Bone resorption induced by parathyroid hormone is strikingly diminished in collagenase-resistant mutant mice. (1/2390)

Parathyroid hormone (PTH) stimulates bone resorption by acting directly on osteoblasts/stromal cells and then indirectly to increase differentiation and function of osteoclasts. PTH acting on osteoblasts/stromal cells increases collagenase gene transcription and synthesis. To assess the role of collagenase in the bone resorptive actions of PTH, we used mice homozygous (r/r) for a targeted mutation (r) in Col1a1 that are resistant to collagenase cleavage of type I collagen. Human PTH(1-34) was injected subcutaneously over the hemicalvariae in wild-type (+/+) or r/r mice four times daily for three days. Osteoclast numbers, the size of the bone marrow spaces and periosteal proliferation were increased in calvariae from PTH-treated +/+ mice, whereas in r/r mice, PTH-induced bone resorption responses were minimal. The r/r mice were not resistant to other skeletal effects of PTH because abundant interstitial collagenase mRNA was detected in the calvarial periosteum of PTH-treated, but not vehicle-treated, r/r and +/+ mice. Calcemic responses, 0.5-10 hours after intraperitoneal injection of PTH, were blunted in r/r mice versus +/+ mice. Thus, collagenase cleavage of type I collagen is necessary for PTH induction of osteoclastic bone resorption.  (+info)

Lipoma of the corpus callosum. (2/2390)

Lipoma of the corpus callosum is a rare congenital condition, often asymptomatic, but which may present as epilepsy, hemiplegia, dementia, or headaches. This paper reviews the condition and reports the only two cases which are known to the Hospital for Sick Children, Great Ormond Street, London. The second case demonstrated the value of computerised axial tomography (EMI scan) in making the diagnosis and showing associated anomalies.  (+info)

Ocular development and involution in the European cave salamander, Proteus anguinus laurenti. (3/2390)

The anatomy and development of the eye of Proteus anguinus are described. The relationships between organogenesis of the eye in embryos and larva and its involution in the young and the adult are discussed. The availability (in breeding cultures) of a significant number of Proteus embryos (which are normally rare) allowed experimental analysis of the effects of light, xenoplastic differentiation and thyroid hormones on the development of the eye. The results of this study suggest that development and involution of the eye of Proteus are controlled by genetic factors which are not greatly influenced by environment, and one can, therefore, consider the microphthalmy of Proteus as a relict characteristic which is the result of a specific development with disturbance of the normal ontogenic process.  (+info)

Neural crest can form cartilages normally derived from mesoderm during development of the avian head skeleton. (4/2390)

The lateral wall of the avian braincase, which is indicative of the primitive amniote condition, is formed from mesoderm. In contrast, mammals have replaced this portion of their head skeleton with a nonhomologous bone of neural crest origin. Features that characterize the local developmental environment may have enabled a neural crest-derived skeletal element to be integrated into a mesodermal region of the braincase during the course of evolution. The lateral wall of the braincase lies along a boundary in the head that separates neural crest from mesoderm, and also, neural crest cells migrate through this region on their way to the first visceral arch. Differences in the availability of one skeletogenic population versus the other may determine the final composition of the lateral wall of the braincase. Using the quail-chick chimeric system, this investigation tests if populations of neural crest, when augmented and expanded within populations of mesoderm, will give rise to the lateral wall of the braincase. Results demonstrate that neural crest can produce cartilages that are morphologically indistinguishable from elements normally generated by mesoderm. These findings (1) indicate that neural crest can respond to the same cues that both promote skeletogenesis and enable proper patterning in mesoderm, (2) challenge hypotheses on the nature of the boundary between neural crest and mesoderm in the head, and (3) suggest that changes in the allocation of migrating cells could have enabled a neural crest-derived skeletal element to replace a mesodermal portion of the braincase during evolution.  (+info)

Intrameatal aneurysm successfully treated by meatal loop trapping--case report. (5/2390)

