A crown group is a living group, or , consisting of the last common ancestor of all living examples, plus all of its descendants. The name was given by , the formulator of , as a way of classifying living organisms relative to extinct ones. Extinct members of crown groups are included. Because the , although extinct, is still descended from the last common ancestor of all living birds, for example, it is nevertheless included in the bird crown group.

Stem and crown group terminology

However, some organisms fall outside the crown group at a particular level, and these require an extra systematic category to include them. A good example is which, although clearly bird-like, is not descended from the last common ancestor of all living birds, being instead more basal than any of them. Such organisms can be referred to the of a clade (a term introduced by the palaeontologist Dick Jefferies). In this example is a stem-group bird. All organisms more closely related to crown-group birds than to any other living group are referable to the bird . As living birds are by definition in the crown group, it follows that all members of the stem-group of a clade are extinct; and thus, stem groups only have fossil members.
The same applies for , a marine fossil crocodile. It is a member of the stem group of all extant crocodiles because it shares less characters with the of gharials and alligators than the saltwater crocodile Crocodylus porosus or some geolocically younger fossil crocodiles do.

Stem and crown groups are hierarchical; thus, an extinct crown-group bird may lie in the stem group of a subset of the birds, such as the ; and stem-group birds lie, together with crown group birds and crocodiles and several extinct groups, in the crown group of the . Thus all extinct organisms lie in a stem group of some living crown group. A crown group and its stem group considered together are known as the (or pan-group). Although the stem group is , it can be objectively defined by subtracting the crown group from the total group.

Stem groups offer a route to classify fossils that otherwise do not obey systematics based on living organisms. Stem group organisms always lack one or more features that are present at the base of the crown group to which they are attached. Thus, Archaeopteryx still retains teeth, unlike crown-group birds. As a group evolves away from the last common ancestor of it and its nearest living relative, it accumulates the distinctive features of its crown group. Hence, the last common ancestor of birds and crocodiles – the first crown group archosaur -was neither bird nor crocodile, and possessed none of the distinctive features of either. However this first crown group archosaur is defined by the characters shared by living birds and crocodiles. Evolution up the bird stem group then allowed accumulation of distinctive bird features such as feathers, the beak and hollow bones, until all were finally present at the base of the crown group.

Placing in their right order in a stem group allows the order of these acquisitions to be established, and thus the ecological and functional setting of the evolution of the major features of the group in question. Stem groups thus offer a route to integrate unique palaeontological data into questions of the evolution of living organisms. Furthermore, they show that fossils that were considered to lie in their own separate group because they did not show all the diagnostic features of a living clade, can nevertheless be related to it by lying in its stem group. Such fossils have been of particular importance in considering the origins of the , , and , among others.

The crown group concept is thus also helpful avoiding confusion in taxonomic nomenclature. This particularly refers to the different extent of clades that are named identically in systematic biology and paleontology. For example the clade in different literature is defined (1) by the common ancestor of ostrich and sparrow (the crown group proper) (2) by the common ancestor of sparrow and (3) as sister clade of the crocodiles, and in two cases as clade defined by apomorphic features, namely (4) feathers and (5) flight capability or corresponding anatomical features in fossils. The concept of crown groups or pan-groups, respectively, provides the opportunity to set priorities in definition and extent of higher taxa.

Although the hallmark feature of MDSCs is immunosuppression, emerging data reveal that the degree of immunosuppression varies among populations of MDSCs isolated from different organs, with intratumoral MDSCs being the most immunosuppressive. Interestingly, these MDSCs express greater levels of NOS2 and ARG1 than their splenic counterparts (5). ARG1 expression is mainly regulated by the STAT-6IL-4R pathway (30). We recently correlated IL-4R expression on CD11b+/Gr-1+ with an immunosuppressive phenotype (29), and our in vitro data (Fig. 5) indicate that sildenafil down-regulates IL-4R on MDSCs. We then asked whether in vivo PDE5 inhibition reduced ARG1 and NOS2 and down-regulated IL-4R in tumor-associated MDSCs. BALB/c mice were challenged with CT26WT, and half were treated with sildenafil. Mice were killed 15 d later, and intratumoral MDSCs were obtained. Sildenafil increased cGMP (Fig. 6 A), reduced IL-4R expression (Fig. 6 B), and down-regulated NOS2 and ARG1 expression and reduced their enzymatic activity in the intratumoral MDSCs (Fig. 6, C and D). Considering that ARG1 and NOS2 are key enzymes in MDSC suppressive pathways (8, 31), these findings support the hypothesis that PDE5 inhibition is a novel pharmacologic approach to regulate MDSC-mediated immunosuppressive pathways. Very limited effectiveness There's no known cure for the disease, and medications primarily take aim at symptom relief and slowing the progressive disability the illness brings. The rich database of the Massachusetts Male Aging Study has allowed important insights to be gained into a variety of risk factors for erectile dysfunction, both psychosocial and physical. A submissive personality was associated with a higher risk of erectile dysfunction. Obesity status was also associated with the condition (p = 0.006), with baseline obesity predicting a higher risk regardless of follow-up weight loss. Smoking and alcohol consumption were not found to be causally associated with the incidence of erectile dysfunction. The risk of the condition was higher among men with lower education levels, diabetes, heart disease and hypertension. Treatments (with the exception of testosterone supplementation, where effective) work on a temporary basis: they enable an erection to be attained and maintained long enough for intercourse, but do not permanently improve the underlying condition. Online supplemental material. And a study of 370 seized "Viagra" samples carried out by the Dutch National Institute for Public Health found that only 10 were genuine, with a range of other drugs present in the samples. How is ED treated? WEDNESDAY, July 19 (HealthDay News) -- Impotence is more prevalent among men who have more severe coronary artery disease than among men with low levels of the disease. Surgery to repair arteries can reduce ED caused by obstructions that block the flow of blood. The best candidates for such surgery are young men with discrete blockage of an artery because of an injury to the crotch or fracture of the pelvis. The procedure is almost never successful in older men with widespread blockage. A health treatment that is not classified as standard Western medical practice is referred to as "alternative" or "complementary." Alternative treatments include nutritional supplements, herbal remedies, and acupuncture. Who's Blogging An increasing array of medications is available to assist in the management of erectile dysfunction (ED). New agents are still undergoing clinical testing, and more are in the early phases of development. Success rate of 70-80% "We would anticipate that tadalafil will be reviewed and approved by the regulatory agencies as an additional therapy available for the treatment of pulmonary hypertension," Barst said. "It is useful for the treatment for pulmonary hypertension, as for many other diseases, to have more than one drug per class approved, due to individual patient responses and side effects," she added.
