Optimising Pirfenidone Dosage Regimens in Idiopathic Pulmonary Fibrosis: Toward a Guide for Personalised Treatment.

Idiopathic Pulmonary Fibrosis (IPF) is a chronic respiratory disorder for which pirfenidone is the recommended first-line anti-fibrotic treatment. While pirfenidone has demonstrated efficacy in slowing the progression of IPF, its use is associated with several challenges and unresolved issues that impact patient outcomes. Pirfenidone administration can result in gastrointestinal side effects, photosensitivity reactions, and significant drug interactions, particularly in patients with hepatic impairment.

A pan-immune panorama of bacterial pneumonia revealed by a large-scale single-cell transcriptome atlas.

Bacterial pneumonia is a significant public health burden, contributing to substantial morbidity, mortality, and healthcare costs. Current therapeutic strategies beyond antibiotics and adjuvant therapies are limited, highlighting the need for a deeper understanding of the disease pathogenesis. Here, we employed single-cell RNA sequencing of 444,146 bronchoalveolar lavage fluid cells (BALFs) from a large cohort of 74 individuals, including 58 patients with mild (n = 22) and severe (n = 36) diseases as well as 16 healthy donors.

Sea-Island Micelle Structured Hydrogel Scaffold: A Dual-Action Approach to Combat Cartilage Damage under RA Conditions.

Rheumatoid arthritis (RA) is a common autoimmune joint disease characterized by persistent synovial inflammation and cartilage damage. The current clinical treatments primarily utilize drugs such as triptolide (TP) to address inflammation, yet they are unable to directly repair damaged cartilage. Furthermore, the persistent inflammation often undermines the effectiveness of traditional cartilage repair strategies, preventing them from achieving optimal outcomes.

Examination of immunohistochemical of the effects of flattened and unflattened radiotherapy beams in nude mice breast cancer xenografts.

Purpose: The aim of this study was to investigate the radiobiological effects underlying the inhibition of breast cancer (BCa) following radiotherapy in nude mice models, and to evaluate the impact of changes in immunohistochemical parameters induced by FF and FFF beams.

Materials And Methods: The study included thirty-six adult nude mouse models, which were randomly assigned to five groups: control (G1), breast cancer (BCa) (G2), FF-400 MU/min (G3), FFF-1100 MU/min (G4), and FFF-1800 MU/min (G5). The control group received neither radiation nor treatment, while the BCa group had a cancer model without radiation.

BRISC-Mediated PPM1B-K63 Deubiquitination and Subsequent TGF-β Pathway Activation Promote High-Fat/High-Sucrose Diet-Induced Arterial Stiffness.

Background: Metabolic syndrome heightens cardiovascular disease risk primarily through increased arterial stiffness. We previously demonstrated the involvement of YAP (Yes-associated protein) in high-fat/high-sucrose diet (HFHSD)-induced arterial stiffness via modulation of PPM1B (protein phosphatase Mg/Mn-dependent 1B)-lysine63 (K63) deubiquitination. In this study, we aimed to elucidate the role and mechanisms underlying PPM1B deubiquitination in HFHSD-induced arterial stiffness.

Rapid screening of esophageal squamous cell carcinoma by near-infrared spectroscopy combined with aquaphotomics.

Esophageal cancer (EC), the fifth most common cause of cancer-related mortality in China, poses a significant threat to public health. Among the pathological types, esophageal squamous cell carcinoma (ESCC) is predominant, comprising approximately 90 % of cases. Screening is crucial for early detection, diagnosis and treatment, thereby reducing ESCC mortality.

[HPLC-Q-TOF-MS/MS and network pharmacology reveal absorbed components of Bufei Pills, potential in treating respiratory disorders, and mechanism in recovery stage of COVID-19].

For the in vivo distribution study, rats were administrated with Bufei Pills, and the absorbed components were analyzed by HPLC-Q-TOF-MS/MS. The results showed that 56 components were present in the rat serum, including neocyclomorusin, asterinin A, neoisostegane, goimisin R, and frehmaglutoside H.

[Proteomics in prevention and treatment of post-myocardial infarction heart failure diseases with traditional Chinese medicine].

Myocardial infarction(MI) is a cardiovascular disease with high disability and mortality rates in clinical practice, which can subsequently develop into complications such as heart failure(HF) or cardiac rupture. Proteomics can track changes in relevant functional molecules during the occurrence and progression of diseases from an overall, molecular, systematic, and flux perspectives. Utilizing proteomic techniques to deeply explore the functional targets, molecular mechanisms, and network effects of MI and HF can aid in early diagnosis, early warning, and drug treatment of these diseases.

Transcriptomic and proteomic sequencing unveils the role of vitamin D and metabolic flux shifts in the induction of human hepatic organoids.

Background: Hepatic organoids (HOs), validated through comparative sequencing with human liver tissues, are reliable models for liver research. Comprehensive transcriptomic and proteomic sequencing of HOs throughout their induction period will enhance the platform's utility, aiding in the elucidation of liver development's molecular mechanisms.

Methods: We developed hepatic organoids (HOs) from embryonic stem cells (ESCs) through a de novo induction protocol, mimicking the stages of fetal liver development: ESCs to definitive endoderm (DE), then to foregut (FG), hepatoblasts (HB), and finally to HOs stage 1 (HO1), culminating in self-organizing HOs stage 2 (HO2) via dissociation and re-inoculation.

Genetic Downregulation of GABA Receptors from Oligodendrocyte Precursor Cells Protects Against Demyelination in the Mouse Spinal Cord.

GABAergic signaling and GABA receptors play crucial roles in regulating the physiology of oligodendrocyte-lineage cells, including their proliferation, differentiation, and myelination. Therefore, they are promising targets for studying how spinal oligodendrocyte precursor cells (OPCs) respond to injuries and neurodegenerative diseases like multiple sclerosis. Taking advantage of the temporally controlled and cell-specific genetic downregulation of GABA receptors from OPCs, our investigation addresses their specific influence on OPC behavior in the gray and white matter of the mouse spinal cord.

Background: The variability in patients' risk of oral mucositis (OM) has been, in part, attributed to differences in host genomics. The aim better define the role of genomics as an OM risk by investigating the association between genetic variants and the presence and severity of OM in pediatric patients with osteosarcoma (OS) undergoing chemotherapy (CT).

Methods: A longitudinal observational retrospective study was conducted.

Epigenomic and clinical analyses of striatal DAT binding in healthy individuals reveal well-known loci of Parkinson's disease.

Background: Striatal dopamine transporter (DAT) binding is a sensitive and specific endophenotype for detecting dopaminergic deficits across Parkinson's disease (PD) spectrum. Molecular and clinical signatures of PD in asymptomatic phases help understand the earliest pathophysiological mechanisms underlying the disease. We aimed to investigate whether blood epigenetic markers are associated with inter-individual variation of striatal DAT binding among healthy elderly individuals.

Ultra-rapid and sensitive detection of African swine fever virus using multiple cross displacement amplification combined with nanoparticle-based lateral flow biosensor.

African swine fever (ASF) is a devastating disease that can kill almost all infected pigs, causing great damage to the pig industry and destabilizing the global economy. Here, we developed a specific assay that combined multiple cross-displacement amplification (MCDA) with a nanoparticle-based lateral flow biosensor (LFB) for early and rapid identification of the African swine fever virus (ASFV-MCDA-LFB). We first designed a set of MCDA primers to recognize 10 different regions of the target ASFV gene.
