Sixty-four pork loins were randomly assigned to one of four treatments to evaluate the use of alkaline electrolyzed reduced water as a replacement for traditional enhancement solutions. Treatments included: alkaline electrolyzed reduced water (EOH; pH≈11.5), EOH plus 2.5% potassium-lactate (EOK), industry standard (IS; 0.35% sodium tri-polyphosphate, 0.14% sodium chloride, 2.5% potassium-lactate), and no enhancement (CON). After enhancement (targeting 110%) and rest period, chops were cut (2.54-cm) to test treatment effects on water holding capacity, Warner-Bratzler shear force (WBSF), and sensory attributes...

In the study of shifting cultivation systems, fallow duration is seen as the key determinant of vegetation and soil dynamics: long fallows renew soil fertility, biomass and biodiversity. However, long fallow systems are increasingly replaced around the world with short-medium fallow systems, and awareness is growing of the need to look across multiple (not just single) crop-fallow cycles to accurately understand observed soil and vegetation patterns. In a study from Peru that builds on field-level land-use histories (50+ years), we found that over multiple crop-fallow cycles, farmer's cropping practices mattered more than fallow duration for biodiversity and soil fertility...

Research describing the epidemiology of antibiotic resistant microbes is vital to the proactive development of new antimicrobial agents. In the last years, CTX-M extended-spectrum β-lactamases (ESBLs) have emerged worldwide and have replaced classical TEM and SHV-type ESBLs in many countries. CTX-M-15 is currently the most frequent, with a pandemic distribution, and its rapid spread is facilitated by incorporation of resistance genes in mobile genetic elements. The ESBL is efficacious in Gram-negative bacteria and thus closely associated with nosocomial environments, often colonizing the intestines, particularly in older and dependent patients...

BACKGROUND: Affecting 19% of women, postpartum depression is a major concern to the immediate health of mothers and infants. In the longterm, it has been linked to the development of early-onset asthma at school entry, but only if the depression persists beyond the postnatal period. No studies have tested whether associations with postpartum depressive symptoms and early-onset asthma phenotypes persist into later school age. OBJECTIVE: To determine associations between maternal postpartum depressive symptoms and childhood asthma between the ages of 5-10 by using a nested longitudinal design...

Hydroxymethylcytosine (hmC or 5-hmC) is a nitrogen base occurring as a result of cytosine methylation followed by replacing a methyl group with a hydroxyl group through active oxidation. 5-hmC is considered to be one of the forms of epigenetic modification and is suggested as an intermediate step in a semi-active loss of DNA methylation mark. 5-hmC plays an important role in the epigenetic regulation of gene expression in animals, although its role in plants remains controversial. Here, we present a colorimetric method of quantification of 5-hmC using Brassica rapa DNA...

Anterior tibial tubercle (ATT) osteotomy facilitates exposure in knee arthroplasty. However, it is not without complications. We have introduced some technical modifications that reduce the surgical aggression by designing a short osteotomy that does not invade the intramedullary canal, and synthesizing it with three cerclage wires with a particular layout that increases the solidity of the system. A retrospective review was performed on the surgical revision of total knee replacement cases intervened in our center that required an ATT osteotomy from February 2014 to February 2015, and who had a minimum clinical follow-up of 12 months...

To assess the long-term safety of administering growth hormone (GH) in patients with GH deficiency due to treatment for childhood medulloblastoma and primitive neuroectodermal tumor (PNET). Data were retrospectively retrieved on children receiving GH supplementation, assessing their disease-free and overall survival outcomes and risk of secondary malignancies using Kaplan-Meier and Cox models. Overall 65 children were consecutively collected from May 1981 to April 2013. All patients had undergone craniospinal irradiation (total dose 18-39 Gy), and subsequently received GH for a median (interquartile range, IQR) of 81 (50...

The toxicity of gadolinium is reduced by chelating agents that render this heavy metal into contrast complexes used for medical magnetic resonance imaging. However, the dissociation of gadolinium chelates is known to generate Gd(3+) ions, the cellular toxicity of which has not been tested in details. The cytotoxic effects of Gd(III) ions were evaluated by monitoring the proliferation, measuring the cellular motility and following chromatin changes in various cell lines upon Gd(3+) treatment. Measurements applied long-term scanning microscopy and a perfusion platform that replaced the medium with test solutions, bypassed physical contact with the cell culture during experiments, and provided uninterrupted high time-resolution time-lapse photomicrography for an extended period of time...

Chondrogenesis in vivo is precisely controlled in time and space. The entire limb skeleton forms from cells at the core of the early limb bud that condense and undergo chondrogenic differentiation. Whether they form stable cartilage at the articular surface of the joint or transient cartilage that progresses to hypertrophy as endochondral bone, replacing the cartilage template of the skeletal rudiment, is spatially controlled over several days in the embryo. Here, we follow the differentiation of cells taken from the early limb bud (embryonic day 11...

Hypopituitarism has been associated with an increased mortality, which may be due to untreated growth hormone (GH) deficiency but also to the various underlying disorders. We therefore analysed mortality in patients with only one underlying disorder, non-functioning pituitary adenoma (NFPA), with and without GH replacement therapy (GHRT). Patients with NFPA in the western region of Sweden, 1997-2011, were identified through the National Patient Registry and cross-referenced with several National Health Registries...

