Cancer Diagnostic Probe
The Cancer Diagnostic Probe (CDP) is a medical device used in Iran during breast cancer surgery. First developed by Nano Hesgar Sazan Salamt Arya, an Iranian company, CDP has received medical approval in Iran, where it is used in surgical centers. Development and application The Cancer Diagnostic Probe was developed by a team led by Mohammad Abdolahad, a 2019 Mustafa Prize laureate and faculty member of the School of Electrical and Computer Engineering at the University of Tehran, to facilitate the determination of cancerous margins. Abdolahad stated that the clinical trial for the device lasted 4 years and that up to 500 surgeries had been carried out using the CDP by 2020. According to Sayyed Ruhollah Miri, the head of the Cancer Institute at the Tehran University of Medical Sciences, the CDP reduces the diagnosis time to 1–2 minutes. Mechanism The CDP device is composed of three main parts: "a disposable sensor; a wireless electrical head probe used by the surgeon; nda m ...

Resection Margin
A resection margin or surgical margin is the edge or "margin" of apparently non-tumorous tissue around a tumor that has been surgically removed, called " resected", in surgical oncology. The resection is an attempt to remove a cancer tumor so that no portion of the malignant growth extends past the edges or margin of the removed tumor and surrounding tissue. These are retained after the surgery and examined microscopically by a pathologist to see if the margin is indeed free from tumor cells (called "negative"). If cancerous cells are found at the edges (called "positive") the operation is much less likely to achieve the desired results. The size of the margin is an important issue in areas that are functionally important (i.e., large vessels like the aorta or vital organs) or in areas for which the extent of surgery is minimized due to aesthetic concerns (i.e., melanoma of the face or squamous cell carcinoma of the penis). The desired size of margin around the tumour can vary. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tehran University Of Medical Sciences
Tehran University of Medical Sciences (TUMS) (, ''Danushgah-e 'lum Pezeshki-ye Tehran'') is the largest and most highly ranked medical university of Iran. In September 2008, Iran's Minister of Health, Treatment, and Medical Education, Lankarani, called TUMS a pioneer in research throughout the country with a noticeable lead over its peers. Located in Tehran, adjacent to the main University of Tehran campus, it was founded as part of Dar ol-Fonoon in 1851, and absorbed into the University of Tehran in 1934. It finally separated from University of Tehran by parliamentary legislation in 1986, coming under the new Ministry of Health, Treatment, and Medical Education. TUMS is ranked as one of Iran's top research universities, with an annual research budget of over 300 billion Rials. The school trains over 13,000 students (40% of whom are women) in approximately 290 undergraduate, graduate and non-degree (short-course) programs. The university has 11 schools, operates 16 teaching ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrochemistry
Electrochemistry is the branch of physical chemistry concerned with the relationship between Electric potential, electrical potential difference and identifiable chemical change. These reactions involve Electron, electrons moving via an electronically conducting phase (typically an external electrical circuit, but not necessarily, as in Electroless nickel-phosphorus plating, electroless plating) between electrodes separated by an ionically conducting and electronically insulating electrolyte (or ionic chemical species, species in a Solution (chemistry), solution). When a chemical reaction is driven by an electrical Voltage, potential difference, as in electrolysis, or if a potential difference results from a chemical reaction as in an electric battery or fuel cell, it is called an ''electrochemical'' reaction. Unlike in other chemical reactions, in electrochemical reactions electrons are not transferred directly between atoms, ions, or molecules, but via the aforementioned electron ...

Metabolism
Metabolism (, from ''metabolē'', "change") is the set of life-sustaining chemical reactions in organisms. The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the elimination of metabolic wastes. These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their Structures#Biological, structures, and respond to their environments. The word ''metabolism'' can also refer to the sum of all chemical reactions that occur in living organisms, including digestion and the transportation of substances into and between different cells, in which case the above described set of reactions within the cells is called intermediary (or intermediate) metabolism. Metabolic reactions may be categorized as ''catabolic''—the ''breaking down'' of compounds (for example, of glucose to pyruvate by c ...

Hydrogen Peroxide
Hydrogen peroxide is a chemical compound with the formula . In its pure form, it is a very pale blue liquid that is slightly more viscosity, viscous than Properties of water, water. It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use. Concentrated hydrogen peroxide, or "high-test peroxide", decomposes explosively when heated and has been used as both a monopropellant and an oxidizer in rocketry. Hydrogen peroxide is a reactive oxygen species and the simplest peroxide, a compound having an oxygen–oxygen single bond. It decomposes slowly into water and elemental oxygen when exposed to light, and rapidly in the presence of organic or reactive compounds. It is typically stored with a Stabilizer (chemistry), stabilizer in a weakly acidic solution in an opaque bottle. Hydrogen peroxide is found in biological systems including the human body.

Warburg Effect (oncology)
In oncology, the Warburg effect () is the observation that most cancers use aerobic glycolysis and lactic acid fermentation for energy generation rather than the mechanisms used by non-cancerous cells. This observation was first published by Otto Heinrich Warburg, who was awarded the 1931 Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme". The existence of the Warburg effect has fuelled popular misconceptions that cancer can be treated by dietary reductions in sugar and carbohydrate. In fermentation, the last product of glycolysis, pyruvate, is converted into lactate (lactic acid fermentation) or ethanol ( alcoholic fermentation). While fermentation produces adenosine triphosphate (ATP) only in low yield compared to the citric acid cycle and oxidative phosphorylation of aerobic respiration, it allows proliferating cells to convert nutrients such as glucose and glutamine more efficiently into biomass by avoiding unnecessary ...

Patent Application
A patent application is a request pending at a patent office for the grant of a patent for an invention described in the patent specification and a set of one or more claim (patent), claims stated in a formal document, including necessary official forms and related correspondence. It is the combination of the document and its processing within the administrative and legal framework of the patent office. To obtain the grant of a patent, a person, either legal or natural, must file an application at a patent office with the jurisdiction to grant a patent in the geographic area over which coverage is required. This is often a national patent office, but may be a regional body, such as the European Patent Office. Once the patent specification complies with the laws of the office concerned, a patent may be granted for the invention described and claimed by the specification. The process of "negotiating" or "arguing" with a patent office for the grant of a patent, and interaction with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iranian Inventions
Iran has made considerable advances in science and technology through education in Iran, education and training, despite sanctions against Iran, international sanctions in almost all aspects of research during the past 30 years. Higher education in Iran, Iran's university population swelled from 100,000 in 1979 to 4.7 million in 2016. In recent years, the growth in Iran's scientific output is reported to be the fastest in the world. Science in ancient and Medieval Iran (Persia) Science in Persia evolved in two main phases separated by the arrival and widespread adoption of Islam in the region. References to scientific subjects such as natural science and mathematics occur in books written in the Zoroastrian Middle Persian, Pahlavi languages. Ancient technology in Iran The Qanat (a water management system used for irrigation) originated in pre-Achaemenid Iran. The oldest and largest known qanat is in the Iranian city of Gonabad, which, after 2,700 years, still provides dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
