Abstract
INTRODUCTION Childbirth impacts sexual function in women, but few reports have addressed sexual function shortly after childbirth. AIM Using the Taiwan version of the Female Sexual Function Index (FSFIT), this study aimed to describe women's sexual function and to examine differences between groups in sexual function shortly after delivery. METHODS A prospective longitudinal investigation was performed in women who completed the FSFIT, a numeric analog scale, the Taiwan version of the Center for Epidemiologic Studies Depression Scale (CES-D), and a demographic questionnaire in a Taiwanese medical center at 3 days and 6 weeks postpartum. MAIN OUTCOME MEASURES Using a general linear model, differences were tested between groups, including those defined by delivery mode, type of feeding, depression score, pain score, and birth history. RESULTS After adjusting for covariates, (i) significant differences in sexual function and desire were found between the vaginal delivery and Cesarean section groups at day 3 and week 6 postpartum (P = 0.0419 and <0.0001, respectively); (ii) differences in desire and satisfaction between the tubal ligation and not groups were significant at both time points (P = 0.0346 and 0.0338); (iii) differences in sexual function and sexual activity or intercourse between low and high CES-D scores were significant at 6 weeks postpartum (P = 0.0040 and 0.0043, respectively); and (iv) differences between pain level groups in sexual activity or intercourse and desire were significant at 6 weeks (P = 0.0493 and 0.0004). At 3 days postpartum, significant differences between educational level and ethnic groups were observed (P = 0.0002 and 0.0414). CONCLUSIONS The results showed significant differences in sexual function shortly after delivery between groups based on delivery method, tubal ligation, depression, pain, ethnicity, and educational level. This information may help health professionals to be more aware of women's perception of sexuality and may foster sensitivity in assessing their sexual function after childbirth.

Abstract
AIM To investigate changes in urodynamic parameters after tolterodine treatment for female overactive bladder syndrome, especially in patients with voiding dysfunction. METHODS Between January and December 2006, 44 patients were enrolled for six months of treatment with tolterodine. Pre-treatment and post-treatment urodynamic studies were scheduled for the enrolled patients. RESULTS Among the remaining 33 patients (11 dropped out), bladder capacity (P < 0.001) and post-void residual urine (P = 0.009) increased, and functional urethral length (P = 0.049) and pad weight test (P = 0.03) decreased after treatment. Besides this, detrusor pressure at maximal urine flow, functional urethral length, maximal urethral pressure and maximal urethral closure pressure were less affected by tolterodine in patients with voiding dysfunction, compared to those without voiding dysfunction. CONCLUSIONS Tolterodine treatment increased bladder capacity and decreased urine leakage; however, some urodynamic parameters in patients with voiding dysfunction were less affected by tolterodine treatment.

Abstract
BACKGROUND Tuberculosis (TB) continues to be a major global health problem. Extra-pulmonary TB (EPTB) manifests with protean symptoms, and establishing a diagnosis is more difficult than pulmonary TB (PTB). SETTING A university-affiliated hospital in southern Taiwan. OBJECTIVE To analyse the risk factors for EPTB compared with PTB. DESIGN This retrospective study compared patients with EPTB and PTB in southern Taiwan by analysing their demographic data and clinical underlying diseases. Risk factors for EPTB were further analysed. RESULTS A total of 766 TB patients were enrolled in this study, with 102 (13.3%) EPTB and 664 (86.7%) PTB cases. Of the 766 patients, 3% of PTB patients had EPTB, while 19.6% of EPTB patients also had PTB. The most frequently involved EPTB site was the bone and joints (24.5%). The incidence of EPTB vs. PTB decreased significantly for each decade increase in patient age. Multivariate logistic regression analysis showed that being female, not being diabetic, having end-stage renal disease and not smoking were independent risk factors for EPTB. CONCLUSION This study defines the risk factors for EPTB compared with PTB. Awareness of these factors is essential for physicians to have a high index of suspicion for accurate and timely diagnosis.

