In addition, gracillin inhibits IL6-induced nuclear translocation of P-STAT3. Gracillin shows potent efficacy against CRC by inhibiting the STAT3 pathway. It should be further explored as a unique STAT3 inhibitor for the treatment of CRC.Ovarian response of collared peccaries (Pecari tajacu), after hormonal stimulation with gonadotropin association (eCG/hCG), was accessed by both gene expression and follicular development. Thus, collared peccaries (n = 8) were treated with the dose used for sows (swine dose, SWD) or with dose adjusted for peccary's weight (allometric dose, ALD). The gene expression of receptors was evaluated for both gonadotropins (FSHR and LHCGR) and growth factors (proteins codified by TGFβR-1, BMPR1-A and BMPR2 genes) in antral follicles, cortex and corpora haemorrhagica (CH). Five days after gonadotropin injection, all females presented CH. The ovulation rate was similar (p > .05) between SWD (4.00 ± 1.17) and ALD (2.50 ± 0.43) group. The total number of follicles per animal and amounts of small (5 mm) follicles was similar among groups. However, SWD produced large follicles heavier than ALD group, as accessed by weight of follicular wall biopsies. Ovarian follicles expressed both gonadotropin and growth factor receptors at levels which are independent from gonadotropin dose. In conclusion, the two gonadotropin doses (SWD and ALD) can be used for ovarian stimulation of collared peccary. Additionally, FSH and growth factors (TGFβR-1, BMPR1-A and BMPR2) receptors are more expressed in the early follicle development, while LH receptor seems to be more important in the final of follicular growth.Stroke is a lethal cerebral disease with severe sequelae and high mortality. Microglia, the main immune cell in the cerebrum, possess therapeutic potential for strokes as its specific anti-inflammatory phenotype can reduce inflammation and promote neuron regeneration. MMAE However, the on-demand anti-inflammatory polarization of microglia at the stroke site is uncontrollable for therapeutic application. Here, we develop a platelet hybrid microglia platform which can specifically polarize to the anti-inflammatory phenotype by ultrasound irradiation for targeted cerebrum repair after stroke. The engineered microglia have strong adherence to the injured cerebral vessels with platelet membrane fusion and realize on-demand anti-inflammatory polarization with ultrasound-responsive IL-4 liposome decoration. The intravenously injected microglia platform showed anti-inflammatory polarization at the stroke site with insonation, and accelerated the M2-type polarization of endogenous microglia for long-term stroke recovery. Satisfied prognoses were achieved with reduced apoptosis, promoted neurogenesis, and functional recovery, indicating the implications of the microglia platform for stroke therapy.Hybridization increases genetic variation, hence hybrid species may have greater evolutionary potential once their admixed genomes have stabilized and incompatibilities have been purged. Yet, little is known about how such hybrid lineages evolve at the genomic level following their formation, in particular their adaptive potential. Here we investigate how the Italian sparrow (Passer italiae), a homoploid hybrid species, has evolved and locally adapted to its variable environment. link2 Using restriction site-associated DNA sequencing (RAD-seq) on several populations across the Italian peninsula, we evaluate how genomic constraints and novel genetic variation have influenced population divergence and adaptation. We show that population divergence within this hybrid species has evolved in response to climatic variation, suggesting ongoing local adaptation. As found previously in other nonhybrid species, climatic differences appear to increase population differentiation. We also report strong population divergence in a gene known to affect beak morphology. Most of the strongly divergent loci among Italian sparrow populations do not seem to be differentiated between its parent species, the house and Spanish sparrows. Unlike in the hybrid, population divergence within each of the parental taxa has occurred mostly at loci with high allele frequency difference between the parental species, suggesting that novel combinations of parental alleles in the hybrid have not necessarily enhanced its evolutionary potential. Rather, our study suggests that constraints linked to incompatibilities may have restricted the evolution of this admixed genome, both during and after hybrid species formation.
To discover the level of evidence-based practice competency of Spanish nurses, to develop a scale of the EBP-COQ-Prof© and to analyse the influence of different variables on the level of competency.
The evidence-based practice competency has previously been assessed using a wide variety of instruments, although these have methodological limitations and lack associated scales that allow for the interpretation of the score obtained.
Observational, cross-sectional, national study. Using an online questionnaire, data were obtained between January and March 2020 from nurses working in the National Health System. An ANOVA was performed along with multiple regression analyses. The T-score and percentiles were calculated to obtain the scale of the EBP-COQ-Prof©.
2,942 nurses participated. The score for the evidence-based practice competency was 130.29 (standard deviation 17.55). The multiple regression analysis showed a model comprised of 8 variables that explained 33% of the variance.
The Spanish nurses have a moderate level of evidence-based practice competency. The scale classifies the subjects into 3 levels low, moderate and high competency.
The scale proposed for the EBP-COQ-Prof© could be utilized to facilitate the diagnosis of evidence-based practice competency, and to monitor and plan individual and collective strategies to improve this competency.

