Introduction
There is still controversy regarding the exercise characteristics that are more effective for improving peak oxygen uptake (VO2 peak), cardiac and metabolic function. High- intensity interval exercise training (HIIT) has been shown to elicit comparable and/or superior performance on endurance capacity (EC), ventricular function (VF) and quality of life. By other side, there is robust evidence that combined endurance and strength training is significantly more effective than endurance training only for improving EC, muscle mass and muscle strength.
There is no enough information if the combination of HIIT with high strength training (HST) could enhance the physical conditions of these patients.
Purpose
The purpose of our study was to analyze the combination of HIIT + HST and its effect on physical performance compared to different types of combined training: HIIT and MCT with low load resistance training (RT) and HIIT or MCT only.
Methods
We evaluated 140 male patients (p) with CAD documented by angiographic studies, clinically stables with medical treatment and sinus rhythm.
All of them performed a stress testing in treadmill without handrail support using a ramp protocol until maximal effort. VO2 peak (ml/kg/min) was measured indirectly through ACSM formula. We used YMCA´s method of estimating body fat with measurement of skinfolds in four sites (BF %), 30-second chair stand test (CST), 8-foot up and go test (FUGT), six-minute walk test (T6min) and one maximum repetition for quadriceps extension (1RMq) .Training intervention: p were randomly allocated to HIIT + RT (n=30), MCT + RT (n=30), HIIT (n=30), MCT (n=30) and HIIT + HST (n=20) during 3 month period of training.
HIIT: 4 x 4 (85-95% peak heart rate) and 60-70% during active breaks. (36 min)
MCT: 70-75% peak heart rate.(36 min)
RT: 40-50% 1RM for lower body with 12-15 repetitions in 2 sets
HST: ≥ 70% 1RM for lower body with low number of repetitions.
Statistical analysis: all data were analyzed using IBM SPSS V.24. Comparisons were performed by following one-way ANOVA(parametric distribution) with post-hoc Tuckey or Kruskal-Wallis(non parametric distribution). The level of statistical significance was P< 0.05.
Results
Analyzing values pretraining (PRE) vs. postraining (POST), VO2 peak increased significantly by 27,52% for HIIT + HST P< 0,03 vs. HIIT + RT- MCT + RT and MCT. A positive effect in HIIT + HST with FUGT P< 0,001 and CST P< 0,005 between group changes and favourable observations in relation to 1RMq (PRE 60,00 ± 9,07 vs. POST 73,00 ± 9,86) and %BF(PRE 26,60 ± 3,21 vs. POST 24,80 ± 3,72) compared to MCT and HIIT P < 0,05. We didn´t find statistical significant differences with both modalities of combined training (low workloads) and HIIT for T6min.
Conclusions
High intensity combined training (HIIT + HST) had an additional effect related to others aerobic and resistance exercises attributed to neuromuscular adaptations, increased power and muscle strength.

Abstract
The false fruits of apple (Malus domestica) and pear (Pyrus communis) are consumed all over the world, contributing to the dietary intake of health-promoting antioxidant phytochemicals. For example, polyphenols confer many beneficial effects (according to their chemical structure, bioavailability, and absorption efficiency in the gut) and the consumption of polyphenol-rich apple and pear fruits may therefore reduce the risk of some diseases. However, the content of such molecules is highly dependent on the specific fruit cultivar. To examine this metabolic diversity in detail, we used metabolomic analysis (NMR and HPLC-DAD/MS) to profile the metabolome of six apple and five pear cultivars. We also determined the antioxidant capacity of the extracts (FRAP assay) and correlated this with the metabolomic composition and abundance of specific metabolites. We observed the cultivar-specific accumulation of sugars, amino acids, malic acid, and various polyphenols, which was also related to the growing season for some cultivars. We found that the ancient Italian apple Pom Prussian was enriched for chlorogenic acid as well as more characteristic polyphenols (phloretin derivatives), the pear cultivar Abate Fetel was low in sucrose, and both cultivars displayed high in vitro antioxidant activity. These cultivars may, therefore, be particularly attractive to health-conscious consumers.

