Simple light use efficiency (epsilon) models of net primary production (NPP) have recently been given great attention (NPP = epsilon x absorbed photosynthetically active radiation). The underlying relationships have, however, not been much studied on a time step less than a month. In this study daily NPP was estimated as the sum of net ecosystem exchange (NEE) and heterotrophic respiration (R-h) o

Objective. To search for primary hyperaldosteronism (PHA) among previously known hypertensive patients in primary care, using the aldosterone/renin ratio (ARR), and to evaluate clinical and biochemical characteristics in patients with high or normal ratio. Design. Patient survey study. Setting and subjects. The study population was recruited by written invitation among hypertensive patients in two

BACKGROUND: Metabolic syndrome (MS) is a common health problem in menopausal women. According to The Adult Treatment Panel (ATP) III, MS includes the combination of three or more of the following risk factors: abdominal obesity, glucose intolerance, high blood pressure, high serum triglycerides and low levels of high density lipoprotein cholesterol. OBJECTIVES: To assess the prevalence of the MS i

People aged 60 or more are the most frequent users of healthcare services. In this age range, however, both frequent and infrequent users can be found. Frequent users have high rates of illnesses. Previous research has found that the frequency may be influenced also by psychological and social factors. The aim of this study was to investigate to what degree such factors add to the explanation of d

OBJECTIVE: to investigate the factors that influence the experience of mothers and fathers when they have chosen to return home, earlier than is the normal routine, following the birth of their baby.

S

Ovarian cancer is the leading cause of death from gynecologic malignancies among women worldwide. Little is known about reproductive factors or lifestyle determinants and ovarian cancer prognosis. The objective of this study was to examine whether ovarian cancer survival is influenced by reproductive history, anthropometric characteristics, prediagnostic life-style factors and family history or br

The osteoblast-derived protein osteocalcin has recently been shown to affect adiposity and glucose homeostasis in mice, suggesting that the skeleton influences energy metabolism through an endocrine mechanism. The aim of this study was to investigate the relationship between plasma osteocalcin and parameters reflecting fat mass and glucose homeostasis in humans. Fasting levels of plasma osteocalci
