Clicker Assessment and Feedback (CAF) is an instructional assessment and feedback strategy that is incorporated with interactive technologies, often referred to as clickers. Several thousand colleges and universities across Europe and North America have adopted CAF as a strategy in their classrooms. This study has three major objectives. The first objective is to discuss the development of an i...

CONTEXT Carbohydrate (CHO) and caffeine (CAF) both improve endurance performance. PURPOSE To determine by systematic literature review coupled with meta-analysis whether CAF ingested with CHO (CHO+CAF) improves endurance performance more than CHO alone. METHODS Databases were searched using the keywords caffeine, endurance, exercise, carbohydrate, and performance. Criteria for inclusion wer...

Caffeine (Caf) ingestion increases plasma epinephrine (Epi) and exercise endurance; these results are frequently transferred to coffee (Cof) consumption. We examined the impact of ingestion of the same dose of Caf in Cof or in water. Nine healthy, fit, young adults performed five trials after ingesting (double blind) either a capsule (Caf or placebo) with water or Cof (decaffeinated Cof, decaff...

background: coronally advanced fl ap (caf) has been shown to effectively treat gingival recession. platelet rich plasma (prp), containing autologous growth factors, has been shown to promote soft tissue healing. the aim of this clinical study was to determine whether the addition of an autologous prp to a caf when compared to a caf alone would improve the clinical outcome for treatment of multi...

Caffeine (CAF) is one of the most widely and regularly consumed biologically active substances. We use computer simulation approach to the study of CAF activity by searching for its possible complexes with biopolymer fragments. The principal CAF target at physiologically important concentrations refers to adenosine receptors. It is a common opinion that CAF is a competitive antagonist of adenos...

The P/CAF protein has intrinsic histone acetyltransferase (HAT) activity and is capable of binding the transcriptional co-activator CBP. Here we show that P/CAF can regulate transcription and that this function is independent of its binding to CBP. The HAT domain of P/CAF has transcriptional activation potential in yeast. In mammalian cells P/CAF can stimulate transcription of the RSV promoter,...

Heterogeneity of carcinoma-associated fibroblasts (CAF) has long been recognized, but the functional significance remains poorly understood. Here, we report the distinction of two CAF subtypes in oral squamous cell carcinoma (OSCC) that have differential tumor-promoting capability, one with a transcriptome and secretome closer to normal fibroblasts (CAF-N) and the other with a more divergent ex...

Chromatin assembly factor CAF-1 facilitates the formation of nucleosomes on newly replicated DNA in vitro. However, the role of CAF-1 in development is poorly understood because mutants are not available in most multicellular model organisms. Biochemical evidence suggests that FASCIATA1, FASCIATA2 and MSI1 form CAF-1 in Arabidopsis thaliana. Because fasciata mutants are viable, CAF-1 is not ess...

BACKGROUND Cancer-associated fibroblasts (CAF) are activated fibroblasts in the cancer stroma and play an important role in cancer progression. Some reports have indicated the correlation between the expression of CAF markers and adverse prognosis in several cancers. However, no reports have studied CAF phenotype and its clinical relevance in esophageal squamous cell carcinoma (ESCC). METHODS...
