ISLAMABAD - The health experts in a recent study have found dangerous aspects of using lemon slices in daily drinks and warned its stoppage as it can cause serious health issue.

According to a study, researchers swabbed lemon slices that were put into their drinks at 21 different restaurants, a private news channel reported.

They discovered that the practice was being done because it makes drinks taste fresh but they have warned that adopting such habit may cause serious health problem as the fruit used, tends to be really dirty .

Moreover, they found that almost 70% of those samples produced some kind of microbial growth, and included 25 different microbial species.

The researchers wrote that “The microbes found on the lemon samples in our investigation all have the potential to cause infectious diseases at various body sites, although the likelihood was not determined in this study.

Gene-editing method

shrinks cancer

Crispr-Cas9 replaces harmful DNA with new code that kills cancerous cells while leaving healthy ones unharmed.

Mice with the reprogrammed code developed tumours that were much smaller than cancers in mice that did not get this treatment.

Experts call the study promising but say it is unclear yet whether the technique would work in humans.

Dr Weiren Huang, from the First Affiliated Hospital of Shenzhen University, in China, and colleagues used Crispr-Cas9 to reprogram a cell-signalling pathway that would normally feed tumour growth in mice.

Crispr-Cas9 is a DNA cutting and pasting system scientists have borrowed from nature.

Bacteria use it to protect themselves against foreign DNA from viruses.

Scientists have already begun using it in the lab to target and cut out faulty DNA in human cells that cause illnesses.

But it is not without risks.

While effective, the editing process is less than perfect and can cut out too much DNA.

Alzheimer’s drug study gives

‘tantalising’ results

A drug that destroys the characteristic protein plaques that build up in the brains of patients with Alzheimer’s is showing “tantalising” promise, scientists say.

Experts are cautious because the drug, aducanumab, is still in the early stages of development. But a study has shown it is safe and hinted that it halts memory decline.

Larger studies are now under way to fully evaluate the drug’s effects.

The build-up of amyloid in the brain has been a treatment target for many years.

This study, of 165 patients, was designed to test aducanumab was safe to take. After a year of treatment, it also showed the higher the dose the stronger the effect on amyloid plaques.

The researchers then carried out tests on memory and found “positive effects”.

However, 40 people dropped out of the study, half because of side effects they experienced, such as headaches. These too were much more common with a higher dosage.

The next phase of research - phase 3 - involves two separate studies. These are recruiting 2,700 patients with very early stage Alzheimer’s across North America, Europe and Asia in order to fully test the drug’s effect on cognitive decline.
