Title: 14-3-3? expression in colorectal cancer is associated with increased tumor angiogenesis

Abstract:Background and study aim: 14-3-3? protein involved into multiple cellular processes. The aim of this study was to investigate the role of 14-3-3? protein in colorectal cancer (CRC) and its relationship with tumor angiogenesis. We also used CRC cell lines HCT116 and DLD1 to assess the biological function of 14-3-3?.Material and methods: In this study, 72 colorectal cancer specimens were investigated by immunohistochemical staining for CD105 and 14-3-3?. 14-3-3? was enforced expressed in CRC cell lines, and the effect of 14-3-3? on the expression of p-mTOR and p-GSK-3� was assessed by western blot.Results: The overexpression of 14-3-3? was found in 60 (83.3 %) colorectal cancer tissue samples. 14-3-3? expression in CRC was significantly associated with tumor differentiation (p= 0.001), pT stage (p= 0.001), and advanced pTNM stage (p= 0.002). CD105 overexpression were detected in 51 (70.8 %) CRC specimens. CD105 expression in CRC was significantly associated with tumor differentiation (p= 0.039), pT stage (p= 0.001), advanced pTNM stage (p= 0.000) and nodal status (p= 0.002). In addition, the overexpression of 14-3-3? was positively correlated with the expression of p-GSK-3� and p-mTOR in DLD1 and HCT116 cells.Conclusions: Our study suggested that 14-3-3? overexpression accompanied with angiogenesis, and associated with colorectal carcinoma progression, and the mechanism was probable associated with p-GSK-3� and p-mTOR signal pathway. Thus, targeting 14-3-3? and angiogenesis might be a new therapeutic strategy in colorectal carcinoma.

Title: Factors Affecting Learning Performance in Flipped Classroom: An Empirical Study Based on RCOI Framework

Abstract:Prior studies focused on the relationships among the factors affecting the\nflipped classroom\'s learning performance (FCLP), but few analyzed the factors that\naffect FCLP. This study constructed a four-dimension model of the factors affecting\nFCLP based on the revised community of inquiry (RCOI) framework and tested it in\nthree flipped classrooms (N=231) in a leading Chinese university. The analysis revealed\nthat learners\' perception of FCLP was affected by the social presence, teaching presence,\ncognitive presence, and learning presence in descending influence order. The cognitive\npresence acted as a full mediator between learning presence and FCLP and a partial\nmediator among teaching presence, social presence, and FCLP. The conclusion may\nprovide a theoretical and practical guide to the future teaching design and class\norganization of flipped classrooms.

Title: Justice and Equity in the New General Local Plans in Albania

Abstract:Equity in territorial planning is is a wellknown concept and of central importance in the theoretical debate and planning practice of Western countries. However, in Albania, the goal of justice and equality in territorial planning remains a new challenge, unaddressed in practice and far from the focus of academic research. This paper seeks to raise concerns about the evaluation of new local plans that have been drafted over the last decade in Albania regarding the criteria of justice and equality for urban development. The term equality, in the context of city planning, refers to the technique of conforming the territory and the developing real estate, for which the regulatory plan should evenly distribute the advantages and disadvantages of urban planning.. We argue that there is a gap in the legal framework in Albania which does not provide a methodology that enables the fair distribution of development rights through territorial plans. The new local plans drafted from 2013 onwards use Development Instruments such as land use and territorial development indicators reflecting the factual situation in some areas and unsubstantiated interests in others. In this regard, there is a need for a review of local territorial plans regarding the evaluation of the implementation of the principle of equality in the distribution of development rights. In a further perspective, the article suggests an integrated review of the legal planning framework including the legal provisions of sectoral legislation governing informal construction issues and property titles unresolved by the political regime of past decades. Related to the issue of equality of development law with property development rights, the article argues that an integrated solution of the legal framework of territorial planning and development by applying the criteria of justice and equality in the distribution of urban development rights, offers opportunities for resolving conflicts inherited from other legal acts, widely contested in connection with the denial of the right to territorial development, such as the law on the treatment of property and the law on the legalization of informal settlements.

