1. Mucociliary Clearance of Different Respiratory Conditions: A Clinical Study
Abstract Introduction Mucociliary clearance (MCC) is the first line of defense of the pulmonary system. Mucociliary clearance impairment may lead to increased risk of respiratory infections, lung injury, pulmonary repair problems, chronic dysfunctions and progression of respiratory diseases. Objective To characterize the MCC of active and passive smokers a

2. PERCEPTION, ATTENTION AND DEMONSTRATIVE THOUGHT: IN DEFENSE OF A HYBRID METASEMANTIC MECHANISM
Abstract Demonstrative thoughts are distinguished by the fact that their contents are determined relationally, via perception, rather than descriptively. Therefore, a fundamental task of a theory of demonstrative thought is to elucidate how facts about visual perception can explain how these thoughts come to have the contents that they do. The purpose of thi

3. Acrylamide reduces plasma antioxidant vitamin levels in rats due to increased oxidative damage
RESUMO Objetivo A acrilamida é um químico potencialmente neurotóxico e carcinogênico, sendo naturalmente criada durante o processo de aquecimento de alimentos ricos em carboidratos, como batatas fritas e cereais matinais. Dado que o composto pode ser ingerido através do consumo de alimentos, o presente trabalho teve por objetivo investigar o seu efeito

4. Inflammation: friend or foe of bovine reproduction?
Abstract Inflammation is not only the first line of defense of the organism but is also required in many reproductive processes such as ovulation, corpus luteum development, luteolysis, uterine clearance after insemination and post partum. Nevertheless, if excessive or persistent, inflammation can switch from a positive mechanism to a deleterious process, im

5. Particularities and Clinical Applicability of Saccharin Transit Time Test
Abstract Introduction The importance ofmucociliary clearance (MCC) for the respiratory system homeostasis is clear. Therefore, evaluating this defense mechanism is fundamental in scientific research and in the clinical practice of pulmonology and of associated areas. However, MCC evaluation has not been so usual due to the complexity ofmethods that use rad

6. NMR-Based Metabolomic Screening for Metabolites Associated with Resistance to Meloidogyne javanica in Annona muricata Roots
The resistance of Annona muricata roots to the nematode Meloidogyne javanica was investigated by nuclear magnetic resonance (NMR)-based metabolomics in combination with principal component analysis (PCA). Metabolic changes in roots exposed and not exposed to the nematode were evaluated and compared. In addition, the presence of nematicidal compounds in the r

7. Biochemical changes in cultivars of sweet oranges infected with citrus tristeza virus
Resumo As frutas cítricas ocupam um lugar de considerável importância na economia do Paquistão, assim como o resto do mundo. A doença da tristeza causada pelo Vírus da Tristeza dos Citros (CTV) existe em várias formas que podem ou não apresentar sintomas nas plantas. Os compostos bioativos e antioxidantes estão naturalmente presentes nas plantas e

8. O discurso médico sobre as emoções vivenciadas na interação com o paciente: contribuições para a prática clínica
O estudo das emoções na prática clínica expõe sua influência na relação médico-paciente. Este artigo apresenta os resultados de uma pesquisa qualitativa cujo objetivo foi explorar o discurso dos médicos sobre as próprias emoções no atendimento a pacientes. Das entrevistas com oito médicos foram extraídos os seguintes temas de análise: funçã

9. Use of domperidone in canine visceral leishmaniasis: gaps in veterinary knowledge and epidemiological implications
A pivotal strategy to decrease the risk of visceral leishmaniasis in humans is to control the infection and disease progression in dogs, the domestic reservoir of Leishmania infantum (L. chagasi). Immunotherapy is a viable approach to treat sick dogs because cell-mediated immunity is the principal defense mechanism against L. infantum. Domperidone is an immu

10. Comparative transcriptome profile of the leaf elongation zone of wild barley (Hordeum spontaneum) eibi1 mutant and its isogenic wild type
Abstract The naturally occurring wild barley mutant eibi1/hvabcg31 suffers from severe water loss due to the permeable leaf cuticle. Eibi1/HvABCG31 encodes a full ATP-binding cassette (ABC) transporter, HvABCG31, playing a role in cutin deposition in the elongation zone of growing barley leaves. The eibi1 allele has pleiotropic effects on the appearance of l

11. Physical exercise-induced fatigue: the role of serotonergic and dopaminergic systems
Brain serotonin and dopamine are neurotransmitters related to fatigue, a feeling that leads to reduced intensity or interruption of physical exercises, thereby regulating performance. The present review aims to present advances on the understanding of fatigue, which has recently been proposed as a defense mechanism instead of a “physiological failure” in

12. Gamma radiation treatment activates glucomoringin synthesis in Moringa oleifera
Abstract Plants are a very rich source of pharmacologically relevant metabolites. However, the relative concentrations of these compounds are subject to the genetic make-up, the physiological state of the plant as well as environmental effects. Recently, metabolic perturbations through the use of abiotic stressors have proven to be a valuable strategy for in
