Abstract
Globe-LFMC 2.0, an updated version of Globe-LFMC, is a comprehensive dataset of over 280,000 Live Fuel Moisture Content (LFMC) measurements. These measurements were gathered through field campaigns conducted in 15 countries spanning 47 years. In contrast to its prior version, Globe-LFMC 2.0 incorporates over 120,000 additional data entries, introduces more than 800 new sampling sites, and comprises LFMC values obtained from samples collected until the calendar year 2023. Each entry within the dataset provides essential information, including date, geographical coordinates, plant species, functional type, and, where available, topographical details. Moreover, the dataset encompasses insights into the sampling and weighing procedures, as well as information about land cover type and meteorological conditions at the time and location of each sampling event. Globe-LFMC 2.0 can facilitate advanced LFMC research, supporting studies on wildfire behaviour, physiological traits, ecological dynamics, and land surface modelling, whether remote sensing-based or otherwise. This dataset represents a valuable resource for researchers exploring the diverse LFMC aspects, contributing to the broader field of environmental and ecological research.

Abstract
This study aimed to analyse the added value of using ecotoxicological tools to complement and improve the assessment of natural water bodies status, in situations of climate change, with a higher frequency of extreme events as floods or droughts. Four water bodies of streams in the Guadiana Basin (Álamos, Amieira, Lucefécit, Zebro) were studied in 2017 and 2018 and classified based on the Water Framework Directive (WFD) parameters: Biological Quality Element - Phytobenthos (diatoms), General chemical and physicochemical elements, Specific pollutants, and Priority Substances. Complementarily, bioassays (including lethal and sublethal parameters) were carried out with organisms of different trophic levels: (i) the bacteria Aliivibrio fischeri; (ii) the microalgae Pseudokirchneriella subcapitata; (iii) the crustaceans Daphnia magna, Thamnocephalus platyurus and Heterocypris incongruens. A classification system with 5 scores was developed, permitting to classify water bodies from non-toxic (EC50 > 100 %; growth and feeding rate > 80 %; blue) to highly toxic (EC50 < 10 %; growth and feeding rate < 10 %; red). The comparison between the classification based on the WFD parameters and on ecotoxicological endpoints showed similar results for 71 % of the samples, and significant positive Pearson correlations were detected between the diatom-based Specific Polluosensitivity Index (SPI) and EC50V.fisheri, the algae growth rate and Shannon diversity index. These results indicate that when the biological quality elements cannot be used (namely under drought or flooding conditions) the application of ecotoxicological bioassays may be a good alternative. Further, when ecotoxicological parameters were included, an increase of worse classifications (Bad and Poor) was observed, revealing an improvement in the sensitivity of the classification, mainly in presence of specific and priority substances. So, the ecotoxicological analysis appears to provide useful information regarding the potential presence of both known and unknown contaminants at concentrations that cause biological effects (even within the WFD limits), in agreement with several authors that have already suggested its use in biomonitoring.

Abstract
Carbetocin or oxytocin are given routinely as first-line uterotonic drugs following delivery of the neonate during caesarean delivery to prevent postpartum haemorrhage. Low doses may be as effective as high doses with a potential reduction in adverse effects. In this double-blind, randomised, controlled, non-inferiority trial, we assigned low-risk patients undergoing elective caesarean delivery under spinal anaesthesia to one of four groups: carbetocin 20 μg; carbetocin 100 μg; oxytocin 0.5 IU bolus + infusion; and oxytocin 5 IU bolus + infusion. The study drug was given intravenously after delivery of the neonate. Uterine tone was assessed by the obstetrician 2, 5 and 10 minutes after study drug administration according to an 11-point verbal numerical rating scale (0 = atonic, 10 = excellent tone). The primary outcome measure was uterine tone 2 min after study drug administration. The pre-specified non-inferiority margin was 1.2 points on the 11-point scale. Secondary outcomes included uterine tone after 5 and 10 minutes, use of additional uterotonics, blood loss and adverse effects. Data were available for 277 patients. Carbetocin 20 μg resulting in uterine tone of (median (IQR [range])) 8 (7-8 [1-10]) was non-inferior to carbetocin 100 μg with tone 8 (7-9 [3-10]), median (95%CI) difference 0 (-0.44-0.44). Similarly, oxytocin 0.5 IU with tone 7 (6-8 [3-10]) was non-inferior to oxytocin 5 IU with tone 8 (6-8 [2-10]), median (95%CI) difference 1 (0.11-1.89). Carbetocin 20 μg was also non-inferior to oxytocin 5 IU, and oxytocin 0.5 IU was non-inferior to carbetocin 100 μg. Uterine tone after 5 and 10 minutes, use of additional uterotonics, blood loss and adverse effects were similar in all groups.

