The presence of pesticide residues in textiles poses a risk to human health. We established a robust and high-throughput liquid chromatography-tandem mass spectrometry method for the determination of 115 pesticide residues in textiles. In this study, we evaluated high-performance liquid chromatography-tandem mass spectrometry conditions and sample extraction methods, including separation performance of different columns, mass conditions, extraction solvent, and extraction time.

The epithelial-mesenchymal transition (EMT) assists in the acquisition of invasiveness, relapse, and resistance in non-small cell lung cancer (NSCLC) and can be caused by the signaling of transforming growth factor-β1 (TGF-β1) through Smad-mediated or Smad-independent pathways. (-)-Epigallocatechin-3-gallate (EGCG), a multifunctional cancer-preventing bioconstituent found in tea polyphenols, has been shown to repress TGF-β1-triggered EMT in the human NSCLC A549 cell line by inhibiting the activation of Smad2 and Erk1/2 or reducing the acetylation of Smad2 and Smad3. However, its impact on the Smad-independent pathway remains unclear.

Three new pyridine derivatives, irpelactedines A-C (1-3), and a new furan derivative, irpelactedine D (5), along with two structurally related known compounds, irpexidine A (4) and 5-carboxy-2-furanpropanoic acid (6), were isolated from the medicinal fungus Irpex lacteus SY1002. Their structures were elucidated through NMR and mass spectral analyses, combined with density functional theory calculations of ECD data. Evaluation of angiotensin-converting enzyme (ACE) inhibitory activity revealed that compounds 1 and 3 displayed moderate inhibition, with IC50 values of 31.

Objective: Cystic fibrosis (CF) is a clinical entity defined by aberrant chloride (Cl) ion transport causing downstream effects on mucociliary clearance (MCC) in sinonasal epithelia. Inducible deficiencies in transepithelial Cl transport via CF transmembrane conductance regulator (CFTR) has been theorized to be a driving process in recalcitrant chronic rhinosinusitis (CRS) in patients without CF. We have previously identified that brief exposures to bacterial lipopolysaccharide (LPS) in mammalian cells induces an acquired dysfunction of CFTR in vitro and in vivo.

Changes in the microstructure of the aortic wall precede the progression of various aortic pathologies, including aneurysms and dissection. Current clinical decisions with regards to surgical planning and/or radiological intervention are guided by geometric features, such as aortic diameter, since clinical imaging lacks tissue microstructural information. The aim of this proof-of-concept work is to investigate a non-invasive imaging method, diffusion tensor imaging (DTI), in ex vivo aortic tissue to gain insights into the microstructure.

Vasculogenic mimicry (VM) represents a novel form of angiogenesis discovered in numerous malignant tumours in recent years. Unlike traditional angiogenesis, VM facilitates tumour blood supply independently of endothelial cells by enabling tumour cells to form functional vascular networks. This phenomenon, where tumour cells replace endothelial cells to form tubular structures, plays a pivotal role in tumour growth and metastasis.

Immigrants and refugees in the United States often face significant barriers in accessing social services, including mental health support, legal assistance, ESL or related education, housing, vocational training, workforce resources, transportation, and citizenship support. This article explores the strengths and challenges of community-based organizations welcoming centers (CBO WC) in Illinois that serve these populations, including people with disabilities, in culturally appropriate and inclusive ways. The Immigrant and Refugee-Led Capacity Development Network of Illinois, based at the University of Illinois Chicago, collaborated with the state's Office of Welcoming Centers to explore the service capacities of 17 CBO grantees.

If "no ought from is," how can bioethics be empirical? Despite the widespread recognition that we can integrate empirical and normative, Hume's Law is still often claimed to pose logical limitations to empirical bioethics. Is Hume's Law a valid argument against empirical bioethics? I argue that we have reasons to answer no. First, I outline and reject two unverified assumptions: that Hume' s Law, the fact-value distinction, and the naturalistic fallacy are roughly the same thing, and that Hume's Law is an undisputed meta-ethical principle which dictates how to formulate normative statements.

Background: Breast cancer screening (BCS) inequities are evident at national and local levels, and many health systems want to address these inequities, but may lack data about contributing factors. The objective of this study was to inform health system interventions through an exploratory analysis of potential multilevel contributors to BCS inequities using health system data.
Methods: The authors conducted a cross-sectional analysis within a large academic health system including 19,774 individuals who identified as Black (n = 1445) or White (n = 18,329) race and were eligible for BCS.

Background: To date, 11 DNA polymerase epsilon (POLE) pathogenic variants have been declared "hotspot" mutations. Patients with endometrial cancer (EC) characterized by POLE hotspot mutations (POLEmut) have exceptional survival outcomes. Whereas international guidelines encourage deescalation of adjuvant treatment in early-stage POLEmut EC, data regarding safety in POLEmut patients with unfavorable characteristics are still under investigation.

Due to their superior physicochemical features, chitosan thermosensitive hydrogels are multipurpose platforms that are frequently used in the biomedical industry. Many investigations have been conducted recently to modify their pore dimensions, expansion, biodegradability, stimulus-reaction characteristics, and other characteristics in order to better tailor them to the complex craniofacial tissues. They have been the focus of various studies that have attempted to load biological cargos for therapeutic and regenerative uses in the oro-facial tissues.

Osteochondral damage, caused by trauma, tumors, or degenerative diseases, presents a major challenge due to the limited self-repair capacity of the tissue. Traditional treatments often result in significant trauma and unpredictable outcomes. Recent advances in bone/cartilage tissue engineering, particularly in scaffold materials and fabrication technologies, offer promising solutions for osteochondral regeneration.

Background And Aims: Maternal obesity increases the risk of the paediatric form of metabolic dysfunction-associated steatotic liver disease (MASLD), affecting up to 30% of youth, but the developmental origins remain poorly understood.
Methods: Using a Japanese macaque model, we investigated the impact of maternal Western-style diet (mWSD) or chow diet followed by postweaning WSD (pwWSD) or chow diet focusing on bile acid (BA) homeostasis and hepatic fibrosis in livers from third-trimester fetuses and 3-year-old juvenile offspring.
Results: Juveniles exposed to mWSD had increased hepatic collagen I/III content and stellate cell activation in portal regions.

Background: With a decline of 17β-estradiol (E2) at menopause, E2 has been implicated in the accompanied loss of skeletal muscle mass and strength. We aimed at characterizing transcriptomic responses of skeletal muscle to E2 in female mice, testing the hypothesis that genes and pathways related to contraction and maintenance of mass are differentially expressed in ovariectomized mice with and without E2 treatment.
Methods: Soleus and tibialis anterior (TA) muscles from C57BL/6 ovariectomized mice treated with placebo (OVX) or E2 (OVX + E2) for 60 days, or from skeletal muscle-specific ERα knockout (skmERαKO) mice and wild-type littermates (skmERαWT), were used for genome-wide expression profiling, quantitative real-time PCR and immunoblotting.
