To identify the prevalence and clinical features of detrusor underactivity (DU) in elderly men women presenting with lower urinary tract symptoms (LUTS).We reviewed 1,179 patients aged over 65 years who had undergone a urodynamic study for LUTS no neurological or anatomical conditions. DU was defined as bladder contractility index <100 maximal flow rate (Qmax) ≤12 ml/s combined pressure at Qmax ≤10 cmH(2)O women, respectively.Of patients, 40.2% 13.3% were classified having (p<0.001). Types...

Abstract Poly(lactic acid)‐grafted multiwalled carbon nanotubes (MWNT‐ g ‐PLA) were prepared by the direct melt‐polycondensation of L ‐lactic acid with carboxylic acid‐functionalized MWNT (MWNT‐COOH) and then mixed a commercially available neat PLA to prepare PLA/MWNT‐ ‐PLA nanocomposites. Morphological, thermal, mechanical, electrical characteristics nanocomposites investigated as function content compared those PLA, PLA/MWNT, PLA/MWNT‐COOH It was identified from FE‐SEM images that exhibit...

Objective To evaluate serial changes in renal function by investigating various clinical factors after radical nephrectomy ( RN ). Patients and Methods The study population consisted of 2068 consecutive patients who were treated at multiple institutions for cortical tumour without metastasis between 1999 2011. We measured the change estimated glomerular filtration rate eGFR ) during a 60‐month follow‐up period. over time analysed according to baseline ≥60 15–59 mL/min/1.73m 2 using linear...

A series of poly(butylene terephthalate-co-butylene 2,6-naphthalate) (P(BT-co-BN)) random copolymers were synthesized, and their cocrystallization behavior was investigated by differential scanning calorimetry (DSC) wide-angle X-ray diffraction (WAXD). The P(BT-co-BN) copolymers, which are found to be statistical show a single melting crystallization peak over the entire range copolymer composition have eutectic point in plot versus composition. WAXD patterns divided into two groups, i.e.,...

Korea is an endemic area for hepatitis B virus (HBV) infection. Reactivation of HBV a well-recognized complication in patients with chronic infection undergoing cytotoxic or immunosuppressive therapy, and there are some reports reverse seroconversion after HSCT. This study evaluated changes serology We reviewed the medical records 141 who had available serologic data autologous Patient information was retrospectively collected from BMT database. Before transplantation, 12 were positive...

Adoptive T-cell therapy is a promising approach to the immunotherapy of cancer, but for it be general cancer simple and standardized procedure producing tumor-specific CD8 T cells needed. On basis unique property 4-1BB (CD137), selective expression on activated cells, we have developed practical protocol produce antigen-specific from peripheral blood mononuclear cells. We proved feasibility this by isolating expanding cytomegalovirus-specific applied Epstein-Barr virus (EBV)-specific By...

Objectives: To evaluate the clinical prognosis of incontinence and to determine predictors for further recovery urinary continence in patients not achieving within 1 year after radical prostatectomy. Methods: A total 708 were evaluated regarding status at surgery from a prospectively maintained prostatectomy database. Of these, 73 (10.3%) did recover surgery. For these patients, number pads control assessed serially. Results: In factors associated with membranous urethral length, prostatic...

Objectives Mid-urethral sling (MUS) surgery for the treatment of urinary incontinence has been widespread since introduction tension-free vaginal tape in mid-1990s. The majority studies with short-term follow-up <2 years found no differences surgical outcomes according to body mass index (BMI). However, considering chronic influence obesity on pelvic floor musculature, it is cautiously speculated that higher BMI could increase stress and sub-urethral tape, possibly decreasing long-term...

When heated above room temperature, some crystalline polymorphs of the 1,3-bis(hydroxyalkylamino)-4,6-dinitrobenzenes (BDBn, n = 2-5), bis(hydroxyalkyl) analogues intramolecular charge-transfer molecule 1,3-diamino-4,6-dinitrobenzene, exhibit "dual" thermochromism: gradual color change from yellow to orange at lower temperatures, and sharp red higher temperatures. These two thermochromic changes are related different solid-state processes. allowed cool molecules with alkyl length (n) is...

The lower 1,3-bis(hydroxyalkylamino) homologues of the strong intramolecular X-type charge transfer (CT) system 1,3-diamino-4,6-dinitrobenzene (DADNB) exhibit reversible color change in solid state from yellow at room temperature (RT) to orange and red high (HT). To investigate structural prerequisites for occurrence this phenomenon, we prepared 10 new derivatives DADNB where hydroxyalkyl arms amino groups were replaced with substituents having different electronic steric profiles. Two...
