Enlargement of the thymus. A condition described in the late 1940's and 1950's as pathological thymic hypertrophy was status thymolymphaticus and was treated with radiotherapy. Unnecessary removal of the thymus was also practiced. It later became apparent that the thymus undergoes normal physiological hypertrophy, reaching a maximum at puberty and involuting thereafter. The concept of status thymolymphaticus has been abandoned. Thymus hyperplasia is present in two thirds of all patients with myasthenia gravis.

The epizootiology and pathogenesis of thyroid hyperplasia in coho salmon (Oncorhynchus kisutch) in Lake Ontario. (1/4620)

The thyroid glands of coho salmon collected at different stages of their anadromous migration exhibited progressive and extensive hyperplasia and hypertrophy. The incidence of overt nodule formation rose from 5% in fish collected in August to 24% in fish collected in October. The histological picture of the goiters was similar to that found in thiourea-treated teleosts and thiouracil-treated mammals. There was a concomitant, significant decrease in serum thyroxine and triiodothyronine values between September and October (thyroxine, 1.0+/-0.3 mug/100 ml and 0.4 mug/100 ml in September and October, respectively; triiodothyronine, 400.3+/-51.6 ng/100 ml and 80.2 ng/100 ml in September and October, respectively) and marked hypertrophy and hyperplasia of thyrotrophs. These data indicate a progressive hypothyroid condition which, although it may be linked to iodide deficiency, may well be enhanced by other environmental factors. The evidence for involvement of other factors is discussed.  (+info)

Natural history of papillary lesions of the urinary bladder in schistosomiasis. (2/4620)

Variable epithelial hyperplasia was observed in urinary bladder of nine capuchin monkeys (Cebus apella) when examined at cystotomy 94 to 164 weeks after infection with Schistosoma haematobium. These hosts were followed for 24 to 136 weeks postcystotomy to determine the status of bladder lesions in relation to duration of infection and to ascertain whether lesion samples removed at cystotomy reestablished themselves in autologous and heterologous transfers. There was involution of urothelial hyperplasia in eight of nine animals and no evidence for establishment of transplanted bladder lesions.  (+info)

Ganglioneuromas and renal anomalies are induced by activated RET(MEN2B) in transgenic mice. (3/4620)

Multiple endocrine neoplasia type 2B (MEN2B) is an autosomal dominant syndrome characterized by the development of medullary thyroid carcinoma, pheochromocytomas, musculoskeletal anomalies and mucosal ganglioneuromas. MEN2B is caused by a specific mutation (Met918-->Thr) in the RET receptor tyrosine kinase. Different mutations of RET lead to other conditions including MEN2A, familial medullary thyroid carcinoma and intestinal aganglionosis (Hirschsprung disease). Transgenic mice were created using the dopamine beta-hydroxylase promoter to direct expression of RET(MEN2B) in the developing sympathetic and enteric nervous systems and the adrenal medulla. DbetaH-RET(MEN2B) transgenic mice developed benign neuroglial tumors, histologically identical to human ganglioneuromas, in their sympathetic nervous systems and adrenal glands. The enteric nervous system was not affected. The neoplasms in DbetaH-RET(MEN2B) mice were similar to benign neuroglial tumors induced in transgenic mice by activated Ras expression under control of the same promoter. Levels of phosphorylated MAP kinase were not increased in the RET(MEN2B)-induced neurolglial proliferations, suggesting that alternative pathways may play a role in the pathogenesis of these lesions. Transgenic mice with the highest levels of DbetaH-RET(MEN2B) expression, unexpectedly developed renal malformations analogous to those reported with loss of function mutations in the Ret gene.  (+info)

Anti-monocyte chemoattractant protein-1/monocyte chemotactic and activating factor antibody inhibits neointimal hyperplasia in injured rat carotid arteries. (4/4620)

