The Effects of Emergency Room Violence toward Nurse's Intention to Leave-Resilience as a Mediator.

(1) Background: Healthcare workplace violence has been a focused issue in the whole world. The rate of the occurrence is pretty high in every country. The emergency room is a high risk and high frequency place for violence to occur.

Discovery of a Novel Anti-Cancer Agent Targeting Both Topoisomerase I & II as Well as Telomerase Activities in Human Lung Adenocarcinoma A549 Cells In Vitro and In Vivo: Cinnamomum verum Component Cuminaldehyde.

Cinnamomum verum is used to make the spice cinnamon and has been used for more than 5000 years by both of the two most ancient forms of medicine in the words: Ayurveda and traditional Chinese herbal medicines for various applications such as adenopathy, rheumatism, dermatosis, dyspepsia, stroke, tumors, elephantiasis, trichomonas, yeast, and virus infections. We evaluated the anticancer effect of cuminaldehyde (CuA), a constituent of the bark of the plant, and its underlying molecular biomarkers associated with carcinogenesis in human lung adenocarcinoma A549 cells. The results show that cuminaldehyde suppressed proliferation and induced apoptosis as indicated by mitochondrial membrane potential loss, activation of caspase 3 and 9, increase in annexin V+PI+ cells, and morphological characteristics of apoptosis, including blebbing of plasma membrane, nuclear condensation, fragmentation, apoptotic body formation, and comet with elevated tail intensity and moment.

Cinnamomum verum component 2-methoxycinnamaldehyde: a novel antiproliferative drug inducing cell death through targeting both topoisomerase I and II in human colorectal adenocarcinoma COLO 205 cells.

Background: Cinnamomum verum is used to manufacture the spice cinnamon. In addition, the plant has been used as a Chinese herbal medication.

Methods: We investigated the antiproliferative effect of 2-methoxycinnamaldehyde (2-MCA), a constituent of the cortex of the plant, and the molecular biomarkers associated with tumorigenesis in human colorectal adenocarcinoma COLO 205 cells.

Cuminaldehyde from Cinnamomum verum Induces Cell Death through Targeting Topoisomerase 1 and 2 in Human Colorectal Adenocarcinoma COLO 205 Cells.

Cinnamomum verum, also called true cinnamon tree, is employed to make the seasoning cinnamon. Furthermore, the plant has been used as a traditional Chinese herbal medication. We explored the anticancer effect of cuminaldehyde, an ingredient of the cortex of the plant, as well as the molecular biomarkers associated with carcinogenesis in human colorectal adenocarcinoma COLO 205 cells.

Cinnamomum verum ingredient 2-methoxycinnamaldehyde: a new antiproliferative drug targeting topoisomerase I and II in human lung squamous cell carcinoma NCI-H520 cells.

Cinnamomum verum has been used as a Chinese herbal medication. We investigated the antiproliferative effect of 2-methoxycinnamaldehyde (2-MCA), a constituent of the cortex of the plant, and the molecular biomarkers associated with tumorigenesis in human lung squamous cell carcinoma NCI-H520 cells. The effects of 2-MCA on cell growth, cytotoxicity, apoptosis, and topoisomerase I and II activities in human lung squamous cell carcinoma NCI-H520 cells were evaluated in vitro and in vivo.

Cinnamomum verum Component 2-Methoxycinnamaldehyde: A Novel Anticancer Agent with Both Anti-Topoisomerase I and II Activities in Human Lung Adenocarcinoma A549 Cells In Vitro and In Vivo.

Cinnamomum verum is used to make the spice cinnamon and has been used as a traditional Chinese herbal medicine. We evaluated the anticancer effect of 2-methoxycinnamaldehyde (2-MCA), a constituent of the bark of the plant, and its underlying molecular biomarkers associated with carcinogenesis in human lung adenocarcinoma A549 cells. The results show that 2-MCA suppressed proliferation and induced apoptosis as indicated by an upregulation of pro-apoptotic Bax and Bak genes and downregulation of anti-apoptotic Bcl-2 and Bcl-XL genes, mitochondrial membrane potential loss, cytochrome c release, activation of caspase-3 and -9, and morphological characteristics of apoptosis, including plasma membrane blebbing and long comet tail.

Lateral trap-door window approach with maxillary sinus membrane lifting for dental implant placement in atrophied edentulous alveolar ridge.

One of the most challenging and technically sensitive surgical procedures in conjunction with dental implant rehabilitation is sinus membrane lifting to increase the bone height or volume from the maxillary sinus floor. This important preprosthetic surgical technique has been available for >15 years, making possible the creation of bone volume in the edentulous posterior maxilla for the placement of dental implants in surgically compromised cases. Substantial literature exists regarding the most efficacious way to increase the predictability of this surgical procedure, and reduce its associated complications.

A 5-year follow-up of 80 implants in 44 patients placed immediately after the lateral trap-door window procedure to accomplish maxillary sinus elevation without bone grafting.

Purpose: The present study was performed to evaluate the 5-year status of immediately placed implants subjected to maxillary sinus elevation without grafting.

Materials And Methods: Implants were placed in 2004 and 2005. A minimum of 3 mm of residual bone height (RBH) was required.

Implant placement immediately after the lateral approach of the trap door window procedure to create a maxillary sinus lift without bone grafting: a 2-year retrospective evaluation of 47 implants in 33 patients.

Purpose: The present study was undertaken to retrospectively evaluate the status of implants in patients subjected to a maxillary sinus lift and immediate implant placement without bone grafting.

Patients And Methods: Seventy-five implants were placed in 47 patients from 2000 to 2006. Lateral approach for the trap-door, open-window method for sinus lifting without placement of either autogenous bone grafts or allogeneic bone substitute was carried out.

Evaluation of Alginate coated Chitosan Membrane for Guided Tissue Regeneration.

Chitosan membranes prepared by a thermal induced phase separation method and then alginate was coated onto the membrane on one side by a modified dialysis apparatus to prepare alginate/chitosan membranes (A/C membranes). ESCA analysis, SEM observation and contact angle measurements were conducted to evaluate the differences existed in the surface properties. Besides, mechanical strength, degradation behavior and especially, cell adhesion test was also examined to survey the feasibility of using this type of A/C membrane in guided tissue regeneration (GTR) application.

Guided tissue regeneration for using a chitosan membrane: an experimental study in rats.

Barrier membranes are employed clinically to deflect the growth of gingival tissues away from root surface. They provide an isolated space over the regions with the defective tissues that allow the relatively slow growing periodontal ligament fibroblasts to be repopulated onto the root surface. Several makes of bioabsorbable membranes are now commercially available.
