The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Effect of growth hormone treatment on adult height of children with idiopathic short stature. Genentech Collaborative Group. (1/1891)

BACKGROUND: Short-term administration of growth hormone to children with idiopathic short stature results in increases in growth rate and standard-deviation scores for height. However, the effect of long-term growth hormone therapy on adult height in these children is unknown. METHODS: We studied 121 children with idiopathic short stature, all of whom had an initial height below the third percentile, low growth rates, and maximal stimulated serum concentrations of growth hormone of at least 10 microg per liter. The children were treated with growth hormone (0.3 mg per kilogram of body weight per week) for 2 to 10 years. Eighty of these children have reached adult height, with a bone age of at least 16 years in the boys and at least 14 years in the girls, and pubertal stage 4 or 5. The difference between the predicted adult height before treatment and achieved adult height was compared with the corresponding difference in three untreated normal or short-statured control groups. RESULTS: In the 80 children who have reached adult height, growth hormone treatment increased the mean standard-deviation score for height (number of standard deviations from the mean height for chronologic age) from -2.7 to -1.4. The mean (+/-SD) difference between predicted adult height before treatment and achieved adult height was +5.0+/-5.1 cm for boys and +5.9+/-5.2 cm for girls. The difference between predicted and achieved adult height among treated boys was 9.2 cm greater than the corresponding difference among untreated boys with initial standard-deviation scores of less than -2, and the difference among treated girls was 5.7 cm greater than the difference among untreated girls. CONCLUSION: Long-term administration of growth hormone to children with idiopathic short stature can increase adult height to a level above the predicted adult height and above the adult height of untreated historical control children.  (+info)

Perioperative growth hormone treatment and functional outcome after major abdominal surgery: a randomized, double-blind, controlled study. (2/1891)

OBJECTIVE: To evaluate short- and long-term effects of perioperative human growth hormone (hGH) treatment on physical performance and fatigue in younger patients undergoing a major abdominal operation in a normal postoperative regimen with oral nutrition. SUMMARY BACKGROUND DATA: Muscle wasting and functional impairment follow major abdominal surgery. METHODS: Twenty-four patients with ulcerative colitis undergoing ileoanal J-pouch surgery were randomized to hGH (12 IU/day) or placebo treatment from 2 days before to 7 days after surgery. Measurements were performed 2 days before and 10, 30, and 90 days after surgery. RESULTS: The total muscle strength of four limb muscle groups was reduced by 7.6% in the hGH group and by 17.1% in the placebo group at postoperative day 10 compared with baseline values. There was also a significant difference between treatment groups in total muscle strength at day 30, and at the 90-day follow-up total muscle strength was equal to baseline values in the hGH group, but still significantly 5.9% below in the placebo group. The work capacity decreased by approximately 20% at day 10 after surgery, with no significant difference between treatment groups. Both groups were equally fatigued at day 10 after surgery, but at day 30 and 90 the hGH patients were less fatigued than the placebo patients. During the treatment period, patients receiving hGH had reduced loss of limb lean tissue mass, and 3 months after surgery the hGH patients had regained more lean tissue mass than placebo patients. CONCLUSIONS: Perioperative hGH treatment of younger patients undergoing major abdominal surgery preserved limb lean tissue mass, increased postoperative muscular strength, and reduced long-term postoperative fatigue.  (+info)

Long-term effects of growth hormone (GH) on body fluid distribution in GH deficient adults: a four months double blind placebo controlled trial. (3/1891)

