As a family physician, I have been blessed to stand witness to the bookends of life. From womb to tomb, it has been an incredible experience to see families bringing life into the world and supporting those who are passing on. We physicians also get to closely observe the journey in between: the shots, the first tooth, the first step, the runny nose, the hospital stay, the developing athlete, the evolving scholar, the budding artist, the graduations, first job, weddings and other major life events. Our patients truly become our extended family.
As doctors globally are warned that overconsumption of antibiotics has led to resistance to the drug – medical researchers are equally focussed on finding alternatives to treatments for bacterial infections, particularly with the rise of 'superbugs' such as multi-drug resistant Staphylococcus aureus (MRSA), which are resistant to current drugs.
Researchers at Umeå University in Sweden have discovered that specific DNA sequences that are rich in the DNA building block guanine in the yeast species, Schizosaccharomyces pombe, can form four-stranded DNA. In a study published today in the journal Nucleic Acids Research, the researchers also show that the motor protein Pfh1 can unfold these DNA structures and thus contribute to maintaining an intact genome.
