Choice of open side affects clinical outcomes of unilateral open-door laminoplasty for inconsistent cervical ossification of the posterior longitudinal ligament.

Background: The best open side for unilateral open-door laminoplasty (UODL) to treat inconsistent cervical ossification of the posterior longitudinal ligament (OPLL) needs to be identified.

Methods: Thirty-one individuals with inconsistent OPLL who underwent UODL between January 2016 and December 2018 were retrospectively divided into two groups: when the side of the open door was consistent with the side of the larger ossification occupancy area, patients were placed in the Consistent group; when the side of the open door was contralateral to the side of the larger ossification occupancy area, patients were placed in the Contralateral group. The following parameters were evaluated: neck disability index (NDI) score, Japanese Orthopaedic Association (JOA) score, visual analog scale (VAS) score, postoperative laminoplasty opening width and angle, and spinal cord diameter ratio.

Azo-PMA nanopores of sub-20 nm length for unimolecular resolution of nucleic acids and proteins.

Owing to the facile fabrication and surface modification, the cost-effective polymer nanopores are widely employed in unimolecular determination of biomacromolecules and selective sensing of small molecules, nanoparticles and biomarkers. However, the documented polymer nanochannels are generally microscale in length with low spatial resolution. We herein synthesized azobenzene side-chain polymer (Azo-PMA) and spin-coated on silicon nitride membrane to obtain a polymer film of nanoscale thickness for further nanopore generation via controlled dielectric breakdown (CDB) approach.

C Stable Isotope Tracing Reveals Distinct Fatty Acid Oxidation Pathways in Proliferative vs. Oxidative Cells.

The TCA cycle serves as a central hub to balance catabolic and anabolic needs of the cell, where carbon moieties can either contribute to oxidative metabolism or support biosynthetic reactions. This differential TCA cycle engagement for glucose-derived carbon has been extensively studied in cultured cells, but the fate of fatty acid (FA)-derived carbons is poorly understood. To fill the knowledge gap, we have developed a strategy to culture cells with long-chain FAs without altering cell viability.

Introduction: In Australia, older Aboriginal and Torres Strait Islander people have the highest prevalence of hearing loss, for which dedicated audiological services are available. However, there is limited research on the experiences older Aboriginal and Torres Strait Islander people have with hearing loss and audiological services. Therefore, this study aimed to consolidate existing literature with a scoping review, specifically on the above to identify gaps and guide future research.

DMS behaviors in pen culture of Sinonovacula constricta in Longhai, China.

Dimethyl sulfide (DMS) released by the ocean has received widespread attention due to its role in aerosol formation and impact on global climate change. Research on DMS mainly focuses on coastal and open ocean environments, with limited studies addressing the influence of aquaculture activities on the production and release of marine DMS. Thus, we investigated whether fertilization for algae cultivation and the feeding process in pen culture of Sinonovacula constricta significantly contribute to DMS release.

Directly Characterizing the Capture Radius of Tethered Double-Stranded DNA by Single-Molecule Nanopipette Manipulation.

The tethered molecule exhibits characteristics of both free and fixed states, with the electrodynamics involved in its diffusion, electrophoresis, and stretching processes still not fully understood. We developed a Single-Molecule Manipulation, Identification, and Length Examination (SMILE) system by integrating piezoelectric devices with nanopipettes. This system enabled successful capture and stretching of tethered double-stranded DNA within the nanopore.

Radiopharmaceuticals Targeting Gastrin-Releasing Peptide Receptor for Diagnosis and Therapy of Prostate Cancer.

The high incidence and heavy disease burden of prostate cancer (PC) require accurate and comprehensive assessment for appropriate disease management. Prostate-specific membrane antigen (PSMA) positron emission tomography (PET) cannot detect PSMA-negative lesions, despite its key role in PC disease management. The overexpression of gastrin-releasing peptide receptor (GRPR) in PC lesions reportedly performs as a complementary target for the diagnosis and therapy of PC.

We described the findings of 68 Ga-FAPI-04 PET/CT of psoriatic arthritis in a 56-year-old man. Intense FAPI uptake was observed alongside the spine and in the joints of bilateral feet and the right hip. 68 Ga-FAPI PET/CT is potentially valuable for the evaluation of join involvement and disease activity in patients with psoriasis.

Critical new insights into the interactions of hexafluoropropylene oxide-dimer acid (GenX or HFPO-DA) with albumin at molecular and cellular levels.

A key characteristic to be elucidated, to address the harmful health risks of environmental perfluorinated alkyl substances (PFAS), is their binding modes to serum albumin, the most abundant protein in blood. Hexafluoropropylene oxide-dimer acid (GenX or HFPO-DA) is a new industrial replacement for the widespread linear long-chain PFAS. However, the detailed interaction of new-generation short-chain PFAS with albumin is still lacking.

NAD metabolism and heart failure: Mechanisms and therapeutic potentials.

Nicotinamide adenine dinucleotide provides the critical redox pair, NAD and NADH, for cellular energy metabolism. In addition, NAD is the precursor for de novo NADP synthesis as well as the co-substrates for CD38, poly(ADP-ribose) polymerase and sirtuins, thus, playing a central role in the regulation of oxidative stress and cell signaling. Declines of the NAD level and altered NAD/NADH redox states have been observed in cardiometabolic diseases of various etiologies.

Impact of sea ice on the physicochemical characteristics of marine aerosols in the Arctic Ocean.

Marine aerosols (MA) can be influenced by sea ice concentration, potentially playing a pivotal role in the formation of cloud condensation nuclei and exerting an impact on regional climate. In this study, a high-resolution aerosol observation system was employed to measure the concentration and size of aerosols in the floating ice region and seawater region of the Arctic Ocean during the 8th and 9th Chinese Arctic Expedition Research Cruise. The identification of aerosol sources was conducted using a modified positive definite matrix factorization method and a backward air mass trajectory model.
