SARS-CoV-2 infection-induced immune thrombocytopenia in a patient with orthotopic heart transplantation: A case report and literature review.

Unlabelled: Immune thrombocytopenia (ITP) is an acquired autoimmune disorder characterized by low platelet counts with increased risk of bleeding. In particular, ITP induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been increasingly reported. Since immunosuppressive regimens in organ transplantation are often the primary cause of increased risk of infection, ITP following solid organ transplantation has occasionally been observed.

Robot-assisted laparoscopic hepatectomy for liver metastasis from clitoral malignant melanoma: a case report.

Introduction: Malignant melanomas occur most commonly in the skin, mucous membranes, or choroid. Clitoral malignant melanomas are extremely rare. Stage IV malignant melanomas have a poor prognosis, and molecularly targeted agents or immune checkpoint inhibitors are recommended.

Cage-Shaped Borate Catalysts Bearing Precisely Controlled Lewis Acidity and Their Application in Glycosylations.

Cage-shaped borates, whose Lewis acidity can be precisely modulated by the structural attributes of the triphenolic ligands, were employed as catalysts for glycosylation. Each cage-shaped borate displayed distinctive reactivity; thus, screening of the borate catalysts enabled controllable activation of glycosyl fluorides under mild conditions. Practical glycosylation was achieved by fine-tuning the Lewis acidity tailored to the substrate reactivity, thereby providing a versatile method applicable to the synthesis of complex glycans.

Clinical validation of preoperative serum markers for liver fibrosis in living donor liver transplantation recipients.

Purpose: To validate the reliability of fibrosis markers as predictors of graft survival in living donor liver transplantation (LDLT) recipients.

Methods: We reviewed data retrospectively, from 163 patients who underwent adult LDLT with preoperative measurements of type IV collagen (CIV), Mac-2 binding protein glycosylation isomer (M2BPGi), and hyaluronic acid (HA). Patients were divided into high and low groups for each biomarker, based on optimal cutoff values, and graft loss within 6 months was evaluated in each group.
