Anxiety and depression symptoms, and lack of emotional support among the general population before and during the COVID-19 pandemic. A prospective national study on prevalence and risk factors.

Background: The effects of the COVID-19 pandemic on the mental health and emotional support among the general population are unclear. We therefore assessed if the prevalence of high Anxiety and Depression Symptoms (ADS) levels and lack of Emotional Support (ES) increased, and if risk factors of ADS and ES changed.

Methods: Data was extracted from surveys conducted with the Dutch longitudinal population-based LISS panel (N = 3,983).

MeioSeed: a CellProfiler-based program to count fluorescent seeds for crossover frequency analysis in .

Background: The formation of crossovers during meiosis is pivotal for the redistribution of traits among the progeny of sexually reproducing organisms. In plants the molecular mechanisms underlying the formation of crossovers have been well established, but relatively little is known about the factors that determine the exact location and the frequency of crossover events in the genome. In the model plant species , research on these factors has been greatly facilitated by reporter lines containing linked fluorescence marker genes under control of promoters active in seeds or pollen, allowing for the visualization of crossover events by fluorescence microscopy.

Mental health problems among search and rescue workers deployed in the Haïti earthquake 2010: a pre-post comparison.

Search and rescue workers play an important role in rescuing trapped disaster victims. However, it is unclear whether they are at risk for post-disaster mental health problems. For this purpose we prospectively examined pre- and post-deployment health among Dutch search and rescue workers (USAR NL) deployed in the devastating Haiti earthquake disaster (2010).

Vitamin B12 status in patients of Turkish and Dutch descent with depression: a comparative cross-sectional study.

Background: Studies have shown a clear relationship between depressive disorders and vitamin B12 deficiency. Gastroenteritis and Helicobacter pylori infections can cause vitamin B12 deficiency. Helicobacter pylori infections are not uncommon among people of Turkish descent in The Netherlands.
