Palladium single atoms on TiO2 as a photocatalytic sensing platform for analyzing organophosphorus pesticide chlorpyrifos.

Traditional methods for analyzing organophosphorus pesticide chlorpyrifos, usually require the tedious sample pretreatment and sophisticated bio-interfaces, inevitably leading to the difficulty for real-time analysis. Herein, we first adopt palladium single-atom (PdSA)/TiO 2 as an advanced photocatalytic sensing platform for directly detecting the chlorpyrifos with high sensitivity and selectivity through restricting the photocatalytic H 2 evolution activity of Pd single atom by chlorpyrifos. PdSA/TiO 2 , prepared by an in-situ photocatalytic reduction of PdCl 4 2- on the TiO 2 , shows much higher photocatalytic activity (10 mol g -1 h -1 ) for hydrogen evolution reaction (HER) than Pd nanoparticles (1.95 mol g -1 h -1 ), as well as excellent stability. However, in the presence of chlorpyrifos, the photocatalytic HER activity of PdSA/TiO 2 decreases more obviously due to the adsorption interaction of chlorpyrifos with highly dispersed PdSA than that of Pd nanoparticles, proved by X-ray photoelectron spectroscopy and mass spectra. Through this interesting inhibition effect of chlorpyrifos on the photocatalytic activity of PdSA/TiO 2 , the present sensing platform can realize a wide linear relationship ranged from 0.03 ng/mL to 10 μg/mL for the determination of chlorpyrifos with a very low detection limit of 0.01 ng/mL, much lower than the maximum residue limit (10 ppb) permitted by the U.S. Environmental Protection Agency. Moreover, this sensing platform can be allowed for the analysis of vegetable samples with the average recovery rates of 125%.
Regulated Acyl-CoA Synthetase Short-Chain Family Member 2 Accumulation during Spermatogenesis

Objective Acyl-CoA synthetase short-chain family member 2 (ACSS2) activity provides a major source of acetyl-CoA to drive histone acetylation. This study aimed to unravel the ACSS2 expression during mouse spermatogenesis, where a dynamic and stage-specific genome-wide histone hyperacetylation occurs before histone eviction. Materials and Methods In this experimental study, ACSS2 expression levels during spermatogenesis were verified by Immunodetection. Testis paraffin-embedded sections were used for IHC staining with anti-H4 pan ac and anti-ACSS2. Co-detection of ACSS2 and H4K5ac was performed on testis tubular sections by immunofluorescence. Proteins extracts from fractionated male germ cells were subjected to western-blotting and immunoblot was probed with anti- ACSS2 and anti-actin. Results The resulting data showed that the commitment of progenitor cells into meiotic divisions leads to a robust accumulation of ACSS2 in the cell nucleus, especially in pachytene spermatocytes (P). However, ACSS2 protein drastically declines during post-meiotic stages, when a genome-wide histone hyperacetylation is known to occur. Conclusion The results of this study are in agreement with the idea that the major function of ACSS2 is to recycle acetate generated after histone deacetylation to regenerate acetyl-CoA which is required to maintain the steady state of histone acetylation. Thus, it is suggested that in spermatogenic cells, nuclear activity of ACSS2 maintains the acetate recycling until histone hyperacetylation, but disappears before the acetylation-dependent histone degradation.
Bacterial survival in whole blood depends on plasma sensitivity and resistance to neutrophil killing

Whole blood (WB) is held at room temperature for not more than 24 hours before blood component manufacturing. The ability of several culture collection, skin‐derived, and transfusion‐related bacteria to survive in WB stored at 22 ± 2°C for 24 hours was investigated in this study.
AMPK activity is required for the induction of anhydrobiosis in a tardigrade Hypsibius exemplaris, and its potential up‐regulator is PP2A

