BACKGROUND Scabies is one of the commonest dermatological conditions globally; however it is a largely underexplored and truly neglected infectious disease. Foremost, improvement in the management of this public health burden is imperative. Current treatments with topical agents and/or oral ivermectin (IVM) are insufficient and drug resistance is emerging. Moxidectin (MOX), with more advantageo...

Background. Ivermectin (IVM) reduces the lifespan of malaria-transmitting mosquitoes after feeding on humans treated with IVM. If this effect is sufficiently long and strong, IVM could form part of a drug combination that not only treats malaria patients but also reduces onward transmission. Limited data are available on the exact duration of the mosquitocidal effect of IVM; daily mosquito feed...

Physical removal of mammalian cumulus-oocyte complexes (COCs) from ovarian follicles results in spontaneous resumption of meiosis, largely because of a decrease in cAMP concentrations, causing asynchrony between cytoplasmic and nuclear maturation and decreased oocyte developmental competence. The aim of this study was to modulate cAMP concentrations within ovine COCs to delay spontaneous nuclea...

Ion channels are targets for many drugs including insecticides and anthelminthic agents such as ivermectin (IVM) and moxidectin (MOX). IVM has been shown to activate glutamate-gated chloride channels (GluCls) from the free-living nematode, Caenorhabditis elegans. Haemonchus contortus is a parasitic nematode that is also extremely sensitive to IVM. The high sensitivity of H. contortus to IVM is ...

Vitrification of matured oocytes is widely adopted in human clinics and animal research laboratories. Cryopreservation of immature oocytes, particularly those at metaphase I (MI), remains a challenge. In the present work, mouse MI oocytes denuded of cumulus cells were vitrified and warmed (V/W) either prior to (V/W-BEFORE-IVM, n = 562) or after (V/W-AFTER-IVM, n = 664) in vitro maturation (IVM)...

OBJECTIVE The aim of this study was to report a case series of in vitro matured (IVM) oocyte freezing in gynecologic cancer patients undergoing radical surgery under time constraints as an option for fertility preservation (FP). METHODS Case series report. University-based in vitro fertilization center. Six gynecologic cancer patients who were scheduled to undergo radical surgery the next day...

PURPOSE The intravitreal membrane (IVM) is a membranous structure between the primary and secondary vitreous bodies in developing mammalian eyes. In this study, for the first time the histogenesis of the IVM and the relationship between the hyaloid vasculature and the IVM was characterized in newborn mice. METHODS Eyes of mice less than 12 days old were fixed and embedded. From these, serial ...

BACKGROUND The World Health Organization (WHO) recommends integrated vector management (IVM) as a strategy to improve and sustain malaria vector control. However, this approach has not been widely adopted. OBJECTIVES We comprehensively assessed experiences and findings on IVM in Kenya with a view to sharing lessons that might promote its wider application. METHODS The assessment used inform...

BACKGROUND In vitro maturation (IVM) of mammalian oocytes has potential health benefits for patients undergoing assisted reproduction as an alternative to gonadotrophin treatment. This procedure is also useful for studying the process of oocyte and early embryo development. However, oocytes undergoing IVM have much lower competence than in vivo matured oocytes. Efforts to optimize IVM success h...

Ivermectin (IVM), a widely used antiparasitic agent in human and veterinary medicine, was recently shown to augment macroscopic currents through rat P2X(4) receptor channels. In the present study, the effects of IVM on the human P2X(4) (hP2X(4)) receptor channel stably transfected in HEK293 cells were investigated by recording membrane currents using the patch clamp technique. In whole-cell rec...
