Research ArticleOpen accessIn the keywordsImproving Medical Imaging and Blood Flow Measurement by using a New Doppler Effect RelationshipFlorian Ion T. PetrescuThe Doppler Effect represents the frequency variation of the waves, received by an observer which is drawing (coming), respectively it’s removing (going), from a wave spring (source). One proposes to study the Doppler Effect for the light waves, generally for the electromagnetic waves. Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 14 Oct 2015 · 12,852 accessesView PDF Cite

Research ArticleOpen accessIn the abstractColor Doppler Evaluation of Isovolumetric Relaxation Time and of Signals Arising from Axons of the Median Nerve as a Means to Evaluate Mitochondrial Functionality in the Context of Immunotherapy of Cancer and Chronic Conditions Associated with Mitochondrial DysfunctionStefania Pacini, Marco RuggieroReactive Oxygen Species (ROS) arising from the disruption of mitochondrial respiration act as endogenous mutagens and tumor promoters. When production of ROS exceeds the capacity of DNA repair mechanisms, random mutations and aneuploidy ensue, thousands of genes become unbalanced and genetic/epigenetic chain reactions lead to progressive aneuploidy with only two outcomes: karyotypes so altered that are not viable or karyotypes … …American Journal of Immunology, Vol. 15, Issue 1 · 12 Oct 2019 · 9,690 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNUTRITIONAL CHARACTERISTICS OF THE DAIRY COW DURING EARLY GESTATION AND SUBSEQUENT GROWTH AND CARDIAC MEASUREMENTS OF HER OFFSPRINGJ. E. Larson, B. E. Voelz, D. K. Hardin, C. O. LemleyThe objective was to determine whether maternal nutritional status and milk production during early gestation influenced or were correlated with parameters of the calf at birth and at 1 month of age. From parturition until 90 days pregnant, blood samples were collected every 14 days in dairy cows and plasma was assayed for concentrations of glucose and β-Hydroxybutyrate (BHBA). Calves … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 3 · 15 Sep 2014 · 7,625 accessesView PDF Cite