The anhydrobiotic tardigrade, Hypsibius exemplaris, was previously considered to require de novo gene expression and protein phosphatase 1 (PP1) and protein phosphatase 2A (PP2A) activity for successful anhydrobiosis. These indicate that H. exemplaris has signal transduction systems responding to desiccation stress, with the involvement of phosphorylation events. To this end, we carried out time‐series phosphoproteomics of H. exemplaris exposed to mild desiccation stress and detected 48 phosphoproteins with significant differential regulations. Among them, immediate and successive reduction of phosphorylation levels of AMP‐activated protein kinase (AMPK) was observed. The subsequent chemical genetic approach showed that AMPK was activated during the preconditioning stage for anhydrobiosis, and inhibition of its activity impaired successful anhydrobiosis. As PP2A is known to dephosphorylate AMPK in other organisms, we suggested that decreased phosphorylation levels of AMPK upon mild desiccation stress were caused by dephosphorylation by PP2A. Accordingly, phosphoproteomics of animals pre‐treated with the PP1/PP2A inhibitor cantharidic acid (CA) lacked the decrease in phosphorylation levels of AMPK. These observations suggest that AMPK activity is required for successful anhydrobiosis in H. exemplaris, and its phosphorylation state is possibly regulated by PP2A.
Therapeutic and biological activities of berberine: The involvement of Nrf2 signaling pathway

Since the beginning of the 21st century, studies have focused on developing drugs from naturally occurring compounds. Berberine (Brb) as a plant‐derived compound is of interest. It is an isoquinone alkaloid which is derived from Berberis aristata, Berberis aquifolium and Berberis vulgaris. This plant‐derived compound has a variety of pharmacological effects such as antioxidant, anti‐inflammatory, antidiabetic, antidiarrheal, antitumor, antimicrobial, and anti‐inflammatory. Various studies have demonstrated the therapeutic and biological activities of Brb, but there is a lack of a precise review to manifest the signaling pathway of action of Brb. The nuclear factor erythroid 2‐related factor 2 (Nrf2) is a highly conserved pathway which mainly involves in preservation of redox balance. At the present review, we describe the therapeutic and biological activities of Brb as well as the relevant mechanisms specially focused on the Nrf2 signaling pathway.
The Effect of Melatonin on Mitochondrial Function and Autophagy in In Vitro Matured Oocytes of Aged Mice

Objective This study examined the in vitro effect of melatonin on the protein synthesis of mitochondria, as well as autophagy in matured oocytes of aged mice. Materials and Methods In this experimental study, germinal vesicles (GV) oocytes were collected from aged (with the age of six-months-old) and young mice (with age range of 6-8 weeks old) and then cultured in the in vitro culture medium (IVM) for 24 hours to each metaphase II (MII) oocytes and then supplemented with melatonin at a concentration of 10 μM. The culture medium of MII oocytes was devoid of melatonin. Afterward, the expression of the SIRT-1 and LC3 was assessed by immunocytochemistry. ATP-dependent luciferin-luciferase bioluminescence assay was employed for the measurement of the ATP contents. Intracellular reactive oxygen specious (ROS) was detected by DCFH-DA, and the total antioxidant capacity (TAC) level was determined by TAC assay. Results The expression of SIRT-1 and LC3, as well as the measurement of the ATP content, was significantly increased in oocytes treated with melatonin compared with the oocytes receiving no treatment. Moreover, TAC was considerably higher in melatonin-treated oocytes than oocytes receiving no treatment. On the other hand, the level of ROS was significantly decreased in oocytes treated with melatonin in comparison with the untreated oocytes. The results indicated that melatonin considerably improved the development of oocytes as well. Conclusion According to the data, melatonin increased mitochondrial function and autophagy via an increase in the expression of SIRT1 and LC3, as well as the ATP contents while it decreased the levels of ROS and increased TAC in oocytes derived from aged mice.
Circ_0026344 restrains metastasis of human colorectal cancer cells via miR-183