Abstract
OBJECTIVES This study aims to determine the prevalence of subclinical infectious agents considered core pathogens for worldwide screening in healthy, client-owned, indoor cats eligible to become blood donors in Spain and Portugal. MATERIALS AND METHODS Blood samples of healthy, indoor, domestic cats selected to be potential blood donors were tested for feline leukaemia virus antigens, feline immunodeficiency virus antibodies and polymerase chain reactions for Mycoplasma haemofelis, Candidatus Mycoplasma haemominutum, Candidatus Mycoplasma turicensis, feline leukaemia virus provirus, Leishmania spp. and Bartonella spp. Not all donors were tested for all agents. RESULTS Overall, 5105 healthy indoor cats were tested and 8.1% (414/5105) had at least one subclinical infectious agent that is transmissible through blood product transfusion. 1.5% (77/5105) were positive for feline leukaemia virus antigens and 2.9% (148/5105) were positive for feline immunodeficiency virus antibodies, therefore they were excluded as donors. The overall prevalence of haemoplasmas in feline leukaemia virus and feline immunodeficiency virus SNAP-negative feline blood donors was 3.7% (181/4880) [1.3% (63/4880) were positive for Mycoplasma haemofelis; 2.3% (112/4880) to Candidatus Mycoplasma haemominutum and 0.12% (6/4880) to Candidatus Mycoplasma turicensis]. The prevalence of feline leukaemia provirus was 5.2% (9/173) and of Bartonella spp. was 0.2% (2/1122). None of the 173 cats were positive for Leishmania spp. CLINICAL SIGNIFICANCE The prevalence of many transfusion transmissible pathogens was relatively high in this healthy, client-owned, indoor cats eligible to become blood donors. Performing an extended screening panel that includes at least polymerase chain reactions for Mycoplasma haemofelis, Candidatus Mycoplasma haemominutum, Candidatus Mycoplasma turicensis, feline leukaemia virus provirus, and Bartonella spp., in addition to feline leukaemia virus antigens and feline immunodeficiency virus antibodies, is recommended in pet blood banks from analogous regions.

Abstract
Abstract
Introduction Oxidative stress is the imbalance between reactive species produced in the body during metabolic reactions and antioxidant agents that have the ability to neutralize or prevent the formation of these species. One of the effects of oxidative stress is the normal and physiological process of cell aging that arises from the accumulation of tissue damage caused by free radicals.
Objectives To assess whether the activity of enzymes superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione reductase (GR) are influenced by the hydrotherapy sessions.
Methodology 37 subjects aged 60 years old and above, of both genders, were divided into two groups (experimental and control). The experimental group underwent 15 hydrotherapy sessions supervised by a physical therapist. Two peripheral venous blood samples were collected at two different times: T0, instant before the intervention and T1, instant after the last session. The activity of SOD, GPx and GR enzymes were determined, respectively, with the Ransod superoxide dismutase, Ransel glutathione peroxidase and glutathione reductase commercial kits, from Randox Laboratories Limited, United Kingdom. The assay was performed as described in the kits and the sample results were obtained by spectrophotometric reading.
Results SOD activity at T1 tended to decrease slightly compared to T0 (1437.64 ± 593.46 vs 1421.41 ± 705.39 U/g Hb). At T1, there was a statistically significant increase in GPx activity (48.14 ± 17.22 vs 57.72 ± 19.99 U/g Hb) and in GR activity (78.44 ± 21.26 vs 100.18 ± 30.85 U/L). Regarding gender, both genders tended to have higher values of GPx and GR at T1.
Conclusion According to the obtained results, we conclude that the practice of hydrotherapy presents as a positive stimulus in the antioxidant activity of aged individuals suggesting that a regular and moderate practice of exercise induces a higher quality of life.

