Abstract
Advances in targeted covalent inhibitors (TCIs) have been made by using lysine-reactive chemistries. Few aminophiles possessing balanced reactivity/stability for the development of cell-active TCIs are however available. We report herein lysine-reactive activity-based probes (ABPs; 2-14) based on the chemistry of aryl fluorosulfates (ArOSO2 F) capable of global reactivity profiling of the catalytic lysine in human kinome from mammalian cells. We concurrently developed reversible covalent ABPs (15/16) by installing salicylaldehydes (SA) onto a promiscuous kinase-binding scaffold. The stability and amine reactivity of these probes exhibited a broad range of tunability. X-ray crystallography and mass spectrometry (MS) confirmed the successful covalent engagement between ArOSO2 F on 9 and the catalytic lysine of SRC kinase. Chemoproteomic studies enabled the profiling of >300 endogenous kinases, thus providing a global landscape of ligandable catalytic lysines of the kinome. By further introducing these aminophiles into VX-680 (a noncovalent inhibitor of AURKA kinase), we generated novel lysine-reactive TCIs that exhibited excellent in vitro potency and reasonable cellular activities with prolonged residence time. Our work serves as a general guide for the development of lysine-reactive ArOSO2 F-based TCIs.

Abstract
EGFR signaling is involved in multiple cellular processes including cell proliferation, differentiation and development, making this protein kinase one of the most valuable drug targets for the treatment of non-small cell lung carcinomas (NSCLC). Herein, we describe the design and synthesis of a series of potential covalent inhibitors targeting the catalytically conserved lysine (K745) of EGFR on the basis of Erlotinib, an FDA-approved first-generation EGFR drug. Different amine-reactive electrophiles were introduced at positions on the Erlotinib scaffold proximal to K745 in EGFR. The optimized compound 26 (as well as its close analog 30), possessing a novel arylfluorosulfate group (ArOSO2F), showed excellent in vitro potency (as low as 0.19 nM in independent IC50 determination) and selectivity against EGFR and many of its drug-resistant mutants. Both intact protein mass spectrometry (MS) and site-mapping analysis revealed that compound 26 covalently bound to EGFR at K745 through the formation of a sulfamate. In addition, compound 26 displayed good anti-proliferative potency against EGFR-overexpressing HCC827 cells by inhibiting endogenous EGFR autophosphorylation. The pharmacokinetic studies of compound 26 demonstrated the druggable potential of other ArOSO2F-containing compounds. Finally, competitive activity-based protein profiling (ABPP), cellular thermal shift assay (CETSA), as well as cellular wash-out experiments, all showed compound 26 to be the first cell-active, fluorosulfate-based targeted covalent inhibitor (TCI) of protein kinases capable of covalently engaging the catalytically conserved lysine of its target in live mammalian cells.

Abstract
PURPOSE/OBJECTIVE(S) Visual guidance has been widely proven to improve the reproducibility and stability of Deep Inspiration Breath Hold (DIBH) treatments. Here, we present a quality improvement project by implementing the use of visual guidance in a multi-campus institution to improve clinical efficiency, including the design of a novel mount for the visual aid and the creation of a patient education video to better prepare lung and GI patients for their DIBH treatments. MATERIALS/METHODS Prior to institution-wide implementation, the clinical feasibility of utilizing visual guidance for DIBH treatments was determined by a pilot study with 10 lung/GI patients. A commercial visual guidance device was used, which consisted of a tablet-like device, attached to a mount affixed to the treatment couch. The device is positioned over the patient's head, displaying the real-time vertical motion of a block with infrared markers on the patient's abdomen. The original mount for the device locks onto the superior end of the treatment couch, which occupies space used for immobilization devices and limits the number of patients eligible for visual guidance when the isocenter is inferior, as for GI patients. A novel in-house mount was designed to overcome this limitation. Also, a patient education video was created to introduce the concept of DIBH and the visual aid device. Visual guidance is offered at the first treatment; its use is optional, and patients may start or stop using it at any time. If the device is not used, the patient relies on audio coaching from the radiation therapists (RTTs), which is the standard practice in our clinic. RESULTS All 10 patients in the pilot who were offered the visual aid used it, found it helpful and continued to use it throughout their treatment, with no issues reported. The median number of fractions for all 10 patients was 5(3-15). The in-house mount was manufactured from 3D printed and machined components. The treatment couch was 3D scanned, and the mount was designed to clamp laterally on the couch top and align with the indexing indentations. The in-house mount is easy to use and is more versatile than the commercial mount, enabling use for patients with inferior isocenters. Prior to treatment, patients were encouraged to view the <3 min long patient education video that consisted of a combination of animation and real-actor content. Verbal instructions for use were also given by RTTs at the first treatment. Upon successful completion of the pilot study, the use of visual guidance was implemented institution-wide across 5 campuses for all lung and GI DIBH patients, being utilized on an average of 14 patients/week. CONCLUSION A quality improvement project was developed and successfully implemented to introduce the use of visual guidance for lung and GI DIBH patients at a large institution, improving the efficiency of DIBH treatment for both the patients and RTTs.