Abstract Background CircRNA circ_0026344 was previously revealed as a tumour-suppressive gene in colorectal cancer (CRC) progression. The purpose of this research was to investigate the role of circ_0026344 in CRC cells metastasis induced by chemokines. Methods Two human CRC cell lines SW480 and Caco-2 were treated by CCL20 and CXCL8. Cell proliferation, migration/invasion, expression of epithelial-mesenchymal transition (EMT) inducers and the expression of circ_0026344 were measured using sulforhodamine B assay, Transwell chamber, western blot and qRT-PCR, respectively. The effects of circ_0026344 on CRC cells migration/invasion and the expression of EMT inducers were evaluated. Moreover, the downstream miRNA and signalling pathways of circ_0026344 were studied. Results CCL20 and CXCL8 synergized to facilitate the proliferation, migration and invasion of CRC cells. At the meantime, E-cadherin was downregulated, whereas N-cadherin, Vimentin and Snail were up-regulated by CCL20 and CXCL8 co-stimulation, which was accompanied by the mobilization of PI3K/AKT/ERK signalling. More interestingly, the expression of circ_0026344 was down-regulated by CCL20 and CXCL8 co-stimulation. Silence of circ_0026344 increased the migratory and invasive capacities of CRC cells and increased EMT process as well. Overexpression of circ_0026344 led to a contrary impact. miR-183 was negatively regulated by circ_0026344, and the inhibitory effects of circ_0026344 overexpression on Wnt/β-catenin pathway were reversed when miR-183 was overexpressed. Conclusion Overexpression of circ_0026344 restrained CRC metastasis and EMT induced by CCL20 and CXCL8 synergistical treatment. miR-183 was a downstream effector of circ_0026344, and the anti-tumour function of circ_0026344 might be involved in the repressed Wnt/β-catenin signalling. Highlights CCL20 and CXCL8 synergize to decrease the expression of circ_0026344; Silence of circ_0026344 promotes CRC cells migration, invasion and EMT process; miR-183 is a downstream effector of circ_0026344.
Comparison of Outcomes at Time of Superior Cavopulmonary Connection Between Single Ventricle Patients With Ductal-Dependent Pulmonary Blood Flow Initially Palliated With Either Blalock-Taussig Shunt or Ductus Arteriosus Stent: Results From the Congenital Catheterization Research Collaborative.

BACKGROUND Patients with single ventricle anatomy and ductal-dependent pulmonary blood flow may be initially palliated with either modified Blalock-Taussig shunt (BTS) or ductus arteriosus stent (DAS). Comparisons of outcomes during the interstage period and at the time of superior cavopulmonary connection (SCPC) are lacking and may differ between palliation strategies. METHODS Infants with single ventricle anatomy and ductal-dependent pulmonary blood flow palliated with either DAS or BTS from 2008 to 2015 were reviewed across 4 centers. Interstage outcomes, and for those who had SCPC, anatomy, hemodynamics, and perioperative clinical outcomes were compared. Thirty-five patients with DAS and 136 patients with BTS were included. RESULTS At initial palliation, demographic, clinical variables, and pulmonary artery size were similar. Interstage death, transplant, or unplanned reintervention to treat cyanosis occurred in 25.7% of DAS and 35.8% of BTS, P=0.27. Reintervention was more common with DAS (48.6% versus 2.2%; P<0.001). Twenty-three DAS patients and 111 BTS patients underwent SCPC. Preoperative hemodynamics and overall pulmonary atresia growth were similar, although right pulmonary artery growth was better with DAS (change in z-score: 1.57 versus 0.65, P=0.026). SCPC intraoperative and postoperative courses were similar. CONCLUSIONS In patients with single-ventricle anatomy and ductal-dependent pulmonary blood flow, interstage outcomes, hemodynamics before SCPC, and acute postoperative outcomes were similar. Overall reintervention was more common in the DAS group, driven by more frequent planned reintervention. Unplanned reintervention, death, and transplant were similar. Both groups demonstrated good pulmonary atresia growth. DAS is a reasonable initial palliative alternative to BTS in select patients.
Engineering of Saccharomyces cerevisiae for the production of (+)‐ambrein

The triterpenoid (+)‐ambrein is the major component of ambergris, a coprolite of the sperm whale that can only be rarely found on shores. Upon oxidative degradation of (+)‐ambrein, several fragrance molecules are formed, amongst them (−)‐ambrox, one of the highest valued compounds in the perfume industry. In order to generate a Saccharomyces cerevisiae whole‐cell biocatalyst for the production of (+)‐ambrein, intracellular supply of the squalene was enhanced by overexpression of two central enzymes in the mevalonate and sterol biosynthesis pathway, namely the N‐terminally truncated 3‐hydroxy‐3‐methylglutaryl‐CoA reductase 1 (tHMG) and the squalene synthase (ERG9). In addition, another key enzyme in sterol biosynthesis, squalene epoxidase (ERG1) was inhibited by an experimentally defined amount of the inhibitor terbinafine in order to reduce flux of squalene towards ergosterol biosynthesis while retaining sufficient activity to maintain cell viability and growth. Heterologous expression of a promiscuous variant of Bacillus megaterium tetraprenyl‐β‐curcumene cyclase (BmeTC‐D373C), which has been shown to be able to catalyse the conversion of squalene to 3‐deoxyachillol and then further to (+)‐ambrein resulted in production of these triterpenoids in S. cerevisiae for the first time. Triterpenoid yields are comparable with the best microbial production chassis described in literature so far, the methylotrophic yeast Pichia pastoris. Consequently, we discuss similarities and differences of these two yeast species when applied for whole‐cell (+)‐ambrein production.
Why Adolescents Attempt Suicide: A Qualitative Study of the Transition from Ideation to Action