A 77-year-old female presented with a rare intrameatal aneurysm manifesting as sudden onset of headache, hearing loss, tinnitus, and vertigo associated with subarachnoid hemorrhage. Meatal loop trapping was performed. After surgery, the patient's functions recovered almost completely, probably because of the preservation of the 7th and 8th cranial nerves and the presence of effective collaterals in the area supplied by the anterior inferior cerebellar artery.  (+info)

New evidence from Le Moustier 1: computer-assisted reconstruction and morphometry of the skull. (6/2390)

In this study, we present a new computerized reconstruction of the Le Moustier 1 Neanderthal skull and discuss its significance for Neanderthal growth and variability. Because of the precarious state of preservation of the original material, we applied entirely noninvasive methods of fossil reconstruction and morphometry, using a combination of computed tomography, computer graphics, and stereolithography. After electronic restoration, the isolated original pieces were recomposed on the computer screen using external and internal anatomical clues to position the bone fragments and mirror images to complete missing parts. The inferred effects of general compressive deformation that occurred during fossilization were corrected by virtual decompression of the skull. The resulting new reconstruction of the Le Moustier 1 skull shows morphologic features close to the typical Neanderthal adult state. Residual asymmetry of skeletal parts can be traced to in vivo skeletal modification: the left mandibular joint shows signs of a healed condylar fracture, and the anatomy of the occipital region suggests mild plagiocephaly. Using micro-CT analysis, the left incus could be recovered from the matrix filling of the middle ear cavity. Its morphometric dimensions are similar to those of the La Ferrassie III incus. The morphometric characteristics of the inner ear deviate substantially from the condition reported as typical for Neanderthals and fall within the range of modern human variability.  (+info)

Australopithecus garhi: a new species of early hominid from Ethiopia. (7/2390)

The lack of an adequate hominid fossil record in eastern Africa between 2 and 3 million years ago (Ma) has hampered investigations of early hominid phylogeny. Discovery of 2.5 Ma hominid cranial and dental remains from the Hata beds of Ethiopia's Middle Awash allows recognition of a new species of Australopithecus. This species is descended from Australopithecus afarensis and is a candidate ancestor for early Homo. Contemporary postcranial remains feature a derived humanlike humeral/femoral ratio and an apelike upper arm-to-lower arm ratio.  (+info)

CT examination of the head of the Baikal seal (Phoca sibirica). (8/2390)

We carried out a computerised tomographic (CT) examination to elucidate the modifications in the head related to orbital enlargement in the Baikal seal. Transverse CT images showed that (1) the external frontal contours and the frontal sinuses are compressed medially and ventrally by the orbital enlargement; (2) the caudal part of the nasal cavity and nasopharynx are compacted ventrally; and (3) the cranial cavity is displaced caudally. The neurocranium is obviously separated from the facial part in the transverse plane at the caudal region of the orbit. The disposition of the mandible, zygomatic arch, temporal bone, and the masseter, temporal, digastric and pterygoid muscles is changed by the enlarged orbit in the 3-dimensional reorganisation of the head in this species. It is suggested that adaptation for the Lake Baikal environment primarily resulted in orbital enlargement, and that the altered orbital design may subsequently have influenced the form and function of the masticatory and respiratory system.  (+info)

