Abstract
The striatal glutamatergic hyperactivity is considered critical in the development of levodopa-induced dyskinesias (LID) in Parkinson's disease (PD). Pharmacological antagonism of the metabotropic glutamate receptors (mGluRs), in particular, the subtype mGluR5, can inhibit the expression of dyskinesia in both rodent and nonhuman primate models of PD. However, the exact mechanisms underlying the mGluR5 antagonism effects are not completely known. The vesicular glutamate transporters (VGluts) are localized in the synaptic vesicles of the striatal glutamatergic axonal terminals. The effects of mGluR5 antagonism modulating VGlut1 and VGlut2, as selective markers for the corticostriatal and thalamostriatal pathways, respectively, are still unknown. We investigated the effects of the mGluR5 antagonist, 2-methyl-6-(phenylethynyl) pyridine (MPEP) on the striatal expression of VGlut1 and VGlut2 in levodopa-treated hemiparkinsonian rats. Male Sprague-Dawley rats received a unilateral 6-hydroxydopamine (6-OHDA) administration in the nigrostriatal pathway. Rats were treated with: (a) levodopa (12 mg/kg/day with benserazide 15 mg/kg, ip) + vehicle; (b) MPEP (1.5 mg/kg/day, ip) + vehicle; (c) levodopa + MPEP, or (d) saline for 10 days. Levodopa treatment induced dyskinesias and did not modify the striatal expression of either VGlut1 or VGlut2. The administration of MPEP significantly attenuated LID and decreased the levels of VGlut2, but not the VGlut1, in the striatum ipsilateral to the lesion (P < 0.05). Our results suggest that the effects of MPEP on LID might be mediated by a modulating effect on VGlut 2 expression.

Abstract
OBJECTIVE To compare the percentage of patients who were able to bypass the postoperative intensive care recovery unit after selective spinal anesthesia with lidocaine-fentanyl versus levobupivacaine-fentanyl for anorectal surgery in jackknife position. MATERIAL AND METHODS Randomized double-blind clinical trial comparing 2 groups of 30 patients classified ASA 1-2. One group received 18 mg of 0.6% lidocaine plus 10 microg of fentanyl while the other group received 3 mg of 0.1% levobupivacaine plus 10 microg of fentanyl. Intraoperative variables were time of start of surgery, maximum extension of sensory blockade, requirement for rescue analgesics, and hemodynamic events. The level of sensory blockade was recorded at 5, 10, and 15 minutes after the start of surgery and at the end of the procedure. The degrees of postoperative motor blockade and proprioception were recorded, as were the results of the Romberg test and whether or not the patient was able to bypass the postoperative recovery unit. Also noted were times of start of ambulation and discharge, complications, and postoperative satisfaction. RESULTS Intraoperative variables did not differ significantly between groups, and all patients in both groups bypassed the postoperative recovery unit. Times until walking and discharge home, complications, and overall satisfaction after surgery were similar in the 2 groups. CONCLUSIONS Both spinal anesthetic solutions provide effective, selective anesthesia and are associated with similar rates of recovery care unit bypass after anorectal surgery in jackknife position.

Abstract
There are no data about the influence of tracheostomy in the incidence of catheter-related bloodstream infection (CRBSI) on the catheterization of the jugular vein by posterior access and there are no recommendations relating to this circumstance in the guidelines of the Centers for Disease Control and Prevention (CDC) and of Healthcare Epidemiology of America/Infectious Diseases Society of America (SHEA/IDSA) for the prevention of CRBSI. The novel finding of this observational study was that there was a higher incidence of CRBSI in the catheterization of jugular vein by posterior access in patients with tracheostomy than without it (13.24 vs 0 episodes of CRBSI per 1,000 catheter-day; odds ratio = 23.92; 95% CI = 1.86-infinite; p = 0.008). Thus, the presence of tracheostomy is a risk factor of CRBSI on the catheterization of jugular vein by posterior access.

