The Imaging Science Subsystem onboard the Cassini spacecraft recorded numerous high-quality images of Jupiter and Saturn at various wavelengths, from ultraviolet to near-infrared, during its 20-year mission from 1997 to 2017. Using these images, we have developed global maps of Jupiter and Saturn across multiple wavelengths. These maps reveal the global atmospheric structures of Jupiter and Saturn, offering a comprehensive tool to study the physical and dynamic processes of these atmospheric systems on a global scale.

Photodynamic therapy (PDT) and photothermal therapy (PTT) have emerged as promising treatment options, showcasing immense potential in addressing both oncologic and nononcologic diseases. Single-component organic phototherapeutic agents (SCOPAs) offer advantages compared to inorganic or multicomponent nanomedicine, including better biosafety, lower toxicity, simpler synthesis, and enhanced reproducibility. Nonetheless, how to further improve the therapeutic effectiveness of SCOPAs remains a challenging research area.

Introduction: Traditional extraocular electrical stimulation typically produces diffuse electric fields across the retina, limiting the precision of targeted therapy. Temporally interfering (TI) electrical stimulation, an emerging approach, can generate convergent electric fields, providing advantages for targeted treatment of various eye conditions.

Objective: Understanding how detailed structures of the retina, especially the optic nerve, affects electric fields can enhance the application of TI approach in retinal neurodegenerative and vascular diseases, an essential aspect that has been frequently neglected in previous researches.

Apelin, an endogenous ligand of G protein-coupled receptor APJ, is widely distributed in the central nervous system (CNS). It can be divided into such subtypes as Apelin-13, Apelin-17, and Apelin-36 as they have different amino acid structures. All Apelin is widely studied as an adipokine, showing a significant protective effect through regulating apoptosis, autophagy, oxidative stress, angiogenesis, inflammation, and other pathophysiological processes.

Little is known about the population-based mismatch between phenotypic and genetic BMI (BMI-PGM) and its association with type 2 diabetes. We therefore used data from the China Kadoorie Biobank and UK Biobank and calculated BMI-PGM for each participant as the difference between the percentile for adjusted BMI at baseline and the percentile for adjusted polygenic risk score for BMI. Participants were categorized into discordantly low (BMI-PGM< the 1st quartile), concordant (the 1st quartile ≤BMI-PGM View Article and Find Full Text PDF

Background: Little evidence is available on the long-term health effects of nitrogen dioxide (NO) in low-income and middle-income populations.

Article Synopsis
  • - The study investigates the link between muscle mass, strength, quality, and respiratory diseases specifically in a Chinese population, using data from the China Kadoorie Biobank.
  • - Researchers followed 17,510 participants over approximately 4.82 years and found that those with low grip strength and poor arm muscle quality had significantly higher risks of developing respiratory diseases, with hazard ratios of 1.31 and 1.25, respectively.
  • - The results suggest that low grip strength and arm muscle quality are more predictive of respiratory disease risk compared to overall muscle mass, emphasizing their importance as health indicators.

Plasma proteomics could enhance risk prediction for multiple diseases beyond conventional risk factors or polygenic scores (PS). To assess utility of proteomics for risk prediction of ischemic heart disease (IHD) compared with conventional risk factors and PS in Chinese and European populations. A nested case-cohort study measured plasma levels of 2923 proteins using Olink Explore panel in ~ 4000 Chinese adults (1976 incident IHD cases and 2001 sub-cohort controls).

  • - The study investigates the link between environmental tobacco smoke (ETS) and esophageal cancer in high-risk groups in Jiangsu Province, China, analyzing data from nearly 3,000 cancer cases and over 8,000 control participants.
  • - Findings reveal that exposure to ETS increases the risk of esophageal cancer, with a notable association among non-smokers, particularly men in workplaces and women at home, showing adjusted odds ratios indicating higher risk levels.
  • - The research highlights the need for stronger anti-tobacco public health efforts in China, recommending the creation of tobacco-free environments in both workplaces and homes to mitigate the impacts of ETS.

  • Current therapies for systemic lupus erythematosus (SLE) are often not very effective, leading researchers to focus on CD132, a key component in inflammatory responses related to the disease.
  • A new humanized anti-CD132 monoclonal antibody, 2D4, shows promise by effectively blocking specific inflammatory signals, suppressing T and B cell activity, and reducing inflammation in mouse models of lupus.
  • Compared to the existing treatment Belimumab, 2D4 demonstrated better results in improving inflammation and kidney function, suggesting strong potential for clinical use in SLE and other autoimmune disorders.

  • The study investigated the impact of meal-replacement (MR) drinking on the risk of dying from various causes, including general mortality, cardiovascular and cerebrovascular diseases, and cancer, using data from 6770 adults aged 20 and older.
  • Results showed that individuals who drank MR daily or weekly had a significantly higher risk of all-cause mortality compared to those who seldom drank it, with effects being particularly stronger in females.
  • The findings suggest that regularly consuming meal replacements could potentially contribute to increased mortality risk, highlighting the need for caution in their use.

  • This study explored how consuming two types of preserved vegetables in China (salted and sour pickled) relates to the risk of gastrointestinal cancers, including oesophageal, stomach, and colorectal cancers.
  • The research analyzed data from over 510,000 adults, assessing their vegetable intake and monitoring cancer development over 14 years.
  • Results indicated that salted vegetable consumption is linked to a higher risk of stomach cancer, while sour pickled vegetables are associated with an increased risk of oesophageal cancer, suggesting that reducing preserved vegetable intake may help lower the risk of these cancers.

  • The prevalence of COPD (Chronic Obstructive Pulmonary Disease) in Chinese individuals over 50 is significantly higher than in younger adults, but the specific risk factors for this older age group were previously unclear.
  • Recent findings show that the COPD prevalence is 12.8% for males and 5.7% for females in this age group, with identified risk factors including cigarette smoking, family history of respiratory issues, and childhood respiratory problems.
  • These insights can aid healthcare providers and the public in recognizing those at greater risk for COPD, allowing for more effective prevention and intervention strategies.

  • Recent guidelines suggest that individuals with prehypertension (130/80 to 139/89 mm Hg) should consider antihypertensive treatment; this study assesses the cost-effectiveness of three interventions: salt substitution, antihypertensive drugs, and their combination in Chinese adults.
  • A Markov cohort model was used to estimate the impact of these interventions on cardiovascular disease events, costs, and quality-adjusted life years (QALYs), utilizing data from the China Kadoorie Biobank.
  • The findings indicate that salt substitution is the most cost-effective strategy for prehypertensive individuals starting at age 40, while a combination intervention is best for those at high cardiovascular risk; beginning these interventions at younger ages can lead to more

In the secondary injury stage of spinal cord injury, mitochondrial dysfunction leads to decreased ATP production, increased ROS production, and activation of the mitochondria-mediated apoptosis signaling pathway. This ultimately intensifies neuronal death and promotes the progression of the injury. Apelin, a peptide produced by the APLN gene, has demonstrated promise in the treatment of spinal cord injury.
