RESUMO

PURPOSE: This open-trial pilot study evaluated the feasibility and effectiveness of acupuncture with brief therapy (ABT) for individuals with posttraumatic stress disorder (PTSD). METHOD: Participants included 27 individuals with PTSD diagnoses confirmed using the Clinician-Administered PTSD Scale for DSM-5. Before ABT, 22 participants completed eight acupuncture sessions and three telehealth sessions of a brief treatment program for PTSD (Brief Relaxation, Education, and Trauma Healing [BREATHE]). RESULTS: ABT significantly reduced PTSD symptoms, depression symptoms, anxiety, and improved trauma-related cognition. CONCLUSION: Acupuncture can play an important role in mental health recovery, and combining acupuncture with a brief, telehealth-based treatment (BREATHE) may assist recovery among individuals with PTSD.

RESUMO

Consumers are more inclined to choose beef with a high intramuscular fat content (IMF), which regulated by lots of factors. It is very significant to find a miRNA that plays a key role in the accumulation of IMF. In our study, we found that bta-miR-330 was highly expressed in Japanese black cattle and differentially expressed at intramuscular pre-adipocytes differentiation processes. Furthermore, we transfected the bta-miR-330 mimic & inhibitor in intramuscular pre-adipocytes. The results showed that bta-miR-330 inhibits the proliferation but promotes the adipogenesis of intramuscular pre-adipocytes. Subsequently, our study showed that bta-miR-330 binds to SESN3, which inhibits the adipogenesis of intramuscular pre-adipocytes. Moreover, we established the mechanism that bta-miR-330 promotes the adipogenesis of intramuscular pre-adipocytes by targeting SESN3 to activate the Akt-mTOR signaling pathway. Overall, our results revealed that bta-miR-330-SESN3-Akt-mTOR axis plays an important role in adipogenesis of intramuscular pre-adipocytes, which provides a molecular basis for increasing IMF content in beef cattle.

RESUMO

Young people's mental health globally has been in decline. Because of their low perceived need, young people's services tend to be the first cut when budgets are reduced. There is a lack of evidence on how a reduction in services and opportunities for young people is associated with their mental health. Additionally, how this may be magnified by place and the assets and challenges of place. The aim of this study is to explore trends in young people's mental health measured by GHQ-12 over time in the twelve regions of the UK. We estimated an interrupted time series model using 2010 as a break point from which there was a shift in government policy to a prolonged period of large reductions in central government funding. Repeated cross-sectional data on young people aged 16-25 is used from the British Household Panel Survey and its successor survey UK Household Longitudinal Survey. Results showed a statistically significant reduction in mental health for young people living in the North East, Wales, and the East of England. The North East was the region with the largest reduction in funding and saw the greatest reduction in young people's mental health. Next, we look at how reductions in local government expenditure related to services for children and young people: children's social services, education, transportation, and culture; explain the observed decline in mental health. We employ a Blinder-Oaxaca Decomposition approach comparing young people's mental health between 2011 and 2017. Results show a marginally statistically significant decrease in young people's mental health over this time. Unobserved factors related to transport spending and children's social services explain some of this gap. Area level factors such as deprivation, infrastructure, and existing assets need to be considered when distributing funding for young people's services to avoid exacerbating regional inequalities in mental health.

RESUMO

OBJECTIVES: Most type 2 diabetes simulation models utilise equations mapping out lifetime trajectories of risk factors [e.g. glycated haemoglobin (HbA1c)]. Existing equations, using historic data or assuming constant risk factors, frequently underestimate or overestimate complication rates. Updated risk factor time path equations are needed for simulation models to more accurately predict complication rates. AIMS: (1) Update United Kingdom Prospective Diabetes Study Outcomes Model (UKPDS-OM2) risk factor time path equations; (2) compare quality-adjusted life-years (QALYs) using original and updated equations; and (3) compare QALY gains for reference case simulations using different risk factor equations. METHODS: Using pooled contemporary data from two randomised trials EXSCEL and TECOS (n = 28,608), we estimated: dynamic panel models of seven continuous risk factors (high-density lipoprotein cholesterol, low density lipoprotein cholesterol, HbA1c, haemoglobin, heart rate, blood pressure and body mass index); two-step models of estimated glomerular filtration rate; and survival analyses of peripheral arterial disease, atrial fibrillation and albuminuria. UKPDS-OM2-derived lifetime QALYs were extrapolated over 70 years using historical and the new risk factor equations. RESULTS: All new risk factor equation predictions were within 95% confidence intervals of observed values, displaying good agreement between observed and estimated values. Historical risk factor time path equations predicted trial participants would accrue 9.84 QALYs, increasing to 10.98 QALYs using contemporary equations. DISCUSSION: Incorporating updated risk factor time path equations into diabetes simulation models could give more accurate predictions of long-term health, costs, QALYs and cost-effectiveness estimates, as well as a more precise understanding of the impact of diabetes on patients' health, expenditure and quality of life. TRIAL REGISTRATION: ClinicalTrials.gov NCT01144338 and NCT00790205.

