Abstract
Dietary factors may influence the process of atherosclerosis and coronary artery calcification (CAC). This study assessed CAC and its association with dietary intake in asymptomatic men. We evaluated 150 asymptomatic men with mean age of 58.2±5.3 years. The dietary intake was assessed by the Food Consumption Register method. CAC was measured through multidetector computed tomography (MDCT) and assessed in accordance with the Agatston score. Modified Poisson regression model was used to estimate the effects of intake of different nutrients that are prevalent in moderate/severe CAC, adjusted for calorie intake and CAC risk factors by means of prevalence ratios and 95% confidence intervals [95%CI]. An association was found between the intake of some nutrients and moderate/severe CAC. Lower carbohydrate intake (P=0.021) and higher lipid intake (P=0.006) were associated with moderate/severe CAC. After adjustment, the nutrients associated with the prevalence of moderate/severe CAC were carbohydrates (P=0.040), lipids (P=0.005), and saturated fatty acids (SFA) (P=0.013). A 1% increase in lipids and SFA intake caused an increase of 4% [95%CI: 1-7%] and 8% [95%CI: 2-14%] in the prevalence of moderate/severe CAC, respectively. A 1% increase of carbohydrate intake led to a 2% decrease in the likelihood of moderate/severe CAC [95%CI: 1-4%]. These conclusions showed that the higher intake of total lipids and SFA was associated with higher CAC scores, whereas higher carbohydrate intake was associated with lower CAC scores in asymptomatic men.

Abstract
We analyzed the clinicopathological, immunohistochemical and cytogenetic features of 106 extranodal (EN) diffuse large B-cell lymphomas (DLBCLs) from stomach (34 cases), intestine (10), cervico-cephalic region (11), central nervous system (13), testes (21), skin (8), and miscellaneous sites (9). Hans' algorithm and the immunohistochemical double expressor score (DES) for MYC and BCL2 were applied to all cases. A subset of fifty-eight cases were analyzed with fluorescent in situ hybridization (FISH) with specific break apart probes for BCL6, MYC, BCL2, CCND1, BCL10 and MALT1 genes. Clinical records were available for all patients. The immunohistochemical study showed that, in our series of EN-DLBCLs, the Hans' subgroup and the DES differed significantly according to the site of origin. At FISH analysis, BCL6 and BCL2 were the most commonly rearranged genes in non-GC and in GC cases, respectively. Gastrointestinal lymphomas displayed the highest rate of gene rearrangements, often with MYC involvement. One testicular DLBCL showed BCL2/MYC double hit. At survival analysis, cerebral and testicular origin was associated with poor prognosis. In addition, Hans' subgroup and other immunohistochemical markers influenced patients' outcome. In conclusion, our data suggest that immunophenotypic, genetic and survival characteristics of EN-DLBCL are related to the specific primary site of the disease.

Abstract
OBJECTIVE To describe the short-term outcome of critically ill HIV-infected children with access to highly active antiretroviral therapy (HAART) in a developing region. METHODS Prospective observational study conducted in a paediatric teaching hospital in Cape Town, South Africa. All children admitted to the paediatric intensive care unit (PICU) with suspected HIV infection were screened. Data are n (%) with 95% confidence intervals. RESULTS Sixty eight of 96 HIV antibody-positive children, median age 3 months, were confirmed HIV-infected. Predicted PICU mortality was 0.42. Fifty one children (75%; 95% CI 65 to 85%) survived to PICU discharge, but hospital survival was only 51% (95% CI 40 to 63%). Limitation of intervention (LOI) decisions were a factor in the majority of PICU and ward deaths. Twenty one PICU survivors (31%; 95% CI 20 to 42%) commenced HAART, and two children were already on treatment. Nineteen children (28%) were considered to be established on HAART after 1 month. Thirteen HIV-infected children (19%; 95% CI 10 to 28%), representing 25% (95% CI 14 to 37%) of all PICU survivors, and 68% (95% CI 48 to 89%) of those PICU survivors who were established on HAART remain well on treatment after median 350 days. CONCLUSION The majority of HIV-infected children survived to discharge from PICU, but only half survived to hospital discharge. LOI decisions, usually made in PICU, directly influenced short-term survival and the opportunity to commence HAART. Although few critically ill HIV-infected children survived to become established on HAART, the long-term outcome of children on HAART is encouraging and warrants further investigation.

