Effect of the menstrual cycle on circulation during combined spinal-epidural anaesthesia

tailieu.vn

The periodically fluctuating hormone levels affect the endometrium, causing the menstrual cycle to be divided into three phases: menstruation, the follicular and luteal phases. Re- cent studies have found that the heart rate is higher. during the luteal phase than during the follicular phase, while the heart rate varies less during the luteal phase than during the follicular phase.

Comparison of anterior knee laxity, stifness, genu recurvatum, and general joint laxity in the late follicular phase and the ovulatory phase of the menstrual cycle

tailieu.vn

In a previous study that examined vari- ations in GR and GJL during the menstrual cycle, GR was higher in the early luteal phase than in the early follicular phase [18]. Since Changes in E2 concentration during the menstrual cycle could affect neuromuscular control function [19], observation of changes in peripheral tissues only, excluding cen- tral nervous systems, is more appropriate to measure GR passively.

Expression characteristics of pineal miRNAs at ovine different reproductive stages and the identification of miRNAs targeting the AANAT gene

tailieu.vn

The target sites of miR- 89 (a) and miR-201 (b) in the 3 ’ UTR of the AANAT gene were predicted by RNAhybrid software. oocytes were higher in the follicular phase than in the luteal phase in rat ovaries [53], which is similar to the trend of AANAT variation in the pineal gland observed in this study.

During the luteal phase of the cycle, the corpus luteum is the dominant ovarian structure and the secretion of progesterone is critical to. Mechanisms controlling the function and life span of the corpus luteum. Selection of the dominant follicle in cattle. Length of the estrous cycle in both the sow and mare averages 19 22 days. [2] Estrous cycle of the mare and sow is characterized by four distinct stages called proestrus, estrus, metestrus, and diestrus.

Deciphering the oviductal extracellular vesicles content across the estrous cycle: Implications for the gametes-oviduct interactions and the environment of the potential embryo

tailieu.vn

Results: We identified the presence of oEVs, exosomes and microvesicles, in the bovine oviductal fluid at different stages of the estrous cycle (postovulatory-stage, early luteal phase, late luteal phase and pre-ovulatory stage) and demonstrated that their composition is under hormonal regulation. Major differences were found between post-ovulatory and the rest of the stages analyzed for mRNAs.

Ovarian cycle stage critically affects 21- gene recurrence scores in Mmtv-Pymt mouse mammary tumours

tailieu.vn

Tumours dissected from mice at diestrus, which is characterised by high concentrations of progesterone and an intermediate es- trogen concentration analogous to the luteal phase in humans, show a significant increase in 21-gene recurrence scores, compared to tumours collected at. Increased expression of Proliferation and HER2 group genes largely contributed to the increased 21-gene recurrence score observed in tumours collected at dies- trus.

Proven and unproven methods for diagnosis and treatment of infertility

tailieu.vn

In the clinical practice, the most common medical issues are: normal or disturbed ovarian function (e.g.. anovulation, oligoovulation, luteal phase defects), normal or abnormal anatomy of the oviducts and uterus, normal or disturbed spermato- genesis, endometriosis, but also a situation when all parameters are normal (un-explained infertility).. When the disturbed function of the ovaries is hypothesised then pharmacotherapy should be advised.

Genotype-by-environment interaction in Holstein heifer fertility traits using singlestep genomic reaction norm models

NR5A2 was mapped in C1, and it has been reported to affected ste- roidogenic pathways of progesterone production during the luteal phase of the estrous cycle in cattle [65].. The results indicated that EGFR could be involved in the regulation of the bovine oviductal microenvironment, but these regulatory mech- anisms may be compromised in the presence of heat stress. This indicates that the interaction between GUCY1B and HSP90 in cattle may be related to the heat stress response..

Ovary-derived circular RNAs profile analysis during the onset of puberty in gilts

Notably, for autophagy- animal pathway, “circ was ex- clusively expressed in the in-puberty, and its parental gene HIF1A has been reported to have the highest ex- pression in the early luteal phase [54]. In this study, we found that the AS events in circRNAs were consistent with previous reports, of which A3SS and ES events occurred in circRNAs in abundance.

Sows with H and L fertility were sacrificed at each of the two stages: on day 14 (day 1 = first day of estrus) after estrus in the luteal (L) phase (LH: n = 4. LL: n = 4) and on day 20 after estrus in the follicular (F) phase (FH:. The microRNA-Seq data is publicly available in the NCBI GEO database with the accession number GSE132307.. To explore the function of the miRNA, potential target genes of miRNAs with differential abundances were pre- dicted by miRanda [32].