OBJECTIVE: Short-term growth hormone (GH) treatment normalises body fluid distribution in adult GH deficient patients, but the impact of long-term treatment on body fluid homeostasis has hitherto not been thoroughly examined in placebo controlled trials. To investigate if the water retaining effect of GH persists for a longer time we examined the impact of 4 months GH treatment on extracellular volume (ECV) and plasma volume (PV) in GH deficient adults. DESIGN: Twenty-four (18 male, 6 female) adult GH deficient patients aged 25-64 years were included and received either GH (n=11) or placebo (n=13) in a double blind parallel design. METHODS: Before and at the end of each 4 month period ECV and PV were assessed directly using 82Br- and 125I-albumin respectively, and blood samples were obtained. RESULTS: During GH treatment ECV increased significantly (before: 20.48+/-0.99 l, 4 months: 23.77+/-1.38 l (P<0.01)), but remained unchanged during placebo administration (before: 16.92+/-1.01 l, 4 months: 17.60+/-1.24 l (P=0.37)). The difference between the groups was significant (P<0.05). GH treatment also increased PV (before: 3.39+/-0.27 l. 4 months: 3.71+/-0.261 (P=0.01)), although an insignificant increase in the placebo treated patients (before: 2.81+/-0.18 l, 4 months: 2.89+/-0.20 l (P=0.37)) resulted in an insignificant treatment effect (P=0.07). Serum insulin-like growth factor-I increased significantly during GH treatment and was not affected by placebo treatment. Plasma renin (mIU/l) increased during GH administration (before: 14.73+/-2.16, 4 months: 26.00+/-6.22 (P=0.03)) and remained unchanged following placebo (before: 20.77+/-5.13, 4 months: 20.69+/-6.67 (P=0.99)) leaving no significant treatment effect (P=0.08). CONCLUSION: The long-term impact of GH treatment on body fluid distribution in adult GH deficient patients involves expansion of ECV and probably also PV. These data substantiate the role of GH as a regulator of fluid homeostasis in adult GH deficiency.  (+info)

Long-term results of GH therapy in GH-deficient children treated before 1 year of age. (4/1891)

OBJECTIVES: To evaluate the long-term effects of GH therapy in early diagnosed GH-deficient patients treated before 1 year of age. STUDY DESIGN: We studied all 59 patients (33 males) recorded by Association France-Hypophyse and treated with GH (0.50+/-0.15 IU/kg (S.D.) per week) before 1 year of age. Clinical presentation and growth parameters under GH treatment were analyzed. RESULTS: Neonatal manifestations of hypopituitarism were frequent: hypoglycemia (n=50), jaundice (n=25) and micropenis (n=17/33). Although birth length was moderately reduced (-0.9+/-1.4), growth retardation at diagnosis (5.8+/-3.8 months) was severe (-3.5+/-1.9 standard deviation scores (SDS)). Fifty patients (85%) had thyrotropin and/or corticotropin deficiency. After a mean duration of GH therapy of 8.0+/-3.6 years, change in height SDS was +3.11+/-2.06 S.D., exceeding 4 SDS in 19 patients. Only 9 patients (15%) did not reach a height of -2 S.D. for chronological age and 20 patients (34%) exceeded their target height. Pretreatment height SDS was independently associated with total catch-up growth. CONCLUSION: Conventional doses of GH allow normalization of height in patients with early GH deficiency and treatment.  (+info)

Changes in body composition and leptin levels during growth hormone (GH) treatment in short children with various GH secretory capacities. (5/1891)

