PURPOSE: This study compares the use of a standard 7 mm resection length to a variable 4:1 ratio of resection length to desired elevation nomogram when performing Muller's muscle conjunctival resection surgery. METHODS: In this cross-sectional case control study, 2 groups were defined. The first underwent Muller's muscle conjunctival resection surgery with a standard 7 mm resection length and the second underwent the same surgery with a variable resection length determined by a 4:1 ratio of resection length to desired elevation nomogram...

Obstructive lung diseases are common causes of disability and death worldwide. A hallmark feature is aberrant activation of Gq protein-dependent signaling cascades. Currently, drugs targeting single G protein (heterotrimeric guanine nucleotide-binding protein)-coupled receptors (GPCRs) are used to reduce airway tone. However, therapeutic efficacy is often limited, because various GPCRs contribute to bronchoconstriction, and chronic exposure to receptor-activating medications results in desensitization. We therefore hypothesized that pharmacological Gq inhibition could serve as a central mechanism to achieve efficient therapeutic bronchorelaxation...

Stable isotope ratios ((13)C/(12)C and (15)N/(14)N) of South African lambs from different regions were measured by isotope ratio mass spectrometry (IRMS). Homogenised and defatted meat of the Longissimus lumborum muscle was assessed. The Rûens and Hantam Karoo regions had the lowest (P≤0.05) δ(13)C values related to the presence of C3 plants (lucerne and Karoo bushes, respectively). The Northern Karoo, Namibia and Bushmanland had the highest δ(13)C values likely due to a high proportion of dietary C4 grass species...

The authors innovated the levator aponeurosis and Muller muscle plication reinforced with levator sheath advancement (AMPSA) for blepharoptosis correction. The orbital septum was opened 1 mm above its fusion with the levator aponeurosis. The preaponeurotic fat was retracted and the thickened part of the levator sheath was identified. Two plication sutures were made: medial suture at the medial border of the pupil and lateral between the lateral border of the pupil and the lateral limbus. A needle with 6-0 nylon thread first bit the tarsal plate approximately 1 mm below its upper border, then bit the levator aponeurosis and the Muller muscle together at 3 to 6 mm above the upper border of the tarsal plate...

The secreted growth factor Activin-A of the TGFβ family and its receptors can promote or inhibit several cancer hallmarks including tumor cell proliferation and differentiation, vascularization, lymphangiogenesis and inflammation. However, a role in immune evasion and its relationship with tumor-induced muscle wasting and tumor vascularization, and the relative contributions of autocrine versus paracrine Activin signaling remain to be evaluated. To address this, we compared the effects of truncated soluble Activin receptor II B as a ligand trap, or constitutively active mutant type IB receptor versus secreted Activin-A or the related ligand Nodal in mouse and human melanoma cell lines and tumor grafts...

BACKGROUND: Transcranial direct current stimulation (tDCS) can polarize the cortex of the human brain. OBJECTIVE/HYPOTHESIS: We sought to verify the hypothesis that posterior-anterior (PA) but not anterior-posterior (AP) tDCS of primary motor cortex (M1) produces cooperative effects with corticospinal plasticity induced by paired associative stimulation of the supplementary motor area (SMA) to M1 projection (PASSMA→M1) in a highly controlled experimental design...

The purpose of this study was to investigate blood pressure (BP) and leg skeletal muscle oxygen saturation (SmO2) during treadmill walking in patients with peripheral artery disease (PAD) and healthy subjects. Eight PAD patients (66 ± 3 years, 1 female) and eight healthy subjects (65 ± 2 years, 1 female) walked on a treadmill at 2 miles/hour. The incline increased by 2% every 2 minutes from 0% to 15% or until maximal discomfort. BP was measured every 2 min with an auscultatory cuff. Heart rate (HR) was recorded continuously with an electrocardiogram...

Body machine interfaces (BMIs) are used by people with severe motor disabilities to control external devices, but they also offer the opportunity to focus on rehabilitative goals. In this study we introduced in a clinical setting a BMI that was integrated by the therapists in the rehabilitative treatments of 2 spinal cord injured (SCI) subjects for 5 weeks. The BMI mapped the user's residual upper body mobility onto the two coordinates of a cursor on a screen. By controlling the cursor, the user engaged in playing computer games...

Heat shock proteins (HSPs) are endogenous proteins whose function is to maintain the cell's tolerance to insult, and glutamine supplementation is known to increase HSP expression during intense exercise. Since few studies have addressed the possibility that supplementation with other amino acids could have similar effects to that of glutamine, our objective was to evaluate the effects of leucine, valine, isoleucine and arginine as potential stimulators of HSPs 25, 60, 70 and 90 in rats subjected to acute exercise as a stressing factor...

BACKGROUND: Previously published data indicate that BMP-2 gene activated muscle tissue grafts can repair large bone defects in rats. This innovative abbreviated ex vivo gene therapy is appealing since it does not require elaborative and time-consuming extraction and expansion of cells. Hence, in the here presented experimental study we evaluated the potential of this expedited tissue engineering approach to regenerate osteochondral defects in rabbits. METHODS: Autologous muscle tissue grafts from female White New Zealand rabbits were directly transduced with an adenoviral BMP-2 vector or remained unmodified...

