Background: Ovarian tissue cryopreservation and transplantation (OTCT) is a promising approach for fertility preservation. However, significant follicle loss after transplantation challenges long-term reproductive recovery. Although primordial follicle loss and ischemic damage are known contributors, the underlying mechanisms and effective strategies to mitigate these damages are still lacking.

However, our understanding of epigenetic dynamics during preimplantation development at single-cell resolution remains incomplete. Here, we developed scNanoATAC-seq2, a single-cell assay for transposase-accessible chromatin using long-read sequencing for scarce samples.

Despite its prevalence, the underlying mechanisms of VC remain unclear. In this study, we aimed to investigate whether and how Otubain-2 (OTUB2) contributes to VC.
View Article and Find Full Text PDFOvarian function declines significantly as females enter middle-age, but the mechanisms underlying this decline remain unclear. Here, we utilize whole-organ imaging to observe a notable decrease in ovarian blood vessel (oBV) density and angiogenesis intensity of middle-aged mice. This leads to a diminished blood supply to the ovaries, resulting in inadequate development and maturation of ovarian follicles.

Background: The prevalence of vascular calcification (VC) in chronic kidney disease (CKD) patients remains substantial, but currently, there are no effective pharmaceutical therapies available. BRCA1/BRCA2-containing complex subunit 36 (BRCC36) has been implicated in osteoblast osteogenic conversion; however, its specific role in VC remains to be fully elucidated. The aim of this study was to investigate the role and underlying mechanisms of BRCC36 in VC.

However, its pathophysiology remains unclear. Utilizing high-precision single-cell RNA sequencing, we profile the normal, eutopic, and ectopic endometrium from 34 individuals across proliferative and secretory phases.

We present a case study of one patient with nephrotic syndrome and membranous nephropathy, who underwent treatment with prednisone and cyclosporine in 2016. In early 2017, the patient was diagnosed with a "fungal infection" and discontinued the use of cyclosporine.

Ovarian mesenchymal cells (oMCs) constitute a distinct microenvironment that supports folliculogenesis under physiological conditions. Supplementation of exogenous non-ovarian mesenchymal-related cells has been reported to be an efficient approach to improve ovarian functions. However, the development and cellular and molecular characteristics of endogenous oMCs remain largely unexplored.

Currently, there are no standardized guidelines for this disease. Recent studies have recognized a high prevalence of thrombophilias and hypercoagulable conditions in calciphylaxis patients.
View Article and Find Full Text PDFOvarian follicle is the basic functional unit of female reproduction, and is composed of oocyte and surrounding granulosa cells. In mammals, folliculogenesis strictly rely on gonadotropin regulations to determine the ovulation and the quality of eggs. However, the dynamic changes of protein-expressing profiles in follicles at different developmental stages remain largely unknown.

Purpose: Immune checkpoint inhibitor (ICI) therapy is now the stand of care for lung cancer. Due to the low incidence, the study of acute kidney injury (AKI) in lung cancer patients treated with ICIs was hardly reported. We focused on the incidence, characteristics, risk factors, and mortality of AKI in advanced lung cancer patients receiving PD-1 inhibitors.
View Article and Find Full Text PDFBackground: Ovarian follicles, which are the basic units of female reproduction, are composed of oocytes and surrounding somatic (pre) granulosa cells (GCs). A recent study revealed that signaling in somatic preGCs controlled the activation (initial recruitment) of follicles in the adult ovaries, but it is also known that there are two waves of follicle with age-related heterogeneity in their developmental dynamics in mammals. Although this heterogeneity was proposed to be crucial for female reproduction, our understanding of how it arises and its significance is still elusive.

Calciphylaxis is a rare disease characterized histologically by microvessel calcification and microthrombosis, with high mortality and no proven therapy. Here, we reported a severe uremic calciphylaxis patient with progressive skin ischemia, large areas of painful malodorous ulcers, and mummified legs. Because of the worsening symptoms and signs refractory to conventional therapies, treatment with human amnion-derived mesenchymal stem cells (hAMSCs) was approved.

Here, we performed high-resolution, three-dimensional ovarian vascular imaging and traced the pattern of ovarian angiogenesis and vascular development in the long term. We found that angiogenesis was mainly active on ovarian follicles and corpus luteum and that robust angiogenesis constructs independent but temporary vascular networks for each follicle.

Methods: This retrospective study included 355 patients admitted from the nephrology department with modification of diet in renal disease estimated glomerular filtration rate (MDRD eGFR) < 60 ml/min/1.73 m.
Purpose: The combination of vancomycin and piperacillin/tazobactam (VAN + PTZ) provides a broad spectrum of activity against multiple pathogens. However, a major issue in previous research concerned significant nephrotoxicity associated with this drug combination, and most studies have been conducted in American and European countries, with no similar data available from China. Therefore, this study evaluated the nephrotoxic effects of VAN + PTZ in a large-scale Chinese cohort to determine the prevalence of acute kidney injury (AKI) in this population by comparing PTZ and vancomycin monotherapies and the combined use of vancomycin and β-lactam antibiotics.

The aim of this study was to clarify the association between CRRT and 28-day mortality in critically ill coronavirus disease 2019 (-COVID-19) patients receiving mechanical ventilation.
Materials And Methods: 112 respiratory decompensated critically ill adult patients with COVID-19 admitted to a COVID-19-designated ICU were included in this retrospective cohort study.
Background: Immune checkpoint inhibitors (ICIs) have brought a paradigm shift to cancer treatment. However, little is known about the risk of renal adverse events (RAEs) of ICI-based regimens, especially ICI combination therapy.
Methods: We carried out a network meta-analysis of randomized controlled trials (RCTs) to compare the risk of RAEs between ICI-based regimens and traditional cancer therapy, including chemotherapy and targeted therapy.
Objective: The objective of this study is to investigate the association between the serum sclerostin, the coronary artery calcification (CAC), and patient outcomes in maintenance dialysis patients.
Methods: We performed a prospective cohort study of 65 maintenance dialysis patients in 2014, including 39 patients on peritoneal dialysis and 26 on hemodialysis, and followed up for 5 years. Parameters of mineral metabolism including bone-specific alkaline phosphatase, fibroblast growth factor 23, sclerostin, and other biochemical factors were determined at the baseline.
Patients with pre-existing chronic diseases are more susceptible to coronavirus disease 2019 (COVID-19), yet the underlying causes of increased risk are of infection remain unclear. Angiotensin-converting- enzyme 2 (ACE2), the cell surface receptor that recognizes the coronavirus spike protein has protective effects against inflammation and chronic hyperglycemia in animal models. The roles of ACE2 in severe SARS-CoV-2 infections remains ambiguous due to contradictory findings.

Here we combine endogenous-fluorescent tracing mouse models with a high-resolution live-cell imaging system to characterize oocyte-derived mushroom-like microvilli (Oo-Mvi), which mediate germ-somatic communication in mice. We perform 3D live-cell imaging to show that Oo-Mvi exhibit cellular characteristics that fit an exocrine function for signaling communication.
