Alimentary oligofructose (OF) overload induces acute laminitis in dairy heifers. We examined the correlation between acute bovine laminitis and antioxidant levels by measuring the activities of malondialdehyde (MDA), catalase (CAT), reduced glutathione (GSH), and superoxide dismutase (SOD) in dairy heifers with acute bovine laminitis. A total of 12 clinically healthy non-pregnant Chinese Holstein...

Each year malignant tumors take a devastating toll on people, and among the most feared are brain tumors. Five-year survival rates per adults are disappointing, and mortality rates have not improved during the last 3 decades. Although overall 5-year survival rates have reached to 70% in children and mortality rates have declined 25% since 1970, prognosis is still poor for those inflicted with certain...

In developed countries cancer is the second leading cause of death exceeded only by cardiovascular diseases. There are more than 100 types of cancers that can inflict any part of the body. In 2005, 7.6 million people died of cancer, which constitutes 13% of the 58 million deaths worldwide. In the global population exceeding 6 billion in the year 2002, there were approximately 10.9 million new cancer...

Gliomas are the most common tumors accounting for 49% of all primary brain tumors and ~2% of all new cases of cancer in the United States. Approximately, 18,000 new gliomas are diagnosed each year in the United States and >60% belong to the most malignant grade IV glioblastomas. Most of these tumors are untreatable, and patients survive as an average of <12 months, and 16,000 will die of this...

Tumors of the Central Nervous System

The classification of brain tumors is up-dated using magnetic resonance spectroscopy technology. The role of cellular immortality in brain tumors is reviewed. Tumor to tumor metastases are a common occurrence; for example, , brain metastasis from breast cancer, lung cancer, and renal cancer is discussed. Genetic profiling and treatment (including neurosurgery) of such brain cancers are explained...

Advantages and limitations of biomarkers in gliomagenesis are described. Molecular subtypes of gliomas are detailed. The role played by TP53 gene mutation in the deadliest brain tumor, glioblastoma multiforme, is pointed out. The role of mutations of IDH1 and IDH2, and isocitrate dehydrogenases in malignant gliomas are presented. Metabolic differences in different regions of the glioma tumor are clarified...

Hydrometallurgy > 2002 > 65 > 2-3 > 205-216

The kinetics of the title process have been investigated by the single drop technique for 1-day ageing of the aqueous phase. The flux equations have been derived for three aqueous acidities of 0.10, 1.00 and 5.00 M HCl, respectively, as: J (kmol m ^- ² s ^- ¹ )=10 ^- ⁵ ^. ³ ⁷ (1+0.00036 [Zr(IV)] ^- ¹ ) ^- ¹ [H ⁺ ] [H ₂ ...

Solvent extraction of zirconium(IV) from chloride media by D2EHPA in kerosene

Hydrometallurgy > 2002 > 63 > 2 > 149-158

The apparent equilibrium of extraction of zirconium(IV) from chloride media by D2EHPA in kerosene is found to depend on ageing of the aqueous phase. When the aqueous phase, just after preparation, is used in the extraction study, reproducible results are not obtained. With increasing ageing time, the apparent distribution ratio (D) is increased for a particular set of experimental parameters. The...

This article examines the published evidence in support of the classification of organisms into three groups (Bacteria, Archae, and Eukarya) instead of two groups (prokaryotes and eukaryotes) and summarizes the comparative biochemistry of each of the known histone-like, nucleoid DNA-binding proteins. The molecular structures and amino acid sequences of Archae are more similar to those of Eukarya than...
