Neurological disorders are a diverse group of conditions that affect the nervous system and include neurodegenerative diseases(Alzheimer’s disease,multiple sclerosis,Parkinson’s disease,Huntington’s disease),cerebrovascular conditions(stroke),and neurodevelopmental disorders(autism spectrum disorder).Although they affect millions of individuals around the world,only a limited number of effective treatment options are available *** most neurological disorders express mitochondria-related metabolic perturbations,metformin,a biguanide type II antidiabetic drug,has attracted a lot of attention to be repurposed to treat neurological disorders by correcting their perturbed energy ***,controversial research emerges regarding the beneficial/detrimental effects of metformin on these neurological *** that most neurological disorders have complex etiology in their pathophysiology and are influenced by various risk factors such as aging,lifestyle,genetics,and environment,it is important to identify perturbed molecular functions that can be targeted by metformin in these neurological *** molecules can then be used as biomarkers to stratify subpopulations of patients who show distinct molecular/pathological properties and can respond to metformin treatment,ultimately developing targeted *** this review,we will discuss mitochondria-related metabolic perturbations and impaired molecular pathways in these neurological disorders and how these can be used as biomarkers to guide metformin-responsive treatment for the targeted therapy to treat neurological disorders.

In this study, we present a representative case of multiple glomuvenous malformation in a 12-year-old female patient. Approximately five years ago, the patient developed multiple blue-purple papules and plaques on her hypogastrium and right thigh, which progressively enlarged and presented tenderness. Histopathological examination confirmed the diagnosis of glomuvenous malformation. Following two injections of lauromacrogol, a significant improvement was observed in the lesions, including a resolution of tenderness. These findings suggest that sclerotherapy not only exhibits evident therapeutic efficacy but also effectively alleviates pain while addressing both aesthetic and therapeutic concerns.

Phenolation is one of the effective strategies to synthesize lignin-based polyphenols,improve lignin’s properties,and extend its value-added applications in biological,medicinal and cosmetic ***,by taking the structural feature advantage of lignin,an effective and green strategy was developed to molecularly engineer lignin into a robust lignin-3-(2-hydroxyphenyl)propionate ester(LPPE)derivative via a transesterification reaction between 3,4-dihydrocoumarin(DHC)and the aliphatic hydroxyls in lignin under *** strategy is optimized and the novel derivative was systematically characterized by ^(1)H,^(13)C and ^(31)P nuclear magnetic resonance(NMR)and Fourier transform infrared(FT-IR)*** findings indicated that the successful introduction of 3-(2-hydroxyphenyl)propionate groups using a OH groups/DHC/organic base mo-lar ratio of 1꞉1꞉0.3 at 120℃ for 6 h increased the content of phenolic hydroxyl groups from 1.7931 to 3.0179 mmol/g,and the LPPE exhibited excellent ultraviolet-absorbing and antioxidant per-formance with up to 90%free radical scavenging activity within 20 min using 5 mg/mL of *** addition,good biocompatibility and a high sun protection factor(sPF)value of 40.9 were achieved at 5%(w)dosage of LPPE in the cream,indicating its significant application potential in sunscreen.

Dear editor,site specific recombinases have been widely used for genome engineering in cardiovascular research(Fu et al.,2024;Huang et al.,2023;Xue et al.,2022).In particular,Cre is the most broadly used recombinase for cell type-specific lineage tracing and gene manipulation in *** smooth muscle cell(sMC)-specific targeting,several sMC promoters including Myh11(smooth muscle myosin heavy chain),Acta2(smooth muscle a-2 actin),and sM22a(Tagln)have been used to drive Cre or CreER.

The sARs-CoV-2 Omicron variants are notorious for their transmissibility,but little is known about their subgenomic RNA(sgRNA)*** study applied RNA-seq to delineate the quantitative and qualitative profiles of canonical sgRNA of 118 respiratory samples collected from patients infected with Omicron BA.2 and compared with 338 patients infected with non-variant of concern(non-VOC)-D614G.A unique characteristic profile depicted by the relative abundance of 9 canonical sgRNAs was reproduced by both BA.2 and non-VOCD614G regardless of host gender,age and presence of ***,such profile was lost in samples with low viral load,suggesting a potential application of sgRNA pattern to indicate viral activity of individual patient at a specific time point.A characteristic qualitative profile of canonical sgRNAs was also reproduced by both BA.2 and *** presence of a full set of canonical sgRNAs carried a coherent correlation with crude viral load(AUC¼0.91,95%CI 0.88–0.94),and sgRNA ORF7b was identified to be the best surrogate marker allowing feasible routine application in characterizing the infection status of individual *** potentials in using sgRNA as a target for vaccine and antiviral development are worth pursuing.

全面抗战爆发后,道教会负责动员道教徒参与抗战活动和筹募经费等工作。在前期的组织管理中,道教会面临道众抵抗与经费不足的困境。因此,道教会根据地方实际情况,改革经费征收模式,通过征收经忏捐与规范经忏的方式,扩大经费来源。在此过程中,地方道教会利用这一特殊时期,初步掌握对道教徒及其经忏业务的管理权,改变以往地方道教界“松散”的形态,对所辖境内的道教徒实施从人到财产全方位的统合与管控。道教会所采取的经费改革,逐步冲击传统道教界的运行秩序,走向现代组织化的管理模式。
