Preclinical evaluation of a new technetium-99m labeled neurotensin analogue for NTSR1 targeted radionuclide imaging.

Neurotensin is a regulatory peptide that can act as a growth factor on different types of normal and cancerous cells. Binding of Neurotensin to relevant receptors leads to cell proliferation, survival, migration and invasion by changing intracellular enzyme activity. Therefore, the design of a neurotensin-based radiopeptide plays an important role in targeted imaging or therapy of neurotensin receptor-positive tumors.

Technetium-99m radiolabeling of graphene quantum dots (GQDs) as a new probe for glioblastoma tumor imaging.

Purpose: Cancer diagnosis involves a multi-step process. Accurate identification of the tumor, staging and development of cancer cells is crucial for selecting optimal treatments to minimize disease recurrence. Quantum dots (QDs) represent an exciting class of fluorescent nanoprobes in molecular detection and targeted tumor imaging.

Are implant-based treatments considered viable for patients with focal or florid cemento-osseous dysplasia? A systematic review.

Background: Focal and florid cemento-osseous dysplasia are benign fibro-osseous lesions affecting the quality and quantity of the jawbones. This study aimed to determine the viability of implant-based approaches in the affected patients.

Main Text: Different scientific databases, including PubMed/MEDLINE, Scopus, Web of Science, Embase, the Cochrane Library, and Google Scholar, were searched until October 8, 2023, using a pre-determined search strategy.

The elemental fingerprint as a potential tool for tracking the fate of real-life model nanoplastics generated from plastic consumer products in environmental systems.

Metals and metalloids are widely used in producing plastic materials as fillers and pigments, which can be used to track the environmental fate of real-life nanoplastics in environmental and biological systems. Therefore, this study investigated the metal and metalloids concentrations and fingerprint in real-life model nanoplastics generated from new plastic products (NPP) and from environmentally aged ocean plastic fragments (NPO) using single particle-inductively coupled plasma-mass spectrometry (SP-ICP-TOF-MS) and transmission electron microscopy coupled with energy dispersive X-ray spectroscopy (TEM-EDX). The new plastic products include polypropylene straws (PPS), polyethylene terephthalate bottles (PETEB), white low-density polyethylene bags (LDPEB), and polystyrene foam shipping material (PSF).

Life cycle analysis of the wastewater treatment system in Zabol Industrial Town: Environmental impacts, energy demand, and greenhouse gas emissions.

Use of effective environmental remediation facilities represents a crucial strategy for water reclamation and addressing the challenges of water scarcity. The objective of this study was to assess the wastewater treatment system (WWTS) in Zabol Industrial Town using the life cycle assessment method. Primary data, collected annually for a functional unit of 1 m of wastewater treatment, were subjected to analysis using the ReCiPe, Cumulative Energy Demand, and Intergovernmental Panel on Climate Change (IPCC) methods.
