Appraising Mahallat Geothermal Region using thermal surveying data accompanied by the geological, geochemical and gravity analyses

Mahallat Geothermal Region, located in the central part of Iran, is known as one of the largest lowtemperature geothermal fields. In this study, Mahallat geothermal resource has been evaluated based on integrated geological, geochemical and geophysical analyses. Gravity data revealed three major negative anomaly zones. Based on the geochemical analyses, quartz geothermometers are more reliable than others and confirmed that the reservoir is about 90 °C. Lithological properties of Jurassic layers and high sulphate content observed in geochemical data showed traces of the coalrich layers on the hot fluids. Measured temperatures in 7 boreholes with the depths ranging from 50 to 100 m, have proposed that expected geothermal gradient will be about 81.5 °C/km. Among all drilled boreholes, the data coming from only one resulted in this almost reliable gradient. Other boreholes are clearly too shallow or affected by upflow or downflow of water along existing faults. Geological, geochemical, gravity and measurements of drilled boreholes suggested the existence of a shallow reservoir with an approximate temperature of 90 °C. Regarding gravity and observed faults, geothermal reservoir is elongated parallel to one of the main faults of the region with NE-SW strike

Medical Function of Bacterial Extracellular Vesicles

Extracellular vesicles are nanoscale particles which were identified about fifty years ago. The studies have shown that all of the gram-negative bacteria secrete extracellular vesicles during their normal growth. Today, the production of membrane vesicles has been reported by gram-positive bacteria, parasites, fungi, and mycobacteria. Since these nanoscale particles carry many of the bacterial components such as DNA, RNA, protein, endotoxin, and virulence molecules, they play a very important role in interacting with the environment and other bacteria. For this reason, many of these vesicles are considered as the transmission of pathogens, antigenic protein compounds, and the development of non-cellular vaccines, as well as drug delivery agents. The studies, have been carried in this field so far, have been focused on the pathogenic and physiological roles of these nanostructures in cross-species relationships. The focus of this article is on the role of extracellular bacterial vesicles and pathological and physiological functions which contribute to the interactions between bacteria and bacterium-host. Since these nanostructures play significant role in pathogenesis, gene transduction, regulation of gene expression, immune response regulation, and cellular signaling, further studies are needed on the medical application of these nanostructures as a new generation of vaccines, adjuvants, drug delivery agents

Nano-scaled Diethylene Triamine Pent Acetic Acid (N-DTPA): Novel Anti-Wilson's Disease Cell Model

Abstract Wilson's disease (WD) is an autosomal recessive disorder in which copper metabolism is impaired. In fact, copper accumulates in various organs and tissues can be seen and causes toxic effects in various tissues including liver, brain, kidneys and eyes. Sulfur amino acid is a metabolite of D-penicillamine and penicillamine and copper Chlator is a factor that causes urinary excretion of copper and WD therapeutic agent as well. The interesting thing about the neurological symptoms of Wilson's disease with penicillamine is the drug may worsen or even in an asymptomatic patient, the treatment may be creating symptoms. DTPA is a pentavalent compound containing carboxylic DTPA is a chemical compound that is used in radiation therapy and MRI. It can give the metal chelate with iron, copper and other cations can be conjugated and also treatment of internal body pollution caused by various elements, including raDOIactive elements. DTPA could not be lonely absorbed by the cell. The goal is to conjugate it with the G2 Dendrimer (Nanosized anionic linear biocompatible polymer) to bring it to the nano size and increase the intracellular uptake compared to the ground state. Based on the hypothesis, nanoconjugated DTPA-Dendrimer G2 was synthesized and then evaluated on Hep G2 WD cell model in vitro and the results showed a good effectiveness without any toxicity for the conjugate in decreasing the intracellular copper level comparing to gold standard D-penicillamine respectively. Based on the findings the nanosized conjugate seems to have very good prognoses and clinical future and this needs to be further investigated