Abstract
Plant biomasses growing in bioreactor could be developed as production systems for cosmetic ingredients, nutraceuticals and food additives. We previously reported that the red carrot cell line R4G accumulates high levels of anthocyanins, which are potent antioxidants with multiple health-promoting properties. To investigate the industrial potential of this cell line in detail, we tested extract for antioxidant and anti-inflammatory activity in the mouse monocyte/macrophage cell-line J774A.1 and in reconstructed skin tissue models. We also compared the R4G extract to commercial carrot extracts in terms of stability and metabolomic profiles. We found that the R4G extract have potent antioxidant and anti-inflammatory activities, protecting mammalian cells from the oxidative stress triggered by exposure to bacterial lipopolysaccharides and H2O2. The extract also inhibited the nuclear translocation of NF-κB in an epidermal skin model, and induced the expression of VEGF-A to promote the microcirculation in a dermal microtissue model. The anthocyanins extracted from R4G cells were significantly more stable than those found in natural red carrot extracts. Finally, we showed that R4G extract has similar metabolomic profile of natural extracts by using a combination of targeted and untargeted metabolomics analysis, demonstrating the safety of R4G carrot cells for applications in the nutraceutical and food/feed industries.

Abstract
Kiwifruit (Actinidia deliciosa cv. Hayward) is a commercially important crop with highly nutritional green fleshy fruits. The post-harvest maturation of the fruits is well characterized, but little is known about the metabolic changes that occur during fruit development. Here we used untargeted metabolomics to characterize the non-volatile metabolite profile of kiwifruits collected at different time points after anthesis, revealing profound metabolic changes before the onset of ripening including the depletion of many classes of phenolic compounds. In contrast, the phytohormone abscisic acid accumulated during development and ripening, along with two indolamines (serotonin and its precursor tryptamine), and these were monitored in greater detail by targeted metabolomics. The role of indolamines in kiwifruit development is completely unknown, so we also characterized the identity of genes encoding tryptophan decarboxylase in A. deliciosa and its close relative A. chinensis to provide insight into the corresponding biological processes. Our results indicate that abscisic acid and indolamines fulfill unrecognized functions in the development and ripening of kiwifruits.

Abstract
Fruits stored at low temperature can exhibit different types of chilling injury. In apple, one of the most serious physiological disorders is superficial scald, which is characterized by discoloration and brown necrotic patches on the fruit exocarp. Although this phenomenon is widely ascribed to the oxidation of α-farnesene, its physiology is not yet fully understood. To elucidate the mechanism of superficial scald development and possible means of prevention, we performed an integrated metabolite screen, including an analysis of volatiles, phenols and lipids, together with a large-scale transcriptome study. We also determined that prevention of superficial scald, through the use of an ethylene action inhibitor, is associated with the triggering of cold acclimation-related processes. Specifically, the inhibition of ethylene perception stimulated the production of antioxidant compounds to scavenge reactive oxygen species, the synthesis of fatty acids to stabilize plastid and vacuole membranes against cold temperature, and the accumulation of the sorbitol, which can act as a cryoprotectant. The pattern of sorbitol accumulation was consistent with the expression profile of a sorbitol 6-phosphate dehydrogenase, MdS6PDH, the overexpression of which in transgenic Arabidopsis thaliana plants confirmed its involvement in the cold acclimation and freezing tolerance.

Abstract
Fruits of the sweet cherry (Prunus avium L.) accumulate a range of antioxidants that can help to prevent cardiovascular disease, inflammation and cancer. We tested the in vitro antioxidant activity of 18 sweet cherry cultivars collected from 12 farms in the protected geographical indication region of Marostica (Vicenza, Italy) during two growing seasons. Multiple targeted and untargeted metabolomics approaches (NMR, LC-MS, HPLC-DAD, HPLC-UV) as well as artificial simplified phytocomplexes representing the cultivars Sandra Tardiva, Sandra and Grace Star were then used to determine whether the total antioxidant activity reflected the additive effects of each compound or resulted from synergistic interactions. We found that the composition of each cultivar depended more on genetic variability than environmental factors. Furthermore, phenolic compounds were the principal source of antioxidant activity and experiments with artificial simplified phytocomplexes indicated strong synergy between the anthocyanins and quercetins/ascorbic acid specifically in the cultivar Sandra Tardiva. Our data therefore indicate that the total antioxidant activity of sweet cherry fruits may originate from cultivar-dependent interactions among different classes of metabolite.