The skull has a complex developmental history with bones developing both endochondrally and intramembranously. The skull arises from three cranial primordia. These primordia are the chondrocranium, the viscerocranium, and the dermatocranium. The chondrocranium is the cartilaginous base to the skull. This portion of the skull forms the initial supporting plates for the developing brain and the capsules associated with the special sensory structures of the ear, eye, and nose. These regions of the skull ossify endochonrally. The viscerocranium consists of the cartilaginous bars that originally arose as supports for the primitive gill structures. These gill bars become modified in the human skull to form the jaw anatomy, ear ossicles, and the hyoid bone. The largest contribution to the skull is from the dermatocranium. These are bones that form intramembranously in the embryonic mesenchyme. Much of the cranial vault and facial skeleton forms from the dermatocranium ...
Ubisofts long-in-the-works open-world pirate adventure Skull & Bones has been delayed again, seemingly pushing any potential new release date beyond March next year.. Skull & Bones was originally unveiled back at E3 2017, and was expected to launch on Xbox One, PS4, and PC some time in 2018. Last May, however, Ubisoft announced that it had made the decision to postpone its release to the 2019 financial year, making todays announcement the second public delay for the game.. Ubisoft broke news of the delay on Skull & Bones official Twitter page, writing that, Were going to batten down the hatches and push back on the games arrival - this is a challenging news for us all, but its whats needed to make Skull & Bones as awesome as it can be!.. ...
The most widely celebrated and mysterious crystal skull is the Mitchell-Hedges Skull, for at least two reasons. First, it is very similar in form to an actual human skull, even featuring a fitted removable jawbone. Most known crystal skulls are of a more stylized structure, often with unrealistic features and teeth that are simply etched onto a single skull piece. Second, it is impossible to say how the Mitchell-Hedges skull was constructed. From a technical standpoint, it appears to be an impossible object which todays most talented sculptors and engineers would be unable to duplicate. The discovery of the Mitchell-Hedges crystal skull, sometimes referred to as the Skull of Doom, is a controversial matter, and reads like a sci-fi action adventure film. The skull was made from a single, unusually large block of clear quartz crystal, and measured 5 inches high, 7 inches long, and 5 inches wide, weighing 11 pounds, 7 ounces. It closely corresponds in size to a small human cranium, with near ...
Raman spectral imaging provides the means to study spatially localized response to controlled external perturbations to tissue specimens with light microscopy resolution. We discuss use of heparin-acrylic microbeads soaked with the protein fibroblast growth factor-2 (FGF2). Microbeads containing FGF2 are placed in murine calvarial tissue and stimulate abnormally rapid mineralization. The tissue response simulated the effects of craniosynostosis, a birth defect occurring in 1 in 2400 live births. We describe Raman imaging measurements of the spatial distribution of apatitic mineral and matrix (predominantly type I collagen) from normal murine calvarial tissue and murine calvarial tissue modeling craniosynostosis. We also discuss spectroscopic evaluation of the state of the mineral induced by the FGF2 beads ...
Assembling the final pieces of the skeleton took a bit of time, mostly because of the number of bones there are and how to place all of them. There was also a setback that I didnt notice until using photographs of the Thoracosaurus display case to guide me in placing the bones. It turned out the 11th vertebrae had been skipped in scanning somehow. I had the 10th and the 12th, but not the 11th. I started to freak out a bit, but realized that about a year ago, Mark Petrovich had scanned half of the skeleton with an older, clunkier software. Luckily these scans are still backed up in multiple places. Mark and I then had to find these bones that were skipped and piece them together in PET (Polygon Editing Tool); which has a tendency to want to crash every time a user saves. I also want to note the importance of labeling and documenting the process of scanning. The students who were in charge of the scanning had a tendency to not adhere to strict naming conventions, which caused much confusion and ...

How many bones is the human skull made of? The skull or cranium is composed of eight cranial bones and fourteen facial bones, which are all fused together by sutures. The skull cranial bones protect the brain and they are: one frontal, two parietal, two sphenoid, two temporal, and one occipital bones. Dome of the skull is known as the skullcap and the lower part is called the base. The largest of the facial bones are the upper and lower jaws (maxilla and mandible). At the center of the base of the skull there is hole called foramen magnum, through which the spinal cord runs. The cranium turns freely on top of the vertebral column, which is made up of separate bones called vertebra. ...

