The production of rechargeable batteries is rapidly expanding, and there are going to be new challenges in the near future about how the potential environmental impact caused by the disposal of the large volume of the used batteries can be minimized. Herein, a novel strategy is proposed to address these concerns by applying biodegradable device technology. An eco-friendly and biodegradable sodium-ion secondary battery (SIB) is developed through extensive material screening followed by the synthesis of biodegradable electrodes and their seamless assembly with an unconventional biodegradable separator, electrolyte, and package. Each battery component decomposes in nature into non-toxic compounds or elements via hydrolysis and/or fungal degradation, with all of the biodegradation products naturally abundant and eco-friendly. Detailed biodegradation mechanisms and toxicity influence of each component on living organisms are determined. In addition, this new SIB delivers performance comparable to that of conventional non-degradable SIBs. The strategy and findings suggest a novel eco-friendly biodegradable paradigm for large-scale rechargeable battery systems.The demand for interfacing electronics in everyday life is rapidly accelerating, with an ever-growing number of applications in wearable electronics and electronic skins for robotics, prosthetics, and other purposes. find more Soft sensors that efficiently detect environmental or biological/physiological stimuli have been extensively studied due to their essential role in creating the necessary interfaces for these applications. Unfortunately, due to their natural softness, these sensors are highly sensitive to structural and mechanical damage. The integration of natural properties, such as self-healing, into these systems should improve their reliability, stability, and long-term performance. Recent studies on self-healing soft sensors for varying chemical and physical parameters are herein reviewed. In addition, contemporary studies on material design, device structure, and fabrication methods for sensing platforms are also discussed. Finally, the main challenges and future perspectives in this field are introduced, while focusing on the most promising examples and directions already reported.Microencapsulation technologies are being developed to protect transplanted islets from immune rejection, to reduce or even eliminate the need for immunosuppression. However, unencapsulated cells increase the chances of rejection and empty beads increase transplant volumes. Thus, separation processes were investigated to remove these byproducts based on density differences. The densities of islet-sized mouse insulinoma 6 (MIN6) cell aggregates and acellular 5% alginate beads generated via emulsification and internal gelation were ~ 1.065 and 1.042 g/ml, respectively. The separation of empty beads from those containing aggregates was performed by sedimentation under unit gravity in continuous gradients of polysucrose and sodium diatrizoate with density ranges of 1.032-1.045, 1.035-1.044, or 1.039-1.042 g/ml. The 1.039-1.042 g/ml gradient enabled recoveries of ~ 80% of the aggregate-containing beads while the other gradients recovered only ~ 60%. The bottom fraction of the 1.039-1.042 g/ml gradient contained beads with ~ 6% of their volume occupied by cell aggregates. Separation of unencapsulated aggregates from the aggregate-containing beads was then achieved by centrifugation of this purified fraction in a 1.055 g/ml density solution. Thus, these sedimentation-based approaches can effectively remove the byproducts of cell encapsulation.Aqueous zinc-ion batteries (ZIBs) are considered to be a promising candidate for flexible energy storage devices due to their high safety and low cost. However, the scalable assembly of flexible ZIBs is still a challenge. Here, a scalable assembly strategy is developed to fabricate flexible ZIBs with an ultrathin all-in-one structure by combining blade coating with a rolling assembly process. Such a unique all-in-one integrated structure can effectively avoid the relative displacement or detachment between neighboring components to ensure continuous and effective ion- and/or loading-transfer capacity under external deformation, resulting in excellent structural and electrochemical stability. Furthermore, the ultrathin all-in-one ZIBs can be tailored and edited controllably into desired shapes and structures, further extending their editable, stretchable, and shape-customized functions. In addition, the ultrathin all-in-one ZIBs display the ability to integrate with perovskite solar cells to achieve an energy harvesting and storage integrated system. These enlighten a broad area of flexible ZIBs to be compatible with highly flexible and wearable electronics. The scaling-up assembly strategy provides a route to design other ultrathin all-in-one energy storage devices with stretchable, editable, and customizable behaviors.Polyalkyl furans are widespread in nature, often performing important biological roles. Despite a plethora of methods for the synthesis of tetrasubstituted furans, the construction of tetraalkyl furans remains non-trivial. The prevalence of alkyl groups in bioactive furan natural products, combined with the desirable bioactivities of tetraalkyl furans, calls for a general synthetic protocol for polyalkyl furans. This paper describes a Michael-Heck approach, using sequential phosphine-palladium catalysis, for the preparation of various polyalkyl furans from readily available precursors. The versatility of this method is illustrated by the total syntheses of nine distinct polyalkylated furan natural products belonging to different classes, namely the furanoterpenes rosefuran, sesquirosefuran, and mikanifuran; the marine natural products plakorsins A, B, and D and plakorsin D methyl ester; and the furan fatty acids 3D5 and hydromumiamicin.
Polydactyly and syndactyly are the most common hereditary limb malformations. Molecular genetic testing is of great significance for hereditary limb malformations, which can establish prognosis and recurrence risk of surgical intervention.

The present study aimed to identify the genetic etiologies of a three-generation family with postaxial polydactyly and a four-generation family with postaxial syndactyly. Whole exome sequencing was used, followed by standard mutation screening procedure, Sanger sequencing and bioinformatics analysis.

Two nonframeshifting insertion/deletion (indel) mutations in HOXD13 (c.206_207ins AGCGGCGGCTGCGGCGGCGGCGGCp.A68insAAAAAAAA or c.171_182delGGCGGCGGCGGC p.56_60delAAAA) were successfully identified as the pathogenic mutation. The two nonframeshifting indel mutations led to truncation or expansion of homopolymeric alanine (Poly-Ala) repeats of HOXD13 proteins. Sequence alignment of HOXD13 protein among many different species for Poly-Ala position is highly conserved. Hypothetical three-dimensional (3-D) structural analysis further showed mutant HOXD13 proteins (p.
