Arie J van Duijn, Shawn D Felton
The patient was an 18-year-old collegiate baseball pitcher who injured his right throwing elbow during an overhead slider pitch. As a part of a study, preinjury ultrasound images of the throwing arm were obtained 2 weeks prior to the injury. One day postinjury, repeat ultrasound imaging of the medial elbow was performed. The attending team physician ordered a magnetic resonance arthrogram 2 days after injury, which confirmed the presence of a complete tear of the ulnar collateral ligament.

PURPOSE: Scapular dyskinesis is a recognized cause of shoulder pain in the throwing shoulder of baseball pitchers and athletes who participate in overhead sports. Past studies have assessed scapular kinematics using electromagnetic tracking devices and have shown a correlation between posterior shoulder tightness and forward scapular posture. The purpose of our study is to evaluate the scapular kinematics, before and after a 4-week posterior stretching protocol in asymptomatic pitchers...

BACKGROUND: Ulnar collateral ligament reconstruction (UCLR) has become a common procedure performed in overhead-throwing athletes of many athletic levels. PURPOSE/HYPOTHESIS: The purpose of this study was to determine whether clinical outcomes and return-to-sport (RTS) rates differ among patients undergoing UCLR based on graft choice, surgical technique, athletic competition level, handedness, and treatment of the ulnar nerve. We hypothesized that no differences would exist in clinical outcomes or RTS rates between technique, graft choice, or other variables...

In humans, reward cues, including drug cues in addicts, are especially effective in biasing attention towards them, so much so they can disrupt ongoing task performance. It is not known, however, whether this happens in rats. To address this question, we developed a behavioral paradigm to assess the capacity of an auditory drug (cocaine) cue to evoke cocaine-seeking behavior, thus distracting thirsty rats from performing a well-learned sustained attention task (SAT) to obtain a water reward. First, it was determined that an auditory cocaine cue (tone-CS) reinstated drug-seeking equally in sign-trackers (STs) and goal-trackers (GTs), which otherwise vary in the propensity to attribute incentive salience to a localizable drug cue...

David W Armitage
Bacteria are hypothesized to provide a variety of beneficial functions to plants. Many carnivorous pitcher plants, for example, rely on bacteria for digestion of captured prey. This bacterial community may also be responsible for the low surface tensions commonly observed in pitcher plant digestive fluids, which might facilitate prey capture. I tested this hypothesis by comparing the physical properties of natural pitcher fluid from the pitcher plant Darlingtonia californica and cultured 'artificial' pitcher fluids and tested these fluids' prey retention capabilities...

J A Lewis, T E Pitcher
This study examined whether polyandrous female Chinook salmon Oncorhynchus tshawytscha obtain benefits compared with monandrous females through an increase in hatching success. Both of the alternative reproductive tactics present in male O. tshawytscha (large hooknoses and small, precocious jacks) were used, such that eggs were either fertilized by a single male (from each tactic) or multiple males (using two males from the same or different tactics). The results show that fertilized eggs from the polyandrous treatments had a significantly higher hatching success than those from the monandrous treatments...

BACKGROUND: Weighted-ball throwing programs are commonly used in training baseball pitchers to increase ball velocity. The purpose of this study was to compare kinematics and kinetics among weighted-ball exercises with values from standard pitching (ie, pitching standard 5-oz baseballs from a mound). HYPOTHESIS: Ball and arm velocities would be greater with lighter balls and joint kinetics would be greater with heavier balls. STUDY DESIGN: Controlled laboratory study...

BACKGROUND: Pitching biomechanical analysis has been recommended as an important component of performance, injury prevention, and rehabilitation. Normal values for youth pitching stride length have not been established, leading to application of normative values found among professional pitchers to youth pitchers. HYPOTHESES: The average youth pitching stride length will be significantly less than that of college and professional pitchers. There will be a positive correlation between stride length, lower extremity power, balance, and pitching experience...

Aluminum is a neurotoxic metal with known health effects in animals and humans. Glutathione-S-transferase (GST) genes and enzymes play a major role in detoxification of several heavy metals. Besides a direct relationship with oxidative stress; aluminum decreases GST enzyme activities. Using data from 116 Jamaican children; age 2-8 years; with Autism Spectrum Disorder (ASD) and 116 sex- and age-matched typically developing (TD) children; we investigated the association of polymorphisms in three GST genes (GSTP1; GSTM1; and GSTT1) with mean blood aluminum concentrations in children with and without ASD...

