Spinal Epidural Hematoma Following Combined Spinal Epidural Anesthesia: A Case Report.

A spinal epidural hematoma (SEH) is a rare complication of combined spinal epidural anesthesia. The case of a 55-year-old man who underwent orthopedic surgery under combined spinal epidural anesthesia is presented. Flurbiprofen and horse chestnut seed extract that potentially affect coagulation function during the perioperative period were used.

Engineering ZIF-8@Ag core-satellite superstructures through solvent-induced tunable self-assembly for surface-enhanced Raman spectroscopy.

Metal-organic framework (MOF) based substrates have great potential for quantitative analysis of hazardous substances using surface-enhanced Raman spectroscopy (SERS) due to their significant signal enhancement, but face challenges like complex preparation, and lack of tunability. Here, we have successfully prepared a well-defined core-satellite superstructure (ZIF-8@Ag) through solvent-induced assembly of silver nanoparticles (Ag NPs) on truncated rhombic dodecahedral ZIF-8. By wisely selecting toluene as the solvent, the assembly process can be easily initiated through ultrasonic treatment and it allows for precise morphological adjustments to build a range of superstructures with different assembly densities of Ag NPs feed ratio tuning.

Local Polarization Piezoelectric Electric Field Promoted Water Dissociation for Hydroxyl Radical Generation under Ambient Humidity Condition.

Combining piezocatalysts with mechanical ball milling for dissociating water to generate hydroxyl radicals (·OH) offers unprecedented opportunities for energy conversion and environmental remediation. However, the in-depth insights into the relationship between water and local polarization piezoelectric electric field (LPPEF) are currently lacking, in particularly, the ·OH formation mechanism in ball milling driven piezocatalyst system is not systematically elucidated. To this end, the present work constructs a ball milling driven piezoelectric solid/liquid interface between piezoelectric PbBOCl (PBOC) and different contents of water to investigate LPPEF initiated catalytic reaction.

DLBWE-Cys: a deep-learning-based tool for identifying cysteine S-carboxyethylation sites using binary-weight encoding.

Cysteine S-carboxyethylation, a novel post-translational modification (PTM), plays a critical role in the pathogenesis of autoimmune diseases, particularly ankylosing spondylitis. Accurate identification of S-carboxyethylation modification sites is essential for elucidating their functional mechanisms. Unfortunately, there are currently no computational tools that can accurately predict these sites, posing a significant challenge to this area of research.

Evaluation and comparison of reading man flap based on different designs of angles and central axial lengths using finite element method.

Different angles and central axis length combinations of the reading man flap were studied to determine the optimal angles and central axis length combinations for reducing the stress on the flap tip. First, different models and corresponding finite element models of flaps with different angles and central axial lengths were established by ANSYS software. Then, skin flap transfer was achieved through forced displacement, and the stress distributions of the flap with different angles and central axial lengths under different materials were obtained.
