The present industry update covers the period 1-31 December 2014, with information sourced from company press releases, regulatory and patent agencies as well as the scientific literature. December is traditionally the month of last year-closure announcements or starting looking back into the recent past. The financing community for biotech seems on strong recovery as indicated by reports, but also in view of many deals discussed in these proceedings. The teaming up of a company owning a (novel) active ingredient and another one having a drug-delivery device addressing certain limitations proves to be a recipe for success (Asante, Unilife, Catalent and Endo Pharmaceuticals)...

A thin section culture system for rapid regeneration of the monopodial orchid hybrid Aranda Deborah has been developed. Thin sections (0.6-0.7mm thick) obtained by transverse sectioning of a single shoot tip (6-7mm), when cultured in Vacin and Went medium enriched with coconut water (20% v/v), produced an average 13.6 protocorm-like bodies (PLB) after 45 days, compared to 2.7 PLB formed by a single 6-7 mm long shoot tip under same culture condition. Addition of α-naphthaleneacetic acid to Vacin and Went medium enriched with coconut water further increased PLB production by thin sections...

Coelogyne nervosa is an epiphytic orchid endemic to Western Ghats, South India. The mature seeds of C. nervosa were cultured on ½ MS (Murashige and Skoog), MS, Kn (Knudson) and VW (Vacin and Went) media to evaluate the seed germination response. Of the four basal media used, MS medium supported maximum seed germination. Further experiments to enhance seed germination were done on MS medium supplemented with various concentrations (10, 20, 30 and 40 %) of coconut water (CW). Thirty percent CW gave the highest response in terms of percent seed germination (96), fresh weight (7...

Vaccination coverage in the so-called "developing countries" is still lower than expected. Such coverage is an important indicator of population health and the quality of care provided by the health care system. The current study describes the results of a household survey to estimate coverage of the basic immunization schedule in the first year of life in State capitals in Northeast Brazil, for the 2005 birth cohort. The methodology used was that recommended by the Pan American Health Organization for surveys on vaccination coverage...

BACKGROUND AND AIMS: Cymbidium mastersii is an epiphytic orchid distributed mainly in Northeast India. Owing to its high commercial value in the floricultural industry, natural populations are under threat from over-exploitation. Mass propagation provides an alternative means of satisfying the demand. Unfortunately, conventional propagation is slow and difficult, suggesting in vitro methods for mass multiplication may be more appropriate. The objective of this study was to develop an efficient protocol...

Substance use disorders continue to be major medical and social problems worldwide. Current medications for substance use disorders have many limitations such as cost, availability, medication compliance, dependence, diversion of some to illicit use and relapse to addiction after discontinuing their use. Immunotherapies using either passive monoclonal antibodies or active vaccines have distinctly different mechanisms and therapeutic utility from small molecule approaches to treatment. They have great potential to help the patient achieve and sustain abstinence and have fewer of the above limitations...

Chagas disease is major public health problem, affecting nearly 10 million people, characterized by cardiac alterations leading to congestive heart failure and death of 20-40% of the patients infected with Trypanosoma cruzi, the protozoan parasite responsible for the disease. A vaccine would be key to improve disease control and we review here the recent advances and challenges of a T. cruzi vaccine. There is a growing consensus that a protective immune response requires the activation of a Th1 immune profile, with the stimulation of CD8 (+) T cells...

BACKGROUND: Hepatitis B virus (HBV) is the major cause of chronic hepatitis,cirrhosis, and hepatocellular carcinoma. The global epidemiological scenario of HBV infection has been changing rapidly over the last two decades due to an effective immunization programme initiated by the World Health Organization. The objective of this study is to estimate the prevalence of HBV in apparently adult people who were taken health examination in our Hospital. METHODS: A cross-sectional seroprevalence analysis of hepatitis B virus infection was performed in 12037 adult residents (aged > or =18 years) in Chengdu, who visited Health Examination Center of West China Hospital of Sichuan University for routine medical check-up during the period from March to December 2008...

The pathogenesis of Alzheimer's disease (AD) has been strongly associated with the accumulation of amyloid beta (Aβ) peptides in brain, and immunotherapy targeting Aβ provides potential for AD prevention. A clinical trial in which AD patients were immunized with Aβ42 peptide was stopped when 6% of participants showed meningoencephalitis, apparently due to an inflammatory Th1 immune response. Previously, we and other have shown that Aβ42 DNA vaccination via gene gun generates a Th2 cellular immune response, which was shown by analyses of the respective antibody isotype profiles...

Meningococcal disease remains a global public health concern despite the wide availability of polysaccharide and polysaccharide-protein conjugate vaccines. The latter often afford a greater duration and scope of protection compared with the former. A novel quadrivalent meningococcal conjugate vaccine, Menveo(®) (MenACWY-CRM; Novartis Vacines, Bellaria-Rosia, Italy) has recently been licensed in Europe, the USA, Canada and other countries to protect adolescents and adults against disease caused by serogroups A, C, W-135 and Y...

To examine the effectiveness of super-elevated (10,000 micromol mol(-1)) CO(2) enrichment under cold cathode fluorescent lamps (CCFL) for the clonal propagation of Cymbidium, plantlets were cultured on modified Vacin and Went (VW) medium under 0, 3,000 and 10,000 micromol mol(-1) CO(2) enrichment and two levels of photosynthetic photon flux density (PPFD, 45 and 75 micromol m(-2) s(-1)). Under high PPFD, 10,000 micromol mol(-1) CO(2) increased root dry weight and promoted shoot growth. In addition, a decrease in photosynthetic capacity and chlorosis at leaf tips were observed...

BACKGROUND AND AIMS: Ecotypic differentiation has been explored in numerous plant species, but has been largely ignored in the Orchidaceae. Applying a specific germination protocol for widespread seed sources may be unreliable due to inherent physiological or genetic differences in localized populations. It is crucial to determine whether ecotypic differentiation exists for restoration and conservation programmes. Calopogon tuberosus var. tuberosus, a widespread terrestrial orchid of eastern North America, is a model species to explore ecotypic differences in germination requirements, as this species occupies diverse habitats spanning a wide geographical range...

Protocorms of Vanda coerulea were successfully cryopreserved by encapsulation-dehydration in combination with a loading solution. Protocorms were selected 70 days after sowing seeds harvested from 7-month-old fruits. After encapsulation in an alginate matrix composed of 2 percent Na-alginate, 2 M glycerol plus 0.4 M sucrose (loading solution), the protocorms were precultured in modified Vacin and Went (1949) (VW) liquid medium supplemented with 0.7 M sucrose on a shaker (110 rpm) at 25 +/- 3 degree C for 20 h...

Levamisole (2, 3, 5, 6-tetrahydro-6-phenylimidazole 2,1-b thiazole) is a well-known nonspecific stimulator of host defence mechanisms. In previous investigations, we have found that levamisole acts on cell-mediated immunity in challenge-induced porcine postweaning colibacillosis (PWC). We assume that levamisole could also act synergistically on humoural immune response when applied as an adjuvant with vaccine candidate strains for oral immunization of weaned pigs against PWC. The influence of levamisole in combination with experimental F4ac(+) nonenterotoxigenic Escherichia coli (non-ETEC) vacinal strain on proliferation of IgA(+) cells was examined in 4-week-old weaned pigs experimentally infected with ETEC...