Abstract
Increasing antibiotic resistance has become a worldwide challenge to the clinical treatment of infectious diseases. The identification of antibiotic resistance proteins (ARPs) would be helpful in the discovery of new therapeutic targets and the design of novel drugs to control the potential spread of antibiotic resistance. In this work, a support vector machine (SVM)-based ARP prediction system was developed using 1308 ARPs and 15587 non-ARPs. Its performance was evaluated using 313 ARPs and 7156 non-ARPs. The computed prediction accuracy was 88.5% for ARPs and 99.2% for non-ARPs. A potential application of this method is the identification of ARPs non-homologous to proteins of known function. Further genome screening found that ca. 3.5% and 3.2% of proteins in Escherichia coli and Staphylococcus aureus, respectively, are potential ARPs. These results suggest the usefulness of SVMs for facilitating the identification of ARPs. The software can be accessed at SARPI (Server for Antibiotic Resistance Protein Identification).

Abstract
OBJECTIVES To sequentially compare the postoperative urodynamic changes in patients with urodynamic stress incontinence (USI) who underwent tension-free vaginal tape (TVT) or transobturator tape (Monarc TOT) procedure. METHODS Between January 2001 and December 2005, 50 consecutive patients with USI who underwent TVT (n = 24) or TOT (n = 26) procedures were studied, and postoperative urodynamic changes were sequentially compared by one-way ANOVA test with Bonferroni's correction. RESULTS There were no significant between-group postoperative changes in urodynamic parameters of uroflowmetry, filling and voiding cystometry. However, the TVT group had a higher objective cure rate (100% vs. 69.2%, P = 0.004) by pad test, urethral closure pressure area [40.4 cm(2) H(2)O, 95% confidence interval (CI) = 22.3-58.5 cm(2) H(2)O vs. 3.9 cm(2) H(2)O, 95% CI = -10.9 to 18.7 cm(2) H(2)O, P = 0.036], and continence area (34.4 cm(2) H(2)O, 95% CI = 16.1-52.7 cm(2) H(2)O vs. -3.5 cm(2) H(2)O, 95% CI = -16.7 to 9.8 cm(2) H(2)O, P = 0.001) at 12 months than those of the TOT group. CONCLUSIONS This study demonstrated that tension-free vaginal tape and transobturator tape procedures had no significant difference of impact on bladder voiding and storage functions. However, this study demonstrated that TVT procedure resulted in a higher cure rate with a significantly increased urethral closure pressure area and continence area than did TOT procedure 12 months postoperatively. Thus, TVT procedure might be a better therapeutic choice to achieve continence than TOT.

Abstract
BACKGROUND To evaluate the effectiveness and toxicity of infusional cisplatin and weekly 24-hour infusion of high-dose fluorouracil plus leucovorin (P-HDFL) for the treatment of patients with stage IVB, recurrent and metastatic carcinoma of the cervix. PATIENTS AND METHODS A phase II study of P-HDFL in stage IVB, recurrent and metastatic carcinoma of cervix was initiated in January 2001. As of March 2007, a total of 21 patients were enrolled. Of these, 16 were evaluable for response. RESULTS The overall objective response rate was 25% [95% confidence interval (CI), 1.2-48.8%] with none achieving complete response. The median progression-free survival and overall survival for all 21 patients was 2.3 months (95% CI, 1.2-4.3 months) and 10.5 months (95% CI, 4.6-17.4 months), respectively. Toxicity was tolerable. The main problems were nausea/vomiting and anemia. CONCLUSION P-HDFL appears to be a moderately effective regimen with low toxicity for treating patients with advanced, recurrent and metastatic cervical cancer.

Abstract
Protein and peptide sequences contain clues for functional prediction. A challenge is to predict sequences that show low or no homology to proteins or peptides of known function. A machine learning method, support vector machines (SVM), has recently been explored for predicting functional class of proteins and peptides from sequence-derived properties irrespective of sequence similarity, which has shown impressive performance for predicting a wide range of protein and peptide classes including certain low- and non- homologous sequences. This method serves as a new and valuable addition to complement the extensively-used alignment-based, clustering-based, and structure-based functional prediction methods. This article evaluates the strategies, current progresses, reported prediction performances, available software tools, and underlying difficulties in using SVM for predicting the functional class of proteins and peptides.