OBJECTIVE: The aim of this study was to follow changes in body composition, estimated by dual-energy X-ray absorptiometry (DXA), in relation to changes in leptin during the first year of GH therapy in order to test the hypothesis that leptin is a metabolic signal involved in the regulation of GH secretion in children. DESIGN AND METHODS: In total, 33 prepubertal children were investigated. Their mean (S.D.) chronological age at the start of GH treatment was 11.5 (1.6) years, and their mean height was -2.33 (0.38) S.D. scores (SDS). GH was administered subcutaneously at a daily dose of 0.1 (n=26) or 0.2 (n=7) IU/kg body weight. Ten children were in the Swedish National Registry for children with GH deficiency, and twenty-three children were involved in trials of GH treatment for idiopathic short stature. Spontaneous 24-h GH secretion was studied in 32 of the children. In the 24-h GH profiles, the maximum level of GH was determined and the secretion rate estimated by deconvolution analysis (GHt). Serum leptin levels were measured at the start of GH treatment and after 10 and 30 days and 3, 6 and 12 months of treatment. Body composition measurements, by DXA, were performed at baseline and 12 months after the onset of GH treatment. RESULTS: After 12 months of GH treatment, mean height increased from -2.33 to -1.73 SDS and total body fat decreased significantly by 3.0 (3.3)%. Serum leptin levels were decreased significantly at all time points studied compared with baseline. There was a significant correlation between the change in total body fat and the change in serum leptin levels during the 12 months of GH treatment, whereas the leptin concentration per unit fat mass did not change. In a multiple stepwise linear regression analysis with 12 month change in leptin levels as the dependent variable, the percentage change in fat over 12 months, the baseline fat mass (%) of body mass and GHt accounted for 24.0%, 11.5% and 12.2% of the variability respectively. CONCLUSIONS: There are significant correlations between changes in leptin and fat and endogenous GH secretion in short children with various GH secretory capacities. Leptin may be the messenger by which the adipose tissue affects hypothalamic regulation of GH secretion.  (+info)

GH-binding protein in obese men with varying glucose tolerance: relationship to body fat distribution, insulin secretion and the GH-IGF-I axis. (6/1891)

Bioelectrical impedance for measurement of total body fat and computed tomography for visceral and subcutaneous fat at umbilicus levels were performed in 34 obese and 10 lean men. Insulin secretion in response to an oral glucose tolerance test (OGTT) and a GH stimulation test by L-dopa, growth hormone-binding protein (GHBP) and IGF-I were measured. Obese subjects were divided into three groups according to the OGTT. The obese type II diabetes mellitus group had the highest GHBP levels and the most visceral fat. GHBP levels were most strongly correlated with the ratio of visceral fat area to body weight (VWR) above any other parameters (r = 0.725, P<0.001). The insulin and free fatty acid (FFA) areas under curves (AUC) during the OGTT, and the IGF-I level, were also positively correlated with GHBP levels (r = 0.474, P<0.005; r = 0.572, P<0.005; r = 0.453. P<0.005). GH-AUC to the L-dopa stimulation test was negatively correlated with GHBP levels (r = -0.432. P<0.005). Stepwise multiple linear regression analysis showed that VWR, FFA-AUC and insulin-AUC significantly contributed to the variability of GHBP (r2 = 0.58). In conclusion, we demonstrated that: (i) visceral fat amount mainly determined GHBP levels in obese men with varying glucose tolerance: (ii) hyperglycemia per se did not influence the GHBP level, whereas insulin and FFA could play a role in regulation of GHBP: and (iii) although GH was not the main regulator of GHBP, the unchanged IGF-I level despite GH hyposecretion suggests that increased GHBP levels reflect GH hypersensitivity in order to compensate for decreased GH secretion in obesity.  (+info)

Apo E phenotype and changes in serum lipids in adult patients during growth hormone replacement. (7/1891)

OBJECTIVE: To determine whether apo E phenotype influences changes in lipid profiles induced by growth hormone replacement in growth hormone (GH)-deficient adults. DESIGNS: Patients were treated for 6 months with recombinant human GH (hGH), given in a dose of 0.125 U/kg per week for 4 weeks followed by 0.25 U/kg per week thereafter. The effects on serum lipids and the influence of apo E phenotype were examined. METHODS: Thirty patients (aged 35.1+/-11.8 years: mean +/- S.D.) with adult growth hormone deficiency with included in the study. Fasting serum samples were analysed for apo E phenotype total cholesterol, high-density lipoprotein (HDL)-cholesterol, triglycerides, lipoprotein (a) (Lp(a)) and IGF-I. Low-density lipoprotein (LDL)-cholesterol was calculated using the Friedwald formula. RESULTS: Six months of replacement treatment with hGH resulted in a reduction in HDL-cholesterol from 0.90+/-0.10 to 0.68+/-0.08 mmol/l (P<0.01), and a small, non-significant reduction in total cholesterol from 6.14+/-0.40 to 5.99+/-0.35 mmol/l (P = 0.06). There was no significant change in the other lipid parameters. The decrease in HDL-cholesterol concentration was greater in patients carrying the apo E2 allele (0.40+/-0.07 mmol/l, P<0.05) than in patients homozygous for the apo E3 allele (0.23+/-0.04 mmol/l) and patients carrying the apo E4 allele (0.15+/-0.36 mmol/l). Patients with the apo E4 allele had lower baseline cholesterol concentrations than patients lacking the apo E4 allele, and this persisted after treatment with hGH (P<0.05). CONCLUSIONS: Apo E phenotype may be a determining factor in the response of HDL-cholesterol to hGH in GH-deficient adults.  (+info)

