Students’ Level of Engagement in Learning Technology and Livelihood Education in Blended Learning Modality

Student engagement is the amount of attention, interest, curiosity, and positive emotional connections that students have when they are learning whether in the classroom or on their own (Sousa, 2016). This study aimed to determine the students’ level of engagement in learning Technology and Livelihood Education (TLE). A survey was conducted among the randomly selected Junior High School Students of St. Paul University Surigao. Based on the findings, the researcher concluded that the students were highly engaged in learning TLE in a blended learning environment, specifically in the behavioral, cognitive, and emotional engagement. It was also concluded that the respondents’ age, sex, and grades are not significantly correlated to their level of engagement. Therefore, it is hereby recommended that teachers may continue to prepare tasks and activities that would engage the students in learning TLE, focusing more on their cognitive engagement. Similar studies may be conducted where additional variables will be included, and teachers may be taken as respondents for cross validation

Control of bleeding in surgical procedures: critical appraisal of HEMOPATCH (Sealing Hemostat)

Kevin Michael Lewis,1 Carl Erik Kuntze,2 Heinz Gulle3 1Preclinical Safety and Efficacy, Baxter Healthcare Corporation, Deerfield, IL, USA; 2Medical Affairs, Baxter Healthcare SA, Zurich, Switzerland; 3Surgical Sciences and Engineering, Baxter Medical Products GmbH, Vienna, Austria Abstract: The need for advanced hemostatic agents increases with the complexity of surgical procedures and use of anticoagulation and antiplatelet treatments. HEMOPATCH (Sealing Hemostat) is a novel, advanced hemostatic pad that is composed of a synthetic, protein-reactive monomer and a collagen backing. The active side is covered with a protein-reactive monomer: N-hydroxysuccinimide functionalized polyethylene glycol (NHS-PEG). NHS-PEG rapidly affixes the collagen pad to tissue to promote and maintain hemostasis. The combined action of the NHS-PEG and collagen is demonstrated to have benefit relative to other hemostatic agents in surgery and preclinical surgical models. This paper reviews the published investigations and case reports of the hemostatic efficacy of HEMOPATCH, wherein HEMOPATCH is demonstrated to be an effective, easy-to-use hemostatic agent in open and minimally invasive surgery of patients with thrombin- or platelet-induced coagulopathies. Keywords: HEMOPATCH, hemostasis, surgical hemostasis, sealing, surgical sealan

Analysis of primary T cell responses to intact and fractionated microbial pathogens

Freshly isolated human T lymphocytes were tested for their response to mycobacteria, mycobacteriallysates, 2 dimensional (2D) PAGE separated mycobacteriallysates, leishmania and defined leishmanial antigen preparations. While,o T cells proliferated vigourously in the presence of mycobacteria and mycobacteria derived lysates, a significant stimulation from 2 D gel separated lysates was not detected. In addition '10 T cells failed to respond towards leishmania or leishmanial components. In the ab T cell compartment some donors, presumably according to their state of immunity against mycobacteria, responded to mycobacteria, mycobacterial lysates and 2 D gel separated mycobacterial lysates. Neither freshly isolated '10 T cells nor ab T cells from naive donors did mount a significant immune response against leishmania

Cholecalciferol (vitamin D3) prevents postoperative adhesion formation by inactivating the nuclear factor kappa B pathway: A randomized experimental study

Background Postoperative peritoneal adhesions are major complications of abdomino-pelvic surgeries. We aim to investigate the preventive and therapeutic effects of cholecalciferol (vitamin D3) supplementation on postoperative peritoneal adhesion (PPA) in a rat model. Materials and methods This randomized, controlled, single blinded animal study was performed in university laboratory. Thirty-two female Wistar albino rats were randomly separated into four equal groups as, group 1: (21-d vitamin-D treatment group), group 2: (21-d corn oil group), group 3: (14-d vitamin-D treatment group), and group 4: (control group). Uterine horns were traumatized with bipolar cautery for adhesion formation process. On postoperative day 14, all the animals were sacrificed and evaluated for adhesions. Adhesion extent, severity, degree, and total adhesion scores were evaluated macroscopically. Histopathologically, adhesions were evaluated for inflammation, fibrosis, and NF?B (nuclear factor kappa b) staining. Results On postoperative day 14, we found lesser peritoneal adhesion severity, degree, extent, and total adhesion scores with vitamin-D administration compared with control and corn oil-treated groups; the difference was statistically significant (P < 0.001). Histopathologic adhesion scores of inflammation and fibrosis were statistically different among the four groups (P < 0.001). NF?B staining was markedly increased in control and vehicle groups. The NF?B staining scores were statistically different between the groups (P < 0.001). The intensity of NF?B staining was lower in both vitamin 14 and 21-d vitamin-D groups. Conclusions Vitamin D as a supplement and as a therapeutic medicine decreases the formation of PPA in an animal model. In future studies, the association of vitamin D deficiency and PPA should be studied. In addition, vitamin D should be investigated in future clinical studies for the prevention of PPAs. © 2015 Elsevier Inc. All rights reserved
