The aim of this study is to develop a polymeric microcarrier (MC) for obtaining a higher cell density of Vero cells in spinner vessel. Different types of gelatin; bovine (BG), fish (FG), cationized bovine (CBG) and cationized fish (CFG) were covalently immobilized on carboxyl group containing polystyrene (COOH-PS). Their performance was evaluated b

Cell rupture is one of the earlier steps in downstream processing which are required for the recovery of biological products that are located inside cells. Cells could be disrupted either by using chemicals or mechanical method. In this study, cell rupture was carried out by mechanical force using High Pressure Homogenizer (HPH). The aim of this st

ترنو هذه الورقة إلى المقاربة بين الأحداث التاريخية لاستقلال أندونيسيا كما سجلت على أرض الواقع، وبين الأحداث التي رواها الأستاذ علي أحمد باكثير في مسرحيته "عودة الفردوس"؛ وذلك في سبيل إيضا

Fourteen hundred years ago al-Isra’ wa al-Mi‘raj or ‘The Night Journey’ brought to the world something that changed the course of history. The Isra’ Mi‘raj is considered a sign of Allah’s power by the God conscious. Therefore, this magnificent journey which contains a thousand and one wisdoms and miracles is very significant in Islam

Purpose – The purpose of this paper is to assess the existing facilities maintenance management practices and processes in public hospitals, in accordance with the concession agreement (CA), in order to identify the current performance status. Design/methodology/approach – A case study is conducted in one district hospital in Malaysia to assess

Manganese-doped biphasic calcium phosphate (Mn-doped BCP) powders have been synthesized via solgel technique. The Mn-doped BCP powders were studied for their phase behaviour at different concentrations of Mn (0, 0.01, 2, 5 and 15 mol%) and calcination temperatures (500–1200 ◦C). For all the Mn concentrations, the X-ray diffraction (XRD) reveale

Polystyrene failed to provide any reactive functionality of surface hydrophilicity that is capable of binding proteins. It is known that polystyrene must be chemically modified to make its surface amenable to covalent crosslinking with protein. Approach: The aim of this study was to investigate the effects of UV/ozone treatment on gelatin coating.

The fact of microcarrier (MC) culture introduces new possibilities and makes possible the practical high-yield culture of anchorage-dependent cells has generated a considerable focus in this study. The objective of this research was to study the comparison of Vero cell growth on different types of commercial microcarriers; Cytodex-1, Cytodex-3, Hil

This paper discusses the fabrication of microfluidic channels using micro end milling and micro electrical discharge (ED) milling on metals and polymers. The width of the microchannels fabricated by micro end milling was 100-800 µm with 1-2 aspect ratio. The average surface roughness values were 100-200 nm and 80-120 nm on metals and polymers resp
