This research has resulted in a better understanding of the pain mechanisms involved in the chronic painful Achilles and patellar tendon, and based on these findings new non tendon-invasive treatment methods beneficial for the patients have been invented. This is a mini review showing the background and research that resulted in the highly successful mini surgical treatments for mid-portion Achilles tendinopathy and proximal patellar tendinopathy.展开更多

Ten residents (mean age 80.4 years) at one block were exposed to visual art environmental enrichment in common areas over a period of three months. Thirteen persons (mean age 86.6 years) living in another block played in-house boule. Cornell’s test, Mini-Mental tests (MMT), and face recognition test were performed to assess depression, cognition, and episodic memory, respectively before and after the intervention. The results show that visual art environmental enrichment in common areas and lack of stimulating and guiding dialogues show a change in depression scores in the intervention group (p = 0.018) and the control group (p = 0.009). MMT scores improved only in the control group (p = 0.003). No changes in episodic memory in any of the groups were observed. It could be concluded that in order to obtain a positive result of short term visual art environmental enrichment, guiding art dialogues conducted by nurses, as described in previous research, should be added to visual art environmental enrichment in healthcare settings.展开更多

The objective was to prospectively follow the patients 1-year after surgery. Material: Sixty- four tendons in 47 patients (28 men and 19 women, mean age 52 (+/-12 years) on different activity levels) were in local anaestesia operated with US+CD-guided surgical scraping. In 43/64 tendons, there was also removal of the plantaris tendon. Methods: Questionnaires evaluating activity level, VAS for pain during activity, satisfaction with treatment result, and the SF-36 score (quality of life), were used before and 1-year after surgery. Results: At follow-up, the mean VAS for pain during activity had decreased from 62 (+/-20) before surgery to 15 (+/-15) after surgery (p < 0.001). All patients were satisfied with the result and had returned to full tendon loading activity. There were no complications. Both the physical and psychological parameters in the SF-36 score had improved significantly. Conclusions: For patients with chronic painful midportion Achilles tendinopathy, US+CD-guided surgical scraping, often combined with plantaris tendon removal, seems to be an efficient treatment method to recover physically and psychologically.展开更多

It involves redox-controlled transcriptional regulation of the plastome-encoded genes psaAB （encoding the P700 apoproteins of photosystem I） and psbA （encoding the D1 protein of photosystem II） and requires the action of plastidlocalized kinases. To study the potential impact of phosphorylation events on plastid gene expression during the LTR, we analyzed mustard seedlings acclimated to light sources favoring either photosystem I or photosystem II. Primer extension analyses of psaA transcripts indicate that the redox regulation occurs at the principal bacterial promoters, suggesting that the plastid encoded RNA polymerase （PEP） is the target for redox signals. Chloroplast protein fractions containing PEP and other DNA-binding proteins were purified from mustard via heparin-Sepharose chromatography. The biochemical properties of these fractions were analyzed with special emphasis on promoter recognition and specificity, phosphorylation state, and kinase activity. The results demonstrate that the LTR involves the action of small DNA-binding proteins; three of them exhibit specific changes in the phosphorylation state. Auto-phosphorylation assays, in addition, exhibit large differences in the activity of endogenous kinase activities. Chloroplast run-on transcription experiments with the kinase inhibitor H7 and the reductant DTT indicate that phosphorylation events are essential for the mediation of redox signals toward psaA and psbA transcription initiation, but require the synergistic action of a thiol redox signal. The data support the idea that redox signals from the thylakoid membrane are linked to gene expression via phosphorylation events; however, this mediation appears to require a complex network of interacting proteins rather than a simple phosphorelay.展开更多
