Local soil water limitation might also cause greater stomatal regulation in declining trees, indicated by lower intercellular CO2 concentration. Thus, site-specific soil moisture conditions growth sensitivity to global warming resulting in site-specific decline episodes in drought-prone areas.
There is preliminary evidence that the anticonvulsant topiramate increases the likelihood of both smoking and alcohol abstinence among smokers with alcohol use disorder (AUD), but its therapeutic mechanism has not been determined. We used event-related potentials (ERPs) to evaluate topiramate's effect on the salience of drug-related, emotional, and neutral pictorial cues to identify whether one of its potential therapeutic mechanisms involves reduction of the salience of motivationally relevant cues.

Participants enrolled in a multisite clinical trial treating smokers with AUD were randomly assigned to receive placebo, low-dose topiramate (up to 125mg/day), or high-dose topiramate (up to 250mg/day), along with brief behavioral compliance enhancement treatment. A subsample (n=101) completed ERP assessments at baseline (1week pre-medication) and week 5 (5weeks on medication; 1week pre-quit). We assessed the salience of pleasant, unpleasant, cigarette-related, alcohol-related, and neutral pictorial cues usin AUD. However, the nonsignificant mediation analyses preclude any firm conclusions about whether this effect represents one of topiramate's therapeutic mechanisms of action.
Leadership deficits and poor communication about COVID-19 (C-19) science connect risk-shifting and vaccination hesitancy to safety issues for nurses and the general public.

Nurses can be trusted, especially in these chaotic times, to provide trustworthy information on C-19. Publicly expressed gratitude to nurses does little to improve work environments made more precarious by C-19. Practical support may help retain nurses in the health system.

Public trust in governments has dissipated during the pandemic. People are confused by inconsistent and contentious information and services. Publishing practices that produce low-quality publications undermine scientific information and impede the flow of high-quality research information.

Science can advise on a pathway through the risks of C-19 but it is politicians and government officials who decide policy on whether to accept the science and set the level of acceptable risk to the general public. Problematic publishing and communication pathways for essentral to policy deliberations that affect transmission or spending on infection risk reduction. Policies that put nurses at increased risk encourage those with a choice, to abandon unsafe health system employment. Research quality systems that improve research communication pathways to support practice are urgently needed. selleck chemicals llc Nurses rely on research information sources for credible evidence to support their clinical practice. Risk-shifting is the unintended consequence of government policy on vaccination, immigration, international travel, quarantine and screening for C-19. Governments must accept their role in generating public mistrust of vaccines and not judge people's decisions made on the basis of information available. Political manipulation of C-19 data needs to be exposed to enable recovery planning.
Typically, the current dose prediction models are limited to small amounts of data and require retraining for a specific site, often leading to suboptimal performance. We propose a site-agnostic, three-dimensional dose distribution prediction model using deep learning that can leverage data from any treatment site, thus increasing the total data available to train the model. Applying our proposed model to a new target treatment site requires only a brief fine-tuning of the model to the new data and involves no modifications to the model input channels or its parameters. Thus, it can be efficiently adapted to a different treatment site, even with a small training dataset.

This study uses two separate datasets/treatment sites data from patients with prostate cancer treated with intensity-modulated radiation therapy (source data), and data from patients with head-and-neck cancer treated with volumetric-modulated arc therapy (target data). We first developed a source model with 3D UNet architecture, trained ffer learning. Our proposed model can make accurate predictions with limited training data.

No study to date has investigated an intervention program for male athletes that targets eating disorder risk factors. The purpose of this study was to measure the effects of the Male Athlete Body Project (MABP), an adaptation of the Female Athlete Body Project on body dissatisfaction, drive for muscularity, body-ideal internalization, and muscle dysmorphia.

Participants were 79 male collegiate athletes who were randomized to the MABP (n=39) or an assessment-only control condition (n=40). All participants completed psychometrically validated measures at three time points baseline, post-treatment (3 weeks after baseline for the control condition), and 1-month follow-up.

