A vortex ring generator with a piston-cylinder is developed for an experimental study of the formation, transportation, and ventilation characteristics of the VRPV. The translational velocity, volume, and fresh air ratio of the vortex rings are studied using high-speed cameras and tracer gas experiments. According to the results, the categories of the vortex ring volume in the formation stage are studied. It is observed that the velocity of the piston determines the initial translational velocity of the vortex ring, and a fitting equation is proposed to predict the evolution of the translational velocity. The deviation range of the VRPV over different distances is studied, and it is shown to be affected by interference from both the generator and the environment. Finally, the total volumes, fresh air volumes, and fresh air ratios of the VRPV are studied at different distances. The results indicate that, as a personalized ventilation system, the fresh air ratio of the VRPV is up to 159.3% higher than that of a symmetrical round jet within a 0-4 m range. This shows the excellent application potential of the VRPV for providing high-efficiency personalized ventilation with lower fresh airflow rates.This human case is the first to illustrate morphological manifestations of direction- and rate-dependent anisotropic conduction in high-resolution unipolar atrial potentials. Premature impulses induced low-amplitude, fractionated extracellular potentials with exceptionally prolonged durations in a 76-year old longstanding persistent patient with atrial fibrillation (AF), demonstrating direction-dependency of anisotropic conduction. An increased pacing frequency induced presence of similar fractionated potentials, reflecting rate-dependent anisotropy and inhomogeneous, slow conduction. Pacing with different rates and from different sites could aid in identifying nonuniform anisotropic tissue and thus the substrate of AF.Carbamazepine (CBZ), an anticonvulsant drug, is used by pregnant women and crosses the placental barrier, reaching the embryo/foetus. CBZ inhibits testicular steroidogenesis and may lead to alterations in testicular development, spermatogenesis and male fertility. The purpose of this study was to evaluate the CBZ effects on testicular parameters in the neonatal and pubertal phases, as well as the spermatic parameters of pubertal rats, originated from dams treated during different periods of the pregnancy. Pregnant rats were treated with CBZ (20 mg/kg/day; intraperitoneal route), from 12-20 gestation day (GD) (CBZ12 group) and 15-20 GD (CBZ15 group). The testicular morphometric and stereological analysis of rats aged 4 and 63 days was performed. The oestradiol and testosterone plasmatic levels, as well as spermatic parameters, were achieved at 63 days. CBZ12 group showed a reduction in testicular weight and volume at 4 days post-partum (dpp); however, there was an increase in the seminiferous cords' length of the CBZ12 and CBZ15 groups. At 63 days, the CBZ12 group showed increases of the daily sperm production and damage in the seminiferous epithelium. The results suggest that CBZ interferes with the testis development and the establishment of the spermatogenic process, which can be detected in the puberty phase.About 1-2% of European population are redheaded, meaning they synthesize more pheomelanin than eumelanin, the main melanin pigment in humans. Several mutations could be responsible for this phenotype. It has been suggested that corresponding mutations spread in Europe due to a founder effect shaped either by a relaxation of selection for dark, UV-protective phenotypes or by sexual selection in favour of rare phenotypes. In our study, we investigated the levels of vitamin D precursor 25(OH)D3 (calcidiol) and folic acid in the blood serum of 73 redheaded and 130 non-redheaded individuals. In redheaded individuals, we found higher 25(OH)D3 concentrations and approximately the same folic acid concentrations as in non-redheaded subjects. 25(OH)D3 concentrations correlated with the intensity of hair redness measured by two spectrophotometric methods and estimated by participants themselves and by independent observers. In non-redheaded individuals, 25(OH)D3 levels covaried with the amount of sun exposure and intensity of suntan while in redheaded individuals, this was not the case. It suggests that increased 25(OH)D3 levels in redheaded individuals are due to differences in physiology rather than in behaviour. We also found that folic acid levels increased with age and the intensity of baldness and decreased with the frequency of visiting tanning salons. Our results suggest that the redheaded phenotype could be an evolutionary adaptation for sufficient photosynthesis of provitamin D in conditions of low intensity of UVB radiation in central and northern parts of Europe.Background Cold-stored platelets are an attractive option for treatment of actively bleeding patients due to a reduced risk of septic complications and preserved hemostatic function compared to conventional room temperature-stored platelets. However, refrigeration causes increased platelet activation and aggregate formation. Specialized pro-resolving mediators (SPMs), cell signaling mediators biosynthesized from essential fatty acids, have been shown to modulate platelet function and activation. In this study, we sought to determine if SPMs could be used to inhibit cold-stored platelet activation. Methods Platelets were collected from healthy donors (n = 