Article Synopsis
- Chronic infections trigger the growth of neural progenitor cells (NPCs) in the brain, influenced by factors like inflammation and changes in cytokines.
- In a study with CD-1 adult male mice infected with the ME49 strain, researchers examined brain tissues to observe the proliferation of NPCs using immunofluorescence techniques and confocal microscopy.
- Findings revealed a significant increase in NPC proliferation in the infected mice compared to the control group, offering insights into the effects of chronic toxoplasmosis on brain cell dynamics.
Toxic Effects of Inhaled Vanadium Attached to Particulate Matter: A Literature Review.
Int J Environ Res Public Health
August 2021
Article Synopsis
- Environmental pollution, recognized as a major health risk by the World Health Organization, affects all income levels and highlights the dangers of suspended particulate matter, especially those containing vanadium emitted from fossil fuel combustion.
- The literature review focuses on the toxic effects of vanadium when inhaled, based on studies using a mouse model that reveal harmful impacts across various bodily systems.
- Research indicates vanadium exposure leads to serious health issues, including immunotoxicity and neurotoxicity, emphasizing the need for informed environmental policies to protect public health.
Phosphate metabolism was studied to determine whether polyphosphate (polyP) pools play a role in the enhanced resistance against Cd and metal-removal capacity of Cd-preadapted (CdPA) . Polyphosphate kinase (PPK), exopolyphosphatase (PPX) and phosphate transporter transcript levels and their activities increased in CdPA cells compared to control (Cnt) cells. K inhibited recombinant Ma-PPK and activated Ma-PPX, whereas divalent cations activated both enzymes.

Hintonia latiflora (Hl) is a tree native to the American continent belonging to the Rubiaceae family and its stem bark is empirically used mainly to treat diabetes and malaria; supplements containing Hl are sold in America and Europe without medical prescription, thus scientific information regarding its toxicity as a consequence of a regular consumption is needed. In the present study, the histopathological effect of 200 and 1000 mg/kg of HI methanolic stem bark extract (HlMeOHe) was evaluated in the small bowel, liver, pancreas, kidneys and brain of CD-1 male mice after oral sub-acute treatment for 28 days.

This work presents a novel option for the delivery of MSCs from human amniotic membrane (AM-hMSCs) that employs bovine bone matrix Nukbone (NKB) as a scaffold. Thus, the application of MSCs in repair and tissue regeneration processes depends principally on the efficient implementation of the techniques for placing these cells in a host tissue.
