The purposes of this study were to evaluate the effect integrating cultural content (ICC) in an undergraduate nursing curriculum on students' self-perceived competence, and determine whether a 5-week clinical immersion international (ICC Plus) had any additional competence. Cultural competence was measured using 28-item scale regarding knowledge, self-awareness, comfort with skills Pretest scores from admission into program matched posttest obtained just prior graduation for 32 students, 7...

Surface neutrophil CD64 expression has been shown upregulated in cases infection. Recently, a standardized kit the index was used neonatal intensive care units, showing high sensitivity specificity infections.

Cellular resistance to methotrexate (MTX) is believed be unaffected by expression of MDRI P-glycoprotein (Pgp), a pleiotropic efflux pump acting on different hydrophobic compounds that enter cells passive diffusion. A series human leukemic CCRF-CEM sublines, isolated multi-step selection for very high MTX, exhibit multiple mechanisms MTX resistance, including decreased carrier-mediated uptake and DHFR gene amplification. These sublines show cross-resistance drugs the multi-drug (MDR) family,...

Students enrolled in online asynchronous courses do not typically experience the same social and emotional benefits as students who attend a campus classroom (Lin & Gao, 2020). Challenges include lack of peer interactions, networking opportunities, peer-to-peer support, general sense belonging to (Öztürk, 2021). Still, many post-pandemic remain reticent return on-campus classes (Horváth et al., 2022). Three faculty members at four-year university an undergraduate retailing program partnered...

The adherence of Candida albicans yeast cells to the subendothelial extracellular matrix, fibronectin, laminin, and type I IV collagen was tested. Fibronectin (10(-7) M) a peptide, PepTite-2000 (Telios Pharmaceuticals Inc., San Diego, Calif.), containing sequence arginine-glycine-aspartic acid (RGD) inhibited these targets by greater than 90%. When C. perfused over ex vivo rabbit aortic endothelium, there no significant difference in amount presence or absence RGD-containing peptide....

Abstract Time Management Skills and Student Performance in Online CoursesIt has been said that “A goal without a plan is just wish.” (Antoine de Saint-Exupéry). Aseducators, we have the almost daily task of turning wishes come with education into therealities degrees careers. In part, accomplish this by requiring students to - isto use their time effectively course goals objectives.Previous research authors revealed had learn manage orderto be successful. Furthermore, many indicated...

We have previously described a series of methotrexate (MTX)-selected CCRF-CEM sublines (CEM/MTX R1–3) displaying increased resistance to drugs associated with the multidrug phenotype and provided evidence that MDR1 P-glycoprotein contributes multifactorial MTX in these cells. also suggested P-glycoprotein-mediated transport arises cells due deficiency normal route, reduced folate carrier (RFC). now determined nucleotide sequence RFC gene CEM/MTX R1–3 confirm is defective as result premature...
