Salivary steroids in acute central serous chorioretinopathy.
Int Ophthalmol
January 2025
University of Pittsburgh, UPMC Eye Center, 203 Lothrop Street, Pittsburgh, PA, 15213, USA.
Purpose: To analyze levels of salivary steroids, including 17-OH-progesterone (17-OHP), androstenedione, dehydroepiandrosterone, cortisol, cortisone, progesterone, testosterone, and estradiol, in patients with acute central serous chorioretinopathy (CSCR) patients.
Methods: Acute CSCR patients and healthy individuals were included in this observational case-control study. Levels of salivary steroids were determined by high-performance liquid chromatography with tandem mass spectrometry detection.
The usefulness of HbA1c measurement in diabetic mouse models using various devices.

Division of Diabetes and Endocrinology, Department of Internal Medicine, Kobe University Graduate School of Medicine.
In most cases, the diagnosis of diabetes in animal models is based solely on blood glucose levels. While hemoglobin A1c (HbA1c) is widely used in the diagnosis of diabetes in humans, it is rarely measured in mice in diabetes research. This is thought to be because there are no established reference values for mouse HbA1c, as well as the fact that there are very few reports on the variability and reproducibility of measurements taken using different devices.

In this study, we explored the efficacy and possible mechanisms in combination of CIMT and iTBS through behavioral evaluation, RNA sequencing, Golgi staining, transmission electronic microscope (TEM), high-performance liquid chromatography (HPLC), western blotting (WB) and immunofluorescence. Firstly, we observed that combination therapy is safe and effective, and it can significantly reduce the number of immature dendritic spines and increase the number of functional dendritic spines, the amount of glutamate (Glu) and the expression of Glu1 receptor (Glu1R).

Electronic address:
Apple polyphenols (APP) can reduce obesity. However, the effects of APP on abdominal subcutaneous adipose tissue (aSAT) at metabolic level were unclear. In this study, 5-week APP intervenes were conducted on 10-week high-fat diet (HFD) feeding mice with doses of 200 and 500 mg/kg b.

Conusvenoms are composed of peptides that are commonly post-translationally modified, increasing their chemical diversity beyond what is encoded in the genome and enhancing their potency and selectivity. This study describes how PTMs alter an α-conotoxin's selectivity for specific nAChR subtypes. Venom from the cone snailConus(Asprella)neocostatuswas fractionated using high-performance liquid chromatography and tested using a behavioral intracranial mouse bioassay and a cholinergic calcium imaging assay using SH-SY5Y neuroblastoma cells.
