Kenaf cellulose-based poly(amidoxime) ligand for adsorption of rare earth ions

引用

Rare Metals 2019年第3期38卷 259-269页

作者： md Lutfor Rahman mohd Sani Sarjadi Sazmal Effendi Arshad Mashitah M. Yusoff shaheen M. Sarkar Baba Musta Faculty of Science and Natural Resources Universiti Malaysia Sabah Faculty of Industrial Sciences and Technology University Malaysia Pahang

A well-known adsorbent, poly(amidoxime)ligand, was prepared from polyacrylonitrile(PAN) grafted kenaf cellulose, and subsequent characterization was performed by Fourier transform infrared spectroscopy(FTIR),field emission scanning electron microscope(FESEM) and inductively coupled plasma mass spectrometry(ICP-MS).The adsorption capacities of the prepared ligand for rare earth metals are found to be excellent, with adsorptions of La^(3+), Ce^(3+), Pr^(3+), Gd^(3+) and Nd^(3+) experimentally determined to be 262, 255, 244, 241 and 233 mg·g^(-1), respectively, at pH 6. The experimental values of the adsorption of rare earth metals are well matched with the pseudosecond-order rate equation. The reusability of the adsorbent is examined for seven cycles of sorption/desorption,demonstrating that the proposed adsorbent could be reused for over seven cycles without any significant loss in the original removal capability of the ligand.

Lanthanide-ion imprinted polymers（L-IIPs） were synthesized by stoichiometric amounts of rare earth ions and the cavities in the polymers were created for the corresponding lanthanide ions. The maximum sorption capacities were estimated to be 125.3, 126.5, 127.6, 128.2 and 129.1 mg/g for Pr, Nd, Sm, Eu and Gd, respectively at p H 6. In the selectivity study, the L-IIPs exhibited good selectivity to the specific rare earth ions in the presence of coexisting cations. The imprinting results were found to be excellent with some rare earth ions over other competitor rare earth ions with the same charges and close ionic radius.

Phytocompounds of Anonna muricata leaves extract and cytotoxic effects on breast cancer cells

引用

Asian Pacific Journal of Tropical Medicine 2018年第12期11卷 659-665页

作者： Husna Syakirah Ab Rahman Wan Suriyani Wan-Ibrahim Norzila Ismail Tuan Nadrah Naim Tuan Ismail Siti Farhanah mohd-Salleh Michael Pak-Kai Wong mohd Ridzuan Abdul Samad mohd Nizam md Hashim Department of Surgery School of Medical Sciences Universiti Sains Malaysia Department of Pharmacology School of Medical Sciences Universiti Sains Malaysia School of Dental Sciences Universiti Sains Malaysia

Objective: To identify the phytochemical compounds from Annona muricata(A. muricata) and to determine their in vitro anti-proliferative activities against breast cancer cells, MCF7 and mdA-MB-231. Methods: A. muricata leaves were successively extracted by soxhlet method using n-hexane, ethyl acetate and methanol, and decocted with water. Each extract was analysed by gas chromatography mass spectrometry(GCMS) and characterized with Wiley and NIST library searches. Anti-proliferative activity of each extract was evaluated on MCF7 and mdA-MB-231 breast cancer cells using MTT assay. Results: The GCMS analysis of different solvent extracts of A. muricata leaves showed presence of different chemical groups of compounds such as steroids, terpenoids, phenolic compounds, sugars, sugars alcohol and others including vitamin E. Ethyl acetate leaves extract exhibited the lowest IC_(50) value on the mdA-MB-231 breast cancer cell and n-hexane leaves extract showed the the lowest IC_(50) value on the MCF-7 breast cancer cell. Conclusion: Steroids and phenolic compounds were the main phytocompound groups identified from all A. muricata leaves extracts. The antiproliferative activity of n-hexane and ethyl acetate extract towards breast cancer MCF7 and mdA-MB-231 respectively might be due to the presence of biologically active compounds in the extracts, hence, providing some scientific evidences of the effectiveness of its traditional usages.

Diagnostic evaluation of optical coherence tomography parameters in normal, preperimetric and perimetric glaucoma patients

International Journal of Ophthalmology(English edition) 2022年第11期15卷 1782-1790页

作者： Aimy Mastura Zurairah Yusof Othmaliza Othman Seng Fai Tang mohd Rohaizat Hassan Norshamsiah md Din Department of Ophthalmology Tuanku Mizan Armed Forces HospitalKuala Lumpur 53300Malaysia Department of Ophthalmology UKM Medical CenterJalan Yaacob LatifCheras 56000Kuala LumpurMalaysia Department of Community Health UKM Medical CenterJalan Yaacob LatifCheras 56000Kuala LumpurMalaysia

AIM: To compare the diagnostic ability of glaucoma parameters measured by the optical coherence tomography(OCT) in normal, preperimetric glaucoma(PPG) and perimetric glaucoma(PG) patients. METHODS: This cross-sectional observational study includes 127 eyes of 127 subjects. Patients were divided into PPG(51 eyes), PG(46 eyes), and normal controls(30 eyes) based on clinical optic disc assessment and Humphrey visual field changes. The Heidelberg Spectralis OCT machine using Glaucoma Module Premium Edition software was used to measure the retinal nerve fiber layer(RNFL) and Bruch’s membrane opening-minimum rim width(BMO-MRW) to assess the optic nerve head and ganglion cell layer(GCL) thickness in the macula. RESULTS: RNFL, MRW, and GCL thickness were all significantly thinner in PG compared to PPG and the normal group. The BMO-MRW parameters showed better specificity(>70%) at 90% specificity compared to both RNFL and GCL parameters to discriminate normal, PPG, and PG patients. All BMO-MRW parameters showed higher area under curves(AUC) compared to RNFL and GCL parameters with the highest AUC observed in the superotemporal sector of the BMO-MRW(AUC=0.819 and and 0.897 between normal and PPG and PG groups respectively).CONCLUSION: While the BMO-MRW best discriminates PPG and PG against normal eyes, GCL parameters poorly differentiate the three groups.