RESUMO

BACKGROUND: Ultrapluse CO2 fractional laser technology has emerged as an effective treatment for scar management. However, one drawback of this modality is the pain caused during the procedure. This study aims to explore the efficacy and safety of dezocine (DZC) as preemptive analgesia for reduction of pain induced by ultrapulse CO2 fractional laser treatment for acne scars. METHODS: The study cohort included 78 outpatients with acne scars between February and April 2023. Patients were randomly assigned into three groups with intravenous injection (iv) of DZC prior to laser treatment: (1) control, iv of saline; (2) DZC group 1 (DZC_1), iv of DZC at 0.15 mg/kg; and (3) DZC_2, iv of DZC at 0.20 mg/kg. After 30 min, one session of ultrapulse CO2 fractional laser treatment on acne scars was performed. Hemodynamics, visual analogue scale (VAS), and anxiety visual analog test (AVAT) were monitored prior to, during, and after the procedure. RESULTS: Operative success rates for patients in the control, DZC_1, and DZC_2 groups were 34.6%, 84.6%, and 100%, respectively. DZC administered with either dosage significantly reduced the VAS and AVAT scores of patients in treatment groups as compared with the subjects in the control group during the course of ultrapulse CO2 fractional laser treatment. Patients in DZC_1 and DZC_2 groups did not show any significant difference in hemodynamic parameters, VAS, and AVAT scores. Temporary adverse effects such as nausea and dizziness were observed in some subjects after treatment; the symptoms were quickly dissolved after a rest in supine position. CONCLUSIONS: DZC as preemptive analgesia could effectively reduce pain and anxiety induced by ultrapulse CO2 fractional laser treatment in patients. This study provided an option of preemptive anesthesia to minimize the pain and discomforts associated with laser treatments in clinical practices.

RESUMO

Mechanistic target of rapamycin complex 1 (mTORC1) is a conserved serine/threonine kinase that integrates various environmental signals to regulate cell growth and metabolism. mTORC1 activation requires tethering to lysosomes by the Ragulator-Rag complex. However, the dynamic regulation of the interaction between Ragulator and Rag guanosine triphosphatase (GTPase) remains unclear. In this study, that LAMTOR1, an essential component of Ragulator, is dynamically ubiquitinated depending on amino acid abundance is reported. It is found that the E3 ligase TRAF4 directly interacts with LAMTOR1 and catalyzes the K63-linked polyubiquitination of LAMTOR1 at K151. Ubiquitination of LAMTOR1 by TRAF4 promoted its binding to Rag GTPases and enhanced mTORC1 activation, K151R knock-in or TRAF4 knock-out blocks amino acid-induced mTORC1 activation and accelerates the development of inflammation-induced colon cancer. This study revealed that TRAF4-mediated LAMTOR1 ubiquitination is a regulatory mechanism for mTORC1 activation and provides a therapeutic target for diseases involving mTORC1 dysregulation.

RESUMO

Studies suggest that a three-session brief treatment program (Brief Relaxation, Education, and Trauma Healing [BREATHE]) can help treat posttraumatic stress disorder (PTSD) and symptoms of trauma; however, the program has not been examined via telehealth. Thus, the current study evaluated the feasibility of BREATHE delivered via telehealth. The intervention included breathing retraining and psychoeducation about PTSD and trauma. Thirty participants from the community with confirmed PTSD diagnoses participated in this telehealth program. Treatment retention was high, and participants showed decreased PTSD symptoms, posttraumatic cognitions, depression, anxiety, overall psychiatric symptoms, and internalized stigma and increased resiliency at posttreatment and 3-month follow up. Results suggest that a telehealth brief treatment program for PTSD is feasible and effective for individuals with PTSD. [Journal of Psychosocial Nursing and Mental Health Services, xx(x), xx-xx.].

