Body mass index and adipokines/cytokines dysregulation in systemic sclerosis.

Body fat has regulatory functions through producing cytokines and adipokines whose role in the pathogenesis of systemic sclerosis (SSc) is currently emerging. Changes in body mass, either over- or underweight, entail a dysregulation of the cytokine/adipokine network that may impact upon SSc disease activity. We evaluated serum levels of adipokines and cytokines in SSc patients and correlated them to clinical features and body mass index (BMI) categories.

Serum sCD40L levels are increased in patients with psoriatic arthritis and are associated with clinical response to apremilast.

The pathogenesis of psoriatic arthritis (PsA) involves several pathways, including the CD40/CD40L signaling which promotes the release of multiple cytokines. Transmembrane CD40L is also released in soluble form (sCD40L) and phosphodiesterase 4 (PDE4) seems to be involved in its cleavage. We aimed to investigate whether apremilast, a PDE4 inhibitor, could modify circulating levels of sCD40L in PsA patients, and the possible associations of these changes with clinical response.

Chondrocytes treated with different shock wave devices.

Background: Shock wave treatment is used for several orthopedic diseases and there are different devices available. Until now, there have been no experimental studies on the effects of these different generators.

Methods: We carried out an experimental study to compare the effects of three focused generators (electro-magnetic, piezoelectric and electro-hydraulic) as well as a radial generator on healthy and osteoarthritis chondrocytes.

Giardia and Cryptosporidium in water: evaluation of two concentration methods and occurrence in wastewater.

Giardia and Cryptosporidium are important agents of water-borne parasitic diseases. In this work we have examined the recovery efficiency of two methods for concentrating Giardia cysts and Cryptosporidium oocysts from water: a membrane filtration method and a crossflow filtration method. Results demonstrated a higher recovery efficiency for crossflow filtration method in comparison to the membrane filtration method.
