| 1 | Single-Cell Microwell Platform Reveals Circulating Neural Cells as a Clinical Indicator for Patients with Blood-Brain Barrier Breakdown显示文摘Central nervous system diseases commonly occur with the destruction of the blood-brain barrier.As a primary cause of morbidity and mortality,stroke remains unpredictable and lacks cellular biomarkers that accurately quantify its occurrence and development.Here,we identify NeuN^(+)/CD45^(−)/DAPI^(+)phenotype nonblood cells in the peripheral blood of mice subjected to middle cerebral artery occlusion(MCAO)and stroke patients.Since NeuN is a specific marker of neural cells,we term these newly identified cells as circulating neural cells(CNCs).We find that the enumeration of CNCs in the blood is significantly associated with the severity of brain damage in MCAO mice(p<0:05).Meanwhile,the number of CNCs is significantly higher in stroke patients than in negative subjects(p<0:0001).These findings suggest that the amount of CNCs in circulation may serve as a clinical indicator for the real-time prognosis and progression monitor of the occurrence and development of ischemic stroke and other nervous system disease. | Yu Zhang Antony R.Warden Khan Zara Ahmad Yanlei Liu Xijun He Minqiao Zheng Xinlong Huo Xiao Zhi Yuqing Ke Hongxia Li Sijia Yan Wenqiong Su Deng Cai Xianting Ding | 2021 | Research2021，，1： | 0 |
| 2 | Therapeutic values of chick early amniotic fluid(ceAF)that facilitates wound healing via potentiating a SASP-mediated transient senescence显示文摘Inflammatory,proliferative and remodeling phases constitute a cutaneous wound healing program.Therapeutic applications and medication are available;however,they commonly are comprised of fortified preservatives that might prolong the healing process.Chick early amniotic fluids(ceAF)contain native therapeutic factors with balanced chemokines,cytokines and growth-related factors;their origins in principle dictate no existence of harmful agents that would otherwise hamper embryo development.Instead,they possess a spectrum of molecules driving expeditious mitotic divisions and possibly exerting other functions.Employing both in vitro and in vivo models,we examined ceAF's therapeutic potentials in wound healing and found intriguing involvement of transient senescence,known to be intimately intermingled with Senescence Associated Secretory Phenotypes(SASP)that function in addition to or in conjunction with ceAF to facilitate wound healing.In our cutaneous wound healing models,a low dose of ceAF exhibited the best efficacies;however,higher doses attenuated the wound healing presumably by inducing p16 expression over a threshold.Our studies thus link an INK4/ARF locus-mediated signaling cascade to cutaneous wound healing,suggesting therapeutic potentials of ceAF exerting functions likely by driving transient senescence,expediting cellular proliferation,migration,and describing a homeostatic and balanced dosage strategy in medical intervention. | Mashaal Ahmad Yandi Sun Xueyao Jia Jingjia Li Lihong Zhang Ze Yang Yindan Lin Xueyun Zhang Zara Ahmad Khan Jin Qian Yan Luo | 2022 | Genes & Diseases2022，9，5： | 0 |
| 3 | Safety evaluation of nanodiamond-doxorubicin complexes in a Naïve Beagle canine model using hematologic,histological,and urine analysis显示文摘While doxorubicin(DOX)is one of the most common chemotherapeutic drugs for treating cancer,use of DOX must be managed carefully due to dose-related toxicity.Nanodiamond(ND)drug delivery system conjugated with DOX(NDX)has been reported to enhance treatment efficacy and attenuate toxicity in murine cancer models.In addition,extensive biocompatibility studies indicate that NDs seem to be well tolerated in non-human primates.Before the clinical translation of NDX,it is necessary to verify the safety of ND in large mammals.Studies of nanomedicine drug safety for large animal are not commonly reported,and this work represents a key milestone in bridging earlier advances towards clinical assessment.Herein,NDs’safety as a drug-delivery platform was evaluated in Naïve Beagle dogs.The study is performed with DOX,ND,and NDX in a dual-gender animal model using intravenous(IV)injection and hepatic portal vein(HPV)injection methods.The dogs are monitored for their health phenotype changes in continuous 5 days.Blood and urine obtained are for clinical pathology research.The results indicate that ND drug delivery platform significantly relieves DOX toxicity for Naïve Beagle dog model.This study provides guidance for the pre-clinical safety assessment of NDX therapy at large animal level. | Liping Wang Wenqiong Su Khan Zara Ahmad Xin Wang Ting Zhang Youyi Yu Edward Kai-Hua Chow Dean Ho Xianting Ding | 2022 | Nano Research2022，15，4： | 0 |
