objective: an important factor in the prevention of industrial accidents is the employees’ ability to maintain their awareness of the work situation, understand the information it holds, and predict the development of the situations. in this study, we examined the role of work stress and sleepiness in predicting work situation awareness among workers. methods: the present study was a cross-sec...
Introduction Fanleaf degeneration/decline disease is one of the most severe viral disease complexes of grapevine worldwide. It is also one of the oldest known viral diseases of Vitis vinifera with descriptions of symptoms being reported in Europe as early as 1841. This disease is now known to affect grapevines in all temperate regions where Vitis vinifera and hybrid rootstocks are grown. Within...
The lack of DNA sequence information for most non-model organisms impairs the design of primers that are universally applicable for the study of molecular polymorphisms in nuclear markers. Next-generation sequencing (NGS) techniques nowadays provide a powerful approach to overcome this limitation. We present a flexible and inexpensive method to identify large numbers of nuclear primer pairs tha...
DNA variation in a 4.7-kb region of the cytosolic phosphoglucose isomerase (PgiC) locus was investigated for 21 ecotypes of Arabidopsis thaliana. The estimated nucleotide diversity was 0.0038, which was one-third of those in previously investigated loci. Since most of the nucleotide variations (93%) were singleton and doubleton, Tajima's test statistic was significantly negative. About 50% of n...
abdominal wall hernia is common but reliable scientific data about its work relatedness is very limited and inconsistent. in this paper, a less common type of abdominal wall hernia in a 30 year old male worker is presented with recurrence after first surgery when he returned to work. in contrast with almost all kinds of hernia, a lifelong limitation for heavy lifting was recommended. it seems t...
To investigate DNA variation in natural plant populations, a 1.8-kb region of the acidic chitinase locus (ChiA)was analyzed for 17 ecotypes of Arabidopsis thaliana sampled worldwide and 3 Arabis species in Japan. As in the Adh region, dimorphism was detected throughout the investigated ChiA region, suggesting the possibility that dimorphic DNA variation exists in the entire nuclear genome of A....
Many pathogen recognition genes, such as plant R-genes, undergo rapid adaptive evolution, providing evidence that these genes play a critical role in plant-pathogen coevolution. Surprisingly, whether rapid adaptive evolution also occurs in genes encoding other kinds of plant defense proteins is unknown. Unlike recognition proteins, plant chitinases attack pathogens directly, conferring disease ...
