High-Capacity Volumetric Methane Storage in Hyper-Cross-Linked Porous Polymers via Flexibility Engineering of Building Units.

Adsorbed natural gas (ANG) storage is emerging as a promising alternative to traditional compressed and liquefied storage methods. However, its onboard application is restricted by low volumetric methane storage capacity. Flexible porous adsorbents offer a potential solution, as their dense structures and unique gate-opening effects are well-suited to enhance volumetric capacity under high pressures.

Mechanically reconfigurable cavity filters using liquid metals in the W-band.

The high adaptability and flexibility of reconfigurable cavity filters (RCFs) provide a compelling solution for signal modulation in communication systems. However, current reports on these filters are predominantly concentrated within the frequency range of a few GHz. As communication frequencies continue to escalate, there is a pressing need for filters that can operate at higher frequencies.

Optimization analysis for the maximum pairing length of mode-pairing quantum key distribution.

Mode-pairing quantum key distribution (MP-QKD) circumvents the need for phase locking through post-selection pairing, still allowing it to surpass the repeaterless rate-transmittance limit. This protocol, therefore, presents a promising approach for practical QKD implementation. Without phase locking and tracking, the performance of the laser, channel, and detector critically affects the determination of the maximum pairing length in pairing strategies.

Imaging of endogenous RNA in live cells using sequence-activated fluorescent RNA probes.

RNA performs a remarkable range of functions, such as RNA processing, chromosome maintenance and dosage compensation. Technologies that robustly and specifically image RNA in its native state are highly desirable, as these technologies can help researchers clarify the localization and functionality of diverse RNAs. Here, we describe the development of a sequence-activated fluorescent RNA (SaFR) technique.

Apoptosis Signal-Regulated Kinase-1 Promotes Nucleus Pulposus Cell Senescence and Apoptosis to Regulate Intervertebral Disc Degeneration.

This study investigated the role of apoptosis signal-regulated kinase-1 (ASK1) in intervertebral disc degeneration (IDD). The nucleus pulposus (NP) tissues of non-IDD and IDD patients were subjected to hematoxylin and eosin, Safranin O-fast green, and immunohistochemical staining. Quantitative real-time PCR was used to assess the ASK1 mRNA level within NP tissue samples and cells.

Enhancing the performance of mode-pairing quantum key distribution by wavelength division multiplexing.

Mode-pairing quantum key distribution (MP-QKD) holds great promise for the practical implementation of QKD in the near future. It combines the security advantages of measurement device independence while still being capable of breaking the Pirandola-Laurenza-Ottaviani-Banchi bound without the need for highly demanding phase-locking and phase-tracking technologies for deployment. In this work, we explore optimization strategies for MP-QKD in a wavelength-division multiplexing scenario.

Apolipoprotein O modulates cholesterol metabolism via NRF2/CYB5R3 independent of LDL receptor.

Dibromomethane Knitted Highly Porous Hyper-Cross-Linked Polymers for Efficient High-Pressure Methane Storage.

Hyper-cross-linked polymers (HCPs) with ultra-high porosity, superior physicochemical stability, and excellent cost-effectiveness are attractive candidates for methane storage. However, the construction of HCPs with BET surface areas exceeding 3000 m g remains extremely challenging. In this work, a newly developed DBM-knitting method with a slow-knitting rate is employed to increase the cross-linking degree, in which dichloromethane (DCM) is replaced by dibromomethane (DBM) as both solvent and electrophilic cross-linker, resulting in highly porous and physicochemically stable HCPs.

Advancements in dual-target inhibitors of PI3K for tumor therapy: Clinical progress, development strategies, prospects.

Phosphoinositide 3-kinases (PI3Ks) modify lipids by the phosphorylation of inositol phospholipids at the 3'-OH position, thereby participating in signal transduction and exerting effects on various physiological processes such as cell growth, metabolism, and organism development. PI3K activation also drives cancer cell growth, survival, and metabolism, with genetic dysregulation of this pathway observed in diverse human cancers. Therefore, this target is considered a promising potential therapeutic target for various types of cancer.

Small-molecule LRRK2 inhibitors for PD therapy: Current achievements and future perspectives.

Leucine-rich repeat kinase 2 (LRRK2) is a multifunctional protein that orchestrates a diverse array of cellular processes, including vesicle transport, autophagy, lysosome degradation, neurotransmission, and mitochondrial activity. Hyperactivation of LRRK2 triggers vesicle transport dysfunction, neuroinflammation, accumulation of α-synuclein, mitochondrial dysfunction, and the loss of cilia, ultimately leading to Parkinson's disease (PD). Therefore, targeting LRRK2 protein is a promising therapeutic strategy for PD.

Loss of APOO (MIC26) aggravates obesity-related whitening of brown adipose tissue via PPARα-mediated functional interplay between mitochondria and peroxisomes.

Background: Mitochondrial dysfunction and aberrant structure in adipose tissue occur in obesity and obesity-linked brown adipose tissue (BAT) whitening; however, whether this aberrant architecture contributes to or is the result of obesity is unknown. Apolipoprotein O (APOO) is a constitutive protein of the mitochondrial cristae organizing system complex. This study aimed to characterize the physiological consequences of APOO deficiency in vivo.

Sirolimus for the treatment of patients with refractory connective tissue disease-related thrombocytopenia: a pilot study.

Objective: CTD-related immune thrombocytopenia (CTD-ITP) represents an unmet medical need because the drugs that are available are only partly effective and have considerable side-effects. The aim of this study was to assess the efficacy and safety of sirolimus in refractory CTD-ITP patients.

Methods: We did a single-arm, open-label, pilot study of sirolimus in patients with CTD-ITP unresponsive to, or intolerant of, conventional medications.

Intrathecal injection of methotrexate combined with dexamethasone for Cogan's syndrome with neurological involvement: A case report and literature review.

Cogan's syndrome (CS) is a rare autoimmune disease in which approximately 10%-13% of people with the condition develop neurological symptoms. While glucocorticoids are the standard of care for patients with CS, disease-modifying anti-rheumatic drugs (DMARDs) and biologics agents are more widely used to treat the systemic and vestibular auditory manifestations of CS. Herein, we report a rare case of CS with central nervous system damage who failed to respond to systemic use of glucocorticoids and DMARDs.
