Hamid Tebyanian Ali Karami Ebrahim Motavallian Jafar Aslani Alí Samadikuchaksaraei

BACKGROUND: Lung disease is the most common cause of death in the world. The last stage of pulmonary diseases is lung transplantation. Limitation and shortage of donor organs cause to appear tissue engineering field. Decellularization is a hope for producing intact ECM in the development of engineered organs.AIM: The goal of the decellularization process is to remove cellular and nuclear material while retaining lung three-dimensional and molecular proteins. Different concentration of detergents was used for finding the best approach in lung decellularization.MATERIAL AND METHODS: In this study, three-time approaches (24, 48 and 96 h) with four detergents (CHAPS, SDS, SDC and Triton X-100) were used for decellularizing rat lungs for maintaining of three-dimensional lung architecture and ECM protein composition which have significant roles in differentiation and migration of stem cells This comparative study determined that variable decellularization approaches can cause significantly different effects on decellularized lungs.RESULTS: Results showed that destruction was increased with increasing the detergent concentration. Single detergent showed a significant reduction in maintaining of three-dimensional of lung and ECM proteins (Collagen and Elastin). But, the best methods were mixed detergents of SDC and CHAPS in low concentration in 48 and 96 h decellularization.CONCLUSION: Decellularized lung tissue can be used in the laboratory to study various aspects of pulmonary biology and physiology and also, these results can be used in the continued improvement of engineered lung tissue.

DEGRADATION OF ALKANES IN CONTAMINATED SITES

International Journal of Advanced Biological and Biomedical Research (2014)

Aliakbari Ehsan Hamid Tebyanian Mehdi Hassanshahian Kariminik Ashraf

Petroleum hydrocarbons are important energy resources used by industry and in our daily life, whose production contributes highly to environmental pollution. To control such risk, bioremediation constitutes an environmentally friendly alternative technology that has been established and applied. It constitutes the primary mechanism for the elimination of hydrocarbons from contaminated sites by natural existing populations of microorganisms. Petroleum (or crude oil) is a complex mixture of hydrocarbons. Annually, millions of tons of crude petroleum oil enter the marine environment from either natural or anthropogenic sources. Hydrocarbon-degrading bacteria (HDB) are able to assimilate and metabolize hydrocarbons present in petroleum. Crude oil pollution constitutes a temporary condition of carbon excess coupled to a limited availability of nitrogen that prompts marine oil-degrading bacteria to accumulate storage compounds. This review focuses on the role and distribution in the environment of degradation bacteria and their (potential) applications in bioremediation and biocatalysis. Bacteria play an important role in the microbial degradation of oil, chlorinated hydrocarbons, fuel additives, and many other compounds. Environmental studies demonstrate the abundance of alkane degraders and have lead to the identification of many new species, including some that are (near) obligate alkanotrophs. Bioremediation is being increasingly seen as an affective, environmentally friendly treatment for contaminated shorelines from marine oil spills. Oil bioremediation is limited by the availability of nitrogen and phosphorous which are needed by the bacteria and are not present in sufficient amounts for the biodegradation of the spilled hydrocarbons.

The Current Strategies in Controlling Oral Diseases by Herbal and Chemical Materials

Evidence-based Complementary and Alternative Medicine (2021)

Mohammad Nima Motallaei Mohsen Yazdanian Hamid Tebyanian Elahe Tahmasebi Mostafa Alam

Dental plaque is a biofilm composed of complex microbial communities. It is the main cause of major dental diseases such as caries and periodontal diseases. In a healthy state, there is a delicate balance between the dental biofilm and host tissues. Nevertheless, due to the oral cavity changes, this biofilm can become pathogenic. The pathogenic biofilm shifts the balance from demineralization-remineralization to demineralization and results in dental caries. Dentists should consider caries as a result of biological processes of dental plaque and seek treatments for the etiologic factors, not merely look for the treatment of the outcome caused by biofilm, i.e., dental caries. Caries prevention strategies can be classified into three groups based on the role and responsibility of the individuals doing them: (1) community-based strategy, (2) dental professionals-based strategy, and (3) individual-based strategy. The community-based methods include fluoridation of water, salt, and milk. The dental professionals-based methods include professional tooth cleaning and use of varnish, fluoride gel and foam, fissure sealant, and antimicrobial agents. The individual-based (self-care) methods include the use of fluoride toothpaste, fluoride supplements, fluoride mouthwashes, fluoride gels, chlorhexidine gels and mouthwashes, slow-release fluoride devices, oral hygiene, diet control, and noncariogenic sweeteners such as xylitol. This study aimed to study the research in the recent five years (2015-2020) to identify the characteristics of dental biofilm and its role in dental caries and explore the employed approaches to prevent the related infections.