Abstract
In recent years, the treatment of metastatic colorectal cancer (mCRC) has evolved significantly with the increase of new therapeutic options, leading to an improved median survival for these patients. In particular, the identification of molecular targets in tumor cells has led to the introduction of biological drugs for the treatment of mCRC. Panitumumab is a fully human monoclonal antibody that binds the EGF receptor of tumor cells and inhibits downstream cell signaling with antitumor effect on inhibition of tumor growth. Its use has been approved by randomized clinical trials as monotherapy in chemorefractory patients or combined with chemotherapy in the treatment of RAS wild-type mCRC, where it demonstrated a significant improvement in survival and response rate. The purpose of this review is to analyze the use and efficacy profile of panitumumab, particularly focusing on recently reported data on its use, and future perspectives in patients with mCRC.

Abstract
Purpose Evidences have shown that neutrophil-to-lymphocyte ratio (NLR) has a prognostic value in patients with cancer. We wanted to test the prognostic significance of NLR in prostatic cancer of patients who are candidate to radical prostatectomy. Methods We have considered 731 patients. Complete demographic data including age, tumor stage, Gleason score, complete blood count and serum biochemical profile were collected. Pre-treatment percentage of neutrophils and NLR were considered, and correlated with patients data and recurrence free survival. Results 389 patients were evaluated, mean age 65 years, mean follow-up 51.5 months, mean recurrence free survival 51.3 months. Total neutrophil count does not correlate with biochemical recurrence and disease free survival. Patients with a value higher of 60% of neutrophils are more likely to have a recurrence. Patients with a total lymphocyte count <1,500 have a higher rate of relapse. NLR was not correlated with baseline total PSA, with Gleason score and with pathological stage; patients with a NLR >3 has a higher incidence of recurrence. In multivariate analysis including age, total PSA and NLR, NLR is the most important factor able to predict recurrence. There are some limitations to this study; first, this is a retrospective study, and the total number of patients analyzed is relatively small. Conclusions Our study suggests that pre-treatment NLR may be associated with disease free survival in patients with prostate cancer, and could be introduced in clinical practice. NLR has the advantage of low economic cost and wide availability.

Abstract
The refractive indexes, material attenuation and damage fractions of a multi-step ion implanted Lithium Niobate (LiNbO3) waveguide were analyzed as functions of the annealing temperatures. An almost flat damage depth profile was designed to reduce the uncertainties related to the indexes profile shape, thus providing a better test-case for the characterizations. The measurements performed on the fabricated optical waveguides confirmed the predicted step-index profiles showing that the light is confined inside the damaged layer. The low measured attenuation (less than 0.8 dB/cm @ 632.8 nm) makes the obtained waveguide attractive for device fabrication.

Abstract
BACKGROUND Although most patients at high risk of Gestational Trophoblastic Neoplasia (GTN) respond to standard treatments, there is a group of patients that will die because of it. The use of new single or combination drugs in this population has become a priority. CASE REPORT We present the case of a relapsed high risk choriocarcinoma patient who did not respond to several chemotherapy treatments nor to PET guided salvage surgery. Because of treatment toxicity, the patient was started on Capecitabine, with which she achieved total remission, still present after 15 months of starting treatment. CONCLUSIONS The use of Capecitabine and the multidisciplinary management of this population should be taken into account for patients at high risk of relapsing to EP/EMA because of its efficacy and little toxicity.

Abstract
21183 Background: Statistical report which considers the discharge of oncology patients from thirteen acute general Hospitals from the CBAG in order to determine how to allocate founds and propose epidemilogy, preventive and/or therapeutics trials. Methods: Review of the information given by the HSD of the CBAG Ministry.The variables taken into account were: type of cancer (CIE-10-OMS), sex, age and area of residency. Results: During 2005, in the 13 acute care hospitals of CBAG there were 132,431 disc; among these 6,896 were oncology patients (5%). From the total number of hospital beds used that year (1,074,495), 90,352 were oncology patients (9%). The malignant tumor diagnosis were; Gynecologic 23% (cervix 689 + in situ 134, ovarian 479, uterine 120 and other 188); digestive 15% (colorectal 529, pancreatic 149, stomach 134, esophagus 188 and others 34); hematologic 15% (lymphomas 500, leukemias 410, myelomas 77 and others 46); breast 12% (849); lung 10% (681); urologic 9% (bladder 228, prostate 187, kidney 115, testicle 43 and others 22); miscellaneus 15% (1,065). Sex: Female (F) discharges were 4,158 and male (M) 2,738; the relationshionship F/M was 1.5/1. The group mean age was 56.1± 16.6 years. Area of residence: 53% belonged to the City of Buenos Aires and 40 % to suburban areas. Conclusions: The diagnosis of the pathologies found could help determine epidemiology and therapeutic trials. Hospitalizacions due to cancers that can be ‘prevented by screening‘, such as breast, cervical and colon cancer, support the need to redefine prevention campaigns. No significant financial relationships to disclose.

