Why Should Athletes Brake Fast? Influence of Eccentric Velocity on Concentric Performance During Countermovement Jumps at Different Loads.

Purpose: The aim of the present study was to analyze the effect of different eccentric tempos on eccentric kinetics and kinematics and the subsequent concentric performance when performing countermovement jumps against different loads.

Methods: After 1-repetition-maximum assessment and 2 familiarization sessions, 13 well-trained participants performed, in randomized order, 12 sets (4 tempos × 3 loads) of 4 repetitions of the loaded countermovement-jump exercise. The eccentric tempos analyzed were 5 and 2 seconds, as fast as possible, and accelerated (ie, without pause between repetitions), while the loads used were 30%, 50%, and 70% of 1-repetition maximum.

High-sucrose diet-fed male rats show affectations in pubococcygeus reflex activation and myofiber content.

In males, the function of the pubococcygeus muscle (Pcm) shows a high androgen dependency. High sucrose intake increases testosterone levels in pubertal male rats. We aimed to analyze the Pcm reflex activity and fiber type in response to a 30 % sucrose diet.

A -regulatory lexicon of DNA motif combinations mediating cell-type-specific gene regulation.

Gene expression is controlled by transcription factors (TFs) that bind cognate DNA motif sequences in -regulatory elements (CREs). The combinations of DNA motifs acting within homeostasis and disease, however, are unclear. Gene expression, chromatin accessibility, TF footprinting, and H3K27ac-dependent DNA looping data were generated and a random-forest-based model was applied to identify 7,531 cell-type-specific -regulatory modules (CRMs) across 15 diploid human cell types.

Cyclooctadiene Rh(I) Bis- and Tris(pyrazolyl)aluminate Complexes and Their Catalytic Activity on the Polymerization of Phenylacetylene.

In this work, we report the transfer of alkyl bis- and tris(pyrazolyl)aluminates metalloligands to an electron-rich organotransition metal center. The 16-electron heterobimetallic complexes of rhodium [Rh(COD){Al(Phpz)Me}] () and [Rh(COD){Al(Phpz)Me}] () were obtained by metathesis reaction of the sodium bis- () and tris(pyrazolyl)aluminate () with [RhCl(COD)]. For , H and C NMR in solution along with DFT calculations are consistent with a κ-coordination mode of the bis(pyrazolyl)aluminate to a square-planar Rh(I) center.

Perioperative management of pregnant women undergoing nonobstetric surgery.

Nonobstetric surgery during pregnancy should be avoided if possible, but when surgery is required, an obstetrician should be part of the perioperative team. In general, preoperative assessment is similar regardless of whether a woman is pregnant, but cardiovascular, pulmonary, hematologic, and renal changes of pregnancy can increase surgical risk and must be taken into account. Special management considerations include pregnancy-associated laboratory changes, timing of surgery, anesthesia choice, intubation precautions, patient positioning, preoperative blood typing, intraoperative fetal monitoring, and venous thromboembolism prophylaxis.

Inflammatory cell predominance and patterns in chronic rhinosinusitis with and without nasal polyposis patients.

Objectives: There is interest in identifying chronic rhinosinusitis (CRS) endotypes that align pathophysiology with clinical observation and outcomes. CRS with polyps (CRSwNP) has classically been studied with reference to tissue eosinophilia, but the role of other cellular infiltrates remains uncharacterized. No particular tissue prognosticators have been described for CRS without nasal polyps (CRSsNP).

A structured histopathology-based analysis of surgical outcomes in chronic rhinosinusitis with and without nasal polyps.

Objectives: Structured histopathology reporting has been recently described for detailing immunopathological characteristics of chronic rhinosinusitis (CRS), and can be utilized for subtyping CRS and personalizing management. This study scrutinized elements of structured histopathology to identify characteristics that prognosticate outcomes following endoscopic sinus surgery (ESS) for CRS patients with nasal polyps (CRSwNP) and without nasal polyps (CRSsNP).

Methods: Outcomes following ESS were measured using the patient-reported 22-item sinonasal outcome test (SNOT-22).

Effect of Abscisic Acid (ABA) Combined with Two Different Beekeeping Nutritional Strategies to Confront Overwintering: Studies on Honey Bees' Population Dynamics and Nosemosis.

In temperate climates, beekeeping operations suffer colony losses and colony depopulation of during overwintering, which are associated with biotic and abiotic stressors that impact bees' health. In this work, we evaluate the impacts of abscisic acid (ABA) dietary supplementation on honey bee colonies kept in Langstroth hives. The effects of ABA were evaluated in combination with two different beekeeping nutritional strategies to confront overwintering: "honey management" and "syrup management".

Four labs without previous experience in the dicentric assay participated and four modules of the repository were used.

Factors in delay of diagnosis of gynecologic ureteral injuries at a rural academic hospital.

Introduction And Hypothesis: Ureteral injuries are a source of morbidity, and delays in diagnosis can increase the risk for long-term sequelae. Our aim was to quantify and describe iatrogenic ureteral injuries in a rural tertiary care center. Our secondary goal was to evaluate the impact of delayed diagnosis of ureteral injury on patient outcomes and whether cystoscopy had any influence on these outcomes.

Spatial bias in figure placement in representational drawing: Associations with handedness and script directionality.

