A qualidade do servi?o no armazenamento dos alimentos na Institui??o Escolar Centro Educacional Edvardo Toscano no munic?pio de Guarabira-PB

A Administra??o P?blica ? considerada um conjunto de atividades ligadas ao Estado e direcionadas ? sociedade, tendo como finalidade suprir as necessidades da popula??o. Dessa forma, a excel?ncia do n?vel de servi?o de uma gest?o p?blica pode ser analisada a partir da efici?ncia, da efic?cia e da efetividade, podendo assim, observar se a gest?o est? realizando uma boa ger?ncia. A alimenta??o ? parte inerente ? Administra??o P?blica. Pois, a legisla??o vigente determina que os estudantes de escolas p?blicas t?m direito a se alimentarem no per?odo em que se encontram na escola. Logo, a alimenta??o ? alvo de estudos, normas e fiscaliza??es perante o poder p?blico. Diante disso, este estudo tem como objetivo verificar se o local de estoque e armazenagem do Centro Educacional Edvardo Toscano est? sendo utilizado de acordo com as normas vigentes, e, em especial, de acordo com a RDC n? 216/2004, de tal forma a refletir, consequentemente, bons servi?os para a sociedade. A pesquisa-a??o foi a metodologia realizada para fazer a pesquisa e os dados foram analisados a partir da pesquisa qualitativa, pois, esta tinha a finalidade de observar como est?o sendo guardados os alimentos in natura. Os estudos apontaram que de modo geral os alimentos est?o sendo bem armazenados. Contudo, algumas situa??es s?o motivos para interfer?ncia imediata, porque n?o atendem as normas vigentes, tais como, a presen?a de um cart?o protetor para a janela, em vez de uma tela; a presen?a de uma caixa de medicamentos e a inexist?ncia de circula??o de ar, que interfere diretamente nos produtos armazenados na institui??

Biomarkers and in vitro strategies for nephrotoxicity and renal disease assessment

Acute kidney injury (AKI) is a global public health concern, impacting nearly 13.3 million patients and resulting in three million deaths per year. Chronic kidney disease has increased by 135% since 1990, representing the pathology with the fastest growth rate worldwide. The annual costs of dialysis and kidney transplants range between US$35,000 and US$100,000 per patient. Despite its great impact, kidney disease has remained mostly asymptomatic for many years. AKI continues to be a major, unmet medical condition for which there are no pharmacological treatments available, while animal models are limited to provide direction for therapeutic translation into humans. Currently, serum creatinine is the standard biomarker to identify nephrotoxicity; however, it is a late stage biomarker. Hence, there is a pressing need to study in vitro biomarkers for the assessment of nephrotoxicity in order to develop new and safer drugs. Understanding of the mechanisms by which molecules produce nephrotoxicity is vital in order to both prevent adversity and treat kidney injury. In this review, we address new technologies and models that may be used to identify earlier biomarkers and pathways involved in nephrotoxicity, such as cell culture, omics, bioinformatics platform, CRISPR/Cas9 genome-editing, in silico, organoids and 3D bioprinting, considering AOP

Contribution of microscopy for understanding the mechanism of action against trypanosomatids

Transmission electron microscopy (TEM) has proved to be a useful tool to study the ultrastructural alterations and the target organelles of new antitrypanosomatid drugs. Thus, it has been observed that sesquiterpene lactones induce diverse ultrastructural alterations in both T. cruzi and Leishmania spp., such as cytoplasmic vacuolization, appearance of multilamellar structures, condensation of nuclear DNA, and, in some cases, an important accumulation of lipid vacuoles. This accumulation could be related to apoptotic events. Some of the sesquiterpene lactones (e.g., psilostachyin) have also been demonstrated to cause an intense mitochondrial swelling accompanied by a visible kinetoplast deformation as well as the appearance of multivesicular bodies. This mitochondrial swelling could be related to the generation of oxidative stress and associated to alterations in the ergosterol metabolism. The appearance of multilamellar structures and multiple kinetoplasts and flagella induced by the sesquiterpene lactone psilostachyin C indicates that this compound would act at the parasite cell cycle level, in an intermediate stage between kinetoplast segregation and nuclear division. In turn, the diterpene lactone icetexane has proved to induce the external membrane budding on T. cruzi together with an apparent disorganization of the pericellar cytoskeleton. Thus, ultrastructural TEM studies allow elucidating the possible mechanisms and the subsequent identification of molecular targets for the action of natural compounds on trypanosomatids.Fil: Lozano, Esteban Sebastián.

