Ovarian Cancer Identification Based on Feature Weighting for High-Throughput Mass Spectrometry Data
Abstract:
An important use of proteomics data from Mass Spectrometry (MS) is the classification of tumor types with respect to peptides in specific cancer types. It is highly critical to find an optimal set of markers among specific cancer peptides whose expression can be clinically utilized to build assays for the diagnosis or to track the progression of specific cancer types. A number of feature selection algorithms have been proposed to obtain the classification of MS data. In this article, we proposed an improved feature selection algorithm based on feature weighting. Relief algorithm can calculate the weight of different features according to the correlation between their characteristics and categories. F-score is a simple filter-based feature selection method by evaluating how two sets of real numbers discriminate from each other. The main goal of this paper is to introduce a new feature weighting selection algorithm combining score from...
Stress in High School Students: A Descriptive Study
Abstract:
School is a competitive place where people have many duties and responsibilities. This requires coping abilities to manage academic stress efficiently. a) Determine the general level of stress among high school students; b) identify the students’ main sources of stress; c) identify the students’ main responses to stress; d) determine if students have protections against or risk factors for stress. The stress levels and the main responses to stress of 335 high school students, aged 15–19 years, were surveyed using Nowack’s Stress Profile. Most of the students reported normal (54%) or lower (39%) stress levels, but women reported significantly ...

New Pain Management Procedure after Total Knee Arthroplasty: Gonyautoxins are Safe and Effective after A Single Intra-Articular Infiltration
Abstract:
To evaluate the effect of a single intraarticular dose of Gonyautoxins for pain control after Total Knee Arthroplasty (TKA). 30 consecutive patients with osteoarthritis with Kellgren & Lawrence level of two or more, who required TKA, were enrolled. Subjects receive a single intra-articular infiltration of 40 µg dose of Gonyautoxins, immediately after TKA wound closure. The pain was measured with the Visual Analog Scale (VAS). Additionally, the range of motion at 12, 36, and 60 hours and hospital stay length were recorded. Results were compared to the 2014 TKA cohort. 25 patients (83.33%) achieved succ...
The Initial Result Of The First Living Donor Lung Transplantation Case In Vietnam
Abstract:
Lung transplantation is an established treatment option for patients of end-stage lung diseases. Leading indications include chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis and bronchiectasis, pulmonary arterial hypertension. Living donor lung transplantation (LDLT) was indicated for patients who experience a decline in physical condition and have limited life expectancy and had the better result than from brain dead. The first case of LDLT in Vietnam is 7 year olds boy with difuse congenital bronchiectasis, chronic respiratory failure and cor pulmonale. The right and left lower lobes from father and relative uncle are implanted in a recipient in place of whole right and left lung. The initial result of this recipient showed that lung function recuperated quickly and had no early complications. After 12 months surgery, the recipient had normal physical exercise capacity, subclinical tests in normal limits and no respiratory symptoms, opportu...
Efficacy of The Immunotargeting Therapeutic Antibody Trastuzumab in HER2-Positive Advanced Gastric Cancer: A Meta-Analysis
Abstract:
Gastric cancer is one of the most common types of cancer in the world, usually diagnosed at an advanced stage. Despite the advances in specific anticancer agents' development, the survival rates remain modest, even in early stages. HER2 overexpression was identified on 15% - 20% of gastric cancer patients. Trastuzumab-based chemotherapy provides obvious efficacy improving outcomes of HER2 positive gastric cancer patients. We performed a meta-analysis to estimate the efficacy of the addition of trastuzumab over chemotherapy. We identified randomized controlled trials (RCTs) which compare the addition of trastuzumab therapy to chemotherapy alone reporting progression-free survival (PFS), time to progression (TTP), overall survival (OS), and/or response rates as our eligible trials. Night trials including 1101 patients were eligible for analysis. Trastuzumab therapeutic partners were cisplatin (9 RCTs), 5-fluorouracil (8 RCTs), capecitabine (6 RCTs), irinotecan (1 RC...
Malaria: An Unseen Enemy Threatening to Mankind
Abstract:
The research work on malarial infection and malarial treatment has been increased tremendously over the years due to increased resistance of parasites to antimalarial drugs. To overcome the developed resistance, antimalarial drugs are used in combination. But eventually the amount of drugs administered increase with the resistance and extend to adverse effects. Many innovative, sophisticated delivery systems have been developed to increase the adequacy, competency and efficiency of antimalarial drugs. But it is predicted that these new inventions will also acquire resistance with time. Globally, it is seen that the countries which have low standards of hygiene have high levels of malarial infection. There are various antimalarial techniques developed and are slowly being adopted worldwide. But the first step is to maintain the hygiene and cleanliness so that mosquitoes will not harvest.
Study of Neuropilin-1/Cd304 Expression in Leukemogenesis
Abstract:
Neuropilins are transmembrane glycoproteins that act as receptors for vascular endothelial growth factors (VEGF) and are involved in the process of tumor angiogenesis. Its importance in hematological malignancies such as acute leukemia (AL) remains to be elucidated. The aim of this study was to evaluate the significance of neuropilin-1 expression in acute myeloid leukemia (AML) and acute lymphocytic leukemia (ALL) patients by flowcytometry and the difference between both groups of acute leukemia. Bone marrow aspirates of 52 patients with acute leukemia, 29 patients with de novo AML and 23 ALL patients were examined in this study. 15 subjects with non-hematological malignancy serving as the control group were also included. Neuropilin-1 expression by flow cytometry showed a highly significant increase in de novo AML and ALL patients with a mean of 37.9 ± 20.92% and 32.33±19.8%, respectively, compared to control group’s mean of 11.51 ± 3.04% (p= 0.001, 0.006). ...
General Evolution of the Universe Driven by Attraction and Four Levels of Biological Evolution as its Essential Part
Abstract:
A strict definition of the hierarchy of material systems is formulated. Based on this definition, the main hierarchical structure of the Universe was divided to 15 levels belonging to 2 branches. Process of the Universe evolution (megaevolution) is considered as hierarchogenesis, i.e., a process of new hierarchy levels formation. The main driver of the hierachogenesis is an attraction that takes different forms for different steps of the megaevolution. Duration and time of each this step on the Universe timeline were estimated using the data of the other investigators. Biological evolution is considered as essential part of the general megaevolution where symbiosis plays role of the hierarchogenetic attraction. Semantic consideration of the hierarchogenesis allowed to build a mathematical model of its dynamics. It appeared that this model describes general megaevolution of the Universe well enough to estimate time of macromolecules appearance, that is still unknow...