Decreased hexosamine biosynthesis in GH-deficient dwarf rat muscle. reversal with GH, but not IGF-I, therapy. (8/1891)

Enhanced glucose flux via the hexosamine biosynthesis pathway (HNSP) has been implicated in insulin resistance. We measured L-glutamine:D-fructose-6-phosphate amidotransferase activity (GFAT, a rate-limiting enzyme) and concentrations of UDP-N-acetyl hexosamines (UDP-HexNAc, major products of HNSP) in muscle and liver of growth hormone (GH)-deficient male dwarf (dw) rats. All parameters measured, except body weight, were similar in 5-wk-old control and dw rats. Muscle GFAT activity declined progressively with age in controls and dw rats but was consistently 30-60% lower in 8- to 14-wk-old dw rats vs. age-matched controls; UDP-HexNAc concentrations in muscle were concomitantly 30% lower in dw rats vs. controls (P < 0.01). Concentrations of UDP-hexoses, GDP-mannose, and UDP in muscle were similar in control and dw rats. Muscle HNSP activity was similarly diminished in fed and fasted dw rats. In liver, only a small difference in GFAT activity was evident between controls and dw rats, and no differences in UDP-HexNAc concentrations were observed. Treatment with recombinant human GH (rhGH) for 5 days restored UDP-HexNAc to control levels in dw muscles (P < 0.01) and partially restored GFAT activity. Insulin-like growth factor I treatment was ineffective. We conclude that GH participates in HNSP regulation in muscle.  (+info)

Growth hormone deficiency (GHD) in adults arises as a consequence of decreased secretion of somatotropin (GH) from the anterior pituitary. The diagnosis of GHD is dependent on the demonstration of a subnormal rise in serum GH in response to one or more dynamic stimulation tests in the presence of co-existing pituitary disease or other pituitary hormone deficiencies. The syndrome of GHD is characterized by the variable presence of decreased exercise tolerance, decreased mood and decreased general well-being. These symptoms are associated with reduced bone remodelling activity, change in body fat distribution with increased central adiposity, hyperlipidaemia and increased predisposition to atherogenesis. Decreased psychological well-being and quality of life are recognised as particularly important and, from the patients perspective, have become arguably the major indication for GH replacement therapy.

He was not able to pull himself to standing position but after commencing growth hormone replacement, he demonstrated a dramatic improvement in his gross motor skills and was able to stand independently and walk with support.. A 4 year old boy with global developmental delay and was unable to stand independently. On investigation for short stature, he was noted to have isolated growth hormone deficiency and was commenced on growth hormone replacement. Three months later, he was noted to have made significant improvement in his muscle tone and general alertness. He was able to walk unaided for short distances.. A 10 year old boy with developmental delay and isolated growth hormone deficiency was commenced on growth hormone replacement at a small dose in January 2015. At his next neurology review ten ...
Because GH has a very short half life and is secreted in a pulsatile manner, mainly at night and after vigorous exercise, the measurement of a single growth hormone level is a useless exercise. The most stringent test for growth hormone deficiency is to measure growth hormone levels every 10 to 20 minutes in order to obtain an integrated 24-hour GH profile. As this is impractical outside the research setting, the recommended screening test for AGHD is the measurement of an IGF 1 level. The levels of IGF-1 (which has a half life of about 22 hours) are stable throughout the day with minimal diurnal variation and thus measurement of an IGF 1 level does not require the subject to be in fasting state. A low IGF-I level, age-adjusted, is a very specific indicator of AGHD. However its sensitivity is poor, especially in the setting of pituitary disease. In this situation there are often coexistent endocrine deficiencies as part of a syndrome of pan-hypopituitarism which provide initial diagnostic clues. ...