RESUMO

RATIONALE: Abdominal pregnancy is a rare ectopic pregnancy and its diagnosis and treatment are more challenging than those of other ectopic pregnancies. Because of a variable pregnancy site, abdominal pregnancy is associated with an increased risk of fatal abdominal hemorrhage, and consequently, an increased risk of maternal death compared with intrauterine pregnancy. DIAGNOSES: Pelvic infundibulum ligament pregnancy complicated with massive hemorrhage. PATIENT CONCERNS: 42-year-old pregnant woman who did not undergo an obstetric examination during the first trimester presented with sudden abdominal pain during the second trimester. Abdominal pregnancy was confirmed after emergency treatment, causing difficulty in the comprehensive preoperative evaluation.Interventions: In order to save the patient life, we actively carried out surgical treatment. OUTCOMES: The patient recovered well after the operation and was discharged on the 11th postoperative day. Blood ß-human chorionic gonadotropin (ß-hCG) levels and routine blood test results were normal 1 month after the surgery, and the patient had recovered. LESSONS: Several challenges are encountered in the diagnosis of abdominal pregnancy with regard to insufficient economic, cultural, and medical resources. In case of ectopic pregnancies, surgery should be the first choice of treatment, and preparations of blood transfusion are essential to combat the risk of rapid hemorrhagic shock caused by placenta implantation in the infundibulum ligament of the pelvis. The operation must be performed by experienced obstetricians and gynecologists.

RESUMO

Both ammonium sulfite slurry (ASS) from ammonia-based desulfurization and lignite are waste materials with low value. In this work, an innovative method was developed by applying ASS in lignite activation to produce water-soluble humic substances (WHSs) with a high bioactivity and economic value. The optimal activation method was to mix lignite and ASS at a 4:1-liquid-solid ratio by vortex blender and then oscillate it for 30 min at 25 °C. Compared with that of the unactivated lignite (UAL), the yield of WHSs from activated lignite (AL) increased by 42.72%. WHSs from AL consisted of a large number of aliphatic carbons with low molecular weight and functional groups such as amides, amines, sulfonic acid groups, C-O, and so forth. Moreover, WHSs from AL at lower concentrations (2 mg/L) has a more obvious root-elongation-promoting effect than WHSs from UAL (10 mg/L). Activation experiment with the lignite-related model compounds revealed that ASS caused the breakage of Caliph-O, Caliph-Caliph, and Carom-Caliph linkages between aromatic rings. These findings provide a theoretical basis for the development of green and sustainable technologies for the beneficial reuse of ASS and lignite in agriculture.

RESUMO

Engineered extracellular vesicles (EVs) are considered excellent delivery vehicles for a variety of therapeutic agents, including nucleic acids, proteins, drugs, and nanomaterials. Recently, several studies have indicated that clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9) delivered by EVs enable efficient DNA editing. However, an RNA editing tool delivered by EVs is still unavailable. Here, a signal peptide-optimized and EVs-delivered guide RNA (gRNA) and CRISPR/CasRx (Cas13d) system capable of rapidly inhibiting the expression of targeted genes with quick catabolism after performing their functions is developed. EVs with CRISPR/CasRx and tandem gRNAs targeting pivotal cytokines are further packed whose levels increase substantially over the course of acute inflammatory diseases and find that these engineered EVs inhibit macrophage activation in vitro. More importantly, this system attenuates lipopolysaccharide (LPS)-triggered acute lung injury and sepsis in the acute phase, mitigating organ damage and improving the prognosis in vivo. In summary, a potent tool is provided for short-acting RNA editing, which could be a powerful therapeutic platform for the treatment of acute diseases.

RESUMO

OBJECTIVE: This study explores the use of social media and its impact on the college life of students with disabilities. PARTICIPANTS: 341 college students who identified as having disabilities were recruited from two universities in the Northeastern United. METHODS: Multivariate multiple regression models examined the relationship between social media use and academic achievement, social connectedness, and work preparedness. RESULTS: The findings indicate that students' GPA was not associated with any social media use variables, but the time spent on using social media was negatively associated with the work hope and social connectedness. Social media learning was positively associated with work preparedness and social connectedness. CONCLUSIONS: The study findings suggest that social media used for learning purposes can have a positive impact on career and social development among college students with disabilities. However, the time spent for non-learning purposes did not show positive benefits.