Spatial biases in graphomotor production tasks such as figure drawing may reflect biological (cerebral lateralization), biomechanical (limb movement), and/or cultural (reading/writing direction) influences. The present study examined sources of bias in the placement in graphic space of a symmetrical drawn figure (a tree). A previous study using a child sample found an overall leftward placement bias, independent of participants' reading/writing direction experience [Picard & Zarhbouch, 2014.

Physicochemical and rheological properties of purees based on Mafafa (Xanthosoma robustum) and quinoa (Chenopodium quinoa Willd.) with the addition of cryoprotectants.

Growing interest in processed frozen products with similar characteristics to natural products has generated the study of new products in the food industry field. The characteristics of each matrix, the process of elaboration, composition, and structure of the additives and the interactions amongst these modify the food's texture, structure, physical and sensory properties and, hence, interfere directly with consumer acceptance. This research studied the effect of adding cryoprotectors during frozen storage on the rheological, physicochemical, structural, and microbiological properties in a Mafafa-quinoa-olive oil puree.

Mechanical, barrier, and color properties of banana starch edible films incorporated with nanoemulsions of lemongrass ( Cymbopogon citratus) and rosemary ( Rosmarinus officinalis) essential oils.

Edible films are among the most promising fields in food science over the last decade due to their versatility (they can be made from a wide array of materials) and because they can be used as carriers of different active substances, like antioxidants, antimicrobial agents, and essential oils from plants. In the case of the essential oils, their inclusion in edible films is limited by their low water solubility. Nanoemulsions are thermodynamically stable and transparent systems that can be used as a way of incorporating essential oils into edible film matrices.

The influence of Aloe vera gel incorporation on the physicochemical and mechanical properties of banana starch-chitosan edible films.

Background: Aloe vera (AV) gel is a promising material in food conservation, given its widely reported antimicrobial and antioxidant activity; however, its application in the formation of edible films and coatings has been small owing its low film-forming capability. The aim of this study was to investigate the physicochemical properties of film-forming solutions and films prepared using unripe banana starch-chitosan and AV gel at different AV gel concentrations.

Results: Our results showed that AV gel considerably affected the rheological and optical properties of the edible coatings, mainly due to increased amounts of solids brought by the AV gel.

Culture time and reagent minimization in the chemical PCC assay.

The possibility to reduce the culture time and volume of blood and reagents required for the chemical Premature Chromosome Condensation (PCC) assay is demonstrated in this work. Peripheral whole blood was exposed to gamma radiation (1-20 Gy). Lymphocytes were cultured for 40 h, using 50 μl of blood and 450 μl of culture medium.

Automatic Detection of Mitosis and Nuclei From Cytogenetic Images by CellProfiler Software for Mitotic Index Estimation.

Mitotic Index (MI) estimation expressed as percentage of mitosis plays an important role as quality control endpoint. To this end, MI is applied to check the lot of media and reagents to be used throughout the assay and also to check cellular viability after blood sample shipping, indicating satisfactory/unsatisfactory conditions for the progression of cell culture. The objective of this paper was to apply the CellProfiler open-source software for automatic detection of mitotic and nuclei figures from digitized images of cultured human lymphocytes for MI assessment, and to compare its performance to that performed through semi-automatic and visual detection.

Pf4 bacteriophage produced by Pseudomonas aeruginosa inhibits Aspergillus fumigatus metabolism via iron sequestration.

Pseudomonas aeruginosa (Pa) and Aspergillus fumigatus (Af) are major human pathogens known to interact in a variety of disease settings, including airway infections in cystic fibrosis. We recently reported that clinical CF isolates of Pa inhibit the formation and growth of Af biofilms. Here, we report that the bacteriophage Pf4, produced by Pa, can inhibit the metabolic activity of Af biofilms.

A New Cytogenetic Biodosimetry Image Repository for the Dicentric Assay.

The BioDoseNet was founded by the World Health Organization as a global network of biodosimetry laboratories for building biodosimetry laboratory capacities in countries. The newly established BioDoseNet image repository is a databank of ~25 000 electronically captured images of metaphases from the dicentric assay, which have been previously analysed by international experts. The detailed scoring results and dose estimations have, in most cases, already been published.

Particle stresses in dilute, polydisperse, two-way coupled turbulent flows.

Direct numerical simulations are performed of turbulent planar Couette flow which are seeded with two-way coupled particles at low volume concentration. Based on an understanding of the development of particle stress (horizontal momentum carried vertically on average by the particle phase) in monodisperse systems at various particle Stokes numbers, several bidisperse and continuously polydisperse systems are simulated which are chosen to understand how flows containing blends of particle Stokes numbers can be effectively modeled in the dilute regime. Under noninteracting conditions, the particle stresses from particles with different inertia and different feedback stresses are shown to be linearly additive, providing a convenient method for effectively representing dispersed phase stress in polydisperse systems.

Shortening the culture time in cytogenetic dosimetry using PCC-R assay.

The fast assessment of the dose received by exposed persons is crucial in radiological accidents, so the 48 h of cell culture in conventional cytogenetic dosimetry in addition to some limitations after high doses becomes a disadvantage. The premature chromosome condensation (PCC) assay permits to analyse enough cells after high radiation exposure, and the score of PCC-R may reduce the culture time up to 40-42 h. Peripheral whole-blood samples were exposed to 1-10 Gy of gamma radiation and cultured during 40 and 42 h.
