Mitochondrial functions.

Illustration of hormonal levels during the menstrual cycle without fertilisation of the egg. The menstrual cycle repeats every 28 days or so. On the first day of periods, the brain starts to secrete FSH, whch stimulates the ovaries. For 14 days, this hormone favours the secretion of estrogen and the maturing of the future egg. A few days after ovulation, the brain starts to secrete LH. On the 14th day of the cycle, levels of LH in the blood are high : ovulation takes place and the ovary starts to secrete progesterone. This hormone thickens the uterine lining (the endometrium) and gets it ready to receive the egg. Under the effect of the progesterone, the brain progessively stops secreting FSH and LH : the ovaries diminish their production of estrogen, then progesterone, until the following cycle. The reduction of levels of all these hormones in the blood is responsible for triggering periods. The close up at top right shows what happens at the end of the luteal phase.

On STS-89, three Mechanics of Granular Materials (MGM) test cells were subjected to five cycles of compression and relief (left) and three were subjected to shorter displacement cycles that simulate motion during an earthquake (right). In the compression/relief tests, the sand particles rearranged themselves and slightly re-expanded the column during relief. In the short displacement tests, the specimen's resistance to compression decreases, even though the displacement remains the same. The specimens were cycled up to 100 times or until the resistive force was less than 1% that of the previous cycle. Sand and soil grains have faces that can cause friction as they roll and slide against each other, or even cause sticking and form small voids between grains. This complex behavior can cause soil to behave like a liquid under certain conditions such as earthquakes or when powders are handled in industrial processes.

This diagram presents some of the processes and clues related to a long-ago lake on Mars that became stratified, with the shallow water richer in oxidants than deeper water was. The sedimentary rocks deposited within a lake in Mars' Gale Crater more than three billion years ago differ from each other in a pattern that matches what is seen in lakes on Earth. As sediment-bearing water flows into a lake, bedding thickness and particle size progressively decrease as sediment is deposited in deeper and deeper water as seen in examples of thick beds (PIA19074) from shallowest water, thin beds (PIA19075) from deeper water and even thinner beds (PIA19828) from deepest water. At sites on lower Mount Sharp, inside the crater, measurements of chemical and mineral composition by NASA's Curiosity Mars rover reveal a clear correspondence between the physical characteristics of sedimentary rock from different parts of the lake and how strongly oxidized the sediments were.

Illustration of the Gleason grade system. The Gleason system is based on the degree of differentiation of a prostate tumour (graded from 1 to 5). It is the result of a microscopic study of cancer cells, which constitutes a score called the Gleason score. This score is the sum of two grades that are the most frequently represented in the analysed tumour. It varies from 2 to 10. The score 2 corresponds to a tumour that is very similar to benign tissue. The higher the score, the more aggressive the tumour. Grade 1 : Small, well differentiated glands, contained outbreak. Grade 2 : Regular glands in size and shape, ill-defined edges to the outbreak. Grade 3 : Various shaped and sized glands, irregular spacing, extremely ill-defined edges to the outbreak. Grade 4 : Fused glands, massive and with irregular edges. Grade 5 : Gland structure disappears.

Illustration of pulmonary compliance (volume difference / transpulmonary pressure difference) in a patient who is awake and standing, in a wakened lateral position and under general anesthetic (GA). In the standing position, the lungs behave like a spring that is held at the top. The aveoli at the bottom are better ventilated than those at the apex as their compliance is better. In a lateral position, the lower lung is better ventilated as it is positioned on a more favourable part of the compliance curve. A GA lowers the residual functional capacity, the lower part of the lung is on a less favourable level of the compliance curve, which increases problems in the ventilation/perfusion ratio.

The Critical Viscosity of Xenon Experiment (CVX-2) on the STS-107 Research 1 mission in 2002 will measure the viscous behavior of xenon, a heavy inert gas used in flash lamps and ion rocket engines, at its critical point. The sample cell at the heart of CVX-2 will sit inside a thermostat providing three layers of insulation. The cell itself comprises a copper body that conducts heat efficiently and smoothes out thermal variations that that would destroy the xenon's uniformity. Inside the cell, the oscillating screen viscometer element is supported between two pairs of electrodes that deflect the screen and then measure screen motion.

This graphic depicts paths by which carbon has been exchanged among Martian interior, surface rocks, polar caps, waters and atmosphere, and also depicts a mechanism by which it is lost from the atmosphere with a strong effect on isotope ratio.

The Diffusion-Controlled Apparatus for Microgravity (DCAM) was developed at NASA's Marshall Space Flight Center. A semi-permeable plug or fuse at the center controls the rate at which a precipitant diffuses from the reservoir chamber into the solution chamber , thus prompting protein molecules in the solution to form crystals. The principal investigator is Dr. Dan Carter of New Century Pharmaceuticals in Huntsville, AL.
