This exploratory investigation describes the perceptions of students and teachers on how the Philippines can be ushered towards national development and ASEAN competitiveness through technology integrated basic science education. Qualitative and quantitative data were gathered from the survey instruments, focused group discussions and responses to open ended questions of 779 students and 75 teachers. The survey instruments were adapted from the surveys done by P21 organization. Results revealed that while students see technology as an important factor in their learning, they fail to appreciate the extent of its application in their education. Their level of satisfaction on technology use is high no matter how limited the availability and use of technology in their school is. They still lack the awareness of the use of technology as an aid to understand science and mathematics concepts. On the other hand, science teachers’ notion of 21st century technology and software applications in the classroom are primarily about personal gadgets like laptops, tablets, SMARTPHONES, computers and touch screen devices. They also recognize the limited use of technology in their schools and hardly consider computer software as technology for science. They expressed their need for training on modern science laboratory instruments and access to modern technology primarily the personal computers and other electronic gadgets. They believe that the schools have limited means for technology integrated curriculum because of lack of access to electronic gadgets. © 2017 American Scientific Publishers All rights reserved.

The kinetics of the reduction of hexavalent to trivalent chromium using ferrous sulphate (FeSO4) under acidic condition was studied using two methods of UV-Visible spectroscopy - the HACH and the Lambda Series. Potassium dichromate (K2Cr2O7) was used as source of Cr6+. Due to complexity and time consuming steps of the Lambda Series, the HACH Method was employed as screen test. As soon as the trial gave good results from the HACH method, the Lambda series was performed. Comparison of the results was carried out and several differences were noted. The study was composed of four parts - kinetics of the reduction of potassium dichromate by ferrous sulphate, determination of the rate and order of reaction, analysis of chromium hexavalent using the Diphenylcarbazide Method of HACH and Lambda Series UV-Vis spectrometer and determination of rate constant. There are several trials performed to arrive at the procedure for the reduction of hexavalent chromium via ferrous sulphate presented herein. Same is true with the rate and order of reaction. At a ratio of 1:10 of potassium dichromate to ferrous sulphate, a good result for the rate and order of reaction was obtained. Results from the procedures showed that the overall rate of reaction is first order - that is zero order with respect to K2Cr2O7 and first order with respect to FeSO4. In the kinetic study, a ratio of 3:5 K2Cr2O7 to FeSO4 also showed good results in which the rate constant was computed to be 1.7 × 10-4 per second. However this result was only obtained from the HACH Method. Lambda Series showed different results in the computation of rate constant.

Environmental toxicants invariably affect all biological organisms resulting to sufferings ranging from subclinical to debilitating clinical conditions. This novel research aimed to determine the toxic burdens of increased environmental elements in some vital organs/tissues of the wild animals (starling, owl, crow and pigeon), exposed to air polluted environment were assessed using particle induced X-ray emission and histopathological approaches. The presence of significantly elevated amounts of elemental toxicants namely: Aluminum (Al), Chlorine (Cl), Iron (Fe), Potassium (K), Magnesium (Mg), Manganese (Mn), Silicon (Si) and Vanadium (V) from the skin, muscle, lungs, liver and kidney of sampled animals were in concurrence with the observed histopathological changes. The skin of sampled starling, owl, pigeon and crow spotlighted highly significant increase (P < 0.001) in Al, Cl, Mg and Si. Muscle samples with myodegenerative lesions and mineral depositions highlighted substantial augmentation (P < 0.001) in the amount of Al, Fe, Mn, Si and V. The lungs of starling, owl, and pigeon were severely intoxicated (P < 0.001) with increased amount of Al, Fe, K, Mn and Si producing pulmonary lesions of congestion, edema, pneumonitis and mineral debris depositions. Liver samples revealed that the sampled animals were laden with Cl, Fe, Mg, Mn and V with histopathological profound degenerative changes and hepatic necrosis. Kidney sections presented severe tubular degenerative and necrotic changes that may be attributed to increased amounts of Cl and Fe. These current findings implied that the environmental/elemental toxicants and the accompanying lesions that were discerned in the organs/tissues of sampled birds may as well be afflicting people living within the polluted area. Further assessment to more conclusively demonstrate correlations of current findings to those of the populace within the area is encouraged. © 2014 Her Majesty the Queen in Right of United Kingdom.

The effectiveness of electrodialysis (ED) in removing inorganic arsenic (As) from aqueous solution was investigated. A tailor-made ED stack was used to perform current-voltage and optimization experiments in a recirculating batch mode. Samples were pre-oxidized with NaClO using 1:2 sample to oxidant weight ratio (RS:O) to transform 100% of As(III) to As(V) in 180 seconds. A high feed water conductivity of 1500 μS/cm and a low feed water conductivity of 800μS/cm had limiting currents of 595 mA and 525 mA, respectively. Optimum experimental conditions that provided maximum As separation were applied potential (E) of 12 V, feed flow rate (Q) of 0.033 L/s, feed concentration (C) of 662.0 μg L-1, and operating time (t) of 45 min, the most significant ones were applied potential, feed concentration and operating time. Model confirmation experiments showed a good agreement with experimental results with only 0.031% error. The total As in the diluate stream was 4.0 μg L -1, consisting of an average of 3.0 μg L-1 As(V) and 1.0 μg L-1 As(III). © 2014 Copyright Taylor and Francis Group, LLC.