4-7) and treated with SPMs (resolvin E1 [RvE1], maresin 1 [MaR1], and resolvin D2 [RvD2]) or vehicle (VEH; 0.1% EtOH). Platelets were stored without agitation in the cold and assayed on Days 0 and 7 of storage for platelet activation levels using flow cytometry, platelet count, aggregation response using impedance aggregometry, and nucleotide content using mass spectrometry. Results Compared to VEH, SPM treatment inhibited GPIb shedding (all compounds), significantly reduced both PS exposure and activation of GPIIb/IIIa receptor (RvD2, MaR1), and preserved aggregation response to TRAP (RvD2, MaR1) after 7 days of storage. Similar to untreated cold-stored platelets, SPM-treated samples did not preserve platelet counts or block the release of P-Selectin. Nucleotide content was unaffected by SPM treatment in cold-stored platelets. Conclusions SPM treatment, particularly Mar1 and RvD2, led to reduced platelet activation and preserved platelet function after 7 days of storage in the cold. Future work is warranted to better elucidate the mechanism of action of SPMs on cold platelet function and activation.Glioblastoma is the most common malignant primary brain tumor. Overall, the prognosis for patients with this disease is poor, with a median survival of less then 2 years. There is a slight predominance in males, and incidence increases with age. The standard approach to therapy in the newly diagnosed setting includes surgery followed by concurrent radiotherapy with temozolomide and further adjuvant temozolomide. Tumor-treating fields, delivering low-intensity alternating electric fields, can also be given concurrently with adjuvant temozolomide. At recurrence, there is no standard of care; however, surgery, radiotherapy, and systemic therapy with chemotherapy or bevacizumab are all potential options, depending on the patient's circumstances. Supportive and palliative care remain important considerations throughout the disease course in the multimodality approach to management. The recently revised classification of glioblastoma based on molecular profiling, notably isocitrate dehydrogenase (IDH) mutation status, is a result of enhanced understanding of the underlying pathogenesis of disease. There is a clear need for better therapeutic options, and there have been substantial efforts exploring immunotherapy and precision oncology approaches. In contrast to other solid tumors, however, biological factors, such as the blood-brain barrier and the unique tumor and immune microenvironment, represent significant challenges in the development of novel therapies. Innovative clinical trial designs with biomarker-enrichment strategies are needed to ultimately improve the outcome of patients with glioblastoma.Objective To investigate the effect of nasal continuous positive airway pressure (NCPAP) given with nasal masks (NM) compared with binasal prongs (BNP) on the incidence of intubation within 72 hours in preterm infants (primary outcome) via meta-analysis of clinical studies. Data sources We searched for randomized clinical trials (RCTs) or quasi-RCTs in Medline, PubMed, and Web of Science from inception through 4 December 2019. Data extraction/synthesis Two independent co-authors extracting data performed the meta-analysis using a fixed-effect model to yield pooled relative risk (RR) and its 95% confidence interval (CI) for each outcome. AG-1478 in vitro We used Cochrane GRADE to evaluate the evidence quality. Results Eleven RCTs met the inclusion criteria. The meta-analysis showed NCPAP provided via NM significantly reduced the rate of intubation within 72 hours (RR, 0.72; 95% CI, 0.58-0.90; nine studies; GRADE-moderate) and nasal trauma (RR, 0.64; 95% CI, 0.55-0.74; GRADE-low) compared with NCPAP provided via BNP. Also, NCPAP via NM significantly reduced surfactant treatment (RR, 0.85; 95% CI, 0.74-0.97; GRADE-very low) and bronchopulmonary dysplasia (RR, 0.47; 95% CI, 0.23-0.95; GRADE-low) compared with BNP in a setting where NCPAP was used as the primary support in respiratory distress syndrome. No statistically significant differences were noted between groups in secondary outcomes except increased NCPAP duration when NCPAP given with NM compared with BNP (mean difference [days], 1.78; 95% CI, 1.67-1.89; GRADE-low). Conclusion Among premature infants, NCPAP provided with NM is more effective in preventing intubation and mechanical ventilation within 72 hours of initiating the support compared with NCPAP provided with BNP.Based on the antiinflammatory properties of garlic, current study was conducted to evaluate the garlic supplement effects on serum levels of some inflammatory biomarkers, clinical symptoms, and fatigue in women with active rheumatoid arthritis. In this randomized, double-blind, placebo-controlled trial study, 70 women with RA were randomly divided into two groups The intervention group was supplemented with 1,000 mg of garlic, and the control group received placebo for 8 weeks. At baseline and at the end of the study, clinical symptoms, fatigue, serum level of C-reactive protein (CRP), tumor necrosis factor-a (TNF-a), and erythrocyte sedimentation rate (ESR) were determined. After intervention, serum levels of CRP (p = .018) and TNF-a (p less then .001) decreased significantly in the garlic group as compared with the placebo group. Also, pain intensity, tender joint count, disease activity score (DAS-28), and fatigue were significantly decreased in the intervention group compared with the control group (p less then .
