Chronic compartment syndromes are a rare, but frequently overlooked cause of pain in the locomotor system. Their aetiology is still not fully elucidated. There is an imbalance of muscle volume and space in the compartment. Thickening of the fascia and decreased elasticity lead to a pathological increase in pressure in the compartment under load. Chronic compartment syndromes are found in the foot, lower leg, thigh, forearm, hand, and even the spine. Bilateral compartment syndromes are very common (80 %). The main symptoms are pain in the compartment under physical activity...

All-inorganic perovskite solar cells provide a promising solution to tackle the thermal instability problem of organic-inorganic perovskite solar cells. Herein, we designed an all-inorganic perovskite solar cell with novel structure (FTO/NiOx/CsPbI2Br/ZnO@C60/Ag), in which ZnO@C60 bilayer were utilized as the electron-transporting layers that demonstrated high carrier extraction efficiency and low leakage loss. Conse-quently, the as-fabricated all-inorganic CsPbI2Br perovskite solar cell yielded the power conversion efficiency (PCE) as high as 13...

Heterotrimeric G protein complexes are molecular switches relaying extracellular signals sensed by G protein-coupled receptors (GPCRs) to downstream targets in the cytoplasm, which effect cellular re-sponses. In the plant heterotrimeric GTPase cycle, GTP hydrolysis, rather than nucleotide exchange, is the rate-limit-ing reaction and is accelerated by a recep-tor-like regulator of G signaling (RGS) protein. We hypothesized that posttransla-tional modification of the Gα subunit in the G-protein complex regulates the RGS-dependent GTPase cycle...

Central insulin resistance (IR) influences striatal dopamine (DA) tone, an important determinant of behavioral self-regulation. We hypothesized that an association exists between the degree of peripheral IR and impulse control, mediated by the impact of IR on brain circuits controlling the speed of executing "go" and/or "stop" responses. We measured brain activation and associated performance on a stop signal task (SST) in obese adults with type 2 diabetes (age, 48.1 ± 6.9 yrs (mean ± SD); BMI, 36...

At present, data on the endocannabinoid system expression and distribution in the pancreatic gland appear scarce and controversial as descriptions are limited to humans and laboratory animals. Since the bovine pancreas is very similar to the human in endocrine portion development and control, studies on the fetal gland could prove to be very interesting, as an abnormal maternal condition during late pregnancy may be a predisposing trigger for adult metabolic disorders. The present investigation studied cannabinoid receptor type 2 presence and distribution in the bovine fetal pancreas towards the end of gestation...

The first example of a frustrated Lewis pair (FLP) solely constructed around transition metal centers is described in this work. We have focused on the established capacity of Au(I) and Pt(0) complexes to act as Lewis acidic and basic fragments, respectively, while employing sufficiently bulky P(t)Bu3 and terphenyl phosphine ligands. This avoids formation of metallic Lewis adducts and confers the Au(I)/Pt(0) pair a remarkable capacity to activate dihydrogen and acetylene molecules in a fashion that closely resembles that of traditional main group FLP systems...

Human birth presents an abrupt transition from intrauterine to extrauterine life. Here we introduce a novel Maturation Index (MI) that considers the relative importance of gestational age at birth and postnatal age at scan in a General Linear Model. The MI is then applied to Diffusion Tensor Imaging (DTI) in newborns for characterizing typical white matter development in neonates. DTI was performed cross-sectionally in 47 neonates (gestational age at birth=39.1±1.6 weeks [GA], postnatal age at scan=25.5±12...

BACKGROUND: Phage genome analysis is a rapidly growing field. Recurrent obstacles include software access and usability, as well as genome sequences that vary in sequence orientation and/or start position. Here we describe modifications to the phage comparative genomics software program, Phamerator, provide public access to the code, and include instructions for creating custom Phamerator databases. We further report genomic analysis techniques to determine phage packaging strategies and identification of the physical ends of phage genomes...

Ion-imprinted polymers (IIPs) have drawn much attention in the selective determination of heavy metals. In this study, 8-hydroxyquinoline-grafted gelatin with different types of functional groups was first introduced as a biomolecular monomer to enhance the selectivity of imprinted cavities. Based on its swelling and film-forming properties, a simple strategy containing formation of the hydrogel film, swelling/folding followed by cross-linking, was proposed to prepare three-dimensional IIPs with high adsorption capacity (235...

Monomeric Hg(II) selenolate complexes derived from 2-phenylbenzamide ligands were prepared by oxidative addition of diselenides [{C6H4(CONR2)Se}2, R = Me, Et, iPr] to elemental Hg and reductive cleavage of the Se–N bond of isoselenazolone derivatives [(NO2)C6H3(CONSe)R, (R = allyl, nbutyl)] followed by the treatment with HgCl2. The complexes have been characterized by multinuclear NMR (1H, 13C and 77Se) spectroscopy and mass spectrometry which suggest the monomeric form of these in solution. The molecular structures of diselenides [C6H4(CONR2)Se]2 and mercury selenolates [Hg{(NO2)C6H3(CONH-C3H5) Se}2], [Hg{C6H4(CONiPr2)Se}2] and [Hg{C6H4(CONMe2)Se}2] were established by a single crystal X-ray diffraction study...

