Hair color is one of the most visible and heritable traits in humans. Here, we estimated heritability by structural equation modeling (N = 20,142), and performed a genome wide association (GWA) analysis (N = 7091) and a GCTA study (N = 3340) on hair color within a large cohort of twins, their parents and siblings from the Netherlands Twin Register (NTR). Self-reported hair color was analyzed as...
اثر فعالیت ورزش کوتاه مدت بر سطح آدیپونکتین و حساسیت انسولین در بیماران دیابتی نوع 2: یک گزارش کوتاه
Background and Objective: The accumulating evidence indicates that systemic inflammation is related with obesity and type II diabetes. In the present study, serum adiponectin and insulin sensitivity responses to a short-time exercise test were investigated in type II diabetic patients. Materials and Methods: In this semi-experimental study, fasting level of serum adiponectin, glucose, insul...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
Background: The most important demand of people in disasters is health and the provision of coordinated, integrated, continuous, and accessible health services. Effective disaster management depends on anticipating and identifying disaster problems and considering the necessary facilities. The aim of this study was to evaluate the safety status and functional, structural, and non-structural pre...
Background: Despite some evidences about protective or triggering role of opium use in patients with coronary artery disease, the exact role of opium is still under question. The current study aimed to address the relation of opium dependence on the severity and extension of myocardial infarction (MI) and its related mortality. Methods: The study population consisted of 460 consecutive patients...
Probabilistic sequence models estimated from large corpora typically require smoothing techniques to reserve some probability mass for unobserved events. These techniques fail to distinguish between events unobserved due to sampling limitations, sampling zeros, and those unobserved due to structural reasons such as syntactic constraints, structural zeros. We investigate the use of statistical t...
the 13c chemical shifts for a series of compounds which includes carboxylic acids, aldehydes, ethers, ketones and hydrocarbons were simulated by using the parametric techniques. the observed chemical shifts were related to numerically encoded structural parametes called descriptors. two new electronic descriptors were added to the previous descriptors. ploting of experimental versus calculated ...
BACKGROUND In the process of protein evolution, sequence variations within protein families can cause changes in protein structures and functions. However, structures tend to be more conserved than sequences and functions. This leads to an intriguing question: what is the evolutionary mechanism by which sequence variations produce structural changes? To investigate this question, we focused on ...
