How DNA Medicines Could Transform Treatment of Glioblastoma Multiforme
Tissues for TCGA were collected from many sites all over the world in order to reach their accrual targets, usually around specimens per cancer type. For this reason the image data sets are also extremely heterogeneous in terms of scanner modalities, manufacturers and acquisition protocols. In most cases the images were acquired as part of routine care and not as part of a controlled research study or clinical trial.
Imaging Source Site ISS Groups are being populated and governed by participants from institutions that have provided imaging data to the archive for a given cancer type.

J Neurol Neurosci Vol. Glioblastoma multiforme GBM is the most common and lethal primary glial neoplasm. This invasive behavior is the most contributing factor for the poor prognosis of this cancer , despite the multimodal treatment with surgery, radiotherapy and chemotherapy. Understanding and targeting the molecular mechanisms regulating glioma invasion and progression may help in identifying novel therapeutic targets for GBM treatment.
Glioblastoma Multiforme GBM is the most aggressive primary glial neoplasm [ 1 ]. Because of its high potential for infiltration and invasion, local control of GBM is difficult with either surgery or radiation therapy. Surgical excisions as wide as hemispherectomy have failed to prevent tumor recurrence or improve survival [ 2 , 3 ]. Understanding and targeting of the invasion pathways has therefore, been focus of numerous experiments and pathological studies.

Mesa translates these specifications to vendor-specific graphics hardware drivers. Proprietary graphics drivers e. An open-source effort to write a Mesa Nvidia driver called Nouveau is mostly developed by the community. Besides 3D applications such as games, modern display servers X. Mesa is hosted by freedesktop. Mesa was subsequently widely adopted, and now contains numerous contributions from various individuals and corporations worldwide, including from the graphics hardware manufacturers of the Khronos Group that administer the OpenGL specification.
For Linux, development has also been partially driven by crowdfunding. Mesa is known as housing implementation of graphic APIs. Mesa implements a translation layer between a graphics API such as OpenGL and the graphics hardware drivers in the operating system kernel. The supported version of the different graphic APIs depends on the driver, because each hardware driver has its own implementation and therefore status.
This is specially true for the “classic” drivers, while the Gallium3D drivers share common code that tend to homogenize the supported extensions and versions. Mesa maintains a support matrix with the status of the current OpenGL conformance   visualized at mesamatrix.
Clinical efficacy of the antitumor agent ONC201 in GBM
Treatment of brain tumours is complex and multifaceted, and it involves many different specialists. Recent advances in translational research and molecular understanding of brain tumours raise hope that new treatments are imminent, and patients should be encouraged to participate in clinical trials. The GP has an important role in patient support and coordination of care. Although glioblastoma multiforme GBM is the most common primary brain tumour, it has an incidence of only 6.

The last decade has seen a crescendo of FDA approvals for immunotherapies against solid tumors, yet glioblastoma remains a prominent holdout. Despite more than 4 decades of work with a wide range of immunotherapeutic modalities targeting glioblastoma, efficacy has been challenging to obtain. Earlier forms of immune-based platforms have now given way to more current approaches, including chimeric antigen receptor T-cells, personalized neoantigen vaccines, oncolytic viruses, and checkpoint blockade.
The recent experiences with each, as well as the latest developments and anticipated challenges, are reviewed. T he last decade has seen a crescendo of FDA approvals for immunotherapies against solid tumors, including melanoma and carcinomas of the lung, breast, prostate, bladder, and kidney renal cell. Glioblastoma GBM , however, remains a prominent holdout. It may seem, then, that GBM is simply a latecomer to the immunotherapeutic stage; however, the opposite is true. While, admittedly, the very first cancer vaccines were pitted against sarcomas by William Coley in the s, 16 GBM has a long history of study within the realm of tumor immunology.
Pioneers such as Brooks and Roszman were some of the first to examine the interactions of GBM with the immune system even in the early s. Immunotherapeutic modalities for GBM and other cancers now run the gamut, ranging from antibodies to adoptive cell transfers to vaccines to virally based treatments to immune checkpoint blockade.
The current status for many of these will be reviewed below, with a focus on T-cell—based platforms. Strategies for the direct enlistment of T cells, most simply, have included adoptive lymphocyte transfer ALT , whereby autologous T cells are harvested; trained, expanded, and activated ex vivo against tumor; and transferred back into patients.

