SYNTHESIS AND IN VITRO ANTICANCER ACTIVITY OF 8-CHLORO-3-CYANO-4-IMINO-2-METHYLTHIO-4H-PYRIMIDO [2, 1-B] [1, 3] BENZOTHIAZOLE AND ITS 2-SUBSTITUTED DERIVATIVES

oai:ojs.www.jprhc.in:article/398-Chloro-3-cyano-4-imino-2-methylthio-4H-pyrimido [2, 1-b] [1, 3] benzothiazole and its 2-substituted derivatives has been prepared and evaluated at National Cancer Institute, Maryland, USA for their in vitro anticancer activity towards 60 Human Cancer cell lines, derived from various cancer types. Results revealed that all these compounds displayed remarkable anticancer action across human cancer cell lines. Compounds 3, 4c and 4e are selected by NCI for further anticancer activity at five dose concentration level

Clinical development of new drug-radiotherapy combinations.

In countries with the best cancer outcomes, approximately 60% of patients receive radiotherapy as part of their treatment, which is one of the most cost-effective cancer treatments. Notably, around 40% of cancer cures include the use of radiotherapy, either as a single modality or combined with other treatments. Radiotherapy can provide enormous benefit to patients with cancer. In the past decade, significant technical advances, such as image-guided radiotherapy, intensity-modulated radiotherapy, stereotactic radiotherapy, and proton therapy enable higher doses of radiotherapy to be delivered to the tumour with significantly lower doses to normal surrounding tissues. However, apart from the combination of traditional cytotoxic chemotherapy with radiotherapy, little progress has been made in identifying and defining optimal targeted therapy and radiotherapy combinations to improve the efficacy of cancer treatment. The National Cancer Research Institute Clinical and Translational Radiotherapy Research Working Group (CTRad) formed a Joint Working Group with representatives from academia, industry, patient groups and regulatory bodies to address this lack of progress and to publish recommendations for future clinical research. Herein, we highlight the Working Group's consensus recommendations to increase the number of novel drugs being successfully registered in combination with radiotherapy to improve clinical outcomes for patients with cancer.National Institute for Health ResearchThis is the final version of the article.

The development of mental health services within primary care in India: learning from oral history.

BACKGROUND: In India very few of those who need mental health care receive it, despite efforts of the 1982 National Mental Health Programme and its district-level component the District Mental Health Programme (DMHP) to improve mental health care coverage. AIMS: To explore and unpack the political, cultural and other historical reasons for the DMHP's failures and successes since 1947 (post-independence era), which may highlight issues for today's current primary mental health care policy and programme. METHODS: Oral history interviews and documentary sourcing were conducted in 2010-11 with policy makers, programme managers and observers who had been active in the creation of the NMHP and DMHP. RESULTS: The results suggest that the widely held perception that the DMHP has failed is not entirely justified, insofar that major hurdles to the implementation of the plan have impacted on mental health coverage in primary care, rather than faults with the plan itself. These hurdles have been political neglect, inadequate leadership at central, state and district levels, inaccessible funding and improperly implemented delivery of services (including poor training, motivation and retention of staff) at district and community levels. CONCLUSION: At this important juncture as the 12th Five Year Plan is in preparation, this historical paper suggests that though the model may be improved, the most important changes would be to encourage central and state governments to implement better technical support, access to funds and to rethink the programme leadership at national, state and district levels

The effective population size of malaria mosquitoes: large impact of vector control.

Malaria vectors in sub-Saharan Africa have proven themselves very difficult adversaries in the global struggle against malaria. Decades of anti-vector interventions have yielded mixed results--with successful reductions in transmission in some areas and limited impacts in others. These varying successes can be ascribed to a lack of universally effective vector control tools, as well as the development of insecticide resistance in mosquito populations. Understanding the impact of vector control on mosquito populations is crucial for planning new interventions and evaluating existing ones. However, estimates of population size changes in response to control efforts are often inaccurate because of limitations and biases in collection methods. Attempts to evaluate the impact of vector control on mosquito effective population size (N(e)) have produced inconclusive results thus far. Therefore, we obtained data for 13-15 microsatellite markers for more than 1,500 mosquitoes representing multiple time points for seven populations of three important vector species--Anopheles gambiae, An. melas, and An. moucheti--in Equatorial Guinea. These populations were exposed to indoor residual spraying or long-lasting insecticidal nets in recent years. For comparison, we also analyzed data from two populations that have no history of organized vector control. We used Approximate Bayesian Computation to reconstruct their demographic history, allowing us to evaluate the impact of these interventions on the effective population size. In six of the seven study populations, vector control had a dramatic impact on the effective population size, reducing N(e) between 55%-87%, the exception being a single An. melas population. In contrast, the two negative control populations did not experience a reduction in effective population size. This study is the first to conclusively link anti-vector intervention programs in Africa to sharply reduced effective population sizes of malaria vectors
