BACKGROUND: Infection with the Hepatitis B virus (HBV) continues to be one of the leading healthcare issues in Pakistan, affecting over 6 million people. The existence of HBsAg mutants is well documented in many countries. In Pakistan, HBV screening in the majority of the blood banks is performed by Rapid Detection Devices or ELISA tests. These tests are designed to detect HBsAg, but may not detect the mutant HBsAg. Failure to detect the HBsAg mutant may result in the transmission of HBV infection from donor to recipient...

Several studies have reported that metformin is cardioprotective for diabetic and non-diabetic ischemic hearts through mechanisms that cannot be entirely attributed to its anti-hyperglycemic effect. This study was designed to investigate the cardioprotective effects of metformin with and without vitamin E after induction myocardial infarction (MI) in rats, using isoproterenol. Administration of metformin or vitamin E significantly reduced the cardiac mass index (P<0.01), ameliorated the changes to cardiac biomarkers, and attenuated oxidative stress levels compared to the isoproterenol group...

α-Amylase is one of the important enzymes in the starch-processing industry. However, starch processing requires high temperature, thus resulting in high cost. The high adsorptivity of α-amylase to the substrate allows this enzyme to digest the starch at a lower temperature. α-Amylase from Saccharomycopsis fibuligera R64 (Sfamy R64), a locally sourced enzyme from Indonesia, has a high amylolytic activity but low starch adsorptivity. The objective of this study was to design a computational model of Sfamy R64 with increased starch adsorptivity using bioinformatics method...

Background and Objectives: The self-expandable metal stent (SEMS) is an alternative for several possible surgical and palliative treatments of upper gastrointestinal obstructions that occur in several disease states. The present study was performed to describe a single-center experience with upper gastrointestinal stents. Methods: All patients at a single center who had an SEMS placed for the treatment of obstruction over a 3-year period were retrospectively evaluated...

OBJECTIVES: In our laboratory we evaluated the use of micro-computed tomography (micro-CT) using a high resolution acquisition protocol and fetuses obtained on Gestation Day (GD) 29 (mating = GD 0). METHODS: To show concordance between traditional Alizarin Red S stain and micro-CT skeletal examination methods, 103 fetuses from 19 untreated Dutch belted rabbits were obtained by cesarean section and stored frozen. The fetuses were thawed, imaged and examined digitally by micro-CT, then stained and re-examined using traditional methods...

The current study comprises of an inclusive biophysical study, enlightening the binding of L-3, 4-dihydroxyphenylalanine (L-Dopa) with human lysozyme (HL) and hen egg white lysozyme (HEWL). Spectroscopic and molecular docking tools have been utilized to study the interaction of L-Dopa with both HL and HEWL. Spectrofluorimetric measurements exhibited that L-Dopa quenched the HL and HEWL intrinsic fluorescence. A binding constant (Kb) of ∼10(4)M(-1) for both HL and HEWL was obtained, asserting a significant binding...

In the United States alone, 1.6 to 3.8 million people have sports-related concussions yearly. The patho-mechanisms of concussions may not be directly measured by conventional neuroimaging; advanced models may be needed to address the shortcomings of the current clinical protocols. Multimodal advanced imaging may provide more accurate diagnosis and predict the clinical course of concussion, assessing the efficacy of existing and emerging multifaceted therapies. In this article, the authors present an overview and pictorial display of conventional and advanced multimodal MR imaging methods that have been applied to identify the brain structures affected in traumatic brain injuries...

Background/aim: A number of tumor markers detected in the serum or pathological specimens using immunohistochemical methods are used for early detection of malignancies and postoperative follow-up. Human leukocyte antigen-G (HLA-G) is a nonclassic HLA class I molecule. Recent studies suggested a relationship between HLA-G positivity and the stage or the phenotype of the malignancy. In this study, the relationship between serum HLA-G positivity and thyroid cancer was investigated. Materials and methods: Fifty patients with thyroid cancer and 45 healthy volunteers were included in this study...

Background/aim: Immunogenicity and safety of a primary series of a fully liquid, hexavalent DTaP-IPV-HB-PRP-T vaccine given at 2, 3, and 4 months of age compared to licensed comparators and a DTaP-IPV-HB-PRP-T booster at 15?18 months were evaluated. Materials and methods: This was a Phase III, randomized, open-label trial. Primary series (no hepatitis B [HB] at birth) of DTaP-IPV-HB-PRP-T (N = 155) (group 1) or licensed control vaccines (DTaP-IPV//PRP-T and standalone HB: N = 155) (group 2) and DTaP-IPV-HB-PRP-T booster were administered...

Background/aim: It is recommended that a central venous catheter (CVC) be removed if central line-associated bloodstream infection (CLABSI) has been diagnosed. The objective of this retrospective study was to evaluate the risk factors for recurrent CLABSI in reinserted catheters in a pediatric intensive care unit. Materials and methods: Patients with recurrent and nonrecurrent CLABSI were compared in terms of the catheter exchange interval, the interval between negative blood culture and reinsertion of the CVC, and the pre-/reinsertion treatment duration...

Autologous hematopoietic cell transplantation (AHCT) is an established treatment option for adult patients presenting with multiple myeloma (MM), Hodgkin lymphoma (HL) and various subtypes of non-Hodgkin lymphoma (NHL) in upfront and/or relapsed/refractory disease settings. Although there are recently published consensus guidelines addressing critical issues regarding autologous hematopoietic progenitor cell mobilization (HPCM), mobilization strategies of transplant centers show high variability in terms of routine practice...

Background: The purpose of the present study was to assess the validity of continuous metabolic syndrome score (cMetS) for predicting metabolic syndrome (MetS) and to determine the cutoff values in a representative sample of Iranian children and adolescents. Methods: This national study was conducted among 3843 students, aged 7-18 years country during the fifth survey of a national school-based surveillance program. The cMetS was computed by standardizing the residuals of waist circumference, mean arterial blood pressure, high-density lipoprotein cholesterol, triglycerides, and glucose by regressing them according to age and sex and aggregating them...
