Abstract This research studied the ultimate bearing capacity of laminated bamboo lumber (LBL) unit and thereby calculated the maximum bending moment. The load-displacement chart for all specimens was obtained. Then the flexural capacity of members with and without bamboo nodes in the middle section was coMPared. The bending experiment phenomenon of LBL unit was concluded. Different failure modes of bending components were analysed and concluded. Finally, the bending behaviour of LBL units is coMPared with other bamboo and timber products. It is shown that the average ultimate load of BS members is 866.1 N, the average flexural strength is 101 MPa,… More >

Abstract Several important drugs and nutritional supplements are limited by their lack of bioavailability. Nanomaterials display unique beneficial properties that might help improve the bioavailability of drugs and nutritional supplements. Unfortunately, nanomaterials produced from synthetic polymers and metals may have similar difficulties with bioavailability and toxicity. Naturally occurring biopolymers are biodegradable and non-toxic and are adaptable to the synthesis of nanoparticles. Drugs and other substances can be encapsulated or embedded in such particles with an increase in bioavailability. The search for biodegradable nanomaterials is an active research field. This review summarizes the research on nanocrystalline cellulose, starch, lignin, and other biological… More >

Abstract The mortise-tenon joint is an important hub transmitting and distributing external loads for load-bearing components (beams, columns et al.) in the ancient-timber frame structure system. However, the conventional steel hoop reinforcement methods often insert wood screws into the timber components. When the reinforced joint rotates greatly, the anchoring failure of the screws will cause damage to the timber joint. To solve this problem, this study proposes a detachable and replaceable non-destructive flat-steel jacket reinforcement method in which horizontal flat steel is placed in the center of the joint, and the bolt is extended to the outside of the timber beam.… More >

Abstract Environmental cleaning is an important aspect of bacteria control. Ethyl cellulose microcapsules containing potassium monopersulfate (PMCM) were prepared by emulsified solvent diffusion method. The chemical structure and microstructure of the obtained PMCM was characterized by methods of Fourier transform infrared spectroscopy (FT-IR), optical microscopy, scanning electron microscopy and X-ACT energy dispersive X-ray spectroscopy. The SEM micrographs of the PMCM containing 21.6% of C, 46.8% of O, 10.7% of S and 19.4% of K was relatively smooth. Thermal stability, sustained release performance, and antimicrobial activity of PMCM were investigated. The results showed that the drug loading and encapsulation efficiency of PMCM… More >

Abstract Andrographis paniculata (A. paniculata) is a Chinese herbal medicine that clears away heat, reduces inflammation, protects the liver, and promotes choleretics. The WRKYs of A. paniculata are still not well characterized, although many WRKYs have been identified in various plant species. In the present study, 59 A. paniculata WRKY (ApWRKY) genes were identified and renamed on the basis of their respective chromosome distribution. These ApWRKYs were divided into three groups via phylogenetic analysis according to their WRKY domains and combined with WRKY of Arabidopsis. The 59 identified ApWRKY transcription factors were nonuniformity distributed on 23 chromosomes of A. paniculata. From… More >

Abstract Sweet potato is a multifunctional root crop with many essential nutrients and bioactive compounds. Due to its genetic complexity and lack of genomic resources, efficient genetic studies and cultivar development lag far behind other major crops. Simple sequence repeats (SSRs) offer an effective molecular marker technology for molecular-based breeding and for locating important loci in crop plants, but only a few have previously been developed in sweet potato. To further explore new SSR markers and accelerate their use in sweet potato genetic studies, genome-wide characterization and development of SSR markers were performed using the recently published genome of sweet potato… More >

Abstract Chemotherapy may cause cellular oxidative stress to bone marrow. Oxidative damage of bone marrow hematopoietic microenvironment is closely related to chronic myelosuppression after chemotherapeutic treatment. Angelica sinensis polysaccharides (ASP) are major effective ingredients of traditional Chinese medicine Angelica with multi-target anti-oxidative stress features. In the current study, we investigated the protective roles and mechanisms of ASP on chemotherapy-induced bone marrow stromal cell (BMSC) damage. The human bone marrow stromal cell line HS-5 cells were divided into control group, 5-FU group, 5-FU + ASP group, and 5-FU + LiCl group to investigate the mechanism of ASP to alleviate 5-FU-induced BMSC proliferation… More >

Abstract Corneal collagen crosslinking (CXL) has revolutionized the treatment of keratoconus in the past decade. In order to evaluate the 3-month effects of CXL on corneal fibroblasts, a longitudinal study at the tissue and cellular level was carried out with a total of 16 rabbits that underwent CXL, deepithelialization (DEP), or non-treatment (control) and kept for 1 to 3 months. The duration of corneal stromal remodeling after CXL was determined by examining the differentiation, apoptosis, and number changes of keratocytes in tissue sections from animals 1, 2, or 3 months post-treatment. Upon the finish of tissue remodeling, separate rabbits were used… More >

Abstract Cell migration is a finely tuned biological process that often involves epithelial-mesenchymal transition (EMT). EMT is typically characterized by the upregulation of mesenchymal markers such as Snail1. This process has been shown to be of critical importance to normal developmental processes, including neural crest migration and invasion. Interestingly, similar mechanisms are utilized in disease processes, such as tumor metastasis and migration. Notably, EMT and EMT-like processes confer tumor cells with the ability to migrate, invade, and adopt stem cell-like properties that largely account for immunosuppression and tumor recurrence. Therefore, identifying sensitive EMT markers may contribute to cancer prognosis and diagnosis… More >

Abstract Recent studies have shown that the microtubule disrupting protein Stathmin 1 (STMN1) is differentially expressed in AML patients and healthy control. The aim of this study was to explore the effects and molecular mechanism of STMN1 in AML. Here, the expression of STMN1 in peripheral blood cells (PBMCs) and bone marrow of AML patients and healthy volunteers was detected by RT-PCR and Western blot. STMN1 expression was regulated by transfected with STMN1 overexpressed plasmid or shRNA in two human leukemia cell lines K562 and HL60. Cell proliferation was examined by CCK8 and Edu staining. Annexin V and TUNEL assays were… More >
