    Although cervical cancer is preventable with early detection, it remains the second most common malignancy among women. An understanding of how proteins change in their expression during a particular diseased state such as cervical cancer will contribute to an understanding of how the disease develops and progresses. Potentially, it may also lead to the ability to predict the occurrence of the disease. With this in mind, we aimed to identify differentially expressed proteins in the plasma of cervical cancer patients. Plasma from control, cervical intraepithelial neoplasia (CIN) grade 3 and squamous cell carcinoma (SCC) stage IV subjects was resolved by two-dimensional gel electrophoresis and the resulting proteome profiles compared. Differentially expressed protein spots were then identified by mass spectrometry. Eighteen proteins were found to be differentially expressed in the plasma of CIN 3 and SCC stage IV samples when compared with that of controls. Competitive ELISA further validated the expression of cytokeratin 19 and tetranectin. Functional analyses of these differentially expressed proteins will provide further insight into their potential role(s) in cervical cancer-specific monitoring and therapeutics.

    Suberonylanilide hydroxamic acid (SAHA) is an orally administered histone deacetylase inhibitor (HDACI) that has shown significant antitumour activity in a variety of tumour cells. To identify proteins involved in its antitumour activity, we utilized a proteomic approach to reveal protein expression changes in the human cervical cancer cell line HeLa following SAHA treatment. Protein expression profiles were analysed by 2-dimensional polyacrylamide gel electrophoresis (2-DE) and protein identification was performed on a MALDI-Q-TOF MS/MS instrument. As a result, a total of nine differentially expressed proteins were visualized by 2-DE and Coomassie brilliant blue (CBB) staining. Further, all the changed proteins were positively identified via mass spectrometry (MS)/MS analysis. Of these, PGAM1 was significantly downregulated in HeLa cells after treatment with SAHA. Moreover, PGAM1 has been proven to be downregulated in another cervical cancer cell line (CaSki) by western blot analysis. Together, using proteomic tools, we identified several differentially expressed proteins that underwent SAHA-induced apoptosis. These changed proteins may provide some clues to a better understanding of the molecular mechanisms underlying SAHA-induced apoptosis in cervical cancer.

  3. Preliminary comparative proteomics study of cervical carcinoma tissues with different sensitivity to concurrent chemoradiotherapy

    International Nuclear Information System (INIS)

    Objective: To investigate the proteomics differences between the high-sensitivity(HS) and the low-sensitivity(LS) groups of cervical carcinoma treated by concurrent chemoradiotherapy, and to confirm the sensitivity associated proteins in intermediate stage and advanced cervical carcinoma. Methods: Fresh carcinoma tissues were collected from 10 untreated cervical carcinoma patients. According to the response to concurrent chemoradiotherapy, the tissues were classified into HS group and LS group. In the first part of our experiment, protein separation was performed using two-dimensional gel electrophoresis (2-DE) with Amersham 18 cm linear pH 3-10 immobilized pH gradient(IPG) strips. The images of the gels were analyzed by PD-quest 7.0 software to find the differentially expressed protein-spots in each group. Then the differentially expressed protein-spots were incised from the gels and digested by trypsin. The peptide mass fingerprintings (PMF) was acquired by matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). The proteins were identified by data searched in the Mascot-database. Two differentially expressed proteins were assayed by western blot and immunohistochemical methods. Results: Most of the gels were clear and successfully analyzed by PD-quest 7.0 software. Most of the protein-spots concentrated on the area of 20-100 KDa(Mw) and pH4-8. The average number of the protein-spots was 781 ± 74 in HS group and 766 ± 52 in LS group. The match rate was 87.6% between the two groups. Eight proteins highly in HS group but lowly expressed in LS group included hemoglobin subunit beta, caspase-14 precursor, calmodulindike, S100-A9 protein(MRP-14), galectin-7, HSKERC4, keratin 19 and actin. Ten proteins highly in LS group but lowly expression in HS group included anti HBs antibody light-chain Fab, lamin-B1, WARS protein, flavin reductase, glutamate dehydrogenase 1, nuclear matrix protein 238, retinal dehydrogenase 1, AF165172

    Full Text Available Abstract Background Lymph node status is not part of the staging system for cervical cancer, but provides important information for prognosis and treatment. We investigated whether lymph node status can be predicted with proteomic profiling. Material & methods Serum samples of 60 cervical cancer patients (FIGO I/II were obtained before primary treatment. Samples were run through a HPLC depletion column, eliminating the 14 most abundant proteins ubiquitously present in serum. Unbound fractions were concentrated with spin filters. Fractions were spotted onto CM10 and IMAC30 surfaces and analyzed with surface-enhanced laser desorption time of flight (SELDI-TOF mass spectrometry (MS. Unsupervised peak detection and peak clustering was performed using MASDA software. Leave-one-out (LOO validation for weighted Least Squares Support Vector Machines (LSSVM was used for prediction of lymph node involvement. Other outcomes were histological type, lymphvascular space involvement (LVSI and recurrent disease. Results LSSVM models were able to determine LN status with a LOO area under the receiver operating characteristics curve (AUC of 0.95, based on peaks with m/z values 2,698.9, 3,953.2, and 15,254.8. Furthermore, we were able to predict LVSI (AUC 0.81, to predict recurrence (AUC 0.92, and to differentiate between squamous carcinomas and adenocarcinomas (AUC 0.88, between squamous and adenosquamous carcinomas (AUC 0.85, and between adenocarcinomas and adenosquamous carcinomas (AUC 0.94. Conclusions Potential markers related with lymph node involvement were detected, and protein/peptide profiling support differentiation between various subtypes of cervical cancer. However, identification of the potential biomarkers was hampered by the technical limitations of SELDI-TOF MS.

  8. Isolation of basal and mucous cell populations from rabbit trachea

    International Nuclear Information System (INIS)

    The application of a unit gravity sedimentation procedure to monodispersed rabbit tracheal cells resulted in the isolation of enriched (2-fold to 2.5-fold) basal and mucous cell populations. Cellular integrity was confirmed by a trypan blue dye exclusion index of 93%, [3H] leucine incorporation, and ultrastructural analysis. Unit gravity sedimentation is an affective and rapid procedure for obtaining viable, homogeneous preparations of basal and mucous cells that may be used for in vitro studies of cellular proliferation, differentiation, and glycoprotein biosynthesis in respiratory mucous epithelia

    AIM: To explore the dynamic changes in the pressure of the lateral ventricle during acute brainstem hemorrhage and the changes of neural discharge of vagus nerve under the load of intracranial hypertension, so as to analyze their effects on the congestive degree of intestinal mucous membrane and the morphologic changes of intestinal mucous membrane.METHODS: An operation was made to open the skull to obtain an acute brainstem hemorrhage animal model.Microcirculatory microscope photography device and video recording system were used to determine the changes continuously in the caliber of jejunal mesenteric artery during brainstem hemorrhage and the changes with time in the congestion of jejunal mucosal villi. We used HE stain morphology to analyze the changes of duodenal mucosal villi. A recording electrode was used to calculate and measure the electric discharge activities of cervical vagus nerve.RESULTS: (1) We observed that the pressure of lateral cerebral ventricle increased transiently during acute brainstem hemorrhage; (2) The caliber of the jejunal mesenteric artery increased during brainstem hemorrhage.Analysis of red color coordinate values indicated transient increase in the congestion of jejunal mucous membrane during acute brainstem hemorrhage; (3) Through the analysis of the pathologic slice, we found enlarged blood vessels, stagnant blood, and transudatory red blood cells in the duodenal submucous layer; (4) Electric discharge of vagus nerve increased and sporadic hemorrhage spots occurred in duodenal mucous and submucous layer, when the lateral ventricle was under pressure.CONCLUSION: Brainstem hemorrhage could causeintracranial hypertension, which would increase the neural discharge of vagus nerve and cause the transient congestion of jejunal mucous membrane. It could cause hyperemia and diffused hemorrhage in the duodenal submucous layer 48 h after brainstem hemorrhage.

    Mucus performs numerous protective functions in vertebrates, and in fishes may defend them against harmful organisms, although often the evidence is contradictory. The function of the mucous cocoons that many parrotfishes and wrasses sleep in, while long used as a classical example of antipredator behaviour, remains unresolved. Ectoparasitic gnathiid isopods (Gnathiidae), which feed on the blood of fish, are removed by cleaner fish during the day; however, it is unclear how parrotfish and wrasse avoid gnathiid attacks at night. To test the novel hypothesis that mucous cocoons protect against gnathiids, we exposed the coral reef parrotfish Chlorurus sordidus (Scaridae) with and without cocoons to gnathiids overnight and measured the energetic content of cocoons. Fish without mucous cocoons were attacked more by gnathiids than fish with cocoons. The energetic content of mucous cocoons was estimated as 2.5 per cent of the fish's daily energy budget fish. Therefore, mucous cocoons protected against attacks by gnathiids, acting like mosquito nets in humans, a function of cocoons and an efficient physiological adaptation for preventing parasite infestation that is not used by any other animal.

    Desquamative gingivitis (DG) is a clinical condition in which the gingiva appears reddish, glazed, and friable with loss of superficial epithelium. DG is considered a clinical manifestation of many gingival diseases and hence not identified as a diagnosis itself. Mucous membrane pemphigoid (MMP) is an autoimmune vesiculobullous disorder of mucous membrane characterized by subepithelial bullae formation. MMP can affect the mucous membranes of oral cavity, conjunctiva, nasopharynx, larynx, esophagus, genitourinary tract, and anus and vary in its severity. The most commonly affected sites are oral cavity and conjunctiva. Since DG may be the early sign or only presenting sign of these conditions, most of the times, dental surgeon plays a key role in the diagnosis and prevention of the systemic complications of these diseases. We report a case of a 41-year-old male patient presented with DG. Histopathological examination revealed subepithelial clefting suggestive of MMP. The patient was treated with topical application of triamcinolone acetonide 0.1% 3-4 times a day for 1 month. PMID:27563211

  16. Possible association of mucous blanket integrity with postirradiation colonization resistance

    International Nuclear Information System (INIS)

    Radiation-induced infections can be associated with changes in colonization potential of the intestine. Since the mucous blanket, which overlays the epithelium, is a major mucosal structure and is heavily colonized by microorganisms, we examined the status of the mucus after radiation and evaluated susceptibility to intestinal challenge with bacteria. A downward shift (2.5 X 10(8) cells/g to 5.3 X 10(5)) of total facultatively anaerobic bacteria of the ileum of C3HeB/FeJ mice was detected by 3 days post exposure to 10 Gy 60Co. Numbers of flora returned to normal by 11 days after radiation. Scanning electron microscopy was used to show that the loss of bacteria could be associated with major disruptions of the continuity of the mucous blanket. The pathogen Pseudomonas aeruginosa adhered to mouse mucous films used in in vitro assays. When irradiated mice were challenged orally with 1 X 10(5) P. aeruginosa on days 1, 2, or 3 after irradiation, a progressive increase in susceptibility was seen, but no animals died before Day 4 postirradiation. Sensitivity to subcutaneous (sc) challenge with Pseudomonas also increased by Day 3 and was probably due largely to the profound neutropenia observed. Immunoglobulin G (Gamimmune), which protected burned mice infected with Pseudomonas, was ineffectual in treatment of 7 or 10 Gy irradiated mice challenged either orally or sc with the organism. The ileal mucosal barrier was compromised after radiation in ways which could facilitate epithelial colonization, an event which combined with other immunological and physiological decrements in this model can compromise the effectiveness of therapeutic modalities

    The Chinese giant salamander belongs to an old lineage of salamanders and endangered species. Many studies of breeding and disease regarding this amphibian had been implemented. However, the studies on the ultrastructure of this amphibian are rare. In this work, we provide a histological and ultrastructural investigation on posterior esophagus of Chinese giant salamander. The sections of amphibian esophagus were stained by hematoxylin & eosin (H&E). Moreover, the esophageal epithelium was observed by transmission electron microscopy (TEM). The results showed that esophageal epithelium was a single layer epithelium, which consisted of mucous cells and columnar cells. The esophageal glands were present in submucosa. The columnar cells were ciliated. According to the diverging ultrastructure of mucous vesicles, three types of mucous cells could be identified in the esophageal mucosa: i) electron-lucent vesicles mucous cell (ELV-MC); ii) electron-dense vesicles mucous cell (EDV-MC); and iii) mixed vesicles mucous cell (MV-MC).

    Ocular mucous membrane pemphigoid is an immunobullous disease in which excessive conjunctival fibrosis causes blindness, and the pathogenesis of scarring is incompletely understood. To establish whether profibrotic fibroblasts with an altered phenotype exist in ocular mucous membrane pemphigoid, we compared the functional characteristics of pemphigoid conjunctival fibroblasts to normal conjunctival fibroblasts with respect to cell division; migration; collagen contraction; matrix metalloproteinase, secretion of collagen and chemokines; and myofibroblast differentiation. We found that pemphigoid fibroblasts showed increased cell division (P = 0.01), increased migration in serum-free medium (72 ± 18 migrated cells versus 33 ± 11, P = 0.04), increased collagen contraction in the presence of 10 ng/ml tumor necrosis factor-α, increased collagen type I secretion (P = 0.03), increased secretion of matrix metalloproteinase-3 (P = 0.03), and increased secretion of eotaxin in response to interleukin-13 (P = 0.04). Differences between pemphigoid and normal conjunctival fibroblasts with respect to collagen contraction and MMP secretion in the presence of interleukin-13 were also observed. Together, these findings indicate that pemphigoid conjunctival fibroblasts have a profibrotic phenotype that is maintained in vitro. No differences between pemphigoid fibroblasts obtained from acutely inflamed versus clinically uninflamed conjunctiva were observed. Developing effective antifibrotic therapies will require understanding of the mechanisms that both induce and maintain the profibrotic phenotype. PMID:21224056

    We present 13 cases of oral mucous membrane pemphigoid (MMP) and review the literature. The cases were retrieved from the archives of Ondokuz Mayis University and Gülhane Military Medical Academy, Turkey, between 1997 and 2002. Inclusion criteria were clinical findings of oral MMP verified by histological and immunofluorescent examination. Thirteen patients (two males and 11 females), aged 16-72 years, were identified. Involvement was confined to the mouth in all cases except one, in which the conjunctiva was also affected. Two individuals in the study were < 20 years old, an age group rarely affected. The oral mucosa is often the initial site of MMP lesions, so it is important that dentists as well as physicians are aware of the symptoms and signs. A swift diagnosis, made in consultation with other specialists such as ophthalmologists and dermatologists, is needed in order to prevent a delay in treatment. PMID:12964512

We review the epidemiology of cervical radiculopathy and discuss the diagnosis of this condition. This includes an overview of the pertinent findings on the patient history and physical examination. We also discuss relevant clinical syndromes that must be considered in the differential diagnosis including peripheral nerve entrapment syndromes and shoulder pathology. The natural history of cervical radiculopathy is reviewed and options for management are discussed. These options include conservative management, non-operative modalities such as physical therapy, steroid injections, and operative intervention. While the exact indications for surgical intervention have not yet been elucidated, we provide an overview of the available literature regarding indications and discuss the timing of intervention. The surgical outcomes of anterior cervical decompression and fusion (ACDF), cervical disc arthroplasty (CDA), and posterior cervical foraminotomy (PCF) are discussed. PMID:27250042

    Full Text Available O papilomavírus humano (HPV é um fator etiológico bem estabelecido para o câncer cervical. Esse vírus de DNA infecta primariamente o epitélio e pode induzir lesões benignas ou malignas na pele e na mucosa. Alguns HPVs são considerados de alto risco, responsáveis pela progressão das lesões precursoras até câncer cervical. A infecção genital pelo HPV é comum em mulheres jovens e geralmente é transitória. Uma pequena proporção de mulheres infectadas desenvolve câncer cervical, implicando o envolvimento de fatores ambientais e fatores genéticos na carcinogênese. Essa revisão aborda a estrutura viral, classificação e patologia do HPV, história natural e fatores de risco para neoplasia cervical e perspectivas futuras com a vacina anti-HPV.Human papillomavirus (HPV has been established as an important etiological factor for the development of cervical cancer. This DNA virus primarily infects the epithelium and can induce benign and malignant lesions of the mucous membranes and skin. Some HPVs are considered high risk due to their role in malignant progression of cervical tumors. Genital HPV infections are common and usually transient among young sexually active women. Only a small fraction of infected women develop cervical cancer, implying the involvement of environmental and genetic cofactors in cervical carcinogenesis. Classification, virology, pathology, natural history, epidemiological features of genital HPV infection, and future prospects for cervical cancer prevention with HPV vaccines will be reviewed here.

    Full Text Available Although some morphological investigations on aged human sublingual glands (HSG found eventual phenomena identified as autolysis and mucous extravasation, the exact meaning of these findings has not been elucidated.Objective The aim of this work is to investigate whether acinar autolysis and mucous extravasation are related to the aging process in human sublingual glands. We also speculate if autolytic changes may assist forensic pathologists in determining time of death.Material and Methods 186 cadavers’ glands were allocated to age groups: I (0–30 years; II (31–60, and III (61–90. Time and mode of death were also recorded. Acinar autolysis and mucous extravasation were classified as present or absent. Ultrastructural analysis was performed using transmission electron microscopy (TEM. Data were compared using Mann-Whitney U, Spearman’s correlation coefficient, Kruskal-Wallis, and Dunn tests (p<0.05.Results There was correlation between age and acinar autolysis (r=0.38; p=0.0001. However, there was no correlation between autolysis and time of death. No differences were observed between genders. TEM showed mucous and serous cells presenting nuclear and membrane alterations and mucous cells were more susceptible to autolysis.Conclusion Acinar autolysis occurred in all age groups and increased with age while mucous extravasation was rarely found. Both findings are independent. Autolysis degrees in HSG could not be used to determine time of death.

  9. Histochemical and structural analysis of mucous glycoprotein secreted by the gill of Mytilus edulis

    International Nuclear Information System (INIS)

    Studies were carried out to characterized various mucous cells in the gill filament, to ascertain structural characteristics of the secreted mucous glycoproteins, and to determine the ability of the gill epithelium to incorporate [14C]glucosamine as a precursor in the biosynthesis and secretion of mucous glycoproteins. Using histochemical staining techniques, mucous cells containing neutral and acidic mucins were found in the lateral region, whereas mucous cells containing primarily neutral or sulfated mucins were found in the postlateral region. Serotonin, but not dopamine, stimulated the mucous secretion. In tissues pretreated with [14C]glucosamine, the secreted glycoproteins contain incorporated radiolabel. Analysis by column chromatography using Bio-Gel P-2 and P-6 shows that the secretion contains two glycoprotein populations. Glycoprotein II has a molecular weight of 2.3 x 104 daltons. Upon alkaline reductive borohydride cleavage of the O-glycosidic linkages of glycoprotein I, about 70% of the radiolabel was removed from the protein. Gas chromatographic analysis of the carbohydrate composition shows that the glycoproteins contains N-acetylglucosamine (GluNAc), N-acetylgalactosamine (GalNAc), and galactose, fucose and mannose. Amino acid analysis shows that the glycoproteins are rich in serine, threonine and proline

    2009-07-01

    Full Text Available Abstract Background The female lower genital tract is a gateway for pathogens entering the host through the mucous membrane. One of the prevalent human viruses is Torque teno virus (TTV. The major reported routes of TTV transmission are fecal-oral and parenteral. Furthermore, other modes of transmission, e.g. sexual contact, are suggested. To investigate the sexual route of TTV transmission, cervical smears of healthy women and those with cervical lesions were screened for the presence of TTV DNA. Methods TTV DNA was studied in cervical smears of 95 patients with cervical lesions and 55 healthy women. Paired serum samples were available from 55 and 42 women, respectively. All healthy women had normal cytology while 44 patients had histologically confirmed low-grade lesion (LGL and 51 high-grade lesion (HGL. TTV DNA was detected with primers specific for the non-coding region. In 40 paired cervical smears and serum samples, the phylogenetic group of TTV isolates was determined. The presence of HPV DNA in cervical smears was detected by means of PCR with MY09/11 primers. Results The prevalence of TTV DNA in cervical smears of healthy women was 52.7% and was comparable with that in paired serum samples (50%. Symptomatic women had significantly higher prevalence of TTV DNA in cervical smears (74.7% than healthy controls. The TTV DNA prevalence in patient serum samples was 51%. The phylogenetic groups of TTV serum isolates were concordant with those of TTV from cervical smears of the same subjects. In cervical smears, a wider variety of TTV isolates was found. The viral loads in cervical smears were 10 to 1000 times as high as in sera. The HPV-positive study subjects had significantly higher TTV DNA prevalence than HPV negatives. The prevalence of TTV was not associated with disease severity. Conclusion High prevalence of TTV in cervical smears suggests that sexual transmission is another mode of expansion of TTV infection among the population. The

    Finkbeiner, Walter E.; Zlock, Lorna T.; Mehdi, Irum

    2009-01-01

    There are two main epithelial cell types in the secretory tubules of mammalian glands: serous and mucous. The former is believed to secrete predominantly water and antimicrobials, the latter mucins. Primary cultures of human airway gland epithelium have been available for almost 20 yr, but they are poorly differentiated and lack clear features of either serous or mucous cells. In this study, by varying growth supports and media, we have produced cultures from human airway glands that in terms of their ultrastructure and secretory products resemble either mucous or serous cells. Of four types of porous-bottomed insert tested, polycarbonate filters (Transwells) most strongly promoted the mucous phenotype. Coupled with the addition of epidermal growth factor (EGF), this growth support produced “mucous” cells that contained the large electron-lucent granules characteristic of native mucous cells, but lacked the small electron-dense granules characteristic of serous cells. Furthermore, they showed high levels of mucin secretion and low levels of release of lactoferrin and lysozyme (markers of native serous cells). By contrast, growth on polyethylene terephthalate filters (Cyclopore) in medium lacking EGF produced “serous” cells in which small electron-dense granules replaced the electron-lucent ones, and the cells had high levels of lactoferrin and lysozyme but low levels of mucins. Measurements of transepithelial resistance and short-circuit current showed that both “serous” and “mucous” cell cultures possessed tight junctions, had become polarized, and were actively secreting Cl.