RESUMO

BACKGROUND: Smoking continues to be a major health concern among persons with mental illnesses. AIMS: This pilot study compared smoking outcomes between wellness-coaching for smoking cessation and a control group. METHODS: Thirty-one individuals were enrolled in an educational group on smoking cessation and 23 completed an eight-session manualized education. Following this educational group, 11 of 23 participants were randomly assigned to wellness coaching for four months and 12 to a control condition. ANCOVAs were used to compare group differences in smoking outcomes. RESULTS: Fagerström Nicotine Dependence Index (FTND) score of the participants who received the wellness coaching intervention decreased significantly as compared to the control group, indicating a lower level of nicotine dependence. The outcomes of average number of cigarettes smoked daily and breath carbon monoxide level showed tendencies towards reductions for wellness coaching, although not statistically significant compared to the control condition. CONCLUSIONS: Suggestions are shared about the feasibility of wellness coaching as well as barriers and challenges learned in implementing such an intervention to assist individuals with mental illnesses in quitting or reducing smoking.

RESUMO

In this paper, a new type of single-faced superposed shear wall system is proposed based on the single-faced superposed shear wall structure. The nonlinear finite element analysis of a new splicing form of single-faced superposed shear wall components is carried out by using the method of combining experimental research and ABAQUS finite element software analysis. The impact of noncolumn on the connection performance of vertical seam is studied. The analysis shows no significant difference in the effect of eliminating concealed column on the hysteretic performance and bearing capacity of the single-faced superposed shear wall with the joint. The single-faced composite shear wall with two different splicing forms presents bending-shear failure. The single-faced composite shear wall model without concealed column design can also maintain good overall performance and seismic behavior.

RESUMO

Objective Assessing experiences and impact on wellness among international students during the COVID-19 pandemic. Participants: 405 undergraduate and graduate international students from 65 countries studying at a large public university. Methods: An online, voluntary and anonymous survey consisting of 50 quantitative and qualitative questions was conducted through Qualtrics. Descriptive and frequency analyses were used. Results: 27% of the students had concerns about the changes in student visa status that could seriously disrupt their studies in the U.S. 66.2% of them reported a moderate level, 18.8% reported a high level of stress related to the pandemic. Students identified the highest confidence in getting tested for infection but the lowest confidence in getting treatment if infected. They preferred telehealth for mental health services. Conclusions: Universities can best help international students by assisting with student visa and international travel issues, access to treatment for COVID-19 infection and developing telehealth for mental health services.

RESUMO

OBJECTIVE: This one-year follow-up study examined the changes of impact of using social media among college students with disabilities from the initial survey. PARTICIPANTS: 193 students completed the follow-up survey of the 341 who agreed to participate. METHODS: Paired t-test compared the changes in social media usage between the two surveys. Multiple linear regressions examined the relationship of social media use variables and social media addiction, career networking, disability subtypes between the two surveys. RESULTS: The daily average time spent on social media remained similar over one year. However, the level of social media addiction increased, especially among male students. One positive change was that students spent more time using social media for career networking purposes. CONCLUSION: Public awareness and education of social media addiction should be raised. Additionally, students could benefit from being guided and encouraged to use social media for positive activities such as career networking.