Abstract
Carbon doping in GaN-on-Silicon (Si) epitaxial layers is an essential way to reduce leakage current and improve breakdown voltage. However, complicated occupy forms caused by carbon lead to hard analysis leakage/breakdown mechanisms of GaN-on-Si epitaxial layers. In this paper, we demonstrate the space charge distribution and intensity in GaN-on-Si epitaxial layers from 0 to 448 V by simulation. Depending on further monitoring of the trapped charge density of CN and CGa in carbon-doped GaN at 0.1 μm, 0.2 μm, 1.8 μm and 1.9 μm from unintentionally doped GaN/carbon-doped GaN interface, we discuss the relationship between space charge and plateau, breakdown at CN concentrations from 6 × 1016 cm-3 to 6 × 1018 cm-3. The results show that CN in different positions of carbon-doped GaN exhibits significantly different capture and release behaviors. By utilizing the capture and release behavior differences of CN at different positions in carbon-doped GaN, the blocking effect of space charge at unintentionally doped GaN/carbon-doped GaN interface on electron conduction was demonstrated. The study would help to understand the behavior of CN and CGa in GaN-on-Si epitaxial layers and more accurate control of CN and CGa concentration at different positions in carbon-doped GaN to improve GaN-on-Si device performance.

Abstract
Although dietary fructose is associated with an elevated risk for pancreatic cancer, the underlying mechanisms remain elusive. Here, we report that ketohexokinase (KHK), the rate-limiting enzyme of fructose metabolism, is a driver of PDAC development. We demonstrate that fructose triggers KHK and induces fructolytic gene expression in mouse and human PDAC. Genetic inactivation of KhkC enhances the survival of KPC-driven PDAC even in the absence of high fructose diet. Furthermore, it decreases the viability, migratory capability, and growth of KPC cells in a cell autonomous manner. Mechanistically, we demonstrate that genetic ablation of KHKC strongly impairs the activation of KRAS-MAPK pathway and of rpS6, a downstream target of mTORC signaling. Moreover, overexpression of KHKC in KPC cells enhances the downstream KRAS pathway and cell viability. Our data provide new insights into the role of KHK in PDAC progression and imply that inhibiting KHK could have profound implications for pancreatic cancer therapy.

Abstract
The human endocannabinoid system regulates a myriad of physiological processes through a complex lipid signaling network involving cannabinoids and their respective receptors, cannabinoid receptor 1 (hCB1R) and cannabinoid receptor 2 (hCB2R). Anandamide (AEA) and cannabidiol (CBD) are classical examples of cannabinoids that elicit a variety of effects, both beneficial and detrimental, through these receptors. Mounting evidence suggested the presence of other potential cannabinoid targets that may be responsible for other observable effects. However, prior pharmacological studies on these cannabinoid compounds provided scant evidence of direct engagement to these proposed targets. Moreover, to the best of our knowledge, no chemoproteomics studies nor any protein profiling studies have been demonstrated on CBD. Here we showed that, by taking advantage of the recently developed 'label-free' 2D-TPP (2 Dimensional-Thermal Protein Profiling) approach, we have identified several new putative targets of both AEA and CBD. Comparison of these interaction landscapes with those obtained from the well-established affinity-based protein profiling (AfBPP) platforms led to the discovery of both shared and unique protein targets. Subsequent target validation studies of selected proteins led us to conclude that this 2D-TPP strategy complements well with the AfBPP approach.

Abstract
BACKGROUND Dastarcus helophoroides is an important natural enemy of cerambycids, and is wildly used in biological control of pests. Nevertheless, the absence of complete genomic information limits the investigation of the underlying molecular mechanisms. Here, a chromosome-level of Dastarcus helophoroides genome is assembled using a combination strategy of Illumina, PacBio, 10x™ Genomics, and Hi-C. RESULTS The final assembly is 609.09 Mb with contig N50, scaffold N50 and GC content of 5.46 Mb, 42.56 Mb and 31.50%, respectively, and 95.25% of the contigs anchor into 13 chromosomes. In total 14 890 protein-coding genes and 65.37% repeat sequences are predicted in the assembly genome. The phylogenetic analysis of single-copy gene families shared among 20 insect species indicates that Dastarcus helophoroides is placed as the sister species to clade (Nitidulidae+Curculionoidea+Chrysomeloidea) + Tenebrionoidea, and diverges from the related species ~242.9 Mya. In total 36 expanded gene families are identified in Dastarcus helophoroides genome, and are functionally related to drug metabolism and metabolism of xenobiotics by cytochrome P450. Some members of CYP4 Clade and CYP6 Clade are up-regulated in Dastarcus helophoroides adults upon insecticide exposure, of which expressions of DhCYP4Q, DhCYP6A14X1 and DhCYP4C1 are significantly up-regulated. The silencing of the three genes leads to adults more sensitive to insecticide and increased knocked-down rate, which may indicate their critical roles in stress resistance and detoxication. CONCLUSION Our study systematically integrated the chromosome-level genome, transcriptome and gene expression of Dastarcus helophoroides, which will provide valuable resources for understanding mechanisms of pesticide metabolism, growth and development, and utilization of the natural enemy in integrated control. © 2022 Society of Chemical Industry.

