Obtaining from grape pomace an enzymatic extract with anti-inflammatory properties

Grape pomace, a winemaking industry by-product, is a rich source of bioactive dietary compounds. Using proteases we have developed an enzymatic process for obtaining a water-soluble extract (GP-EE) that contains biomolecules such as peptides, carbohydrates, lipids and polyphenols in soluble form. Of especial interest is its high polyphenol content (12 %), of which 77 % are flavonoids and 33 % are phenolic acids. The present study evaluates in vitro the potential anti-inflammatory effect of GP-EE by monitoring the expression of inflammatory molecules on N13 microglia cells stimulated with lipopolysaccharide (LPS). GP-EE decreases the mRNA levels of the inflammatory molecules studied. The molecules under study were as follows: inducible nitric oxide synthase (iNOS), tumor necrosis factor- α (TNF-α), interleukin-1β (IL-1β), the ionized calcium binding adaptor molecule-1(Iba-1) and the Toll like receptor-4 (TLR-4), as well as the iNOS protein level in LPS-stimulated microglia. Our findings suggest that, as a result of its ability to regulate excessive microglial activation, GP-EE possesses antiinflammatory properties. Therefore, acting as a chemopreventive agent, it may be of therapeutic interest in neurodegenerative diseases involving neuroinflammation. We can, therefore, propose GP-EE as a useful natural extract and one that would be beneficial to apply in the field of functional food

"Flooding our eyes with rubbish": urban waste management in Maputo, Mozambique

Critical voices on urban management tend to portray conflicting governmentalities, with western 'top-down' municipal development models on the one hand, and the everyday practices and diffuse forms of power of the poor majority on the other. This paper takes solid waste (lixo) management in Mozambique's capital city Maputo and its informal settlements as an entry point for assessing the relationship between these two urban development perspectives. It shows that while the Municipality considers itself to be working actively through public-private partnerships to handle the complex issue of waste management in the informal areas, people in these informal settlements, despite paying a regular fee for waste removal, continue to experience lixo as a serious problem and see its persistent presence as a symbol of spatial and social inequalities and injustice. The paper is formulated as a conversation between the city planning and management and the community side of the equation - leading to a joint set of proposals for how the management of such a contentious part of African urban life can best be dealt with

Developing a methodology for a landscape-based approach to urban conservation. The case of Maputo, Mozambique.

The broad scope of this research study is to provide a contribution and stimulate methodological as well as operational reflection and advance on the debate regarding the need to support a historic urban landscape approach to urban heritage conservation, management and planning in order to develop an urban plan able to foster the city identity and improve urban quality. In particular, this research seeks to provide deeper insights on the following specific question: “How the HUL approach can help to assess the heritage values of a city in Sub-Saharan Africa, inform decision-making and the development of a sustainable landscape-based and values-informed plan, contributing to sustain the qualitative conservation and transformation of an urban area?” The research will explore this question based on the example derived from the city of Maputo, Mozambique, with the intention to bring the theoretical discussion around this debate to a more operational perspective and level of analysis. In addition, considering the data required and given the richness and depth of the evidence required for this research, a case study has being selected and studied in detail, namely the Urban Development Plan of the Historic District (Baixa) of Maputo, which has been developed between 2013 and 2015 by the Municipality with funding from the World Bank. Based on the results of the fieldwork study and of the analysis of a real heritage conservation initiative, this research specific objective is to contribute on the design and application of the methodology needed for the HUL implementation, by developing an empirical participatory and interdisciplinary methodological process to qualify heritage cultural significance, and identify how it can be translated into policies formulation and urban conservation practices that fosters a city identity, liveability and urban quality

Honey health benefits and uses in medicine

The generation of reactive oxygen species (ROS) and other free radicals during metabolism is an essential and normal process that ideally is compensated through the antioxidant system. However, due to many environmental, lifestyle, and pathological situations, free radicals and oxidants can be produced in excess, resulting in oxidative damage of biomolecules (e.g., lipids, proteins, and DNA). This plays a major role in the development of chronic and degenerative illness such as cancer, autoimmune disorders, aging, cataract, rheumatoid arthritis, cardiovascular, and neurodegenerative diseases (Pham-Huy et al. 2008; Willcox et al. 2004). The human body has several mechanisms to counteract oxidative stress by producing antioxidants, which are either naturally synthetized in situ, or externally supplied through foods, and/or supplements (Pham-Huy et al. 2008).info:eu-repo/semantics/publishedVersio