Cell culture technology is immensely useful in somatic hybridization, induction of mutations, cloning of specific isolates and maintenance of strains of defined genotypes. However, its application in strain improvement of some tropical red macroalgae has been limited due to the difficulty of isolating viable cells from their complex intercellular matrices. A simple, non-enzymatic technique of isolating somatic cells was developed for Kappaphycus spp. and Echeuma denticulatum. Surface-sterilized tissues (0.1 g fresh weight, 2.0 mm thick discs) from subcortical and medullary layers were treated with 3% NaOH, 3% KOH, or hydrogen peroxide in phosphate buffer solution (PBH2O2). Tissues of K. alvarezii treated with PBH2O2 softened after 5 h of treatment and completely dissociated after 12 h. Viable cell counts (VCC), determined through staining with Evan’s blue, were significantly higher (2.4 × 105 cells g−1 fresh weight tissue) in K. alvarezii (‘tambalang’ strain) treated with PBH2O2 compared with tissues treated with carrageenase from a marine bacterium. © 2014, © 2014 British Phycological Society.

Superantigens and genetic factors may play roles in the etiology and susceptibility to Kawasaki disease (KD). To investigate these roles, percentages of TCR-Vβ2+ T cells were compared by flow cytometry using anti-Vβ2 monoclonal antibodies and genotyping was done on HLA-DRB1 exon 2, the -308 site of the TNF-α promoter region, and ITPKC SNP rs28493229 by polymerase chain reaction followed by direct sequencing. There were higher percentages of Vβ2+ T-cells in KD patients (9.5 ± 2.15%) compared to healthy controls (7.25 ± 1.48%) (P<0.05, Student's t-test, n=6-8/group). However, no polymorphisms were observed in exon 2 of HLA-DRB1 and in the -308 region of the TNF-α promoter. The ITPKC SNP rs28493229 G/C polymorphism was observed in 1 KD patient and 4 healthy controls. This study suggests that KD etiology may be associated with a superantigen and that HLA-DRB1 exon2, TNF-α -308 region and ITPKC SNP rs28493229 may not be associated with KD. This is the first study investigating Vβ2+ T cells and candidate genes involvement among Filipino KD patients.

This study aims to develop a novel method of beveled osteotomy for lateral orbitotomy using a customized 21-mm stainless steel rotating saw in lateral orbitotomy and to evaluate the outcome of a novel beveled osteotomy in lateral orbitotomy. This article presents a case series (19 orbits from 18 patients) of lateral orbitotomies for excision biopsy of orbital neoplasms, over a 10-year period (from September 2001 to October 2011). It is a retrospective observational study. The surgeries were performed under the primary service of one surgeon (M. D. D. S.), the author of this study. All patients were treated via beveled osteotomies in lateral orbitotomy using a stainless steel, 21mm diameter, customized rotating bone saw. Preoperative and postoperative measurements were tabulated and statistically analyzed. The case series demonstrated that beveled osteotomies in lateral orbitotomy using a stainless steel, 21mm diameter, customized rotating bone saw was technically possible and provided access to lateral subperiorbital, peripheral, and central surgical spaces. The exposure was ample for excision biopsy of all neoplasms in this study. No patient needed the use of miniplate hardware in repositioning the lateral orbital wall nor complained of a palpable deformity of the lateral orbital wall. The wound healing was rapid, with minimal tissue distortion or scars. There were two patients who developed skin burns, but neither required a cosmetic surgery to correct scarring from the burn. It was concluded that the modified technique of beveled osteotomies in lateral orbitotomy provides excellent access to the lateral subperiorbital, peripheral and central surgical spaces. The exposure was adequate for excision biopsy of all neoplasms in this study. The technique promotes osseous union without the use of miniplate hardware. The use of a stainless steel 21mm diameter customized rotating bone saw facilitated the successful outcome of the beveled technique.

The study determined the knowledge of the College of Science faculty on the goals of science education, the importance of each goal as perceived by the faculty, how often each goal is used and operationalized for teaching/learning purposes. The results revealed that teachers' level of knowledge on the science goals and objectives was minimal. The faculty perceived scientific knowledge and methods very important and used it frequently in teaching. They used lecture for students to acquire scientific knowledge and laboratory activities to develop scientific methods. They did not know how to operationalize societal issues, personal needs, and career awareness when teaching their subject matter. The problems that prevent them from pursuing the goals were lack of instructional materials, lack of interest and negative attitude of students, lack of facilities, and knowledge in handling laboratory apparatus. Teachers do not utilize strategies that can facilitate the students' construction of meaning and ideas. © 2013 Penerbit UTM Press. All rights reserved.

Palliative Care | Year: 2013

Towards the end of life, physicians face dilemmas of discontinuing life-sustaining treatments or interventions. In some circumstances, these treatments are no longer of benefit, while in others the patient or family no longer want them. The physician plays an essential role in clarifying the goals of medical treatment, defining the care plan, initiating discussions about life-sustaining therapy, educating patients and families, helping them deliberate, making recommendations, and implementing the treatment plan. Communication is key. It should be clarified that when inevitable death is imminent, it is legitimate to refuse or limit forms of treatment that would only secure a precarious and burdensome prolongation of life, for as long as basic humane, compassionate care is not interrupted. Agreement to DNR status does not preclude supportive measures that keep patients free from pain and suffering as possible. Acceptable clinical practice on withdrawing or withholding treatment is based on an understanding of the medical, ethical, cultural, and religious issues. There is a need to individualize care option discussions to illness status, and patient and family preferences, beliefs, values, and cultures. The process of shared decision making between the patient, the family, and the clinicians should continue as goals evolve and change over time © the author(s), publisher and licensee Libertas Academica Ltd.
