The results showed that the right target was favoured more often when solving additions than when solving subtractions both in the French- (n = 31) and Arabic-speaking (n = 25) groups. This was true even in Arabic-speaking participants whose preference for ordering of various series of numerical and non-numerical stimuli went from right to left (n = 10). These results indicate that SNAs in mental arithmetic cannot be explained by the direction of reading/writing habits and call for a reconsideration of current models to acknowledge the pervasive role of biological factors in SNAs in adults.This study aimed to evaluate the effect of sodium caseinate added into freezing extender on the sperm parameters of cryopreserved bull semen and in vitro and in vivo fertility. One ejaculate of 30 bulls was used and processed using Botu-Bov (Botupharma, Botucatu, Brazil) with the addition of 20% egg yolk (EY) or 15% egg yolk with 2% sodium caseinate (EY + SC), subsequently submitted to freezing. Semen from both groups were evaluated immediately after thawing (T0) and after thermic stress at 37 °C for 90 min (T90), for sperm kinetics, by CASA method, and plasma membrane integrity (PMI), superoxide (O2-) concentration and high mitochondrial potential (HMP) by flow cytometry. In vitro fertilization (IVF) was performed to assess embryo cleavage rate on day 3, and blastocyst rate on day 8. The in vivo fertility test was performed using fixed-time artificial insemination (FTAI). In sperm evaluation, trajectory velocity, linear velocity, curvilinear velocity, and lateral head movement were higher (P 0.05) between the groups at T0. For O2- and HMP, the values were lower (P less then 0.05) in EY + SC group in both moments; furthermore, EY + SC showed higher cleavage and blastocyst rates in IVF. Likewise, pregnancy rates by FTAI were higher (P less then 0.05) in the EY + SC group. In conclusion, the addition of sodium caseinate into freezing extender improves sperm parameters of frozen-thawed bull semen and fertility rates on during in vitro and in vivo tests.Germinal vesicle oocytes obtained by ovum pick-up (OPU) on a random day are heterogeneous in terms of chromatin maturity, and those with an intermediate degree of chromatin compaction present higher developmental competence. We previously developed a synchronization protocol combining follicle aspiration and FSH treatment capable of increasing the percentage of oocytes with intermediate chromatin compaction (classified as GV2 oocytes; within progressive stages of chromatin compaction ranging from GV0 to GV3) at the time of OPU. In this study, we tested the capacity of a similar protocol to synchronize oocyte chromatin maturity before OPU, as well as to improve the efficacy of in vitro embryo production (IVP) in Holstein cows. In the first experiment, eight non-lactating Holstein cows were subjected to the D5/4FSH, during which all follicles larger than 2 mm were aspirated and a progesterone intravaginal device was inserted on a random day (day 0). Subsequently, four IM injections of FSH (Folltropin; 40/40/20/embryo in vitro production in cattle.The histone variant H3.3 is an important maternal factor in fertilization of oocytes and reprogramming of somatic cell nuclear transfer (SCNT) embryos. As a crucial replacement histone, maternal H3.3 is involved in chromatin remodeling and zygote genome activation. Litte is, however, known about the replacement of H3.3 in the bovine SCNT embryos. In this study, the maternal H3.3 in mature ooplasm was labeled with HA tag and the donor cells H3.3 was labeled with Flag tag, in order to observe the replacement of H3.3 in the bovine SCNT embryos. Meanwhile, maternal H3.3 knockdown was performed by microinjecting two different interfering fragments before nucleus transfer. It was showed that the dynamic replacement between maternal- and donor nucleus-derived H3.3 was detected after SCNT. And it could be observed that the blastocyst development rate of the cloned embryos decreased from 22.3% to 8.2-10.3% (P less then 0.05), the expression of Pou5f1 and Sox2 was down-regulated and the level of H3K9me3 was increased in the interfered embryos. In summary, H3.3 replacement impacted on the process of reprogramming, including embryonic development potential, activation of pluripotency genes and epigenetic modification in bovine SCNT embryos.Cytotoxicity-guided fractionation of the MeOH extract of Helleborus lividus Aiton ex Curtis (Ranunculaceae) resulted in the isolation of five undescribed bufadienolide glycosides and two undescribed bufadienolides, along with three known compounds. Their structures were determined by detailed spectroscopic analysis and hydrolysis studies. The isolated compounds showed cytotoxicity against HL-60 human leukemia cells and A549 human lung adenocarcinoma cells, with IC50 values ranging from 2.20 ± 0.01 nM to 0.77 ± 0.01 μM. The undescribed compound 3β-[(O-β-d-glucopyranosyl-(1 → 4)-α-l-rhamnopyranosyl)oxy]-14β,16β-dihydroxy-5β-bufa-20,22-dienolide induced apoptosis in HL-60 cells via a mitochondria-dependent apoptotic pathway. The average IC50 values of bufadienolide monorhamnosides for HL-60 and A549 cells were 10-20 times lower than those for Na+/K+ ATPase, implying that they induce tumor cell death via a mechanism of action other than Na+/K+ ATPase inhibition.The first COVID-19 case in Brazil was confirmed on February 25, 2020. Partial lockdown measures came into force in the city of Rio de Janeiro, Brazil, on March 23. While CO and NO2 levels showed significant reductions, PM10 levels were only reduced in the first partial lockdown week. 1-Deoxynojirimycin purchase By contrast, ozone levels increased in all studied locations. In this study, the factors leading to this behavior were analyzed. Monitoring data obtained at two automatic monitoring stations showed higher ratios between non-methane hydrocarbons and nitrogen oxides (NMHC/NOx) during the partial lockdown (up to 37.3%). The increase in ozone concentrations during the social distancing measures could be