The Role of Honey and Propolis in the Treatment of Infected Wounds

Honey is defined as the natural substance produced by Apis mellifera bees from plant nectar, from secretions of the living parts of plants, or from the excretions of plant sucking insects feeding on the living parts of plants.1,2 Honeybees collect, transform, and combine this with specific substances of their own, and then store it and leave it in the honeycomb to ripen and mature. This natural product is generally composed of a complex mixture of carbohydrates and other less common substances, such as organic acids, amino acids, proteins, minerals, vitamins, lipids, aroma compounds, flavonoids, pigments, waxes, pollen grains, several enzymes and other phytochemicals.3 5 However, the specific composition depends on many factors, such as the nectar composition of the source plant, the species of bee, the climate, environmental and seasonal conditions, agricultural practices and treatment of honey during extraction and storage.6-9 As a natural, unprocessed and easily digested food, honey plays an important role in the human diet, and is also used in pharmaceutical and cosmetic industries.10 Modern science has studied the medical significance of honeys in healing wounds and burns,11 oncology care,12 as well as its antioxidant and antimicrobial properties.info:eu-repo/semantics/publishedVersio

Augmentation of Clozapine with Aripiprazole in Severe Psychotic Bipolar and Schizoaffective Disorders: A Pilot Study

AIM: To evaluate the efficacy and safety of the augmentation of clozapine with aripiprazole in patients with treatment-resistant schizoaffective and psychotic bipolar disorders in a retrospective manner. Pharmacodynamic and pharmacokinetic interactions between the two drugs were also investigated. PATIENTS: Three men and 4 women (median age 36 and 40 years, respectively) who had mean scores at BPRS and CGI-Severity of 59.1+/-12.0 and 5.4+/-0.5, respectively, were treated with clozapine (mean dose 292.9+/-220.7 mg/day). Patients received an adjunctive treatment with aripiprazole (mean dose 6.8 +/- 3.7 mg/day). Clozapine, norclozapine and aripiprazole plasma levels were measured by means of a high performance liquid chromatograpy with UV detection. RESULTS: Total scores at BPRS decreased significantly (from 59.1+/-12.0 to 51.1+/-15.6, p=0.007) after aripirazole augmentation. In particular, the factors "thought disorder" (from 10.4+/-4.4 to 9.0+/-4.5, p=.047) and "anergia" (from 10.0+/-2.7 to 8.0+/-2.4, p=.018) significantly improved. Concomitant administration of aripiprazole and clozapine did not result in an increase in side effects over the period of treatment. Dose-normalized plasma levels of both clozapine and norclozapine and the clozapine/norclozapine metabolic ratio in all patients did not vary as well. CONCLUSION: The augmentation of clozapine with aripirazole was safe and effective in severe psychotic schizoaffective and bipolar disorders which failed to respond to atypical antipsychotics. A possible pharmacokinetic interaction between clozapine and aripiprazole does not account for the improved clinical benefit obtained after aripiprazole augmentation

Reciprocal regulation of TORC signaling and tRNA modifications by Elongator enforces nutrient-dependent cell fate

Nutrient availability has a profound impact on cell fate. Upon nitrogen starvation, wild-type fission yeast cells uncouple cell growth from cell division to generate small, round-shaped cells that are competent for sexual differentiation. The TORC1 (TOR complex 1) and TORC2 complexes exert opposite controls on cell growth and cell differentiation, but little is known about how their activity is coordinated. We show that transfer RNA (tRNA) modifications by Elongator are critical for this regulation by promoting the translation of both key components of TORC2 and repressors of TORC1. We further identified the TORC2 pathway as an activator of Elongator by down-regulating a Gsk3 (glycogen synthase kinase 3)-dependent inhibitory phosphorylation of Elongator. Therefore, a feedback control is operating between TOR complex (TORC) signaling and tRNA modification by Elongator to enforce the advancement of mitosis that precedes cell differentiation
