The present study highlights/demonstrates facile synthesis of β-Glucan nanoparticles (β-GluNPs) that can be used in the prevention of breast cancer and other infectious diseases. Moreover, this method is inexpensive and shows effectivity towards different biological applications. Further, the characterization of synthesized β-GluNPs was exclusively confirmed through UV-Vis spectroscopy, Fourier transform infrared spectroscopy (FT-IR), dynamic light scattering (DLS), zeta potential, scanning electron microscopy (SEM), high resolution-transmission electron microscopy (HR-TEM), and X-ray powder diffraction (XRD) analysis. The synthesized β-GluNPs were further confirmed by FT-IR spectroscopy. The HR-TEM results demonstrated that the formation of polydispersed nanoparticles with a mean size of 20 ± 5 nm. The hydrostatic zeta potential was - 22.7 mV, which indicated their colloidal stability. The XRD pattern revealed the crystalline nature of the nanoparticles. Besides, β-GluNPs showed better antibacterial activity against the tested pathogens. The apoptosis and DNA fragmentation observed to be IC 42.5 µg/ml of the β-GluNPs. The DNA fragmentation assay indicated the selective inhibition of the MCF-7 cell line by DNA damage. Hence, the study reports that the β-GluNPs have a potential to be used as a promising alternative drug against human breast cancer.

Both women and men are now confronted with the grave threat of cancers caused by the human papillomavirus (HPV). It is estimated that 80% of women may encounter HPV over their lives. In the preponderance of cases involving anal, head and neck, oral, oropharyngeal, penile, vaginal, vulvar, and cervical malignancies, high-risk HPV (HR-HPV) is the causative agent.

Background: The microbes residing in ruminant gastrointestinal tracts play a crucial role in converting plant biomass to volatile fatty acids, which serve as the primary energy source for ruminants. This gastrointestinal tract comprises a foregut (rumen) and hindgut (cecum and colon), which differ in structures and functions, particularly with respect to feed digestion and fermentation. While the rumen microbiome has been extensively studied, the cecal microbiome remains much less investigated and understood, especially concerning the assembling microbial communities and overriding pathways of hydrogen metabolism.

Background: Many studies have found more severe COVID-19 outcomes in migrants and ethnic minorities throughout the COVID-19 pandemic, while recent evidence also suggests higher risk of longer-term consequences. We studied the risk of a long COVID diagnosis among adult residents in Sweden, dependent on country of birth and accounting for known risk factors for long COVID.
Methods: We used linked Swedish administrative registers between March 1, 2020 and April 1, 2023, to estimate the risk of a long COVID diagnosis in the adult population that had a confirmed COVID-19 infection.

Background: Cancer remains a leading cause of death worldwide. Environmental factors, specifically endocrine-disrupting chemicals (EDCs), like phthalates, are increasingly being linked to cancer development. Phthalates, widely used in consumer products, can activate the aryl hydrocarbon receptor (AhR).

Background: Hepatic glycogen storage diseases (GSD) are inborn errors of metabolism with abnormal storage or utilization of glycogen, a complex disease with significant genetic heterogeneity and similar clinical manifestations. This study aimed to describe the gastrointestinal symptoms and endoscopic features of hepatic GSD, including types Ia, Ib, III, VI, and IX, to provide evidence for etiology and treatment.
Methods: A national cohort survey questionnaire was distributed to patients diagnosed with GSD type Ia, Ib, III, VI, and IX through genetic testing or their parents in mainland China in May 2022.