Abstract
OBJECTIVE To determine how honokiol affects the sirtuin-3 (SIRT3)-MnSOD2 pathway and oxidative stress in rats with hypertriglyceridemia-induced acute pancreatitis (HTGP). METHODS Thirty 4-week-old male SD rats were randomly divided into two groups for normal feeding and high-fat feeding for 4 weeks, after which the rats with normal feeding were randomized into control group and acute pancreatitis (AP) group (n=6), and those with high-fat feeding were divided into hypertriglyceridemia group, HTGP group, and honokiol treatment group (n=6). In AP, HTGP, and honokiol groups, AP models were established by intraperitoneal injection of cerulean; in honokiol group, the rats received an intraperitoneal injection of 5 mg/kg honokiol 15 min after cerulean injection. Serum TG, IL-6, and TNF-α levels were measured 24 h after the treatments, and pathological changes in the pancreas were observed with HE staining; The levels of reactive oxygen species (ROS), malondialdehyde (MDA), and glutathione peroxidase (GSH) were measured, and SIRT3 and manganese superoxide dismutase (MnSOD2) expressions were detected using Western blotting and immunohistochemistry. Transmission electron microscopy was used to examine the ultrastructure of pancreatic acinar cells and mitochondria. RESULTS Compared with the those with normal feeding, the rats with high-fat feeding had significantly elevated serum TG level (P < 0.05). The rat models of AP showed significantly increased serum levels of IL-6, TNF-α, and MDA and decreased GSH level and expressions of SIRT3 and MnSOD2, with obvious edema and inflammatory cell infiltration and enhanced ROS fluorescence intensity in the pancreas and ultrastructural damages of the acinar cells and mitochondria. In rats with HTGP, honokiol treatment significantly decreased serum levels of IL-6, TNF-α, and MDA, increased GSH level and SIRT3 and MnSOD2 expressions, reduced ROS production, and alleviated ultrastructural damage of the acinar cells and mitochondria in the pancreas. CONCLUSION Honokiol reduce oxidative stress and alleviates pancreatic injuries in HTGP rats possibly by activating the SIRT3-MnSOD2 pathway.

Abstract
Drugs and bioactive natural products exert their pharmacological effects by engaging numerous cellular targets in our body. Identification of these protein targets is essential for understanding the mechanism-of-action of these compounds, thus contributing to improved drug design in drug discovery programs. Termed "in situ drug profiling", a common strategy for studying these bioactive compounds centralized on the covalent capture of protein targets along with a reporter tag to facilitate downstream proteomic analyses. Though highly successful, such a strategy required innate electrophilic traps to facilitate covalent capture, and its dependence on classical alkylation/acylation strategies to install reporter tags has restricted its applications on non-covalent compounds. Late-stage C-H functionalization (LSF) may resolve this by substituting biologically inert C-H bonds with desired electrophilic groups. Herein, we demonstrated this concept by arming a diverse range of electron-rich aromatic drugs and natural products with α,β-unsaturated esters, via late-stage C-H olefination with a arylthio-based carboxylic acid ligand developed by Ibanez and co-workers. We also showed that covalent probes generated from this LSF approach could be applied for "in situ drug profiling" of ∆8-THC, as exemplified by the successful target engagement of α-4db, a ∆8-THC-based probe, to its native target hCB2R. In combination with probe 7, a photoaffinity-based derivative of ∆8-THC, we identified several novel putative targets that could account for some of the effects in THC consumption. We anticipate our C-H LSF strategy to be widely adopted for future studies of non-covalent drugs.

Abstract
Multiplex detection of protein post-translational modifications (PTMs), especially at point-of-care, is of great significance in cancer diagnosis. Herein, we report a machine learning-assisted photonic crystal hydrogel (PCH) sensor for multiplex detection of PTMs. With closely-related PCH sensors microfabricated on a single chip, our design achieved not only rapid screening of PTMs at specific protein sites by using only naked eyes/cellphone, but also the feasibility of real-time monitoring of phosphorylation reactions. By taking advantage of multiplex sensor chips and a neural network algorithm, accurate prediction of PTMs by both their types and concentrations was enabled. This approach was ultimately used to detect and differentiate up/down regulation of different phosphorylation sites within the same protein in live mammalian cells. Our developed method thus holds potential for POC identification of various PTMs in early-stage diagnosis of protein-related diseases.

Abstract
Vaccination against human cytomegalovirus (CMV) infection remains high priority. A recombinant form of a protein essential for CMV entry, glycoprotein B (gB), demonstrated partial protection in a clinical trial (NCT00299260) when delivered with the MF59 adjuvant. Although the antibody titre against gB correlated with protection poor neutralising responses against the 5 known antigenic domains (AD) of gB were evident. Here, we show that vaccination of CMV seronegative patients induces an antibody response against a region of gB we term AD-6. Responses to the polypeptide AD-6 are detected in >70% of vaccine recipients yet in <5% of naturally infected people. An AD-6 antibody binds to gB and to infected cells but not the virion directly. Consistent with this, the AD-6 antibody is non-neutralising but, instead, prevents cell-cell spread of CMV in vitro. The discovery of AD-6 responses has the potential to explain part of the protection mediated by gB vaccines against CMV following transplantation.