Monocyte chemoattractant protein-1 (MCP-1)/monocyte chemotactic and activating factor (MCAF) has been suggested to promote atherogenesis. The effects of in vivo neutralization of MCP-1 in a rat model were examined in an effort to clarify the role of MCP-1 in the development of neointimal hyperplasia. Competitive polymerase chain reaction analysis revealed maximum MCP-1 mRNA expression at 4 hours after carotid arterial injury. Increased immunoreactivities of MCP-1 were also detected at 2 and 8 hours after injury. Either anti-MCP-1 antibody or nonimmunized goat IgG (10 mg/kg) was then administered every 12 hours to rats that had undergone carotid arterial injury. Treatment with 3 consecutive doses of anti-MCP-1 antibody within 24 hours (experiment 1) and every 12 hours for 5 days (experiment 2) significantly inhibited neointimal hyperplasia at day 14, resulting in a 27.8% reduction of the mean intima/media ratio (P<0.05) in experiment 1 and a 43.6% reduction (P<0.01) in experiment 2. This effect was still apparent at day 56 (55.6% inhibition; P<0.05). The number of vascular smooth muscle cells in the neointima at day 4 was significantly reduced by anti-MCP-1 treatment, demonstrating the important role of MCP-1 in early neointimal lesion formation. However, recombinant MCP-1 did not stimulate chemotaxis of vascular smooth muscle cells in an in vitro migration assay. These results suggest that MCP-1 promotes neointimal hyperplasia in early neointimal lesion formation and that neutralization of MCP-1 before, and immediately after, arterial injury may be effective in preventing restenosis after angioplasty. Further studies are needed to clarify the mechanism underlying the promotion of neointimal hyperplasia by MCP-1.  (+info)

Myometrial zonal differentiation and uterine junctional zone hyperplasia in the non-pregnant uterus. (5/4620)

Human non-gravid myometrium differentiates in response to ovarian sex steroids into a subendometrial layer or junctional zone and an outer myometrial layer. Compared to the outer myometrial layer, the junctional zone myocytes are characterized by higher cellular density and lower cytoplasmic-nuclear ratio. These structural differences allow in-vivo visualization of the myometrial zonal anatomy by T2-weighted magnetic resonance (MR) imaging. The human myometrium is also functionally polarized. Video-vaginosonography studies have shown that propagated myometrial contractions in the non-pregnant uterus originate only from the junctional zone and that the frequency and orientation of these contraction waves are dependent on the phase of the menstrual cycle. The mechanisms underlying zonal myometrial differentiation are not known, but growing evidence suggests that ovarian hormone action may be mediated through cytokines and uterotonins locally released by the basal endometrial layer and endometrio-myometrial T-lymphocytes. Irregular thickening of the junctional zone due to inordinate proliferation of the inner myometrium, junctional zone hyperplasia, is a common MR finding in women suffering from menstrual dysfunction. Preliminary data suggest that junctional zone hyperplasia is further characterized by loss of normal inner myometrial function. Although irregular thickening of the junctional zone has been associated with diffuse uterine adenomyosis, the precise relationship between subendometrial smooth muscle proliferation and myometrial invasion by endometrial glands and stroma remains to be established.  (+info)

Mechanism of parathyroid tumourigenesis in uraemia. (6/4620)

Clonal analysis has shown that in renal hyperparathyroidism (2-HPT), parathyroid glands initially grow diffusely and polyclonally after which the foci of nodular hyperplasia are transformed to monoclonal neoplasia. There is a great deal of information about genetic abnormalities contributing to the tumourigenesis of parathyroid neoplasia in primary hyperparathyroidism. It is speculated that allelic loss of the MEN1 suppressor gene and overexpression of cyclin D1 induced by rearrangement of the parathyroid hormone gene may be the major genetic abnormality in sporadic parathyroid adenoma but not in 2-HPT. The pathogenesis of 2-HPT, abnormality of the Ca2+-sensing receptor (CaR) gene and the vitamin D receptor gene may possibly contribute to parathyroid tumourigenesis in 2-HPT. However, this is not yet clear and heterogeneous and multiple genetic abnormalities may be responsible for the progression of secondary parathyroid hyperplasia.  (+info)

