background: radio-adaptive response and bystander effects are known phenomena occurring in cells following exposure to ionizing radiation (ir). in this study we examined possible radio-adaptation of lymphocytes following bystander effects induced by cho-k1 cells. materials and methods: whole blood and cho-k1 cells were cultured in rpmi-1640 complete medium. cells were separately irradiated with...

objective: to study the mechanisms involved in amyloid formation processes, we made a mammalian cell culture model of amylin aggregation and characterized its properties. materials and methods: amyloid fibrils were extracted from cho cells and binding affinity to thioflavin t and congo red was investigated. then the apple-green birefringence of extracted fibrils was detected under polarized li...

Short-term alterations in dietary carbohydrate (CHO) energy are known to alter whole-body fuel selection in humans, but the metabolic mechanisms remain unknown. We used stable isotope-mass spectrometric methods with indirect calorimetry in normal subjects to quantify the metabolic response to six dietary phases (5 d each), ranging from 50% surplus CHO (+50% CHO) to 50% deficient CHO (-50% CHO),...

The purpose of the present study was to investigate the aerobic capacity characteristics of an isocaloric carbohydrate (CHO) plus protein (PRO) drink and a low-calorie CHO plus PRO drink against a traditional 6% CHO sports beverage. Twelve male and female trained cyclists exercised on 4 separate occasions at intensities that varied between 55 and 75% V(O2)max for 2.5 hours and then at 80% V(O2)...

background: the optimization of bioprocess conditions towards improved growth profile and productivity yield is considered of great importance in biopharmaceutical manufacturing. peptones as efficient sources of nutrients have been studied for their effect on media development however, their role on metabolic pathway is not well understood. methods: in the present study, the effect of different...

we searched for novel chinese hamster ovary (cho) cell mutants defective in peroxisome biogenesis by an improved method using peroxisome targeting sequence (pts) of pex3p (amino acid residues 1–40)-fused enhanced green fluorescent protein (egfp). from mutagenized tkaeg3(1–40) cells, the wild-type cho-k1 stably expressing rat pex2p and of rat pex3p(1–40)-egfp, numerous cell colonies resistant to...

proteinase 3(pr3) is a human polymorphonuclear leukocyte serine proteinase and is the main target antigen for antineutrophil cytoplasmic antibodies (anca) found in wegener's granulomatosis (wg). we developed a stable expression system for conformationally intact recombinant pr3 (rpr3) in chinese hamster ovary cells (cho-cells). the part of pr3 cdna that encoded the active form of pr3 was s...

CONTEXT Carbohydrate (CHO) and caffeine (CAF) both improve endurance performance. PURPOSE To determine by systematic literature review coupled with meta-analysis whether CAF ingested with CHO (CHO+CAF) improves endurance performance more than CHO alone. METHODS Databases were searched using the keywords caffeine, endurance, exercise, carbohydrate, and performance. Criteria for inclusion wer...
