Role of ultrasound and color Doppler in diagnosis of ectopic pregnancy and to differentiate from corpus luteum cyst of pregnancy

open access: yesAsian Journal of Medical Sciences
Background: Ectopic pregnancy is the leading cause of direct maternal deaths. Ectopic pregnancy and corpus luteum cyst are two most common differential diagnoses in a patient with urine pregnancy test (UPT) positive and no sonographic evidence of ...

Quantification of steroid hormones in free‐ranging Apennine wolf Canis lupus italicus hair samples collected post‐mortem

open access: yesWildlife Biology, EarlyView.
After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

Matrix Metalloproteinase 2 Is Required for Ovulation and Corpus Luteum Formation in Drosophila

open access: yesPLoS Genetics, 2015
Ovulation is critical for successful reproduction and correlates with ovarian cancer risk, yet genetic studies of ovulation have been limited. It has long been thought that the mechanism controlling ovulation is highly divergent due to speciation and ...

Society for Endocrinology Clinical Practice Guideline for the Evaluation of Androgen Excess in Women

open access: yesClinical Endocrinology, EarlyView.
ABSTRACT Context Androgen excess is common in women and refers to clinical or biochemical evidence of elevated androgenic steroids such as testosterone. It is associated with underlying polycystic ovary syndrome in the majority of cases. However severe androgen excess is less common and may indicate the presence of underlying adrenal or ovarian ...

Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss

open access: yesEquine Veterinary Journal, EarlyView.
Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.

Can luteal regression be reversed?

open access: yesReproductive Biology and Endocrinology, 2006
The corpus luteum is an endocrine gland whose limited lifespan is hormonally programmed. This debate article summarizes findings of our research group that challenge the principle that the end of function of the corpus luteum or luteal regression, once ...

Emerging roles for integrated stress response signaling in homeostasis

open access: yesThe FEBS Journal, EarlyView.
Integrated stress response (ISR), an evolutionarily conserved eukaryotic stress‐adaptive program in eukaryotes, has also been implicated in homeostatic functions. This review covers a broad body of literature and presents several homeostatic functions of ISR in the absence of stress: (a) developmental processes (morphogenesis, differentiation, aging), (

The lncRNA Neat1 is required for corpus luteum formation and the establishment of pregnancy in a subpopulation of mice

open access: yesDevelopment, 2014
Neat1 is a non-protein-coding RNA that serves as an architectural component of the nuclear bodies known as paraspeckles. Although cell-based studies indicate that Neat1 is a crucial regulator of gene expression, its physiological relevance remains ...
