Comprehensive geriatric assessment (CGA) is a multidimensional and multidisciplinary diagnostic process focused on determining the clinical profile, pathological risk, residual skills, short- and long-term prognosis, and the personalized therapeutic and care plan of the functionally compromised and frail older subjects. Previous evidence suggested that the effectiveness of CGA programs may be influenced by the settings where the CGA is performed [i.e., hospital, post-hospital discharge/ long-term care facilities (LTCF), or community/home] as well as the specific clinical conditions of older frail individuals...

BACKGROUND: To improve the effectiveness of community-based care programs, especially those targeting the oldest-old population (80+), data are needed that elucidate those factors associated with a successful response to the intervention. Two comparable nurse-led care programs have been evaluated in two large randomized controlled trials (RCTs), one in Switzerland and one in the Netherlands. AIMS: To identify common patient characteristics that are related to a successful response to proactive nurse-led care, we explored if and to what extent, identical factors were present in both study populations...

1. Chlorogenic acids (CGAs), one kind of major bioactive constituents isolated from Flos Lonicerae Japonicae, possess many biological activities, such as antibacterial, antioxidant, and antiviral activities. In this study, we established an efficient strategy using ultra-high-performance liquid chromatography coupled with linear ion trap-Orbitrap mass spectrometry (UHPLC-LTQ-Orbitrap MS) to profile the in vivo metabolic fate of CGAs in rat urine and plasma. 2. The extract from Flos Lonicerae Japonicae was orally administrated to Sprague-Dawley (SD) rats at a dose of 1000 mg/kg body weight...

The possible health impact of the exposures to Al from environment would be inevitable for humans. Using chelating agents and natural antioxidants against Al-induced biotoxicity become a natural and modern way to prevent the adverse effects of Al in people. This study was undertaken to determine the effectiveness of chlorogenic acid (CGA, 5-O-caffeoylquinic acid) in preventing aluminum chloride (AlCl3) induced hepatotoxicity and hematotoxicity in mice. Control, Al-treated (a single injection of 25 mg Al(3+)/kg, i...

Research on Chromogranin A (CGA) and its derived fragments convincingly demonstrated the multifunctional activity of the 21 amino acid peptide named Catestatin (CST: human CGA352-372, bovine CGA344-364, rat CGA367-387). It is mainly known as an inhibitor of the nicotinic-dependent Catecholamine (CA) release, and an anti-hypertensive peptide, but its role includes a modulation of antioxidant and immune defense, epidermal function, and adipose tissue homeostasis. CST influences the cardiocirculatory system acting both indirectly, via the autonomic nervous system, and directly by influencing the basal cardiac function, and the stretch-dependent myocardial performance...

The high structural diversity of plant metabolites suggests that interactions among them should be common. We investigated the effects of single metabolites and combinations of plant metabolites on insect herbivores. In particular we studied the interacting effects of pyrrolizidine alkaloid (PAs), and chlorogenic acid (CGA), on a generalist herbivore, Frankliniella occidentalis. We studied both the predominantly occurring PA N-oxides and the less frequent PA free bases. We found antagonistic effects between CGA and PA free bases on thrips mortality...

A simple and sensitive electrochemical sensor is constructed for the detection of chlorogenic acid (CGA) based on Au nanoparticles (NPs)/polyoxometalates/3D macroporous carbon (Au-POMs-MPC). Serving as both a reducing and stabilizing agent, the Keggin-type POM, H3PW12O40, is used for the synthesis of stable colloidal Au NPs and then used to link them to MPC at a mild temperature. Because of the unique structural properties and synergetic catalytic effect, Au-POMs-MPC can be developed as an effective sensing platform for the detection of CGA, which showed high activity and excellent analytical performance towards CGA, such as a wide linear range of 2...

In the present study, the complete sequence of the mitochondrial genome (mitogenome) of Daphnis nerii (Lepidoptera: Sphingidae) is described. The mitogenome (15,247 bp) of D.nerii encodes13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and an adenine (A) + thymine (T)-rich region. Its gene complement and order is similar to that of other sequenced lepidopterans. The 12 PCGs initiated by ATN codons except for cytochrome c oxidase subunit 1 (cox1) gene that is seemingly initiated by the CGA codon as documented in other insect mitogenomes...

