Abstract Objectives: To assess body composition and relationships among body composition, appetiterelated hormones, adipocytokines, and heart failure (HF) in adult patients with congenital heart disease (CHD).
Patients: This prospective study enrolled 46 consecutive adult patients with CHD and 12 agematched healthy controls. The patients and control subjects were divided into four groups: 13 patients with Fontan circulation (group A), 16 patients with cyanosis (group B), 17 patients who previously underwent biventricular repair (group C), and 12 age-matched healthy controls.
Design: Body composition was measured using InBody730, and levels of appetite-related hormones (ghrelin and leptin) and adipocytokines (leptin, interleukin-6, and… More >

Abstract Maize (Zea mays L., the third most important cereal crop after wheat and rice, is the major kharif (summer) crop of rainfed areas in Pakistan. The yield per hectare and total production of maize in Pakistan is low versus an exponentially increasing population. The objective of this work was to study the interactive effects of phytohormones [Gibberellic acid (GA), Sodium nitroprusside (SNP), Abscicic acid (ABA) and kinetin (KIN)] on morphological, physiological and biochemical parameters during the germination of maize seeds. Seeds were presoaked in different hormones, separately or in combinations. Priming with GA+SNP+ABA+KIN enhanced the total More >

Abstract Robinia pseudoacacia (locust hereafter) is an ornamental tree with various uses. Both homologous tetraploid (tetraploid hereafter) and diploid cultivars are commercially available. The tetraploids have advantageous traits, but poor germinability, and cuttings are difficult to root. Since auxin applications can promote rooting, we evaluated the effects of dipping cuttings in various indole-3-butyric acid (IBA) concentrations for four hours on rooting parameters. IBA significantly affected all measured parameters of both tetraploid and diploids cuttings. Tetraploid cuttings produced no roots without IBA. The effects were strongest at 1000 and 800 mg/L IBA for tetraploids and diploids, respectively. Values… More >

Abstract Triatoma infestans, a blood-feeding insect, synchronises physiological mechanisms leading to moult with food intake. Since the corpora allata are important in moult and metamorphosis regulation, we have studied morphological changes in 4^th instar nymphs (gland size, cell density, percent of animals showing mitoses and cell size). Changes were correlated with the effect of precocene II, epidermal proliferation, and with the extent of the “head critical period”. Based on morphological grounds, three stages can be defined in the gland along the 4^th instar: Stage 1 (days 0-2 after feeding) showed small corpora allata, composed by a small number… More >

Abstract Two independent parameters, epicotyl height (cm) and number of induced buds were studied on Pinus pinaster explants to analyse the effects of three phytohormones (6-benzylaminopurine, jasmonic acid, ethylene) which were combined or not in 11 different treatments. Epicotyle length diminished significantly in relation to the control medium (medium without exogen phytohormones) in presence of jasmonic acid, 6-benzylaminopurine or Ethephon (which is converted to ethylene in plants) in any of treatments. Concentrations of 100 μM of jasmonic acid and Ethephon had a greater inhibitory effect than the treatments with 10 μM. In addition to that, jasmonic acid… More >

Abstract Risk categorization based on pre-treatment PSA, clinical stage and Gleason score is now widely used in the management of patients with localized prostate cancer. In patients with low-risk disease (cT1-T2a, PSA < 10 ng/ml and Gleason score ≤ 6) there is no role for the routine use of adjunctive hormonal therapy. In intermediate-risk patients (T1-T2, PSA < 20 ng/ml and Gleason ≤ 7) there is some evidence to suggest improved outcomes with neo-adjuvant hormonal therapy when low-dose external beam radiation therapy (EBRT) is used. However, with appropriate modern dose EBRT there is little data to More >

Abstract Prior to this work, we found that adrenal as well as extra-adrenal factors activate the response of renal 11ß-hydroxysteroid dehydrogenase 2 to stressful situations. These results -showing ways through which the organism hinders the pathological occupation of mineralocorticoid receptors by glucocorticoids leading to sodium retention and hypertension- prompted the present study on the nature of the above-mentioned extraadrenal factors. Serotonin was chosen because of its properties as a widely distributed neurohormone, known to interact with glucocorticoids at many sites, also exhibiting increased levels and effects under stressful situations. We studied serotonin effects on 11ß-hydroxysteroid dehydrogenase… More >

Abstract Age is the most important factor associated with sexual dysfunction. The traditional thinking explained this association by the neurovascular events developing with the aging process. More recently, central neuro-endocrine mechanisms resulting from apoptosis in the hypothalamic areas involved in both the production of sex hormones and the control of sexual processes have added a new dimension to human sexuality. This evidence is still controversial but of unquestionable importance in our understanding of endocrine alterations and sexual shortcomings associated with aging. More >

Abstract Purpose: Although human renal cell carcinoma (RCC) is considered refractive to hormone therapy, this lesion can be induced in the Syrian hamster by exogenous estrogen. Human RCC also has been demonstrated to contain estrogen receptors. Since there are significant changes of estrogen levels during pregnancy, we wanted to investigate if there were any associations between the hormonal variations of pregnancy and renal cancer in women using two distinct cohorts.
Materials and methods: We reviewed the charts of 57 females who presented for treatment of renal cancer. We assessed the size of each tumor radiologically and pathologically, the… More >

Abstract The Genito-Urinary Radiation Oncologists of Canada (GUROC) have produced a consensus statement on radiotherapy in prostate cancer. This paper summarizes the consensus statement with regard to risk grouping and the role of hormones and radiotherapy. Survival is the most important outcome in the assessment of patients treated with radiotherapy. Other outcomes of interest include disease­free survival, metastatic-free survival, local control, biochemical measures, toxicity, efficacy, and quality of life. Risk groupings based on prognostic data are increasingly used in the management of prostate cancer. These groupings have been correlated to prognosis in several studies, and are… More >