Abstract
Stress, a well-known sculptor of brain plasticity, is shown to suppress hippocampal neurogenesis in the adult brain; yet, the underlying cellular mechanisms are poorly investigated. Previous studies have shown that chronic stress triggers hyperphosphorylation and accumulation of the cytoskeletal protein Tau, a process that may impair the cytoskeleton-regulating role(s) of this protein with impact on neuronal function. Here, we analyzed the role of Tau on stress-driven suppression of neurogenesis in the adult dentate gyrus (DG) using animals lacking Tau (Tau-knockout; Tau-KO) and wild-type (WT) littermates. Unlike WTs, Tau-KO animals exposed to chronic stress did not exhibit reduction in DG proliferating cells, neuroblasts and newborn neurons; however, newborn astrocytes were similarly decreased in both Tau-KO and WT mice. In addition, chronic stress reduced phosphoinositide 3-kinase (PI3K)/mammalian target of rapamycin (mTOR)/glycogen synthase kinase-3β (GSK3β)/β-catenin signaling, known to regulate cell survival and proliferation, in the DG of WT, but not Tau-KO, animals. These data establish Tau as a critical regulator of the cellular cascades underlying stress deficits on hippocampal neurogenesis in the adult brain.

Abstract
Depression is a prevalent psychiatric disorder with an increasing impact in global public health. However, a large proportion of patients treated with currently available antidepressant drugs fail to achieve remission. Recently, antipsychotic drugs have received approval for the treatment of antidepressant-resistant forms of major depression. The modulation of adult neuroplasticity, namely hippocampal neurogenesis and neuronal remodeling, has been considered to have a key role in the therapeutic effects of antidepressants. However, the impact of antipsychotic drugs on these neuroplastic mechanisms remains largely unexplored. In this study, an unpredictable chronic mild stress protocol was used to induce a depressive-like phenotype in rats. In the last 3 weeks of stress exposure, animals were treated with two different antipsychotics: haloperidol (a classical antipsychotic) and clozapine (an atypical antipsychotic). We demonstrated that clozapine improved both measures of depressive-like behavior (behavior despair and anhedonia), whereas haloperidol aggravated learned helplessness in the forced-swimming test and behavior flexibility in a cognitive task. Importantly, an upregulation of adult neurogenesis and neuronal survival was observed in animals treated with clozapine, whereas haloperidol promoted a downregulation of these processes. Furthermore, clozapine was able to re-establish the stress-induced impairments in neuronal structure and gene expression in the hippocampus and prefrontal cortex. These results demonstrate the modulation of adult neuroplasticity by antipsychotics in an animal model of depression, revealing that the atypical antipsychotic drug clozapine reverts the behavioral effects of chronic stress by improving adult neurogenesis, cell survival and neuronal reorganization.

Abstract
Depression is a highly prevalent and recurrent neuropsychiatric disorder associated with alterations in emotional and cognitive domains. Neuroplastic phenomena are increasingly considered central to the etiopathogenesis of and recovery from depression. Nevertheless, a high number of remitted patients experience recurrent episodes of depression, remaining unclear how previous episodes impact on behavior and neuroplasticity and/or whether modulation of neuroplasticity is important to prevent recurrent depression. Through re-exposure to an unpredictable chronic mild stress protocol in rats, we observed the re-appearance of emotional and cognitive deficits. Furthermore, treatment with the antidepressants fluoxetine and imipramine was effective to promote sustained reversion of a depressive-like phenotype; however, their differential impact on adult hippocampal neuroplasticity triggered a distinct response to stress re-exposure: while imipramine re-established hippocampal neurogenesis and neuronal dendritic arborization contributing to resilience to recurrent depressive-like behavior, stress re-exposure in fluoxetine-treated animals resulted in an overproduction of adult-born neurons along with neuronal atrophy of granule neurons, accounting for an increased susceptibility to recurrent behavioral changes typical of depression. Strikingly, cell proliferation arrest compromised the behavior resilience induced by imipramine and buffered the susceptibility to recurrent behavioral changes promoted by fluoxetine. This study shows that previous exposure to a depressive-like episode impacts on the behavioral and neuroanatomical changes triggered by subsequent re-exposure to similar experimental conditions and reveals that the proper control of adult hippocampal neuroplasticity triggered by antidepressants is essential to counteract recurrent depressive-like episodes.

