Feasibility and efficacy of an early sensory-motor rehabilitation program on hand function in patients with stroke: a pilot, single-subject experimental design.

Objective: Hand and upper limb functional impairments following stroke lead to limitations in performing activities of daily living. We aimed to investigate feasibility and efficacy of an early sensory-motor rehabilitation program on hand and upper limb function in patients with acute stroke.

Design: A pilot, single-subject experimental, A-B-A study.

Susceptibility and Severity of COVID-19 Are Both Associated With Lower Overall Viral-Peptide Binding Repertoire of HLA Class I Molecules, Especially in Younger People.

An important number of studies have been conducted on the potential association between human leukocyte antigen () genes and COVID-19 susceptibility and severity since the beginning of the pandemic. However, case-control and peptide-binding prediction methods tended to provide inconsistent conclusions on risk and protective alleles, whereas some researchers suggested the importance of considering the overall capacity of an individual's HLA Class I molecules to present SARS-CoV-2-derived peptides. To close the gap between these approaches, we explored the distributions of , , , and 1st-field alleles in 142 Iranian patients with COVID-19 and 143 ethnically matched healthy controls, and applied predictions of bound viral peptides for each individual's HLA molecules.

Association between iron deposition in splenic,hepatic and myocardial tissues assessed by T2* relaxometry technique.

Background: Decreasing signal intensity of the spleen assessed by T2* MRI is a frequent finding in patients with beta-thalassemia due to iron deposition within the reticuloendothelial cells in this organ. This parameter can also be applied to determine the candidates for blood cell transfusion. However, the association between splenic siderosis and iron overload in other vital organs such as heart and liver remains unclear.

A retrospective cohort of coronary artery disease development after at least two angiograms in patients with normal coronary angiograms or mild coronary artery disease.

Background: Coronary Artery Disease is one of the leading causes of death in the world. CAD usually progresses slowly during time and patients with normal or near-normal coronary arteries are also at risk of developing CAD. It is now believed that even mild atherosclerosis can increase the rate of CAD.

Phytotoxic Potential and Phenolic Profile of Extracts from .

A large number of plants produce secondary metabolites known as allelochemicals that are capable of inhibiting the germination of competitive species. This process is known as allelopathy and is mediated by several classes of chemicals, among which phenolic compounds are the most frequent. Thus, plant allelochemicals can be used to control weeds in agricultural systems.

Challenging case of muscle bridge; a 15-year follow-up of a patient.

Background: Anatomically myocardial bridging (MB) consists of either superficial myocardial fibers that traverse over the LAD or deep fibers that encircle the coronary artery. In this study, we present a patient with myocardial bridging, who was primarily diagnosed with coronary artery disease which did not properly respond to full-dose medical treatment but benefited from coronary artery bypass graft (CABG).

Case Presentation: In 2017, a 53-year old man was referred to Tehran Heart Center (THC) with complaint of typical chest pain (TCP).

Measuring the reliability of sagittal facial anthropometric measurements under soft tissue displacement using a modified ruler.

Objective: Despite the current use of radiography for quantifying sagittal skeletal measurements, it is an unsuitable way for screening or epidemiologic purposes. Although not fully approved, anthropometric measurements have been suggested as a substitute, and considering displacement of soft tissues, could possibly lead to more consistent results. The purpose of this study was to evaluate the reliability of anthropometric anteroposterior facial measurements under soft tissue compression using a special ruler.
