Ruth Ella Moore
Ruth Ella Moore (May 19, 1903 – July 19, 1994) was an American bacteriologist and microbiologist, who, in 1933, became the first African-American woman to be awarded a Ph.D. in a natural science. She was a professor of bacteriology at Howard University. A decade later, she was installed as the head of the department of bacteriology, which she renamed to the department of microbiology. During that period she was promoted to associate professor of microbiology. She published her research on tuberculosis, immunology, dental caries, the response of gut microorganisms to antibiotics, and the blood types of African-Americans. Although there are gaps in the official personnel records of the university, Moore is believed to have continued to teach and conduct her research at Howard until 1973, after which she held the position of associate professor emeritus of microbiology until 1990. Moore also gained recognition as a fashion designer. Early life and education Ruth Ella Moore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbus, Ohio
Columbus () is the state capital and the most populous city in the U.S. state of Ohio. With a 2020 census population of 905,748, it is the 14th-most populous city in the U.S., the second-most populous city in the Midwest, after Chicago, and the third-most populous state capital. Columbus is the county seat of Franklin County; it also extends into Delaware and Fairfield counties. It is the core city of the Columbus metropolitan area, which encompasses 10 counties in central Ohio. The metropolitan area had a population of 2,138,926 in 2020, making it the largest entirely in Ohio and 32nd-largest in the U.S. Columbus originated as numerous Native American settlements on the banks of the Scioto River. Franklinton, now a city neighborhood, was the first European settlement, laid out in 1797. The city was founded in 1812 at the confluence of the Scioto and Olentangy rivers, and laid out to become the state capital. The city was named for Italian explorer Christopher Columbus. ...

Blood Types
Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells. Blood in the circulatory system is also known as ''peripheral blood'', and the blood cells it carries, ''peripheral blood cells''. Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets (also called thrombocytes). The most abundant cells in vertebrate blood a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gettysburg College
Gettysburg College is a private liberal arts college in Gettysburg, Pennsylvania. Founded in 1832, the campus is adjacent to the Gettysburg Battlefield. Gettysburg College has about 2,600 students, with roughly equal numbers of men and women. Gettysburg students come from 41 states, Washington, D.C., and 39 countries. The school hosts 24 NCAA Division III men's and women's teams, known as the Bullets, and many club, intramural, and recreational programs. The college is also the home of ''The Gettysburg Review'', a literary magazine. History Founding and early roots Gettysburg College was founded in 1832, as a sister institution for the Lutheran Theological Seminary. Both owe their inception to Thaddeus Stevens, a Radical Republican and abolitionist from Gettysburg. The college's original name was Pennsylvania College; it was founded by Samuel Simon Schmucker. In 1839, seven years after Gettysburg College was first founded, Drs. George McClellan (founder of Jefferson Medic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Disk Diffusion Test
The disk diffusion test (also known as the agar diffusion test, Kirby–Bauer test, disc-diffusion antibiotic susceptibility test, disc-diffusion antibiotic sensitivity test and KB test) is a culture-based microbiology assay used in diagnostic and drug discovery laboratories. In diagnostic labs, the assay is used to determine the susceptibility of bacteria isolated from a patient's infection to clinically approved antibiotics. This allows physicians to prescribe the most appropriate antibiotic treatment. In drug discovery labs, especially bioprospecting labs, the assay is used to screen biological material (e.g. plant extracts, bacterial fermentation broths) and drug candidates for antibacterial activity. When bioprospecting, the assay can be performed with paired strains of bacteria to achieve dereplication and provisionally identify antibacterial mechanism of action. In diagnostic laboratories, the test is performed by inoculating the surface of an agar plate with bacte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Griffith's Experiment
Griffith's experiment, reported in 1928 by Frederick Griffith, was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation. Griffith's findings were followed by research in the late 1930s and early 40s that isolated DNA as the material that communicated this genetic information. Pneumonia was a serious cause of death in the wake of the post-WWI Spanish influenza pandemic, and Griffith was studying the possibility of creating a vaccine. Griffith used two strains of pneumococcus ('' Diplococcus pneumoniae'') bacteria which infect mice – a type III-S (smooth) which was virulent, and a type II-R (rough) strain which was nonvirulent. The III-S strain synthesized a polysaccharide capsule that protected itself from the host's immune system, resulting in the death of the host, while the II-R strain did not have that protective capsule and was defeated by the host's immune system. A German bacteriologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schick Test
The Schick test, developed in 1913, is a skin test used to determine whether or not a person is susceptible to diphtheria. It was named after its inventor, Béla Schick (1877–1967), a Hungarian-born American pediatrician. Procedure The test is a simple procedure. A small amount (0.1 ml) of diluted (1/50 MLD) diphtheria toxin is injected intradermally into one arm of the person and a heat inactivated toxin on the other as a control. If a person does not have enough antibodies to fight it off, the skin around the injection will become red and swollen, indicating a positive result. This swelling disappears after a few days. If the person has an immunity, then little or no swelling and redness will occur, indicating a negative result. Results can be interpreted as:Preventive and Social Medicine, Park 22nd edition, pg 151 # Positive: when the test results in a wheal of 5–10 mm diameter, reaching its peak in 4–7 days. The control arm shows no reaction. This indicates tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Physical Anthropology
Biological anthropology, also known as physical anthropology, is a scientific discipline concerned with the biological and behavioral aspects of human beings, their extinct Hominini, hominin ancestors, and related non-human primates, particularly from an evolutionary perspective. This subfield of anthropology systematically studies Homo sapiens, human beings from a biological perspective. Branches As a subfield of anthropology, biological anthropology itself is further divided into several branches. All branches are united in their common orientation and/or application of evolutionary theory to understanding human biology and behavior. * Bioarchaeology is the study of past human cultures through examination of human remains recovered in an archaeology, archaeological context. The examined human remains usually are limited to bones but may include preserved soft tissue. Researchers in bioarchaeology combine the skill sets of human osteology, paleopathology, and archaeology, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
