The distinctive cavity structure of cyclodextrin, which results in binding properties, is credited with its application prospects in chemical, pharmacy, and material fields. The binding capacity can be regulated by substituting the hydroxyl groups on the cyclodextrins. It is possible to acquire anticipated binding properties by designing the modified groups on cyclodextrins.

We have developed a novel strategy for decarboxylative radical addition reactions that employs ground-state reduced nicotinamide adenine dinucleotide (NADH) analogues under ambient and open-air conditions, facilitating the efficient formation of Csp-Csp bonds in a variety of substrates. This protocol is distinguished by its operational simplicity, mild reaction conditions, high efficiency, and the use of cost-effective starting materials. Furthermore, experimental studies have provided valuable insights into the reaction mechanism, elucidating the light-independent pathways that promote these transformations.

Article Synopsis
  • The study focuses on Kcoronene, a potassium-intercalated polycyclic aromatic hydrocarbon, detailing its synthesis, structure, and magnetic properties while outlining a computational method to identify suitable PAHs for metal intercalation.
  • Coronene was selected based on a screening of its electronic structure and available void space, demonstrating stability when intercalated with three potassium ions per coronene molecule.
  • Despite structural changes and disorder caused by potassium intercalation, Kcoronene did not exhibit superconductivity, which contrasts with earlier findings and may be linked to the extensive structural disruption observed.

Purpose: This study aims to investigate how aspirin influences lumbar degeneration by analyzing the effect of aspirin on patients with low back pain (LBP) and concurrent atherosclerosis.

Methods: Using 1:1 nearest neighbor matching based on propensity score matching (PSM), 73 patients who regularly took aspirin were assigned to the aspirin group, while another 73 patients who did not take aspirin formed the control group. Radiographs were used to measure lumbar lordosis (LL) and intervertebral height index (IHI).

Introduction: The present study examined the moderating effects of undergraduate collectivism in the relations between parents' acceptance/rejection and undergraduate adjustment to college in Chinese societies.

Methods: A survey was conducted covering 5,444 Chinese undergraduates and involved the use of the Parental Acceptance and Rejection Questionnaires (PARQ-short form), the College Student Adaptability Inventory (CSAI), and the Individualism-Collectivism Scale (ICS).

Results: Findings revealed that undergraduate's collectivism moderated the relations between acceptance/rejection and undergraduate adjustment to college for fathers, but not for mothers.

Aims: Biomarkers are pivotal in the management of heart failure (HF); however, their lack of cardiac specificity could limit clinical utility. This study aimed to investigate the transcoronary changes and intracardiac production of these biomarkers.

Methods: Transcoronary gradients for B-type natriuretic peptide (BNP) and five novel biomarkers-galectin-3 (Gal-3), soluble suppression of tumourigenicity 2 (sST2), tissue inhibitor of metalloproteinase 1 (TIMP-1), growth differentiation factor 15 (GDF-15) and myeloperoxidase (MPO)-were determined using femoral artery (FA) and coronary sinus (CS) samples from 30 HF patients and 10 non-HF controls.

Humanoid robots are becoming a global research focus. Due to the limitations of bipedal walking technology, mobile humanoid robots equipped with a wheeled chassis and dual arms have emerged as the most suitable configuration for performing complex tasks in factory or home environments. To address the high redundancy issue arising from the wheeled chassis and dual-arm design of mobile humanoid robots, this study proposes a whole-body coordinated motion control algorithm based on arm potential energy optimization.

Biomimetic vision is a promising method for efficient navigation and perception, showing great potential in modern navigation systems. Optical flow information, which comes from changes in an image on an organism's retina as it moves relative to objects, is crucial in this process. Similarly, the star sensor is a critical component to obtain the optical flow for attitude measurement using sequences of star images.

Rheumatoid arthritis (RA) and cardiovascular disease (CVD) are both the chronic inflammatory disease. To investigate the influence of secondary atherosclerosis on arthritis mice, we treated the ApoE mice with K/BxN serum and high fat diet (HFD), and subsequently assessed the phenotypes as well as immune profiles of K/BxN serum and HFD induced ApoE mice. We found that HFD treatment aggravated the hyperlipidemia, atherosclerotic lesions, ankle swelling and arthropathy of mice.

Background: Sepsis is a systemic inflammatory response syndrome, with sepsis-associated acute kidney injury (SA-AKI) being a common complication. Insulin resistance (IR) is closely related to the stress response, inflammatory response, and severity of critical illness. The triglyceride-glucose body mass index (TyG-BMI) is a valuable tool for assessing IR.
