The risk factors for health care–associated pneumonia (HCAP) include hospitalization for 2 or more days within the past 90 days, residence in a nursing home or extended-care facility, home infusion therapy, and long-term dialysis within the past 30 days. Distinguishing between community-acquired pneumonia (CAP) and HCAP is important because of the implications for therapy. Compared with CAP, HC...
Beta-carotene (ß-carotene) is one of many carotenoids found in nature. In the human nutrition field, evidence suggests that higher blood levels of ß-carotene as well as other carotenoids such as alpha-carotene, lycopene, lutein, zeaxanthin, and ß-cryptoxanthin may be associated with lower risk of several chronic diseases. ß-carotene, a-carotene, and ß-cryptoxanthin have pro-vitamin A activity, ...
تشدید رقابت در نظام بانکداری ایران بانکهای بزرگ را در مقابل راهبردهای پارتیزانی بانکهای کوچک آسیبپذیر نموده است. در این فضا حفظ ارتباط بین برند بانک با مشتریان در حفظ سهم بازار بانکهای موجود بسیار موثر است. یکی از شاخصهای قوت ارتباط بانک با مشتریان طنین برند آن است. در این پژوهش تلاش شد تا عوامل تعیین کننده طنین برند بانک صادرات بر اساس الگوی هرم ارزش ویژه برند کلر، ارزیابی شود. پرسشنام...
Background ß-alanine has ergogenic potential based on its relationship with carnosine. Carnosine is rapidly degraded into ß-alanine and histidine as soon as it enters the blood. So there is no advantage to using direct carnosine supplementation. Previous studies have demonstrated that taking ß-alanine orally is effective at increasing intramuscular carnosine levels. The resistance training athl...
A new phenylethanoid glycoside acylated with syringic acid, namely acanmontanoside, was isolated from the aerial portions of Acanthus montanus (Nees). T. Anderson, along with decaffeoylverbascoside, verbascoside, isoverbascoside, leucosceptoside A, (2R)-2-O-ß-D-glucopyranosyl-2H-1,4-benzoxazin-3(4H)-one (HBOA-Glc), (2R)-2-O-ß-D-glucopyranosyl-4-hydroxy-2H-1,4-benzoxazin-3(4H)-one (DIBOA-Glc), (...
The present study was undertaken to investigate the effects of ß-alanine (a glycine agonist), on learning and memory in mice. ß-alanine (5, 10, 20 and 40 mg/kg i.p.) was administered for 6 successive days, to young (3 months old) and aged-mice (16 months old). The learning and memory parameters were assessed, using elevated plus-maze and passive-avoidance apparatus. The effect of ß-alanine (20 ...
PARTICIPANTS RATED THE PERCEIVED complexity and melodiousness of fractal (1/f ) tone sequences with specific ß values. Plotting the mean complexity and melodicity ratings against each other and against ß indicated that: (1) a melody’s spectral power density slope ( ß) can be used as an objective measure of its perceived complexity; (2) ß ≈ 1.50 for optimally preferred melodies; (3) perceived co...