Abstract
Absorption or emission spectroscopy is a powerful tool for detecting chemical compounds, diluted in fluid media: the sensitivity of this technique depends on the optical path of the source radiation, on the spectral window used for analysis and on the spectrometer performances. In this view, we designed and produced the first prototypes of an integrated scanning Fourier Transform Microinterferometer with Mach-Zehnder geometry, by using MEOS (Micro Electro Optical Systems) technologies. The microdevice, obtained by fabricating integrated optical waveguides on LiNbO(3) (LN) crystals, is electrically driven, without moving parts, by exploiting the electrooptical properties of the material. The microdevice operates the Fourier Transform of the input radiation spectral distribution, which can be reconstructed starting from the output signal by means of Fast Fourier Transform (FFT) techniques. The microinterferometer weights few grams, the power consumption is of a few mW and, in principle, can operate in the LN transmittance range (0.36-4.5 microm). The microinterferometer performances were preliminary tested in the (0.4-1.7 microm) spectral window. In the Visible region (0.4-0.7 mum) this microsystem demonstrated a spectral resolution suitable for detecting the characteristic lines of the solar spectrum together with the absorption bands of common gases present in Earth's atmosphere. In a further experiment we tested its performances for gas trace detection by using a calibrated NO(2) optical gas cell, showing the possibility to reveal up to 10 ppb, when suitable optical paths are used. Finally, colorimetry tests for the titration of an organic dye (E131) in alcohol solution are presented.

Abstract
BACKGROUND As continuous wound instillation with local anaesthetic has not been evaluated after hip/knee arthroplasties, our study was designed to determine whether this technique could enhance analgesia and improve patient outcome after joint replacement surgery. METHODS Thirty-seven patients undergoing elective hip/knee arthroplasties under spinal block were randomly assigned to two analgesia groups. Group M received continuous i.v. infusion of morphine plus ketorolac for 24 h. Then, a multi-hole 16 G catheter was placed subcutaneously and infusion of saline was maintained for 55 h. Group R received i.v. saline. Thereafter the wound was infiltrated with a solution of ropivacaine 0.5% 40 ml, then a multi-hole 16 G catheter was placed subcutaneously and an infusion of ropivacaine 0.2% 5 ml h(-1) was maintained for 55 h. Visual analogue scale scores were assessed at rest and on passive mobilization by nurses blinded to analgesic treatment. Total plasma ropivacaine concentration was measured. RESULTS Group R showed a significant reduction in postoperative pain at rest and on mobilization, while rescue medication requirements were greater in Group M. Total ropivacaine plasma concentration remained below toxic concentrations and no adverse effects occurred. Length of hospital stay was shorter in Group R. CONCLUSION Infiltration and wound instillation with ropivacaine 0.2% is more effective in controlling postoperative pain than systemic analgesia after major joint replacement surgery.

Abstract
PURPOSE The purpose of this article was to investigate the relationship between analgesia, sedation, and memory of intensive care. PATIENTS AND METHODS One hundred fifty-two adult, cooperative intensive care unit (ICU) patients were interviewed 6 months after hospital discharge about their memory of intensive care. The patient was considered to be cooperative when he/she was aware of self and environment at the interview. The patients were grouped as follows: A (45 patients) substantially no sedation, B (85) morphine, and C (22) morphine and other sedatives. RESULTS The patients having no memory of intensive care were 38%, 34%, and 23% respectively, in the three groups. They were less ill, according to SAPS II (P <.05), and had a shorter ICU stay (P <.01). Group C patients were more seriously ill according to SAPS II, duration of mechanical ventilation, and length of stay in ICU and in hospital (P <.001). The incidence of factual, sensation, and emotional memories was not different among the three groups. Females reported at least one emotional memory more frequently than males (odds ratio 4.17; 95% CI 10.97-1.59). CONCLUSIONS The patients receiving sedatives in the ICU are not comparable with those receiving only opiates or nothing, due to the different clinical condition. The lack of memory of intensive care is present in one third of patients and is influenced more by length of stay in ICU than by the sedation received. Sedation does not influence the incidence of factual, sensation, and emotional memories of ICU admitted patients. Females have higher incidences of emotional memories than males.

