Transplantation of osteoblast-like cells to the distracted callus in rabbits. (1/181)

We carried out limb lengthening in rabbits and then transplanted osteoblast-like cells derived from the tibial periosteum to the centres of distracted callus immediately after distraction had been terminated. Two weeks later the transaxial area ratio at the centre of the distracted callus and the bone mineral density (BMD) were significantly higher in the transplanted group, by 21% and 42%, respectively, than in the non-injected group or the group injected with physiological saline (p < 0.05). Callus BMD as a percentage of density in uninvolved bone was also significantly higher in the transplanted group (p < 0.05) than in the other two groups, by 27% and 20% in the second and fourth weeks, respectively (p < 0.05). Mechanically, the callus in the transplanted group tended to be stronger as shown by the three-point bending test although the difference in fracture strength was not statistically significant. Our results show that transplantation of osteoblast-like cells promotes maturity of the distracted callus as observed at the second and fourth weeks after lengthening. The method appears promising as a means of shortening the consolidation period of callus distraction and decreasing complications during limb lengthening with an external fixator.  (+info)

Percutaneous autologous bone marrow grafting on the site of tibial delayed union. (2/181)

Six months after injury, 150 mL of autogenous bone marrow was applied percutaneously at the site of delayed union to stimulate the healing of a tibial delayed union fracture in a 44 year-old man. Five months following the procedure, the fracture gaps and bone defects were completely filled with callus, the external fixator was removed, and the patient started using normal leg loading.  (+info)

Transforming growth factor-beta1 modulates the expression of vascular endothelial growth factor by osteoblasts. (4/181)

Angiogenesis is essential to both normal and pathological bone physiology. Vascular endothelial growth factor (VEGF) has been implicated in angiogenesis, whereas transforming growth factor-beta1 (TGF-beta1) modulates bone differentiation, matrix formation, and cytokine expression. The purpose of this study was to investigate the relationship between TGF-beta1 and VEGF expression in osteoblasts and osteoblast-like cells. Northern blot analysis revealed an early peak of VEGF mRNA (6-fold at 3 h) in fetal rat calvarial cells and MC3T3-E1 osteoblast-like cells after stimulation with TGF-beta1 (2.5 ng/ml). The stability of VEGF mRNA in MC3T3-E1 cells was not increased after TGF-beta1 treatment. Actinomycin D inhibited the TGF-beta1-induced peak in VEGF mRNA, whereas cycloheximide did not. Blockade of TGF-beta1 signal transduction via a dominant-negative receptor II adenovirus significantly decreased TGF-beta1 induction of VEGF mRNA. Additionally, TGF-beta1 induced a dose-dependent increase in VEGF protein expression by MC3T3-E1 cells (P < 0.01). Dexamethasone similarly inhibited VEGF protein expression. Both TGF-beta1 mRNA and VEGF mRNA were concurrently present in rat membranous bone, and both followed similar patterns of expression during rat mandibular fracture healing (mRNA and protein). In summary, TGF-beta1-induced VEGF expression by osteoblasts and osteoblast-like cells is a dose-dependent event that may be intimately related to bone development and fracture healing.  (+info)

Subchondral insufficiency fracture of the femoral head: a differential diagnosis in acute onset of coxarthrosis in the elderly. (5/181)

OBJECTIVE: To document subchondral insufficiency fracture (SIF) of the femoral head and investigate its frequency. METHODS: The study was based on a retrospective review of 464 removed femoral heads (from 419 patients) with both radiologic and histologic evidence of subchondral collapse. Gross photographs, specimen radiographs, and histologic sections were reevaluated in all cases. Available clinical notes and imaging studies were also reviewed. RESULTS: Ten cases previously diagnosed as osteonecrosis were reinterpreted as SIF on a histopathologic basis. All of these patients were women over 65 years old (average age 75) with osteopenia. The initial symptom was acute onset of hip pain. Radiologically, a subchondral collapse, mainly in the superolateral segment of the femoral head, was noted. Magnetic resonance imaging, available in 3 cases, showed diffuse low intensity on T1-weighted images and high intensity on T2-weighted or fat-suppressed images. Bone scintigraphy, available in 4 cases, showed increased uptake in the femoral head. Histopathologically, a 1.0-2.5-cm long linear whitish gray zone, comprising fracture callus and granulation tissue, was found beneath the subchondral bone end plate. There was no evidence of antecedent osteonecrosis. CONCLUSION: The results of this study indicate that SIF should be included in the differential diagnosis of acute onset of coxarthrosis in the elderly.  (+info)

