Medical officials have discovered that chemical make-up of malaria patients' breath has peculiar
properties which make diagnosis by breath a train of thoughts. “Malaria”
at first came from Italian words for "bad air" because it was mused
that disease was caught from the foul smelling air around swamps &
marshes. The chemicals are hard-nosed, but with proper
instruments, disease can be diagnosed earlier than with standard blood
examination method. Higher levels of four sulfur compounds were
detected in direct correlation with severity of the infection.
Researchers have faith on this discovery &
presume that it will help develop a fast & economical system of malaria
detection. As world starts to work
towards calling all bets off malaria, it is the standout priority for more
sensitive & convenient tests to detect hidden cases. In compatibility with World
Health Organization (WHO), around 200 million cases of malaria & half a
million malaria deaths were recorded in 2013. Prompt
diagnosis would not only unshackle lives of people but could also help slash spread
of malaria as they can help transmit infection even before the symptoms become
evident.Jounce in Diagnosis
Bringing mosquitoes that produce 95% male offspring
into existence by using a sex-distorting genetic defect may also help control
malaria. Malaria is out landed by a parasite called a Plasmodium & is spread
by female Anopheles mosquitoes. This female mosquito picks up parasite from infected
people when they suck blood needed to nurture their eggs. An imprint on the
genetics control strategy, the technique works by shredding the X chromosome
during sperm production – leaving behind the few X-carrying sperm to strictly produce
female embryos only. This cuts the number of mosquitoes able to spread disease.
Hunting
for Malaria with Magnets!
Red blood cells don’t
have nuclei. Any that show up are predicated to belong to parasite cells. The
technology & expertise needed to identify the parasite are not always
available in some of regions mostly affected by malaria. This new nervy system
catches a parasitic waste product called hemozoin. Hemoglobin breaks down
releasing iron, which can be toxic, so the parasite converts iron into hemozoin
— a weakly paramagnetic crystallite. Researchers used a
0.5 T (Tesla) magnet which is much less expensive & yet powerful than 2- or
3-tesla magnets.
Detecting without Blood Draws
Study Abstract -Proceedings of National Academy of Sciences. This research says that high optical absorbance & nano size of endogenous hemozoin generates a transient vapor nano-bubble around hemozoin in response to a short & safe near-infrared picosecond laser pulse. This gave rapid detection of a malaria infection as low as 0.00034% in animals without using any reagents or drawing blood. This device is easy-to-use, compact, inexpensive, & safe field technology.
Perform regular health check-ups and avoid malaria.
