Article Synopsis
  • High levels of follicle-stimulating hormone (FSH) in post-menopausal women are linked to the development of Alzheimer's disease (AD), as shown by studies in mice.
  • Mice lacking FSH receptors displayed improved spatial memory, indicating that blocking FSH signaling can help prevent memory loss related to aging and AD-like pathology.
  • The findings suggest that targeting FSH could be a potential strategy for preventing memory deficits in post-menopausal women.

Article Synopsis
  • Alzheimer's disease (AD) is linked to high levels of follicle-stimulating hormone (FSH) in post-menopausal women, which may trigger memory loss and AD-like symptoms in mice.
  • A study tested different groups of female mice (some unoperated, some with surgery, and some undergoing ovariectomy) and found that gene-deletion of FSH receptor (Fshr) improved spatial memory and recognized memory, highlighting a gene-dose effect.
  • Overall, the research suggests that lower FSH levels could have protective benefits against memory loss associated with aging and AD, as indicated by better memory retention in mice with reduced FSH signaling.

During pediatric liver transplant, biliary reconstruction is often performed using Roux-en-Y choledoc-hojejunostomy or hepaticojejunostomy due to size mismatch, excessive tension caused by distance between donor and recipient ducts, or for transplant to treat primary biliary pathology. This method can be associated with additional small bowel-related complications compared with end-to-end ductal anastomosis. We report a case of late small bowel obstruction secondary to an impacted bezoar that formed at a patulous jejunojejunostomy portion of the biliary-enteric anastomosis.

Article Synopsis
  • Clinical studies suggest that luteinizing hormone (LH), typically known for its role in fertility, may also influence cognitive decline and mood disorders in aging, particularly in post-menopausal women.
  • The study utilized various behavioral tests on 12-month-old mice lacking LH signaling to explore its impact on cognitive and emotional behaviors, revealing that these mice did not show the anxiety seen in wild type mice.
  • The findings indicate that loss of LH signaling can reverse certain age-related emotional issues, potentially paving the way for future treatments targeting LH activity.

OLT is known to be associated with a precarious perioperative hemostatic state due to dysregulation of procoagulant and anticoagulant factors, endothelial injury, and inflammation. Transmission of inherited bleeding and clotting disorders from the liver donor to the recipient may further complicate hemostasis during and after transplantation. As a result, consideration of congenital coagulation disorders in the liver donor is a practical concern for donor selection.

Article Synopsis
  • Seasonal changes in food intake and body fat in animals are influenced by changes in light duration, regulated by melatonin from the pineal gland.
  • The mediobasal hypothalamus plays a key role in integrating these seasonal variations through the detection of the thyroid-stimulating hormone (TSH).
  • Tanycytes in the hypothalamus are involved in regulating energy balance and modulating the blood-hypothalamus barrier, with TSH having potential effects beyond traditional single-target actions.

Article Synopsis
  • * The research identified optimal buffer conditions (pH 5.62 with phosphate and pH 6.85 with histidine) and determined that lower salt concentrations improved stability by reducing hydrophobic interactions.
  • * Among stabilizers, Tween 20 and sugars like trehalose and sucrose enhanced thermal stability, leading to a final formulation that showed increased stability, but further research is needed to assess stability at higher concentrations.

The dry deposition process refers to the flux loss of an atmospheric pollutant due to uptake of the pollutant by the earth's surfaces. Dry deposition flux of a chemical species is typically calculated as the product of its surface-layer concentration and its dry deposition velocity (V). Field measurement based V data are very scarce or do not exist for many chemical species considered in chemistry transport models.

Mutations in the gene NR0B1 have been associated with several clinical phenotypes of X-linked adrenal hypoplasia congenita (AHC). The degree and onset of adrenal insufficiency and involvement of hypogonadotropic hypogonadism is variable and may not be concordant with the identified mutation. We review a patient with AHC in which prenatal estriol levels were low, presenting with early-onset mineralocorticoid deficiency in the newborn period followed by glucocorticoid deficiency 2 years later.

The aerosol indirect effect remains the most uncertain aspect of climate change modeling, calling for characterization of individual particles sizes and compositions with high spatial and temporal resolution. We present the first deployment of our single particle mass spectrometer (SPLAT II) operated in dual data acquisition mode to simultaneously measure particle number concentrations, density, asphericity, and individual particle size and quantitative composition, with temporal resolution better than 60 s, thus yielding all the required properties to definitively characterize the aerosol-cloud interaction in this exemplary case. We find that particles are composed of oxygenated organics, many mixed with sulfates, biomass burning particles, some with sulfates, and processed sea-salt.
