032). After building risk classes I to IV (p  less then  0.0001), mean bRFS was 36.3 months (95% CI 32.4-40.1) in class I (PSA less then  0.8 ng/mL, no BM) and 25.8 months (95% CI 22.5-29.1) in class II (PSA ≥ 0.8 ng/mL, no BM, no VM). LR and/or pelvic LNs caused relapse in classes I and II. Mean bRFS was 16.0 months (95% CI 12.4-19.6) in class III (PSA irrelevant, present BM) and 5.7 months (95% CI 2.7-8.7) in class IV (PSA ≥ 0.8 ng/mL, no BM, present VM). CONCLUSION We developed and internally validated a risk classification for bRFS after PSMA-PET-guided MDT. Patients with PSA less then  0.8 ng/mL and local relapse only (LR and/or pelvic LNs) had the most promising bRFS. PSA ≥ 0.8 ng/mL and local relapse only (LR and/or pelvic LNs) indicated intermediate risk for failure. Patients with BM were at higher risk regardless of the PSA. However, those patients still show satisfactory bRFS. In patients with VM, bRFS is heavily decreased. MDT in such cases should be discussed individually.The correct administered activity of 18F-FCH is 0.1-0.14 mCi/Kg, which is equivalent to 3.7-5.2 MBq/kg.CLINICAL PROBLEM The treatment of intracranial wide-necked bifurcation aneurysms-which account for approximately 26-36% of all brain aneurysms-can be challenging both endovascularly and surgically, as a complete cut-off of the blood flow into the aneurysm should be achieved without disruption of the flow into the bifurcation vessels. Intrasacular flow disruption with the Woven-EndoBridge (WEB) is an innovative technique for the treatment of such aneurysms. This review article discusses various aspects of the treatment of intracranial aneurysms with the WEB device, including indications, aneurysm/device selecting strategies, antiplatelet therapy requirements, procedural technique and potential complications. PRACTICAL RECOMMENDATIONS Intrasacular flow disruption with the WEB device is a safe and effective treatment method for intracranial wide-necked bifurcation aneurysms, especially for patients with ruptured aneurysms, in patients with contraindications for antiplatelet therapy, and for patients in whom clipping is associated with high risks.In Germany at least 8000 and probably up to ca. 14,000 people currently suffer from clinically manifest Huntington's disease (HD). In addition, an estimated 24,000 Germans carry the HD mutation in the huntingtin (HTT) gene and will develop HD during their lifetime. Although HD is a rare neurodegenerative disease, it is currently in the focus of general medical interest clinical trials have begun that provide a rational basis for hope to slow down the so far relentless progression of the disease, ultimately resulting in patients becoming entirely dependent on nursing care. If treatment is started early enough it may be possible to mitigate the clinical manifestation of HD. These innovative therapeutic approaches aim at inhibiting the de novo production of mutant HTT gene products. A first clinical drug trial to demonstrate the efficacy (phase III) of intrathecal antisense oligonucleotides (ASO, active substance RG6042) was started in 2019. Additional clinical studies on alternative treatment approaches with allele-selective ASOs as well as gene therapeutic approaches using RNA molecules and zinc finger repressor complexes are imminent. This article gives an overview of the current gene-selective therapeutic approaches in HD under discussion.BACKGROUND Lipopolysaccharide (LPS)-induced acute kidney injury (AKI) is associated with an abnormal immune response. Accumulating evidence has demonstrated that aquaporin 1 (AQP1) prevents kidney tissue injury in LPS-induced AKI by mediating immune response. However, the underlying mechanisms remain obscure. Macrophages as immune cells with multiple phenotypes are important mediators in tissue homeostasis and host defense. We propose that macrophage polarization is implicated in AQP1-mediated immune response. METHODS Herein we established sepsis-induced AKI model rats through intraperitoneal injection of LPS into Wistar rats to reveal immune mechanism of damage. selleck chemicals llc We also used LPS-induced mouse RAW264.7 cells to elucidate the molecular mechanism of macropage polarization. RESULTS Histopathology showed that renal tubular epithelial cells in the model group were swollen, inflammatory exudation was obvious and the inflammatory factors, interleukin-6 (IL-6) and tumor necrosis factor α (TNF-α) were increased. Western blotting showed PI3K was upregulated in the model group. Serum creatinine and urea nitrogen increased after LPS injection. Renal AQP1 mRNA is downregulated and serum AQP1 protein increased first and then decreased in LPS-induced AKI rats. M2 macrophage markers (Arg-1, CD206) were increased in repair stage. In addition, treatment of murine macrophages (RAW264.7) with AQP1 siRNA resulted in decreased PI3K activation and M2 polarization, but increased IL-6 and TNF-α. Moreover, inhibiting PI3K with wortmannin imitated the results of AQP1 silencing. CONCLUSIONS Macrophage M2 polarization is likely the cellular mechanism underlying the anti-AKI property of AQP1, and PI3K activation is involved in the AQP1-induced M2 phenotype switch.An α2-adrenoceptor agonist, clonidine, is extensively used in both anesthesia and intensive care medicine. However, clonidine may produce pronounced hemodynamic side effects such as hypotension and bradycardia which may limit its usefulness in certain conditions. Fadolmidine is a potent α2-adrenoceptor agonist with different physicochemical properties than clonidine. Here, the effects of fadolmidine and clonidine on analgesia (an increase in thermal skin twitch response latency), sedation, blood pressure, heart rate, respiratory rate, and body temperature were evaluated either up to 8 h after either intrathecal or epidural bolus injections or during a 24-h continuous intrathecal infusion at equipotent analgesic doses in non-anesthetized Beagle dogs. Fadolmidine and clonidine produced a dose-dependent and equipotent maximal antinociception after intrathecal bolus injection (ED50 67 μg and 78 μg, respectively), but the duration of action of fadolmidine was more long-lasting. During the intrathecal infusion, fadolmidine achieved a good analgesic effect without evoking cardiovascular side effects, e.
