Research ArticleOpen accessIn the keywordsComparative Permeation Studies between Scale Region of Shed Snake Skin and Human Skin In vitroAroonsri Priprem, Chidchanok Khamlert, Thaned Pongjanyakul et al.Scales of shed king cobra (Ophiophagus hannah) skin from the dorsal portions, (SSS) and human breast epidermis (HE) were used as barrier membranes for comparison in an in vitro drug permeation study of nine active compounds (MW range 150-300 g mol-1, pKa 3-10). Each compound, saturated in a donor solution at pH 4.0 or 5.6, permeated through the barrier membrane, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,419 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFabrication of a Capacitance-Based Tactile Sensor with Biomedical ApplicationsAli Tavakoli Golpaygani, Siamak Najarian, M. Mehdi Movahedi, Goldis Darb EmamiehThe design, modeling, and testing of a flexible tactile sensor and its applications are presented. This sensor is made of polymer materials and can detect the 2D surface texture image and contact-force estimation. The sensing mechanism is based on the novel contact deflection effect of a membrane. We measure the amount of membrane deflection with measuring the change of capacitance … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 7,394 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPunicalagin Suppresses Mediators Involved in Labor Onset and Progression in vitroCaitlyn Nguyen-Ngo, Jane C Willcox, Martha LappasSpontaneous preterm birth is the leading cause of neonatal morbidity and mortality. Inflammation plays a central role in the activation of myometrial contractions and rupture of fetal membranes associated with spontaneous preterm birth. The pomegranate polyphenol punicalagin is known to possess anti-inflammatory properties. In this study, we aimed to determine the effect of punicalagin on pro-inflammatory and pro-labor mediators in … …American Journal of Immunology, Vol. 17, Issue 1 · 22 Dec 2021 · 7,613 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFour Dimensional (4-D) BioChemInfoPhysics Models of Cardiac Cellular and Sub-Cellular Vibrations (Oscillations)Kang Cheng, Chang-Hua ZouProblem statement: Cardiovascular Diseases (CVD) continued to be the leading cause of death. Failure or abnormal cardiac cellular or sub-cellular vibrations (oscillations) could lead failure or abnormal heart beats that could cause CVD. Understanding the mechanisms of the vibrations (oscillations) could help to prevent or to treat the diseases. Scientists have studied the mechanisms for more than 100 years. To … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 15 Jun 2009 · 7,062 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLaser Therapy of Irradiated Traumatized Skeletal Muscles and State of Immune System in AnimalsNelly Bulyakova, Svetlana Zubkova, Valentina AzarovaProblems statement: This study was designed to examine the effect of laser therapy on regeneration of traumatized skeletal muscles and on dynamics of immune responses in thymus and bone marrow under ionizing radiation. Approach: After local X-ray radiation of both rat gastrocnemius muscles at a dose 20 Gy or after total γ-irradiation of animals at a semiletal dose 6 Gy, … …OnLine Journal of Biological Sciences, Vol. 11, Issue 2 · 27 Aug 2011 · 8,200 accessesView PDFCite
Research ArticleOpen accessIn the keywordsKinetic Optimization of Folic Acid Polymer Conjugates for Drug TargetingJacob M. Ngoy, Sunny E. Iyuke, Clarence S. Yah, Wilhelm E. NeuseProblem statement: Folic Acid (FA) is an essential, bioavailable water soluble B-complex vitamin that helps in the replication of normal cells. It is obtained from natural sources and it deficiency can leads to oncogenic cells development. Within this frame work in mind, we designed and synthesized a new bioconjugate carrier that can enhance the effectiveness of FA. Approach: The polymeric … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 7,110 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSynthesis of Mesoporous Titania with Surfactant and its CharacterizationT. Benkacem, N. AgoudjilA mesoporous titania was obtained by gelation from Ti-alkoxide in acidic solutions with addition of surfactant cetyltrimetylammonium bromide (CH3(CH2)15N(CH3)3Br) using a sol-gel process. The effects of surfactant concentration on synthesis of mesoporous titania were studied. The structural characterisation was studied by differential thermal analysis, infrared spectroscopy, X-ray diffraction. Studies by X-ray diffraction showed that crystallisation of TiO2 powder occurs at … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,418 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIsolation and Identification of Listeria monocytogenes in Processed Meat by a Combined Cultural-molecular MethodAngela Ingianni, Marta Quartuccio, Maria Antonietta Madeddu et al.The isolation and identification of Listeria monocytogenes in processed meat samples by a combined cultural-molecular method is described. It allows the identification of Listeria strains by means of a hybridization technique with a specific DNA probe directed to the listerial internalin gene. The specificity of this method was found to be 100% and sensitivity was as low as 1 CFU/2.5 … …American Journal of Infectious Diseases, Vol. 3, Issue 3 · 30 Sep 2007 · 7,256 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Integrated Nursing and Digital Droplet PCR on Bullous Dermatoid Conditions: A Randomized Controlled TrialConghui ChenBullous skin disease is an autoimmune disease characterized by the formation of blisters on the skin or mucous membrane, which seriously impairs the quality of life and overall health. Similar to the research on biomolecules (mechanics of protein interaction), cells (including cell membrane elasticity, cell adhesion, cytoskeletal dynamics, response to mechanical stimulation, cell deformation and cell endoforce transfer) and tissue … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 2 Jul 2026 · 993 accessesView PDFCite
