Microrollers flow uphill as granular media.

Pour sand into a container and only the grains near the top surface move. The collective motion associated with the translational and rotational energy of the grains in a thin flowing layer is quickly dissipated as friction through multibody interactions. Alternatively, consider what will happen to a bed of particles if one applies a torque to each individual particle.

Mastitis Control and Intramammary Antimicrobial Stewardship in Ireland: Challenges and Opportunities.

The Veterinary Medicines Regulation (EU 2019/6) came into force in all EU member states on 28 January 2022. This regulation places particular emphasis on prudent and responsible antimicrobial use in food animal production. Key changes include restrictions on the prophylactic use of antimicrobials in animals, and the possibility to reserve certain antimicrobials for humans only.

The Cl isotope composition and halogen contents of Apollo-return samples.

Lunar mare basalts are depleted in F and Cl by approximately an order of magnitude relative to mid-ocean ridge basalts and contain two Cl-bearing components with elevated isotopic compositions relative to the bulk-Earth value of ∼0‰. The first is a water-soluble chloride constituting 65 ± 10% of total Cl with δCl values averaging 3.0 ± 4.

Dynamic Leap and Balance Test: Ability to Discriminate Balance Deficits in Individuals With Chronic Ankle Instability.

Context: The Dynamic Leap Balance Test (DLBT) is a new dynamic balance task that requires serial changes in base of support with alternating limb support and recovery of dynamic stability, as compared with the Y modification of the Star Excursion Balance Test (Y-SEBT), which assesses dynamic stability over an unchanging base of support.

Objectives: To assess the dynamic balance performance in 2 different types of dynamic balance tasks, the DLBT and the SEBT, in subjects with unilateral chronic ankle instability (CAI) when compared with matched controls. The authors hypothesized that the DLBT score would significantly differ between the CAI involved and uninvolved limbs (contralateral and healthy matched) and demonstrate a modest (r = .

The Comparative Effects of Ankle Bracing on Functional Performance.

Ankle sprains represent a common musculoskeletal injury that clinicians are tasked with preventing and treating. Because of the prevalence of this injury, ankle braces have been designed to prophylactically protect the joint and reduce the incidence of repetitive sprains. Although an abundance of literature exists focusing on the efficacy of braces in preventing ankle sprains in young, healthy, and physically active populations, there is a scarcity of evidence specific to the impact of these apparatuses on functional performance; therefore, the purpose of this critically appraised topic (CAT) is to investigate the effects of ankle braces on functional performance measures in such individuals.

Prophylactic Ankle Bracing in Military Settings: A Review of the Literature.

Background: Within athletics and the military, ankle sprains are one of the most common injuries with the potential for long-term functional deficits. Incidence rates for ankle sprains within the military are one of the leading causes of limited duty days, especially during basic combat training, parachute training exercises, and in cadet populations. In 2008, the Department of Defense U.

Injury and illness epidemiology at a summer sport-camp program, 2008 through 2011.

Can the Communion of Saints Help the Search for Justice in Dying well (Enough), "In Abraham's Arms, Where Lazarus is Poor no Longer"?

How can we practice dying in community? What communal practices nourish positive acts that make dying well (enough)-more than prudent caution in avoiding causing death (killing)? What part of our common ecclesial life as Catholics enables us to accompany dying persons as a gracious return to God? We are twice haunted: most first world deaths result from foreseen end-stage illnesses; mortality is less feared than burdensomeness for caregivers from vulnerable dependence. Of those who die in the hospital, many deaths result from decisions to withhold and withdraw treatments. From ten kinds of desolation about dying, ten parallel consolations are discerned in hopes and outcomes-based best practices.

Injury/illness physician referral profile from a youth university-sponsored summer sport camp program.

Participation at university-sponsored summer sport camps is popular among youth athletes; however, there is a dearth of information to describe the injuries/illnesses experienced by camp participants. Data from a university-sponsored sport camp program from 2008 to 2011 were accessed retrospectively. The sport camp program had approximately 80 camps for 28 sports over 12 weeks annually.

Objective: To evaluate the safety and efficacy of alcaftadine for the prevention of itching associated with allergic conjunctivitis.

Data Sources: A medical literature search was conducted in MEDLINE/PubMed (2006-February 2012) and EMBASE (2006-February 2012) using the search terms alcaftadine and Lastacaft. References from these publications were reviewed for additional resources.

