Shoulder Strength and Range of Motion Between Collegiate Pitchers and Position Players in Baseball
International Journal of Exercise Science 13(6): 123-130, 2020. Baseball is a sport that places excessive strain on the shoulder complex caused from repetitive overhead throws. In the sport of baseball, shoulder strength and range of motion (ROM) are paramount for success on the field. The purpose of this study was to determine strength and ROM differences between collegiate baseball pitchers and position players. It was hypothesized that pitchers would have higher strength and ROM values, due to the volume of throwing a pitcher performs.A total of nine collegiate baseball pitchers and position players (n= 18) volunteered for the study (age = 20.94 ± 1.21 years, height = 183.42 ± 4.74 cm, and mass = 89.56 ± 10.76 kg). Shoulder strength was measured using a Humac Norm isokinetic dynamometer at 180ºsec-1 and 300ºsec-1and ROM was measured using a goniometer. All participants completed a five-minute warm-up at 50 rpm on an upper body ergometer. Following the warm-up, passive internal and external ROM were measured for the throwing (dominant) arm. No statistical differences were found in external ROM (p = 0.319), internal ROM (p= 0.258), external peak torque @180ºsec-1(p= 0.467), internal peak torque @180ºsec-1(p= 0.156), external peak torque @300ºsec-1(p= 0.225), or internal peak torque @300ºsec-1(p= 0.137). The findings indicate similar isokinetic strength and flexibility in the throwing shoulder of collegiate athletes who perform repeated overhead throwing motions. Thus, in this study the player’s baseball position (pitchers vs. position player) did not influence throwing shoulder strength and ROM characteristics
A concept for major incident triage: full-scaled simulation feasibility study
<p>Abstract</p> <p>Background</p> <p>Efficient management of major incidents involves triage, treatment and transport. In the absence of a standardised interdisciplinary major incident management approach, the Norwegian Air Ambulance Foundation developed Interdisciplinary Emergency Service Cooperation Course (TAS). The TAS-program was established in 1998 and by 2009, approximately 15 500 emergency service professionals have participated in one of more than 500 no-cost courses. The TAS-triage concept is based on the established triage Sieve and Paediatric Triage Tape models but modified with slap-wrap reflective triage tags and paediatric triage stretchers. We evaluated the feasibility and accuracy of the TAS-triage concept in full-scale simulated major incidents.</p> <p>Methods</p> <p>The learners participated in two standardised bus crash simulations: without and with competence of TAS-triage and access to TAS-triage equipment. The instructors calculated triage accuracy and measured time consumption while the learners participated in a self-reported before-after study. Each question was scored on a 7-point Likert scale with points labelled "Did not work" (1) through "Worked excellent" (7).</p> <p>Results</p> <p>Among the 93 (85%) participating emergency service professionals, 48% confirmed the existence of a major incident triage system in their service, whereas 27% had access to triage tags. The simulations without TAS-triage resulted in a mean over- and undertriage of 12%. When TAS-Triage was used, no mistriage was found. The average time from "scene secured to all patients triaged" was 22 minutes (range 15-32) without TAS-triage vs. 10 minutes (range 5-21) with TAS-triage. The participants replied to "How did interdisciplinary cooperation of triage work?" with mean 4,9 (95% CI 4,7-5,2) before the course vs. mean 5,8 (95% CI 5,6-6,0) after the course, p < 0,001.</p> <p>Conclusions</p> <p>Our modified triage Sieve tool is feasible, time-efficient and accurate in allocating priority during simulated bus accidents and may serve as a candidate for a future national standard for major incident triage.</p
Live Coding, Live Notation, Live Performance
This paper/demonstration explores relationships between code, notation including representation, visualisation and performance. Performative aspects of live coding activities are increasingly being investigated as the live coding movement continues to grow and develop. Although live instrumental performance is sometimes included as an accompaniment to live coding, it is often not a fully integrated part of the performance, relying on improvisation and/or basic indicative forms of notation with varying levels of sophistication and universality. Technologies are developing which enable the use of fully explicit music notations as well as more graphic ones, allowing more fully integrated systems of code in and as performance which can also include notations of arbitrary complexity. This itself allows the full skills of instrumental musicians to be utilised and synchronised in the process.
