Antibacterial Activity of Biodegradable Plastic from Chromolaena odorata (Pokok Kapal Terbang) Leaves

The aim of this research project was to develop antimicrobial films from blends of C. odorata and PVA and test the films for microbial activity using broth dilution methods for Gram-negative (E. coli) and Gram-positive (S. aureus) bacteria. The result shows that CO/PVA80 successfully inhibit the growth of target bacteria. In antibacterial activity analysis, CO/PVA80 showed 50% higher compare with pure PVA film, PVA100. Other than that, the high percentage of PVA in the blend films, the greater the thickness, Tensile Strength (TS) and Young’s Modulus (YM), while the Elongation Break (EB) of the prepared films decreased. The 0.5 mm CO/PVA80 film shows a good result in mechanical properties which is TS 6.55 MPa, YM 182 MPa and EB is 7.47%. A CO/PVA80 were show a smooth texture, lacked of macropore and good characteristic with a SEM analysis. These results suggest that CO/PVA80 films have good compatibility to form an antimicrobial film as a new material for medical application especially for wound healing.

Efficacy of Incorporation Platelet Rich Plasma into Gelatine Hydrogel Scaffold between Impregnated and Drop Method

Tissue Engineering which involve three main component such as scaffold, platelet-rich plasma (PRP) and cells is expected to support in bone regeneration. Gelatin hidrogel scaffold is planted have a function as cell environment and PRP provide growth factor to support differentiation of cells. The success of tissue engineering is affected by number of PRP which is contained in scaffold. The purpose of this study is to compare the incorporation process between impregnated and drop method to gelatin hidrogel scaffold. PRP was prepared from three donors of whole blood, and twice sentrifugation by 450 rcf for 5 minutes and 1500 rcf for 7 minutes. PRP was incorporated into 3 gelatin hidrogel scaffolds for each methods. The remnant of PRP which didn’t incorporate were calculated the number of platelet with giemsa stainning. Platelet which loaded were the reduction result of number platelet before incorporate with platelet remnant. Data of the result were analyzed using independent sample t test. Result show the significant was 0.262 (p>0.05) there’s no significane different between impregnated and drop method for incorporating PRP into gelatin hidrogel scaffold. The number of platelet which incorporated in gelatin hidrogel scaffold were effected by characteristic of scaffold such as structure, interface adherence, porosity and swelling ability. The good characteristic of scaffold could be obtain from synthesis and good fabrication technique.

Ethical and legal problems of commodification of biomaterials in the development of genomics and genomic medicine

В статье рассмотрен ряд этико-правовых проблем коммодификации биоматериалов в процессе развития геномики и геномной медицины. Показано, что биоматериалы в современном мире рассматриваются как объекты имущественного и патентного права и становятся источником получения прибыли. Зачастую это приводит к появлению казусов, связанных с защитой прав индивида, являющегося источником происхождения биоматериалов. Выдвинут тезис о том, что ситуация, связанная с оборотом биоматериалов, отражается в различных модусах отношений между индивидом, наукой и обществом, с характерной для каждого из них артикуляцией приоритета личного или общественного блага. The article considers a number of ethical and legal problems of commodification of biomaterials in the development of genomics and genomic medicine. It is shown that biomaterials in the modern world are considered as objects of property and patent law and become a source of profit. Often this leads to the appearance of incidents related to the protection of the rights of the individual, which is the source of origin of biomaterials. The thesis is put forward that the situation associated with the circulation of biomaterials is reflected in various modes of relations between the individual, science and society, with the articulation of the priority of a personal or public good characteristic of each of them.

Calculations with graded perverse-coherent sheaves

In this paper, we carry out several computations involving graded (or ${{\mathbb {G}}_{\textrm {m}}}$-equivariant) perverse-coherent sheaves on the nilpotent cone of a reductive group in good characteristic. In the first part of the paper, we compute the weight of the ${{\mathbb {G}}_{\textrm {m}}}$-action on certain normalized (or ‘canonical’) simple objects, confirming an old prediction of Ostrik. In the second part of the paper, we explicitly describe all simple perverse-coherent sheaves for $G = PGL_3$, in every characteristic other than 2 or 3. Applications include an explicit description of the cohomology of tilting modules for the corresponding quantum group, as well as a proof that $\textsf {PCoh}^{{{\mathbb {G}}_{\textrm {m}}}}({\mathcal {N}})$ never admits a positive grading when the characteristic of the field is greater than 3.