The skull is the part of the skeleton that covers and protects the brain and other sense organs. The human skull is composed of 22 types of bones. These bones are separated into two categories, the bones the form the cranium and facial bones. The section of the brain that holds the brain is known as the cranium. The cranium is made up of eight flat bones that are connected. The cranium bones form the forehead and eye socket and the back of the skull. The facial bones include fourteen bones, the majority of them symmetrical to give the face symmetry. The facial bones include bones such as the maxilla, which is the upper jaw and the nasal bone. Joints known as sutures hold the bones together. At birth, the bones are not fully fused together, making the skull flexible. As a person grows, the bones of the cranium are fully fused together. ...
Humans grew bigger brains as the climate they lived in got cooler, according to researchers at the University at Albany, New York.. The researchers concluded that humans got brainier because they had to adapt to a more challenging environment. They base this assertion on a plot of cranial capacity of 109 fossilised human skulls against the corresponding paleontological record of two million years of changing climate.. As well as a relationship between a cooling earth and growing skulls, the researchers report that where the skulls were found matters, too, because the further you get from the Equator, the more varied the weather becomes.. Gordon G Gallup Jr, a professor of evolutionary psychology at the university, and co-author of the work along with graduate student Jessica Ash, commented: It became clear that seasonal variation in climate may also have been an important selective force behind the evolution of human cranial capacity. Specifically, we found that as the distance from the Equator ...
Transcriptional analysis of human cranial compartments with different embryonic origins[2] Previous investigations suggest that the embryonic origins of the calvarial tissues (neural crest or mesoderm) may account for the molecular mechanisms underlying sutural development. The aim of this study was to evaluate the differences in the gene expression of human cranial tissues and assess the presence of an expression signature reflecting their embryonic origins. Of six paired comparisons, frontal and parietal compartments (distinct tissue types of calvaria, either bone or intrasutural mesenchyme) had the most different gene expression profiles despite being composed of the same tissue type (bone). Transcriptional profiles of two groups of tissues, frontal and metopic compartments vs. parietal and sagittal compartments, suggest differences in proliferation, differentiation and extracellular matrix production. Our data suggest that in the second trimester of human foetal development, a gene ...
Supporting: 1, Mentioning: 36 - Large skull bone defects resulting from craniotomies due to cerebral insults, trauma or tumours create functional and aesthetic disturbances to the patient. The reconstruction of large osseous defects is still challenging. A treatment algorithm is presented based on the close interaction of radiologists, computer engineers and cranio-maxillofacial surgeons. From 2004 until today twelve consecutive patients have been operated on successfully according to this treatment plan. Titanium and polyetheretherketone (PEEK) were used to manufacture the implants. The treatment algorithm is proved to be reliable. No corrections had to be performed either to the skull bone or to the implant. Short operations and hospitalization periods are essential prerequisites for treatment success and justify the high expenses.
Its a bit tricky to assign purpose or consequence to morphological differences found in skeletal remians. Sometimes things are different due to genetic drift and random happen stance, and sometimes there is adaptive value to the difference. In the case of HLA differences theyre in a pretty good position to make judgements about adaptive value because HLA genes serve a reasonably well understood purpose. Theres quite a bit of debate about the purpose, or if there is a real purpose to the skull morphology differences in neanderthals (particularly as regards some of the nasal structures). Post cranial anatomy (Neck down) is virtually identical to moderns excepting the robustness of it.

def=the primitive cartilagionous skeletal structure of the fetal skull that grows to envelop the rapidly growing embyonic brain. In humans, the chondrocranium begins forming at 28 days from mesenchymal condensations and is fully formed between week 7 and 9 of fetal development. While the majority of the chondrocranium is succeeded by the bony skull in most higher vertebrates, some components do persist into adulthood.[1] In Cartilagious fishes and Agnathans, the chondrocranium persist throughout life.[2] Embryologically, the chondrocranium represent the basal cranial structure, and lay the base for the formation of the endocranium in higher vertebrates[WP].

