1. Identification of the difference in the pathogenesis in heart failure arising from different etiologies using a microarray dataset
OBJECTIVES: Clinically, patients with chronic heart failure arising from different etiologies receive the same treatment. However, the prognoses of these patients differ. The purpose of this study was to elucidate whether the pathogenesis of heart failure arising from different etiologies differs. METHODS: Heart failure-related dataset GSE1145 was obtained

2. Regulation of Na+ and K+ homeostasis in plants: towards improved salt stress tolerance in crop plants
Abstract Soil salinity is a major abiotic stress that results in considerable crop yield losses worldwide. However, some plant genotypes show a high tolerance to soil salinity, as they manage to maintain a high K+/Na+ ratio in the cytosol, in contrast to salt stress susceptible genotypes. Although, different plant genotypes show different salt tolerance mech

3. Mecanismos de proteção da distrofia muscular : estudo proteômico e terapia farmacológica / Protective mechanisms of muscular dystrophy : proteomic study and pharmacological therapy
In Duchenne Muscular Dystrophy (DMD) and in the mdx mice model of DMD, the lack of dystrophin leads to muscle degeneration. The pathogenesis of DMD is related to sarcolemmal fragility, mechanical stress and increased influx of calcium in muscle fibers, due to dysfunction of ion channels, such as the stretch-activated calcium channels. The knowledge of the pr

4. Efeitos da privação de sono na homeostase e metabolismo do cálcio em esplenócitos de camundongos / Effects of the sleep deprivation in calcium metabolism and homeostasis on splenocytes from mice
O sono é um importante evento fisiológico que diretamente influencia a saúde e está relacionado com o sistema imunológico no qual o cálcio age como um importante mensageiro. Neste estudo, nós realizamos as medidas de mobilização do cálcio citossólico em células vivas com o objetivo de compreender as mudanças na sinalização deste íon em célul

5. InteraÃÃo entre Na+ e K+ em plantas jovens de pinhÃo manso em condiÃÃes de salinidade / Interaction between Na + and K + in young plants of jatropha under salinity
A salinidade à um fator que limita o crescimento e a rodutividade das culturas e pode estar associada à escassez de K+ , alÃm de propiciar estresses interativos sobre a nutriÃÃo das plantas. No entanto, a absorÃÃo quanto o transporte na lanta compreende uma seqÃÃncia de processos, que se dÃo desde o influxo de K+ e/ou Na+; seu carregamento no xilem

6. Interaction between human cytomegalovirus UL136 protein and ATP1B1 protein
Interplay between the host and human cytomegalovirus (HCMV) has a pivotal role in the outcome of infection. A region (referred to as UL/b’) present in the Toledo strain of HCMV and low passage clinical isolates contains 19 additional genes, which are absent in the highly passaged laboratory strain AD169. Products of the UL/b’ genes may determine the mani

7. Biochemical and hematological parameters of Nile tilapia (Oreochromis niloticus L.)under stress by exposure to air / Parâmetros hematológicos e bioquímicos da tilápia-do-nilo (Oreochromis niloticus L.) sob estresse por exposição ao ar
The present study evaluated the hematological and biochemical parameters of adult tilapia (Oreochromis niloticus) under the influence of the physiological stress factor in animals submitted to air exposure during fattening in raceway system. Blood cell count, hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpu

8. Changes in growth variables and potassium content in leaves of Black Barley in response to NaCl
Much attention is being focused on the Black barley (Hordeum distichum L.) as a local cultivar offering good model for a cereal crop has traits of resistance to drought and salinity during vegetative growth stages. Although Black was sensitive to salt stress during germination, it developed gradual tolerance with age and proved very tolerant during growth an

9. Effects of acid-base imbalance on vascular reactivity
Acid-base homeostasis maintains systemic arterial pH within a narrow range. Whereas the normal range of pH for clinical laboratories is 7.35-7.45, in vivo pH is maintained within a much narrower range. In clinical and experimental settings, blood pH can vary in response to respiratory or renal impairment. This altered pH promotes changes in vascular smooth m

10. Increased expression and purification of soluble iron-regulatory protein 1 from Escherichia coli co-expressing chaperonins GroES and GroEL
Iron is an essential metal for all living organisms. However, iron homeostasis needs to be tightly controlled since iron can mediate the production of reactive oxygen species, which can damage cell components and compromise the integrity and/or cause DNA mutations, ultimately leading to cancer. In eukaryotes, iron-regulatory protein 1 (IRP1) plays a central

11. Mechanisms of protection against myonecrosis in extraocular muscles of the mdx mice / Mecanismos de proteção a mionecrose nos musculos extra-oculares de camundongos distroficos mdx
Duchenne muscular dystrophy is one of the most common hereditary diseases. Abnormal calcium ion handling renders dystrophic muscle fibers more susceptible to necrosis. In the mdx mice, extraocular muscles (EOM) are protected and do not undergo myonecrosis. We investigated whether this protection is related to an increased expression of calcium-binding protei

12. Estudo do papel da homeostase do cálcio na reparação de danos no DNA em diferentes linhagens de Saccharomyces cerevisiae
O Ca+2 tem sido relatado como um íon de extrema importância celular. Sua concentração intracelular alterada está relacionada com: (i) a ativação de proteínas importantes, dentre elas as de reparação e de apoptose, (ii) as doenças humanas de grande relevância sócio-econômica e (iii) o aumento dos danos celulares. Sabendo-se que a sua concentraç
