Modelling the comparative costs of Namaste Care: results from the namaste care intervention UK study
Purpose The purpose of this paper is to populate a theoretical cost model with real-world data, calculating staffing, resource and consumable costs delivering Namaste Care Intervention UK (NCI-UK) sessions versus “usual care” for care home residents advanced dementia. Design/methodology/approach Data from five homes NCI-UK populated the generate session- resident-level costs. Comparator usual w...
Some evidence links cancer outcomes to place of service, but the influence of NCI (National Cancer Institute) cancer centers on outcomes has not been established. We compared mortality for NCI cancer center attendees versus nonattendees. This retrospective cohort study included individuals with incident cancers of the lung, breast, colon/rectum, or prostate from 1998 to 2002 (N = 211,084) from ...
The pathogenesis of pain in irritable bowel syndrome (IBS) is poorly understood and treatment remains difficult. The present study was designed to investigate roles of adrenergic signaling and the endogenous hydrogen sulfide producing enzyme cystathionine β-synthetase (CBS) in a previously validated rat model of IBS induced by neonatal colonic inflammation (NCI). Here we showed that NCI-induced...
BACKGROUND AND PURPOSE Neuropsychological changes that precede a diagnosis of vascular cognitive impairment (VCI) and the differences between preclinical VCI and Alzheimer disease (AD) are not well understood. We compared the neuropsychological performances of people with incident VCI, incident AD, and no cognitive impairment (NCI) 5 years before their clinical diagnoses. METHODS The Canadian...
OBJECTIVES Large unselected studies on representative samples of HIV-infected patients with a whole battery of neuropsychological tests and cerebral MRI scan are required to assess the frequency of neurocognitive impairment (NCI), the determinants of mild neurocognitive disorders (MNDs), or HIV-associated dementia (HAD) and the relationship between NCI and MRI scan findings. METHODS Investiga...
Trastuzumab has been successfully employed for the treatment of Her-2-positive gastric cancer. However, there are problems with both primary and secondary resistance to trastuzumab. In this study, we employed the human gastric carcinoma cell line NCI-N87 with high Her-2 expression to create trastuzumab-resistant NCI-N87/TR cells by stepwise exposure to increasing doses of trastuzumab. Western b...
در این پژوهش، ابتدا ساختارهای بهینه¬شده برهمکنش¬ غیرپیوندی نانولوله¬های کربنی ساده و دوپه شده با یک و دو اتم گوگرد با مولکول¬های متانول، متان¬تیول، آب و دی¬هیدروژن سولفید در دو موقعیت انتهای بسته نانولوله و بالای بدنه آن با 80 اتم کربن و 10 اتم هیدروژن مورد بررسی پارامتری، انرژی¬های برهمکنشی در فاز گاز و حلال¬های بنزن، کلروفرم و سیکلوهگزان توسط مدل pcm، بارهای اتمی و انرژی اغتشاشی مرتبه دوم nbo...
The cytocidal effect of pyrrolidine dithiocarbamate (PDTC) was investigated by focusing on cell viability, cell cycle arrest and apoptosis induction in small-cell lung cancer (SCLC) cell lines (NCI-H196 and NCI-H889). PDTC exhibited a much stronger dose-dependent cytotoxic activity against NCI-H196 compared to NCI-H889, while no such activity was observed in normal human embryonal lung fibrobla...
Non-covalent interactions (NCI) define the rules underlying crystallisation, self-assembly and drug-receptor docking processes. A novel NCI descriptor, based on the reduced electron density gradient (RDG), that enables easy visualisation of the zones of the electron density (ED) involved in either the supposedly attractive (dispersive, hydrogen bonding) or allegedly repulsive (steric) intermole...
در تئوری حلقه های جابجایی مشخصهء هر دامنهء ددکینداین است که هر ایده آل آن حاصل ضرب ایده آلهای اول است . در این رساله ما برآنیم که این خاصیت را به کلاسی از حلقه های نابجایجایی نوتری گسترش دهیم . و ما در بخش اول از فصل سوم رسالهء ثابت می کنیم که اگرr حلقهء اول نوتری و با اتحاد کثیرالجمله ای و هر ایده آل r حاصل ضرب ایده آلهای اول باشد آنگاه r یک حلقهء ددکینداول است (1-10و3) اما در یک قلمرو صحیح جا...
