25. Bromelain extraction process using revesed miceles / Estudo do processo de extração da bromelina por micelas reversas em sistema de descontinuo
Bromelain is a set of proteolitics enzymes found in vegetables of the Bromeliaceae family, from which pineapple is known more. Bromelain has several uses, alI based on its proteolitics activity. There are the necessity to develop new processes for purification and concentration of these composites, the liquid-liquid extraction by reversed micelles reveals as

27. Estudo quÃmico, fÃsico-quÃmico e farmacolÃgico dos carboidratos presentes no fitoterÃpico ( Xarope MelxiÂ)
Melxi syrup is a phytotherapic produced and commercialized by Hebron Laboratory. It is basically composed by honey and pineapple pulp (Ananas comosus) which is used as expectorant and mucolytic agent. The honey possesses an excellent nutritional quality (vitamins, minerals, high energetic value) and medical properties (antioxidant and antiseptic activities

28. AvaliaÃÃo da toxicidade tecidual de Melxi e bromelina por via oral em ratos
ÂCrude bromelain, an aqueous extract from pineapples, has been sold in health food stores as a nutritional supplement for âdigestive aidâ. It contains a mixture of different proteins, carbohydrates and other components. Cystein proteinases in crude bromelain are called bromelains, they are stem bromelain (EC 3.4.22.32), comosain, ananain (EC 3.4.22.31)

29. Bromelain estraction and purification from pineapple economic viability studies / Analise de viabilidade economica de um processo de extração e purificação da bromelina do abacaxi
Brazil is one of the world?s largest producers of pineapples, its production being the third one in the world. To take advantage of the residues from fruit processing, many studies have been conducted to obtain proteolytic enzymes from them. These proteolytic enzymes are extracted mainly from fig (ficine), papaya (papain), and pineapple (bromelain). Bromelai

30. Extração e recuperação da bromelina em sistemas de duas fases aquosas PEG4000-POLICAJU
Aqueous two-phase system explores the possibility of solutions of two polymers or one polymer and one salt separating into two immiscible aqueous phases, when certain critical concentrations are exceeded. This work was characterised by the KA W ASE recovery index analysis of the bromelain of pineapple juice, using a pulsed column for three sizes of tie lines

31. Effect of temperature and of activators on the extraction process of bromelain / Efeito da temperatura e de ativadores no processo de extração da bromelina
Studies were made on the extraction process of bromelain obtained from the stem of pineapple plant Ananas comosus (L.) Merr. variety Cayenne, with the purpose to evaluate the effect of temperature of the filtration extract, addition of activators and of precipitants agents upon the stability of the proteolytic activity and upon the material balance. The filt

32. Proteolytic Inhibition of Salmonella enterica Serovar Typhimurium-Induced Activation of the Mitogen-Activated Protein Kinases ERK and JNK in Cultured Human Intestinal Cells
Bromelain, a mixture of cysteine proteases from pineapple stems, blocks signaling by the mitogen-activated protein (MAP) kinases extracellular regulated kinase 1 (ERK-1) and ERK-2, inhibits inflammation, and protects against enterotoxigenic Escherichia coli infection. In this study, we examined the effect of bromelain on Salmonella enterica serovar Typhimuri

33. Growth potential of cottonseed culture media for various clinically significant aerobic bacteria.
Enzymatic hydrolysates of various cottonseed flours were prepared with the proteolytic enzymes bromelain, HT-200, Pronase, and trypsin. The growth of various aerobic bacteria of clinical significance in these hydrolysates was compared to that obtained with a standard casein-soybean peptone culture medium, Trypticase soy. The generation times of the majority

34. Bromelain as a Treatment for Osteoarthritis: a Review of Clinical Studies
Bromelain, an extract from the pineapple plant, has been demonstrated to show anti-inflammatory and analgesic properties and may provide a safer alternative or adjunctive treatment for osteoarthritis. All previous trials, which have been uncontrolled or comparative studies, indicate its potential use for the treatment of osteoarthritis. This paper reviews th

35. Polypeptides of the surface projections and the ribonucleoprotein of avian infectious bronchitis virus.
Purified avian infectious bronchitis virus was digested with bromelain (0.7 mg/ml), and the surface projections were removed. Polyacrylamide gel electrophoresis of the polypeptides from these bromelain-treated particles showed that VP1, VP2, and VP5 were missing from the seven polypeptides. VP1 to VP7, that were present in untreated virus preparations. Milde

36. Polyclonal B-cell response to stimulation with Escherichia coli lipopolysaccharide in dietary protein restriction.
The polyclonal B-cell response to Escherichia coli lipopolysaccharide was studied in C57BL/6 mice maintained after weaning on either a moderate protein-restricted diet with 8% casein or a normal diet. After in vitro or in vivo stimulation with the endotoxin, autoreactive and anti-hapten antibody-producing cells were quantitated by direct plaque assay, using
