Significance of dimers to the size of newly synthesized DNA in UV-irradiated Chinese hamster ovary cells.

Clarkson, J M; Hewitt, R R

DNA synthesized after UV irradiation is smaller than that in unirradiated cells even when pulse-labeling times are increased to compensate for the overall reduction in the rate of DNA replication. By isolating newly replicated DNA, incubating it with dimer-specific endonuclease from Micrococcus lute...

Selenium enrichment pattern in flowering Chinese cabbage, cabbage and asparagus

Mo, H.Z.; Yang Zhu; Zhang, M.

CONCLUSIONS - Within a certain range, selenium accumulation in three studied vegetables was lineally correlated with spraying concentration. However, a too high concentration caused the reduction of vegetable output and damage in quality. - Twice spraying with lower concentration of selenium was a b...

Reduction of endogenous GRP78 levels improves secretion of a heterologous protein in CHO cells.

Dorner, A J; Kaufman, R J; Krane, M G

GRP78 is localized in the endoplasmic reticulum and associates with improperly folded or underglycosylated proteins. The role of GRP78 in secretion was studied in Chinese hamster ovary cells expressing a tissue plasminogen activator (tPA) variant which lacks potential N-linked glycosylation site seq...

Recognition of handwritten Chinese characters by combining regularization, Fisher’s discriminant and distorted sample generation

Leung, KC; Leung, CH

The problem of offline handwritten Chinese character recognition has been extensively studied by many researchers and very high recognition rates have been reported. In this paper, we propose to further boost the recognition rate by incorporating a distortion model that artificially generates a huge...

On Microvascular Inflammation and Intestinal Leakage in Radiation Enteropathy

Röme, Andrada

Gastrointestinal tract damage is an insidious feature in patients undergoing radiotherapy. Microvascular inflammation, including leukocyte and platelet recruitment as well as epithelial barrier dysfunction, are considered to constitute key components in the pathophysiology of radiation-induced enter...

Lower intracellular hydrogen peroxide levels in cells overexpressing CuZn-superoxide dismutase

Teixeira, Henrique D.; Meneghini, Rogerio; Schumacher, Robert I.

Transfection of V79 Chinese hamster cells produced clones in which CuZn-superoxide dismutase (CuZn-SOD) activities were 2.2- to 3.5-fold higher than in the parental cells. An overall reduction of antioxidant enzyme activities and both total and oxidized glutathione levels had been found in these clo...

How transfer of R&D to emerging markets nurtures global innovation performance

Harryson, Sigvald J; Søberg, Peder

In the context of global R&D, we connect literature on knowledge management to a network-based theoretical framework helpful to analyse and explain the impact of globalisation of R&D on innovation performance. This framework is applied to two case companies, both global leaders within their respecti...

Exchange Rate Misalignments and World Imbalances: A Fundamental Equilibrium Exchange Rate Approach for Emerging Countries

Aflouk, Nabil; Jeong, Se-Eun; Mazier, Jacques; Saadaoui, Jamel

Since the mid-1990s, the world imbalances have increased significantly with a large US current deficit facing Asian surpluses, mainly Chinese. Since 2007, a partial reduction of these imbalances has been obtained, largely thanks to production's decreases, without large exchange rate adjustments. The...

Effects of vitamins on chromium(VI)-induced damage.

Sugiyama, M

The effects of vitamin E and vitamin B2 on DNA damage and cellular reduction of chromium(VI) were investigated using Chinese hamster V-79 cells. Pretreatment with alpha-tocopherol succinate (vitamin E) resulted in a decrease of DNA single-strand breaks produced by Na2CrO4, while similar treatment wi...

Effects of nonsense mutations on nuclear and cytoplasmic adenine phosphoribosyltransferase RNA.

Kessler, O; Chasin, L A

We have analyzed Chinese hamster ovary (CHO) cell mutants bearing nonsense codons in four of the five exons of the adenine phosphoribosyltransferase (aprt) gene and have found a pattern of mRNA reduction similar to that seen in systems studied previously: a decrease in steady-state mRNA levels of 5-...

Disaster Reduction Decision Support System Against Debris Flows and Landslides Along Highway in Mountainous Area

Li, Fabin; Wei, Fangqiang; Cui, Peng; Zhou, Wancun

Highways in mountainous areas are easy to be damaged by such natural disasters as debris flows and landslides and disaster reduction decision support system (DRDSS) is one of the important means to mitigate these disasters. Guided by the theories and technologies of debris flow and landslide reducti...

Differential toxicity of mitomycin C and porfiromycin to aerobic and hypoxic Chinese hamster ovary cells overexpressing human NADPH:cytochrome c (P-450) reductase.

Sartorelli, A C; Belcourt, M F; Rockwell, S; Hodnick, W F

Purified NADPH:cytochrome c (P-450) reductase (FpT; NADPH-ferrihemoprotein oxidoreductase, EC can reductively activate mitomycin antibiotics through a one-electron reduction to species that alkylate DNA. To assess the involvement of FpT in the intracellular activation of the mitomycins, tra...

Bone turnover markers and prediction of bone loss in elderly women

Lenora, Janaka

Around 70,000 osteoporosis-related fractures occur in Sweden annually and approximately half of the women in western world will sustain a fragility fracture after the age of 50 years. Fracture preventive efforts require the identification of individuals who are at high risk. Biochemical markers of b...

Are hearing and middle ear statuses at risk in Chinese patients undergoing orthognathic surgery?

Wong, LLN; Samman, N; Whitehill, TL

Orthognathic surgery, which is performed to correct dentofacial abnormalities, has been associated with postoperative reduction in hearing sensitivity and middle ear dysfunction. In this study, the pre- and postoperative hearing status and middle ear function of 37 Chinese subjects who underwent ort...

Agricultural Trade and Rural Poverty in Post-reform China

Liang, Zhicheng

In this paper, by employing Chinese provincial data, we develop a simultaneous equation model to estimate the relationship between agricultural trade and rural poverty in post-reform China. We find that trade liberalization can affect China's poverty both directly through providing the poor with eff...
