To assess the immune potential of spiders, in the present study juvenile and adult females of were exposed to infection, injury by a nylon monofilament and a combination of both. The expression level of selected immune-related genes: defensin 1 (Pt), lysozyme 1 (Pt), lysozyme C (Pt), lysozyme M1 (Pt), autophagy-related protein 101 (Pt), dynamin (Pt) and heat shock proteins (HSP70) (Pt, Pt, Pt), production of lysozyme and HSP70 proteins, and hemocytes viability were measured. The obtained results indicated expression of the lysozyme, autophagy-related protein and HSP70 genes in both ontogenetic stages of . It has been also shown that the simultaneous action of mechanical and biological factors causes higher level of lysozyme and HSP70, cell apoptosis intensity and lower level of hemocytes viability than in the case of exposure to a single immunostimulant. Moreover, mature females showed stronger early immune responses compared to juveniles.

N-acetylated sugars in clownfish and damselfish skin mucus as messengers involved in chemical recognition by anemone host.
Sci Rep

Department of Computational Biology, Faculty of Biology and Medicine, University of Lausanne, Lausanne, Switzerland.
The clownfish - sea anemone system is a great example of symbiotic mutualism where host «toxicity» does not impact its symbiont partner, although the underlying protection mechanism remains unclear. The regulation of nematocyst discharge in cnidarians involves N-acetylated sugars like sialic acid, that bind chemoreceptors on the tentacles of sea anemones, leading to the release of stings. It has been suggested that clownfish could be deprived of sialic acid on their skin surface, sparing them from being stung and facilitating mutualism with sea anemones.

Various reference intervals are available for interpreting biochemical results in alpacas, but physiological variations due to age, sex or season should also be considered. Particularly, information on the influence of age is scarce.

Rationale: The MYOC gene is associated with juvenile open-angle glaucoma (JOAG). This study aims to provide genetic counseling for a Chinese JOAG family by detecting MYOC mutations to identify high-risk individuals for early JOAG intervention. It also supplements the clinical characteristics of glaucoma patients with MYOC gene mutations.

Owing to its topographic variations, Ethiopia is a biodiversity-rich country. However, the long-term degradation of resources has resulted in isolated forest patches largely around sacred places. Thus, this work was aimed to evaluate the plant community formation and structural dynamics of the Abraham Sacred Forest patch.

Juvenile dermatomyositis with emphasized vasculopathy is rare, but the most severe form of the disease, with a poor prognosis with relapsing and chronic course or, in some cases, lethal outcome. We present a case of a 19-year-old Caucasian female, who developed severe acute juvenile dermatomyositis with emphasized multisystem vasculopathy, including retinal vasculopathy and maculopathy (cotton-wool spots, retinal hemorrhages, macular edema) at the age of 8. Due to no response to standard treatment protocols and rapid worsening of clinical symptoms and laboratory findings, a TNF inhibitor (infliximab) was introduced after the third week of treatment resulting in complete normalisation of muscle enzyme levels and complete resolution of eye changes within the next 2 weeks with a gradual general recovery.
