Adrenal incidentalomas are defined as asymptomatic adrenal masses occasionally discovered during high-resolution imaging procedures such as computed tomography (CT) or magnetic resonance (MR). Pheochromocytoma, a potentially lethal chromaffin tumour, must be excluded before any invasive diagnostic procedures to avoid massive catecholamines release. Chromogranin A (CgA) is a member of the granin...

A critical requirement in neuroendocrine tumor (NET) management is a blood biomarker test that is sensitive, specific and reproducible. We evaluated a PCR-based 51-transcript signature to detect tumors, compared it with chromogranin A (CgA) and examined the confounding effect of proton pump inhibitors (PPIs), which cause falsely elevated CgA levels. The multigene signature was evaluated in two ...

The estrogen receptor (ER) status of breast tumors is used to identify patients who may respond to endocrine agents such as tamoxifen. However, ER status alone is not perfectly predictive, and there is a pressing need for more reliable markers of endocrine responsiveness. Here, we identified the well-known CGA gene (coding for the alpha subunit of glycoprotein hormones) as a new ERalpha-respons...

PURPOSE In this work we explore a method named clinical grading analysis (CGA) which is based on clinical assessments performed by radiation oncologists (ROs). The purpose is to investigate how useful the method is for treatment plan comparisons, and how the CGA results correlate with dosimetric evaluation parameters, traditionally used for treatment plan comparisons. MATERIAL AND METHODS Hel...

Elevated circulating chromogranin A (CgA) levels are found in neuroendocrine tumors (NETs), but the diagnostic usefulness of this marker is still debatable. To assess the role of CgA for the diagnosis of gastroenteropancreatic (GEP) NETs and the identification of metastatic patients, an Italian multicenter observational study has been performed. CgA was evaluated in 202 GEP NET patients by IRMA...

Root hairs, which arise from root epidermal cells, are tubular structures that increase the efficiency of water absorption and nutrient uptake. A low pH (pH 4) medium induced root hair formation in lettuce (Lactuca sativa L.) seedlings, and the decapitation of shoots inhibited root hair formation. The addition of shoot extract to the medium restored root hair formation in the decapitated lettuc...

Little is known about the reliability of G8 screening tool and the prognostic value of clinical parameters within the Comprehensive Geriatric Assessment (CGA) in clinically fit older patients with haematological malignancies. This study was performed to assess the reliability of G8 as a screening tool and to determine the predictive value of CGA items in terms of one-year overall survival (OS)....

Secretin evokes catecholamine secretion from PC12 pheochromocytoma cells. We tested whether secretin activates transcription of the major vesicular core protein chromogranin A (CgA). Secretin stimulated both endogenous CgA gene transcription (approximately 4-6-fold) as well as transfected CgA promoter activity (approximately 8-10-fold; EC50, approximately 7 nm) in PC12 cells. Studies on CgA pro...

BACKGROUND Medial patellofemoral ligament (MPFL) is the main restrictor of lateral shifting of the patella, contributing by 60 % in the first 20° flexion of the knee. MPFL reconstruction has been performed in order to restore the stability of the patella with good results.Lyophilized Gracilis tendon allograft (LGA) compared to Cryopreserved Gracilis tendon allograft (CGA) has a lower cost, does...

Background Frailty can be screened using the Clinical Scale (CFS) and quantified a Index (FI) based on deficit accumulation. Higher degrees of frailty have been associated with greater risks adverse outcomes, including dementia. Comprehensive Geriatric Assessment (CGA, allows development individualized care plans for older adults’) has used to derive an FI-CGA. To promote effective assessment o...