    Base materials, made on the basis of various derivatives of acrylic and methacrylic acids, have been widely used in prosthetic dentistry. Free monomer, affecting the tissues of prosthetic bed and the whole body, is always found in dentures. Therefore, study of the effect of acrylic resins' monomer on mucous membrane of the tongue is crucial. Rat tongue is very similar to human tongue, and this fact has become the basis for selecting these animals to be involved into the experiment. The paper presents the findings related to the effect of "Ftoraks" base acrylic resin monomer on the state of rat mucous membrane of the tongue and its regeneration. The microscopy has found that the greatest changes in the mucous membrane of the tongue occur on day 3 and 7 day after applying the monomer and are of erosive and inflammatory nature. Regeneration of tongue epithelium slows down. PMID:27119844

    Circulating and bound IgA antibodies can be found in the autoimmune blistering diseases, but their prevalence, clinical relevance and target antigens remain unknown. Thirty-two patients with pemphigus, 73 with bullous pemphigoid and 28 with mucous membrane pemphigoid were studied retrospectively. Direct immunofluorescence (DIF) analysis of IgG, IgA, IgM and C3 was carried out for all cases. Sera were studied by standard indirect immunofluorescence, indirect immunofluorescence on salt-split skin, immunoblotting for bullous pemphigoid and mucous membrane pemphigoid and ELISA for pemphigus. With DIF, we found IgA autoantibodies in 22 of all 133 cases. Circulating IgA antibodies to skin were detected in 2 of 3 IgA-DIF-positive patients with pemphigus, in 3 of 6 with bullous pemphigoid, and in 6 of 13 with mucous membrane pemphigoid. We confirm that the IgA reactivity is more frequently associated with mucous membrane involvement, especially in cases without critical involvement (5/8). The role of IgA and its antigenic specificity in these diseases remain unclear. PMID:15370705

    Full Text Available Abstract Background Worldwide cervical cancer remains a leading cause of mortality from gynecologic malignancies. The link between cervical cancer and persistent infection with HPV has been established. At a molecular level little is known about the transition from the precancerous state to invasive cancer. To elucidate this process, cervical biopsies from human specimens were obtained from precancerous state to stage III disease. Methods Cervical biopsies were obtained from patients with a diagnosis of cervical cancer undergoing definitive surgery or staging operation. Biopsies were obtained from patients with precancerous lesions at the time of their excisional procedure. Control samples were obtained from patients undergoing hysterectomy for benign conditions such as fibroids. Samples were subjected to proteomic profiling using two dimensional gel electrophoresis with subsequent trypsin digestion followed by MALDI-TOF protein identification. Candidate proteins were then further studied using western blotting, immunoprecipitation and immunohistochemistry. Results Annexin A1 and DNA-PKcs were found to be differentially expressed. Phosphorylated annexin A1 was up regulated in diseased states in comparison to control and its level was strongly detected in the serum of cervical cancer patients compared to controls. DNA-PKcs was noted to be hyperphosphorylated and fragmented in cancer when compared to controls. By immunohistochemistry annexin A1 was noted in the vascular environment in cancer and certain precancerous samples. Conclusion This study suggests a probable role for protein tyrosine phosphorylation in cervical carcinogenesis. Annexin A1 and DNA-PK cs may have synergistic effects with HPV infection. Precancerous lesions that may progress to cervical cancer may be differentiated from lesions that will not base on similar immunohistochemical profile to invasive squamous cell carcinoma.

    Children may be born with birth defects, the most common being oro-facial clefts and fissural cysts. A well circumscribed pedunculated soft tissue growth that occurs congenitally is known as congenital epulis of the newborn or ‘Neuman’s Tumour’ as described in the literature. It is a rare lesion and the diagnosis has to be confirmed histologically. We present a rare case of a 7-year-old child with a congenital growth in the pre-maxillary region of the anterior hard palate clinically diagnosed as congenital epulis however, histologically confirmed as a mucous retention cyst. An elaborate clinical differential diagnosis is discussed. The anterior hard palate is devoid of salivary glands and the presence of a mucous retention cyst in the area is suggestive of ectopic salivary gland tissue and in a child manifesting at birth is probably the first case to be reported in the English literature.

    A new technique for the stabilization of the mucous layers in the upper respiratory tree is described. The methodology combines perfusion of the thoracic vasculature through the carotid, thyroid, and bronchial arteries, with aerosolization of fixative onto the airway surface through a tracheostomy. The biphasic nature of the mucous layer in healthy animals is confirmed and is compared with the nature of the mucus in animals exposed to cigarette smoke. The fundamental advantage of the technique is that, because airway surface phenomena are stabilized, more thorough correlates of physiology and morphology can be accomplished. The intrapulmonary airways and parenchyma are also fixed by using this technique, and the results are discussed. A preliminary communication using this technique to document leukocyte transit across the respiratory mucosa has been published.

    Fingerlings of three freshwater fish species showed differences in susceptibility to lethality of 250 mg/L lead suspension or lead nitrate solution in water. Among these the large mouth bass Micropterus salmoides seemed to be more tolerant than green sunfish Lepomis cyanellus and goldfish Carassius auratus. Mucous from large mouth bass, when added to jars containing lead, lowered the toxicity of lead to sunfish and goldfish. Adding scales, especially if these were pretreated with an alkaline solution of cysteine and glycine, made all these species become tolerant to otherwise lethal concentrations of lead nitrate. The scales and mucous together buffered the acidity of lead nitrate and mercuric nitrate solution and sequestered hydrogen ions and lead and mercury from water and then settled to the bottom of jars. Scales of younger fingerling were more efficient than those of older ones.

    Full Text Available Introduction. In the second half of the last century skin tuberculosis has become a rarity. With the appearance of resistance to different kinds of pathogenes, HIV-immunodeficiency and decreasing standard of living, the incidence of skin tuberculosis increses. Lupus vulgaris is a chronic form of the secondary tuberculosis of the skin. Case report. This is a case report of a 66-year-old woman who presented with a growing, painless, brownish-red, slab-shaped, jelly, cutanesous mass, 2.5 centimeters in diameter, on the tip of her nose, reaching the mucous membrane of the nose. Results. Apart from accelerated erythrocyte sedimentation rate (43/73 and a positive tuberculosis test (Mantoux 10 TU=25x25 mm, all relevant findings were within reference values. Using Ziehl-Neelsen staining, no acido-resistent bacilli were found. The skin scraping sample, taken from the affected skin and the mucous membrane, was cultivated in Lowenstein medium base, and this resulted with cultivation of Mycobacterium tuberculosis. Using three-drug combination therapy for ten months, complete remission was achieved. Conclusion. Successful cultivation of pathogens represents an absolute diagnostic criterion. We present a case of a woman with lupus vulgaris, because there is a small number of cases documented around the world where the diagnosis was confirmed by culture of Mycobacterium tuberculosis. .

    2005-01-01

    Full Text Available Although anterior cervical instrumentation was initially used in cervical trauma, because of obvious benefits, indications for its use have been expanded over time to degenerative cases as well as tumor and infection of the cervical spine. Along with a threefold increase in incidence of cervical fusion surgery, implant designs have evolved over the last three decades. Observation of graft subsidence and phenomenon of stress shielding led to the development of the new generation dynamic anterior cervical plating systems. Anterior cervical plating does not conclusively improve clinical outcome of the patients, but certainly enhances the efficacy of autograft and allograft fusion and lessens the rate of pseudoarthrosis and kyphosis after multilevel discectomy and fusions. A review of biomechanics, surgical technique, indications, complications and results of various anterior cervical plating systems is presented here to enable clinicians to select the appropriate construct design.

  1. Study of the microflora of the cavity and the mucous membrane of the intestine in health and after gamma irradiation

    International Nuclear Information System (INIS)

    Microflora of the intestine of mice and guinea pigs have been studied before radiation and on the 3d and 7th days after gamma radiation in doses of 700 R and 450 R, respectively. Bifidobacteria and lactobacillia prevail quantitatively in microflora associated with mucous membrane of the intestine. A number of relatively pathogenic microorganisms are mainly in the cavity of large intestine and do not interact with mucous membrane. During the development of post-radiation dysbacteriosis of mice and guinea pigs all relatively pathogenic microorganism present in the large intestine cavity being actively reproducted disseminated small intestine and interact with mucous membrane, probably, invade into it. There appear Escherichia, Proteus, Clostridium, which have not been found in intact animals, in the intestine of irradiated guinea-pigs.

    In summarising the outcome of the present study it can be said spraying the agent on the oral mucous membrane once a day had an effect on the incidence of mucous membrane ulceration in the case of both placebo and dexpanthenol treatment. However, there was no significant difference between placebo and dexpanthenol treatment, the only finding being a slight prolongation of latency time through aloe vera. These experimental findings give good reason to critically reconsider the clinical use of dexpanthenol as a supportive treatment for the prevention of radiogenic mucositis enoralis following irradiation of tumours in the head and neck region. However thorough oral lavage is an effective means of moderating the irradiation response of the oral mucous membrane

    A total of 50 healthy persons and 50 chronic tonsillitis patients were examined with the use of the bacteriological method. The microflora of tonsillar mucous membrane was represented by 8 genera of facultative anaerobic microorganisms. In the biocenosis of the tonsillar mucosa of the healthy subjects the occurrence of Streptococcus was 1.5-fold greater than in that of the patients; microorganisms of the genus Staphylococcus prevailed on the tonsillar mucosa of chronic tonsillitis patients 1.3-fold prevailed more often and Klebsiella and Neisseria prevailed 4-fold more often. Among the microorganisms isolated from the patients, cultures simultaneously having two or more pathogenicity markers occurred twice as often as among the representatives of the microbiocenosis obtained from the healthy subjects. The microflora of the tonsillar mucosa of the chronic tonsillitis patients was characterized by resistance to penicillins, macrolides and aminoglygosides, but was simultaneously sensitive to lincosamides and glycopeptides.

    Lichen planus concerns a benign skin disorder without involvement of other organ systems. Its course is generally limited to less than a year. Classic lichen planus is characterized by pruritic, violaceous, plane papules which occur most commonly on the inside of the wrists, the lower back, the lower legs and the perimalleolar region of adults aged between 30-60 years. Frequently, oral and genital mucous membrane lesions are involved. Erosive mucosal lesions are particularly painful and long-lasting. Many clinical variants have been described ranging from lichenoid drug eruptions to associations with graft-versus-host disease. The cause of lichen planus is unknown. An immunopathological pathogenesis with T-lymphocytes directed against basal keratinocytes or the basal membrane zone is assumed. Multiple therapeutic options exist: local and systemic corticosteroids, psoralens with ultraviolet A light (PUVA), retinoids, cyclosporin. PMID:11675973

    Purpose: The mucous melanoma of superior aero-digestive tracts represents 1-2% of malignant melanomas, 5-10% of head and neck melanomas, and concerns particularly, the nasal cavities and naso-sinus cavities. The recurrences are frequent, often local ones, sometimes multifocal ones, the survival rate at five years is {<=} 30%. The Ballantyne classification distinguishes three stages: 1 localised tumors, 2 ganglions attack, 3 metastases. Are pejorative: a stage number 3 ( deep invasion, muscles, bones, cartilages) according to the Prasad classification (1: in situ or micro invasive, 2: invasion of the lamina propria), the achromia sub-type, a pseudo papillary or sarcoma, vascular emboli, necrosis. The recommendations rest on evidence level at 4. The complete excision is the rule and must be counterbalanced with the morbidity in case of orbital, dura-mater, frontal lobe, and infra temporal fossa. The adjuvant irradiation is debated.We evaluated the prognosis of mucous naso-sinus melanomas. Conclusion: The principal cause of death was the local failure. The Ballantyne classification does not take into account the extensions and overestimates the prognosis impact of ganglions invasion that is yet {<=}10% ( and does not justify a radiotherapy in lack of adenopathy). It underestimates probably the impact of adjuvant radiotherapy. One should be able to distinguish the unfavourable stage 1 tumors (receiving eventually a radiotherapy) and these ones of very localised stage 1 for which it could be omitted. The fractionation and the optimal dose remain to be defined. The volume {>=}100 ml and the irradiation by carbon ions seem promising in term of local control but the metastases stay a problem in the recent series. (N.C.)

    Apoptosis or programmed cell death is accompanied by characteristic morphological changes that distinguish apoptosis from other forms of cell death. These changes include DNA fragmentation, chromatin condensation, cell shrinkage, cell surface pseudopodia, and finally the cellular collapse into membrane-enclosed apoptotic bodies which are rapidly engulfed by macrophages or neighboring cells. Although the morphological features of apoptotic cells are well studied, the biochemical events that control apoptosis are not understood. Programmed cell death is triggered by a variety of pathways that are initiated by different stimuli including noxious agents, DNA damage, the activation of TNF receptors, or the withdrawl of growth factors. The central process of programmed cell death involves a cascade of biochemical events that begins with the initiation of a family of cysteine proteases, including the interleukin-1-{Beta}-converting enzyme, CPP-32, and Apopain. The ratio of Bax, a death-inducer gene, to Bcl-2, an apoptosis suppressor gene, determines whether or not the main apoptotic pathyway is blocked. Apoptosis is suppressed if the ratio of Bcl-2/Bax is > 1, and cells undergo apoptosis if the ratio is < 1. The overexpression of Bcl-2 has been shown to block the apoptotic program triggered by a variety of agents. Therefore, Bcl-2 must be involved in blocking the central pathway of the cell death program. In conclusion, this study showed that high levels of Bcl-2 were detected in some mucous cells at specific time points during mucous cell metaplasia, and this expression was reduced at later time points or was absent after remodeling of this epithelium.

  16. Proteomics Technologies and Challenges

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Proteomics is the study of proteins and their interactions in a cell. With the completion of the Human Genome Project, the emphasis is shifting to the protein compliment of the human organism. Because proteome reflects more accurately on the dynamic state of a cell, tissue, or organism, much is expected from proteomics to yield better disease markers for diagnosis and therapy monitoring. The advent of proteomics technologies for global detection and quantitation of proteins creates new opportunities and challenges for those seeking to gain greater understanding of diseases. High-throughput proteomics technologies combining with advanced bioinformatics are extensively used to identify molecular signatures of diseases based on protein pathways and signaling cascades. Mass spectrometry plays a vital role in proteomics and has become an indispensable tool for molecular and cellular biology. While the potential is great, many challenges and issues remain to be solved, such as mining low abundant proteins and integration of proteomics with genomics and metabolomics data. Nevertheless, proteomics is the foundation for constructing and extracting useful knowledge to biomedical research. In this review, a snapshot of contemporary issues in proteomics technologies is discussed.

    Full Text Available The Chinese giant salamander (Andrias davidianus, renowned as a living fossil, is the largest and longest-lived amphibian species in the world. Its skin is rich in collagens, and has developed mucous gland which could secrete a large amount of mucus under the scraping and electric stimulation. The molting is the degraded skin stratum corneum. To establish the functional skin proteome of Chinese giant salamander, two-dimensional gel electrophoresis (2DE and mass spectrometry (MS were applied to detect the composition and relative abundance of the proteins in the skin, mucus and molting. The determination of the general proteome in the skin can potentially serve as a foundation for future studies characterizing the skin proteomes from diseased salamander to provide molecular and mechanistic insights into various disease states and potential therapeutic interventions. Data presented here are also related to the research article “Proteomic analysis of the skin of Chinese giant salamander (Andrias davidianus” in the Journal of Proteomics [1].

    Animals have evolved many ways to enhance their own reproductive success. One bizarre sexual ritual is the "love" dart shooting of helicid snails, which has courted many theories regarding its precise function. Acting as a hypodermic needle, the dart transfers an allohormone that increases paternity success. Its precise physiological mechanism of action within the recipient snail is to close off the entrance to the sperm digestion organ via a contraction of the copulatory canal, thereby delaying the digestion of most donated sperm. In this study, we used the common garden snailCornu aspersumto identify the allohormone that is responsible for this physiological change in the female system of this simultaneous hermaphrodite. The love dart allohormone (LDA) was isolated from extracts derived from mucous glands that coat the dart before it is stabbed through the partner's body wall. We isolated LDA from extracts using bioassay-guided contractility measurement of the copulatory canal. LDA is encoded within a 235-amino acid precursor protein containing multiple cleavage sites that, when cleaved, releases multiple bioactive peptides. Synthetic LDA also stimulated copulatory canal contractility. Combined with our finding that the protein amino acid sequence resembles previously described molluscan buccalin precursors, this indicates that LDA is partially conserved in helicid snails and less in other molluscan species. In summary, our study provides the full identification of an allohormone that is hypodermically injected via a love dart. More importantly, our findings have important consequences for understanding reproductive biology and the evolution of alternative reproductive strategies. PMID:26817846

    Full Text Available According to Sir William Osler, Mouth is the mirror of the body which reflects systemic -diseases. The oral mucosa may be affected by a variety of mucocutaneous diseases and oral lesions may occur first or very early in several mucocutaneous disorders. The erosive gingival lesions associated with vesiculobullous diseases such as lichen planus, cicatricial pemphigoid, and pemphigus vulgaris have been collectively referred to as "Desquamative gingivitis" (DG. Gingival desquamation is a clinical sign in which the gingiva appears reddish, painful, glazed and friable with destruction of the epithelium. This gingival desquamation is due to various disease processes in gingiva. The disease process may be a localized disease of gingiva or a systemic disease which manifests in the gingiva. It is important to be aware of this rare clinical entity so as to distinguish DG from plaque induced gingivitis which is an extremely common condition, easily recognized and treated daily by the dental surgeon. Accurate diagnosis and effective treatment of these lesions may greatly diminish or reverse disease progression. Here by, we present a case of mucous membrane pemphigoid presenting as gingival desquamation in a 45 year old female. Our patient presented with generalized erythematous gingiva and gingival desquamation involving the free, attached and marginal gingiva of left maxillary and mandibular dentition. However, other mucosal and skin involvement was not appreciated in the present case. Thorough history, clinical examination, histopathology and immunofluorescence studies helped us to arrive at the diagnosis of this rare sub-epithelial blistering disorder.

    Full Text Available An 18-year-old woman was referred with late sequelae of chloroquine-induced Steven-Johnson syndrome. At the time of presentation, the symblepharon was involving the upper lids to almost the whole of the cornea, and part of the lower bulbar conjunctiva with the lower lid bilaterally. Other ocular examinations were not possible due to the symblepharon. B-scan ultrasonography revealed acoustically clear vitreous, normal chorioretinal thickness, and normal optic nerve head, with an attached retina. Conjunctivo-corneal adhesion released by superficial lamellar dissection of the cornea. Ocular surface reconstruction was carried out with a buccal mucous membrane. A bandage contact lens was placed over the cornea followed by the symblepharon ring to prevent further adhesion. The mucosal graft was well taken up along with corneal re-epithelization. Best corrected visual acuity of 20/120 in both sides after 1 month and 20/80 after 3 months was achieved and maintained till the 2.5-year follow-up.

    Full Text Available Exposure to cement dust has been associated with deleterious health effects in humans. This study investigated whether residing near a cement factory increases the risk of irritations to the mucous membranes of the eyes and respiratory system. A cross sectional study was conducted in Freedom Compound, a community bordering a cement factory in Chilanga, Zambia and a control community, Bauleni, located 18 km from the cement plant. A modified American Thoracic Society questionnaire was administered to 225 and 198 respondents aged 15–59 years from Freedom and Bauleni, respectively, to capture symptoms of the irritations. Respondents from Freedom Compound, were more likely to experience the irritations; adjusted ORs 2.50 (95% CI: 1.65, 3.79, 4.36 (95% CI (2.96, 6.55 and 1.94 (95% CI (1.19, 3.18 for eye, nose and sinus membrane irritations respectively. Cohort panel studies to determine associations of cement emissions to mucous membrane irritations and respiratory symptoms, coupled with field characterization of the exposure are needed to assess whether the excess prevalence of symptoms of mucous membrane irritations observed in Freedom compound are due to emissions from the cement factory.

  15. Local mucous membrane lesions caused by irradiation of the oropharynx can be prevented by a dental shield

    International Nuclear Information System (INIS)

    In patients with metallic dental fillings radiation therapy to the oral cavity can cause mucous membrane lesions, which are more severe than expected. They appear as circumscribed erosions, opposite to metallic fillings and are caused by an increase in radiation dose through secondary radiation due to the higher density and atomic number of the filling material. This dose increase can be directly measured with 0.1 mm thin sheets of graphite-loaded TLD's (LiF, Vinten). For Co-60 gamma rays a commercial amalgam filling caused a dose increase by a factor of 1.7. The half value layer for this additional radiation was measured to be approximately 0.4 mm tissue. In order to avoid painful mucous membrane ulcerations which are even more a problem if hyperfractionated treatment schedules are used, we constructed individual dental shields for each patient. As shielding material we used a dental impression material (Optosil P+, Bayer). This method was tested in 35 patients, in all of them circumscribed mucous membrane ulcerations could be avoided. The method proved to be fast and simple and was very well tolerated by all patients. (orig.)