Abstract
Depression during pregnancy has been associated with an increased risk of adverse outcomes for the infant such as preterm birth. These risks are not reduced with pharmacological treatment, but the effect of non-pharmacological therapies is unknown. We performed a systematic review to assess the risk of adverse perinatal outcomes in non-pharmacologically treated depressed women compared to non-depressed women. We found no studies that met our inclusion criteria, highlighting a critical need for research on this topic.

Abstract
Cognitive functioning can be differentially modulated by components of the immune system. Interferon-γ (IFNγ) is a pro-inflammatory cytokine whose production is altered in many conditions displaying some degree of cognitive deficits, although its role in cognitive functioning is still unclear. Here we show that the absence of IFNγ selectively enhances cognitive behaviours in tasks in which the hippocampus is implicated. Moreover, the absence of IFNγ leads to volumetric and cell density changes that are restricted to the dorsal part of the hippocampus. In the dorsal hippocampus, the absence of this pro-inflammatory cytokine leads to an increase in the numbers of newly born neurons in the subgranular zone of the dentate gyrus (DG), an adult neurogenic niche known to support learning and memory, and to an enlargement of the dendritic arborization of DG granule and cornu ammonis (CA)1 pyramidal neurons. Moreover, it also modestly impacts synaptic plasticity, by decreasing the paired-pulse facilitation in the Schaffer collateral to CA1 pyramidal cell synapses. Taken together, our results provide evidence that IFNγ is a negative regulator of hippocampal functioning, as its absence positively impacts on dorsal hippocampus structure, cell density, neuronal morphology and synaptic plasticity. Importantly, these neuroplastic changes are associated with improved performance in learning and memory tasks. Therefore, blockage of the IFNγ signalling may present as promising therapeutic targets for the treatment of inflammation-associated cognitive dysfunction.

Abstract
Current antidepressants must be administered for several weeks to produce therapeutic effects. We show that selective serotonin 2C (5-HT2C) antagonists exert antidepressant actions with a faster-onset (5 days) than that of current antidepressants (14 days) in mice. Subchronic (5 days) treatment with 5-HT2C antagonists induced antidepressant behavioral effects in the chronic forced swim test (cFST), chronic mild stress (CMS) paradigm and olfactory bulbectomy paradigm. This treatment regimen also induced classical markers of antidepressant action: activation of cAMP response element-binding protein (CREB) and induction of brain-derived neurotrophic factor (BDNF) in the medial prefrontal cortex (mPFC). None of these effects were induced by subchronic treatment with citalopram, a prototypical selective serotonin reuptake inhibitor (SSRI). Local infusion of 5-HT2C antagonists into the ventral tegmental area was sufficient to induce BDNF in the mPFC, and dopamine D1 receptor antagonist treatment blocked the antidepressant behavioral effects of 5-HT2C antagonists. 5-HT2C antagonists also activated mammalian target of rapamycin (mTOR) and eukaryotic elongation factor 2 (eEF2) in the mPFC, effects recently linked to rapid antidepressant action. Furthermore, 5-HT2C antagonists reversed CMS-induced atrophy of mPFC pyramidal neurons. Subchronic SSRI treatment, which does not induce antidepressant behavioral effects, also activated mTOR and eEF2 and reversed CMS-induced neuronal atrophy, indicating that these effects are not sufficient for antidepressant onset. Our findings reveal that 5-HT2C antagonists are putative fast-onset antidepressants, which act through enhancement of mesocortical dopaminergic signaling.

