RESUMEN

BACKGROUND AND AIM: Epilepsy is one of the most common chronic neurological disorders with a high prevalence. Epileptic people and their family members suffer more from social stigma than the disorder itself. Among various complex reasons knowledge and awareness about epilepsy are the two important factors underlying discriminatory attitudes towards epileptic people. Community pharmacists play a major role in the care of these patients. In this study we mainly aimed to gain insights into the knowledge and awareness of and attitudes (AKA) towards epilepsy both in epileptic and healthy individuals in an urban community. To this end we also aimed at developing a reliable and valid measurement tool to assess AKA levels. MATERIALS AND METHODS: This study was conducted in 13 community pharmacies with 219 respondents. Factor analysis yielded three clear subscales. RESULTS: It was found that a vast majority of the participants were familiar with epilepsy; yet only 18 of them had detailed information. The community pharmacists were indicated as a main source of information about epilepsy at the same rate to that of physicians. Although most of the respondents knew that epilepsy was not a form of mental illness only about one forth of them knew the real cause. More than half of the respondents supported the epileptics' socialization in the community. CONCLUSION: We believe that the questionnaire developed in the study is a promising instrument for determining educational needs and offering guidance to healthcare professionals in developing standardized educational tools and programs.

RESUMEN

BACKGROUND AND OBJECTIVE: The anaesthetic method for intracranial neurosurgery must provide haemodynamic stability on emergence and allow early evaluation of the neurological status. In this study, we examined the effects of the alpha-2 agonist dexmedetomidine given at the end of the procedure to prevent hyperdynamic responses during extubation and to allow a comfortable and high-quality recovery. METHODS: Forty ASA I-III patients, aged between 18 and 75 yr, having elective intracranial surgery, were divided into two random groups. Standard procedures and drugs were used for monitoring, induction and maintenance. Isoflurane was reduced by 50% 5 min before the end of the surgery, and in Group I dexmedetomidine 0.5 microg kg(-1) and in Group II 20 mL of 0.9% NaCl were administrated intravenously over 60 s. Systolic, diastolic and mean arterial pressures, and heart rate were recorded before intravenous administration and also at 1, 3 and 5 min after administration, 1 min before extubation, during extubation, 1, 3, 5, 10, 15, 20 and 30 min after extubation. Duration of extubation and recovery were noted, and the quality of extubation was evaluated on a 5-point scale. RESULTS: Mean arterial pressure and heart rate were significantly higher in Group II than in Group I (P < 0.01). There were no statistically significant differences between groups regarding the duration of extubation and recovery (P > 0.05). Extubation quality score of all the patients were 1 in Group I and in Group II, the quality scores were 1 for 35%, 2 for 45% and 3 for 20% of the patients (P < 0.001). None of the patients in Group I and Group II showed respiratory depression, nausea or vomiting. CONCLUSION: Without interfering in recovery time, dexmedetomidine 0.5 microg kg(-1) administered 5 min before the end of surgery stabilizes haemodynamics, allows easy extubation, provides a more comfortable recovery and early neurological examination following intracranial operations.

RESUMEN

PURPOSE: The true incidence of pregnancy related carpal tunnel syndrome (PRCTS) is unknown. Most of the diagnoses of PRCTS are made based only on clinical symptoms. Here, we report a prospective controlled clinical trial assessing the electrophysiological changes in pregnant women to provide objective measure of the median nerve function. METHODS: Pregnant women in the third trimester (n=69) and age-matched non-pregnant women (n=40) asymptomatic for CTS were included in the study. Nerve conduction studies of the median and ulnar nerves across the carpal tunnel were bilaterally performed with the standard techniques. RESULTS: All the median sensory nerve conduction studies (amplitude, latency and velocity) performed from the ring finger and palmar region to wrist showed significant prolongation of median nerve conduction in the pregnant women compared with the control group (*p

RESUMEN

AIMS: The goal of this study was to identify a marine algae-associated bacterium isolated from Laminaria japonica and investigate this microorganism's growth-promoting effects on plants. METHODS AND RESULTS: The bacterium, identified as Pseudoalteromonas porphyrae, was determined to display a biostimulatory activity for seed germination and shoot growth in several agricultural plants and also for growth in ginseng callus cell culture. This biostimulatory activity was linked to a catalase enzyme that was excreted in the maximal amount during the transition from logarithmic growth phase to stationary growth phase. In addition, selected shifts in growth temperature and medium salinity affected the amount of enzyme excreted. The purified catalase was determined to be composed of identical subunits. The catalase of interest displayed significantly higher biostimulatory activity than the catalase from bovine liver. CONCLUSIONS: The catalase investigated in this study is unique in that it promotes growth in and possibly contributes to stress tolerance of plants. SIGNIFICANCE AND IMPACT OF THE STUDY: The catalase of interest has the potential for use in treatments that aim to improve percent seed germination as well as obtaining tall shoots in a shorter time period.

