Conventional TB drugs are less effective because of poor intracellular delivery to this bacterial sanctuary. This study highlights the potential of using semicrystalline delta inulin particles that are readily internalised by monocytes for a monocyte-based drug delivery system. Pyrazinoic acid was successfully attached covalently to the delta inulin particles via a labile linker. -

Advances in Nanomaterials in Biomedicine
nanomaterials Editorial Advances in Nanomaterials in Biomedicine Elena Ryabchikova Institute of Chemical Biology and Fundamental Medicine, Siberian Branch of Russian Academy of Science, 8 Lavrentiev Ave., 630090 Novosibirsk, Russia; [email protected] Keywords: nanotechnology; nanomedicine; biocompatible nanomaterials; diagnostics; nanocarriers; targeted drug delivery; tissue engineering Biomedicine is actively developing a methodological network that brings together biological research and its medical applications. Biomedicine, in fact, is at the front flank of the creation of the latest technologies for various fields in medicine, and, obviously, nanotechnologies occupy an important place at this flank. Based on the well-known breadth of the concept of “Biomedicine”, the boundaries of the Special Issue “Advances in Nanomaterials in Biomedicine” were not limited, and authors could present their work from various fields of nanotechnology, as well as new methods and nanomaterials intended for medical applications. This approach made it possible to make public not only specific developments, but also served as a kind of mirror reflecting the most active interest of researchers in a particular field of application of nanotechnology in biomedicine. The Special Issue brought together more than 110 authors from different countries, who submitted 11 original research articles and 7 reviews, and conveyed their vision of the problems of nanomaterials in biomedicine to the readers. A detailed and well-illustrated review on the main problems of nanomedicine in onco-immunotherapy was presented by Acebes-Fernández and co-authors [1]. It should be noted that the review is not limited to onco-immunotherapy, and gives a complete understanding of nanomedicine in general, which is useful for those new to this field. -

Although the reasons of low back pain are uncountable, it has been meaningfully related to intervertebral disc degeneration. Present therapies for Intervertebral Disc (IVD) degeneration such as physical therapy and spinal fusion reduce symptoms' severity, but do not treat the source of degeneration. The use of tissue engineering to treat disc degeneration offers a chance to control the pathological course. New methods are presently being examined and have exposed mixed results. One major way of study has been stem cell injections. We go on to define the course of stem cell-mediated modalities in treatment of degenerative lumbar disc herniation Methods & Materials/Patients: Literature search was performed in electronic databases PUBMED and EMBASE by means of Mesh terminologies (Nucleus pulposus, therapeutics, annulus fibrosus, intervertebral disc) and keywords (Degenerative disk disease, Stem Cells, Therapy). Results: The intervertebral disc organization, developing treatments, mesenchymal stem cells, embryonic stem cells, practice in disc degeneration were some sections that were found in analysis for study review design. -
Anti-Aging: Radical Longevity, Environmental Impacts, and Christian Theology
Article Anti-Aging: Radical Longevity, Environmental Impacts, and Christian Theology Anti-Aging: Radical Longevity, Environmental Impacts, and Christian Theology Dorothy Boorse Current biomedical research shows promise for prolonging human life spans. Responses to these possible technologies vary from extreme caution, to exuberance, to a futuristic vision of humanity transforming itself. Bioethicists express concerns about big social and individual costs. Some views are expressed in the rhetoric of a culture war similar to those over cloning, stem cell research, and euthanasia. The possible effect on the environment is unknown. The biggest effect is likely to be on an increase in individual consumption of resources by a few and greater gaps between the rich and the poor. On a number of levels, radical longevity affects our view of self, humans in community, and our role in the natural world. I propose that prolonging human primary life span substantially is not a biblical mandate and is only appropriate when placed in the context of our role as humans and current environmental Dorothy Boorse and social issues. “Our technological abilities have outpaced our moral intuition” —Scholarship applicant, Gordon College 2001. n the 1998 novel The First Immortal,1 to elongate the natural human life span so Understanding Iauthor James Halperin paints a picture that people can live 150 years or longer.3 of a future world in which people rou- aging tinely have themselves frozen cryogenically until the day when scientists have cured can- Science: Why We Age, mechanisms cer and solved degenerative disorders.

