(n.) A genus of grasses, including a great number of species, as the kinds called meadow grass, Kentucky blue grass, June grass, and spear grass (which see).
Example Sentences:
(1) Gonadectomy has no effect on POA aromatase in the female.
(2) In addition, the warm-responsive neurones in the VMH region exhibited larger thermal coefficients than those in the POA region.
(3) Activity of the aromatase system in the POA, which converts testosterone to 17 beta-estradiol (E2), is increased by systemic androgen.
(4) In contrast, in the preoptic area-anterior hypothalamus (POA-AH) these antisera assayed amounts of LHRH that varied as a function of binding characteristics, although the quantities did not vary with the estradiol treatment schedule.
(5) Interleukin-1 alpha (IL-1 alpha) and interleukin-1 beta (IL-1 beta) are thought to be endogenous pyrogens, i.e., to mediate fever production; warm-sensitive (W) and cold-sensitive (C) neurons in the preoptic area (POA) are presumed to be the ultimate targets of endogenous pyrogens.
(6) One week after the placement of a lesion by radiofrequency or microinjection of kainic acid in the organum vasculosum of lamina terminalis (OVLT) but not in subfornical organ, ACTH response to intravenous IL-1 beta was enhanced, whereas both radiofrequency-induced lesion and kainic acid in the preoptic area (POA) suppressed the response.
(7) Pancreatic oncofetal antigen (POA) and carcinoembryonic antigen (CEA) were determined in plasma of 195 patients with breast cancer and 90 patients with colon carcinoma.
(8) These results show that damage to the AH or AH-POA junction in male marmosets causes a profound suppression of sexual 'arousal' and copulatory behaviour and that such affects are not due to androgen insufficiency or other, non-specific, side effects of neural damage.
(9) The threshold of AD and OD response in POA neurons declined during estrus and proestrus of the estrous cycle and in the Ovx-E group, but increased in the Ovx-P group and during diestrus.
(10) To determine if the median eminence itself could direct the growth of GnRH axons, co-grafts of POA and a fetal medial basal hypothalamic (MBH) block, which was predominantly median eminence, were made.
(11) These results indicate that the inductions of fever and plasma ceruloplasmin by IL6 are, like those of IL1, modulated in the POA, albeit the effective doses are much higher than those of IL1.
(12) Area POa in the lower bank is the recipient of a projection from the rostral inferior parietal lobule.
(13) Each neurotransmitter antagonist was administered via a chronically implanted steel guide tube into either the preoptic area (POA), retrochiasmatic area (RCh), or the median eminence region (ME).
(14) It is apparent from these studies that estrogen appears to activate the neurons of the POA receiving inhibitory synaptic input via the axonal collateral branches of the ARC neurons, and that progesterone seems to activate the neurons of the POA receiving excitatory synaptic input.
(15) In vitro estrogen formation was significantly lower in POA (p less than 0.05) and MBH (p less than 0.01) after castration.
(16) Custer I contained isolates from green healthy leaves of Agrostis tenuis, Festuca rubra, Holcus lanata, Lolium perenne and Poa pratensis, and clusters 2 and 3 consisted of isolates from Holcus lanata seeds and leaves of P. pratensis respectively.
(17) It was subsequently shown that males with a bilaterally lesioned SDN-POA still showed an increase in plasma testosterone.
(18) GnRH fibers projected from the medial POA to a dense fiber plexus in the median eminence (ME).
(19) The hypothalamic preoptic area (POA) was electrically stimulated through permanently implanted electrodes in 4 unanesthetized sheep.
(20) Coronal sections from midportions of the preoptic area (POA), suprachiasmatic nucleus (SCN) and arcuate nucleus (ARC) were examined by quantitative light microscopy in young (5 month) and old (18-20 months) intact mice and in old mice which had been ovariectomized at 6 months of age.
Poak
Definition:
(n.) Alt. of Poake
Example Sentences:
(1) I expect a very good game from England because they didn’t lose a point during qualification but I still have to say that there is a difference between the championship and qualifying.” This will be Slovakia’s first appearance at a European Championship and they got there in some style, beating Spain 2-1 at home en route to their finish as runners-up in qualifying Group C. Martin Skrtel and Marek Hamsik – the Liverpool centre-half and Napoli playmaker respectively – are their most recognisable names but much is expected of the Milan defensive midfielder Juraj Kucka and the POAK winger Robert Mak.
