AI Article Synopsis
- The study looked at harmful chemicals called persistent organic pollutants (POPs) in loggerhead turtles found on the Turkish coast, focusing on differences between male and female turtles.
- Researchers tested 10 adult turtles (5 males and 5 females) after they passed away, examining different organs to see how much of these chemicals they contained.
- They found that both male and female turtles had the highest levels of these pollutants in their fat, and the turtles can be used to help track pollution in the environment.
Article Abstract
The study assessed persistent organic pollutants (POPs) in Caretta caretta turtles along Turkish coasts, analyzing bioaccumulation in accessible organs and discerning sex-related differences. Ten adult turtles (5 males, 5 females) from Mugla province were sampled post-mortem. Various tissues were analyzed for organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hydrocarbons (PAHs) using gas chromatography-mass spectrometry. DDT distribution showed no sex-based difference, with concentrations highest in fat tissue followed by liver, kidney, muscle, spleen, and heart. Male PCB concentrations ranked highest in fat, followed by kidney, liver, spleen, muscle, and heart, while females showed a similar trend. PAH concentrations were highest in fat for both sexes, followed by various organs. Limited PBDE concentrations hindered comprehensive evaluation. Overall, C. caretta act as effective bioindicators for monitoring environmental pollution, with certain POPs exhibiting sex and organ-based variations.

Background: Microglia play an important role in immune memory. Lipopolysaccharide (LPS) triggers immune memory and primes microglia, resulting in brain pathologies and brain dysfunction following a second stimulus (1, 2). An increase in the C1q/ PSD95 expressions within microglia and excessively synaptic pruning were observed in mouse model of Alzheimer's disease (3).

Background: Research into Alzheimer's Disease (AD) pathomechanisms frequently utilizes animal models with dominant mutations; however, the vast majority (>95%) of AD cases are idiopathic. Animal models with AD risk factors represent an approach with potentially greater translational validity. The predominant genetic risk factor for AD is the Apolipoprotein E ε4 (APOE4) polymorphism, with APOE4 homozygosity conferring approximately 15-fold higher risk relative to the normative APOE3/3 genotype.

Background: Excessive high-fat diet (HFD) consumption develops the obese pre-diabetic condition, which initiates neuroinflammation and numerous brain pathologies, resulting in cognitive decline (1). A cinnamamide derivative compound (2i-10) is recently identified as a novel myeloid differentiation factor 2 (MD-2) inhibitor, and has been shown to attenuate inflammation via toll-like receptor 4 (TLR4) signaling pathway (2). However, the effects of 2i-10 on the neuroinflammation, brain pathologies and cognitive function in the obese pre-diabetic rats have never been studied.
