Summary: Spinal cord injury is a severe central nervous system injury that leads to sensory and motor dysfunction. The PI3K/Akt signaling pathway plays a key role in the pathological processes and neuronal recovery of spinal cord injury, and its activation can promote neurological function recovery by reducing cell apoptosis.

Summary: Promoting blood-spinal cord barrier (BSCB) repair at the early stage plays a crucial role in treatment of spinal cord injury (SCI). A sustained-release system of basic fibroblast growth factor (bFGF) (called ALG-bFGF) has been developed using sodium alginate hydrogel, which shows improved therapeutic effect in promoting SCI repair and motor function recovery. The mechanism involves the inhibition of autophagy activation and maintenance of BSCB integrity through the PI3K/Akt/FOXO1/KLF4 pathway.

Summary: The present study aimed to investigate the pro-angiogenic potential of OECs activated by CCM and LPS and the underlying mechanisms. The activated OECs were found to effectively promote proliferation, migration, and vessel-like structure formation of vascular endothelial cells. Several pro-angiogenic growth factors were significantly elevated in the conditioned medium (CM), and the PI3K/Akt signaling pathway was involved in these pro-angiogenic events. Transplantation of activated OECs improved angiogenesis and the microenvironment in the injured spinal cord.

Summary: This study found that MND1 is highly expressed in gastric cancer and is associated with resistance to the chemotherapy drug oxaliplatin. Overexpression of MND1 is linked to worse prognosis and advanced pathological characteristics in gastric cancer patients. FOXA1 regulates gastric cancer progression by inhibiting the transcription of MND1. The interaction between MND1 and TKT activates the PI3K/AKT signaling pathway, promoting gastric cancer progression.

Summary: This study found that compared with nondiabetic patients, there was no significant upregulation of FOXO3 alpha in diabetic patients after cardiopulmonary bypass surgery, which may explain the lack of upregulation of the autophagy process. FOXO3 alpha could potentially serve as a therapeutic target to improve cellular homeostasis.

Summary: In this study, a 1D pi-d conjugated metal-organic framework (MOF), Ni-MOF-1D, is presented as an efficient sulfur host to overcome the shuttling behavior and sluggish conversion kinetics of intermediate lithium polysulfides (LiPS) in lithium-sulfur batteries (LSBs). Ni-MOF-1D exhibits a remarkable binding strength to trap soluble LiPS species and acts as an effective catalyst for S reduction and Li2S oxidation. The delocalization of electrons in the pi-d system of Ni-MOF-1D provides superior electrical conductivity, leading to excellent performance in LSBs.

Summary: This study aimed to compare the biomechanical properties of different lengths of fibula with or without calcar screw in osteoporotic proximal humeral fracture. The results showed that the groups with a 12-cm fibular strut had significant improvement in terms of initial stiffness, number of cycles loaded to failure, and relative displacement values compared to the groups with a 6-cm fibular strut, regardless of calcar screw implementation. Furthermore, the groups with calcar screws also demonstrated promising biomechanical stability irrespective of fibular length. Therefore, the use of lateral locking plate with longer endosteal fibular augmentation and calcar screw can significantly improve biomechanical stability for elderly proximal humeral fractures with posteromedial comminution.

Summary: This study aims to screen patients with osteoporosis and predict their clinical outcomes using effective parameters obtained from hip CT scans. The cortical bone thickness (CTh) of ROI 21 and Hounsfield unit (HU) values of ROI 14 were moderately correlated with hip BMD. Thresholds for osteoporosis based on CTh and HU values could accurately screen osteoporosis, and the clinical outcomes of nonosteoporotic group were better than those of osteoporotic group.

Summary: In this study, Pd3Pb@Pt core-shell nanocubes with controlled shell thickness were synthesized using Pt-seeded epitaxial growth on intermetallic Pd3Pb cores. The lattice mismatch between the Pd3Pb core and the Pt shell resulted in the expansion of the Pt lattice, leading to excellent electrocatalytic performance for both ethanol oxidation reaction (EOR) and hydrogen evolution reaction (HER).

Summary: This study aimed to explore a novel oblique triangle configuration (OTC) of three screws for fixing femoral neck fractures based on the morphology of the femoral neck isthmus (FNI). The OTC method provided an ideal spatial configuration for the FNA fixation with the largest area using three parallel screws. The positioning of the posterior screw also reduced the risk of vascular injury and screw penetrating.
