1. The effects of macronutrients composition on hormones and substrates during a meal tolerance test in drug-naive and sitagliptin-treated individuals with type 2 diabetes: a randomized crossover study
ABSTRACT Objectives: To evaluate the effect of sitagliptin treatment in early type 2 diabetes mellitus (T2DM) and the impact of different macronutrient compositions on hormones and substrates during meal tolerance tests (MTT). Materials and methods: Half of the drug-naive patients with T2DM were randomly assigned for treatment with 100 mg of sitagliptin, q

2. Binge eating disorder, frequency of depression, and systemic inflammatory state in individuals with obesity – A cross sectional study
ABSTRACT Objective: Binge eating disorder (BED) is the most prevalent eating disorder in individuals with obesity. Its association with factors that control hunger and satiety has not yet been elucidated. We evaluated whether levels of inflammatory markers, frequency of psychiatric comorbidities, and appetite-related hormones levels differ between individua

3. Enuresis and upper airway obstruction: BNP and ADH hormones behavior before and after airway surgery
ABSTRACT Introduction: Upper airway obstruction (UAO) is a common condition in all pediatric population, with a 27% prevalence. Primary monosymptomatic nocturnal enuresis (PMNE) is a condition related to UAO in 8% to 47% of these children. The specific pathophysiological mechanism of this bond is not well understood. Some authors suggest a connection betwee

4. Determinants of body weight regulation in humans
ABSTRACT Body weight is regulated by the ability of hypothalamic neurons to orchestrate behavioral, endocrine and autonomic responses via afferent and efferent pathways to the brainstem and the periphery. Weight maintenance requires a balance between energy intake and energy expenditure. Although several components that participate in energy homeostasis have

5. From Escherichia coli heat-stable enterotoxin to mammalian endogenous guanylin hormones
The isolation of heat-stable enterotoxin (STa) from Escherichia coli and cholera toxin from Vibrio cholerae has increased our knowledge of specific mechanisms of action that could be used as pharmacological tools to understand the guanylyl cyclase-C and the adenylyl cyclase enzymatic systems. These discoveries have also been instrumental in increasing our un

6. Identificação da subtilase responsável pelo processamento do prepopeptídeo AtRALF1 em Arabidopsis thaliana / Identification of the subtilase responsible for the prepropeptide AtRALF1 processing in Arabidopsis thaliana
Desde a década de 90, uma nova família de moléculas de origem protéica e com características hormonais vem sendo estudada em plantas. Esse grupo de novas moléculas, coletivamente chamado de peptídeos hormonais, está envolvido com defesa, reprodução, crescimento e desenvolvimento. RALF, que é um desses novos peptídeos, é ubíquo em plantas e est�

7. Correlations of circulating peptide YY and ghrelin with body weight, rate of weight gain, and time required to achieve the recommended daily intake in preterm infants
The objective was to elucidate the relationships between serum concentrations of the gut hormone peptide YY (PYY) and ghrelin and growth development in infants for potential application to the clinical observation index. Serum concentrations of PYY and ghrelin were measured using radioimmunoassay from samples collected at the clinic. For each patient, gestat

8. Regulação endócrina de curto prazo de hormônios relacionados à fome em mulheres obesas que apresentam episódios de compulsão alimentar / Short-term endocrine regulation of hunger related hormones in obese women with binge eating episodes
Binge eating is associated to several diseases, including obesity. In order to study the hormonal control of hunger and satiety that is commonly involved in binge-eating process; we evaluated the serum concentration of these hormones in adult women. The experimental study was composed of 3 groups, n= 23: Lean (GE, n = 8), Obese without binge (GO, n = 7) and

9. Identificação e caracterização de componentes da via de transdução de sinais do peptídeo hormonal RALF / Identification and characterization of components of the peptide hormone RALF signaling transduction pathway
As pesquisas com os peptídeos hormonais de plantas se iniciaram na década de noventa com a descoberta da sistemina. Hoje existem diversos peptídeos identificados, e alguns deles já em avançado estágio de caracterização. O envolvimento desta classe de moléculas em diversas funções básicas e específicas da biologia dos vegetais despertou o interes

10. Análise da ação do ACTH e do peptídeo N-terminal da POMC na proliferação, morte celular e na expressão das proteínas de genes de resposta secundária na supra-renal de ratos hipofisectomisados ou tratados com dexametasona. / Analysis of ACTH and the peptide N-terminal POMC in proliferation, cell death, and expression of secondary response genes in adrenal glands of hypophysectomized or dexamethasone treated rats.
Different experimental models have been used to study the trophic action of ACTH in adrenal, which seems to be important in proliferation and cell death in vivo. This hypothesis was tested using hypophysectomized or dexamethasone treated rats, and through IHC we evaluate: 1-the BrdU incorporation in different adrenal cortex zone after i.p. of ACTH, FGF2 or N

11. Propriedades termodinâmicas da Prolil Oligopeptidase de Trypanosoma brucei
Trypanosoma brucei secrets a prolyl oligopeptidase (POPTb) which is possibly involved in the pathogenesis of sleeping sickness. It is able to hydrolyze prolinecontaining peptide hormones and is therefore considered a good target for the development of drugs to treat the disease. As the crystal structure of POPTb has not been solved yet, we used circular dich

12. ExpressÃo de cinco diferentes proteÃnas de interesse farmacolÃgico em sementes transgÃnicas de soja [Glycine Max L. (Merril)]
Superior plants represent a convenient system for large-scale production of heterologous proteins. Its potential has been confirmed by the commercial success of such production systems, based on genetic transformation of a broad range of vegetable species, resulting in efficient production of more than 100 different heterologous proteins. A representative pe