Subarachnoid hemorrhage (SAH) is a serious clinical condition where leakage of blood into the subarachnoid space causes an acute rise in intracranial pressure and reduces cerebral blood flow, which may lead to delayed cerebral ischemia and poor outcome. In experimental SAH, we have previously shown that the outcome can be significantly improved by early inhibition of the MAPK/ERK kinase/extracellular signal-regulated kinase (MEK/ERK1/2) pathway. The aim of this study was to apply mass spectrometry to investigate the overall late effects of experimental SAH on cerebrovascular protein expression...

Core muscle imbalances and weak trunk strength are relevant for injury prevention and performance. Information regarding core strength requirements and ideal flexion/extension ratios in alpine skiing is limited. We aimed to compare trunk strength capacities in elite alpine skiers with those of a matched control group. The concentric maximal trunk flexion and extension of 109 elite skiers and 47 active controls were measured at 150°/s in a ballistic mode using the CON-TREX® TP 1000 test system. The relative flexion peak torque was higher in male ski racers (p = 0...

OBJECTIVE: Many patients with congenital heart disease (CHD) require surgery to ensure survival into adulthood. But history of previous thoracotomies is associated with respiratory muscle weakness, impairments in chest wall compliance, and moderately to severely impaired lung function. This study evaluated the impact of thoracotomies on functional outcome in patients with CHD. PATIENTS AND METHODS: In total 1372 adolescents and adults with CHD (32.4±11.5 years, 624 female), who underwent spirometry and cardiopulmonary exercise testing in our institution from January 2010 to August 2015, were analyzed...

Whereas static vocal fold medialization or lateralization are currently the standard procedures, new dynamic treatment methods such as reinnervation and laryngeal pacing focus on better toning and remobilization of the paralyzed vocal folds. End-to-end or jump anastomoses of the recurrent laryngeal nerve can preserve muscle mass and avoid atrophy, thus enabling subsequent dynamic therapeutic options. Prognostic evaluation and the time point of therapeutic intervention are important issues in the management of patients with recurrent laryngeal nerve paralysis...

Bothropic venom contains a range of biologically active substances capable of causing severe local and systemic envenoming symptomatology within its victims. The snake anti-venom is effective against systemic effects but has no neutralizing effect against the fast developing local effects. Herein, mice gastrocnemius injected with Bothrops moojeni venom (40 μg/kg) or saline solution were irradiated with HeNe (632.8 nm) and GaAs (904 nm) lasers (daily energy density of 4 J/cm(2); 0.03/0.21 power density; 0...

Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is a congenital disorder characterized by loss of smooth muscle contraction in the bladder and intestine. To date, three genes are known to be involved in MMIHS pathogenesis: ACTG2, MYH11, and LMOD1. However, for approximately 10% of affected individuals, the genetic cause of the disease is unknown, suggesting that other loci are most likely involved. Here, we report on three MMIHS-affected subjects from two consanguineous families with no variants in the known MMIHS-associated genes...

INTRODUCTION: When performing total hip arthroplasty (THA), it is important to maintain the femoral and acetabular offsets to ensure good joint stability and to restore the function of the hip abductor muscles. In our practice, we mainly use a lateralized stem and hollow out the acetabulum to the quadrilateral plate to accommodate a press-fit polyethylene cup. However, the repercussions of this preparation method, which is driven by the cup's design, are not known. We carried out a retrospective study to assess: (1) the changes in the femoral and acetabular offset; (2) the height of the center of rotation; and (3) the repercussions on wear...

We report on a 32-year-old male patient with acute left-hemispheric stroke caused by embolism due to infective endocarditis affected from the HACEK group. Additionally, atypical findings from the transesophageal echocardiography (TEE) which showed fluttering structures belonging to the papillary muscle could be proven as infectious agents with the help of a glucose positron emission tomography (PET) scan. TEE controls showed increasing vegetation involving the mitral valve so that surgery became necessary. The current work reflects, in detail, the emergent clinical course of this young patient, suffering from both an unusual localization and an infrequent cause of endocarditis and focuses on an actual view to the literature...

Mutations of the human valosin-containing protein, p97 (VCP) and Wiskott-Aldrich syndrome protein and SCAR homolog (WASH) complex genes cause motor neuron and cognitive impairment disorders. Here, we analyzed a cohort of German patients with sporadic amyotrophic lateral sclerosis and frontotemporal lobar degeneration comorbidity (ALS/FTD) for VCP and WASH complex gene mutations. Next-generation panel sequencing of VCP, WASH1, FAM21C, CCDC53, SWIP, strumpellin, F-actin capping protein of muscle Z-line alfa 1 (CAPZA1), and CAPZB genes was performed in 43 sporadic ALS/FTD patients...
