Elimination of Ehrlich tumours by ATP-induced growth inhibition, glutathione depletion and X-rays

1995

ATP-induced tumour growth inhibition is accompanied by a selective decrease in the content of the tripeptide glutathione (GSH) within the cancer cells in vivo. Depletion of cellular GSH sensitizes tumours to chemotherapy and radiation, but the usefulness of this depletion depends on whether the levels of GSH can be reduced in the tumour relative to normal tissues. We report here that administration of ATP in combination with diethylmaleate and X-rays leads to complete regression of 95% of Ehrlich ascites tumours in mice. This shows that an aggressive tumour can be eliminated by using a therapy based on modulation of GSH levels in cancer cells.

Treatment of soft tissue sarcoma in childhood and adolescence: A report of the german cooperative soft tissue sarcoma study

1992

Background In the first German soft tissue sarcoma (STS) study, CWS-81, 344 patients younger than 19 years of age who had previously untreated soft tissue sarcoma were studied. For this analysis, there were 218 patients with chemosensitive STS (Group A: rhabdomyosarcoma [RMS], synovial sarcoma, extraosseous Ewing sarcoma, leiomyosarcoma, undifferentiated sarcoma, and malignant peripheral neuroectodermal tumor) who could be studied for a minimum potential follow-up time of 6 years. Methods A staging system based on the postoperative extent of the disease was used. The chemotherapy for Stage I-III disease consisted of vincristine, dactinomycin, cyclophosphamide, and doxorubicin (VACA). Patien…

Transgraft sac Embolization Combined with Graft Reinforcement for Refractory Mixed-Type Endoleak.

2018

International audience; An 80-year-old female underwent EVAR 4 years ago. She presented type II endoleak with sac expansion from 68 to 80 mm during 3-year follow-up after EVAR. Although she underwent translumbar percutaneous sac embolization, the AAA sac continued to enlarge, suggesting mixed-type endoleak including type I, II, and III. Transgraft direct sac angiography revealed endoleak cavity without demonstrable feeding vessel. Transgraft sac embolization using n-butyl cyanoacrylate and graft reinforcement was performed concurrently, without complications. The graft reinforcement consisted of graft extension for eliminating occult type I endoleak, and relining for eliminating occult type…

Evaluation of prostate segmentation algorithms for MRI: The PROMISE12 challenge

2014

Contains fulltext : 137969.pdf (Publisher’s version ) (Open Access) Prostate MRI image segmentation has been an area of intense research due to the increased use of MRI as a modality for the clinical workup of prostate cancer. Segmentation is useful for various tasks, e.g. to accurately localize prostate boundaries for radiotherapy or to initialize multi-modal registration algorithms. In the past, it has been difficult for research groups to evaluate prostate segmentation algorithms on multi-center, multi-vendor and multi-protocol data. Especially because we are dealing with MR images, image appearance, resolution and the presence of artifacts are affected by differences in scanners and/or …

Rare association of herpes simplex virus IgM-specific antibodies and Guillain-Barré syndrome successfully treated with plasma exchange and immunosupp…

1985

Herpes simplex virus (HSV) has been associated with various neurological disorders. In contrast, HSV infection is very rarely found in acute polyneuroradiculitis. In this report, a patient is described with a severe course of Guillain-Barr¿ syndrome (GBS). HSV IgM-specific antibodies and a rise of complement-fixation antibodies were detected. During the acute phase of neurologic syndrome, a nerve biopsy showed myelin damage and IgM deposits on the inner layer of the perineurium. Plasma exchange, in combination with immunosuppression, was successfully applied as a treatment in the relapsing course of GBS. Finally, after recovery, HSV-specific IgM antibodies disappeared.

Detrimental Effects of 60 kHz Sonothrombolysis in Rats with Middle Cerebral Artery Occlusion

2008

Recent studies have raised concerns about the safety of low frequency ultrasound in transcranial therapeutic application in cerebral ischemia. This study was designed to evaluate safety aspects and potential deleterious effects of low frequency, 60 kHz ultrasound in treatment of experimental middle cerebral artery occlusion (MCAO) in rats. Forty-five male Wistar rats were submitted to either temporary (90 min; groups I and II) or permanent MCAO (groups III and IV) using the suture technique. All animals received recombinant tissue plasminogen activator (rt-PA) starting 90 min after the beginning of occlusion. Groups I and III were additionally treated with 60 kHz ultrasound (time average ac…

Improving survival with deferiprone treatment in patients with thalassemia major: A prospective multicenter randomised clinical trial under the auspi…

2009

The prognosis for thalassemia major has dramatically improved in the last two decades. However, many transfusion-dependent patients continue to develop progressive accumulation of iron. This can lead to tissue damage and eventually death, particularly from cardiac disease. Previous studies that investigated iron chelation treatments, including retrospective and prospective non-randomised clinical trials, suggested that mortality, due mainly to cardiac damage, was reduced or completely absent in patients treated with deferiprone (DFP) alone or a combined deferiprone-deferoxamine (DFP-DFO) chelation treatment. However, no survival analysis has been reported for a long-term randomised control …

Augmentation of tibial plateau fractures with an injectable bone substitute: CERAMENT™. Three year follow-up from a prospective study

2015

Background: Reduction of tibial plateau fractures and maintain a level of well aligned congruent joint is key to a satisfactory clinical outcome and is important for the return to pre-trauma level of activity. Stable internal fixation support early mobility and weight bearing. The augmentation with bone graft substitute is often required to support the fixation to mantain reduction. For these reasons there has been development of novel bone graft substitutes for trauma applications and in particular synthetic materials based on calcium phosphates and/or apatite combined with calcium sulfates. Injectable bone substitutes can optimize the filling of irregular bone defects. The purpose of this…

The lipid-lowering effects of lomitapide are unaffected by adjunctive apheresis in patients with homozygous familial hypercholesterolaemia – A post-h…

2015

AbstractObjectiveLomitapide (a microsomal triglyceride transfer protein inhibitor) is an adjunctive treatment for homozygous familial hypercholesterolaemia (HoFH), a rare genetic condition characterised by elevated low-density lipoprotein-cholesterol (LDL-C), and premature, severe, accelerated atherosclerosis. Standard of care for HoFH includes lipid-lowering drugs and lipoprotein apheresis. We conducted a post-hoc analysis using data from a Phase 3 study to assess whether concomitant apheresis affected the lipid-lowering efficacy of lomitapide.MethodsExisting lipid-lowering therapy, including apheresis, was to remain stable from Week −6 to Week 26. Lomitapide dose was escalated on the basi…
