Long-term effects of giving nursing home residents bread fortified with 125 microg (5000 IU) vitamin D(3) per daily serving.

Background: In older adults, a serum 25-hydroxyvitamin D [25(OH)D] concentration >75 nmol/L lowers the risk of fracture. An oral intake of 125 microg (5000 IU) vitamin D(3)/d may be required to achieve this target.

Objective: The objective was to characterize the safety and efficacy of fortifying bread with a biologically meaningful amount of vitamin D(3).

Evaluation of the effect of the concentration of plasticizer di(2-ethylhexyl) phthalate on the quantity of residual monomer vinyl chloride in PVC chest drainage tubes.

The effect of amount of plasticizer di(2-ethylhexyl) phthalate (DEHP) amount on the amount of residual monomer vinyl chloride (VC) was determined in samples of plasticised polyvinyl chloride (PVC) with different concentration of plasticiser (22.32-33.05%), before and after sterilisation by a titrimetric method.

Histochemical study on the activity of some oxidative and hydrolytic enzymes in the normal human endometrium blood vessels and at various intervals after applying the intra uterine contraceptive device.

The paper intends to study the cytoenzymological modifications of the human endometrium blood vessels after applying the intrauterine contraceptive device for a long period of time. The results were different according to the: type of the enzyme-ATP-ase, Lactatdehydrogenase, Leucineaminopeptidase, NADH2-citochrome-c-reductase, the components of the blood vessel wall (intima, media, adventitia), the blood vessel diameter, the hormonal cyclic stage.