Bored Panda reached out to Ashley Mason-Burns-Meerschaert, the director of education at Skeletons: Museum of Osteology, who told us more about these incredible bones. It turns out, the vertebrates with the most bones in their skulls are bony fish, which can have over 100 in their skulls.. Although skulls from different species might look similar, there will be slight differences. Ashley said that some species of shrews and rodents can only be identified by looking at dental variations under a microscope.. There is also some skull variation between individuals of the same species and also between males and females, which scientists refer to as sexual dimorphism.. Ashley said that animals skulls can change over time for various reasons, like becoming more adapted to the environment, changing due to animals diet, or because of injuries sustained over their lifetime.. ...
Paracas is a desert peninsula located within the Pisco Province in the Inca Region, on the south coast of Peru. It is here were Peruvian archaeologist, Julio Tello, made an amazing discovery in 1928 - a massive and elaborate graveyard containing tombs filled with the remains of individuals with the largest elongated skulls found anywhere in the world. These have come to be known as the Paracas skulls . In total, Tello found more than 300 of these elongated skulls, which are believed to date back around 3,000 years. A DNA analysis has now been conducted on one of the skulls and expert Brien Foerster has released preliminary information regarding these enigmatic skulls. It is well-known that most cases of skull elongation are the result of cranial deformation, head flattening, or head binding, in which the skull is intentionally deformed by applying force over a long period of time. It is usually achieved by binding the head between two pieces of wood, or binding in cloth. However, while ...

The brain skins called meninges (connective tissue of the central nervous system) are attached to the brain and the inside of the skull. Therefore if the sutures (gaps) between the skull bones are compressed, either through impact injury (such as a blow to the head), compression during the birth process (e.g. forceps application), or even vigorous dental procedures (affecting the maxilla - the purple bone you see in the skull) these meninges are impaired in their movement. This means the circulation around areas of the underlying brain tissue can be suboptimal ...

Posted on 02/17/2009 9:18:37 PM PST by XR7. The heirs of an Apache chieftain whose remains are rumored to be held inside Yales oldest secret society filed a lawsuit today demanding the return of their ancestors skull. Twenty descendants of the legendary Apache chieftain Geronimo are suing the federal government, the University and the society Skull & Bones in U.S. District Court for the District of Columbia to seek the return of his remains as well as punitive damages. One hundred years ago today, Geronimo died of pneumonia at Fort Sill, Okla., but the suit alleges members of the society exhumed his remains in 1918 or 1919 and transported them to the societys High Street tomb in New Haven. The group rumored to have stolen Geronimos skull, bones and other items from his gravesite is said to have included Prescott Bush, the father of former President George H. W. Bush 48 and grandfather to former President George W. Bush 68. To assure that all existing remains of Geronimo and funerary ...
The Tournaisian tetrapod Pederpes finneyae is described in detail, from the holotype and only specimen. The specimen derives from the Ballagan Formation, Tournaisian CM palynozone and is the earliest post-Devonian tetrapod known from articulated remains. It is preserved almost complete except for the tail, some skull regions and a few limb extremities. The animal resembles Whatcheeria deltae from the Vis´ean of Iowa, especially in the skull morphology, although the two differ in characters such as the lateral line expression, dermal ornament expression, proportions of the sub-orbital portion of the jugal and several other dermal skull characters. The postcranial skeleton of Pederpes shows several unique features, including the structure of the leading edges of the cleithrum and clavicle, the form of the rib flanges and a possible supernumerary digit on the manus. The humerus is also unusual in possessing a spike-like latissimus dorsi process, most like that of Baphetes. An investigation of the ...

