Abstract
Activated B-cell (ABC) lymphoma, a distinct molecular entity within diffuse large B-cell lymphoma (DLBCL), remains highly incurable, showing a worse response to standard immunochemotherapy. The discouraging results obtained in several clinical trials using proteasome inhibitors, tyrosine kinase inhibitors, or immunomodulators, lead to an intense search for new, potentially druggable biomarkers in DLBCL. In this study, we designed an experimental strategy for DLBCL to discover high- and low-abundance RNA-seq-derived transcripts involved in the oncogenic phenotype in patients diagnosed with ABC-DLBCL. Based on the results of a comparative analysis, 79 DE genes and two enriched gene sets related to metabolism and immunity were selected. Genes related to drug resistance, anti-inflammatory response, and tumor-cell dissemination were found to be up-regulated, while tumor suppressor genes were down-regulated. Then, we searched for the perturbagens most suitable for gene expression profiling (GEP) by iLINCS-CMap. Herein, we present a novel experimental approach that connects the omics signature of DLBCL with potential drugs for more accurate treatments.

Abstract
Millions of patients suffer yearly from bone fractures and disorders such as osteoporosis or cancer, which constitute the most common causes of severe long-term pain and physical disabilities. The intrinsic capacity of bone to repair the damaged bone allows normal healing of most small bone injuries. However, larger bone defects or more complex diseases require additional stimulation to fully heal. In this context, the traditional routes to address bone disorders present several associated drawbacks concerning their efficacy and cost-effectiveness. Thus, alternative therapies become necessary to overcome these limitations. In recent decades, bone tissue engineering has emerged as a promising interdisciplinary strategy to mimic environments specifically designed to facilitate bone tissue regeneration. Approaches developed to date aim at three essential factors: osteoconductive scaffolds, osteoinduction through growth factors, and cells with osteogenic capability. This review addresses the biological basis of bone and its remodeling process, providing an overview of the bone tissue engineering strategies developed to date and describing the mechanisms that underlie cell-biomaterial interactions.

Abstract
Epilepsy affects more than 40 million people worldwide, constituting one of the most debilitating disorders of the central nervous system (CNS). It results from an imbalance in the electrical activity of neurons, which is primarily mediated by calcium ions. In many cases, treatment with antiepileptic drugs (AEDs) that regulate calcium channel activity results in successful seizure control. However, AEDs frequently cause adverse effects that range in severity from minimal impairment of the CNS to death from aplastic anemia or hepatic failure. Moreover, 30% of epileptic patients show drug-resistant epilepsy and do not respond to any form of medical treatment. In this context, nanotechnology has emerged as an excellent tool to overcome AEDs limitations. Numerous nano-strategies have been proposed as therapeutics and diagnostics for epilepsy through inhibition of different calcium channel types in the brain. In addition, limited brain access of classical AEDs in patients showing refractory epilepsy could be improved through the design of targeted drug delivery nanosystems. This report presents a review of the nanocarriers developed so far that could facilitate the interaction with calcium channels in the brain and the transport of AEDs through the blood-brain-barrier, mapping out a potential future direction in the research of epilepsy treatment.

Abstract
Lipases from Candida antarctica (isoform B) and Rhizomucor miehei (CALB and RML) have been immobilized on octyl-agarose (OC) and further coated with polyethylenimine (PEI) and dextran sulfate (DS). The enzymes just immobilized on OC supports could be easily released from the support using 2% SDS at pH 7, both intact or after thermal inactivation (in fact, after inactivation most enzyme molecules were already desorbed). The coating with PEI and DS greatly reduced the enzyme release during thermal inactivation and improved enzyme stability. However, using OC-CALB/RML-PEI-DS, the full release of the immobilized enzyme to reuse the support required more drastic conditions: a pH value of 3, a buffer concentration over 2 M, and temperatures above 45 °C. However, even these conditions were not able to fully release the thermally inactivated enzyme molecules from the support, being necessary to increase the buffer concentration to 4 M sodium phosphate and decrease the pH to 2.5. The formation of unfolded protein/polymers composites seems to be responsible for this strong interaction between the octyl and some anionic groups of OC supports. The support could be reused five cycles using these conditions with similar loading capacity of the support and stability of the immobilized enzyme.
