BACKGROUND The derivation of a frailty index (FI) based on deficit accumulation from a Comprehensive Geriatric Assessment (CGA) has been criticised as cumbersome. To improve feasibility, we developed a questionnaire based on a CGA that can be completed by care partners (CP-FI-CGA) and assessed its validity. METHODS We enrolled a convenience sample of patients aged 70 or older (n=203) presenti...

Chlorogenic acids (CGA) are cinnamic acid derivatives with biological effects mostly related to their antioxidant and antiinflammatory activities. Caffeoylquinic acids (CQA) and dicaffeoylquinic acids (diCQA) are the main CGA found in nature. Because green coffee is a major source of CGA, it has been used for production of nutraceuticals. However, data on the bioavailability of CGA from green c...

OBJECTIVE In atrophic body gastritis (ABG) chronic hypergastrinaemia stimulates enterochromaffin-like (ECL) cell proliferation with development of cell hyperplasia, dysplasia and possibly type-1 gastric carcinoids. As circulating chromogranin A (CgA) levels are a marker of neuroendocrine tumours, we evaluated the clinical usefulness of CgA assay in ABG patients to detect those with carcinoids. ...

Candida species (Candida spp.) are important fungal pathogens, which cause numerous clinical diseases associated with significant mortality and morbidity in healthcare settings. In our previous study, we identified a recombinant peptide, chromogranin A (CGA)-N46, corresponding to the N-terminal Pro31-Gln76 sequence of human CGA, that exhibited antifungal activity against Candida albicans. The p...

There is an urgent need to search for novel chemosensitizers in the field of cancer therapy. Chlorogenic acid (CGA), a type of polyphenol present in the diet, has many biological activities. The present study is designed to explore the influence of CGA on the effects of 5-fluorouracil (5-FU) on human hepatocellular carcinoma cells (HepG2 and Hep3B). Treatment with 5-FU induced the inhibition of...

Chromogranin A (CgA) is the index member of the chromogranin/secretogranin (or 'granin') family of regulated secretory proteins that are ubiquitously distributed in amine- and peptide-containing secretory granules of endocrine, neuroendocrine and neuronal cells. Because of their abundance and such widespread occurrence, granins have often been used as prototype proteins to elucidate mechanisms ...

Chromogranin A (CGA) is the major protein of the secretory granule from chromaffin cells and also is found in a variety of endocrine cells. Although the sequence of this acidic glycoprotein has been elucidated recently, its biological function is unknown. Here we have purified CGA from chromaffin granules; the final preparation contained the 74-kDa native CGA together with two degradation produ...

The biogenesis of dense-core secretory granules (DCGs), organelles responsible for the storage and secretion of neurotransmitters and neuropeptides in chromaffin cells, is poorly understood. Chromogranin A (CgA), which binds catecholamines for storage in the lumen of chromaffin granules, has been shown to be involved in DCG biogenesis in neuroendocrine PC12 cells. Here, we report that downregul...

Background: Hospitalization has been widely accepted for elderly patients with acute or chronic disease. However, hospitalization is also thought to be a risk factor for delirium in hospitalized elderly patients The aim of this study is to assess the efficiency of Comprehensive Geriatric Assessment (CGA) nursing strategy for elderly patients with Coronary Heart Disease (CHD) during hospitalizat...

The health benefit of coffee consumption mainly depends on chlorogenic acid (CGA), one its major active phenolic constituent. CGA have several biological properties like anticancer, antihypertensive, hepatoprotective, neuroprotective, renoprotective, antimicrobial etc. It is assumed that different forms contains amount CGA. In this regards, we developed and validated a simple cost effective chr...
