Study shows how to measure energy use, costs in food service.

The cost and the availability of energy resources affect the cost of food service operations. Food service managers need to know the energy consumption and costs associated with preparation of various food products using various types of equipment. One study offers a technique that can enable them to measure these data.

Reducing the transmission of HIV-1: needle bleaching as a means of disinfection.

OBJECTIVE: To review the efficacy, safety, and proper methods for use of bleach (sodium hypochlorite) as a means of needle disinfection. DATA SOURCES: Controlled studies cited in MEDLINE between 1966 and 1999 using indexing terms: needle, bleach, HIV/AIDS, and disinfection. STUDY SELECTION AND DATA EXTRACTION: Studies were categorized based on experimental conditions produced and specific testing procedures used. DATA SYNTHESIS: Used properly, undiluted bleach (sodium hypochlorite 5.25%) appears to be an effective disinfection solution for used needles. Proper needle disinfection with undiluted bleach may reduce the risk of HIV transmission among injection drug users from needle sharing. CONCLUSION: Pharmacists can play a role in reducing HIV transmission among injection drug users by advocating cessation of drug use, drug treatment programs, and avoidance of needle sharing. Pharmacists should be prepared to educate patients who are unwilling to cease illicit drug use or participate in drug treatment programs on the proper methods of bleach disinfection of used needles.

Changes of lipocalin type prostaglandin D-synthase in the seminal plasma of subfertile man.

It was proposed that lipocalin type prostaglandin D synthase (L-PGD-S), a bifunctional protein both synthesizing PGD2 and transporting retinoids and other lipophilic ligands, could be involved in the development and the maturation of sperm. In the present study, the seminal plasma (SP) of 59 adult males was analyzed by standard WHO methods and immunoblotting, using a monospecific polyclonal antibody directed against L-PGD-S. Briefly, aliquots of SP (2.5 microl), were fractionated by polyacrylamide electrophoresis in the presence of sodium dodecyl sulfate, the blots were stained and densitometrically analyzed. To obtain quantitative data, the aliquot of SP was selected within the linear part of the dose/band intensity curve and a proper quality control was analyzed in all blots to normalize the intensity of the bands of different experiments. A significant reduction (p<0.05) of the L-PGD-S levels was observed in severe oligozoospermic patients compared to normozoospermic subjects and a significant correlation between L-PGD-S levels and sperm concentration was found, as reported by other authors. Further studies are warranted to evaluate the possible diagnostic and pharmacological applications of these observations.

[Treatment of male idiopathic sterility with gonadotropin].

The present paper reports our personal data on gonadotropin therapy in patients with idiopathic secretory oligozoospermia due to a low biological activity of LH. In recent years the use of more specific diagnostic procedures, particularly the biological assay of gonadotropins, and a better knowledge of the biological and pharmacological properties of hormones, increased the indications of hormonal treatment in male infertility, not only through the synthesis of new active compounds but mainly broading the field of application of gonadotropins.
