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), iss p...

Phosphorus intake in Europe is far above recommendations. We present baseline data from three human intervention studies between 2006 and 2014 regarding intake and excretion of phosphorus and calcium. All subjects documented their nutritional habits in weighed dietary records. Fasting blood samples were drawn, and feces and urine were quantitatively collected. Dietary phosphorus intake was esti...

One of the questions associated with the development of a cost-effective phosphorus management strategy for a waterbody concerns whether the control program should be based on total phosphorus or on algal available phosphorus entering the waterbody. Until now, eutrophication control programs have been based largely on the control of any form of phosphorus that was amenable to control, irrespect...

736 L ike rowdy bar patrons, centro-somes must be booted from the cell during oogenesis. To achieve this, a cell cycle regulator moonlights as a bouncer for centrosomes, as shown by Kim and Roy on page 751. In most organisms, centrosomes are removed from the developing egg to prevent the fertilized zygote from inheriting redundant sets from both the egg and the sperm. But too many of these micr...

This study uses digital ionosonde data from a cusp latitude station (Cambridge Bay, 77 CGM lat.) to study the convection into the polar cap. Days when the IMF magnetic field was relatively steady were used. On many days it was possible to distinguish an interval near noon MLT when the ionosonde data had a different character from that at earlier and later times. Based on our data, and other pub...

BACKGROUND Serum phosphorus is associated with cardiovascular disease (CVD) in the general population, but may not comprehensively reflect phosphorus homeostasis. Whether urine phosphorus-creatinine ratio (a marker of intestinal absorption) or urine fractional excretion of phosphorus (FEPi; a marker of urinary phosphorus handling) is associated with risk of mortality or CVD is uncertain. STUD...

The effects of phosphorus depletion on cardiac muscle function in six awake dogs were evaluated with surgically implanted transducers to serially measure ascending aortic root blood flow and high fidelity left ventricular pressure. After the animals recovered from surgery, phosphorus depletion was induced by feeding them a synthetic phosphorus-deficient diet plus aluminum carbonate gel for 35 d...
