Sodiation of Enhanced Green Fluorescent Protein (EGFP) in Basic Solution Studied by Electrospray Mass Spectrometry.

In our previous work, the sodiation of melittin, cytochrome c, and ubiquitin in a 1 mM NaOH water/methanol solution was studied by electrospray mass spectrometry. It was suggested that the α-helix is more resistant to sodiation than the β-sheet. In this study, sodiation of enhanced green fluorescent protein (EGFP) composed of a β-barrel was studied in 1% CHCOOH (AcOH) or 1 mM NaOH water/methanol solution by electrospray mass spectrometry.

Method for long-term room temperature storage of mouse freeze-dried sperm.

Permanent preservation of genetic resources may be indispensable for the future of humanity. This requires liquid nitrogen, as is the case for preserving animal sperm. However, this technique is expensive and poses a risk of irrecoverable sample loss on non-replenishment of liquid nitrogen in case of natural disasters.

Successful pregnancy and live birth despite discontinuation of hormone replacement therapy at 3 weeks and 5 days of gestation following vitrified-warmed embryo transfer under a hormone replacement therapy cycle: a case report and literature review.

Background: In freeze-thawed embryo transfer (FET) cycles, hormone replacement treatment (HRT) is crucial for implantation and pregnancy maintenance. HRT typically continues until the 10th week of pregnancy owing to a luteoplacental shift, although a definitive HRT regimen remains undetermined. We present the case of a woman who underwent FET during an HRT cycle and ceased HRT after a negative pregnancy test at 3 weeks and 5 days, who went on to deliver a healthy baby.

Fast score is associated with patient-reported outcomes in patients with metabolic dysfunction-associated steatotic liver disease.

Backgrounds: People with metabolic dysfunction-associated steatotic liver disease (MASLD) frequently report fatigue. This symptom is associated with hepatic inflammation and fibrosis. FibroScan-aspartate aminotransferase (FAST) score is a noninvasive measurement tool that can be used to assess the severity of MASLD.