Abstract
AIM This work aims to develop receptor based alternatives to the conventional colloidal tracers in sentinel lymph node (SLN) detection. In this study, we report the detailed biological evaluation of two dextran pyrazolyl mannose derivatives towards this purpose. METHODS The dextran pyrazolyl mannose derivatives (DAPM4 and DAPM8) were labeled with the [99mTc(CO)3(H2O)3]+ core. In vitro saturation binding studies for the ligands were performed in mannose receptor-bearing RAW 264.7 macrophage precursor cells. Localization and pharmacokinetics studies of the tracers were conducted in normal Wistar rats with different ligand concentrations using in vivo activity distribution and scintigraphic imaging techniques. RESULTS The ligands were labeled with the [99mTc(CO)3)]+ core in high yield and radiochemical purity (>90%). DAPM4 and DAPM8 showed specific uptake in RAW 264.7 cells. In vivo localization studies showed concentration-dependent uptake and selective retention of the [99mTc]-labeled complexes of DAPM4 and DAPM8 in the sentinel node with highly favorable values of popliteal extraction [PE] (%PEDAPM4=92.94%,%PEDAPM8=91.80% at 180 min p.i.) and rapid clearance from the site of injection when administered at 50 µg/mL ligand concentration. CONCLUSION [99mTc(CO)3]-complexes of DAPM4 and DAPM8 show good in vivo potential to undergo further testing as agents for SLN detection in the clinic and their biological efficacy varies depending upon the concentration of ligands used for the procedure.

Abstract
BACKGROUND The limited supply of organs restricts the number of transplantations. Studying the families who refuse donation may help to increase the number of transplantations. METHODS This descriptive cross-sectional study used a questionnaire to obtain information from 61 family members who had refused to donate organs from January 1997 to December 2004. The exclusion criterion was donor death less than 1 year from the study. The mean age of subjects was 41 ± 12.7 years (range, 18 to 79 years) with 66% women. RESULTS More than half (36 of 69; 52%) of the families who refused donation would agree to donate in a new situation. The primary reasons for refusing donation were: disagreement among family members (25 of 128; 19%), lack of knowledge regarding the deceased's wishes (22 of 128; 17%), and previous request from the deceased not to be a donor (17 of 128; 13%). The most frequent suggestions to increase organ donation were to provide families with more information (43 of 149; 29%), initiate contact among the families (36 of 149; 24%), and involve a trusted physician (30 of 149; 20%). CONCLUSION Most family members who refused organ donation changed their minds and would agree to donate in a few situation. Most of the reasons for refusing to donate reflected a lack of information and discussion on the topic.

Abstract
Impairment of hippocampal neurogenesis has been associated with the expression of depressive-like symptoms and some studies have suggested neurogenesis as a critical factor in the normalization of behavior by antidepressant (AD) drugs. This study provides robust evidence that ongoing neurogenesis is essential for the maintenance of behavioral homeostasis and that its pharmacological arrest precipitates symptoms commonly found in depressed patients. Further, the incorporation of newly born neurons and astrocytes into the preexisting hippocampal neurocircuitry is shown to be necessary for the spontaneous recovery from the adverse effects of stress and for long-term benefits of AD treatments.

Abstract
The aim of the present study is to synthesize new mannosylated dextran derivative that can be labeled with Tc-99m for potential use in sentinel lymph node detection (SLND). The compound was designed to have a dextran with molecular weight of 10 kDa as a backbone, mannose for binding to mannose receptors of the lymph node and S-derivatized cysteine as a suitable chelator for labeling with [(99m)Tc(H(2)O)(3)(CO)(3)](+) precursor. Reaction of allyl bromide with dextran (MW 11800) yielded the intermediate allyl-dextran (1) with about 40% coupling. Addition of cysteine to allyl-dextran resulted in the S-derivatized cysteine, compound DC15 (2). The final product DCM20 (3) was obtained in good yield after in situ hydrolysis and activation of cyanomethyl tetraacetyl-1-thio-d-mannopyranoside and coupling to DC15. All derivatives were purified by ultrafiltration and characterized by NMR. DC15 and DCM20 were quantitatively labeled with (99m)Tc (>95% radiochemical purity) using the fac-[(99m)Tc(OH(2))(3)(CO)(3)](+) precursor and ligand concentration of 1.5 × 10(-6) M at neutral pH. Both (99m)Tc-labeled compounds (99m)Tc(CO)(3)-DC15 (6) and (99m)Tc(CO)(3)-DCM20 (7) remained stable after 6 h incubation at 37 °C in the presence of excess histidine or cysteine, as well as even after 20-fold dilution and incubation for 24 h at room temperature. The characterization of the compounds 6 and 7 was performed by comparing their HPLC radiochromatograms with those of their rhenium surrogates Re(CO)(3)-DC15 (4) and Re(CO)(3)-DCM20 (5) respectively that were prepared using the precursor [NEt(4)](2)fac-[ReBr(3)(CO)(3)] and characterized by IR and NMR spectroscopy. When injected subcutaneously from the foot pad of mice, (99m)Tc-labeled mannosylated dextran (7) showed accumulation in the popliteal lymph node (SLN in this model) higher than that of non-mannosylated analogue (6) and the (99m)Tc-phytate serving as standard. Compound 7 also exhibited lower radioactivity levels at the injection site compared to (99m)Tc-phytate. The SPECT/CT studies in mice confirmed that 7 accumulated in the popliteal lymph node allowing its clear visualization. The present findings demonstrate that compound 7 ((99m)Tc(CO)(3)-DCM20) is promising and merits further evaluation as a radiopharmaceutical for sentinel lymph node detection.

