S-ketamine alleviates depression-like behavior and hippocampal neuroplasticity in the offspring of mice that experience prenatal stress.

Prenatal stress exerts long-term impact on neurodevelopment in the offspring, with consequences such as increasing the offspring's risk of depression in adolescence and early adulthood. S-ketamine can produce rapid and robust antidepressant effects, but it is not clear yet whether and how S-ketamine alleviates depression in prenatally stressed offspring. The current study incestigated the preliminary anti-depression mechanism of S-ketamine in prenatally stressed offspring, particularly with regard to neuroplasticity.

ARSCP: An antimicrobial residue surveillance cloud platform for animal-derived foods.

Antibiotics have been widely used for improving human and animal health and well-being for many decades. However, the enormous antibiotic usage in agriculture especially for livestock leads to considerable quantities of antibiotic residues in associated food products and can reach potentially hazardous levels for consumers. Therefore, timely detection and systematical surveillance on residual antibiotics in food materials are of significance to minimize the negative impact caused by such unwanted antibiotic leftovers.

Adenosquamous carcinoma of the upper aerodigestive tract: a clinicopathologic study of 12 cases and review of the literature.

Purpose: Adenosquamous carcinoma is an uncommon, controversial neoplasm. To further comprehend its natural history, the clinical and pathological features of 12 new cases were reviewed and analyzed collectively with those described in the English literature.

Materials And Methods: Twelve cases of adenosquamous carcinoma of the upper aerodigestive tract with adequate follow-up and available microscopic slides and paraffin tissue blocks were identified in the anatomic pathology files of Presbyterian Hospital of the University of Pittsburgh Medical Center over the period 1983-2001.
