The challenge of developing scaffolds to reconstruct critical-sized calvarial defects without the addition of high levels of exogenous growth factor remains relevant. Both osteogenic regenerative efficacy as well as suitable mechanical properties for the temporary scaffold system are of importance. In this study, a Mg alloy mesh reinforced polymer/demineralized bone matrix (DBM) hybrid scaffold was designed where the hybrid scaffold was fabricated by a concurrent electrospinning/electrospraying of poly(lactic-co-glycolic) (PLGA) polymer and DBM suspended in hyaluronic acid (HA)...

The pea leafminer (Liriomyza huidobrensis) is a notorious pest of vegetables and ornamental plants worldwide. Despite a large number of studies on its biology and ecology, the courtship behavior and sexual communication of this species remain unclear. Here, we studied the vibrational communication in the sexual interaction of the pea leafminer. On host plant leaves, females and males behaviorally displayed the bobbing-quivering alternation, which finally led to copulation. Moreover, records of laser vibrometry revealed three-signal duets underlying the behavioral alternation...

L Zogbi
BACKGROUND: The Lichtenstein technique is used worldwide because of its rapid learning curve, good results and low recurrence rates. In this approach, a lateral tie-shaped incision is made on the mesh, involving the spermatic funiculus and thus correcting the deep inguinal ring defect by narrowing it. The lateral tie, however, does not prevent the wrinkling of the upper portion of the mesh that is caused by the arched shape of the inguinal ligament, where the lower edge of the prosthesis is sutured...

Background: The formation of hepatic hemangiomas (HH) is associated with VEGF and IL-7 that alter conduit arteries and small arterioles. To our knowledge, there are no studies to investigate the effects of HH on the hemodynamics in conduit arteries. The aim of the study is to perform morphometric and hemodynamic analysis in abdominal conduit arteries and bifurcations of HH patients and controls. Methods: Based on morphometry reconstructed from CT images, geometrical models were meshed with prismatic elements for the near wall region and tetrahedral and hexahedral elements for the core region...

Wildlife attacks on humans and economic losses often result in reduced support of local communities for wildlife conservation. Information on spatial and temporal patterns of such losses in the highly affected areas contribute in designing and implementing effective mitigation measures. We analyzed the loss of humans, livestock and property caused by wildlife during 1998 to 2016, using victim family's reports to Chitwan National Park authorities and Buffer Zone User Committees. A total of 4,014 incidents were recorded including attacks on humans, livestock depredation, property damage and crop raiding caused by 12 wildlife species...

Incisional hernias following ostomy reversal occur frequently. Incisional hernias at the site of a previous stoma closure can cause significant morbidity, impaired quality of life, lead to life-threatening hernia incarceration or strangulation and result in a significant financial burden on health care systems Despite this, the evidence base on the subject is limited. Many recognised risk factors for the development of incisional hernia following ostomy reversal are related to patient factors such as age, malignancy, diabetes, COPD, hypertension and obesity, and are not easily correctable...

The use of synthetic mesh in the abdominal compartment has recently become a topic of debate as high profile public cases have called into question their safety. Several case reports have demonstrated significant complications due to intra-abdominal mesh. Furthermore, some studies have suggested that the rates of these severe complications are underestimated. We present the case of a patient who developed an enteroenteric and enterocutaenous fistulae, an abdominal wall collection and an intraperitoneal inflammatory mass from intraluminal migration of a synthetic mesh inserted during laparoscopic incisional hernia repair...

A simple route to fabricate defect-free Ag-nanoparticle-carbon-nanotube composite-based high-resolution mesh flexible transparent conducting electrodes (FTCEs) is explored. In the selective photonic sintering-based patterning process, a highly soft rubber or thin plastic substrate is utilized to achieve close and uniform contact between the composite layer and photomask, with which uniform light irradiation can be obtained with diminished light diffraction. This well-controlled process results in developing a fine and uniform mesh pattern (≈12 μm)...

AIMS: Continent urinary diversion is preferred by some patients and orthotopic urinary diversion (OUD) has become the procedure of choice for most men following cystectomy for invasive bladder cancer. OUD in women, however, is less common, likely due to a high rate of hypercontinence (HC), potentially from lax support of pelvic structures similar to pelvic organ prolapse. As such, we evaluated if abdominal sacrocolpopexy (ASC) at the time of OUD in women led to decreased rates of HC. METHODS: A retrospective review of all female patients receiving OUD by a single surgeon and ASC was performed...

Here we present a 32-y-old rhesus macaque (Macaca mulatta) with a large recurrent ventral incisional hernia. The initial surgery included midline celiotomy for treatment of endometriosis, in which the animal developed a hernia that was repaired with interposition of mesh. Hernia recurrence at 1 y resulted in a defect measuring 7 × 13 cm, with loss of abdominal domain. Skin breakdown was noted with areas of exposed mesh through the skin with associated acute on chronic infection. Clinically, the animal was lethargic, not eating, and failing to thrive...

A thermally most stable molecular self-assembly in water (nanocube), whose decomposition temperature is 142 °C, has been developed by the design of a gear-shaped amphiphile (GSA) with an indented hydrophobic surface, even though the nanocube is stabilized only by van der Waals (vdW) and cation-pinteractions and the hydrophobic effect. The introduction of an electron-donating substituent in one of the benzene rings in GSA increased the decomposition temperature by 12 K, which is due to the stronger cation-p interactions between the benzene ring and positively charged pyridinium rings and the tighter molecular meshing between the GSAs in the nanocube...