Growth factors in distraction osteogenesis. Immuno-histological pattern of TGF-beta1 and IGF-I in human callus induced by distraction osteogenesis. (6/181)

Although growth factors have been demonstrated during bone healing, their presence has not yet been confirmed in callus distraction. Therefore, in 3 patients we searched for cytokines during callus distraction. Bone biopsies were immuno-histochemically stained for TGF-beta1, IGF-I, TGF-beta type II receptor, IGF receptor, and proliferating cell nuclear antigen (PCNA). Histologically we found immature woven bone in the middle of the callus zone and increasing calcification and lamellar bone in the re-modelling zone. Osteoblasts and fibroblast-like cells in the middle zone, and osteoblasts in all zones stained for TGF-beta and its receptor. The number of positive staining cells related to proliferous activity as assessed both by PCNA, and by bone density in radiographs. IGF-I could be detected everywhere. In conclusion, growth factors are present in bone formation and in areas of re-modelling during callotasis. Their relation to proliferous activity and radiographic density supports their involvement in osteogenesis.  (+info)

Parathyroid hormone (1-34) increases the density of rat cancellous bone in a bone chamber. A dose-response study. (7/181)

Intermittent treatment with parathyroid hormone I(PTH) has an anabolic effect on both intact cancellous and cortical bone. Very little is known about the effect of the administration of PTH on the healing of fractures or the incorporation of orthopaedic implants. We have investigated the spontaneous ingrowth of callus and the formation of bone in a titanium chamber implanted at the medioproximal aspect of the tibial metaphysis of the rat. Four groups of ten male rats weighing approximately 350 g were injected with human PTH (1-34) in a dosage of 0, 15, 60 or 240 microg/kg/day, respectively, for 42 days from the day of implantation of the chamber. During the observation period the chamber became only partly filled with callus and bone and no difference in ingrowth distance into the chamber was found between the groups. The cancellous density was increased by 90%, 132% and 173% in the groups given PTH in a dosage of 15, 60 or 240 microg/kg/day, respectively. There was a linear correlation between bone density and the log PTH doses (r 2= 0.6). Our findings suggest that treatment with PTH may have a potential for enhancement of the incorporation of orthopaedic implants as well as a beneficial effect on the healing of fractures when it is given in low dosages.  (+info)

The influence of stiffness of the fixator on maturation of callus after segmental transport. (8/181)

The treatment of large bony defects by callus distraction is well accepted, but the duration of treatment is long and the rate of complications increases accordingly. We have examined the effect of the stiffness of the axial fixator on reducing the time for maturation of callus. We created a mid-diaphyseal defect of 15 mm in the metatarsal bone in sheep and stabilised it with a ring fixator. After four days a bony segment was transported for 16 days at 1 mm per day. After 64 days the animals were divided into four groups, three with axial interfragmentary movement (IFM) of 0.5, 1.2 and 3.0 mm, respectively, and a control group. The 3.0 mm IFM group had the smallest bone density (p = 0.001) and area of callus and the largest IFM after 12 weeks; it also had typical clinical signs of hypertrophic nonunion. The most rapid stiffening of the callus was in the 0.5 mm group which had the smallest IFM (p = 0.04) after 12 weeks and radiological signs of bridging of the defect. These results indicate that suitable dynamic axial stimulation can enhance maturation of distraction callus when the initial amplitude is small, but that a large IFM can lead to delayed union.  (+info)

1. Evaluation of all characters has to be carried out by at least two members of the staff who have to agree on the characters observed.. 2. Evaluation of all characters should be performed with each culture once a year.. 3. Evaluation should start with the observation of growth. Evaluation of all other characters of one cell line has to be finished within one month after entering the code number for growth into the computer. 4. For the evaluation of growth the increase in callus volume is observed over two growth cycles.. The following code numbers are used to describe growth: no growth = code no. 0; 30 - 50 % increase of cell material (callus volume) = code no. 1; 50 - 100 % increase of cell material (callus volume) = code no. 2, 100 % increase of cell material (callus volume) or more = code no. 3. 5. Consistency of the callus should be judged shortly after or ideally during regular transfer. The following code numbers are used to describe the consistency of callus: very soft = code no. -2; ...

