PURPOSE: Calcitonin is the most sensitive tumor marker of medullary thyroid carcinoma (MTC) and a calcium stimulation test is used to improve this sensitivity. In Japan, the electrochemiluminescence immunoassay (ECLIA) is currently the only test performed to measure serum calcitonin. There is a gender difference in the reference value of serum calcitonin; however, a reference upper limit for use with ECLIA has been reported only for women, but not for men. METHODS: We conducted the calcium stimulation test using ECLIA in 21 men with non-medullary thyroid carcinoma (non-MTC), before and after total thyroidectomy...

We report a case of a 66-year-old woman who developed hyperparathyroidism due to a large intrathyroid parathyroid adenoma with episodes of acute pancreatitis. She had previously been treated for acute pancreatitis twice. Serum calcium was 12.4 mg/dL, and intact parathyroid hormone was 253 pg/dL. Ultrasonography and computed tomography of the neck with contrast enhancement revealed a soft tissue mass (28 mm transverse diameter) within the left lobe of the thyroid. (99m)Tc-MIBI scintigraphy demonstrated focal accumulation due to increased radiotracer uptake in the left thyroid lobe...

BACKGROUND: Beside the phosphate binding effect, non-calcium non-aluminum phosphate binder, namely sevelamer hydrochloride (SH), has many other effects in dialysis patients. It can absorb many other compounds, decrease low-density lipoprotein cholesterol (LDL-C) level, and attenuate the progression of vascular calcification; it has been reported to have anti-inflammatory effect. However, it is not clear whether it has any effect on uremic toxins, i.e. serum indoxyl sulfate (IS) and p-cresyl sulfate, (PCS) in hemodialysis (HD) patients...

The Catsper channel is a sperm-specific, Ca(2+)-permeable, pH-dependent, and low voltage-dependent channel that is essential for the hyperactivity of sperm flagellum, chemotaxis towards the egg, capacitation and acrosome reaction. All of these physiological events require calcium entry into sperm cells. Remarkably, Catsper genes are exclusively expressed in the testis during spermatogenesis, and are sensitive to ion channel-induced pH change, such as NHEs, Ca(2+)ATPase, K(+) channel, Hv1 channel and HCO3(-) transporters...

BACKGROUND: Dry immersion (DI), a ground-based model of microgravity previously used in Russia, has been recently implemented in France. The aim of this study was to analyze early events in a short-term DI model in which all conditions are met to investigate who is first challenged from osteo- or adipo-kines and to what extent they are associated to insulin-regulating hormones. METHODS: Twelve healthy men were submitted to a 3-day DI. Fasting blood was collected during pre-immersion phase for the determination of the baseline data collection (BDC), daily during DI (DI24h, DI48H and DI72h), then after recovery (R+3h and R+24h)...

A normal serum calcium level is 8 to 10 mg/dL. The diagnosis of hypercalcemia (ie, levels 10.5 mg/dL or greater) should be confirmed with an albumin-adjusted or ionized calcium level. The two most common causes of hypercalcemia are hyperparathyroidism and malignancy. Drugs, notably lithium and thiazide diuretics, also can cause hypercalcemia. Patients with severe or symptomatic hypercalcemia should be treated initially with hydration to decrease calcium levels. The evaluation should include a parathyroid hormone (PTH) level...

Platelet-Rich Plasma (PRP) is an autologous biological therapy obtained by centrifuging the patient's own blood to concentrate platelets. The addition of autologous thrombin and calcium chloride to PRP allows the production of a semi-solid form called PRP gel. PRP gel is increasingly used in a variety of tissue defects and predominantly in the management of non-healing chronic wounds. The topical application of PRP gel seems promising due to the capability of platelets to store and secrete growth factors (GF), fibrin and cytokines, which are essentials for wound healing...

The major issue in coronary heart disease (CHD) diagnosis and management is that symptoms onset in an advanced state of disease. Despite the availability of several clinical risk scores, the prediction of cardiovascular events is lacking, and many patients at risk are not well stratified according to the canonical risk factors alone. Therefore, adequate risk assessment remains the most challenging issue. Recently, the integration of imaging data with biochemical markers in a radiogenomic framework has been proposed in many fields of medicine as well as in cardiology...

Inhibiting salivary α-amylase is a critical issue of forensic saliva identification using the catalytic method. This study aims to identify human α-amylase inhibitors in forensic saliva screening by using a blue starch amylase test and to measure the extent of enzyme inhibition. Thus, in order to demonstrate the presence of inhibitors, we prepared positively charged metal ion sources or chelators that were mixed into the saliva stains. The results of this study show that ferric chloride (FeCl3), magnesium chloride, ethylenediaminetetraacetic acid, and citric acid significantly decrease the α-amylase activity of saliva stains...

The term "vitamin D" refers to two chemical compounds - ergosterol, or vitamin D2, and cholecalciferol, or vitamin D3. Active vitamin D3 is correctly regarded as a neurohormone due to its pleiotropic biological activities. Although the relation between vitamin D and calcium-phosphorus metabolism has never been discussed, the knowledge on many other roles vitamin D plays is growing fast. Briefly, vitamin D immunomodulation includes attenuation and stimulation of Th1 and Th2 cell proliferation, respectively. Similarly, vitamin D can induce or inhibit the synthesis, secretion, and release of anti- inflammatory (IL-4 and IL-10) and pro-inflammatory (IL-1, TNF-α, IFN-γ) cytokines, respectively...