Multiple different reverse total shoulder arthroplasty (rTSA) prosthesis designs are available in the global marketplace for surgeons to perform this growing procedure. Subtle differences in rTSA prosthesis design parameters have been shown to have significant biomechanical impact and clinical consequences. We propose an rTSA prosthesis design classification system to objectively identify and categorize different designs based upon their specific glenoid and humeral prosthetic characteristics for the purpose of standardizing nomenclature that will help the orthopaedic surgeon determine which combination of design configurations best suit a given clinical scenario...

Polycyclic aromatic hydrocarbons (PAH) are ubiquitous environmental pollutants and microbial biodegradation is an important means of remediation of PAH-contaminated soil. Delftia acidovorans Cs1-4 (formerly Delftia sp. Cs1-4) was isolated by using phenanthrene as the sole carbon source from PAH contaminated soil in Wisconsin. Its full genome sequence was determined to gain insights into a mechanisms underlying biodegradation of PAH. Three genomic libraries were constructed and sequenced: an Illumina GAii shotgun library (916,416,493 reads), a 454 Titanium standard library (770,171 reads) and one paired-end 454 library (average insert size of 8 kb, 508,092 reads)...

Seeding cells play an important role in the peripheral nerve damage repair. Seeding cells studied conse- quently in peripheral nerve are Schwann cells, bone marrow mesenchymal stem cells and neural stem cells. Schwann cells, the first seeding cells, are various unique glial cells in the peripheral nervous system, which can form the myelin sheath for insulation and package of the neuron projecting axons in the peripheral nervous system so that the conduction velocity of the nerve signal was accelerated. It can be proved that Schwann cells played an important role in the maintenance of peripheral nerve function and in the regeneration process after peripheral nerve injury...

Automatic tissue segmentation of the neonate brain using Magnetic Resonance Images (MRI) is extremely important to study brain development and perform early diagnostics but is challenging due to high variability and inhomogeneity in contrast throughout the image due to incomplete myelination of the white matter tracts. For these reasons, current methods often totally fail or give unsatisfying results. Furthermore, most of the subcortical midbrain structures are misclassified due to a lack of contrast in these regions...

OBJECTIVE: Carbon monoxide (CO) exposure is still one of the leading causes of unintentional poisonings. Although its neurological sequels have been extensively studied, the knowledge about cytogenetic conse- quences still remains very limited. The aim of this study was to estimate the genotoxic potential of carbon monoxide in the course of acute poisoning. METHODS: The examined group consisted of 73 patients treated because of accidental acute CO poisoning, and 22 healthy control individuals...

With regard to the significant morbidity and mortality due to tuberculosis in lung transplant recipients, the identification of brain-dead organ donors with latent tuberculosis by use of the QuantiFERON TB Gold (QFT-G) test may be of help to reduce the risk of TB reactivation and mortality in lung recipients. This study was conducted in the National Research Institute of Tuber-culosis and Lung Diseases (NRITLD) in Iran, from January to March 2013. A total of 38 conse-cutive brain-dead donors, not currently infected with active tuberculosis, were recruited...

BACKGROUND: In order to help rheumatoid arthritis (RA) patients in carrying out and at-taining relevant self-care behaviors and adaptation to the physical limitations of this dis-ease and, conse-quently, promoting their level of health status, an education program based on the PRECEDE component of the PRECEDE-PROCEED model targeting patients with RA was developed. This paper describes the planning of a RA Patient Education Program (RAPEP) designed to promote their quality of life. METHODS: The development of the program began with a comprehensive review of the li-terature...

The use of antimicrobials has meant for humanity one of the biggest progresses in our recent History and has enhanced an improvement in living conditions (with different nuances depending on the levels of development). Handling of infectious diseases by curing the patient and limiting the transmissions source has been a very remarkable achievement from Public Health, since the second half of the 20th Century. The antibiotic resistance has been recognized with different levels of attention, but it has been acknowledged from the beginning of the Antibiotics era, with different levels of attention...

SUMMARY: The rapid growth of DNA sequencing throughput in recent years implies that graphical interfaces for viewing and correcting errors must now handle large numbers of reads, efficiently pinpoint regions of interest and automate as many tasks as possible. We have adapted consed to reflect this. To allow full-feature editing of large datasets while keeping memory requirements low, we developed a viewer, bamScape, that reads billion-read BAM files, identifies and displays problem areas for user review and launches the consed graphical editor on user-selected regions, allowing, in addition to longstanding consed capabilities such as assembly editing, a variety of new features including direct editing of the reference sequence, variant and error detection, display of annotation tracks and the ability to simultaneously process a group of reads...
