Open Scapulothoracic Dissociation.

Scapulothoracic dissociation is a rare and serious type of trauma caused by musculoskeletal, vascular, and brachial plexus injuries owing to lateral displacement of the scapula with a strong blunt external force. Here, we describe the treatment of an open scapulothoracic dissociation patient and summarize the findings.

Omnipotent antibacterial cotton fabrics with superhydrophobic and photothermal properties.

Due to the outbreak of global public health emergency, antibacterial fabrics such as face masks are in great demand. However, common antibacterial fabrics cannot kill bacteria in minutes and they are easy to be contaminated and lost biological activity. In this work, omnipotent antibacterial cotton fabrics with superhydrophobic and photothermal properties are developed by the combination of dopamine with copper sulfide (CuS) and silver nanoparticles on cotton fabrics, and post-modification with PDMS.

Giant cavernous aneurysms occluded by aneurysmal thrombosis, calcification, parent artery occlusion: A case report and review of literature.

Background: Patients with giant intracranial aneurysms (GIAs) are at a high risk of rupture, morbidity, and mortality even after surgical or endovascular treatment. We described a case of a spontaneously occluded GIA secondary to gradual growth of the GIA, continuously progressed aneurysmal thrombosis, complete aneurysmal calcification and complete occlusion of the parent artery-the right internal carotid artery (RICA).

Case Summary: A 72-year-old female patient complained of sudden pain in her right eye upon admission to our hospital.

A study of clinical anatomy of the safe zone for the volar approach for wrist arthroscopy.

Objective: The current study was to perform an anatomical observation of the volar approach for wrist arthroscopy and to establish the safe zone for this approach.

Methods: Eight preserved specimens and 2 fresh specimens were used to simulate the medial-to-lateral operation and to mark the volar approach. Based on anatomical measurements of the volar approach, the closest distances from the 1/2, 6R, 6U, VR, VR' and VU approaches to the adjacent important structures were established.

Porous nitrogen-doped reduced graphene oxide-supported CuO@CuO hybrid electrodes for highly sensitive enzyme-free glucose biosensor.

Constructing high-performance enzyme-free biosensors for detecting glucose is essential to preliminary diabetes diagnosis. Here, copper oxide nanoparticles (CuO@CuO NPs) were anchored in porous nitrogen-doped reduced graphene oxide (PNrGO) to construct CuO@CuO/PNrGO/GCE hybrid electrode for sensitive detection of glucose. Benefiting from the remarkable synergistic effects between the multiple high activation sites of CuO@CuO NPs and the dramatic properties of PNrGO with excellent conductivity and large surface area with many accessible pores, the hybrid electrode possesses outstanding glucose sensing performance that is far superior to those of pristine CuO@CuO electrode.

Approximation capabilities of neural networks on unbounded domains.

There is limited study in the literature on the representability of neural networks on unbounded domains. For some application areas, results in this direction provide additional value in the design of learning systems. Motivated by an old option pricing problem, we are led to the study of this subject.

A Comparative Study of Seminars Combined with Case-Based Learning versus Lecture-Based Learning for Cancer Pain Teaching in Medical Oncology Internship.

Purpose: To determine whether the teaching method of seminars combined with case-based learning (CBL) is superior to the traditional lecture-based learning (LBL) for teaching cancer pain in medical oncology internship.

Methods: Sixty medical and nursing interns in the medical oncology department of our hospital were selected between January 2019 and December 2020. Thirty students received traditional LBL instruction as the control group, and 30 students received combined seminars and CBL instruction as the observation group.

Asymmetric Supercapacitors Based on Hierarchically Nanoporous Carbon and ZnCoO From a Single Biometallic Metal-Organic Frameworks (Zn/Co-MOF).

Metal-organic framework (MOF)-derived nanoporous carbons (NPCs) and porous metal oxide nanostructures or nanocomposites have gathered considerable interest due to their potential use in supercapacitor (SCs) applications, owing to their precise control over porous architectures, pore volumes, and surface area. Bimetallic MOFs could provide rich redox reactions deriving from improved charge transfer between different metal ions, so their supercapacitor performance could be further greatly enhanced. In this study, "One-for-All" strategy is adopted to synthesize both positive and negative electrodes for hybrid asymmetric SCs (ASCs) from a single bimetallic MOF.

One-step green fabrication of hierarchically porous hollow carbon nanospheres (HCNSs) from raw biomass: Formation mechanisms and supercapacitor applications.

Hierarchical porous hollow carbon nanospheres (HCNSs) were fabricated directly from raw biomass via a one-step method, in which HCNSs were obtained by thermal treatment of raw biomass in the presence of polytetrafluoroethylene (PTFE). The HCNSs possess coupling merits of uniformly distributed hollow spherical architectures, and high specific surface area, abundant accessible/open micropores and reasonable mesopores, the HCNS-based electrodes deliver high electrochemical capacitance. The formation mechanisms of pores and hollow core-shell structures were explored thoroughly, it is found that the key to the formation of hollow core-shell structure is the onset-pyrolysis temperature difference between raw biomass and PTFE.

Insight into the Intermolecular Interaction and Free Radical Polymerizability of Methacrylates in Supercritical Carbon Dioxide.

High pressure in situ Fourier transfer infrared/near infrared technology (HP FTIR/NIR) along with theoretical calculation of density functional theory (DFT) method was employed. The solvation behaviors and the free radical homopolymerization of methyl methacrylate (MMA), methacrylate acid (MAA), trifluoromethyl methacrylate (MTFMA) and trifluoromethyl methacrylate acid (TFMAA) in scCO were systematically investigated. Interestingly, the previously proposed mechanism of intermolecular-interaction dynamically-induced solvation effect (IDISE) of monomer in scCO is expected to be well verified/corroborated in view that the predicted solubility order of the monomers in scCO via DFT calculation is ideally consistent with that observed via HP FTIR/NIR.

Pri-miR-124 rs531564 polymorphism and colorectal cancer risk.

MiR-124 functions as a tumor suppressor and plays an important role in tumorigenesis. A common polymorphism (rs531564, C>G) in the pri-miR-124 has been recently studied in connection with cancer risk. The aim of the present study was to investigate the association between pri-miR-124 rs531564 polymorphism and the risk and clinicopathological characteristics of colorectal cancer (CRC).

Complete mitochondrial genome sequence and mutations of the Glioma model inbred C57BL/6 mice strain.

In the present work we undertook the complete mitochondrial genome sequencing of an important glioma model inbred rat strain for the first time. The total length of the mitogenome was 16,308 bp. It harbored 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and 1 non-coding control region (D-loop region).

Objective: To study the major metabolites of antitumor lead compound T-OA (oleanolic acyl-3, 5, 6-trimethyl pyrazine-2-methyl ester) in rat urine, in order to preliminarily infer its metabolic mode in rats.

Method: Rat urines of the blank group, the raw material group (ligustrazine TMP and oleanolic acid OA Moore equivalent) and the T-OA group were collected and freeze-dried; Solids were extracted by ethyl acetate; And then the extracts were re-dissolved with acetonitrile. HPLC-HRMS coupling technique was adopted to find the potential mass spectrum peak under ESI(+) (see symbol) ESI(-) modes.

A 3D collagen microsphere culture system for GDNF-secreting HEK293 cells with enhanced protein productivity.

Mammalian cell culture technology has been used for decades in mass production of therapeutic proteins. However, unrestricted cell proliferation usually results in low-protein productivity. Controlled proliferation technologies such as metabolism intervention and genetic manipulation are therefore applied to enhance the productivity.
