The aim of this study was to introduce an interventional heart catheterization to close patent ductus arteriosus (PDA), ventricular septal defect (VSD), atrial septal defect (ASD), and pulmonary hypertension without complications from open heart surgery and a 3-day hospitalization period. PDA, VSD, and ASD are among the most common abnormalities associated with various complications. This case is a 3.

Background: In April 2020, an association between multisystem inflammatory syndromes (MIS-C) was observed in children with severe acute respiratory syndrome coronavirus infection (SARS-CoV-2). Most patients had heart involvement alone, and most patients had pericardial effusion. This study aimed to express and emphasize cardiac involvement in pediatric patients with respiratory symptoms who were diagnosed with COVID-19.

In recent years, microfluidic-based particle/cell manipulation techniques have catalyzed significant advances in several fields of science. As an efficient, precise, and label-free particle/cell manipulation technique, dielectrophoresis (DEP) has recently attracted widespread attention. This paper presents the design and investigation of a straight sheathless 3D microchannel with a wall-mounted trapezoidal obstacle for continuous-flow separation of three different populations of polystyrene (PS) particles (5, 10 and 20 µm) using DEP.

Article Synopsis
  • A new microfluidic device with a bi-gap electrode pair is introduced, capable of effectively separating three sizes of polystyrene particles via dielectrophoresis.
  • The device uses a solver developed in OpenFOAM to optimize parameters like flow rate and electrode angles for better particle separation efficiency.
  • Experimental results showed that the device can achieve over 99% purity in separating particles at a flow rate of 100 μL/h using a 20 V electric potential, making it a practical solution for continuous separation of particle populations in mixtures.

Article Synopsis
  • HAM/TSP is a neurodegenerative disease caused by interactions with the HTLV-1 virus, and this study examined the effects of vitamin D and lipid profiles on patients.
  • The research found that HAM/TSP patients had higher levels of triglycerides and LDL cholesterol and lower levels of HDL cholesterol and vitamin D compared to healthy subjects.
  • Significant correlations were identified between viral load and cholesterol levels, as well as other lipids in HAM/TSP patients, suggesting that addressing lipid imbalances and vitamin D deficiency could help manage this condition.

Background: Recent evidence has demonstrated that environment and genetic factors play pivotal roles in diabetes and its related complications. The significant contributory role of cytokines in pathogenesis of type 2 diabetes is also well documented. This study was aimed to examine and compare both CXCL1 (GRO-alpha) and CXCL10 (IP-10) circulating levels in type 2 diabetic patients and healthy controls.

Several environmental and genetic factors are believed to influence the onset of diabetes and its complications. It has also been established that cytokines play a key role in the pathogenesis of type 2 diabetes. Previous studies have revealed that the polymorphism at the stromal-derived factor 1β (SDF-1β) 3'A regulates the expression of SDF-1 (CXCL12).

The impact of several environmental and genetic factors on diabetes and its complications is well documented. It has also been established that cytokines play a key role in the regulation of immune responses which have been shown to be important in the pathogenesis of diabetes. Studies showed that single-nucleotide polymorphisms within the -592 region of interleukin-10 (IL-10) are associated with the regulation of its expression.

Background: Chemokines and their receptors are clinically important mediators, as the chemokine receptors are expressed on almost all immune cells. They play pivotal roles in pathogenesis of almost all clinical situations including asthma. Correspondingly, MIP-1α (CCL3), MIP-1β (CCL4), and RANTES (CCL5) are among the important chemokines involved in the pathogenesis of asthma.

Objective: Adiponectin gene polymorphisms are associated with obesity, metabolic syndrome and type 2 diabetes (T2D). The study evaluated possible associations of +45T/G and -11391G/A adiponectin gene polymorphisms with body mass index (BMI), waist circumferences (WC), and blood pressure in diabetic and non-diabetic Iranians.

Methods: This cross-sectional study involved two groups of subjects: 243 diabetic patients and 173 non-diabetic subjects recruited from Rafsanjan city in the south-east of Iran.

Thalassemia and hemodialysis patients are at risk of blood-transmitted infections due to their long-term need for blood transfusion. Nowadays, control of viral infections, including HCV infections, is one of the main tasks of blood transfusion services worldwide. Therefore, the aim of this research was to investigate the prevalence of HCV infection in thalassemia and hemodialysis patients in Kerman, in southeastern Iran.

The impact of several environmental and genetic factors on diabetes and its complications is well documented. The present study was aimed to examine the serum levels of IL-17A and IFN-gamma as antagonistic cytokines in nephropathic and non-nephropathic type-2 diabetic patients. In this experimental study, serum samples were obtained from 180 type-2 diabetic patients, 100 nephropathic type-2 diabetic patients and 100 healthy controls.