Abstract
Lysine-targeting irreversible covalent inhibitors have attracted growing interests in recent years, especially in the fields of kinase research. Despite encouraging progress, few chemistries are available to develop inhibitors that are exclusively lysine-targeting, selective, and cell-active. We report herein a 2-ethynylbenzaldehyde (EBA)-based, lysine-targeting strategy to generate potent and selective small-molecule inhibitors of ABL kinase by selectively targeting the conserved catalytic lysine in the enzyme. We showed the resulting compounds were cell-active, capable of covalently engaging endogenous ABL kinase in K562 cells with long-residence time and few off-targets. We further validated the generality of this strategy by developing EBA-based irreversible inhibitors against EGFR (a kinase) and Mcl-1 (a nonkinase) that covalently reacted with the catalytic and noncatalytic lysine within each target.

Abstract
Carbon impurity as point defects makes key impact on the leakage in GaN-on-Si structures. GaN-based epitaxial layers with different point defects by changing carbon-doped concentration were used to investigate the point defects behavior. It was found that leakage mechanisms correspond with space-charge-limited current models at low voltages, and after 1st kink, electron injection from silicon to GaN and PF conduction play a key role in the leakage of both point defects case with low carbon and high carbon doped. In addition, high carbon in GaN-on-Si epitaxial layers obtained lower leakage and larger breakdown voltage. The slope of logJ-Vhas two kinks and effective energy barrierEahas two peaks, 0.4247 eV at about 300 V and 0.3485 eV at about 900 V, respectively, which is related to accepted states and donor states related with carbon impurity. While the slope of logJ-Vhas one kink and effective energy barrierEahas one peak, 0.4794 eV at about 400 V of low carbon in GaN-on-Si epitaxial layers, indicating only field-induced accepted ionized makes impact on leakage. The comparative results of more donor trap density in high carbon indicate point defects related with carbon impurity play a key role in the kinks of logJ-Vslope.

Abstract
Despite recent interests in developing lysine-targeting covalent inhibitors, no general approach is available to create such compounds. We report herein a general approach to develop cell-active covalent inhibitors of protein kinases by targeting the conserved catalytic lysine residue using key SuFEx and salicylaldehyde-based imine chemistries. We validated the strategy by successfully developing (irreversible and reversible) covalent inhibitors against BCR-ABL kinase. Our lead compounds showed high levels of selectivity in biochemical assays, exhibited nanomolar potency against endogenous ABL kinase in cellular assays, and were active against most drug-resistant ABL mutations. Among them, the salicylaldehyde-containing A5 is the first-ever reversible covalent ABL inhibitor that possessed time-dependent ABL inhibition with prolonged residence time and few cellular off-targets in K562 cells. Bioinformatics further suggested the generality of our strategy against the human kinome.

Abstract
Atrijuglans hetaohei Yang (Lepidoptera: Gelechioidea) is one of the major pests that can seriously damage the walnut tree, leading to harvest loss. Sex pheromones regulate mating communication and reproduction in insects and provide targets for developing a novel pest control strategy. In this study, by transcriptomic sequencing and analysis of the female pheromone gland (PG) and male genitalia of A. hetaohei, we identified 92 putative genes, of which 7 desaturases (Dess), 8 fatty acyl reductases (FARs), 4 fatty acid synthetases (FASs), 2 aldehyde oxidases (AOXs), 4 acetyltransferases (ACTs), 1 chemosensory protein (CSP), and 2 odorant-binding proteins (OBPs) were predominantly expressed in the female PG, while 5 Dess, 11 FARs, 7 FASs, 6 AOXs, 1 ACT, and 1 CSP showed more robust expression in the male genitalia. Moreover, phylogenetic analysis revealed that 7 Dess and 1 FAR were grouped with genes involved in pheromone synthesis in other Lepidoptera species. Thus, we proposed that these candidate genes are possibly involved in the sex pheromone biosynthetic pathway in A. hetaohei. Our findings will provide a solid genetic basis for further exploring the function of the tissue-biased genes and may be useful to screen potential targets for interfering chemical communication in A. hetaohei.

