Segmental and Multifocal Isolated Dystonias: Similarities and Differences

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Whether the traditional distinction between segmental and multifocal dystonia is clinically or scientifically useful remains unclear. Objective To evaluate whether idiopathic isolated adult‐onset segmental and multifocal dystonia can be differentiated based on clinical features other than the contiguity of affected body regions ...

Bone Morphogenetic Protein-15 Inhibits Follicle-stimulating Hormone (FSH) Action by Suppressing FSH Receptor Expression [PDF]

Journal of Biological Chemistry, 2001
We have recently reported that oocyte-derived bone morphogenetic protein-15 (BMP-15) can directly modulate follicle-stimulating hormone (FSH) action in rat granulosa cells. Here, we investigate underlying mechanisms of this BMP-15 effect. Treatment with BMP-15 alone exerted no significant effect on the basal expression of mRNAs encoding steroidogenic ...

Multiple eumenorrheic cycles are necessary to observe a significant increase in estrogen exposure and ovulation in exercising women with functional hypothalamic oligo/amenorrhea undergoing a nutritional intervention: Insights from the REFUEL study

PM&R, EarlyView.
Abstract Background Due to consequences of energy‐related oligo‐/amenorrhea (Oligo/Amen) among exercising females, recovery of menses (ROM) is a priority. ROM is inconsistently defined and rarely reported with reproductive hormone (estrogen, progesterone) data, making it difficult to know when females achieve adequate recovery. Objective The purpose of

Engineering Immortalized Bovine Granulosa Cells Using a Triple-Gene Approach: Mutant CDK4, Cyclin D1, and TERT. [PDF]

Cell Biol Int
ABSTRACT Advancing reproductive technologies in livestock is essential to improve both productivity and genetic potential of cattle. Despite this importance, application of reproductive biotechnologies in cattle breeding remains limited. Bovine granulosa cells (bGCs), which are key components of the ovarian follicle, are critical in female reproduction

FSH Receptor Signaling: Complexity of Interactions and Signal Diversity [PDF]

Endocrinology, 2018
FSH is synthesized in the pituitary by gonadotrope cells. By binding to and interacting with its cognate receptor [FSH receptor (FSHR)] in the gonads, this gonadotropin plays a key role in the control of gonadal function and reproduction. Upon activation, the FSHR undergoes conformational changes leading to transduction of intracellular signals ...

Evaluation of Potential Hormonal Activities of Ashwagandha (Withania somnifera)

Phytotherapy Research, EarlyView.
ABSTRACT Ashwagandha is a widely used herb in traditional medicine systems, particularly Ayurveda. Despite its extensive tradition, growing concerns regarding its potential endocrinological effects have prompted scientific scrutiny. This review systematically evaluates the current preclinical, clinical, and case study evidence concerning AS's effects ...

Comparison of Sensitivity of FSH Levels and Vaginal pH in Diagnosis of Menopause, Estradiol Levels and Menopausal Signs

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2011
Introduction: As immunoassay and Eliza are used nowadays for checking levels of FSH and estradiol, the role of vaginal acidity as a sign of responding vaginal cells to estrogen has been forgotten, although its role in this field is known.
