There is growing evidence that kefir can be a promising tool in decreasing the risk of many diseases, including metabolic syndrome (MetS). The aim present study was to evaluate effect supplementation diet Spontaneously Hypertensive Rats (SHR) which MetS induced with monosodium glutamate (MSG), and determine its on parameters, inflammatory oxidation marker expression glycemic index control. Thirty animals were used this experiment. For induction MetS, twenty two-day-old male SHR received five...

Abstract Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) is an obligate zoophytophagous predator because its population can be maintained in the laboratory when fed on both prey and plants. We evaluated ultrastructural changes midgut digestive cells of adult B. tabidus, subjected to different treatments (starvation or feeding plant material prey) for periods. Their midguts were dissected, divided into anterior, medium posterior sections, processed, analyzed with light transmission...

Summary This study investigated the effect of bark extract Bathysa cuspidata on paraquat (PQ)‐induced extra‐pulmonary acute lung injury (ALI) and mortality in rats. ALI was induced with a single dose PQ (30 mg/kg, i.p.), animals were treated B. (200 400 mg/kg). Analyses conducted survival, cell migration, oedema, malondialdehyde, proteins carbonyls, catalase, superoxide dismutase, histopathology stereology tissue. Rats exposed to 200 mg presented lower (20% 30%), compared alone group (50%)....

This study was developed aiming to evaluate the effects of maternal feed-restriction on development gastrointestinal tract (GIT) bovine fetus at different gestational stages. Feed-restricted cows were fed 1.2 times maintenance level while control group ad libitum. Pregnant slaughtered 136, 189, 239, and 269 days gestation tracts fetuses evaluated. No nutrition body weight (P=0.17) length (P=0.13) observed. major feed restriction GIT mass observed (P=0.51). However, small intestine per unit...

The protozoan Trypanosoma cruzi triggers an inflammatory process in mammalian heart causing events such as fibrosis, changes the architecture and functionality this organ. Enalapril, angiotensin II-converting enzyme inhibitor, is a drug prescribed to ameliorate dysfunction, appears exert potential role immune system regulation. Our aim was evaluate chronic cardiac parameters after therapeutic treatment with enalapril benznidazole C57BL/6 mice infected VL-10 strain of T. . After infection,...

This work studied the ultrastructure of midgut cells Cimex hemipterus Fabricius (Hemiptera: Cimicidae). The adult insects was analyzed on different days after a bloodmeal, and three anatomical regions with digestive functions were apparent. In anterior midgut, had many spherocrystals, lipid inclusions, glycogen deposits, suggesting role in water absorption, ion regulation, digestion, storage lipids sugars. middle contained secretory granules apical cytoplasm, lysosomes, large amounts rough...

The objective of this work was to study the morphologic development and swimming feeding behaviors piracanjuba larvae, Brycon orbignyanus Valenciennes (1849) (Characiformes, Characidae, Bryconinae), during period from zero 172 hours after hatching (standard length = 3.62 - 11.94 mm). morphological analyses were accomplished by using a trinocular stereo microscope, while behavioral performed through periodic observations. In 28 hatching, larvae 6.25 ± 0.13 mm) showed following structural...

This study determined the effects of gallium-aluminum-arsenide laser (GaAlAs), gallium-arsenide (GaAs) and Dersani healing ointment on skin wounds in Wistar rats. The parameters analyzed were: type I III collagen fiber concentrations as well rate wound closure. Five wounds, 12 mm diameter, were made animals' backs. depth surgical incision was controlled by removing epithelial tissue until dorsal muscular fascia exposed. animals anesthetized with ketamine xylazine via intraperitoneal...

Evaluate the effect of flaxseed, olive and fish oil on lipid profile, preservation villosities lymphocyte migration in intestinal mucosa Wistar rats.Thirty male rats were divided into four groups, which received AIN-93M diet, with changes only to their source: olive, fish, soy (control group). The serum was separated for biochemical parameter analysis. A histological evaluation performed ileal portion.The group fed presented lower values when compared other treatments Total Cholesterol,...

Summary The aim of this study was to investigate the effects Trypanosoma cruzi ( T. ) infection on myocardial morphology, single cardiomyocyte contractile function and exercise tolerance in rats. Adult Wistar rats were randomized into control n = 14) infected groups. Infected animals inoculated with Y strain (300,000 trypomastigotes/50 g body weight). After 9 weeks, subjected a treadmill running protocol. Then, right atrium (RA) left ventricle (LV) removed for morphological cell evaluation....

In this study we describe the ultrastructure of endocrine cells observed in midgut M. quadrifasciata anthidioides. This bee has two types cells, which are numerous on posterior region. Cells closed type smaller and have irregular secretory granules with lower electrondensity than those open cell type. The elongated mitochondria mainly basal area, where most also found. Besides secretion mitochondria, species well-developed autophagic vacuoles Golgi complex elements.

The organophosphorous (OP) pesticide fenthion is widely used in commercial fruit industry and orchards South America. Among the metabolic effects mammals caused by fenthion, hyperglycemia occurs via activation of hepatic pathways, which may interfere with function several organs systems. purpose this study was to evaluate acute sub-chronic levels on energy metabolism liver morphology frugivorous bats (Artibeus lituratus), usually feed fruits cultivated American plantations where used....

The aim of this study was to evaluate the acute toxicity atrazine and pícloram separately grass carp (Ctenopharyngodon idella). Firstly, fingerlings were exposed nominal concentrations these herbicides determine lethal concentration (LC50) (96 h). After this, animals treated with sub-acute measure effects on gill histology. LC50 h) picloram were, respectively, 37 mg L−1 4.4 L−1. Four types alterations found in gills atrazine, which epithelial lifting, partial cell proliferation, lamellar...

Protein restriction (PR) is associated with cardiovascular diseases. The purpose of this study was to investigate the effects on single ventricular cardiomyocyte contractile function a short-term PR after weaning. Male Fischer rats that were 28 days old randomly divided into control group (CG, n = 16) and protein-restricted (PRG, 16). After weaning, CG PRG animals received isocaloric diets containing 15 6% protein, respectively, for 35 days. Biometric parameters then measured, hearts removed...

Hemidactylus mabouia is an Africa oviparous lizard that now distributed on other continents and has been introduced to Brazil. In the majority of reptiles, females have ability store spermatozoa in specialized regions genital tract. Considering H. storage restricted region uterine tube, this study we utilized optical transmission electron microscopy investigate processes related large number vagina. Although it was possible visualize vagina, ultrastructural analysis revealed significant...

Lizards of the family Gekkonidae display a variety reproductive patterns, as evidenced by presence viviparous and oviparous species. The species Hemidactylus mabouia is oviparous. We examined, in vitellogenic females, oviductal structure light microscopy after routine histological histochemical techniques, well scanning transmission electron microscopy. oviduct composed four different regions: infundibulum, which opens into coelomic cavity receives oocyte released at time ovulation; uterine...
