Transfer of Microsatellite Loci For The Tropical Tree Prunus africana (Hook. f.) Kalkman
Authors: Cavers S. , Munro R. C. , Kadu  , Konrad  
Published: October 2017

Abstract
Using databases of previously published primers, we optimised six nuclear microsatellite markers for Prunus africana for the purposes of studying spatial genetic structure and gene flow. To assess variability, these and three previously transferred loci were screened in populations from Kenya and South Africa. Across both populations most loci were polymorphic, with the exception of a single locus which failed to amplify in the South African samples, exhibiting between 2 and 22 alleles and levels of expected heterozygosity (He) ranged from 0.059 to 0.932. Departures from Hardy-Weinberg equilibrium were detected for all loci but not for all populations. The estimated null allele frequency was very low to moderate and no evidence for linkage disequilibrium was detected.

Abstract
Chiarlitti, NA, Delisle-Houde, P, Reid, RER, Kennedy, C, and Andersen, RE. Importance of body composition in the national hockey league combine physiological assessments. J Strength Cond Res 32(11): 3135–3142, 2018—The National Hockey League (NHL) combine was designed to assess draft-eligible players based on body composition, speed, power, and strength. The importance of body composition in the battery of combine physical tests was investigated, and differences in results based on position were explored. Thirty-seven elite male Canadian university hockey players (age = 22.86 ± 1.55 years, mass = 87.21 ± 6.52 kg, and height = 181.69 ± 6.19 cm) participated in the study at the beginning of their hockey season. All participants underwent physical testing (as outlined in the 2016 NHL combine) and 1 total body dual energy x-ray absorptiometry scan to measure body composition. Partial correlations (controlling for body mass) were used to explore the relationship among body composition measures (body fat percentage, visceral fat, body mass index, lower lean tissue mass, upper lean tissue mass, upper fat mass, and lower fat mass) with NHL fitness tests (bench press, pull-ups, grip strength, long jump, proagility, vertical jump, V̇o
2max, and the Wingate Anaerobic Test). In 4 of the 6 strength/power tests (Wingate Anaerobic Test, long jump, bench press, and both grip strengths), lower and upper lean tissue mass explained significant amounts of variance. Although forwards and defensemen significantly differed in right grip strength and proagility left scores, they did not differ in regard to any body composition variables. Body composition has a significant influence on several combine-specific tests, which may help sport scientists and strength and conditioning coaches to better tailor training programs and to optimize performance in elite hockey players.

AbstractLesion-symptom mapping is often employed to define brain structures that are crucial for human behavior. Even though poststroke deficits result from gray matter damage as well as secondary white matter loss, the impact of structural disconnection is overlooked by conventional lesion-symptom mapping because it does not measure loss of connectivity beyond the stroke lesion. This study describes how traditional lesion mapping can be combined with structural connectome lesion symptom mapping (CLSM) and connectome dynamics lesion symptom mapping (CDLSM) to relate residual white matter networks to behavior. Using data from a large cohort of stroke survivors with aphasia, we observed improved prediction of aphasia severity when traditional lesion symptom mapping was combined with CLSM and CDLSM. Moreover, only CLSM and CDLSM disclosed the importance of temporal-parietal junction connections in aphasia severity. In summary, connectome measures can uniquely reveal brain networks that are necessary for function, improving the traditional lesion symptom mapping approach.
Phosphoinositol-4,5-Bisphosphate Regulates Auditory Hair-Cell Mechanotransduction-Channel Pore Properties and Fast Adaptation
Authors: Effertz Thomas , Becker Lars , Peng Anthony W. , Ricci Anthony J. 
Published: October 2017

