From Anatase TiO Nano-Cuboids to Nano-Bipyramids: Influence of Particle Shape on the TiO Photocatalytic Degradation of Emerging Contaminants in Contrasted Water Matrices.

Water pollution, resulting from industrial effluents, agricultural runoff, and pharmaceutical residues, poses serious threats to ecosystems and human health, highlighting the need for innovative approaches to effective remediation, particularly for non-biodegradable emerging pollutants. This research work explores the influence of shape-controlled nanocrystalline titanium dioxide (TiO NC), synthesized by a simple hydrothermal method, on the photodegradation efficiency of three different classes of emerging environmental pollutants: phenol, pesticides (methomyl), and drugs (sodium diclofenac). Experiments were conducted to assess the influence of the water matrix on treatment efficiency by using ultrapure water and stormwater (basic) collected from an urban drainage system as matrices.

Nasopharyngeal carcinoma with unusual metastatic spread to the spine and meninges: a case report with literature review.

Nasopharyngeal carcinoma (NPC) is an epithelial malignancy commonly associated with Epstein-Barr virus infection. While bone, liver, and lung metastases are well-documented, central nervous system (CNS) involvement, particularly spinal and meningeal metastases, is extremely rare. We present a 41-year-old male with nasal obstruction and diplopia, diagnosed with locally advanced NPC.

On the Synthesis of Graphene Oxide/Titanium Dioxide (GO/TiO) Nanorods and Their Application as Saturable Absorbers for Passive Q-Switched Fiber Lasers.

We report passively Q-switched pulse operation through an erbium-doped fiber laser (EDFL) utilizing graphene oxide/titania (GO/TiO) nanorods as a saturable absorber. The GO/TiO nanorods were fabricated using a Sol-gel-assisted hydrothermal method. The optical and physical characterization of the GO/TiO was then characterized using a field-emission-scanning electron microscope (FE-SEM), energy-dispersive X-ray spectroscopy (EDS), and diffuses reflectance spectroscopy (DRS).

Using point-of-care ultrasound to determine incidence of deep vein thrombosis after right-sided radiofrequency catheter ablation.

Introduction: Femoral venous access is routinely used for radiofrequency catheter ablation (RFA) procedures. Deep vein thrombosis (DVT), which is often sub-clinical, is uncommon following RFCA. Point-of-care ultrasound (POCUS) is a cost-effective way to diagnose DVT.
