Osseointegration of titanium implants in the tibia. Electron microscopy of biopsies from 4 patients

We studied the ultrastructure of bone tissue around implants of pure titanium inserted into the tibia in 4 patients with arthrosis or rheumatoid arthritis. Three main appearances of the interface were noted. First, a close contact between titanium and calcified bone with living osteocytes inside the newly-formed bone was observed in all samples. Secondly, a close contact was also seen between the

Model atmospheres and spectra: The role of dust

Brown dwarf atmospheres form molecules, then high temperature condensates (corundum, titanates, silicates, and iron compounds), and then low temperature condensates (ices) as they cool down over time. These produce large opacities which govern entirely their spectral energy distribution. Just as it is important to know molecular opacities (TiO, H2O, CH4, etc.) with accuracy, it is imperative to un

Role of maxilla 2 and its setae during feeding in the shrimp Palaemon adspersus (Crustacea : Decapoda)

The movements of the basis of maxilla 2 in Palaemon adspersus were examined using macro-video recordings, and the morphology of its setae was examined using both scanning and transmission electron microscopy. The basis of maxilla 2 performs stereotypical movements in the latero-medial plane and gently touches the food with a frequency of 3-5 Hz. The medial rim of the basis of maxilla 2 carries thr

RNA quality in frozen breast cancer samples and the influence on gene expression analysis - a comparison of three evaluation methods using microcapillary electrophoresis traces

Background: Assessing RNA quality is essential for gene expression analysis, as the inclusion of degraded samples may influence the interpretation of expression levels in relation to biological and/ or clinical parameters. RNA quality can be analyzed by agarose gel electrophoresis, UV spectrophotometer, or microcapillary electrophoresis traces, and can furthermore be evaluated using different meth

Recurrent inguinal hernia: randomized multicenter trial comparing laparoscopic and Lichtenstein repair

Background: The optimal treatment for recurrent inguinal hernia is of concern due to the high frequency of recurrence. Methods: This randomized multicenter study compared the short- and long-term results for recurrent inguinal hernia repair by either the laparoscopic transabdominal preperitoneal patch (TAPP) procedure or the Lichtenstein technique. Results: A total of 147 patients underwent surger

Lynch syndrome (hereditary nonpolyposis colorectal cancer) diagnostics

Background Preventive programs for individuals who have high lifetime risks of colorectal cancer may reduce disease morbidity and mortality. Thus, it is important to identify the factors that are associated with hereditary colorectal cancer and to monitor the effects of tailored surveillance. In particular, patients with Lynch syndrome, hereditary nonpolyposis colorectal cancer (HNPCC), have an in

Diamond-Blackfan Anemia: Erythropoiesis Lost in Translation

Popular Abstract in Swedish Min forskning har syftat till att bota och förstå blodbristsjukdomen Diamond-Blackfan anemi (DBA). DBA är en sjukdom som upptäcks under första levnadsåret då barnet uppvisar symptom som trötthet och blekhet, p g a lågt hemoglobin blodvärde (Hb). Det låga blodvärdet beror på att nybildningen av röda blodkroppar är nedsatt. Många DBA patienter är kortväxta, en del har medDiamond-Blackfan anemia (DBA) is a congenital erythroid aplasia that usually presents as macrocytic anemia during infancy. Linkage analysis suggests that at least four genes are associated with DBA of which two have been identified so far. The known DBA genes encode the ribosomal proteins S19 and S24 accounting for 25% and 2% of the patients respectively. This study shows that RPS19 gene transfer
