A growing body of studies highlights involvement of neutrophils in cancer development and progression. Our aim was to assess the phenotypic and functional properties of circulating neutrophils from patients with chronic lymphocytic leukemia (CLL). The percentage of CD54+ and CD64+ neutrophils as well as CD54 expression on these cells were higher in CLL patients than in age-matched healthy controls. Neutrophils from CLL produced more reactive oxygen species (ROS) compared to controls in both resting and activated conditions...

La vit. D, o calcitriolo, è stata identificata inizialmente nei primi anni '20 ed ha un ruolo chiave nella regolazione del metabolismo osseo, nell'omeostasi del calcio e del fosforo e nel promuovere la mineralizzazione ossea. Le azioni della vit. D sono mediante tramite un recettore nucleare (VDR), che è espresso in numerosi organi come l'intestino, l'osso e il rene, ma anche nelle gonadi, nel seno, nel pancreas, nel sistema cardiovascolare, nel cervello (microglia) e nelle cellule del sistema immunitario...

Sunlight is regarded among greatest gifts that are presented in abundance to the human beings from the God. Sunlight is also a rich source of Vitamin D (Vit D) that prevents us from numerous ailments such as autoimmune disorders, various types of cancer, and the above all cardiovascular diseases (CVD). Evident from recent research that Vit D deficiency may be the cause for hypertension, cardiac autonomic imbalance, vascular endothelial dysfunction, metabolic syndrome, and even diabetes. Concurrently, many studies present research outcomes that are contradictory to earlier results and also raised a concern not for general public but also among their treating physicians...

A 49-year-old male patient presented due to recurrent pain and swelling in the left leg. The patient had had deep venous thrombosis with pulmonary embolism 5 years previously. Since then, he had been treated with Vit-k-antagonists. Pronounced paraumbilical collateral circulation of unknown origin was striking. Doppler sonographic evaluation pointed to May-Thurner syndrome. This was confirmed by phlebography. Venous stenting of the stenosis in the left iliac vein achieved long-term symptom improvement. This case report is intended to draw attention to the rare May-Thurner syndrome as an important differential diagnosis of deep vein thrombosis and, at the same time, identify diagnostic and therapeutic treatment strategies...

Heat-shock protein 70 (HSP70) plays a crucial role as intracellular cytoprotectant and molecular chaperone. A phenomenon of heat stress (HS) leads to production of these proteins that could be beneficial to cells during cryopreservation, which is also a stressful process for the cell. This study aimed to evaluate the protective effect of exposure of bovine oocytes to moderate HS during in vitro maturation (IVM) prior vitrification. First, oocytes were subjected to HS (41.5°C for 1 hr) at 0, 4, 8, 12 or 16 of IVM...