Abstract
BACKGROUND An epidemic of acute gastroenteritis occurred in Rio Branco City, Acre State, in Brazil's Amazon region in 2005. An investigation was conducted to confirm the etiology and identify possible risk factors for death. METHODS Rio Branco municipality surveillance data for the period May to October 2005 were reviewed. In a case-control study, children who died following acute gastroenteritis were compared to age-matched controls with acute gastroenteritis who survived. Rotavirus A (RV-A) was investigated in 799 stool samples and genotyped by reverse transcription polymerase chain reaction (RT-PCR). RESULTS The cumulative incidence of diarrhea in children aged <5 years was 21%. A fatal outcome was significantly associated with uncovered household water storage containers. RV-A was identified in 88% of samples and G9 was the prevalent genotype (71%). CONCLUSIONS Oral rehydration solution and boiling or chlorinating drinking water likely limited mortality. This epidemic was caused by RV-A genotype G9. After the outbreak, a rotavirus vaccine was introduced into the official childhood immunization schedule in Brazil.

Abstract
According to the WHO, 16-18 million people in Central and South America are infected by Trypanosoma cruzi. Chagasic achalasia affects between 7.1% and 10.6% of the population. The aim of this study was to evaluate the effects of Botox injections in the clinical response and esophageal function of patients with dysphagia due to chagasic achalasia. In total, 24 symptomatic patients with chagasic achalasia were randomly chosen to receive Botulinum Toxin (BT) or saline injected by endoscopy in the lower esophageal sphincter (LES). Patients were monitored with a clinical score of dysphagia and an objective assessment (esophagograms, scintillography, manometry, and nutritional assessment) for a period of 6 months. Clinical improvement of dysphagia was statistically significant (P < 0.001) in patients receiving BT when compared with the placebo. There was no significant difference in the placebo group regarding clinical score, LES basal pressure and esophageal emptying time. Esophageal emptying time in the toxin group was significantly lower than in the placebo (P=0.04) after 90 days. There were non-significant increases in esophageal emptying of 25.36% and 17.39%, respectively, at 90 and 180 days, in the BT group (P=0.266). Gender, age, and baseline LES pressure did not influence the response to BT. Our data strongly suggests that intrasphincteric injection of BT in LES is clinically effective in the treatment of chagasic achalasia.

Abstract
BACKGROUND Pancreatic pseudocyst endoscopic drainage has been described as a good treatment option, with morbidity and mortality rates that are lower than surgery. The aim of our study is to describe the efficacy of different forms of endoscopic drainage and estimate pseudocyst recurrence rate after short follow up period. PATIENTS AND METHODS We studied 30 patients with pancreatic pseudocyst that presented some indication for treatment: persistent abdominal pain, infection or cholestasis. Clinical evaluation was performed with a pain scale, 0 meaning absence of pain and 4 meaning continuous pain. Pseudocysts were first evaluated by abdominal CT scan, and after endoscopic retrograde pancreatography the patients were treated by transpapillary or transmural (cystduodenostomy or cystgastrostomy) drainage. Pseudocyst resolution was documented by serial CT scans. RESULTS 25/30 patients could be treated. Drainage was successful in 21 (70% in an 'intention to treat' basis). After a mean follow-up of 42 +/- 35.82 weeks, there was only 1 (4.2%) recurrence. A total of 6 complications occurred in 37 procedures (16.2%), and all but 2 were managed clinically and/or endoscopically: there was no mortality related to the procedure. Patients submitted to combined drainage needed more procedures than the other groups. There was no difference in the efficacy when we compared the three different drainage methods. CONCLUSIONS We concluded that pancreatic pseudocyst endoscopic drainage is possible in most patients, with high success rate and low morbidity.

