parkinsonism is used to describe a syndrome manifested by any combination of six cardinal features: tremor at rest, rigidity, bradykinesia, loss of postural reflexes, flexed posture and the freezing. decreased dopaminergic neurotransmission in the basal ganglia is the core biochemical pathology in parkinsonism. hereditary parkinsonism includes various heredodegenerative diseases such as hallerv...

Preservation of bacteria at the temperature of dry ice (-78.5 C) is a particularly valuable method for the maintenance of such organisms as Treponema pallidum which otherwise require continuous animal-to-animal passage. Turner (1938), Turner and Fleming (1939), and Turner and Brayton (1939) demonstrated that at the temperature of dry ice T. pallidum and relapsing fever spirochetes retain their ...

Different kinds of freezing-point regulators were evaluated to expand the freezing point zone of large yellow croaker, and several treatment methods such as ordinary atmospheric pressure, vacuum environment and injection during the process of penetration were compared to reveal the relationship of diffusion velocities, diffusion time and freezing point of the large yellow croaker. Results obtai...

Background Freezing is considered the most suitable technological treatment to avoid Anisakis infection from eating raw or undercooked fish but modifications of their cuticles upon freezing may reduce resistance gastric fluids, provoking a greater release allergens. This work aimed study relationship between freezing-induced simplex s.l., antigen recognition, and oral digestion in spiked mince....

Freezing stress affects the geographic distribution, growth, and development of potato, resulting in yield loss. Solanum malmeanum, a diploid wild species with strong freezing tolerance, was fused sensitive dihaploid S. tuberosum by somatic hybridization. In our study, 980 calli were obtained, 248 differentiated shoots obtained from calli. Parental-specific SSR markers used to analyse chromosom...
