Aerial photography and satellite imagery of the Petersen ice shelf, Nunavut, Canada, from 1959 to 2012 show that it was stable until June 2005, after which a series of major calving events in the summers of 2005, 2008, 2011 and 2012 resulted in the loss of 61% of the June 2005 ice-shelf area. This recent series of calving events was initiated by the loss of extensive regions of >50-year-old mul...
BACKGROUND Reported concentrations of amyloid beta (1-42) (A beta 42) and tau in cerebrospinal fluid (CSF) differ among reports. We investigated the effects of storage temperature, repeated freeze/thaw cycles, and centrifugation on the concentrations of A beta 42 and tau in CSF. METHODS Stability of samples stored at -80 degrees C was determined by use of an accelerated stability testing prot...
STUDY DESIGN Controlled laboratory study. PURPOSE This study aimed to evaluate the efficacy of platelet-rich plasma (PRP) stored at room temperature (RT), frozen, or after freeze-drying. OVERVIEW OF LITERATURE PRP enriches tissue repair and regeneration, and is a novel treatment option for musculoskeletal pathologies. However, whether biological activity is preserved during PRP storage rema...
Sugarcane can be very susceptible to damage by freezes. Freeze-deteriorated cane can cause problems in processing and sometimes leads to a factory shut-down. This study was undertaken during the 2000/2001 harvest season to assess the cold tolerance performance of six commercial sugarcane varieties and to establish new and more sensitive criteria to measure cold tolerance. Two varieties CP 70-32...
Mangrove has the most important role especially in coastal area. The existence of mangrove habitats Banda Aceh which got decreasing and loss after tsunami disaster 2004. purpose this study was to distribution divided into five (5) sub districts including Jaya Baru, Kuta Alam, KutaRaja, Meuraxa, Syiah Kuala. This changes 2004, began from 2005, 2010, 2015, 2022. main data used are Landsat 5 Senti...
The influence of the freeze-thawing process on the size and lamellarity of multilamellar PEG-lipid liposomes prepared from a mixture of egg yolk phosphatidilcholine (EggPC) and distearoyl phosphatidylethanolamine polyethyleneglycol (DSPE-PEG) 2000 was investigated. Trapped volume measurement, quasielastic light scattering (QELS) and freeze-fracture electron microscopy were used to estimate the ...
Abstract In this work, the advantages and disadvantages of freeze drying microwave were considered analyzed. Experimental data on plums are given. The chemical composition before after freeze-drying was results moisture change, compared.
The effect of freeze-thawing on the size of egg yolk phosphatidylcholine (EggPC) vesicles in the presence of 0-40 mol% distearoylphosphatidylethanolamine-polyethylene glycol 2000 (DSPE-PEG) was studied. Mean diameters of the vesicles fell into a range of 80-150 nm after 10 times freeze-thawing in spite of their original size. In the process of freeze-thawing, two opponent events, one is fission...
A method was developed for freeze-dry stabilization of poliovirus type 3. An ultrafiltration procedure was used to remove salts from infected tissue culture fluid, and the virus was freeze-dried after suspension in an alkaline organic buffer. This method was further tested with other picornaviruses including poliovirus types 1 and 2, coxsackieviruses A9, A20, B2, and B5, echovirus 11, and the e...
The present investigation represents the effect of freeze drying on some properties as acid and bile tolerance of Streptococcus thermophilus MTCC 1938 culture isolated from dairy products. The cell paste obtained from milk based medium was freeze dried with a pressure of 50-100 mtorr for 24h at -40°C. Acid and bile tolerance test exhibited 3.8-4.9 and 3.2-3.8 log counts reduction after freeze d...
