Studies on the Antioxidant Potential of Extracts from Unripe Fruit of Carica papaya

引用

Journal of Life Sciences 2012年第1期6卷 41-47页

作者： Omotade Oloyede Daniel Roos joao rocha Biochemistry Department University of Ado-Ekiti Ekiti State 5363 Nigeria Departmento de Quimica Bioquimica Toxicologia （CCNE） Universidade Federal de Santa Maria Santa Maria 97105-900 Brazil

The antioxidant activities of the ethyl acetate fraction and aqueous extract of unripe fruit of Carica papaya were compared and investigated in vitro using thiobarbituric reactive species （TBARS） assay, total phenol content, evaluation of reactive oxygen species （ROS） in liver mitochondria, Fe2＋ chelating and 2,2-diphenyl-lpicrylhydrazyl （DPPH） scavenging activities. Both extracts had high antioxidant properties and could inhibit FeE＋ and sodium nitroprusside lipid peroxidation in the liver. Total phenol content of ethyl acetate fraction and aqueous extract were 4.50 ±2.26 and 1.21±3.12 mg/g, respectively. Both extracts had a maximal effect at the lowest concentrations tested （15 μg/mL for ethyl acetate and 150 μg/mL for the aqueous）. Ethyl acetate fraction showed that the highest values of antioxidant activity is probably associated with its high phenolic content, Fe2＋ chelating and DPPH scavenging activities. It is therefore concluded that ethyl acetate fraction and to a less extent the aqueous fractions are potent inhibitor of lipid peroxidation.

Green Tea(Camellia sinensis):Hypocholesterolemic Effects in Humans and Anti-Inflammatory Effects in Animals

引用

Food and Nutrition Sciences 2014年第22期5卷 2185-2194页

作者： Márcia Reto Cristina Almeida joao rocha Bruno Sepodes Maria-Eduardo Figueira Research Institute for Medicines(iMed.ULisboa) Faculty of PharmacyUniversity of LisbonLisbonPortugal

In its essence, tea is an infusion of Camellia sinensis leaves and it is the most widely consumed beverage in the world, aside water. Animal and epidemiological studies have associated green tea consumption with several health benefits, which include hypocholesterolemic effect and anti-in-flammatory activity. In this study catechins levels of green tea and its effect on the lipid profile of humans were evaluated as well as the protective effects against H2O2-mediated damage in human fibroblasts and anti-inflammatory activity of (–)-epigallocatechingallate (EGCG). The daily consumption of 1200 mL of green tea for 30 days by 15 human volunteers promoted the decrease of cholesterol and LDL levels after 15 days, but this effect was not persistent after 30 days. No changes were observed in lipid profile after the consumption of green tea capsules. EGCG, a major green tea catechin, demonstrated an anti-inflammatory action in rats and an antioxidant effect in cultured human fibroblasts.

The cultivation of the marine species of shrimp Litopenaeus vannamei has emerged as one of the segments that best develop in the Brazilian aquaculture, representing the agribusiness that grew the most in recent years. Regarding the economic importance of the farming of this species in Brazil, further studies on genetic improvement were conducted. A F2 segregating population consisting of 192 samples for each G1 and G2 families, from crossing inbred lines was used for the studies performed in the present work. The genetic linkage analysis was based on polymorphic markers derived from nine AFLP (Amplified Fragment Length Polymorphism) primers. Fourteen genetic linkage groups including 103 segregating polymorphic markers were constructed covering350 cMfor G1 and four genetic linkage groups including 59 markers were constructed covering300 cMfor G2. Simple marker analyses were performed among individuals evaluated phenotypically, finding markers linked to genes that may be potentially important and useful to assess characteristics of economic importance for traits related to weight and the disease IMN (idiopathic muscle necrosis). The statistical model including markers explained major proportion of phenotypic characteristic weight in relation to disease incidence IMN.

Fine Needle Aspiration Cytology in the Diagnosis of Canine Cutaneous Transmissible Venereal Tumor—Case Report

引用

Open Journal of Veterinary Medicine 2014年第9期4卷 204-209页

作者： Noeme Sousa rocha Talia Missen Tremori joao Alexandre Matos Carneiro Departament of Veterinary Clinic Faculty of Veterinary Medicine and Animal Science-UNESPBotucatuBrazil Department of Animal Reproduction and Veterinary Radiology Faculty of Veterinary Medicine and Animal Science-UNESPBotucatuBrazil

Fine needle aspiration cytology (FNAC) has been widely used in the diagnosis of lesions from various origins, especially neoplastic. The technique is simple, fast, safe, minimally invasive and inexpensive, which allows through the evaluation of cell morphology to establish prognosis, delineate surgical margins, monitor lesion growth, validate indication euthanasia during surgery and monitor chemotherapy protocols. Diagnosis of canine transmissible venereal tumor (TVT) can be accomplished with ease and precision, even to be rated, according to the degree of aggressiveness. The study objective was to demonstrate the effectiveness of the examination in the diagnosis of TVT plasmacytoid type. An eight-month dog presented to the veterinary hospital (HV), faculty of veterinary medicine and animal science, FMVZ, UNESP-Univ Estadual Paulista with clinical suspicion of cutaneous lymphoma. By presenting multiple nodular lesions, FNAC was performed to cytological diagnosis. The tissue showed cells consistent with TVT. The animal was treated, and a total cure was achieved. According to the literature, TVT mainly affects external genitalia of sexually active animals and its transmission is more frequent during intercourse. In addition, animals sexually immature and without contact to the street dogs, hardly have injuries by TVT. In this case, verrucous and ulcerated lesions on the vulva of its mother during pregnancy and childbirth infected the animal. Diffuse and predominant dorsal injuries occurred due to both exfoliation of breast tumor during delivery and immunosuppression of pup at birth, thus favoring an atypical transmission.