Membrane proteins, such as ion channels, interact dynamically with their lipid environment. Phosphoinositol-4,5-bisphosphate (PIP2) can directly or indirectly modify ion-channel properties. In auditory sensory hair cells of rats (Sprague Dawley) of either sex, PIP2localizes within stereocilia, near stereocilia tips. Modulating the amount of free PIP2in inner hair-cell stereocilia resulted in the following: (1) the loss of a fast component of mechanoelectric-transduction current adaptation, (2) an increase in the number of channels open at the hair bundle's resting position, (3) a reduction of single-channel conductance, (4) a change in ion selectivity, and (5) a reduction in calcium pore blocking effects. These changes occur without altering hair-bundle compliance or the number of functional stereocilia within a given hair bundle. Although the specific molecular mechanism for PIP2action remains to be uncovered, data support a hypothesis for PIP2directly regulating channel conformation to alter calcium permeation and single-channel conductance.SIGNIFICANCE STATEMENTHow forces are relayed to the auditory mechanoelectrical transduction (MET) channel remains unknown. However, researchers have surmised that lipids might be involved. Previous work on bullfrog hair cells showed an effect of phosphoinositol-4,5-bisphosphate (PIP2) depletion on MET current amplitude and adaptation, leading to the postulation of the existence of an underlying myosin-based adaptation mechanism. We find similar results in rat cochlea hair cells but extend these data to include single-channel analysis, hair-bundle mechanics, and channel-permeation properties. These additional data attribute PIP2effects to actions on MET-channel properties and not motor interactions. Further findings support PIP2's role in modulating a fast, myosin-independent, and Ca2+-independent adaptation process, validating fast adaptation's biological origin. Together this shows PIP2's pivotal role in auditory MET, likely as a direct channel modulator.
A Subconscious Interaction between Fixation and Anticipatory Pursuit
Authors: Watamaniuk Scott N.J. , Bal Japjot , Heinen Stephen J. 
Published: October 2017

Ocular smooth pursuit and fixation are typically viewed as separate systems, yet there is evidence that the brainstem fixation system inhibits pursuit. Here we present behavioral evidence that the fixation system modulates pursuit behavior outside of conscious awareness. Human observers (male and female) either pursued a small spot that translated across a screen, or fixated it as it remained stationary. As shown previously, pursuit trials potentiated the oculomotor system, producing anticipatory eye velocity on the next trial before the target moved that mimicked the stimulus-driven velocity. Randomly interleaving fixation trials reduced anticipatory pursuit, suggesting that a potentiated fixation system interacted with pursuit to suppress eye velocity in upcoming pursuit trials. The reduction was not due to passive decay of the potentiated pursuit signal because interleaving “blank” trials in which no target appeared did not reduce anticipatory pursuit. Interspersed short fixation trials reduced anticipation on long pursuit trials, suggesting that fixation potentiation was stronger than pursuit potentiation. Furthermore, adding more pursuit trials to a block did not restore anticipatory pursuit, suggesting that fixation potentiation was not overridden by certainty of an imminent pursuit trial but rather was immune to conscious intervention. To directly test whether cognition can override fixation suppression, we alternated pursuit and fixation trials to perfectly specify trial identity. Still, anticipatory pursuit did not rise above that observed with an equal number of random fixation trials. The results suggest that potentiated fixation circuitry interacts with pursuit circuitry at a subconscious level to inhibit pursuit.SIGNIFICANCE STATEMENTWhen an object moves, we view it with smooth pursuit eye movements. When an object is stationary, we view it with fixational eye movements. Pursuit and fixation are historically regarded as controlled by different neural circuitry, and alternating between invoking them is thought to be guided by a conscious decision. However, our results show that pursuit is actively suppressed by prior fixation of a stationary object. This suppression is involuntary, and cannot be avoided even if observers are certain that the object will move. The results suggest that the neural fixation circuitry is potentiated by engaging stationary objects, and interacts with pursuit outside of conscious awareness.

OBJECTIVES:To examine intelligence, language, and academic achievement through 18 years of age among children with congenital cytomegalovirus infection identified through hospital-based newborn screening who were asymptomatic at birth compared with uninfected infants.METHODS:We used growth curve modeling to analyze trends in IQ (full-scale, verbal, and nonverbal intelligence), receptive and expressive vocabulary, and academic achievement in math and reading. Separate models were fit for each outcome, modeling the change in overall scores with increasing age for patients with normal hearing (n = 78) or with sensorineural hearing loss (SNHL) diagnosed by 2 years of age (n = 11) and controls (n = 40).RESULTS:Patients with SNHL had full-scale intelligence and receptive vocabulary scores that were 7.0 and 13.1 points lower, respectively, compared with controls, but no significant differences were noted in these scores among patients with normal hearing and controls. No significant differences were noted in scores for verbal and nonverbal intelligence, expressive vocabulary, and academic achievement in math and reading among patients with normal hearing or with SNHL and controls.CONCLUSIONS:Infants with asymptomatic congenital cytomegalovirus infection identified through newborn screening with normal hearing by age 2 years do not appear to have differences in IQ, vocabulary or academic achievement scores during childhood, or adolescence compared with uninfected children.

