Similarly, axonal and other neuronal injuries in the HPC+MCAO group were also ameliorated. In the in vitro experiments, mild HPC significantly enhanced the viability of NSCs, promoted the migration of differentiated cells, and reduced apoptosis.
Our results showed that HPC significantly promotes neurogenesis after MCAO and ameliorates neuronal injury.

Dichloroacetic acid (DCA), a by-product of disinfection in drinking water, is a multiple organ carcinogen in humans and animals. Still, little research on its neurotoxicity and its underlying mechanism has not been elucidated.
Sprague Dawley rats were intragastrically treated with DCA at 10, 30, 90mg/kg body weight from pregnancy till delivery. At eight weeks of age of pups, we assessed cognitive performance using the standard behavioral tests. And the hippocampus structure and ultrastructure were evaluated using light and electron microscope. The oxidative stress indicators and neuroinflammation factors were measured with the corresponding kits. The mRNA and protein of synaptic factors were detected using RT-PCR and Western blot.
The results indicated that maternal weight gain and offspring birthweight were not significantly affected by DCA. However, behavioral tests, including morris water maze and step down, showed varying degrees of changes in DCA-treated pups. Additionally, we found significant difs, neuroinflammation response, and weakened synaptic plasticity in pups hippocampus induced by fetal exposure to DCA could damage the function of memory and cognition in the adulthood.Luffa spp. (sponge gourd or ridge gourd) is an economically important vegetable crop widely cultivated in China, India and Southeast Asia. Here, we employed PacBio long-read single-molecule real-time (SMRT) sequencing to perform de novo genome assemblies of two commonly cultivated Luffa species, L. acutangula and L. cylindrica. We obtained preliminary draft genomes of 734.6 Mb and 689.8 Mb with scaffold N50 of 786,130 and 578,616 bases for L. acutangula and L. cylindrica, respectively. We also applied long-range Chicago and HiC techniques to obtain the first chromosome-scale whole-genome assembly of L. acutangula. The final assembly contained 13 pseudomolecules, corresponding to the haploid chromosome number in Luffa spp. KPT-8602 (1n = 13, 2n = 26). The sizes of the assembled Luffa genomes are approximately twice as large as the genome assemblies of related Cucurbitaceae. A large proportion of L. acutangula (62.17%; 456.69 Mb) and L. cylindrica (56.78%; 391.65 Mb) genome assemblies contained repetitive elements. Phylogenetic analyses revealed that the substantial accumulation of transposable elements likely contributed to the expansion of the Luffa genomes. We also investigated alternative splicing events in Luffa using full-length transcript sequences obtained from PacBio Isoform Sequencing (Iso-seq). While the predominant form of alternative splicing in most plant species examined was intron retention, alternative 3' acceptor site selection appeared to be a major event observed in Luffa. High-quality genome assemblies for L. acutangula and L. cylindrica reported here provide valuable resources for Luffa breeding and future genetics and comparative genomics studies in Cucurbitaceae.
There is no good prognostic model that could predict the prognosis of bladder cancer (BCa) and the benefit of immunotherapy.
Through the least absolute shrinkage and selection operator (LASSO) algorithm, we constructed a 13-mRNA immune signature from the TCGA cohort (n=406). We validated its prognostic value and predictive value for the benefit of immunotherapy with four independent validation cohort (GSE13507 [n=256], GSE31684 [n=93], GSE32894 [n=308], and IMvigor210 cohort [n=298]).
Our results indicating that high-risk group with higher inhibitory immune cell infiltration (regulatory T cells [Tregs] and macrophage, etc), higher expression of immune checkpoints, and more T cell suppressive pathways (transforming growth factor β [TGF-β], epithelial-mesenchymal transition [EMT], etc) were activated. Besides, the immune signature showed a good predictive value for the benefit of immunotherapy in a cohort of urothelial carcinoma patients treated with PD-L1.
The immune signature constructed is convenient to classify the immunotherapeutic susceptibility of patients with BCa, so as to achieve precision immunotherapy for BCa.

To compare the diagnostic usefulness of the 2019 European League Against Rheumatism/American College of Rheumatology (2019-EULAR/ACR) classification criteria for systemic lupus erythematosus (SLE) to that of the 1997-ACR classification criteria for SLE (1997-ACR) when applied to youths (≤ 21 years) with SLE.
Data were extracted from electronic health records of patients followed at a large academic pediatric hospital. The treating rheumatologist's diagnosis of SLE served as the standard criterion for identifying SLE patients (cases). Controls were patients with juvenile dermatomyositis (JDM), juvenile scleroderma (jSc) or juvenile systemic sclerosis (jSSc). The 2019-EULAR/ACR criteria and the 1997-ACR criteria were tested against the standard criterion.
A total of 112 SLE patients aged 2-21 years and 105 controls aged 1-19 years (66% JDM, 34% jSc or jSSc) were available for analysis. The 2019-EULAR/ACR criteria had significantly higher sensitivity (85% vs 72%; p=0.023) and similar specificity (83% vs 87%; p=0.456) than the 1997-ACR criteria. The mean±SD 2019-EULAR/ACR classification summary scores were significantly higher among non-White than White cases (22.41±10.04 vs. 17.59±9.19; p<0.01). The sensitivity of the 2019-EULAR/ACR criteria in non-White/White cases was 92%/80% (p=0.08) vs 83%/64% (p<0.02) for the 1997-ACR criteria. The sensitivity of the 2019-EULAR/ACR criteria was not affected by age or gender.
The 2019-EULAR/ACR criteria efficiently classify youths with SLE, irrespective of age, gender and race. Compared to the 1997-ACR criteria, the new criteria are significantly more sensitive and similarly specific in youths with SLE.
