OBJECTIVE To evaluate a new fully automated assay measuring antimüllerian hormone (AMH; Roche Elecsys) against antral follicle count in women of reproductive age. DESIGN Prospective cohort study. SETTING Hospital infertility clinics and academic centers. PATIENT(S) Four hundred fifty-one women aged 18 to 44 years, with regular menstrual cycles. INTERVENTION(S) None. MAIN OUTCOME MEASU...

OBJECTIVE This retrospective study determined for the first time the role of baseline antral follicle count (AFC) and serum anti-Mullerian hormone (AMH) level in the first in-vitro fertilisation (IVF) cycle in predicting cumulative live birth from one stimulation cycle. METHODS We studied 1,156 women (median age 35 years) undergoing the first IVF cycle. Baseline AFC and AMH level on the day b...

This paper highlights a simulation study involving the application of an active force control (AFC) strategy to suppress vibration on the rear handle of a handheld tool. The research was carried out to investigate the performance in terms of vibration reduction capability of a feedback controller employing AFC-based schemes on a selected powered portable machine (Hedge Trimmer Maruyama model Ht...

This paper discusses acoustic feedback effects in active noise control (ANC) and proposes an improved performance online adaptive feedback canceller (AFC). The online AFC is ineffective if the noise input is narrowband. The proposed method uses the prewhitening filter in the weight adaptation path of both AFC and ANC. The computer simulations show that the proposed method of ANC with online AFC...

The characteristics of antibody-forming cell (AFC) progenitors lacking previous contact with specific antigen (virgin AFC progenitors) has been studied using sedimentation velocity and buoyant density separation for the investigation of physically distinct B-cell subpopulations. Functional characterization of isolated subsets was made using a quantitative adoptive immune assay for the IgM AFC p...

Depletion of the ovarian reserve is associated with reproductive senescence in mammalian females, and there is a positive relationship between the size of the ovarian reserve and the number of antral follicles on the surface of the ovary. Therefore, we conducted a series of experiments to investigate the influence of stage of the estrous cycle, age, and birth weight on antral follicle counts (A...

OBJECTIVE The timing of menopause is associated with multiple chronic diseases. Tools that predict this milestone have relevance for clinical and research purposes. Among infertile women, a positive relationship exists between antral follicle count (AFC) and response to controlled ovarian hyperstimulation, a marker of ovarian reserve. However, an age-independent relationship between AFC and men...

Active Fiber Composites (AFC) manufactured at EMPA with commercially available piezoelectric ceramic fibers have been investigated for their potential use as sensors and emitters in various applications. The AFC elements have been evaluated with methods derived from the characterization of ultrasonic transducers and acoustic emission (AE) sensors. Electrical impedance measurements as a function...

BACKGROUND The objective of our study was to identify the correlations between the tests currently used in ovarian reserve assessment: anti-Mullerian hormone (AMH), follicle stimulating hormone (FSH) and antral follicle count (AFC) and to distinguish the most reliable markers for ovarian reserve in order to select an adequate strategy for the initial stages of infertility treatment. MATERIALS...

Both respiratory syncytial virus (RSV) and influenza A virus induce nucleotide/P2Y purinergic receptor-mediated impairment of alveolar fluid clearance (AFC), which contributes to formation of lung edema. Although genetically dissimilar, both viruses generate double-stranded RNA replication intermediates, which act as Toll-like receptor (TLR)-3 ligands. We hypothesized that double-stranded RNA/T...