    Marine bacterial strains were isolated from coastal regions of Goa and screened for the strains that produce the highest amount of mucous exopolysaccharide (EPS). Our screening resulted in the identification of the strain Vibrio furnissii VB0S3 (hereafter called VB0S3), as it produced the highest EPS in batch cultures during the late logarithmic growth phase. The isolate was identified as VB0S3 based on morphological and biochemical properties. Growth and EPS production were studied in mineral salts medium supplemented with NaCl (1.5%) and glucose (0.2%). The exopolymer was recovered from the culture supernatant by using three volumes of cold ethanol precipitation and dialysis procedure. Chemical analyses of EPS revealed that it is primarily composed of neutral sugars, uronic acids, and proteins. Fourier-transform infrared (FT-IR) spectroscopy revealed the presence of carboxyl, hydroxyl, and amide groups, which correspond to a typical heteropolymeric polysaccharide, and the EPS also possessed good emulsification activity. The gas chromatographic analysis of an alditol-acetate derivatized sample of EPS revealed that it was mainly composed of galactose and glucose. Minor components found were mannose, rhamnose, fucose, ribose, arabinose, and xylose. EPS was readily isolated from culture supernatants, which suggests that the EPS was a slime-like exopolysaccharide. This is the first report of exopolysaccharide characterization that describes the isolation and characterization of an EPS expressed by Vibrio furnissii strain VB0S3. The results of the study contribute significantly and go a long way towards an understanding of the correlation between growth and EPS production, chemical composition, and industrial applications of the exopolysaccharide in environmental biotechnology and bioremediation.

  17. Dietary Shifts May Trigger Dysbiosis and Mucous Stools in Giant Pandas (Ailuropoda melanoleuca)

    Dietary shifts can result in changes to the gastrointestinal tract (GIT) microbiota, leading to negative outcomes for the host, including inflammation. Giant pandas (Ailuropoda melanoleuca) are physiologically classified as carnivores; however, they consume an herbivorous diet with dramatic seasonal dietary shifts and episodes of chronic GIT distress with symptoms including abdominal pain, loss of appetite and the excretion of mucous stools (mucoids). These episodes adversely affect the overall nutritional and health status of giant pandas. Here, we examined the fecal microbiota of two giant pandas’ non-mucoid and mucoid stools and compared these to samples from a previous winter season that had historically few mucoid episodes. To identify the microbiota present, we isolated and sequenced the 16S rRNA using next-generation sequencing. Mucoids occurred following a seasonal feeding switch from predominately bamboo culm (stalk) to leaves. All fecal samples displayed low diversity and were dominated by bacteria in the phyla Firmicutes and to a lesser extent, Proteobacteria. Fecal samples immediately prior to mucoid episodes had lower microbial diversity as compared to mucoids. Mucoids were mostly comprised of common mucosal-associated taxa including Streptococcus and Leuconostoc species, and exhibited increased abundance for bacteria in the family Pasteurellaceae. Taken together, these findings indicate that mucoids may represent an expulsion of the mucosal lining that is driven by changes in diet. We suggest that these occurrences serve to reset their GIT microbiota following changes in bamboo part preference, as giant pandas have retained a carnivorous GIT anatomy while shifting to an herbivorous diet.

    Rowan, Fiachra

    2012-02-01

    OBJECTIVE: To optimize total bacterial 16S rRNA quantification in microdissected colonic crypts in healthy controls and patients with ulcerative colitis (UC) and to characterize the findings with disease activity. BACKGROUND: Microscopic and molecular techniques have recently converged to allow bacterial enumeration in remote anatomic locations [eg, crypt-associated mucous gel (CAMG)]. The aims of this study were to combine laser capture microdissection (LCM) and 16S rRNA-based quantitative polymerase chain reaction (qPCR) to determine total bacterial copy number in CAMG both in health and in UC and to characterize the findings with disease activity. METHODS: LCM was used to microdissect CAMG from colonic mucosal biopsies from controls (n = 20) and patients with acute (n = 10) or subacute (n = 10) UC. Pan-bacterial 16S rRNA copy number per millimeter square in samples from 6 locations across the large bowel was obtained by qPCR using Desulfovibrio desulfuricans as a reference strain. Copy numbers were correlated with the UC disease activity index (UCDAI) and the simple clinical colitis activity index (SCCAI). RESULTS: Bacterial colonization of CAMG was detectable in all groups. Copy numbers were significantly reduced in acute UC. In subacute colitis, there was a positive correlation between copy number and UCDAI and SCCAI in the ascending, transverse and sigmoid colon. CONCLUSIONS: This study describes a sensitive method of quantitatively assessing bacterial colonization of the colonic CAMG. A positive correlation was found between CAMG bacterial load and subacute disease activity in UC, whereas detectable bacterial load was reduced in acute UC.

    Full Text Available Purpose: The aim of this study is to foreseen the influence of elastomers on the development of mucous-borne dentures in the aspect of bio-compatible use of prosthetic foundation tissue load bearing capacity.Design/methodology/approach: Multi-criteria comparative analysis based on the dendrological matrix of attractiveness and potential was used for the studies of denture solution and materials. There were differentiated seven groups of conventional dentures without an implantological stabilisation - the so-called hard dentures (CD and those with a soft relining (CD-P, stabilized on one implant (SID or on two implants (TID, that were differentiated as far as the denture attachment to implant was concerned. The first group was marked as „hard” (K due to the used materials and inconsiderable lateral compliance. The elastomeric attachments (S constituted the second group of attachments.Findings: In case of conventional dentures a significant influence of the relining on attractiveness was observed. In case of dentures retained on elastomeric attachments – they decided not only on the attractiveness, but they have also significantly increased dentures’ potential.Research limitations/implications: Throughout the studies the variation of denture bearing structure materials were not taken into account, based on the assumption that acrylates are the most commonly used.Practical implications: The similar level of attractiveness of dentures retained on implants significantly varying as far as their construction is concerned shows that the focus should be mainly put on material design of elastomers’ wearing characteristics.Originality/value: Multi-criteria heuristic analysis proved to be an effective tool for examination of dentures in the aspect evaluation of dentures material and cosntruction that show perspectives of the broadest use due to exploitation of the tissue bearing capability.

    This study presents protective mechanism of the mucous membrane with our main emphasis on mucopolysaccharides within the mucous membrane at varying stages of gastric ulcer. If we look at the findings based on 35SO4 autoradiography, an increase in uptake of 35SO4 by the epithelial cells of the active stage (A2) and a peak is exhibited during the initial half of the healing stage (H1). If the amount of hexosamine within the mucous membrane is determined, a movement similar to the 35SO4 autoradiographic findings is exhibited with a peak occurring from the A2 to the H1 stage. In summary, it is conceivable that based on the mucopolysaccharide metabolism during the varying stages of gastric ulcer, formation of a mucous barrier is quite rapidly initiated after ulceration and the importance of a protective factor in healing process of gastric ulcer is suggested.

    Full Text Available Fibroids are benign (non-cancerous growths on the uterus. There is an overall incidence of 20% in women more than 30yrs of age. The incidence of cervical fibroids is much lower at 1-2%. An unmarried girl presented with complaints of difficulty in passing urine, lower abdominal pain and spasmodic dysmenorrhea for 4 months. Per abdomen there was a firm, non-tender midline mass arising from the pelvis corresponding to 20 weeks size gravid uterus with restricted mobility. Cervix could not be felt. Ultrasonographic examination showed 10.2x10.7 cm fibroid in the posterior wall with no adnexal pathology and bilateral mild hydronephrosis. On laparotomy, the uterus was found to be sitting like a lantern on the dome of St. Paul's Cathedral. A 25x18 cm pseudo central cervical fibroid, partly intramural, partly sub mucous was seen to arise from the posterior cervico isthmic region. Myomectomy was performed successfully. Central cervical fibroid expands the cervix equally in all directions and the uterus is elevated on top of the large tumor. Diagnosis is by ultrasonogram and HSG. Management in cervical fibroid of supravaginal portion is hysterectomy if fertility is not desired and myomectomy if the patient is young and fertility is desired, as in our case.

    Full Text Available Foregut duplication is commonly found in the posterior mediastinum. 10-20% of these anomalies are associated with oesophageal duplication. It can occur in all parts of oesophageal length. Although duplication of cervical oesophagus has been previously reported, but a majority of them were found in thoracic oesophagus. Infants with oesophageal duplication usually manifested by respiratory distress or asymptomatic thoracic mass, casually, detected in X-ray. A 7-month-old infant weighing about 7.5 kg, with the signboard of respiratory distress, fever and nutritional intolerance was admitted to our hospital. Physical examination showed dehydration, stridor, tachypnoea, intercostal retraction and neck stiffness. Plain chest radiogram showed dubious cystic mass in the distal neck. Cervical and chest computed tomography scan showed neck cystic lesion disseminated to posterior mediastinum, probably propagated to the respiratory system. Cystic lesion connected to oesophagus was partially resected, oesophagus was repaired and remaining mucous of a cyst was removed, then gastrostomy tube was applied. Although cervical oesophageal duplication cysts are rare, but they must be considered as one of the differential diagnoses of cervical mass with respiratory distress in infants.

    Imaging techniques provide excellent anatomical images of the cervical spine. The choice to use one technique or another will depend on the clinical scenario and on the treatment options. Plain-film X-rays continue to be fundamental, because they make it possible to evaluate the alignment and bone changes; they are also useful for follow-up after treatment. The better contrast resolution provided by magnetic resonance imaging makes it possible to evaluate the soft tissues, including the intervertebral discs, ligaments, bone marrow, and spinal cord. The role of computed tomography in the study of degenerative disease has changed in recent years owing to its great spatial resolution and its capacity to depict osseous components. In this article, we will review the anatomy and biomechanical characteristics of the cervical spine, and then we provide a more detailed discussion of the degenerative diseases that can affect the cervical spine and their clinical management.

    Full Text Available Cervical necrotizing fasciitis is an unusual encounter in the general surgical practice, but is a life-threatening condition requiring early recognition and adequate surgical treatment. We present the case of a 65 year old male patient referred to our department from a General Hospital. Large excisions of both superficial and deep cervical fascia were required together with necrotic skin on a very large surface. Rapid recovery with early sterilization allowed adequate skin grafting with good results. We advocate for aggressive debridment with excision in viable healthy tissue, with no concern for the future reconstruction followe by early grafting of the skin defect.

    The present study was designed to examine the effects of long-term ozone exposure on nasal epithelia and intraepithelial mucosubstances (IM) throughout the nasal airways of F344/N rats. Animals were exposed to 0 (controls). 0. 12. 0.5, or 1.0 ppm ozone. 6 h/day, 5 days/wk. for 20 mo. Rats were killed 1 wk after the end of the exposure. and nasal tissues were processed for light and electron microscopy. Standard morphometric techniques were used to determine epithelial cell densities and the amounts of IM in the surface epithelium lining the nasal airways. No mucous cells or IM were present in the epithelia lining the nasal lateral meatus and maxillary sinus of rats exposed to 0 or 0.12 ppm ozone. In contrast, rats exposed to 0.5 or 1.0 ppm ozone had marked mucous cell metaplasia (MCM) with numerous mucous cells and conspicuous amounts of IM in the surface epithelium lining these upper airways. Ozone-induced increases in total epithelial cells (i.e., epithelial hyperplasia) were present only in rats exposed to 1.0 ppm. The results of this study indicate that rats chronically exposed to 1.0 or 0.5 ppm, but not 0. 121 ppm. ozone can develop marked MCM with significant increases in IM in both proximal and distal nasal airways. The epithelial chances observed throughout the nasal passages of ozone-exposed rats may be adaptive responses in an attempt to protect the upper and lower respiratory tract from further ozone-induced injury.

    Proteomics analyses enable the identification and quantitation of proteins. From a purely clinical perspective, the application of proteomics based on innovations, may greatly affect the future management of malignant brain tumors. This optimism is based on four main reasons: diagnosis, prognosis, selection of targeted therapy based on molecular profile of the brain tumor and monitoring therapeutic response, or resistance. We extracted the proteins of tumor and normal brain tissues, and then evaluated the protein purity by Bradford test. In this study, we separated the proteins by two-dimensional (2DG) gel electrophoresis methods. Then spots were analyzed, compared using statistical data and specific software and were identified by pH isoelectric, molecular weights and data banks. The protein profiles were determined using 2D gel electrophoresis and MALDI TOF/TOF mass spectrometry approaches. Simple statistical tests were used to establish a putative hierarchy in which the change in protein level was ranked according to a cut-off point with pProteomics is a powerful way to identifying multiple proteins which are altered following a neuropharmacological intervention in a CNS disease.

  16. Proteomics - new analytical approaches

    International Nuclear Information System (INIS)

    Full text: Recent developments in the sequencing of the human genome have indicated that the number of coding gene sequences may be as few as 30,000. It is clear, however, that the complexity of the human species is dependent on the much greater diversity of the corresponding protein complement. Estimates of the diversity (discrete protein species) of the human proteome range from 200,000 to 300,000 at the lower end to 2,000,000 to 3,000,000 at the high end. In addition, proteomics (the study of the protein complement to the genome) has been subdivided into two main approaches. Global proteomics refers to a high throughput examination of the full protein set present in a cell under a given environmental condition. Focused proteomics refers to a more detailed study of a restricted set of proteins that are related to a specified biochemical pathway or subcellular structure. While many of the advances in proteomics will be based on the sequencing of the human genome, de novo characterization of protein microheterogeneity (glycosylation, phosphorylation and sulfation as well as the incorporation of lipid components) will be required in disease studies. To characterize these modifications it is necessary to digest the protein mixture with an enzyme to produce the corresponding mixture of peptides. In a process analogous to sequencing of the genome, shot-gun sequencing of the proteome is based on the characterization of the key fragments produced by such a digest. Thus, a glycopeptide and hence a specific glycosylation motif will be identified by a unique mass and then a diagnostic MS/MS spectrum. Mass spectrometry will be the preferred detector in these applications because of the unparalleled information content provided by one or more dimensions of mass measurement. In addition, highly efficient separation processes are an absolute requirement for advanced proteomic studies. For example, a combination of the orthogonal approaches, HPLC and HPCE, can be very powerful

  1. Enzymatic sulfation of gastric mucous glycoprotein in rat--changes in glycoprotein sulfotransferase activity with stress and anti-ulcer agent, sofalcone

    International Nuclear Information System (INIS)

    Enzymatic sulfation of mucous glycoprotein (GP) was studied in gastric mucosa of rat. After rat stomach was incubated with [35S]-sulfate, incorporation of radioactivity into gastric mucosal APS (adenosine 5'-phosphosulfate), PAPS (3'-phosphoadenosine 5'-phosphosulfate) and endogenous GPs could be detected. The degree of sulfation of endogenous GPs was highest in the macromolecular GP (peak I) and lowest in the low molecular GP (peak III). By using a crude preparation of GP sulfotransferase from rat gastric mucosa, the transfer of [35S]-sulfate from [35S]-PAPS into macromolecular mucous GP was determined as being the activity of sulfotransferase. The activity of GP sulfotransferase was mainly distributed in the microsomal fraction, and was proportional to the incubation time, substrate (mucous GP) concentration and [35S]-PAPS concentration. The enzyme activity was significantly higher in the corpus than that in the antral mucosa. The activity of GP sulfotransferase was significantly decreased at 6 h and was significantly increased at 12 h after the stress load, compared with that of the non-stressed condition. Anti-ulcer agent, sofalcone, increased the GP sulfotransferase activity under the stressed condition. On the other hand, cimetidine showed a significant inhibitory effect under the same condition. Changes in the GP sulfotransferase activity with stress and anti-ulcer agents were consistent with those in the incorporation of [35S]-sulfate into macromolecular mucous GP. These results suggest the importance of GP sulfotransferase as a key enzyme regulating the sulfation of mucous GP

    Mucous membrane pemphigoid (MMP) is a subtype of autoimmune subepidermal blistering diseases characterized by autoantibodies to structural components of the hemidesmosome primarily affecting mucous membranes. Inflammation-related progressive scarring can lead to serious complications, including blindness, and the disease may be associated with malignancy. Conventional immunosuppressive treatment is often insufficiently effective and limited due to side effects, warranting new therapeutic options ideally targeting both inflammation and extensively recalcitrant cicatrization. Heat shock protein 90 (Hsp90) is a cell stress-inducible chaperone required for the function of a large number of client proteins, and its pharmacological inhibition has proven to be effective and relatively safe in patients with cancer. Recent observations also suggest a promising role of Hsp90 as drug target in preclinical in vivo murine models of autoimmune diseases such as subepidermal bullous and fibrotic autoimmune disorders comprising epidermolysis bullosa acquisita and systemic sclerosis, respectively, which exhibit some pathophysiological features reminiscent of MMP. This article thus hypothesizes that Hsp90 blockade could represent a double-edged sword in MMP treatment by targeting pathogenic factors of inflammatory blister and fibrosis formation. Moreover, Hsp90 inhibitors could even be proclaimed as a triple-edged sword in case of an underlying malignancy. Future studies investigating the role of Hsp90 in MMP are needed to clarify whether Hsp90 inhibition could become a novel treatment approach for patients with this potentially devastating disease.

    Mass spectrometry (MS)-based high-throughput proteomics is the core technique for large-scale protein characterization. Due to the extreme complexity of proteomes, sophisticated separation techniques and advanced MS instrumentation have been developed to extend coverage and enhance dynamic range and sensitivity. In this review, we discuss the separation and prefractionation techniques applied for large-scale analysis in both bottom-up (i.e., peptide-level) and top-down (i.e., protein-level) proteomics. Different approaches for quantifying peptides or intact proteins, including label-free and stable-isotope-labeling strategies, are also discussed. In addition, we present a brief overview of different types of mass analyzers and fragmentation techniques as well as selected emerging techniques.

    Uveal melanoma is the most common primary intraocular malignancy in adults, with an incidence of 5-7 per million per year. It is associated with the development of metastasis in about 50% of cases, and 40% of patients with uveal melanoma die of metastatic disease despite successful treatment of the primary tumour. The survival rates at 5, 10 and 15 years are 65%, 50% and 45% respectively. Unlike progress made in many other areas of cancer, uveal melanoma is still poorly understood and survival rates have remained similar over the past 25 years. Recently, advances made in molecular genetics have improved our understanding of this disease and stratification of patients into low risk and high risk for developing metastasis. However, only a limited number of studies have been performed using proteomic methods. This review will give an overview of various proteomic technologies currently employed in life sciences research, and discuss proteomic studies of uveal melanoma.

  5. Establishing Substantial Equivalence: Proteomics

    Lovegrove, Alison; Salt, Louise; Shewry, Peter R.

    Wheat is a major crop in world agriculture and is consumed after processing into a range of food products. It is therefore of great importance to determine the consequences (intended and unintended) of transgenesis in wheat and whether genetically modified lines are substantially equivalent to those produced by conventional plant breeding. Proteomic analysis is one of several approaches which can be used to address these questions. Two-dimensional PAGE (2D PAGE) remains the most widely available method for proteomic analysis, but is notoriously difficult to reproduce between laboratories. We therefore describe methods which have been developed as standard operating procedures in our laboratory to ensure the reproducibility of proteomic analyses of wheat using 2D PAGE analysis of grain proteins.

    Full Text Available Insect innate immunity is both a model for vertebrate immunity as well as a key system that impactsmedically important pathogens that are transmitted by insects. Recent developments in proteomics andprotein identification techniques combined with the completion of genome sequences for Anophelesgambiae and Drosophila melanogaster provided the tools for examining insect immunity at a new level ofmolecular detail. Application of proteomics to insect immunity resulted in predictions of new roles inimmunity for proteins already known in other contexts (e.g. ferritin, transferrin, Chi-lectins and helped totarget specific members of multi-gene families that respond to different pathogens (e.g. serine proteases,thioester proteins. In addition, proteomics studies verify that post-translational modifications play a keyrole in insect immunity since many of the identified proteins are modified in some way. These studiescomplement recent work on insect transcriptomes and provide new directions for further investigation ofinnate immunity.

    Full Text Available Objectives: Squamous cell carcinoma (SCC is the most common oral malignancy, and verrucous carcinoma (VC is a less invasive type of SCC. Leukoplakia (LP is the most frequent premalignant lesion in the oral cavity. The human papillomavirus (HPV has been recognized as one of the etiologic factors of these conditions. The association of anogenital and cervical cancers with HPV particularly its high-risk subtypes (HPV HR has been demonstrated. The purpose of our study was to investigate the hypothetical association between HPV and the mentioned oral cavity lesions.  Methods: One hundred and seventy-three samples (114 SCCs, 21 VCs, 20 LPs and 18 normal mucosa samples (as a control group were retrieved from the Department of Oral and Maxillofacial Pathology of Mashhad Dental School, Iran. The association of HPV genotypes in LP, VC, and SCC was compared to normal oral mucosa using the polymerase chain reaction.  Results: The results showed the absence of HPV in normal mucosa and LP lesions. In three samples of VC (14.3%, we observed the presence of HPV HR (types 16 and 18. All VCs were present in the mandibular ridge of females aged over 65 years old. No statistically significant correlation between HPV and VC was observed (p=0.230. Additionally, 15 (13.1% SCCs showed HPV positivity, but this was not significant (p=0.830. The prevalence of SCC was higher on the tongue with the dominant presence of less carcinogenic species of HPV (types 6 and 11. A statistically significant association was not observed between HPV and SCC or VC in the oral cavity.  Conclusions: More studies are necessary to better understand the relationship between HPV and malignant/premalignant oral cavity lesions.