Cardiac tumors are rare conditions. The vast majority of them are benign yet they may lead to serious complications. Complete surgical resection is the gold standard treatment and should be performed as soon as the diagnosis is made. Median sternotomy (MS) is the standard approach and provides excellent early outcomes and durable results at follow-up. However, minimally invasive (MI) is gaining popularity and its role in the treatment of cardiac tumors needs further clarification.
A systematic literature review identified 12 candidate studies; of these, 11 met the meta-analysis criteria. We analyzed outcomes of 653 subjects (294 MI and 359 MS) with random effects modeling. Each study was assessed for heterogeneity. The primary endpoints were mortality at follow-up and tumor relapse. Secondary endpoints included relevant intraoperative and postoperative outcomes; tumor size was also considered.
There were no significant between-group differences in terms of late mortality (incidence rate ratio [IRR] MI vs. MS, 0.98 [95% confidence interval [CI] 0.25-3.82], p = .98). Few relapses (IRR 1.13; CI 0.26-4.88; p = .87) and redo surgery (IRR 1.92; 95% CI 0.39-9.53; p = .42) were observed in both groups; MI approach resulted in prolonged operation time but that did not influence the clinical outcomes. Tumor size did not significantly differ between groups.
Both MI and MS are associated with excellent early and late outcomes with acceptable survival rate and low incidence of recurrences. This study confirms that cardiac tumor may be approached safely and radically with a MI approach.

The delivery of cardiovascular care has been stifled during the pandemic to adhere to infection control measures as a way of protecting patients and the workforce at large. This cautious approach has been protective since individuals with COVID-19 and cardiovascular disease are anticipated to have poorer outcomes and an increased risk of death. The combination of postponing elective cardiovascular surgeries, reduced acute care and long-term cardiac damage directly resulting from COVID-19 will likely have increased the demand for cardiac care, particularly from patients presenting with more severe symptoms. The combination of increased demand and inhibited supply will likely result in huge backlog of unmet patients' needs. The novelty, virulence and infectivity of severe acute respiratory syndrome coronavirus 2 has caused substantial morbidity and mortality, thus necessitating modifications to the UK government's healthcare strategy. link3 Without improving cost efficiency, the UK's ageing population will likely need an increasing spend on cardiac surgery simply to maintain the same level of service. However, the government's short-term increase in spending is unsustainable especially in the face of ongoing economic uncertainty. This means that the long-term impact of COVID-19 will only increase the need to find innovative ways of delivering equivalent or superior cardiac care at a reduced unit cost.
We investigated the effect of preoperative renal dysfunction on postoperative outcomes in patients undergoing elective isolated total arch replacement (TAR) with mild hypothermic lower body circulatory arrest with antegrade selective cerebral perfusion (SCP).
One hundred and forty-four patients who had undergone elective isolated TAR between January 2002 and December 2019 were retrospectively analyzed. Patients were divided into two groups according to whether their preoperative estimated glomerular filtration rate (eGFR) was lower than or higher than 60 ml/min/1.73 m
. We compared perioperative data and mid-term outcomes after adjusting for patients' baseline characteristics using weighted logistic regression analysis and inverse probability of treatment weighting.
More patients underwent postoperative stroke in the chronic kidney disease group compared with the normal group (2.8% vs. 0%, respectively; p = .049). Overall 30-day mortality and hospital mortality were 0% in both groups, and there was no significant difference in overall survival between the two groups (log-rank test, p = .129). Multivariate Cox proportional hazard analysis showed that eGFR < 60 ml/min/1.73 m
was not an independent predictor (hazard ratio 1.636, 95% confidence interval 0.829-3.231; p = .156).
Preoperative eGFR <60 ml/min/1.73 m
was not associated with worse outcomes after elective isolated TAR with mild hypothermic lower body circulatory arrest with antegrade SCP.
Preoperative eGFR less then 60 ml/min/1.73 m2 was not associated with worse outcomes after elective isolated TAR with mild hypothermic lower body circulatory arrest with antegrade SCP.Specific force capacities might be a limiting factor for alpine skiing performance, yet there is little consensus on the capabilities in question, and whether they differ between disciplines. We aimed to test discipline (speed and technical) and performance (event-specific world standing) effects on lower limb force-production qualities. National-level skiers (N = 31) performed loaded squat jumps and isometric mid-thigh pulls to detect dynamic force output at extremely low and high velocities and maximum isometric force and rate of force development, respectively. Discipline differences were assessed via a general linear model including performance and allowing for interaction effects, with performance associations further characterized via distinct Pearson's correlations. Jump height did not differentiate disciplines, with absolute power slightly higher in speed athletes (F(1,27) = 4.42, P = .045, ω2 = 0.10), and neither variables were related to performance. Speed athletes possessed greater dynamic force at low velocities (F0 ; F(1,27) = 13.
