If sleep increases your ability to resorb it, that would be a possible reason.

"It's a little-known fact that in addition to losing collagen and elastin as we age, we also resorb bone, so the whole scaffolding of the face is actually shrinking overtime," Dr. Engelman said.

It wasn't the procedure itself that had me screaming the place down but the part immediately afterward in which the technician kneaded my now slushy belly fat so that I could better resorb and eventually excrete as much of it as possible.

To prevent the bone from becoming unnecessarily thick, osteoclasts resorb the bone from the endosteal side.

Garden Snail, Cornu aspersum defecating. The anterior portion of the stomach opens into a coiled intestine, which helps to resorb water from the food, producing faecal pellets. The anus opens above the head.

Cysts that arise from tissue(s) that would normally develop into teeth are referred to as odontogenic cysts. Other cysts of the jaws are termed non- odontogenic cysts. Non-odontogenic cysts form from tissues other than those involved in tooth development, and consequently may contain structures such as epithelium from the nose. As the cyst grows from hydraulic pressure it causes the bone around it to resorb, and may cause movement of teeth or other vital structures such as nerves and blood vessels, or resorb the roots of teeth.

Although bone may appear superficially as a static tissue, it is actually very dynamic, undergoing constant remodeling throughout the life of the vertebrate organism. This occurs with the synchronized action of osteoclasts and osteoblasts, cells that resorb and deposit bone, respectively.

Osteoclasts in close proximity to the root surface will resorb the root surface cementum and underlying root dentin. This can vary in severity from evidence of microscopic pits in the root surface to complete devastation of the root surface. When there is insult leading to inflammation (trauma, bacteria, tooth whitening, orthodontic movement, periodontal treatment) in the root canal/s or beside the external surface of the root, cytokines are produced, the RANKL system is activated and osteoclasts are activated and resorb the root surface. If the insult is transient, resorption will stop and healing will occur, this is known as transient inflammatory resorption.

|
The growth in diameter of bones around the diaphysis occurs by deposition of bone beneath the periosteum. Osteoclasts in the interior cavity continue to resorb bone until its ultimate thickness is achieved, at which point the rate of formation on the outside and degradation from the inside is constant.

The length of an adult shell attains 16.5 mm, its diameter 6.5 mm. It is superficially similar to Benthofascis conorbioides, but it does not resorb the inner whorls. (Original description) The biconic, moderately thick shell has an ovately fusiform shape. Its surface is spirally furrowed, smooth and shining.

Transformation for overwintering larvae may take 13 months or more. Recent discoveries, such as overwintering, have management implications for this threatened species, particularly when aquatic habitats undergo modification. The larvae feed on other small invertebrates, including tadpoles. When their pond dries, they resorb their gills, develop lungs, and then the metamorphs leave the pond in search of a burrow.

|
PTHrP is critical in intraosseous phase of tooth eruption where it acts as a signalling molecule to stimulate local bone resorption. Without PTHrP, the bony crypt surrounding the tooth follicle will not resorb, and therefore the tooth will not erupt. In the context of tooth eruption, PTHrP is secreted by the cells of the reduced enamel epithelium.

In Anagrus, depending on the species, lifespan ranges from three to 11 days. Each fertilized (or parthenogenic) female can lay a maximum of about 100 eggs. Access to food can prolong lifespans and increase fecundity. In Gonatocerus, if hosts are not found females can resorb eggs, retaining energy to live longer and increase the chance of finding a host.

Edentulous jaw ridges tend to resorb progressively over the years, especially the alveolar ridge of the lower jaw. Mucosa reacts to being chronically rubbed by the dentures. Poorly fitting dentures hasten both of those processes compared to the rates with well-fitting dentures. Poor fitting dentures may also lead to the development of conditions such as epulis fissuratum.

Larvae hatch after two to five weeks, depending on temperature. As in all salamanders and newts, forelimbs develop first, followed later by the back legs. Unlike smaller newts, crested newt larvae are mostly nektonic, swimming freely in the water column. Just before the transition to land, the larvae resorb their external gills; they can at this stage reach a size of .

