Method to Generate Electric Power and Hydrogen in the Absence Of External Energy

Sep 2018 DOI 10.14302/issn.2377-2549.jndc-18-2224
Katsutoshi OnoCorresponding author

This paper describes the theoretical foundations for the electric power and hydrogen generator that functions with zero energy input without violating the laws of thermodynamics. This generation system is a combined energy cycle consisting of the H2O=H2+1/2O2 reduction reaction performed by the wate…

Literature Review Paper on Mechanical Properties of Types of Carbon Nanotubes

Aug 2018 DOI 10.14302/issn.2377-2549.jndc-18-2187
Elias RandjbaranCorresponding author

Among the numerous potential uses of carbon nanotubes (CNT), its utilization to fortify polymers was given careful consideration. This reason can be because of the remarkable firmness, magnificent quality, and the low thickness of CNT. This has given various chances to the innovation of new material…

Additive Manufacturing as A New Technique of Fabrication

Jul 2018 DOI 10.14302/issn.2831-8846.j3dpa-18-2207
Amir DehghanghadikolaeiCorresponding author

Additive manufacturing (AM) is reshaping fabrication in engineering and clinical settings. This editorial highlights metal AM routes—SLS, SLM, DMLS, and EBM—and their application to patient-specific NiTi implants, where biocompatibility and shape-memory behavior are compelling. We note the current g…

Chitin and Chitinases: Biomedical And Environmental Applications of Chitin and its Derivatives

May 2018 DOI 10.14302/issn.2690-4829.jen-18-2043
Palanivel RameshthangamCorresponding author

Disposal of chitin wastes from crustacean shell can cause environmental and health hazards. Chitin is a well known abundant natural polymer extracted after deproteinization and demineralization of the shell wastes of shrimp, crab, lobster, and krill. Extraction of chitin and its derivatives from was…

Hepatic Tuberculosis of Pseudotumor Form

Mar 2018 DOI 10.14302/issn.2578-2371.jslr-18-1994
Meriam SabbahCorresponding author Department of gastroenterology, Habib Thameur Hospital, Tunis, Tunisia.

Tuberculosis involving the liver in the absence of active pulmonary tuberculosis is very rare. The inflammatory pseudotumoral form is an entity difficult to diagnose. We report a case of an inflammatory pseudotumor of the liver due to tuberculosis, who didn’t underwent hepatectomy because of the siz…

Study of VCAM-1 Gene Expression in Normal and Tumoral Tissues in Patients with Colorectal Cancer

Nov 2017 DOI 10.14302/issn.2576-6694.jbbs-17-1744
Frouzandeh MahjoubiCorresponding author

Aim: Colorectal cancer is one of the most commonly diagnosed cancers in the world. Cell adhesion molecules play an important role in the progression of various cancers. It has been shown that the high level expression of some Cell adhesion molecule could be a new diagnostic factor for several cancer…

Template Independent Synthesis of Nucleic Acid Libraries

Sep 2017 DOI 10.14302/issn.2575-7881.jdrr-17-1749
Kiran D. BhilareCorresponding author

Though, directed evolution/In vitro evolution has greatly enhanced the applicability of natural biomolecules, there is still a big void in synthetic biology, which could be filled only when we are able to make novel/synthetic functional biomolecules. Terminal deoxyribonucleotidyl transferase (TdT) i…

Role of Helicobacter Pylori in Nasal Polyp Formation: A Case-Control Study in Tehran, Iran

Jan 2016 DOI 10.14302/issn.2379-8572.joa-15-814
Mohammad FarhadiCorresponding author

Background and Objective: The etiological factors for nasal polyps include infection, inflammation or an imbalance of a metabolic pathway. This study was designed to compare serum Helicobacter pyloriantibodies and H. pylori–DNAs between cases of nasal polyp and controls (nasal fracture). Patients an…

Effect of Nonionic Surfactants and HPMC F4M on the Development of Formulations of Neuro-EPO as a Neuroprotective Agent

Feb 2014 DOI 10.14302/issn.2328-0182.japst-13-206
J. C. García-RodríguezCorresponding author

The purpose of this study was to investigate the effect of cremophor RH-40 and polysorbate 80 with hydroxypropyl methylcellulose (HPMC) F4M on the development of formulations of intranasal erythropoietin with low sialic acid content (Neuro-EPO) as a neuroprotective agent. Parameters such as pH, osmo…
