Voiding dysfunction (VD) after sling operation is not uncommon. Sling revisions by incision/excision are usually effective; however, they may result in recurrent stress urinary incontinence (SUI). We aimed to evaluate continence status after an innovative sling revision procedure that preserves the integrity of the sling.

Objective: We present a case of spontaneous abdominal wall endometriosis presenting as a painless nodular mass in a woman with no prior history of abdominal surgery.
Case Report: Abdominal wall endometriosis (AWE) is an uncommon form of endometriosis, usually arising due to a past history of cesarean section or abdominal hysterectomy. However, in rare cases, abdominal wall endometriosis can arise in women with no prior history of abdominal surgery.
Background: The presence of reactive and strong pelvic floor muscle (PFM) activities is supposed to be associated with better urinary and sexual functions in female stress urinary incontinence (SUI).
Aim: This study was to explore the association of baseline PFM activities, both volitional and reflex, with urinary and sexual functions in women with SUI but who had no experience of PFM training programs before.
Methods: Secondary analysis of a prospectively maintained database identified 125 sexually active women with SUI who had met the eligibility criteria.
Objectives: To evaluate the short-term evolution and risk factors of overactive bladder (OAB) in community-dwelling male residents aged 40 years and above in central Taiwan.
Methods: This was a 3-year longitudinal cohort study. From January 2012 to December 2012, community residents aged 40 years and above, living in central Taiwan, were invited to participate in this study.
Background: Pyridoxal 5'-phosphate (PLP) is the primary circulatory form of vitamin B6, an essential cofactor for numerous biochemical enzymatic reactions. Conventional PLP analysis using high-performance liquid chromatography (HPLC) with fluorescence requires derivatization and long injection-to-injection time. Development of high-throughput LC-MS/MS assays is desirable.

We aimed to investigate the effect of nutritional education, and/or protein supplementation on nutritional biomarkers in hypoalbuminemic peritoneal dialysis patients. A quasi-experimental study was conducted in two dialysis centers at Taipei Tzu Chi Hospital and Shin Kong Wu Ho-Su Memorial Hospital.

However, CBPR often has shortcomings when applied to population-level policy and practice interventions, including a focus on single communities and a lack of focus on policy change. At the same time, community trials focused on policy have shortcomings, including lack of stakeholder involvement in framing research questions and modest engagement in study implementation and interpretation and dissemination of results.

These therapies provide a significant survival benefit to patients with metastatic colorectal cancer with wild-type RAS. A single point mutation in the ectodomain of EGFR (S468R) confers acquired or secondary resistance in cetuximab treated patients, which is not observed in panitumumab-treated patients.

The Guide to Community Preventive Services recommends reducing the density of alcohol outlets - the number of physical locations in which alcoholic beverages are available for purchase either per area or per population - through the use of regulatory authority as an effective strategy for reducing excessive alcohol consumption and related harms. We briefly review the research on density of alcohol outlets and public health and describe the powers localities have to influence alcohol outlet density.

Here, we present kinetic, thermodynamic, and structural rationale for the remarkable potency of a new class of MDM2 inhibitors, the piperidinones. While these compounds bind to the same site as previously reported for small molecule inhibitors, such as the Nutlins, data presented here demonstrate that the piperidinones also engage the N-terminal region (residues 10-16) of human MDM2, in particular, Val14 and Thr16.

The ubiquitin proteasome pathway (UPP) has been implicated in a number of pathogenic diseases: cancer, inflammation, metabolic disorders, and viral infection. The human genome contains well over 500 genes encoding proteins involved in the UPP. Ubiquitin ligases (E3s) comprise the largest subset of these genes, and together with an E2 partner, provide the substrate selectivity required for regulating cellular proteins through the covalent attachment of ubiquitin.

Methods: One hundred twenty-four women with SUI were retrospectively investigated.
In aqueous solution, azaquinolone inhibitors bind to prolyl 4-hydroxylase in two different orientations, as first detected by (19)F spectroscopy. This contrasts with the crystallographic structure where only one orientation has been determined. Dissection of the metal binding properties of the enzyme allowed structures of both complexes to be obtained in solution from (19)F and (13)C dipolar shifts in a labeled ligand.

Methods: We retrospectively reviewed the records of 707 women who had primary SUI. Clinical data for analysis included Ingelman-Sundberg scales, 1-h pad tests, incontinence-related QoL questionnaires comprising short forms of the Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7), ultrasound assessment of urethral support and urethral sphincter function determined by maximum urethral closure pressure and Valsalva leak point pressure.
Tumor protein 53 (p53) is a critical regulator of cell cycle and apoptosis that is frequently disabled in human tumors. In many tumor types, p53 is deleted or mutated, but in others p53 is inactivated by overexpression or amplification of its negative regulator mouse double minute 2 (MDM2). A high-throughput screening effort identified 6,7-bis(4-bromophenyl)-7,12-dihydro-6H-chromeno[4,3-d][1,2,4]triazolo[1,5-a]pyrimidine as a potent inhibitor of the MDM2-p53 protein-protein interaction.

Materials And Methods: A total of 118 women with the symptomatic and urodynamic evidence of stress urinary incontinence were recruited in a 3-year period from tertiary referral urogynecology clinics. Under the oral instruction of strong coughing involuntary pelvic floor muscle contraction was detected using introital ultrasound in real-time and cine loop modes.
Proprotein convertase subtilisin/kexin type 9 (PCSK9) regulates serum LDL cholesterol (LDL-C) by interacting with the LDL receptor (LDLR) and is an attractive therapeutic target for LDL-C lowering. We have generated a neutralizing anti-PCSK9 antibody, mAb1, that binds to an epitope on PCSK9 adjacent to the region required for LDLR interaction. In vitro, mAb1 inhibits PCSK9 binding to the LDLR and attenuates PCSK9-mediated reduction in LDLR protein levels, thereby increasing LDL uptake.

To determine if the recruitment of the protractors and retractors of the hindlimb are compatible with this hypothesis, we monitored changes in the recruitment of eleven muscles that span the hip joint to controlled manipulations of locomotor forces in trotting dogs. The results indicate that the primary retractor muscles of the hindlimb produce a small retraction moment at the hip joint early in the support phase during trotting at constant speed on a level surface.

Hydroxylation of conserved prolyl residues in the HIF-alpha subunit, catalyzed by HIF prolyl-hydroxylases (PHDs), signals for its proteasomal degradation. The requirement of the PHDs for dioxygen links changes in dioxygen levels with the transcriptional regulation of the gene array that enables the cellular response to chronic hypoxia; the PHDs thus act as an oxygen-sensing component of the HIF system, and their inhibition mimics the hypoxic response.
