1. Protective effects of salidroside on chronic heart failure in rats and the underlying mechanisms
The present study aimed to investigate the protective effects of salidroside on chronic heart failure (CHF) in rats and to explore the underlying mechanisms. One hundred SD rats were randomly divided into sham-operated, model, and low-, medium- and high-dose salidroside groups. The CHF model was established in later 4 groups. The later 3 groups were intragas

2. The Differential Expression and Snp Analysis of the Ovoinhibitor Gene in the Ovaries of Laying Duck Breeds (Anas Platyrhynchos)
ABSTRACT Ovoinhibitor (OIH) is the main proteinase inhibitor in the egg white. In the present study, real-time quantitative PCR and Western-Blot were used to analyze different expression pattern of OIH in ovaries as a candidate gene of reproductive traits in Jingjiang ducks (JJ ducks) and Shaoxing ducks (SX ducks) during three laying stages. To study the pol

3. Trypsin inhibitor from tamarindus indica L. seeds reduces weight gain and food consumption and increases plasmatic cholecystokinin levels
OBJECTIVES: Seeds are excellent sources of proteinase inhibitors, some of which may have satietogenic and slimming actions. We evaluated the effect of a trypsin inhibitor from Tamarindus indica L. seeds on weight gain, food consumption and cholecystokinin levels in Wistar rats. METHODS: A trypsin inhibitor from Tamarindus was isolated using ammonium sulfate

4. Kazal-type serine proteinase inhibitors in the midgut of Phlebotomus papatasi
Sandflies (Diptera: Psychodidae) are important disease vectors of parasites of the genus Leishmania, as well as bacteria and viruses. Following studies of the midgut transcriptome of Phlebotomus papatasi, the principal vector of Leishmania major, two non-classical Kazal-type serine proteinase inhibitors were identified (PpKzl1 and PpKzl2). Analyses of expres

5. Transcriptome analysis of resistant soybean roots infected by Meloidogyne javanica
Soybean is an important crop for Brazilian agribusiness. However, many factors can limit its production, especially root-knot nematode infection. Studies on the mechanisms employed by the resistant soybean genotypes to prevent infection by these nematodes are of great interest for breeders. For these reasons, the aim of this work is to characterize the trans

6. Bioatividade de berenil, um inibidor de proteases do tipo bis-benzamidina, sobre Thyrinteina arnobia / Bioactivity of berenil, a proteinase inhibitor bis-benzamidine, on Thyrinteina arnobia
Os inibidores de protease (IPs) têm sido reconhecidos como agentes potenciais de proteção a plantas na defesa contra insetos-praga, sendo sua utilização estudada como alternativa para o manejo integrado de pragas. Berenil é um exemplo de um inibidor sintético de tripsinas do tipo bis-benzamidina e seu potencial para uso como inseticida foi estudado co

7. Influência da qualidade de diferentes tipos de arroz e inibidores de proteinases no rendimento e na virulência de conídios do fungo entomopatogênico Metarhizium anisopliae (Mestch.) Sorokin (Ascomycota: Hypocreales) / Influence of quality of different types of rice and proteinase inhibitors on yield and virulence of conidia of the entomopathogenic fungus Metarhizium anisopliae (Mestch.) Sorokin (Ascomycota: Hypocreales)
In order to optimize the production process of Metarhizium anisopliae, the present study aimed to determine the effects of soybean proteinase inhibitors on growth, sporulation and virulence of the fungus and to compare yield, viability and virulence of M. anisopliae conidia produced in different types of rice and additives. The addition of 5 g.L-1 of semi-pu

8. Participação do L-NAME, da L-arginina e da N-acetilcisteína no enfisema pulmonar induzido por fumaça de cigarro em camundongos / The lung remodeling in mouse emphysema is independent of nitric oxide modulation
Nitric oxide (NO) represents one of the most important intra and extracellular mediators/messengers. It takes part in both biologic and pathologic processes. This study aimed to verify NO role in pulmonary emphysema induced by cigarette smoke (CS) in mice. So L-NAME (LN) (a NOinhibitor) and L-arginine (LA) (a substract for NO formatio

9. Polymorphism of alpha-1-antitrypsin in hematological malignancies
Alpha-1-antitrypsin (AAT) or serine protease inhibitor A1 (SERPINA1) is an important serine protease inhibitor in humans. The main physiological role of AAT is to inhibit neutrophil elastase (NE) released from triggered neutrophils, with an additional lesser role in the defense against damage inflicted by other serine proteases, such as cathepsin G and prote

10. Extration and chromatographic analyses of a present inhibitor of tripsina in leaves of mamona and its action in the development of the lagarta-do-cartucho of the maize. / ExtraÃÃo e anÃlises cromatogrÃficas de um inibidor de tripsina presente em folhas de mamona e sua aÃÃo no desenvolvimento da lagarta-do-cartucho do milho.
Ao longo de sua evoluÃÃo, as plantas tÃm se defendido do ataque de insetos e de outros organismos, atravÃs de inÃmeros mecanismos, entre os quais destacam-se a sÃntese e o acÃmulo de proteÃnas de defesa, tais como os inibidores de proteinase. Desde a descoberta dos inibidores de proteinases como agentes de defesa vegetal, vÃrias tentativas tÃm sido

11. Enzimas de organismos aquÃticos e suas aplicaÃÃes fisiolÃgicas
In the last years, there has been a general increase in human demand for fishery products, followed by a significant increase in the world production of aquatic organisms. The growth of fishery industry generates, as consequence, large amounts of wastes and by-products rich in biomolecules, which are discharged into envioronment. Fishery wastes can be used i

12. Purification and characterization of the aprotinin from porcine lung. / Purificação e caracterização da aprotinina obtida de pulmão suíno.
Aprotinin, an acid stable serine proteinase inhibitor with a molecular mass of 7 kDa, is used as a reagent or drug. The purification of the aprotinin from porcine lungs was the main objective of this work. Three procedures were used. The first one utilized the trypsin-agarose column. The tangential ultra filtration and trypsin-Sepharose column were used in t
