Cold atmospheric plasma (CAP) has attracted increasing attention due to its anti-bacterial and anti-tumor effects. Melanoma is an aggressive malignancy with increasing incidence rate and poor prognosis. Evaluating cell viability, apoptosis rate and reactive species injection efficiency of melanoma cells and human keratinocyte cells (HaCaT) treated with CAP to analyze biological safety of CAP. RNA-sequencing (RNA-seq) of A875 cells before and after treatment was performed to further explore the anti-tumor mechanism of CAP. CAP had a more significant biological effect on melanoma cells than HaCaT cells by inhibiting proliferation and promoting apoptosis. RNA-sequencing analysis showed that besides MAPK and p53 apoptotic signaling pathways, necroptosis and autophagy also played important roles in CAP-induced melanoma cells death. CAP can selectively kill melanoma cells and has good biosafety cytologically. Besides apoptosis, CAP can induce cell death via autophagy and necroptosis.The reconstituted motility system of actin-myosin is expected to be used in bioinspired transport devices, in which carried materials are attached to either moving actin filaments or walking myosin molecules. However, the dependence of the ability to transport on the size of the attached materials is still inadequately understood. Here, as carried materials, polyethylene glycols (PEGs) of various sizes are covalently bound to actin filaments, and the motility of PEG-attached filaments on a heavy meromyosin (HMM) immobilized on a glass surface is observed via fluorescence microscopy. Full attachment of 2 kDa PEG, with an approximately 2 nm gyration radius, decreases the velocity and fraction of moving actin filaments by approximately 10% relative to unattached filaments. For the 5 kDa PEG, the fraction of moving filaments is decreased by approximately 70% even when the filaments contain only 20% PEG-attached actin. The attachment of both sizes of PEGs suppresses the actin-activated ATPase activity at the same level. These results suggest that actin filaments can carry PEGs up to 2 kDa having the same size as actin monomers, while the rate of ATP hydrolysis is limited. The size dependence may provide a criterion for material delivery via actin filaments in nanotransport applications.
To describe the experience of utilization of real time indocyanide green (ICG) fluorescent imaging for mapping out drainage lymph node and hence personalized lymphadenectomy in colorectal resection.

Perioperative injection of ICG before or during colon cancer resection by either intraluminal submucosal injection or laparoscopic peritumoural injection. The drainage lymph nodes were mapped out, and hence lymphadenectomy was performed enbloc with the main tumor. The effectiveness of mapping of drainage lymphatics and the procedure performed were recorded.

A total of 21 patients (MF=14 7) had perioperative ICG injection to map out the drainage lymphatics. The overall success rate was 86%. Seven patients (33%) had endoscopic submucosal injection, while 14 patients (67%) had intraoperative peritumoural injection. Three patients who had endoscopic submucosal injection had ICG extravasation, and hence failed lymph node mapping. Four patients (19%) had a change in extent of resection according to the lymph node mapping results.

Personalized oncological colorectal resection and lymphadenectomy can be performed with the aid of ICG technology. Laparoscopic subserosal ICG injection may be the preferred route, as it minimize extravasation and aids to identify drainage lymph nodes without prolonging minimally invasive surgery. Further studies are required to determine the best route, strength, and timing of ICG injection and concordance with pathology to tailor the extent of resection for individual patients.

