Advanced applications of cellulose-based composites in fighting bone diseases
No full textBone diseases, such as bone defects, cartilage damage, osteomyelitis, and osteoporosis, are a primary focus area in current research. Cellulose and its derivatives, the most abundant polysaccharide on Earth, have been widely used to prepare the bio-composites for bone and cartilage tissue engineering due to their excellent bio-properties. Despite the remarkable efficacy of cellulose and its derivatives composites on bones, multiple shortcomings, such as slow degradation of the cellulose sponge and tight packaging of the bacterial cellulose nanofiber layer, result in insufficient scaffold pore size, making it difficult for cells to penetrate. Therefore, it is essential to improve the properties of cellulose and its derivatives and improve their application in treating bone diseases. This paper reviews the applications of three types of nanocellulose (cellulose nanocrystals, bacterial cellulose, and cellulose nanofibers) and their derivatives in bone tissue composites. Moreover, we review these materials for bone disease treatments, including bone defect repair, cartilage regeneration, osteomyelitis, and osteoporosis

This WG element is highly accurate with convergence two orders higher than the optimal order in an energy norm and the L 2 norm. The superconvergence is verified analytically and numerically. Furthermore, the usual stabilizer in the standard weak Galerkin formulation is no longer needed for this element.The research of Junping Wang was supported by the NSF IR/D program, while working at National Science Foundation.

Expert Consensus on Prevention and Treatment of Aging-Related Gonadal Dysfunction
Get PDFAging -related hypogonadism involves complex mechanisms in humans, predominantly relating to the decline of multiple hormones and senile gonads. Late -onset hypogonadism (LOH) and erectile dysfunction (ED) are the main manifestations in men, while premature ovarian insufficiency (POI) and menopause are the main forms in women. Anti -aging measures include lifestyle modification and resistance training, hormonal supplementation, stem cell therapy, metformin, and rapamycin. In this expert consensus, the mechanisms, efficacy, and side effects of stem cell therapy on aging gonadal function are reviewed. Furthermore, various methods of stem cell therapy, administered intravenously, intracavernously, and intra-ovarially, are exemplified in detail. More clinical trials on aging -related gonadal dysfunction are required to solidify the foundation of this topic
A Rational Function Model Based Geo-Positioning Method for Satellite Images without Using Ground Control Points
No full textEarth observation satellites with various spatial, spectral and temporal resolutions provide an invaluable means for mapping and monitoring the Earth’s environments. With the increasing demand of satellite images for remote and harsh environments and nature disaster areas such as earthquake, flooding, bushfires and other emergent events, quickly geo-positioning those images without using ground control points (GCPs) is much preferable and desirable. Built on the previously developed Spatial Triangulated Network (STN) concept by the first author, this paper presents a Rational Function Model (RFM) based geo-positioning method utilizing some pre-orientated image(s) as reference, instead of using GCPs. The experimental results indicate that the RFM method is more sensitive to the base-height ratio in the vertical accuracy than the physical model based geo-positioning method which was also developed by the first author. Compared to the traditional RFM based block adjustment using GCPs, the proposed RFM based method without GCP (using orientated images instead) can achieve similar accuracies when more than one orientated image, which have reasonable strong geometric relationships with the new images, are introduced into the proposed RFM based method. The proposed method is applicable to the scenarios in which geo-positioning is required for those new satellite images that only have RFM and no GCPs available, but where there exists some orientated images covering the same region
