Altitude is a confounding factor within the Athlete's Biological Passport (ABP) due, in part, to the plasma volume (PV) response to hypoxia. Here, a newly developed PV blood test is applied to assess the possible efficacy of reducing the influence of PV on the volumetric ABP markers; hemoglobin concentration ([Hb]) and the OFF-score. Endurance athletes (n=34) completed a 21 night simulated live high: train low protocol (14h.d-1 at 3000m). Bloods were collected twice pre-altitude, at days 3, 8 and 15 at altitude and 1, 7, 21 and 42 days post-altitude...

Superficial acral fibromyxoma (SAFM) is an uncommon mesencyhmal soft tissue tumor with a predilection for the acral extremites and nail bed involvement. SAFM is diagnosed with clinicopathological and immunohistochemical examination. Awareness of this rare tumor is important because of amounts of benign and malignant neoplasms. We report a case of SAFM in a rare localization in the heel with a new entity on dermoscopy.

OBJECTIVE: The Viatorr stent-graft (W. L. Gore and Associates), specifically made for transjugular intrahepatic portosystemic shunt (TIPS) creation, has significantly improved TIPS patency compared with bare metal stents. Post-TIPS hepatic encephalopathy (HE), however, remains relatively common after TIPS creation. We describe a technique to secondarily restrict a Viatorr stent-graft to treat post-TIPS refractory HE and maintain use of the Viatorr device. CONCLUSION: We show a simple technique to modify the Viatorr stent-graft for TIPS reduction...

In the present study, the core-shell structured RF/PVA nanofibers have been developed and used for the adsorption of As3+ions from the mimicked liquid effluents. Efficient-facile fabrication of the structured nanofibers (300-417 nm diameter) was accomplished using facile electrospinning technique. Chi parameter (χ = 25.56) and free energy of mixing (Emix = 17.19 kcal/mol) calculated via molecular dynamics simulations depicted compatibility of the polymeric system resulting supermolecular core-shell nanofibers, whose adsorption results were also supported by the FE-SEM, FT-IR, and UV-VIS spectroscopy analysis...

To mitigate the effects of heat and drought stress, a better understanding of the genetic control of physiological responses to these environmental conditions is needed. To this end, we evaluated an upland cotton ( Gossypium hirsutum L.) mapping population under water-limited and well-watered conditions in a hot, arid environment. The elemental concentrations (ionome) of seed samples from the population were profiled in addition to those of soil samples taken from throughout the field site to better model environmental variation...

Hematopoiesis is a complex process with a variety of different signaling pathways influencing every step of blood cell formation from the earliest precursors to final differentiated blood cell types. Formation of blood cells is crucial for survival. Blood cells carry oxygen, promote organ development and protect organs in different pathological conditions. Hematopoietic stem and progenitor cells (HSPCs) are responsible for generating all adult differentiated blood cells. Defects in HSPCs or their downstream lineages can lead to anemia and other hematological disorders including leukemia...

OBJECTIVE: We report our experience with surgery in 50 patients with C2 neurinomas. The anatomic subtleties of these discrete forms of tumors and their surgical implications are analyzed. METHODS: During the period 2006-2016, we operated on 50 patients with 55 C2 neurinomas. Type A tumors were located within the spinal canal, type B tumors were located in the lateral gutter, and type C tumors had a paraspinal extension. By working within the dural confines of the tumor and appropriately angulating the microscope, the entire tumor bulk extending into 1 or all 3 compartments was resected...

We have previously reported that the dispersion of spin-lattice relaxation rates in the rotating frame (R1ρ ) of tissue water protons at high field can be dominated by chemical exchange contributions. Ischemia in brain causes changes in tissue pH, which in turn may affect proton exchange rates. Amide proton transfer (APT, a form of chemical exchange saturation transfer) has been shown to be sensitive to chemical exchange rates and able to detect pH changes non-invasively following ischemic stroke. However, the specificity of APT to pH changes is decreased because of the influence of several other factors that affect magnetization transfer...

PURPOSE: To evaluate the ability of spin-lock imaging to detect the uptake of 3-o-methyl-D-glucose (3oMG) in normal brain and brain tumors in animals. METHODS: Measurements of the longitudinal relaxation rate in the rotating frame (R 1ρ ) were made over a range of spin-lock powers in rat brains bearing 9L tumors. The dispersion of R 1ρ values was quantified by ΔR 1ρ , the difference of R 1ρ values acquired with low and high locking powers. The glucose analogue 3oMG was administered intravenously and the differences of ΔR 1ρ values ( ΔR1ρdiff) before and as a function of time after administration were calculated to isolate the contribution of 3oMG to the dispersions, which at high fields primarily reflects chemical exchange effects...

Athletic groin pain (AGP) is a common injury prevalent in field sports. One biomechanical measure that may be of importance for injury risk is stiffness. To date however, stiffness has not been examined in AGP. The primary aim was to determine if AGP affects vertical and joint stiffness and if so, whether successful rehabilitation is associated with a change in stiffness. Sixty-five male patients with AGP and fifty male controls were recruited to this study. Assessment included a biomechanical examination of stiffness during a lateral hurdle hop test...

Drought is the No. 1 factor that limits agricultural production in the world, thus, making crops more drought tolerant is a major goal in agriculture. Many genes with functions in abiotic stress tolerance were identified, and overexpression of these genes confers increased drought tolerance in transgenic plants. The isopentenyltransferase gene (IPT) that encodes a rate limiting enzyme in cytokinin biosynthesis is one of them. Interestingly, when IPT-transgenic cotton was field-tested at two different sites, Texas and Arizona, different results were obtained...

BACKGROUND & AIMS: Myeloid cell leukemia1 (MCL1), a prosurvival member of the BCL2 protein family, plays a pivotal role in human cholangiocarcinoma (CCA) cell survival. We have previously reported that fibroblast growth factor receptor (FGFR) signaling mediates MCL1-dependent survival of CCA cells in vitro and in vivo. However, the mode and mechanisms of cell death in this model were not delineated. METHODS: Human CCA cell lines were treated with the pan-FGFR inhibitor LY2874455 and the mode of cell death examined by several complementary assays...

According to pathogen-avoidance perspectives on disgust, injuries, gore, mutilation, or body-envelope violations elicit disgust because they have infectious potential. Here, an alternative explanation is proposed: People empathically simulate an observed injury, leading to unpleasant vicarious feelings, and for lack of a more accurate word, they describe the feelings as disgust. In Study 1, factor analysis of participants' disgust ratings showed that injury items emerged as a separate factor from pathogen items...