Accelerated intimal hyperplasia and increased endogenous inhibitors for NO synthesis in rabbits with alloxan-induced hyperglycaemia. (7/4620)

1. We examined whether endogenous inhibitors of NO synthesis are involved in the augmentation of intimal hyperplasia in rabbits with hyperglycaemia induced by alloxan. 2. Four weeks after the endothelial denudation of carotid artery which had been performed 12 weeks after alloxan, the intimal hyperplasia was greatly augmented with hyperglycaemia. The degree of hyperplasia was assessed using three different parameters of histopathological findings as well as changes in luminal area and intima: media ratio. 3. There were positive and significant correlations between intima:media ratio, plasma glucose, and concentrations of N(G)-monomethyl-L-arginine (L-NMMA) and N(G), N(G)-dimethyl-L-arginine (ADMA) in endothelial cells, that is, the intima:media ratio became greater as plasma glucose and endothelial L-NMMA and ADMA were increased. Furthermore, endothelial L-NMMA and ADMA were increased in proportion to the increase in plasma glucose. 4. In contrast, there were inverse and significant correlations between cyclic GMP production by carotid artery strips with endothelium and plasma glucose, between cyclic GMP production and endothelial L-NMMA and ADMA, and between the intima:media ratio and cyclic GMP production. 5. Exogenously applied L-NMMA and ADMA inhibited cyclic GMP production in a concentration-dependent manner. IC50 values were determined to be 12.1 microM for the former and 26.2 microM for the latter. The cyclic GMP production was abolished after the deliberate removal of endothelium from the artery strips. 6. These results suggest that the augmentation of intimal hyperplasia with hyperglycaemia is closely related to increased accumulation of L-NMMA and ADMA with hyperglycaemia, which would result in an accelerated reduction in NO production/release by endothelial cells.  (+info)

Expression of relaxin-like factor is down-regulated in human testicular Leydig cell neoplasia. (8/4620)

In addition to their role in steroidogenesis in the male, testicular Leydig cells constitutively express large amounts of the peptide relaxin-like factor (RLF), also known as Ley-IL. The Leydig cell-derived RLF belongs to the insulin-like superfamily, which also includes relaxin, insulin and the insulin-like growth factors, and within the testis is a specific marker of Leydig cells. Little information is available either on the regulation of gene expression or on the function of this Leydig cell-derived peptide. In the present study we have investigated the expression pattern of human RLF in patients with rare Leydig cell hyperplasia and adenoma. The expression of both mRNA and protein appear to be decreased in hyperplastic Leydig cells, whereas in the Leydig cell adenomas studied, large central areas of the adenoma were devoid of RLF mRNA and protein. Only Leydig cells located at the periphery of the adenoma displayed expression of RLF, with full agreement between in-situ hybridization and immunohistochemistry. It thus appears that the expression of the RLF gene and its products are down-regulated in Leydig cell hyperplasia and adenoma, consistent with a concomitant dedifferentiation of these cells.  (+info)

Neurofibromin 2 (NF2), a potent tumor suppressor, is reported to inhibit proliferation in several cell types. The role of NF2 in neointima hyperplasia after vascular injury is unknown. We explored the role of NF2 in proliferation, migration of vascular smooth muscle cell (VSMC) and neointima hyperplasia after vascular injury. NF2 phosphorylation was elevated in VSMC subjected to platelet-derived growth factor (PDGF)-BB and in artery subjected to vascular injury. Mice deficient for Nf2 in VSMC showed enhanced neointima hyperplasia after injury, increased proliferation and migration of VSMC after PDGF-BB treatment. Mechanistically, we observed increased nuclear p-NF2, declined p-Yes-Associated Protein (YAP), nuclear translocation of YAP after PDGF-BB treatment or injury. NF2 knockdown or YAP overexpression showed similar phenotype in VSMC proliferation, migration and neointima hyperplasia. YAP inhibition abolished the above effects mediated by NF2 knockdown. Finally, NF2 knockdown further promoted

