Biochemistry for Medics – Lecture Notes Hemoglobin, a chromo protein, found exclusively in red blood cells is actually a conjugated protein containing heme as prosthetic group and globin as the protein part apoprotein. The normal concentration of Hb in an adult varies from 14.0 to 16.0 gm%. Approximately 90 mg/kg of Hb is produced and destroyed in the body every day. Hb has a molecular weight of about 67,000. Lead to Gold, Sorcery to Science: Alchemy and the Foundations of Modern Chemistry Mention the word ‘alchemy’ and certain images spring to mind: the lone sorcerer-scholar poring over ancient manuscripts and combining bubbling flasks by flickering candlelight. The associations to the ancient world, at least, are accurate; alchemy’s roots lie in Alexandria, the heart of Hellenistic Egypt, and its intellectual foundation was in Aristotelian philosophy. Arabic scholars brought alchemy into medieval Europe, where it became part of the scholastic academic mainstream of the time.
Renaissance Alchemy and the Scientific Method Few scientific disciplines defined the complexity of the Renaissance as much as alchemy, an area where philosophy, science, occultism and theology came together. Alchemy, a genuine protoscience?, displayed the transformation from theoretical dogma to the observation and practice based methods that gradually developed during this period of the history of science. Fabien Cousteau Leads "Aquanauts" in Record-Breaking Undersea Expedition Fabien Cousteau is leading a team of scientists, educators, and filmmakers this month on the longest-ever expedition in a stationary habitat beneath the sea. The project, called Mission 31, aims to build awareness about the need to protect the ocean and honors a historic expedition 50 years ago by Cousteau's famous grandfather, explorer Jacques Cousteau. Launched on June 1, Mission 31 is a 31-day, privately funded expedition at Florida International University's Medina Aquarius Reef Base.
Mariette DiChristina: "Science Is an Engine of Human Prosperity" On Thursday, July 17, four science experts served as witnesses at the U.S. Senate Committee on Commerce, Science, and Transportation hearing, “The Federal Research Portfolio: Capitalizing on Investments in R&D.” The hearing considered the federal government’s role in research and development (R&D), and the nation’s STEM education and outreach initiatives. Attendees in the Capitol hearing room were Mariette DiChristina, editor in chief and senior vice president of Scientific American; Vinton G.
Imagine If Every School Played *This* Video Before Class Wisdom comes with age, huh? Don't try telling that to Kid President. The kid's on fire in this insightful and funny pep talk that we can all most definitely take something from. Kid President doesn't claim to know it all, but he does know a few things. Cool Videos: Diving for Drugs Who says biomedical scientists always have to work indoors? The next installment in our mini-film fest proves otherwise, offering a close-up look at some medicinal chemists who are busy carrying out their research in warm waters off the Florida Keys. This aquatic adventure may not be as action-packed as “Pirates of the Caribbean” or “Finding Nemo.” But these researchers from the University of Florida College of Pharmacy in Gainesville are out to discover something far more valuable to patients than sunken treasure: marine life with chemical compounds that may provide the basis for new treatments and cures. Here’s their quick summary of their work: “University of Florida College of Pharmacy Researcher and Center for Natural Products, Drug Discovery, and Development Director Hendrik Luesch, Ph.D., collects and studies marine organisms from oceans in Florida and around the globe that have potential for development into drug therapies and disease prevention.”
The Diversity of Coolia spp. (Dinophyceae Ostreopsidaceae) in the Central Great Barrier Reef Region Background Dinoflagellates are important primary producers, crucial in marine food webs. Toxic strains, however, are the main causative agents of non-bacterial seafood poisoning, a major concern for public health worldwide. Despite their importance, taxonomic uncertainty within many genera of dinoflagellates is still high. The genus Coolia includes potentially harmful species and the diversity within the genus is just starting to become apparent. Methodology/Principal Findings