Hypothesis:. Pegvisomant combined with the glucagon stimulation test (GST) can improve the accuracy of this test when used to diagnose adult GH and cortisol (steroid hormone)insufficiency.. Study aims:. Diagnosing GH and cortisol deficiency in adults requires a special test. At present, the insulin tolerance test (ITT) is considered the test of choice. However, this test is difficult to perform as it involves giving insulin through the veins to decrease blood sugars to very low levels, and this can be unpleasant, and cannot be performed in elderly adults and in those with a history of heart disease, seizure disorders or stroke. For this reason there is an urgent need for an alternative reliable test. At present, the GST is considered the alternative test to the ITT but its accuracy in obese patients and in those with diabetes remains unclear. Pegvisomant is a medication that can increase GH production in the body. The purpose of this study is to find out if combining pegvisomant with the GST can ...

Growth hormone (GH) is used as a prescription biologic pharmaceutical to treat childrens growth disorders and adult growth hormone deficiency. Existing bioassays used in the manufacture and characterisation of growth hormone are expensive, tedious and require the sacrificing of rodents. Researchers at The University of Queensland (UQ) have developed an in vitro receptor-based cell proliferation assay for assessing the potency of human GH. The UQ cell line, designated BaFB2B2, expresses surface human GH receptors and proliferates in a dose dependent manner to human GH. From a manufacturing control perspective, this receptor-based method offers increased sample throughput and improved accuracy and precision compared with both the rat weight gain and tibial growth plate bioassays. The assay is highly specific for human GH and has been adopted by a number of biotech companies producing recombinant human GH.. ...

In addition, at the final examination the spouses completed a short questionnaire concerning their partner. Before treatment, the patients had lowered quality of life as determined by the HSCL and NHP inventories, and a correlation between the duration of GHD and the reported symptoms was observed. Upon treatment, the HSCL score was lower (better) after placebo administration (mean +/- SD, ...
Growth hormone (GH), also known as somatotropin (or as human growth hormone [hGH or HGH] in its human form), is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important in human development. It is a type of mitogen which is specific only to certain kinds of cells. Growth hormone is a 191-amino acid, single-chain polypeptide that is synthesized, stored and secreted by somatotropic cells within the lateral wings of the anterior pituitary gland. GH is a stress hormone that raises the concentration of glucose and free fatty acids. It also stimulates production of IGF-1. A recombinant form of hGH called somatropin (INN) is used as a prescription drug to treat childrens growth disorders and adult growth hormone deficiency. In the United States, it is only available legally from pharmacies, by prescription from a doctor. In recent years in the United States, some doctors have started to prescribe growth hormone in GH-deficient ...

