13. Serum ghrelin levels in papillary thyroid carcinoma
ABSTRACT Objective Ghrelin plays a role in several processes of cancer progression, and numerous cancer types express ghrelin and its receptor. We aimed to investigate serum levels of ghrelin in patients with papillary thyroid carcinoma (PTC) and its association with the prognostic factors in PTC. Materials and methods We enrolled 54 patients with thyroi

14. Ghrelin plasma levels, gastric ghrelin cell density and bone mineral density in women with rheumatoid arthritis
Generalized bone loss can be considered an extra-articular manifestation of rheumatoid arthritis (RA) that may lead to the occurrence of fractures, resulting in decreased quality of life and increased healthcare costs. The peptide ghrelin has demonstrated to positively affect osteoblasts in vitro and has anti-inflammatory actions, but the studies that correl

15. Ferulic acid lowers body weight and visceral fat accumulation via modulation of enzymatic, hormonal and inflammatory changes in a mouse model of high-fat diet-induced obesity
Previous studies have reported on the glucose and lipid-lowering effects of ferulic acid (FA) but its anti-obesity potential has not yet been firmly established. This study investigated the possible anti-obesitogenic effects of FA in mice fed a high-fat diet (HFD) for 15 weeks. To assess the antiobesity potential of FA, 32 male Swiss mice, weighing 20–25 g

16. Determination of the regulatory properties of Yucca schidigera extracts on the biochemical parameters and plasma hormone levels associated with obesity
ABSTRACT Yucca schidigera Ortgies, Asparagaceae, is a herbaceous plant. Due to the high saponin content the powdered branches and leaves are used as natural food additive for human and animal. The aim of this study was to investigate the effects of Y. schidigera extracts on plasma leptin, ghrelin, adiponectin, insulin, thyroid hormones and some biochemical p

17. Expression of Ghrelin and GHSR-1a in Long Term Diabetic Rat's Kidney
The aim of this work was to study the relative ghrelin and growth hormone secretagogue receptor (GHS-R)1a gene expression in the kidney of long-term diabetic rats. Forty male Wistar albino rats were divided into four groups: C- control group, DI- one month diabetic rats group, DII- two months diabetic rats group, and DIII- three months diabetic rats group. D

18. 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

19. Ghrelin attenuates the growth of HO-8910 ovarian cancer cells through the ERK pathway
Ovarian cancer is one of the most common causes of death from gynecologic tumors and is an important public health issue. Ghrelin is a recently discovered bioactive peptide that acts as a natural endogenous ligand of the growth hormone secretagogue receptor (GHSR). Several studies have identified the protective effects of ghrelin on the mammalian reproductiv

20. Ghrelin and eating disorders
Background Ghrelin is a potent hormone with central and peripheral action. This hormone plays an important role in the regulation of appetite, food intake, and energy balance. Studies have suggested that ghrelin is involved with eating disorders (ED), particularly bingeing and purging. Genetic variants have also been studied to explain changes in eating beh

21. Evaluation of immunohistochemical expression of ghrelin-producing rectal cells in Wistar rats underwent to the cafeteria diet
PURPOSE:To investigate the impact of cafeteria diet on ghrelin expression in rectal tissue and identify the morphologic cell type. METHODS:Twenty-four male Wistar rats were divided into four subgroups of six animals each: RC1 (rat chow 1) and CAF1 (cafeteria diet 1) for a period of 30 days; RC2 (rat chow 2) and CAF2 (cafeteria diet 2) for a period of 60 days

22. The effects of ghrelin on colonic anastomosis healing in rats
OBJECTIVES: In addition to its roles in the stimulation of growth hormone secretion and the regulation of appetite and metabolism, ghrelin exerts immunomodulatory, anti-inflammatory and antioxidant actions in several organ systems. In this study, we investigated the effects of ghrelin on the healing of experimental colonic anastomoses. METHODS: Wistar rats w

23. Influência de variantes no gene do receptor secretagogo do hormônio do crescimento (GHSR) na obesidade e no risco de compulsão alimentar e síndrome metabólica em crianças e adolescentes obesos / Influence of growth hormone secretagogue receptor (GHSR) gene variants in obesity and risk of binge eating and metabolic syndrome in obese children and adolescents
A prevalência da obesidade vem aumentando em todas as idades e na população infantil é considerada um problema de saúde pública. Os fatores relacionados à patogênese da obesidade não estão completamente elucidados, envolvendo questões comportamentais, biológicas, hormonais, culturais e genéticas. O comportamento alimentar é regulado pelo eixo h

24. Distribuição da ghrelina e de seu receptor na mucosa gástrica de ratos submetidos ao desmame precoce: efeitos sobre a proliferação celular epitelial. / Ghrelin and growth hormone secretagogue receptor distribution in the gastric mucosa of early weaned rats: effects on epithelial cell proliferation.
Investigamos a distribuição de ghrelina e de seu receptor (GHS-R) na mucosa gástrica de ratos durante a terceira semana de vida pós-natal e avaliamos o efeito do desmame precoce sobre estas moléculas. Estudamos também a participação da ghrelina no controle da proliferação celular do epitélio gástrico, e para tanto utilizamos a administração de