    2016-09-01

    Cervical myelopathy is the most common cause of acquired spinal cord compromise. The concept of degenerative cervical myelopathy (DCM), defined as symptomatic myelopathy associated with degenerative arthropathic changes in the spine axis, is being introduced. Given its progressive nature, treatment options have to be chosen in a timely manner. Surgical options include anterior discectomy and fusion (ACDF), anterior corpectomy and fusion (ACCF), arthroplasty (in highly select cases), posterior laminectomy with/without fusion, and laminoplasty. Indications for each should be carefully considered in individual patients. Riluzole, a sodium-glutamate antagonist, is a promising option to optimize neurologic outcomes post-surgery and is being examined in the CSM-Protect Randomized Controlled Trial. Preoperative risk assessment is mandatory for prognostication. Sagittal alignment is known to play an important role to optimize surgical outcome. Guidelines for optimal management of DCM are in process. In principle, all but the mildest cases of DCM should be offered surgery for optimal outcome. PMID:27250040

    Biologists are awash with genomic sequence data. In large part, this is due to the rapid acceleration in the generation of DNA sequence that occurred as public and private research institutes raced to sequence the human genome. In parallel with the large human genome effort, mostly smaller genomes of other important model organisms were sequenced. Projects following on these initial efforts have made use of technological advances and the DNA sequencing infrastructure that was built for the human and other organism genome projects. As a result, the genome sequences of many organisms are available in high quality draft form. While in many ways this is good news, there are limitations to the biological insights that can be gleaned from DNA sequences alone; genome sequences offer only a bird's eye view of the biological processes endemic to an organism or community. Fortunately, the genome sequences now being produced at such a high rate can serve as the foundation for other global experimental platforms such as proteomics. Proteomic methods offer a snapshot of the proteins present at a point in time for a given biological sample. Current global proteomics methods combine enzymatic digestion, separations, mass spectrometry and database searching for peptide identification. One key aspect of proteomics is the prediction of peptide sequences from mass spectrometry data. Global proteomic analysis uses computational matching of experimental mass spectra with predicted spectra based on databases of gene models that are often generated computationally. Thus, the quality of gene models predicted from a genome sequence is crucial in the generation of high quality peptide identifications. Once peptides are identified they can be assigned to their parent protein. Proteins identified as expressed in a given experiment are most useful when compared to other expressed proteins in a larger biological context or biochemical pathway. In this chapter we will discuss the automatic

    Treatment-requiring diseases of the cervical spine in children are rare. The most common cases requiring medical assessment and treatment are acute torticollis and various accidents. A torticollis having lasted for more than a week should be recognized, because it can be treated by skull traction. Cervical spine fractures in children under school age are very rare, the most common being a fracture of the base of the dens of the second cervical vertebra. Cervical spine instability is almost always associated with an underlying disease. PMID:27400588

  20. Investigations of the dependence of radiation effects on the stem cells of the small intestine mucous membrane on dose fractionation

    International Nuclear Information System (INIS)

    For the study of the dependence of the radiation effects on the stem cells of the small intestine mucous membrane on dose fractionation mice from the strain C3H were exposed to a one-time irradiation, an irradiation in three fractions, five fractions on one day, five fractions on two days and an irradiation in ten fractions. It was shown, that the survival curves for the higher fractionation numbers were shifted to the right from the ones with higher total doses and have a lower slope than the curves lying more to the left. The accumulation of a total dose for an iso-effect is not proportional to the increase in the number of fractions, but instead in the area above 5 fractions reaches a plateau. The survival curve of the one-time dose which I constructed in the shoulder area showed a strong agreement with the survival curve which was given by Withers and Hussey. (orig.)

    Full Text Available Mucous membrane pemphigoid (MMP is an autoimmune mucocutaneous blistering disease characterized by autoantibodies to components within the basement membrane zone. The lesions may produce risk of scarring of the cants (symblepharon, inversion of the eyelashes (entropion and trauma to the cornea (trichiasis. We reported a case of MMP in a 56-year old female with controlled diabetes mellitus and hypertension whose ocular involvement has lead to blindness of the right eye. The diagnosis of MMP was based on the history and clinical findings in oral medicine department. Management of this patient included the administration of anti-fungal, corticosteroid, diaminodiphenylsulfone, nutritional supplementation oral hygiene promotion and consultation to internal medicine specialist and ophtalmologist. The improvement of oral lesions progressed well within five months. We conclude that optimal improvement can be reached by comprehensive management with controlling systemic factor and good cooperation between medical team and patient.

    . All workers were washing hands with soap in both the processes. 48.48% and 90.52% of the workers were using hand gloves in the sodium dichromate manufacturing and chrome plating industry, respectively. Only 27.27% and 37.50% of the workers were using masks in the sodium dichromate manufacturing industry and chrome plating industry, respectively. No worker was using protective clothing or barrier cream in the sodium dichromate manufacturing industry. 40.65% and 12.50% workers were using protective clothing and barrier cream in the chrome plating industry. Conclusion: Workers engaged in sodium dichromate manufacturing and chrome plating are at a great risk of skin and mucous membrane disorders including chrome holes and nasal septum perforation. Protective measures and awareness of the management and workers about the exposure hazards and safeguarding against them will be useful public measures to prevent these occupational hazards among workers engaged in these processes.

    Pyruvate kinase M2 (PKM2) is a key driver of aerobic glycolysis in cancer cells and has been shown to be up-regulated by mTOR in vitro. Our previous proteomic profiling studies showed that PKM2 was significantly upregulated in cervical cancer tissues after treatment with neoadjuvant chemotherapy (NACT). Whether PKM2 expression predicts cisplatin-based NACT sensitivity and is mTOR dependent in cervical cancer patients remains unclear. Using paired tumor samples (pre- and post-chemotherapy) from 36 cervical cancer patients, we examined mTOR, HIF-1α, c-Myc, and PKM2 expression in cervical cancer samples and investigated the response to cisplatin-based NACT. In addition, we established PKM2 suppressed cervical cancer cell lines and evaluated their sensitivity to cisplatin in vitro. We found that the mTOR/HIF-1α/c-Myc/PKM2 signaling pathway was significantly downregulated in post-chemotherapy cervical cancer tissues. High levels of mTOR, HIF-1α, c-Myc, and PKM2 were associated with a positive chemotherapy response in cervical cancer patients treated with cisplatin-based NACT. In vitro, PKM2 knockdown desensitized cervical cancer cells to cisplatin. Moreover, PKM2 had complex interactions with mTOR pathways. mTOR, HIF1α, c-Myc, and PKM2 expression in cervical cancer may serve as predictive biomarkers to cisplatin-based chemotherapy. PKM2 enhances chemosensitivity to cisplatin through interaction with the mTOR pathway in cervical cancer. PMID:27492148

    International Nuclear Information System (INIS)

    Glioblastoma multiforme (GBM) is the most common and most malignant primary brain tumour in adults. In spite of the hostile nature of glioblastoma multiforme (GBM), extracranial spread is not a common event. With improving management choices and survival times, reports of extracranial occurrence of GBM have increased. Most commonly these metastases are to the lungs, lymph nodes, neck, skull, scalp, liver, and bones; may be evident on routine follow-up images of the original lesion. Head and neck metastasis of GBM can be debilitating. We present a case of cervical metastasis of GBM and discuss possible mechanisms of extraneural spread of this tumour. (author)

    Curative-intent radical radiotherapy of cervical cancer consists of external-beam radiotherapy, brachytherapy, and concomitant chemotherapy with cisplatin. For each element, new developments aim to improve tumor control rates or treatment tolerance. Intensity-modulated radiotherapy (IMRT) has been shown to reduce gastrointestinal toxicity and can be used to selectively increase the radiotherapy dose. Individualized, image-guided brachytherapy enables better adaptation of high-dose volumes to the tumor extension. Intensification of concomitant or sequential systemic therapy is under evaluation.

    Monoclonal antibodies such as bevacizumab are widely used in medical oncology, either alone or in combination with chemotherapy. No specific recommendations on the management of monoclonal antibodies extravasation exist. Incidence rates vary considerably. Estimates of 0.5-6% have been reported in the literature. Also, patient-associated and procedure-associated risk factors of extravasation are multiple, such as bolus injections or poorly implanted central venous access. We report on an 86-year-old woman with colon cancer with liver metastasis who was treated with 5-fluorouracil, folinic acid, and bevacizumab. Extravasation occurred during chemotherapy infusion because of a catheter migration of the port outside of the superior vena cava, causing cervical pain without skin modifications. Diagnosis was confirmed with the appearance of clinical right cervical tumefaction and cervicothoracic computed tomography scan indicated a perijugular hypodense collection, corresponding to the extravasation. Conservative management was proposed. The patient recovered within 3 weeks from all symptoms. Physicians should be aware that in cases of bevacizumab extravasation, a nonsurgical approach might be effective. PMID:23262983

    Keegan (1965) reported a patient who presented with "dissociated motor loss," an acute paralysis of the upper extremity with minimal sensory signs and no long tract signs, and documented an anterior root lesion following autopsy. Sobue et al. (1975) reported similar cases using the term "cervical spondylotic amyotrophy (CSA)," but postulated pathology of the anterior horn. Although Keegan's "dissociated motor loss" surely referred to isolated motor paresis with no or minimal sensory signs, contrary to existing criticism, a more general term, CSA, should be preferred. CSA is divided into proximal and distal types. Distal CSA often presents with a drop finger, and thus may be misdiagnosed as posterior interosseous nerve palsy. Documentation of the involvement of ulnar muscles by clinical signs and EMG would lead to the diagnosis of distal CSA. Proximal CSA may be confused with neuralgic amyotrophy (NA), although the sparing of the serratus anterior and the stereotypic involvement of deltoid, infraspinatus, biceps brachii, and brachioradialis suggest CSA. Cervical MRI is not diagnostic in around half of CSA cases, and denervation in paraspinal EMG is a more sensitive test that can exclude NA. Amyotrophic lateral sclerosis is another important differential diagnosis for CSA. PMID:27156504

    Full Text Available Cervical spondylosis is a common, chronic degenerative condition of the cervical spine that affects the vertebral bodies and intervertebral disks of the neck as well as the contents of the spinal canal. Common clinical syndromes associated with cervical spondylosis include cervical pain, cervical radiculopathy and/or mielopathy. This study show the main principles, indication and side effects of tuina in cervical spondylosis´ treatment; tuina is one of the external methods based on the principles of Traditional Chinese Medicine (TCM, especially suitable for use on the elderly population and on infants. While performing Tuina, the therapist concentrates his mind, regulates his breathing, and actuates the Qi and power of his entire body towards his hands. For a better result is recommended to try to combine acupuncture with tuina treatment. Tuina can help relieve the pain associated with spondylosis. After this kind of treatment, the symptomes produced by irritated nerves and sore muscles can find some relief. Tuina helps patients with cervical spondylosis regain muscle control, nerve function and flexibility, all through the restoration of the life force flow.

    Objective: The role of human papillomavirus (HPV) in the development of cervical carcinoma has been clearly established but other factors could be involved in cervical tumorigenesis such as loss of heterozygosity (LOH) and microsatellite instability (MI). The aim of the present study was to investigate the genetic instability in cervical carcinoma tissues and provide evidence for discoveringnew tumor suppressor genes and screening diagnostic molecular marker of cervical carcinoma. Methods: Fifty primary cervical carcinoma samples from high-incidence area were analyzed by PCR for HPV16 infection, LOH and microsatellite instability. Results: HPV16 was detected in 88% of the cases. Sixty-six percent of total cases showed LOH with no more than 3 different loci per case. The highest frequency of the allelic loss was found in D18S474 (18q21, 40.5%). MI was detected in 4 cases (8%) only. Conclusion: Different percentages of LOH on specific chromosomal regions were found and MI was very infrequent in cervical carcinoma. The putative suppressor gene(s) could be located on specific chromosome regions such as 18q, and genetic instability could be involved in cervical tumorigenesis.

    After a successful completion of the Human Genome Project, deciphering the mystery surrounding the human proteome posed a major challenge. Despite not being largely involved in the Human Genome Project, the Indian scientific community contributed towards proteomic research along with the global community. Currently, more than 76 research/academic institutes and nearly 145 research labs are involved in core proteomic research across India. The Indian researchers have been major contributors in drafting the "human proteome map" along with international efforts. In addition to this, virtual proteomics labs, proteomics courses and remote triggered proteomics labs have helped to overcome the limitations of proteomics education posed due to expensive lab infrastructure. The establishment of Proteomics Society, India (PSI) has created a platform for the Indian proteomic researchers to share ideas, research collaborations and conduct annual conferences and workshops. Indian proteomic research is really moving forward with the global proteomics community in a quest to solve the mysteries of proteomics. A draft map of the human proteome enhances the enthusiasm among intellectuals to promote proteomic research in India to the world.This article is part of a Special Issue entitled: Proteomics in India.

    A total of 250 patients with diagnosed bronchial asthma (BA) were examined by microbiological methods. Among them--188 children and 62 adults. In 87 patients the microflora of nasal mucosa was studied, in 40--of pharynx only and in 123 patients--both the nasal and the pharynx. For comparative analysis earlier data obtained in 69 patients with persistent allergic rhinitis (PAR) were used. The cultures isolated from the nasal mucosa of BA patients were shown to number 18 genera and 42 species, while among those isolated from pharynx mucosa 20 genera and 40 species. Monocultures were isolated from the nasal mucosa only in 23% of the examined patients and from the pharynx mucosa--only in 1.42%. Associations with different numbers of components were isolated from nasal and pharynx mucosa (2 to 6, 2 to 8 respectively). Staphylococcus aureus was regarded as the main species of nasal biocenosis in BA and PAR, as well as pharynx biocenosis in BA. Besides, in BA other Staphylococcus species (schleiferi, caprae, capitis, hominis, etc.), reversely related to the main species, could be isolated from both mucous membranes. Similarities and differences in microflora of biocenoses in both nosological forms, confirming links between PAR and BA, are considered. PMID:15881942

No considerable influence of the treatment methods on delayed results and life span has been found (the difference is statistically insignificant). However good correlation has been found with the degree of tumor dissemination. The 5-year survival period in Stage 2 is 72-80%, in Stages 3, 4 17-25%. The effect of the fractionated dose technique has been studied in 113 patients, Stages 3 and 4, who were given radiotherapy and chemoradiotherapy. The correlation of the 5-year survival with the tumor stage, has also been established: in Stage 3, 14-20%, in Stage 4 6-10%. In the analysis of life span of the dead patients similar dependence on the treatment methods and dose fractionated technique has been obtained

    Vitamin C deficiency in developed countries is typically observed in patients with unique clinical conditions such as cystic fibrosis or anorexia nervosa, or in patients on long-term tube feeds. We report here a clinical observation in six pediatric and adolescent patients (median age 17.5 yr, range 9.8-23.5 yr) with chronic GVHD with mucous membrane involvement found to be vitamin C deficient. These patients' baseline serum vitamin C levels ranged from <0.12 to 0.94 mg/dL (normal value 0.20-1.90 mg/dL), with a mean level 0.56 ± 0.36 mg/dL and a median level 0.6 mg/dL. Among these patients, signs and symptoms of mucositis failed to respond to standard chronic GVHD therapy. After receiving treatment with 2000 mg of ascorbic acid by mouth, daily patients displayed increased serum vitamin C levels. Clinically, this correlated with a remarkable improvement in patients' mucositis and ability to eat. PMID:24816030

Finally we describe proteins that have been differentially expressed (versus controls) by individual cells which constitute atheroma plaques (endothelial cells, vascular smooth muscle cells, macrophages and foam cells) as well as by circulating cells (monocytes, platelets) or novel biomarkers present in plasma.

    In summarising the outcome of the present study it can be said spraying the agent on the oral mucous membrane once a day had an effect on the incidence of mucous membrane ulceration in the case of both placebo and dexpanthenol treatment. However, there was no significant difference between placebo and dexpanthenol treatment, the only finding being a slight prolongation of latency time through aloe vera. These experimental findings give good reason to critically reconsider the clinical use of dexpanthenol as a supportive treatment for the prevention of radiogenic mucositis enoralis following irradiation of tumours in the head and neck region. However thorough oral lavage is an effective means of moderating the irradiation response of the oral mucous membrane. [German] Zusammenfassend ist festzustellen, dass in den vorliegenden Versuchen mit einmal taeglichem Aufspruehen des Praeparates auf die Mundschleimhaut sowohl die Placebo - wie auch die Dexpanthenol-Behandlung die Inzidenz von Schleimhautulzerationen modifiziert hat; zwischen Placebo- und Dexpanthenol-Behandlung ergab sich jedoch kein signifikanter Unterschied. Lediglich eine geringe Verlaengerung der Latenzzeit durch Aloe vera war zu beobachten. Auf der Basis dieser experimentellen Ergebnisse muss der klinische Einsatz von Dexpanthenol im Rahmen der Supportivtherapie zur Prophylaxe der radiogenen Mucositis enoralis bei der Bestrahlung von Kopf-Hals-Tumoren kritisch ueberdacht werden. Regelmaessige, intensive Mundspuelungen sind jedoch ein probates Mittel zur Verminderung der Strahlenreaktion der Mundschleimhaut. (orig.)

    Full Text Available Background: In multilevel spinal cord compression caused by cervical spondylosis, surgeonsface the choice of performing a posterior route as a laminectomy orlaminoplasty, or an anterior route as multiple adjacent interbody decompressionsor corpectomies. The anterior cervical operation is not considered bysome clinicians because of concerns about complications and the complexityof multilevel anterior cervical surgery.Methods: In this retrospective study, 14 patients with multilevel cervical spondylosiswho were operated on via an anterior route were enrolled to evaluate thecomplexity, safety, and clinical results. The collected parameters were operationtime, blood loss, hospital days, and early and late complications forevaluating the operative complexity, radiographic follow-up for evaluatingfusion, graft problems, implants problems, and the recovery rate using theJapanese Orthopaedic Association score (JOA score for evaluating the operativeresults.Results: The mean operation time was 363.4 min, and blood loss was 431.4 ml. Anearly complication was noted in 1 patient with combined deep vein thrombosisand a pulmonary embolism. Late complications were screw breakage in1 patient and screw loosening in 5 patients. The mean duration of follow-upwas 21.9 months. The mean recovery rate of the JOA score was 38.8% postoperativelyand 51.9% at the final follow-up. The fusion rate was 100% inthis series.Conclusions: Anterior cervical decompression and fusion for multilevel stenosis requires alonger operation time than posterior procedures; however, the clinical resultsare satisfactory.

  18. Analysis of digitized cervical images to detect cervical neoplasia

    2004-05-01

    Cervical cancer is the second most common malignancy in women worldwide. If diagnosed in the premalignant stage, cure is invariably assured. Although the Papanicolaou (Pap) smear has significantly reduced the incidence of cervical cancer where implemented, the test is only moderately sensitive, highly subjective and skilled-labor intensive. Newer optical screening tests (cervicography, direct visual inspection and speculoscopy), including fluorescent and reflective spectroscopy, are fraught with certain weaknesses. Yet, the integration of optical probes for the detection and discrimination of cervical neoplasia with automated image analysis methods may provide an effective screening tool for early detection of cervical cancer, particularly in resource poor nations. Investigative studies are needed to validate the potential for automated classification and recognition algorithms. By applying image analysis techniques for registration, segmentation, pattern recognition, and classification, cervical neoplasia may be reliably discriminated from normal epithelium. The National Cancer Institute (NCI), in cooperation with the National Library of Medicine (NLM), has embarked on a program to begin this and other similar investigative studies.

    The availability of the human genome sequence has enabled the exploration and exploitation of the human genome and proteome to begin. Research has now focussed on the annotation of the genome and in particular of the proteome. With expert annotation extracted from the literature by biologists as the foundation, it has been possible to expand into the areas of data mining and automatic annotation. With further development and integration of pattern recognition methods and the application of alignments clustering, proteome analysis can now be provided in a meaningful way. These various approaches have been integrated to attach, extract and combine as much relevant information as possible to the proteome. This resource should be valuable to users from both research and industry. PMID:11301130

  11. Involved mechanisms in the radioprotector effect of the insulinic-1 type growth factor (IGF-1) in the mucous of the small intestine

    International Nuclear Information System (INIS)

    The use of radiant therapies in malignant tissues presents the inconvenience of affecting also to the healthy tissues, mainly when these present a high rate of proliferation like in the case of the mucous of the small intestine. The growth factor of insulinic-1 type (IGF-1) it has been pointed out as a possible protector of normal tissues under irradiation conditions. The objective of this work was to evaluate the effect of the IGF-1 like radioprotector of the mucous of the small intestine in mice irradiated with 10 Gy to whole body, determining the histological characteristics of the tissue, the presence of apoptotic cells, the expression of antigen of cellular proliferation (PCNA) and of anti-oxidant enzymes. Four groups of mice were used: control, treated with IGF-1, irradiated and irradiated and treated with IGF-1. The two treated groups were injected subcutaneously with two dose by day of 2.5 μg of IGF-I /0.1ml during four days (days 1 at 4). The two irradiated groups 10 Gy received to whole body the day 2. The day 5 all the animals were sacrificed and cuts of the mucous of the small intestine were obtained. The histological cuts were evaluated by tint with hematoxyline-eosin; the presence of apoptotic cells its were determined by the Tunnel method (Apoptag kit); the expression of PCNA, superoxide dependent dismutase of copper and zinc (CuZnSOD), superoxide dependent dismutase of manganese (MnSOD), catalase (CAT) and glutathion peroxidase (GPX), by immunohistochemistry. The results demonstrated that the treatment with IGF-1 preserves the partially histology of the mucous of the intestine, the expression of PCNA and the presence of apoptotic cells in the crypts in front of the irradiation. The CuZnSOD it was expressed mainly in the hairiness and, in smaller measure, in the crypts increase in the group IR+IGF-1. The IGF-1 produced the expression of MnSOD in the crypts and in the intestinal hairiness. The expression of CAT in the hairiness increase significantly

    Succination is a chemical modification of cysteine in protein by the Krebs cycle intermediate, fumarate, yielding S-(2-succino)cysteine (2SC). Intracellular fumarate concentration and succination of proteins are increased by hyperpolarization of the inner mitochondrial membrane, in concert with mitochondrial, endoplasmic reticulum (ER) and oxidative stress in adipocytes grown in high glucose medium and in adipose tissue in obesity and diabetes. Increased succination of proteins is also detected in the kidney of a fumarase conditional knock-out mouse which develops renal tumors. Keap1, the gatekeeper of the antioxidant response, was identified as a major succinated protein in renal cancer cells, suggesting that succination may play a role in activation of the antioxidant response. A wide range of proteins is subject to succination, including enzymes, adipokines, cytoskeletal proteins and ER chaperones with functional cysteine residues. There is also significant overlap between succinated and glutathionylated proteins, and with proteins containing cysteine residues that are readily oxidized to the sulfenic (cysteic) acid. Succination of adipocyte proteins is inhibited by uncouplers, which discharge the mitochondrial membrane potential (Δψm) and by ER stress inhibitors. 2SC serves as a biomarker of mitochondrial stress or dysfunction in chronic diseases, such as obesity, diabetes and cancer, and recent studies suggest that succination is a mechanistic link between mitochondrial dysfunction, oxidative and ER stress, and cellular progression toward apoptosis. In this article, we review the history of the succinated proteome and the challenges associated with measuring this non-enzymatic post-translational modification of proteins by proteomics approaches.

