La vit. D, o calcitriolo, è stata identificata inizialmente nei primi anni '20 ed ha un ruolo chiave nella regolazione del metabolismo osseo, nell'omeostasi del calcio e del fosforo e nel promuovere la mineralizzazione ossea. Le azioni della vit. D sono mediante tramite un recettore nucleare (VDR), che è espresso in numerosi organi come l'intestino, l'osso e il rene, ma anche nelle gonadi, nel seno, nel pancreas, nel sistema cardiovascolare, nel cervello (microglia) e nelle cellule del sistema immunitario...

Background: The accuracy of zero coronary calcium score as a filter in patients with chest pain has been demonstrated at the emergency room and outpatient clinics, populations with low prevalence of coronary artery disease (CAD). Objective: To test the gatekeeping role of zero calcium score in patients with chest pain admitted to the coronary care unit (CCU), where the pretest probability of CAD is higher than that of other populations. Methods: Patients underwent computed tomography for calcium scoring, and obstructive CAD was defined by a minimum 70% stenosis on invasive angiography...

The structure elucidation of heavy Grignard reagents (RAeX, Ae=Ca, Sr, and Ba, X=halides) has been greatly strived after, mainly because of their inaccessibility and remarkable instability. The synthesis of a series of butadienylcalcium compounds is presented, including 1-calcio-4-lithio-1,3-butadiene, 1,4-dicalcio-1,3-butadiene, and a Ca4 [O] inverse crown ether complex, via the reaction between 1,4-dilithio-1,3-butadienes and calcium iodide in THF. Single-crystal X-ray analysis of these unprecedented heavy Grignard reagents revealed unique structural characteristics and bonding modes...

A number of influencing factors mean that the random substitution of cyclodextrins (CD) in solution is difficult to reproduce. Reaction assembly in mechanochemistry reduces the number of these factors. However, lack of water can improve the reaction outcomes by minimizing the reagent's hydrolysis. High-energy ball milling is an efficient, green and simple method for one-step reactions and usually reduces degradation and byproduct formation. Anionic CD derivatives have successfully been synthesized in the solid state, using a planetary ball mill...

Introducción: la gestación y lactancia están relacionadas con pérdidas temporales en la densidad mineral ósea (DMO) materna. Una suplementación con calcio podría resultar beneficiosa para evitar la pérdida de masa ósea del esqueleto materno. Otros nutrientes como los prebióticos han sido identificados como responsables de un incremento en la absorción de minerales, pudiendo condicionar la mineralización ósea.Objetivo: estudiar el efecto de la suplementación de la dieta materna con el prebiótico inulina enriquecida con oligofructosa, durante la gestación y la lactancia sobre el contenido mineral óseo (CMO) y la DMO al final del periodo de lactancia...

Introduction: Secondary hyperparathyroidism (SHPT) is a consequence of chronic kidney disease. The treatment at the Brazilian Unified Heath System (SUS) is performed with calcitriol, a drug which favors hypercalcemia and/or hyperphosphatemia, hindering the control of SHPT. Another option is paricalcitol, which causes parathormone (PTH) suppression faster than calcitriol, with minor changes in calcium-phosphorus product and calcium and phosphorus serum levels. Objective: This study aims to develop a cost-effectiveness analysis of paricalcitol versus calcitriol for patients in dialytic treatment with SHPT, from the SUS perspective...

Introduction: The persistence of mineral metabolism disorders after renal transplant (RT) appears to possess a negative impact over graft and patient's survival. Objectives: To evaluate the parameters of mineral metabolism and the persistence of hyperparathyroidism (HPT) in transplanted patients for a 12-month period after the procedure. Methods: Retrospective analysis of 41 transplants (18 women- 44%, mean age of 39 ± 15 years) performed in a University Hospital, evaluating changes of calcium (Ca), phosphorus (P) and parathyroid hormone (PTH) and the prevalence of persistent HPT...

Calcium (Ca) is the most abundant mineral element in our body. It accounts for about 2% of body weight. The functions of calcium are: a) functions skeletal and b) regulatory functions. Bone consists of a protein matrix that mineralizes mainly with calcium (the most abundant), phosphate and magnesium, for it is essential an adequate dietary intake of Ca, phosphorus and vitamin D. The ionic Ca (Ca2+) is essential to maintain and / or perform different specialized functions of, virtually, all body cells cellular...

Pregnancy is a challenge from the nutritional point of view, because nutrient requirements are increased and alter its intake can affect maternal and fetal health. Micronutrient defi ciency states are related to preeclampsia, intrauterine growth restriction, abortion and congenital anomalies. Currently, the diet of many expectant mothers is insufficient in micronutrients, in this cases supplementation is necessary. It is recommended supplementation with folic acid in doses of 400 mcg / day and 5 mg/day in risk pregnant, and should begin at least one month before conception and during the first 12 weeks gestation, and extend it throughout pregnancy in mothers with nutritional risk...

Introducción: la esofagitis eosinofílica (EEo) es una enfermedad inmunoalérgica crónica emergente en adultos. Surge como respuesta disfuncional frente a los antígenos de los alimentos y se caracteriza por síntomas recurrentes de disfunción esofágica e inflamación. El tratamiento farmacológico y dietético se basa en su patogénesis y debe ser individualizado. Uno de los posibles abordajes dietéticos se basa en la eliminación empírica de alimentos que con mayor frecuencia causan EEo.Objetivo: evaluar la ingesta dietética de los pacientes con EEo que siguen la dieta de exclusión de los seis grupos de alimentos (DESGA) y conocer sus posibles carencias nutricionales...

Half the patients with coronary artery disease present with sudden death - or acute infarction as first symptom, making early diagnosis pivotal. Myocardial perfusion scintigraphy is frequently used in the assessment of these patients, but it does not detect the disease without flow restriction, exposes the patient to high levels of radiation and is costly. On the other hand, with less radiological exposure, calcium score is directly correlated to the presence and extension of coronary atherosclerosis, and also to the risk of cardiovascular events...

Nutritional and metabolic complications can develop after Roux-en-Y gastric bypass (RYGB) when there is an exaggerated response to the anatomical and functional changes or when there is inadequate nutritional supplementation. Severe malnutrition is rare, but deficiencies of vitamin B12, iron, calcium and thiamin, metabolic bone disease and gallstones are common after RYGB. Shortage of vitamin B12, iron, calcium and also cholelithiasis are caused at least partially by excluding the duodenum and proximal jejunum from food transit...

This paper reports the application of ultrasound in the semi-hydrogenation of alkynes over two novel Pd/Boehmite catalysts. The semi-hydrogenations of phenylacetylene, diphenylacetylene and 2-butyne-1,4-diol have either been investigated in an ultrasonic bath under atmospheric hydrogen pressure, or in an ultrasonic horn reactor under 0.1-0.5MPa hydrogen pressure. Alkyne hydrogenation was suppressed by sonication under atmospheric hydrogen pressure, but promoted by sonication under 0.1MPa of hydrogen pressure...