Hierarchical Linear Modeling assessed differences between conditions across time. Interaction effects revealed that participation in the MABP improved satisfaction with specific body parts and reduced drive for muscularity and body-ideal internalization at post-treatment compared to a control group. Athletes in the MABP also reported incrgs suggest that male college athletes who attended a 3-session group intervention based on a well-established program for college women experienced an increase in satisfaction with specific body areas and a reduction in some eating disorder risk factors (e.g., drive for muscularity, supplement use, and body-ideal internalization) compared to a control group.In many regions across Africa, agriculture is largely based on low-input and small-holder farming systems that use little inorganic fertilisers and have limited access to irrigation and mechanisation. Improving agricultural practices and developing new cultivars adapted to these environments, where production already suffers from climate change, is a major priority for food security. Here, we illustrate how breeding for specific root traits could improve crop resilience in Africa using three case studies covering very contrasting low-input agroecosystems. We first review how greater basal root whorl number and longer and denser root hairs increased P acquisition efficiency and yield in common bean in South East Africa. We then discuss how water-saving strategies, root hair density and deep root growth could be targeted to improve sorghum and pearl millet yield in West Africa. Finally, we evaluate how breeding for denser root systems in the topsoil and interactions with arbuscular mycorrhizal fungi could be mobilised to optimise water-saving alternate wetting and drying practices in West African rice agroecosystems. We conclude with a discussion on how to evaluate the utility of root traits and how to make root trait selection feasible for breeders so that improved varieties can be made available to farmers through participatory approaches.
To study the effect of inflammatory markers in blood such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) on the Gleason score (GS) changes in patients with prostate cancer (PCa) after radical prostatectomy (RP), we conducted this study.

From November 2012 to September 2021, a total of 237 patients underwent RP at our institution. Blood samples from all patients were collected within 1week before surgery. Preoperative clinical characteristics include age, serum IL-6 and TNF-α, neutrophil-to-lymphocyte ratio, C-reactive protein, the platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, systemic immune-inflammation index, the prostate imaging reporting and data system (PI-RADS) score, prostate-specific antigen, and biopsy GS were assessed. Univariate and multivariate logistic regression analyzes were used to determine the risk factors of GS changes after RP. The efficiency of this prediction model was identified with the area under the curveof the receiver operating characteristic curvTNF-α level is positively correlated with GS upgraded in PCa patients. High expression of serum IL-6 level is negatively correlated with GS upgraded in PCa patients and positively related with GS downgraded.Down Syndrome or trisomy 21 (T21) is a genetic condition caused by the presence of an extra chromosome in pair 21 and is related to a high prevalence of agenesis of permanent teeth and periodontal alterations that may be associated to the loss of permanent teeth at early ages. With the increase in life expectancy of people with T21 in the last decades, it is necessary to expand the knowledge to offer possibilities of treatment with dental implants, aiming to serve this aging population.
The aim of this article is to report a surgical procedure of sinus lift to enable the installation of dental implants in the posterior region of the maxilla.

A 50 year-old patient with T21 was rehabilitated with implants, simultaneously with sinus lift surgery, by the lateral window technique, using xenogenous bone graft and fibrin-rich plasma. After 1 year, the patient was rehabilitated with prosthetics on implants.

The feasibility of this technique in patients with Down syndrome could be observed, after 3 years of follow up, with favorable clinical results.

These conserved membrane-adaptive processes have been studied extensively. However, key concepts of membrane biology linked to regulation of lipid composition including homeoviscous adaptation maintaining stable levels of membrane fluidity, and gel-fluid phase separation resulting in domain formation, heavily rely upon in vitro studies with model membranes or lipid extracts. Using the bacterial model organisms Escherichia coli and Bacillus subtilis, we now show that inadequate in vivo membrane fluidity interferes with essential complex cellular processes including cytokinesis, envelope expansion, chromosome replication/segregation and maintenance of membrane potential. Furthermore, we demonstrate that very low membrane fluidity is indeed capable of triggering large-scale lipid phase separation and protein segregation in intact, protein-crowded membranes of living cells; a process that coincides with the minimal level of fluidity capable of supporting growth. Importantly, the in vivo lipid phase separation is not associated with a breakdown of the membrane diffusion barrier function, thus explaining why the phase separation process induced by low fluidity is biologically reversible.Epigenetic regulation is necessary for optimal organism development and preservation of gene expression profiles in the cell. In plants, the trimethylation of histone H3 lysine 27 (H3K27me3) is a silencing epigenetic mark relevant for developmental transitions like flowering. The floral transition is a key agronomic trait; however, the epigenetic mechanisms of flowering time regulation in crops remain poorly understood. Here we study the Jumonji H3K27me3 demethylases BraA.REF6 and BraA.ELF6 in Brassica rapa. Phenotypic characterization of novel mutant lines and genome-wide H3K27me3 chromatin immunoprecipitation and transcriptomic analyses indicated that BraA.REF6 plays a greater role than BraA.ELF6 in fine-tuning H3K27me3 levels. In addition, we found that braA.elf6 mutants were early flowering due to high H3K27me3 levels at B. rapa homologs of the floral repressor FLC. Unlike mutations in Arabidopsis thaliana, braA.ref6 mutants were late flowering without altering the expression of B. rapa FLC genes. Remarkably, we found that BraA.
