Development of a quantitative fluorescence lateral flow immunoassay (LFIA) prototype for point-of-need detection of anti-Müllerian hormone.

Objective: Anti-Müllerian Hormone (AMH) is a quantitative marker for ovarian reserve and is used to predict response during ovarian stimulation. Streamlining testing to the clinic or even to the physician's office would reduce inconvenience, turnaround time, patient stress and potentially also the total cost of testing, allowing for more frequent monitoring. In this paper, AMH is used as a model biomarker to describe the rational development and optimization of sensitive, quantitative, clinic-based rapid diagnostic tests.

Reference ranges of anti-Müllerian hormone and interaction with placental biomarkers in early pregnancy: the Generation R Study, a population-based prospective cohort study.

Objective: The primary objective of this study is to establish maternal reference values of anti-Müllerian hormone (AMH) in a fertile multi-ethnic urban pregnant population and to evaluate the effect of gestational age. The secondary objective of this study is to explore the association between AMH and placental biomarkers.

Design: This study was embedded in the Generation R Study, an ongoing population-based prospective cohort study from early pregnancy onwards.

Effect of the glucagon-like peptide-1 analogue liraglutide versus placebo treatment on circulating proglucagon-derived peptides that mediate improvements in body weight, insulin secretion and action: A randomized controlled trial.

Aim: To examine how circulating glucagon-like peptide-1 (GLP-1) concentrations during liraglutide treatment relate to its therapeutic actions on glucose and weight, and to study the effects of liraglutide on other proglucagon-derived peptides (PGDPs), including endogenous GLP-1, glucagon-like peptide-2, glucagon, oxyntomodulin, glicentin and major proglucagon fragment, which also regulate metabolic and weight control.

Materials And Methods: Adults who were overweight/obese (body mass index 27-40 kg/m ) with prediabetes were randomized to liraglutide (1.8 mg/day) versus placebo for 14 weeks.

Inhibin A-A Promising Predictive Parameter for Determination of Final Oocyte Maturation in Ovarian Stimulation for IVF/ICSI.

The number of mature oocytes is a key factor in the success of Assisted Reproductive Techniques (ART). Exogenous gonadotropins are administered during ovarian stimulation in order to maximize the number of oocytes available for fertilization. During stimulation, monitoring is mandatory to evaluate individual response, to avoid treatment complications and assist in the determination of the optimal day for final oocyte maturation and oocyte retrieval.

Adjusting antimüllerian hormone levels for age and body mass index improves detection of polycystic ovary syndrome.

Objective: To examine whether accounting for a woman's age and body mass index (BMI) would improve the ability of antimüllerian hormone (AMH) to distinguish between women with (cases) and without (controls) polycystic ovarian syndrome (PCOS).

Design: An opportunistic case-control dataset of reproductive age women having evaluations for PCOS as defined by National Institutes of Health criteria.

Setting: Two medical centers in the United States enrolled women.

GLYCOSYLATED FIBRONECTIN AND INHIBIN ARE LOWER AND ANTI-MÜLLERIAN HORMONE IS HIGHER IN UMBILICAL CORD BLOOD WHEN MOTHERS HAVE PREECLAMPSIA.

Preeclampsia is a common disorder of pregnancy, causing significant morbidity and mortality for mothers and infants. Several molecules, including glycosylated fibronectin (GlyFn), the inhibin-related proteins, anti-müllerian hormone (AMH), and the insulin-like growth factor axis, are altered in maternal plasma in the setting of preeclampsia; however, these molecules have not been previously measured in cord blood of infants born to mothers with preeclampsia, which may represent changes in fetal physiology. We evaluated potential biomarkers of preeclampsia in umbilical cord blood to fill the gap in knowledge.

Placental proteases PAPP-A and PAPP-A2, the binding proteins they cleave (IGFBP-4 and -5), and IGF-I and IGF-II: Levels in umbilical cord blood and associations with birth weight and length.

Background: A newborn's birth weight for gestational age provides important insights into his or her fetal growth and well-being. While the underlying mechanisms regulating fetal growth remain to be fully elucidated, the IGF axis plays an important role. Some components of this axis have been well-characterized in umbilical cord blood, but others have not yet been studied.

The use of anti-Müllerian hormone as diagnostic for gonadectomy status in dogs.

In the veterinary practice, there is a need for a diagnostic tool to check the gonadal status in female dogs because it may be difficult to determine whether a female animal has been spayed or whether there are ovarian remnants. Although less prevalent, a similar situation pertains to male dogs. Anti-Müllerian hormone (AMH) is an important regulator of gonadal function and is a specific gonadal product that can be determined in circulation.

Increased antimüllerian hormone levels and other reproductive endocrine changes in adult male relatives of women with polycystic ovary syndrome.

Objective: To investigate for differences in reproductive hormone levels in male relatives of women with polycystic ovary syndrome (PCOS).

Design: Cross-sectional study.

Setting: Academic medical center.

Indirect targeting of IGF receptor signaling in vivo by substrate-selective inhibition of PAPP-A proteolytic activity.

The insulin-like growth factor (IGF) signaling pathway is involved in certain human cancers, and the feasibility of directly targeting the IGF receptor has been actively investigated. However, recent evidence from clinical trials suggests that this approach can be problematic. We have developed an alternative strategy to indirectly inhibit the IGF signaling by targeting the metalloproteinase, pregnancy-associated plasma protein-A (PAPP-A).

Altered regulation of insulin-like growth factor binding protein-1 in patients with polycystic ovary syndrome.

Objective: Insulin-like growth factor (IGF-I) action is influenced by circulating as well as tissue levels of its binding proteins. Because serum IGF binding protein-1 (IGFBP-1) levels have been found to be decreased in patients with polycystic ovary syndrome (PCOS), we tested the hypothesis that regulation of IGFBP-1 secretion may be different in patients with PCOS compared with normal women.

Methods: We studied 15 normal ovulatory women and 15 women with PCOS of similar age (21 +/- 1 and 22 +/- 1 years, respectively).