RESUMEN

A sanitized cheese plant was swabbed for the presence of nonstarter lactic acid bacteria (NSLAB) biofilms. Swabs were analyzed to determine the sources and microorganisms responsible for contamination. In pilot plant experiments, cheese vats filled with standard cheese milk (lactose:protein = 1.47) and ultrafiltered cheese milk (lactose:protein = 1.23) were inoculated with Lactococcus lactis ssp. cremoris starter culture (8 log cfu/mL) with or without Lactobacillus curvatus or Pediococci acidilactici as adjunct cultures (2 log cfu/mL). Cheddar cheeses were aged at 7.2 or 10 degrees C for 168 d. The raw milk silo, ultrafiltration unit, cheddaring belt, and cheese tower had NSLAB biofilms ranging from 2 to 4 log cfu/100 cm2. The population of Lb. curvatus reached 8 log cfu/g, whereas P. acidilactici reached 7 log cfu/g of experimental Cheddar cheese in 14 d. Higher NSLAB counts were observed in the first 14 d of aging in cheese stored at 10 degrees C compared with that stored at 7.2 degrees C. However, microbial counts decreased more quickly in Cheddar cheeses aged at 10 degrees C compared with 7.2 degrees C after 28 d. In cheeses without specific adjunct cultures (Lb. curvatus or P. acidilactici), calcium lactate crystals were not observed within 168 d. However, crystals were observed after only 56 d in cheeses containing Lb. curvatus, which also had increased concentration of D(-)-lactic acid compared with control cheeses. Our research shows that low levels of contamination with certain NSLAB can result in calcium lactate crystals, regardless of lactose:protein ratio.

RESUMEN

The role of nitric oxide (NO) in childhood bacterial meningitis was investigated by determining the levels of nitrate/nitrite, stable end products of NO metabolism, in cerebrospinal fluid (CSF). Eighteen children with bacterial meningitis and 18 as a control group were included in the study. Mean (+/- SD) CSF nitrate/nitrite levels were 27.6 +/- 26 micromol/l in the bacterial meningitis group and 3.2 +/- 1.8 micromol/l in the control group (p = 0.0005). We found no correlation between CSF nitrate/nitrite levels and CSF white blood cell count (r = 0.22), protein (r = 0.26) or tumour necrosis factor alpha (TNF-alpha) levels (r = 0.046), but a moderate negative correlation between CSF nitrate/nitrite and glucose levels (r = -0.46).

RESUMEN

A dipeptidase with prolinase activity from Lactobacillus helveticus CNRZ32, which was designated PepR, was purified to gel electrophoretic homogeneity and characterized. The NH2-terminal amino acid sequence of the purified protein had 96% identity to the deduced NH2-terminal amino acid sequence of the pepR gene, which was previously designated pepPN, from L. helveticus CNRZ32. The purified enzyme hydrolyzed Pro-Met, Thr-Leu, and Ser-Phe as well as dipeptides containing neutral, nonpolar amino acid residues at the amino terminus. Purified PepR was determined to have a molecular mass of 125 kDa with subunits of 33 kDa. The isoelectric point of the enzyme was determined to be 4.5. The optimal reaction conditions, as determined with Pro-Leu as substrate, were pH 6.0 to 6.5 and 45 to 50 degrees C. The purified PepR had a Km of 4.9 to 5.2 mM and a Vmax of 260 to 270 mumol of protein per min/mg at pH 6.5 and 37 degrees C. The activity of purified PepR was inhibited by Zn2+ but not by other cations or cysteine, serine, aspartic, or metal-containing protease inhibitors or reducing agents. Results obtained by site-directed mutagenesis indicated that PepR is a serine-dependent protease. Gene replacement was employed to construct a PepR-deficient derivative of CNRZ32. This mutant did not differ from the wild-type strain in its ability to acidify milk. However, the PepR-deficient construct was determined to have reduced dipeptidase activity compared to the wild-type strain with all dipeptide substrates examined.

RESUMEN

Lactobacillus helveticus CNRZ32 possesses an Xaa-prolyldipeptidyl aminopeptidase (PepX), which releases amino-terminal dipeptides from peptides containing proline residues in the penultimate position. The PepX gene, designated pepX, from Lb. helveticus CNRZ32 was sequenced. Analysis of the sequence identified a putative 2379-bp pepX open-reading frame, which encodes a polypeptide of 793 amino acid residues with a deduced molecular mass of 88,111 Da. The gene shows significant sequence identity with sequenced pepX genes from lactic acid bacteria. The product of the gene contains a motif that is almost identical with the active-site motif of the serine-dependent PepX from lactococci. The introduction of pepX into Lactococcus lactis LM0230 on either pGK12 (a low-copy-number plasmid vector) or pIL253 (a high-copy-number plasmid vector) did not result in a significant increase in PepX activity, while the introduction of pepX into CNRZ32 on pGK12 resulted in a four-fold increase in PepX activity. Southern hybridization experiments revealed that the pepX gene from CNRZ32 is well conserved in lactobacilli, pediococci and streptococci. The physiological role of PepX during growth in lactobacillus MRS (a rich medium containing protein hydrolysates along with other ingredients) and milk was examined by comparing growth of CNRZ32 and a CNRZ32 PepX-negative derivative. No difference in growth rate or acid production was observed between CNRZ32 and its PepX-negative derivative in MRS. However, the CNRZ32 PepX-negative derivative grew in milk at a reduced specific growth rate when compared to wild-type CNRZ32. Introduction of the cloned PepX determinant into the CNRZ32 PepX-negative derivative resulted in a construct with a specific growth rate similar to that of wild-type CNRZ32.
