1. Effect of calcium propionate and monensin on in vitro digestibility and gas production
ABSTRACT An evaluation of the effects of monensin and calcium propionate on the in vitro kinetics of gas production, digestibility, carbon dioxide, and minor gas production on different days was performed using the ruminal fluid from eight Suffolk lamb donors, after receiving additives for 1, 10, and 20 days. Treatments consisted of a control ration of 40% g

2. Parâmetros mecânicos, físicos e químicos na avaliação de mandíbulas de ratos deficientes em esteróides sexuais / Mechanical, physical and chemical parameters in mandible evaluation of sex steroid deficiency rats
The increase in the life expectancy has been raising the occurrence of common degenerative alterations in aging population, as osteoporosis. This systemic disease is also frequent in hypogonadism and affects the bone metabolism, included mandibular bone. The aim of this study was to evaluate how sex steroid deficiency, induced by orchiectomy (ORX) or ovariec

3. Inclusion of organic acids salts or sodium monensin in the starter feed and its effects on rumen development and performance of dairy calves / Inclusão de sais de ácidos orgânicos ou monensina sódica no concentrado inicial e seus efeitos no desenvolvimento ruminal e desempenho de bezerros leiteiros
Dois experimentos foram conduzidos com o objetivo de avaliar o efeito da inclusão de butirato de sódio, monensina sódica ou propionato de cálcio no concentrado inicial, sobre o desempenho, parâmetros sanguíneos e desenvolvimento ruminal de bezerros leiteiros. No primeiro experimento, 24 bezerras recém-nascidas da raça Holandesa foram alojadas em abri

4. Análise bioquímica e equilíbrio ácido-base em Biomphalaria glabrata (Say, 1818), hospedeiro intermediário do Schistosoma mansoni (Sambon, 1907), sob a exposição ao Stryphnodendron polyphyllum (Martius, 1837), planta moluscicida do Cerrado brasileiro.
The state of Goiás represents a high risk to schistosomiasis stablishment area The presence of the intermediate host Biomphalaria sp added to high migration levels of people from endemic regions of the country are evidences that favour the installation of this disease life cycle In this state of Goiás there are reports of high parasitary intensity and even

5. Aditivos químicos e microbianos no controle de perdas e na qualidade de silagem de cana-de-açúcar (Saccharum officinarum L.). / Chemical additives and bacterial inoculants on control of losses and quality of sugar cane (Saccharum officinarum L.) silage.
The objective of this project was to evaluate chemical and microbial additives on ethanol control in sugar cane silages, aiming to decrease dry matter (DM) and nutritional losses during storage. Three laboratory silos trials were conducted to study fermentation process and associated losses, and one additional experiment was carried out to evaluate animal pe

6. Alteration of cytoplasmic Ca2+ in resting and stimulated human neutrophils by short-chain carboxylic acids at neutral pH.
The results reported here indicate that the short-chain carboxylic acids acetate and propionate stimulate cytoplasmic calcium mobilization in human polymorphonuclear leukocytes, while butyrate and lactate do not. Together with the results of previous work, this indicates that there are at least three classes of short-chain carboxylic acids: those which can a

8. Mobilization of dantrolene-sensitive intracellular calcium pools is involved in the cytotoxicity induced by quisqualate and N-methyl-D-aspartate but not by 2-amino-3-(3-hydroxy-5-methylisoxazol-4-yl)propionate and kainate in cultured cerebral cortical neurons.
By using primary cultures of cerebral cortical neurons, it has been demonstrated that the antihyperthermia drug dantrolene protects against cytotoxicity induced by the excitatory amino acids quisqualate (QA) and N-methyl-D-aspartate (NMDA), whereas no effect was observed on cell damage mediated by kainate (KA) or 2-amino-3-(3-hydroxy-5-methylisoxazol-4-yl)pr

9. Proposed role of lactate in germination of hypochlorite-treated Clostridium botulinum spores.
Clostridium botulinum 12885A spores treated with hypochlorite required added DL-calcium lactate for L-alanine germination. Lactate was the active component of calcium lactate. Equimolar concentrations of L-malate, but not of DL-propionate, could replace lactate, suggesting that the alpha-hydroxy acid structure is important. Neither lactate nor malate was an

10. In Vitro Lactate Metabolism by Ruminal Ingesta1
Ruminal ingesta (300 ml) obtained from a fistulated cow fed alfalfa hay (H), 3.6 kg of grain mixture with corn silage fed ad libitum (S), 2.5:1 grain-alfalfa hay mixture (G), or a 2.5:1 grain-alfalfa hay mixture providing 545 g of sodium and calcium lactate daily (L) were incubated for 8 hr with nonpolymerized sodium lactate or 17% polymerized lactic acid ne

11. Changes in lipid composition of Escherichia coli resulting from growth with organic solvents and with food additives.
Cells of Escherichia coli contain an altered fatty acid and phospholipid composition when grown in the presence of sublethal concentrations of a variety of organic solvents and food additives. The diversity of compounds examined which caused these changes indicates that no single catabolic pathway is involved. Many of the observed changes are consistent with

12. A single amino acid determines the subunit-specific spider toxin block of alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate/kainate receptor channels.
Joro spider toxin (JSTX) is one of the most potent antagonists of glutamatergic AMPA/KA (alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate/kainate) receptor channels in invertebrates and vertebrates. A differential blocking effect on certain types of glutamatergic synapses--e.g., parallel and climbing fiber synaptic inputs to rat cerebellar Purkinje neuro
