Age-dependent pathogenic profiles of enterotoxigenic diarrhea in Bangladesh.

Background: Age plays a significant role in susceptibility to enterotoxigenic (ETEC) infections, yet the distribution of ETEC virulence factors across age groups remains understudied. This study investigated the differential pathogenic profiles ETEC across various age groups, emphasizing the importance of selecting potential ETEC antigens tailored to infection patterns in infants and adults in Bangladesh.

Methods: This study utilized the icddr,b's 2% systematic hospital surveillance data of diarrheal patients ( = 14,515) from 2017 to 2022 to examine the age-specific pathogenesis and clinical manifestations of ETEC infections.

Preparation and characterization of highly crystalline hydroxyapatite (HAp) from the scales of an anadromous fish (): a comparative study with the freshwater fish scale () derived HAp.

Waste generation from fish processing sectors has become a significant environmental concern. This issue is exacerbated in countries with high aquaculture production and inefficient fish scale (FS) utilization. This study prepared and compared highly crystalline hydroxyapatite (HAp) from the FS of an anadromous fish, (I-HAp), and a freshwater fish, (R-HAp).

Coinfection and Clinical Impact of Enterotoxigenic Escherichia coli Harboring Diverse Toxin Variants and Colonization Factors: 2017-2022.

Objectives: The severity of the diarrhea disease is exacerbated by co-infections that involve Enterotoxigenic Escherichia coli (ETEC) and other enteric pathogens, which complicate the diagnosis and treatment. This study explores the prevalence, clinical manifestations, and risk factors of ETEC and its co-infections in Dhaka, Bangladesh.

Methods: The study used data from the Diarrheal Disease Surveillance System at Dhaka Hospital, involving 16,276 patients from 2017-2022.

Combined experimental and first principles look into (Ce, Mo) doped BiVO.

Here we investigated the effects of Ce and Mo doping on hydrothermally synthesized bismuth vanadate BiVO nanoparticles (NPs). The existence of monoclinic scheelite and tetragonal zircon phases of NPs was validated from Rietveld refinement of the powdered X-ray diffraction, room temperature Raman, and Fourier-transform infrared spectroscopy. The co-doping of Bi and V sites with respective Ce and Mo dopants in a mixed tetragonal zircon and monoclinic scheelite phases of BiVO lattice was corroborated from high-resolution transmission electron microscopy and X-ray photoelectron spectroscopy.

The role of urine metabolomics in the diagnosis and management of adult and pediatric Crohn's disease and ulcerative colitis.

Introduction: Urine metabolomics offers a non-invasive approach to diagnose and manage inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), by identifying distinct metabolic signatures.

Objectives: This narrative review summarizes current findings on urinary metabolites in IBD, evaluating their roles in disease differentiation, assessment of activity, and monitoring therapeutic response.

Methods: A comprehensive literature search of PubMed and MEDLINE up to October 2023 was conducted using keywords, such as 'urine metabolomics', 'inflammatory bowel disease', 'Crohn's disease', 'ulcerative colitis', and 'urinary biomarkers'.
