BACKGROUND: Non-penetrating mesh fixation is becoming widely accepted even though little is known about the short-term fixation strength of these techniques. Although clinical outcomes are the ultimate measure of effectiveness, ex vivo biomechanical evaluation provides insights about the load-carrying capacity of the mesh-tissue complex in vivo. As such, the purpose of this study was to compare the short-term fixation strength of three unique non-penetrating methods of fixation: LifeMesh™, ProGrip™, and Tisseel™...

BACKGROUND: The use of prophylactic mesh to prevent incisional hernia is becoming increasingly common in midline laparotomies and colostomies. The incidence of incisional hernia after subcostal laparotomies is lower than after midline incisions. Nevertheless, the treatment of subcostal incisional hernia is considered to be more complex. Currently, there are no published data about mesh augmentation procedures to close these laparotomies. METHODS: This was a longitudinal, prospective, cohort study of patients undergoing a bilateral subcostal laparotomy in elective operations...

BACKGROUND: There is an increasing interest in patient-reported outcome measurement to evaluate hernia operations. Several hernia-specific quality of life (QoL) scales have been proposed, but none are constructed for preoperative assessment. METHODS: The European Registry for Abdominal Wall Hernias (EuraHS) proposed the short, 9-question EuraHS-QoL instrument for assessment pre- and postoperatively. The EuraHS-QoL was evaluated in a prospective, multicenter validation study alongside the Visual Analogue Scale, Verbal Rating Scale, and Carolina Comfort Scale (https://clinicaltrials...

INTRODUCTION: Inguinal hernia repair is one of the most frequently performed surgical procedures worldwide in general surgery. The transabdominal laparoscopic (TAPP) approach in the therapy of inguinal hernia seems to be a suitable alternative to classical open inguinal hernia repair mainly in the hands of an experienced surgeon. TAPP repair offers the possibility of gentle dissection with implantation of the mesh and the possibility of non-invasive fixation of the implanted mesh. MATERIALS AND METHODS: Data analysis encompassed all patients who underwent inguinal hernia surgery at our Surgical Department within the period from July 1, 2012 to September 30, 2014 and who fulfilled the inclusion criteria...

INTRODUCTION: There are a group of patients in which umbilical or epigastric hernias co-exist with rectus divarication. These patients have weak abdominal musculature and are likely to pose a higher risk of recurrence following umbilical hernia repair. We would like to describe a technique for open repair of small (<4 cm) midline hernias in patients with co-existing rectus divarication using self-adhesive synthetic mesh. The use of a self-adhesive mesh avoids the need for suture fixation of the mesh in the superior portion of the abdomen, allowing for a smaller skin incision...

INTRODUCTION: This report describes for the first time a case of a transsacral rectocele after combined abdominotranssacral tumour resection. Furthermore, we demonstrate a method for laparoscopic defect repair. PRESENTATION OF CASE: A 44-year-old Caucasian female presented to our hospital with strange gurgling sounds and a painless subdermal swelling in her lower back after resection of a presacral neurinoma two years earlier. Magnetic resonance imaging (MRI) showed a huge rectocele through a sacral defect extending into the subcutaneous tissue...

INTRODUCTION: The role of fixation of the mesh is especially important in the endoscopic technique. The fixation of mesh through penetrating techniques using staples, clips or screws is associated with a significantly increased risk of developing a post-herniotomy pain syndrome. AIM: To demonstrate the safety and efficacy of the self-fixating anatomical Parietex ProGrip laparoscopic mesh (Sofradim Production, Trévoux France) used with laparoscopic transabdominal preperitoneal hernia repair...

How does the visual system differentiate self-generated motion from motion in the external world? Humans can discern object motion from identical retinal image displacements induced by eye movements, but the brain mechanisms underlying this ability are unknown. Here we exploit the frequent production of microsaccades during ocular fixation in the primate to compare primary visual cortical responses to self-generated motion (real microsaccades) versus motion in the external world (object motion mimicking microsaccades)...

Previously, we found that the amelioration of photosynthetic capacity by bottle gourd (Lagenaria siceraria Standl.) rootstock in watermelon seedlings (Citrullus lanatus [Thunb.] Mansf.) with salt treatment might be closely related to the enzymes in Calvin cycle such as ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) (Yang et al., 2012). We confirmed this and showed more details in this study that improved photosynthesis of watermelon plants by bottle gourd rootstock was associated with the decreased stomata resistance and the increased photochemical activity and photosynthetic metabolism with or without 100mM NaCl stress for 3 days...

