Induction of ectosome formation by binding of phospholipases D from Loxosceles venoms to endothelial cell surface: Mechanism of interaction.

Members of the phospholipase D (PLD) superfamily found in Loxosceles spider venoms are potent toxins with inflammatory and necrotizing activities. They degrade phospholipids in cell membranes, generating bioactive molecules that activate skin cells. These skin cells, in turn, activate leukocytes involved in dermonecrosis, characterized by aseptic coagulative necrosis.

Novel insights into the application of recombinant mutated phospholipases D as antigens for developing new strategies against Loxoscelism.

Loxoscelism is the pathological condition triggered by a brown spider bite. The venom of these spiders is rich in phospholipases D (PLDs), which can induce virtually all local and systemic manifestations. Recombinant mutated PLDs from clinically relevant Loxosceles species in South America have been investigated as potential antigens to develop novel therapeutic strategies for loxoscelism.

Body weight variation is not an independent factor in the determination of functional hypothalamic amenorrhea in anorexia nervosa.

Objective: Functional hypothalamic amenorrhea (FHA) is one of the foremost manifestations in anorexia nervosa (AN), but a subset of patients have menses despite marked weight loss and underweight. The aim of our study was to investigate parameters potentially influencing FHA in AN.

Design And Methods: In this observational retrospective study, we selected 114 female patients with AN who completed a 12 months semi-residential rehabilitation program and a subsequent 12 months outpatient follow-up.

Mental health meets computational neuroscience: A predictive Bayesian account of the relationship between interoception and multisensory bodily illusions in anorexia nervosa.

Mental health disorders pose a significant challenge to society. The Bayesian perspective on the mind offers unique insights and tools that may help address a variety of mental health conditions. Psychopathological dysfunctions are often connected to altered predictive and active inference processes, in which cognitive and physiological pathogenic beliefs shape the clinical condition and its symptoms.

Production and Functional Evaluation of Anti- Sera Raised by Immunizations of Rabbits with Mutated Recombinant Phospholipases-D.

Loxoscelism is the clinical condition triggered after the bite of spiders of the genus . The main species involved in accidents in South America are , and . The only specific treatment is the anti- serum produced with crude venoms.
