Chicken embryonic stem cells (ESCs) were separated from blastoderms at stage-X and cultured in vitro. Alkaline phosphatase activity and stage-specific embryonic antigen-1 staining was conducted to detect ESCs. Then, chicken ESCs were transfected with linearized plasmid pEGFP-N1 in order to produce chimeric chicken. Firstly, the optimal electrotransfection condition was compared; the results showed the ...

BACKGROUND: Schizophrenia is associated with various brain structural abnormalities, including reduced volume of the hippocampi, prefrontal lobes and thalami. Cannabis use increases the risk of schizophrenia but reports of brain structural abnormalities in the cannabis-using population have not been consistent. We used automated image analysis to compare brain structural changes ...

[M + Ag](+) ions from cyclic and linear polystyrenes and polybutadienes, formed by matrix-assisted laser desorption ionization (MALDI), give rise to significantly different fragmentation patterns in tandem mass spectrometry (MS(2)) experiments. In both cases, fragmentation starts with homolytic cleavage at the weakest bond, usually a C-C bond, to generate two ...

We propose and compare multiple approaches to automatically process data measured through surface-enhanced Raman scattering (SERS), in the context of intracellular molecule probing. It relies on locally detecting the most relevant spectra to retrieve all data independently through indexing, thus avoiding any pre-filtering which occurs with standard processing methods. We ...

Saturn's moon Titan has a nitrogen atmosphere comparable to Earth's, with a surface pressure of 1.4 bar. Numerical models reproduce the tropospheric conditions very well but have trouble explaining the observed middle-atmosphere temperatures, composition and winds. The top of the middle-atmosphere circulation has been thought to lie at an altitude of ...

Phosphatidyl inositol mannosides (PIMs) are constituents of the mycobacterial cell wall; these glycolipids are known to exhibit potent inhibitory activity toward the LPS-induced production of cytokines by macrophages, and therefore have potential as antiinflammatory agents. In order to simplify the structure of these compounds and facilitate their synthesis, heterocyclic analogs ...

Facial involvement of atopic eczema in young children can be difficult to manage. Chronic scratching and rubbing, combined with parental reluctance to use topical corticosteroids on the face, often results in recalcitrant facial eczema. While wet wraps are a useful management option for moderate/severe atopic eczema involving the trunk and ...

To the Editor: Olesen et al. (Aug. 16 issue)(1) report that in their study, warfarin treatment was associated with a decreased risk of thromboembolic events among patients requiring renal-replacement therapy. In contrast, three large registry studies concluded that in patients with atrial fibrillation who were undergoing hemodialysis, warfarin was associated ...

Autosomal dominant polycystic kidney disease (ADPKD) is the most common progressive hereditary kidney disease. In 85-90 % of cases, ADPKD results from a mutation in the PKD1 gene, and the other 10-15 % of the cases are accounted for by mutations in PKD2. PKD1 and PKD2 encode polycystin-1 and polycystin-2. Polycystin-1 may ...

Articular cartilage contains three functional zones (superficial, middle, deep) characterized by distinct structure, composition and biomechanical properties. One of the unsolved major challenges in cartilage tissue engineering is to produce tissue that mimics the zonal organization of the native articular cartilage. An increasing number of studies aim to design zonal ...

Moyamoya disease (MMD) and atherosclerotic cerebrovascular disease (ACVD) differ in angiographic appearance and probably hemodynamics. Pediatric MMD (PMMD) usually presents with cerebral ischemia, while intracranial hemorrhage is more common in adult MMD (AMMD), suggesting differences in cerebral hemodynamics. We analyzed the cortical flow velocity and direction of recipient arteries using ...

Several countries have adopted strategies for preventing and/or controlling equine viral arteritis based on vaccination and restricting the breeding activities of carrier stallions. However, in some cases, carrier stallions are only identified after they have transmitted virus to a mare. Therefore, a mechanism for separating virus from spermatozoa in the ...
