Mice help scientists ‘find cause of tinnitus’

American researchers claim that they have pin-pointed the cause of tinnitus – a breakthrough they believe could be a major step in understanding how to treat this life-changing condition.

Tinnitus is thought to afflict ten per cent of the British population. Symptoms commonly involve hearing ringing, and buzzing noises loud enough to impair hearing and seriously reducing the quality of life.

At-risk occupations

Workers who work with loud machinery, professional musicians and armed service personnel are all vulnerable to having their hearing affected by their occupation.

No win no fee solicitors such as Claims Direct can help people who need to make personal injury claims for hearing loss relating to accidents sustained in the workplace.

Over in America, the American Tinnitus Association reports that tinnitus is the most common service-connected disability among veterans of the Iraq and Afghanistan conflicts.

According to researchers at the University of Pittsburgh, it is only known that auditory circuits in the brain of tinnitus sufferers are more “excitable” than the circuits found in the brains of non-tinnitus sufferers.

But scientists have been unable to ascertain whether this is due to the hyperactivity of tinnitus sufferers’ auditory circuits or the reduced activity of their inhibitory circuits’ reflexes. This mystery has baffled scientists – that is, the Pittsburgh team say, until now…

Laboratory mice

The latest research concentrated on laboratory mice, half of whom were sedated and exposed to noise as loud as an ambulance siren for 45 minutes so that they would exhibit tinnitus.

‘Startle’ experiments

Confirmation of the tinnitus was confirmed by ‘startle’ experiments, where a continuously loud tone (60 per cent as loud as the siren) was played for a period then briefly stopped. Finally, an even louder tone was played at the end of the experiment.

The report, published in the online edition of the Proceedings of the National Academy of Science, revealed: “Mice with normal hearing could perceive the gap between the noises and, because they were aware something had changed, were less startled than mice with tinnitus, whose ear ringing masked the moment of silence in between the background tones.”

Conclusion

Further examination of the rodents’ brain patterns found that their tinnitus was caused by under-inhibition of key pathways in the brain rather than hyperactivity or over-sensitivity in other pathways.

Research leader Dr Thanos Tzounopoulos concluded that agents which increase inhibition “might be effective treatment for tinnitus” and his team is now trying to identify such drugs.

The Hairy Sand Ant

The so-called wood-boring wasps, Trypoxylon, which are not borers at all, but merely users of holes in any convenient substance, possess very weak poison, as I well know from having had it demonstrated upon me from the insect net. As for the semi-social, stout-bodied digging wasps of more than medium size, Bombex, it is said that they get into something of a rage when their nest is hastily approached, but do not attempt to use their stings. On the other hand the little burrowing bee-catchers, Cerceris and Philanthus, sting with such virulence that their bee and leaf beetle victims are killed at once. The gold wasps or cuckoo flies, Chrysididae, do not appear to possess poison glands; they rarely sting, even if taken by the fingers from the net. If defense is attempted it results in but a mere puncture like the deep prick of a fine needle.

A similar stab is given by certain larger, non-poisonous Ichneumonidae. No doubt the larger the insect the bigger its poison sac, but that does not seem to be the chief influence. We have an example of relative size and strength of venom as between the big sand hill hornet, Sphecius, and members of the hairy sand ant family, Mutillidae. These latter are, with the exception of the bumblebees, Bombus, the most virulent of all stingers. The length of their stilettos perhaps accounts in part for the severe result. The sand hornet makes victims of the cicada, as is well known; the sudden cessation of the husky homopter’s buzzing resistance after one quick stab attests to the deadly character of the poison injected.

The Mutilla minds its own peculiar business, its bright red and black colors warning hungry birds not to touch it. I have been stung once by each of these interesting insects, by the big sand digger on the thumb when she was going out of the net into a cyanide jar. The stab felt like the plunge of a red-hot needle; the bottle and lifted cork dropped, spilling the solution and liberating the valiant objector. But the hurt was not lasting and the member swelled but slightly.

I came into contact with the red and black hairy sand ant, Sphaerophthalma occidentalis, when beginning my active collecting efforts as a boy. There before me was a slowly running, gaudy thing that was some new kind of a hirsute ant and it was getting away toward a tangle of long grass. In that section there are no true ants that have stings; therefore, eager fingers closed on the creature. And unclosed! I hardly could believe the creature was not a whole and condensed beehive. I flung it from me and it got away. I have collected many of that species and others of its near relatives since, but tweezers have been used, or else the specimens sought have been made to run into an open cyanide jar.

Pests are something that needs to be identified at the early stage to avoid and inconvenience and health disorders caused by them. In this article we are going to see what the habitat, growth, life cycle and characteristic features of one of the most commonly found pest called Silverfish.

Scientific name of these silverfish is Lepisma saccharina. These are more frequently called as fish-moth, carpet shark, or as paramite and are tiny, insects without wings in the order Thysanura. These are also known to be silent and most usually the one that does not carry or transmit any diseases. The common name of this pest was supposedly derived from the creature’s silvery light grey and blue colors look and that mixed look like that of a fish-like outer shell and the actions. On the other hand the zoological nomenclature of this species is derived from the silverfish’s diet that comprises of carbohydrates such as sugar or starches.

These silverfishes are nocturnal creatures which have elongated, and flattened body structure which is most commonly between 0.5 and 1.0 inches in length. It can be noted that the abdomen of these insects tapers at the end and this is the factor that gives them a fish-like outward look. These insects are observed to be whitish when they are born, save for later on start to develop a grayish shade and metallic polish as they get older and older.

These insects normally have three extended cerci at the tip of their abdomen. One of the cerci will be parallelly lying to the body of them, another would be facing towards the left while the other would be facing towards the right. These wingless insects also have two compound eyes that are too tiny. The interesting factor to note here is that other that these silverfish of the order Thysanura, others are only being totally devoid of eyes, like that of the ones in family Nicoletiidae.

Silverfish are one among the pest insects that are totally devoid of wings. These pests can live for about two to eight years in a suitable atmosphere and can even stay alive without food for about one year.

Silverfish are the one among the pest that are less damaging to human health but most notorious in consuming materials that are made up of polysaccharides like that of starches and dextrin that is found commonly in adhesives. Substances like photos, paper, glue, book bindings, sugar, coffee, hair, carpet, clothing, dandruff and other stuffs that are rich in polysaccharides are the best place to live in and grow for a Silverfish.

There are a lot of simple and effective ways by which we can get rid of these mischievous silverfishes form homes and other places. It’s is very important to get rid of these pests when it comes to shops, book stores and libraries as they feed on them completely and make goods undesirable and useless. Hygiene and cleanliness is am important factor for getting rid of these pests but, not completely helpful in destroying the population of these insects because they most often are inherent and live in between wall partitions, insulation materials, books and papers, in the middle of book shelves within the other protected places that are in fact hard to trace for. Using pest sprays for the shelves and other suspected areas can keep them away from attacking the goods.