Comprehensive geriatric assessment (CGA) as a consultative service for older adults with complex medical and psychosocial challenges has existed for decades. However, studies have often showed inconsistent acceptance and implementation of geriatric recommendations by primary care providers (PCPs) raising doubts about the overall benefits of CGA in this setting. Press and colleagues investigated the patient- and provider-related factors that affect recommendation implementation, and like previous studies, they too found similarly low rates of implementation...

AIMS: Treatment decisions for men aged 70 years or over with localised prostate cancer need to take into account the risk of death from competing causes and fitness for the proposed treatment. Objective assessments such as those included in a comprehensive geriatric assessment (CGA) might help to inform the decision-making process. The aim of this study was to describe the CGA scores of a cohort of older men with prostate cancer, evaluate potential screening tools in this population and assess whether any CGA component predicts significant acute radiotherapy toxicity...

INTRODUCTION: Medullary thyroid cancer (MTC) is a malignancy of the thyroid gland, which derives from parafollicular C cells. Periodic measurement of biochemical markers of MTC remains a crucial part of patient follow-up and disease monitoring. The aim of the study was to compare the diagnostic value of four selected markers - calcitonin (Ct), procalcitonin (PCT), chromogranin A (CgA), and carcinoembryonic antigen (CEA). METHODS: Patients with histopathologically confirmed MTC hospitalised in a single department between January 2015 and December 2015 were included in the study...

Wnt signaling is compromised early in the development of human colorectal cancer (CRC) due to truncating nonsense mutations in adenomatous polyposis coli (APC). CRC induced by chemical carcinogens, such as heterocyclic aromatic amines and azoxymethane, in mice also involves dysregulation of Wnt signaling but via activating missense mutations in the β-catenin oncogene despite the fact that genetically modified mice harboring an inactive APC allele efficiently develop CRC. In contrast, activating mutations in β-catenin are rarely observed in human CRC...

The rarity of primary small cell carcinoma of the esophagus (PSCE) has limited the clinical feature and survival analysis with large sample size. Tissue chromogranin A (CgA) protein expression has been reported to be a useful biomarker for diagnosing PSCE. Interestingly, recent studies have indicated tissue CgA as a significant prognostic marker in multiple human cancers, but without PSCE. The present study, thus, was undertaken to characterize the clinicopathological changes and to evaluate the associations of tissue CgA expression with clinical response on Chinese PSCE patients...

Invasive fungal infections threat the life of immunocompromised patients. Chromogranin A N-46 (CGA-N46), corresponding to the 31st to 76th amino acids of the N-terminus of human chromogranin A, is an antifungal peptide. In order to elucidate the antifungal effects of CGA-N46 in vivo, we studied its effects on cell-mediated immunity in Candida krusei-infected mice. The results showed that the treatment with CGA-N46 increased the average body weight and decreased the mortality of the immunocompromised mice model infected with Candida krusei...

BACKGROUND: Patients with chronic kidney disease (CKD) may have increased plasma concentrations of some tumor markers even when no cancer is present. Previous studies have indicated that plasma concentrations of chromogranin A (CGA), cytokeratin 19 fragments (CYFRA 21-1), cancer antigen 125 (CA 125), cancer antigen 19-9 (CA 19-9) and carcinoembryonic antigen (CEA) are higher in patients with CKD but without cancer, than in healthy individuals, and this can make interpretation of results more complicated...

Tunicate, a filter-feeder in seawater, is able to accumulate high amount of metals using intracellular polymer matrices. The woven pyrogallol structures of tunichrome, a small peptide contained in tunicate's blood cells, is believed to be responsible for selective metal sequestration in tunicates from seawater. However, the intriguing tunichrome matrix is difficult both to harvest from the tunicate and to synthesize massively due to the extreme oxidation sensitivity of the pyrogallol moiety which limits the study scope...

Chronic stress can impair brain functions and play a well-known role in the development of stress-related disorders such as anxiety. Melatonin (Mel) is a neurohormone which regulate several physiological processes including mood and behavior. This experimental study was designed to evaluate the effect of Mel on chronic immobilization stress (CIS) for 6 weeks in rats and to elucidate its possible underlying mechanisms. Twenty-eight adult male Wistar albino rats were divided into four equal groups: the control group, the Mel-treated group which was injected daily with Mel (10 mg/kg/day; IP) for 6 weeks, the stressed group which was subjected to CIS protocol daily for 6 weeks, and the Mel-treated stressed group which was injected with Mel and concurrently exposed to CIS protocol for 6 weeks...
