Hierarchically Structured Catalysts Toward Sustainable Hydrogen Economy: Electro- and Thermo-Chemical Pathways.

Hydrogen, as an important clean energy source, plays a more and more crucial role in decarbonizing the planet and meeting the global climate challenge due to its high energy density and zero-emission. The demand for sustainable hydrogen is increasing drastically worldwide as driven by the global shift towards low-carbon energy solutions. Thermochemical catalysis process dominates hydrogen production at scale given its relatively mature technology and commercialization status, as well as the established manufacturing infrastructure.

Cohort profile for the Tongji Cardiovascular Health Study: a prospective multiomics cohort study.

Purpose: The Tongji Cardiovascular Health Study aimed to further explore the onset and progression mechanisms of cardiovascular disease (CVD) through a combination of traditional cohort studies and multiomics analysis, including genomics, metabolomics and metagenomics.

Study Design And Participants: This study included participants aged 20-70 years old from the Geriatric Health Management Centre of Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology. After enrollment, each participant underwent a comprehensive series of traditional and novel cardiovascular risk factor assessments at baseline, including questionnaires, physical examinations, laboratory tests, cardiovascular health assessments and biological sample collection for subsequent multiomics analysis (whole genome sequencing, metabolomics study from blood samples and metagenomics study from stool samples).

A deep learning system for predicting time to progression of diabetic retinopathy.

Diabetic retinopathy (DR) is the leading cause of preventable blindness worldwide. The risk of DR progression is highly variable among different individuals, making it difficult to predict risk and personalize screening intervals. We developed and validated a deep learning system (DeepDR Plus) to predict time to DR progression within 5 years solely from fundus images.

Lower BCL11B expression is associated with adverse clinical outcome for patients with myelodysplastic syndrome.

Myelodysplastic syndrome (MDS) is an aggressive and genetically heterogeneous disease with poor prognosis. Cellular immune disorder is a common characteristic of this disease and is thought to be related to clinical outcome. Alterations in T cell clonal expansion and T cell dysfunction has been detected in MDS patients.

Pegylated liposomal mitoxantrone is more therapeutically active than mitoxantrone in L1210 ascitic tumor and exhibits dose-dependent activity saturation effect.

Our previous studies have proved that encapsulation of mitoxantrone into pegylated SUVs (plm60-s) could enhance its antineoplastic efficacy (Li et al., 2008b). However, why plm60-s is more therapeutically active than free mitoxantrone (MIT), and whether pharmacokinetics and activity of plm60-s exhibits dose-dependency are left unknown.

Accelerated blood clearance of pegylated liposomal topotecan: influence of polyethylene glycol grafting density and animal species.

Upon repeated administration, empty pegylated liposomes lose long-circulating characteristics, referred to as accelerated blood clearance (ABC) phenomenon. However, pegylated liposomal cytotoxic drug formulations could not elicit the phenomenon. In the study, it was found that repeated injection of pegylated liposomal topotecan could induce ABC phenomenon in Wistar rats, beagle dogs, and mice, which might be associated with the formation of empty liposomes in circulation because of the rapid drug release rate.

Sulfosalicylate mediates improved vinorelbine loading into LUVs and antineoplastic effects.

Liposomal vinorelbine formulation is desirable, as it might improve the therapeutic activity of vinorelbine. However, because of its lipophilic and membrane-permeable properties, vinorelbine is hard to be formulated into liposomes using conventional drug-loading technologies. To improve vinorelbine retention, ammonium salts of several anionic agents were employed to prepare liposomal vinorelbine formulations.