The tissues in the mediastinum will slowly resorb the air in the cavity so most pneumomediastinums are treated conservatively. Breathing high flow oxygen will increase the absorption of the air. If the air is under pressure and compressing the heart, a needle may be inserted into the cavity, releasing the air. Surgery may be needed to repair the hole in the trachea, esophagus or bowel.

Non-peptide substances were known to be able to solve the problems of poor pharmacokinetic properties and low specificity. This led to the design of small molecules, non-peptide inhibitors, which were very potent and specific of human renin. However, caused by their chemical structure even third-generation renin inhibitors are difficult to resorb by the human body and their oral bioavailability is often below 2%.

The cause of the disease is understood to be malfunctioning osteoclasts and their inability to resorb bone. Although human osteopetrosis is a heterogeneous disorder encompassing different molecular lesions and a range of clinical features, all forms share a single pathogenic nexus in the osteoclast. The exact molecular defects or location of the mutations taking place are unknown. Osteopetrosis was first described in 1903, by German radiologist Albers-Schönberg.

These terms can also be used to refer to the clinical sense of the words, as relative crown and relative root, by describing how much tooth remains surrounded by bone. As the inflammation associated with periodontal disease causes the bone to resorb and disappear, revealing more of the root structure, the effective crown height in relation to the effective root height is reduced and the prognosis shifts from favorable to unfavorable.

Topical antibiotic eye drops or ointment (e.g., chloramphenicol or fusidic acid) are sometimes used for the initial acute infection, but are otherwise of little value in treating a chalazion. Chalazia will often disappear without further treatment within a few months, and virtually all will resorb within two years. Healing can be facilitated by applying a warm compress to the affected eye for approximately 15 minutes 4 times per day.

During metamorphism, sulfur and nickel within the olivine lattice are reconstituted into metamorphic sulfide minerals, chiefly millerite, during serpentinization and talc carbonate alteration. When metamorphic olivine is produced, the propensity for this mineral to resorb sulfur, and for the sulfur to be removed via the concomitant loss of volatiles from the serpentinite, tends to lower sulfur fugacity. In this environment, nickel sulfide mineralogy converts to the lowest-sulfur state available, which is heazlewoodite.

The authors further proposed a modification to the classification of Bouchet & Rocroi (2005) for ten additional Conoidea families (which do not resorb their inner walls) which included turrids which had been placed in the Conidae by Taylor, et al. in 1993.Taylor, J.D, Kantor, Yu. I. & Sysoev, A.V. (1993) Foregut anatomy, feeding mechanisms, relationships and classification of the Conoidea (=Toxoglossa)(Gastropoda).

In its mildest form it is just a localized tissue swelling and soreness whereas in severe forms the swelling is slightly larger even sometimes creating trismus (difficulty opening the mouth). Occasionally, an impacted tooth causes sufficient pressure on the roots of adjacent teeth causing it to resorb. An impacted tooth occupies space that is usually filled with bone. This weakens that area of bone and renders the jaw more susceptible to fracture.

Some females abort or resorb their own young while they are still in development after a new male takes over; this is known as the Bruce effect. This may prevent their young from being killed after birth, saving the mother wasted time and energy. However, this strategy also benefits the new male. In mice this can occur by the proximate mechanism of the female smelling the odor of the new male's urine.

In 2009 John K. Tucker and Manuel J. Tenorio proposed a classification system for the cone shells and their allies (which resorb their inner walls during growth) based upon a cladistical analysis of anatomical characters including the radular tooth, the morphology (i.e. shell characters), as well as an analysis of prior molecular phylogeny studies, all of which were used to construct phylogenetic trees.Tucker J.K. & Tenorio M.J.

Thus bone remodeling is not just occasional "repair of bone damage" but rather an active, continual process that is always happening in a healthy body. Subsequent to appropriate signaling, osteoclasts move to resorb the surface of the bone, followed by deposition of bone by osteoblasts. Together, the cells that are responsible for bone remodeling are known as the basic multicellular unit (BMU), and the temporal duration (i.e. lifespan) of the BMU is referred to as the bone remodeling period.

After this period, they begin to ingest small invertebrates, and actively forage about ten days after hatching. As in all salamanders and newts, forelimbs—already present as stumps at hatching—develop first, followed later by the back legs. Unlike smaller newts, Triturus larvae are mostly nektonic, swimming freely in the water column. Just before the transition to land, the larvae resorb their external gills; they can at this stage reach a size of in the larger species.