To ameliorate the public health problem of adolescent suicide, it is imperative to go beyond simply establishing which factors increase risk. Multiple factors often interact in such a way that escalates suicide risk, and some combinations may be particularly perilous. Therefore, it is essential to examine the sequence and interplay of these various contributors to understand how they interact to confer risk. To enhance our understanding of this process, we used qualitative in-depth interviews with 20 psychiatrically hospitalized adolescents who had recently made a suicide attempt to investigate the factors that contributed to their attempts. In this qualitative analysis we 1) identified 16 separate factors that contributed to their suicide attempts, and 2) focused on the sequence and interplay between these factors in order to better understand why adolescents attempt suicide, with specific attention to which factors facilitated the transition from suicide ideation to action. Findings demonstrated that the strain caused by historical, sociocultural, and interpersonal factors alone was not enough to result in adolescents attempting suicide. For all but two participants, it was the interaction of intrapersonal factors that appeared to distort cognitions and/or elevate emotions to the point where they became intolerable and suicide became a viable option. These intrapersonal factors appeared to be the catalyst in the process from suicide ideation to action. Our findings suggest the need for specific strategies that address cognitive distortions, emotion dysregulation, and feelings of invalidation and entrapment as potential targets for interventions and prevention practices with adolescents at risk for suicide.
Validity and reliability of the Turkish Occupational Balance Questionnaire (OBQ11-T)

Abstract Background: Occupational balance (OB) is an important concept in occupational therapy and is considered as an essential component of health and well-being. Aim: The aim of this study was to investigate the validity and reliability of the Turkish version of the Occupational Balance Questionnaire-11 (OBQ11-T). Materials and methods: The OBQ11-T was administered to 116 individuals for construct validity analysis and to 58 individuals for reliability analysis. Validity was determined using explanatory and confirmatory factor analysis. In confirmatory factor analysis, RMSEA (root mean square error of approximation) value, comparative fit index (CFI), and Chi-square to degrees of freedom ratio (CMIN/DF) were analysed. The test–retest method and Cronbach’s alpha coefficient were used to assess the reliability and internal consistency of the OBQ11-T, respectively. Results: The model fit the data according to the indices of relative fit (RMSEA = 0.076, CMIN/DF = 1.661, and CFI = 0.875). The correlation coefficient between test and retest OBQ11-T total scores was 0.922. Total scores showed a significant statistical relationship (p < 0.01), indicating good reliability. Cronbach’s alpha for OBQ11-T total score was 0.785, indicating acceptable internal consistency. Conclusions and significance: The current study demonstrates that the OBQ11-T is a valid and reliable tool for measuring the self-rated OB of healthy individuals.
Being a teenager and cancer patient: What do adolescents and young adults with cancer find valuable and challenging with their friends and cancer peers?

Abstract Purpose: This study examined Adolescent and Young Adult (AYA) cancer patients’ experiences with friends and cancer friends (peers) throughout their cancer journey. Research approach: Qualitative, thematic analysis. Participants: Twelve AYA diagnosed with cancer, treated within the past five years. Methodological approach: Individual semi-structured interviews, focusing on friend and peer experiences pre-/post-diagnosis, during and after treatment. Findings: Overarching themes of ‘valued’ vs. ‘challenging’ aspects with friends and peers. Interpretation: Friend and peer relationships were both valuable, but in different ways. Friends provided general support and helped AYA feel like a normal teenager, while peers provided targeted support and helped AYA feel like a normal teenager with cancer. Peers had an intimate understanding of cancer, whereas poor understanding by friends led to further challenges such as avoidance and being dismissive. Peer relations were notably challenged by a premature confrontation with mortality. Friendships evolved and changed throughout the cancer journey.
Dose-Response Association Between Level of Physical Activity and Mortality in Normal, Elevated, and High Blood Pressure.

