The role of progesterone (P4) in the regulation of inflammatory mediators interleukin-8 (IL-8), monocyte chemoattractant protein-1, and cyclooxygenase-2 (COX-2) and in the recruitment of leukocyte subpopulations in the endometrium has been examined, by employing a model of P4 withdrawal and maintenance in vivo. Messenger RNA and protein expression have been investigated in endometrial biopsies:...

the aim of this study was to evaluate the effect of replacing progesterone injections by progesterone vaginal inserts on productive and reproductive parameters of lactating cows with reproductive problems after prolonged periods of heat stress. fifteen holstein cows were randomly assigned to one of three treatments: 1) treated with two progesterone vaginal inserts (p4-ins); 2) treated with prog...

The objectives in this study were to determine whether treatment with progesterone (P4) via an intravaginal device would induce estrus and development of corpora lutea (CL) with typical life spans and whether treatment with estradiol benzoate (EB) following device removal would enhance the responses. At treatment initiation (d 0), suckled beef cows (n = 362) that were anestrous received one of ...

Traumatic brain injury (TBI) is an important and costly medical problem for which no clinically proven treatment currently exists. Studies in rodents and humans have shown beneficial effects of progesterone (P4) on both mortality and functional outcomes following TBI. Neuroprotective effects of P4 in TBI likely involve the classical nuclear progesterone receptors (Pgr) that are widely distribut...

The objective was to investigate effects of progesterone (P4) dose on abundance luteinizing hormone receptor (LHCGR), aromatase (CYP19A1), 3β-hydroxysteroid dehydrogenase (HSD3B1), and other steroidogenic mRNA transcripts in granulosa cells from dominant follicles. Nellore heifers were assigned one six groups: new, first-use controlled internal drug release device (CIDR1) inserted for 5 days (L...

Hippocrates was the first to raise awareness of medicine as a science. He asserted the body being a unified whole and emphasized the importance of preventive and predictive medicine, spurring physicians to foster patient collaboration. Recent achievements today have permitted a new approach "P4 medicine" - Predictive, Preventive, Personalized and Participatory - with the aim of depicting an ind...

Systems biology and the digital revolution are together transforming healthcare to a proactive P4 medicine that is predictive, preventive, personalized and participatory. Systems biology - holistic, global and integrative in approach - has given rise to systems medicine, a systems approach to health and disease. Systems medicine promises to (1) provide deep insights into disease mechanisms, (2)...
