Damage recognition in nucleotide excision repair

The initial damage recognizing complex in bacterial nucleotide excision repair consists of two UvrA and two UvrB molecules. Of these proteins UvrB is the main damage recognition protein and is capable of recognizing various structurally unrelated types of damage. To do so, the protein must recognize a common alteration of the DNA structure induced by these different damages. For UvrB sterical hindrance of the present DNA modification prevents it from passing behind a _-hairpin structure present in the protein, thereby conferring damage recognition. Upon stalling of the protein at the site of damage in this way we show that two nucleotides become extrahelical: the nucleotide directly 3__ to the lesion and its base-pairing partner in the non-damaged strand. In contrast to other repair enzymes however the damaged nucleotide itself does not become extrahelical. Flipping in one of the two DNA strands has been shown to be important in preventing stable binding of the protein to undamaged DNA. Flipping in the other DNA strand however is required for efficient 3__ incision by UvrC, the nuclease of the system. A second incision at the 5__ side of the damage by the same protein facilitates removal of the damage-containing DNA oligonucleotide.UBL - phd migration 201

Post-Mortem Immunohistochemical Evidence of β2-Adrenergic Receptor Expression in the Adrenal Gland

The evidence from post-mortem biochemical studies conducted on cortisol and catecholamines suggest that analysis of the adrenal gland could provide useful information about its role in human pathophysiology and the stress response. Authors designed an immunohistochemical study on the expression of the adrenal β2-adrenergic receptor (β2-AR), a receptor with high-affinity for catecholamines, with the aim to show which zones it is expressed in and how its expression differs in relation to the cause of death. The immunohistochemical study was performed on adrenal glands obtained from 48 forensic autopsies of subjects that died as a result of different pathogenic mechanisms using a mouse monoclonal β2-AR antibody. The results show that immunoreactivity for β2-AR was observed in all adrenal zones. Furthermore, immunoreactivity for β2-AR has shown variation in the localization and intensity of different patterns in relation to the original cause of death. To the best of our knowledge, this is the first study that demonstrates β2-AR expression in the human cortex and provides suggestions on the possible involvement of β2-AR in human cortex hormonal stimulation. In conclusion, the authors provide a possible explanation for the observed differences in expression in relation to the cause of death

The effectiveness of long-term rehabilitation programmes

As the consequences of illicit drug use become more widespread amongst all sectors of our society, the relevance of long term rehabilitation continues to grow. A review of the literature reveals that although there has been considerable debate over the last decade surrounding the effectiveness of longterm rehabilitation, especially that involving residential TCs, research still predicts better outcomes for this treatment modality. This paper will explore some of the principle reasons why long-term rehabilitation has remained so effective. It will also examine how, 12 years after its inception, the Caritas New Hope Programme in Malta is evolving into a holistic and biopsychosocial project offering a range of services to drug users in rehabilitation.peer-reviewe

Critical sets of nonlinear Sturm-Liouville operators of Ambrosetti-Prodi type

The critical set C of the operator F:H^2_D([0,pi]) -> L^2([0,pi]) defined by F(u)=-u''+f(u) is studied. Here X:=H^2_D([0,pi]) stands for the set of functions that satisfy the Dirichlet boundary conditions and whose derivatives are in L^2([0,pi]). For generic nonlinearities f, C=\cup C_k decomposes into manifolds of codimension 1 in X. If f''0, the set C_j is shown to be non-empty if, and only if, -j^2 (the j-th eigenvalue of u -> u'') is in the range of f'. The critical components C_k are (topological) hyperplanes.Comment: 6 pages, no figure

Long-Term COVID: Case Report and Methodological Proposals for Return to Work

Almost two years after the beginning of the SARS-CoV-2 pandemic, the knowledge of which in the infectious and therapeutic spheres is constantly evolving, attention paid to the medicolegal aspects linked to this emergency phenomenon has mainly focused on the liability implications falling on healthcare personnel. With regard to the medicolegal assessment of the outcomes of COVID-19 illness, although it is a procedure that is commonly used, and although references in the assessment tables in force have been adhered to, a specific assessment protocol has not been standardized that takes into account, from an objective point of view, the degree of severity of the long-term residual outcomes and their impact on the social and working lives of subjects. This shortcoming appears to be attributable to the immediate need to categorize the results of COVID-19, but, in our opinion, it deserves an in-depth study and protocols to enable evaluation committees to draw up an assessment as precisely as possible and that is free of gaps, which could be the subject of legal disputes. The aim of the present work, in light of a worldwide problem, is to arrive at specific and univocal evaluation criteria for COVID-19 disease outcomes, applicable in different operational contexts of reemployment

Discriminação de diferentes tipos de pólvora por GC/MS e NIRS

Dissertação para obtenção do grau de Mestre no Instituto Universitário Egas MonizO trabalho que se segue consiste na discriminação de diferentes tipos de pólvora, com base em análises cromatográficas e espectroscópicas, e com o propósito de possibilitar a identificação de amostras de pólvora desconhecida, em contextos policiais e forenses. Estas análises foram efetuadas em 29 tipos de pólvora diferentes, provenientes das três marcas de fabricantes de pólvoras e munições mais comercializadas em Portugal, a Maxam (através da sua sucursal portuguesa, a Cacicambra), a Nobel Sports e a Baschieri & Pellagri. Para ambos os métodos foram utilizados três replicados de cada tipo de pólvora, perfazendo um total de 87 amostras. Esta investigação foi realizada em cooperação com o Centro Nacional de Peritagens, sediado no Departamento de Armas e Explosivos da Polícia de Segurança Pública de Lisboa. A análise química foi efetuada através de GC/MS, o solvente utilizado foi o diclorometano (DCM) e elaborou-se um perfil químico das pólvoras através dos seus cromatogramas, visualizando os diferentes picos cromatográficos e respetivas áreas, correspondentes às substâncias presentes em cada pólvora. A análise espectroscópica foi realizada através de NIRS. Foram efetuadas leituras diretamente nos grãos de pólvora e também na pólvora dissolvida em metil-etil-cetona (MEK). Os espectros foram obtidos através do Vision Spectral Analysis Software. Relativamente aos resultados, através da análise de GC/MS verificou-se a discriminação de 15 das 29 pólvoras, sendo que as restantes 14 apresentaram perfis químicos demasiado semelhantes para poderem ser diferenciados através desta técnica. A análise de NIRS na pólvora dissolvida em MEK revelou-se inconclusiva uma vez que o aparelho apenas conseguiu detetar a presença do solvente utilizado. Já a análise de NIRS dos grãos de pólvora permitiu construir, através dos dados dos espectros, um modelo estatístico capaz de discriminar corretamente todas as 29 pólvoras em estudo, sendo, por isso, a técnica mais robusta apresentada neste estudo
