Many neurodegenerative diseases are associated with the abnormal sequestration of disease-specific proteins in the brain, but the events that initiate this process remain unclear. To determine whether the deposition of the beta-amyloid peptide (Abeta), a key pathological feature of Alzheimer's disease (AD), can be induced in vivo, we infused dilute(More)
Transgenic mice (Tg2576) overexpressing human beta-amyloid precursor protein with the Swedish mutation (APP695SWE) develop Alzheimer's disease-like amyloid beta protein (Abeta) deposits by 8 to 10 months of age. These mice show elevated levels of Abeta40 and Abeta42, as well as an age-related increase in diffuse and compact senile plaques in the brain.(More)
Protein misfolding and aberrant polymerization are salient features of virtually all central neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease, triplet repeat disorders, tauopathies, and prion diseases. In many instances, a single amino acid change can predispose to disease by increasing the production and/or changing the(More)
AIMS To compare the efficacy and safety of liraglutide versus sitagliptin as add-on to metformin after 26 weeks of treatment in Chinese patients with type 2 diabetes mellitus (T2DM). METHODS This 26-week open-label, active comparator trial (NCT02008682) randomized patients (aged 18-80 years) with T2DM inadequately controlled with metformin [glycated(More)
The demand for INSULIN is increasing rapidly along with the increased number of diabetic patients. Using the CRE/loxP system, we developed a selective marker-free system without crossing to produce PROINSULIN in transgenic plant. In frame of this approach, the induced promoter pRD29A was isolated from Arabidopsis. The CRE recombinase gene was placed under(More)
The relationship between salt bridges and stability/enzymatic activity is unclear. We studied this relationship by systematic alanine-scanning mutation analysis using the typical M4 family metalloprotease Pseudomonas aeruginosa elastase (PAE, also known as pseudolysin) as a model. Structural analysis revealed seven salt bridges in the PAE structure. We(More)
BACKGROUND Polyunsaturated fatty acids (PUFAs), which contain two or more double bonds in their backbone, are the focus of intensive global research, because of their nutritional value, medicinal applications, and potential use as biofuel. However, the ability to produce these economically important compounds is limited, because it is both expensive and(More)
