Abstract
Key Clinical Message Parry-Romberg syndrome is characterized by progressive dystrophy in one half of the face, which usually begins in childhood. Correct and timely diagnosis of this disease, as well as a multidisciplinary approach and timely surgical treatment to minimize the psychological effects and improve the patient's appearance are of particular importance. Abstract Parry-Romberg syndrome is characterized by progressive dystrophy or loss of subcutaneous tissue in one half of the face, which usually begins in childhood and continues with skin changes, and can also be associated with linear scleroderma. Although this disease has been known for more than 150 years, its exact cause and pathogenesis are not well understood. The clinical feature of Parry-Romberg syndrome that makes it possible to diagnose is unilateral idiopathic facial atrophy. The reported case is a 14-year-old boy who suffered from hemifacial atrophy of the frontal area since he was 7 years old was referred to a plastic and cosmetic surgery specialist and underwent surgery without systemic symptoms and in the inactive phase of the disease. Correct and timely diagnosis of this disease, as well as a multidisciplinary approach and timely and appropriate surgical treatment to minimize the psychological effects and improve the patient's appearance are of particular importance.

Abstract
BACKGROUND With Iran facing an epidemic in substance use disorders, nursing students are increasingly encountering people impacted by substance misuse. Providing care for this group brings with it many barriers and challenges. These serious barriers have not been a priority in Iranian nurse education. OBJECTIVES To describe barriers to providing quality care for people with substance use disorders from the perspective of nursing students. DESIGN A descriptive qualitative study, using content analysis was used to address the study aim. SETTING AND PARTICIPANTS Purposive sampling was used to recruit participants. Participants were 34 baccalaureate nursing students from different academic semesters studying at two medical sciences universities in Iran. METHODS Data were collected using semi-structured interviews from July 2022 to October 2022. Granheim & Lundman's method for qualitative content analysis was used to analyze data. RESULTS The barriers to providing quality care for people with substance use disorders were described through the major theme: "lack of communication skills and difficulty finding language for therapeutic communication with people with substance use disorders". Based on nursing student perspectives, a lack of communication and language for therapeutic communication was described through the three barriers of: 1. "possessing or witnessing prejudiced attitudes and stereotypes", 2 "negative role models", and 3. "Knowledge deficit in self or others". CONCLUSION The result of this study showed that nursing students interact with people with substance use disorders through prejudiced attitudes, negative stereotypes, and knowledge deficits. Academic education should include practical techniques to reduce negative stereotypes and moral distress among nursing students as well as strategies to manage tough ethical situations and decrease prejudiced attitudes. Nurses and clinical educators must be attentive to their power to influence nursing students and should model appropriate unbiased behavior and language.

Abstract
The CRISPR genome editing technology is a crucial tool for enabling revolutionary advancements in plant genetic improvement. This review shows the latest developments in CRISPR/Cas9 genome editing system variants, discussing their benefits and limitations for plant improvement. While this technology presents immense opportunities for plant breeding, it also raises serious biosafety concerns that require careful consideration, including potential off-target effects and the unintended transfer of modified genes to other organisms. This paper highlights strategies to mitigate biosafety risks and explores innovative plant gene editing detection methods. Our review investigates the international biosafety guidelines for gene-edited crops, analyzing their broad implications for agricultural and biotechnology research and advancement. We hope to provide illuminating and refined perspectives for industry practitioners and policymakers by evaluating CRISPR genome enhancement in plants.

Abstract
OBJECTIVES The aim of this study was to explore the process of how nurses experienced and dealt with alarm fatigue in intensive care units based on Iranian nurses' perceptions and experiences. BACKGROUND Alarm fatigue is the overstimulation of senses due to the constant ringing of alarms in intensive care units. It is associated with nurses' desensitization to critical alarms that can directly influence patient safety and quality of care. METHODS A qualitative exploratory study using the grounded theory approach by Strauss and Corbin was carried out. Participants were 20 nurses working in intensive care units. The sampling process was started purposively and continued theoretically. Data were collected using semi-structured, in-depth, and individual interviews and continued to data saturation. The constant comparative analysis approach was used consisting of the following steps: open coding, developing concepts, analysing the context, entering the process into data analysis, integrating categories. FINDINGS The participants' main concern in the exposure to alarm fatigue was 'threat to personal balance'. The core category in this research was 'trying to create a holistic balance', which reflected a set of strategies that the nurses consistently and continuously used to deal with alarm fatigue and consisted of four main categories as follows: 'smart care', 'deliberate balancing', 'conditional prioritisation', and 'negligent performance'. Threat to personal balance was strengthened by 'inappropriate circuit of individual roles', 'distortion of the organisational structure', and 'insecurity of the infrastructure'. The consequences of this process was harm to the patient, burnout among nurse, and damage to the healthcare organisation. CONCLUSIONS The research findings have practical implications for healthcare management, policymaking, nursing education, research, and clinical practice. Mitigating staff shortages, improving staff competencies, enhancing nurses' authority for responding to alarms, modifying care routines, improving the physical environment, and removing problems related to alarm equipment can prevent alarm fatigue and its unappropriated consequences.

Abstract
Achillea is a crop with Chinese herbal characteristics and horticultural values. Its leaves and flowers contain aromatic oil, and the ripe herb can also be used as medicine to induce sweat and relieve rheumatic pains. It is seen cultivated in gardens all over China. Currently, the most comprehensive chloroplast genome sample involved in the study refers to New World clades of Achillea, which are used for marker selection and phylogenetic research. We completely sequenced the chloroplast genomes of Achillea millefolium. These sequencing results showed that the plastid genome is 149,078 bp in size and possesses a typical quadripartite structure containing one large single copy (LSC) with 82,352 bp, one small single copy (SSC) with 18,426 bp, and a pair of inverted repeat (IR) regions with 24,150 bp in Achillea millefolium. The chloroplast genome encodes a common number of genes, of which 88 are protein-coding genes, 37 transfer ribonucleic acid genes, and 8 ribosomal ribonucleic acid genes, which are highly similar in overall size, genome structure, gene content, and sequence. The exact similarity was observed when compared to other Asteraceae species. However, there were structural differences due to the restriction or extension of the inverted repeat (IR) regions-the palindromic repeats being the most prevalent form. Based on 12 whole-plastomes, 3 hypervariable regions (rpoB, rbcL, and petL-trnP-UGG) were discovered, which could be used as potential molecular markers.

Abstract
The analysis of infrastructure use data in relation to other components of the infrastructure can help better understand the interrelationships between infrastructures to eventually enhance their sustainability and resilience. In this study, we focus on electricity consumption and travel demand. In short, the premise is that when people are in buildings consuming electricity, they are not generating traffic on roads, and vice versa, hence the presence of interrelationships. We use Long Short Term Memory (LSTM) networks to model electricity consumption patterns of zip codes based on the traffic volume of the same zip code and nearby zip codes. For this, we merge two datasets for November 2017 in Chicago: (1) aggregated electricity use data in 30-min intervals within the city of Chicago and (2) traffic volume data captured on the Chicago expressway network. Four analyses are conducted to identify interrelationships: (a) correlation between two time series, (b) temporal relationships, (c) spatial relationships, and (d) prediction of electricity consumption based on the total traffic volume. Overall, from over 250 models, we identify and discuss complex interrelationships between travel demand and electricity consumption. We also analyze and discuss how and why model performance varies across Chicago.