Introducing Bionanotechnology Into Undergraduate Biomedical Engineering
AC 2009-504: INTRODUCING BIONANOTECHNOLOGY INTO UNDERGRADUATE BIOMEDICAL ENGINEERING Aura Gimm, Duke University J. Aura Gimm is Assistant Professor of the Practice and Associated Director of Undergraduate Studies in the Department of Biomedical Engineering at Duke University. She teaches courses in biomaterials, thermodynamics/kinetics, engineering design, and a new course in bionanotechnology. Dr. Gimm received her S.B. in Chemical Engineering and Biology from MIT, and her Ph.D. in Bioengineering from UC-Berkeley. Page 14.802.1 Page © American Society for Engineering Education, 2009 Introducing Bionanotechnology in Undergraduate Biomedical Engineering Abstract As a part of the NSF-funded Nanotechnology Undergraduate Education Program, we have developed and implemented a new upper division elective course in Biomedical Engineering titled “Introduction to Bionanotechnology Engineering”. The pilot course included five hands- on “Nanolab” modules that guided students through specific aspects of nanomaterials and engineering design in addition to lecture topics such as scaling effects, quantum effects, electrical/optical properties at nanoscale, self-assembly, nanostructures, nanofabrication, biomotors, biological designing, biosensors, etc. Students also interacted with researchers currently working in the areas of nanomedicine, self-assembly, tribiology, and nanobiomaterials to learn first-hand the engineering and design challenges. The course culminated with research or design proposals and oral presentations that addressed specific engineering/design issues facing nanobiotechnology and/or nanomedicine. The assessment also included an exam (only first offering), laboratory write-ups, reading of research journal articles and analysis, and an essay on ethical/societal implications of nanotechnology, and summative questionnaire. The course exposed students to cross-disciplinary intersections that occur between biomedical engineering, materials science, chemistry, physics, and biology when working at the nanoscale. -

Cellular Senescence and the Senescent Secretory Phenotype: Therapeutic Opportunities
Cellular senescence and the senescent secretory phenotype: therapeutic opportunities Tamara Tchkonia, … , Judith Campisi, James L. Kirkland J Clin Invest. 2013;123(3):966-972. https://doi.org/10.1172/JCI64098. Review Series Aging is the largest risk factor for most chronic diseases, which account for the majority of morbidity and health care expenditures in developed nations. New findings suggest that aging is a modifiable risk factor, and it may be feasible to delay age-related diseases as a group by modulating fundamental aging mechanisms. One such mechanism is cellular senescence, which can cause chronic inflammation through the senescence-associated secretory phenotype (SASP). We review the mechanisms that induce senescence and the SASP, their associations with chronic disease and frailty, therapeutic opportunities based on targeting senescent cells and the SASP, and potential paths to developing clinical interventions.

Personalized Nanomedicine
Published OnlineFirst July 24, 2012; DOI: 10.1158/1078-0432.CCR-12-1414 Clinical Cancer Perspective Research Personalized Nanomedicine Twan Lammers1,2,3, Larissa Y. Rizzo1, Gert Storm2,3, and Fabian Kiessling1 Abstract Personalized medicine aims to individualize chemotherapeutic interventions on the basis of ex vivo and in vivo information on patient- and disease-specific characteristics. By noninvasively visualizing how well image-guided nanomedicines—that is, submicrometer-sized drug delivery systems containing both drugs and imaging agents within a single formulation, and designed to more specifically deliver drug molecules to pathologic sites—accumulate at the target site, patients likely to respond to nanomedicine-based therapeutic interventions may be preselected. In addition, by longitudinally monitoring how well patients respond to nanomedicine-based therapeutic interventions, drug doses and treatment protocols can be individualized and optimized during follow-up. Furthermore, noninvasive imaging information on the accumulation of nanomedicine formulations in potentially endangered healthy tissues may be used to exclude patients from further treatment. Consequently, combining noninvasive imaging with tumor-targeted drug delivery seems to hold significant potential for personalizing nanomedicine-based chemotherapeutic interventions, to achieve delivery of the right drug to the right location in the right patient at the right time.