Abstract
California shrubland wildfires are increasingly destructive, and it is widely held that the problem has been intensified by fire suppression, leading to larger, more intense wildfires. However, analysis of the California Statewide Fire History Database shows that, since 1910, fire frequency and area burned have not declined, and fire size has not increased. Fire rotation intervals have declined, and fire season has not changed, implying that fire intensity has not increased. Fire frequency and population density were correlated, and it is suggested that fire suppression plays a critical role in offsetting potential impacts of increased ignitions. Large fires were not dependent on old age classes of fuels, and it is thus unlikely that age class manipulation of fuels can prevent large fires. Expansion of the urban-wildland interface is a key factor in wildland fire destruction.

Abstract
BACKGROUND Upper gastrointestinal endoscopy has been reported as a risk factor for the transmission of Helicobacter pylori. The aim of this study was to evaluate the possibility of transmission of H. pylori infection by upper gastrointestinal endoscopy in patients who had previously had such procedures in a low disinfection level environment. METHODS The study included 1082 patients. Patients that had undergone upper gastrointestinal endoscopy or were treated with antibiotics 15 days before the index endoscopy were excluded. H. pylori infection was diagnosed by ultra-rapid urease test. Variables analyzed were age, gender, type of dyspepsia (organic or functional), and the number of previous upper gastrointestinal endoscopies. RESULTS Overall prevalence of H. pylori infection was 60%. Patients ranged in age from 13 to 94 years (mean = 45.8, SD = 15.7) and the number of previous upper gastrointestinal endoscopies ranged from 0 to 20 (mean = 1.5, SD = 2.4). In 53.3% of the patients, upper gastrointestinal endoscopy revealed some mucosal lesion (organic dyspepsia). Prevalence of H. pylori infection was higher in patients with organic rather than functional dyspepsia (71.1% vs. 47.1%, p < 0.001). There was no statistically significant difference in the mean number of upper gastrointestinal endoscopies in patients with and without H. pylori infection. CONCLUSIONS We concluded that there was no association between history of upper gastrointestinal endoscopy and current H. pylori infection in this study population.

Abstract
Helicobacter pylori is a Gram negative bacteria that colonizes gastric epithelial cells. It has been associated with several gastric disease including chronic gastritis and peptic ulcer. Helicobacter pylori infection diagnosis can be done with invasive and non-invasive methods. In invasive methods an endoscopic gastric mucosa biopsy specimen is used. In our study we compare the sensitivity, specificity, costs and applicability of four invasive diagnostic tests: culture, urease ultra-rapid test, histology (Giemsa and Hematoxilineosin stain) and fuchsin stained mucosal slides. Urease test was the easiest, fastest diagnostic test, with sensitivity of 86% and specificity of 100%, being also the cheapest test. We concluded that it should be the test of choice for Helicobacter pylori infection diagnosis.

Abstract
BACKGROUND Esophageal band ligation is considered to be as efficient as endoscopic sclerotherapy, with a lower complication rate, including bacteremia. There are few studies comparing the two methods. The aim of this study was to compare the incidence of bacteremia after both treatments in patients with portal hypertension secondary to schistosomiasis. METHODS Endoscopic sclerotherapy and band ligation were performed using standard techniques. Blood samples were obtained 5 and 30 minutes after endoscopic band ligation or sclerotherapy and cultured for aerobic and anaerobic organisms. RESULTS In the sclerotherapy group 2 of 43 (4.6%) blood cultures were positive (Peptostreptococcus sp and Streptococcus mitis). A similar result was obtained in the band ligation group: 2 of 35 (5.7%) had positive cultures, both with Staphylococcus aureus. CONCLUSIONS There is no difference in the frequency of bacteremia after treatment of esophageal varices with endoscopic sclerotherapy or endoscopic band ligation in patients with portal hypertension secondary to schistosomiasis.

