1. Effect of glycerol, n, n-dimethylformamide and n-methyl-2-pyrrolidone on rabbit sperm stored at 4 °C and 16 °C
Abstract Artificial insemination with cooled semen is the most common practice in rabbit farms and any improvement on it helps to increase the efficiency and productivity of rabbit meat farms. Therefore, the aim of this study was to assess whether different cryoprotectant agents (CPA) as glycerol, N, N-Dimethylformamide (DMF) and N-Methyl-2-Pyrrolidone (NMP)

2. Medium-term cryopreservation of rabies virus samples
Introduction The cryopreservation of rabies virus has been described in detail in the literature. To date, little information is available on the use of cryoprotective agents for cold preservation of this virus, and the available data focus only on short-term virus preservation. In this study, we investigated the medium-term cryopreservation of samples of r

3. Efeito crioprotetor de lactose e glicose em cÃlulas fÃngicas imobilizadas em alginato de sÃdio como mÃtodo de preservaÃÃo de culturas. / Cryoprotectant effect of lactose and glucose yeast cells immobilized in calcium alginate as a method for preservation of cultures
Cryopreservation is the method of choice in many banks of microorganisms because it leads to a situation of metabolic dormancy and consequently cultures are stable for long periods. By reducing the temperature may however be formed of ice crystals which tend to cause cell damage to cell damage in turn can be avoided by vitrification process which takes place

4. CRIOPRESERVAÇÃO DE TECIDO OVARIANO CAPRINO: EFICIÊNCIA DE DIFERENTES AGENTES CRIOPROTETORES / OVARIAN TISSUE CRYOPRESERVATION GOAT: EFFICIENCY OF DIFFERENT CRYOPROTECTIVE AGENTS
The cryopreservation of ovarian tissue has been the target of intense study with the purpose of assisting in the technology of assisted reproduction in animals and humans. For the success of cryopreservation, the composition of the freezing solution, especially the intracellular cryoprotectant agent used is of fundamental importance. Thus, this study aimed t

5. Evaluation of different cryoprotective agents in maintenance of viability of Helicobacter pylori in stock culture media
Four different cryoprotective supplemented stock media were evaluated for maintaining better survival and recovery of H. pylori type strain NCTC 11637 at two different maintenance temperatures of -20°C and -80°C after one month preservation as frozen stocks. The spread plate colony count method was used to investigate the recovery rate of H. pylori from eq

6. AVALIAÇÃO CINÉTICA DO SÊMEN DE PIRAPITINGA (Piaractus brachypomus) CONGELADO EM MEIO À BASE DE ÁGUA DE COCO EM PÓ (ACP-104) OU RINGER EM TRÊS MEIOS DE ATIVAÇÃO
The pirapitinga, Piaractus brachypomus (CUVIER, 1818) is a Characidade freshwater fish that inhabits the Amazon and Orinoco River basins. The aim of this study was determinate spermatic motility of cryopreserved sperm of pirapitinga in three different activation solutions. Sperm samples were diluted in four freezing media prepared by a combination of two ext

7. Uso de glicerol, metil-formamida e dimetil-formamida como crioprotetores do sêmen canino / Use of glycerol, methyl-formamide and dimethyl-formamide as cryoprotectants of canine semen
A crescente demanda por biotécnicas reprodutivas em cães tem despertado grande interesse no desenvolvimento de protocolos de congelação de sêmen canino que, associados à correta identificação do momento ótimo para a inseminação, resultem em taxas de fertilidade próximas às da inseminação artificial com sêmen fresco ou resfriado. A grande vant