  13. Structural proteomics by NMR spectroscopy.

    Shin, Joon; Lee, Woonghee; Lee, Weontae

    2008-08-01

    Structural proteomics is one of the powerful research areas in the postgenomic era, elucidating structure-function relationships of uncharacterized gene products based on the 3D protein structure. It proposes biochemical and cellular functions of unannotated proteins and thereby identifies potential drug design and protein engineering targets. Recently, a number of pioneering groups in structural proteomics research have achieved proof of structural proteomic theory by predicting the 3D structures of hypothetical proteins that successfully identified the biological functions of those proteins. The pioneering groups made use of a number of techniques, including NMR spectroscopy, which has been applied successfully to structural proteomics studies over the past 10 years. In addition, advances in hardware design, data acquisition methods, sample preparation and automation of data analysis have been developed and successfully applied to high-throughput structure determination techniques. These efforts ensure that NMR spectroscopy will become an important methodology for performing structural proteomics research on a genomic scale. NMR-based structural proteomics together with x-ray crystallography will provide a comprehensive structural database to predict the basic biological functions of hypothetical proteins identified by the genome projects.

    Today we can state that in spite of a considerable number of cervical osteochondrosis studies, there is a lack of research devoted to analysis of its course. There is no correlation between initial expert evaluations of cervical osteo-chondrosis cases and further course of pathological process. Goal of the research is to develop system of course prognosis of cervical osteochondrosis taking into account environmental infuence, heredity, living conditions, psychological profle of patient’s personality. Materials and methods. Dynamics of degenerative-dystrophic changes progressing of cervical vertebrae in 236 patients was analyzed. Results. Received data demonstrated that probability of stage I changing to stage II, III and IV depended on patients’ sex, age and type of labour activity, frequent supercooling and stress. Probability of fast progression of cervical osteochondrosis (5-year cycle of stage I changing to stage III and IV was to a great extent associated with heredity, urban living, presence of endocrine system diseases, syndrome of nonspecifc dysplasia of connective tissue and low indices of quality of life. Conclusion. Proposed system allows making prognosis of morphologic changes in spinal cord, and is based on radiation methods of verifcation without taking into consideration dynamics of neurological symptomatology.

    Background Lower cervical dislocation with locked facets is common in cervical injury. The locked facets include unilateral and bilateral types. Different successful closed reduction rates has been achieved between unilateral and bilateral types by using rapid skull traction, which was commonly used to reduce the cervical dislocation. It is important to investigate a suitable management specific to patients with different types of cervical locked facets.Methods A total of 38 patients with cervical dislocation with locked facet due to cervical injury treated by rapid skull traction and operation from 1988 to 2005 were reviewed. Rapid skull traction was used in all the patients. Successful closed reduction rate was 88.0% in patients with bilateral cervical locked facets and that was 15.4% in those with unilateral cervical locked facets. These data were then statistically compared by Chi-square test. Patients who were reduced successfully underwent anterior cervical discectomy and fusion at the injured level, and those who failed in closed reduction received posterior open reduction and fixation.Results In this series, there was statistically significant difference (P<0.05) in the rate of successful closed skull traction reduction between unilateral and bilateral locked facets dislocation. Unilateral cervical locked facets dislocation was not easily reduced by skull traction which was suitable for reduction of bilateral cervical locked facets dislocation. However,unilateral cervical locked facets dislocation can be reduced by posterior open reduction.Conclusions Unilateral cervical locked facets dislocation should be treated immediately with posterior open reduction and instrumentation. Bilateral cervical locked facets dislocation can be reduced by rapid skull traction firstly and anterior cervical discectomy and interbody fusion later.

    2013-05-01

    Programmed cell death is a ubiquitous process of utmost importance for the development and maintenance of multicellular organisms. More than 10 different types of programmed cell death forms have been discovered. Several proteomics analyses have been performed to gain insight in proteins involved in the different forms of programmed cell death. To consolidate these studies, we have developed the cell death proteomics (CDP) database, which comprehends data from apoptosis, autophagy, cytotoxic granule-mediated cell death, excitotoxicity, mitotic catastrophe, paraptosis, pyroptosis, and Wallerian degeneration. The CDP database is available as a web-based database to compare protein identifications and quantitative information across different experimental setups. The proteomics data of 73 publications were integrated and unified with protein annotations from UniProt-KB and gene ontology (GO). Currently, more than 6,500 records of more than 3,700 proteins are included in the CDP. Comparing apoptosis and autophagy using overrepresentation analysis of GO terms, the majority of enriched processes were found in both, but also some clear differences were perceived. Furthermore, the analysis revealed differences and similarities of the proteome between autophagosomal and overall autophagy. The CDP database represents a useful tool to consolidate data from proteome analyses of programmed cell death and is available at http://celldeathproteomics.uio.no. PMID:23537399

    Human papillomavirus (HPV) testing is more reliable and sensitive but less specific than Papanicolaou (Pap) testing/cervical cytology for the detection of cervical precancer and cancer. HPV-negative women are at lower risk of cervical cancer than Pap-negative women. In high-resource settings, HPV testing can be used to make cervical cancer prevention programs more efficient by focusing clinical attention on women who have HPV. In lower-resource settings, where Pap testing has not been sustained or widespread, new, lower-cost HPV tests may make cervical cancer screening feasible. PMID:23732037

    Cervical spine injuries of children, though rare, have a high morbidity and mortality. The pediatric cervical spine is anatomically and biomechanically different from that of adults. Hence, the type, level and outcome of cervical spine injuries in children are different from those seen in adults. Normal developmental variants seen in children can make evaluation of the pediatric cervical spine challenging. This article reviews the epidemiology of pediatric cervical spine trauma, normal variants seen in children and specific injuries that are more common in the pediatric population. We also propose an evidence-based imaging protocol to avoid unnecessary imaging studies and minimize radiation exposure in children. (orig.)

    2016-03-01

    Evolutionary ecologists are traditionally gene-focused, as genes propagate phenotypic traits across generations and mutations and recombination in the DNA generate genetic diversity required for evolutionary processes. As a consequence, the inheritance of changed DNA provides a molecular explanation for the functional changes associated with natural selection. A direct focus on proteins on the other hand, the actual molecular agents responsible for the expression of a phenotypic trait, receives far less interest from ecologists and evolutionary biologists. This is partially due to the central dogma of molecular biology that appears to define proteins as the 'dead-end of molecular information flow' as well as technical limitations in identifying and studying proteins and their diversity in the field and in many of the more exotic genera often favored in ecological studies. Here we provide an overview of a newly forming field of research that we refer to as 'Evolutionary Proteomics'. We point out that the origins of cellular function are related to the properties of polypeptide and RNA and their interactions with the environment, rather than DNA descent, and that the critical role of horizontal gene transfer in evolution is more about coopting new proteins to impact cellular processes than it is about modifying gene function. Furthermore, post-transcriptional and post-translational processes generate a remarkable diversity of mature proteins from a single gene, and the properties of these mature proteins can also influence inheritance through genetic and perhaps epigenetic mechanisms. The influence of post-transcriptional diversification on evolutionary processes could provide a novel mechanistic underpinning for elements of rapid, directed evolutionary changes and adaptations as observed for a variety of evolutionary processes. Modern state-of the art technologies based on mass spectrometry are now available to identify and quantify peptides, proteins, protein

    The flower is the most important biological structure for ensuring angiosperms reproductive success. Not only does the flower contain critical reproductive organs, but the wide variation in morphology, color, and scent has evolved to entice specialized pollinators, and arguably mankind in many cases, to ensure the successful propagation of its species. Recent proteomic approaches have identified protein candidates related to these flower traits, which has shed light on a number of previously unknown mechanisms underlying these traits. This review article provides a comprehensive overview of the latest advances in proteomic research in floral biology according to the order of flower structure, from corolla to male and female reproductive organs. It summarizes mainstream proteomic methods for plant research and recent improvements on two dimensional gel electrophoresis and gel-free workflows for both peptide level and protein level analysis. The recent advances in sequencing technologies provide a new paradigm for the ever-increasing genome and transcriptome information on many organisms. It is now possible to integrate genomic and transcriptomic data with proteomic results for large-scale protein characterization, so that a global understanding of the complex molecular networks in flower biology can be readily achieved.

    Full Text Available In recent years, platelet proteomics has been applied successfully to the study of cardiovascular diseases (CVDs. It is very well known that platelets play a pivotal role in the pathophysiological mechanisms underlying many CVDs, especially acute coronary syndromes (ACSs, since they are implied in thrombus formation after atheroma plaque rupture. This is the reason why molecules involved in platelet activation and aggregation are primary targets for treatment of ACSs. Many efforts are aimed at finding drugs that inhibit platelet activation; however it is difficult to separate the therapeutic benefits from harmful effects because pathological and physiological functions of platelets are due to the same mechanisms. Given that platelets lack a nucleus, proteomics is regarded as an ideal method to approach their biochemistry. Current platelet proteomic studies are focusing on the identification of platelet molecular and functional changes in normal and pathological states, enriching the comprehension of platelet biological function, and screening for new biomarkers and antiplatelet agents. In the present article, we introduce the reader to platelet biology and function, and revise recent advances in platelet proteomics applied to the study of CVDs, including a special emphasis on sample preparation requirements for proteome analysis of platelet clinical samples.

    While genomic approaches have been applied for the detection and identification of individual bacteria within microbial communities, analogous proteomics approaches have been effectively precluded due to their inherent complexity. An in silico assessment of peptides that could potentially be present in the proteomes of artificial simple and complex communities was performed to evaluate the effect of proteome complexity on species detection. A mass spectrometry-based proteomics approach was employed to experimentally detect and validate the predicted tryptic peptides initially identified as distinctive within the simple community. An assessment of peptide distinctiveness and the potential for mapping to a particular bacterium within a community was made throughout each step of the study. A second in silico assessment of peptide distinctiveness for a complex community of 25 microorganisms was conducted to investigate the levels of instrumental performance that would be required to experimentally detect these peptides, as well as how performance varied with complexity (e.g., the number of different microorganisms). The experimental data for a simple community showed that it is feasible to predict, observe, and to quantify distinctive peptides from one organism in the presence of at least a 100-fold greater abundance of another, thus yielding putative markers for identifying a bacterium of interest. This work represents a first step towards quantitative proteomic characterization of complex microbial communities and the possible development of community wide markers of perturbations to such communities.

    Stinging cells or nematocytes of jellyfish and other cnidarians represent one of the most poisonous and sophisticated cellular inventions in animal evolution. This ancient cell type is unique in containing a giant secretory vesicle derived from the Golgi apparatus. The organelle structure within the vesicle comprises an elastically stretched capsule (nematocyst) to which a long tubule is attached. During exocytosis, the barbed part of the tubule is accelerated with >5 million g in <700 ns, enabling a harpoon-like discharge (Nüchter, T., Benoit, M., Engel, U., Ozbek, S., and Holstein, T. W. (2006) Curr. Biol. 16, R316–R318). Hitherto, the molecular components responsible for the organelle's biomechanical properties were largely unknown. Here, we describe the proteome of nematocysts from the freshwater polyp Hydra magnipapillata. Our analysis revealed an unexpectedly complex secretome of 410 proteins with venomous and lytic but also adhesive or fibrous properties. In particular, the insoluble fraction of the nematocyst represents a functional extracellular matrix structure of collagenous and elastic nature. This finding suggests an evolutionary scenario in which exocytic vesicles harboring a venomous secretome assembled a sophisticated predatory structure from extracellular matrix motif proteins.

    Herpesviruses are highly prevalent viruses associated with numerous pathologies both in animal and human populations. Until now, most of the strategies used to prevent or to cure these infections have been unsuccessful because these viruses have developed numerous immune evasion mechanisms. Therefore, a better understanding of their complex lifecycle is needed. In particular, while the genome of numerous herpesviruses has been sequenced, the exact composition of virions remains unknown for most of them. Mass spectrometry has recently emerged as a central method and has permitted fundamental discoveries in virology. Here, we review mass spectrometry-based approaches that have recently allowed a better understanding of the composition of the herpesvirus virion. In particular, we describe strategies commonly used for proper sample preparation and fractionation to allow protein localization inside the particle but also to avoid contamination by nonstructural proteins. A collection of other important data regarding post-translational modifications or the relative abundance of structural proteins is also described. This review also discusses the poorly studied importance of host proteins in herpesvirus structural proteins and the necessity to develop a quantitative workflow to better understand the dynamics of the structural proteome. In the future, we hope that this collaborative effort will assist in the development of new strategies to fight these infections. PMID:26907323

  15. Myelopathy hand in cervical radiculopathy

    International Nuclear Information System (INIS)

    The so-called 'myelopathy hand', or characteristic finger paralysis, often recognized in cervical compression myelopathy, has been considered a unique manifestation of cervical myelopathy. We used our original grip and release test, a 15-second test in which finger motion is captured with a digital camera, to investigate whether cervical radiculopathy has the same characteristics as myelopathy hand. Thirty patients with pure radiculopathy, id est (i.e.), who had radiating arm pain and evidence of corresponding nerve root impingement on X-ray images or MRI scans, but did not have spinal cord compression, served as the subjects. In contrast to other radiculopathies, C7 radiculopathy was manifested by a significant reduction in the number of finger motion cycles on the affected side in comparison with the unaffected side, the same as in myelopathy hand. Uncoordinated finger motion was significantly more frequent on the affected side in C6 radiculopathy than on the unaffected side. These findings contradict the conventional notion that myelopathy hand is a unique manifestation of cervical myelopathy, but some radiculopathies manifested the same kinds of finger paralysis observed in myelopathy hand.

    Cervical radiculopathy describes pain in one or both of the upper extremities, often in the setting of neck pain, secondary to compression or irritation of nerve roots in the cervical spine. It can be accompanied by motor, sensory, or reflex deficits and is most prevalent in persons 50 to 54 years of age. Cervical radiculopathy most often stems from degenerative disease in the cervical spine. The most common examination findings are painful neck movements and muscle spasm. Diminished deep tendon reflexes, particularly of the triceps, are the most common neurologic finding. The Spurling test, shoulder abduction test, and upper limb tension test can be used to confirm the diagnosis. Imaging is not required unless there is a history of trauma, persistent symptoms, or red flags for malignancy, myelopathy, or abscess. Electrodiagnostic testing is not needed if the diagnosis is clear, but has clinical utility when peripheral neuropathy of the upper extremity is a likely alternate diagnosis. Patients should be reassured that most cases will resolve regardless of the type of treatment. Nonoperative treatment includes physical therapy involving strengthening, stretching, and potentially traction, as well as nonsteroidal anti-inflammatory drugs, muscle relaxants, and massage. Epidural steroid injections may be helpful but have higher risks of serious complications. In patients with red flag symptoms or persistent symptoms after four to six weeks of treatment, magnetic resonance imaging can identify pathology amenable to epidural steroid injections or surgery.

    Most upper esophageal malignancies are squamous cell carcinomas, rarely adenocarcinomas arising from Barrett's esophagus and very rarely adenocarcinomas from heterotopic gastric mucosa without evidence of Barrett's especially in the cervical part of the esophagus. We report a case of adenocarcinoma of the polypoid type in the upper esophagus (cervical esophagus) arising from ectopic gastric mucosa, in a 60 year-old man who presented with progressive dysphagia. Accurate diagnosis by esophagogram revealed a large mass in the cervical esophagus; CAT scan showed intraluminal mass at the level of thoracic inlet, esophagogastroscopy showed a fleshy polyp (3.2cm x 3.0cm) at 20 cm from the incisors with a biopsy confirming moderately differentiated adenocarcinoma with no evidence of Barrett's esophagus. Through a left cervical approach and resection of medial third of clavicle, the tumor was removed by partial esophagectomy followed by lymph node dissection, and proved to be T1NOMO, stage I (AJCC staging 6th ed.). Post operatively, the patient received chemoradiation with no evidence of recurrence or metastasis in six years of follow up. It seems this tumor has a much better prognosis than adenocarcinomas arising from Barrett's. To our knowledge only 19 cases have been reported in literature so far. PMID:16110768

    The aim of this study was to describe the method and the value of cervical discography as correlated with the MR findings. Twenty-one discs in 11 consecutive patients who underwent cervical discography were analyzed. MR and CT discography (CTD) were performed in all patients. Discography was performed after swallowing barium for visualizing the pharynx and the esophagus to prevent penetration. We also analyzed the preceding causes of the subjects' cervical pain. The results of the pain provocation test were classified into concordant pain, discordant pain and a negative test. MRI was analyzed according to the T2-signal intensity (SI) of the disc, disc height, annular bulging and disc herniation. The CTD was analyzed for degeneration or radial tear of the disc, epidural leakage of the contrast agent and pooling of the contrast agent at the periphery of the disc. The pain provocation tests were correlated with the MR and CTD findings. We used the chi-square test to analyze the results. Concordant pain was observed in 14 cases, discordant pain in 3 cases and there were negative tests in 4 cases. There were no complications related to the procedure. Four patients had undergone anterior cervical fusion and four patients that developed after traffic injuries. The decreased T2-SI and annular bulging on MRI, disc degeneration and peripheral pooling of the contrast agent on CT were significantly correlated with pain provocation. When the diagnosis of disc disease is difficult with performing MRI, cervical discography with using swallowed barium solution to reduce the penetration of the esophagus or hypopharynx may play be helpful. The decreased T2-SI and annular bulging on MRI correlated significantly with a positive result on the pain provocation test.

    Mariana P Torrente

    Full Text Available Chromatin proteins provide a scaffold for DNA packaging and a basis for epigenetic regulation and genomic maintenance. Despite understanding its functional roles, mapping the chromatin proteome (i.e. the "Chromatome" is still a continuing process. Here, we assess the biological specificity and proteomic extent of three distinct chromatin preparations by identifying proteins in selected chromatin-enriched fractions using mass spectrometry-based proteomics. These experiments allowed us to produce a chromatin catalog, including several proteins ranging from highly abundant histone proteins to less abundant members of different chromatin machinery complexes. Using a Normalized Spectral Abundance Factor approach, we quantified relative abundances of the proteins across the chromatin enriched fractions giving a glimpse into their chromosomal abundance. The large-scale data sets also allowed for the discovery of a variety of novel post-translational modifications on the identified chromatin proteins. With these comparisons, we find one of the probed methods to be qualitatively superior in specificity for chromatin proteins, but inferior in proteomic extent, evidencing a compromise that must be made between biological specificity and broadness of characterization. Additionally, we attempt to identify proteins in eu- and heterochromatin, verifying the enrichments by characterizing the post-translational modifications detected on histone proteins from these chromatin regions. In summary, our results provide insights into the value of different methods to extract chromatin-associated proteins and provide starting points to study the factors that may be involved in directing gene expression and other chromatin-related processes.

    Full Text Available Pregnancy-related complications such as pre-eclampsia and preterm birth now represent a notable burden of adverse health. Pre-eclampsia is a hypertensive disorder unique to pregnancy. It is an important cause of maternal death worldwide and a leading cause of fetal growth restriction and iatrogenic prematurity. Fifteen million infants are born preterm each year globally, but more than one million of those do not survive their first month of life. Currently there are no predictive tests available for diagnosis of these pregnancy-related complications and the biological mechanisms of the diseases have not been fully elucidated. Mass spectrometry-based proteomics have all the necessary attributes to provide the needed breakthrough in understanding the pathophysiology of complex human diseases thorough the discovery of biomarkers. The mass spectrometry methodologies employed in the studies for pregnancy-related complications are evaluated in this article. Top-down proteomic and peptidomic profiling by laser mass spectrometry, liquid chromatography or capillary electrophoresis coupled to mass spectrometry, and bottom-up quantitative proteomics and targeted proteomics by liquid chromatography mass spectrometry have been applied to elucidate protein biomarkers and biological mechanism of pregnancy-related complications. The proteomes of serum, urine, amniotic fluid, cervical-vaginal fluid, placental tissue, and cytotrophoblastic cells have all been investigated. Numerous biomarkers or biomarker candidates that could distinguish complicated pregnancies from healthy controls have been proposed. Nevertheless, questions as to the clinically utility and the capacity to elucidate the pathogenesis of the pre-eclampsia and preterm birth remain to be answered.

    The second cervical spinal nerves are unduly vulnerable to forcible approximation of the arches of the atlas and axis and to excessive rotation of the atlas on the axis. Sequelae of such injury include sensory aberrations ranging from loss of feeling to severe neuralgia and disorders of balance. Diagnosis of second cervical neuropathy may be difficult when there are multiple injuries to the cervical spine, but most cases clear up spontaneously within one to three years.

