Purpose: The prognosis of hepatocellular carcinoma (HCC) with extrahepatic metastases (EM) is poor. The efficacy and safety of transcatheter arterial chemoembolization combined with lenvatinib plus anti-programmed cell death 1 inhibitors (triple therapy) for HCC with EM remains unclear. In this study, we aimed to determine the efficacy and safety of triple therapy in HCC patients with EM.

Introduction: Patients with hepatocellular carcinoma (HCC) and inferior vena cava tumor thrombus (IVCTT) have poor prognosis. Combination therapy involving the blockade of programmed cell death protein 1 (PD-1) and tyrosine kinase inhibitors is an efficient treatment strategy for advanced HCC. However, surgical treatment after a combination of systemic therapy and transarterial chemoembolization (TACE) for HCC with IVCTT has not been widely reported, and the efficacy and safety of this treatment have not been studied.

The coronavirus disease (COVID-19) pandemic has resulted in an increasing population that is experiencing a wide range of long-lasting symptoms after recovery from the acute infection. Long COVID refers to this specific condition and is associated with diverse symptoms, such as fatigue, myalgias, dyspnea, headache, cognitive impairment, neurodegenerative symptoms, anxiety, depression, and a sense of despair. The potential of hyperbaric oxygen therapy (HBOT) to improve chronic fatigue, cognitive impairments, and neurological disorders has been established; therefore, the use of HBOT to treat long COVID has also been studied.

Background: This study aimed to determine whether salvage hepatectomy offers prognostic advantages for unresectable hepatocellular carcinoma (uHCC) patients with clinical complete response (cCR) after conversion therapy.

Methods: A total of 74 consecutive uHCC patients with cCR after conversion therapy at seven major cancer centers in China between October 2018 and December 2021 were included. One-to-one propensity score matching (PSM) was performed to minimize the influence of potential confounders.

Background And Aims: Transcatheter arterial chemoembolization combined with lenvatinib and PD-1 inhibitors (triple therapy) exhibits promising efficacy for unresectable hepatocellular carcinoma (uHCC). We aimed to evaluate the prognosis of patients with uHCC who received triple therapy and develop a prognostic scoring model to identify patients who benefit the most from triple therapy.

Methods: A total of 246 patients with uHCC who received triple therapy at eight centers were included and assigned to the training and validation cohorts.

Purpose: In recent years, immune checkpoint inhibitors have been used in combination with tyrosine kinase inhibitors and local therapies, creating a new era in treating hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). However, the benefits of this triple therapy remain unclear. Thus, this study evaluated whether the combination of transarterial chemoembolization (TACE), lenvatinib, and programmed death-1 (PD-1) inhibitors (triple therapy) was effective and safe for unresectable HCC with main trunk portal vein tumor thrombus (Vp4).

Brain-derived neurotrophic factor (BDNF) is a major neurotrophin in the central nervous system that plays a critical role in the physiological brain functions via its two independent receptors: tropomyosin-related kinase B (TrkB) and p75, especially in the neurodevelopment. Disrupting of BDNF and its downstream signals has been found in many neuropsychological diseases, including attention-deficit hyperactivity disorder (ADHD), a common mental disorder which is prevalent in childhood. Understanding the physiological functions of BDNF during neural development and its potential relationship with ADHD will help us to elucidate the possible mechanisms of ADHD and to develop therapeutic approaches for this disease.

Heat stress decreases natural immunity making cows more vulnerable to diseases. A previous study reported that daidzein can enhance animal resistance to heat stress and regulate animal immunocompetence. However, it is unclear whether daidzein regulates the immune performance of late lactation cows under heat stress.

A common defect encountered in the spermatozoa of male infertility patients is an idiopathic failure of sperm-egg recognition. In order to resolve the molecular basis of this condition we have compared the proteomic profiles of spermatozoa exhibiting an impaired capacity for sperm-egg recognition with normal cells using label free mass spectrometry (MS)-based quantification. This analysis indicated that impaired sperm-zona binding was associated with reduced expression of the molecular chaperone, heat shock 70 kDa protein 2 (HSPA2), from the sperm proteome.

Objective: To determine association between defective protein kinases C (PKC) and A (PKA) and disordered zona pellucida (ZP)-induced acrosome reaction (DZPIAR) in normozoospermic infertile men with normal sperm-ZP binding.

Design: Sperm from DZPIAR infertile men were treated without (control) or with (test) phorbol myristate acetate (PMA, PKC activator) or dibutyryl cyclic AMP (dbcAMP, PKA activator) under in vitro standard culture condition. The ZP-induced AR was assessed and compared between control and test.

The aim of this study was to compare sperm velocity, hyperactivation, zona pellucida (ZP) binding and ZP-induced acrosome reaction (AR) between Quinn's advantage fertilization (QAF), human tubal fluid (HTF) and Ham's F10 media. Semen samples were obtained from normozoospermic men and motile spermatozoa were prepared by gradient centrifugation (PureSperm). Unfertilized oocytes from clinical IVF were used for spermatozoa-oocyte interaction tests.

This goal of this study was to compare the outcomes of conventional intracytoplasmic sperm injection (ICSI; control group, n = 53 couples) and a modified ICSI technique using zona pellucida (ZP)-bound sperm for injection of oocytes (test group, n = 53 couples). The proportion of high-quality embryos (grades 1 and 2) and implantation rate were significantly higher in the test group than in the control group, but the difference in fetal heart pregnancy rate was not significant despite seven more pregnancies being obtained in the test group (26 pregnancies) versus the control group (19 pregnancies) following fresh embryo transfers.

This study was to compare the outcomes of conventional (scientist-selected sperm) intracytoplasmic sperm injection (ICSI) and a modified ICSI using zona pellucida (ZP)-bound sperm. Although with 39 couples in each group there was no statistical significance in fertilization, embryo development, implantation, and fetal heart clinical pregnancy rates, the higher implantation and clinical pregnancy rates with ZP-bound sperm encourages further evaluation with larger numbers of subjects using sibling oocytes to determine if the ZP-bound sperm are biologically and functionally superior.

The anti-acrosin monoclonal antibody AcrC5F10 inhibited proacrosin activation, proacrosin-human zona pellucida glycoprotein A (ZPA) binding, and the zona pellucida (ZP)-induced acrosome reaction of the ZP-bound spermatozoa but had no significant effect on sperm-ZP binding. These results suggest that proacrosin-acrosin may play an important role in the ZP-induced acrosome reaction of spermatozoa after primary binding to the ZP.

The aim of this study was to determine the relationship between seminal zinc concentration and spermatozoa-zona pellucida (ZP) binding and the ZP-induced acrosome reaction (ZPIAR) in subfertile men. Semen analyses and seminal zinc concentration assessments were carried out according to the World Health Organization manual for 458 subfertile men. A spermatozoa-ZP interaction test was carried out by incubating 2 x 10(6) motile spermatozoa with a group of four unfertilized oocytes obtained from a clinical in vitro fertilization programme.