This presentation/demonstration presents work and performances already undertaken with these technologies, including technologies for body sensing and data acquisition in the translation of the movements of dancers and musicians into synchronously performable notation, integrated by live and prepared coding. The author together with clarinetist Ian Mitchell present a short live performance utilising these techniques, discuss methods for the dissemination and interpretation of live generated notations and investigate how they take advantage of instrumental musicians’ training-related neuroplasticity skills
Avaliação do Ensino de Empreendedorismo entre Estudantes Universitários por meio do Perfil Empreendedor
Entrepreneurship is a socioeconomic phenomenon that has been valued for its influence on the growth and
development of regional and national economies. The main promoter of this phenomenon are entrepreneurs,
subjects endowed with multiple features that make up their profiles. They are dynamic and results oriented,
benefitting from the fruits of their own personal efforts. Entrepreneurial education is highlighted as one of the most
efficient ways to promote an entrepreneurial culture and train new entrepreneurs. However, some difficulty has
been observed in assessing the effectiveness of teaching and learning this subject. The objective of this study was
to analyze, by means of multivariate techniques, an instrument whose function is to measure the learning of
Entrepreneurship, verifying the change in entrepreneur profiles of 407 college students participating or not in an
entrepreneurial training process. The results showed that students who participated in Entrepreneurship
educational training activities showed significant changes in their entrepreneurial profiles. The main contributions
showed growth in the Self-realization, Planner, Innovative and Risks Assumed dimensions
Improving Internal Peptide Dynamics in the Coarse-Grained MARTINI Model: Toward Large-Scale Simulations of Amyloid- and Elastin-like Peptides
We present an extension of the coarse-grained MARTINI
model for
proteins and apply this extension to amyloid- and elastin-like peptides.
Atomistic simulations of tetrapeptides, octapeptides, and longer peptides
in solution are used as a reference to parametrize a set of pseudodihedral
potentials that describe the internal flexibility of MARTINI peptides.
We assess the performance of the resulting model in reproducing various
structural properties computed from atomistic trajectories of peptides
in water. The addition of new dihedral angle potentials improves agreement
with the contact maps computed from atomistic simulations significantly.
We also address the question of which parameters derived from atomistic
trajectories are transferable between different lengths of peptides.
The modified coarse-grained model shows reasonable transferability
of parameters for the amyloid- and elastin-like peptides. In addition,
the improved coarse-grained model is also applied to investigate the
self-assembly of β-sheet forming peptides on the microsecond
time scale. The octapeptides SNNFGAIL and (GV)4 are used
to examine peptide aggregation in different environments, in water,
and at the water–octane interface. At the interface, peptide
adsorption occurs rapidly, and peptides spontaneously aggregate in
favor of stretched conformers resembling β-strands
Metarrestin, a perinucleolar compartment inhibitor, effectively suppresses metastasis
Metastasis remains a leading cause of cancer mortality due to the lack of specific inhibitors against this complex process. To identify compounds selectively targeting the metastatic state, we used the perinuclear compartment (PNC), a complex nuclear structure associated with metastatic behaviors of cancer cells, as a phenotypic marker for a high-content screen of over 140,000 structurally diverse compounds. Metarrestin, obtained through optimization of a screening hit, disassembles PNCs in multiple cancer cell lines, inhibits invasion in vitro, suppresses metastatic development in three mouse models of human cancer, and extends survival of mice in a metastatic pancreatic cancer xenograft model with no organ toxicity or discernable adverse effects. Metarrestin disrupts the nucleolar structure and inhibits RNA polymerase (Pol) I transcription, at least in part by interacting with the translation elongation factor eEF1A2. Thus, metarrestin represents a potential therapeutic approach for the treatment of metastatic cancer

Postcoital cyst rupture presenting as peritonitis and hemorrhagic shock: A case report
Introduction: This report presents an unusual case of severe post-coital abdominal pain and signs of hemorrhagic shock requiring admission to a surgical intensive care unit (SICU) and emergent laparoscopy. This case was unique given the timing and progression of the patient's symptoms, as well as her age, surgical history, and symptomatic progression. Here we document the notable characteristics and treatment of this patient. Case presentation: The patient presented to a local emergency department with signs progressive peritonitis and shock after an episode of non-traumatic intercourse. Her initial computed tomography (CT) scan showed signs of free fluid in the abdomen around the bladder and liver with no definitive source of bleed. She developed worsening shock with severe pain. She was then emergently transferred to a tertiary care center for evaluation by gynecology service and for general trauma surgery evaluation. She was further stabilized in the emergency department, and then admitted to the surgical critical care service. Following additional imaging, she received exploratory surgery with gynecology to control a hemorrhagic ruptured cyst. She remained stable and was discharged the next day. Conclusion: This case demonstrated a complication of an often-benign diagnosis, revealing the potential danger of underestimating this chief complaint, as well as the importance of understanding how minimal trauma can lead to cyst rupture. © 2022 The AuthorsOpen access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