RESUMO

Long non-coding RNAs (lncRNAs) are emerging as versatile regulators in diverse biological processes. However, little is known about their cis- and trans-regulatory contributions in gene expression under salt stress. Using 27 RNA-seq data sets from Populus trichocarpa leaves, stems and roots, we identified 2988 high-confidence lncRNAs, including 1183 salt-induced differentially expressed lncRNAs. Among them, 301 lncRNAs have potential for positively affecting their neighboring genes, predominantly in a cis-regulatory manner rather than by co-transcription. Additionally, a co-expression network identified six striking salt-associated modules with a total of 5639 genes, including 426 lncRNAs, and in these lncRNA sequences, the DNA/RNA binding motifs are enriched. This suggests that lncRNAs might contribute to distant gene expression of the salt-associated modules in a trans-regulatory manner. Moreover, we found 30 lncRNAs that have potential to simultaneously cis- and trans-regulate salt-responsive homologous genes, and Ptlinc-NAC72, significantly induced under long-term salt stress, was selected for validating its regulation of the expression and functional roles of the homologs PtNAC72.A and PtNAC72.B (PtNAC72.A/B). The transient transformation of Ptlinc-NAC72 and a dual-luciferase assay of Ptlinc-NAC72 and PtNAC72.A/B promoters confirmed that Ptlinc-NAC72 can directly upregulate PtNAC72.A/B expression, and a presence/absence assay was further conducted to show that the regulation is probably mediated by Ptlinc-NAC72 recognizing the tandem elements (GAAAAA) in the PtNAC72.A/B 5' untranslated region (5'-UTR). Finally, the overexpression of Ptlinc-NAC72 produces a hypersensitive phenotype under salt stress. Altogether, our results shed light on the cis- and trans-regulation of gene expression by lncRNAs in Populus and provides an example of long-term salt-induced Ptlinc-NAC72 that could be used to mitigate growth costs by conferring plant resilience to salt stress.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has resulted in catastrophic damage worldwide. Accordingly, the development of powerful, safe, easily accessible vaccines with long-term effectiveness is understood as an urgently needed countermeasure against this ongoing pandemic. Guided by this strong promise of using AAVs, we here designed, optimized, and developed an AAV-based vaccines (including AAV-RBD(max), AAV-RBD(wt), AAV-2xRBD, and AAV-3xRBD) that elicit strong immune responses against the RBD domain of the SARS-CoV-2 S protein. These immunogenic responses have proven long-lived, with near peak levels for at least six months in mice. Notably, the sera immunized with AAV-3xRBD vaccine contains powerful neutralizing antibodies against the SARS-CoV-2 pseudovirus. Further evidence proven that potent specific antibodies could also be elicited in canines after vaccination with AAV-3xRBD vaccine.

RESUMO

Precision mapping of glycans at structural and site-specific level is still one of the most challenging tasks in the glycobiology field. Here, we describe a modularization strategy for de novo interpretation of N-glycan structures on intact glycopeptides using tandem mass spectrometry. An algorithm named StrucGP is also developed to automate the interpretation process for large-scale analysis. By dividing an N-glycan into three modules and identifying each module using distinct patterns of Y ions or a combination of distinguishable B/Y ions, the method enables determination of detailed glycan structures on thousands of glycosites in mouse brain, which comprise four types of core structure and 17 branch structures with three glycan subtypes. Owing to the database-independent glycan mapping strategy, StrucGP also facilitates the identification of rare/new glycan structures. The approach will be greatly beneficial for in-depth structural and functional study of glycoproteins in the biomedical research.

RESUMO

Detection of endogenous signals and precise control of genetic circuits in the natural context are essential to understand biological processes. However, the tools to process endogenous information are limited. Here we developed a generalizable endogenous transcription-gated switch that releases single-guide RNAs in the presence of an endogenous promoter. When the endogenous transcription-gated switch is coupled with the highly sensitive CRISPR-activator-associated reporter we developed, we can reliably detect the activity of endogenous genes, including genes with very low expression (<0.001 relative to Gapdh; quantitative-PCR analysis). Notably, we could also monitor the transcriptional activity of typically long non-coding RNAs expressed at low levels in living cells using this approach. Together, our method provides a powerful platform to sense the activity of endogenous genetic elements underlying cellular functions.

RESUMO

The cultural background of participants has not been considered in studies of dietary intake and depression, even though food choices are affected by culture. This study aims to examine the dietary patterns of people from diverse backgrounds and the correlation of diet and risk of depression. Relationships between depression and nutrient intake were analyzed with 4747 adult respondents from NHANES data. Multiple regressions were used with depression as dependent variable. Nutrient intake pattern differed among ethnic groups. After considering demographic factors, total fat and protein intake ratio to energy were associated with depressive symptoms among Hispanic respondents. Among White, dietary fiber and sugar were associated with depressive symptoms, and among Black, energy was associated with depressive symptoms. Total sugar and dietary fiber were associated with depressive symptoms among Asian. The relationship between depressive symptoms and nutrient intake varied based on the cultural background of participants.
