The association between neural crest‐derived glia and melanocyte lineages throughout development and disease

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common

Antioxidants activities and lipid profile in the haemolymph of black and white-skinned giant African land snail (Archachatina marginata)

Folia Veterinaria
Antioxidants are compounds that eliminate oxidative stress in biological systems. The activities of antioxidants in black and white-skinned snails have not been compared in literature.

EFFECT OF CHANGES IN RELATIVE HUMIDITY AND AMBIENT TEMPERATURE ON REPRODUCTIVE PERFORMANCE AND EGG HATCHABILITY OF AFRICAN GIANT LAND SNAILS (ARCHACHATINA MARGINATA) REARED UNDER INTENSIVE MANAGEMENT DURING DRY SEASON [PDF]

Acta Scientifica Malaysia
The objective of this study was to evaluate the effect of relative humidity and temperature on egg production and hatchability. Forty-eight growing African Giant Land Snails (Archachatina marginata) between average weight of 400 to 600 grams were used ...

Stunting of the penis in Heleobia parchappii (Mollusca: Cochliopidae) and its relationship with parasitism [PDF]

, 2017
Penis anatomy is used to discriminate species of gastropods belonging to the family Cochliopidae; however, this characteristic may be affected by the presence of parasites.

Role of SoxE transcription factors in development and disease

Developmental Dynamics, EarlyView.
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Effects of water temperature on summer periphyton biomass in shallow lakes: a pan-European mesocosm experiment [PDF]

, 2015
Periphyton communities play an important role in shallow lakes and are controlled by direct forces such as temperature, light, nutrients, and invertebrate grazing, but also indirectly by planktivorous fish predation.

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

Ecography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

Modelling environmentally-mediated infectious diseases of humans: transmission dynamics of schistosomiasis in China. [PDF]

, 2010
Macroparasites of humans are sensitive to a variety of environmental variables, including temperature, rainfall and hydrology, yet current comprehension of these relationships is limited.