Title: Optimization of inulin extraction from garlic (Allium sativum L.) waste using the response surface methodology

Abstract:Inulin is a polysaccharide with several applications within the chemical, pharmaceutical, and food industry. It is considered a dietary fibre that provides multiple health benefits. In this work, the yield of raw inulin obtained from garlic agro-industrial useless organic waste was maximized, by applying the response surface methodology in a central composite design (CCD), in which different distilled-water (DW)-to-garlic-agro-industrial-organic-waste (GAIOW) ratios (3 and 5 mL/g) and different temperatures (60 and 80 °C) were evaluated. Optimal condition was obtained with a DW/GAIOW ratio of 4.3 mL/g and a temperature of 80.2 °C. Under this condition, the quadratic model showed a maximum yield of crude inulin of 8.17 ± 0.89 g/100 g. Further, the CCD model obtained was validated with three additional experiments at the same optimal condition. The FTIR spectra of inulin obtained from garlic agro-industrial organic residues and chicory inulin showed similarities and differences, presumably related to the different degrees of polymerization of the fructans present.

Title: The Contribution of Reading Strategies to Mathematical Literacy of Students: A Comparison of Singapore, Australia, The United States of America, and Saudi Arabia based on PISA 2018 data

Abstract:This study investigates the contribution of three categories of reading strategies to 15 year old school students’ mathematical literacy. The data for Singapore, Australia, the United States of America, and Saudi Arabia were obtained from the Programme for International Student Assessment (PISA 2018). The multiple regression results showed that all the three types of reading strategies contributed significantly to mathematical literacy with much variation between the sub-strategies. The summary writing strategy category contributed best to students’ mathematical literacy in Saudi Arabia, Singapore, and Australia with beta values, 17.7%, 13.7%, and 10%, respectively whereas the reaction to email category (focused on critical thinking) was the best contributed category in the USA (7.3%). The findings further illuminate which specific strategies most strongly predict mathematical literacy across all four countries, and which distinguish the country with the best mathematical literacy performance (Singapore) and the lowest performer (Saudi Arabia). The issue is further discussed whether reading strategies have a direct contribution on mathematical literacy or not and how the answer might affect possible intervention policies to improve mathematical literacy in schools.




Abstract:COVID-19 has emerged as multifarious lung disease with various clinical presentations in addition with common cold and flu. The airway inflammation, bronchial hyper responsiveness and mucus secretion leading to airflow obstruction is characterized as cause of inconvenient breathing. Currently the CoV-2 is diagnosed with polymerase chain reactions and some biochemical techniques employed in virology but lung function tests are ignored. No one is still established serum biomarker to assess the severity of inflammation and obstruction of airways. Present study was conducted to evaluate clinical utility of serum Periostin level in Cov-2 infected patients in term of significant correlation of serum Periostin levels with absolute Eosinophil count and lung function test. Total 760 CoV-2 infected participants were subjected to study. Infection was further classified into mild, intermittent, moderate and severe types and 100 patients for each groups were studied. Patients with COPD or other type of allergy were excluded from the study. Patients from 18-60 years of age, diagnosed with asthma by a Pulmonologist and age and gender matched non-asthmatic adults were included in the study bearing CoV-2 infections. Absolute eosinophil count were determined by XN-1000 Sysmex hematology analyzer and serum Periostin level were measured with manual Elisa method. Lung function test was performed with spirometer (FEV1) at Ayub Teaching hospital. The data was entered and analyzed using SPSS 20.0. Comparison between two groups were calculated by sample t-test and correlation were calculated by person correlation coefficient. Study concluded that Serum periostin level and absolute eosinophil count were significantly correlated with severity of COVID-19 infections and can be used as surrogate markers for diagnosis and severity of disease.
