Enzyme mechanisms are the chemical transformations, and the steps within them, generated by enzymatic action on substrates. The mechanism of enzyme catalysis is similar in principle to other types ...

Lissencephaly is a severe neurodevelopmental disease often caused by mutations in the Dcx gene. Using a human cellular model of lissencephaly, the authors report that DCX restricts neuronal ...

Figure 1 Mechanisms of pathogen avoidance. A variety of comprehensive mechanisms are in place to regulate pathogens avoidance, which include those caused by the alteration of aerotaxis, intestinal ...

In the expression of interest, the DRDO stated that during the design and development of the weapons system (barrel, breech mechanism, muzzle brake and recoil system), the Armament Research and ...

This article will review the mechanisms of activation of alternative, classical, and lectin pathways, the formation of C3 and C5 convertases, the action of anaphylatoxins, and the ...

Crohn's disease and ulcerative colitis are idiopathic, chronic, relapsing, inflammatory conditions that are immunologically mediated. Although their exact etiologies remain uncertain, results from ...

In this Review, we summarise common mechanisms driving acute and long-term side-effects and discuss monitoring strategies for radiotherapy survivors. We explore ways to mitigate toxic effects through ...