Little is known about the molecular composition and mineral structure of the newly formed tissue in the callus. The aim was to evaluate the feasibility of small angle x-ray scattering (SAXS) to assess mineral structure of callus and cortical bone and if it could provide complementary information with the compositional analyses from Fourier transform infrared (FTIR) microspectroscopy. Femurs of 12 male Sprague-Dawley rats at 9 weeks of age were fractured and fixed with an intramedullary 1.1 mm K-wire. Fractures were treated with the combinations of bone morphogenetic protein-7 and/or zoledronate. Rats were sacrificed after 6 weeks and both femurs were prepared for FTIR and SAXS analysis. Significant differences were found in the molecular composition and mineral structure between the fracture callus, fracture cortex, and control cortex. The degree of ...
Building Good Calluses: To build calluses you have to use your hands. Some of us with desk jobs do not build calluses needed for riding - the keyboard just doesnt cut it. The top layer of skin, the epidermis is made of dead skin cells that come from the dermis below. The thicker the layer, the less sensitive it is. Calluses are thick layers that dont form blisters but are still soft and flexible enough not to crack, restrain movement or interfere with sensation. Calluses require friction and movement to trigger growth, yet lotion is required to keep hands moist and healthy as well. To keep the calluses from overgrowing - as they tend to crack - one of the only solutions is to peel them off exposing new skin. Calluses are built up from friction and/or pressure; its essentially the buildup of keratin-dense skin over the existing top layer of skin (this keratin is more nail-like in its structure than hair-like.) Pressure is how string instrument players build callus over fingertips and how ...
Normally, a callus will form on any part of the skin exposed to excess friction over a long period of time. For example, people often develop calluses on the middle finger of their dominant hand due to writing with a pen or pencil. Another cause is from playing string instruments like the guitar or the violin; calluses will develop on the four fingers of the hand used in holding the strings down to the fingerboard, and sometimes on the fingers of the hand used for pizzicato or strumming. Weightlifters commonly experience callus on the upper-palm area due to repeated friction. Calluses are also very common on the fingers of rock climbers on almost all of their fingers. There are many activities that can result in the formation of a callus, which may even be viewed as a badge of experience and commitment to the activity. Activities that are notorious for causing calluses include (but are not limited to) construction work, many sports, wood carving, playing musical instruments, use of a chefs ...
The biological activity of 24R,25-dihydroxyvitamin D3 [24R,25(OH)2D3] remains controversial, but it has been suggested that it contributes to fracture healing. Cyp24a1-/- mice, synthesizing no 24R,25(OH)2D3, show suboptimal endochondral ossification during fracture repair, with smaller callus and reduced stiffness. These defects were corrected by 24R,25(OH)2D3 treatment, but not by 1,25-dihydroxyvitamin D3. Microarrays with Cyp24a1-/- callus mRNA identified FAM57B2 as a mediator of the 24R,25(OH)2D3 effect. FAM57B2 produced lactosylceramide (LacCer) upon specific binding of 24R,25(OH)2D3. Fam57b inactivation in chondrocytes (Col2-Cre Fam57bfl/fl) phenocopied the callus formation defect of Cyp24a1-/- mice. LacCer or 24R,25(OH)2D3 injections restored callus volume, stiffness, and mineralized cartilage area in Cyp24a1-null mice, but only LacCer rescued Col2-Cre Fam57bfl/fl mice. Gene expression in callus tissue suggested that the 24R,25(OH)2D3/FAM57B2 cascade affects cartilage maturation. We ...

