A mutational spectrum analysis in the ruvA strain demonstrated a general depression of mutagenesis at all sites of both umuC-dependent and umuC-independent gamma-radiation mutagenesis, which is in marked contrast with the site-specific reduction in gamma-radiation mutagenesis that is observed in the umuC mutant.
However, even among those who demonstrated a full depression response, nearly three-quarters continued to have either moderate or severe fatigue at 6 and 12 months.
Sekizawa and coworkers demonstrated a marked depression of the cough reflex in elderly patients with aspiration pneumonia [ 1].
However, female mice exposed for 90 days to chloral hydrate in the drinking water demonstrated a significant depression in humoral immune function.
Although several studies have demonstrated a relationship between depression and utilization of health care in ESRD and other chronic illnesses in developing countries, such evidence from hemodialysis patients is lacking in Iran.
In a review of literature, A. Byrne and D.G. Byrne [ 18] indicated that 90% of studies demonstrated a decrease in depression and anxiety after participation in physical activity interventions.
A recent study demonstrated a relationship between depression and violent crime [ 6], while some studies argue that this association is better explained by co-morbid substance abuse [ 5, 7] and is stronger for bipolar disorder [ 8– 10].
Additionally, the fact that we demonstrated a gradient of depression moving from metropolitan cities to micropolitan cities and to small town/rural areas further supports the idea that living in rural areas is an important risk factor for depression in patients with HIV.
Caregivers also demonstrated a moderate degree of depression (mean WebNeuro depression score: 5.05 ± 2.10), anxiety (mean WebNeuro anxiety score: 5.12 ± 2.49), stress (mean WebNeuro stress score: 4.27 ± 1.78), and low quality of life (mean AQoL-8D utility score: 0.66 ± 0.18).
Weight and depression demonstrated a U-shaped relationship, with higher prevalence of depression observed among underweight and obese general practice patients.
