Pepsin, a digestive enzyme, plays an important role in the metabolism of protein products in the stomach. The pH is regarded as the most pivotal criteria in appraising the pepsin’s enzymatic activity. Pepsin is idle at the physiological pH (7.4) but dynamic in the acidic environments of the stomach (pH 2.0–4.0). Inspir... |
The percentage of complications following an interval or emergency operative interventions in the abdomen is different and depends on several factors: -Proper indication for surgery -Experience of the surgical team, anesthesia -Extent of pathological changes; -patient's general condition (presence of associated disease... |

ABSTRACT This paper studies the equilibrium balking strategies in the single-server Markovian queues with partial breakdowns and interruptible/setup closedown policy. That means the server may fail at any point in time, no matter the server is idle or busy and the service continues at a slower rate instead of stopping ... |
Several investigators have shown that nicotinamide (NA) may increase the tumor blood flow and/or alleviate temporal fluctuations in tumor blood flow and, consequently, increase pO2. However, the mechanisms of these changes in tumor blood flow are not understood, especially because NA lowers the mean arterial blood pres... |
Reducing the cost of manufacturing batteries for electricity storage has led EU Electricity Distributors OD to investment programs in battery storage systems and the supply of electricity stored at daily peak load or in case of damage to the regional power supply consumers over limited time periods. Combined with the p... |
In microeconomics, the strict concavity is a very important property of a production function. In 2010, Avvakumov et al. gave a necessary and sufficient condition for the strict concavity of the Cobb–Douglas and constant elasticity of substitution (CES) production function with at least two inputs. To derive these cond... |
We wished to determine if inhibitors of the complement system are present in different rabbit ocular tissues. Soluble extracts of cornea, vitreous humor and chorioretina in different dilutions were incubated with normal human serum (as source of complement). The ability of the latter to lyse sheep erythrocytes sensitiz... |
The orphan nuclear receptor NR2E3 is a direct transcriptional target of NRL, the key basic motif leucine zipper transcription factor that dictates rod versus cone photoreceptor cell fate in the mammalian retina. The lack of NR2E3 function in humans and in retinal degeneration rd7 mutant mouse leads to increased S-cones... |
BACKGROUND AND OBJECTIVES |
The microvascular circulation plays an important role in bone health. This study examines whether albuminuria, a marker of renal microvascular disease, is associated with incident hip and pelvic fractures. |
DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS |
This study reanalyzed data from the Ongoing Telmisartan Alone and in combination with Ramipril Global End Point Trial/Telmisartan Randomized Assessment Study in Angiotensin-Converting Enzyme Intolerant Subjects with Cardiovascular Disease trials, which examined the impact of renin angiotensin system blockade on cardiov... |
RESULTS |
There were 276 hip and pelvic fractures during a mean of 4.6 years of follow-up. Participants with baseline albuminuria had a significantly increased risk of fracture compared with participants without albuminuria (unadjusted hazard ratio=1.62 [1.22, 2.15], P<0.001; adjusted hazard ratio=1.36 [1.01, 1.84], P=0.05). A d... |
CONCLUSIONS |
Albuminuria, especially macroalbuminuria, and rapid decline of estimated GFR predict hip and pelvic fractures. These findings support a theoretical model of a relationship between underlying causes of microalbuminuria and bone disease.NATURALIZATION OF PLAINS COTTONWOOD (POPULUS DELTOIDES SUBSP. MONILIFERA) ALONG RIVER... |
Abstract Historic botanical surveys documented that the natural distribution of the plains cottonwood (Populus deltoides subsp. monilifera) was limited to semiarid drainages east of the Rocky Mountains. Recently, a number of isolated populations of plains cottonwood have been found along the Kootenai, lower Snake, and ... |
Semiconducting MoS2 monolayers have shown many promising electrical properties, and the inevitable polycrystallinity in synthetic, large-area films renders understanding the effect of structural defects, such as grain boundaries (GBs, or line-defects in two-dimensional materials), essential. In this work, we first exam... |

Abstract The paper presents a new test method for investigations of threshold curves for the resolving power of the eye and for exact measurements of visual acuity. This method measures static visual acuity within confidence limits of 9% compared to the acuity steps in Snellen notation of 33% to 50%. Furthermore, the m... |
Abstract The answer to this provocative question is “no”! This is demonstrated by experiment and analysis for two very different materials – a highly concentrated emulsion and an 8%v/v Kaolin clay suspension. The flow curves of both materials clearly showed a low shear Newtonian asymptote and a pseudoplastic domain. Th... |
the most important aspect of current treatment. Even when more effective treatment methods are discovered, an ethnographic knowledge base will be needed to promote compliance with treatment regimens.

A total of 61 patients, ASA status I–II, were randomly assigned to receive either oral clonidine 100 &mgr;g (n = 29) or placebo (n = 32) before surgery and 24 h after surger... |
OBJECTIVE |
Synthetic cathinones, more commonly known as "bath salts", are synthetic drugs chemically related to cathinone, a psychostimulant found in the khat plant. They are the first most consumed products among new psychoactive substances, which cause psychostimulant and hallucinogenic effects determining a number of fatalitie... |
MATERIALS AND METHODS |
Relevant scientific articles were identified in Medline, Cochrane Central, Scopus, Web of Science and Institutional/government websites up to November 2017 using the following keywords: synthetic cathinones, mephedrone, methylenedioxypyrovalerone, MDPV, methylone, ethylone, buthylone, fatal intoxication, fatalities and... |
RESULTS |
In total, 20 citations met the criteria for inclusion, representing several fatal cases with analytically confirmed synthetic cathinones in biological sample/s of the deceased. The death was attributed to hyperthermia, hypertension, cardiac arrest and more in general to the classic serotonin syndrome. Only rarely did t... |
CONCLUSIONS |
Abuse of synthetic cathinones still represents a serious public health issue. Systematic clinical studies on both the animal and human model are lacking; therefore, the only available data are from the users who experience the possible hazardous consequences. Analytical methodologies for the identification of parent co... |
BACKGROUND |
The present study evaluated the effectiveness of a multidisciplinary earlier discharge model for neonates receiving home enteral nutrition (HEN). |
METHODS |
A retrospective data review and analysis was performed on 183 patients discharged out of the neonatal intensive care unit (NICU) receiving partial oral feeds (PO) and partial HEN from September 2016 to March 2018. These patients were followed in a multidisciplinary clinic led by a pediatric gastroenterologist, a neonat... |
RESULTS |
Of 182 patients, 121 (67%) weaned off HEN with a median time to full PO at 79 days (interquartile range [IQR] 15, 247) and had median PO intake of 20% (0, 43) at time of discharge. When comparing patients who gained 100% PO vs patients who did not wean off HEN, the weaned group consisted of 88% nasogastric tubes, with ... |
CONCLUSIONS |
Our study supports that NICU patients with feeding dysfunction can effectively and safely discharge home earlier while receiving HEN. Our data suggest that a dedicated outpatient clinic can facilitate effective tube weaning in a majority of neonates with complex medical diseases with low rates of adverse events.Crystal... |
