BACKGROUND:  Modified multivisceral transplantation (MMVTx) refers to the use of a graft that includes all abdominal organs except the liver. The use of this type of transplant in children and adults expanded over the last years with good results. However, long-term survival in experimental models has not been reported. Our aim is to describe in detail some technical modifications of MMVTx to obtain long-term survival. MATERIALS AND METHODS:  Syngeneic (Lewis-Lewis) heterotopic MMVTx was performed in 16 male rats (180-250 g)...

Total knee arthroplasty continues to increase in popularity and remains the most common joint replacement surgery. The success of total knee replacement surgery is attributed to improved outcomes, a better patient experience, and lower cost. Rapid recovery total knee replacement protocols have led to these advances by decreasing length of hospital stay, minimizing readmissions, and reducing the cost of surgery. Rapid recovery total knee replacement pathway efforts should focus on preoperative education, optimization of modifiable risk factors, and identification of patients that may not be suitable for this pathway...

BACKGROUND: Although learning in clinical settings is a key element of nursing education, for many learners these are challenging developmental contexts often marked by isolation and a lack of belongingness. Despite the massive appropriation of mobile instant messaging (MIM) platforms and the connective properties attendant to them, very little is known about their role in and impact on nursing students' clinical learning experiences. APPROACH AND METHODS: To address this gap, the study, which was part of a multinational research project on the use of mobile social media in health professions education in developing countries, examined the use of the instant messaging platform WhatsApp by nursing students during placements and potential associations with socio-professional indicators...

The effects of six imidazolium-based ionic liquids (ILs) with different alkyl chain length ([Cn Mim]Cl, n=2, 4, 6, 8, 10, 12) on the structure and functions of bovine serum albumin (BSA) were studied by multi-spectral methods and molecular docking. ILs with the longer alkyl chain length have the stronger binding interaction with BSA and the greater conformational damage to protein. The effects of ILs on the functional properties of BSA were further studied by the determination of non-enzyme esterase activity, β-fibrosis and other properties of BSA...

A first of its kind hybrid electrocoagulation-filtration prototype unit was fabricated for the removal of fluoride, iron, arsenic and microorganisms contaminated drinking water. The unit comprised of 3 chambers, chamber A consisting of an inlet for the water to be treated and an outlet for the treated water along with one block of aluminum electrodes. Chamber B consisted of ceramic membrane filtration assembly at the bottom over a metallic support which filters the flocs so produced in chamber A and chamber C consisting of space to collect the treated water...

Nursing students' learning process during clinical practice is dependent on the quality of their assessment, and the feedback that is given, however an issue that is very little examined. The aim of this study was to investigate student-preceptor dyads and their experiences of mid-course discussions and final assessment. Data were collected through repeated semi-structured individual interviews with 13 dyads close in time to the assessment discussions, and were analyzed by searching for similarities and differences in their experiences...

The survival rate of vitrified-thawed ovarian tissues after autotransplantation still needs to be improved. Therefore finding an ideal cryoprectant to reduce the damage to ovaries that caused by vitrification will pave the way for application of ovary cryopreservation on clinics. Experiments were conducted to investigate the effect of sodium alginate in cryoprotectant solution on mouse ovaries during the vitrification process. The ovaries obtained from 6-weeks old CD1 were assigned into six groups from A to F...

During labour, the uterus itself is vulnerable to hypoxia/ischemia that can occur with each strong contraction and this may ultimately cause dysfunctional labour in some women. Periods of Intermittent re-oxygenations are beneficial to tissues subjected to hypoxia to wash out metabolic by-products that have been accumulated during hypoxic stresses which may affect the tissue viability. We proposed that short intermittent hypoxic episodes may protect the uterus from subsequent sustained long hypoxia. To investigate this, two sets of experiments were performed on term-pregnant and nonpregnant rat uterine tissues...

In the crust of earth, silicon (Si) is one of the two major elements. For plant growth and development, importance of Si remains controversial due to the widely differences in ability of plants to take up this element. In this paper, pot experiments were done to study Si roles in improving salt, drought or cadmium (Cd) stress tolerance in wheat. Up to full emergence, all pots were watered at 100% field capacity (FC) every other day with nutrient solution without any treatments. Fifteen days after sowing, pots were divided into four plots, each with 40 pots for no stress (control) and three stress treatments; drought (50% FC), salinity (200 mM NaCl) and cadmium (2 mM Cd)...

Long non-coding RNA OIP5-AS1 has been studied in human diseases, including several kinds of cancers. It was not studied or reported in hepatoblastoma, so we chose it to do our research in hepatoblastoma. We thought OIP5-AS1 was oncogenic in hepatoblastoma for the high expression of it in hepatoblastoma tissues and cells. OIP5-AS1 knockdown was carried out in cancer cells. Unsurprisingly, this action was verified to be able to inhibit cell proliferation, metastasis and EMT progress in hepatoblastoma. We then measured the low expression level of miR-186a-5p and the high expression level of ZEB1 in hepatoblastoma tissues and cells...

