Sulindac (K-80003) with nab-paclitaxel and gemcitabine overcomes drug-resistant pancreatic cancer.

The Nab-paclitaxel combined with gemcitabine (AG) regimen is the main chemotherapy regimen for pancreatic cancer, but drug resistance often occurs. Currently, the ability to promote sensitization in drug-resistant cases is an important clinical issue, and the strategy of repurposing conventional drugs is a promising strategy. This study aimed to identify a classic drug that targets chemotherapy resistance's core signaling pathways and combine it with the AG regimen to enhance chemosensitivity.

Changing trends in penile prosthesis implantation in China and an overview of postoperative outcomes from a single center.

Background: Surgical penile prosthesis implantation (PPI) procedures have only recently been introduced to mainland China, with the overall number of such procedures having been conducted to date remaining relatively low. Accordingly, relatively little remains known with respect to the annual trends in PPI. Accordingly, this study was developed with the goal of clarifying these trends across different hospitals in mainland China, while also providing a single-center overview of post-PPI patient outcomes.

The Efficacy and Safety of Thrice vs Twice per Week Low-Intensity Pulsed Ultrasound Therapy for Erectile Dysfunction: A Randomized Clinical Trial.

Background: A recent sham-controlled clinical study has shown that low-intensity pulsed ultrasound twice per week can safely and effectively treat patients with mild-to-moderate erectile dysfunction (ED). However, large-scale clinical trials are needed to verify its efficacy and safety and determine a reasonable treatment interval.

Aim: To study whether low-intensity pulsed ultrasound therapy thrice per week is non-inferior to twice per week in patients with mild-to-moderate ED.

Low-Intensity Pulsed Ultrasound Enhanced Adipose-Derived Stem Cell-Mediated Angiogenesis in the Treatment of Diabetic Erectile Dysfunction through the Piezo-ERK-VEGF Axis.

Objectives: Erectile dysfunction is a major comorbidity of diabetes. Stem cell transplantation is a promising method to treat diabetic erectile dysfunction. In this study, we evaluated whether low-intensity pulsed ultrasound (LIPUS) could enhance the efficacy of adipose-derived stem cells (ADSCs) and investigated the underlying molecular mechanism.

Single-cell transcriptome atlas of the human corpus cavernosum.

The corpus cavernosum is the most important structure for penile erection, and its dysfunction causes many physiological and psychological problems. However, its cellular heterogeneity and signalling networks at the molecular level are poorly understood because of limited access to samples. Here, we profile 64,993 human cavernosal single-cell transcriptomes from three males with normal erection and five organic erectile dysfunction patients.

Electrochemiluminescence Biosensor for Hyaluronidase Based on the Adjustable Electrostatic Interaction between the Surface-Charge-Controllable Nanoparticles and Negatively Charged Electrode.

A novel electrochemiluminescence (ECL) biosensor for hyaluronidase (HAase) based on the adjustable electrostatic interaction between the surface-charge-controllable nanoparticles and negatively charged electrode has been devised. Hyaluronic acid (HA)-coated amino-modified ruthenium bipyridine-doped silica nanoparticles (Ru@SiO-NH@HA NPs) have been synthesized and act as ECL indicators, and the surface of this particle is negatively charged because HA contains a large amount of OH- and COO-. The strong electrostatic repulsion between the Ru@SiO-NH@HA NPs and negatively charged indium tin oxide (ITO) electrode surface leads to the detection of a low-intensity ECL signal.

Novel bi-allelic variants in KASH5 are associated with meiotic arrest and non-obstructive azoospermia.

KASH5 is an essential component of the LINC (linker of the nucleoskeleton and cytoskeleton) complex that regulates chromosome movements and nuclear envelope (NE) remodeling in mouse spermatocytes during meiosis prophase I, but its expression and function in human cells, as well as its association with male infertility are largely unknown. In this study, a novel heterozygous copy number variation (CNV) (seq [GRCh37] del(19) (19q13.33) chr19: g.

Novel Bi-Allelic Variants of Cause Sertoli Cell-Only Syndrome and Non-Obstructive Azoospermia.

Non-obstructive azoospermia (NOA) is the most severe disease in male infertility, but the genetic causes for the majority of NOA remain unknown. FANCM is a member of Fanconi Anemia (FA) core complex, whose defects are associated with cell hypersensitivity to DNA interstrand crosslink (ICL)-inducing agents. It was reported that variants in (MIM: 609644) might cause azoospermia or oligospermia.

RNA-binding protein ELAVL2 plays post-transcriptional roles in the regulation of spermatogonia proliferation and apoptosis.

Objectives: RNA-binding proteins (RBPs) play essential post-transcriptional roles in regulating spermatogonial stem cells (SSCs) maintenance and differentiation. We identified a conserved and SSCs-enriched RBP ELAVL2 from our single-cell sequencing data, but its function and mechanism in SSCs were unclear.

Materials And Methods: Expressions of ELAVL2 during human and mouse testis development were validated.

Vasal vessel-sparing microsurgical single-armed vasoepididymostomy to epididymal obstructive azoospermia: A retrospective control study.

This study aimed to evaluate the efficacy and safety of vasal vessel-sparing modified single-armed 2-suture longitudinal intussusception vasoepididymostomy (SA-LIVE) to epididymal obstructive azoospermia patients. Forty consecutive epididymal obstructive azoospermia cases, who underwent microsurgical vasoepididymostomy in Shanghai General Hospital from January 2019 to October 2019, were included in this study. Twenty cases underwent SA-LIVE (group A), and 20 cases underwent vasal vessel-sparing SA-LIVE (group B).

Transverse testicular ectopia associated with persistent Mullerian duct syndrome in infertile male: two case reports and literature review.

Transverse testicular ectopia (TTE) associated with persistent Mullerian duct syndrome (PMDS) is a rare form of male pseudohermaphroditism usually unexpectedly found at surgery for cryptorchidism or inguinal hernia in children. Its etiology and prevalence are unclear, although defects in the gene that encodes anti-Mullerian hormone (AMH) or AMH receptor has been generally considered as the major cause. Adult cases of TTE associated with PMDS are even more peculiar, as the adult patients usually present more complex medical history, require more comprehensive medical examination and management.

Single-cell analysis of developing and azoospermia human testicles reveals central role of Sertoli cells.

Clinical efficacy of treatments against non-obstructive azoospermia (NOA), which affects 1% of men, are currently limited by the incomplete understanding of NOA pathogenesis and normal spermatogenic microenvironment. Here, we profile >80,000 human testicular single-cell transcriptomes from 10 healthy donors spanning the range from infant to adult and 7 NOA patients. We show that Sertoli cells, which form the scaffold in the testicular microenvironment, are severely damaged in NOA patients and identify the roadmap of Sertoli cell maturation.
