The results stratified by geographic area reflect the different prevalence of HIV infection in the general population, except for India, probably due to the shorter life expectancy of HIV + patients.The German-Australian Hans Bettinger is regarded as one of the most important and influential pathologists of his time. Bettinger's research focused on gynecological pathology, with a particular interest in intersexuality, ovarian and cervical cancer. He received global recognition for his achievements among others, he was a Honorary Fellow at the International Academy of Cytology, the Royal Australian College of Physicians, the Royal College of Pathologists of Australia, the Royal College of Obstetricians and Gynaecologists and a Fellow of the Royal College of Pathologists, London. Far less well-known is German-born Bettinger's role as a victim of Nazism. This significant yet hitherto "blind spot" in Bettinger's life is the focus of this paper. Previously undiscovered archival material from the German Federal Archives in Koblenz, supplemented by documents from the Public Record Office Victoria, Australia, and the University of Melbourne Archives, served as the central sources for this study. This paper reveals that Bettinger, as the husband of a Jewish woman in Nazi Germany, was disenfranchised, and subsequently forced to emigrate. After considerable efforts, he succeeded in building a new life in Australia, where he became the "father of obstetrical and gynecological pathology". In the 1950s Bettinger submitted an application for "reparations" to the Federal Republic of Germany. The legal claim was successful From April 1951 onwards, Bettinger received a substantial pension and was thus officially recognized as a victim of Nazism. He was, however, never able to bring himself to return to Germany, and spent the rest of his life in Australia.

Metallothioneins (MTs) involves in the tumorigenesis and prognosis of various cancers. The biological function and methylation status of MT1E in hepatocellular carcinoma (HCC) remain to be elucidated.

We analyzed differentially expressed genes (DEGs) in tumor tissue samples and normal samples from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) database, and identified the expression levels of MT1E in the HCC. Then, the expression levels and methylation status of MT1E in HCC tissues and cells were validated by qRT-PCR and methylation-specific PCR (MSP). Also, MTT, colony formation, transwell assays, and flow cytometry, as well as xenograft model, were used to assess the biological roles of MT1E in HCC.

Downregulated expression of MT1E was found in HCC tissues, and was notably correlated with an aberrant methylation level of the gene promoter. Moreover, our study verified that MT1E suppressed cell growth in vitro and vivo. Further study demonstrated that MT1E could induce apoptosis and suppress the metastasis of HCC cells.

Our results suggested that epigenetic silencing of MT1E due to promoter hypermethylation could play a vital role in HCC.

This study first evaluates the industry's emission reduction effects across 30 provinces of China. Then, the emission reduction paths of "lagging regions," which fail to meet the 2030 industrial carbon emission reduction target, are optimized based on the two-dimensional perspective of carbon emission efficiency and emission reduction cost. this website This study found that (1) China has exceeded its 2020 industrial carbon emission reduction target. There are 9 potential "lagging regions" that failed to meet their 2020 targets, (2) if the current emission reduction rate is maintained, China is capable of exceeding its 2030 industrial carbon emission reduction target, but there are still 11 "lagging regions," (3) there are clear differences in carbon emission efficiency and shadow price among the "lagging regions," and (4) under the premise of ensuring feasibility and fairness, the three provinces of Liaoning, Guangxi, and Shaanxi can set strict emission reduction targets, while other "lagging regions" can set flexible targets.

In order to introduce the concept of diagnostic reference levels (DRLs) in the national nuclear medicine practice a survey was proposed and completed through all nuclear medicine departments in Croatia. An additional aim was to increase the awareness of importance and full implementation of a comprehensive quality program that includes devices used in the nuclear medicine chain.

Data were collected for more than 30 nuclear medicine single photon emission procedures. National DRLs (NDRLs) as administered activity and also as administered activity per unit mass were calculated in accordance to International Commission on Radiological Protection (ICRP) recommendations. Additionally, effective doses were estimated using conversion factors published by the ICRP.

NDRLs for nuclear medicine single photon emission procedures were proposed. For procedures performed in only one department typical values were presented as reference. Effective doses related to applied radiopharmaceuticals were calculated to estimatization process. One of the drawbacks of the DRL concept in nuclear medicine is the lack of the image quality parameters involved. For this reason, a quantity that considers both radiation protection and image quality should be introduced.At PSI (Paul Scherrer Institute), Switzerland, a superconducting cyclotron called "COMET" delivers proton beam of 250 MeV pulsed at 72.85 MHz for proton radiation therapy. Measuring proton beam currents (0.1-10nA) is of crucial importance for the treatment safety and is usually performed with invasive monitors such as ionisation chambers (ICs) which degrade the beam quality. A new non-invasive beam current monitor working on the principle of electromagnetic resonance is built to replace ICs in order to preserve the beam quality delivered. The fundamental resonance frequency of the resonator is tuned to 145.7 MHz, which is the second harmonic of the pulse rate, so it provides signals proportional to beam current. The cavity resonator installed in the beamline of the COMET is designed to measure beam currents for the energy range 238-70 MeV. Good agreement is reached between expected and measured resonator response over the energy range of interest. The resonator can deliver beam current information down to 0.15 nA for a measurement integration time of 1 s.