net friend Suri: this year the company routine physical examination found that there is hyperplasia of mammary glands, the doctor asked a number of attention, one of which is not to eat chicken, mammary gland hyperplasia really cant eat chicken? Breast hyperplasia patients in the diet should pay attention to what problems? patients with breast hyperplasia diet should be light patients with hyperplasia of mammary glands to try to eat light food, eat less fried barbecue food, drink soup, meat intake is not too much, especially not to eat chicken reared in captivity, whether chickens contain certain hormones, and whether it will cause endocrine disorders, it is not too clear. However, the choice of healthy meat is no doubt the premise of promoting health, and long-term eating more meat, leading to excessive intake of fat and protein, is one of the causes of breast disease. Therefore, it is more appropriate for patients with hyperplasia of mammary gland to control the intake of poultry food. breast ...
TY - JOUR. T1 - Acidophilic nuclear inclusions are specific for florid ductal hyperplasia among proliferative breast lesions. AU - Lauer, Scott. AU - Oprea-Ilies, Gabriela. AU - Cohen, Cynthia. AU - Adsay, Volkan. AU - Adams, Amy L.. PY - 2011/6/1. Y1 - 2011/6/1. N2 - Context.-Recently we have observed distinctive acidophilic intranuclear inclusions in cases of usual intraductal hyperplasia of the breast. Similar inclusions were described almost 20 years ago in cases of mammary hyperplasia. These correlated ultrastructurally with so-called helioid inclusions. However, there since has been little discussion of these inclusions in the literature. Objective.-To examine the incidence and specificity of these inclusions in proliferative lesions of the breast. Design.-Forty cases of usual intraductal hyperplasia, 15 cases of atypical ductal hyperplasia, and 34 cases of lowgrade ductal carcinoma in situ were examined for the presence of acidophilic intranuclear inclusions. Results.-Acidophilic ...
Hyperplasia may be due to any number of causes, including proliferation of basal layer of epidermis to compensate skin loss, chronic inflammatory response, hormonal dysfunctions, or compensation for damage or disease elsewhere.[11] Hyperplasia may be harmless and occur on a particular tissue. An example of a normal hyperplastic response would be the growth and multiplication of milk-secreting glandular cells in the breast as a response to pregnancy, thus preparing for future breast feeding.[12] Perhaps the most interesting and potent effect IGF has on the human body is its ability to cause hyperplasia, which is an actual splitting of cells.[13] By contrast, hypertrophy is what occurs, for example, to skeletal muscle cells during weight training and steroid use and is simply an increase in the size of the cells.[14] With IGF use, one is able to cause hyperplasia which actually increases the number of muscle cells present in the tissue.[15] Weight training with or without anabolic steroid use ...

