The aging of the population is, currently, a major phenomenon, drawing the attention of a number of investigators. The significant increase of life expectancies over the past few decades, in addition to social and economic consequences, has lead to a major change in the morbidity and mortality profile of elders. Heart failure （HF） is a condition in which the heart can not pump enough blood to meet the body＇s needs. HF is predominantly a disorder of the elderly with rates increasing exponentially. The prevalence of HF approximately doubles with each decade of life. As people live longer, the occurrence of HF rises, as well as other conditions that complicate its treatment. Impaired heart function implies a reduced duration of survival. Fortunately, many factors that can prevent HF and improve outcome are known and can be applied at any stage. This review emphasizes the importance of factors inherent in aging itself, focusing on heart disease, particularly as a disease of aging, can help critically refine management of this acute and chronic disease, as well as foster preventive strategies to reduce the incidence of this common malady.

Meningococcal disease is the acute infection caused by Neisseria meningitidis, which has humans as the only natural host. The disease is widespread around the globe and is known for its epidemical potential and high rates of lethality and morbidity. The highest number of cases of the disease is registered in the semi-arid regions of sub-Saharan Africa. In Brazil, it is endemic with occasional outbreaks, epidemics and sporadic cases occurring throughout the year, especially in the winter. The major epidemics of the disease occurred in Brazil in the 70's caused by serogroups A and C. Serogroups B, C and Y represent the majority of cases in Europe, the Americas and Australia. However, there has been a growing increase in serogroup W in some areas. The pathogen transmission happens for respiratory route(droplets) and clinically can lead to meningitis and sepsis(meningococcemia). The treatment is made with antimicrobial and supportive care. For successful prevention, we have some measures like vaccination, chemoprophylaxis and droplets' precautions. In this review, we have described and clarify clinical features of the disease caused by N. meningitidis regarding its relevance for healthcare professionals.

AIM To compare the cannulation success, biochemical profile, and complications of the papillary fistulotomy technique vs catheter and guidewire standard *** From July 2010 to May 2017, patients were prospectively randomized into two groups: Cannulation with a catheter and guidewire(Group Ⅰ) and papillary fistulotomy(Group Ⅱ). Amylase, lipase and C-reactive protein at T0, as well as 12 h and 24 h after endoscopic retrograde cholangiopancreatography, and complications(pancreatitis, bleeding, perforation) were *** We included 102 patients(66 females and 36 males, mean age 59.11 ± 18.7 years). Group Ⅰ and Group Ⅱ had 51 patients each. The successful cannulation rates were 76.5% and 100%, respectively(P = 0.0002). Twelve patients(23.5%) in Group Ⅰ had a difficult cannulation and underwent fistulotomy, which led to successful secondary biliary access(Failure Group). The complication rate was 13.7%(2 perforations and 5 mild pancreatitis) vs 2.0%(1 patient with perforation and pancreatitis) in Groups Ⅰ and Ⅱ, respectively(P = 0.0597). CONCLUSION Papillary fistulotomy was more effective than guidewire cannulation, and it was associated with a lower profile of amylase and lipase. Complications were similar in both groups.

The regulation of plant transpiration is a key factor affecting transpiration efficiency, growth and adaptation of Eucalyptus species to limited water availability in tropical and subtropical environments. However, few studies have related this trait to the performance of Eucalyptus seedlings and none have investigated the influence of vapor pressure deficit (VPD) on transpiration rates and growth. In this study, the transpiration and growth responses of seedlings of Eucalyptus urophylla (S.T. Blake) and Eucalyptus cloeziana (F. Muell.) to progressive soil water deficits were evaluated under semi-controlled conditions using the fraction of transpirable soil water (FTSW) method. In addition, the influence of VPD on seedling transpiration, development and growth was also investigated. The FTSW threshold ranged from 0.40 to 0.99 for the transpiration rate and from 0.32 to 0.97 for the development and growth variables. Little or no changes in the FTSW threshold were detected in response to changes in atmospheric VPD. Both Eucalyptus species presented a conservation strategy under drought stress. In addition, water-conserving mechanisms during the seedling phase were related to rapid stomatal closure, reduced leaf area, and number of leaves.

AIM： To investigate the potential of bone marrow mononuclear cells （BM-MCs） in the regeneration of hepatic lesions induced by Schistosoma mansoni （***） chronic infection. METHODS： Female mice chronically infected with *** were treated with BM-MCs obtained from male green fluorescent protein （GFP） transgenic mice by intravenous or intralobular injections. Control mice received injections of saline in similar conditions, Enzyme-linked immunosorbent assay （ELISA） assay for transforming growth factor-beta （TGF-β）, polymerase chain reaction （PCR） for GFP DNA, immunofluorescence and morphometric studies were performed. RESULTS： Transplanted GFP^＋ cells migrated to granuloma areas and reduced the percentage of liver fibrosis. The presence of donor-derived cells was confirmed by Fluorescence in situ hybridization （FISH） analysis for detection of cells bearing Y chromosome and by PCR analysis for detection of GFP DNA. The levels of TGF-β, a cytokine associated with fibrosis deposition, in liver fragments of mice submitted to therapy were reduced. The number of oval cells in liver sections of ***-infected mice increased 3-4 fold after transplantation. A partial recovery in albumin expression, which is decreased upon infection with ***, was found in livers of infected mice after cellular therapy. CONCLUSION： In conclusion, transplanted BMCs migrate to and reduce the damage of chronic fibrotic liver lesions caused by ***.

Fractionation of rare earth elements（REE） and other trace metal concentrations（Th, U, Cd,Cr, Cu, Ni, Pb, and Zn） between mangrove sediments and claw muscles and shells of male crabs（Ucides cordatus） from a subtropical estuary highly impacted by fertilizer industry activities was investigated. This is the first record of REE distribution in these organisms,and the results showed higher accumulations of these metals, U and Th in shells, probably related to the replacement of Ca during molting. Contents of Cd, Cr and Ni were similar in both tissues, but Cu, Zn and Pb were mostly accumulated in the claw muscle with concentrations above those considered safe for human consumption according to the Brazilian legislation. REE fractionation was different in the analyzed tissues being softer in the shells. The results provided evidences that the water absorbed during molting controls the chemistry of REE in shells. In contrast, the chemistry of REE in the claw muscle, in which was observed preferential absorption of light REE, is controlled by diet. REE fractionation obtained for the claw muscles was closely correlated to the observed in the contaminated substrate and in materials related to the production of phosphate fertilizers（contamination source）, which supports their transference to this Ucides cordatus tissue without fractionation by the ingestion of sediments. Our results showed the potential use of crab tissues for monitoring REE and trace element sources in mangrove areas, with claw muscle exhibiting the contaminant source fingerprint.
