Silver nanoparticles (Ag NPs) exhibit antibacterial activity and are extensively used in numerous applications. The aim of this study was to examine the toxic effect of Ag NPs on the marine microalga, The microalgae, at the exponential growth phase, were treated with different concentrations of Ag NPs (50 and 100 nm) for 96 h. X-Ray diffraction (XRD) results indicated that the used NPs are single and pure Ag phase with a mean crystallite size of 21 and 32 nm.

Background: Little attention has been paid to neurotoxicants on the risk of dementia. Exposure to known neurotoxicants such as polychlorinated biphenyls (PCBs) and organochlorine (OC) pesticides is suspected to have adverse cognitive effects in older populations.
Objective: To assess whether plasma concentrations of PCBs and OC pesticides are associated with the risk of cognitive decline, Alzheimer's disease (AD) and of all-cause dementia in the Canadian older population.
Article Synopsis
- French Polynesia has the highest thyroid cancer incidence and mortality rates globally, potentially linked to high levels of non-essential trace elements (nETE) like mercury, lead, arsenic, and cadmium found in foods.
- The study involved 229 cases and 373 controls, analyzing food contamination and correlating it with nETE levels in fingernails among Polynesian participants.
- Results indicate that while lead and mercury were common pollutants in food and fingernail clippings, dietary exposure to nETE did not directly correlate with an increased risk of differentiated thyroid cancer, although certain factors like family cancer history influenced risks related to lead and arsenic intake.

Calcium (Ca) release from the endoplasmic reticulum plays an important role in many cell-fate defining cellular processes. Traditionally, this Ca release was associated with the ER Ca release channels, inositol 1,4,5‑triphosphate receptor (IPR) and ryanodine receptor (RyR). Lately, however, other calcium conductances have been found to be intracellularly localized and to participate in cell fate regulation.

In the present study, we aimed to analyse the effects of polyphenolic extracts from five types of Arctic berries in a model of diet-induced obesity.
Methods: Male C57BL/6 J mice were fed a high-fat/high-sucrose (HFHS) diet and orally treated with extracts of bog blueberry (BBE), cloudberry (CLE), crowberry (CRE), alpine bearberry (ABE), lingonberry (LGE) or vehicle (HFHS) for 8 weeks.