Cytotoxic T cells and mycobacteria

How the immune system kills Mycobacterium tuberculosis is still a puzzle. the classical picture of killing due to phagocytosis by activated macrophages may be only partly correct. Based on recent evidence, we express here the view that cytotoxic T lymphocytes also make an important contribution and suggest that DNA vaccines might be a good way to enhance this.

Natural archives of long-range transported contamination at the remote lake Letšeng-la Letsie, Maloti Mountains, Lesotho

Naturally accumulating archives, such as lake sediments and wetland peats, in remote areas may be used to identify the scale and rates of atmospherically deposited pollutant inputs to natural ecosystems. Co-located lake sediment and wetland cores were collected from Letšeng-la Letsie, a remote lake in the Maloti Mountains of southern Lesotho. The cores were radiometrically dated and analysed for a suite of contaminants including trace metals and metalloids (Hg, Pb, Cu, Ni, Zn, As), fly-ash particles, stable nitrogen isotopes, polycyclic aromatic hydrocarbons (PAHs) and persistent organic pollutants such as polychlorinated biphenyls (PCBs), polybrominated flame retardants (PBDEs) and hexachlorobenzene (HCB). While most trace metals showed no recent enrichment, mercury, fly-ash particles, high molecular weight PAHs and total PCBs showed low but increasing levels of contamination since c.1970, likely the result of long-range transport from coal combustion and other industrial sources in the Highveld region of South Africa. However, back-trajectory analysis revealed that atmospheric transport from this region to southern Lesotho is infrequent and the scale of contamination is low. To our knowledge, these data represent the first palaeolimnological records and the first trace contaminant data for Lesotho, and one of the first multi-pollutant historical records for southern Africa. They therefore provide a baseline for future regional assessments in the context of continued coal combustion in South Africa through to the mid-21st century

Mindfulness-based interventions in epilepsy: a systematic review

Mindfulness based interventions (MBIs) are increasingly used to help patients cope with physical and mental long-term conditions (LTCs). Epilepsy is associated with a range of mental and physical comorbidities that have a detrimental effect on quality of life (QOL), but it is not clear whether MBIs can help. We systematically reviewed the literature to determine the effectiveness of MBIs in people with epilepsy. Medline, Cochrane Central Register of Controlled Trials, EMBASE, CINAHL, Allied and Complimentary Medicine Database, and PsychInfo were searched in March 2016. These databases were searched using a combination of subject headings where available and keywords in the title and abstracts. We also searched the reference lists of related reviews. Study quality was assessed using the Cochrane Collaboration risk of bias tool. Three randomised controlled trials (RCTs) with a total of 231 participants were included. The interventions were tested in the USA (n = 171) and China (Hong Kong) (n = 60). Significant improvements were reported in depression symptoms, quality of life, anxiety, and depression knowledge and skills. Two of the included studies were assessed as being at unclear/high risk of bias - with randomisation and allocation procedures, as well as adverse events and reasons for drop-outs poorly reported. There was no reporting on intervention costs/benefits or how they affected health service utilisation. This systematic review found limited evidence for the effectiveness of MBIs in epilepsy, however preliminary evidence suggests it may lead to some improvement in anxiety, depression and quality of life. Further trials with larger sample sizes, active control groups and longer follow-ups are needed before the evidence for MBIs in epilepsy can be conclusively determined
