Animal sera were screened for an alternative enzyme source of alpha1,3-fucosyltransferase, and the highest activity was observed in chicken serum. A partially purified enzyme fraction almost devoid of coexisting glycosidases was prepared from the chicken serum, and used for the fucosylation of LacNAc compounds. The enzyme reaction was efficient enough to allow the one-pot preparation of designe...

It is well established that the basolateral amygdala is critically involved in the association between an unconditioned stimulus (US), such as a foot shock, and a conditioned stimulus (CS), such as a light, during classic fear conditioning. However, little is known about how the US (pain) inputs are relayed to the basolateral amygdala. The present studies were designed to define potential US pa...

Highlights An integrated GPS/INS/VNS navigation system was developed to improve accuracy. adaptive federal Kalman filter with information distribution factors used fuse information. Detection of seedling row lines achieved based on subregional feature points clustering. A modified rice transplanter as an experimental platform for automatic navigation. Abstract . In this article, global position...

In view of the problems difficulties faced in horizontal planting; high labor intensity, poor operation quality and low economy existing sweet potato bare seedling transplanting technology equipment, combined with agronomic requirements planting transplanting, a transplanter is designed, which can realize multiple processes such as rotary tillage ridging, ditching covering soil standing seedlin...

Telomeres are composed of simple tandem DNA repeats that protect the ends of linear chromosomes from replicative erosion or inappropriate DNA damage response mechanisms. The mammalian Protection Of Telomeres (POT1) protein interacts with single-stranded telomeric DNA and can exert positive and negative effects on telomere length. Of four distinct POT1 homologs in the roundworm Caenorhabditis el...

Case Description-A 4.6-month-old pot-bellied pig was evaluated because of non-weight-bearing lameness (grade 5/5) in the right forelimb of 4 days' duration. Clinical Findings-Clinical and radiographic examination revealed a closed, lateral luxation of the right shoulder joint. Treatment and Outcome-Initial attempts at closed reduction failed to provide adequate stability of the shoulder joint. ...

An eco-friendly synthesis of highly functionalized epoxides and their incorporation into an organocatalytic multicomponent approach are reported. For this, a modified class of diarylprolinol silyl ethers was designed to enable high catalytic activity in an environmentally benign solvent system. The one-pot procedure showed great efficiency in promoting stereoselective multicomponent transformat...
