AI Article Synopsis
- The study examined hepatic tissue from the coastline of Santa Catarina, Brazil, over a period from October 2016 to May 2018 to assess the distribution of essential and non-essential trace elements.
- Principal Component Analysis revealed that male and female adults showed different patterns of trace element bioaccumulation, while the Kruskal-Wallis test indicated variations based on sex and age.
- Heat maps effectively illustrated areas with high concentrations of trace elements and can be useful for understanding how local environments impact bioaccumulation in organisms.
Article Abstract
Hepatic tissue of sampled on the coastline of the state of Santa Catarina in Brazil between October 2016 and May 2018 was used to evaluate intraspecific trends and spatial distribution of essential trace elements (Mn, Co, Cu, Zn, Mo and Cr) and non-essential trace elements (As, Pb, Cd, Hg, Ba and V). Principal Component Analysis (PCA) indicated differences in the bioaccumulation of trace elements between female adults and male adults, differences to sex and age were indicated by Kruskal-Wallis test. Heat maps suggest hot spots in locals with high concentration of trace elements in liver of . In general, the concentration of trace elements were comparable with values reported in other studies carried out for this species in South America and other regions of the world. The heat maps showed to be a promising tool to identify influences of the locality on bioaccumulation of trace elements in .

Background: Photodynamic therapy (PDT) is a noninvasive cancer treatment that works by using light to stimulate the production of excessive cytotoxic reactive oxygen species (ROS), which effectively eliminates tumor cells. However, the therapeutic effects of PDT are often limited by tumor hypoxia, which prevents effective tumor cell elimination. The oxygen (O) consumption during PDT can further exacerbate hypoxia, leading to post-treatment adverse events.

Aim: To study the peculiarities of the ratio of the level of leptin and a number of toxic and essential chemical trace elements in biological environments in adolescent boys aged 13-14 years with obesity and delayed sexual development.
Materials And Methods: Three groups of adolescents aged 13-14 years were studied and formed: the main ones - with constitutional exogenous obesity of 1-2 degrees (1-20 boys without secondary signs of puberty; 2 - 24 boys with 2-4 stages of puberty according to Tanner) and comparisons (3 - 15 boys with normal body weight and without deviations in puberty).
Backgrounds And Aims: Type 2 diabetes and its complications are assumed to be major public health problems globally. Zinc is one of the elements that play a part in insulin secretion and signaling. Therefore, this study seeks the answer to the following question: "What are the effects of 220 mg zinc sulfate supplementation on the weight, blood pressure, and glycemic control of patients with Type 2 diabetes?".

Background: To date, there is no effective cure for the highly malignant brain tumor glioblastoma (GBM). GBM is the most common, aggressive central nervous system tumor (CNS). It commonly originates in glial cells such as microglia, oligodendroglia, astrocytes, or subpopulations of cancer stem cells (CSCs).

Introduction: Currently, trials are investigating the efficacy of nutrient-stimulated hormone-based therapies (NuSHs) in promoting weight loss in people living with overweight and obesity. However, the extent to which nutritional and functional outcomes are evaluated remains uncertain. Thus, we conducted a systematic mapping to assess the presence of nutritional and functional outcomes in randomized controlled trials (RCTs) investigating NuSHs.
