Differentiation of Human Umbilical Cord Derived Mesenchymal Stem Cells into Dopamine Producing Cells[ ]


Human umbilical cord tissue namely Wharton's jelly is one of the rich sources of mesenchymal stem cells(MSCs). MSCs are pluripotent cells that can differentiate into different types of cells including neural and dopaminergic cells. Thus MSCs hold great promise for different neurodegenerative diseases such as Parkinson's disease which result from the impairment and failure in generation of dopamine neurons in the substantia nigra of the mesencephalon. This work was aimed to study the efficacy of WJ-MSCs to differentiate into dopaminergic (DAergic) neurons in presence of all trans retinoic acid (ATRA) by determination of dopamine level. Flow cytometery analysis showed that MSCs were positive for CD90 and CD73 and negative for CD45 and CD34. Immunocytochemistry staining showed that the cells treated with ATRA were strongly expressed for MAP-2 and showed less expression for cells treated with neurobasal media only. Results from ELISA indicated that dopamine levels were markedly increased in the ATRA-treated groups.

Glycomacropeptide: an alternative to management of phenylketonuria[ ]


Phenylketonuria is a metabolic disorder categorized by high level of phenylalanine in blood due to mutations in a gene involved in phenylalanine metabolism. The primary management of disease is lifelong restriction of protein food along with utilizing food comprising of synthetic amino acids. Compliance with synthetic food is poor leading to neurological problems. Glycomacropeptide, 64 amino acid proteins, provide a new standard because it does not contain phenylalanine in its pure form. GMP provides more acceptable and physiological source of protein as compared to synthetic amino acids. GMP is probiotics, reduces harmful gut bacteria, decrease renal load, improves protein utilization and satiety and improves bone strength size and strength. Advances in biotechnology will ultimately lead transition from synthetic amino acids to intact protein for the dietary management of phenylketonuria.

The daily average waste generation in Sir Salimullah Medical College (3885.5 kg) was found greater than Sumona Hospital (442 kg), in which non-hazardous wastes (79.96% - 73.11%) were greater in amount than hazardous waste (20.04% - 26.89%). The study also shows that existing medical waste management practices is not up to the mark. So, there is a need for improvement of handling and disposal methods of medical waste in all the health care facilities in Bangladesh.

Attribute-Based approach for Flexible Access control in Cloud Computing with Hierarchical Structure[ ]


Cloud storage enables users to remotely store their data and enjoy the on-demand high quality cloud applications without the burden of local hardware and software management. Though the benefits are clear, such a service is also relinquishing users’ physical possession of their outsourced data, which inevitably poses new security risks towards the correctness of the data in cloud. In order to address this new problem and further achieve a secure and dependable cloud storage service, we propose in this paper We develop a new cryptosystem for fine-grained sharing of encrypted data that we call Key-Policy Attribute-Based Encryption (KP-ABE). In our cryptosystem, ciphertexts are labeled with sets of attributes and private keys are associated with access structures that control which cipher texts a user is able to decrypt. Attribute-based encryption (ABE) has been envisioned as a promising cryptographic primitive for realizing secure and flexible access control. HASBE extends the ASBE algorithm with a hierarchical structure to improve scalability and flexibility while at the same time inherits the feature of fine-grained access control of ASBE.

Linking Financial Management Practices To Financial Literacy: Evidence From Turkey[ ]


Financial literacy emphasizes the ability of understanding financial conditions, practices, rules and norms to make informed financial decisions. Advocates heralded the need for increased financial literacy as means to improve financial preparedness and financial decision-making processes since low levels of financial literacy is an international phenomenon in developed and developing countries. Using data from a major state university in Turkey, this study examines the importance of financial literacy on four financial management practices -saving, non-investment borrowing, comparing financial services before buying and following financial trends- in a single model. The regression analysis results showed that all explanatory variables were related to financial literacy except the non-investment borrowing. The findings highlight the importance of financial literacy as an input for financial success and desired financial outcomes. Future research directions and limitations were discussed.

Understanding Publicness Degree of Cairo’s Public Spaces[ ]


Public spaces in Cairo witness a significant transition in their articulations since the state imposed its power over their development till the empowerment of the elite class over the same. This paper develops and validates an evaluation sheet, with measurable indicators, used to understand and evaluate the publicness degree of public spaces through discussing two features: accessibility degree and social diversity degree. Expo Square and Festival Square from metropolitan Cairo are investigated to represent public-sector development (state power) and private-sector development (elite power) respectively. Through this investigation, the degree of publicness is discovered via the evaluation sheet to understand how different empowered actors could affect space publicness. The research concludes that in Cairene context, the private-sector produces public spaces with less degree of publicness according to his profit-making plans.