TY - JOUR. T1 - Risk factors for atherosclerosis and the development of preatherosclerotic intimal hyperplasia. AU - Cizek, Stephanie M.. AU - Bedri, Shahinaz. AU - Talusan, Paul. AU - Silva, Nilsa. AU - Lee, Hang. AU - Stone, James R.. PY - 2007/11. Y1 - 2007/11. N2 - Background: Intimal hyperplasia or thickening is considered to be the precursor lesion for atherosclerosis in humans; however, the factors governing its formation are unclear. To gain insight into the etiology of preatherosclerotic intimal hyperplasia, we correlated traditional risk factors for atherosclerosis with the intimal hyperplasia in an atherosclerosis-resistant vessel, the internal thoracic artery. Methods: Paired internal thoracic arteries were obtained from 89 autopsies. Multivariate logistic regression and multiple regression models were used to examine the association of preatherosclerotic intimal hyperplasia with traditional risk factors for atherosclerosis: age, gender, hypertension, smoking, body mass index, ...
Neointimal hyperplasia refers to proliferation and migration of vascular smooth muscle cells primarily in the tunica intima, resulting in the thickening of arterial walls and decreased arterial lumen space. Neointimal hyperplasia is the major cause of restenosis after percutaneous coronary interventions such as stenting or angioplasty. The term neointima is used because the cells in the hyperplastic regions of the vascular wall have histological characteristics of both intima and normal artery cells. Neointimal hyperplasia first develops with damage to the arterial wall, followed by platelet aggregation at site of injury, recruitment of inflammatory cells, proliferation and migration of vascular smooth muscle cells, and collagen deposition. Mechanical injury of arterials due to stretching of arterial walls with a balloon catheter results in the recruitment of cells such as monocytes, macrophages, and neutrophils to the site of injury. Macrophages in particular express many growth factors, ...
The p53-ull mammary epithelial model differs from the traditional mouse models of mammary tumorigenesis in several fundamental biological properties (5 , 6) . The traditional mouse models of mammary tumorigenesis, which are induced by mouse mammary tumor virus standard, arise from alveolar hyperplasias. These alveolar hyperplasias are negative for ER at the onset and generate ER-negative, hormone-independent tumors. In chemical carcinogen-treated mice, tumors arise from both alveolar hyperplasias and ductal hyperplasias. However, tumors are primarily hormone independent. Because the p53-null normal mammary epithelium and the serially transplanted, immortalized ductal outgrowths were ER positive, it was of interest to determine the hormonal dependency of preneoplastic progression in these cells.. The hormonal dependency of the p53-null normal mammary epithelium is indistinguishable from that of the p53 wild-type epithelium. Previous results demonstrated that growth and morphogenesis in ...

AIMS--To determine if allelic loss on chromosomes 16q and 17p, commonly encountered in in situ and invasive ductal carcinomas, is present in atypical ductal hyperplasia (ADH); to determine whether ADH is a neoplastic (clonal) or hyperplastic (polyclonal) proliferation. METHODS--Fourteen cases of ADH were examined for allele loss at loci on chromosome 16q and 17p using a microdissection technique, polymorphic DNA markers and the polymerase chain reaction (PCR). RESULTS--Loss of heterozygosity (LOH) was detected in five of nine informative cases on chromosome 16q at the microsatellite D16S413 and two of eight informative cases on chromosome 17p at D17S796. CONCLUSIONS--The incidence of LOH at these loci is similar to that previously observed in ductal carcinoma in situ and in invasive ductal carcinoma. Because of the nature of the technique used, our findings also demonstrate that ADH is a monoclonal, and hence, neoplastic proliferation rather than a hyperplastic (polyclonal) condition as its name ...
Background: To explore the hypothesis that tissue iron and reactive oxygen species, including superoxide (O2), mediate acute inflammatory and late hyperplastic responses to vascular injury, we studied experimental overdistension of normal carotid and femoral arteries in dogs. Experimental design: Arterial segments isolated in situ were distended with Ringer solution at 2 atmospheres pressure. In initial experiments the arteries were excised immediately after distension and immersed in diaminobenzidine solutions containing Mn++ ions to initiate histochemical reactions for O2. In other experiments distended arterial segments were reperfused with arterial blood in the presence or absence of the iron chelator, deferoxamine, or the low-cost superoxide dismutase mimic, manganese chloride, and examined microscopically at 3 hours, 7 days, or 30 days. The degree of acute inflammation or smooth muscle hyperplasia was determined by quantitative morphometry; free iron capable of redox cycling was determined
Atypical ductal hyperplasia (ADH) is a common diagnosis in the mammographic era and a significant clinical problem with wide variation in diagnosis and treatment. After a diagnosis of ADH on biopsy a proportion are upgraded to carcinoma upon excision; however, the remainder of patients are overtreated. While ADH is considered a non-obligate precursor of invasive carcinoma, the molecular taxonomy remains unknown. Although a few studies have revealed some of the key genomic characteristics of ADH, a clear understanding of the molecular changes associated with breast cancer progression has been limited by inadequately powered studies and low resolution methodology. Complicating factors such as family history, and whether the ADH present in a biopsy is an isolated lesion or part of a greater neoplastic process beyond the limited biopsy material, make accurate interpretation of genomic features and their impact on progression to malignancy a challenging task. This article will review the definitions and

