At first glance, cancer and ageing would seem to be unlikely bedfellows. Yet the origins for this improbable union can actually be traced back to a sequence of tragic— and some say unethical—events that unfolded more than half a century ago. Here we review the series of key observations that has led to a complex but growing convergence between our understanding of the biology of ageing and the ...
According to accepted principles of criminal law, whether in written Civil Law system or common law System, the mere existence of material and mental elements of a crime is not suffice, but their coincidence is also required. Only when they coincide in time, it may be said that the crime has occurred and criminal responsibility is completed. Many discussions have been put-forward in legal writi...
a review on application of nanotechnology for early breast cancer detection based on medical imaging
breast cancer is characterized by a distinct metastatic pattern involving the regional lymph nodes, bone marrow, lung and liver. tumour cell migration and metastasis share many similarities with leukocyte trafficking, which is critically regulated by chemokines and their receptors. detection of breast cancer and its metastasis at the earliest stage is important for the management and prediction...
Background and Objectives: Drug nanocarriers have usually optimized features which facilitate cellular uptake and increase drug efficacy, prevent drug degradation against enzymatic factors and decrease drug complications by targeted drug delivery to cancer cell. This study aimed to determine the anti-cancer nature of the synthesized magnetic Chitosan-hydroxyurea nanodrug on HeLa cell line, cerv...