Rob Gray, Anders Orn, Tim Woodman
Are pressure-induced performance errors in experts associated with novice-like skill execution (as predicted by reinvestment/conscious processing theories) or expert execution towards a result that the performer typically intends to avoid (as predicted by ironic processes theory)? The present study directly compared these predictions using a baseball pitching task with two groups of experienced pitchers. One group was shown only their target while the other was shown the target and an ironic (avoid) zone. Both groups demonstrated significantly fewer target hits under pressure...

To gain deeper insight into respective contributions of perceptual and motor experience of an observed action to anticipating its result, we examined the perceptual anticipation of players with different action roles in striking sports. Baseball pitchers and batters at both advanced and intermediate levels were asked to make a decision about whether to swing the bat when viewing a series of videos showing incomplete sequences of a model pitcher throwing a strike or a ball. The results revealed that first 100 ms of ball flight could discriminate advanced batters from intermediate pitchers and batters (with no difference between intermediate pitchers and batters)...

Rett Syndrome (RTT) is a neurodevelopmental disorder characterized by loss of acquired skills during development, autonomic dysfunction, and an increased risk for premature lethality. Clinical experience identified a subset of individuals with RTT that present with urological dysfunction including individuals with frequent urinary tract infections, kidney stones, and urine retention requiring frequent catheterization for bladder voiding. To determine if urologic dysfunction is a feature of RTT, we queried the Rett Syndrome Natural History Study, a repository of clinical data from over 1000 individuals with RTT and found multiple instances of urological dysfunction...

We describe an unusual case of acute ulnar neuropathy with a flexible claw hand deformity in a baseball pitcher. Treatment involved ulnar nerve decompression at the elbow with subsequent recurrence of symptoms upon return to pitching. Definitive treatment included a wide secondary release of tethered locations resulting in return of function. At final follow-up the patient has returned to unrestricted baseball throwing activities.

REVIEW
Marie Monniaux, Angela Hay
A key question in biology is how the endless diversity of forms found in nature evolved. Understanding the cellular basis of this diversity has been aided by advances in non-model experimental systems, quantitative image analysis tools, and modeling approaches. Recent work in plants highlights the importance of cell wall and cuticle modifications for the emergence of diverse forms and functions. For example, explosive seed dispersal in Cardamine hirsuta depends on the asymmetric localization of lignified cell wall thickenings in the fruit valve...

Baseball players are most likely to incur an anterior cruciate ligament injury while fielding or base running. Infielders and outfielders are most at risk, followed by pitchers. Return to play at the preinjury level after anterior cruciate ligament reconstruction is highly likely for these athletes.

Aldehyde dehydrogenase typically perform oxidation of aldehydes to their corresponding carboxylic acid while reducing NAD(P)+ to NAD(P)H via covalent catalysis mediated by an active-site cysteine residue. One member of this superfamily, the enzyme 2-aminomuconate-6-semialdehyde dehydrogenase (AMSDH), is a component of the kynurenine pathway which catabolizes tryptophan in mammals and certain bacteria. AMSDH catalyzes the NAD+-dependent oxidation of 2-aminomuconate semialdehyde to 2-aminomuconate. We recently determined the first crystal structure of AMSDH and several catalytic cycle intermediates...

BACKGROUND: A glenohumeral internal rotation (IR) deficit or a total rotational motion (IR plus external rotation [ER]) deficit in the throwing shoulder compared with the nonthrowing shoulder has been shown to increase the risk of shoulder and elbow injuries. After a pitching session, both IR and total rotational motion deficits have been shown to occur naturally for an extended period of time in asymptomatic pitchers, but it is unclear how to best control these deficits between pitching sessions...

The physiological and haemodynamic changes that occur in pregnancy and the postpartum period increase the risk of aortic dissection. Loeys-Dietz syndrome results from mutations in the genes encoding components of the TGF-β signalling pathway; aortic pathology is of particular concern in this condition but other vascular abnormalities can also be present. Significant maternal morbidity and mortality has been described in patients with Loeys-Dietz syndrome, but successful and uncomplicated pregnancies are still possible...

PURPOSE: Serious arm injuries in youth baseball players have been increasing. Though a breakage in the kinetic chain could affect arm injuries, an association between arm injuries and insufficient support of the trunk and lower extremities is not well understood. The purpose of this study was to investigate the association of low back and knee pain with elbow and/or shoulder complaints among youth baseball players. METHODS: A self-administered questionnaire and document informed consent were mailed to youth athletes belonging to the Miyagi Amateur Sports Association...
