Cancer metabolism has received renewed interest as a potential target for cancer therapy . In this study , we use a multi-scale modeling approach to interrogate the implications of three metabolic scenarios of potential clinical relevance: the Warburg effect , the reverse Warburg effect and glutamine addiction . At the... | Cancer metabolism is an emerging hallmark of cancer . In the past decade , a renewed focus on cancer metabolism has led to several distinct hypotheses describing the role of metabolism in cancer . To complement experimental efforts in this field , a scale-bridging computational framework is needed to allow rapid evalua... | [

There are a number of vaccine candidates under development against a small number of the most common outbreak filoviruses all employing the virus glycoprotein ( GP ) as the vaccine immunogen . However , antibodies induced by such GP vaccines are typically autologous and limited to the other members of the same species ... | Development of an effective vaccine against filovirus outbreaks is an important public health aim .

We reasoned that as FcγR-expressing cells a... | Dengue has become a major international public health concern in recent decades . There are four dengue virus serotypes . Recovery from infection with one serotype confers life-long protection to the homologous serotype but only partial protection to subsequent infection with other serotypes .