Abstract
Organotellurides are important intermediates in organic synthesis and, consequently, the occupational exposure to them is a constant risk for laboratory workers. These compounds can elicit many neurotoxic events in the central nervous system (CNS) that are associated with several neurological symptoms. In contrast, organoselenium compounds are considered to exert neuroprotective actions on such effects. Neurofilaments (NF) are important cytoskeletal proteins and phosphorylation/dephosphorylation of NF is important to stabilize the cytoskeleton. In this work we investigated the potential protective ability of the selenium compounds ebselen and diphenyl diselenide (PhSe)(2) against the effect of diphenyl ditelluride (PhTe)(2) and methylmercury (MeHg) on the total (phosphorylated plus nonphosphorylated) and phosphorylated immunocontent of the high molecular weight neurofilament subunit (NF-H) from slices of cerebral cortex of 17-day-old rats. We observed that 1muM MeHg induced hyperphosphorylation, increasing the total immunocontent of this subunit of the high-salt Triton insoluble NF-H. Otherwise, 15muM (PhTe)(2) induced hyperphosphorylation of the high-salt Triton insoluble NF-H without altering the total immunocontent of this protein into the cytoskeletal fraction. Concerning the selenium compounds, 15muM (PhSe)(2) and 5muM ebselen did not induce alteration per se on the in vitro phosphorylation of NF-H. In addition, (PhSe)(2) and ebselen at these concentrations, presented a protective effect against the action of (PhTe)(2) and MeHg, on the immunoreactivity of NF-H. Considering that hyperphosphorylation of NF-H is associated with neuronal dysfunction it is probable that the effects of (PhTe)(2) and MeHg could be related to the remarkable neurotoxicity of these organocalcogenides. Furthermore the neuroprotective action of selenium compounds against (PhTe)(2) and MeHg effects could be a promising route to be exploited for a possible treatment of calcogenides poisoning.

Abstract
Propionic and methylmalonic acidemias are inherited neurometabolic disorders biochemically characterized by tissue accumulation of propionic (PA) and methylmalonic (MMA) acids, respectively. Neurofilaments (NF) are important cytoskeletal proteins and phosphorylation/dephosphorylation of NF is important to stabilize the cytoskeleton. We investigated the effects of PA and MMA on the high molecular weight neurofilament subunit associated with the cytoskeletal fraction of rat cerebral cortex along development. Cortical slices from 9- to 60-day-old rats were incubated with 2.5 mM PA or MMA. The cytoskeletal fraction was extracted and the immunoreactivity for phosphorylated or total NF-H was analyzed by immunoblotting using specific antibodies. Results showed that treatment of tissue slices with the acids induced an increased Triton-insoluble phosphorylated NF-H immunoreactivity in up to 17-day-old rats. Furthermore, treatments significantly increased the total amount of NF-H in 12-day-old rats. These findings indicate that PA and MMA alter the dynamic regulation of NF-H assembly in the cytoskeletal fraction.

Abstract
In this study we investigated the effects of the branched chain alpha-ketoacids accumulating in maple syrup urine disease (MSUD) on the concentrations of the high molecular weight neurofilament subunit (NF-H) associated with the cytoskeletal fraction of the cerebral cortex of 12-day-old rats. Cortical slices were incubated with alpha-ketoisocaproic acid (KIC), alpha-keto beta-methylvaleric acid (KMV) and alpha-ketoisovaleric acid (KIV) at concentrations ranging from 0.5 to 1.0 mM. The cytoskeletal fraction was extracted and the immunoreactivity for phosphorylated and total NF-H was analyzed by immunoblotting. The in vitro 32P incorporation into NF-H was also determined. Results showed that treatment of tissue slices induced with KMV increased Triton-insoluble phosphorylated NF-H immunoreactivity, with no alteration in total NF-H immunoreactivity. Furthermore, KIC treatment drastically increased the total amount of NF-H, whereas KIV did not change either phosphorylated or total NF-H immunoreactivity. KMV also increased the in vitro 32P incorporation into NF-H, confirming the highly phosphorylated NF-H levels detected in the immunoblot. These findings demonstrate that KIC and KMV alter the dynamic regulation of NF-H assembly in the cytoskeletal fraction. Therefore we may suggest that cytoskeletal disorganization may be one of the factors associated with the neurodegeneration characteristic of MSUD disease.