UNLABELLED: BACGROUND/AIM. Intertrochanteric fractures of the femur are the third most common fractures among all bone fractures. Today in everyday orthopedic practice a number of different methods of treatment of trochanteric fractures of the femur are applied. Despite the improvement in the development of new implants, the percentage of serious complications of the treatment of these fractures remains very high, varying from 10% to 20%. One of the most serious complications of internal fixation of intertrochanteric fractures is nonunion of fractures due to the lack of additional axial dynamisation of implants...

We studied nine populations of a meadow mixed-mating plant Lychnis flos-cuculi growing in a gradient of copper smelter emissions. We hypothesize that metal tolerant populations in the polluted areas have experienced a loss of genetic variation and are more selfing than the populations from the unpolluted areas. One hundred and thirty-five parental plants and 1059 offspring were genotyped with six microsatellite markers. Selfing rates were assessed manually, with Rmes, Mltr and Colony2. Soil toxicity, population density and pollinators' activity were estimated in the studied areas...

Little is known about the relationship between attention allocation and dishonesty. The goal of the present work was to address this issue using the eyetracking methodology. We developed a novel task in which participants could honestly report seeing a particular card and lose money, or they could falsely report not seeing the card and not lose money. When participants cheated, they allocated less attention (i.e., shorter fixation durations and fewer fixations) to the card than when they behaved honestly. Our results suggest that when dishonesty pays, shifting attention away from undesirable information can serve as a self-deception strategy that allows individuals to serve their self-interests while maintaining a positive self-concept...

PURPOSE: Bone graft is often recommended as an adjuvant for treatment of scaphoid nonunions. However, recent literature has suggested that fibrous nonunion may be suited to treatment with rigid fixation without bone grafting. This work reported on outcomes of compression screw fixation for established scaphoid fibrous nonunions without bone graft. METHODS: Fourteen patients underwent surgical compression screw fixation without bone grafting of scaphoid fibrous nonunion between January 1, 2000, and December 31, 2012, with minimum follow-up until the time of clinical and radiographic healing...

PURPOSE: We explored whether fixational movements of the eye in the human visual system might enhance visual acuity, by effectively scanning the retinal image with its sparse receptive fields, rather than taking a static snapshot of the retinal image with a fixed sampling array. METHODS: We used an adaptive optics scanning laser ophthalmoscope to test orientation discrimination performance in three normal subjects while simultaneously imaging the underlying cone photoreceptor mosaic...

Andrew Rodriguez, Brittney Hernandez, Eriko Self
The appearance of inhibition of return (IOR), a phenomenon where invalid trials produce faster reaction times than valid trials, is delayed in target discrimination tasks at SOA of 700 ms compared to target localization tasks where it appears at SOA of 300 ms (Posner & Cohen, 1984; Lupiáñez, Milan, Tornay, Madrid, & Tudela, 1997). Our goal was to see whether deeper processing of the cue can accelerate the onset of IOR in target discrimination tasks (Gabay, Charras, Funes, Chica, & Henik, 2012), predicting that the cue processing will accelerate IOR's appearance at SOA of 100 ms...

Jing Chen, Matteo Valsecchi, Karl Gegenfurtner
The smooth pursuit system is known to have prediction mechanisms. In the present study we investigate whether the motor command for hand movements can be integrated in the prediction and used to anticipate pursuit. Some early studies have found that ongoing pursuit is more accurate and has fewer catch-up saccades when self-generated motion is tracked (e.g., Steinbach & Held, 1968). However, it is not clear whether anticipatory smooth pursuit can be observed before the hand motion starts. Five Observers were asked to place their index finger on a flat screen and to fixate it...

Visual perception across eye-movements is not veridical. As an example, saccadic eye-movements modulate the perceived location of a briefly flashed stimulus leading to a perceptual compression of space. During everyday-life eye movements occur also during navigation through an environment, thereby challenging the perception of self-motion direction (heading). Here we asked if saccades influence also the perceived heading in humans. We found a perisaccadic compression of perceived heading and aimed to identify a neural correlate of this new perceptual phenomenon in the animal model (macaque monkey)...

BACKGROUND: Cardiac pacemakers are limited by device-related complications, notably infection and problems related to pacemaker leads. We studied a miniaturized, fully self-contained leadless pacemaker that is nonsurgically implanted in the right ventricle with the use of a catheter. METHODS: In this multicenter study, we implanted an active-fixation leadless cardiac pacemaker in patients who required permanent single-chamber ventricular pacing. The primary efficacy end point was both an acceptable pacing threshold (≤2...
