Range: Late Triassic () to () of Europe for Dimorphodon. Inclusion of Sordes extends range to Asia and the . Various unconfirmed bits and pieces suggest a worldwide distribution.

Phylogeny: Pterosauria: (Campylognathoidea + (Rhamphorhynchoidea + Pterodactyloidea)) + *.

Introduction: , from the of Lyme Regis, Dorset, and Aust Cliff, Gloucestershire is the only certain member of the family Dimorphodontidae. Only a few specimens are known; all but one (the one illustrated) coming from the Sinemurian of the Dorset Coast of England.

This primitive pterosaur had quite a large, deep skull that was also very lightly built, consisting of large openings separated by narrow strips of bone. The tail was long, with the first five or six vertebrae short and flexible, and the rest elongated and stiffened against each other by long strips of bone. The tail was thus a long stiff rudder, flexible only at the base, and used for stabilization in flight. The overall length was up to 100 cm, with a wingspan up to 1.4 metres. The hind legs were long and powerful, indicating that Dimorphodon was able to walk competently on land, bird or dinosaur fashion. (MAK 991008)

Characters: medium-sized; large, deep skull; does not extend posteriorly to the level of the ; breaks contact between ascending process of maxilla and ; cranial struts very thin; tiny; tail long; first five or six short and flexible, and the rest elongated and stiffened against each other by long strips of bone (tail used as rudder, flexible only at base); sternal complex wider (laterally) than deep; deltopectoral crest with bulbous distal expansion [P&S]; roughly equal in length; large wing claws; legs long; metatarsals tightly appressed; attached to ankles and uropatagium even to toes in Sordes [U99].

Notes: [1] the name is derived from the dimorphic teeth: large conical stabbing teeth anteriorly, and tiny pointed teeth posteriorly. However, many types of pterosaur developed similar specializations and this particular trait may be characteristic of the pterosaurs as a whole. [2] Sordes is variously classified as just basal to this group, as a dimorphodontid, or as a rhamphorhynchoid (U&B). Nesodactylus is known from a rather incomplete specimen from the Late Jurassic of Cuba. [3] Sordes has also been at the heart of the controversy relating to wing attachment, with Unwin and others using some of these beautifully preserved specimens to show that the wing was attached far down the ankle, as well as extending between the legs, making bipedal locomotion almost impossible.

Mostly Cretaceous forms.

Range: upJ-upK.

Phylogeny: Pterosauria::: Rhamphorhynchidae + *: + ( + ( + )).

Introduction: advanced forms from the Late Jurassic and Cretaceous. Small to very large. Short tails. The neck is longer (although with the same number of vertebrae) and the brain is larger. In some forms a head crest developed to aid in manoeuvourability during flight. The teeth are reduced and sometimes absent.

Characters: all relatively large as adults [B96]; skull elongate & laterally compressed [K&L]; cranial bones usually fused in adults; jaws triangular with tendency to lose teeth [P97]; premaxilla usually forms anterodorsal portion of skull, including at least part of [K&L]; lies below premaxilla and forms sides of upper jaw and anteroventral margin of ; absent or confluent with antorbital fenestra [K&L][P97]; cranial crests [B96]; of helical in some large forms [K&L]; anterior trunk vertebrae fused into ; tail reduced or absent (maneuverability); scapula curved inward and articulated with notarium (stronger flight stroke) in larger species [P&S]; directed posterolaterally (rather than laterally) since now formed parts of a ring structure with sternum and notarium; metatarsals flexible --appressed for flying & spreadout for walking [B97]; outer layer of bones 1-2 mm in large forms, supported by internal struts [K97]; integument very thin, probably without scales or "hairs" [K97]; at least small forms probably quadrupedal, using manus digits 1-3 spread laterally or retrograde [B97].

