Some biological aspects of semen were investigated in the Persian sturgeon, Acipenser persicus, by determination of seminal plasma indices (ionic composition and osmolality), sperm density and their relationships with sperm motility. The osmolality of seminal plasma ranged from 42.00 to 111.00 mOsmol Kg-1. The concentrations of Sodium (Na+), Potassium (K+), Chloride (Cl-), Calcium (Ca2+) and Ma...

Introduction: The aim of this research was to study the effect of a 6-week supplemented diet on increasing bone density by measuring calcium, phosphorus and bone mineral density (BMD) in male rats. Materials and methods: In this experimental study, 24 Wistar male rats, aged between 15 and 20 days, were selected. The rats were randomly divided into 3 groups: immune system supplement (ISS), ...

Calcium releases of non-excitable cells are generally a combination of oscillatory and non-oscillatory patterns, and factors affecting the calcium dynamics are still to be determined. Here we report the influence of cell density on calcium increase patterns of clonal cell lines. The majority of HeLa cells seeded at 1.5 x 104/cm2 showed calcium oscillations in response to histamine and ATP, wher...

introduction: an ideal intracanal medicament should be able to eliminate any remaining intracanal microorganism. the aim of this study was to compare the antimicrobial effects of bioglass 45s5 with calcium hydroxide on enterococcus ( e ) faecalis in-vitro . materials & methods: direct exposure test (det) was used to evaluate the antimicrobial effect of bioglass 45s5, calcium hydroxide and norma...

BACKGROUND A better understanding of factors that affect breast density, one of the strongest breast cancer risk indicators, may provide important clues about breast cancer etiology and prevention. This study evaluates the association of vitamin D and calcium, from food and/or supplements, to breast density in premenopausal and postmenopausal women separately. METHODS A total of 777 premenopa...

CONTEXT Calcium Nephrolithiasis is a multifactorial disease; in its pathophysiology is involved various minerals and metabolic factors that may be altered, including bone and phosphor-calcium metabolism. OBJECTIVE To establish the scientific evidence and demonstrate the relationship between calcium nephrolithiasis and bone mineral density loss, through the use of bone turnover markers, serum ...

  Background: The main purpose of this study was to determine the relationship between serum vitamin D and the status of bone mineral density in patients with low-energy hip and distal radius fracture. Methods: This retrospective case-control study was performed between January 2013 and January 2014. Participants aged 55 years or older were divided to case group including 85 patients with lo...
