In mid-October, for three weeks the American economy suffered as the New York Stock Exchange dropped 50% during the first week. At the time the U.S. populace was much smaller than it is today with only around 87 million citizens. The panic that ensued caused many runs on banks, savings and loan firms, and trust companies.
Depositors panicked because bankers were caught red-handed setting up ‘bucket shops’ with people’s deposits and only keeping a fraction of reserves on hand. This ultimately led to the fall of the Knickerbocker Trust and this is why some people call the panic of 1907 the ‘Knickerbocker Crisis.’
Scholarly articles show that one man, JP Morgan, and his crew of New York bankers saved the day. Even though Morgan and his cronies were responsible for the side bets, he and his crew also stepped in to offer a solution...
A nanoparticle or ultrafine particle is usually defined as a particle of matter that is ... of nanoprisms give rise to high effective cross- sections and deeper colors of the colloidal solutions.
A very popular antigen carrier used for immunization and vaccination is gold nanoparticles (GNPs) [68–71]. Owing to their unique physicochemical properties, ease of preparation, and low toxicity, GNPs are widely used in various fields of biomedical research [72].16 Apr 2020

An RNA vaccine or mRNA (messenger RNA) vaccine is a type of vaccine that uses a copy of a natural chemical called messenger RNA (mRNA) to produce an immune response.

The inflammatory response (inflammation) occurs when tissues are injured by bacteria, trauma, toxins, heat, or any other cause. The damaged cells release chemicals including histamine, bradykinin, and prostaglandins. These chemicals cause blood vessels to leak fluid into the tissues, causing swelling.
RNA viruses can be further classified according to the sense or polarity of their RNA into negative-sense and positive-sense, or ambisense RNA viruses...
RNA viruses generally have very high mutation rates compared to DNA viruses, because viral RNA polymerases lack the proofreading ability of DNA polymerases. The genetic diversity of RNA viruses is one reason why it is difficult to make effective vaccines against them.
Numerous RNA viruses are capable of genetic recombination when at least two viral genomes are present in the same host cell. RNA recombination appears to be a major driving force in determining genome architecture and the course of viral evolution among Picornaviridae ((+)ssRNA) (e.g. poliovirus). In the Retroviridae ((+)ssRNA)(e.g. HIV), damage in the RNA genome appears to be avoided during reverse transcription by strand switching, a form of recombination.
Recombination also occurs in the Reoviridae (dsRNA)(e.g. reovirus), Orthomyxoviridae ((-)ssRNA)(e.g. influenza virus) and Coronaviridae ((+)ssRNA) (e.g. SARS). Recombination in RNA viruses appears to be an adaptation for coping with genome damage. Recombination can occur infrequently between animal viruses of the same species but of divergent lineages. The resulting recombinant viruses may sometimes cause an outbreak of infection in humans.
The names assigned to each strand actually depend on which direction you are writing the sequence that contains the information for proteins (the "sense" information), not on which strand is depicted as "on the top" or "on the bottom" (which is arbitrary). The only biological information that is important for labeling strands is the relative locations of the terminal 5′ phosphate group and the terminal 3′ hydroxyl group (at the ends of the strand or sequence in question), because these ends determine the direction of transcription and translation.

by S Arunragsa · 2020 · Cited by 9 — In this work, an alternative room-temperature gas sensor was fabricated by drop-casting hydroxyl-functionalized graphene quantum dots (OH-GQDs) onto an interdigitated nickel electrode. The OH-GQDs were prepared based on a bottom-up approach using the hydrothermal treatment of pyrene.
Ultrasmall black phosphorus quantum dots: synthesis, characterization, and application in cancer treatment - Analyst (RSC Publishing)
Black phosphorus quantum dots (BPQDs) are gaining popularity for applications in various fields because of their unique advantages. For biomedical applications, good biosafety is a prerequisite for the use of BPQDs in vivo. However, currently, little information is available about their basic proper..