Abstract
Women with adverse pregnancy outcomes later experience excess hypertension and cardiovascular disease, but how the events are linked is unknown. Examination of the placenta may provide clues to vascular impairments after delivery. Maternal vascular malperfusion lesions (MVMs) were abstracted from clinical reports, validated and characterized using clinical guidelines and severity score. A total of 492 women (170 with MVMs and 322 without MVMs) participated in a study visit 8 to 10 years after delivery to assess blood pressure, cardiometabolic factors, and sublingual microvascular features using sidestream dark field imaging. Covariates included age, race, adverse pregnancy outcomes (preeclampsia, small for gestational age, and preterm birth), and health behaviors. Women with versus without MVM had a distinct sublingual microvascular profile comprised of (1) lower microvascular density (-410 μm/mm2, P=0.015), (2) higher red blood cell filling as a marker of perfusion (2%, P=0.004), and (3) smaller perfused boundary region (-0.07 µm, P=0.025) as a measure of glycocalyx integrity, adjusted for covariates including adverse pregnancy outcomes. Women with MVM also had higher adjusted diastolic blood pressure (+2.6 mm Hg, P=0.021), total and LDL (low-density lipoprotein)-cholesterol (+11.2 mg/dL, P=0.016; +8.7 mg/dL, P=0.031). MVM associations with subsequent cardiovascular measures did not vary by type of adverse pregnancy outcome, except among women with preterm births where blood pressure was higher only among those with MVM. Results were similar when evaluated as MVM severity. A decade after delivery, women with placental vascular lesions had an adverse cardiovascular profile comprised of microvascular rarefaction, higher blood pressure and more atherogenic lipids. Placental histopathology may reveal a woman's early trajectory toward subsequent vascular disease.

Abstract
A resurging interest in targeted covalent inhibitors (TCIs) focus on compounds capable of irreversibly reacting with nucleophilic amino acids in a druggable target. p97 is an emerging protein target for cancer therapy, viral infections and neurodegenerative diseases. Extensive efforts were devoted to the development of p97 inhibitors. The most promising inhibitor of p97 was in phase 1 clinical trials, but failed due to the off-target-induced toxicity, suggesting the selective inhibitors of p97 are highly needed. We report herein a new type of TCIs (i.e., FL-18) that showed proteome-wide selectivity towards p97. Equipped with a Michael acceptor and a basic imidazole, FL-18 showed potent inhibition towards U87MG tumor cells, and in proteome-wide profiling, selectively modified endogenous p97 as confirmed by in situ fluorescence scanning, label-free quantitative proteomics and functional validations. FL-18 selectively modified cysteine residues located within the D2 ATP site of p97. This covalent labeling of cysteine residue in p97 was verified by LC‒MS/MS-based site-mapping and site-directed mutagenesis. Further structure–activity relationship (SAR) studies with FL-18 analogs were established. Collectively, FL-18 is the first known small-molecule TCI capable of covalent engagement of p97 with proteome-wide selectivity, thus providing a promising scaffold for cancer therapy.

Abstract
CRISPR-Cas12a system has been shown promising for nucleic acid diagnostics due to its rapid, portable and accurate features. However, cleavage of the amplicons and primers by the cis- and trans-activity of Cas12a hinders the attempts to integrate the amplification and detection into a single reaction. Through phosphorothioate modification of primers, we realized onepot detection with high sensitivity using plasmids of SARS-CoV-2, HPV16 and HPV18. We also identified the activated Cas12a has a much higher affinity to C nucleotide-rich reporter than others. By applying such reporters, the reaction time required for a lateral-flow readout was significantly reduced. Furthermore, to improve the specificity of the strip-based assay, we created a novel reporter and, when combined with a customized gold-nanopaticle strip, the readout was greatly enhanced owing to the elimination of the nonspecific signal. This established system, termed Targeting DNA by Cas12a-based Eye Sight Testing in an Onepot Reaction (TESTOR), was validated using clinical cervical scrape samples for human papillomaviruses (HPVs) detection. Our system represents a general approach to integrating the nucleic acid amplification and detection into a single reaction in CRISPR-Cas systems, highlighting its potential as a rapid, portable and accurate detection platform of nucleic acids.

Abstract
The "inverse drug discovery" strategy is a potent means of exploring the cellular targets of latent electrophiles not typically used in medicinal chemistry. Cyclopropenone, a powerful electrophile, is generally used in bio-orthogonal reactions mediated by triarylphosphine or in photo-triggered cycloaddition reactions. Here, we have studied, for the first time, the proteome reactivity of cyclopropenones in live cells and discovered that the cyclopropenone warhead can specifically and efficiently modify a triple-negative breast cancer driver, glutathione S-transferase pi-1 (GSTP1), by covalently binding at the catalytic active site. Further structure optimization and signaling pathway validation have led to the discovery of potent inhibitors of GSTP1.

Abstract
INTRODUCTION Abdominal aortic aneurysm (AAA) repair may be performed through open or endovascular approaches, but the factors influencing a patient's repair-type preference are not well characterized. Here we performed a qualitative analysis to better understand factors influencing patient preference within the Preference for Open Versus Endovascular Repair of AAA Trial. METHODS Open-ended responses regarding primary (n = 21) and secondary (n = 47) factors influencing patient preference underwent qualitative analysis using the constant comparative method with iterative reviews. Codes were used to generate themes and themes grouped into categories, with each step conducted via consensus agreement between three researchers. Relative prevalence of themes were compared to ascertain trends in patient preference. RESULTS Patient responses regarding both primary and secondary factors fell into four categories: Short-term concerns, long-term concerns, advice & experience, and other. Patients most frequently described short-term concerns (23) as their primary influence, with themes including post-op complications, hospitalization & recovery, and intraoperative concerns. Long-term concerns were more prevalent (20) as secondary factors, which included themes such as survival, and chronic management. The average age of patients voicing only long-term concerns as a primary factor was 11 years younger than those listing only short-term concerns. CONCLUSION Short-term concerns relating to the procedure and recovery are more often the primary factor influencing patient preference, while long term concerns play a more secondary role. Long-term concerns are more often a primary factor in younger patients. Vascular surgeons should consider this information in shared decision making to reach an optimal outcome.

