Background: The increased apoptosis of bile duct epithelial cells (BECs) due to some damage factors is considered the initiating factor in the occurrence and progression of biliary atresia (BA). Vitamin D receptor (VDR) is thought to play a crucial role in maintaining the intrinsic immune balance and integrity of bile duct epithelial cells (BECs). To investigate the role of VDRs in the pathogenesis and progression of BA using in vitro and in vivo models.

Ovarian granulosa cells produce a variety of biologically active compounds in addition to steroid hormones that include numerous families of growth factors, cytokines and adipokines. Many of these function as endocrine, paracrine and autocrine hormones to regulate ovarian activity. The goal of this review is to provide an update on the evidence in domestic animals on how FSH, insulin and IGF1 regulate the function of granulosa cells with a focus on ovarian steroidogenesis and cell proliferation with comparisons across six domestic animals: pigs, cattle, horses, water buffalo, goats and sheep.

Annular atrophic lichen planus (AALP) is a chronic subtype of lichen planus that classically does not respond to treatment with topical steroids. An inflammatory reaction in the dermal infiltrate may play a role in the development of AALP, but the exact pathogenesis remains unclear. We present the case of a 54-year-old-female with lesions on her trunk and extremities that developed following vaccination.

Objective: We sought to determine the safety and efficacy of the oral progesterone antagonist onapristone in combination with anastrozole in patients with recurrent progesterone receptor-positive adult-type granulosa cell tumor of the ovary.

Methods: This was a single-institution phase II study of patients with progesterone receptor-positive adult-type granulosa cell tumor who received at least 1 prior line of chemotherapy. Patients were enrolled from November 2021 to August 2022 and tissue was evaluated for progesterone receptor status via immunohistochemistry.

This case report describes a 70-year-old male presenting with limb weakness, urinary retention and tandem cervical and lumbar spinal stenosis with complicating white cord syndrome, a rare reperfusion injury post decompression surgery. Initially admitted following an unwitnessed fall, the patient's neurological examination indicated that progressive weakness of the limbs and sensory loss etiology is cervical and lumbar spondylosis with severe spinal canal stenosis, confirmed by imaging. Due to rapid deterioration, he underwent C5 corpectomy, cervical decompression and fusion.
