Controversy exists in the literature regarding antagonist activity of trunk muscles during different types of trunk loading, and the direction-specificity of activation of trunk muscles, particularly the deeper trunk muscles. This study aimed to systematically compare activation of a range of trunk muscles between directions of statically applied loads, and to consider the impact of breathing in this activation. In a semi-seated position, 13 healthy male participants resisted moderate inertial loads applied to the trunk in eight different directions...

International Federations in Paralympic sport should develop evidence based classification, based on the relative strength of association between impairment and activities that determine sport specific performance. The purpose of the current study was to assess the relationship between trunk strength impairment and three activities that determine performance in Wheelchair Rugby, and to determine whether this relationship supports the concept of "natural classes". Trunk muscle strength and three determinants of performance were assessed in 27 athletes The correlations between lateral trunk muscle strength and the determinant tilting the chair, and between forward trunk muscle strength and the determinants 1 m acceleration and sprint momentum were calculated...

We present the case of a 38-year-old man undergoing surgical repair of his pectoralis major tendon. An interscalene catheter was placed between the middle and lower trunks of the brachial plexus. Postoperatively, ropivacaine 0.2% was infused through postoperative day. The patient had excellent pain control requiring minimal opioid analgesics. A catheter between the middle and lower trunks of the brachial plexus provided excellent postoperative analgesia after pectoralis major tendon reinsertion. Additionally, the block likely protected the surgical repair during emergence from anesthesia and in the early postoperative period by providing a motor block of the pectoralis major muscle...

Biomagnetic monitoring of atmospheric pollution is a growing application in the field of environmental magnetism. Particulate matter (PM) in atmospheric pollution contains readily-measurable concentrations of magnetic minerals. Biological surfaces, exposed to atmospheric pollution, accumulate magnetic particles over time, providing a record of location-specific, time-integrated air quality information. This review summarizes current knowledge of biological material ('sensors') used for biomagnetic monitoring purposes...

Prurigo pigmentosa is a rare inflammatory skin disease of unknown origin, mostly described in the ethnic Japanese population. Etiology and pathogenesis are not completely known. Tetracyclines or dapsone are the therapy of choice. A 17-year-old Swiss patient with Turkish parents presented with pruritic rash on the neck and trunk, which started after a diet. Under therapy with doxycycline over 5 weeks, complete healing with slight reticular hyperpigmentation was observed.

Percutaneous coronary intervention is commonly used to treat coronary artery disease. Both transradial and transfemoral approaches are applied. In general, fewer complications are seen with the transradial approach compared to the transfemoral access, for which reason the transradial catheterization is frequently preferred. In this case presentation, we describe 2 cases of elective transradial coronary angiography both resulting in severe central vascular complications: perforation of the right subclavian artery with a mediastinal hematoma and dissection of the brachio-cephalic trunk and the aortic arch...

INTRODUCTION: Reaching movements in stroke patients are characterized by decreased amplitudes at the shoulder and elbow joints and greater displacements of the trunk, compared to healthy subjects. The importance of an appropriate and specific contraction of the interscapular and upper limb (UL) muscles is crucial to achieving proper reaching movements. Functional electrical stimulation (FES) is used to activate the paretic muscles using short-duration electrical pulses. OBJECTIVE: To evaluate whether the application of FES in the UL and interscapular muscles of stroke patients with motor impairments of the UL modifies patients' reaching patterns, measured using instrumental movement analysis systems...

BACKGROUND: Recent studies have demonstrated that surgical ventricular septal defect closure in childhood is associated with reduced functional capacity and disruption of the right ventricular force-frequency relationship during exercise. To further describe long-term cardiac function, we performed a non-invasive assessment of cardiac index during exercise in adults having undergone surgery for ventricular septal defect in early childhood. METHODS: A total of 20 patients (surgical age 2...

Paraspinous myopathy is a rare neuromuscular disorder characterized by selective involvement of the cervical, thoracic, or lumbar muscles. Leading clinical features include a bent spine or dropped head (antecollis). In myasthenia gravis (MG), patients may have camptocormia secondary to neuromuscular junction dysfunction of the paraspinal muscles, and this condition usually responds to acetylcholinesterase inhibitors or immunosuppressive treatments. However, concomitant MG and paraspinous myopathy with histologic and electrophysiologic evidence of myopathic changes of the paraspinal muscles has only been reported twice in the literature...

We show that regenerating planarians' normal anterior-posterior pattern can be permanently rewritten by a brief perturbation of endogenous bioelectrical networks. Temporary modulation of regenerative bioelectric dynamics in amputated trunk fragments of planaria stochastically results in a constant ratio of regenerates with two heads to regenerates with normal morphology. Remarkably, this is shown to be due not to partial penetrance of treatment, but a profound yet hidden alteration to the animals' patterning circuitry...

CO2 efflux (ECO2) from stems and branches is highly variable within trees. To investigate the mechanisms underlying the temporal dynamics and vertical variations in ECO2, we measured the stem ECO2 by infrared gas analysis (IRGA) and meteorological conditions at 10 different heights from 0.1 to 3.7 m aboveground on two consecutive days every month for 1 year in six Styphnolobium japonicum trees with a similar size. The results indicated that the seasonal change in ECO2 roughly followed the seasonal variations in woody tissue temperature (TW) and stem radial diameter increment (Di)...

Multiple mononeuropathy (MM) occurs rarely during systemic lupus erythematosus (SLE) but may lead to major disability. The aim of this study was to investigate the clinic-pathological presentations of MM during SLE, as well as long-term outcomes. We conducted a multicentric retrospective study that included patients receiving a diagnosis of MM during SLE. Ten patients were included (8 women and 2 men, median age at MM diagnosis: 40.4 years). SLE was diagnosed before MM in 9/10 patients (median time 8.2 years)...