Physician recommendation for prophylactic surgical fixation of a femur with metastatic bone disease (MBD) is usually based on Mirels' criteria and clinical experience, both of which suffer from poor specificity. This may result in a significant number of these health compromised patients undergoing unnecessary surgery. CT-based finite element analyses (CTFEA) have been shown to accurately predict strength in femurs with metastatic tumors in an ex-vivo study. In order to assess the utility of CTFEA as a clinical tool to determine the need for fixation of patients with MBD of the femur, an ad hoc CTFEA was performed on a retrospective cohort of fifty patients...

Cerebral ischemic and reperfusion injury often accompany with inflammation, and lead to severe neuronal damage, which further result in neurological disorders and memory disorders. In this study, we researched XQ-1H, a novel derivative of ginkgolide B, protecting against ischemic stroke in mice through regulation of microglia polarization. Middle cerebral artery occlusion (MCAO)/reperfusion in mice is applied to mimic ischemic stroke in vivo. Immediately after MCAO, mice are intragastric administrated with different dose (31 or 62 mg/kg) of XQ-1H for one or continuative three days...

Mirror invariance refers to a predisposition of humans, including infants and animals, which urge them to consider mirrored images as corresponding to the same object. Yet in order to learn to read a written system that incorporates mirrored letters (e.g., <b> vs. <d> in the Latin alphabet), humans learn to break this perceptual bias. Here we examined the role visual experience and input modality play in the emergence of this bias. To this end, we tested congenital blind (CB) participants in two same-different tactile comparison tasks including pairs of mirrored and non-mirrored Braille letters as well as embossed unfamiliar geometric shapes and Latin letters, and compared their results to those of age-matched sighted participants involved in similar but visually-presented tasks...

Humans are more accurate at remembering faces from their own relative to a different ethnic group (own-race bias). Moreover, better memory for faces from an observer's own relative to the other-gender (own-gender bias) has also been reported, particularly for female participants. Theoretical explanations for these effects either emphasize differential perceptual expertise or socio-cognitive factors. Importantly, both types of explanations typically assume a single common mechanism for the various biases. The present study examined event-related potentials (ERP) in a combined own-race/own-gender bias experiment...

In the present functional magnetic resonance imaging (fMRI) study, we aimed to evaluate whether distinct regions of the hippocampus were associated with spatial memory for items presented in different locations of the visual field. In Experiment 1, during the study phase, participants viewed abstract shapes in the left or right visual field while maintaining central fixation. At test, old shapes were presented at fixation and participants classified each shape as previously in the "left" or "right" visual field followed by an "unsure"-"sure"-"very sure" confidence rating...

Histories of early life stress (ELS) or social discrimination can reach levels of severity characterized as toxic to mental and physical health. Such toxic social stress during development has been linked to altered acute hypothalamic-pituitary-adrenal (HPA) response to social stress in adulthood. However, there are important individual differences in the size and direction of these effects. We explored developmental, genetic, epigenetic, and contextual sources of individual differences in the relationship between ELS, discrimination, and adult responses to acute social stress in a standard laboratory test...

Serpin families classified serine protease inhibitors regulate various physiological processes. However, there is not study on the role of serpin in immune responses against Spiroplasma eriocheiris as a novel causative pathogen in the Chinese mitten crab, Eriocheir sinensis. In our study, quantitative real-time PCR (qRT-PCR) revealed that the mRNA transcripts of Esserpin-2 were ubiquitous in every tissue, relative higher expression in hepatopancreas, gill and hemocytes, while the intestine, muscle, heart and nerve showed relative lower expression...

The block copolymer VIPER (virus-inspired polymer for endosomal release) has been reported to be a promising novel delivery system of DNA plasmids both in vitro and in vivo. VIPER is comprised of a polycation segment for condensation of nucleic acids as well as a pH-sensitive segment that exposes the membrane lytic peptide melittin in acidic environments to facilitate endosomal escape. The objective of this study was to investigate VIPER/siRNA polyplex characteristics, and compare their in vitro and in vivo performance with commercially available transfection reagents and a control version of VIPER lacking melittin...

Combinations of therapeutic agents could synergistically enhance the response of lung cancer cells. Co-delivery systems capable of transporting chemotherapeutics with different physicochemical properties and with the simultaneous release of drugs remain elusive. Here, we assess the ability of nanoparticles of 30-nm diameter obtained from the self-assembly of hyaluronan-based copolymer targeting CD44 receptors to encapsulate both gefitinib and vorinostat for effective combinational lung cancer treatment. Drug loading was performed by nanoprecipitation...

Based on the intellicage paradigm, we have developed a novel cognitive, emotional and social phenotyping battery that permits comprehensive standardized behavioral characterization of mice in an experimenter-independent social setting. Evaluation of this battery in a large number of male and female C57BL/6 wildtype mice, tested in >20 independent cohorts, revealed high reproducibility of the behavioral readouts and may serve as future reference tool. We noticed robust sex-specific differences in general activity, cognitive and emotional behavior, but not regarding preference for social pheromones...
