Why do female bank voles, Clethrionomys glareolus, mate multiply?
2007
Females of many species actively engage in multiple mating, with either a single male or several males, but the adaptive function of this behaviour is often unclear. We conducted a laboratory experiment on a small mammal species, the bank vole, testing the possible benefits of multiple mating on a female's short-term reproductive success (pregnancy rate, litter size and early postnatal survival). Such benefits may affect a female's fitness either directly or indirectly (genetic benefit). We assigned females to three treatments: a single mating treatment in which females mated once with a single male and two multiple mating treatments in which females mated either twice with a single male or…
Association between urinary incontinence and frailty: a systematic review and meta-analysis
2018
Purpose: Urinary incontinence (UI) and frailty are common geriatric syndromes. Although literature increasingly supports a relationship between these two conditions, no systematic review and meta-analysis has been performed on this topic. Therefore, we aimed to investigate the potential association between UI and frailty, through a meta-analytic approach. Methods: A systematic search in major databases was undertaken until 15th March 2018 for studies reporting the association between UI and frailty. The prevalence of UI in people with frailty (vs. those without) was pooled through an odds ratio (OR) and 95% confidence intervals (CIs), with a random-effects model. The other outcomes were sum…
Induced abortion and risk of small-for-gestational-age birth.
2007
Objective: To investigate the possibility of an association between previous induced abortion and subsequent birth of a small-for-gestational-age (SGA) infant. Design: Case-control study. Setting: General and university hospitals. Methods: Cases were 555 women who delivered SGA babies. Controls were 1966 women who gave birth at term (>37 weeks of gestation) to healthy infants of normal weight on randomly selected days at the hospital where cases had been identified. All women in the case and control categories were interviewed on the obstetric wards by one of a team of six interviewers. During the interviews, information was obtained regarding general socio-demographic factors, personal cha…
L-citrulline ameliorates pathophysiology in a rat model of superimposed preeclampsia
2021
AbstractPreeclampsia, characterized by hypertension, proteinuria, and fetal growth restriction, is one of the leading causes of maternal and perinatal mortality. By far, there is no effective pharmacological therapy for preeclampsia. The present study was conducted to investigate the effects of L-citrulline supplementation in Dahl salt-sensitive rat, a model of superimposed preeclampsia. Parental DSSR were treated with L-citrulline (2.5 g/L in drinking water) from the day of mating to the end of lactation period. Blood pressure of the rats was monitored throughout pregnancy and markers of preeclampsia were assessed. Endothelial function of the pregnant DSSR was assessed by wire myograph. L-…
Application of liquid-liquid partition chromatography in the simultaneous purification of sex-hormone-binding globulin and corticosteroid-binding glo…
1987
Two human serum proteins, corticosteroid-binding globulin (CBG) and sex-hormone-binding globulin (SHBG), were purified to homogeneity by the application of a combination of three different modes of chromatography. Human pregnancy serum was fractionated with ammonium sulphate. SHBG (50% pellet) and CBG (80% pellet) were then purified by affinity chromatography on tresyl-activated Sepharose with 15-aminopentadecanoic acid (for SHBG) and 1,12-diaminododecane (for CBG) as spacers and 17 zeta-aminoethyl-5 alpha-androstan-3 beta,17-diol (for SHBG) and 17 alpha-hydroxy-4-androsten-3-one-17 beta-carboxylic acid (for CBG) as specific ligands for these two proteins. The eluate was injected into a Mon…
Intracytoplasmic Testicular Sperm Injection: An Effective Treatment for Otherwise Intractable Obstructive Azoospermia
1995
AbstractPurpose: We evaluated the efficacy of intracytoplasmic sperm injection with testicular spermatozoa.Materials and Methods: Intracytoplasmic sperm injection was performed with spermatozoa obtained from testicular biopsy specimens in 15 patients with obstructive azoospermia, in whom standard microsurgical procedures were not feasible or had previously failed.Results: Fertilization was achieved in 14 to 15 cycles. Mean fertilization rate per cycle was 63.6 percent. Four clinical pregnancies occurred, for a pregnancy rate of 26.7 percent per started cycle and 28.6 percent per transfer.Conclusions: Intracytoplasmic testicular sperm injection is followed by high fertilization rates, and of…
Sperm Telomere Length in Men with Normal and Abnormal semen Parameters. A Pilot Study
2019
Objective: Male infertility is a growing social problem. The measurement of telomere length may be a new marker that can help to assess reproductive age of males and assess the chances of in vitro fertilization. Aim: The aim of our study was to investigate whether there are any differences between telomere length in men with normal and abnormal semen parameters. Materials and Methods: Telomere length was analyzed in 17 patients with normal and 28 patients with abnormal semen parameters using the telomeric repeat amplification protocol and Quantitative Real-Time Polymerase Chain Reaction (qPCR). Results: Mean sperm telomere length in all donors was 49±24kbp per haploid genome. However, patie…
Quality of Life and Health in Patients with Urinary Diversion: A Comparison of Incontinent versus Continent Urinary Diversion
1997
Objective: To compare the quality of life and health in patients with incontinent and continent urinary diversions, in correlation with the initial diagnosis, diversion-related symptoms, psychological status and employment status. Materials and Methods: 81 patients (64% male and 36% female) with a mean age of 55 years (18-65 years) were included in this retrospective study. A total of 27 had an incontinent urinary diversion (group A) and 54 a continent diversion (group B). The initial diagnosis was malignant tumor in 75% (n = 61) and nontumor disease in 25% (n = 20). A structured interview and psychometric instrument assessment of the quality of life as well as somatic and psychological sym…
Can antepartum computerized cardiotocography predict the evolution of intrapartum acid-base status in normal fetuses?
2004
Background. To study the relationship between antepartum computerized cardiotocography (cCTG) and the evolution of intrapartum fetal acid-base balance in a low-risk population. Methods. Forty-nine healthy fetuses were prospectively followed up by antepartum cCTG (Oxford System 8002), fetal scalp blood sampling at the onset of the active phase of dilatation (3 cm) and at the beginning of the second stage of labor (10 cm) and study of acid-base status at birth in the umbilical cord. Correlation studies and linear regression analysis were performed. Results. Normal prelabor cCTG was followed by normal fetal acid-base balance in the different study periods. No relationship was found between cCT…
Quality-of-Life Outcomes in Female Patients With Ileal Conduit or Orthotopic Neobladder Urinary Diversion: 6-Month Results of a Multicenter Prospecti…
2022
Radical cystectomy (RC) often affects patients’ life as this surgery is a traumatic and invasive event for the patients, with drawbacks on their daily, social, working, and sex life. Such changes in the quality of life (QoL) of patients are commonly studied through retrospective clinical evaluations and rarely with longitudinal studies. To date, studies focusing on functional outcomes, sexual function, and health-related QoL for female patients are lacking. We evaluated 37 patients using EORTC QLQ-C30 (QLQ-30) and Short-Form 36 (SF-36) questionnaires, before and after surgery, at 3 and 6 months of follow-up. The mean values for the emotional functioning in QLQ-C30 as well as the mental heal…