    Background It was reported that telomerase expression is closely associated with cellular immortality and cancer. This study was designed to investigate the relationship between telomerase expression and the carcinogenesis of cervical cancer, the possible use of telomerase as a marker of cervical intraepithelial neoplasia (CIN) progression or regression, and the natural history of CIN. Methods Telomeric repeat amplification protocol (TRAP) assay was used to measure telomerase activity in cervical scrapings and biopsy samples obtained from 105 cases affected with various cervical conditions, including chronic cervicitis (n=20), CIN (n=64, 16 cases of CIN Ⅰ , 20 cases of CIN Ⅱ, and 28 cases of CIN Ⅲ ), and invasive squamous cell carcinoma (n =21 ).Results In exfoliated cell samples, telomerase activity was detected in 5 of 20 (25. 0% ) cases of cervicitis, 10 of 16 (62.5%) cases of CIN Ⅰ , 11 of 20 (55.0%) cases of CIN Ⅱ, 23 of 28 (82.1%) cases of CIN Ⅲ, and 13 of 21 (61.9%) cases of carcinoma. In cervical biopsy samples, telomerase activity was detected in 6 of 20 (30. 0%) cases of cervicitis, 8 of 16 (50. 0%) cases of CIN Ⅰ , 9 of 20 (45.0%) cases of (CIN Ⅱ, 27 of 28 (96. 4%) cases of CIN Ⅲ, and 20 of 21 (95. 2%) cases of carcinoma. Telomerase activation was significantly higher in CIN samples than in cervicitis samples. Telomerase activity was detected at similar frequency in samples from cervical scrapings and cervical biopsies.Conclusion These results seem to suggest that telomerase expression may be associated with carcinogenesis of the cervix. TRAP assay of cervical scraping samples could be used to monitor and predict the development of CIN in clinical practice.

    Instrumentation of the cervical spine enhances stability and improves arthrodesis rates in children undergoing surgery for deformity or instability. Various morphologic and clinical studies have been conducted in children, confirming the feasibility of anterior or posterior instrumentation of the cervical spine with modern implants. Knowledge of the relevant spine anatomy and preoperative imaging studies can aid the clinician in understanding the pitfalls of instrumentation for each patient. Preoperative planning, intraoperative positioning, and adherence to strict surgical techniques are required given the small size of children. Instrumentation options include anterior plating, occipital plating, and a variety of posterior screw techniques. Complications related to screw malposition include injury to the vertebral artery, neurologic injury, and instrumentation failure. PMID:27097300

    Despite the development of screening and of a vaccine, cervix cancer is a major cause of cancer death in young women worldwide. A third of women treated for the disease will recur, almost inevitably leading to death. Functional imaging has the potential to stratify patients at higher risk of poor response or relapse by improved delineation of disease extent and tumor characteristics. A number of molecular imaging biomarkers have been shown to predict outcome at baseline and/or early during therapy in cervical cancer. In future this could help tailor the treatment plan which could include selection of patients for close follow up, adjuvant therapy or trial entry for novel agents or adaptive clinical trials. The use of molecular imaging techniques, FDG PET/CT and functional MRI, in staging and response assessment of cervical cancer is reviewed. PMID:26859085

    Objective: To evaluate factors for prognosis of cervical carcinoma. Methods: Expressions of mn23- HI, erbB3 and erbB4 were examined by immunohistochemical staining. The apoptosis was detected in situ by the TdT mediated duip-biotin nick end-labeling (TUNEL) technique. Mitotic cell were counted by HE dyeing. Results: FIGO stage and lymph node metastasis were the most important factors for evaluating prognosis in adenocarcinoma or squamous cell carcinoma. AI/MI was positively correlated with 5-year survival of cervical carcinoma. Positive expression of nm23-H1 combed with negative expression of erbB4 [nm23-H1(+)/erbB4(-)] predicted good prognosis for adeno-carcinoma. In multivariable Cox regression analysis, only FIGO stage and AI/MI were into equation. Conclusion: FIGO stage and AI/MI were independent evaluating parameter for adenocarcinoma or squamous cell carcinoma.

    Full Text Available In case of invasive cervical carcinoma several molecular events were reported and these molecular events resulting in multiple genetic abnormalities. In order to control these tumors multiple molecular therapeutic targets are needed with different molecular mechanisms. Unfortunately, these molecular targets were in early stages of development. Because of less degree of success of conventional therapeutics for late stages of cervical cancer and lowering of prognosis of patients there is an increase in interest for the development of potential therapeutic targets for cervical cancer. This review article emphasizes the current molecular targeted agents; with special attention to estrogen receptors for human papilloma virus infected cervical cancer.

  8. The effect of serum on the secretion of radiolabeled mucous macromolecules into the lumen of the cat trachea

    International Nuclear Information System (INIS)

    We studied the effect of placing serum within a segment of trachea on secretion into its lumen in the cat. A segment of cervical trachea was isolated from the rest of the airway in situ. Secretions were radiolabeled biosynthetically by the administration of two radiolabeled precursors: [35S]sodium sulphate and [3H]glucose. Autologous serum placed in the segment at a dilution of 1 in 8 increased the output of radiolabeled macromolecules: [35S] by 80% and [3H] by 159% (p less than 0.001). At a dilution of 1 in 24, serum still increased the output of both isotopes. At dilutions of 1 in 48 and 1 in 80 the increases were significant for [35S] but not for [3H]. Heating the serum to 90 degrees C diminished its effects. Fractionating the serum by dialysis and gel filtration showed that the components of molecular weight less than about 13,000 daltons had no effect on secretion, whereas three higher molecular weight fractions all increased secretion. Two alien proteins (horseradish peroxidase and bovine serum albumin) stimulated secretion but a large molecular weight carbohydrate (carboxymethyl cellulose) did not. Atropine and propranolol, at doses that greatly reduced the effect of parasympathetic and sympathetic nerve activity, did not diminish the effects of serum, which therefore appeared to be independent of nerve activity. Gel filtration of the secretions elicited by serum showed that the predominant component was excluded even by Sepharose CL-2B and thus had a high molecular weight. We conclude that there are several components of serum that promote the secretion of mucus glycoproteins into the cat trachea. The relevance of these findings to diseases of human airways is considered

    The authors report a retrospective assessment of acute, cutaneous and mucous toxicity resulting from an association of cetuximab and conventional conformational radiotherapy, and from an intensity-modulated conformational radiotherapy (IMRT). Seven patients presenting nasopharyngeal, oropharyngeal or hypopharyngeal tumours have been irradiated with intensity modulation, and seven without. It appears that the association of cetuximab and radiotherapy is not well tolerated and requires a close monitoring. Intensity-modulated radiotherapy allows a significant reduction of dose and of toxicity. However, mucous toxicity remains significant. Short communication

    Synovial fluid is present in all joint cavities, and protects the articular cartilage surfaces in large by lubricating the joint, thus reducing friction. Several studies have described changes in the protein composition of synovial fluid in patients with joint disease. However, the protein concentration, content, and synovial fluid volume change dramatically during active joint diseases and inflammation, and the proteome composition of healthy synovial fluid is incompletely characterized. We performed a normative proteomics analysis of porcine synovial fluid, and report data from optimizing proteomic methods to investigate the proteome of healthy porcine synovial fluid (Bennike et al., 2014 [1]). We included an evaluation of different proteolytic sample preparation techniques, and an analysis of posttranslational modifications with a focus on glycosylation. We used pig (Sus Scrofa) as a model organism, as the porcine immune system is highly similar to human and the pig genome is sequenced. Furthermore, porcine model systems are commonly used large animal models to study several human diseases. In addition, we analyzed the proteome of human plasma, and compared the proteomes to the obtained porcine synovial fluid proteome. The proteome of the two body fluids were found highly similar, underlining the detected plasma derived nature of many synovial fluid components. The healthy porcine synovial fluid proteomics data, human rheumatoid arthritis synovial fluid proteomics data used in the method optimization, human plasma proteomics data, and search results, have been deposited to the ProteomeXchange Consortium via the PRIDE partner repository with the dataset identifier PXD000935.

    Mass spectrometry (MS)-based proteome analysis relies heavily on the presence of complete protein databases. Such a strategy is extremely powerful, albeit not adequate in the analysis of unpredicted postgenome events, such as posttranslational modifications, which exponentially increase the search space. Therefore, it is of interest to explore "database-free" approaches. Here, we sampled the ostrich and human proteomes with a method facilitating de novo sequencing, utilizing the protease Lys-N in combination with electron transfer dissociation. By implementing several validation steps, including the combined use of collision-induced dissociation/electron transfer dissociation data and a cross-validation with conventional database search strategies, we identified approximately 2,500 unique de novo peptide sequences from the ostrich sample with over 900 peptides generating full backbone sequence coverage. This dataset allowed the appropriate positioning of ostrich in the evolutionary tree. The described database-free sequencing approach is generically applicable and has great potential in important proteomics applications such as in the analysis of variable parts of endogenous antibodies or proteins modified by a plethora of complex posttranslational modifications.

    Full Text Available BACKGROUND AND PURPOSE: Tandem acute thrombotic emboli in the cervical and intracranial arteries are an unusual case of stroke presenting unique management challenges. In regional systems of acute stroke care anchored by Comprehensive Stroke Centers, combined fibrinolytic, endovascular, and open surgical intervention is a new therapeutic option. SUMMARY OF CASE: A 28 year old male underwent retinal surgery, including post-operative neck compression and the next day presented to a primary stroke center with aphasia and right hemiplegia. Intravenous tissue plasminogen activator therapy was initiated and the patient was transferred to a comprehensive stroke center (CSC for higher level of care (drip and ship. Imaging at the CSC demonstrated tandem thrombi: a near occlusive lesion at the origin of the left cervical internal carotid artery and a total occlusion of the M1 segment of the left middle cerebral artery. Endovascular thrombectomy with the Solitaire stent retriever resulted in intracranial recanalization (grip. Immediately after the endovascular procedure, open carotid thrombectomy was performed to achieve cervical carotid revascularization without systemic heparinization (slice. Both cervical carotid and intracranial thrombi were processed for proteomic analysis via mass spectrometry (dice. CONCLUSION: Combined fibrinolytic, endovascular, and open surgical intervention can yield revascularization and good clinical outcome in cases of tandem lesions.

    Significance: The current study provides the first proteomic profile of an oocyte of a cnidarian organism the starlet sea anemone N. vectensis and gives new insights on the ancient origin of an oocyte proteome template. The comparative analysis with a chordate oocyte suggests that the oocyte proteome predates the divergence of the cnidarian and bilaterian lineages. In addition, the data generated in the study will serve as a valuable resource for further developmental and evolutional studies.

  1. Intracavitary γ-therapy in combined treatment of cervical cancer with different dose fractionation

    International Nuclear Information System (INIS)

    A cooperative study of comparative assessment of the efficacy of 3 dose fractionation regimes in intracavitary γ-therapy used in combined radiation therapy of cervical cancer is presented (5 Gy, 10 fractions, 2-3 times a week; 7 Gy, 7 fractions, once in 5 days; 10 Gy, 4 fractions, once a week). Over the period of 1979-1983 1193 patients were treated by uniform methods of intracavitary and distant irradiation. The groups were identical with relation to the number of patients, stage of disease, histological characterization and growth type. By the end of therapy the cure rate among 1183 patients was 90-3%. In 2-3 months the cure rate in the same group was 97.5%. Delayed regression was most noticeable in stages I and III. The 5-year survival rates in 3 groups were: for stage I - 95.3±2.6%; for stage II - 83.1±2.5%; for stage III - 73.3±4.7%. In stage I and II tumors the 5-year survival rates in different regiments were similar whereas in stage III better results were obtained with a fractional dose of 5 Gy. The frequency and degree of severity of late radiation complications of the rectum, bladder,vaginal mucous membrane grew with an increase in a fractional dose

    Recent years have witnessed spectacular progress in the field of mass spectrometry (MS)-based quantitative proteomics, including advances in instrumentation, chromatography, sample preparation methods, and experimental design for multidimensional analyses. It is now possible not only to identify most of the protein components of a cell proteome in a single experiment, but also to describe additional proteome dimensions, such as protein turnover rates, posttranslational modifications, and subcellular localization. Furthermore, by comparing the proteome at different time points, it is possible to create a "time-lapse" view of proteome dynamics. By combining high-throughput quantitative proteomics with detailed subcellular fractionation protocols and data analysis techniques it is also now possible to characterize in detail the proteomes of specific subcellular organelles, providing important insights into cell regulatory mechanisms and physiological responses. In this chapter we present a reliable workflow and protocol for MS-based analysis and quantitation of the proteome of nucleoli isolated from human cells. The protocol presented is based on a SILAC analysis of human MCF10A-Src-ER cells with analysis performed on a Q-Exactive Plus Orbitrap MS instrument (Thermo Fisher Scientific). The subsequent chapter describes how to process the resulting raw MS files from this experiment using MaxQuant software and data analysis procedures to evaluate the nucleolar proteome using customized R scripts.

    The aim of work was to evaluate the frequency of occurrence of bacteria from genera of Micrococcus, Kocuria, Nesterenkonia, kytococcus and Dermatococcus on human skin and mucous membranes in healthy population. Among 150 investigated persons these bacteria were found in 122 (81.3%). The frequency of isolation was similar in both sex (82.4% in female and 79.7% in male). Most often the strains were isolated from oral cavity (48.7%), and from skin of palm and forearm (40.7% and 37.3%). Least frequency of occurrence was observed in vestibule of nose (26%). The predominant isolated strains were: M. luteus (26.2%), and N. halobia (21%) followed by K. varians (16.4%), M. lylae (12.2%), D. sedentarius (9.1%), K. kristinae (7.3%), K. nishinomiyaensis (7.3%), K. rosea (0.3%).

  12. Sport injuries of the cervical spine

    International Nuclear Information System (INIS)

    The article reports on injuries of the cervical spine occurring during sports activities. An attempt is made to reconstruct the movements which led to the cervical spine injuries in question. In two cases of accidents occuring during bathing, one football accident and a toboggan accident, the injuries concerned point to hyperextension of the cervical spine as cause of the injury. In another football accident and a riding accident, the changes observed allow us to conclude that the movement leading to the injury must have been a hyperflexion. One accident occurring while jumping on the trampolin resulted in an injury of the upper cervical spine pointing to the action of a compressive force on the cervical spine in addition to the force resulting in hyperflexion.

    2012-02-01

    The surgical treatment of cervical spondylosis and resulting cervical radiculopathy or myelopathy has evolved over the past century. Surgical options for dorsal decompression of the cervical spine includes the traditional laminectomy and laminoplasty, first described in Asia in the 1970\\'s. More recently the dorsal approch has been explored in terms of minimally invasive options including foraminotomies for nerve root descompression. Ventral decompression and fusion techniques are also described in the article, including traditional anterior cervical discectomy and fusion, strut grafting and cervical disc arthroplasty. Overall, the outcome from surgery is determined by choosing the correct surgery for the correct patient and pathology and this is what we hope to explain in this brief review.

    2008-01-01

    Cervical arthroplasty after anterior decompression with insertion of a prosthetic total disc replacement has been suggested as an alternate to anterior cervical fusion. It develops quickly during recent years. Currently there are several cervical arthroplasty devices. Each device varies in terms of materials, range of motion and constraint. Early studies suggest that in the short term, the complication rate and efficacy is no worse than fusion surgery. Long-term results have not yet been reported. This review examines the current prostheses as well as discussing issues regarding indications and technique. It is hoped that an improvement of cervical arthroplasty occurs in terms of materials and design as spinal surgeons enter a new dines of the management of cervical spine disease.

    A markedly increased risk of cervical cancer is known in women immunosuppressed due to AIDS or therapy following organ transplantation. The aim of this review is to determine the association between other conditions affecting the immune system and the risk of cervical cancer. Patients with end......-stage renal disease seem to be at an increased risk of cervical cancer. A higher risk of cervical precancerous lesions was found in patients with some autoimmune diseases; particularly if treated with immunosuppressants. Among behavioral factors weakening the immune system, smoking appeared to strongly...... increase the risk of cervical cancer, while poor diet only moderately increased the risk.

    2015-01-01

    BACKGROUND: The Faroe Islands have had nationally organised cervical cancer screening since 1995. Women aged 25-60 years are invited every third year. Participation is free of charge. Although several European overviews on cervical screening are available, none have included the Faroe Islands. Our...... aim was to provide the first description of cervical cancer screening, and to determine the screening history of women diagnosed with cervical cancer in the Faroe Islands.

    We describe three patients with misdiagnosed unstable fractures of the cervical spine, who were treated conservatively and developed kyphotic deformity, myelopathy, and radiculopathy. All three patients were then managed with closed reductions by crown halo traction, followed by instrumented fusions. Their neurologic function was regained without permanent disability in any patient. Unstable fractures of the cervical spine will progress to catastrophic neurologic injuries without surgical fixation. Posttraumatic kyphosis and the delayed reduction of partially healed fracture dislocations by preoperative traction are not well characterized in the subaxial cervical spine. The complete evaluation of any subaxial cervical spine fracture requires CT scanning to assess for bony fractures, and MRI to assess for ligamentous injury. This allows for assessment of the degree of instability and appropriate management. In patients with delayed posttraumatic cervical kyphosis, preoperative closed reduction provided adequate realignment, facilitating subsequent operative stabilization. PMID:26321304

    Dongli eHe

    2013-07-01

    Full Text Available Seed is a condensed form of plant. Under suitable environmental conditions, it can resume the metabolic activity from physiological quiescent status, and mobilize the reserves, biosynthesize new proteins, regenerate organelles and cell membrane, eventually protrude the radicle and enter into seedling establishment. So far, how these activities are regulated in a coordinated and sequential manner is largely unknown. With the availability of more and more genome sequence information and the development of mass spectrometry (MS technology, proteomics has been widely applied in analyzing the mechanisms of different biological processes, and proved to be very powerful. Regulation of rice seed germination is critical for rice cultivation. In recent years, a lot of proteomic studies have been conducted in exploring the gene expression regulation, reserves mobilization and metabolisms reactivation, which brings us new insights on the mechanisms of metabolism regulation during this process. Nevertheless, it also invokes a lot of questions. In this mini-review, we summarized the progress in the proteomic studies of rice seed germination. The current challenges and future perspectives were also discussed, which might be helpful for the following studies.

  19. Proteomic Investigations into Hemodialysis Therapy

    Directory of Open Access Journals (Sweden)

    Mario Bonomini

    2015-12-01

    Full Text Available The retention of a number of solutes that may cause adverse biochemical/biological effects, called uremic toxins, characterizes uremic syndrome. Uremia therapy is based on renal replacement therapy, hemodialysis being the most commonly used modality. The membrane contained in the hemodialyzer represents the ultimate determinant of the success and quality of hemodialysis therapy. Membrane’s performance can be evaluated in terms of removal efficiency for unwanted solutes and excess fluid, and minimization of negative interactions between the membrane material and blood components that define the membrane’s bio(incompatibility. Given the high concentration of plasma proteins and the complexity of structural functional relationships of this class of molecules, the performance of a membrane is highly influenced by its interaction with the plasma protein repertoire. Proteomic investigations have been increasingly applied to describe the protein uremic milieu, to compare the blood purification efficiency of different dialyzer membranes or different extracorporeal techniques, and to evaluate the adsorption of plasma proteins onto hemodialysis membranes. In this article, we aim to highlight investigations in the hemodialysis setting making use of recent developments in proteomic technologies. Examples are presented of why proteomics may be helpful to nephrology and may possibly affect future directions in renal research.

    Griffin, Timothy J.

    2014-06-01

    Human saliva contains a rich mixture of biomolecules. Proteins are a major component of this mixture. Given their role as the molecular effectors within biological systems, ranging from catalysis to transport to structure, proteins have great potential as biomarkers of health and disease. The ability to collect these salivary biomarkers easily using non-invasive means makes saliva proteins even more attractive for diagnostic applications. Thousands of proteins are now to be known to be present in human saliva - discovered using proteomic technologies. Emerging technologies are now making it possible to go beyond large-scale cataloging of salivary proteins. These include approaches to catalog protein contributions from the community of microorganisms residing in the oral cavity (metaproteomics) that may reflect the health state of the human host. New mass spectrometry-based proteomics methods are also emerging, shifting the emphasis from large-scale discovery experiments to hypothesis-driven assays for profiling proteins of interest within saliva, enabling validation of their association with specific health conditions. This paper provides a brief overview of efforts to catalog the proteome of human saliva. Recent developments making possible characterization of the metaproteome of human saliva will be discussed, and technologies driving new mass spectrometry-based assays for targeted analysis of proteins within complex samples, such as saliva.

