The osmotic behavior of bovine blastocysts produced in vitro was filmed during exposure to and dilution of cryoprotectant solutions used for vitrification. The relationship between the changes in the diameter of embryos and their subsequent survival was assessed. Embryos collected on Day 6 and Day 7 postinsemination were exposed to 10% glycerol (GLY) for 5 min, 10% GLY + 20% ethylene glycol (EG) for 5 min, and 25% Gly + 25% EG for 30 s, before dilution in 0.85 M galactose and finally in embryo transfer freezing medium (ETF). Embryos that had a higher probability of survival behaved as perfect osmometers, shrinking, reexpanding, or swelling according to an identical pattern, whereas embryos that deviated from this standard usually did not survive. The initial embryo diameter, duration of shrinkage and expansion in 10% glycerol, duration of reexpansion in ETF, and final embryo diameter were clearly predictive of the ability to hatch after culture in vitro. On a given day postinsemination, larger blastocysts were more likely than smaller blastocysts to survive and hatch after exposure to cryoprotectants with or without vitrification. [less ▲]

Pomegranate seeds were osmodehydrated using date juice added with sucrose (final °Brix, 55) as immersion solution. The kinetics of osmotic dehydration showed that the most significant changes of mass transfer took place during the first 20 min of the process, regardless of date juice <br />varieties. During this time, seed water loss and solid gain were estimated to be ∼39% and ∼6%, respectively. After 20 min of the process, the percentage of water loss and solid gain varied slightly and ranged on average close to ∼40% and ∼9%, respectively. During osmotic dehydration, there was a leaching <br />of natural solutes from seeds into the solution, which is <br />quantitatively not negligible, and might have an important <br />impact on the sensorial and nutritional value of seeds and date <br />juices. Both scanning electron microscopy and texture <br />(compression) analysis revealed that osmotic dehydration <br />process induced modifications of seed texture and cell <br />structure. Sucrose was found to be the essential element which <br />influences the texture of seed and the viscosity of date juice. <br />Additionally, natural sugar present in date juice permits <br />substituting 35% of the total quantity of sucrose added to the <br />osmotic solution.

Osmotic dehydration of pomegranate seeds was carried out at different temperatures (30, 40, 50°C) in a 55°Brix solution of sucrose, glucose, and mixture sucrose & glucose (50:50 wt/wt). The most significant changes of water loss and solids gain took place during the first 20 min of dewatering. During this period, seeds water loss was estimated to 46% in sucrose, 37% in glucose and 41% in mix glucose/sucrose solution. The increase of temperature favoured the increase of water loss, weight reduction, solids gain and effective diffusivity. Differential scanning calorimetry data provided complementary information on the mobility changes of water and solute in osmodehydrated pomegranate seeds. The ratio between % frozen water and % unfreezable water decreased from 5 to 0.5 during the process. That involving the presence of very tightly bound water to the sample, which is very difficult to eliminate with this process. It also appeared that glass transition temperature depends on the types of sugar. [less ▲]

The osmotic dehydration of pomegranate seeds was compared using fresh and frozen seeds. The process was carried out at 50C in a 55°Brix solution of sucrose. Freezing pomegranate seeds before osmotic dehydration involved an increase of effective diffusivity and a reduction in dehydration time. The most significant changes of water loss (WL) (46 g/100 g of fresh seeds [FS]) and solids gain (SG) (7 g/100 g of FS) took place during the first 20 min for frozen seeds. After this period, seeds WL and SG ranged on average close to 43 and 8 g/100 g of FS, respectively. Osmotic dehydration was slower starting from fresh fruits but led to a higher rate of WL (62 g/100 g of FS) at the end of the process. Both scanning electron microscopy and texture analysis showed a destruction of cell structure and seed texture during the pretreatment (freezing). The same techniques also revealed a texture/structure modification induced by the osmotic dehydration process [less ▲]

In vitro propagation of cauliflower has generally been achieved through axillary shoot proliferation of curd explants on Murashige and Skoog (MS) medium supplemented with an auxin and a cytokinin. Recently, it has been shown (Vandemoortele 1999) that a soaking in sucrose (-2 MPa for 24 h) of cauliflower curd explants, before culture without any growth regulator, also induced axillary branching. The later procedure avoids the phenomenon of hyperhydricity in the shoots formed. Axillary shooting obtained by the two methods appears to be mediated by modifications of internal cytokinin levels. The osmotic pretreatment did not influence auxin levels, but induced a zeatin and a zeatin riboside levels increase. Curd explants cultured with the usual procedure (on MS medium supplemented with 5 mu mol/L BA and 0.5 mu mol/L NAA) showed a zeatin and zeatin riboside levels increase of the same magnitude and a higher one for isopentenyl adenine and isopentenyl adenosine. The modification of the cytokinin status in the curd explants subjected to a short osmotic pretreatment thus should be less favourable for hyperhydricity. [less ▲]

Between 1980 and 1987, 31 cases of osteitis (n = 9) and/or mediastinitis (n = 22) were observed after 2,801 consecutive aorto-coronary bypasses (1.1%). Three types of treatment were used: 1) sternal debridement with osteosynthesis and continuous mediastinal irrigation (n = 25); 2) sternal and mediastinal debridement with open drainage without osteosynthesis (n = 2); 3) incision and debridement of sternal abscesses (n = 4). The overall mortality was 26% (8/31), i.e. 11% (1/9) for isolated osteitis and 32% (7/22) for mediastinitis. Four factors were statistically associated with infection: reoperation for hemorrhage (19.4%, p less than 0.001); preoperative diabetes (25%, p less than 0.001), postoperative low cardiac output (55%, p less than 0.001), postoperative respiratory insufficiency (45%, p less than 0.001).