Discussion: In the brief period between about 1980 and 2000, evolved from long-extinct, slumbering mountains of swamp-dwelling flesh -- barely swifter than continental drift -- to hot-blooded athletes who dominate the skies even today. We will pointedly ignore the question of whether this reinvention of the taxon has gone just a shade too far. The astounding success of the general reinterpretation can legitimately cause us to wonder whether even the most outlandish claims for the abilities, metabolism, prowess and intelligence of the dinosaurs might not turn out to be well founded after all. But every success breeds imitators, and not every imitation matches the quality of the original. The pterosaurs, who underwent a parallel transformation in the scientific literature, now seem to be devolving back into a more traditional mold.

For a while, in the early 1990's, it seemed that pterosaurs were almost more birdlike than birds. They were characterized as active, deep-keeled, flapping flyers in the air and as lithe bipedal runners on land. They were covered with hair and distinctly warm-blooded. Their wings were narrow and held in place by rods of some unique and advanced design. They were loving parents who engaged in extended care of their chicks [1]. They finished the Times crossword before their second cup of coffee went cold. The name of Kevin Padian [2] is frequently invoked for this interpretation, although it would be unfair to ascribe the more extreme expressions of these views to Prof. Padian.

It all seemed a little too good to be true -- and it probably was. One stumbling block is , probable pterosaur footprints from Arizona and Wyoming. Similar prints have been found in France. Actually, the track maker was not stumbling, but it was certainly not a biped. Nor does it appear to have been an ordinary quadruped. Padian showed that similar tracks could be generated by , specifically by , under appropriate experimental conditions. However, the appropriateness of these conditions has been criticized, as has the similarity of the prints. See, e.g., Bennett (1997) and Unwin (1999). It has been reported that Padian has also recently stated that certain similar are probably pterosaurian.

If this is correct, then pterosaurs were not only quadrupeds, but probably somewhat sprawling quadrupeds who walked a bit awkwardly on plantigrade feet and almost retrograde fingers. Perhaps this proves too much, since it is hard to see how a really large pterodactyloid could have moved in this manner. But, then again, it is hard to see how something like could have moved in any manner on the ground. It is probably safe to say that pterosaurs were not cursorial bipeds, but distinctly hazardous to say much more than that.

Another difficulty has been the beautifully preserved remains of Sordes from and of more exotic species from the Brazilian . The pterosaur "hair" is probably internal membrane fibers, the main wing membrane (brachiopatagium) was fastened well down the leg, and a distinct joined the legs, held in place by the retroverted fifth toe. If pterosaurs ran, they did so in heavy floor-length gowns. As any reasonably articulate feminist will be happy to explain, the whole point of such attire is to make it more difficult either (a) to get anywhere or (b) to accomplish any useful work. I hasten to disclaim any opinion on the politics and intent, if any, of gender-specific fashion statements -- although it is interesting that traditional academic garb is designed along the same lines -- but one is forced to concede the practical consequences. A fully accoutered pterodactyloid might manage a stately pavan, but was clearly not designed for the ptango.

Unwin goes so far as to suggest that this deconstruction of the pterosaurs might require us to place pterosaurs back among the basal archosauromorphs or even in the basal , a theory that was worked out in some detail by Peters in the sadly missed Pterosaur Home Page and various JVP abstracts. Unfortunately almost all pterosaur phylogenetic work is published in the form of JVP abstracts, so it is difficult to comment. Unwin cites work by Bennett for the idea that only characters of the hind limb place Pterosauria among ornithodires. However, this is a little unfair since Ornithodira, as well as the clades it contains, largely reflect key transitions in hind limb locomotion. The growth of this whole branch of the Tree seems to have been driven by hind limb design. See, e.g., Hutchinson & Gatesy (2000), Novas (1996), and review by White (2001). Thus, it may be meaningless to speak of ornithodires without ornithodire hind limbs. It is only a slight exaggeration to say that ornithodires are all archosauromorphs with the specialized ornithodire hind limb. However, it may be possible that the ornithodires are cursorial descendants of little gliding or even flying archosaurs, and that the pterosaurs were an early radiation of that line. This is sheer speculation, of course, but it has the advantage of accommodating all schools of thought and even providing a little vindication to the much reviled work of John Ruben. See, e.g., Jones et al. (2000).

