High-protein diets (HPDs) are widely used for health and performance. However, the combination of whey protein and natural foods (i.e., fruits) is still unclear. Thus, we evaluated the role of supplemental HPD with Bocaiuva (Acrocomia sp.) in metabolic and body composition parameters of rats submitted to resistance training (RT). Wistar rats (203.3 ± 30 g) were randomly allocated to five groups: normoproteic control (CON, n = 5), sedentary high-protein (SH, n = 5), RT + H (trained high-protein [TH], n = 5), sedentary+Bocaiuva (SH+B, n = 4), and RT+Bocaiuva (TH+B, n = 4) diet groups. After 12 weeks of RT, the maximal strength increased in both trained groups (P < .05). The TH + B group had lower values of adiposity index (AI) (3.8 ± 0.7% vs. 6.8 ± 1.3%) and visceral fat (0.038 ± 0.004 g/g vs. 0.067 ± 0.012 g/g) compared with the SH group, respectively (P < .05). The other groups did not show differences in values of AI (CON, 5.4 ± 1.6%, TH, 5.4 ± 1.3%, and SH+B, 5.5 ± 1.2%). In addition, the fasting glucose of trained groups (TH, 106.0 ± 4.5, and TH+B, 100.4 ± 13.5 dL/mg) was significantly lower when compared with controls (SH, 120.0 ± 14.4, and SH+B, 119 ± 6.4 dL/mg) (P < .05). Bocaiuva combined with an HPD reduced visceral fat and AI in addition to improving glucose tolerance of rats submitted to RT.

High-performance circular sawing of AISI 1045 steel with cermet and tungsten carbide inserts
A. M. Abrão,M. C. Moreira,P. E. Faria,J. C. Campos Rubio 대한기계학회 2014 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.28 No.10
This work investigated the influence of cutting speed and feed rate on cutting forces, surface roughness, and slot width circular sawingof AISI 1045 steel. The effects of tool material (cermet and tungsten carbide) and geometry (chip breaker flute and pre-cutting/postcuttingteeth) were also investigated. Thrust and radial forces generally tended to decrease as the cutting speed increased and tended toincrease with the feed rate. The lowest values of thrust and radial forces were obtained using a tungsten carbide saw ground with precuttingand post-cutting teeth. With regard to the quality of the machined wall, the lowest surface roughness was obtained by applying thehighest cutting speed and lowest feed rate and employing a cermet brazed saw. Under this condition, roughness values comparable toface turning and parting off operations were obtained. The cermet brazed saw was responsible for producing the narrowest slot widths.

Antimicrobial Activity of Benzophenones and Extracts from the Fruits of Garcinia brasiliensis
F.J. Naldoni,A.L.R. Claudino,J.W. Cruz Jr.,J.K. Chavasco,P.M. Faria e Silva,M.P. Veloso,M.H. Dos Santos 한국식품영양과학회 2009 Journal of medicinal food Vol.12 No.2
The pericarp and seeds from fruits of Garcinia brasiliensis were subjected to extraction with hexane and ethanol. The pericarp hexane extract (PHE) and seed ethanol extract (SEE) were purified by silica gel column chromatography, which permitted isolation of the prenylated benzophenones 7-epiclusianone (1) and guttiferone-A (2), respectively. The antimicrobial activity of PHE, SEE, and compounds 1 and 2 were evaluated against Candida albicans, Staphylococcus aureus, Escherichia coli, and Bacillus cereus cultures. The minimum inhibitory concentration and minimum bactericidal concentration were established. The substances presented activity against S. aureus and B. cereus as follows: PHE, 4.0 μg/mL and 2.4 μg/mL; SEE, 10.0 μg/mL and 12.6 μg/mL; 7-epiclusianone, 1.2 μg/mL and 0.6 μg/mL; and guttiferone-A, 2.4 μg/mL and 2.4 μg/mL, respectively. The direct relationship between the lipophilic character of the structure and activity in Gram-positive bacteria was specifically observed. Therefore these extracts and prenylated benzophenones represent an interesting topic for further studies and open possibilities for an alternative control of diseases associated with Gram-positive bacteria.
