Background: The use of C-type natriuretic peptide (CNP) combined with cysteamine during pre-in vitro maturation (IVM) can help establish an effective pre-IVM system. Aims: This study was designed to investigate the effects of CNP combined with cysteamine on meiotic maturation and developmental competence of bovine oocytes in vitro. Met...

To evaluate the effect of melatonin supplementation in maturation medium for human 'rescue IVM' and investigate differences in transcriptomic profile of blastocysts developed from oocytes matured in vitro with/without melatonin treatment and in vivo, a total of 314 GV oocytes and 320 MI oocytes were collected from 200 patients younger than 35 years old undergoing ICSI cycle. The oocytes were ra...

BACKGROUND Several oral ivermectin (IVM) formulations for use in sheep are available in the pharmaceutical veterinary market in different countries. All of them are indicated at the same dose rate to treat the gastrointestinal nematodes. However, there is a lack of information on the relative systemic exposure (plasma bioavailability) and clinical efficacy among oral formulations routinely used...

Ivermectin is a well-known and widely used anti-parasitic drug. Recently, in vitro data suggest anti-viral efficacy of the drug, albeit at much higher concentrations than currently approved. Despite warnings by several governing bodies, (uncontrolled) human use ivermectin has significantly increased during COVID-19 epidemic. This study thus aimed to elucidate potential neurological risk particu...

Onchocerciasis (river blindness) is a human disease caused by the filarial worm Onchocerca volvulus. Adult worms can live for over a decade in skin nodules of affected humans, releasing millions of microfilariae that cause debilitating itching and blindness [1]. An estimated 37 million people are infected [2], and there are 46,000 new cases of blindness annually (http://www.apoc.bf/). Internati...

Oocyte in vitro maturation (IVM) has become a valuable technological tool for animal breeding and cloning and the treatment of human infertility because it does not require the administration of exogenous gonadotropin to obtain fertilizable oocytes. However, embryo development after IVM is lower compared to in vivo maturation, most likely because oocytes collected for IVM are heterogeneous with...

OBJECTIVE To determine a successful method of selecting patients for natural cycle IVF combined with in vitro maturation (IVM) of immature oocytes and to determine treatment efficacy. DESIGN Retrospective analysis of IVF treatments. SETTING Hospital IVF clinic. PATIENT(S) Women with infertility according to ovarian reserve and endocrine profile were selected for different treatments. IN...

ATP-binding cassette (ABC) transporters comprise a large paralogous protein family and several confer drug resistance. Ivermectin (IVM) is the only drug approved for treatment of onchocerciasis and is a substrate for some ABC transporters. Furthermore, there is accumulating evidence that IVM selects on some ABC transporter genes in Onchocerca volvulus and other parasitic nematodes. The onchocer...

The support vector machine (SVM) is known for its good performance in binary classification, but its extension to multi-class classification is still an on-going research issue. In this paper, we propose a new approach for classification, called the import vector machine (IVM), which is built on kernel logistic regression (KLR). We show that the IVM not only performs as well as the SVM in binar...

BACKGROUND During cytoplasmic oocyte maturation, Ca(2+) currents are vital for regulating a broad range of physiological processes. Recent studies have demonstrated that DMSO and EG cause large transient increases in intracellular Ca(2+) in mouse oocytes. The CP used in vitrifying protocols also increases the intracellular calcium transient. The aim of this study is to evaluate the effects of v...