Abstract
Support vector machines (SVM) and other machine-learning (ML) methods have been explored as ligand-based virtual screening (VS) tools for facilitating lead discovery. While exhibiting good hit selection performance, in screening large compound libraries, these methods tend to produce lower hit-rate than those of the best performing VS tools, partly because their training-sets contain limited spectrum of inactive compounds. We tested whether the performance of SVM can be improved by using training-sets of diverse inactive compounds. In retrospective database screening of active compounds of single mechanism (HIV protease inhibitors, DHFR inhibitors, dopamine antagonists) and multiple mechanisms (CNS active agents) from large libraries of 2.986 million compounds, the yields, hit-rates, and enrichment factors of our SVM models are 52.4-78.0%, 4.7-73.8%, and 214-10,543, respectively, compared to those of 62-95%, 0.65-35%, and 20-1200 by structure-based VS and 55-81%, 0.2-0.7%, and 110-795 by other ligand-based VS tools in screening libraries of >or=1 million compounds. The hit-rates are comparable and the enrichment factors are substantially better than the best results of other VS tools. 24.3-87.6% of the predicted hits are outside the known hit families. SVM appears to be potentially useful for facilitating lead discovery in VS of large compound libraries.

Abstract
Computational methods for predicting compounds of specific pharmacodynamic and ADMET (absorption, distribution, metabolism, excretion and toxicity) property are useful for facilitating drug discovery and evaluation. Recently, machine learning methods such as neural networks and support vector machines have been explored for predicting inhibitors, antagonists, blockers, agonists, activators and substrates of proteins related to specific therapeutic and ADMET property. These methods are particularly useful for compounds of diverse structures to complement QSAR methods, and for cases of unavailable receptor 3D structure to complement structure-based methods. A number of studies have demonstrated the potential of these methods for predicting such compounds as substrates of P-glycoprotein and cytochrome P450 CYP isoenzymes, inhibitors of protein kinases and CYP isoenzymes, and agonists of serotonin receptor and estrogen receptor. This article is intended to review the strategies, current progresses and underlying difficulties in using machine learning methods for predicting these protein binders and as potential virtual screening tools. Algorithms for proper representation of the structural and physicochemical properties of compounds are also evaluated.

Abstract
Factor Xa (FXa) inhibitors have been explored as anticoagulants for treatment and prevention of thrombotic diseases. Molecular docking, pharmacophore, quantitative structure-activity relationships, and support vector machines (SVM) have been used for computer prediction of FXa inhibitors. These methods achieve promising prediction accuracies of 69-80% for FXa inhibitors and 85-99% for non-inhibitors. Prediction performance, particularly for inhibitors, may be further improved by exploring methods applicable to more diverse range of compounds and by using more appropriate set of molecular descriptors. We tested the capability of several machine learning methods (C4.5 decision tree, k-nearest neighbor, probabilistic neural network, and support vector machine) by using a much more diverse set of 1098 compounds (360 inhibitors and 738 non-inhibitors) than those in other studies. A feature selection method was used for selecting molecular descriptors appropriate for distinguishing FXa inhibitors and non-inhibitors. The prediction accuracies of these methods are 89.1-97.5% for FXa inhibitors and 92.3-98.1% for non-inhibitors. In particular, compared to other studies, support vector machine gives a substantially improved accuracy of 94.6% for FXa non-inhibitors and maintains a comparable accuracy of 98.1% for inhibitors, based-on a more rigorous test with more diverse range of compounds. Our study suggests that machine learning methods such as SVM are useful for facilitating the prediction of FXa inhibitors.

