Introduction: The objective of this work was to investigate the therapeutic effect of a combination of hyperthermia at 43oC exposured for 20, 40, 60 min with 6MeV electron beams at different radiation doses (2, 4, 6 Gy) compared to radiation alone.   Materials and Methods: In this in vitro study, HeLa cells were exposed to either: 6MeV electron beams at diffe...

Historically, to describe numbers, some cultures used bases much larger than our usual base 10, namely, 20, 40, and 60. There are explanations for 60, there is explanation but 40—used in medieval Russia—remains largely a mystery. In this paper, we provide possible all these three bases, an based on the natural need manage large groups of people. We also speculate why different bases.

The aim of this study was to evaluate the stability of color, betaxanthin, and betacyanin pigments in the presence of Cu(II)-dependent hydroxyl radicals (HO•) from ultrasonicated purple cactus pear juice at amplitudes of 40%, 60%, and 80%, in comparison to untreated sample. L* parameter of juice treated at 40% and 80% amplitude for 25 and 15 min, respectively (11.3 and 9.3, respectively), were ...

The effect of ultrasound treatments (40 kHz; 40, 50, or 60°C; 5 10 min) and thermal treatment (90°C; 30 s) on the stability parameters orange-carrot juice were evaluated. Microscopic structure, particle size distribution turbidity analyzed first day. Sedimentation cloudiness evaluated over 22 days storage at 7 25°C. Changes in microstructure disruption cell wall evidenced after 60°C/10 min. was...

The aim of this study was to determine whether the decreased muscle and blood lactate during exercise with hyperoxia (60% inspired O2) vs. room air is due to decreased muscle glycogenolysis, leading to decreased pyruvate and lactate production and efflux. We measured pyruvate oxidation via PDH, muscle pyruvate and lactate accumulation, and lactate and pyruvate efflux to estimate total pyruvate ...

In this study, the authors described evaluation of microwave-assisted reaction conditions for synthesis 4,6-dihydroxyaurone derivatives, including 2’,4’,6’-trihydroxychloroacetophenone (50 W, 65°C and 30 min); 4,6-dihydroxybenzofuran-3(2H)-one 60°C 5 min), 80°C 20-40 min). The optimum procedure was applied to prepare derivatives with different substituents on benzylidene ring.

The high performance liquid chromatographic (HPLC) method for the identification and determination of baicalin (BG), wogonoside (WG), oroxylin-A-glucoside (OG), baicalein (B), wogonin (W), orxylin-A (O), paeoniflorin (PF), glycyrrhizic acid (GL), glycyrrhetinic acid (GA), liquiritin (LG), isoliquirition (ILG), liquiritigenin (L), isoliquiritigenin (IL) and ononin (ON) in Huangqin-Tang [Chinese ...