Osteocyte apoptosis is thought to be related to decreased mechanotransduction, which possibly leads to the development of osteoporosis. Apoptotic osteocytes release apoptotic bodies expressing RANKL to recruit osteoclasts. Mechanical loading increases osteocyte viability in vitro, and contributes to solute transport through the lacuno-canalicular system in bone, which enhances oxygen and nutrient exchange and diffusion to osteocytes. Skeletal unloading has been shown to induce osteocyte hypoxia in vivo, this is when osteocytes undergo apoptosis and recruit osteoclasts to resorb bone.

Osteoclast-associated immunoglobulin-like receptor is a protein that in humans is encoded by the OSCAR gene. Osteoclasts are multinucleated cells that resorb bone and are essential for bone homeostasis. This gene encodes an osteoclast- associated receptor (OSCAR), which is a member of the leukocyte receptor complex (LRC) protein family that plays critical roles in the regulation of both innate and adaptive immune responses. Different from the other LRC members, OSCAR expression is detected specifically in preosteoclasts or mature osteoclasts.

Breeding schedules for rabbits vary by individual operation. Prior to the development of modern balanced rabbit rations, rabbit breeding was limited by the nutrition available to the doe. Without adequate calories and protein, the doe would either not be fertile, would abort or resorb the foetuses during pregnancy, or would deliver small numbers of weak kits. Under these conditions, a doe would be re-bred only after weaning her last litter when the kits reached the age of two months.

Mammals share the same reproductive system, including the regulatory hypothalamic system that produces gonadotropin-releasing hormone in pulses, the pituitary gland that secretes follicle-stimulating hormone and luteinizing hormone, and the ovary itself that releases sex hormones, including estrogens and progesterone. However, species vary significantly in the detailed functioning. One difference is that animals that have estrous cycles resorb the endometrium if conception does not occur during that cycle. Animals that have menstrual cycles shed the endometrium through menstruation instead.

It has been shown that epithelial sodium channel ENaC that allows the flow of Na+ ions into the cell is localized on stereocilia. Because sperm are initially non-motile as they leave the seminiferous tubules, large volumes of fluid are secreted to propel them to the epididymis. The core function of the stereocilia is to resorb 90% of this fluid as the spermatozoa start to become motile. This absorption creates a fluid current that moves the immobile sperm from the seminiferous tubules to the epididymis.

Cortical bone is known to resorb slower than the medullary bone. Therefore, cortical anchorage is used in orthodontics to allow for slower movement of teeth, especially molars in the posterior dentition. A clinician may produce a movement which allows the buccal roots of the permanent molars to move buccally (outside), eventually contacting the cortical bone. It is claimed that by using cortical bone against posterior teeth, mesial movement of posterior teeth can be prevented which helps in anchoring the posterior teeth in the back of the jaw.

The presence of a hard, calcified exoskeleton means that the crustacean has to molt and shed the exoskeleton as its body size increases. This links the calcification process to the molting cycles, making a regular source of calcium and carbonate ions crucial. The crustacean is the only phylum of animals that can resorb calcified structures, and will reabsorb minerals from the old shell and incorporate them into the new shell. Various body parts of the crustacean will have a different mineral content, varying the hardness at these locations with the harder areas being generally stronger.

Collagen membranes are of either type I or II collagen from cows or pigs. They are often cross-linked and take between four and forty weeks to resorb, depending on the type. Collagen absorbable barrier membranes do not require surgical removal, inhibit migration of epithelial cells, promote the attachment of new connective tissue, are not strongly antigenic and prevent blood loss by promoting platelet aggregation leading to early clot formation and wound stabilization. Collagen membranes may also facilitate primary wound closure via fibroblast chemotactic properties, even after membrane exposure.

It is estimated that these deposits may resorb after ten years of following a gluten-free diet. Moreover, it is suggested that this condition is closely linked to genetics. This theory is based on the arguments that individuals with a family history of gluten sensitivity who still consume foods containing gluten are more likely to develop the condition as a result of the formation of antibodies to gluten. These antibodies cross-react with eTG, and IgA/eTG complexes deposit within the papillary dermis to cause the lesions of dermatitis herpetiformis.