Abstract
It is presently the right time for clarifying human papillomavirus (HPV)-associated cellular immunity and clinical implications before global HPV vaccination programs begin. Infection with oncogenic HPV associates with the progression of cervical neoplasia. Both cellular and humoral immune responses are essential for the clearance of HPV-associated cervical lesions. There is increasing evidence that the immune system plays a pivotal role in determining the outcome of HPV infection. Viruses and associated neoplastic cells are proposed to have evolved mechanisms to avoid immune attack. T-cell-mediated immune responses against oncogenic HPV are believed to play a central role in cervical carcinogenesis. The presence of HPV-specific cytotoxic T lymphocytes (CTL) in a majority of human cervical cancer patients provides an approach for further study of their functional role in modulating this malignancy. Tumor-infiltrating lymphocytes (TIL) develop as manifestations of the recognition and defense against malignant cells by the host immune system. Cancer cells may overcome immune surveillance, either by downregulating the proliferation of HPV-specific CTL, or altering the effector compositions of immune cells against HPV infections. TIL in the tumor microenvironment can be functionally inhibited and lose the ability of clonal proliferation as a result of depressed expression of IL-2Ralpha. The upregulation of inhibitory signaling relates to the modulation of the virus- and/or tumor-specific immune responses. Alteration of host genetic susceptibility may also lead to abnormal immune response as a general genomic instability resulting from virus persistence. Induction of HPV-specific immune responses is anticipated as an intimate point for the treatment of cervical neoplasia.

Eur J Obstet Gynecol Reprod Biol 2007; 136:121-5. [PMID: 17540494 DOI: 10.1016/j.ejogrb.2007.02.030] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2006] [Revised: 02/09/2007] [Accepted: 02/19/2007] [Indexed: 01/22/2023]
Abstract
OBJECTIVE The objective was to compare the sensitivity of the 20-min pad test by infusion of 250 ml of water with the strong-desire amount in the bladder in women with stress urinary incontinence (SUI). STUDY DESIGN Eighty-three women with SUI were enrolled between November 2005 and January 2006. The 20-min pad test by infusion of 250 ml of water was performed before urodynamic study (UDS). The strong-desire amount pad test was done after UDS. The results were analyzed by Pearson's chi(2) and Wilcoxon's signed-rank tests. RESULTS The sensitivity by infusion of the strong-desire amount was better than infusion of 250 ml of water in the 20-min pad test (P<0.001). In the quantitative study, the two pad tests had fair agreement and the pad weight results of the infusion of the strong-desire amount were statistically higher than the infusion of 250 ml of water (P=0.0004). CONCLUSIONS The infusion of the strong-desire amount had better sensitivity measured by the 20-min pad test in women with SUI compared with infusion of 250 ml of water in the bladder.

Shen PC, Lee SN, Liu BT, Chu FH, Wang CH, Wu JS, Lin HH, Cheng WTK. The effect of activation treatments on the development of reconstructed bovine oocytes. Anim Reprod Sci 2007; 106:1-12. [PMID: 17482390 DOI: 10.1016/j.anireprosci.2007.03.019] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2006] [Revised: 03/12/2007] [Accepted: 03/23/2007] [Indexed: 11/20/2022]
Abstract
The purpose of this study was to investigate the effect of different activation treatments on the development of IVM-derived and cloned bovine embryos. The effect of oocyte age (20h versus 24h after IVM) on the blastocyst rate was also investigated. No differences in the percentage of blastocyst development were observed between the oocytes matured for 20 and 24h (15% versus 27%, p>0.05). Reconstructed oocytes activated 4h after fusion (fusion before activation, FBA) had a higher blastocyst rate than those oocytes activated immediately after electrofusion (fusion and activation simultaneously, FAS) (26% versus 5%, p<0.01). Blastocyst rates were significantly greater (p<0.01) for the reconstructed oocytes activated by calcium ionophore (A23187) combined with 6-dimethylaminopurine (6-DMAP) (51.6%) than for those activated with cycloheximide (CHX) plus cytochalasin B (CB) treatment (1h, 8.2%; 5h, 14.3%). However, the blastocyst rates were similar among reconstructed oocytes activated by electric pulses and A23187 (30.5% versus 42.2%) or by A23187 and ionomycin (36.7% versus 33.3%) combined with 6-DMAP, respectively. Blastocysts that developed from reconstructed oocytes activated by A23187 and 6-DMAP resulted in three pregnancies (3/9) and one live birth from 18 embryos transferred to recipient cows. Genotypic analysis of six bovine microsatellite markers by polymerase chain reaction confirmed that the cloned calf was genetically identical to the nuclear donor. In conclusion, reconstructed oocytes that derived from oocytes exposed to activation treatment 4h after electrofusion are more likely to develop to the blastocyst stage. The best treatment to activate reconstructed bovine oocytes in this study was A23187 combined with 6-DMAP.