Abstract
Plant non-specific lipid transfer proteins (nsLTPs) are small and have a broad biological function involved in reproductive development and abiotic stress resistance. Although a small part of plant nsLTPs have been identified, these proteins have not been characterized in poplar at the genomic level. A genome-wide characterization and expression identification of poplar nsLTP members were performed in this study. A total of 42 poplar nsLTP genes were identified from the poplar genome. A comprehensive analysis of poplar nsLTPs was conducted by a phylogenetic tree, duplication events, gene structures, and conserved motifs. The cis-elements of poplar nsLTPs were predicted to respond to light, hormone, and abiotic stress. Many transcription factors (TFs) were identified to interact with poplar nsLTP cis-elements. The tested poplar nsLTPs were expressed in leaves, stems, and roots, but their expression levels differed among tested tissues. Most poplar nsLTP expression levels were changed by abiotic stress, implying that poplar nsLTP may be involved in abiotic stress resistance. Network analysis showed that poplar nsLTPs are putative genes involved in fatty acid (FA) metabolism. This research provides sight into the further study to explain the regulatory mechanism of the poplar nsLTPs.

Abstract
A comparative investigation was conducted to evaluate transcriptional changes in guard cells (GCs) of closely related halophytic (Chenopodium quinoa) and glycophytic (Spinacia oleracea) species. Plants were exposed to 3 weeks of 250 mM sodium chloride treatment, and GC-enriched epidermal fragments were mechanically prepared. In both species, salt-responsive genes were mainly related to categories of protein metabolism, secondary metabolites, signal transduction and transport systems. Genes related to abscisic acid (ABA) signaling and ABA biosynthesis were strongly induced in quinoa but not in spinach GCs. Also, expression of the genes encoding transporters of amino acids, proline, sugars, sucrose and potassium increased in quinoa GCs under salinity stress. Analysis of cell-wall-related genes suggests that genes involved in lignin synthesis (e.g. lignin biosynthesis LACCASE 4) were highly upregulated by salt in spinach GCs. In contrast, transcripts related to cell wall plasticity Pectin methylesterase3 (PME3) were highly induced in quinoa. Faster stomatal response to light and dark measured by observing kinetics of changes in stomatal conductance in quinoa might be associated with higher plasticity of the cell wall regulated by PME3 Furthermore, genes involved in the inhibition of stomatal development and differentiation were highly expressed by salt in quinoa, but not in spinach. These changes correlated with reduced stomatal density and index in quinoa, thus improving its water use efficiency. The fine modulation of transporters, cell wall modification and controlling stomatal development in GCs of quinoa may have resulted in high K+/Na+ ratio, lower stomatal conductance and higher stomatal speed for better adaptation to salinity stress in quinoa.

Abstract
BACKGROUND Alarm fatigue is a condition in which a person experiences sensory overload or desensitization in exposure to frequent non-actionable alarms. Nurses are the main users of alarms in health care and their behaviors for alarm management influence the occurrence of alarm fatigue. OBJECTIVES This qualitative research aimed to explore strategies used by nurses in dealing with nurses' alarm fatigue in the intensive care unit (ICU). DESIGN Qualitative research was carried out. Eighteen nurses working in ICUs were selected purposefully and were invited to take part in individual semi-structured interviews. Collected data were analyzed using content analysis for developing categories and subcategories. SETTING Twelve ICUs in ten hospitals in four urban areas of Iran. RESULTS The research's main category was "smart care" consisting of two categories of "technologic actions" and "non-technologic actions." Also, six subcategories were developed: "identifying the cause and taking timely actions", "personalized alarm settings", "reducing the number of unnecessary alarms", "effective teamwork", "improving the physical environment and ward arrangement", and "self-calmness". CONCLUSION Smart care by nurses included a set of active and proactive interventions developed through thinking and reflection and the use of information, skills, and experiences in order to manage exposure to alarm fatigue. Strategies used by nurses to prevent alarm fatigue can reduce the physical and psychological burden caused by frequent exposure to alarms in the ICU and consequently can have direct impacts on the quality and safety of nursing care. CLINICAL RELEVANCE Nurses in the healthcare process often experience alarm fatigue that is influenced by the cultural-contextual aspect of care and the care environment. Smart care in terms of technologic and non-technologic actions helps with the prevention of alarm fatigue.

Abstract
Background CRISPR has been increasingly used for plant genetic improvements because of its high efficiency and precision. Recently, the authors have reported the possibility of homology-directed repair (HDR) using CRISPR/Cas9 through woody plants such as poplar. HDR often replaces nucleotides with one donor DNA template (DDT), including homologous sequences. Methods CRISPR-Cas9 was recruited, and three variables, Agrobacteria inoculator concentration, pDDT/pgRNA ratio, and homologous arm length, were designed to integrate nptII and 2XCamV 35S into the MKK2 promoter zone. Results Here, we showed that recovered poplars on kanamycin-supplemented media exhibited enhanced expression of MKK2 affected by the precise integration of 2XcamV 35S and nptII, improving biochemical and phenotypic properties. Our findings confirmed that Agrobacterium inoculator OD600 = 2.5, increased DDT numbers during cell division to 4:1 pDDT/pgRNA, and optimized homologous arms 700 bp caused efficient HDR and increased MKK2 expression. Conclusion Efficient transformations resulted from optimized variables, directly affecting the HDR efficiency through woody plants such as poplar.

Abstract
Background The sucrose non-fermenting 1 (SNF1)-related protein kinases (SnRKs) play a vivid role in regulating plant metabolism and stress response, providing a pathway for regulation between metabolism and stress signals. Conducting identification and stress response studies on SnRKs in plants contributes to the development of strategies for tree species that are more tolerant to stress conditions. Results In the present study, a total of 30 LcSnRKs were identified in Liriodendron chinense (L. chinense) genome, which was distributed across 15 chromosomes and 4 scaffolds. It could be divided into three subfamilies: SnRK1, SnRK2, and SnRK3 based on phylogenetic analysis and domain types. The LcSnRK of the three subfamilies shared the same Ser/Thr kinase structure in gene structure and motif composition, while the functional domains, except for the kinase domain, showed significant differences. A total of 13 collinear gene pairs were detected in L. chinense and Arabidopsis thaliana (A. thaliana), and 18 pairs were detected in L. chinense and rice, suggesting that the LcSnRK family genes may be evolutionarily more closely related to rice. Cis-regulation element analysis showed that LcSnRKs were LTR and TC-rich, which could respond to different environmental stresses. Furthermore, the expression patterns of LcSnRKs are different at different times under low-temperature stress. LcSnRK1s expression tended to be down-regulated under low-temperature stress. The expression of LcSnRK2s tended to be up-regulated under low-temperature stress. The expression trend of LcSnRK3s under low-temperature stress was mainly up-or down-regulated. Conclusion The results of this study will provide valuable information for the functional identification of the LcSnRK gene in the future.

