The effects of replacing native forest with different pasture-based animal production systems on soil microbial biomass and enzymatic activity for fruit cultivation in the Guadalupe Plateaus (PI) were evaluated. Soil samples collected during dry rainy seasons (0-10 cm). monoculture studied were: Acerola, Banana, Guava, a fragment Cerrado forest. areas solely banana guava showed higher Cmic valu...

The study aims to evaluate the effect of dragon fruit peel flour (DPF) on meat quality broiler chicken. A total 96 DOCs Ross strain were randomly divided into 4 treatments and 6 replications. included T0=Basal diet (BD), T1=BD + 0.5% DPF, T2=BD 1% T3=BD 1.5% DPF. Data analyzed using ANOVA Duncan Multiple Range Test. Observed variables water content, dry matter, protein, fat mass chicken’s meat....

Previously, we showed that oxidant exposure in renal proximal tubular cells (RPTC) induces mitochondrial dysfunction mediated by PKC-epsilon. This study examined the role of ERK1/2 in mitochondrial dysfunction induced by oxidant injury and whether PKC-epsilon mediates its effects on mitochondrial function through the Raf-MEK1/2-ERK1/2 pathway. Sublethal injury produced by tert-butylhydroperoxid...

In early spring, red wood ants Formica polyctena are often observed clustering on the nest surface in large numbers basking in the sun. It has been hypothesized that sun-basking behaviour may contribute to nest heating because of both heat carriage into the nest by sun-basking workers, and catabolic heat production from the mobilization of the workers' lipid reserves. We investigated sun-baskin...

The measurement of soil carbon dioxide respiration is a means to gauge biological soil fertility. Test methods for respiration employed in the laboratory vary somewhat, and to date the equipment and labor required have somewhat limited more widespread adoption of such methodologies. The purpose of this research is to compare the results of measured soil CO2 respiration using three methods: (1) ...

BACKGROUND Substituting galactose for glucose in cell culture media has been suggested to enhance mitochondrial metabolism in a variety of cell lines. We studied the effects of carbohydrate availability on growth, differentiation and metabolism of C2C12 myoblasts and myotubes. METHODOLOGY/PRINCIPAL FINDINGS We measured growth rates, ability to differentiate, citrate synthase and respiratory c...

BACKGROUND CryAB (HspB5) and HspB2, two small heat shock genes located adjacently in the vertebrate genome, are hypothesized to play distinct roles. Mice lacking both cryab and hspb2 (DKO) are viable and exhibit adult-onset degeneration of skeletal muscle but confounding results from independent groups were reported for cardiac responses to different stressful conditions (i.e., ischemia/reperfu...

An investigation on soil organic carbon,total N and NO3--N,available microbial biomass C,N and basal respiration and metabolic quotients(qCO2)was conducted to compare diferences in soil microbial properties and nutrients between 1 5-year-old pure Chi— nese fir(Cunninghamia lanceolata)and two mixed Chinese fir plantations(mixed plantations with A/nus cremastogyne,mixed plantations with Kalopanax...

BACKGROUND Loss of biodiversity and increased nutrient inputs are two of the most crucial anthropogenic factors driving ecosystem change. Although both received considerable attention in previous studies, information on their interactive effects on ecosystem functioning is scarce. In particular, little is known on how soil biota and their functions are affected by combined changes in plant dive...