attributed to the increase in NMHC/NOx ratios since atmospheric chemistry in Rio de Janeiro is under VOC-controlled conditions. However, the increase was higher when air masses arrived from the industrial areas, not only because of the higher NMHC/NOx ratios, but also because the reactivity of VOC was highly increased by these air masses, which are rich in aromatic compounds.Introduction There is currently no general agreement on how to best conceptualize dissociative symptoms and whether they share similar neural underpinnings across dissociative disorders. Neuroimaging data could help elucidate these questions. Objectives The objective of this review is to summarize empirical evidence for neural aberrations observed in patients suffering from dissociative symptoms. Methods A systematic literature review was conducted including patient cohorts diagnosed with primary dissociative disorders, post-traumatic stress disorder (PTSD), or borderline personality disorder. Results Results from MRI studies reporting structural (gray matter and white matter) and functional (during resting-state and task-related activation) brain aberrations were extracted and integrated. In total, 33 articles were included of which 10 pertained to voxel-based morphology, 2 to diffusion tensor imaging, 10 to resting-state fMRI, and 11 to task-related fMRI. Overall findings indicated aberrations spread across diverse brain regions, especially in the temporal and frontal cortices. Patients with dissociative identity disorder and with dissociative PTSD showed more overlap in brain activation than each group showed with depersonalization/derealization disorder. Conclusion In conjunction, the results indicate that dissociative processing cannot be localized to a few distinctive brain regions but rather corresponds to differential neural signatures depending on the symptom constellation.Background In patients with stable coronary heart disease, it is not known whether achievement of standard of care (SOC) targets in addition to evidence-based medicine (EBM) is associated with lower major adverse cardiovascular events (MACE) cardiovascular death, myocardial infarction, and stroke. Methods EBM use was recommended in the STabilisation of Atherosclerotic plaque By Initiation of darapLadIb TherapY trial. SOC targets were blood pressure (BP) less then 140/90 mm Hg and low-density lipoprotein-cholesterol (LDL-C) less then 100 mg/dL and less then 70 mg/dL. In patients with diabetes, glycosylated hemoglobin A1c (HbA1c) less then 7% and BP of less then 130/80 mm Hg were recommended. Feedback to investigators about rates of EBM and SOC was provided regularly. Results In 13,623 patients, 1-year landmark analysis assessed the association between EBM, SOC targets, and MACE during follow-up of 2.7 years (median) after adjustment in a Cox proportional hazards model. At 1 year, aspirin was prescribed in 92.5% of patients, statins in 97.2%, β-blockers in 79.0%, and angiotensin-converting enzyme inhibitors/angiotensin-II receptor blockers in 76.9%. MACE was lower with LDL-C less then 100 mg/dL (70-99 mg/dL) compared with LDL-C ≥ 100 mg/dL (hazard ratio [HR] 0.694, 95% CI 0.594-0.811) and lower with LDL-C less then 70 mg/dL compared with LDL-C less then 100 mg/dL (70-99 mg/dL) (HR 0.834, 95% CI 0.708-0.983). MACE was lower with HbA1c less then 7% compared with HbA1c ≥ 7% (HR 0.705, 95% CI 0.573-0.866). There was no effect of BP targets on MACE. Conclusions MACE was lower with LDL-C less then 100 mg/dL (70-99 mg/dL) and even lower with LDL-C less then 70 mg/dL. MACE in patients with diabetes was lower with HbA1c less then 7%. Achievement of targets is associated with improved patient outcomes.Introduction Biallelic damaging variants in ALPK3, encoding alpha-protein kinase 3, cause pediatric-onset cardiomyopathy with manifestations that are incompletely defined. Methods and results We analyzed clinical manifestations of damaging biallelic ALPK3 variants in 19 pediatric patients, including nine previously published cases. Among these, 11 loss-of-function (LoF) variants, seven compound LoF and deleterious missense variants, and one homozygous deleterious missense variant were identified. Among 18 live-born patients, 8 exhibited neonatal dilated cardiomyopathy (44.4%; 95% CI 21.5%-69.2%) that subsequently transitioned into ventricular hypertrophy. The majority of patients had extracardiac phenotypes, including contractures, scoliosis, cleft palate, and facial dysmorphisms. We observed no association between variant type or location, disease severity, and/or extracardiac manifestations. Myocardial histopathology showed focal cardiomyocyte hypertrophy, subendocardial fibroelastosis in patients under 4 yiomyopathy. Adults with ALPK3 LoF variants therefore warrant evaluations for cardiomyopathy.Lanthanum-modified bentonite (LMB) is a widely used phosphorus-inactivating agent in lakes. However, dissolved organic carbon (DOC) exists ubiquitously in lakes, and its influence on phosphate binding is still not adequately understood. Our results showed that both phosphate and DOC can be adsorbed by LMB. The Langmuir adsorption maxima of phosphate and DOC were 9.06 mg P/g and 5.31 mg C/g, respectively, generating a C/P molar ratio ∼1.5. When phosphate and DOC coexisted at this ratio, the adsorption of phosphate was not influenced by DOC and vice versa. However, the phosphate capture by LMB was significantly reduced by raising the ratio above ∼9, and the reduction was increased with increasing the ratio. Once adsorbed by LMB, phosphate was essentially not desorbed by DOC, while adsorbed DOC can be mostly liberated by phosphate. It is deemed that phosphate can interact preferentially with La on LMB. However, DOC can still be adsorbed by LMB, even after LMB was saturated with phosphate, which was attributed to (i) the high coordination capacity of La; (ii) the interaction of DOC with the hydroxyl group(s) of the adsorbed phosphate via hydrogen bonding; and (iii) the interaction of DOC with the La sites unoccupied by phosphate.