Abstract
Fatty acid desaturases (FADs) modulate carbon–carbon single bonds to form carbon–carbon double bonds in acyl chains, leading to unsaturated fatty acids (UFAs) that have vital roles in plant growth and development and their response to environmental stresses. In this study, a total of 23 Populus trichocarpaFAD (PtFAD) candidates were identified from the poplar genome and clustered into seven clades, including FAB2, FAD2, FAD3/7/8, FAD5, FAD6, DSD, and SLD. The exon–intron compositions and conserved motifs of the PtFADs, clustered into the same clade, were considerably conserved. It was found that segmental duplication events are predominantly attributable to the PtFAD gene family expansion. Several hormone- and stress-responsive elements in the PtFAD promoters implied that the expression of the PtFAD members was complicatedly regulated. A gene expression pattern analysis revealed that some PtFAD mRNA levels were significantly induced by abiotic stress. An interaction proteins and gene ontology (GO) analysis indicated that the PtFADs are closely associated with the UFAs biosynthesis. In addition, the UFA contents in poplars were significantly changed under drought and salt stresses, especially the ratio of linoleic and linolenic acids. The integration of the PtFAD expression patterns and UFA contents showed that the abiotic stress-induced PtFAD3/7/8 members mediating the conversion of linoleic and linolenic acids play vital roles in response to osmotic stress. This study highlights the profiles and functions of the PtFADs and identifies some valuable genes for forest improvements.

Abstract
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH), an essential enzyme of the glycolysis metabolic pathway, plays a vital role in carbon metabolism, plant development, and stress resistance. As a kind of woody plant, poplars are widely cultivated for afforestation. Although the whole genome data of poplars have been published, little information is known about the GAPDH family of genes in poplar. This study performed a genome-wide identification of the poplar GAPDH family, and 13 determined PtGAPDH genes were identified from poplar genome. Phylogenetic tree showed that the PtGAPDH members were divided into PtGAPA/B, PtGAPC, PtGAPCp, and PtGAPN groups. A total of 13 PtGAPDH genes were distributed on eight chromosomes, 13 gene pairs belonging to segmented replication events were detected in poplar, and 23 collinearity gene pairs were determined between poplar and willow. The PtGAPDHcis-acting elements associated with growth and development as well as stress resistance revealed that PtGAPDHs might be involved in these processes. The phosphoglycerate kinase (PGK) and triose-phosphate isomerase (TPI) were predicted as the putative interaction proteins of PtGAPDHs. Gene ontology (GO) analysis showed that PtGAPDHs play a crucial role in the oxidation and reduction processes. PtGAPDH expression levels were induced by NaCl and PEG treatments, which implied that PtGAPDHs might be involved in stress response. Overexpression of PtGAPC1 significantly changed the contents of lipid and carbohydrate metabolites, which indicated that PtGAPC1 plays an essential role in metabolic regulation. This study highlights the characterizations and profiles of PtGAPDHs and reveals that PtGAPC1 is involved in the loop of lipid and carbohydrate metabolisms.

Abstract
Long-chain acyl-CoA synthetases (LACSs) catalyze fatty acids (FAs) to form fatty acyl-CoA thioesters, which play essential roles in FA and lipid metabolisms and cuticle wax biosynthesis. Although LACSs from Arabidopsis have been intensively studied, the characterization and function of LACSs from poplar are unexplored. Here, 10 poplar PtLACS genes were identified from the poplar genome and distributed to eight chromosomes. A phylogenetic tree indicated that PtLACSs are sorted into six clades. Collinearity analysis and duplication events demonstrated that PtLACSs expand through segmental replication events and experience purifying selective pressure during the evolutionary process. Expression patterns revealed that PtLACSs have divergent expression changes in response to abiotic stress. Interaction proteins and GO analysis could enhance the understanding of putative interactions among protein and gene regulatory networks related to FA and lipid metabolisms. Cluster networks and long-chain FA (LCFA) and very long-chain FA (VLCFA) content analysis revealed the possible regulatory mechanism in response to drought and salt stresses in poplar. The present study provides valuable information for the functional identification of PtLACSs in response to abiotic stress metabolism in poplar.

Abstract
Cold stress limits plant geographical distribution and influences plant growth, development, and yields. Plants as sessile organisms have evolved complex biochemical and physiological mechanisms to adapt to cold stress. These mechanisms are regulated by a series of transcription factors and proteins for efficient cold stress acclimation. It has been established that the ICE-CBF-COR signaling pathway in plants regulates how plants acclimatize to cold stress. Cold stress is perceived by receptor proteins, triggering signal transduction, and Inducer of CBF Expression (ICE) genes are activated and regulated, consequently upregulating the transcription and expression of the C-repeat Binding Factor (CBF) genes. The CBF protein binds to the C-repeat/Dehydration Responsive Element (CRT/DRE), a homeopathic element of the Cold Regulated genes (COR gene) promoter, activating their transcription. Transcriptional regulations and post-translational modifications regulate and modify these entities at different response levels by altering their expression or activities in the signaling cascade. These activities then lead to efficient cold stress tolerance. This paper contains a concise summary of the ICE-CBF-COR pathway elucidating on the cross interconnections with other repressors, inhibitors, and activators to induce cold stress acclimation in plants.

Abstract
Plant non-specific lipid transfer proteins (nsLTPs) are involved in various physiological processes. However, the characteristics and function of LTPs in Populus trichocarpa are unclear. Here, we report the functional properties of type IV, V, and VI P. trichocarpa nsLTPs (PtLTPs). The IV, V, and VI PtLTPs clustered in the same clade shared similar gene structures and motif and distributions. Also, collinearity analysis revealed 2 and 7 gene pairs have tandem duplication and segmental duplication events, respectively. The expression patterns of type IV, V, and VI PtLTPs differed among poplar tissues. We investigated the effects of various stresses on the Potri.010G100600, Potri.010G196300, and Potri.016G104300 (type V LTPs) mRNA levels, and type V LTPs can respond to multiple stresses. Potri.008G061800 was localized to the cell wall, extracellular space, and plasma membrane. Glutathione-S-transferase-Potri.008G061800 obtained by prokaryotic expression had weakly inhibited the growth of Septotis populiperda in vitro. Taken together, our data show that type IV, V, and VI PtLTPs may be thought as novel regulators of plant stresses. They could be considered an effective genetic resource for molecular breeding in poplar.

Abstract
BACKGROUND Experimental and clinical studies have revealed that curcumin may be an effective therapy for non-alcoholic fatty liver disease (NAFLD). Hence, the aim of this study was to assess the effect of curcumin plus piperine administration on NAFLD. METHODS Adults 18-65 years-old diagnosed with NAFLD by liver sonography were randomly allocated to curcumin (500 mg/day) or placebo groups for 2 months. All participants received both dietary and exercise advice. Anthropometric and biochemical measurements as well as hepatic ultrasound were performed at baseline and final conditions. RESULTS Seventy-nine participants were recruited and randomly allocated into the curcumin (n = 39) or placebo (n = 40) groups. There were no significant differences between placebo and curcumin groups for demographic and clinical characteristics and NAFLD grade at baseline. After the treatment period, the curcumin group exhibited lower alkaline phosphatase (-16.2 ± 22.8 versus -6.0 ± 22.5 mg/dL, p = 0.04) concentrations and severity of NAFLD compared with the placebo group (p = 0.04). CONCLUSION Results of this clinical trial suggest that short-term treatment with curcumin plus piperine administration improves NAFLD severity.

Abstract
Poplar is an illustrious industrial woody plant with rapid growth, providing a range of materials, and having simple post-treatment. Various kinds of environmental stresses limit its output. Plant annexin (ANN) is a calcium-dependent phospholipid-binding protein involved in plant metabolism, growth and development, and cooperatively regulating drought resistance, salt tolerance, and various stress responses. However, the features of the PtANN gene family and different stress responses remain unknown in poplar. This study identified 12 PtANN genes in the P. trichocarpa whole-genome and PtANNs divided into three subfamilies based on the phylogenetic tree. The PtANNs clustered into the same clade shared similar gene structures and conserved motifs. The 12 PtANN genes were located in ten chromosomes, and segmental duplication events were illustrated as the main duplication method. Additionally, the PtANN4 homogenous with AtANN1 was detected localized in the cytoplasm and plasma membrane. In addition, expression levels of PtANNs were induced by multiple abiotic stresses, which indicated that PtANNs could widely participate in response to abiotic stress. These results revealed the molecular evolution of PtANNs and their profiles in response to abiotic stress.