Published: October 2017

Many scholars feel that due to the intensity of college sport, student-athletes are confined to borders, being denied a well-rounded experience (Potuto & O’Hanlon, 2007). Although past research has focused on the educational experiences in regards to the general student-athlete population, few studies have focused on the culture that constructs the overall student-athlete experience. This study utilized the narrative methodology, revealing the genuine human experience and assisting in mobilizing action for progressive social change (Riessman, 2008). This study utilized semi-structured interviews and journals to examine the embodied in-season experience of an athletically gifted Cuban FCS football student-athlete. Open coding revealed two major themes that will be discussed: football, identity, social support, and stereotype. This study is one of the first to explore the experience of a FCS student-athlete and sheds light on a Cuban football student-athlete’s experience.
The Occupational Socialization of Athletic Administrators: A Content Analysis of Graduate Program Websites
Authors: Comeaux Eddie 
Published: October 2017

Employing occupational socialization as an interpretive framework, this study drew on a content analysis of athletic administration graduate program websites to explore the relationship between the programs and key issues facing professionals in the field of intercollegiate athletics. Results revealed that the processes and mechanisms in place to prepare graduate students for careers in intercollegiate athletics appear to be adequate, but could more comprehensively address the increasingly complex business enterprise of college sports, NCAA policies and rules, and key strategies to develop the academic talents of athletes. Formal processes, such as courses and experiential learning activities (e.g., internships, practica, field research) in the studied graduate programs, appeared to dominate role learning; informal processes or unintentional learning, such as interactions with peers and other campus stakeholders, appeared to be absent. This study highlights new directions for future work aimed at understanding the professional preparation of athletic administrators.

Son muy escasas, por no decir inexistentes, las exposiciones en castellano del desarrollo histórico de la meteorología como saber milenario acerca de los procesos que tienen lugar „en lo alto“ (ta meteora). Ni siquiera se dispone de traducciones de las mejores sinopsis que se han escrito en otros idiomas. El padre de la historiografía de la meteorología, Gustav Hellmann, entre sus varias contribuciones imperecederas a la historia de la meteorología, publicó un ensayo en inglés, y luego en alemán, de cómo evolucionó el saber meteorológico en su fase precientífica. Ofrecemos al lector hispanohablante la traducción, con algunas notas, de ese ensayo clásico sobre el desarrollo de la meteorología, desde las épocas babilónicas hasta el comienzo de la Revolución Científica, cuando se crearon los medios instrumentales para cuantificar losprocesos atmosféricos. © 2017.

Aim of this study was to examine the characteristics cytology of mucous cell-,temperature- and pH vagina during estrous cycle in local sheep. 31local sheep were synchronized with vaginal sponge consist of 20 mg progesterone hormone before carried out observations of cytology of cells from the vaginal mucose through vaginal swabs, temperature and pH of the vagina. Vaginal swabs were collected daily at 7 am for a weeks.Vaginal temperature and pH measurement is carried out twice a day, at 07.00 am and 15.00 pm for a weeks after vaginal swabs. Smears of the swab were then prepared on glass slide and they were stained with Giemsa. Vaginal epithelial cells; Parabasal, intermediate and superficial cells were counted and their percentages during pro-estrous, estrous and di-estrous were determined. Di-estrous was characterized by the absent of superficial cells in the epithelial vagina. Pro-estrous was characterized by the increasing progressively of intermediate/superficial cells in epithelial vagina, whereas estrous was characterized by the presence of superficial/cornification cells in most epithelial vagina. Based on the dominance of superficial cell, the number of sheep identified as estrous is highest on third day, with 52%. Observation on vaginal temperature also resulting that the highest temperature values obtained on the third day of 39,08±0.28°C. It could be effected of the vaginal pH during the observation.

Published: October 2017

Case:
We report the successful use of arthroscopy for reduction and internal fixation of a posterior glenoid fracture in a 62-year-old man 5 days following a skiing accident. Additionally, we review the technique utilized for successful fixation of this rare fracture, and we report the postoperative return of function.

Conclusion:
Arthroscopically facilitated fixation of glenoid fractures has been reported in the literature with excellent clinical outcomes. However, arthroscopic reduction and screw fixation of a posterior intra-articular glenoid fracture (Ideberg type Ib), to our knowledge, has not been previously published. The unique benefits of arthroscopic screw fixation are discussed.
