Many classes of DNA-damaging agents are known to induce oxidative stress, which is a major cause for dysfunction of cellular organelles and cell death.
Because most patients with abnormal pupils were not in cardiac arrest, pupil dysfunction implies that other causes for brainstem dysfunction were present.
There are many causes for the dysfunction: strident partisanship, unyielding ideology, a corrosive system of campaign financing, gerrymandering of House districts, endless filibusters, holds on executive appointees in the Senate, dwindling social interaction between senators of opposing parties and a caucus system that promotes party unity at the expense of bipartisan consensus.
All participants of the control group had to complete the same questionnaires and received an ENT examination in order to exclude the same causes for olfactory dysfunction as for the MS patients.
Diseases, resection or bypass surgeries of ileum, dietary factors causing impaired ileal function (high carbohydrate and cholesterol) and alcoholism are the main causes for ileal dysfunction [ 8].
An algorithm was established combining and transforming the gene-expression signals into a continuous, nondimensional score indicating either infectious or noninfectious causes for organ dysfunction.
It is difficult to identify the leading causal relationship theory for the symptoms in question; in difficult cases of functional disorders accompanied by auriculovestibular symptoms, numerous possible causes for the dysfunction of the middle and the inner ear as well as the functional disorders of the masticatory organ should be taken into account [ 22, 24].
In the following sections, we will review our current understanding of cellular senescence induced by a variety of stimuli and stresses that affect telomere length and structure, as well as summarize studies that shed light into the likely causes for telomere dysfunction and cellular senescence in cells of inactive and benign human tumors.
The actual mfERG tracings and hexagon analysis for these two carriers are shown in Figs. 2 and 3. Our findings support the conclusion that the presence of a functional abnormality on mfERG testing, in the absence of other causes for retinal dysfunction in a female at risk, should suggest the presence of a carrier state for XLRS, which could then be further confirmed by genetic testing.
A multifaceted approach is needed to address the basic causes of dysfunction in the market for public health commodities.