Abstract
OBJECTIVE To develop a questionnaire about quality of life (QV) suitable for Intensive Care Unit (ICU) patients. DESIGN Two prospective studies by direct interviews; in the first one the questionnaire was answered before and after surgical intervention and in the second during ICU stay and six months after hospital discharge. SETTING Surgical ward and surgical-medical ICU. MATERIALS AND METHODS Adult, co-operative patients, resident near the hospital, who gave informed consent have been interviewed. The following items of QOL were investigated: residence, physical activity, social life, perceived QV, oral communication and functional limitation, considering age. The last two items were assessed by the interviewer. RESULTS Inter-observer reliability on oral communication and functional limitation, assessed by two interviewers in 87 surgical patients, was good (p = 0.68 and p = 0.72 respectively). Validation of the questionnaire in 37 surgical cases showed worsening in all the items, consistent with theoretical prediction. In the 152 ICU consecutively admitted eligible patients, physical activity, social life, functional limitation and global QV (sum of all the investigated items) significantly changed. Residence, perceived QV and oral communication did not change. Internal consistency of the instrument was good (p < 0.05). CONCLUSIONS The evaluative instrument studied shows good reliability and validity. The authors suggest a shorter questionnaire could be tested in future investigations.

Abstract
OBJECTIVE To investigate memory for postoperative pain in Intensive Care Unit (ICU) admitted patients after hospital discharge. DESIGN Prospective study by direct interviews. METHODS Six months after hospital discharge, we interviewed adult, postoperative, co-operative patients consecutively admitted to ICU for more than 24 hrs, resident near the hospital, who gave informed consent. We investigated intensity of postoperative pain and recollections of critical care reported by patients. The following data were collected from medical records: type and duration of surgical intervention, type of anaesthesia and fentanyl dose, severity of illness at ICU admission, ICU and hospital (after ICU) length of stay and postoperative administration of morphine. RESULTS Of 130 patients interviewed, 82 (63%) reported no pain, 27 (21%) low and 21 (16%) more than low pain. Among these 3 groups of patients, there was no statistically significant difference in all the variables collected from medical records. Patients who remembered more than low pain recorded emotional distress more frequently (p < 0.001) and physical discomfort less frequently (p < 0.01) than patients whose pain was absent or low. CONCLUSIONS Most patients report that postoperative pain, during their ICU stay, was absent or low. Emotional distress seems to be related to memory for postoperative pain.

Abstract
OBJECTIVE To determine survival and changes in quality of life (QOL) after hospital discharge in patients who had stayed in an intensive care unit (ICU). DESIGN Prospective study by direct interviews during ICU stay and 6 months after hospital discharge. SETTING Surgical-medical ICU. PATIENTS AND METHODS We interviewed cooperative, adult patients admitted consecutively to the ICU for more than 24 h, living near the hospital, who gave informed consent. The following QOL domains were investigated: residence, physical activity, social life, perceived QOL, oral communication and functional limitation. RESULTS One-year survival was 82.4% (predicted 84%). Mortality was 36.3% after urgent neoplastic surgery, 19.4% for medical admissions and 4.9% after non-neoplastic surgery. Of 160 patients studied, eight cases, older and already deteriorated at the first interview, could not respond to the perceived QOL item after ICU discharge. In the other 152 patients, physical activity was reduced in 31% (usually slightly), social life had worsened in 32% and functional limitation increased in 30%. The perceived QOL did not change. CONCLUSIONS After hospital discharge, the survival of ICU-admitted patients is comparable to that of the general population and not related to ICU treatments. Most patients maintain their physical activity and social status at the preadmission level. Any worsening, if present, is slight and does not influence perceived QOL.