Calluses and dry skin on the soles of your feet, heels and toes is a challenge. Exfoliating is ideal to remove dead skin, but calluses are a different challenge. Regular pedicures can help manage calluses, however this is not recommended for individuals with diabetes. If you have diabetes and you have rough dry feet, visit a podiatrist to have calluses removed. A great at home callus removal practice includes soaking your feet in 8 cups of water with 2 cups of apple cider vinegar. Allow feet to soak for 15-20 minutes and then pat dry. Use a pumice stone or pedicure stone to remove calluses. Never cut them with scissors, or shave them, as this can lead to infections and pain.. ...
Biswas, G.C.G.; Zapata, F.J., 1990: Callus formation and plant regeneration from protoplasts derived from suspension culture of rice (Oryza sativa L. cv. 'Taipei 177')
A callus (tyloma) is a thickening of the skin that occurs in response to excessive, repeated shear or friction forces, commonly due to constant rubbing of the skin. Calluses are similar to corns, but calluses occur when abnormal forces are exerted over a larger area. Certain deformities of the feet, such as crookedness of the toes, may predispose to the development of calluses. Calluses may cause pain, typically a burning sensation. Excessive weight bearing and certain types of shoes are often contributing factors.. ...
the persons toes are commonly soft.. Corn may be painful because the thickened skin transfers pressure to the underlying bones. Calluses may appear anywhere on the persons body, but mostly progress over bony spots on the elbows, feet, hands or other regions that take repeated abuse or wear. Usually, corns and calluses are easy to identify. In some cases, corn is confused with a wart, that also contains a thickening keratitis layer. However, corn is more sensitive to direct pressure inward or downward against the bones, while a wart is extremely sensitive when squeezed from the sides.. Calluses and corns are more difficult to treat than to prevent. Calluses can be prevented by removing irritation cause or if it is not possible, by wearing pads, gloves or other protective subjects. Many pharmacies sell suitable ring shapes and protective pads for such a purpose. Corns can go away by wearing better-fitting shoes, if the corn results from ill-fitting shoes.. Corns may be more quickly removed by ...

UNDERfoot. Calluses on our feet can be more than just unsightly. Depending on their size and location, they can also be painful. Summer weather, certain shoes, and walking barefoot can cause or worsen calluses. If left untreated, calluses can deform the foot, contribute to infections and cause poor wound healing. Care must be taken when trying to minimize or remove calluses, for it is easy to make them worse.. Ironically, the more aggressively you try to remove a callus, the more damage you cause to the foot. Do not use sharp tools or any kind of razorblade to scrape off calluses. Instead, soak your feet in warm, soapy water for 10 minutes; dry completely; gently exfoliate your calluses with professional smoother; then seal the job with a foot cream or your favorite body lotion.

Among the various organs of inflorescences, systemically infected with Albugo candida explants from hypertrophied peduncles and thickened terminal leaves proved suitable for the production of dua cultures of the biotroph and its host, success with the former being better than with the latter. Dual cultures were also established from ovaries, but poorly. Infected callus grew faster than its healthy counterpart. Leaf and sten pieces with rust pustules did not form callus. The dual culture showed abundant coenocytic intercellular mycelium with spherical haustoria within host cells. Infected callus maintained at 15 and 20 °C for 20 to 30 d showed only sporangial chains that remained confined within the callus tissue, whereas callus maintained at 25 and 30 °C contained both sporangia and oospores, like those of A. candida found in naturally infected tissues. The pathoge could
Calluses, or thickened skin, result from on-going friction or pressure on a particular area of skin. On the foot, calluses (hyperkeratosis) commonly occur on areas subjected to pressure and impact: the heels, balls of the foot, and the big toe. Calluses cause irritation and pain as the thickened skin continues to be exposed to pressure or rub against footwear. Although the skin is affected, the bone beneath it is what actually causes the problem. Corns and blisters can also result from friction and pressure on the feet and toes.. Some calluses are painful and sore; the nerves are inflamed and fluid-filled sacs form underneath the callused area. Orthotic inserts and properly fitting footwear can prevent and alleviate calluses. Cortisone injections can provide rapid pain relief of inflammation and pain. For cases of heel callus formation resulting from a metatarsal bone deformity, surgery may be necessary to correct the bone and lessen the pressure.. To reduce calluses, soak affected feet in warm, ...
The formation of calluses is caused by an accumulation of dead skin cells that harden and thicken over an area of the foot. This callus formation isthe bodys defense mechanism to protect the foot against excessive pressure and friction. Calluses are normally found on the ball-of-the-foot, the heel, and/or the inside of the big toe.. Some calluses have a deep seated core known as a nucleation. This particular type of callus can be especially painful to pressure. This condition is often referred to as Intractable Plantar Keratosis.. Cause ...

