There are some limitations in the current technologies for osteochondral repair and regeneration, and it is still difficult for the strategies for osteochondral tissue engineering to obtain lasting and effective outcomes. The emergence and development of three-dimensional (3D) bioprinting have provided novel and powerful technical means for the reconstruction of osteochondral tissue. The controlled deposition of bioactive materials makes it possible to accurately reconstruct the heterogeneous microstructure of osteochondral tissue. This article summarizes the latest developments in the field of osteochondral bioprinting, including scaffold-based bioprinting, scaffold-free bioprinting, and in situ bioprinting. At the same time, the major considerations of osteochondral bioprinting are discussed, and current solutions and research trends are proposed, to broaden the understanding of readers about 3D bioprinting of osteochondral tissue.Oral soft tissue engineering involves the reconstruction or restoration of oral and maxillofacial functions and esthetics. As an emerging technology from the early 21st century, three-dimensional (3D) bioprinting promises great application potentials in the preparation of scaffolds and engineered tissues/organs. Although oral soft tissues include dental pulp, periodontal ligament, gum, oral mucosa, and salivary glands as well as related maxillofacial skin, vascular, muscular, and neuronal tissues, the current application of 3D bioprinting in oral soft tissue-restoration is mainly limited to dental pulp-regeneration. Different bioinks are used to load dental pulp cells into the dentin matrix for restoring the dental pulp tissue; 3D bioprinting has only been reported in a few in vitro studies on periodontal ligament-reconstruction and salivary gland culture; and 3D bioprinting used towards regenerating gingival tissue/oral mucosa has not been demonstrated. The limited application of 3D bioprinting in oral soft tissue engineering is perhaps related to the complex, fine, and orderly structure of the periodontal ligament, the moist environment of the oral cavity, the small operating space, and the continuous chewing pressure. The studies on bioprinting of skin, vascular, muscular, and neuronal tissues are broad, but they are typically not oral-specific. This article introduces the current application status and prospects of 3D bioprinting in the regeneration of oral soft tissues, using cytocompatible hydrogels as bioinks.We present an overview of the research evidence on nurse staffing levels in acute hospitals, and how it has been applied to policy and practice, focussing primarily on the UK. Drawing on research reviews and examples of specific studies, we outline the current state of knowledge. Much of the evidence comes from cross-sectional studies. More recently, longitudinal studies allow a causal link between staffing and outcomes to be inferred. Lack of specificity on staffing levels has hindered application of research findings to practice; research rarely specifies how many nurses are needed for safe and effective care. The most significant impediment to achieving safe staffing has been an underestimation of the number of RNs needed and overestimation of the potential for substitution, resulting in low baseline staffing and a national shortage of RNs. Repeatedly, new staffing solutions are sought rather than tackle the problem of too few RNs head-on.Characterization of genomic regions underlying adaptation of landraces can reveal a quantitative genetics framework for local wheat (Triticum aestivum L.) adaptability. A collection of 512 wheat landraces from the eastern edge of the Fertile Crescent in Iran and Pakistan were genotyped using genome-wide single nucleotide polymorphism markers generated by genotyping-by-sequencing. The minor allele frequency (MAF) and the heterozygosity (H) of Pakistani wheat landraces (MAF = 0.19, H = 0.008) were slightly higher than the Iranian wheat landraces (MAF = 0.17, H = 0.005), indicating that Pakistani landraces were slightly more genetically diverse. Population structure analysis clearly separated the Pakistani landraces from Iranian landraces, which indicates two separate adaptability trajectories. The large-scale agro-climatic data of seven variables were quite dissimilar between Iran and Pakistan as revealed by the correlation coefficients. Genome-wide association study identified 91 and 58 loci using agroclimatic data, which likely underpin local adaptability of the wheat landraces from Iran and Pakistan, respectively. Selective sweep analysis identified significant hits on chromosomes 4A, 4B, 6B, 7B, 2D, and 6D, which were colocalized with the loci associated with local adaptability and with some known genes related to flowering time and grain size. RIP kinase inhibitor This study provides insight into the genetic diversity with emphasis on the genetic architecture of loci involved in adaptation to local environments, which has breeding implications.Mungbean (Vigna radiata L.), a fast-growing legume species, is an important source of carbohydrates and proteins in developing countries of Asia. Here, we constructed a near-complete genome sequence of mungbean with a scaffold N50 value of 5.2 Mb and only a 0.4% gap, with a total scaffold size of 475 Mb. We identified several misassembled pseudomolecules (Chr03, Chr04, Chr05, and Chr08) in the previous draft assembly; Chr03, Chr04, and Chr08 were assembled into one chromosome, and Chr05 was broken into two chromosomes in the improved reference genome assembly, thus providing more accurate linkage information to breeders. Additionally, using an ultra-high-resolution linkage map constructed based on resequencing data, we identified several quantitative trait loci (QTLs) and the underlying candidate genes affecting synchronous pod maturity (SPM). Mungbean homologs of two soybean ([Glycine max (L.) Merr.] flowering genes, E3 (phytochrome A) and J (early flowering 3), were identified as candidate genes for the QTLs, and the candidate genes for plant height, node number, and SPM showed critical nucleotide substitutions between the reference cultivar and other genotypes (landraces and wild accessions). Based on the analysis of genetic diversity among 276 accessions collected from 23 countries, we identified 36 selective sweep regions and observed that the overall genetic diversity of cultivars decreased to 30% of that in wild accessions postdomestication. The near-complete genome sequence of mungbean represents an important resource for genome-assisted improvement in the mungbean breeding program.
