Uropathogens in many Asian countries had high resistance to broad-spectrum antibiotics. Knowledge of regional and local resistance data and prudent use of antibiotics are important for proper management of UTI in Asian countries.
PurposeTo investigate the type of nocturia and concomitant voiding dysfunction (VD) and the effect of desmopressin treatment on nocturia in women.Materials and MethodsWe reviewed 84 women who experienced more than 2 nocturia episodes as recorded on a pretreatment frequency volume chart and who were treated with desmopressin. All patients underwent history taking, physical examination, urinalysis, International Prostate Symptom Score assessment, completion of a urinary sensation scale, and completion of a 3 day frequency volume chart. Nocturia was divided into nocturnal polyuria (NP), reduced nocturnal bladder capacity (RNBC), and mixed type. After treatment with desmopressin, a reduction in nocturia of over 50% compared with baseline was regarded as effective.ResultsAmong 84 women, the most common concomitant VD was overactive bladder (OAB, 60.7%). NP was observed in 70.2% (59/84) of the women, RNBC in 7.1% (6/84), and mixed type in 22.6% (19/84). After medication with desmopressin, 73 women (86.9%) showed a significantly reduced number of nocturia episodes (1.4±1.5) compared with baseline (3.7±1.3, p<0.05). Eleven women (13.1%) did not show improvement. Of the 73 women who showed improvement, 41 women showed a reduction of more than 50% over baseline, and these women had a lower baseline urgency grade.ConclusionsIn the majority of women, nocturia coexisted with other VD such as OAB. Treatment with desmopressin effectively reduced the nocturia. However, other lower urinary tract symptoms (LUTS) such as urgency may reduce the effect of desmopressin. Therefore, consideration of concomitant LUTS seems to be necessary to increase the treatment effect of desmopressin on nocturia in women.
4-Phenylbutyric acid (PBA)-installed hyaluronic acid (HA)-based nanoparticles (NPs) were developed for amplifying the anticancer potential of curcumin (CUR) for lung cancer therapy.
Without using biochemical agents, in this study, we sought to investigate the potential of controlling the differentiation of mesenchymal stem cells (MSCs) into a specific cell type through the use of 3D co-culturing and mechanical stimuli. MSCs and primary cultured chondrocytes were separately encapsulated into alginate beads, and the two types of beads were separated by a membrane. For the investigation a computer-controllable bioreactor was designed and used to engage intermittent hydrostatic pressure (IHP). Five different magnitudes (0.20, 0.10, 0.05, 0.02 MPa and no stimulation) of IHP were applied. The stimulation pattern was the same for all groups: 2 h/day for 7 days starting at 24 h after seeding; 2 and 15 min cycles of stimulating and resting, respectively. Biochemical (DNA and GAG contents), histological (Alcian blue), and RT-PCR (Col II, SOX9, AGC) analyses were performed on days 1, 5, 10, and 20. The results from these analyses showed that stimulation with higher magnitudes of IHP (≥0.10 MPa) were more effective on the proliferation and differentiation of co-cultured MSCs. Together, these data demonstrate the potential of using mechanical stimulation and co-culturing for the proliferation and differentiation of MSCs, even without biochemical agents.
Since the PAMELA results on the "anomalously" high positron fraction and the lack of antiproton excess in our Galaxy, there has been a tremendous number of studies advocating new types of dark matter, with larger couplings to electrons than to quarks. This raises the question of the production of dark matter particles (and heavy associated coloured states) at LHC. Here, we explore a very simple benchmark dark matter model and show that, in spite of the agreement between the PAMELA antiproton measurements and the expected astrophysical secondary background, there is room for large couplings of a WIMP candidate to heavy quarks. Contrary to what could have been naively anticipated, the PAMELAp/p measurements do not challenge dark matter model building, as far as the quark sector is concerned. A quarkophillic species is therefore not forbidden. Owing to these large couplings, one would expect that a new production channel opens up at the LHC, through quark-quark and quark-gluon interactions. Alas, when the PDF of the quark is taken into account, prospects for a copious production fade away.