It has been a challenge to verify the dose of exercise that will produce the maximum health benefits in hypertension. This study aimed to explore the association between level of daily physical activity, all-cause mortality and cardiovascular outcome at different blood pressure levels. A random sample of 18 974 white men and women aged 20 to 98 years were examined in a prospective cardiovascular population study. Self-reported activity level in leisure-time was drawn from the Physical Activity Questionnaire (level I: inactivity; II: light activity; and III: moderate/high-level activity). Blood pressure was defined as normal blood pressure: <120/<80 mm Hg; Prehypertension: 120-139/80-89 mm Hg; Stage I hypertension: 140-159/90-99 mm Hg; Stage II hypertension ≥160/≥100 mm Hg. The mean follow-up time was 23.4±11.7 years. At all levels of blood pressure, higher levels of physical activity were associated with lower all-cause mortality in a dose-response pattern. The pattern remained unchanged after adjustment for following confounders: sex, age, smoking status, education, diabetes mellitus, previous cardiovascular disease, body mass index, and calendar time. Compared with inactivity, following hazard ratios were found for stage I hypertension: light activity, hazard ratio 0.78 (0.72-0.84; P<0.001), moderate/high-level activity, hazard ratio 0.69 (0.63-0.75; P<0.001). At all levels of blood pressure, the risk of cardiovascular events was significantly reduced independent of the level of physical activity. In conclusion, the association between physical activity and all-cause mortality was present in an inverse dose-response pattern at all levels of blood pressure. Physical activity was associated with reduction in cardiovascular events independent of the level of physical activity.
Cross-sectional study of the relationship between cloth udder towel management, towel bacteria counts, and intramammary infection in late-lactation dairy cows.

Because cloth udder towels (CUT) may function as a fomite for mastitis-causing pathogens, most udder health laboratories offer towel culture services as a tool to monitor towel hygiene. However, no studies have investigated if an association exists between bacteria levels in CUT and udder health outcomes. The objectives of this cross-sectional study were to (1) describe associations between herd-level measures of towel bacteria count (ToBC) and quarter-level intramammary infection (IMI) status in late-lactation cows, (2) establish pathogen-specific target levels of bacteria in CUT to aid the interpretation of towel culture reports, and (3) identify laundering-related risk factors for high ToBC. The study was conducted in 67 herds from 10 dairy states in the United States that used CUT. These 67 herds were originally recruited as part of a larger (80 herd) cross-sectional study of bedding management. Each herd was visited once during December 2017 to April 2018 and quarter-milk samples (n = 4,656) were collected from late-gestation (>180 d pregnant) cows (n = 1,313). Two recently laundered CUT were collected and a questionnaire was used to collect information about pre-milking teat preparation and CUT management practices. Quarter-level IMI status was determined using standard bacteriologic methods. In addition, colony-forming units of all bacteria (total bacteria), Staphylococcus spp. , Streptococcus spp. or Streptococcus-like organisms (SSLO), coliforms, noncoliform gram-negatives, and Bacillus spp. were determined for each pair of CUT (log10 cfu/cm2). The association between ToBC and IMI was determined using multivariable logistic regression with mixed effects. After dichotomizing ToBC into high and low categories, associations between towel management practices and ToBC category were determined using unconditional logistic regression. The quarter-level prevalence of IMI was 19.6%, which was predominantly caused by non-aureus Staphylococcus spp. (NAS; 10.2%) and SSLO (5.1%). The predominant bacteria in CUT were Bacillus spp. (median = 3.13 log10 cfu/cm2). Total bacteria count was not associated with odds of IMI (odds ratio = 1.06), likely due to the predominance of Bacillus spp. in CUT and low number of IMI caused by Bacillus spp. In contrast, counts of Staphylococcus spp. and SSLO were positively associated with odds of IMI caused by NAS (odds ratio = 1.33) and SSLO (odds ratio = 1.45), respectively. Of 12 CUT management practices evaluated, only the failure to use a dryer was identified as a clear predictor of risk for a high ToBC (risk ratio of high coliform count = 8.17). Our study findings suggest that CUT may act as a fomite for NAS and SSLO. We recommend that herds aim to keep counts of Staphylococcus spp. and SSLO in CUT below 32 cfu/cm2 (or 5 cfu/in2), and that laundered towels be completely dried in a hot air dryer.
