Analysis of mouse lens morphological and proteomic abnormalities following depletion of βB3-crystallin.

Crystallin proteins serve as both essential structural and as well as protective components of the ocular lens and are required for the transparency and light refraction properties of the organ. The mouse lens crystallin proteome is represented by αA-, αB-, βA1-, βA2-, βA3-, βA4-, βB1-, βB2-, βB3-, γA-, γB-, γC-, γD-, γE, γF-, γN-, and γS-crystallin proteins encoded by 16 genes. Their mutations are responsible for lens opacification and early onset cataract formation.

Host metabolism balances microbial regulation of bile acid signalling.

Metabolites derived from the intestinal microbiota, including bile acids (BA), extensively modulate vertebrate physiology, including development, metabolism, immune responses and cognitive function. However, to what extent host responses balance the physiological effects of microbiota-derived metabolites remains unclear. Here, using untargeted metabolomics of mouse tissues, we identified a family of BA-methylcysteamine (BA-MCY) conjugates that are abundant in the intestine and dependent on vanin 1 (VNN1), a pantetheinase highly expressed in intestinal tissues.

Mid-infrared spectroscopy as a real-time diagnostic tool for chronic endometritis: A preliminary study.

Research Question: Can attenuated total reflection-Fourier transform infrared spectroscopy combined with machine learning techniques be used to develop a real-time diagnostic modality for chronic endometritis by analysing endometrial biopsies obtained during hysteroscopy?

Design: Women undergoing hysteroscopy for infertility assessment were enrolled in this prospective study from January 2020 to March 2021. Endometrial biopsies were evaluated using a spectrophotometer, and subsequently via histopathology, including immunohistochemical staining for the multiple myeloma oncogene-1 (MUM-1). Spectroscopy analyses of the positive and the negative chronic endometritis groups were compared across various cut-offs of MUM-1 positive cells per 10 high-power fields (HPF).

Sports after single-suture synostosis surgery: a survey of Synostosis Research Group members.

Objective: Patients with a history of surgery for single-suture craniosynostosis (SSC) as an infant often wish to participate in sports later in childhood. However, there are no established guidelines from neurosurgeons and craniofacial surgeons to guide parents in which sports their child should or should not participate. Therefore, this study aimed to evaluate the attitudes and practice patterns of experienced neurosurgeons and craniofacial surgeons regarding the counseling of caregivers of these patients about sports participation.