Abstract
It is critical to develop plant isoprenoid production when dealing with human-demanded industries such as flavoring, aroma, pigment, pharmaceuticals, and biomass used for biofuels. The methylerythritol phosphate (MEP) and mevalonic acid (MVA) plant pathways contribute to the dynamic production of isoprenoid compounds. Still, the cross-talk between MVA and MEP in isoprenoid biosynthesis is not quite recognized. Regarding the rate-limiting steps in the MEP pathway through catalyzing 1-deoxy-D-xylulose5-phosphate synthase and 1-deoxy-D-xylulose5-phosphate reductoisomerase (DXR) and also the rate-limiting step in the MVA pathway through catalyzing 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR), the characterization and function of HMGR from Populus trichocarpa (PtHMGR) were analyzed. The results indicated that PtHMGR overexpressors (OEs) displayed various MEP and MVA-related gene expressions compared to NT poplars. The overexpression of PtDXR upregulated MEP-related genes and downregulated MVA-related genes. The overexpression of PtDXR and PtHMGR affected the isoprenoid production involved in both MVA and MEP pathways. Here, results illustrated that the PtHMGR and PtDXR play significant roles in regulating MEP and MVA-related genes and derived isoprenoids. This study clarifies cross-talk between MVA and MEP pathways. It demonstrates the key functions of HMGR and DXR in this cross-talk, which significantly contribute to regulate isoprenoid biosynthesis in poplars.

Abstract
CRISPR-mediated genome editing has become a powerful tool for the genetic modification of biological traits. However, developing an efficient, site-specific, gene knock-in system based on homology-directed DNA repair (HDR) remains a significant challenge in plants, especially in woody species like poplar. Here, we show that simultaneous inhibition of non-homologous end joining (NHEJ) recombination cofactor XRCC4 and overexpression of HDR enhancer factors CtIP and MRE11 can improve HDR efficiency for gene knock-in. Using this approach, the BleoR gene was integrated onto the 3' end of the MKK2 MAP kinase gene to generate a BleoR-MKK2 fusion protein. Based on fully edited nucleotides evaluated by TaqMan real-time PCR, the HDR-mediated knock-in efficiency was up to 48% when using XRCC4 silencing incorporated with a combination of CtIP and MRE11 overexpression compared with no HDR enhancement or NHEJ silencing. Furthermore, this combination of HDR enhancer overexpression and NHEJ repression also increased genome targeting efficiency and gave 7-fold fewer CRISPR-induced insertions and deletions (InDels), resulting in no functional effects on MKK2-based salt stress responses in poplar. Therefore, this approach may be useful not only in poplar and plants or crops but also in mammals for improving CRISPR-mediated gene knock-in efficiency.

Abstract
One of the strategies to reduce the off-target mutations in CRISPR/Cas9 system is to use the temperature-independent gene transformation method. Mesoporous silica nanoparticles (MSNs)-gene delivery system is temperature-independent; thus, it can transfer the interesting plasmid (pDNA) to the target plant at different temperatures, including 37 °C. Due to the high activity of SpCas9 at 37 °C compared to lower temperatures, on-target mutagenesis increases at 37 °C. Therefore, we describe the synthesis of the functionalized MSNs with the particle size of less than 40 nm, binding pDNA to the MSNs, and transferring of the pDNA-MSNs into the target plants.

Abstract
Coronary artery bypass grafting (CABG) surgery with two methods (on-pump or off-pump) can be used to rescue individuals with severe coronary artery disease (CAD). Each method might cause an inflammatory response, which can lead to some complications. The aim of this study was to compare the changes in serum concentrations of IFN-γ, tumor necrosis factor (TNF)-α, interleukin (IL)-1α, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, VEGF, MCP-1, and epidermal growth factor between the two CABG surgery methods. Forty-eight patients (22 = on-pump, 26 = off-pump) who underwent on-pump or off-pump CABG surgery were enrolled in this study. Serum cytokines levels were measured in two blood samples, the first sample was taken from each patient in the morning of the day of surgery after a 12-hr fasting and the second sample on the first postoperative day at 24-hr after surgery. In baseline, comparisons between the two groups of on-pump/off-pump surgery did not show any significant difference in demographic data, anthropometric parameters, lipid profile indices, and high-sensitivity C-reactive protein levels (p > .05). There was a significant difference between the serum levels of IL-4, IL-6, IL-10, vascular endothelial growth factor (VEGF), IFN-γ, and MCP-1 in patients with on-pump surgery and a significant increase in serum IL-6 (p < .001), IL8 (p < .05), VEGF (p < .001), and IFN-γ (p < .01) levels in patients with off-pump surgery in post-operation stage compared to pre-operation. Cardiopulmonary pump in patients under CABG surgery can activate systemic inflammation and the changes of serum cytokines levels in off-pump CABG were lower compared with on-pump CABG.

Abstract
Populus trees meet continuous difficulties from the environment through their life cycle. To warrant their durability and generation, Populus trees exhibit various types of defenses, including the production of secondary metabolites. Syntheses derived from the shikimate-phenylpropanoid pathway are a varied and plentiful class of secondary metabolites manufactured in Populus. Amongst other main classes of secondary metabolites in Populus are fatty acid and terpenoid-derivatives. Many of the secondary metabolites made by Populus trees have been functionally described. Any others have been associated with particular ecological or biological processes, such as resistance against pests and microbial pathogens or acclimatization to abiotic stresses. Still, the functions of many Populus secondary metabolites are incompletely understood. Furthermore, many secondary metabolites have therapeutic effects, leading to more studies of secondary metabolites and their biosynthesis. This paper reviews the biosynthetic pathways and therapeutic impacts of secondary metabolites in Populus using a genomics approach. Compared with bacteria, fewer known pathways produce secondary metabolites in Populus despite P. trichocarpa having had its genome sequenced.