Ultrasound irradiation and green synthesized CuO-NiO-ZnO mixed metal oxide: An efficient sono/nano-catalytic system toward a regioselective synthesis of 1-aryl-5-amino-1H-tetrazoles

Synthetic Communications (2020)

Monireh Atarod Javad Safari Hamid Tebyanian

An efficient approach has been reported that 1-aryl-5-amino-1H-tetrazoles are prepared from structurally diverse N-arylcyanamides and sodium azide using sono/nano-catalytic system. The mixed metal oxide nanoparticles (NPs) (CuO, NiO, and ZnO NPs) were prepared with utilizing aqueous leaves extracts of the Rheum ribes. In this study, the effect of the reaction condition was investigated on the catalytic activity and selectivity of mixed metal oxide NPs for the synthesis of aminotetrazole derivatives. In this regard, various reaction conditions were precisely compared such as reflux and ultrasonication (US). In this study, the regioselective synthesis of 1-aryl-5-amino-1H-tetrazoles with high yield was achieved by the synergistic effect between US irradiation and prepared nanocatalyst which showed the potential of sono/nano-catalytic system in organic synthesis. Furthermore, the as-prepared nanocatalyst could be reused and recovered from the reaction mixture for several times without consequential abate in its catalytic activity and selectivity.

Today, the use of pesticides is an essential issue for health control. Organophosphorus insecticides are considered as the most widely used pesticides in the world and as they have the potential to eliminate pests, they can endanger human health by inhibiting acetylcholinesterase family enzymes. In this research, we aimed to study the effects of paraxon, most important metabolite of organophosphorus insecticide partion, on the viability, cytotoxicity, and apoptosis occurrence in the presence of butyrylcholinesterase (BCHE). In this study, the effects of the viability, cytotoxicity, and apoptosis of paraxon-induced PC12 cells were investigated in the presence of butyrylcholinesterase (BCHE). The cell viability was assessed using MTT test. The cell cytotoxicity was calculated through Lactate Dehydrogenase (LDH) test. The caspase activity was used to measurement of caspase-3 activity. Mitochondrial membrane potential (MMP) was studied by rhodamine123 and also, TUNEL staining was performed to quantification of apoptosis index. Paraxon induced cell cytotoxicity and decrease cell viability of PC12 cells and BCHE inhibited the paraxon function in a dose-dependent manner. Paraxon disrupted the MMP and increased the function of caspase but BCHE suppressed paraxon-induced apoptosis through inhibition of paraxon function. Treatment of PC12 cell by paraxon increased cell death index. BCHE can use in treatment of poisoning with organophosphorus insecticides because of its potential to suppress the paraxon-induced cell death. BCHE inhibits the paraxon function in a dose-dependent manner.

Farzaneh Golfeshan Allahyar Noori Ali Karami Aref Barkhordari Lila Kiani

Carbon nanotube (CNT) can be considered as one of the best materials for enzyme nanobiosensor. In this study, we investigated comprehensively electron transfer properties in three kinds of carbon nanotubes for finding the best supporting material for comprising of the electrochemistry and electrocatalysis of enzymes in nano-dimension. Choline oxidase was selected as a sample enzyme for evaluating the performance of the electrodes. The enzyme was absorbed on modified SWCNT, MWCNT and Bamboo-like CNTs electrode in ionic liquid. Electron transfer and electroanalytical responses were investigated by Metrohm Autolab. Functionalization was studied by Raman spectroscopy and FTIR and also, the morphological evaluation was conducted by SEM. Raman spectroscopy showed that Bamboo-like CNTs had better properties in loading enzyme and other electrochemical properties for electron transfer. FTIR spectroscopy showed that Bamboo-like CNTs had high covalent binding on the surface wall of nanotubes. High loading of the enzyme was detected in Bamboo-like CNTs in comparison to two other nano-tubes by SEM. The electrochemical and amperometric response showed that Bamboo-like CNTs had a better response in different scan rates, wide linear range and detection limit. ChOx/RTIL/Bamboo-like CNTs/GC electrodes showed the high amounts of enzyme loading, high enzyme-substrate affinity, low detection limit, best sensitivity and wider linear range.

Hexadecane-degradation by Teskumurella and Stenotrophomonas Strains Isolated From Hydrocarbon Contaminated Soils

Jundishapur Journal of Microbiology (2013)

Hamid Tebyanian Mehdi Hassanshahian Ashraf Kariminik

Background: Petroleum hydrocarbons are mix compounds and divided into four groups: Saturates, Aromatics, Resins and Asphalten. Among various phases of crude-oil, the alkanes with medium length chain are favorable substrates that rapidly degraded, although short-chain alkanes are very toxic and long-chain alkanes have low solubility in water that reduce its bioavailability and make resistant to biodegradation. Objectives: The main goal of this study is the isolation, molecular identification and degradation properties of hexadecane degrading bacteria from contaminated soils. Materials and Methods: In this research to isolate aliphatic degrading bacteria, sampling from hydrocarbon contaminated soil with of petroleum reservoirs regions, Tehran were performed. Alkane degrading bacteria were isolated by enrichment in Bushnel-Hass medium with hexadecane as sole source of carbon and energy. The isolated strains were identified by amplification of 16S rDNA gene and sequencing. Alkane hydroxylase gene (alk-B) was identified in all strains by PCR with specific primers. Results: Among 8 strains three strains with high growth rate on hexadecane selected for further study. These three selected strains identified as Stenotrophomonas maltophilia strain M2, S. maltophilia strain Q2 and Tsukamurella tyrosinosolvens strain Q3. In comparison to the other bacteria, these bacterial strains can degrade hexadecane 2 times more; with a high emulsification activity. Conclusions: The 2.5% concentration of hexadecane was the best concentration that supports the growth of these strains. Among these strain T. tyrosinosolvens strain Q3 was the best strain for biodegradation of hexadecane. Alk-B gene was identified in all strains.

