The associations between obesity and Alzheimer's disease (AD) at different ages have been debated. Recent evidence implied the protective effects of metabolically healthy on AD. We hypothesized that lipids could mitigate detrimental impacts AD pathological changes among individuals in late life. In this study, a total 604 participants with normal cognition were included from Chinese Biomarker L...
The possibility of basing the security of cryptographic objects on the (minimal) assumption that NP ⊈ BPP is at the very heart of complexity-theoretic cryptography. Most known results along these lines are negative, showing that assuming widely believed complexity-theoretic conjectures, there are no reductions from an NP-hard problem to the task of breaking certain cryptographic schemes. We mak...
BACKGROUND The most accepted means of evaluating the response of a patient with cervical spondylomyelopathy (CSM) to treatment is subjective and based on the owner and clinician's perception of the gait. OBJECTIVE To establish and compare kinetic parameters based on force plate gait analysis between normal and CSM-affected Dobermans. ANIMALS Nineteen Doberman Pinschers: 10 clinically normal...
BACKGROUND Reductions in detrusor shortening velocity and detrusor contractility have been observed in association with aging. The reasons for these changes are unclear. METHODS We examined the isometric and isotonic responses of detrusor, taken from the bladder body, to adenosine 5'-triphosphate (ATP), noradrenaline (NA), serotonin, and acetylcholine (Ach) in vitro, using bladders from young...
This randomized, noninferiority (NI), global, phase 3 study evaluated the efficacy and safety of bendamustine plus rituximab (BR) vs a standard rituximab-chemotherapy regimen (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone [R-CHOP] or rituximab plus cyclophosphamide, vincristine, and prednisone [R-CVP]) for treatment-naive patients with indolent non-Hodgkin's lymphoma...
از آنجا که انرژی خورشید یکی از شناخته شده ترین منابع مهم انرژی تجدیدپذیر می باشد راهکارهای افزایش جذب انرژی خورشیدی نقش قابل توجهی را در اثربخشی سیستم گردآورنده گرمایی ایفا می کند. هدف از این مطالعه تحلیل تجربی عملکرد گردآورنده جذب مستقیم خورشیدی با استفاده از نانوسیال نانوصفحات گرافن اکساید بر پایه آب دیونیزه می باشد. درصد وزنی گرافن اکساید در سیال پایه آب دیونیزه به ترتیب درصدهای 005/0 ، 015/...
Starch phosphorylase has been isolated from cabbage (Elephantopus scabar) leaves and partially purified using ammonium sulfate fractionation. The partially purified enzyme was desalted using SephadexG-25 chromatography. In the direction of polysaccharide synthesis, the enzyme showed optimum activity at pH 6.0 with two half pH optima at pH 5.3 and pH 7.1 whereas in the direction of glucose-1-pho...
1092-5171/04/3102-0225 ABSTRACT: The purpose of this study was to investigate the accuracy of the proprioceptive system in swallowing as compared to fist clenching. The role of surface electromyography (SEMG) biofeedback in replicating motor strength was also evaluated. It was hypothesized that (a) strength of muscle contraction during swallowing would be less accurately replicated than in a fi...
In predicate encryption, a ciphertext is associated with a descriptive attribute value x in addition to a plaintext μ, a secret key is associated with a predicate f . The decryption returns plaintext μ if and only if f(x) = 1. Moreover, the security guarantees that an adversary learns nothing about the attribute x or the plaintext μ, given arbitrary many secret keys that are not authorized to d...
