Water quantity and quality data were compared from six headwater watersheds on two distinct soil formations, Carolina Slate Belt (CSB) and Triassic Basins (TB). CSB soils are generally thicker, less erodible, and contain less clay content than soils found in TB. TB generated significantly more discharge ⁄precipitation ratio than CSB (0.33 vs. 0.24) in the 2009 dormant season. In the 2009 growin...

The CSB protein is a member of the SWI2/SNF2 family of ATP-dependent chromatin remodeling factors and is essential for transcription-coupled DNA repair. The role of CSB in this DNA repair process is unclear, but the protein was found to remodel nucleosomes and alter DNA double helix conformation upon binding. Elucidating the nature of the change in DNA structure induced by CSB is of great inter...

The phenotype of the human genetic disorder Cockayne syndrome (CS) is not only due to DNA repair defect but also (and perhaps essentially) to a severe transcription initiation defect. After UV irradiation, even undamaged genes are not transcribed in CSB cells. Indeed, neither RNA pol II nor the associated basal transcription factors are recruited to the promoters of the housekeeping genes, arou...

Surveys have long been a dominant instrument for data collection in public administration. However, it has become widely accepted in the last decade that the usage of a self-reported instrument to measure both the independent and dependent variables results in common source bias (CSB). In turn, CSB is argued to inflate correlations between variables, resulting in biased findings. Subsequently, ...

BACKGROUND Autonomic abnormalities exist in heart failure and contribute to disease progression. Activation of the carotid sinus baroreflex (CSB) has been shown to reduce sympathetic outflow and augment parasympathetic vagal tone. This study tested the hypothesis that long-term electric activation of the CSB improves left ventricular (LV) function and attenuates progressive LV remodeling in dog...

The DNA repair protein Cockayne syndrome group B (CSB) has been recently identified as a promising anticancer target. Suppression, by antisense technology, of this protein causes devastating effects on tumor cells viability, through a massive induction of apoptosis, while being non-toxic to non-transformed cells. To gain insights into the mechanisms underlying the pro-apoptotic effects observed...

In the present study we show that a number of cancer cell lines from different tissues display dramatically increased expression of the Cockayne Syndrome group B (CSB) protein, a DNA repair factor, that has recently been shown to be involved in cell robustness. Furthermore, we demonstrated that ablation of this protein by antisense technology causes devastating effects on tumor cells through a ...

The arterial baroreflex opposes pressor responses to muscle ischemia (muscle chemoreflex). Our experiments sought to quantify the unknown effects of muscle chemoreflex on carotid sinus baroreflex (CSB) sensitivity. We generated CSB stimulus-response (S-R) curves by pulsatile application (triggered by each electrocardiogram R wave) of positive and negative neck pressure (from 60 to -80 mmHg in 2...

Cockayne syndrome (CS) is a premature aging disorder characterized by photosensitivity, impaired development and multisystem progressive degeneration, and consists of two strict complementation groups, A and B. Using a yeast two-hybrid approach, we identified the 5'-3' exonuclease SNM1A as one of four strong interacting partners of CSB. This direct interaction was confirmed using purified recom...

OBJECTIVE To evaluate the association of a nationwide comprehensive smoking ban (CSB) and tobacco tax increase (TTI) on the risk of acute myocardial infarctions (AMI) in Panama for the period of 2006 - 2010 using hospital admissions data. METHODS Data of AMI cases was gathered from public and private hospitals in the country for the period of January 1, 2006 to December 31, 2010. The number o...
