Industry perceptions of barriers to commercialization of regenerative medicine products in the UK.

AIMS: Regenerative medicine is an emerging field with the potential to provide widespread improvement in healthcare and patient wellbeing via the delivery of therapies that can restore, regenerate or repair damaged tissue. As an industry, it could significantly contribute to economic growth if products are successfully commercialized. However, to date, relatively few products have reached the market owing to a variety of barriers, including a lack of funding and regulatory hurdles. The present study analyzes industry perceptions of the barriers to commercialization that currently impede the success of the regenerative medicine industry in the UK. MATERIALS & METHODS: The analysis is based on 20 interviews with leading industrialists in the field. RESULTS: The study revealed that scientific research in regenerative medicine is thriving in the UK. Unfortunately, lack of access to capital, regulatory hurdles, lack of clinical evidence leading to problems with reimbursement, as well as the culture of the NHS do not provide a good environment for the commercialization of regenerative medicine products. CONCLUSION: Policy interventions, including increased translational government funding, a change in NHS and NICE organization and policies, and regulatory clarity, would likely improve the general outcomes for the regenerative medicine industry in the UK.

A Ritalina no Brasil: uma década de produção, divulgação e consumo

A Ritalina, nome comercial do metilfenidato, tem sido cada vez mais produzida e consumida no Brasil. Somente entre 2002 e 2006, produção brasileira de metilfenidato, cresceu 465%. Sua vinculação ao diagnóstico de TDAH tem sido fator predominante de justificativa para tal crescimento. Entretanto, os discursos que circulam em torno do tema e legitimam seu uso também contribuem para o avanço nas vendas. Estes discursos não estão despojados de atravessamentos sociais e são o objeto de estudo desta pesquisa. Este trabalho tem por objetivo fazer uma análise das publicações brasileiras sobre os usos da Ritalina, de 1998, ano em que o medicamento foi autorizado no Brasil, até 2008. Para tanto, realizamos uma busca em todos os periódicos de psiquiatria brasileiros indexados na base Scielo, assim como nos jornais e revistas direcionados para o público em geral com maior tiragem. Em nossa análise, discutimos quais pontos são priorizados e quais são omitidos nos discursos sobre o metilfenidato no Brasil, e quais são seus possíveis efeitos na prática clínica com o paciente. Além disso, as diferenças nas prioridades de informações encontradas nos dois tipos de publicação, leiga e científica, também são discutidas neste trabalho.

Folk medicine and horticulture

The article discusses the uses of marine organisms in folk medicine and in horticulture in the Philippines. Commonly used marine organisms are the different varieties of seaweeds, sea urchin, sea cucumber, turtle, crocodile and fishes such as grouper and rabbitfish.

The production of radionuclides for nuclear medicine from a compact, low-energy accelerator system.

The field of nuclear medicine is reliant on radionuclides for medical imaging procedures and radioimmunotherapy (RIT). The recent shut-downs of key radionuclide producers have highlighted the fragility of the current radionuclide supply network, however. To ensure that nuclear medicine can continue to grow, adding new diagnostic and therapy options to healthcare, novel and reliable production methods are required. Siemens are developing a low-energy, high-current - up to 10MeV and 1mA respectively - accelerator. The capability of this low-cost, compact system for radionuclide production, for use in nuclear medicine procedures, has been considered.

Quality analysis of herbal medicine products prepared from Herba sarcandrae by capillary electrophoresis with electrochemical detection

A capillary electrophoresis with electrochemical detection(CE-ED) method was developed for the quality analysis of herbal medicine products prepared from the same herb of Herba Sarcandrae: Fufang Caoshanhu tablets, Qingrexiaoyanning capsules, and Xuekang oral liquids. Under the optimal analysis conditions, the low detection limit[1.0x10(-7) mol/L(S/N=3)] and the wide linear range(1.0x10(-7)-1.0x10(-4) mol/L) were obtained for quality standard compound of isofraxidin. The precisions of the peak current and the migration time(as RSDs) for the real sample analysis were 2.0%-2.6%, and 1.2%-1.8% for isofraxidin, respectively.

The use of CE-electrochemiluminescence with ionic liquid for the determination of bioactive constituents in Chinese traditional medicine

CE/tris(2,2-bipyridyl) ruthenium(ll) (Ru(bpy)(3)(2+)) electrochemiluminescence (ECL), CEECL, with an ionic liquid (IL) detection system was established for the determination of bioactive constituents in Chinese traditional medicine opium poppy which contain large amounts of coexistent substances. A minimal sample pretreatment which involves a one-step extraction approach avoids both sample loss and environmental pollution. As the nearby hydroxyl groups in some alkaloid such as morphine may react with borate to form complexes and IL, as a high-conductivity additive in running buffer, could cause an enhanced field-amplified effect of electrokinetic injection. Running buffer containing 25 mM borax-8 mM 1-ethyl-3-methylimidazolium tetrafluoroborate (EMImBF(4)) IL (pH 9.18) was used which resulted in significant changes in separation selectivity and obvious enhancement in ECL intensities for those alkaloids with similar structures. Sensitive detection could be achieved when the distance between the Pt working electrode and the outlet of separation capillary was set at 150 mu m and the stainless steel cannula was fixed approximately 1 cm away from the outlet of the capillary. Quantitative analysis of four alkaloids was achieved at a detection voltage of 1.2 V and a separation voltage of 15 kV in less than 7 min.