Abstract
Mitochondria are key organelles that perform vital cellular functions such as those related to cell survival and death. The targeted delivery of different types of cargos to mitochondria is a well-established strategy to study mitochondrial biology and diseases. Of the various existing mitochondrion-transporting vehicles, most suffer from poor cytosolic entry, low delivery efficiency, limited cargo types, and cumbersome preparation protocols, and none was known to be universally applicable for mitochondrial delivery of different types of cargos (small molecules, proteins, and nanomaterials). Herein, two new cell-penetrating, mitochondrion-targeting ligands (named MitoLigand ) that are capable of effectively "tagging" small-molecule drugs, native proteins and nanomaterials are disclosed, as well as their corresponding chemoselective conjugation chemistry. Upon successful cellular delivery and rapid endosome escape, the released native cargos were found to be predominantly localized inside mitochondria. Finally, by successfully delivering doxorubicin, a well-known anticancer drug, to the mitochondria of HeLa cells, we showed that the released drug possessed potent cell cytotoxicity, disrupted the mitochondrial membrane potential and finally led to apoptosis. Our strategy thus paves the way for future mitochondrion-targeted therapy with a variety of biologically active agents.

Abstract
Targeted covalent inhibitors have re-emerged as validated drugs to overcome acquired resistance in cancer treatment. Herein, by using a carbonyl boronic acid (CBA) warhead, we report the structure-based design of BCR-ABL inhibitors via reversible covalent targeting of the catalytic lysine with improved potency against both wild-type and mutant ABL kinases, especially ABLT315I bearing the gatekeeper residue mutation. We show the evolutionarily conserved lysine can be targeted selectively, and the selectivity depends largely on molecular recognition of the non-covalent pharmacophore in this class of inhibitors, probably due to the moderate reactivity of the warhead. We report the first co-crystal structures of covalent inhibitor-ABL kinase domain complexes, providing insights into the interaction of this warhead with the catalytic lysine. We also employed label-free mass spectrometry to evaluate off-targets of our compounds at proteome-wide level in different mammalian cells.

Abstract
Cervical carcinoma is the second most common cancer in women worldwide with greater than 99% of the cases caused by human papillomaviruses (HPVs). Early detection of HPVs especially the high risk types (HR-HPVs) are essential to prevent the disease progression. The existing methods for HPV detection, such as qPCR are of high sensitivity and specificity, but the need for expensive machinery and well-trained personnel slow down the disease detection. The emerging Cas12a-based method presents a new technique for nucleic acid detection. However, it is time-consuming and labor-intensive when used for HPV detection, as several reactions are required in order to identify multiple HPV infections. We herein present a non-genotyping method for 13 types of HR-HPV detection in a single reaction by combining the isothermal recombinase polymerase amplification (RPA) method with CRISPR-Cas12a technology. The result could be achieved in 35 min with high sensitivity (500 copies per reaction). This assay represents great advances for the application of RPA-Cas12a system and holds a great potential to address the key challenges facing the HPV diagnostics.

Abstract
Stem canker of Zanthoxylum bungeanum is a devastating disease that seriously affects the plantation and industrial development of Z. bungeanum due to a lack of effective control measures. The objective of this study was to screen out resistant Z. bungeanum varieties and further explore their resistance mechanisms against stem canker. Results showed that the most resistant and susceptible varieties were, respectively, Doujiao (DJ) and Fengxian Dahongpao (FD). Combining transcriptomic and metabolomic analyses, we found that the genes and metabolites associated with the phenylpropanoid metabolism, especially flavonoid biosynthesis, were highly significantly enriched in DJ following pathogen infection compared with that in FD, which indicated that the flavonoid metabolism may positively dominate the resistance of Z. bungeanum. This finding was further confirmed by quantitative real-time polymerase chain reaction analysis, through which higher expression levels of core genes involved in flavonoid metabolism in resistant variety were observed. Moreover, by analyzing the differences in the flavonoid content in the stems of resistant and susceptible varieties and the antifungal activities of flavonoids extracted from Z. bungeanum stems, the conclusion that flavonoid metabolism positively regulates the resistance of Z. bungeanum was further supported. Our results not only aid in better understanding the resistance mechanisms of Z. bungeanum against stem canker but also promote the breeding and utilization of resistant varieties.