OBJECTIVE: The objective was to investigate the effects of 3 years of growth hormone (GH) replacement therapy in GH deficient (GHD) patients in Sweden. DESIGN AND PATIENTS: An open label study in 237 adults with GHD (116 men and 121 women), consecutively enrolled in KIMS (Pfizers international metabolic database) in Sweden. MEASUREMENTS: QoL and healthcare consumption were determined using questionnaires [QoL-assessment of GHD in Adults (QoL-AGHDA), the psychological general well-being (PGWB) index and the patient life situation form (PLSF)]. RESULTS: The mean starting dose of GH was 0.13 mg/day and the mean maintenance dose was 0.37 mg/day. The mean insulin-like growth factor I (IGF-I) SD score increased from -1.92 at baseline to 0.38 after 3 years. There was a sustained increase in QoL as measured by the QoL-AGHDA and PGWB questionnaires. The number of doctor visits and the number of days in hospital were reduced after 3 years of GH replacement. The number of days of sickleave decreased during the
A growth hormone deficiency is caused due to disorders in the pituitary gland - the gland which is responsible for the production of growth hormone. What can cause the pituitary gland to become dysfunctional? Age, disease, head trauma, environmental pollution and sedentary lifestyle have all been shown to affect this delicate gland.. When the production of growth hormone by the pituitary gland reduces, linear growth in adults becomes slower than usual. While growth hormone is essential to stimulate regular growth in children, it is vital for the maintenance of the right bone, muscle, and body fat levels in adults. Low levels of growth hormone can lead to emotional disturbances poor motivation and tiredness. Cholesterol levels in an individual can also be negatively affected by a growth hormone deficiency.. There is no particular age when the deficiency of growth hormone may arise in adults. A large number of individuals do not even realize that they are living with Adult Growth Hormone ...

Human Growth Hormone is produced in the body by the pituitary gland. Before this happens, Growth Hormone Releasing Hormone (Human Growth Hormone RH) and Somatostatin (SST) are released by the hypothalamus, and that determines whether more or less Human Growth Hormone is produced by the pituitary.(1) Many factors influence the release of Human Growth Hormone, however, including nutrition and exercise (6)(7). Once it is released, Human Growth Hormone (Human Growth Hormone), which is also called Human Growth Hormone (STH) has many functions in the human body. Human Growth Hormone is a protein that stimulates the body cells to increase both in size, as well as undergo more rapid cell division than usual. In addition, it enhances the movement of amino acids through cell membranes and also increases the rate at which these cells convert these molecules into proteins. Clearly, you can see that this would amount to an anabolic (muscle building) effect in the human body. Human Growth Hormone also has the ...

Growth hormone deficiency (GHD) is a medical condition due to not enough growth hormone (GH). Generally the most noticeable symptom is a short height. In newborns there may be low blood sugar or a small penis. In adults there may be decreased muscle mass, high cholesterol levels, or poor bone density. GHD can be present at birth or develop later in life. Causes may include genetics, trauma, infections, tumors, or radiation therapy. Genes that may be involved include GH1, GHRHR, or BTK. In a third of cases no cause is apparent. The underlying mechanism generally involves problems with the pituitary gland. Some cases are associated with a lack of other pituitary hormones, in which case it is known as combined pituitary hormone deficiency. Diagnosis involves blood tests to measure growth hormone levels. Treatment is by growth hormone replacement. The frequency of the condition is unclear. Most cases are initially noticed in children. The genetic forms are estimates to affect about 1 in 7,000 ...

article{01b731d3-c588-4a6e-b4b4-f23036b68aea, abstract = {Objective: GH and IGFs have mitogenic properties, causing speculation that GH treatment could increase risk of malignancy. While studies in GH-treated childhood cancer survivors have suggested a slight increase in second neoplasms, studies in GH-treated adults have been equivocal. Design: Incidence of de novo and second cancers was evaluated in 6840 GH-treated and 940 non GH-treated adult patients in the Hypopituitary Control and Complications Study pharmacoepidemiological database. Methods: Evident cancer cases were evaluated in the main analysis, with sensitivity analyses including probable and possible cancers. Standardized incidence ratios (SIRs) for cancers were calculated using Surveillance, Epidemiology and End Results for the USA and GLOBOCAN for all other countries. Results: During the mean follow-up of 3.7 years/GH-treated patient, 142 evident cancer cases were identified, giving an overall SIR of 0.88 (95% confidence interval ...
Patients with Prader-Willi syndrome (PWS) have a cognitive impairment. Growth hormone (GH) treatment during childhood improves cognitive functioning, while cognition deteriorates in GH-untreated children with PWS. Cessation of GH treatment at attainment of adult height (AH) might deteriorate their GH-induced improved cognition, while continuation might benefit them. We, therefore, investigated the effects of placebo versus GH administration on cognition in young adults with PWS who were GH-treated for many years during childhood and had attained AH. Two-year, randomized, double-blind, placebo-controlled cross-over study in 25 young adults with PWS. Cross-over intervention with placebo and GH (0.67 mg/m2/day), both during 1 year. Total (TIQ), verbal (VIQ) and performance IQ (PIQ) did not deteriorate during 1 year of placebo, compared to GH treatment (p | 0.322). Young adults with a lower TIQ had significantly more loss of TIQ points during placebo versus GH, in particular VIQ decreased more in those with

