BACKGROUND The aim of this study was to compare pelvic floor muscle (PFM) strength using transvaginal digital palpation in healthy continent women in different age groups, and to compare the inter- and intra-rater reliability of examiners performing anterior and posterior vaginal assessments. METHODS We prospectively studied 150 healthy multiparous women. They were distributed into four diffe...
Orally administered probiotic micro-organisms are able to regulate the exacerbated immune response during the antigenic sensitisation process. The aim of the present study was to evaluate the potential efficacy of probiotic fermented milk (PFM) in preventing or treating allergy in an experimental model, and to investigate its underlying mechanisms. Ovoalbumin (OVA)-sensitised BALB/c mice were f...
The increased contrast to noise ratio available at Ultrahigh (7T) Magnetic Resonance Imaging (MRI) allows mapping in space and time the brain’s response to single trial events with functional MRI (fMRI) based on the Blood Oxygenation Level Dependent (BOLD) contrast. This thesis primarily concerns with the development of techniques to detect and characterize single trial event-related BOLD respo...
OBJECTIVES The main objective was to determine how the depth of probe placement affects functional and resting bioelectrical activity of the PFM and whether the recorded signal might be dependent on the direction in which the probe is rotated. PARTICIPANTS The study comprised of healthy, nulliparous women between the ages of 21 and 25. OUTCOME MEASURES Bioelectric activity of the PFM was re...
Protein–energy malnutrition (PEM) causes a significant impairment of the immune system, the thymus being one of the most affected organs. It has been demonstrated that the administration of probiotic fermented milk (PFM) recovered the intestinal barrier, histological alterations and mucosal and systemic immune functions in a non-severe malnutrition model using BALB/c mice. The aim of the presen...
This topic discusses the trade-offs between fixed-frequency pulse-width modulation (PWM) and pulsefrequency modulation (PFM) for portable DC/DC converter applications. PWM converters offer the benefit of predictable operating frequency, which may simplify the design of circuitry that suppresses electromagnetic interference (EMI). They also offer low output ripple characteristics and high effici...
PURPOSE Porcelain fused to metal (PFM) crowns provide the best treatment option for teeth that have a large or defective restoration. More than 20% of teeth with PFM crowns or bridges require non-surgical root canal treatment (NSRCT). This may be due to the effect of restorative procedures and the possible leakage of bacteria and or their by-products, which leads to the demise of the tooth pulp...
BACKGROUND BAY 81-8973 is a full-length, unmodified, recombinant human factor VIII (FVIII) for the treatment of hemophilia A. OBJECTIVE The aim of this study was to compare the pharmacokinetic (PK) profile of BAY 81-8973 with antihemophilic factor (recombinant) plasma/albumin-free method (rAHF-PFM) PATIENTS/METHODS: In this phase I, open-label, crossover study, men aged 18-65 years with sever...
In this paper we discuss an application of CMOS photo-sensor array chip using pulse frequency modulation (PFM) to sub-retinal implantation to recover human vision. PFM with integration mode as photo-sensing circuit is used to realize enough dynamic range and compatibility with signals in real retina. To effectively stimulate the retinal cells, we have designed a PFM circuit with limited bandwid...
