There currently remains considerable variability in stroke survivor recovery. To address this, developing individualized treatment has become an important goal in stroke treatment. As a first step, it is necessary to determine brain dynamics associated with stroke and recovery. While recent methods have made strides in this direction, we still lack physiological biomarkers. The Virtual Brain (T...
Cod fillets (Gadus morhua) were packed under modified atmospheres, with four different gas compositions (60% CO2-10% O2-30% N2, 60% CO2-20% O2-20% N2, 60% CO2-30% O2-10% N2, 60% CO2-40% O2), and stored at 6 degrees C. Plate counts were carried out after 3, 4, 5, 6 and 7 days, to follow the growth of aerobic and anaerobic bacteria, lactic acid bacteria, H2S-producing bacteria and Enterobacteriac...
A novel and rich protein source was utilized in bonito fillets to prevent/ delay deterioration during frozen storage at -18±1°C. Accordingly, trout wastes hydrolysates (PH); produced enzymatically traditional hydrolysate (TPH) ultrasound–treated (UPH) containing 86.40 g/100 g 86.75 respectively used as a coating. Hydrolysates were mixed with glycerol (2:1) form coating materials. Three groups o...
This study is focused on the effect of phycobiliprotein extraction Gracilaria quality common carp burgers, and application nanoliposomes containing pigment in improvement its antimicrobial antioxidant activity burgers during refrigerated storage 18 days. Burgers were incorporated with liposomal (2.5% 5% w/w), their chemical microbial changes terms pH, peroxide value (PV), thiobarbituric acid (T...
In relation to consumer demand, crustaceans and cephalopods are sold as both fresh and defrosted. It is well known that total volatile basic nitrogen (TVB-N) and volatile amine values, especially, biogenic amines and biogenic amine index, are expression of freshness of fish products, but there is a lack of knowledge of their acceptability limits, for crustaceans and cephalopods. In order to ass...
Host susceptibility to subgroup B, D, and E avian leukosis viruses (ALV) is determined by specific alleles of the chicken tvb locus. Recently, a chicken gene that encodes a cellular receptor, designated CAR1, specific for subgroups B and D ALV was cloned, and it was proposed that this gene was the s3 allele of tvb (J. Brojatsch, J. Naughton, M. M. Rolls, K. Zingler, and J. A. T. Young, Cell 87:...
Avian leukosis virus (ALV) is an oncogenic virus causing a variety of neoplasms in chickens. The group of avian leukosis virus in chickens contains six closely related subgroups, A to E and J. The prevalence of ALVs in hosts may have imposed strong selective pressure toward resistance to ALVs infection. The tvb gene encodes Tvb receptor and determines susceptibility or resistance to the subgrou...
Cypermethrin is a potential toxic pollutant that directly threatens the aquatic ecosystems and environment. Propolis, a natural product collected from plants by honey bees has many functions, such as antimicrobial, antioxidant, and anti-inflammatory. This study attempted to detrmine some biochemical and microbiological parameters of rainbow trout fillets after exposure to propolis and cypermet...
Changes in bacterial community composition and counts of chilled pork during storage at 4 °C were unraveled by culture-dependent method culture-independent method. Physical chemical analyses including drip loss, total volatile basic nitrogen (TVB-N), pH, surface color also performed to estimate its quality shelf life. A 37 phyla, 575 genera 843 species identified all samples high-throughput seq...
هدف از این پژوهش مقایسه اثر عصاره برگ زیتون و زیره سبز در غلظتهای 1 و 2 درصد بر افزایش ماندگاری فیله ماهی کپور نقرهای در دمای C°4 بود. به این منظور شاخصهای تیوباربیتوریک اسید (TBA)، بازهای نیتروژن فرار (TVB-N)، pH، باکتریهای سرما دوست (PTC)، باکتریهای مزوفیل (TVC) و همچنین ویژگیهای حسی فیلههای ماهی کپور نقرهای در روزهای صفر، 4، 8، 12 و 16 نگهداری در یخچال اندازهگیری شدند. بر اساس نتای...
