1. Physiology of the forage cactus cultivate Opuntia stricta (Haw.) Haw under different irrigation frequencies in the Semiarid
ABSTRACT The objective of this work was to evaluate the physiological variables of the cultivar Opuntia stricta (Haw.) Haw in the first cycle and in the regrowth, under different frequencies of drip irrigation, cultivated in the Agreste da Paraíba mesoregion. Therefore, a randomized block design was used, with 2 treatments (irrigation frequencies) and 4 rep

2. Therapeutic failure with itraconazole in sporotrichosis due to bariatric surgery,
Abstract Sporotrichosis is a deep mycosis of subacute or chronic evolution, caused by the dimorphic fungus of the genus Sporothrix. The treatment is carried out with antifungal orally or intravenously. Therapeutic success can be affected by several factors, such as altered gastrointestinal physiology by surgery. More and more patients are submitted to bariat

3. Effect of mouse antisera targeting the Phlebotomus papatasi midgut chitinase PpChit1 on sandfly physiology and fitness
In sandflies, the absence of the peritrophic matrix (PM) affects the rate of blood digestion. Also, the kinetics of PM secretion varies according to species. We previously characterised PpChit1, a midgut-specific chitinase secreted in Phlebotomus papatasi (PPIS) that is involved in the maturation of the PM and showed that antibodies against PpChit1 reduce th

4. Modeling temporal variations of Gracilaria Greville and Hypnea J.V. Lamouroux (Rhodophyta) assemblages on a midlittoral reef platform at Piedade Beach, Pernambuco State, Brazil
The diversity of algal banks composed of species out the genera Gracilaria Greville and Hypnea J.V. Lamouroux have been impacted by commercial exploitation and coastal eutrophication. The present study sought to construct dynamic models based on algal physiology to simulate seasonal variations in the biomasses of Gracilaria and Hypnea an intertidal reef at P

5. Avaliação do condicionamento fisiológico e aplicação de fósforo em sementes de milheto / Physiological conditioning and phosphorous application on pearl millet seeds
Beside the many aptitudes of the pearl millet (stock feeding, hay, soil layer protection and food in general), some factors limit its expansion in Brazil, being generally, the low physical and physiological seed quality on the market as one of the harshest problems. Thus, this study aimed at applying physiologic conditioning techniques, pelleting and phospho

6. Fotossíntese, crescimento e composição química em plantas de Theobroma cacao L. submetidas a diferentes concentrações de silicato de potássio e sua interação com insetos-praga / Photosynthesis, growth and chemical composition in plants of Theobroma cacao L. subjected to different concentrations of potassium silicate and its interaction with insect-pests
The control of insect pests through the use of pesticides, is still the most method used in the cultivation of cocoa. However, due to environmental issues, there need to seek new alternatives of control less harmful the environment and to humans. In this context, silicon is a nutrient that is being used in various cultures, due to its beneficial effects on p

7. Influence of chromium in Laguncularia racemosa (L). Gaertn f. physiology
Most studies of chromium have been realized in the sediments and in mangrove trees. However, little is known about its effect on growth and metabolism in this vegetation. L. racemosa plants were grown in solution with 20% of ionic strength of Hoagland and Arnon containing 100 mM NaCl and supplemented with 0.00, 0.05 and 0.50 mg L-1 of Cr+3. The growth, the p

8. Evaluation of acute exposure to aluminum and pH variations in the expression of gonadotropins in Oreochromis niloticus (Teleostei: Cichlidae) / Avaliação da exposição aguda ao alumínio e variações do pH na expressão de gonadotropinas em Oreochromis niloticus (Teleostei: Cichlidae)
Aluminum and acidic pH are known to be toxic to the ichthyofauna. The main goal of the present study was to evaluate the effects of aluminum and acidic pH in the reproductive physiology of Oreochromis niloticus. To conduct this experiment, females were exposed to aluminum at 0.5 mg of Al L-1 in neutral pH (Al N), 0.5 mg of Al L-1 in acidic pH (Al - Ac), a co

9. Indução da maturação de dois genótipos de cana-de-açúcar em função da interação entre doses de etefon e pH da calda de aplicação / Ripening induction of two sugarcane genotypes function of the interaction of etefon rates and spray solution pH
The ripening induction through chemical products is an usual practice in the sugarcane cropping systems in Brazil, being ethephon one of the ripeners extensively used. However, the interaction of factors related to climate and crop physiology in the application timing, with the physical-chemical properties of the ethephon may influence its efficacy. Being th

10. Intestinal molecular physiology of Dysdercus peruvianus (Hemiptera) / Fisiologia molecular intestinal de Dysdercus Peruvianus (Hemiptera)
After identification of cathepsins L in vitro assays and in zimograms we began to purify this enzyme in insect midgut. The region V2 was selected as a source of material for purifying a cysteine proteinase because it contains most of the activity of that proteinase. After several attempts to purify this proteinase, an effective process was developed that avo

11. Mecanismo de defesa e recuperação da fotossintese em Centrolobium tomentosum sob condições de estresse induzido por SO2 / Mechanism of defense and recovery of photosynthesis in Centrolobium tomentosum under conditions of stress induced by SO2
Large quantities of gaseous pollutants emited by urban-industrial areas emit contribute to the degradation of ecosystems with subsequent declines in vegetation. The photosynthesis is one of the first processes altered by the action of these pollutants and sulphur dioxide (SO2), as one of the most common and harmful air pollutants, drastically affect the phot

12. Stressful factors in seed germination and in vitro propagation of Passiflora edulis Sims f. flavicarpa Degener / Fatores de estresse na germinação de sementes e na propagação in vitro de Passiflora edulis Sims f. flavicarpa Degener
The oxidative stress results into reaction series of the reactive oxygen species (ROS) that are considered as detrimental to biological membranes. In addition, the tissues can produce and liberate gases such as the ethylene and CO2, as being the first one responsible for the chlorosis, senescence and leaf abscission. High irradiance on the photosynthesizing