[1] Oddly enough, this part is still very likely true. See Bennett (1997).

[2] In the interests of full disclosure, I should state that I hold, and have strongly expressed, negative opinions about Dr. Padian's statements on certain subjects. These subjects are not among those discussed anywhere in Palæos, but the reader is duly warned of a potential bias. (ATW 011012.)

In addition, many common medicines—blood pressure drugs, antihistamines, antidepressants, tranquilizers, appetite suppressants, and cimetidine (an ulcer drug)—can produce ED as a side effect. If you feel you need supervision or medical advice to begin an exercise program, ask your doctor to refer you to physical therapy. A physical therapist can evaluate your needs and start you on a safe and effective exercise program. The vaccine consisted of 106 -irradiated CT26 or C26GM cells injected s.c. For ACT experiments, mice were vaccinated on days –14 and –7 before ACT in all four limbs with 106 -irradiated C26GM. The CD8+ T cells were negatively purified using the CD8+ isolation kit (Miltenyi Biotec), and 3 x 106 CD8+ T cells were transferred per mouse. In the 4T1-HA experiments, HA-specific CD8+ naive T cells were isolated from spleens and lymph nodes of pCL4-TCR mice. Erectile Dysfunction and High Blood Pressure Although sildenafil can increase cGMP in T cells, DCs, and CD11b+ cells (Fig. 5), the following data indicate that Gr-1+/CD11b+ MDSCs are its primary cellular target. Gr-1 depletion does not augment sildenafil-mediated antitumor activity (Fig. 6 E), and sildenafil down-regulates MDSC suppressive pathways in vivo (Fig. 6, B–D). Moreover, sildenafil reverses MDSC suppression in vitro (Fig. 7). MDSCs and/or tumor-associated macrophages have been shown to induce apoptosis or anergy in CD8+ and CD4+ T cells through NOS2- and/or ARG1-dependent mechanisms (34). In fact, NO production anergizes Th1 cells through inhibition of IL-2 signaling (34). Alternatively, in a mixed Th1/Th2 cell environment where ARG-induced pathways also mediate immunosuppression, MDSCs produce NO and super-oxide radicals to generate peroxynitrites that induce apoptosis of activated CD8+ T cells (9). A greater understanding of the role of MDSCs in tumor-induced immune dysfunction (7, 42) will establish the scientific rationale for a targeted pharmacologic approach to disrupt these suppressive mechanisms and may serve as an adjunct to immunotherapy. We previously showed that nitroaspirin could abrogate the inhibitory activity of MDSCs by enhancing the preventive and therapeutic efficacy of antitumor vaccines (43). However, despite its use as a vaccine adjuvant, nitroaspirin demonstrated no antitumor efficacy when used alone. In contrast, down-modulation of both ARG1 and NOS2 in MDSCs (Fig. 6) with PDE5 inhibitors effectively abrogates MDSC-mediated immune suppression, resulting in a measurable antitumor response (Fig. 1, Fig. 3, and Fig. 4). We have recently shown that to effectively exert their suppressive function, MDSCs must (a) be activated by IFN- production from antigen-stimulated T cells, (b) release their own IFN-, and (c) be responsive to IL-13 (29). Cooperation between these two cytokines leads to the activation of ARG1 and NOS2 enzymes. Sildenafil neither alters IFN- production from activated lymphocytes (not depicted) nor changes IL-13 and IFN- production from MDSCs (Fig. S6, available at Rather, PDE5 inhibition down-regulates IL-4R expression on MDSCs (Fig. 5 and Fig. 6), likely impairing their responsiveness to IL-13. Jason L Iltz, PharmD * End premature ejaculation for good. What Causes Erectile Dysfunction (ED)? Add Rigid implant He'd like to do a study with men who have confirmed restless legs syndrome to better test the potential link. The men handling BPA were four times as likely to suffer from erectile dysfunction and seven times as likely to have difficulty with ejaculation, said De-Kun Li, a scientist at the Kaiser Foundation Research Institute, which conducted the study with funds from the National Institute for Occupational Safety and Health.