Polycaprolactone (PCL) has been extensively utilized for bone tissue engineering but limited cellular interaction and tissue integration are the primary concerns. PCL-based composites with different biomaterials have been attempted to improve the mechanical and biological response. Interestingly, a few studies have tried to blend PCL with aqueous silk fibroin solution, but the structures prepared with the blend were mechanically weak due to phase mismatch. As a result, silk microparticle-based PCL composites have been prepared, but the microfibers-reinforced composites could be superior to them due to significant fiber-matrix interaction. This study aims at developing a unique composite by incorporating 100-150 μm long (aspect ratio; 81-51) silk-fibroin microfibers into the PCL matrix for superior biological and mechanical properties. Two silk variants were used, that is, Bombyx mori and a wild variant, Antheraea mylitta, reported to have cell recognizable Arginine-Glycine-Aspartic acid (RGD) sequences. A. mylitta silk fibroin microfibers were produced, and composites were made with PCL for the first time. The morphological, tensile, thermal, biodegradation, and biological properties of the composites were evaluated. Importantly, we tried to optimize the silk concentration within the composite to strike a balance among the cellular response, biodegradation, and mechanical strength of the composites. The results indicate that the PCL-silk fibroin microfiber composite could be an efficient biomaterial for bone tissue engineering.Bariatric, metabolic or weight loss surgery produces sustained weight loss and imporovement in obesity related diseases. Bariatric surgery has existed for decades but there is limited reliable data on the risk of perioperative mortality following the procedures. This commentary focuses on a recent meta-analysis which has produced contemporaneous mortality data, and the findings are significant. Utilising data from 3.6 million patients the study has shown an overall pooled perioperative mortality of 0.08%, a significantly reduced risk compared to previous, smaller studies. This finding increases our knowledge of surgical risk for these procedures and should now equip health care groups to challenge barriers to uptake of bariatric surgery. Barriers currently include a worldwide lack of focus on treating obesity, lack of funding and resource from commissioners, and a general public and professional view that bariatric surgery may be high risk. In reality, this figure equates to mortality risk for procedures generally considered 'safe' such as laparoscopic cholecystectomy and knee arthroplasty. Bariatric surgery is a safe option for achieving sustained weight-loss and the treatment of obesity related diseases, and refusing access to surgery on the grounds of perioperative safety should now be an outdated premise.CRISPR/Cas system has become one of the most powerful techologies in biomedical research, and has showed great potentials in the gene related diseases. However, efficient delivery systems of CRISPR/Cas to target cells remains challenging. In recent years, nanoparticles have showned great potentials for the delivery of CRISPR/Cas systems. This paper mainly approaches the development and new strategies of CRISPR/Cas delivery systems, as well as their application in the clinical diseases. By summarizing the CRISPR/Cas systems delivery, new strategies are expected for the gene therapy.
Cam morphology contributes to the development of hip osteoarthritis (OA) but is less studied in the general population. This study describes its associations with clinical and imaging features of hip OA.

Anteroposterior hip radiographs of 1019 participants from the Tasmanian Older Adult Cohort (TASOAC) were scored at baseline for α angle (cam morphology) in both hips. find more Using the Altman's atlas, radiographic hip OA (ROA) was assessed at baseline. Hip pain and right hip structural changes were assessed on a subset of 245 magnetic resonance images (MRI) at 5years. Joint registry data for total hip replacement (THR) was acquired 14years from baseline.

Of 1906 images, cam morphology was assessed in 1016 right and 890 left hips. Cross-sectionally, cam morphology modestly associated with age (prevalence ratio [PR] 1.02 P=.03) and body mass index (BMI) (PR 1.03-1.07, P=.03) and strongly related to male gender (PR 2.96, P<.001). Radiographically, cam morphology was prevalent in those with decreased joint spaceaphic OA such as joint space narrowing (JSN) and osteophytes (OST). At follow-up, cam predicted development of hip BMLs, hip effusion-synovitis, cartilage damage and THR. These findings suggest that cam morphology plays a significant role in early OA and can be a precursor or contribute to hip OA in later life.Vacancy engineering can modulate the electronic structure of the material and thus contribute to the formation of coordination unsaturated sites, which makes it easier to act on the substrate. Herein, Ag2 S and Ag2 S-100, which mainly have vacancy associates VAgS and VAgSAg , respectively, are prepared and characterized by positron annihilation spectroscopy. Both experimental and theoretical calculation results indicate that Ag2 S-100 exhibits excellent antibacterial activity due to its appropriate bandgap and stronger bacteria-binding ability, which endow it with a superior antibacterial activity compared to Ag2 S in the absence of light. The in vivo antibacterial experiment using a mouse wound-infection model further confirms that Ag2 S-100 has excellent antibacterial and wound-healing properties. This research provides clues for a deeper understanding of modulating electronic structures through vacancy engineering and develops a strategy for effective treatment of bacterial infections.
Virtual simulation is an interactive teaching and learning strategy used in undergraduate nursing student education, especially since the onset of the COVID-19 pandemic. Few published studies have reviewed the impact of virtual simulation as a strategy for teaching nursing students the elements of evidence-based practice.

To describe types of virtual simulation that are relevant to nursing student education and examine how these modalities are applied to teach elements of evidence-based practice.

A rapid review of literature was conducted to discern the use and impact of virtual simulation. Thirty-seven studies published between 2017 and May 2021 that addressed nursing students' educational outcomes were reviewed and summarized as a narrative analysis.

Virtual simulation and virtual reality simulation engage learners in role-plays via a computer screen or hand-held phone. Various levels of realism and immersion were apparent across different modalities and with the utilization of educational games. Most studies related to the teaching of best practice evidence-based clinical nursing topics.