    2014-10-01

    Cervical spondylotic myelopathy (CSM) is a common condition. Uninstrumented laminectomy may be complicated by postoperative instability, whereas anterior or posterior decompression with fusion may be associated with stiffness and adjacent segment disease. Cervical laminoplasty, initially oriented towards pediatric patients and ossification of the posterior longitudinal ligament, becomes an interesting surgical alternative to decompress and reconstruct cervical anatomy without fusion. Eighteen patients (12 men, 6 women), mean age 64.2 who presented with CSM were treated surgically using multilevel laminoplasty, and reviewed after 1 month, 6 months, 1 year and 2 years. Clinical evaluation was performed based on the Benzel-JOA and Nurick scores. The preoperative mean Benzel-JOA score was 13.55; Preoperative mean Nurick score was 1.88. Preoperative MRI was carried-out in 16/18 patients. Intramedullary hyperintensity in T2 was observed in 6 patients. The operation was performed on 2 levels (4 patients) 3 levels (11 patients) and 4 levels (3 patients). We used the open-door hinged laminoplasty technique, using metallic implants, without bone graft. At one month FU, mean JOA score was 15.44, and Nurick dropped to 1.05. At 6 months, mean JOA was 16.28 and Nurick was 0.71. At one year, the mean JOA score was 16.16, and Nurick was 0.83. At 2 years, mean JOA was 17.5, and Nurick was 0.25. One infection, one dural tear and one transient episode of C5 paresthesia were observed. We conclude that spinal cord decompression by open-door laminoplasty for CSM allows significant clinical improvement observed progressively in the two years following surgery. PMID:25239380

    1984-01-01

    Results obtained in 43 Rheumatoid arthritis (RA) patients with cervical myelopathy are described; all patients showed several alarm signs together with neurological disturbances. Thirty-four cases were operable; nine patients were not operated upon for various reasons (refusal, and general condition). In the surgically treated patients, the changes were localized in the C1-C2 area (n = 20), in the area below C2 (n = 5), or in both (n = 9). The patients were put on skull traction pre- and post-operatively and nursed on a circo-electric bed. Pre-operatively, the duration of traction varied from a few days to weeks (mean 3 weeks). Post-operatively, the patients were given continuous skull traction for 2 1/2-3 months. This procedure yielded neurological improvement and a stable graft in all but two patients. On follow-up, recurrence of neurological complaints was seen in nine patients, in four due to a new slip at a lower level. Three of these cases were reoperated with good results. Twenty-three patients have died: four 'early' (one pre-operatively and three within 6 weeks post-operatively) and 19 'late'. The mean duration of follow-up was 4.5 years. In those who died 'late', the cause of death was due to the effects of an unstable graft in two cases and in the others the causes were not related to changes in the cervical spine. In the 10 patients who are still alive the mean duration of follow-up is 5 years. The nine patients who were not operated upon all died within a year, 4 of them due to consequences of cord compression. If cervical spondylodesis is feasible in an RA patient with myelopathy, the procedure is advocated. PMID:6529877

    Full Text Available Objective: The most common used technique for posterolateral cervical disc herniations is anterior approach. However, posterior cervical laminotoforaminomy can provide excellent results in appropriately selected patients with foraminal stenosis in either soft disc prolapse or cervical spondylosis. The purpose of this study was to present the clinical outcomes following posterior laminoforaminotomy in patients with radiculopathy. Materials and Methods: We retrospectively evaluated 35 patients diagnosed with posterolateral cervical disc herniation and cervical spondylosis with foraminal stenosis causing radiculopathy operated by the posterior cervical keyhole laminoforaminotomy between the years 2010 and 2015. Results: The file records and the radiographic images of the 35 patients were assessed retrospectively. The mean age was 46.4 years (range: 34-66 years. Of the patients, 19 were males and 16 were females. In all of the patients, the neurologic deficit observed was radiculopathy. The posterolaterally localized disc herniations and the osteophytic structures were on the left side in 18 cases and on the right in 17 cases. In 10 of the patients, the disc level was at C5-6, in 18 at C6-7, in 2 at C3-4, in 2 at C4-5, in 1 at C7-T1, in 1 patient at both C5-6 and C6-7, and in 1 at both C4-5 and C5-6. In 14 of these 35 patients, both osteophytic structures and protruded disc herniation were present. Intervertebral foramen stenosis was present in all of the patients with osteophytes. Postoperatively, in 31 patients the complaints were relieved completely and four patients had complaints of neck pain and paresthesia radiating to the arm (the success of operation was 88.5%. On control examinations, there was no finding of instability or cervical kyphosis. Conclusion: Posterior cervical laminoforaminotomy is an alternative appropriate choice in both cervical soft disc herniations and cervical stenosis.

    Objective: The most common used technique for posterolateral cervical disc herniations is anterior approach. However, posterior cervical laminotoforaminomy can provide excellent results in appropriately selected patients with foraminal stenosis in either soft disc prolapse or cervical spondylosis. The purpose of this study was to present the clinical outcomes following posterior laminoforaminotomy in patients with radiculopathy. Materials and Methods: We retrospectively evaluated 35 patients diagnosed with posterolateral cervical disc herniation and cervical spondylosis with foraminal stenosis causing radiculopathy operated by the posterior cervical keyhole laminoforaminotomy between the years 2010 and 2015. Results: The file records and the radiographic images of the 35 patients were assessed retrospectively. The mean age was 46.4 years (range: 34-66 years). Of the patients, 19 were males and 16 were females. In all of the patients, the neurologic deficit observed was radiculopathy. The posterolaterally localized disc herniations and the osteophytic structures were on the left side in 18 cases and on the right in 17 cases. In 10 of the patients, the disc level was at C5-6, in 18 at C6-7, in 2 at C3-4, in 2 at C4-5, in 1 at C7-T1, in 1 patient at both C5-6 and C6-7, and in 1 at both C4-5 and C5-6. In 14 of these 35 patients, both osteophytic structures and protruded disc herniation were present. Intervertebral foramen stenosis was present in all of the patients with osteophytes. Postoperatively, in 31 patients the complaints were relieved completely and four patients had complaints of neck pain and paresthesia radiating to the arm (the success of operation was 88.5%). On control examinations, there was no finding of instability or cervical kyphosis. Conclusion: Posterior cervical laminoforaminotomy is an alternative appropriate choice in both cervical soft disc herniations and cervical stenosis.

  5. Diagnosis of cervical disc disease

    International Nuclear Information System (INIS)

    High resolution CT easily localized lesions including soft tissues of the bone such as disc protrusion and thickening of the yellow ligament. In all cases, myelography demonstrated compression of the nerve roots of the spinal cord which corresponded to CT findings at the level where plain CT revealed a lesion. However, CT metrizamide myelography demonstrated the lesion more clearly than did conventional myelography. CT metrizamide myelography also outlined compression of the nerve roots satisfactorily and demonstrated compressed findings of the spinal cord in the dynamic study. Thus, high resolution CT was useful for screening of cervical disc disease, and CT metrizamide myelography, for identification of lesions of the nerve roots. (Chiba, N.)

    Objective:To measure the expression pattern ofSTAT2 in cervical cancer initiation and progression in tissue sections from patients with cervicitis, dysplasia, and cervical cancer. Methods:Antibody against humanSTAT2 was confirmed by plasmids transient transfection andWestern blot.Immunohistochemistry was used to detectSTAT2 expression in the cervical biopsies by using the confirmed antibody againstSTAT2 as the primary antibody.Results:It was found that the overall rate of positiveSTAT2 expression in the cervicitis, dysplasia and cervical cancer groups were38.5%,69.4% and76.9%, respectively.TheSTAT2 levels are significantly increased in premalignant dysplasia and cervical cancer, as compared to cervicitis(P<0.05). Noticeably,STAT2 signals were mainly found in the cytoplasm, implying thatSTAT2 was not biologically active.Conclusions:These findings reveal an association between cervical cancer progression and augmentedSTAT2 expression.In conclusion,STAT2 increase appears to be an early detectable cellular event in cervical cancer development.

    Cervical spinal cord injury is a rare but serious complication after general anesthesia. The risk factors include traumatic cervical injury, cervical spine instability, and difficult airway management. It has also occurred in the absence of cervical instability. Here we report a patient who had a history of intermittent neck pain without numbness. Preoperative radiologic examinations showed degenerative changes in the cervical spine. She developed progressive tingling and numbness in her limbs after thyroidectomy under general anesthesia. Magnetic resonance imaging showed a cervical disc protruding into the canal at C5-C6, which was considered to be induced by surgical positioning. She recovered after anterior cervical decompression and internal fixation surgery. PMID:23828450

    Full Text Available The experience of treatment for precancer and early cervical cancer by photodynamic therapy in 12 patients with primary diagnosis H-SIL (CIN II–III and cancer in situ is described. Chlo-rine photosensitizer Photolon was given intravenously at a dose of 0.75–1.15 mg/kg body weight. 2.5 h later the treatment with polyposition laser exposure (light dose – 150 J/cm2, light power density – 400–500 mW/cm2 was made. Thirty days later conization of the cervix with endocervical curettage assessing therapeutic response of cervical tumor tissue was per-formed. According to histological data complete response was in 4 patients, minute foci of CIN I were determined in 7 patients, 1 patient had foci of CIN II. 8 of 10 HPV-positive patients had complete eradication of HPV after treatment. There were no serious adverse events after light exposure. Marked therapeutic response, high anti-viral activity and good feasibility allow to consider photodynamic therapy as alternative organ-sparing treatment of early cancer and pre-cancer of cervix.

    2013-01-01

    Persistent infection with high-risk types of human papillomavirus(HPV) is known to cause cervical cancer; however,additional genetic and epigenetic alterations are required for progression from precancerous disease to invasive cancer.DNA methylation is an early and frequent molecular alteration in cervical carcinogenesis.In this review,we summarize DNA methylation within the HPV genome and human genome and identify its clinical implications.Methylation of the HPV long control region (LCR) and L1 gene is common during cervical carcinogenesis and increases with the severity of the cervical neoplasm.The L1 gene of HPV16 and HPV18 is consistently hypermethylated in invasive cervical cancers and can potentially be used as a clinical marker of cancer progression.Moreover,promoters of tumor suppressor genes (TSGs) involved in many cellular pathways are methylated in cervical precursors and invasive cancers.Some are associated with squamous cell carcinomas,and others are associated with adenocarcinomas.Identification of methylated TSGs in Pap smear could be an adjuvant test in cervical cancer screening for triage of women with high-risk HPV,atypical squamous cells of undetermined significance,or low grade squamous intraepithelial lesion (LSIL).However,consistent panels must be validated for this approach to be translated to the clinic.Furthermore,reversion of methylated TSGs using demethylating drugs may be an alternative anticancer treatment,but demethylating drugs without toxic carcinogenic and mutagenic properties must be identified and validated.

    2016-01-01

    The new German S3 guideline 'Prevention of Cervical Cancer' published in 2016 is based on the latest available evidence about cervical cancer screening and treatment of cervical precancer. Large randomized controlled trials indicate that human papillomavirus (HPV)-based screening may provide better protection against cervical cancer than cytology alone through improved detection of premalignant disease in the first screening round prior to progression. Therefore, women aged 30 years and older should preferably be screened with HPV testing every 3-5 years (cytology alone every 2 years is an acceptable alternative). Co-testing is not recommended. Screening should start at 25 years using cytology alone every 2 years. The preferred triage test after a positive HPV screening test is cytology. Women positive for HPV 16 and HPV 18 should receive immediate colposcopy. Another alternative triage method is p16/Ki-67 dual stain cytology. The mean yearly participation rate in Germany is between 45 and 50%. Offering devices for HPV self-sampling has the potential to increase participation rates in those women who are at higher risk of developing cervical cancer. Regarding primary prevention, the 9-valent vaccine may provide protection against up to 85% of cervical intraepithelial neoplasia (CIN) 3 and 90% of cervical cancer, and is available in Europe as a 2-dose schedule from May 2016.

  5. Cervical neurofibromas in children with NF-1

    International Nuclear Information System (INIS)

    Background. Children with neurofibromatosis type 1 (NF1) are at increased risk of developing plexiform neurofibroma throughout the body, including the cervical soft tissues. However, the incidence of cervical soft tissue tumors and the value of screening MR for children with NF1 are not known. Purpose. The purposes of this study were to determine the incidence and clinical significance of cervical tumors seen on MR imaging in children with NF1. Materials and methods. A retrospective review of the brain and orbit MR with cervical images obtained on 95 children who meet the NIH consensus criteria for NF1 and who are followed at our neurofibromatosis clinic was carried out. Results. Cervical tumors were found on MR imaging in 21 of 95 (22 %) children. Of 21 children with cervical tumors, 14 children were determined to be surgical candidates. In nine children, MR imaging altered the clinical management by demonstrating tumors for which surgery was indicated, but the tumors were not suspected prior to MR imaging. Conclusion. Cervical tumors are commonly seen in children with NF1. MR imaging may demonstrate a significant number of tumors that require surgery, but were not suspected prior to MR imaging. (orig.)

    Cervical vertigo refers to a syndrome with a chief complaint of vertigo arising from cervical verteprae discomfort. In general, cervical vertigo is correlated with but not always caused by cervical spondylopathy,which mainly includes vertebral arterial and sympathetic cervical spondylosis. The vertebral artery insufficiency caused by compression from lateral displacement of the intervertebral dise is very rare, while the sympathetic cervical spondylosis caused by the vertebral instability is much more common. Rigorous criteria have been developed for diagnosis of the latter. Conservative therapy is mainly recommended for treatment of cervical vertigo.%颈性眩晕通常与颈椎病有关,但不一定完全由颈椎病所致.与颈性眩晕有关的主要是椎动脉型和交感型颈椎病.由椎间盘侧突压迫导致的椎动脉供血不足非常罕见,由椎体不稳引起的交感型颈椎病较多,但后者也有其严格的诊断标准.治疗以保守治疗为主.

    Objective:We evaluated a new hypothesis of acetaminophen therapy to reduce the necessity of imaging in patients with probable traumatic cervical spine injury.Methods:Patients with acute blunt trauma to the neck and just posterior midline cervical tenderness received acetaminophen (15 mg/kg) intravenously after cervical spine immobilization.Then,all the patients underwent plain radiography and computerized tomography of the cervical spine.The outcome measure was the presence of traumatic cervical spine injury.Sixty minutes after acetaminophen infusion,posterior midline cervical tendemess was reassessed.Results:Of 1 309 patients,41 had traumatic cervical spine injuries based on imaging.Sixty minutes after infusion,posterior midline cervical tenderness was eliminated in 1 041 patients,none of whom had abnormal imaging.Conclusion:Patients with cervical spine trauma do not need imaging if posterior midline cervical tendemess is eliminated after acetaminophen infusion.This analgesia could be considered as a diagnostic and therapeutic intervention.

  8. Diagnosis and outcome of cervical artery dissection

    Directory of Open Access Journals (Sweden)

    Divjak Ivana

    2011-01-01

    Full Text Available Introduction. Spontaneous dissection of the cervical artery is a rare non-atherosclerotic vascular disease of unknown aetiology and unclear pathogenesis that may be a cause of ischemic stroke in young adults. Diagnosis. Precise diagnosis of dissection of the cervical artery - carotid or vertebral - is possible with cervical axial magnetic resonance imaging and magnetic resonance angiography. Treatment. The recommended treatment in the acute phase of cervical artery dissection is anticoagulant or antithrombotic therapy, aimed at preventing a primary or recurrent ischemic event. There have been as yet no results of randomized controlled studies comparing efficacy of both treatments. An ongoing randomized multicentre study is expected to provide answers about the effects of these treatments in cervical artery dissection. Outcome. Complete resolution of arterial abnormalities is achieved in around 46% of stenoses, 33% of occlusions, and 12% of dissecting aneurysms. Recurrent events. Recurrence of cerebral ischemia and cervical artery dissection seems to be rare, although some data suggest that early ischemic and late cervical artery dissection recurrences could be underestimated. Mortality and functional outcome. In comparison with other causes of stroke in young adults, the functional outcome of cervical artery dissection is good in contrast to its socio-professional effects, which may be unsatisfactory. The mortality rate of cervical artery dissection is low, although it may be underestimated since some patients with malignant infarction die before the diagnosis is established. Conclusion. Further research is warranted to improve our understanding of the underlying pathophysiology, to assess the long-term outcome, and ultimately to provide treatment and prevention strategies.

  9. Radiological evaluation of the cervical spinal trauma

    International Nuclear Information System (INIS)

    Acute injuries of the cervical spine are the most common causes of severe disability following trauma, yet the diagnosis of these injuries are often delayed and the treatment, inadequate. Traumatic injuries of the cervical spine are diagnosed by radiological examinations. And complete evaluations of bony structures and soft tissue changes on conventional radiograms are very important for determining the therapeutic plans and prognoses of the injuries patients. During the period of 5 years from June 1976 to May 1981, the radiological and clinical evaluation had been made on 38 patients suffered from acute cervical spinal injuries which were confirmed by the radiological examinations. The results were as follows. 1. Age distribution of total 38 patients was broad ranging from 19 years to 72 years. 2. The most common cause of injury was traffic accident, next fall down, other accident respectively. 3. Levels of the cervical spinal injuries were as follows: Upper cervical spine in 15.8%, lower cervical spine in 84.2%, and the most common injuries level was C 5. Most of the lower cervical spinal injuries were located in the vertebral body and spinous process. 4. Anatomical sites of the cervical spinal injuries were as follows; vertebral body in 55.5%, spinous process in 23.7%, neural arch in 15.8%, and locked facet in 18.4%, etc. 5. Most of the patients with severe mental changes were injuries in upper cervical spine rather than lower. And most of the patients with quadriplegia or paraplegia were shown marked disruption of spinal canal

    Full Text Available Cervical cancers form the second highest number of female cancers in Malaysia, imposing a substantial amount of cost burden on its management. However, an estimation of cost burden of abnormal smears, cervical pre-invasive and invasive diseases needs to be done to show how much spending has been allocated to the problem. An expert panel committee came up with the clinical pathway and management algorithm of  cervical pre invasive and invasive diseases from July-December 2006 Malaysia. An activity based costing for each clinical pathway was done. Results were converted to USD. The cost of managing pre-invasive cervical cancers stage is USD 420,150 (Range: USD 197,158-879,679. Management of invasive cancer (new cases costs USD 51,533,233.44 (Range: USD 32,405,399.69 - USD 129,014,768.40. The cost of managing existing cases is USD 17,005,966.87 (Range: USD 10,693,781.90 - USD  28,901,587.12. The total cost of managing cervical cancers by health care providers in a public setting is around USD 75,888,329.45 (Range: USD 48,083,804.60 - USD 48,083,804.60. The outcome of this study has shown that preventive modalities such as screening have only contributed to 10.3 % of the total management cost of cervical cancer. The major cost contribution (67% came from treatment of invasive cancer especially at more advanced stages of cancer, followed by treatment of existing cases (22% and lastly on pre-invasive disease (0.6%. This study revealed that proportion of preventive modality in this country was still low, and the major cost came from actual treatment cost of cervical cancer. Therefore, heightened public cervical cancer screening in the country is needed. (Med J Indones 2008; 17: 272-80Keywords: cervical cancers, pre invasive disease, HPV vaccination

    2014-12-01

    Full Text Available Background: Cervical radiculopathy is a dysfunction of nerve root of the cervical spine where C6& C7 nerve roots are the most commonly affected. It encompasses important symptoms other than pain, such as paresthesia, numbness and muscle weakness in dermatomal or myotomal distribution of an affected nerve root. A multitude of physical therapy interventions have been proposed to be effective in the management of cervical radiculopathy, including mechanical cervical traction, manipulation, therapeutic exercises and TENS. Studies to find out the effectiveness of TENS versus Intermittent Cervical Traction among patients with Cervical Radiculopathy are sparse. Hence the present study was undertaken to find out and compare effectiveness of TENS versus Intermittent Cervical Traction a newer technique towards betterment in treatment of cervical radiculopathy patients. Methodology: 30 patients from Baroda association for the blind (Lions club of Baroda, Subhanpura & Sushrut Physiotherapy Clinic, Akota were chosen based on the inclusion and exclusion criteria. Group A comprised of 15 people with cervical radiculopathy were given TENS with Isometric neck exercises and active neck movements. Group B comprised of 15 people with cervical radiculopathy were given Intermittent Cervical Traction with Isometric neck exercise and active neck movements. VAS Scale & Neck Disability Index (NDI were used as outcome measures pre & post treatment. Results: The pre test evaluation showed that, there is no significant difference (P> 0.05 between the two groups for all the variables measured. The post-test evaluation of both groups showed a very high significance (P< 0.05 within the group for all the outcome measurements. A post-test comparison of measured variables, between the groups showed that the Group A demonstrated a statistically significant (P< 0.05 reduction in pain and Neck Disability Index. Conclusion: From the above study concluded that TENS was more effective

    International Nuclear Information System (INIS)

    A retrospectivce analysis of pediatric admissions over 10 years revealed 29 patients with cervical spine injuries. Eleven patients were below 12 years of age, and 10 of these had injuries involving C1, C2 or the occipitoatlantal articulation. Eighteen patients were between 12 and 16 years of age with injuries distributed throughout the cervical spine similar to injuries in the adult population. Our results suggest that teenagers with suspected cervical injuries are best evaluated by an adult radiographic series including trauma oblique views. In younger patients, careful evaluation of occipitoatlantoaxial alignment and the prevertebral soft tissues is required for diagnosis and selection of additional imaging evaluation. (orig.)

    Actinomyces naeslundii, an oral biofilm bacterium of, can be cured using intravenous piperacillin, clindamycin, and surgery. We report a case of cervical actinomycosis due to Actinomyces naeslundii. A 56-year-old man seen for right cervical swelling had undergone dental work. Computed tomography indicated an abscess, from which we aspirated pus using a needle. Although no sulfur granules were found, pus yielded Actinomyces naeslundii. This case is, to our knowledge, the first reported in Japan of cervical actinomycosis due to A. naeslundii. PMID:21838058

    Full Text Available To evaluate the cervical spine rotation movement is quiet harder than other joints. Configuration and arrangement of current goniometers and devices is not always practic in clinics and some methods are quiet expensive. The cervical axial rotation goniometer designed by the authors is consists of five pieces (head apparatus, chair, goniometric platform, eye pads and camera. With this goniometer design a detailed evaluation of cervical spine range of motion can be obtained. Besides, measurement of "joint position sense" which is recently has rising interest in researches can be made practically with this goniometer.