The adult human skull consists of eight bones which form the cranium, or braincase, and 13 facial bones that support the eyes, nose, and jaws. There are also three small, paired ear ossicles-the malleus, incus, and stapes-within a cavity in the temporal bone. The total of 27 bones represents a large reduction in skull elements during the course of vertebrate evolution. The three components of the skull are the neurocranium, dermatocranium, and visceral cranium. See also Ear (vertebrate).. The brain and certain sense organs are protected by the neurocranium. All vertebrate neurocrania develop similarly, starting as ethmoid and basal cartilages beneath the brain, and as capsules partially enclosing the tissues that eventually form the olfactory, otic, and optic sense organs. Further development produces cartilaginous walls around the brain. Passages (foramina) through the cartilages are left open for cranial nerves and blood vessels. Endochondral ossification from four major centers follows in all ...

The skull reconstruction meme began in October 2019 when a photo of a medieval man made an appearance on Twitter. Skeletal remains of a man who was believed to have lived 600 years ago were found in Aberdeen. Researchers from the AOC Archaeology Group decided to reconstruct the skull to determine what the mans face looked like. When the final photo went on Twitter, the internet lost their minds on how weird-looking this medieval man was. And that, people, is how it all started. Now, the face of the medieval man pops up almost everywhere.. This meme was the inspiration behind this collection of photos showing how extraterrestrials would reconstruct common animals based on their skulls. We do feel sorry for the medieval man for becoming the center of ridicule in the modern age. But feel free to laugh at these skull reconstructions as these are funny versions of animals. A ferocious-looking predator in the eye of an extraterrestrial turns out to be just an adorable cat in reality. And a ...

A form of neuromodulation is conveyed from an external source to an interior of the skull to modulate neural activity. One or more apertures are formed through or partially through the skull to provide an interface for neuromodulation delivery. Parameters of one or more states of the brain may be sensed through an interface formed with one or more apertures extending all or part of the way through the skull. A device provides an interface between the exterior of the skull and the brain that includes a channel of a length sufficient to traverse the entire thickness of the skull or at least a part of the thickness of the skull. The channels may be configured for ion conduction of electrical signals, enabling DC or near DC stimulation of target neurons.

Then we have Manuscript B: the dreaded undergrad thesis. I have been working on this thing for a few years, and I really want to see it through, but its getting harder and harder to stay motivated. Its on something completely unrelated to what Im working on now (I looked at skull morphology in Centrosaurus to be exact), which makes it hard. Ive started working on it again, and I need to re-learn all the ceratopsian skull terminology. Met with my former supervisor and co-author last week, and he decided that I need to do a phylogenetic analysis, which Ive never done before outside of an assignment. Thanks to Andy Farke, I have a matrix to work with, and Im slowly combining a few different matrices. Im slowly learning how annoying it is when people use slightly different characters (like one paper uses one character as 0-75% and others use 0-80%. Why you have to be so difficult!), or switch around the character states. All in all, its not too bad, just time consuming ...
TY - JOUR. T1 - Regulation of DNA Synthesis in Chick Calvaria Cells by Factors from Bone Organ Culture. AU - Drivdahl, Rolf H.. AU - Puzas, J. Edward. AU - Howard, Guy A.. AU - Baylink, David J.. PY - 1981/11. Y1 - 1981/11. N2 - Embryonic chick bones growing in organ culture release a substance into the culture medium which stimulates bone formation in previously untreated bones. This conditioned medium also enhances proliferation of monolayer cultures of chick calvaria cells in serum-free medium. The active principle is nondialyzable, indicating a molecular weight greater than 12,000 daltons. Dialysis also separates the mitogenic activity from a low-molecuar-weight inhibitor. The amount of the mitogen found in conditioned medium increases as the rate of the bone resorption increases in response to treatment with parathyroid hormone or 1,25-dihydroxyvitamin D3. Maximal stimulation of DNA synthesis in calvaria cells is evident with conditioned medium obtained 3 to 5 days after treatment of bone ...

Brachycephalic dog breeds have a flat and wide skull shape. In dogs, it is the opposite to the skull shape of long nosed breeds such as the Greyhound which is called dolichocephalia. A brachycephlic skull therefore appears as though the skull has been severely compressed from front to back. In extreme cases it may appear that there is no nose present at all.
