Injections of Substances Inducing Apoptosis to Cancer Cells but Stimulation of Normal Cells May Prevent Cancer

Journal of Chemistry and Chemical Engineering 2011年第5期5卷 393-403页

作者： birgit Elisabeth Swenson Tegelformsgatan 4 Moelnda143136 Sweden

Selenium（Se） compounds have prevented and Se-deficiency has induced the initiation of cancer. Se（0）-forming compounds and hydroxy-xanthones have killed cancer ceils but shown beneficial effects to normal cells. They may together be effective in the treatment of cancer. Many enzymes which contain selenocysteine （Secys） can catalyze reactions with reducible oxygen （O2~ 02 or H202）. Experiments strongly support that Se-enzymes are activated by Se（0）, from e.g. selenite, selenodiglutathione, binding to Se（-II） in Secys, forming an electron conducting Se-link to reducible oxygen as a protection against oxidations. Cancer cells, which are energy supported only from fermentation, are not dependent on Se which is why they are more sensitive to toxic effects of Se than normal cells. The energy from fermentation is insufficient for normal cell functions. High doses of Se（0）-containing compounds are toxic in that they form links with thiols （R-S-Se） reducing their reaction rate. The reaction of an SH-enzyme, necessary in fermentation, is impaired. Mangostins （hydroxy-xanthones） induce apoptosis in human cancer ceils but stimulate respiration. The OH-groups are responsible for the effects and the reduction of NADP＋ into NADPH. Fermentation is inhibited as NADP＋ is necessary for the process. Cancer may be treated by injections of Se（0）-forming compounds and hydroxy-xanthones into cancer cells in doses causing apoptosis. However, in diluted form, when meting normal cells, the substances promote the yield of energy by stimulating the electron transference to reducible oxygen. Se（0）-activated Se-links and hydrogen from hydroxy-xanthones hopefully prevent the initiation of cancer.

AIM: To report the long-term outcome of patients after complete ablation of non-neoplastic Barrett's esophagus (BE) with respect to BE relapse and development of intraepithelial neoplasia or esophageal adenocarcinoma. METHODS: In 70 patients with historically proven non neoplastic BE, complete BE ablation was achieved by argon plasma coagulation (APC) and high-dose proton pump inhibitor therapy (120 mg omeprazole daily). Sixty-six patients (94.4%) underwent further surveillance endoscopy. At each surveillance endoscopy four-quadrant biopsies were taken from the neo-squamous epithelium at 2 cm intervals depending on the pre-treatment length of BE mucosa beginning at the neo-Z-line, and from any endoscopically suspicious lesion. RESULTS: The median follow-up of 66 patients was 51 mo (range 9-85 mo) giving a total of 280.5 patient years. A mean of 6 biopsies were taken during surveillance endoscopies. In 13 patients (19.7%) tongues or islands suspicious for BE were found during endoscopy. In 8 of these patients (12.1%) non-neoplastic BE relapse was confirmed histologically giving a histological relapse rate of 3% per year. In none of the patients, intraepithelial neoplasia nor an esophageal adenocarcinoma was detected. Logistic regression analysis identified endoscopic detection of islands or tongues as the only positive predictor of BE relapse (P= 0.0004). CONCLUSION: The long-term relapse rate of non neoplastic BE following complete ablation with high-power APC is low (3% per year).

Chlorophyll levels provide important imrormation about plant growth and physiological plasticity in response to changing environments. The stay-green gene NON-YELLOWING 1 （NYE1） is believed to regu-late chlorophyll degradation during senescence, concomitantly affecting the disassembly of the light- harvesting complex and hence indirectly influencing photosynthesis. We identified Brassica napus acces- sions carrying an NYE1 deletion associated with increased chlorophyll content, and with upregulated expression of light-harvesting complex and photosynthetic reaction center （PSI and PSII） genes. Compar- ative analysis of the seed oil content of accessions with related genetic backgrounds revealed that the B. napus NYE1 gene deletion （bnnyel） affected oil accumulation, and linkage disequilibrium signatures suggested that the locus has been subject to artificial selection by breeding in oilseed B. napus forms. Comparative analysis of haplotype diversity groups （haplogroups） between three different ecotypes of the allopolyploid B. napus and its A-subgenome diploid progenitor, Brassica rapa, indicated that introgres- sion of the bnnyel deletion from Asian B. rapa into winter-type B. napus may have simultaneously improved its adaptation to cooler environments experienced by autumn-sown rapeseed.

Dear Editor,During the last decade,there has been an increase in the usage of dietary protein supplements for bodybuilding,especially among young men who work out in commercial gyms.1 Recently,it was shown that 23 of 24 dietary supplements available in fitness equipment and online shops contained anabolic steroids.2 However,these supposedly pro-androgenic supplements presumably differ from the more commonly used whey and soy protein supplements.3,4 Notwithstanding,both products are listed as dietary supplements rather than medical drugs;thus,they are not rigorously tested,5 do not necessarily list all contents,2 and consequently might contain known and unknown active components3,6.

You Need to Know More to Understand My Scoring on the Survey: Free-Text Comments as Part of a PROM-Survey of Men with Prostate Cancer

Open Journal of Nursing 2016年第5期6卷 365-375页

作者： Senada Hajdarevic birgit H. Rasmussen Per Fransson Department of Nursing Ume&aring University Ume&aring Sweden Department of Health Sciences Lund University Lund Sweden

Prostate cancer and its treatment have long-term implications for men’s lives. We aimed to describe the content, extent, and frequency of written comments to the open-ended question, “Further comments?” in the patient-reported outcome measures questionnaire. During the study period, 897 men participated;372 wrote 747 free-text comments in the questionnaire. These comments were analysed using qualitative content analysis and were grouped into four categories: 1) prostate cancer’s influence on health;2) clarifications of answers to the survey;3) descriptions of well-being despite the cancer;and 4) experiences of care and the need for contact with health care. The distribution of the comments shifted over time. The open-ended question not only allowed the participants to explain their other responses and describe important aspects of their lives during and after treatment, something not normally covered by a questionnaire, but it also indicated their experiences of health care services along the patients’ PC-trajectory. This further raises the issue of including an open-ended item in a forced-choice survey into the ethical realm to ensure that proper care is taken of participants’ answers and thoughts.

Lidar ratio of Asian haze and pollution episodes observed by using a Raman/elastic lidar

引用

Chinese Optics Letters 2012年第B6期10卷 1-4页

作者：陈臻懿刘文清张玉钧 birgit Heese Key Laboratory of Environmental Optics and Technology Anhui Insititute of Optics and Fine Mechanics Hefei 230031 China Institute of Tropospheric Research Leipzig Germany

A combined Raman/elastic backscatter lidar observations is carried out in the Pearl River Delta （PRD） China. The results show the largest lidar ratios of the order of 80 sr in the uplifting boundary layer in 2-3 km during the haze period. In the moderate pollution period, the lidar ratio has an average value of 58 sr. The Angstrom exponent exhibits high values around 1.82, indicating the presence of rather small particles. Different back air mass trajectories and the ambient atmospheric conditions are attributed to the distinct characteristics of aerosol optical properties in the haze and moderate pollution episodes. In the lower layer in the haze period, air masses are mostly advected from southeast coast China. In contrast, the air mass in the moderate pollution observing period passes through northwest China, indicating the combination of some pollution from the Tarim Basin in case of strong convection and the smoke from adjacent fire burning spot in PRD region.