Hyperplasia (or hypergenesis) is a general term referring to the proliferation of cells within an organ or tissue. Hyperplasia may result in the gross enlargement of an organ, the formation of a benign tumor. Hyperplasia is considered to be a physiological response to a specific stimulus, and the cells of a hyperplastic growth remain subject to normal regulatory control mechanisms. This stands in contrast to neoplasia (the process underlying cancer and some benign tumors), in which genetically abnormal cells proliferate in a non-physiological manner which is unresponsive to normal stimuli.[1] ...

Hyperplasia refers to an increase in the number of cells within a tissue due to mitosis. It is important to note that hyperplastic cells still maintain strict regulatory control of their cell cycle. Consequently, when the stimuli which induce hyperplasia are removed, cells will terminate their divisions. In contrast, cell division in the absence of stimuli is considered neoplasia ...
Another interesting finding in our study is that women greater than 55 years of age with atypia had increased ER expression compared with younger women with atypia. This differs from the previous report by Shoker and colleagues (7) who found that ER expression was high in atypical ductal hyperplasia, ductal carcinoma in situ and lobular neoplasia regardless of age. The number of samples in that study was somewhat small; 23 cases of atypical hyperplasia, 43 cases of ductal carcinoma in situ, and 32 cases of lobular neoplasia. The authors suggested that in atypia and carcinoma in situ the regulation of ER expression may escape the normal age-related regulatory mechanisms. ER expression and relationship to age has also been studied in hyperplastic enlarged lobular units, a common alteration of the normal TDLU and potential precursor of breast cancer. Lee and colleagues (21) have shown that ER expression in hyperplastic enlarged lobular units is increased in postmenopausal woman compared with ...
The cytoplasmic signal adaptor protein designated sequestosome1 (SQSTM1) (A170 in mouse, ZIP in rat or p62 in human) plays a key role in modulating signal transduction via membrane receptors. SQSTM1 has a UBA ubiquitin-binding domain in the C-terminus and participates in the assembly of ubiquitinated protein aggregates termed sequestosome and modulation of ubiquitination pathways involved in NF-κB activity and receptor trafficking. We have found that deficiency of SQSTM1 in mice exhibits mature-onset obesity accompanied by insulin and leptin resistance. We previously established that redox sensitive transcription factor Nrf2 upregulates SQSTM1 expression in response to atherogenic stimuli or laminar shear stress in vascular cells, and here examine role of SQSTM1 in neointimal hyperplasia and vascular remodeling in vivo following carotid artery ligation. Neointimal hyperplasia was markedly enhanced at proximal sites of ligation after 3 weeks in SQSTM1−/− (n=10) compared with wild type mice ...
A method is provided for reducing the occurrence of anastomotic intimal hyperplasia in grafts of artery, vein, biologic or synthetic conduits having end-to-side distal anastomosis. The method includes administering a regimen of fractionated heparin to the subject. Administration of the fractionated heparin can be either intravenously, intraperitoneally, subcutaneously or orally. Preferred dosage is 50-80 mg./kg. body weight per day.
Women with atypical hyperplasia (also known as atypia) are at higher risk of developing breast cancer in future than previously thought.
Health Shield is a patented natural herbal supplement that is effective in giving greater control of mammary hyperplasia and can diminish erratic cell propagation systemically. Health Shield was originally developed for preventive for women with mammary hyperplasia, tumors, and breast cancer.. According to medical statistics, middle-aged women have the highest incidence in developing breast cancer while 3% of all women with mammary hyperplasia will eventually develop breast cancer. The mortality rate of breast cancer is significantly higher than mammary hyperplasia. Even though early life saving surgery can be done to excise tumors, women who go through with this procedure will still have to go through mental and physical stress during the healing process which can last a lifetime. According to traditional herbal medicine, the breast lump is the basis of breast cancer. Breast lumps can be caused by menstrual disorder, emotional frustration, depression, internal and emotion injury, accumulation ...

