Particulate matter (PM, diameter < 10 μm) and Diesel exhaust particles (DEP) exposure can cause severe respiratory disorders. This investigation explored the protective effects of Reliea® (RelA), combination of Codonopsis lanceolata and Chaenomeles sinensis extract, against airway inflammation related to PMD exposure. RelA treatment suppressed reactive oxygen species, nitric oxide release, cytokine expression (IL-6, IL-1β, iNOS, CXCL-2, MCP-1, and TNF-α), and the related inflammatory mechanisms in PM-induced alveolar macrophage cells.

Mathematical models are established tools to assist in outbreak response. They help characterise complex patterns in disease spread, simulate control options to assist public health authorities in decision-making, and longer-term operational and financial planning. In the context of vaccine-preventable diseases (VPDs), vaccines are one of the most-cost effective outbreak response interventions, with the potential to avert significant morbidity and mortality through timely delivery.

Background: The Objective Structured Clinical Examination (OSCE) is a cornerstone of medical education that uses a structured approach to assess clinical skills and competency. A well-designed checklist is essential to enhance the validity of OSCE exams. This study aimed to determine whether a clinically discriminatory checklist (CDC) improves the validity of the OSCE compared with an assessment using the thoroughness checklist (TC), with a particular focus on clinical reasoning.

Article Synopsis
  • Hepatic organoids (HOs) lack non-parenchymal cells, limiting their ability to model liver diseases, while multi-lineage liver organoids (mLOs) provide a more promising in vitro option due to their inclusion of various liver cell types.
  • The research shows that expanding cystic HOs from human pluripotent stem cells (hPSCs) can create a sustainable source for developing complex mLOs.
  • By optimizing the cAMP/Wnt/Hippo signaling pathways with small molecules during the creation and maturation of mLOs, researchers achieved structurally complex organoids that mimic liver functionality and respond effectively to fibrotic conditions.

  • * There is a lack of understanding of the sub-national variation of typhoid fever within the region, despite existing studies on country-level data.
  • * Researchers collected data from 229 reports on typhoid occurrences between 2000 and 2020 to analyze the disease's sub-national differences, aiming to inform and enhance intervention strategies.

Following an injury, the liver embarks on a process that drives the accumulation and reformation of the extracellular matrix, leading to hepatic fibrosis. Type I interferons (IFNs), including IFN-α and IFN-β, play a crucial role in averting chronic liver injury through the activation of IFN-stimulated genes (ISGs), which are instrumental in sculpting adaptive immunity. The role of 2'-5'-oligoadenylate synthase-like protein 1 (OASL1), an antiviral ISG, in the context of liver fibrosis remains to be elucidated.

Background: Korean red ginseng extract (KRGE) (Family: Araliaceae) is one of the most widely used traditional herbs in Asia. Multiple studies have shown that KRGE has anti-inflammation, anti-fatigue, anti-obesity, anti-oxidant, and anti-cancer effects.

Methods: Sprague-Dawley rats were divided into five groups for PTU-induced hypothyroidism and six groups for LT4-induced hyperthyroidism.

In this study, we compared antithrombotic activities of Korean Red Ginseng (KRG) and (CPC) on rats with induced thrombosis. Results indicate that KRG and CPC suppressed the arterial occlusion and the combination of KRG and CPC (KRG + CPC) treatment exhibited a synergistic effect with maximum reduction in thrombosis.

The inhabitation and parasitism of root-knot nematodes (RKNs) can be difficult to control, as its symptoms can be easily confused with other plant diseases; hence, identifying and controlling the occurrence of RKNs in plants remains an ongoing challenge. Moreover, there are only a few biological agents for controlling these harmful nematodes. In this study, sp.

Immunotherapy is likely the most remarkable advancement in lung cancer treatment during the past decade. Although immunotherapy provides substantial benefits, their therapeutic responses differ from those of conventional chemotherapy and targeted therapy, and some patients present unique immunotherapy response patterns that cannot be judged under the current measurement standards. Therefore, the response monitoring of immunotherapy can be challenging, such as the differentiation between real response and pseudo-response.

Sarcopenia refers to an age-related decrease in muscle mass and strength. The gut-muscle axis has been proposed as a promising target to alleviate muscle atrophy. The effect of KL-Biome-a postbiotic preparation comprising heat-killed KM-2, its metabolites, and an excipient (soybean powder)-on muscle atrophy was evaluated using dexamethasone (DEX)-induced atrophic C2C12 myoblasts and C57BL/6J mice.

Article Synopsis
  • - Cholera has significantly impacted Ethiopia between 2015 and 2023, with around 100,000 cases and over 1,000 deaths, highlighting the urgent need to study water, sanitation, and hygiene (WaSH) factors that contribute to outbreaks.
  • - A survey of 870 households in Shashemene Town revealed that access to safe drinking water, sanitation, and hygiene facilities was limited, and better WaSH conditions were linked to urban living, higher education, and wealth.
  • - The study found no significant link between basic WaSH access and cholera attack rates, suggesting that while improvements in WaSH are needed, further research with larger samples is required to better understand their relationship with cholera cases.

Background: In patients with esophageal squamous cell carcinoma (ESCC), accurately predicting a pathologic complete response (pCR) to preoperative chemoradiotherapy (PCRT) has the potential to enable an active surveillance strategy without esophagectomy. We aimed to establish a reliable multiparameter nomogram model that combines tumor characteristics, imaging modalities, and hematologic markers to predict pCR in patients with ESCC who underwent PCRT and esophagectomy.

Methods: We retrospectively reviewed the medical records of 457 patients with ESCC who received PCRT followed by esophagectomy between January 2005 and October 2020.

Background: Patients achieving pathological complete response (pCR) post-neoadjuvant chemoradiotherapy (nCRT) and surgery for locally advanced esophageal squamous cell carcinoma (ESCC) have a favorable prognosis. However, recurrence occurs in approximately 20-30% of all patients, with few studies evaluating their prognostic factors. We identified these prognostic factors, including inflammation-based markers, in patients with ESCC showing pCR after nCRT and surgery.

Article Synopsis
  • - The study identifies the interaction between BTLA on T cells and HVEM on regulatory T cells as a major factor limiting the effectiveness of T cell-based immunotherapies in tumors.
  • - High levels of BTLA in CAR T cells are linked to poorer treatment outcomes, prompting researchers to delete BTLA to improve the T cells' tumor-fighting abilities.
  • - By removing BTLA, T cells show enhanced signaling and function, suggesting that targeting the BTLA-HVEM interaction could boost the success of CAR T cell therapies.

Accurate simulation of different cell type interactions is crucial for physiological and precisedrug testing. Human tissue-resident macrophages are critical for modulating disease conditions and drug-induced injuries in various tissues; however, their limited availability has hindered their use inmodeling. Therefore, this study aimed to create macrophage-containing organoid co-culture models by directly incorporating human-induced pluripotent stem cell (hiPSC)-derived pre-macrophages into organoid and scaffold cell models.
