Coffee has evolved twice!

The coffee genome has just been published. Denoeud et al have sequenced the genome of coffee (biological name Coffea canephora). They found that within coffee’s 11 chromosome pairs, that there were many duplicated genes which include the one that code for the production of caffeine. They also suggested that these duplications enhance the products produced by the coffee plant to produce more effective proteins. The research also found that unlike tea and cacao (the chocolate component), the genes that code for the production of caffeine, in the coffee plant, are different to the genome sequence for the tea and cacao caffeine-producing enzymes, defining that the caffeine production genome has evolved at least two times. The genome sequence could help in research to help identify the genes that help the plant to combat diseases (related to the plant) and to also cope with climate change and to also encourage more delicious tasting coffee!

Combating E. coli Drug Resistance by Mutation

Bacterial mutation can be caused by a number of factors, such as genetic mutation and genetic transfer. This mutation causes them to become resistant to antibiotics, making life harder for researchers and starting a new strain of resistant bacteria which could potentially be life threatening.

There needs to be more research on Opioid painkillers and Enkephalins!

Chronic pain is something that most people have to go through every day, such as back pain caused by sciatica or other reasons, headaches, migraines or other neurological pains. To help get people through the difficult pain, several painkillers have been produced and a widely used such as codeine and morphine (sometimes codeine is given as co-codamol, a mix of codeine and paracetamol). 

Coffee: the Good, the Better and the Not-So-Good

Millions of people over the world start their day with an aromatic cup of coffee generally to wake them up.  Coffee contains caffeine which is the stimulant that interacts with the body to make you feel more alert. How Coffee works and its benefits Caffeine works as an antagonist (block receptors) of adenosine receptors in the brain. Caffeine mimics the natural neurotransmitter; adenosine, and blocks the receptor, preventing adenosine from binding to the receptor and slowing the nervous impulses. In turn this makes the nervous impulses quicker and the brain works faster. Also caffeine can relieve headaches and migraines since it binds to adrenergic receptors on vascular muscle cells which cause them to constrict instead of dilating.

A new hope for Parkinson’s disease …?

First of all I’d like to dedicate this blog post to my late uncle who was a victim of Parkinson’s disease. May he rest in peace… Parkinson’s disease was discovered by James Parkinson in 1867 and had initially called it “Shaking palsey”. Parkinson’s is the 2 nd most common neurodegenerative disease after Alzheimer’s, and can be identified by shaking hands (tremor), rigidity and posture instability; cased by the loss of neurons in the Substantia Nigra (in the brain), and the lack of dopamine (dopamine smoothes out skeletal muscle movements) due to the death of dopaminergic neurones in the Substantia Nigra (black substance) in the brain and also the accumulation of lewy bodies. Other symptoms of Parkinson’s are shuffling gait, depression and anger.

Coconut water: healthy or hype?

Social media is full of health gurus that are obsessed with healthy eating and exercise and what they can drink to maintain their energy during workouts. This is where coconut water comes in. Coconut water (biological name Cocos nucifera L.) is sometimes compared to energy drinks and glorified about for its great benefits and hydrating properties. It is even now more widely available in grocery stores than previous years. The hydrating drink is known to have a bunch of nutritious benefits and is harvested from green coconuts that are still unripe. Coconut water is low in calories, rich in antioxidants and electrolytes (such as the inorganic ion: potassium), it is also low in fat and cholesterol free and has elevated amounts of vitamin C .

Should we fear the Ebola virus or not?

“Breaking news: Ebola virus has been declared as an international public health emergency by the World Health organization” That sentence was the first thing I saw when I logged into Facebook as I’ve started planning and writing this article. What is the Ebola virus (EBOV)? BBC Ebola Virus The Ebola virus is a very terrible disease and lethal if caught and it has a high fatality rate of 60% (WHO 01/04/2014) [1] Ebola is not an airborne virus but it can be spread via bodily fluids such as sweat and its recommended that you don’t shake hands with anyone who could potential carry the disease or has recovered and still in recuperation period.