Abstract
Time Resolved Reflectivity during XeCl pulsed laser irradiation of amorphous silicon films deposited on glass was measured. Simulation of the process by a Heat Flow Calculation in which explosive crystallization was not forced to occur, predicts the coexistence of partial bulk nucleation and a traveling molten layer. Optical simulation of Time Resolved Reflectivity was used to critically examine the Heat Flow Calculation results, substantially confirming the existence of a mixture of thermodynamical phases.

Abstract
Empty sella syndrome is an anatomical entity in which the pituitary fossa is enlarged and partially filled with cerebrospinal fluid owing to the arachnoid herniation, while the pituitary gland is compressed against the posterior rim of the fossa. This condition can be due to an inherent weakness of the diaphragm sella and/or to an increase in intracranial pressure which promote the herniation of the arachnoid membrane into the pituitary fossa (primary empty sella) or it can results following surgery, radiation or vascular and tumorous pituitary diseases (secondary empty sella). Empty sella can be associated with neuroradiological and endocrine symptoms. This study reports the clinical, endocrine, and roentgenographic features in 20 patients with primary empty sella syndrome. Disturbances of hypothalamic-pituitary function were detected in 6 patients (hyperprolactinemia, hypopituitarism, central diabetes insipidus, hypothalamic hypothyroidism). Three patients exhibited hypergonadotropic hypogonadism. This report supports the following conclusions: a) there is no correlation between size of pituitary fossa, type an extension of arachnoid herniation and the degree of hypothalamic-pituitary dysfunction; b) endocrine alterations are frequent in the empty sella syndrome; c) the association of empty sella and primary diabetes insipidus is not a very rare event.

Abstract
The effects of pirenzepine (P), a cholinergic muscarinic antagonist, on growth hormone (GH) and prolactin (PRL) response to dermorphin (D) were studied in a group of 7 healthy men. D produced clear elevations in GH and PRL levels. P completely blocked the GH-releasing activity of D, whereas it did not alter the PRL-releasing activity. These results indicate that GH-releasing action of D is mediated via the central cholinergic nervous system in man.

Abstract
The aim of this study was to investigate further the influence of dermorphin (D), a new potent opioid peptide (H-Tyr-D-Ala-Phe-Gly-Tyr-Pro-Ser-NH2), on the functional activity of the pituitary-adrenocortical system in man. Six normal men were treated with oral metyrapone to stimulate the secretion of ACTH, beta-lipotropin, and beta-endorphin. In these subjects, significant suppression of metyrapone-evoked release of ACTH and related peptides occurred during D infusion (5.5 micrograms/kg X min for 30 min) compared with that during saline infusion. These results indicate that D can induce a significant decline in plasma levels of ACTH, beta-lipotropin, and beta-endorphin, the major circulating peptides from the C-terminal part of proopiocortin, and suggest that opioid peptides may be involved in the control of the functional activity of pituitary-adrenocortical activity in man.

Abstract
We have recently shown that dermorphin (D), a new potent opioid peptide (H-Tyr-D-Ala-Phe-Gly-Tyr-Pro-Ser-NH2) stimulates prolactin (PRL) and growth hormone (GH) secretion in humans. In 11 patients with a PRL-secreting pituitary adenoma (eight microprolactinomas and three macroprolactinomas with suprasellar extension), diagnosed by pituitary dynamic function tests, and radiological evidence with confirmation at surgery, the PRL and GH responses to D were studied to evaluate the effect of pathological hyperprolactinemia on the opioid-induced secretion of GH and PRL. No PRL response to D was observed in all 11 patients. Plasma GH increased after D in all patients, except in three patients bearing a macroprolactinoma. This study shows that the effect of D on PRL and GH secretion can be dissociated in patients with PRL-secreting pituitary adenoma, perhaps for a different derangement in the hypothalamic-pituitary mechanism(s) underlying the opioidergic regulation of GH and PRL secretion. In addition our data indicate that D can be employed as a useful opioid probe in humans.

