Background: Upper gastrointestinal (GI) lesions are common in patients with chronic kidney disease and may contribute to anemia and increased morbidity, especially in patients on hemodialysis (HD). They become even more significant in patients undergoing kidney transplantation about to be subjected to lifelong immunosuppressive drugs.

Materials And Methods: This cross-sectional study conducted at Bangabandhu Sheikh Mujib Medical University's Departments of Gastroenterology and Nephrology analyzed 128 prospective kidney transplant patients following upper GI endoscopy.

Effective generation of U(IV) from U(VI) is a key step to achieve the partitioning of Pu from U in a spent nuclear fuel reprocessing plant. Reduction under a hydrogen atmosphere is one of the methods for the generation of U(IV) from U(VI) in the presence of a catalyst. Towards this, we have developed novel reduced graphene oxide (RGO)-supported Pt catalysts with varying RGO to Pt ratios.

Magnetically separable FeO-SiO/Pt catalysts with ~ 2% Pt loading have been developed for the generation of U(IV) in HNO-NH medium, used in the nuclear spent fuel reprocessing. Pt was impregnated in the catalysts via reductive heat treatment. The catalysts were characterized by x-ray diffraction, magnetization measurement, field emission scanning electron microscope and high-resolution transmission electron microscope studies.

Chronic hepatitis B virus (HBV) infection is a major cause of liver cirrhosis worldwide. While hepatic complications are well-documented, extra-hepatic manifestations such as secondary amyloidosis are less common and can lead to diverse and complex clinical outcomes. Here, we present the case of a 60-year-old male with a history of chronic hepatitis B who progressed to liver cirrhosis and presented with chronic, unexplained, intractable diarrhea unresponsive to standard treatments.

This report outlines the diagnostic journey of a 31-year-old female patient with chronic hepatitis B virus (HBV) infection who presented with acute rectal bleeding. Initially, she was misdiagnosed with ulcerative colitis at a primary care center, though the underlying cause of her symptoms was related to cirrhosis and its complication, portal hypertensive colopathy (PHC). At presentation, she revealed a history of ascites a few months before the onset of rectal bleeding, which had been managed with diuretics.

Objectives: Inflammatory bowel disease (IBD), comprising Crohn's disease and ulcerative colitis, significantly affects health-related quality of life (HRQOL). Despite the widespread use of the Short Form 12 version 2 (SF-12v2) questionnaire to assess HRQOL, its validity and reliability in Bengali IBD populations remain unclear. Our study aimed to evaluate the ability of the Bengali SF-12v2 to predict HRQOL in individuals with IBD.

Hyponatremia is an independent predictor of mortality in cirrhotic patients but little is known regarding the relationship between the level of serum sodium and 24-hour urinary sodium with the development of severity and complications of cirrhotic ascites. To observe the association of serum sodium and 24-hour urinary sodium levels with different grades of ascites and its complications in cirrhotic patients. In the department of Gastroenterology in a tertiary care hospital, this cross-sectional study was conducted from April 2019 to September 2020.

This study demonstrates the multiple carbon morphology forming abilities of two dissimilar polyion complex (PIC)-based double hydrophilic block copolymers (DHBC) along with three different phenol concentrations when subjecting the blend in aqueous media via a hydrothermal-assisted carbonization strategy. The morphological transition from worm-like to spherical along with granular is found for the blend of oppositely charged poly(ethylene glycol) (PEG)-conjugated poly(amino acid) block copolymers, PEG-poly(l-lysine) (PEG-PLys) and PEG-poly(glutamic acid) (PEG-PGlu), along with three different concentrations of phenol. In contrast, after mixing the combination of PEG-PLys and PEG-poly(aspartic acid) (PEG-PAsp) separately with three different phenol contents, elliptical to irregular to spherical structural transition occurred.

Introduction The importance of maintaining quality of life in managing inflammatory bowel disease (IBD) has increased in recent years. However, there is a lack of studies examining the health-related quality of life (HRQoL) of IBD patients in Bangladesh. Methodology This cross-sectional study was carried out in the IBD clinic, Bangabandhu Sheikh Mujib Medical University (BSMMU) from 2020 to 2022.

Nanocrystalline oxides are mainly responsible for Ni-base oxide dispersion strengthened (ODS) superalloys excellent thermo-mechanical properties. To establish the microstructural correlations between the metallic matrix and various oxide dispersoids, we report here the atomic-scale structure and chemistry of the complex nano-oxide dispersoids. Ultrahigh-resolution Cs-aberration-corrected scanning transmission electron microscopy (STEM) based techniques have been used to resolve nano-dispersoids in the Alloy 617 ODS.

Investigating the earliest stages of crystallization requires the transmission electron microscope (TEM) and is particularly challenging for materials which can be affected by the electron beam. Typically, when imaging at magnifications high enough to observe local crystallinity, the electron beam's current density must be high to produce adequate image contrast. Yet, minimizing the electron dose is necessary to reduce the changes caused by the beam.

Li-ion batteries function by Li intercalating into and through the layered electrode materials. Intercalation is a solid-state interaction resulting in the formation of new phases. The new observations presented here reveal that at the nanoscale the intercalation mechanism is fundamentally different from the existing models and is actually driven by nonuniform phase distributions rather than the localized Li concentration: the lithiation process is a 'distribution-dependent' phenomena.