Abstract
Despite the huge contribution of membrane-based brine and wastewater purification systems in today's life, biofouling still affects sustainability of membrane engineering. Aimed at reducing membrane modules wastage, the need to study biofouling monitoring as one of contributory factors stemmed from the short time between initial attachment and irreversible biofoulant adhesion. Hence, a membrane for monitoring is introduced to determine the right cleaning time by using fluorescent sensing as a non-destructive and scalable approach. The classical solid-state emissive fluorophore, tetraphenylethylene (TPE), was introduced as a sustainable, safe and sensitive fluorescent indicator in order to show the potential of the method, and polyethersulfone (PES) and nonsolvent-induced phase separation method, the most popular material and method, are used to fabricate membrane in industry and academia. Since the employed filler has an aggregation-induced emission (AIE) characteristic, it can track the biofouling throughout the operation. The fabricated membranes have certain characterizations (i.e. morphology assessment, flux, antibiogram, flow cytometry, surface free energy, and protein adsorption) which indicate that hybrid membrane with 5 wt % of TPE has identical biofouling activity compared to neat PES membrane and its optimal luminescence properties make it an appropriate candidate for non-destructive and online biofouling monitoring.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a global health problem with increasing prevalence among overweight and obese patients. It is strongly associated with conditions of insulin resistance including type 2 diabetes mellitus (T2DM) and obesity. It has detrimental consequences ranged from simple steatosis to irreversible hepatic fibrosis and cirrhosis. Curcumin is a dietary polyphenol with potential effect in improving NAFLD. Therefore, the aim of this trial was to examine the effect of curcumin supplementation on various aspects of NAFLD. In this trial, a total number of 80 patients were randomised to receive either curcumin at 250 mg daily or placebo for 2 months. Lipid profiles, hepatic enzymes, anthropometric indices and hepatic fat mass were assessed at the baseline and the end of the trial, and compared within the groups. The grade of hepatic steatosis, and serum aspartate aminotransferase (AST) levels were significantly reduced in the curcumin group (p = 0.015 and p = 0.007, respectively) compared to the placebo. There was also a significant reduction in high density lipoprotein (HDL) levels and anthropometric indices in both groups with no significant differences between the two groups. Low dose phospholipid curcumin supplementation each day for 2 months showed significant reduction in hepatic steatosis and enzymes in patients with NAFLD compared to placebo. Further studies of longer duration and higher dosages are needed to assess its effect on other parameters of NAFLD including cardiovascular risk.

Abstract
Backgrounds Fatty acid desaturases (FADs) introduce a double bond into the fatty acids acyl chain resulting in unsaturated fatty acids that have essential roles in plant development and response to biotic and abiotic stresses. Wheat germ oil, one of the important by-products of wheat, can be a good alternative for edible oils with clinical advantages due to the high amount of unsaturated fatty acids. Therefore, we performed a genome-wide analysis of the wheat FAD gene family (TaFADs). Results 68 FAD genes were identified from the wheat genome. Based on the phylogenetic analysis, wheat FADs clustered into five subfamilies, including FAB2, FAD2/FAD6, FAD4, DES/SLD, and FAD3/FAD7/FAD8. The TaFADs were distributed on chromosomes 2A-7B with 0 to 10 introns. The Ka/Ks ratio was less than one for most of the duplicated pair genes revealed that the function of the genes had been maintained during the evolution. Several cis-acting elements related to hormones and stresses in the TaFADs promoters indicated the role of these genes in plant development and responses to environmental stresses. Likewise, 72 SSRs and 91 miRNAs in 36 and 47 TaFADs have been identified. According to RNA-seq data analysis, the highest expression in all developmental stages and tissues was related to TaFAB2.5, TaFAB2.12, TaFAB2.15, TaFAB2.17, TaFAB2.20, TaFAD2.1, TaFAD2.6, and TaFAD2.8 genes while the highest expression in response to temperature stress was related to TaFAD2.6, TaFAD2.8, TaFAB2.15, TaFAB2.17, and TaFAB2.20. Furthermore, docking simulations revealed several residues in the active site of TaFAD2.6 and TaFAD2.8 in close contact with the docked oleic acid that could be useful in future site-directed mutagenesis studies to increase the catalytic efficiency of them and subsequently improve agronomic quality and tolerance of wheat against environmental stresses. Conclusions This study provides comprehensive information that can lead to the detection of candidate genes for wheat genetic modification.

Abstract
BACKGROUND AND AIMS Soil salinization and aridification are swiftly engulfing the limited land resources on which humans depend, restricting agricultural production. Hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) is important in the biosynthesis of terpenoids, which are involved in plant growth, development and responses to environmental stresses. This study aimed to provide guidance for producing salt- and drought-resistant poplar. METHODS A protein expression system was used to obtain PtHMGR protein, and high-performance liquid chromatography was used to detect the activity of PtHMGR protein in vitro. In addition, a simplified version of the leaf infection method was used for transformation of 'Nanlin895' poplar (Populus×euramericana). qRT-PCR was used to identify expression levels of genes. KEY RESULTS PtHMGR catalysed a reaction involving HMG-CoA and NADPH to form mevalonate. Overexpression of PtHMGR in Populus × euramericana 'Nanlin895' improved drought and salinity tolerance. In the presence of NaCl and PEG6000, the rates of rooting and survival of PtHMGR-overexpressing poplars were higher than those of wild-type poplars. The transgenic lines also exhibited higher proline content and peroxidase and superoxide dismutase activities, and a lower malondialdehyde level under osmotic stress. In addition, the expression of genes related to reactive oxygen species (ROS) scavenging and formation was altered by osmotic stress. Moreover, the effect of osmotic stress on transcript levels of stress-related genes differed between the transgenic and wild-type poplars. CONCLUSION PtHMGR catalysed a reaction involving HMG-CoA and NADPH to form mevalonate in vitro. Overexpression of PtHMGR promoted root development, increased the expression of ROS scavenging-related genes, decreased the expression of ROS formation-related genes, and increased the activity of antioxidant enzymes in transgenic poplars, enhancing their tolerance of osmotic stress. In addition, overexpression of PtHMGR increased expression of the stress-related genes KIN1, COR15 and AAO3 and decreased that of ABI, MYB, MYC2 and RD22, enhancing the stress resistance of poplar.

Abstract
Detecting traffic accidents as rapidly as possible is essential for traffic safety. In this study, we use eXtreme Gradient Boosting (XGBoost)-a Machine Learning (ML) technique-to detect the occurrence of accidents using a set of real time data comprised of traffic, network, demographic, land use, and weather features. The data used from the Chicago metropolitan expressways was collected between December 2016 and December 2017, and it includes 244 traffic accidents and 6073 non-accident cases. In addition, SHAP (SHapley Additive exPlanation) is employed to interpret the results and analyze the importance of individual features. The results show that XGBoost can detect accidents robustly with an accuracy, detection rate, and a false alarm rate of 99 %, 79 %, and 0.16 %, respectively. Several traffic related features, especially difference of speed between 5 min before and 5 min after an accident, are found to have relatively more impact on the occurrence of accidents. Furthermore, a feature dependency analysis is conducted for three pairs of features. First, average daily traffic and speed after accidents/non-accidents time at the upstream location are interpreted jointly. Then, distance to Central Business District and residential density are analyzed. Finally, speed after accidents/non-accidents time at upstream location and speed after accidents/non-accidents time at downstream location are evaluated with respect to the model's output.

Abstract
Plant defensins have been implicated in the plant defense system, but their role in poplar immunity is still unclear. In the present study, we present evidence that PtDefensin, a putative plant defensin, participates in the defense of poplar plants against Septotis populiperda infection. After the construction of recombinant plasmid PET-32a-PtDefensin, PtDefensin protein was expressed in Escherichia coli strain BL21 (DE3) and purified through Ni-IDA resin affinity chromatography. The Trx-PtDefensin fusion protein displayed no cytotoxic activity against RAW264.7 cells but had cytotoxic activity against E. coli K12D31 cells. Analyses of PtDefensin transcript abundance showed that the expression levels of PtDefensin responded to abiotic and biotic stresses. Overexpression of PtDefensin in 'Nanlin 895' poplars (Populus × euramericana cv 'Nanlin895') increased resistance to Septotis populiperda, coupled with upregulation of MYC2 (basic helix-loop-helix (bHLH) transcription factor) related to jasmonic acid (JA) signal transduction pathways and downregulation of Jasmonate-zim domain (JAZ), an inhibitor in the JA signal transduction pathway. We speculate that systemic acquired resistance (SAR) was activated in non-transgenic poplars after S. populiperda incubation, and that induced systemic resistance (ISR) was activated more obviously in transgenic poplars after S. populiperda incubation. Hence, overexpression of PtDefensin may improve the resistance of poplar plants to pathogens.

