To explore if the regulation at post-transcriptional level of follicular phase (Fols) to luteal phase (Luts) transition occurs in the ovaries of Anhuai goats, the differentially expressed microRNAs (miRNAs) of ovaries in the Fols and Luts were analyzed using Solexa sequencing in the study. In total, 320 known miRNAs were co-expressed in the two phases, 339 and 353 known miRNAs were expressed in...

This study determined effects of follicle stimulating hormone (FSH) alone and in combination with tumour necrosis factor (TNF), on granulosa cells from small (5-10 mm diameter) and large (>10-25 mm) follicles during follicular and luteal phases of the cycle and during periods of acyclicity. Granulosa cells were collected from ovaries of premenopausal women undergoing oophorectomy. The cells wer...

The aim of this study was to investigate whether the phases of the menstrual cycle affect lysine requirement in healthy adult females, as determined by the indicator amino acid oxidation (IAAO) method. Five healthy females with regular menstrual cycles were studied at seven graded levels of lysine intake, in random order, with an oral [13C]phenylalanine tracer protocol in both the follicular an...

The study was done to investigate the effects of cyclical changes of endogenous sex hormones during different phases of menstrual cycle on Acylation stimulating Protein (ASP) and its correlation with lipid profile parameters in healthy reproductive women. Twenty nine healthy reproductive women with regular menstrual cycles were included in this longitudinal study. The levels of FSH, LH, progest...

Variations in hormonal levels between the follicular and the luteal phase of the female menstrual cycle are associated with variations in emotional and cognitive aspects of behavior. The functional neural correlates of these cycle-related variations have been explored in previous neuroimaging studies. We summarize the existing findings of functional magnetic resonance imaging (fMRI) studies to ...

In adult females, previous work has demonstrated that changes in auditory function and vocal motor behaviors may accompany changes in gonadal steroids. Less is known, however, about the influence of gonadal steroids on auditory-motor integration for voice control in humans. The present event-related potential (ERP) study sought to examine the interaction between gonadal steroids and auditory fe...

BACKGROUND Alteration in physical work capacity of females during different phases of menstrual cycle has been reported in different populations. Pertinent data is unavailable in Eastern Indian population. OBJECTIVES The present study was aimed to determine the endurance capacity and cardiorespiratory responses during different phases of menstrual cycle in young sedentary females of Eastern r...

Single serum progesterone determinations were made in 79 apparently normal women with a regular menstrual cycle. A normal range (40 subjects) was derived from the concentrations in the follicular phase and used to define an "anovular" range for luteal phase values (nine out of 39 subjects). The remaining luteal phase values were used to construct an "ovular" range for the luteal phase and, with...

Gender differences in the incidence of many cardiovascular diseases may be due to the effects of sex hormones. Both alpha(1)- and alpha(2)-adrenergic receptors produce vasoconstriction in peripheral blood vessels and have demonstrated gender effects in previous studies. In addition, race has been shown to influence the effects of some alpha-adrenergic stimuli. We therefore sought to determine t...

This study assessed stressor and menstrual phase effects on psychophysiological and neuroendocrine responses to laboratory stressors in freely cycling women (N=78, ages 18-45). Participants performed counterbalanced stressors [Paced Auditory Serial Addition Test (PASAT) or cold pressor test (CP)] during their follicular and luteal menstrual cycle phases between 1:00 and 3:00p.m. to control for ...