Better technology is rekindling the promise of DNA medicines in oncology, including the treatment of glioblastoma. By grade school, most of us have a basic understanding of DNA, or deoxyribonucleic acid, the essential building block of human life. DNA medicines, however, are less well known and historically have been unsuccessful in delivering what 25 years ago was touted as a revolution in therapeutics.
Until now. A recent resurgence of DNA medicines is due in large part to improvements in the technology that has enabled their reintroduction into the clinic. Over the past several years, Inovio, a small biotechnology company outside of Philadelphia, has begun to master the utility of DNA medicines and to optimize their delivery for clinical use in treating and preventing human disease.
Inovio is currently investigating its DNA medicines using a proprietary platform that couples optimization of DNA plasmids with effi cacy-enabling delivery through the use of a smart device known as Cellectra Figure 1, Cover to treat and protect people from precancer, cancer, and infectious diseases. This device uses a short electrical pulse to open pores in the cell, allowing plasmids to enter.
This ensures efficient delivery of the DNA medicine, overcoming limitations of earlier approaches. Most recently, the company has received signifi cant media coverage for INO, a DNA vaccine designed in 3 hours and brought from the bench to the clinic in 83 days to support the fight against coronavirus disease The proprietary technology uses a computer algorithm to build DNA medicines that can target almost any antigen that can be presented to the human immune system through the major histocompatibility class I system.
DNA medicines are built in the form of circular strands of synthetic DNA called plasmids, which can neither propagate nor integrate into the human genome.

Follow me on twitter bradleyboehmke. Gradient boosted machines GBMs are an extremely popular machine learning algorithm that have proven successful across many domains and is one of the leading methods for winning Kaggle competitions. Whereas random forests build an ensemble of deep independent trees, GBMs build an ensemble of shallow and weak successive trees with each tree learning and improving on the previous.
This tutorial will cover the fundamentals of GBMs for regression problems. This tutorial serves as an introduction to the GBMs. This tutorial will cover the following material:. This tutorial leverages the following packages. Some of these packages play a supporting role; however, we demonstrate how to implement GBMs with several different packages and discuss the pros and cons to each.
Important note: tree-based methods tend to perform well on unprocessed data i. In this tutorial I focus on how to implement GBMs with various packages. Although I do not pre-process the data, realize that you can improve model performance by spending time processing variable attributes. Several supervised machine learning models are founded on a single predictive model i.
Alternatively, other approaches such as bagging and random forests are built on the idea of building an ensemble of models where each individual model predicts the outcome and then the ensemble simply averages the predicted values.

It explains how the Committee for Medicinal Products for Human Use CHMP assessed the medicine to reach its opinion in favour of granting a marketing authorisation and its recommendations on the conditions of use for Temodal. Temodal is a medicine that contains the active substance temozolomide. It is available as capsules 5 mg, 20 mg, mg, mg, mg and mg and as a powder to be made up into a solution for infusion drip into a vein.
Temodal is an anticancer medicine. It is used to treat malignant glioma brain tumours in the following groups of patients:. Treatment with Temodal should be prescribed by a doctor with experience in the treatment of brain tumours. The dose and the number of doses depend on the type of tumour being treated, whether the patient has been treated before, whether Temodal is being used alone or with radiotherapy, and how the patient responds to treatment. Temodal capsules should be taken whole without food.
If the solution for infusion is used, it should be given over a period of 90 minutes. Patients may also need to take medicines to prevent vomiting before taking Temodal. For full details, see the summary of product characteristics also part of the EPAR. The active substance in Temodal, temozolomide, belongs to a group of anticancer medicines called alkylating agents.
In the body, temozolomide is converted to another compound called MTIC.
