Background: Surgical management methods for Hepple IV-V osteochondral lesions of the talus (OLT) are diverse. This study aimed to compare the clinical efficacy of arthroscopic autologous cancellous bone grafting and medial malleolar osteotomy combined with autologous periosteal iliac bone grafting in the treatment of medial Hepple IV-V OLT.
Methods: A retrospective analysis of clinical data from patients who underwent surgical treatment for Hepple IV-V OLT (2020-2023) was conducted.
Chemotherapy is important in the systemic therapy for breast cancer. However, after chemotherapy, the left living tumour cells are more progressive. There is an urgent need to study the underlying mechanism which is still unclear to further improve the therapeutic efficacy of chemotherapy in breast cancer.

To address this, we introduced a cell-type-specific, multi-target drug discovery strategy grounded in human data and real-world evidence. This approach integrates single-cell transcriptomics, drug perturbation databases, and clinical records.

The high entropy oxide NaNiFeMnTiSnCoLiO (HEO) is synthesized by leveraging the entropy stabilization effect, which offers a partial solution to this issue, but electrochemical performance and air stability imperative to be improved. On the high entropy oxide HEO, due to the strong bond energy of Ce-O, the introduction of Ce improves the specific discharge capacity and reduces the battery gas production problem.

Soil microbial carbon use efficiency (CUE) refers to the efficiency of microorganisms in converting absorbed carbon into their own biomass carbon. Soil microbial CUE is a key parameter to understanding the soil carbon cycle. Biotic and abiotic factors are widely considered to be important factors influencing CUE.

Historically, SOF were assumed to be resilient to the psychological sequelae of war, including posttraumatic stress disorder (PTSD). However, the objective burden of PTSD in SOF, particularly after traumatic brain injury (TBI), remains unknown.

Cell surface glycosylation plays an important role in immune cells; however, the N-glycosylation and glycosphingolipid (GSL) signatures of activated microglia are poorly understood. Here, we study comprehensive combined transcriptomic and glycomic profiles using human induced pluripotent stem cells-derived microglia (hiMG).

Five healthy men consumed a standardized breakfast, followed by control (wheat flour) or low, medium, or high doses of supplements containing spermidine, nicotinamide, PEA, and OEA 2 hours later. Blood was drawn at 0, 1, 2, and 4 hours after the supplement (2, 3, 4, and 6 hours postprandial).

The spherical NaNiFeMnTiSnCoLiO (SP-HEO) has been developed to address the challenges faced by O3-type layered oxide in sodium-ion batteries. The SP-HEO material is synthesized by piling and high entropy.

It has been shown that nanoporous structures can limit the development of electron avalanche, leading to a significant increase in the breakdown electric strength of dielectrics. Hence, we fabricated a polysiloxane nanoporous biopolymer insulating material (PNBIM) with the nanoporous structure that presents exceptionally high electrically insulating properties.

Design: Literature review, two-round e-Delphi study, and quantitative studies.
Methods: With the recommended opinions of clinical practice guidelines for cataract surgery as the guiding framework, an item pool was formed on the basis of literature review and guideline content analysis, and the dimensions and items of evaluation program were determined by two rounds of correspondence consultation using Delphi expert method.
Objective: To study the effects of astragalus polysaccharide (APS) on aplastic anaemia (AA) in mice through modulation of the upstream and downstream effectors of the Hippo pathway. Further, we investigated the underlying mechanisms of APS in the treatment of AA to provide possible therapeutic strategies and drugs for clinical use.
Methods: BALB/c mice were subjected to 4 Gy X-ray irradiation and subsequently injected with lymphocytes from DBA/2 donor mice by using the tail vein to establish an AA mouse model.
Surfactants are hailed as "industrial monosodium glutamate", and are widely used as emulsifiers, demulsifiers, water treatment agents, etc., in the petroleum industry. However, due to the unidirectivity of conventional surfactants, the difficulty in demulsifying petroleum emulsions generated after emulsification with such surfactants increases sharply.

The grafting ratio of VTMS on the calcined kaolinite surface was adjusted by varying its quantity. FT-IR analysis revealed the initial grafting of VTMS onto the kaolinite surface, resulting in the formation of a C=C reactive site on the surface.

The serine-threonine liver kinase B1 (LKB1) is a master upstream kinase of 5'-AMP-activated protein kinase (AMPK) that senses the energy status and therefore regulates the intracellular metabolic homeostasis. Previous studies showed that AMPK restricts Kaposi's sarcoma-associated herpesvirus (KSHV) lytic replication in endothelial cells during primary infection and promotes primary effusion lymphoma (PEL) cell survival.

Direct regeneration has gained much attention in LiFePO battery recycling due to its simplicity, ecofriendliness, and cost savings. However, the excess carbon residues from binder decomposition, conductive carbon, and coated carbon in spent LiFePO impair electrochemical performance of direct regenerated LiFePO. Herein, we report a preoxidation and prilling collaborative doping strategy to restore spent LiFePO by direct regeneration.