Since the 1920s, it has been a dogma that the only manner of normalising LV wall stress, for example during systemic hypertension, is to increase cardiac mass by means of hypertrophy (Karsner et al., 1925; Petersen and Baserga, 1965; Morkin and Ashford, 1967; Morkin and Ashford, 1968), where the myocytes are thickening due to parallel replication of sarcomeres (Dorri et al., 2007). Since then, however, a number of recent investigations of both healthy and sick hearts have shown that hyperplasia can occur after the postnatal period (Linzbach, 1960; Olivetti et al., 1994; Beltrami et al., 1995; Anversa and Kajstura, 1998; Beltrami et al., 2001; Leri et al., 2002; Engel, 2005; Brüel et al., 2007b; Du et al., 2010). It is likely that the pathophysiological response to increased afterload elicits both a hypertrophic response, and a hyperplastic response with formation of- and parallel placement of new cardiomyocytes (Kajstura et al., 1994). Importantly, the combined response to chronically increased ...

CMV is thought to be a key pathogen involved in the pathogenesis of TV in human allografts. To evaluate the direct effect of CMV infection on vascular biology, we used a rat model in which aortic allografts were infected ex vivo with RCMV prior to transplantation. We chose 2 time points after transplantation to investigate the development of TV, 2 weeks that represented the early phase of TV in rats; and 8 weeks, when TV was fully developed. We found that RCMV influenced vascular remodeling by increased apoptosis of SM-α-actin positive cells in the media layer, decreased extracellular matrix deposits and increased intimal hyperplasia. Moreover, RCMV induced a strong infiltration of CD68-positive macrophages mainly in the adventitia and resulted in an increase of MCP-1 in the allograft, which resulted in migration of adventitial cells towards the intima that most likely also contributed to intimal hyperplasia.. Vessel stability is sustained by a balance between cellular proliferation and ...

Cellular hypertrophy is a fundamental response of the stressed heart. Many of the pathways associated with cell division are known to be activated in this hypertrophic response, leading to the hypothesis that cardiomyocyte hypertrophy might be the result of a fundamental block in karyokinesis and cytokinesis, by which the adult cardiomyocyte is unable to disassemble sarcomeres, uncouple from neighboring cells and divide (Ahuja et al., 2007). Nuclear division and polyploidy are observed in the latest stages of human heart failure and reverse with ventricular unloading, but cellular dynamics earlier in the pathophysiological cascade have not yet been explored (Rivello et al., 2001). In the zebrafish model that we generated, we were able to explore the effects of disrupted sarcomere gene function during cardiogenesis. We found that when the embryonic heart is exposed to a hypertrophic stimulus, in contrast to the response in the adult mammalian heart, a hyperplastic response occurs. Whereas ...

Pseudoepitheliomatous hyperplasia, also called Hecks disease, is an epithelial, inconstant and conjunctive proliferation that develops as a response to a great variety of stimuli. It is a lesion associated to different diseases, being found in the following etiopathogenic conditions: infectious pathogenic conditions, tumoral pathogenic conditions, inflammatory pathogenic conditions. We studied oral pseudoepitheliomatous hyperplasia for which we performed a histopathological study, on a group of 47 cases of oral pseudoepitheliomatous hyperplasias, where we investigated the following: oral epithelium changes, changes in the underlying lamina propria and associated etiopathogenic conditions. The main changes of the oral epithelium were: elongation of the epithelial apexes (17.02%), acanthosis (100%), dyskeratosis (14.89%), and in the underlying lamina propria: fibrosis (29.78%), inflammatory infiltrate (70.21%) and vascular proliferation (10.64%).

