Use of cold atmospheric plasma in the treatment of cancer
Abstract
Cold atmospheric plasma (CAP) is an emerging modality for the treatment of solid tumors. In-vitro experiments have demonstrated that with increasing doses of plasma, tumor cells assays display decreased cell viability. CAP is theorized to induce tumor cells into apoptosis via multiple pathways including reactive oxygen and nitrogen species as well as cell cycle disruption. Studies have shown CAP treatment can decrease mouse model glioblastoma multiforme tumor volume by 56%, increase life span by 60%, and maintain up to 85% viability of normal cells. Emerging evidence suggests that CAP is a viable in-vivo treatment for a number of tumors, including glioblastoma, as it appears to selectively induce tumor cell death while noncancerous cells remain viable.

Apoptosis in Cancer
Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
Apoptosis
Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
Acute viral rhinopharyngitis
Acute viral rhinopharyngitis, also known as "common cold", is an acute, self-limiting viral infection of the upper respiratory tract involving the nose, sinuses, pharynx and larynx. Discover the latest research on acute viral rhinopharyngitis here.
