Here are some pictures that I’ve taken from my past laboratory experiments during the whole foundation year + my first year of BSc (Hons) Biotechnology in university! Had some pictures that are from failed / unsuccessful experiments (ㆀ˘・з・˘)
electron transport chain / oxidative phosphorylation
Designed + drew this electron transport chain(ETC)/oxidative phosphorylation diagram for my Microbiology assignment! The criteria was to draw a diagram based on one of the topics given regarding microbial metabolism + explain it to children in a primary school. It was quite fun to brainstorm ideas for the design + it took me 3 days to complete it. I tried to use food as my theme b/c no kids can resist sweets + snacks right? Hahahah
I had replaced:
- Protein complexes I, III + IVasboba teas/bubble teas
- Protein complex II as a cake
- Cytochrome c as a cake as well
- ATP synthase as a combination of two cakes linked together by a biscuit stick
- Hydrogen ions as the golden (honey) bobas
- Hydrophilic head of phospholipid bilayer as hard-boiled eggs
- Hydrophobic tails of phospholipid bilayer as fries
PS: I used some pictures from laoren-chen and a few textbooks as references! So, credits to them :)
Researchers at the University of British Columbia (UBC), Canada have conducted the world’s first molecular-level structural analysis of the SARS-CoV-2 Omicron variant spike (S) protein. The analysis – done at near atomic resolution using cryo-electron microscopy – reveals how the heavily mutated Omicron variant attaches to and infects human cells.
The S protein, which is located on the outside of a coronavirus, enables SARS-CoV-2 to enter human cells. The Omicron variant has an unprecedented 37 mutations on its S protein – three to five times more than previous variants.
A team of doctors and researchers working at Erasmus Hospital in Belgium has successfully treated an adult woman infected with a drug-resistant bacteria using a combination of bacteriophage therapy and antibiotics. In their paper published in the journal Nature Communications, the group describes the reasons for the use of the treatment and the ways it might be used in other cases.
Bacteriophages are viruses that infect and kill bacteria. Research involving their use in human patients has been ongoing for several decades, but they are still not used to treat patients. In this new effort, the researchers were presented with a unique opportunity not only to treat a patient in need of help, but to learn more about the possible use of viruses to treat patients infected with bacteria that have become resistant to conventional antibiotics.
Bacteria may Demonstrate any of Five General Mechanisms of Antibiotic Resistance:
1. Lack of entry; Decreased cell permeability.
2. Greater exit; Active efflux.
3. Enzymatic inactivation of the antibiotic.
4. Altered target; Modification of drug receptor site.
5. Synthesis of resistant metabolic pathway.
More than HIV, more than malaria. The death toll worldwide from bacterial antimicrobial resistance (AMR) in 2019 exceeded 1.2 million people, according to a new study.
In terms of preventable deaths, 1.27 million people could have been saved if drug-resistant infections were replaced with infections susceptible to current antibiotics. Furthermore, 4.95 million fewer people would have died if drug-resistant infections were replaced by no infections, researchers estimated.
Researchers say they have found a second patient whose body seemingly had rid itself of the human immunodeficiency virus (HIV) that causes AIDS — supporting hope that it may be possible someday to find a way to cure more people of the virus.
It’s Microbe Week, and we’re getting up close and personal with the wonderful world of the microbiome. The Museum is teaming up with a trio of awesome science shows— @sciencefriday,@braincraft, and @grossscience—for Microbe Week, featuring new YouTube videos and other content devoted to microscopic organisms and inspired by The Secret World Inside You exhibition. Today’s featured video, from GrossScience, is all about the microbiome of the mouth—and how keeping your microbes happy and healthy can help prevent cavities.
Watch the latest video, and stay tuned for more microbial videos this week!
We’ll be refreshing our dashboards daily for new microbial videos! Thanks, @amnhnyc!