Abstract
Cellulose, the most abundant constituent material of the plant cell walls, is a major structural component of plant biomass. Manipulating cellulose synthesis (CesA) genes by genetic engineering technology, to increase cellulose production may thus offer novel opportunities for plant growth and development. To investigate this, here we produced transgenic "Populus 895 plants" overexpressing the cellulose synthase (CesA2) gene derived from Pinus massoniana under the control of constitutive 35S promoter, via Agrobacterium-mediated transformation. Relative expression levels of PmCesA2 were functionally characterized in poplar hybrid clone "Nanlin895" (Populus deltoides × Populus euramericana). The results demonstrated the transgenic lines showed enhanced growth performance with increased biomass production than did the untransformed controls. It is noteworthy that the overexpression of PmCesA2 in poplar led to an altered cell wall polysaccharide composition, which resulted in the thickening of the secondary cell wall and xylem width under scanning electron microscopy. Consequently, the cellulose and lignin content were increased. Hence, this study suggests that overexpression of PmCesA2 could be used as a potential candidate gene to enhance cellulose synthesis and biomass accumulation in genetically engineered trees.

Abstract
PtDef cloned from Populus trichocarpa contained eight cysteine domains specific to defensins. Quantitative reverse-transcription polymerase chain reaction (qRT-PCR) analysis showed that PtDef was expressed in all tissues tested, with lower expression in leaves and higher expression in petioles, stems, and roots. Purified fused PtDef inhibited Aspergillus niger, Alternaria Nees, Mucor corymbifer, Marssonina populi, Rhizopus sp., and Neurospora crassa. PtDef also inhibited the growth of Escherichia coli by triggering autolysis. PtDef overexpression in Nanlin895 poplar (Populus × euramericana cv. Nanlin895) enhanced the level of resistance to Septotinia populiperda. qRT-PCR analysis also showed that the expression of 13 genes related to salicylic acid (SA) and jasmonic acid (JA) signal transduction differed between transgenic and wild-type (WT) poplars before and after inoculation, and that PR1-1 (12–72 h), NPR1-2, TGA1, and MYC2-1 expression was higher in transgenic poplars than in WT. During the hypersensitivity response (HR), large amounts of H2O2 were produced by the poplar lines, particularly 12–24 h after inoculation; the rate and magnitude of the H2O2 concentration increase were greater in transgenic lines than in WT. Overall, our findings suggest that PtDef, a defensin-encoding gene of P. trichocarpa, could be used for genetic engineering of woody plants for enhanced disease resistance.

Abstract
The venom of animals, including snakes, scorpions, and spiders is a complex combination of proteins, peptides, and other biomolecules as well as some minerals. Among the biomolecules of some animal&rsquo;s venom, small peptides that lack disulfide bands known as Non-Disulfide Bridge Peptides (NDBPs) potentiate the bradykinin by preventing the conversion of angiotensin 1 to angiotensin 2 using the mechanism of inhibiting the Angiotensin-Converting Enzyme activity and finally reducing the blood pressure in the victims. This feature of the NDBPs of animal&rsquo;s venom is suggested as the potential of biological drugs. This study aimed to isolate venom components of three species of Iranian medically important scorpions and study the bradykinin potentiating effect of them. The scorpion specimens were collected from the venomous animals and antivenom production department of Razi Vaccine and Serum Research Institute, Karaj, Iran. Moreover, venom extraction was performed by electrical shock (5 volts). The obtained liquid venom of three species specimens was frozen and lyophilized immediately and then preserved in a cool and dried place. The isolation of the venom components for each scorpion was carried out using high-performance liquid chromatography. The obtained ranges of venom fractions (zones) were tested on isolated tissues of guinea-pig ileum and rat uterus using organ bath instrumentation in several replicates. The bioassays resulted in the peptides, including Z1 and Z2 regions in the venom fractionsof the Hottentotta saulcyi, Z2 in Odontobuthus doriae, as well as Z2 and Z3 in Mesobuthus eupeus demonstrated bradykinin potentiating effect. It is concluded that Bradykinin Potentiating Factors were traceable in the venom of all three scorpion species. Therefore, these venoms have the therapeutic potential to exploit biological-based drugs.

Abstract
Interferon gamma-induced lysosomal thiol reductase (GILT) is abundantly expressed in antigen-presenting cells and participates in the treatment and presentation of antigens by major histocompatibility complex II. Also, GILT catalyzes the reduction of disulfide bonds, which plays an important role in cellular immunity. (1) Background: At present, the studies of GILT have mainly focused on animals. In plants, GILT homologous gene (Arabidopsis thalianaOSH1: AtOSH1) was discovered in the forward screen of mutants with compromised responses to sulphur nutrition. However, the complete properties and functions of poplar OSH1 are unclear. In addition, CdCl2 stress is swiftly engulfing the limited land resources on which humans depend, restricting agricultural production. (2) Methods: A prokaryotic expression system was used to produce recombinant PtOSH1 protein, and Western blotting was performed to identify its activity. In addition, a simplified version of the floral-dip method was used to transform A. thaliana. (3) Results: Here, we describe the identification and characterization of OSH1 from Populus trichocarpa. The deduced PtOSH1 sequence contained CQHGX2ECX2NX4C and CXXC motifs. The transcript level of PtOSH1 was increased by cadmium (Cd) treatment. In addition, recombinant PtOSH1 reduced disulfide bonds. A stress assay showed that PtOSH1-overexpressing (OE) A. thaliana lines had greater resistance to Cd than wild-type (WT) plants. Also, the activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) in PtOSH1-OE plants were significantly higher than those in WT A. thaliana. These results indicate that PtOSH1 likely plays an important role in the response to Cd by regulating the reactive oxygen species (ROS)-scavenging system. (4) Conclusions: PtOSH1 catalyzes the reduction of disulfide bonds and behaves as a sulfhydryl reductase under acidic conditions. The overexpression of PtOSH1 in A. thaliana promoted root development, fresh weight, and dry weight; upregulated the expression levels of ROS scavenging-related genes; and improved the activity of antioxidant enzymes, enhancing plant tolerance to cadmium (Cd) stress. This study aimed to provide guidance that will facilitate future studies of the function of PtOSH1 in the response of plants to Cd stress.

Abstract
We aimed to compare the concentrations of serum cytokines in patients undergoing coronary angiography and finding their possible associations with metabolic syndrome. Twelve serum cytokines and growth factors (IL-1α, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-α, MCP-1, IFN-γ, EGF, and VEGF) were measured by sandwich chemiluminescence assays, on the Evidence Investigator® system. There were significant differences regarding sex, height, weight, BMI, WC, HC, FPG, TG and HDL-C between those with and without MetS in patients undergoing angiography (p < .05). Serum concentrations of IL-6 and INF-γ were significantly higher in subjects with MetS, compared to those without MetS (p = .031 and p = .035, respectively). However, only serum IL-6 was associated with the presence of MetS (β = 1.215, CI = 1.047-1.409, p = .010). From several serum cytokines and growth factors assessed in patients, IL-6 was the only serum cytokine that was significantly different between those with and without MetS after correction for confounding factors.

