Scientific knowledge about the predispositions of Bosnian native breeds of sheep (Dubska) for the production of milk and milk products until recently were quite sparse and very scarce. Therefore, the aim of this study was to investigate the biochemical indicators and serum minerals, for monitoring the nutritional status. Until now subject research did not include testing of the effect of biochemical parameters and hormonal status of the blood of sheep on the quality of milk and milk products. Persistence of this connection is justified by the fact that most of the ingredients of milk just derived from the blood. The main objective of this research was to explore metabolic parameters of sheep’s blood, and their relative importance on the quality and quantity of milk components. The study included a total of 127 sheep blood samples from two different areas (Livno and Travnik) in summer feeding period (July, August and September). The animals were marked with the appropriate number of ear tags on the basis of which we always took samples from the same animals through different periods. In sheep blood serum, the concentration of biochemical parameters (glucose, cholesterol, triglycerides, total protein, albumin, urea, AST, ALT, AP, GGT, LDH, calcium, phosphorus and magnesium) and metabolic hormones (triiodothyronine, thyroxine, and insulin cortisol), and samples of milk: milk parameters (milk fat, lactose and protein) as well as fatty acid composition of the milk. The concentrations of blood biochemical parameters were determined by spectrophotometry with automated analysis with ready-made package of slides. Concentrations of metabolic hormones (T3, T4, cortisol and insulin) in the serum were determined by ELISA method. The percentages of fat, protein and lactose in milk were determined by infrared spectrophotometry. Fatty acids in milk were determined by gas chromatography (GC). Our research showed hypoglicemia, mild hypoproteinemia and hypoalbuminemia probably due to

The ilama tree (Annona diversifolia Saff.) is an underutilized fruit species from Mesoamerica with a noteworthy variability in southern Mexico. The present study describes differences in knowledge and appreciation of the fruit among inhabitants from different communities in Southern Mexico, as well as differences among their ilama trees. The study took place in Tierra Caliente, a region located in the states of Guerrero and the State of Mexico. Interviews were administered in three different communities as an attempt to associate the natural morphologic variation of plants and locals’ knowledge and use of the tree in order to identify their implications for conservation. Data were analyzed by multivariate analysis, and the results suggest that the morphological variation of the plants and the commercial importance of ilama are well known by locals. Indigenous community inhabitants prefer and select only white pulp trees, whereas mestizo communities promote and conserve plants with white, red, purple, and blue pulp. Germplasm flow is dynamic in the region, and ilama fruit represents a different economic value for each community. Selling the fruit is the primary goal, but not specifically its conservation and promotion. Implications for in situ conservation of ilama in Mexico are discussed.

Knowledge of healing plants worldwide properties it has been extensively studied by their biological activities. The increasing number of plant users for healthcare originated the Research Center in Complementary Alternative Medicine, National Institute of Health (NIH) whose primary function is to be alert with a strictly scientific sense about de use of plants as main source of Complementary Alternative Medicine. It is currently about the synergy known that Is achieved on the hepatoprotective, antioxidant and hypoglycaemic activities with mixtures formed by selected plants and combined. These plants are characterized by their content of hidroxyphenolic compounds as cynarin, rosmarinic acid, flavonoids silybin and among others. Actually this kind of herbal preparations are investigated in patients with cirrhosis, type II diabetes mellitus, breast cancer and arthritis diseases. Patients with Chronic Degenerative Diseases are in state of stress and Its metabolism produces free radicals such as superoxide oO2, hydroxyl oOH and peroxynitrite highly reactive with unsaturated fatty acids of cell membranes producing lipid peroxidation. The main product of this process is the peroxyl, that when it’s reduced forms hydroxiperoxyle its decomposition forms MDA and 4-hidroxialquenal. These substances bind to R-SH2 of the aminoacids of the proteins and to the thymine of DNA, altering their biological function. Before the treatments with selected and micropulverized plants to patients, it is necessary and required in animal models demonstrate that plants do not produce toxic effects. Using mixtures of plants micropulverized is good choice because these microparticles behave as micro-releasing their constituents with increased activity and bioavailability to target cells so it will be possible to achieve greater power to control their activity and perhaps cure the disease, and provide patients an effective herbal medicine safe, free of toxic effects and low cost.

Several protein sources can be used to produce bioactive peptides with angiotensin I-converting enzyme (ACE) inhibittory activity. Protein concentrates from ungerminated and germinated lima bean Phaseolus lunatus seed flours were hydrolyzed with Alcalase 2.4 L or pepsin-pancreatin sequential hydrolysis, and ACE inhibitory activity measured in the different hydrolysis treatments. Protein hydrolysate production was analyzed with a 23 factorial design with four replicates of the central treatment. Evaluated factors were protein concentrate source (ungerminated seeds, PC1;germinated seeds, PC2), enzyme/substrate ratio E/S (1/50 or 1/10) and hydrolysis time (0.5 or 2.0 h for Alcalase;1 or 3 h for pepsin-pancreatin). Degree of hydrolysis (DH) was high for the Alcalase hydrolysates (24.12% 58.94%), but the pepsin-pancreatin hydrolysates exhibited the highest ACE inhibitory activity (IC50 = 0.250 0.692 mg/mL). Under the tested conditions, the hydrolysates with the highest ACE inhibitory activity were produced with sequential pepsin-pancreatin using either PC1 at 1 h hydrolysis time and a 1/10 E/S ratio or PC2 at 1 h hydrolysis time and a 1/50 E/S ratio. Lima bean protein hydrolysates prepared with Alcalase or pepsin-pancreatin are a potential ingredient in the production of physiologically functional foods with antihypertensive activity.

This paper presents the results of the characterization by thermogravimetric analysis of a new composite material called polymeric concrete. The polymeric concrete contains micro-particles obtained from High Density Poly-Ethylene (HDPE) mechanically recycled (post-consumer bottles);the official Mexican standard NMX-E-232-SCFI-1999 considers the HDPE as the recyclable plastic material. Thermo-grams based on weight lost were obtained from the raw material (HDPE) and the polymer concrete in order to obtain the glass transition temperature (Tg) and melting temperature (Tf). The analysis conditions were defined from 20°C to 180°C and the heat rate of 1°C/minute. The results show that the glass transition temperature of polymeric concrete is 46°C and the HDPE is 38°C. These results mean that the polymeric concrete is more resistant to decomposition. With respect to the melting temperature, the results show that the 2°C difference between polymeric concrete and HDPE is not significant. The polymeric concrete with HDPE recycled can be considered as composite material thermoplastic. The new material melts when it is heated to 146°C and has the ability to be softened, processed and reprocessed with temperature and pressure changes, which make it possible to obtain molded pieces in the desired shape.
