This paper briefly review s the preclinical and clinical applications of PCDs based X-ray imaging systems.Starting with an introduction of X-ray single photon detection mechanism,the brief review first describes tw o major advantages of utilizing PCDs: photon energy resolving capability and electronic noise elimination. Compared to energy integrating detectors(EIDs),the aforementioned advantages make PCDs more favorable in X-ray imaging with profound benefits such as enhanced tissue contrast,decreased image noise,increased signal to noise ratio,decreased radiation dose to the small animals and patients,and more accurate material decomposition. The utilizations of PCDs in X-ray projection radiography and computed tomography(CT)including micro-CT,dedicated breast CT,K-edge CT,and clinical CT are then review ed for the imaging applications ranging from phantoms to small animals and humans. In addition,optimization methods aiming to improve the imaging performance using PCDs are briefly review ed. PCDs are not flaw less though,and their limitations are also discussed in this review. Nevertheless,PCDs may continuously contribute to the advancement of X-ray imaging techniques in future preclinical and clinical applications.展开更多

CircRNAs have long been considered to play important roles in various physiological and pathological processes as non-coding RNAs. However, circRNAs have recently garnered considerable attention due to their ability to be translated into peptides/proteins via internal ribosome entry site- or N6-methyladenosine-mediated pathways or rolling translation mechanisms. Furthermore, dysregulation of translatable circRNAs and their encoded proteins has been associated with developing and progressing diseases such as cancer. This review aims to summarize the driving mechanisms of circRNA translation and the available strategies in circRNA translation research. The main focus is on the emerging biological functions of translatable circRNAs, their regulatory mechanisms, and potential clinical applications in human diseases to provide new perspectives on disease diagnosis, prognosis, and targeted therapy.展开更多

PAI, a combination of optical illumination and ultrasound detection, allows us to achieve fine resolution and obtain fruitful information of endogenous and exogenous chromophores. Among PAI imaging techniques, photoacoustic computed tomography(PACT)has been extensively used in human studies due to its deep tissue penetration(several centimeters). Alternatively, photoacoustic microscopy(PAM) offers higher resolution at the expense of penetration depth, which can also be advantageous in clinics.Recently, there has been increasing attention and studies on PAM of human tissues. In this paper, we will review principles of PAM and its applications to human tissues, including the breast tissue, carotid atheroma tissue, eye, gastrointestinal tissue,ovarian tissue and tooth ex vivo as well as the oral cavity and dermatological tissue in vivo. The paper is closed with the outlook regarding the potential applications of PAM in clinics.展开更多

Here, we discuss the current and potential applications of CRISPR/Cas9 technology and its limitations in clinical applications, as well as ethical and legal considerations in the treatment, disease prevention or disability in somatic cells or human embryo via gene editing.

文摘Autophagy,an adaptive catabolic process,plays a cytoprotective role in enabling cellular homeostasis in the innate and adaptive immune systems.Neutrophils,the most abundant immune cells in circulation,are professional killers that orchestrate a series of events during acute inflammation.The recent literature indicates that autophagy has important roles in regulating neutrophil functions,including differentiation,degranulation,metabolism and neutrophil extracellular trap formation,that dictate neutrophil fate.It is also becoming increasingly clear that autophagy regulation is critical for neutrophils to exert their immunological activity.However,evidence regarding the systematic communication between neutrophils and autophagy is insufficient.Here,we provide an updated overview of the function of autophagy as a regulator of neutrophils and discuss its clinical relevance to provide novel insight into potentially relevant treatment strategies.

文摘Photoacoustic imaging(PAI) is an emerging technology that has been dramatically developed in the last decade. PAI, a combination of optical illumination and ultrasound detection, allows us to achieve fine resolution and obtain fruitful information of endogenous and exogenous chromophores. Among PAI imaging techniques, photoacoustic computed tomography(PACT)has been extensively used in human studies due to its deep tissue penetration(several centimeters). Alternatively, photoacoustic microscopy(PAM) offers higher resolution at the expense of penetration depth, which can also be advantageous in clinics.Recently, there has been increasing attention and studies on PAM of human tissues. In this paper, we will review principles of PAM and its applications to human tissues, including the breast tissue, carotid atheroma tissue, eye, gastrointestinal tissue,ovarian tissue and tooth ex vivo as well as the oral cavity and dermatological tissue in vivo. The paper is closed with the outlook regarding the potential applications of PAM in clinics.
文摘The purpose of this study was to investigate the clinical application of severe acute respiratory distress syndrome coronavirus-2(SARS-CoV-2)specific antibody detection and anti-SARS-CoV-2 specific monoclonal antibodies(mAbs)in the treatment of coronavirus infectious disease 2019(COVID-19).The dynamic changes of SARS-CoV-2 specific antibodies during COVID-19 were studied.Immunoglobulin M(IgM)appeared earlier and lasted for a short time,while immunoglobulin G(IgG)appeared later and lasted longer.IgM tests can be used for early diagnosis of COVID-19,and IgG tests can be used for late diagnosis of COVID-19 and identification of asymptomatic infected persons.The combination of antibody testing and nucleic acid testing,which complement each other,can improve the diagnosis rate of COVID-19.Monoclonal anti-SARS-CoV-2 specific antibodies can be used to treat hospitalized severe and critically ill patients and non-hospitalized mild to moderate COVID-19 patients.COVID-19 convalescent plasma,highly concentrated immunoglobulin,and anti-SARS-CoV-2 specific mAbs are examples of anti-SARS-CoV-2 antibody products.Due to the continuous emergence of mutated strains of the novel coronavirus,especially omicron,its immune escape ability and infectivity are enhanced,making the effects of authorized products reduced or invalid.Therefore,the optimal application of anti-SARS-CoV-2 antibody products(especially anti-SARS-CoV-2 specific mAbs)is more effective in the treatment of COVID-19 and more conducive to patient recovery.

文摘Rectal cancer(RC)is the third most commonly diagnosed cancer and has a high risk of mortality,although overall survival rates have improved.Preoperative assessments and predictions,including risk stratification,responses to therapy,long-term clinical outcomes,and gene mutation status,are crucial to guide the optimization of personalized treatment strategies.Radiomics is a novel approach that enables the evaluation of the heterogeneity and biological behavior of tumors by quantitative extraction of features from medical imaging.As these extracted features cannot be captured by visual inspection,the field holds significant promise.Recent studies have proved the rapid development of radiomics and validated its diagnostic and predictive efficacy.Nonetheless,existing radiomics research on RC is highly heterogeneous due to challenges in workflow standardization and limitations of objective cohort conditions.Here,we present a summary of existing research based on computed tomography and magnetic resonance imaging.We highlight the most salient issues in the field of radiomics and analyze the most urgent problems that require resolution.Our review provides a cutting-edge view of the use of radiomics to detect and evaluate RC,and will benefit researchers dedicated to using this state-of-the-art technology in the era of precision medicine.
