Do contextual factors have a role in periodontal disease?

Do pre-performance routines have a role in free throws accuracy of basketball players?

A significant portion of research exploring pre-performance routines in sport has focused on the behavioral and temporal characteristics of the routines. This study aimed to investigate the role of behavioral and temporal consistency in those pre-performance routines. The duration and dominant behavioral patterns exhibited before each free throw (N = 1025) were observed during a total of 60 Ira...

Do mitochondrial DNA mutations have a role in neurodegenerative disease?

A decline in mitochondrial function has long been shown to exist in neurodegenerative disease. Whether this decline is a secondary consequence of other factors or whether it causes the eventual death of a cell is unknown. In this review, we will discuss some of the major evidence surrounding mitochondrial DNA mutations leading to mitochondrial dysfunction in neurodegenerative disease and discus...

Do putative endogenous digitalis-like factors have a physiological role?

Do leukocytes have a role in hypertension?

In this issue of Hypertension, Schmid-Schonbein and colleagues investigate the possible role of leukocytes in the pathophysiology of hypertension. The authors measured leukocyte counts and spontaneous leukocyte activation of freshly drawn blood in spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto (WKY) rats. Special care was taken to control various factors (source of rats, ag...

Relationship of blood groups to pemphigus: Do blood group antigens have a biological role? A Case-control study

Background: ABO blood group antigens may play a role in the pathophysiology of certain diseases. Several studies have investigated the relation between blood group and autoimmune disorders. In this research, we evaluated the associations between ABO blood types and rhesus (Rh) factor in pemphigus patients.Methods: In this case-control, hospital-based study, we evaluated the prevalence of blood ...