Plant lipid metabolism pathways have been extensively studied as increasing plant oil yields is one important goal among researchers. However, the gene expression pattern of lipid metabolism regulating pathways especially in wound-induced callus of Arabidopsis thaliana is still unknown. The use of artificial microRNA retinoblastoma-related (amiRBR) strain allowed for the study of reduced RBR expression effects on lipid accumulation. Although the lipid contents in hormone-induced callus were possibly lower than leaves in wild-type (WT) A. thaliana, wound-induced callus was used to eliminate genetic interferences. Lipid content comparisons on 7-, 14- and 21-day old leaf and callus showed possibly higher lipid content in WT callus, although amiRBR callus contained possibly higher lipid content than its leaves at Day 7. Lipid metabolism genes undergoing cell-fate changes were studied. The mRNA expression of the lipid catabolism genes, acyl-CoA oxidase 1 and 2 (ACX1, ACX2) and multifunctional protein ...

The genus Capsicum belongs to the Solanaceae botanical family and is notable for the production of secondary metabolites of medicinal and economical importance. In vitro methods have been successfully utilized for the large scale production of plant secondary metabolites. The objective of this study was to establish a protocol for callus induction from leaves, nodal and internodal segments of the cultivar C. annuum var. annuum cv. Iberaba Jalapeño, and to determine the growth pattern of the calluses, aiming at the identification of the deceleration phase, when the callus cells must be subcultured for the establishment of cell suspensions and the production of secondary metabolites.

The healing of fractures in intact rats after PTH administration has not been studied before. However, PTH treatment has been used in two studies on the healing of fractures in rats with pathologic bone metabolism and delayed fracture healing.25, 26 Kim et al.20 used ovariectomized rats and showed that the decreased mechanical strength seen in fractures after 28 days of healing could be partly prevented by giving the animals 175 μg of PTH(1-84)/kg/day. This dose corresponds with the 60 μg of PTH(1-34)/kg/day used in our experiment (18 nmol and 15 nmol, respectively), and equal molar of PTH(1-84) and PTH(1-34) induces equal anabolic bone effects when given to rats in the dose-range 1.1-30 nmol.7, 15 Fukuhara and Mizuno19 studied parathyroidectomized rats with and without PTH administration during the first 5 weeks of healing. Applying histologic techniques, they found that PTH administration enhanced both bone formation and resorption in the early stage of healing, whereas bone resorption was ...

Managing Corns and Calluses in the Elderly (2/24/09)-It is estimated that the average person will walk the equivalent of three times around the earth in a lifetime. Can you imagine the wear and tear this puts on the 26 bones, 33 joints and over 100 tendons, ligaments and muscles that make up the foot? A survey for the American Podiatric Medical Association reported 53 percent of respondents had foot pain so severe that it hampered their daily function. On average, people develop pain in their 60s, but it can start as early as the 20s and 30s. Yet, except for women who get regular pedicures, most people dont take much care of their feet.. (4/21/02)-One of the most painful and disabling conditions found in the elderly relates to foot and toe problems. It is estimated that about 7.5 million Americans consult physicians with these problems. The figures we see quoted are nearly four million for corns and calluses. Many individuals complain about their feet, never consult a physician, and try over ...

Fracture healing should be monitored radiographically to determine the progression of healing. The time interval between re-examinations depends on the severity of the fracture, the type of repair and the clinical reassessment of the patient. Following initial mineral resorption along the fracture line, and formation of a fibrous callus, calcified periosteal and endosteal callus develops. 12) and the presence or absence of concurrent infection. Endosteal callus is more difficult to visualize radiographically, but ultimately results in disappearance of the fracture line. G. 5 weeks after a kick injury.
