We retrospectively compared the outcomes of 20 patients receiving Venetoclax + low-dose Cytarabine + Actinomycin D (ACTIVE) with 29 patients receiving FLAG-Ida as salvage therapy for relapsed or refractory AML (R/R AML) after alloSCT. The groups were statistically balanced according to age, performance status, cytogenetics, and previous treatment. The overall response rate (CR + CRp + MLFS) of ACTIVE was 75% (15/20) in comparison to 66% (19/29) in the FLAG-Ida group (p = 0.542). The cumulative CR + CRp rate was significantly higher in the ACTIVE group compared to FLAG-Ida (70% (14/20) vs. 34% (10/29), respectively, p = 0.02). All three patients failing previous Venetoclax therapy and five out of seven patients with previous FLAG-Ida exposure achieved a CR/CRp after ACTIVE induction. ACTIVE patients survived longer compared to FLAG-Ida patients (13.1 vs. 5.1 months, respectively, p = 0.032). The treatment-related mortality was 0% in the ACTIVE group and 34% (10/29) in the FLAG-Ida patients (p = 0.003). The cumulative incidence of relapse did not differ between the two treatment groups. ACTIVE appears to have comparable antileukemic activity and lower toxicity compared to FLAG-Ida resulting in improved survival. Patients with Venetoclax or FLAG-Ida exposure responded to ACTIVE.
  Retrospective study.
 
  We aimed to characterize the convergent disruptions of the structural connectivity based on network modeling technique (i.e., graph theory) to identify significant changes in network organization/reorganization between uninjured and chronic spinal cord injury (SCI) participants.
 
  USA.
 
  Ten adult participants including 4 with chronic SCI and 6 uninjured were scanned using a multi-shell diffusion imaging on a 3.0 T MR scanner. Whole brain structural connectivity matrix was estimated by performing the quantification of the number of white matter fibers (called edges) connecting each possible pair of brain region (called nodes). Brain regions were defined according to Desikan-Killiany cortical atlas. Using connectivity matrix, connectivity strength as well as six different graph theoretical measurements were computed for each participant. They include (1) global efficiency; (2) local efficiency; (3) degree; (4) betweenness centrality; (5) average shortest length and (6) clustering coeffn affected after SCI.
  Adolescent overweight and obesity are well documented in high-income countries (HICs). They are also emerging as a global public health concern in low-and middle-income countries (LMICs), yet there is a lack of reliable, national-level data to inform policies and interventions. This study aimed to estimate the prevalence of overweight and obesity and assess associated lifestyle risk factors amongst school-going adolescents in LMICs as well as HICs.
 
  A total of 282,213 samples were drawn from 89 LMICs and HICs in the 'latest Global School-based Student Health Survey' of school children, aged 11-17 years, during 2003 to 2015, in the six World Health Organisation (WHO) regions. The prevalence of adolescent overweight and obesity were estimated using the WHO BMI-for-age growth standards. A multinomial logistic regression model was employed to estimate the adjusted (age and sex) association of food patterns, physical activity, and sedentary behaviours with adolescent overweight and obesity.
 
  The pooled prevaleased obesity prevention that promotes environmental and policy changes related to healthy dietary practices and active living are urgently needed to curb the trend.
 Adolescent overweight and obesity represent a global public health problem and can possibly track into adult weight status and morbidity. School-based obesity prevention that promotes environmental and policy changes related to healthy dietary practices and active living are urgently needed to curb the trend.Parkinson's disease (PD), one of the most common neurodegenerative disorders, is characterized by progressive neurodegeneration of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc). DJ-1 acts essential roles in neuronal protection and anti-neuroinflammatory response, and its loss of function is tightly associated with a familial recessive form of PD. However, the molecular mechanism of DJ-1 involved in neuroinflammation is largely unclear. Here, we found that wild-type DJ-1, rather than the pathogenic L166P mutant DJ-1, directly binds to the subunit p65 of nuclear factor-κB (NF-κB) in the cytoplasm, and loss of DJ-1 promotes p65 nuclear translocation by facilitating the dissociation between p65 and NF-κB inhibitor α (IκBα). DJ-1 knockout (DJ-1-/-) mice exhibit more microglial activation compared with wild-type littermate controls, especially in response to lipopolysaccharide (LPS) treatment. In cellular models, knockdown of DJ-1 significantly upregulates the gene expression and increases the release of LPS-treated inflammatory cytokines in primary microglia and BV2 cells.  https://www.selleckchem.com/products/pu-h71.html  Furthermore, DJ-1 deficiency in microglia significantly enhances the neuronal toxicity in response to LPS stimulus. In addition, pharmacological blockage of NF-κB nuclear translocation by SN-50 prevents microglial activation and alleviates the damage of DA neurons induced by microglial DJ-1 deficiency in vivo and in vitro. Thus, our data illustrate a novel mechanism by which DJ-1 facilitates the interaction between IκBα and p65 by binding to p65 in microglia, and thus repressing microglial activation and exhibiting the protection of DA neurons from neuroinflammation-mediated injury in PD.Human iPSC lines represent a powerful translational model of tauopathies. We have recently described a pathophysiological phenotype of neuronal excitability of human cells derived from the patients with familial frontotemporal dementia and parkinsonism (FTDP-17) caused by the MAPT 10+16 splice-site mutation. This mutation leads to the increased splicing of 4R tau isoforms. However, the role of different isoforms of tau protein in initiating neuronal dementia-related dysfunction, and the causality between the MAPT 10+16 mutation and altered neuronal activity have remained unclear. Here, we employed genetically engineered cells, in which the IVS10+16 mutation was introduced into healthy donor iPSCs to increase the expression of 4R tau isoform in exon 10, aiming to explore key physiological traits of iPSC-derived MAPT IVS10+16 neurons using patch-clamp electrophysiology and multiphoton fluorescent imaging techniques. We found that during late in vitro neurogenesis (from ~180 to 230 days) iPSC-derived cortical neurons of the control group (parental wild-type tau) exhibited membrane properties compatible with "mature" neurons.
