The number of pituitary gonadotropin-releasing hormone receptors (GnRH-R) varies across the estrous cycle. We report that there is variable expression of the differently-sized GnRH-R transcripts in cyclic ewes and in an experimental model. During the follicular phase of the cycle, and compared to the luteal phase, there was increased expression of the 1.5, 2.3 and 3.7 kilobase (kb) transcripts with no change in the levels of the 5.6 or the 1.2 kb transcripts. Steady state levels of mRNA for luteinising hormone beta and common alpha subunit were also increased in the follicular phase of the cycle. In hypothalamo-pituitary disconnected ovariectomised ewes given pulsatile GnRH replacement, injection of estrogen increased the 1.5, 2.3 and 3.7 kb, while the levels of the 5.6 and 1.2 kb transcripts were not altered. We conclude that the differential regulation of GnRH-R mRNA occurs through a direct effect of E on the pituitary.

The complete Serine 8-type gonadotropin releasing hormone (GnRH) coding sequence with a substantial 5-prime regulatory sequence (5 kb) has been isolated and characterised in Nile Tilapia (Oreochromis niloticus) from a relevant genomic library. The primary structure of the protein precursor was identified for this gene. The promoter efficacy has been tested using 0.6 kb of the GnRH promoter driving a lacZ reporter gene in both cultured spleen cells and transiently expressing zebrafish. In the cell transfection experiments, the average level of beta-galactosidase activity in transfected cells was more than 2.1 (P<0.05) times higher than the control promoter-less vector in five independent cultures indicating that the 0.6 GnRH/lacZ construct is able to express in spleen cells. In addition, the transient expression of the lacZ gene was detected in the brain of G0 zebrafish embryos (Danio rerio) 4 days after fertilisation following egg injection with the construct, which demonstrated the efficacy of the tilapia GnRH promoter.

Osteoprogenitor cells present in human fetal bone marrow (BM) stroma have not been characterized. We used density gradient centrifugation, aggregation on binding lectin, and enrichment by magnetic activated cell sorting with STRO-1 antibody to isolate STRO-1+ cells from nonadherent human fetal BM stromal cells. Immunoselected STRO-1+ cells were immortalized using SV-40 large T antigen and a clone, F/STRO-1+ A, with weak alkaline phosphatase (ALP) activity was selected. The cloned cells proliferated rapidly but were not tumorigenic. Preconfluent F/STRO-1+ A cells showed immunoreactivity for osteopontin, alpha1(I) procollagen, and parathyroid hormone-related peptide, but not for the late osteoblast differentiation markers, osteocalcin (OC), or bone sialoprotein. However, differentiation of F/STRO-1+ A cells was induced by dexamethasone and 1,25-dihydroxyvitamin D3, as shown by increased ALP activity. In addition, osteogenesis occurred in F/STRO-1+ A cells cultured in three-dimentional aggregates, as assessed morphologically, histologically, and biochemically. Moreover, reverse transcription-polymerase chain reaction analysis showed that OC expression was silent in exponentially growing cells and occurred when cell-cell contacts were established in monolayer and in aggregates, showing induction of mature osteoblast phenotype by cell-cell contacts. Thus, clonal F/STRO-1+ A cells immunoselected from human fetal BM stroma display features of immature osteoprogenitor cells which can differentiate into mature osteogenic cells by cell-cell interactions or inducing agents. The generation by immunoselection of an immortalized clonogenic human fetal BM stroma-derived cell line which behaves like an osteoprogenitor cell provides a novel model system for identifying the signals required for the commitment of osteoprogenitors in the human fetal BM stroma.

Hemodialysis with high-calcium dialysate impairs cardiac relaxation.

