Targeting oxidative stress with natural products: A novel strategy for esophageal cancer therapy

Esophageal cancer(ESC)is a malignant tumor that originates from the mucosal epithelium of the esophagus and is part of the digestive tract.Although the exact pathogenesis of ESC has not been fully elucidated,excessive oxidative stress is an important characteristic that leads to the development of many cancers.Abnormal expression of several proteins and transcription factors contributes to oxidative stress in ESCs,which alters the growth and proliferation of ESCs and promotes their metastasis.Natural compounds,including alkaloids,terpenes,polyphenols,and xanthine compounds,can inhibit reactive oxygen species production in ESCs.These compounds reduce oxidative stress levels and subsequently inhibit the oc-currence and progression of ESC through the regulation of targets and pathways such as the cytokine interleukins 6 and 10,superoxide dismutase,the NF-+ACY-kappa+ADs-B/MAPK pathway,and the mammalian Nrf2/ARE target pathway.Thus,targeting tumor oxidative stress has become a key focus in anti-ESC therapy.This review discusses the potential of Natural products(NPs)for treating ESCs and summarizes the application prospects of oxidative stress as a new target for ESC treatment.The findings of this review provide a reference for drug development targeting ESCs.Nonetheless,further high-quality studies will be necessary to determine the clinical efficacy of these various NPs.

Reversible Data Hiding in Encrypted Image Based on Block Classification Permutation

Recently,reversible data hiding in encrypted image(RDHEI)has attracted extensive attention,which can be used in secure cloud computing and privacy protection effectively.In this paper,a novel RDHEI scheme based on block classification and permutation is proposed.Content owner first divides original image into non-overlapping blocks and then set a threshold to classify these blocks into smooth and non-smooth blocks respectively.After block classification,content owner utilizes a specific encryption method,including stream cipher encryption and block permutation to protect image content securely.For the encrypted image,data hider embeds additional secret information in the most significant bits(MSB)of the encrypted pixels in smooth blocks and the final marked image can be obtained.At the receiver side,secret data will be extracted correctly with data-hiding key.When receiver only has encryption key,after stream cipher decryption,block scrambling decryption and MSB error prediction with threshold,decrypted image will be achieved.When data hiding key and encryption key are both obtained,receiver can find the smooth and non-smooth blocks correctly and MSB in smooth blocks will be predicted correctly,hence,receiver can recover marked image losslessly.Experimental results demonstrate that our scheme can achieve better rate-distortion performance than some of state-of-the-art schemes.

长棘海星暴发对珊瑚礁区沉积物营养盐动力学的影响研究

长棘海星暴发对珊瑚礁生态系统产生了严重危害,而水体营养盐的补充可能是导致长棘海星暴发的一个关键因素。砂质沉积物对调控珊瑚礁区的营养盐浓度和结构起着关键作用,因此本研究通过流动式反应器对长棘海星和砂质沉积物进行模拟实验,分析长棘海星排泄活动及其死亡后有机体降解对水体营养盐的影响,并探究砂质沉积物的响应。实验结果表明:(1)长棘海星排泄的溶解无机氮(DIN)和溶解无机磷(DIP)通量分别为(83.55±4.74)μmol/(ind.·h)和(2.53±0.03)μmol/(ind.·h),这些营养盐可能给长棘海星的持续暴发提供营养条件;(2)砂质沉积物对长棘海星排泄导致的营养盐浓度升高具有缓冲作用,约70.7%的DIN和91.4%的DIP被截留在沉积物中,但沉积物界面营养盐交换导致的氮磷比升高可能不利于珊瑚生长;(3)长棘海星死后的有机体降解可促使沉积物–水界面释放营养盐,结合海星暴发密度估算,其释放的营养盐可导致上覆水中DIN和DIP浓度分别升高0.32μmol/L和0.01μmol/L,这可能会促使大型藻的快速生长而妨碍珊瑚的自我修复。

Scalable spray coated high performance sulfurized electron transporter for efficient and stable perovskite solar modules

The stability issue has been acknowledged as the bottleneck in the practical application of perovskite photovoltaics,while the stabilized interface between the perovskites and charge transport layers dominates their stability performance under different stresses.Here,we developed a high-performance sulfurized zinc-titanium mixed oxide(ZTO-S)electron transport layer(ETL)to fabricate large-area efficient and long-term 85℃/85%RH stable perovskite solar modules.The scalably prepared ZTO-S using the facile spray coating method demonstrates excellent electron mobility close to that of Zn O,in addition to promoting the uniform crystallization of perovskite film across the entire module via the interaction between surface S and Pb^(2+).Furthermore,this novel coordination stabilized the interface and reduced the interfacial non-radiative recombination defects within the devices,yielding an efficient and stable performance for the modules.High efficiency of 21.73%and 17.50%was achieved for blade-coated 36 cm^(2)and 100 cm^(2)perovskite solar modules,respectively.In addition,the encapsulated module(36 cm^(2))shows an attractive humidity and heat stability(85℃/85%RH)performance with a maintained 93.5%of the initial PCE over 1000 h.

Assessment of traditional Chinese medicine pattern in a bleomycininduced pulmonary fibrosis mouse model: A pilot study

Objective:To initially explore traditional Chinese medicine patterns in a bleomycin-induced pulmonary fibrosis mouse model.Methods:Thirty-six C57BL/6 mice were divided by the random number table method(with 12 rats per group)into three groups:a blank group,a model group,and a number 2 Feibi recipe(FBR-2)group.The pulmonary fibrosis mouse model was established by intratracheal instillation of bleomycin.The FBR-2 group was treated with FBR-2 for 4 weeks.Symptoms in the mice such as mental behavior,food/water intake,body weight,body temperature,respiratory rate,and tongue image were observed.The samples were collected on the 14th day and 28th day after modeling,and lung tissues were visually assessed and microscopically evaluated by staining with hematoxylin-eosin and Masson.The expression levels of hydroxyproline,interleukin(IL)-33,IL-37,tissue plasminogen activator,and plasminogen activator inhibitor-1 were determined by enzyme-linked immunosorbent assay.Results:Mice in the model group were poor in spirit,less active,slow in response,showed reduced food/water intake,body temperature,and body weight,increased respiratory rate,and their tongue color had changed from light red to dark red.However,treatment with FBR-2 significantly improved these symptoms.Extensive inflammatory cell infiltration and collagen fiber deposition were observed in the lung tissues of the model group.Compared with the blank group,the levels of hydroxyproline,IL-33,and plasminogen activator inhibitor-1 in the model group significantly increased(all P<.05),whereas that of tissue plasminogen activator significantly decreased on the 14th day and 28th day(P=.036 and P=.005,respectively).Moreover,FBR-2 improved lung inflammation and fibrinolysis imbalance and reduced collagen fiber deposition.Conclusion:To some extent,our bleomycin-induced pulmonary fibrosis mouse model exhibited traditional Chinese medicine patterns of qi deficiency,blood stasis,and heat retention.