BACKGROUND: Troubleshooting of deep brain stimulators (Activa SC/PC/RC Medtronic PLC) sometimes results in a decision to replace a tunneled stretch-coil extension cable. We present a simple technique to accomplish this atraumatically without a tunneling tool. OBJECTIVES: In the treatment of patients with deep brain stimulators, complication avoidance and efficiency of operative time are paramount. We sought to find the most safe, effective, and rapid method for performing the conceptually-simple yet technically-nuanced act of replacing lead extension cables...

BACKGROUND: In Rathke cleft cysts (RCCs), inflammation by the cyst contents infrequently spreads to the surrounding structures. Calcification, which is regarded as a consequence of chronic inflammation of the cyst wall, can rarely be found in RCCs, and moreover, ossification is extremely rare. CLINICAL PRESENTATION: A 60-year-old woman presented with headaches, fatigue and weight loss due to panhypopituitarism. Magnetic Resonance imaging revealed a mass lesion in the sellar region, which was comprised of two different parts, with hypointensity anteriorly and hyperintensity posteriorly on T1-weighted image (WI), and the rim with significant hypointensity entirely on T2-WI...

The degradation of histamine catalyzed by the SAM-dependent histamine N-methyltransferase (HNMT) is critically important for the maintenance of neurological processes. Recently, two mutations in the encoding human gene were reported to give rise to dysfunctional protein variants (G60D and L208P) leading to intellectual disability. In the present study, we have expressed eight L208 variants with either apolar (L208F and L208V), polar (L208N and L208T) or charged (L208D, L208H, L208K and L208R) amino acids to define the impact of side chain variations on protein structure and function...

Dehydroquinase (3-dehydroquinate dehydratase, DHQD, EC catalyzes the conversion of dehydroquinate to dehydroshikimate. DHQD from Acinetobacter baumannii (AbDHQD) was cloned, expressed and purified to homogeneity. The binding studies showed that two compounds quinic acid and citrazinic acid bound to AbDHQD at micromolar concentrations. AbDHQD was crystallized using 30% PEG-3350, 50mM tris-HCl and 1.0M MgSO4 at PH 8.0. Crystals of AbDHQD were stabilized with 25% glycerol for data collection at 100K...

In this paper we report differential decoding of the ultradian corticosterone signal by glucocorticoid target tissues. Pulsatile corticosterone replacement in adrenalectomised rats resulted in different dynamics of Sgk1 mRNA production, with a distinct pulsatile mRNA induction profile observed in the pituitary in contrast to a non-pulsatile induction in the prefrontal cortex. We further report the first evidence for pulsatile transcriptional repression of a glucocorticoid-target gene in vivo, with pulsatile regulation of Pomc transcription in pituitary...

INTRODUCTION: Teeth affected by combined endodontic-periodontal lesions are usually considered by all prognosis classifications as hopeless teeth. The development of new biomaterials combined with modern endodontic and periodontal regeneration techniques may improve dental prognosis and maintain the affected teeth. Moreover, 1 of the replacement options for those teeth, dental implants, has shown an increasing number of biological and technical complications. METHODS: Five patients were included in this case series study...

PURPOSE: With the increase of treatment complexity, enhancing safety is a key concern in radiation oncology. Beyond the involvement of the healthcare professional, patient involvement and empowerment could play a major role in that setting. We explored how patients perceived and fulfilled that role during their radiation treatment. MATERIALS AND METHODS: A voluntary and anonymous questionnaire was administered to all patients treated in our department between November 2013 and May 2014...

Using molecular modeling and rationally designed structural modifications, the multi-target structure-activity relationship for a series of ranitidine analogs has been investigated. Incorporation of a variety of isosteric groups indicated that appropriate aromatic moieties provide optimal interactions with the hydrophobic and π-π interactions with the peripheral anionic site of the AChE active site. The SAR of a series of cyclic imides demonstrated that AChE inhibition is increased by additional aromatic rings, where 1,8-naphthalimide derivatives were the most potent analogs and other key determinants were revealed...

STATEMENT OF PROBLEM: The whitish color of zirconia (ZrO2) abutments offers favorable esthetics compared with the grayish color of titanium (Ti) abutments. Nonetheless, ZrO2 has greater opacity, making it difficult to achieve natural tooth color. Therefore, lithium disilicate (LaT) abutments have been suggested to replace metal abutments. PURPOSE: The purpose of this in vitro study was to evaluate the fracture strength and failure mode of single-tooth implant restorations using ZrO2 and LaT abutments, and to compare them with titanium (Ti) abutments...

Ion imprinted polymers (IIPs) specific to lanthanides were synthesized using neodymium ions (Nd(3+)) as template ions. Nd(3+) ions form binary complex ions with 5,7-dichloroquinoline-8-ol (DCQ) or vinylpyridine (VP), or ternary complex ions with both DCQ and VP in 2-methoxyethanol, before copolymerization in the presence of styrene and divinylbenzene as monomer and cross-linker, respectively. DCQ was expected to be trapped in the synthesized polymers pores. The template ion removal was then optimized. For the first time, the DCQ leakage was determined by HPLC-UV during the template removal and the sedimentation steps before solid-phase extraction (SPE) packing...
