in Serum of Iraqi Patients with Atherosclerosis and Diabetes Mellitus Type 2

Cholesterol is a fatty substance (lipid) classified as a waxy steroid of fat. It is absorbed by the intestine into blood stream and is packaged inside a protein coat a chylomicron. Blood glucose is a simple monosaccharide absorbed directly into the blood stream during digestion. The level of blood glucose normally represents a balance between the inflow of glucose into blood and it is uptake by the tissue. Atherosclerosis is a general term for a number of different medical conditions that affect the heart, this is occurs when the blood supply to a part of heart is interrupted, must commonly due to plaque, is build up in the coronary arteries consist of lipid cholesterol and calcium. It causes a damage of potential disease of heart muscle due to thickening and hardening of arteries. Diabetes mellitus is a disorder in which the level of blood glucose is persistently elevated above the normal range due to decrease secretion of insulin. The main objective of this study is to determine the concentrations of total cholesterol and glucose into blood serum of Iraq patients with atherosclerosis and diabetes mellitus type 2. This study included 60 specimens of patients with atherosclerosis and 60 patients with type 2 diabetes mellitus; their age range was 45-65 years. These patients were then matched by age and sex to 30 healthy individuals. Results revealed that there was highly significantly increased in the mean value of total cholesterol and glucose concentrations in patients of atherosclerosis (p<0.001) and diabetes mellitus (p<0.001) as compared with healthy individuals

Evaluation of Therapeutics for Severely Debilitating or Life‐Threatening Diseases or Conditions: Defining Scope to Enable Global Guidance Development

A significant regulatory gap exists to facilitate global development of therapeutics for nononcology severely debilitating or life-threatening diseases or conditions (SDLTs). In a 2017 publication, a streamlined approach to the development of treatments for SDLTs was proposed to facilitate earlier and continued patient access to new, potentially beneficial therapeutics.1 However, a major hindrance to broad adoption of this streamlined approach has been the lack of universally accepted, objective criteria to define SDLTs. This article serves to extend the 2017 publication by further addressing the challenge of defining SDLT scope in order to stimulate broader discussion and facilitate development of regional and ultimately international guidelines on the development of therapeutics for SDLTs. Using case examples, we describe key attributes of SDLTs and provide criteria for consideration of an SDLT scope definition
