Cerebral or meningeal vasodilation and potential perivascular release of vasoactive substances may lead to headache generation in migraine [4].
(C) Abuse of the drug or other substances may lead to severe psychological or physical dependence.
Reductive substances may lead to chemical modifications of the toxic inhibitor compounds, thereby changing the degree of toxicity [ 15].
Study results show that nasal decolonization with Mupirocin, in combination with other substances, may lead to a reduction of MRSA infections.
At such temperatures, enzymatic activity (by cartilage-degrading cytokines such as IL-1 and IL-6, metalloproteinases, and other substances), may lead to cartilage damage.
It has become clear that there are unique developmental stages of susceptibility between species and embryonic exposure to harmful substances may lead to impairment of cardiac development and function [ 13, 29– 329.
The production or release of these substances may lead to osmotic adjustment [ 20, 36], and help maintain integrity of cellular enzymes, proteins, nucleic acids and membranes [ 37], or protect against reactive oxygen species (ROS) [ 38, 39].
As these samples were collected from the ground in a relatively dry and warm environment, any DNA in the samples may have been degraded (e.g. Olson et al., 2005), and the presence of PCR inhibitory substances may lead to false negatives (e.g. Mathis and Deplazes, 2006).
The relationships among IPV and substance use are complex with some studies reporting increased substance use following IPV (29– 31), whereas others report that substance use may lead to higher rates of IPV (29, 32).
For instance, substance abuse may lead to high-risk behavior, which can lead to victimization and subsequently PTSD.
Alternatively, substance use may lead to risky situations wherein sex work was initiated (Sausa et al. 2007).
