Structural modification of defective WO by g-CN for photocatalytic gold recovery from non-cyanide-based plating effluent.

A set of nCN/WO composites was synthesized through a simple thermal treatment for gold recovery from the simulated effluent of a non-cyanide-based plating bath. The obtained results exhibited that all nCN/WO composites demonstrated a higher photocatalytic activity for gold recovery than their pristine components due to the formation of nanocomposites which paved a convenient pathway for charge transfer. Among all synthesized composites, the 5.

Isolated Prostate Tuberculosis Mimicking Prostate Cancer.

Background: Tuberculosis (TB) remains the deadliest infectious disease globally, with the kidneys being the most frequently affected organ in the genitourinary system. Isolated prostate involvement by tuberculosis is rare and may mimic prostate cancer. This case report aims to highlight the diagnostic challenges and therapeutic responses associated with isolated prostate tuberculosis, particularly in the context of significantly elevated prostate-specific antigen (PSA) levels in a TB-endemic region.

Antibiotic Resistance, and Biofilm Forming Characteristics of Escherichia coli Clinical Isolates at a Hospital in Tigray, Northern Ethiopia.

Background:  infections are becoming difficult to treat due to the bacterium's biofilm-forming capabilities and rising resistance to multiple antibiotics, posing a growing clinical challenge. This study assessed the antimicrobial resistance and biofilm formation by isolates from patients at a hospital in Tigray, Northern Ethiopia.

Method: From patients exhibiting signs of bacterial infection, while excluding recent antibiotic users or those with incomplete data, 417 clinical samples comprised of 84 blood, 108 pus, and 225 urine samples were obtained in a cross-sectional study.

Under-five mortality during the war in Tigray: A community-based study.

Background: Child mortality is one of the key indicators of the Sustainable development goals. The Ethiopian healthcare system in general and Tigray's healthcare system in particular has shown a remarkable progress in terms of reducing maternal, neonatal, and under-five mortality in the last couple of decades. However, the war erupted in November 2020 caused the healthcare system to collapse and little is known about the status of child mortality in Tigray.

Delivery of small hydrophilic molecules across the stratum corneum: Identification of model systems and parameters to study topical delivery of free amino acids.

Free amino acids (FAAs) constitute the largest component (∼40 %) of the so-called natural moisturizing factors of the skin. Their level declines in dry skin conditions and one strategy to overcome this problem may involve the topical delivery of FAAs through appropriate strategy. The objective of the present study was therefore to identify alternative skin models and study the corneocyte-water partition coefficients (K) and permeation coefficient (K) of 18 FAAs.
