Polymorphonuclear leukocyte membrane fluidity and cytosolic Ca2+ content at baseline and after activation in essential hypertension

Polymorphonuclear leukocyte membrane fluidity and cytosolic Ca2+ content in young adults with acute myocardial infarction. Evaluation at the initial stage and after 12 months

Our aim was to examine two aspects of polymorphonuclear leukocyte (PMN) rheology (membrane fluidity and cytosolic Ca2+ content), at baseline and after in vitro activation, in a group of young adults with acute myocardial infarction (AMI) at the initial stage and after 12 months. We enrolled 21 AMI subjects aged < or = 45 years (mean age 41.1 +/- 3.5 years) and evaluated PMN membrane fluidity, labelling intact PMN cells with the fluorescent probe 1,4-(trimethylamino)-phenyl-4-phenylhexatriene and the PMN cytosolic Ca2+ content marking PMN cells with the fluorescent probe Fura 2-AM, at baseline and after in vitro activation with 4-phorbol 12-myristate 13-acetate (PMA) and N-formyl-methionyl-l…

Executive functioning in autism spectrum disorders: a case-control study in preschool children.

Background: Autism spectrum disorders (ASD) are neurobehavioral and developmental conditions that include impairments in a triad of behavioral domains: social development, communication and repetitive behavior/obsessive interests. This case-control study aims to assess executive functioning in ASD preschoolers. Methods: A sample of 50 children participated in the study (24 males and 26 females; age ranged between 2.7 and 3.5 years). The study sample was subdivided into two groups: 25 ASD children and 25 typically developing children as a control group. All participants were administered the BRIEF-P test to assess executive functioning. Results: The two groups were counterbalanced for age an…

Granulocyte cytosolic calcium in type 2 diabetes

Lipid peroxidation and total antioxidant status in juvenile myocardial infarction.

In a group of young subjects with acute myocardial infarction (AMI) (97 men and 8 women; mean age 39.6+/-5.5 years) we examined the thiobarbituric acid - reactive substances and the total antioxidant status at the initial stage and after 12 months. The same parameters were examined in a group of 55 control subjects. Our results show that, while in control subjects there was a negative correlation (p<0.001) between these two parameters, no correlation was found in juvenile myocardial infarction at the initial stage as well as after 12 months.
