Although electrospun poly(methyl methacrylate) (PMMA) may mimic structural features of extracellular matrix, its highly
hydrophobic nature causes reduced cell attachment. This study analysed the physicochemical and structural changes
of the surface modified PMMA nanofiber. The electrospun PMMA nanofibers (PM) were surface-treated as follows: PM
alone, collagen coated-PM (PM-C), UV-irradiated PM (PM-UV), collagen coated UV-irradiated PM (PM-C-UV) and collagen
coated-PM crosslinked with genipin (PM-C-GEN). They were subjected to scanning electron microscopy, Fourier transform
infrared (FTIR), cell attachment analysis, X-ray photoelectron spectroscopy (XPS), atomic force microscopy and X-ray
powder diffraction (XRD). The surface roughness was lower in PM-C-UV group compared to others. Based on FTIR
results, all expected functional group were present in all groups. XPS result showed that there are changes in the mass
concentration of UV-treated surfaces and in the collagen coated surfaces. All PM groups showed amorphous nature through
XRD. UV irradiation and collagen coating were shown to increase PM’s functional groups and modify its surface, which
contributed to the increased attachment of cells onto the inert PM scaffold. As conclusion, collagen coated UV irradiated
PMMA provided a better surface for cell to attach hence are suitable to be used further as scaffold for in vitro model.
Ficus carica, a native plant to the Middle East and Western Asia, is of high value in folk medicine. The therapeutic potential
of Ficus carica has led to the extensive studies in recent years, focusing on evaluating and validating its pharmacological
effect. The present systematic review summarizes the effectiveness of Ficus carica on promoting bone health focusing on
osteoporosis and rheumatoid arthritis via mineral contents and RANKL pathway. The search was done with Medline via
Ebscohost, Scopus and Google Scholar databases to obtain relevant articles published between 1946 and December
2016. The main inclusion criteria were research articles published in English that reported effect of Ficus carica on
bone health. The literature search returned 716 potentially relevant articles, whereby 5 met the inclusion criteria. This
systematic review concludes Ficus carica plays an important role in the promotion of bone health and can be a potential
pharmaceutical product in the future.
Endometriosis occurs when endometrial-like tissue forms and grows outside the uterus due to oestrogen-induced epithelial-mesenchymal transition in the female reproductive tract. Factors that suppress this event could become potential therapeutic agents against disease occurrence and progression. However, an overview of these studies is still lacking. This review assessed the impact of a number factors on oestrogen-mediated epithelial-mesenchymal transition in the emergence of several diseases in the female reproductive tract, primarily endometriosis. The association between epithelial-mesenchymal transition and Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome was also investigated. Oestrogen, Wnt4 and epithelial-mesenchymal transition were chosen as keywords in Scopus, PubMed, and Web of Science searches performed on 28th June 2021. Study selection was refined to cancer-irrelevant, English, original articles published between years 2011-2021. The full-text assessment was carried out for topic-related articles after title and abstract screening. Included studies were summarised and assessed for their risk of bias using the Office of Health Assessment and Translation tool. In this review, 10 articles investigating oestrogen and epithelial-mesenchymal transition in the female reproductive tract were summarised and classified into two groups: seven studies under 'factor'-modulated epithelial-mesenchymal transition and three studies under 'factor'-manipulated oestrogen-induced epithelial-mesenchymal transition. The current evidence proposes that epithelial-mesenchymal transition is one of the prime causes of reproductive-related disease. This event could be mediated by distinct stimuli, specifically oestrogen and Wnt4 aberration. The results of this review suggest that oestrogen and Wnt4 participate in epithelial-mesenchymal transition in vaginal epithelial cells in MRKH syndrome, adopting from the theories of endometriosis development, which could therefore serve as a foundation for novel target treatment, specifically related to vaginal epithelialisation, to ensure better surgical outcomes.
