Developing the controlling techniques for dose loads in patients has led to the introduction of methods for evaluating the new dosimetric value an effective dose. When it is determined, regular refinement of calculating multiples causes errors as hundredths of a percent. Therefore, in addition to tabulated techniques of evaluating the effective dose and direct measurement of the dose absorbed per radiation area, one can determine midpoint exposure of an X-ray feeding device and use a translating program implemented in the Indor-C indicating device designed by the authors. In going from 60 kW to 120 kW, changes in the superficial dose by 15-50%, the absorbed dose by 10-45%, the 5-cm depth dose by 3-5 times can be neglected.

Department of Gynecology, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100021, P. R. China.
Recent research has demonstrated that activating the cGAS-STING pathway can enhance interferon production and the activation of T cells. A manganese complex, called TPA-Mn, was developed in this context. The reactive oxygen species (ROS)-sensitive nanoparticles (NPMn) loaded with TPA-Mn are developed.

Objective: Systemic lupus erythematosus (SLE) and Sjögren disease (SjD) are autoimmune diseases with significant female predominance. The prevalence of SLE is increased in Klinefelter syndrome (KS) compared with the general male population. Our study investigates the dose effects of extra X chromosomes on the development of SLE and SjD in KS and triple X syndrome compared with the general population.

Seaweeds have been utilized as food, fodder, fertilizer, and medicine since ancient times; nevertheless, they have received only a little attention. In the current work, we extracted the sulfated polysaccharide from a marine source and investigated its anti-arthritic potential . The isolated and freeze-dried polysaccharide was tested for acute oral toxicity based on OECD 423.

A recent study design for clinical trials with small sample sizes is the small n, sequential, multiple assignment, randomized trial (snSMART). An snSMART design has been previously proposed to compare the efficacy of two dose levels versus placebo. In such a trial, participants are initially randomized to receive either low dose, high dose or placebo in stage 1.