Abstract
This paper presents an analysis of the relationships between technology of water point, management related practices and functionality over time through an extensive water point mapping study made in 15 rural districts of Tanzania, which covered 15% of the total rural population of the country. Results show irregular functionality rates at district level by technology, but reveal statistical dependence between functionality and technology at regional level. Management-related questions show that reported expenditure is the indicator most related to functionality. All categories of water points show very low performance over time. In the first five years of operation, about 30% of water points become non-functional. Only between 35% and 47% of water points are working 15 years after installation, depending on the technology. By categories, hand pumps are the less durable of the technologies studied. We suggest that more emphasis has to be placed on the creation of community capacities to manage the services during and after the installation of water points. At the same time, the role of decentralised government has to be strengthened to provide support to community services in the long term.

Abstract
Guidelines for the prevention of catheter-related bloodstream infection (CRBSI) recommend subclavian rather than femoral venous access to minimize the risk of CRBSI. However, they do not address the issue of CRBSI with subclavian venous access in the presence of tracheostomy, where the incidence of CRBSI has been found to be higher than without tracheostomy. In this study, we found lower CRBSI in subclavian venous access in the presence of tracheostomy than in femoral venous access (3.9 vs. 10.1 CRBSI per 1000 catheter-days; odds ratio = 0.39; 95% confidence interval ≤0.001-0.91; p 0.03).

Abstract
Dietary interventions have been proposed as a way to increase lifespan and improve health. The senescence-accelerated prone 8 (SAMP8) mice have a shorter lifespan and show alterations in the central nervous system. Moreover, this mouse strain shows decreased sirtuin 1 protein expression and elevated expression of the acetylated targets NFkappaB and FoxO1, which are implicated in transcriptional control of key genes in cell proliferation and cell survival, in reference to control strain, SAMR1. After eight weeks of intermittent fasting, sirtuin 1 protein expression was recovered in SAMP8. This recovery was accompanied by a reduction in the two acetylated targets. Furthermore, SAMP8 showed a lower protein expression of BDNF and HSP70 while intermittent fasting re-established normal values. The activation of JNK and FoxO1 was also reduced in SAMP8 mice subjected to an IF regimen, compared with control SAMP8. Our findings provide new insights into the participation of sirtuin 1 in ageing and point to a potential novel application of this enzyme to prevent frailty due to ageing processes in the brain.

Abstract
Epilepsy is a common disease affecting between 1% and 2% of the general population. The incidence increases with age. Given the complicated etiology and pathogenesis of this disease, epileptic patients of all ages may require anesthesia. The perioperative care of these patients involves a number of special considerations, although the main issues to deal with are pharmacologic. This review gives an overview of the etiopathogenesis and pathophysiology of epilepsy and describes the general characteristics of antiepileptic drug therapy. The anesthetic implications of chronic treatment with antiepileptic agents and the interactions between these drugs and common anesthetics are discussed in more detail.

Abstract
Purification and characterisation of pepper (Capsicum annuum L) chloroplasts and chromoplasts isolated from commercial green, red and yellow mature fruits were undertaken. Induction of the synthesis of several antioxidants in organelles isolated from mature fruits was found. The ultrastructure of organelles and the presence and activity of SOD isozymes and enzymes involved in the ASC-GSH cycle, together with the non-enzymatic antioxidant content and some oxidative parameters, were analysed. It was found that lipids, rather than proteins, seem to be a target for oxidation in the chromoplasts. The ascorbate and glutathione contents were elicited during differentiation of chloroplasts into chromoplasts in both red and yellow fruits. The activity of SOD and of components of the ASC-GSH cycle was up-regulated, suggesting that these enzymes may play a role in the protection of plastids and could act as modulators of signal molecules such as O(2) ( -) and H(2)O(2) during fruit maturation. The presence of an Mn-SOD in chromoplasts isolated from yellow pepper fruits was also investigated in terms of structural and antioxidant differences between the two cultivars.
