Efficacy of Duddingtonia flagrans and Arthrobotrys robusta in controlling sheep parasitic gastroenteritis

Abstract: The aim of this study was to evaluate the efficacy of formulations of sodium alginate matrix (pellets) of the nematode predatory fungi, Duddingtonia flagrans (AC001 isolate) and Arthrobotrys robusta (I-31 isolate), in the biological control of sheep gastrointestinal nematode infections. Thirty young Bergamacia ewes were allocated into three groups: In group 1 (control), the animals received 2 g/10 kg of live weight (l.w.) of pellets without fungus; in group 2, each animal received 2 g/10 kg of l.w. of pellets of D. flagrans (0.2 g of fungus/10 kg l.w.); and in group 3, each animal received 2 g/10 kg of l.w. of pellets of A. robusta (0.2 g of fungus/10 kg l.w.). The animals of each group were kept separately under rotational grazing. Pellets, with or without fungi, were mixed with 1 kg animal food and administered twice a week for 6 months. There was no significant difference in mean live weight and packed cell volume among groups (P > 0.05). Mean nematode fecal egg counts (FEC) did not significantly differ between the control and the remaining groups, except in one or two collections, when FEC was higher in the control group than in group 2 and group 3, respectively. The group that received A. robusta pellets needed less salvage anthelmintic treatments. Haemonchus contortus was the predominant species recovered from tracer lambs. The nematophagous fungi, D. flagrans and A. robusta, did not provide satisfactory results in the prophylaxis of parasitic gastroenteritis in sheep, under the conditions of the present study.

Relationship between Proinflammatory Cytokines/Chemokines and Adipokines in Serum of Young Adults with Obesity.

Abstract: Background and objective The adipose tissue has been recognized as an important endocrine organ, which is metabolically active and expresses and secretes various inflammatory cytokines. Inflammation is involved in obesity-related complications. As such, the present study investigated the correlation between biochemical parameters, serum proinflammatory cytokines and adipokines in individuals with obesity. Methods Based on the body mass index (BMI), 30 subjects were divided into 3 groups: eutrophic (GC, n = 10), overweight (GOW, n = 10) and obese (GOB, n = 10). Serum glucose, cholesterol (total-C, HDLC and LDL-C), triglycerides, total proteins, uric acid and insulin were determined, as well as cytokines IL-8, TNF-α, IL-1β, and IL-6, leptin and adiponectin. Results GOB showed the highest glucose, total and LDL-C, triglycerides, uric acid, insulin, leptin, IL- 8, IL-1β, IL-6, TNF-α and lowest adiponectin levels. In general, adiponectin exhibited an inverse correlation with BMI, abdominal circumference, LDL-C, IL-6, TNF-α, leptin and leptin-adiponectin ratio (LAR) and a positive correlation with HDL-C. Leptin was positively correlated with BMI, abdominal circumference, insulin, IL-6, TNF-α and LAR and negatively correlated with HDL-C and adiponectin. The LAR was positively correlated with BMI, waist circumference, insulin, TNF-α and negatively associated with HDL-C. Conclusion The results confirm that obesity changes the lipid and glycemic profiles of individuals, increases the proinflammatory adipokine levels and reduces those of anti-inflammatory adipokines, promoting a state of chronic inflammation.

Active aging: prevalence and gender and age differences in a population-based study.

Abstract: O objetivo deste estudo foi analisar as prevalencias e as diferencas de genero e idade em indicadores de envelhecimento ativo entre idosos participantes do Inquerito de Saude do Municipio de Campinas, Sao Paulo, Brasil, 2014-2015. Estimaram-se as prevalencias de participacao dos idosos em doze atividades relativas a quatro dimensoes, e as razoes de prevalencia foram calculadas pela regressao de Poisson. A populacao de estudo foi composta por 986 idosos. Os resultados revelaram que 40,2% dos idosos participavam de atividades socioculturais, 25,3% eram fisicamente ativos no lazer, 21,7% usavam a Internet, 22,1% exerciam trabalho remunerado e apenas 2,6% realizavam cursos. Quanto a dimensao social, so houve diferenca entre os sexos na frequencia aos cultos religiosos, sendo menos prevalente entre os homens (RP = 0,67). Na dimensao da atividade fisica, os homens eram mais ativos no trabalho (RP = 2,10), no deslocamento (RP = 1,61) e no lazer (RP = 1,44). Na dimensao intelectual, nao houve diferenca entre os sexos e, em relacao ao trabalho remunerado, os homens eram mais ativos (RP = 1,78). As analises segundo faixas etarias evidenciaram que, entre os homens, apenas a pratica de atividade fisica no trabalho e o exercicio de trabalho remunerado apresentaram menor prevalencia no grupo de 80 anos e mais. Entre as mulheres mais longevas, foram identificadas menores prevalencias em seis atividades, o que sinaliza possivel efeito diverso do avanco da idade entre os sexos. Os resultados revelam expressiva participacao dos idosos em alguns dos indicadores do envelhecimento ativo e os desafios no que concerne as atividades pouco realizadas e as diferencas de participacao entre os sexos.
