Although many studies have supported P. M. Fitts’s (1954) law as a description of the speed–accuracy trade-off for speeded movements, there has been a lack of research regarding movement duration for target-directed movements made at any other pace. In the present study, the duration of movements made at a naturally selected comfortable pace and a quick pace differed from Fitts’s law in a way t...

Much of the existing conceptualization of fluid flow in karst aquifers is based on work in extensively cemented and recrystallized Paleozoic and Mesozoic carbonates. Within these aquifers, flow is often primarily through conduits (White 1969, 1977; Smart and Hobbs 1986; Ford and Williams 1989), although diffuse flow may occur through secondary porosity, such as fractures and joints (Shuster and...

SIGNIFICANCE Shortly after the discovery of the role of hydrogen sulfide (H2S) in many physiological and pathological processes, attempts were made to develop novel pharmaceuticals that may be of benefit for treatment or prevention of a wide range of disorders. The promise of H2S-based therapeutics is now being demonstrated in clinical trials. Recent Advances: H2S-releasing drugs, such as SG100...

17 Helicobacter pylori VacA is a secreted pore-forming toxin that is comprised of two 18 domains, designated p33 and p55. The p55 domain has an important role in binding of VacA to 19 the cell surface. About 111 residues at the amino-terminus of p55 (residues 312-422) are 20 essential for the intracellular activity of VacA, which suggests that this region may constitute a 21 subdomain with an a...

PICT-1 was originally identified as a tumor suppressor. Here, we found that PICT-1 overexpression triggered pro-death autophagy without nucleolar disruption or p53 accumulation in U251 and MCF7 cells. Truncated PICT-1 fragments 181-346 and 1-346, which partly or totally lack nucleolar localization, showed weaker autophagy-inducing effects than full-length PICT-1 and a well-defined nucleolar mut...

With increase of multi-drug resistant Escherichia coli in community-acquired urinary tract infections (CA-UTI), other treatment option with a therapeutic efficacy and a low antibiotic selective pressure is necessary. In this study, we evaluated in vitro susceptibility of E. coli isolates from CA-UTI to fosfomycin (FM), nitrofurantoin (NI), temocillin (TMO) as well as trimethoprim-sulfamethoxazo...

TNF-α is a major cytokine implicated in rheumatoid arthritis. Its expression is regulated both at the transcriptional and posttranscriptional levels and recent data demonstrated that miRNAs are implicated in TNF-α response in macrophages. LPS-activated FLS isolated from RA patients express TNF-α mRNA but not the mature protein. This prompted us to look for miRNAs which could be implicated in th...
