Abstract:

The hippocampus is a brain structure known to be important for learning and memory, more specifically for the acquisition of spatial information. Hebb (1940) suggested that storage of information in the brain may involve modifications in the strength of synaptic connections. One example of an artificially-induced synaptic alteration that may share common mechanisms with memory formation is long-term synaptic enhancement (LTE). Recently, behaviorally-induced changes in hippocampal synapses have been discovered to occur in conjunction with exploratory behavior. This type of change has been calle

Abstract:

The persistence of Salmonella spp. in low moisture foods is a challenge for the food industry as despite control strategies already in place, notable outbreaks still occur. The aim of this study was to characterise isolates of Salmonella, known to be persistent in the food manufacturing environment, by comparing their microbiological characteristics with a panel of matched clinical and veterinary isolates. The gross morphology of the challenge panel was phenotypically characterised in terms of cellular size, shape and motility. In all the parameters measured, the factory isolates were indistin

Abstract:

Previous studies reveal decreases in hippocampal interneuron cell densities during normal aging. However, considerable variation in results exists within the literature. Overall, interneuron populations show either decreases or conservation in cell numbers expressing calcium binding proteins parvalbumin (PV) and calbindin (CB), and neuropeptides somatostatin (SOM) and neuropeptite Y (NPY) in hippocampal subregions of CA1, CA3, dentate granule cell layer, and dentate hilus. Notably, only few of the past aging studies showed correlations in cell loss with behavioral impairments in aged animals.

Ethoxyresorufin deethylase activity (EROD), a measurement of CYP1A activity, was also inhibited by sulforaphane (100 M) but was not competitive, and a preincubation time-dependence was observed.

Abstract:

Heterosis is defined as the superiority in performance of heterozygous genotypes compared to their corresponding genetically different homozygous parents. This phenomenon is already known since the beginning of the last century and it has been widely used in plant breeding, but the underlying genetic and molecular mechanisms are not well understood. In this work, a systems biological approach based on molecular network structures is proposed to contribute to the understanding of heterosis.

Abstract:

Development of novel approaches for the direct immunomodulation of allogeneic donor cells would have significant utility in tissue transplantation. Immunocamouflage of cell surfaces by covalently grafted methoxypoly(ethylene glycol) (mPEG; PEGylation) has emerged as a promising approach. While previous studies demonstrated the in vitro and in vivo efficacy of immunocamouflaged allogeneic cells and viruses, the biophysical mechanisms of immunoprotection have not been well-defined due to the labile nature of biological samples.

Abstract:

The biological basis of the clinical heterogeneity in Parkinson's Disease (PD) is unclear. It is likely to involve complex interactions between genetic and environmental factors and between a range of pathological processes, including protein homeostasis and immune system function. Microglial activation in the brain and peripheral innate immune changes are known to occur in PD. Recently genetic, animal and cellular studies have linked several innate immune related genes and proteins (e.g. HLADR, TREM2, TLR2, TLR4, caspase-1) to PD and provided evidence that they may have a role in PD pathogene

Purpose: Sodium fluorescein ('fluorescein') is the most commonly used diagnostic ophthalmic dye for clinical assessment of the ocular surface. An increase in fluorescein staining presents after the use of certain multi-purpose solutions (MPS) and contact lenses, which is a clinical phenomenon known as solution induced corneal staining (SICS). The clinical relevance and mechanisms underpinning fluorescein staining however is conflicting in the literature.

Attention refers to the cognitive processes that prioritise a subset of available sensory information for enhanced processing, and which can be directed towards spatial locations, object features, time, or other aspects of the environment.

Despite some great success, many human diseases cannot be effectively treated, prevented or cured, yet. Moreover, prescribed drugs are often not very efficient and cause undesired side effects.

Abstract:

Mestrado em Biologia Molecular e Celular<br>A compreensão da base molecular da variação fenotípica observada dentro e entre espécies, como acontece na longevidade, é um dos principais objetivos da Biologia. Em Drosophila melanogaster foram já identificados mais de 50 genes que podem contribuir para a definição do tempo de vida. Contudo, na maioria dos estudos, as conclusões são baseadas em mutações criadas artificialmente noa genes alvo. Desta forma, é improvável que o tipo de variação observada exista em populações naturais, e como tal não se encontra totalmente esclarecido se variação nestes

Abstract:

Digenetic trematodes are a common pest problem in aquaculture where their unappetizing appearance often reduces the marketability of food fish. Aquatic snails are intermediate hosts in the trematode lifecycle and are commonly targeted with control measures to prevent the crop fish from becoming infected. I evaluated several chemical and biological snail control strategies as alternatives to the potentially invasive black carp. Copper sulfate, hydrated lime slurry, and several fish and decapod species were tested for effectiveness against physid (Physa spp.) and planorbid (Helisoma spp.) snails

Abstract:

Nef is an HIV -1 accessory protein with a fundamental role for virus replication in vivo and for the development of AIDS. Among its several activities, Nef is essential for full HIV-1 infectivity, a function highly prominent in lymphoid cells. So far, the mechanism by which Nef promotes HIV-1 infectivity has remained elusive. Over the course of 3 years, my PhD research activity has led to the identification of the host transmembrane protein SERINC5, and to a lesser extent SERINC3, as potent inhibitors of HIV-1 infectivity counteracted by the viral protein Nef [Rosa et al., 2015]. SERINC5 is pr
