Using the multiple sequentially Markov coalescent model, we inferred the demographic history of the two pathogen subpopulations over the last 0.5 Myr. We show that both populations experienced a recent strong bottleneck starting around 10,000 years ago, coinciding with the assumed time of maize domestication. Although the genome average genetic diversity is low compared with other fungal pathogens, we estimated that the rate of nonsynonymous adaptive substitutions is three times higher in genes located within virulence clusters compared with nonclustered genes, including nonclustered effector genes. These results highlight the role that these singular genomic regions play in the evolution of this pathogen.Exosomes are involved in the pathophysiology of neuropsychiatric diseases, but the role of exosomes in schizophrenia (SCZ) is unclear. Here, we demonstrate that transplantation of serum exosomes from SCZ patients into mice caused behavioral abnormalities such as deficits in prepulse inhibition and sociability, hyperactivity, and anxiogenesis. A comparative bioinformatics analysis suggested shared and distinct differentially expressed genes (DEGs) and enriched molecular pathways in the brains of SCZ exosome-recipient mice, methylazoxymethanol acetate-treated rats, and SCZ patients, which correlates evidence of altered prefrontal-hippocampal functional coherence in SCZ. A large proportion of SCZ-relevant DEGs in the exosome-recipient mice were targets of DE exosomal miRNAs in SCZ patients. Furthermore, we identified 20 hub genes for SCZ risk genes, including BDNF and NRG1, which were DE miRNA targets in SCZ. Collectively, our study suggests that SCZ exosome transplantation caused SCZ-relevant behaviors in mice, and epigenetic regulation may contribute to the phenotypes in the SCZ exosome-recipient mice. Our results may provide a potential animal model and novel therapeutic targets for SCZ.

Intravenous immunoglobulin (IVIG) resistance and coronary artery lesions (CALs) prediction are pivotal topic of interests in Kawasaki disease (KD). However, data on the predictive value of lipid profile for both IVIG resistance and CALs are limited.

To investigate the predictive validity of lipid profile for IVIG resistance and CALs in KD.

Prospective cohort study.

West China Second University Hospital.

363 KD patients were divided into the initial IVIG-resistant group and initial IVIG-responsive group; repeated IVIG-resistant group and repeated IVIG-responsive group; CAL+ group and CAL- group.

Validity of lipid profile in predicting IVIG resistance and CALs.

TG was significantly higher whereas TC, HDL-C, LDL-C as well as Apo A were significantly lower in initial IVIG-resistant subjects, with cut-off values of 1.625 mmol/L, 3.255 mmol/L, 0.475 mmol/L, and 1.965 mmol/L and 0.665g/L, yielding sensitivities of 52%, 70%, 52%, 61%, 50%, and specificities of 68%, 53%, 78%, 71%, 81%, respectively. TC, LDL-C, and Apo A levels were significantly lower in repeated IVIG-resistant subjects, with cut-off values of 3.20 mmol/L, 1.78 mmol/L, 0.605g/L, producing sensitivities of 91%, 70%, 57% and specificities of 55%, 67%, 70%, respectively. Apo-A level was significantly lower in the CAL group, with cut-off value of 0.805g/L, yielding sensitivity of 66% and specificity of 54%.

Lipid profiles were significantly dysregulated in KD patients suffering IVIG resistance and CALs. Some of them, such as LDL-c and Apo-A, could serve as complementary laboratory markers for predicting both IVIG resistance and CALs.

Eukaryotes use an equivalent system of archaeal origin to deliver proteins into the endoplasmic reticulum, whereas a bacteria-derived SRP and FtsY function in the plastid. Here we report on the presence of homologs of the bacterial Ffh and FtsY proteins in various unrelated plastid-lacking unicellular eukaryotes, namely Heterolobosea, Alveida, Goniomonas, and Hemimastigophora. The monophyly of novel eukaryotic Ffh and FtsY groups, predicted mitochondrial localization experimentally confirmed for Naegleria gruberi, and a strong alphaproteobacterial affinity of the Ffh group, collectively suggest they constitute parts of an ancestral mitochondrial signal peptide-based protein-targeting system inherited from the last eukaryotic common ancestor, but lost from the majority of extant eukaryotes. The ability of putative signal peptides, predicted in a subset of mitochondrial-encoded N. gruberi proteins, to target a reporter fluorescent protein into the endoplasmic reticulum of Trypanosoma brucei, likely through their interaction with the cytosolic SRP, provided further support for this notion. We also illustrate that known mitochondrial ribosome-interacting proteins implicated in membrane protein targeting in opisthokonts (Mba1, Mdm38, and Mrx15) are broadly conserved in eukaryotes and non-redundant with the mitochondrial SRP system. Finally, we identified a novel mitochondrial protein (MAP67) present in diverse eukaryotes and related to the signal peptide-binding domain of Ffh, which may well be a hitherto unrecognized component of the mitochondrial membrane protein-targeting machinery.

There are only few data on the impact of smoking and smoking cessation on outcome of patients treated with allogeneic hematopoietic stem cell transplantation, a well established therapy for hematologic malignancies.

In a retrospective cohort study design we examined impact of smoking and smoking cessation on survival among 309 eligible consecutive adults who underwent allogeneic hematopoietic stem cell transplantation using reduced-intensity (n=179) or myeloablative (n=130) conditioning between 1999 and 2018.

Smoking and was independently associated with increased mortality with a five-year overall survival of 25% in current smokers vs. 53% in never smokers vs. 48% in past smokers. Never smokers lived significantly longer (HR 2.00, 95%CI 1.19-3.35, p=0.008) and had a better event-free survival (HR 2.11, 95%CI 1.27-3.49, p=0.004) than current smokers. mTOR tumor In the long run never smokers also lived significantly longer than past smokers (HR 1.45, 95%CI 1.16-1.81, p = 0.001). Patients who quit smoking prior to allogeneic hematopoietic stem cell transplantation showed a tendency towards increased survival compared to those continued smoking (HR 1.
