July 17, 2013. During the shooting of the seabed in the autumn of last year, the scientists on board the survey vessel noticed bubbles rising from the depths. Phenomenon has aroused interest marine biologists, and they sent to their place of interest expedition. Here, they found out that the seabed in the form of methane gas bubbles coming out and the vicinity of this space filled with a variety of life forms.
A study by researchers revealed that on the ocean floor at depths of up to 1.6 kilometers inhabited by whole colonies of bacteria that are used for life energy of destruction of methane. Read more [...]
Some underwater volcanoes do not erupt and spit out giant blobs of lava, like all well-known gel lamps.Until now, scientists have divided the eruption in two categories: violent (explosive) and effusive. The first type involves adorable kids ejection of ash and rock fragments high into the atmosphere (for example, the eruption of Mount St. Helens in 1980). Second - soft red hot lava flows that irrigate the slopes of the volcano (this, for example, are constantly in Hawaii).
Pumice stone to get to the unusual underwater volcano near McAuley in the southwest Pacific, the staff of the University Read more [...]

The size and depth of burn wound duration dependent, the size and nature of the resulting scars. Extensive, rough, astringent scars are the cause of development of contractures, deformation, etc. Sometimes remain stubbornly healing granulating defects - ulcers, surrounded scar.
In extensive burns, II and III A degree is not complicated by suppuration, sometimes there is only the first period of burn disease - burn shock. Nenagnoivshiysya burn II degree heals by forming a young epidermal peel off (ie, at the bottom of the bubbles). Healing occurs 7-14 days and cicatricial changes of the skin, Read more [...]
Pemfigoidnye elements represent a bubbles of different size - the size of a pea to a walnut, filled with serous-purulent contents. Bubble shell is very thin.
The disease begins with the appearance of the skin of one or more of these elements, which tend to be further spread. In some cases, rash may be limited to just one or two items. Shortly after rashes some bubbles subside and gradually dry up, others burst, exposing the eroded surface. Epithelization erosion occurs rather quickly.
Pemphigus is a highly contagious disease and often leads to outbreaks. Children who become ill with pemphigus, Read more [...]
This form is characterized by the appearance of pyoderma on the skin of small white bubbles the size of a pinhead or millet seed. The preferential localization of them - forehead, torso and groin. The contents of the first transparent bubbles, then rapidly becomes purulent. After a few days of starting the rash they burst or regress.
Vezikulopustuleza treatment is as follows. Bubbles removed with a cotton swab moistened with 96% alcohol, followed by blurring the base alcohol solutions of methylene blue or brilliant green. Cautery can restrict these bubbles colors without opening them. Skin Read more [...]
Echinococcosis - helminthiasis associated with the penetration and development of Echinococcus it in tissues and organs.
Etiology. Pathogens are human echinococcosis hydatid echinococcus (Echinococcus granulosus), causes hydatid form and alveolar echinococcus (Echinococcus alveolaris), causing alveolar echinococcosis form (see Alveococcosis). An adult tapeworm stage - small cestode (tape worms) length 2.5-5.5 mm. Cestode consists of scolex (head), armed double row of hooks, neck and 3-4 segments. The last segment is filled with mature uterus, stuffed eggs. Definitive hosts of the worm are dogs, Read more [...]
Erythema - redness of the skin is caused by a reflex or inflammatory hyperemia. In arterial hyperemia erythema a rose-red color, with venous she gets bluish tint (congestive erythema). Unlike hemorrhage, erythema disappears from the pressure on her finger or glass. Foci erythema of up three-kopeck coins called roseola, erythema all skin - erythroderma (see).
Common cause of erythema are different chemicals, friction, pressure, heat, cold, UV light, ionizing radiation, bacteria, pathogenic fungi, some plants. Erythema may be a manifestation of common infectious diseases (measles, scarlet fever, Read more [...]
Embolism - a blockage of the blood vessels is the solid particles, droplets of oil or gas bubbles. Accordingly, the distinction embolism by various solids (thrombosis, embolism particles tumor hydatid bubbles or their parts, etc.), fat embolism and gas embolism.
In addition, the distinction embolism pulmonary circulation (venous embolism) and embolism of the systemic circulation (arterial embolism).
Most often embolism occurs when venous thrombosis (see). Part removed a blood clot (mainly from the veins of the lower limb, pelvis) is carried away through the right side of the heart to the pulmonary Read more [...]

Intertriginoznoy athlete has the form of diaper rash. Fungi penetrate the stratum corneum between the 4 th and 5 th fingers or between the 3rd and 4th toes. Since these fingers close together, fungi proliferate faster here. The disease begins with mild redness in the center of which will soon appear crack here and there - tiny bubbles. But these little worried carrier as itching initially not. With progression redness moves to the back surface of the fingers, clearly standing out for its contoured edges, as well as itching, burning, pain, swelling.
However, not all forms of athlete proceed Read more [...]
"Pearl" (air-gas) bath is prepared by passing air, compressor pumped through tubes with small holes, reinforced in the lattice, which lies at the bottom of the tub. The air coming out of the holes under pressure, causing swirling water. Bath got its name because the air bubbles, shimmering in the water, reminiscent of pearls. The presence of large bubbles increases thermal and mechanical stimulation of the nerve endings in the skin, but the hydrostatic pressure decreases. These baths are easier to carry than fresh, the water temperature is 36 ° C. They have a tonic, and sometimes Read more [...]