BACKGROUND: During hemodialysis (HD), serum ionized calcium is directly related to the dialysate calcium concentration. We have recently shown an acute induction of hypercalcemia to impair left ventricular (LV) relaxation. In the current study we sought to establish whether changes in serum Ca++ also affect LV function during HD. METHODS: We echocardiographically examined the LV relaxation and systolic function of 12 patients with end-stage renal disease before and after three HD treatments with dialysate Ca++ concentrations of 1.25 mmol/liter (dCa++1.25), 1.5 mmol/liter (dCa++1.50), and 1.75 mmol/liter (dCa++1.75), respectively. Age- and sex-matched healthy controls were also examined echocardiographically. RESULTS: The LV posterior wall thickness and the interventricular septum thickness, and the LV end-diastolic dimension and the end-systolic dimensions were significantly greater in the patients when compared with the controls, and the LV fractional shortening, the ratio of peak early to peak late diastolic velocities (E/Amax), and the isovolumic relaxation time (IVRT) showed impairment of LV relaxation and systolic function in the patients. Serum ionized calcium increased significantly during the dCa++1.5 HD (1.24 +/- 0.10 vs. 1.34 +/- 0.06 mmol/liter, P = 0. 004) and dCa++1.75 HD (1.19 +/- 0.10 vs. 1.47 +/- 0.06 mmol/liter, P = 0.002), and plasma intact parathyroid hormone decreased significantly during the dCa++1.75 HD (medians 8.2 vs. 2.7 pmol/liter, P = 0.002). LV systolic function was not altered during any of the treatments. The changes in E/Amax and IVRT suggested impairment of relaxation during all sessions, but only during the dCa++1.75 HD was the impairment statistically significant (E/Amax 1. 153 +/- 0.437 vs. 0.943 +/- 0.352, P < 0.05; IVRT 147 +/- 29 vs. 175 +/- 50 msecond, P < 0.05). CONCLUSION: HD with high-calcium (dCa++1. 75 mmol/liter) dialysate impairs LV relaxation when compared with lower calcium dialysate (dCa++1.25 and dCa++1.5 mmol/liter) treatments.

Whole-cell patch-clamp recordings were made from CA1 pyramidal neurons of the rat hippocampus to study the modulation of gonadotropin-releasing hormone (GnRH) on synaptic transmission mediated by ionotropic glutamate receptors. Leuprolide (10(-9)-10(-7) M), a specific GnRH analog, concentration-dependently elicited a long-lasting potentiation of excitatory postsynaptic currents (EPSCs) mediated by ionotropic glutamate receptors. GnRH receptor-induced synaptic potentiation was blocked by 1 microM [Acetyl-3,4-dehydro-Pro1,D-p-F-Phe2,D-Trp3,6]-LHRH, a specific GnRH receptor antagonist. Furthermore, GnRH receptor-induced synaptic potentiation was associated with the stimulation of protein kinase C (PKC), being considerably attenuated by a potent PKC inhibitor (30 microM H-7). The results suggest a long-term enhanced modulation of GnRH on synaptic transmission mediated by ionotropic glutamate receptors, possibly via the actions of PKC in the hippocampus that is an important integrative system in the regulation of reproductive processes.

The most ostensive feature that distinguishes us human from chimps and other primates is the lack of bodily hair. During evolutionary process, we have lost the majority of hair. Hair is no longer an essential part of our body, just like appendix. What little hair we still have on our scalp and a few other bodily parts is still regarded as significant for reasons other than biological necessity. Hair loss is naturally accompanied by aging process, although the extent of hair loss and the timing of onset vary widely among individuals. Thus, loss of hair and baldness is considered as a symbol of maturity or old age. Like winkles and other signs of aging, hair loss is not welcome by most people, because we don't welcome aging, and being perceived as an aging person. However, it is alopecia, or premature hair loss that especially concerns certain people.
Hair Million is a blend of Asian herbs that wards off hair loss and promotes hair growth. Of various approaches to hair restoration, Hair Million offers advantages including low cost compared with other methods or drugs, and safety, because it is made of safe and healthy herbs.
