Cancer and Polymeric-Carriers

Abstract

Advances in medicine and pharmacy have saved many lives from death. Researchers and scientists around the world have made great strides with their findings, not only improving public knowledge with their findings but also keeping hope alive in the hearts of some people with incurable diseases. Various sciences accompanied medicine and pharmacy in this development, one of which is polymer engineering. Polymers due to amazing properties can be used as prostheses, drug carriers, gene delivery, etc. Polymers are unique candidates for the release of anticancer drugs. Non-toxicity, and biodegradability are important features of a carrier. This study summarizes cancer statistics and introduces several polymer-carriers.

Assessment of Some Toxic Metals in Ziziphora (Ziziphora persica) Obtained from Local Market in Lahijan, Northern Iran

“…Due to compounds that do not have metabolization roles in the body, they should be known as something with storage ability in body tissues such as muscles and bones. Toxic metals can cause mental retardation, hearing impairment, immune system dysfunction, brain diseases, blindness, muscle weakness, and cancer (7)(8)(9)(10)(11)(12)(13)(14)(15)(16). The main characteristics of heavy metals are toxic aspects to the living organisms, and even those mentioned as essential can be toxic if present in excess.…”

"A New Perspective on the Introduction of Some Medicinal Plants for Oral Health and Teeth"

“…This substance, which makes up less than 1% of the dry weight of the plant, has medicinal properties that affect living organisms. Medicinal plants contain many ingredients that are used to treat diseases and eliminate its symptoms [1][2][3][4][5][6][7]. Herbal medicine uses plant seeds, roots, leaves, bark or flowers for medicinal purposes.…”

Evaluation of Some Toxic Elements in the Soil of Langerud: SNorthern Iran

“…This is while in Iran and many developing countries, leaded gasoline is used, and it has and will have many consequences for the people of these societies. It should be said that the lead used in paints causes the contamination of toxic elements in the soil of different regions and can enter the body structure of humans through inhalation and oral intake and cause side effects [7,8]. There is no doubt about the toxicity of this element, and unfortunately, during the absorption of Pb and of course its transfer to many parts of the body, it can be in the blood, absorbing tissues such as liver, kidney, lung, brain, spleen, muscle, and heart, and of course some other tissues like the bones and teeth which remain cumulatively stable.…”

“…It can be predicted that consists of 1.5-5x10-4% of the earth's crust. These statistics include sedimentary and igneous rocks, some coal and peat, and large amounts of sediments [14,15]. It is almost clear to everyone that the toxic element is biologically classified as a toxic element and is among the potential threats to the health and stability of human health, and sometimes in case of excessive accumulation in the human body for various reasons, it can cause some cancers such as lung and ovary [16][17][18].…”
