1. OTIMIZAÇÃO E VALIDAÇÃO DE MÉTODO ENZIMÁTICO SEMIQUANTITATIVO SIMPLES E DE BAIXO CUSTO PARA A BUSCA DE INIBIDORES DE CISTEINO PROTEASES
Cysteine proteases are an important class of enzymes involved in several essential biological processes. For this reason, these enzymes are important therapeutic targets, and therefore can be used in enzymatic assays for the search of hits. The most widely used methods in the search of enzyme inhibitors are spectrophotometric, however they have relatively hi

2. [PROVISIONAL] Boundaries in metagenomic screenings using lacZα-based vectors
Article Metagenomics approaches have been of high relevance for providing enzymes used in diverse industrial applications. In the current study, we have focused on the prospection of protease and glycosyl hydrolase activities from a soil sample by using the lacZα -based plasmid pSEVA232. For this, we used a functional screen based on skimmed milk agar and a

3. Fatty Acid Determination in Fermented Milk Samples Employing Direct Esterification and Gas Chromatography
The developed method (DM) allows to perform experiments in shorter time with reduced amount of sample and reagent for fatty acids (FA) determination in fermented milk samples. Design Expert software was employed to discover the greatest sonication time (7 and 20 min) and concentration for alkaline and acidic reactions (0.70 and 1.5 mol L-1). Validation proce

4. Variation of cow’s milk composition across different daily milking sessions and feasibility of using a composite sampling
RESUMO: Este estudo visou detectar possíveis mudanças na composição química e celular do leite de vaca em diferentes sessões de ordenha, e testar se a amostragem de leite proporcional ou composta pode ser usada em vez de uma análise separada do leite. Dois experimentos foram conduzidos: um em vacas ordenhadas três vezes ao dia e outro em vacas orden

6. Results from portable and of low cost equipment developed for detection of milk adulterations
Abstract This work presents the results of a device, MilkTech, developed to detect milk tampering, based on electrical measurements. The device indicates possible frauds by water, sodium chloride, caustic soda, ethyl alcohol and sodium bicarbonate. The advantages in relation to traditional methods are portability, low cost and detection of mixed frauds. The

7. Optimization of synbiotic yogurts with yacon pulp (Smallanthus sonchifolius) and assessment of the viability of lactic acid bacteria
Abstract The aim of this study was check the effects of sugar, yacon pulp and skimmed milk powder in the aroma, flavour, texture, appearance, overall impression and intent to purchase on synbiotic yogurts to optimize the formulation using Response Surface Methodology. The most accepted formulations were subjected to viability tests during 21 days by counting

8. Rapid and Highly Sensitive Determination of Melamine in Different Food Samples by Corona Discharge Ion Mobility Spectrometry after Dispersive Liquid-Liquid Microextraction
In this work, for the first time, a highly sensitive method based on dispersive liquid-liquid microextraction coupled with positive corona discharge ion mobility spectrometry as a fast and inexpensive technique has been evaluated for the direct determination of melamine. The effective parameters influencing the microextraction efficiency, such as pH, the pro

9. Metaanálisis del uso de semillas y aceites en la dieta de ovejas y cabras
Abstract:The objective of this work was to use meta-analysis to study the productive results of ewe and goat fed oil and seed, rich in unsatured fat acid. Twenty-two experiments with ewes (63 treatments) and 21 experiments with goats (76 treatments) were used. Average extra fat intake was 83.6±33.6 g per day in ewes, and 73.4±38.7 g per day in goats. In ew

10. Factors affecting feed efficiency in dairy goats
The objective of this study was to present some factors affecting feed efficiency in dairy goats. To develop our work, individual and average data from performance experiments with lactating goats were used. The following variables were evaluated: gross feed efficiency, adjusted feed efficiency, dry matter intake, milk-yield, 3.5% fat-corrected milk yield, d

11. Quantitative characterization of corn plant components according to planting time and grain maturity stage
The objective of this experiment was to characterize the dry matter production of vegetative components (stalk, leaf, husk, and cob) and reproductive components (grain) of the corn plant according to planting time and the grain maturity stage. Eight corn hybrids with different agronomic characteristics were used to carry out the experiments. Two experiments

12. Evaporative cooling for lactating sows under high ambient temperature
Two experiments were conducted to evaluate the evaporative cooling of the air at farrowing on the performance of lactating sows under high environmental temperature conditions in the Central West region of Brazil. One hundred and forty-four lactating sows - 46 of first and second farrowing (experiment I) and 98 from the third to eighth farrowing (experiment
