Neuroblastoma is a cancer that occurs due to abnormal development of the sympathetic nervous system. The dysregulation of miR-9 and miR-222 plays a crucial role in neuroblastoma development. These microRNAs have a significant relationship with PTEN, caspase-9, and MMP14, which can potentially form the basis for the specific diagnosis and treatment of this disease.

This study has introduced a medicine to treat dogs infested with scabies (variants of Demodex, Sarcoptes, Psoroptes, Otodectes, etc.).

- The study investigates the diagnostic accuracy of ultrasonography for intussusception in children, which can be difficult to diagnose due to nonspecific clinical signs and unclear patient histories.
- A systematic review of 37 studies found that ultrasonography has high pooled sensitivity (0.96) and specificity (0.97) for detecting intussusception.
- Additionally, there was no significant difference in diagnostic performance between point-of-care ultrasound (POCUS) and radiologist-performed ultrasound (RADUS).
Recently, mesenchymal stem/stromal cells (MSCs) therapy has become an emerging therapeutic modality for the treatment of inflammatory bowel disease (IBD), given their immunoregulatory and pro-survival attributes. MSCs alleviate dysregulated inflammatory responses through the secretion of a myriad of anti-inflammatory mediators, such as interleukin 10 (IL-10), transforming growth factor-β (TGFβ), prostaglandin E2 (PGE2), tumor necrosis factor-stimulated gene-6 (TSG-6), etc. Indeed, MSC treatment of IBD is largely carried out through local microcirculation construction, colonization and repair, and immunomodulation, thus alleviating diseases severity.

- * A thorough search of existing literature resulted in 26 relevant studies, revealing that MRI has a high sensitivity of 92% and specificity of 98% for diagnosing AA in this population.
- * The findings suggest that MRI should be the preferred imaging technique for suspected AA in pregnant women, particularly when ultrasound results are unclear, potentially reducing unnecessary surgeries.
Metal organic frameworks (MOFs) have received a lot of attention in the research community due to their unique physical properties, which make them ideal materials for targeted drug delivery systems. In this paper, we describe the synthesis of a non-toxic La-based MOF with 3,4-dihydroxycinnamic acid (3,4-DHCA) as a linker. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), nitrogen adsorption-desorption measurements, and X-ray powder diffraction (XRD) have all been used to characterize it thoroughly.

- Environmental pollution is a critical issue, and nanotechnology is emerging as a promising solution through the use of nanoparticles for pollutant removal.
- This study focused on the synthesis of Nickel oxide nanoparticles (NiO NPs) using a green method with nickel nitrate and natural extract, resulting in fine cubic structures with an average size of 54-58 nm.
- The synthesized NiO NPs showed impressive photocatalytic activity (90.2%) for degrading acid orange 7 dye under visible light, indicating their potential effectiveness in environmental cleanup.