Abstract
Mythimna separata Walker (Lepidoptera: Noctuidae) is one of the major pests that can cause severe damage to grain crops. The development of low-toxicity and high-performance botanical insecticides is becoming the focus of new pesticide research to control M. separata. Tutin, a sesquiterpene lactone compound obtained from Coriaria sinica Maxim, a native Chinese poisonous plant, has antifeedant, absorption, and stomach poisoning against a variety of pests. To understand the toxic effect of tutin on M. separata larvae, we set out to determine their antifeedant, mortality, paralysis, weight change, and to examine the spreading of M. separata hemocytes under different concentrations of tutin treatment. Tissue distribution of the immune-associated gene growth-blocking peptide (GBP) and neuroglian peptide (Nrg) was detected by reverse transcription polymerase chain reaction (PCR). Furthermore, real-time quantitative PCR was carried out to determine the expression profiles of GBP and Nrg after different concentrations of tutin stimulation. Our results revealed that tutin exhibited significant antifeedant and insecticidal activities, paralysis, weight loss to M. separata. Besides, tutin significantly influenced on the morphology of hemocytes and enhanced the expression of GBP and Nrg in M. separata.

Abstract
Abstract
Introduction
Medication self-management support has been recognised as an essential element in primary health care to promote medication adherence and health outcomes for older people with chronic conditions. A patient-centred intervention empowering patients and supporting medication self-management activities could benefit older people. This pilot study tested a newly developed medication self-management intervention for improving medication adherence among older people with multimorbidity.
Method
This was a two-arm randomised controlled trial. Older people with multimorbidity were recruited from a community healthcare centre in Changsha, China. Participants were randomly allocated to either a control group receiving usual care (n = 14), or to an intervention group receiving three face-to-face medication self-management sessions and two follow-up phone calls over six weeks, targeting behavioural determinants of adherence from the Information-Motivation-Behavioural skills model (n = 14). Feasibility was assessed through recruitment and retention rates, outcome measures collection, and intervention implementation. Follow-up data were measured at six weeks after baseline using patient-reported outcomes including medication adherence, medication self-management capabilities, treatment experiences, and quality of life. Preliminary effectiveness of the intervention was explored using generalised estimating equations.
Results
Of the 72 approached participants, 28 (38.89%) were eligible for study participation. In the intervention group, 13 participants (92.86%) completed follow-up and 10 (71.42%) completed all intervention sessions. Ten participants (71.42%) in the control group completed follow-up. The intervention was found to be acceptable by participants and the intervention nurse. Comparing with the control group, participants in the intervention group showed significant improvements in medication adherence (β = 0.26, 95%CI 0.12, 0.40, P < 0.001), medication knowledge (β = 4.43, 95%CI 1.11, 7.75, P = 0.009), and perceived necessity of medications (β = −2.84, 95%CI -5.67, −0.01, P = 0.049) at follow-up.
Conclusions
The nurse-led medication self-management intervention is feasible and acceptable among older people with multimorbidity. Preliminary results showed that the intervention may improve patients’ medication knowledge and beliefs and thus lead to improved adherence.

Abstract
The recent outbreak of betacoronavirus Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), which is responsible for the Coronavirus Disease 2019 (COVID-19) global pandemic, has created great challenges in viral diagnosis. The existing methods for nucleic acid detection are of high sensitivity and specificity, but the need for complex sample manipulation and expensive machinery slow down the disease detection. Thus, there is an urgent demand to develop a rapid, inexpensive, and sensitive diagnostic test to aid point-of-care viral detection for disease monitoring. In this study, we developed a clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR associated proteins (Cas) 12a-based diagnostic method that allows the results to be visualized by the naked eye. We also introduced a rapid sample processing method, and when combined with recombinase polymerase amplification (RPA), the sample to result can be achieved in 50 minutes with high sensitivity (1-10 copies per reaction). This accurate and portable detection method holds a great potential for COVID-19 control, especially in areas where specialized equipment is not available.

Abstract
Background:Rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and syndrome(SS) are common rheumatic diseases with high incidence. Patients with those rheumatic diseases are at high risk of tuberculosis (TB) infection. However, manifestations can be atypical and easily confused with those of rheumatic disease itself. For those patients, diagnosis is usually much more difficult and further make treatment delayed. Sometimes it may lead to mistreatment. Therefore, it is important to recognize the clinical characteristics of those patients.Objectives:To explore the clinical characteristics and high risk factors of common systemic rheumatism complicated with tuberculosis infection.Methods:A total of 3,906 cases of RA, SLE, and SS common systemic rheumatism diagnosed in the People’s Hospital of Sichuan Province from January 2007 to January 2017 were collected with carefully exclusion with other infectious diseases and neoplastic disease. One hundred and five patients with TB were included as infection group, including 42 cases of RA, 41 cases of SLE, and 22 cases of SS. In the control group, 84 patients with RA, 82 patients with SLE, and 44 patients with SS were randomly selected from the corresponding rheumatoid non-infected patients hospitalized during the same period.Results:Fever was the most common symptom among 42 cases of RA, 41 cases of SLE, and 22 cases of SS with TB, accounting for 83.3%, 92.7%, and 68.2%, respectively. Cough, weight loss or fatigue was less common. For 41 cases of SLE and 22 cases of SS with TB, the proportion of pulmonary was 46.3%, 59.01%, respectively.In TB infection group, 27 cases of RA, 21 cases of SLE, and 13 cases of SS with TB had two or more chest CT findings, accounting for 59%, 57%, 62%, respectively. Lesions located in the posterior or posterior segment which TB usually affected were 9 cases(33.3%),9cases(42.9%),6cases(27.2%),respectively.The daily average dose of hormones within 1 year in TB infection group was higher than that in the control group (P<0.05). For SLE patients, lower counts of CD4+TL were found in TB infection group (P<0.05), while no such differences were found in RA and SS group.Conclusion:Patients with RA who have TB infection are mainly pulmonary TB. For SLE and SS patients, the chance of pulmonary tuberculosis and extra-pulmonary tuberculosis is similar.Symptoms of RA, SLE, SS with TB, such as fever, cough, weight loss, fatigue, are similar with the primary disease or other infection. Chest imaging is diversity. It is difficult to diagnose.Daily average dose of hormone within one year may be a common risk factor for RA, SLE and SS patients with TB. Decreased CD4+TL may also be a risk factor for SLE patients with TB.References:[1]Cantini F, Nannini C, Niccoli L, et al.

