Neoplastic cells which co-form tumors are usually subjected to various stress factors, mainly hypoxia and shortage of nutrient factors. Such cells employ different strategies that permit their survival under such conditions. Experiments in vitro are usually carried out in the presence of 21% oxygen and medium supplemented with 10% FBS. Altering these parameters can approximate the in vivo condi...

• Optimized ultrafast-laser powder bed processing produces uniform and compact sintered layers of niobium oxide. Microstructure anisotropy the can be controlled with laser conditions. Laser enables stabilizing a monoclinic oxygen-deficient phase. oxygen-deficiency determine electrical properties material. The material resistivity decreases by more than eight orders magnitude upon treatment. In ...

Corn (Zea mays, L.), bean (Phaseolus vulgaris L.), barley (Hordeum vulgare L.), spinach (Spinacia oleracea L.), and sugarbeet (Beta vulgaris L.) grown under iron deficiency, and Potamogeton pectinatus L, and Potamogeton nodosus Poir. grown under oxygen deficiency, contained less chlorophyll than the controls, but accumulated Mg-protoporphyrin IX and/or Mg-protoporphyrin IX monomethyl ester. No ...

Rasburicase is frequently used in tumor lysis syndrome (TLS). Although it is very well tolerated, it can cause severe oxidative hemolytic anemia and methemoglobinemia in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency. We report another case of rasburicase-induced methemoglobinemia in a patient with previously unrecognized G6PD deficiency and review the cases of methemoglobine...

boron (b) is a non-metal micronutrient which is essential for plants growth and development. formation of boron complex with cell wall matrix and phenolic compounds is a definite influence of boron in physiological process. it has been suggested that b-toxicity and deficiency may induce excess production of reactive oxygen species thereby promote defense responses by antioxidant enzymes or non-...
