Article Synopsis
  • The study investigates how prenatal exposure to endocrine disrupting chemicals (EDCs), specifically bisphenol A (BPA) and diethylhexyl phthalate (DEHP), affects the behavior of male and female rats.
  • Results show that female offspring exhibited reduced anxiety in certain behavioral tests, while males showed signs of feminization and maladaptive defensive behaviors, particularly with higher doses of DEHP.
  • The findings indicate that exposure to EDCs during pregnancy leads to sex-specific behavioral changes, altered corticosterone levels, and changes in adrenal gland weights, with varying effects based on dosage and chemical combinations.

Stem cells are a well-known autologous pluripotent cell source, having excellent potential to develop into specialized cells, such as brain, skin, and bone marrow cells. The oral cavity is reported to be a rich source of multiple types of oral stem cells, including the dental pulp, mucosal soft tissues, periodontal ligament, and apical papilla. Oral stem cells were useful for both the regeneration of soft tissue components in the dental pulp and mineralized structure regeneration, such as bone or dentin, and can be a viable substitute for traditionally used bone marrow stem cells.

Allium cepa (onion) and Allium sativum (garlic) are important members of the Amaryllidaceae (Alliaceae) family and are being used both as food and medicine for centuries in different parts of the world. Polysaccharides have been extracted from different parts of onion and garlic such as bulb, straw and cell wall. The current literature portrays several studies on the extraction of polysaccharides from onion and garlic, their modification and determination of their structural (molecular weight, monosaccharide unit and their arrangement, type and position of glycosidic bond or linkage, degree of polymerization, chain conformation) and functional properties (emulsifying property, moisture retention, hygroscopicity, thermal stability, foaming ability, fat-binding capacity).

  • Type 1 diabetes (T1D) leads to symptoms like increased hunger and high blood sugar levels, along with a stressed hormonal response.
  • Researchers tested whether injecting a gene therapy vector for leptin (a hormone that helps regulate hunger and energy) could improve these issues in diabetic rats.
  • Results showed that leptin gene therapy reduced blood sugar and some neuroendocrine dysfunctions in diabetic rats, but higher doses are needed for it to be a practical treatment for T1D.

Article Synopsis
  • Obesity is increasingly recognized as a global health issue, and high-fat intake may lead to increased levels of free fatty acids, impacting neuroendocrine functions related to obesity.
  • Researchers examined the effects of oleic acid on hypothalamic monoamines, proposing that it activates PPAR-α, a key factor in fatty acid metabolism, and that this effect would be diminished in rats with diet-induced obesity (DIO).
  • The study found that oleic acid significantly raised levels of norepinephrine, dopamine, and serotonin in a dose-dependent manner, but this response was reduced in DIO rats, indicating the importance of PPARα in the hypothalamus's response to fatty acids.

Article Synopsis
  • Diet-induced obese rats have altered stress (HPA) axis activity compared to diet-resistant rats, likely due to impaired leptin signaling.
  • Leptin injection increased serum leptin levels and reduced norepinephrine levels in both rat groups, suggesting that noradrenergic neurons respond to leptin, but responses in DIO rats' CRH and corticosterone varied with high-fat diet exposure.
  • DIO rats showed reduced leptin signaling in brainstem neurons and higher levels of free fatty acids and IL-1β, indicating neuroendocrine impairments that become more pronounced with prolonged high-fat diet exposure.

Article Synopsis
  • Type I Diabetes (T1D) leads to lower leptin levels and heightened stress response, as seen with increased norepinephrine (NE) in the hypothalamus.
  • In experiments with diabetic rats, leptin treatment reduced corticosterone levels significantly and showed a modest decrease in NE release.
  • The response of the hypothalamus to beta adrenergic agonists is altered in T1D, with only the alpha-2 adrenergic agonist clonidine effectively reversing leptin's impact on NE levels, while both agonists affected the corticosterone response.
