The immunomodulatory effects and excellent tolerability of polysaccharides make them optimal candidates for pulmonary vaccine adjuvants. Yet, the structure-immunostimulatory activity relationship of polysaccharides remains unrevealed. Here, we developed nanovaccines decorated with four polysaccharides of distinct structures─hyaluronic acid (HA), pectin (PC), chondroitin sulfate (SC), and heparan sulfate (SH)─all sharing similar particle sizes and zeta potential.

Sialylation, a key post-translational modification essential for protein function, is regulated by steroid hormones, along with other glycosylations like fucosylation. These modifications influence tumor growth and metastasis by modulating immune activation. MicroRNAs (miRNAs), crucial in gene expression, affect sialylation and are emerging as promising biomarkers in breast cancer, though their prognostic value remains unclear.

Maize seedlings in cold regions and high latitude often face abiotic stress. As a result, weak seedlings affect maize production, The commonly used seed coating agents in production are mainly to prevent biological stress of pests and diseases, and have little effect on seedling vigor and abiotic resistance. In this experiment, the combination of graphene oxide (GO) and seed coating agent can effectively prevent pests and diseases and increase the growth of seedlings.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spread rapidly, leading to an Omicron outbreak in Shanghai in mid-December after adjustments to the Coronavirus Disease 2019 (COVID-19) control strategy. To investigate the impact of COVID-19 infection among hypothyroid patients, we gathered data on the hypothyroid outpatients with COVID-19 infection during this time at the Thyroid Disease Center (TDC) of Shanghai Central Hospital. Patients were divided into two groups based on whether their hypothyroidism was caused by Hashimoto's Thyroiditis (HT): the HT and the non-HT group.

Article Synopsis
  • Forest succession is a key method for ecosystem restoration, significantly influenced by soil microbes that regulate carbon cycling.
  • The study focused on the Changbai Mountains in China, showing how soil organic carbon (SOC) affects the structure and assembly of microbial communities as forests evolve.
  • Results indicated that as forests succeed, the composition of bacterial and fungal communities changes, with labile SOC playing a crucial role in these microbial interactions and diversity, emphasizing its importance in forest function research.

Alcoholic steatohepatitis (ASH) is a liver disease characterized by steatosis, inflammation, and necrosis of the liver tissue as a result of excessive alcohol consumption. Pregnane X receptor (PXR) is a xenobiotic nuclear receptor best known for its function in the transcriptional regulation of drug metabolism and disposition. Clinical reports suggested that the antibiotic rifampicin, a potent human PXR activator, is a contraindication in alcoholics, but the mechanism was unclear.

Background: In China, spouses of patients with advanced cancer have reported experiencing psychological distress. However, little attention has been paid to the positive psychological health trajectories of these caregivers, particularly regarding their resilience and the factors influencing its development over time.

Purpose: To examine the trajectories of resilience in Chinese spousal caregivers over a nine-month post-treatment period and to identify the basic characteristics associated with these trajectory patterns.

  • The study aims to explore the link between fever and the occurrence of meconium-stained amniotic fluid (MSAF) in pregnant women during the COVID-19 pandemic, comparing data from women with fever to those without.
  • Out of 400 pregnant women analyzed, 17.25% exhibited MSAF, with increased prevalence (21.85%) in fever-pregnant women, indicating a statistically significant association between fever and MSAF risk.
  • Furthermore, COVID-19 infection notably raised the odds of developing MSAF by 2.567 times, while abnormal fetal heart monitoring and gestational age emerged as independent risk factors, highlighting the need for careful monitoring of these conditions in at-risk pregnant women.

SARS-CoV-2 ancestral strain-induced immune imprinting poses great challenges to updating vaccines for new variants. Studies showed that repeated Omicron exposures could override immune imprinting induced by inactivated vaccines but not mRNA vaccines, a disparity yet to be understood. Here, we analyzed the immune imprinting alleviation in inactivated vaccine (CoronaVac) cohorts after a long-term period following breakthrough infections (BTI).
