Liver fat storage, also called hepatic steatosis, is increasingly common and represents a very frequent diagnosis in the medical field. Excess fat is not without consequences. In fact, hepatic steatosis contributes to the progression toward liver fibrosis. There are two main types of fatty liver di...
Significance: The re- sults of this study show that cocaine dependence is associated with a loss of psychostimulant-induced dopamine release in the striatum, with no change in D1 receptor availability in this brain region. It also puts these changes in neurochemistry into perspective by cor- ...
Upon apoptosis induction, BAX undergoes conformational change. This exposes its transmembrane domain, leading to the insertion of BAX into the outer mitochondrial membrane. BAX-BAK heterodimers form mitochondrial pores, which leads to the release of mitochondrial proteins into the cytoplasm, including ...
X-rays, CT scans, and MRIs may be indicated depending upon the patient's needs. How is vertigo diagnosed? The diagnosis of vertigo is most often made based upon history and clinical presentation. If the patient is experiencing a spinning sensation that worsens by a change in position and les...

It can be tough to identify them all, and they can change. For example, you might not have been bothered by tree pollen when you were a child, only to have a problem with it as an adult. Even when you know your triggers, you might have a hard time avoiding them in certain situati...
During CDI, toxin-mediated intestinal inflammation induces host immune responses that change metal availability (Figure 2). C. difficile produces two primary toxins, TcdA and TcdB, involved in intestinal inflammation and epithelial damage [26]. The host immune response to these toxins is in part ...
The physical foundation for the release of force when reflection takes place was recognized as long ago as 1687 by Isaac Newton, who stated that any change in momentum necessarily involves the action of force. Generally, the following holds (after Newton): ...
So, it is well established that spines emerge, disappear, and change with cellular events thought to underlie learning processes. But is this merely a correlation or are there ways towards showing that these events really lie at the basis of learning and memory storage in the brain? Recent ...
