The aim of the study was to compare bone lead concentrations in cortical and trabecular bones in long-term exposed primary copper and lead smelter workers, and to relate the measured concentrations to the previous lead exposure of the workers. Lead concentrations in seven bones (trabecular: sternum, vertebrae, iliac crest, rib; cortical: femur, left forefinger, and temporal bone) were determined by electrothermal atomic absorption spectrometry in 32 male, long-term exposed copper and lead smelter workers, and compared with levels in 10 male occupationally unexposed reference persons. A time-integrated blood lead index (cumulative blood lead index, CBLI) was calculated for each worker. The lead levels in the seven studied bones were all significantly higher in active and retired lead workers as compared with the reference group (p

The Southeastern part of the Bay of Bengal is increasingly threatened by heavy metal pollution, posing significant risks to both aquatic life and human health. In this context, the contamination levels of six heavy metals-Cadmium (Cd), Lead (Pb), Zinc (Zn), Copper (Cu), Manganese (Mn), and Iron (Fe)-were assessed in the soft tissues of Green mussels (Perna viridis) from five key sites: Matamuhuri, Moheshkhali, Bakhkhali, Naf, and St. Martin.

The self-assembly of phenylalanine (F)-based peptides is a critical area of research with potential implications for the development of advanced biomaterials and technologies. Previous studies indicate that homo-oligopeptides with F-X residues (X = 1 to 6) can self-assemble into diverse nano-microstructures, but the role of oligopeptide chain length on this process remains unclear. This review investigates the role of F-X chain length on self-assembly processes and morphologies, considering the effect of incubation conditions and the capping group at the N and/or C terminals.

Due to a lack of high-quality water, farmers have been compelled to use sewage water for irrigation, contaminating agricultural soils with multiple heavy metals. For the remediation of contaminated soil, plant growth-promoting rhizobacteria (PGPR), pressmud (PM), and iron (III) oxide were used to improve the growth and phytostabilization potential of chickpea grown in contaminated soil. Contaminated soil was collected from a nearby field, receiving sewage and factory water over the last 60 years.

: In oral and oropharyngeal squamous cell carcinoma (OSCC, OPSCC), frequent inadequate surgical margins highlight the importance of precise intraoperative identification and delineation of cancerous tissue for improving patient outcomes. : A prospective, open-label, single-center, single dose, exploratory phase II clinical trial (EudraCT 2022-001361-12) to assess the efficacy of the novel uPAR-targeting near-infrared imaging agent, FG001, for intraoperative detection of OSCC and OPSCC. Macroscopic tumor detection was quantified with sensitivity and intraoperative tumor-to-background ratio (TBR).

Excessive exercise can lead to fatigue, consequently affect exercise performance, and further have an adverse impact to human health. The synergistic effects of ginsenosides, salidroside, and syringin on improving exercise performance remain unknown. Hence, the effects of Chinese herb powder (CHP) which consisted of bioactive compounds such as ginsenosides (Rg1, Re, and Rb1), salidroside, and syringin on exercise performance, energy metabolism, tissue damage, antioxidant activity, and inflammatory cytokine were investigated in exhaustive exercise rats.