NEDD9 also regulates Aurora-A activation at the basal body of cilia as cells resorb cilia during early G1. Cilia are small organelles that protrude from the surface of adherent cells that are the obligate site of action for proteins such as Hedgehog, and the polycystins: by influencing ciliary stability, NEDD9 is positioned to affect these signaling systems. Interaction of NEDD9 with Aurora A kinase may also play a role in tumor invasion. NEDD9 binds to and regulates acetylation of cortactin (CTTN) in an Aurora A kinase (AURKA)/HDAC6–dependent manner.

It can shed their leaves drought- deciduous species can adjust to only discharge nutrient after drought relief for canopy reconstruction and leave growth. Deciduous plant species can resorb Nitrogen, Phosphorus and Potassium which are the fundamental elements required by plants. This can additionally prevent significant impacts due to nutrient losses caused by leaf abscission. During the period after abscission had occurred, reserves of twig nitrogen in drought-deciduous species changes accordingly with season or external stress, whereas evergreen species had a constant twig nitrogen level throughout the year.

The action of osteoblasts and osteoclasts are controlled by a number of chemical enzymes that either promote or inhibit the activity of the bone remodeling cells, controlling the rate at which bone is made, destroyed, or changed in shape. The cells also use paracrine signalling to control the activity of each other. For example, the rate at which osteoclasts resorb bone is inhibited by calcitonin and osteoprotegerin. Calcitonin is produced by parafollicular cells in the thyroid gland, and can bind to receptors on osteoclasts to directly inhibit osteoclast activity.

This channel is primarily responsible for controlling the movement of halide anions from inside to outside of the cell; however, in the sweat ducts, it facilitates the movement of chloride from the sweat duct into the cytoplasm. When the CFTR protein does not resorb ions in sweat ducts, chloride and thiocyanate released from sweat glands are trapped inside the ducts and pumped to the skin. Additionally hypothiocyanite, OSCN, cannot be produced by the immune defense system. Because chloride is negatively charged, this modifies the electrical potential inside and outside the cell that normally causes cations to cross into the cell.

Tucker and Tenorio's 2009 classification system for the cone shells and their allies (which resorb their inner walls during growth) was based on a cladistical analysis of anatomical characters, including the radular tooth, the morphology (i.e. shell characters), as well as an analysis of prior molecular phylogeny studies, all of which were used to construct phylogenetic trees. In their phylogeny, Tucker and Tenorio noted the close relationship of the cone species within the various clades, corresponding to their proposed families and genera; this also corresponded to the results of prior molecular studies by Puillandre et al. and others.

Magmatic olivine generally has up to ~4000 ppm Ni and up to 2500 ppm S within the crystal lattice, as contaminants and substituting for other transition metals with similar ionic radii (Fe2+ and Mn2+). Millerite structure During metamorphism, sulfur and nickel within the olivine lattice are reconstituted into metamorphic sulfide minerals, chiefly millerite, during serpentinization and talc carbonate alteration. When metamorphic olivine is produced, the propensity for this mineral to resorb sulfur, and for the sulfur to be removed via the concomitant loss of volatiles from the serpentinite, tends to lower sulfur fugacity. This forms disseminated needle like millerite crystals dispersed throughout the rock mass.

Lipoinjection contouring and augmentation with the patient's own body fat avoids the possibility of tissue rejection, and is physically less invasive than buttocks-implant surgery. Therefore, depending upon the health of the patient, the convalescence period allows him or her to resume daily, normal- life activities at 2-days post-operative, and the full spectrum of physical activity at 2-weeks post-operative. Furthermore, the liposuction harvesting of the patient's excess body fat improves the aesthetic appearance of the body fat donor-sites. Nonetheless, physiologically, the human body's normal, health-management chemistry does resorb (break down and eliminate) some of the injected adipose-fat tissue, and so might diminish the augmentation.

Hollande campaigning François Hollande, the candidate of the Socialist Party and the Radical Party of the Left, topped the opinion polls throughout the campaign. He emphasised his promise to be a "normal" president, in contrast to Nicolas Sarkozy's sometimes controversial presidential style. He aimed to resorb France's national debt by 2017, notably by cancelling tax cuts for the wealthy and tax exemptions introduced by President Sarkozy. Income tax would be raised to 75% for incomes beyond one million euros; the retirement age would be brought back to 60 (with a full pension) for persons who have worked 42 years; 60 000 jobs cut by Nicolas Sarkozy in public education would be recreated.