There are no current recommended screening tests for uterine cancer.. Women with high risk for endometrial cancer or atypical hyperplasia may be screened. Screening is recommended only for those with certain risk factors, such as Lynch syndrome colorectal cancer, a rare familial syndrome in which multiple family members often develop colorectal and other tumors. These women should be followed closely by a doctor or team of doctors with expertise in cancer genetics. For a period of years, screening was recommended for all women taking tamoxifen, but the current recommendation is not to screen, but to test if uterine bleeding occurs.. If you have symptoms such as vaginal bleeding after you go through menopause, or heavy or irregular bleeding before menopause, you should discuss these with your doctor. ...
Pancreatic cancer, the fourth commonest cause of death in the United States, has a very poor prognosis, is increasing in incidence, and, in most cases, is not detected before it has spread beyond the pancreas. Partial, or total, pancreatectomy has increased five-year survival in only a small fraction of cases. New techniques are helpful in earlier diagnosis, but patients have to be selected for examination long before clinical signs or symptoms develop. Elderly patients who use alcohol and tobacco excessively and female diabetics may be at higher risk. Pathologists should examine pancreasduct epithelium at autopsy in patients in the fourth to sixth decades for atypia, papillary hyperplasia, carcinoma in situ, or other possible precursor changes. Diagnostic tumor, or oncofetal antigens, or a biochemical difference in isozyme activities, hopefully, may be developed. Some combinations of surgery, chemotherapy, and radiation therapy may give better prognosis.

The laboratory focuses on understanding the mechanisms of acute and chronic rejection in solid-organ allografts, and more broadly examining the interactions of inflammatory cells with vessel walls. These processes have direct relevance not only to transplantation, but also to in-stent restenosis, vein graft intimal hyperplasia, and atherosclerosis. In vivo murine aortic and cardiac allografts constitute a significant portion of the research, with patterned co-cultures and nanotechnology being increasingly used to model the interactions of innate and adaptive immune elements with endothelial or smooth muscle cells. Monoclonal antibody blockade and/or targeted deletions or knock-downs of various cytokines, chemokines, or their receptors permit examination of the roles of selected mediators and costimulatory molecules. Potential therapeutic strategies are also being formally tested in the various models. This work has shown the critical role of interferon-g in driving allograft arteriopathy and of ...
VSMC and HUVEC proliferation and apoptosis were measured by BrdU and TdT staining, respectively. Balloon injury of the right carotid was produced in Wistar rats. Straight after the vascular injury, the balloon-dilated arteries were randomly transfected with p85active (n = 8), dominant negative p85 (p85DN) (n = 8) or green fluorescent protein (GFP, n = 6; controls). Transfection of p85active decreased VSMC proliferation in the absence of cAMP while cAMP inhibition of VSMC growth was prevented by p85DN. p85active formed a stable complex with ras proteins, resulting in a selective switch-off of ras effectors in VSMCs. On the other hand, p85active did not affect HUVEC growth in vitro. Interestingly, p85active significantly reduced VSMC and HUVEC apoptosis in vitro. In both vascular cell lineages, p85active increased while p85DN decreased Akt phosphorylation. Importantly, the in vivo transfection of activated p85-active significantly reduced VSMC proliferation and then neointimal formation after ...

Testimonials and practice show that IGF-1 LR3 is an excellent choice both for drying and for providing qualitative muscle growth (due to hypertrophy and hyperplasia). The drug is relevant for applying different age groups, levels of training and at the same time regardless of sex. In other words, for sports purposes it can be relatively safe to use both men and women, and amateurs, and sports professionals.. IGF-1LR3: detailed description. If you disclose IGF-1LR3 in terms of properties, it is a biologically active peptide that has an anabolic effect and promotes the process of muscle hyperplasia. It also mediates the action of growth hormone, so the improvements they provide are largely comparable (in humans, growth hormone is not completely independent, its effects (fat burning, muscle growth, etc.) are largely mediated by an insulin-like growth factor ...
