In the current study a new recyclable aminated hyper-cross-linked polymeric adsorbent (A-HPA) was prepared for effective removal of DOM from BTCW. Possibly benefited from its unique structure of polystyrene matrix, sufficient aminated groups and high specific surface area, A-HPA could remove DOM from BTCW through the synergetic effect of π-π interactions, acid-base interactions and micropore filling, and exhibited the highest removal efficiency than the other adsorbents. Moreover, the exhausted A-HPA was amenable to effective regeneration by using acid and alkaline solution, allowing for repeated use with a constant removal efficiency...

Segmented filamentous bacterium (SFB) a gram-positive, anaerobic, and intestinal commensal organism directly influencesthe development of Th17 helper cells in the small intestine of mice. In NOD mice, SFB colonization interferes with the developmentof type 1 diabetes (T1D), a T-cell-mediated autoimmune disease, suggesting that SFB may influence Th17 cells to inhibit Th1populations associated with the anti-β-cell immune response. This effect is a serious concern for investigators who use NOD micefor diabetes research because the expected incidence of disease decreases markedly when they are colonized by SFB...

In this study, palm oil mill sludge was used as a precursor to prepare biochar using conventional pyrolysis. Palm oil mill sludge biochar (POSB) was prepared at different preparation variables, i.e., heating temperature (300-800 °C), heating rate (10-20 °C/min) and holding time (60-120 min). The prepared biochars were tested for sulfur dioxide (SO2) adsorption in a fixed bed reactor using 300 ppm of SO2 gas at 300 ml/min (with N2 gas as balance). Response surface central composite experimental design was used to optimize the production of biochar versus SO2 removal...

Myocardial infarction, i.e., heart attack, is a fatal condition which is on the increase all over the world. It is reported that a large number of heart attack occur in morning hours which are attributable to platelet aggregation. Chronotherapy at this stage can be crucial. Clopidogrel bisulfate (CLB) is an antiplatelet agent and has become a drug of choice for prevention of heart attack. It is soluble in acidic pH and has a narrow absorption window. So, its long residence time in stomach is desirable. Therefore, a novel high density tablet was developed comprising multiparticulate pellets with pulsatile release necessary to maintain chronotherapy of heart attack...

BACKGROUND: Delays in patient transfers are associated with worse outcomes for some neurosurgical conditions. One of the primary causes of transfer delay is lack of neurosurgery ICU bed availability. In this study, we characterize the results of implementing an interhospital transfer protocol to reduce unnecessary transfers and improve bed availability. METHODS: A transfer protocol was implemented in July 2012 at the Bellevue Hospital Department of Neurosurgery that screened for and prevented transfer of low-risk patients that were unlikely to require specialized inpatient neurosurgical care...

The C-Pulse is a novel extra-aortic counter-pulsation device to unload the heart in patients with heart failure. Its impact on overall hemodynamics, however, is not fully understood. In this study, the function of the C-Pulse heart assist system is implemented in a one-dimensional (1-D) model of the arterial tree, and central and peripheral pressure and flow waveforms with the C-Pulse turned on and off were simulated. The results were studied using wave intensity analysis and compared with in vivo data measured non-invasively in three patients with heart failure and with invasive data measured in a large animal (pig)...

BACKGROUND: In Japan, the revision of the fee schedules in 2006 introduced a new category of general care ward for more advanced care, with a higher staffing standard, a patient-to-nurse ratio of 7:1. Previous studies have suggested that these changes worsened inequalities in the geographic distribution of nurses, but there have been few quantitative studies evaluating this effect. This study aimed to investigate the association between the distribution of 7:1 beds and the geographic distribution of hospital nursing staffs...

BACKGROUND: The Yale New Haven Readmission Risk Score (YNHRRS) for pneumonia is a clinical prediction tool developed to assess risk for 30-day readmission. This tool was validated in a cohort of Medicare patients; generalizability to a broader patient population has not been evaluated. In addition, it lacks indicators of functional status or social support, which have been shown to be predictors of readmission in other studies. OBJECTIVE: To evaluate the generalizability of the YNHRRS for pneumonia in a general population of hospitalized patients, and assess the impact of incorporating measures of functional status and social support on its predictive value...

  The single-stage deammonification moving bed biofilm reactor (MBBR) is a process for treating high strength nitrogen waste streams. In this process, partial nitritation and anaerobic ammonia oxidation (anammox) occur simultaneously within a biofilm attached to plastic carriers. An existing tank at the James River Treatment Plant (76 ML/d) in Newport News, Virginia was modified to install a sidestream deammonification MBBR process. This was the second sidestream deammonification process in North America and the first MBBR type installation...

BACKGROUND: Reducing unplanned hospital admissions is a key priority within the UK and other healthcare systems, however it remains uncertain how this can be achieved. This paper explores the relationship between unplanned ambulatory care sensitive condition (ACSC) admission rates and population, general practice and hospital characteristics. Additionally, we investigated if these factors had a differential impact across 28 conditions. METHODS: We used the English Hospital Episode Statistics to calculate the number of unplanned ACSC hospital admissions for 28 conditions at 8,029 general practices during 2011/12...
