The neotropical genus of stick insects, Phantasca Redtenbacher, 1906, was recently revised by Hennemann et al. (2018). However, the females and eggs of several species remain unknown, including all five species recorded from Brazil. The female and egg of Phantasca phantasma (Westwood, 1859) are here described for the first time, based on material available at the Museu de Zoologia da Universidade de São Paulo, Brazil (MZSP). A set of measurements of males is also given, in addition to the measurements of the holotype presented in Hennemann et al. (2018). This complement to the description of P. phantasma is particularly important because it is the type species of the genus (designated by Zompro, 2001), therefore providing additional grounds for future taxonomic decisions involving Phantasca.

Background: Nippostrongylus brasiliensis-a nematode of rodents-is commonly used as a model to study the immunobiology of parasitic nematodes. It is a member of the Strongylida-a large order of socioeconomically important parasitic nematodes of animals. Lipids are known to play essential roles in nematode biology, influencing cellular membranes, energy storage and/or signalling.

Oocyte maturation arrest (OMA) may occur at different stages, including the germinal vesicle (GV), metaphase I (MI), and metaphase II (MII). A total maturation arrest of human oocytes is rarely observed during fertilization (IVF). We have identified a case of infertile female for whom all oocytes fail to mature and are arrested at MI.

Background: Over the past five years, the pregnancy rate in assisted reproductive technology (ART) programs in Russia has remained relatively stable. The aim of this study was to assess the distribution of monocyte and macrophage subsets in the blood and follicular fluid of infertile women undergoing assisted reproductive technology.
Methods: The study involved 45 women with a mean age of 35 ± 4.

The most common and damaging plant parasitic nematodes are root-knot nematodes (RNK). Although hemp has been clearly infected by RNK, little information is available regarding the extent of the damage and losses caused. In addition, no information is available concerning hemp seed extracts' activity against RNK.

As a widely consumed, nutritious, and affordable food, eggs and their derivatives' impacts on obesity remain inconclusive. In this study, we aimed to determine the association between egg and egg-derived cholesterol consumption, and their change trajectories, with obesity among Chinese adults. : Longitudinal data collected by the China Health and Nutrition Survey from 1997 to 2015 were analyzed.
