PURPOSE Despite advances in multimodality management of brain metastases, local progression following stereotactic radiosurgery (SRS) can occur. Often, surgical resection is favored, as it frequently provides immediate symptom relief as well as pathological characterization of any residual tumor. Should the pathological specimen contain viable tumor cells, further radiation therapy is an option...

Lead is a common environmental toxic element for almost all biological systems. The nervous system is the primary target for the lead exposure. In the past few years, increasing considerations have been given to investigate the interaction occurring between toxic metals and some essential metals including Se and Zn with Pb. It has been shown that some trace elements could reverse the toxicity o...

teucrium polium l. (tp) is widely used in traditional medicine of many countries including iran. there are various reports about pharmacological properties of tp such as calcium antagonist, anti- ulcer, anti – diabetic. there are a few reports about possible toxicological effects of this plant. in the present study we designed to evaluate the subchronic toxicity of teucrium polium total extract...

objective(s) ocimum basilicum l. is widely used in folk medicine of many countries including iran. both o. basilicum and its oil extract have received considerable attention for their potential medicinal properties, but there are a few reports about possible toxicity of this plant. therefore, in the present study, acute and subchronic toxicity of o. basilicum hydroalcohlic extract have been eva...

Dendrimers are highly customizable nanopolymers with qualities that make them ideal for drug delivery. The high binding affinity of biotin/avidin provides a useful approach to fluorescently label synthesized dendrimer-conjugates in cells and tissues. In addition, biotin may facilitate delivery of dendrimers through the blood-brain barrier (BBB) via carrier-mediated endocytosis. The purpose of t...

One of the most important scientific disciplines is determining toxicity heavy metals in freshwater, and there a rising concern about development methodologies for identifying toxic effects aquatic creatures. To test efficacy this approach, an experimental study was conducted on fish Cyprinus carpio from pond Bengaluru, Karnataka. Surface bioaccumulation mercury lead studies using Scanning Elec...

BACKGROUND Kim et al. report two patients with melanoma metastases to the brain that responded to treatment with RRx-001 and whole brain radiotherapy (WBRT) without neurologic or systemic toxicity in the context of a phase I/II clinical trial. RRx-001 is an reactive oxygen and reactive nitrogen species (ROS/RNS)-dependent systemically nontoxic hypoxic cell radiosensitizer with vascular normaliz...

The toxic nerve agent (NA) soman is the most toxic artificially synthesized compound that can rapidly penetrate into the brain and irreversibly inhibit acetylcholinesterase (AChE) activity, leading to immediate death. However, there are currently few brain-targeted nanodrugs that can treat acute chemical brain poisoning owing to the limited drug-releasing speed. The present study investigated t...

We reevaluate the treatment of mercury poisoning, incorporating recent advances in understanding toxicity and mercury:selenium interaction. This review focuses on: 1) role, limitations benefits chelation (Unithiol, succimer N-Acetylcysteine); 2) role selenium supplementation; 3) how different forms are impacted by use selenium. Unithiol produce increases urinary excretion to a lesser degree blo...

Abstract Antibody-based conjugates (ADCs) have transformed the treatment of Her2+ breast and other cancers. Unfortunately, CNS remains a sanctuary site for many such patients in part due to differential activity macromolecules across blood-brain tumor barriers. Trastuzumab deruxtecan (T-DXd), high-payload ADC, was recently found improve progression-free survival cancer compared with prior-gener...
