Inhibition of photosynthesis by heavy metals is well documented. In this review the results are compared between in vitro experiments on isolated systems (chloroplasts, enzymes ­.), experiments on excised leaves and intact plants and algae in vivo. In vitro experiments suggest potential sites of heavy metal interaction with photosynthesis at several levels(More)
Accumulating evidence suggests that maternal obesity may increase the risk of metabolic disease in the offspring. We investigated the effects of established maternal diet-induced obesity on male and female offspring appetite, glucose homeostasis and body composition in rats. Female Wistar rats were fed either a standard chow (3% fat, 7% sugar [wt/wt]) or a(More)
Our previous work has suggested the presence of an insulin resistance in the adult offspring of streptozotocindiabetic pregnant rats. In this study we used the euglycaemic hyperinsulinaemic clamp technique with an isotope-dilution method to define and quantify this postulated insulin resistance in adult offspring of streptozotocin-diabetic rats. Under basal(More)
Severe diabetes in pregnant rats produces persistent metabolic consequences in adult offspring. This study investigated whether diabetes in pregnant rats could also lead to cardiovascular abnormalities in the adult offspring. Blood pressure, heart rate and in vitro vascular reactivity of small arteries were evaluated in female adult offspring of control(More)
The islets of Langerhans of the neonatal pancreas are composed of B cells and non-B cells. The non-B cells are a heterogeneous group and the composition appears to vary according to the staining method used. Silver impregnation methods sometimes impregnate a small number of B cells. No complete identity exists between argyrophilic cells (Hellerström-Hellman(More)
Vitamin D (D) deficiency during human pregnancy appears to disturb fetal growth and mineralization, but fetal development is normal in D-deficient rats and vitamin D receptor gene-ablated mice. We used the guinea pig model to investigate maternal and fetal effects of D deficiency. Pregnant (Pr) and nonpregnant (NPr) animals were fed a D-replete (+D) or(More)
The distribution of different celltypes (A, B, D and PP cells) of the endocrine pancreas was studied in both the normal and in the experimental diabetic non-pregnant and pregnant rat. In the normal rat the head (juxta duodenal part) of the pancreas contained more PP cells than the tail (12.5±1.1 versus 5.2±2.2) but fewer glucagon cells (19.0 ±3.5 versus(More)
A case of congenital arteriovenous malformation of the uterus in a 25-year-old woman with a long-standing history of recurrent menometrorrhagia is reported. Radiological diagnosis was based on hysterographic, computed tomographic, and angiographic findings. Treatment was performed with percutaneous transcatheter embolization.