This is an essential principle in the interpretation of clinical regenerative studies. For instance, instrumentation of dentin cylinders followed by irrigation with 5.25% NaOCl and extensive washing results in a dentin surface that promotes differentiation of cells into clastic-like cells which resorb dentin. On the contrary, if the dentin cylinders are irrigated with 17% EDTA either alone, or following NaOCl treatment, a dentin surface that promotes cell differentiation into cells expressing an appropriate marker for a mineralizing phenotype, such as the dentin sialoprotein is produced. Therefore, the selection of irrigants as well as their sequence may play essential roles in conditioning dentin into a surface capable of supporting differentiation of a desired cell phenotype.

Bouchett (2008), Starting to unravel the toxoglossan knot: molecular phylogeny of the "turrid" (Neogastropoda: Conoidea), Molecular Phylogenetics and Evolution 47:1122-1134. This 2009 proposed classification system also outlined the taxonomy for the other clades of Conoidean gastropods (that do not resorb their inner walls), also based upon morphological, anatomical, and molecular studies, and removes the turrid snails (which are a distinct large and diverse group) from the cone snails and creates a number of new families. For Tucker and Tenorio’s classification system for the cone shells and their allies (and the other clades of Conoidean gastropods) see Tucker & Tenorio cone snail taxonomy 2009.

The RANK/RANKL/OPG axis is a critical pathway in maintaining the symbiosis between bone resorption by osteoclasts and bone formation by osteoblasts. RANKL is released by osteoblast lineage cells and binds to receptor RANK on the surface of osteoclast progenitor cells RANK- RANKL binding activates the nuclear factor kappa B (NF-κB) pathway resulting in the upregulation of the transcription factor nuclear factor of activated T-cells cytoplasmic 1 (NFATc1). NFATc1 is a master regulator for the expression of essential cytokines during the differentiation of osteoclast precursor cells into mature osteoclasts, known as osteoclastogenesis. Mature osteoclasts then bind to bone through tight junctions and release digestive enzymes to resorb the old bone.

In contrast to HRS, however, pre-renal kidney failure usually responds to treatment with intravenous fluids, resulting in reduction in serum creatinine and increased excretion of sodium. Acute tubular necrosis (ATN) involves damage to the tubules of the kidney, and can be a complication in individuals with cirrhosis, because of exposure to toxic medications or the development of decreased blood pressure. Because of the damage to the tubules, ATN affected kidneys usually are unable to maximally resorb sodium from the urine. As a result, ATN can be distinguished from HRS on the basis of laboratory testing, as individuals with ATN will have urine sodium measurements that are much higher than in HRS; however, this may not always be the case in cirrhotics.

When trabecular bone volume decreases, its original plate-and-rod structure is disturbed; plate-like structures are converted to rod-like structures, and pre-existing rod-like structures thin until they disconnect and resorb into the body. Changes in trabecular bone are typically gender-specific, with the most notable differences in bone mass and trabecular microstructure occurring within the age range for menopause. Trabeculae degradation over time causes a decrease in bone strength that is disproportionately large in comparison to volume of trabecular bone loss, leaving the remaining bone vulnerable to fracture. With osteoporosis there are often also symptoms of osteoarthritis, which occurs when cartilage in joints is under excessive stress and degrades over time, causing stiffness, pain, and loss of movement.

A tightening of fishing regulations for wild Murray cod, as referred to above, and a switch by fishermen to a largely catch and release approach for wild Murray cod would alleviate this problem. Recognising these issues, in late 2014 the New South Wales and Victorian fishery departments amended their regulations so that a slot limit of 55 to 75 cm now applies in these states. (I.e. Only Murray cod between 55 and 75 cm may be taken; those above and below this size range or "slot" must be released.) This measure should have positive effects for the Murray cod population by protecting and increasing the proportion of large breeding Murray cod. Another issue is that Murray cod caught and released in winter, while developing their eggs, or in spring prior to spawning, resorb their eggs and do not spawn.
