Age at first calving (AFC) affects the profitability of dairy enterprises. This study examined the relationships between AFC and subsequent fertility, milk production and survival up to third calving in UK Holstein-Friesian heifers; Study 1 comprised 134 consecutively born heifers from the same herd (AFC 764 ± 8 days) and Study 2 contained 445 heifers born on 17 farms (AFC 796 ± 6 days). Growth...

First published August 14, 2009; doi:10.1152/ajplung.00096.2009.—High tidal volume ventilation is detrimental to alveolar fluid clearance (AFC), but effects of ventilation pressure (P) on AFC are unknown. In anesthetized...

Effects of age at first calving (AFC) on functional longevity of Czech Holstein cows and their reproduction traits in the first lactation were analyzed using the first lactation data of 605 538 Holstein cows first calved from 1993 to 2008. Three classes were formed for AFC: low age class (16–24 months), average age class (25–30 months), and high age class (33–46 months). Effects of AFC on lengt...

BACKGROUND This study aimed to evaluate the strength of anti-Mullerian hormone (AMH) and follicle stimulating hormone (FSH) in reflecting the antral follicle count (AFC) in infertile females. MATERIALS AND METHODS This cross-sectional study was conducted on 160 females, visiting infertility clinic for assisted reproduction. Serum samples collected on the 3rd day of the cycle were assayed for ...

The rate of alveolar fluid clearance (AFC) is associated with mortality in clinical acute lung injury (ALI). Patients with ALI often develop circulatory shock, but how shock affects the rate of AFC is unknown. To determine the effect of circulatory shock on the rate of AFC in patients with ALI, the rate of net AFC was measured in 116 patients with ALI by serial sampling of pulmonary edema fluid...

BACKGROUND Antral follicle count (AFC) and anti-Mullerian hormone (AMH) are known as the most reliable markers of a woman's ovarian reserve and are related to age. There is currently no specific local age-related centile charts for AFC and AMH. Therefore, we aim to examine the relationship between AFC and AMH with age and construct age-related nomograms among a subfertile Asian population. ME...

BACKGROUND Life history models suggest that biological preparation for current versus longer term reproduction is favored in environments of adversity. In this context, we present a model of reproductive aging in which environmental adversity is proposed to increase the number of growing follicles at the cost of hastening the depletion of the ovarian reserve over time. We evaluated this model b...

Active Fiber Composites (AFC) manufactured at EMPA with commercially available piezoelectric ceramic fibers have been investigated for their potential use as Acoustic Emission (AE) sensors. AFC elements have been evaluated with methods derived from AE sensor characterization as well as additional measurements. Some commercial AE sensor types have been evaluated with the same methods for compari...

Am J Physiol Lung Cell Mol Physiol 282: L642–L649, 2002; 10.1152/ajplung.00417.2000.—We investigated the importance of changes in intracellular Ca2 concentration ([Ca2 ]i) for amiloride-sensitive alveolar fluid clearance (AFC) in late-gestational guinea pigs. Fetal guin...