Abstract
Background:The incidence of primary Sjögren’s syndrome(pSS) is increasing gradually,and it was ranking second among connective tissue diseases(CTDs)in China.Studies recently have shown that many patients with various CTDs have sleep disturbances,which seriously degraded the patient’s quality of life.As well known, Sleep is an important physiological process to maintain human metabolism, tissue repair,and homeostasis. At present,there are relatively several studies on sleep quality in patients with Rheumatoid arthritis(RA)and Systemic lupus erythematosus(SLE),but less reports on pSS in China have been published.Therefore,it is important to explore the quality of sleep and its influencing factors in such patients.Objectives:The purpose of this study is to evaluate the quality of sleep and related factors in China Mainland patients with primary Sjögren’s syndrome(pSS),and to provide reference and theoretical basis for constructing targeted sleep interventions and improve their quality of life.Methods:A all of 103 pSS patients and 40 matched healthy controls were enrolled in a comparative study of sleep quality using the Pittsburgh Sleep Quality Index(PSQI),and demographic,clinical,and laboratory data were collected from them.The patients completed questionnaires on the European League Against Rheumatism (EULAR)SS Patient Reported Index(ESSPRI), EULAR SS Disease Activity Index (ESSDAI),Xerostomia inventory(XI)with the help of researchers,Pain and fatigue were evaluated with a 100-mm visual analogue scale(VAS).Generalized Anxiety Disorder(GAD-7) and Patient Health Questionnaire(PHQ-9) were used to assess anxiety and depression separately,and whether they have autonomic symptoms (such as sweating, palpitations.)will be asked.Results:The PSQI score and the frequency of poor sleep quality(PSQI>7) were higher in the pSS patients (11.60±5.03,71.8%)than the healthy controls(5.98±3.85,25%).Poor sleepers had a significantly higher GAD-7,PHQ-9,XI,ESSPRI,pain and fatigue VAS,and longer disease duration than good sleepers.Additionally, poor sleepers show more frequent autonomic symptoms.Sleep quality of patients with pSS was positive correlated with GAD-7,PHQ-9,XI,ESSPRI,pain and fatigueVAS scores,but no correlation with disease activity.Meanwhile,depression is a independent factor of sleep quality.Conclusion:Our study showed that the sleep disturbance seen in patients with pSS may contribute to the depression associated with this disease,Future research should investigate that whether antidepressant treatment improve sleep and directly improve quality of life.References:[1]AustadC, Kvien TK, Olsen I C.Sleep disturbance in patients with rheumatoid arthritis is related to fatigue, disease activity,and other patient-reported outcomes[J].

Abstract
Effective laboratory markers for the estimation of disease severity and predicting the clinical progression of coronavirus disease-2019 (COVID-19) is urgently needed. Laboratory tests, including blood routine, cytokine profiles and infection markers, were collected from 389 confirmed COVID-19 patients. The included patients were classified into mild (n = 168), severe (n = 169) and critical groups (n = 52). The leukocytes, neutrophils, infection biomarkers [such as C-reactive protein (CRP), procalcitonin (PCT) and ferritin] and the concentrations of cytokines [interleukin (IL)-2R, IL-6, IL-8, IL-10 and tumor necrosis factor (TNF)-α] were significantly increased, while lymphocytes were significantly decreased with increased severity of illness. The amount of IL-2R was positively correlated with the other cytokines and negatively correlated with lymphocyte number. The ratio of IL-2R to lymphocytes was found to be remarkably increased in severe and critical patients. IL-2R/lymphocytes were superior compared with other markers for the identification of COVID-19 with critical illness, not only from mild but also from severe illness. Moreover, the cytokine profiles and IL-2R/lymphocytes were significantly decreased in recovered patients, but further increased in disease-deteriorated patients, which might be correlated with the outcome of COVID-19. Lymphopenia and increased levels of cytokines were closely associated with disease severity. The IL-2R/lymphocyte was a prominent biomarker for early identification of severe COVID-19 and predicting the clinical progression of the disease.