Abstract
The effect of a recently described, potent opioid peptide, dermorphin (DER), on TSH secretion in euthyroid subjects has been studied. DER infused at a rate of 5.5 micrograms/Kg/min for 30 min induced a significant increase in serum TSH concentration at 60, 90, and 120 min after the infusion was begun. Treatment with naloxone administered 30 min before the DER infusion with a bolus dose of 4 mg, followed by a constant infusion of 1 microgram/Kg/min for 150 min, prevented the rise in serum TSH. Naloxone administered alone did not induce any change in TSH concentration. The present findings suggest that DER has a stimulatory effect on TSH secretion, probably mediated by opioid receptors. These results, however, do not solve the question as to whether opioids have a physiological role in the control of pituitary TSH secretion.

Abstract
This study was designed to investigate the effect of dermorphin (D), a new synthetic potent opiate-like peptide (H-Tyr-D-Ala-Phe-Gly-Tyr-Pro-Ser-NH2), on PRA, plasma aldosterone (PA), plasma cortisol (PC), and plasma ACTH levels in normal men. D infusion (5.5 micrograms/kg X min for 30 min) significantly increased PRA (P less than 0.01) and decreased PC levels (P less than 0.02). D produced a small decrease in ACTH and a small increase in PA. Pretreatment with the opioid receptor antagonist naloxone (N) blunted the D-induced PRA increase and completely prevented the D-induced PC decrease, but enhanced PC and ACTH levels. These data indicate that the action of D is mediated through opioid receptors, and are consistent with the conclusion that 1) D, a new opioid peptide, increases PRA levels, perhaps via activation of the sympathetic nervous system, providing evidence that opioid peptides may exert an influence on renin secretion; and 2) D suppresses PC levels, perhaps by affecting ACTH secretion, corroborating previous observations that opioid peptides might affect the function of the pituitary-adrenocortical axis.

Abstract
Two new related heptapeptides (dermorphins) with potent central and peripheral opiate-like activity have been isolated from the skin of South American frogs, and have been chemically characterized as H-Tyr-D-Ala-Phe-Gly-Tyr-Pro-Ser-NH2 (dermorphin) and H-Tyr-D-Ala-Phe-Gly-Tyr-Hyp-Ser-NH2 (Hyp6-dermorphin). The response of GH to infusion of a synthetic dermorphin (5.5 micrograms/kg/min for 30 min) was studied in 9 healthy men. Dermorphin (D) significantly increased plasma growth hormone (GH) concentrations. The GH response to D was blunted by prior administration of naloxone, suggesting that D interacts with mu-type opiate receptors. However, the evaluation of the physiological significance of D-induced GH release in humans requires further study.

Abstract
Dermorphins (D) are heptapeptides (H-Tyr-D-Ala-Phe-Gly-Tyr-X-Ser-NH2; X, Pro or Hyp) with powerful central and peripheral opiate-like activity, originally isolated from the skin of South American frogs. To study the effect of a synthetic D on PRL secretion in man, either D (5.5 micrograms/kg . min for 30 min) or D-placebo (0.9% saline) infusion over 30 min was administered iv in random sequence to 11 volunteers (6 women and 5 men). In all the subjects, D induced a significant increase in the levels of PRL, more consistently in women than in men. To investigate whether the increase in PRL was due to the opiate agonist properties of D, the study was repeated in the same subjects during naloxone infusion. The PRL response to D was completely suppressed, suggesting that the peptide exerts its effect on PRL release via an opiate receptor stimulation of the mu-type. These data allow us to conclude that D may affect PRL release in humans; however, further investigation is necessary before any physiological significance might be attributed to D in man.

Abstract
To estimate the possible involvement of a peripheral serotonergic pathway in the mechanism of the aldosterone-stimulating effect of metoclopramide (M) the plasma aldosterone (PA), renin activity (PRA) and prolactin (PRL) response to M was studied in 6 normal subjects before and after administration of ketanserin (K), a pure, specific, and selective blocking agent of 5-hydroxytryptamine type 2 (5-HT2) receptors. With K preadministration the M-induced increase of PRL was similar to that observed in control conditions, in accordance with the specific and peripheral antiserotonergic action of the drug. K potentiated the PA and PRA elevation in response to M. These data suggest that the PA response to M is not related to M's agonist activity at the peripheral 5-HT2 receptors level. The results further indicate that K can induce an enhancement of the activity of renin-angiotensin-aldosterone system with an higher PRA and PA response to stimulatory action of M.
