Biomodulation of inflammatory cytokines related to oral mucositis by low-level laser therapy

This study evaluated the effects of LLLT on the expressionof inflammatory cytokines related to the development of oralmucositis by gingival fibroblasts. Primary gingival fibroblastswere seeded on 24-well plates (105cells/well) for 24 h. Freshserum-free culture medium (DMEM) was then added, andcells were placed in contact with LPS (Escherichia coli,1 lgmL1), followed by LLLT irradiation (LaserTABLE—InGaAsP diode prototype—780 nm, 25 mW) delivering 0,0.5, 1.5 or 3 J cm². Cells without contact with LPS werealso irradiated with the same energy densities. Gene expres-sion of TNF- a, IL-1b, IL-6 and IL-8 was evaluated by Real-Time PCR, and protein synthesis of these cytokines wasdetermined by enzyme-linked immunosorbent (ELISA) assay.Data were statistically analyzed by the Kruskal– Wallis test,complemented by the Mann–Whitney test (P < 0.05). LPStreatment increased the gene expression and protein synthesisof TNF-a, IL-6 and IL-8, while the expression of IL-1b wasnot affected. For LPS-treated groups, LLLT promoted signif-icant decreases in the expression of TNF-a, IL-6, and IL-8 at1.5 J cm2and 3 J cm2. These results demonstrate thatLLLT promoted a beneficial biomodulatory effect on theexpression of inflammatory cytokines related to oral mucosi-tis by human gingival fibroblasts.

Efeitos da adição de agentes tróficos na dieta de leitões desmamados sobre a expressão da enzima ornitina descarboxilase, os conteúdos de proteína e DNA e o desempenho

Two experiments were carried out to evaluate the effect of adding glutamine, fish oil or yeast cellular wall to the diet of weaned piglets on the expression of the enzyme ornithine decarboxylase (ODC), the protein content and DNA in small intestine samples and on performance. In the first experiment, 24 weaned piglets were used to measure the performance at the phases prestarter, starter 1 and starter 2. Four diets were tested (T1 -basal diet (BD); T2 -BD + 1% of glutamine; T3 -BD + 0,2% of yeast cellular wall; T4 -BD + 5% of fish oil). At the second experiment 45 weaned piglets were used and distributed in a randomized block design, in factorial outline with four diets and three slaughter ages (on the day of weaning, on the seventh and fourteenth days postweaning). The tested diets did not alter the piglets' performance in none of the phases. There was reduction of the expression of the ODC enzyme, of the protein concentration and of the relationship protein/DNA to the seven days postweaning, with increase of the values on the 14th day, evidencing a state of hypotrophy of the mucous membrane, suggesting that the process of protein synthesis in the small intestine was diminished in the first week after weaning, but it presented recovery signs in the second week.

Recovery of anchovy (Engraulis anchoita) and whitemouth croaker (Micropogonias furnieri) proteins by alkaline solubilisation process

The aim of this study was to evaluate the physical, chemical, and functional properties of recovered proteins of anchovy (Engraulis anchoita) and whitemouth croaker (Micropogonias furnieri) through the process of alkaline solubilisation and isoelectric precipitation, using different solubilisation (NaOH and KOH) and precipitation (HCl and H3PO4) reagents. The tests showed high protein level, and the lowest lipid reduction (94.5%) was found in the recovered protein of anchovy, the lowest yield of the process was 76.1%. The highest whiteness (78.8 and 74.2) was found in whitemouth croaker proteins. The solubilisation of the recovered protein was studied in the pH range (3, 5, 7, 9, and 11). The maximum solubility was at pHs 3 and 11 and minimum solubility was at pH 5 in the species under study.

Effect of organic sources of minerals on fat-corrected milk yield of dairy cows in confinement

This study evaluated the effects of organic and inorganic sources of minerals in diets for mid-lactation dairy cows on milk yield and composition, intake and total apparent digestibility of dry matter and nutrients, blood parameters, microbial protein synthesis, and energy and protein balances. Twenty Holstein cows averaging 146.83 +/- 67.34 days in milk and weighing 625.30 +/- 80.37 kg were used. The experimental design was a crossover. Diets were composed of corn silage (50%), ground grain corn, and soybean meal, differing with regard to the sources of trace minerals, plus an organic and inorganic mix. The organic mineral source increased milk fat and fat-corrected milk yield without changing milk yield, intake, or total apparent digestibility. Blood parameters, microbial protein synthesis, and energy and protein balances were not affected by the sources of minerals. Organic sources of minerals improve milk fat yield without affecting other parameters.
