Profili neuropsicologici nei bambini pretermine con basso peso alla nascita
2004
AIM: Several studies focus on the psychic development of extremely low birth weight (ELBW) preterm infants and highlight the presence of neurological, cognitive and relating disorders. Several contributions have in fact shown that in these subjects in school age disturbances of cognitive functions may be encountered; in particular, disturbances of specific neuropsychological functions, such as attention defects, impaired visuo-spatial function, memory and language have been reported in subjects with a globally normal intelligence quotient. METHODS: Forty-three school-aged children were studied (21 males and 22 females). They had a low birth weight (weight between 1,050-2,450 g), the gestati…
Proyectos en fuga. Preludio para asignaturas multidisciplinares en la formación de profesorado
2013
This paper relates a teaching and research experience in a subject taught during 2011-12 at the University of Valencia. It reports the context of the subject within the curriculum of the Faculty of Education. It tells the relationship between educational resources used and the circumstances of teaching and educational organization. Exposes and comments on resources from the different areas of knowledge involved ineducational planning. Analyzes, through photographic documentation, how resources were worked. Discusses how the students applied the resources to end projects working in collaborative groups. Reflect on the main difficulties encountered by both the students and the team of teacher…
Association between residential proximity to environmental pollution sources and childhood renal tumors
2016
FI=3.835 (año 2016), Q1 Background: Few risk factors for childhood renal tumors are well established. While a small fraction of cases might be attributable to susceptibility genes and congenital anomalies, the role of environmental factors needs to be assessed. Objectives: To explore the possible association between residential proximity to environmental pollution sources (industrial and urban areas, and agricultural crops) and childhood renal cancer, taking into account industrial groups and toxic substances released. Methods: We conducted a population-based case-control study of childhood renal cancer in Spain, including 213 incident cases gathered from the Spanish Registry of Childhood T…
Internalizing symptoms in children affected by childhood absence epilepsy: A preliminary study
2016
Introduction: Childhood absence epilepsy (CAE) is a common type of pediatric idiopathic generalized epilepsy, characterized by multiple seizures of typical absence, with typical EEG pattern consisting in bilateral synchronous and symmetrical discharges of generalized 3 Hz spike-wave (SWDs). Recently, some researchers have suggested that the underlying epileptogenic mechanism of absence seizures selectively involves the frontal cortical circuits, also supported by video-electroencephalography data(3). These data may be considered as a new window in CAE comprehension and management, particularly about symptoms different from seizure that children affected may present. In this light, aim of th…
I bambini di famiglie omoparentali: valutazione dello sviluppo psicologico e sessuale
2005
In the last few years some studies have been made about homosexual parenthood and especially if this interferes with the child's development, identity and future sexual tendency. These studies prove that the parents' homosexuality does not seem to compromise the child's psychosexual development and that the child's possible homosexuality does not depend on the parents' sexual behaviour but on different factors linked to the relationship; as a matter of fact there are no relevant differences in the occurrence of homosexuality in children born from homosexual and hereosexual parents. The present study investigated the psychological and sexual development in a group of children of homoparental…

Simultaneous analysis of lysine, Nɛ-carboxymethyllysine and lysinoalanine from proteins
2007
Protein quality was assayed by simultaneous measurement of lysine (Lys), carboxymethyllysine (CML) and lysinoalanine (LAL). GC-FID analysis of N-tert-butyl dimethylsilyl (tBDMSi) derivatives of these amino acids was undertaken. tBDMSi derivates were separated on a CP-SIL 5CB commercially fused silica capillary column (25 m × 0.25 mm i.d., 0.25 μm film thickness) employing a thermal gradient programmed from 200 to 300 °C. The identity of tBDMSi derivatives of Lys, CML and LAL was established by GC–MS while FID detection was employed for quantification. Analytical parameters such as linearity (lysine 350–4200 μM, LAL 3–81 μM, CML 16–172 μM), precision (1–13% variation coefficients), accuracy …
Review: Determination of Vitamin D in Dairy Products by High Performance Liquid Chromatography
2005
This work reviews the methods used for the determination of vitamin D in some dairy products (milk and infant formulas) by high performance liquid chromatography (HPLC). The low vitamin D contents and the presence of interfering compounds require sample treatment and purification of the extract. The advantages and drawbacks of hot and cold saponification, direct extraction and different types of extract purification are also discussed, taking into account the lack of vitamin D stability by heating, exposure to light and oxidation. With respect to chromatographic determination, the mode (normal or reverse phase), type of column (microcolumn or conventional) and detection system (UV, electro…
High-performance liquid chromatographic determination of furfural compounds in infant formulas
2002
Furfural contents in adapted and follow-up infant formulas were measured by RP-HPLC. The evolution of furfural compound contents during storage (a year at 20 and 37 °C) was studied. 2-Furylmethylketone and 5-methyl-2-furaldehyde were not detectable in analysed samples. The differences in the furfural compounds at point zero between both infant formulas has to be ascribed to the differences in protein and iron contents. An increase in free 5-hydroxymethyl-2-furfuraldehyde (HMF), 2-furaldehyde (F) and HMF+F contents was observed in all samples, although the differences were not statistically significant. The storage temperature affected the total HMF content and the storage time affected the …
Stability of tocopherols in adapted milk-based infant formulas during storage
2004
Abstract An evaluation is made of the effects of added α -tocopherol ( α -T) or α -tocopherol acetate ( α -TAc) combined with iron lactate or sulfate, storage time (up to 17 months) and storage temperature (22°C and 37°C) on the α -TAc, α -T, γ -tocopherol ( γ -T) and δ -tocopherol ( δ -T) content of infant formulas. Tocopherols were measured by normal phase HPLC and fluorescence detection after direct extraction, which allows the determination of both α -TAc and α -T. The α -TAc content was not affected by temperature or storage time, although the α -, γ - and δ -T contents, which were lower at 37°C than at 22°C, were significantly affected. The type of iron salt added (lactate or sulfate)…
