BACKGROUND: Intestinal adaptation in short bowel syndrome (SBS) consists of increased epithelial cells (ECs) proliferation as well as apoptosis. Angiotensin-converting enzyme (ACE) has been shown to regulate ECs apoptosis. In this study, we investigated the effect of ACE inhibition on intestinal adaptation after small bowel resection (SBR) in a rat ...

Research during the past 10-20 years shows that positional therapy (PT) has a significant influence on the apnea-hypopnea index. These studies are predominantly performed as case series on a comparably small number of patients. Still, results have not found their way into the daily diagnostic and treatment routine. An average ...

Chylous ascites (CA) is an unusual complication of pediatric abdominal surgery which can be difficult to manage. Little data are available to guide therapy. We describe the presentation, clinical course and management of two patients, a 7-year-old boy and 2.5-year-old girl, who experienced CA following intraperitoneal renal transplantation. Both cases ...

Although there is considerable interest in how either executive function (EF) or impulsivity relate to addiction, there is little apparent overlap between these research areas. The present paper aims to determine if components of these two constructs are conceptual antipodes--widely separated on a shared continuum. EFs and impulsivities were compared ...

A human immunodeficiency virus-negative 63-year-old male with autoimmune hemolytic anemia presented with decreased vision, photophobia and hearing loss. After initial testing seemed consistent with sarcoidosis, he was found to have disseminated Cryptococcus with a cryptococcoma of the left eye. Treatment with systemic anti-fungal therapy improved the patient's condition.

Introduction: Alzheimer's disease (AD) is a common, progressive neurological disorder whose incidence is reaching epidemic proportions. The prevailing "amyloid cascade hypothesis," which maintains that the aberrant proteolysis of beta-amyloid precursor protein (βAPP) into neurotoxic amyloid beta (Aβ) peptides is central to the etiopathology of AD, continues to dominate pharmacological approaches ...

Following the demise of socialism in 1989, religious identification substantially increased in most countries of Central, East, and Southeast Europe. Considering that there is evidence that religiosity is associated with reduced sexual risk taking among young people, this study explored associations between religiosity-assessed at three different levels (religious upbringing, personal ...

Porphyrin molecules offer immense potential as the light harvesting component of dye-sensitised nanocrystalline TiO(2) solar cells. Synthetic porphyrin dyes were amongst the first dyes trialled for sensitisation of inorganic semiconducting oxides. Today, they exhibit the best performance reported for dye-sensitised solar cells. Accompanying the significant performance improvement over the last ...

To clarify the structure of the muscle hyperaemic response during submaximal exercise in the supine position, we tested the hypotheses that this response measured in human calf muscle is biphasic or triphasic (growth-only) at low-moderate or high forces, respectively. Ten subjects performed four series of 5-min bout of intermittent contractions ...

An efficient and direct approach to β-heteroarylated (C-N bond) ketones is demonstrated. Base promoted redox isomerization of propargyl alcohol to α,β-unsaturated ketone followed by conjugate addition to NH-heteroarenes affords a wide range of β-heteroarylated ketones in good to excellent yields. Aryl, heteroaryl, alkyl C(sp), and terminal alkynes containing unactivated propargyl ...

Large quantities of NO(x) and N(2)O emissions can be produced from biomass burning. Understanding nitrogen behavior during biomass pyrolysis is crucial. Nitrogen in biomass is mainly in forms of proteins (amino acids). Phenylalanine, aspartic acid, and glutamic acid were used as the model compounds for the nitrogen in biomass. Release ...

Passive samplers are often employed to measure ozone concentrations in remote areas such as mountain forests. The potential ozone risk for vegetation is then assessed by calculating the AOT40 exposure index (accumulated hourly ozone concentration exceedances above 40 ppb, i.e. AOT40 = Σ([O(3)] - 40)Δt for any hourly ozone concentration ...

A simple and rapid ion-pair reversed phase high-performance liquid chromatography (IP-RP-HPLC) method was developed to analyse the major impurities of lipophilic-conjugated phosphorothioate oligonucleotides (ODNs), which provided better separation performance than capillary gel electrophoresis and ion exchange chromatograph methods. The study showed that covalent conjugations of lipophilic group (docosanyl, C(22)) to ...

The hippocampus and entorhinal cortex play a pivotal role in spatial learning and memory. The two forebrain regions are highly interconnected via excitatory pathways. Using optogenetic tools, we identified and characterized long-range γ-aminobutyric acid-releasing (GABAergic) neurons that provide a bidirectional hippocampal-entorhinal inhibitory connectivity and preferentially target GABAergic interneurons. Activation of ...

Adler et al. (Reports, 23 September 2011, p. 1750) analyzed the standardized sampling data from 48 herbaceous-dominated plant communities and concluded that "Productivity is a poor predictor of plant species richness" at fine-scale. However, their method was biased toward site-number-dominated plant communities. They also failed to provide enough data for ...

Propionibacterium acnes detection in culture media was previously considered a contamination but recently its infectious role was discovered in post-spinal surgery infections. P. acnes might be introduced during surgery. Its diagnosis is based on non-specific clinical signs, image indications of infection, and the conclusive microbiological sign. Furthermore, its diagnosis is ...

The treatments and prognoses of pelvic organ carcinomas differ, depending on whether the primary tumor originated in the rectum, urinary bladder, prostate, ovary, or uterus; therefore, it is essential to diagnose pathologically the primary origin and stages of these tumors. To establish the panels of immunohistochemical markers for differential diagnosis, ...

We tested whether the administration procedure of quercetin affects its metabolite profile and antihypertensive activity. Spontaneously hypertensive rats (SHR) were randomly assigned to four experimental treatments: (1) 1 mL of 1% methylcellulose by oral gavage and 2% DMSO i.p. (control group); (2) 10 mg kg(-1) quercetin by oral gavage once ...

Topological band insulators have recently been discovered in spin-orbit coupled two-and three-dimensional systems. We theoretically predict a class of topological insulators where interaction effects play a dominant role. In actinide elements, simple rocksalt compounds formed by Pu and Am lie on the boundary between metals and insulators. We show that ...

Giant vertebrates dominated many Pleistocene ecosystems. Many were herbivores, and their sudden extinction in prehistory could have had large ecological impacts. We used a high-resolution 130,000-year environmental record to help resolve the cause and reconstruct the ecological consequences of extinction of Australia's megafauna. Our results suggest that human arrival rather ...

New ratiometric two-photon fluorescent probes are developed from 6-substituted quinolines for biological Zn(2+) detection. They show large red shifts and good ratiometric responses upon Zn(2+) binding. They also exhibit high ion selectivities and large two-photon absorption cross sections at nearly 720 nm. Because the new probes are cell-permeable, they can ...
