Protective Effects of Bee Venom (Apis mellifera) Against Cadmium‐Induced Hepatorenal Toxicity, Oxidative Stress, and Anxiety‐Like Behavior in Rats

Environmental Toxicology, EarlyView.
ABSTRACT Cadmium (Cd) is a persistent environmental heavy metal and a major public health concern because it persists in the body for long periods and gradually accumulates in vital organs, particularly the liver, kidneys, and brain. Chronic Cd exposure promotes the excessive production of reactive oxygen species (ROS), which ultimately leads to ...

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

Integrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Safety of Venom Immunotherapy in Pregnancy: A Multicentre Study

Allergy, EarlyView.
Venom immunotherapy (VIT) during pregnancy, when maintenance dose is well tolerated, can be continued. No increased risk of adverse effects to VIT or safety concerns for the pregnancy or the newborns were observed. No decreased efficacy of VIT, in case of re‐stings, was reported.

Distinct Gene Expression Profiles of Ara h 2‐Specific B Cells in Desensitization and Tolerance During Peanut Oral Immunotherapy

Allergy, EarlyView.
Gene expression of Ara h 2‐specific B cells over the course of the peanut OIT. Isotype of allergen‐specific B cells changes through OIT towards IgG4. Peanut OIT changes the gene expression of allergen‐specific memory B cells. OIT patients showed increased gene expression for regulatory B cells and immune regulation.
