Molecules with high point-group symmetry are interesting prototype species in the textbook. As transition metal-centered boron clusters tend to have highly symmetric structures to fulfill multicenter bonding and high stability, new boron clusters with rare point-group symmetry may be viable. Through in-depth scrutiny over the structures of experimentally already observed transition metal-centered boron-wheel complexes, geometric and electronic design principles are summarized, based on which we studied M©B ( = Y, La; Zr, Hf; = 1, 2) clusters and found that a Y©B boron-wheel complex has an unprecedented point-group symmetry.

Pulmonary fibrosis is a chronic and progressive disease, current systemic administration is not fully effective with many side effects, such as gastrointestinal and liver injury. The pulmonary delivery system for pulmonary fibrosis may contribute to maximize therapeutic benefit. Natural compounds might have prominence as potential drug candidates, but the low bioavailabilities affect their clinical use.

Ethnopharmacological Relevance: Interstitial lung disease (ILD) is a chronic lung dysfunction disease with a poor prognosis and poor recovery. The clinically used therapeutic drugs, such as glucocorticoids and immunosuppressants, have no significant therapeutic effect and are accompanied with severe side effects. In recent years, considerable progress has been made in exploring and applying natural herb components for treating ILD.

Background: Hemodynamically significant patent ductus arteriosus (hsPDA) is associated with increased comorbidities in neonates. Early evaluation of hsPDA risk is critical to implement individualized intervention. The aim of the study was to provide a powerful reference for the early identification of high-risk hsPDA population and early treatment decisions.

Objectives: To explore the application of whole-genome sequencing (WGS) in the rapid clinical diagnosis of critically ill neonates.

Methods: The critically ill neonates who admitted to the neonatal intensive care unit of Children's Hospital of Fudan University and underwent WGS from August to September, 2019 were enrolled in this prospective study. The genetic testing results and clinical outcome were analyzed with reference to the sequencing data and clinical features of the neonates.

Background: During next generation sequencing (NGS) data interpretation in critically ill newborns, there is a potential for recognizing and reporting secondary findings (SFs). Early awareness of SFs may provide clues for disease prevention. In this study, we assessed the frequency of SFs in the China Neonatal Genomes Project (CNGP) participants.

Background: Coronavirus disease 2019 (COVID-19) is currently rampant worldwide, resulting in unpredictable harm to humans. High blood levels of cytokines and chemokines have been marked in patients with COVID-19 infection, leading to cytokine storm syndrome. Cytokine storms are violent inflammatory immune responses that reveal the devastating effect of immune dysregulation and the critical role of an effective host immune response.

Article Synopsis
  • The study investigates how factors during the neonatal period can predict the prognosis of infants with KCNQ2-related disorders, which range in severity from benign seizures to severe epilepsy.
  • A total of 52 infants were analyzed, and results showed that early interictal video-electro-encephalography (VEEG) and the location of genetic variants are significant indicators of prognosis, with worse VEEG correlating to poorer outcomes.
  • The findings suggest that infants with KCNQ2 variants in critical areas, alongside negative early VEEG results, are likely to experience adverse developmental outcomes.

Article Synopsis
  • Infantile hydrocephalus (IHC) is linked to various central nervous system diseases, and its genetic causes are not yet fully understood; this study focused on identifying genetic factors in IHC patients.
  • The research analyzed data from 110 IHC patients who underwent exome sequencing, finding that about 15% had pathogenic variants in 13 different genes primarily associated with metabolic and brain disorders.
  • The findings suggest that genetic testing is crucial for IHC patients with unclear causes, and specific genes affecting signaling pathways should be prioritized in future IHC research.

The discovery of borospherenes unveiled the capacity of boron to form fullerene-like cage structures. While fullerenes are known to entrap metal atoms to form endohedral metallofullerenes, few metal atoms have been observed to be part of the fullerene cages. Here we report the observation of a class of remarkable metallo-borospherenes, where metal atoms are integral parts of the cage surface.

This article reports the clinical and genetic features of two cases of cerebral creatine deficiency syndrome I (CCDSI) caused by SLC6A8 gene mutations. Both children were boys. Boy 1 (aged 2 years and 10 months) and Boy 2 (aged 8 years and 11 months) had the clinical manifestations of delayed mental and motor development, and convulsion.

Background: Maple syrup urine disease (MSUD) is an autosomal recessive inherited disorder that affects the degradation of branched-chain amino acids and is associated with acute and chronic brain dysfunction. This study presents 11 new patients with MSUD and describes the clinical characteristics and gene mutations reported in Chinese individuals.

Methods: During 2011-2018, 11 pedaitric patients with MSUD from 11 Chinese families were analyzed based on clinical characteristics and mass spectrometry, with confirmation via gene sequencing.

Transition-metal-centered monocyclic boron wheel clusters (M©B ) represent a family of interesting borometallic compounds with double aromaticity. A variety of early and late transition metal atoms have been found to form such structures with high symmetries and various B ring sizes. Here we report a combined photoelectron spectroscopy and quantum-chemistry theoretical study of two M©B clusters from the middle of the transition metal series: Re©B and Re©B.

Gene and drug therapies are being developed to alleviate vision loss in patients with Stargardt's disease and age-related macular degeneration (AMD). To evaluate the therapeutic effects of these treatments, organic solvents are routinely used to extract and quantify bisretinoid lipofuscin constituents, such as N-retinylidene-N-retinyl-ethanolamine (A2E) and all-trans-retinal dimer (ATR-dimer). By high-performance liquid chromatography (HPLC), we found that A2E and ATR-dimer were both altered by tetrahydrofuran (THF) and chloroform, but were stable in dimethyl sulfoxide (DMSO) or methanol (MeOH).