Histologic analyses of different concentrations of TritonX-100 and Sodium dodecyl sulfate detergent in lung decellularization

Cellular and Molecular Biology (2017)

Hamid Tebyanian Ali Karami Ebrahim Motavallian J Aslani Alí Samadikuchaksaraei

Pulmonary diseases cusecs a large portion of mortality in the world. There is no more cure for pulmonary diseases and many approaches are needed for finding ways to cure. Nowadays, implantation and drugs are only ways for curing those people who are facing with these diseases. Tissue engineering and regenerative medicine have been appeared as multidisciplinary field and also, they presents new therapeutic approaches for pulmonary diseases. One of these therapeutic approaches is decellularization which removes cellular but leaves intact important extracellular matrix (ECM) proteins and three-dimensional (3D) architecture and also, this approach has been studied for in-vitro and ex-vivo. In this study, we aimed to investigate a comparison of different concentrations of Triton X-100 and Sodium dodecyl sulfate detergents in lung decellularization in order to evaluate the effects of different concentrations and times of mentioned detergents on three dimensional and ECM proteins lung. Two detergents (Triton-X100 and Sodium dodecyl sulfat) were used with different concentrations for decellularizing rat lungs for maintaining of three-dimensional lung architecture and ECM protein compositions which have significant roles in differentiation and migration of stem cells. Results showed that SDS 0.05%, 0.1% and Triton-X100 0.1% could maintain 3D, elastin and collagen better than other concentrations in 24 and 48 h- decellularization. We concluded that these approaches can help to achieve three-dimensional architecture and extracellular matrix of lung with minimum destruction for next step such as recellularization and in-vivo study.

Iranian journal of pathology (2022)

Seyed-Hashem Daryabari Hossein Aghamollaei Fahimeh Asadi Amoli Khosrow Jadidi Hamid Tebyanian

Background & Objective: Delayed mustard gas keratopathy (DMGK) is the main chronic outcome in eye-chemical injured patients. The aim of this study was the histopathological evaluation of mustard-exposed cornea after more than 30 years.Methods: Fourteen corneas after Lamellar keratoplasty were evaluated in this study. Corneal tissues were prepared by histologic methods and stained by H&E.Results: The main histopathological findings in these cases were the presence of severe stromal edema and corneal scar. In the sections with visible superficial epithelium, subepithelial bullae formation was observed. Focal or diffuse disruption of Bowman's membrane and replacement with fibrosis were also seen. There was no evidence of stromal vascularization and inflammation in all specimens.Conclusion: After more than 30 years, an extensive corneal scar is seen in sulfur mustard exposed patients. Scar tissue without vascularization and fibroblastic proliferation is the main finding in the sulfur mustard exposed cornea. This pathology result is different from other scars. No evidence of inflammation or immune cell infiltration should be considered in managing DMGK.

The Effects of some Physicochemical Stresses on Escherichia coli O157:H7 as Clinical Pathogenic Bacteria

International Journal of Agriculture and Biology (2016)

Hamidreza Yazdi Ali Karami Hamid Babavalian Seyed Ali Mirhosseini Hamid Tebyanian

Escherichia coli O157:H7 is a member of Enterobacteriaceae cocobacilla, which is gram negative and it causes gastrointestinal disease such as Diarrhea, Hemorrhagic colitis, and Hemolytic uremic.The first aim of this study was to examine E. coli O157:H7 in planktonic and biofilm state under stressed conditions of NaCl, pH, temperature and ORS (Oral Rehydration Salt) powder and then make comparisons.The second aim was to examine the shape of the bacterium in microscopic (bacteria shape) and macroscopic (bacterial colonies in Nutrient Agar culture media).Bacterial strains of E. coli O157:H7 were purchased (No. (NCTC) 12900).The bacteria were placed in liquid Nutrient Broth culture media and then transferred to Nutrient Agar culture media into plates to examine colonial shape.Microtitration plate was used in order to determine the biofilm formation under stressed conditions.Under these conditions, colonial morphology and bacterial shapes were significantly changed and their shapes tended to Cocci and Bacilli in order to survive more.Bacteria survival under stressed conditions was more in biofilm state rather than in Plankton state.This research demonstrated that E. coli O157:H7 had a different kind of effects in physicochemical stresses, while the optimal conditions were found in NaCl, pH, Tm and ORS stresses.