Abstract
Previous pathological reports have indicated that swollen and vacuolated motoneuron cell bodies are the most predominant feature characterising Wobbler mouse motoneuron disease, but there has been little supportive evidence using area measurements. The present study focuses on the possible role of changes in neuronal nuclear and perikaryal volumes in the cervical spinal cord ventral horn, using new and traditional stereological probes which provide unbiased estimates of volume. Semithin sections from the ventral horn of Wobbler mice and age and sex-matched phenotypically normal littermates were examined at 2 ages (young and old). The young Wobbler group had significantly larger volume weighted mean perikaryal volumes compared with age-matched controls, reflecting the presence of large swollen cells characteristic of this group; this situation was reversed in the control group. Number-weighted perikaryal volume estimates in the old Wobbler group were smaller than in age-matched controls. The variation in perikaryal volume was greatest in the young Wobbler group in which the coefficient of variation was 127%. The mean number weighted and volume weighted mean nuclear volumes were significantly smaller in the old Wobbler group compared with age-matched controls and young Wobbler groups. The application of new stereological probes has enabled us to document more precisely these changes in neuronal structure in the Wobbler mutant mouse.

Abstract
Biliary and pancreatic stents are effective tools in the management of obstructive jaundice (both malignant and benign), pancreatic pseudocyst drainage, and as treatment for biliary and pancreatic fistulae. Unfortunately, stents may become blocked and require replacement in a number of patients. In the present study a blocked stent from a patient with transpapillary drainage of pancreatic pseudocyst and another from a patient with obstructive jaundice resulting from cancer of the head of the pancreas associated with Mirizzi syndrome were characterized by electron microscopy. Stent blockage was diagnosed by a pressure test and stent cultures were performed. Electron microscopy of the blocked stents revealed the sludge to consist of microcolonies of bacteria mixed with amorphous material, and cultures of both stents were positive for Klebsiella sp and E. coli.

Abstract
Quantification of silver-stained nucleolar organiser regions (AgNORs) in paraffin sections may provide clues about the proliferation and differentiation in normal and neoplastic tissues. The aim of the present investigation was to determine whether AgNOR quantification could provide useful data about proliferation in the different segments of the normal human colorectal crypt. Samples of histologically 'normal' large intestine (n = 8) were obtained from colorectal cancer resections at a distance of > 5 cm from the tumour margins and were routinely processed for paraffin embedding using strictly standardised procedures. Sections were cut and stained with a one-stage silver colloid impregnation technique. The longitudinally sectioned crypts were divided into proliferative (P), intermediate (I) and surface (S) segments using strict criteria. Clearly defined AgNORs, which appeared as black dots within the nuclear profile, were quantified from each segment for volume density (Vv) and number per unit area (NA) estimates using traditional point-counting techniques. A 1-way analysis of variance followed by Scheffe's test indicated significant progressive reductions of AgNOR Vv and NA from P to S segments. Our data suggest that both volume and frequency of AgNORs may be related to cellular proliferation since both parameters are highest in the P segment. The further exploitation of stereological tools in conjunction with AgNOR staining may be valuable in assessing normal differentiation and proliferation patterns and in predicting the biological behaviour of neoplastic tissues in which increased proliferation is a feature.

Abstract
Endoscopy therapy of pancreatic pseudocyst has been described as an efficient method. We report six cases of pancreatic pseudocyst treated by pancreatic stenting (three cases), cystogastrostomy (three cases) and cystoduodenostomy (one case). Rapid symptomatic improvement and pseudocyst regression were noted in all cases, except one. Such patient needed pancreatic stenting even after cystogastrostomy due to main pancreatic duct stenosis. There were three complications: hemorrhage (one case) and pseudocyst infection (two cases), and all were treated clinically. Two patients had pseudocyst infection previous to endoscopic manipulation, and they were treated only with antibiotics and endoscopic drainage, without surgery (treatment suggested by most of the authors). We concluded that endoscopic therapy of pancreatic pseudocyst is efficient and safe, being responsible for rapid relief of symptoms in most of patients.