Abstract
In the mevalonic acid (MVA) pathway, 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) is considered the first rate-limiting enzyme in isoprenoid biosynthesis. In this study, we cloned a full-length cDNA from Populus trichocarpa with an open reading frame of 1,734 bp. The deduced PtHMGR sequence contained two HMG-CoA motifs and two NADPH motifs, which exhibited homology with HMGR proteins from other species. Subsequently, truncated PtHMGR was expressed in Escherichia coli BL21 (DE3) cells, and enzyme activity analysis revealed that the truncated PtHMGR protein could catalyze the reaction of HMG-CoA and NADPH to form MVA. Relative expression analysis suggests that PtHMGR expression varies among tissues and that PtHMGR responds significantly to abscisic acid (ABA), NaCl, PEG6000, hydrogen peroxide (H2O2), and cold stresses. We used polymerase chain reaction (PCR) analysis to select transgenic Nanlin 895 poplars (Populus× euramericana cv.) and quantitative reverse-transcription PCR (qRT-PCR) to show that PtHMGR expression levels were 3- to 10-fold higher in transgenic lines than in wild-type (WT) poplars. qRT-PCR was also used to determine transcript levels of methylerythritol phosphate (MEP)-, MVA-, and downstream-related genes, indicating that overexpression of PtHMGR not only affects expression levels of MVA-related genes, but also those of MEP-related genes. We also measured the content of terpenoids including ABA, gibberellic acid (GA), carotenes, and lycopene. PtHMGR overexpression significantly increased ABA, GA, carotene, and lycopene content, indicating that PtHMGR participates in the regulation of terpenoid compound synthesis.

Abstract
1-Deoxy-D-xylulose-5-phosphate synthasse (DXS) and 1-deoxy-D-xylulose-5-phosphate reductoisomerase (DXR) are key enzymes in terpenoid biosynthesis. DXS catalyzes the formation of 1-deoxy-D-xylulose 5-phosphate (DXP) from pyruvate and D-glyceraldehyde-3-phosphate. DXR catalyzes the formation of 2-C-methyl-D-erythritol 4-phosphate (MEP) from DXP. Previous studies of the DXS and DXR genes have focused on herbs, such as Arabidopsis thaliana, Salvia miltiorrhiza, and Amomum villosum, but few studies have been conducted on woody plants. For that reason, we chose Populus trichocarpa as a model woody plant for investigating the DXS and DXR genes. PtDXS exhibited the highest expression level in leaves and the lowest expression in roots. PtDXR showed maximum expression in young leaves, and the lowest expression in mature leaves. The expression profiles revealed by RT-PCR following different elicitor treatments such as abscisic acid, NaCl, PEG6000, H2O2, and cold stress showed that PtDXS and PtDXR were elicitor-responsive genes. Our results showed that the PtDXS gene exhibited diurnal changes, but PtDXR did not. Moreover, overexpression of PtDXR in transgenic poplars improved tolerance to abiotic and biotic stresses. Those results showed that the PtDXR encoded a functional protein, and widely participates in plant growth and development, stress physiological process.

Abstract
The CRISPR/Cas9 system (clustered regularly interspaced short palindromic repeat-associated protein 9) is a powerful genome-editing tool in animals, plants, and humans. This system has some advantages, such as a high on-target mutation rate (targeting efficiency), less cost, simplicity, and high-efficiency multiplex loci editing, over conventional genome editing tools, including meganucleases, transcription activator-like effector nucleases (TALENs), and zinc finger nucleases (ZFNs). One of the crucial shortcomings of this system is unwanted mutations at off-target sites. We summarize and discuss different approaches, such as dCas9 and Cas9 paired nickase, to decrease the off-target effects in plants. According to studies, the most effective method to reduce unintended mutations is the use of ligand-dependent ribozymes called aptazymes. The single guide RNA (sgRNA)/ligand-dependent aptazyme strategy has helped researchers avoid unwanted mutations in human cells and can be used in plants as an alternative method to dramatically decrease the frequency of off-target mutations. We hope our concept provides a new, simple, and fast gene transformation and genome-editing approach, with advantages including reduced time and energy consumption, the avoidance of unwanted mutations, increased frequency of on-target changes, and no need for external forces or expensive equipment.

Abstract
1-Deoxy-d-xylulose-5-phosphate synthase (DXS) is the rate-limiting enzyme in the plastidial methylerythritol phosphate pathway (MEP). In this study, PtDXS (XM_024607716.1) was isolated from Populus trichocarpa. A bioinformatics analysis revealed that PtDXS had high homology with the DXSs of other plant species. PtDXS expression differed among plant tissues and was highest in young leaves and lowest in roots. The recombinant protein was produced in Escherichia coli BL21 (DE3), purified, and its activity evaluated. The purified protein was capable of catalyzing the formation of 1-deoxy-d-xylulose-5-phosphate (DXP) from glyceraldehyde-3-phosphate and pyruvate. A functional color assay in E. coli harboring pAC-BETA indicated that PtDXS encodes a functional protein involved in the biosynthesis of isoprenoid precursors. The treatment of P. trichocarpa seedlings with 200 μM abscisic acid (ABA), 200 mM NaCl, 10% polyethylene glycol6000, and 2 mM H₂O₂ resulted in increased expression of PtDXS. The ABA and gibberellic acid contents of the transgenic lines (Poplar Nanlin 895) were higher than wild types, suggesting that DXS is important in terpenoid biosynthesis. Overexpression of PtDXS enhanced resistance to S. populiperda infection. Furthermore, the transgenic lines showed decreased feeding by Micromelalopha troglodyta, supporting the notion that PtDXS is a key enzyme in terpenoid biosynthesis.

Abstract
BACKGROUND Clinical alarms represent the top hazard listed in the "Top Ten Health Technology Hazards" report. Frequent false alarms can disrupt patient care and reduce trust in alarms. AIM The aim of the present study was to investigate the perceptions and practices of critical and noncritical care nurses regarding clinical alarms. METHODOLOGY This was a descriptive analytical study conducted from October 2016 to February 2017 at three hospitals on 197 nurses at Neyshabur University of Medical Sciences in Neyshabur, Northeastern Iran. Participants were selected through stratified random sampling. The perceptions were measured through the 2011 Health care Technology Foundation Clinical Alarms Survey. RESULTS More than half of the nurses believed that frequent false alarms reduced trust in alarms, leading nurses to inappropriately disable alarms. The nurses ranked frequent false alarms as the most important issue in response to alarms. More than 60% of the nurses indicated that they needed more training on the use of bedside and central monitors. CONCLUSION The result of this study suggested that frequent false alarms, as the most important issue related to alarms, should be taken into account by hospital administrators and researchers to decrease alarm fatigue and improve alarm system safety. More specialized clinical policies and procedures for alarm management should also be considered.

