Previous studies have shown that the perception of neutral emotion stimuli can be negative rather than absolutely neutral. In the current study, we examined the negative bias of both neutral faces and scenes, cross-culturally between East Asians (e.g. Koreans) and Caucasian Americans. In all experiments, participants performed a Go/No-go task, by either executing or withholding a response toward neutral stimuli presented in the context of positive or negative stimuli. Differentiating neutral stimuli from negative stimuli was less accurate, measured in d', than doing so from positive stimuli. This negative bias was evident with both faces (Experiments 1 and 2) and scenes (Experiment 3). In all experiments, while both ethnic groups demonstrated significant negative biases, there was a subtle modulation of the bias by cultural background. For example, for Korean faces and IAPS scenes, Koreans showed a mitigated negative bias and Caucasian Americans demonstrated a greater negative bias. However, for Caucasian faces, bias was comparable between the two groups. With the possibility of cultural modulation, the prevalent negative bias of neutral emotion questions the validity of the neutrality assumption of the neutral emotion. The study discusses the necessity of methodological and theoretical reconsiderations for the utilisation of neutral emotion stimuli.Background Several studies have investigated two single nucleotide polymorphisms (SNPs) (rs4986790 and rs4986791) of toll-like receptor 4 (TLR4) and age-related macular degeneration (AMD) susceptibility. However, their results varied. Here, we performed a systematic review and meta-analysis to investigate the association between these two SNPs and AMD susceptibility.Materials and Methods We searched the PubMed and Web of Science databases for articles indexed up to July 20, 2019. Studies investigating the association between TLR4 polymorphisms rs4986790 (Asp299Gly) and rs4986791 (Thr399Ile) and AMD susceptibility were included in this systematic review. The results of the included studies were pooled with allele contrast, recessive, dominant and overdominant models. The quality of the included studies was assessed using the Newcastle-Ottawa Scale. Egger's test was used to evaluate publication bias.Results Six studies with 9 cohorts were included in this systematic review and meta-analysis. The recessive and overdominant models showed that rs4986790 was significantly associated with AMD susceptibility, with odds ratios (ORs) of 0.73 and 1.41, respectively. By contrast, rs4986791 was not associated with AMD susceptibility. Endoxifen Estrogen antagonist No publication bias was observed for either rs4986791 or rs4986790.Conclusion The current evidence supports the hypothesis that rs4986790 but not rs4986791 is associated with AMD susceptibility.Infection-induced acute encephalopathies (IIAEs) are a group of neurologic disorders caused post infection. They are of 8 types, 6 of which are herpes specific, whereas IIAE3 and IIAE4 can be triggered by infections additional to herpeslike influenza, enterovirus, etc. IIAE3 is also known as acute necrotizing encephalopathy type 1, which is a rare type of encephalopathy that occurs following an infection in infancy or early childhood. Symptoms include fever, cough, congestion, vomiting, and diarrhea followed by seizures, hallucination, ataxia, and abnormal muscle tone, and sometimes it leads to untimely death. Here, we describe a familial case where 3 siblings were clinically diagnosed with acute necrotizing encephalopathy 1. Genetic testing revealed 2 heterozygous variations RANBP2 c.5249C>G, p.P1750 R, and CPT2 c.365C>T, p.S122F. Variants in RANBP2 and CPT2 have been individually known to be associated with IIAE3 and IIAE4, respectively. Segregation analysis revealed that the RANBP2 variant was inherited from the father and the CPT2 variant from the mother. This case qualifies to be the first of its kind where digenic inheritance (ie, DNA sequence variants in 2 genes are required for the pathogenic phenotypes) appears to cause a lethal class of acute necrotizing encephalopathy.Objective The aim of our study is to investigate the relationship between podocyte autophagy and apoptosis induced by Puromycin Aminonucleoside (PAN) and to clarify its mechanism.Methods Podocytes were cultured in vitro. The apoptosis rates of each group were detected using flow cytometry. The expression of LC3-II protein and changes in distribution were detected through laser scanning confocal microscope, and the western blot protocol was employed for detection of protein expression of LC3-II. The autophagosomes were detected by transmission electron microscopy.Results In this study, We found that autophagosome increased followed by apoptosis after podocyte injury. Furthermore, we conformed that the activation of autophagy could inhibit the apoptosis to alleviate the injury of podocyte at an early stage.Conclusions Autophagy occurred earlier before apoptosis and autophagy mediated podocyte apoptosis induced by PAN. These findings indicate that autophagy may become a novel therapeutic target for the treatment of podocyte injury and proteinuria in the future.At least 9 neuroscientists immigrated from Nazi Europe to Illinois to escape tyranny and attempt to re-establish their careers. Some work has been published in print on eponymous neuroscientist Adolf Wallenberg, as well as 2 others but not on Ernst Haase, Frederick Hiller, Erich Liebert, Bruno Volk, Heinz (Henry) von Witzleben, or Gerhard Pisk. Before leaving Germany or Austria, these downtrodden specialists were dismissed from long-held posts sometimes for trumped-up charges, stripped of their financial security, and forced to leave relatives behind. At least 1 left only for personal and political, but not because of racial, reasons. Illinois, in exemplary fashion, welcomed these unfortunate survivors more than many other states because of limited licensing requirements, numerous opportunities at state hospitals, and special internship programs. Some of them successfully continued their research agendas and published, taught neurology students and trainees, and added to the expansion of neurologic care in Illinois or elsewhere, but most of them took years to reacquire the academic rank they lost and never regained their career momentum.