Gold sodium thiomalate for the treatment of rheumatoid arthritis in a patient with hepatitis B.

Objective: To describe a case of gold sodium thiomalate use for the treatment of rheumatoid arthritis (RA) in a patient with hepatitis B.

Case Summary: A 53-year-old Korean American woman with mild RA and chronic hepatitis B infection was treated for worsening RA symptoms with subcutaneous injections of gold sodium thiomalate for 21 months, with the dosage decreased from the initial 40 mg per week to 40 mg every 3 weeks after 51 weeks of successful treatment. She had undergone treatment for hepatitis B in the past with lamivudine; however, she had not received that medication for at least 1 year prior to initiating treatment with gold sodium thiomalate injections.

Root cadmium desorption methods and their evaluation with compartmental modeling.

• Desorption of plant roots is often employed in studies of plant physiology and nutrition; however, there have been few studies on the validity of desorption procedures. • Branched and in-line kinetic models with five compartments - cadmium (Cd)-chelate, Cd(2+), root apoplast, root symplast and vacuole - were developed to evaluate the efficacy of diethylenetriaminepentaacetic acid (DTPA) and CaCl(2) methods for the desorption of Cd from roots of durum wheat seedlings. Solution Cd(2+) could exchange with apoplast and symplast Cd simultaneously in the branched model and sequentially in the in-line model.

Premature knee osteoarthritis after anterior cruciate ligament reconstruction dependent on autograft.

Anterior cruciate ligament (ACL) reconstructions are common postoperative orthopedic conditions encountered by sports rehabilitation specialists. The rationale for reconstructing the ACL is to restore mechanical stability of the knee joint and prevent associated musculoskeletal sequelae. The selection of available autogenous graft options for surgical interventions continues to be a controversial topic in orthopedic sports medicine.

Systematic review of efficacy for manual lymphatic drainage techniques in sports medicine and rehabilitation: an evidence-based practice approach.

Manual therapists question integrating manual lymphatic drainage techniques (MLDTs) into conventional treatments for athletic injuries due to the scarcity of literature concerning musculoskeletal applications and established orthopaedic clinical practice guidelines. The purpose of this systematic review is to provide manual therapy clinicians with pertinent information regarding progression of MLDTs as well as to critique the evidence for efficacy of this method in sports medicine. We surveyed English-language publications from 1998 to 2008 by searching PubMed, PEDro, CINAHL, the Cochrane Library, and SPORTDiscus databases using the terms lymphatic system, lymph drainage, lymphatic therapy, manual lymph drainage, and lymphatic pump techniques.

Analytical variables affecting exchangeable copper determination in blood plasma.

To resolve discrepancies observed in the determination of plasma exchangeable Cu (also called direct reacting Cu or loosely bound Cu) by several methods, plasma storage techniques and various aspects of a stable isotope dilution procedure for exchangeable Cu were evaluated. Results indicated that the exchangeable Cu fraction of plasma increased with storage at room temperature, at 5 degrees C and when subjected to repeated freeze/thaw cycles. Samples could be safely stored at -65 degrees C.

Factors associated with anterior cruciate ligament injury: history in female athletes.

Aim: Little is known about the association of lower extremity structural malalignments, flexibility patterns, generalized laxity, postural control, previous ankle sprain history and the increased risk of anterior cruciate ligament (ACL) injuries in females. We hypothesized that females with a history of ACL injury would be more likely to have a history of prior ankle sprain and different structural alignments than females without a history of ACL injury.

Methods: It is a case control study: 33 young adult females with a history of an ACL injury and 33 controls with no history of knee injury provided their knee and ankle injury history and had 16 lower extremity measures taken.

The Effects of Fatigue and Chronic Ankle Instability on Dynamic Postural Control.

OBJECTIVE: Deficits in static postural control related to chronic ankle instability (CAI) and fatigue have been investigated separately, but little evidence links these factors to performance of dynamic postural control. Our purpose was to investigate the effects of fatigue and CAI on performance measures of a dynamic postural-control task, the Star Excursion Balance Test. DESIGN AND SETTING: For each of the 3 designated reaching directions, 4 separate 5 (condition) x 2 (time) x 2 (side) analyses of variance with a between factor of group (CAI, healthy) were calculated for normalized reach distance and maximal ankle-dorsiflexion, knee-flexion, and hip-flexion angles.