Abstract
Patient’s safety and staff in hospital is one issue that has always been considered as an important principle by experts in health systems. Therefore, for increase safety, standards and safety regulations must be considered. This study aims to evaluation of safety standards accomplishment in educational hospitals of Neyshabur University of medical Sciences. This cross-sectional descriptive study, safety standard status of all wards including 17 various wards from 22 Bahman hospital and 14 various wards from hakim Hospital in Neyshabur city (2016) was investigated. Data were collected using a questionnaire safety standard status hospitals (264 questions). Also data analyzed by SPSS16 software, using descriptive (Mean ± SD) and inferential statistics (T-Test). The results revealed that Safety standard status in 22bahman and hakim hospital were weak (2.42 ± 0.14) and moderate (3.04 ± 0.18) respectively. Also result showed in Hakim hospital, the highest and lowest safety standard status in Internal and Administrative-financial unit was (3.42 ± 0.19) (1.36 ± 0.58) respectively. In addition in hakim hospital, the highest and lowest safety standard status in operation room and administrative-financial unit (3.53 ± 0.28), 1.36 ± 0.58) respectively. According to the result, the safety condition in hospitals of Neyshabur city is moderate and poor status. However, imperfect implementation of safety protocols can endanger safety conditions in hospital. Therefore, it is necessary to take the required correcting measures to ensure full safety in hospitals. Safety is defined by development of systems for preventing incidents, injuries, and other unpleasant events in organizations. This article showed the safety status is not appropriate in most units of hospitals, which can lead to dangers for patients and personnel. It is suggested for future studies to compare the safety status of different provinces.

Nurses have an important role in the care of patients who suffered from life threatening diseases. End of life cares is one of the routine activities of nurses (Gott et al., 2012) [2]. We surveyed knowledge, attitude and practice of nurses who worked in the hospitals of Neyshabur University of Medical Sciences towards palliative care from January 2016 to May 2016. A self-administered Persian questionnaire was used for data collection. The attitude scale was adopted from Frommelt Attitude toward Care of the Dying (Frommelt, 1991) and the knowledge questions were adopted from the Palliative Care Quiz for Nursing (Ross et al., 1996). The practice questions were also adopted from different related studies. Data analysis was performed by SPSS Statistics software for windows version 16. Our study showed that majority of nurses had favorable attitude but poor knowledge and practice towards palliative care. The results emphasize the importance and need for developing palliative care services in our hospitals.

Abstract
Epigenetic modification by DNA methylation is necessary for all cellular processes, including genetic expression events, DNA repair, genomic imprinting and regulation of tissue development. It occurs almost exclusively at the C5 position of symmetric CpG and asymmetric CpHpG and CpHpH sites in genomic DNA. The RNA-directed DNA methylation (RDM1) gene is crucial for heterochromatin and DNA methylation. We overexpressed PtRDM1 gene from Populus trichocarpa to amplify transcripts of orthologous RDM1 in 'Nanlin895' (P. deltoides × P. euramericana 'Nanlin895'). This overexpression resulted in increasing RDM1 transcript levels: by ∼150% at 0 mM NaCl treatment and by ∼300% at 60 mM NaCl treatment compared to WT (control) poplars. Genomic cytosine methylation was monitored within 5.8S rDNA and histone H3 loci by bisulfite sequencing. In total, transgenic poplars revealed more DNA methylation than WT plants. In our results, roots revealed more methylated CG contexts than stems and leaves whereas, histone H3 presented more DNA methylation than 5.8S rDNA in both WT and transgenic poplars. The NaCl stresses enhanced more DNA methylation in transgenic poplars than WT plants through histone H3 and 5.8 rDNA loci. Also, the overexpression of PtRDM1 resulted in hyper-methylation, which affected plant phenotype. Transgenic poplars revealed significantly more regeneration of roots than WT poplars via NaCl treatments. Our results proved that RDM1 protein enhanced the DNA methylation by chromatin remodeling (e.g. histone H3) more than repetitive DNA sequences (e.g. 5.8S rDNA).

Abstract
Drought and salinity are two main abiotic stressors that can disrupt plant growth and survival. Various biotechnological approaches have been used to alleviate the problem of drought stress by improving water stress resistance in forestry and agriculture. The drought sensitive 1 (DRS1) gene acts as a regulator of drought stress, identified in human, yeast and some model plants, such as Arabidopsis thaliana, but there have been no reports of DRS1 transformation in poplar plants to date. In this study, we transformed the DRS1 gene from Populus trichocarpa into Populus deltoides × Populus euramericana 'Nanlin895' using Agrobacterium tumefaciens-mediated transformation. We confirmed that the DRS1 gene was transformed into 'Nanlin895' poplar genomes using reverse transcription polymerase chain reaction (PCR), multiplex PCR, real-time PCR, and sodium dodecyl sulfate-polyacrylamide gel electrophoresis. All transformed and wild-type (WT) plants were then transferred into a greenhouse for complementary experiments. We analyzed the physiological and biochemical responses of transgenic plants under drought and salt stresses in the greenhouse, and the results were compared with control WT plants. Responses to abiotic stress were greater in transgenic plants compared with WT. Based on our results, introduction of the DRS1 gene into poplar 'Nanlin895' plants significantly enhanced the resistance of those plants to water deficit and high salinity, allowing higher growth rates of roots and shoots in those plants. Additionally, the clawed root rate increased in transformed poplars grown in culture media or in soil, and improved survival under drought and salt stress conditions.

Abstract
Introduction: Diabetes mellitus is a risk factor for cardiovascular disease. Some recent studies have shown an association between diabetes and out-of-hospital cardiac arrest incidence and survival. We aimed to investigate whether there is an association between the presence of diabetes mellitus and survival after cardiopulmonary resuscitation (CPR) in patients with an in-hospital cardiac arrest.
Methods: A cross-sectional study was conducted during the period of January to February 2014, among 80 cases of cardiopulmonary arrest in patients at Qaem hospital of Mashhad, Iran. A code 99 was announced after a cardiac arrest was identified, and CPR was performed by the cardiac arrest team. Twenty four hour survival was compared in diabetic and non-diabetic patients who had a return to spontaneous circulation after CPR. We used SPSS statistics for Windows version 16 for data analysis.
Results: The return to spontaneous circulation in the diabetic group was not significantly lower than for the non-diabetic group (42.9% versus 61.0% [P = 0.15]). However, the 24-hour survival in the diabetic group was significantly lower than for the non-diabetic group (19.0% versus 44.1% [P = 0.04]).
Conclusion: The presence of diabetes mellitus is associated with a significantly lower rate of survival after CPR.

Abstract
Nucleoside diphosphate kinases (NDPKs) are multifunctional proteins that regulate a variety of eukaryotic cellular activities, including cell proliferation, development, and differentiation. NDPK2 regulates the expression of antioxidant genes in plants. In a previous study, the Arabidopsis thaliana NDPK2 gene (AtNDPK2) was found to be associated with H2O2-mediated mitogen-activated protein kinase signaling in Arabidopsis thaliana. Proteins from transgenic plants overexpressing AtNDPK2 showed higher levels of autophosphorylation and NDPK activity and lower levels of reactive oxygen species (ROS) than those of wild-type (WT) plants. Therefore, constitutive overexpression of AtNDPK2 in Arabidopsis plants conferred enhanced tolerance to multiple environmental stresses that elicit ROS accumulation in situ. In this study, we cloned the Populus trichocarpa NDPK2 gene and analyzed its molecular structure and function. We generated and evaluated transgenic poplar plants expressing the PtNDPK2 gene under the control of the 35S promoter to achieve enhanced tolerance to various abiotic stresses. Transgenic poplar plants showed enhanced tolerance to salt and drought stress at the whole-plant level. The transgenic poplar plants showed significantly greater tolerance to 200 mM NaCl and drought stresses than WT poplar plants. In addition, the transgenic plants exhibited better growth due to increased expression of auxin-related indole acetic acid genes under normal growth conditions compared with WT plants. Our results suggest that induction of PtNDPK2 overexpression in poplars will be useful for increasing biomass production in the presence of various abiotic stresses.
