OBJECTIVE: A single-operator, long-term (15 years) experience on a sling technique that allows a postoperative adjustment of its tension is presented to retrospectively report the objective and subjective outcomes in the treatment of female stress urinary incontinence (SUI). The readjustment option prevents the need of a reoperation in case of relapse with great compliance of the patients. MATERIALS AND METHODS: Indications for surgical tratment of SUI by ReMeEx included patients affected with not only true intrinsic sphyncteric deficency (ISD) and fixed urethra but also mild urethral hypermobility, previous incontinence surgery and relapsing conditions such as diabetes and obesity...

<p>Surgical defects located within 5 mm of the nasal alar margin are at risk for alar elevation or collapse of the external nasal valve during wound healing. To reduce the chance of such complications, free cartilage grafts may be used as part of the reconstruction. However, if the defect is large enough so that the free cartilage graft does not fill most of the defect, wound contraction can still lead to alar displacement. In these situations, skin may need to be recruited from either the forehead or cheek in the form of an interpolation flap to cover both the free cartilage graft and the residual cutaneous defect...

Serpentinization is a widespread geochemical process associated with aqueous alteration of ultramafic rocks that produces abundant reductants (H2 and CH4) for life to exploit, but also potentially challenging conditions, including high pH, limited availability of terminal electron acceptors, and low concentrations of inorganic carbon. As a consequence, past studies of serpentinites have reported low cellular abundances and limited microbial diversity. Establishment of the Coast Range Ophiolite Microbial Observatory (California, U...

Loops are ubiquitous topological elements formed when proteins simultaneously bind to two non-contiguous DNA sites. While a loop-mediating protein may regulate initiation at a promoter, the presence of the protein at the other site may be an obstacle for RNA polymerases (RNAP) transcribing a different gene. To test whether a DNA loop alters the extent to which a protein blocks transcription, the lac repressor (LacI) was used. The outcome of in vitro transcription along templates containing two LacI operators separated by 400 bp in the presence of LacI concentrations that produced both looped and unlooped molecules was visualized with scanning force microscopy (SFM)...

ortho-Carbonylarylacetylenols have been employed for the synthesis of dihydronaphthofurans via AgTFA-catalyzed annulation reaction. A broad range of substrates both ortho-keto- and ortho-formylarylacetylenols could be employed in this transformation providing the desired products in good yields. However, the reaction pathways of these two substrates are different. The reaction of the ketone precursors could directly lead to the desired products in a single operation while the reaction of the aldehyde precursors required a one-pot two-step approach, without isolation of the bicyclic acetal intermediates...

BACKGROUND: Laparoscopy offers the benefits of minimally invasive surgery and faster recovery. Acute surgical patients may potentially benefit from the greatest advantages of emergency laparoscopy, even more clinically relevant in acute rather than elective patients. Fashioning a laparoscopic intra-corporeal anastomosis (ICA) after emergent colorectal resection, whenever technically feasible and non-contraindicated for the patients' general and hemodynamic condition, represents the most challenging technical skill to be learned...

R Guy Reeves, Diethard Tautz
The intense focus on studying human height has done more than any other genetic analysis to advance our understanding of the heritability of highly complex phenotypes. Here we describe in detail the properties of a previously unexplored trait in Drosophila melanogaster that shares many salient properties with human height. The total length of the pupal case varies between 2.8 and 3.9mm among natural variants and we report that it is among the most heritable traits reported in this species. We have developed a simple semi-automatic phenotyping system with which a single operator can reliably score >5000 individuals in a day...

BACKGROUND: Early diagnosis of malignant axillary nodes in breast cancer guides the extent of axillary surgery: patients with known axillary malignancy receive a more extensive single operation at the same time as surgery to their breast. A multicentre randomised controlled trial assessed whether a Computed Tomography (CT) scan of the axilla could more accurately diagnose malignant axillary lymph node involvement in patients with newly diagnosed breast cancer when compared to usual care...

OBJECTIVE: The contribution of therapeutic ureteroscopy done by Perez Castro in 1980 varied the management algorithm for ureteral lithiasis worldwide. The techniques of Retrograde Ureteroscopy and transrenal antegrade ureteroscopy led to the abandonment of open surgery for the treatment of ureteral lithiasis. Only Shock wave lithotripsy has maintained similar success rates in selected cases. METHODS: Descriptive analysis of the semirigid and flexible ureteroscopy techniques performed in our department over the last 10 years giving detail on the technique and safety tips to increase the efficacy and efficiency of ureteroscopy...

Jason Deforest Jones, Rishi Pawa
Mirizzi syndrome is an exceptionally rare diagnosis with an annual incidence of less than 1% in developed countries. In this disease process, stone burden in the cystic duct or gallbladder neck leads to common hepatic duct obstruction, either by mechanical compression or secondary inflammation. Mirizzi syndrome is classified into one of four types based on the presence and severity of cholecystobiliary fistulization. Treatment is primarily surgical in nature and largely dictated by the type of Mirizzi syndrome encountered...

The utilization of renewable biomass resources to produce high-value chemicals by enzymatic processes is beneficial for alternative energy production, due to the accelerating depletion of fossil fuels. As immobilization techniques can improve enzyme stability and reusability, a novel magnetic cross-linked cellulase aggregate has been developed and applied for biomass bioconversion. The crosslinked aggregates could purify and immobilize enzymes in a single operation, and could then be combined with magnetic nanoparticles (MNPs), which provides easy separation of the materials...

INTRODUCTION: Webbed neck deformity (WND) can have significant functional and psychosocial impact on the developing child. Surgical correction can be challenging depending on the extent of the deformity, and patients often also have low posterior hairlines requiring simultaneous correction. Current surgical techniques include various methods of single-stage radical excision that often result in visible scar burden and residual deformity. There is currently no general consensus of which technique provides the best outcomes...