The electrospray mass spectra of several standard proteins were recorded and their molecular weights determined. These were compared to Literature values obtained by other laboratories. The agreement was quite good. Seven recombinant growth hormones were then investigated by this technique. The determined molecular weights were in agreement with the theoretical values. Differentiation between six of the seven analogs could be made on the basis of the molecular weight determinations. Two of these analogs differed in molecular weight by only 1 Da and the accuracy of the mass measurements was not sufficient for distinguishing these two homologous proteins. The influence of solvent on the mass accuracy determinations was studied. It appears that solvents form clusters with the proteins in the electrospray ionization method. These clusters broaden the peaks corresponding to the multiply charged ions of the proteins and make the detemination of centroids more difficult. ...

Human growth hormone (or HGH) is a member of a family of endocrine hormones. This family includes hormones such as testosterone, estrogen, melatonin and DHEA. Production of HGH and other hormones decreases with age. While all these hormones have anti-aging effects, only HGH go far beyond the reach of other hormones to prevent biological aging and also revert to a wide range of aging symptoms and even some aging diseases. HGH is known to be the most abundant endocrine hormone produced by the pituitary gland. Growth hormone is secreted at a rate that reaches a maximum during the mid-twenties, when a young person develops. The decline in the production of human growth hormone is directly associated with some signs of aging such as wrinkles , hair aging , decreased energy and sex, erectile dysfunction in men and menopause in men Women, an increase in body fat, heart disease and blood pressure problems, fragile and brittle bones and much more. Although HGH cannot completely stop the aging process, ...

1. Using a highly specific radioimmunoassay we have measured immunoreactive human growth hormone releasing factor (ir-hGRF) concentrations in the peripheral circulation of a total of 12 normal subjects.. 2. Neither insulin-induced hypoglycaemia, intravenous arginine nor oral carbohydrate caused any change in venous plasma ir-hGRF concentrations, despite the expected stimulation and suppression respectively of growth hormone secretion.. 3. Growth hormone secretion was not increased by oral fat or protein but each of these two foods stimulated ir-hGRF concentrations two- to fourfold.. 4. Spontaneous pulses of growth hormone secretion on control days were unaccompanied by any increase in plasma ir-hGRF.. 5. The dissociation between peripheral circulating ir-hGRF and growth hormone responses demonstrated under different circumstances suggests that an important source of human growth hormone releasing factor lies outside the hypothalamus and that secretion from this source is unconnected with the ...
The main aim of the thesis was to explore the potential of supercritical fluid (SF) techniques in the field of drug delivery. In particular, the relatively recently developed solution-enhanced dispersion by supercritical fluids (SEDS) technology has been employed in the preparation of particles/powders. The manufacturing, stability and bioavailability of a dosage form strongly depend on the physicochemical properties of the formulation particles. For example, dry powder inhalation (DPI) for administering drugs to the respiratory tract require particles in a narrow size range (1-5 μm) to be effective. The identification of polymorphs and control of purity are also important issues since the physicochemical properties and therapeutic effects of the alternative forms of a drug may differ substantially. Solvent-based traditional crystallisation processes provide the product that may require further down-stream processing to obtain particles for advanced drug delivery applications. This can result ...
