BACKGROUND Parenteral nutrition (PN) is a costly therapy that can also be associated with serious complications. Therefore, efforts are focusing on reducing rate of complications, and costs related to PN. OBJECTIVE The aim was to analyze the effect of the implementation of PN standardization on costs and quality criteria. Secondary aim was to assess the use of individualized PN based on patie...
For a path Pn of order n, Chartrand et al. [3] have given an upper bound for radio k-chromatic number when 1 ≤ k ≤ n−1. Liu and Zhu [7] have determined the exact value of radio (n−1)-chromatic number of Pn, namely radio number, rn(Pn), when n ≥ 3. Khennoufa and Togni [5] have given the exact value of radio (n − 2)-chromatic number of Pn, namely antipodal number, ac(Pn), when n ≥ 5. Kola and Pan...
OBJECTIVE To determine whether glutamine (GLN)-supplemented parenteral nutrition (PN) improves clinical outcomes in surgical intensive care unit (SICU) patients. SUMMARY BACKGROUND DATA GLN requirements may increase with critical illness. GLN-supplemented PN may improve clinical outcomes in SICU patients. METHODS A parallel-group, multicenter, double-blind, randomized, controlled clinical t...
تحقیق در ساختارهای پوسته و گوشته فوقانی در فلات ایران بسیار محدود بوده و در این زمینه کار اندکی صورت گرفته است. در این مقاله یک هدف اصلی مد نظر قرار دارد و آن به تصویر کشیدن سرعت های pn و sn در زیر فلات ایران، به منظور آزمایش کردن مدل های سه بعدی گوشته و به دست آوردن روشی جدید و آزمودن آن برای به دست آوردن تصحیح زمان های سیر pn و sn که متشابه سه بعدی منحنی های زمان سیر مدل های یک بعدی اند. روش ...
Generally, primed seeds produce larger and heavier plants than non-primed seeds. This may be simply due to rapid emergence and extension of leaf growth, or the influence of other physiological processes. The effect of seed pretreatment with salicylic acid (SA) on some physiological and photosynthetic characteristics of the safflower seedlings, cv. Goldasht, was examined under field condition. T...
In this paper we study ultraflat sequences (Pn) of unimodular polynomials Pn ∈ Kn in general, not necessarily those produced by Kahane in his paper [Ka]. We examine how far is a sequence (Pn) of unimodular polynomials Pn ∈ Kn from being conjugate reciprocal. Our main results include the following. Theorem. Given a sequence (εn) of positive numbers tending to 0, assume that (Pn) is a (εn)-ultraf...
Recently, it was shown that the exposure to the potent hop phytoestrogen 8-prenylnaringenin (8-PN) depends on intestinal bacterial activation of isoxanthohumol (IX), but this occurs in only one-third of tested individuals. As the butyrate-producing Eubacterium limosum can produce 8-PN from IX, a probiotic strategy was applied to investigate whether 8-PN production could be increased in low 8-PN...
In the present article we study the asymptotic behavior of the sums n≤x cn+1 pn+1 − cn pn and n≤x pn+1 cn+1 − pn cn , and of the series ∞ n=1 cn+1 pn+1 − cn pn α , where p n denotes the n-th prime number while c n stands for the n-th composed number.
INTRODUCTION Parenteral nutrition (PN) is indicated for patients who are unable to progress to oral or enteral nutrition. There are no local studies done on estimating the cost of PN in acute settings. The aims of this study are to describe the demographics, costs of PN and manpower required; and to determine the avoidable PN costs for patients and hospital on short-term PN. MATERIALS AND MET...
Peripheral neuroepitbelioma (PN) is a rare highly malignant tumor, classified in the group of small round cell tumors. We report eight cases of PN, based on histologic appearance and immunohistochemical staining for neuron-specific enolase (NSE). Electron microscopy was also performed in three cases. The tumors exhibited rapid local growth, leading to limb amputation in five cases. Histolo...