    We present the case of a 44-year-old man who complained of cervical pain. He was treated with physiotherapy and analgetics. Because of persistent pain, computed tomography (CT) scan and MRI were performed. They revealed an osteolytic destruction of the fourth cervical vertebra. The patient was treated surgically for removal of the tumor and stabilization of his cervical spine. Histology of the osteolytic material led to the diagnosis of an eosinophilic granuloma of the cervical spine. This case report describes the incidence, clinical significance, background and therapy of an eosinophilic granuloma of the spine. PMID:15120180

  3. Distracted cervical spinal fusion for management of caudal cervical spondylomyelopathy in large-breed dogs

    International Nuclear Information System (INIS)

    Using an autogenous bone graft (obtained from the iliac crest), 4-mm cancellous bone screws, and polymethylmethacrylate, a distracted cervical spinal fusion technique was performed on 10 dogs with myelographic evidence of caudal cervical spondylomyelopathy. All dogs had evidence of dynamic soft tissue spinal cord compression, as indicated by flexion, extension, and traction myelographic views. Of the 10 dogs, 4 previously had undergone surgery by use of ventral slot or cervical disk fenestration techniques, and their neurologic status had deteriorated after the original surgery. Preoperative neurologic status of the 10 dogs included nonambulatory tetraparesis (n = 5), severe ataxia with conscious proprioceptive deficits (n = 2), and mild ambulatory ataxia with conscious proprioceptive deficits (n = 3). Five dogs had signs of various degrees of cervical pain. Clinical improvement was observed in 8 of 10 dogs--either improved neurologic status or elimination of cervical pain. Implant loosening developed in 3 dogs; 2 of them were euthanatized because of lack of neurologic improvement. Radiographic evidence of bony cervical fusion was observed during a 9- to 24-week period in 6 of the 8 surviving dogs. The distracted cervical fusion technique appears to be a valid surgical procedure to manage cervical spondylomyelopathy in those dogs in which the lesions are limited to one cervical intervertebral disk space

    Koenig, Rainer; Bergander, S.

    1990-11-01

    In the context of the early recognition of cervical cancer the cytology has to detect tumor positive cases among a bulk of un suspicious specimens. Unfortunately there is a group of cases with a vague diaxosis, the so called PAP-ill-group. There are many reasons for the recent impossibility of a safe conclusion from the PAP-Ill-smears to their histological diagnoses (Pig. 1). Today for an exact statement a cone biopsy and a microscopical investigation of its histological sections for such caseS are necessary. That results in a high medical and economical expense and, last not least, that means a higher risk of complications and of future family planning problems for the women affected.

  9. Imaging advances in upper cervical vertebral disease

    International Nuclear Information System (INIS)

    Upper cervical vertebral has complex anatomic structure and some diseases may involve this vital center area of human body. Most of the diseases, such as trauma, malformation, and degeneration, need to be treated with surgery to recover the function of cervical vertebral. The accurate evaluation is crucial before and after the surgery. In the past few years, CT, MRI, and ultra-sound play important roles in the evaluation of upper cervical vertebral diseases and planning treatment. Comprehensive evaluation with multidisciplinary approach is advocated. In this paper we reviewed the anatomy and clinic treatments; summarized the latest imaging advances in upper cervical vertebral disease; discussed the perspective of comprehensive evaluation with multidisciplinary approach.

    International Nuclear Information System (INIS)

    Five horses, weighing 337 to 400 kg, were used in this research, one of them being used as control. Cervical myelography with iohexol (Omnipaque) was performed on four horses tranquilized with flunitrazepan before induction of anesthesia with sodium thiopental. Anesthesia was maintained with fluothane and oxygen. Cerebrospinal fluid (CSF) was analysed before and after an injection of ioxheol into the subarachnoid space. The animals received 25 to 50 ml of iohexol, after removal of 20 ml cerebrospinal fluid. Radiographies were taken with the horses at lateral recumbency, and the cranial, central and caudal regions of the cervical spine being focalized. No significant changes occurred in the cerebrospinal fluid after injecting the contrast medium. Pathologic changes were not found by gross or microscopic examination of the brain and the cervical spinal cord. Radiographies of good to excellent image quality were obtained. At autopsy, radiographic diagnosis of cervical vertebral instability was confirmed in the animal that had pelvic limb ataxia

On examination, the infant had spastic paraplegia. Magnetic resonance (MR imaging of the cervical spine showed an epidural hematoma extending from the fourth cervical (C4 to the first dorsal (D1 vertebral level with cord compression. The patient had no bleeding disorder on investigation. He underwent cervical laminoplasty at C6 and C7 levels. The epidural hematoma was evacuated. The cervical cord started pulsating immediately. Postoperatively, the patient′s paraplegia improved dramatically in 48 hours. According to the author′s literature search, only seven cases of post-traumatic epidural hematoma have been reported in pediatric patients, and our patient is the youngest. The present case report discusses the etiopathology, presentation, and management of this rare case.

  14. Radiosensitizers in cervical cancer. Cisplatin and beyond

    International Nuclear Information System (INIS)

    Cervical cancer continues to be a significant health burden worldwide. Globally, the majority of cancers are locally advanced at diagnosis; hence, radiation remains the most frequently used therapeutical modality. Currently, the value of adding cisplatin or cisplatin-based chemotherapy to radiation for treatment of locally advanced cervical cancer is strongly supported by randomized studies and meta-analyses. Nevertheless, despite these significant achievements, therapeutic results are far from optimal; thus, novel therapies need to be assayed. A strategy currently being investigated is the use of newer radiosensitizers alone or in combination with platinum compounds. In the present work, we present preclinical information on known and newer cytotoxic agents as radiosensitizers on cervical cancer models, as well as the clinical information emanating from early phase trials that incorporate them to the cervical cancer management. In addition, we present the perspectives on the combined approach of radiation therapy and molecular target-based drugs with proven radiosensitizing capacity

    BACKGROUND: Due to its extraordinarily fast economic and social transition, virtually closed borders before 1940 and, moreover, that 85% of the population has the distinctive genetics of the Inuit, Greenland is a very interesting country to study cervical cancer from a historical perspective....... Nevertheless, little has been reported about long-term cancer trends in Greenland. Our aim was to describe and interpret the incidence of cervical cancer from 1950 to 2009. MATERIAL AND METHODS: We systematically searched PubMed for articles reporting the incidence of cervical cancer in Greenland. We...... supplemented this with data for 1980-2009 obtained from the Chief Medical Officer of Greenland. RESULTS: Incidence of cervical cancer was around 10 per 100 000 women (age-standardised, world population, ASW) in the 1950s, 30 per 100 000 in the 1960s, and in the 1980s around 60 per 100 000.

    Optical methods and proteomics investigations are becoming promising approaches for early detection of many diseases, which remain clinically silent for long periods. We have used efficient High Performance Liquid Chromatography (HPLC) separation combined with highly sensitive laser induced fluorescence detection of proteins present in clinical samples for diagnostic applications in cervical cancer. The protein profile and the fluorescence of individual proteins were simultaneously recorded using our HPLC-LIF system. Protein profiles (Chromatogram) of serum from normal male and female volunteers with and without tobacco habits, and malignant serum samples were studied. Protein profiles were also recorded for lysates of exfoliated cells collected from Pap smear of normal and cancer patients. The protein profile patterns were subjected to Principal component Analysis. Discrimination of normal and malignant samples were achieved with very high sensitivity and specificity.

  3. Relationship between selected indoor volatile organic compounds, so-called microbial VOC, and the prevalence of mucous membrane symptoms in single family homes

    International Nuclear Information System (INIS)

    Microorganisms are known to produce a range of volatile organic compounds, so-called microbial VOC (MVOC). Chamber studies where humans were exposed to MVOC addressed the acute effects of objective and/or subjective signs of mucosal irritation. However, the effect of MVOC on inhabitants due to household exposure is still unclear. The purpose of this epidemiological study was to measure indoor MVOC levels in single family homes and to evaluate the relationship between exposure to them and sick building syndrome (SBS). All inhabitants of the dwellings were given a self-administered questionnaire with standardized questions to assess their symptoms. Air samples were collected and the concentrations of eight selected compounds in indoor air were analyzed by gas chromatography/mass spectrometry - selective ion monitoring mode (GC/MS-SIM). The most frequently detected MVOC was 1-pentanol at a detection rate of 78.6% and geometric mean of 0.60 μg/m3. Among 620 participants, 120 (19.4%) reported one or more mucous symptoms; irritation of the eyes, nose, airway, or coughing every week (weekly symptoms), and 30 (4.8%) reported that the symptoms were home-related (home-related symptoms). Weekly symptoms were not associated with any of MVOC, whereas significant associations between home-related mucous symptoms and 1-octen-3-ol (per log10-unit: odds ratio (OR) 5.6, 95% confidence interval (CI): 2.1 to 14.8) and 2-pentanol (per log10-unit: OR 2.3, 95% CI: 1.0 to 4.9) were obtained after adjustment for gender, age, and smoking. Associations between home-related symptoms and 1-octen-3-ol remained after mutual adjustment. However, concentrations of the selected compounds in indoors were lower than the estimated safety level in animal studies. Thus, the statistically significant association between 1-octen-3-ol may be due to a direct effect of the compounds or the associations may be being associated with other offending compounds. Additional studies are needed to evaluate these

    2012-11-01

    To complement the recent genomic sequencing of Chinese hamster ovary (CHO) cells, proteomic analysis was performed on CHO cells including the cellular proteome, secretome, and glycoproteome using tandem mass spectrometry (MS/MS) of multiple fractions obtained from gel electrophoresis, multidimensional liquid chromatography, and solid phase extraction of glycopeptides (SPEG). From the 120 different mass spectrometry analyses generating 682,097 MS/MS spectra, 93,548 unique peptide sequences were identified with at most 0.02 false discovery rate (FDR). A total of 6164 grouped proteins were identified from both glycoproteome and proteome analysis, representing an 8-fold increase in the number of proteins currently identified in the CHO proteome. Furthermore, this is the first proteomic study done using the CHO genome exclusively, which provides for more accurate identification of proteins. From this analysis, the CHO codon frequency was determined and found to be distinct from humans, which will facilitate expression of human proteins in CHO cells. Analysis of the combined proteomic and mRNA data sets indicated the enrichment of a number of pathways including protein processing and apoptosis but depletion of proteins involved in steroid hormone and glycosphingolipid metabolism. Five-hundred four of the detected proteins included N-acetylation modifications, and 1292 different proteins were observed to be N-glycosylated. This first large-scale proteomic analysis will enhance the knowledge base about CHO capabilities for recombinant expression and provide information useful in cell engineering efforts aimed at modifying CHO cellular functions.

  5. Visualizing Meta-Features in Proteomic Maps

    2011-07-01

    Full Text Available Abstract Background The steps of a high-throughput proteomics experiment include the separation, differential expression and mass spectrometry-based identification of proteins. However, the last and more challenging step is inferring the biological role of the identified proteins through their association with interaction networks, biological pathways, analysis of the effect of post-translational modifications, and other protein-related information. Results In this paper, we present an integrative visualization methodology that allows combining experimentally produced proteomic features with protein meta-features, typically coming from meta-analysis tools and databases, in synthetic Proteomic Feature Maps. Using three proteomics analysis scenarios, we show that the proposed visualization approach is effective in filtering, navigating and interacting with the proteomics data in order to address visually challenging biological questions. The novelty of our approach lies in the ease of integration of any user-defined proteomic features in easy-to-comprehend visual representations that resemble the familiar 2D-gel images, and can be adapted to the user's needs. The main capabilities of the developed VIP software, which implements the presented visualization methodology, are also highlighted and discussed. Conclusions By using this visualization and the associated VIP software, researchers can explore a complex heterogeneous proteomics dataset from different perspectives in order to address visually important biological queries and formulate new hypotheses for further investigation.

    Legumes are the major sources of food and fodder with strong commercial relevance, and are essential components of agricultural ecosystems owing to their ability to carry out endosymbiotic nitrogen fixation. In recent years, legumes have become one of the major choices of plant research. The legume proteomics is currently represented by more than 100 reference maps and an equal number of stress-responsive proteomes. Among the 48 legumes in the protein databases, most proteomic studies have been accomplished in two model legumes, soybean, and barrel medic. This review highlights recent contributions in the field of legume proteomics to comprehend the defence and regulatory mechanisms during development and adaptation to climatic changes. Here, we attempted to provide a concise overview of the progress in legume proteomics and discuss future developments in three broad perspectives: (i) proteome of organs/tissues; (ii) subcellular compartments; and (iii) spatiotemporal changes in response to stress. Such data mining may aid in discovering potential biomarkers for plant growth, in general, apart from essential components involved in stress tolerance. The prospect of integrating proteome data with genome information from legumes will provide exciting opportunities for plant biologists to achieve long-term goals of crop improvement and sustainable agriculture.

  7. Network-based analysis of proteomic profiles

    KAUST Repository

    Wong, Limsoon

    2016-01-26

    Mass spectrometry (MS)-based proteomics is a widely used and powerful tool for profiling systems-wide protein expression changes. It can be applied for various purposes, e.g. biomarker discovery in diseases and study of drug responses. Although RNA-based high-throughput methods have been useful in providing glimpses into the underlying molecular processes, the evidences they provide are indirect. Furthermore, RNA and corresponding protein levels have been known to have poor correlation. On the other hand, MS-based proteomics tend to have consistency issues (poor reproducibility and inter-sample agreement) and coverage issues (inability to detect the entire proteome) that need to be urgently addressed. In this talk, I will discuss how these issues can be addressed by proteomic profile analysis techniques that use biological networks (especially protein complexes) as the biological context. In particular, I will describe several techniques that we have been developing for network-based analysis of proteomics profile. And I will present evidence that these techniques are useful in identifying proteomics-profile analysis results that are more consistent, more reproducible, and more biologically coherent, and that these techniques allow expansion of the detected proteome to uncover and/or discover novel proteins.

    Full Text Available Background: Cervical disc replacement is becoming an increasingly popular treatment option for cervical myelopathy. It retains motion at the affected segment, unlike anterior cervical discectomy and fusion. The aim of this study is to assess the outcomes of a series of patients who underwent Activ C disc replacement for cervical myelopathy. Materials and Methods: A series of patients at the above Trust with clinical and radiological evidence of cervical myelopathy who were suitable for cervical disc replacement from 2007 to 2009 were included. Implants were inserted by one of two consultant surgeons {IMS, MO′M}. Patients were assessed preoperatively and at six, 12 and 24 months, postoperatively, with a visual analogue score (VAS for neck and arm pain severity and frequency, the Neck Disability Index questionnaire (NDI and the Centre for Epidemiologic Studies Depression questionnaire (CES-D. Results: Ten patients underwent surgery between May 2007 and July 2009, 6 women, and 4 men. Average age was 54 years (40-64. Disc levels replaced were: four at C4-5; eight at C5-6; seven at C6-7. Three patients had one disc replaced, five patients had two discs replaced, and two patients had three discs replaced. The VAS for neck pain improved from 5.9 pre-operatively to 1.4-24 months postoperatively and the VAS arm pain improved from 5.4 to 2.6. The NDI improved from 51% preoperatively to 26.8% at 24 months postoperatively. The CES-D showed a slight increase from 19.5 preoperatively to 21.7 at 24 months, postoperatively. Conclusion: Cervical decompression and disc replacement improves pain and function in patients with cervical myelopathy. This benefit is maintained at 24 months post op, with no cases requiring revision.

    In case of invasive cervical carcinoma several molecular events were reported and these molecular events resulting in multiple genetic abnormalities. In order to control these tumors multiple molecular therapeutic targets are needed with different molecular mechanisms. Unfortunately, these molecular targets were in early stages of development. Because of less degree of success of conventional therapeutics for late stages of cervical cancer and lowering of prognosis of patients there is an inc...

    Thoracic duct cysts are uncommon lesions that most commonly occur in the abdominal and thoracic portion of the thoracic duct: the cervical portion is the rarest location. The main causes of thoracic duct cyst are surgical injuries such as neck dissection and blunt trauma. We report here on a rare case of spontaneous cervical thoracic duct cyst that was noted on ultrasonography and CT. The thoracic duct cyst was confirmed by fine needle aspiration and it was treated by sclerotherapy.

    Full Text Available The inner ear, one of the most complex organs, contains within its bony shell three sensory systems, the evolutionary oldest gravity receptor system, the three semicircular canals for the detection of angular acceleration, and the auditory system - unrivaled in sensitivity and frequency discrimination. All three systems are susceptible to a host of afflictions affecting the quality of life for all of us. In the first part of this review we present an introduction to the milestones of inner ear research to pave the way for understanding the complexities of a proteomics approach to the ear. Minute sensory structures, surrounded by large fluid spaces and a hard bony shell, pose extreme challenges to the ear researcher. In spite of these obstacles, a powerful preparatory technique was developed, whereby precisely defined microscopic tissue elements can be isolated and analyzed, while maintaining the biochemical state representative of the in vivo conditions. The second part consists of a discussion of proteomics as a tool in the elucidation of basic and pathologic mechanisms, diagnosis of disease, as well as treatment. Examples are the organ of Corti proteins OCP1 and OCP2, oncomodulin, a highly specific calcium-binding protein, and several disease entities, Meniere's disease, benign paroxysmal positional vertigo, and perilymphatic fistula.

    Neural stem cells (NSCs) can self-renew and give rise to the major cell types of the CNS. Studies of NSCs include the investigation of primary, CNS-derived cells as well as animal and human embryonic stem cell (ESC)-derived and induced pluripotent stem cell (iPSC)-derived sources. NSCs provide a means with which to study normal neural development, neurodegeneration, and neurological disease and are clinically relevant sources for cellular repair to the damaged and diseased CNS. Proteomics studies of NSCs have the potential to delineate molecules and pathways critical for NSC biology and the means by which NSCs can participate in neural repair. In this review, we provide a background to NSC biology, including the means to obtain them and the caveats to these processes. We then focus on advances in the proteomic interrogation of NSCs. This includes the analysis of posttranslational modifications (PTMs); approaches to analyzing different proteomic compartments, such the secretome; as well as approaches to analyzing temporal differences in the proteome to elucidate mechanisms of differentiation. We also discuss some of the methods that will undoubtedly be useful in the investigation of NSCs but which have not yet been applied to the field. While many proteomics studies of NSCs have largely catalogued the proteome or posttranslational modifications of specific cellular states, without delving into specific functions, some have led to understandings of functional processes or identified markers that could not have been identified via other means. Many challenges remain in the field, including the precise identification and standardization of NSCs used for proteomic analyses, as well as how to translate fundamental proteomics studies to functional biology. The next level of investigation will require interdisciplinary approaches, combining the skills of those interested in the biochemistry of proteomics with those interested in modulating NSC function.

    Cervical cancer is the second most common cause of cancer death in women worldwide and the development of new diagnosis, prognostic, and treatment strategies merits special attention. Although surgery and chemoradiotherapy can cure 80%-95% of women with early stage cancer, the recurrent and metastatic disease remains a major cause of cancer death. Many efforts have been made to design new drugs and develop gene therapies to treat cervical cancer. In recent decades, research on treatment strategies has proposed several options, including the role of HPV E6 and E7 oncogenes, which are retained and expressed in most cervical cancers and whose respective oncoproteins are critical to the induction and maintenance of the malignant phenotype. Other efforts have been focused on antitumor immunotherapy strategies. It is known that during the development of cervical cancer, a cascade of abnormal events is induced, including disruption of cellular cycle control, perturbation of antitumor immune response, alteration of gene expression, and deregulation of microRNA expression. Thus, in this review article we discuss potential targets for the treatment of cervical cancer associated with HPV infection, with special attention to immunotherapy approaches, clinical trials, siRNA molecules, and their implications as gene therapy strategies against cervical cancer development.

    Cervical Cancer is the second most common cancer among women worldwide and the leading cause of cancer mortality of women in developing countries. If detected early and treated adequately, cervical cancer can be virtually prevented. Cervical precursor lesions and invasive cancer exhibit certain morphologic features that can be identified during a visual inspection exam. Digital imaging technologies allow us to assist the physician with a Computer-Aided Diagnosis (CAD) system. In colposcopy, epithelium that turns white after application of acetic acid is called acetowhite epithelium. Acetowhite epithelium is one of the major diagnostic features observed in detecting cancer and pre-cancerous regions. Automatic extraction of acetowhite regions from cervical images has been a challenging task due to specular reflection, various illumination conditions, and most importantly, large intra-patient variation. This paper presents a multi-step acetowhite region detection system to analyze the acetowhite lesions in cervical images automatically. First, the system calibrates the color of the cervical images to be independent of screening devices. Second, the anatomy of the uterine cervix is analyzed in terms of cervix region, external os region, columnar region, and squamous region. Third, the squamous region is further analyzed and subregions based on three levels of acetowhite are identified. The extracted acetowhite regions are accompanied by color scores to indicate the different levels of acetowhite. The system has been evaluated by 40 human subjects' data and demonstrates high correlation with experts' annotations.

    Anterior cervical hypertrichosis is a very rare form of primary localized hypertrichosis. It consists of a tuft of terminal hair on the anterior neck just above the laryngeal prominence. The etiology is still unknown. In this article, we reported a 15-year-old female patient who presented to our clinic with a complaint of hypertrichosis on the anterior aspect of the neck for the last five years. Her past medical history revealed no pathology except for vesicoureteral reflux. On the basis of clinical presentation, our patient was diagnosed with anterior cervical hypertrichosis and she was considered to be a sporadic case due to lack of other similar cases in familial history. To date, 33 patients with anterior cervical hypertrichosis have been reported. Anterior cervical hypertrichosis can be associated with other abnormalities, but it frequently presents as an isolated defect (70%). The association of vesicoureteral reflux and anterior cervical hypertrichosis which was observed in our patient might be coincidental. So far, no case of anterior cervical hypertrichosis associated with vesicoureteral reflux has been reported in the literature. PMID:27103865

    Cervical ripening is a complex process of modification of cervical tissue that enables dilation of the cervix at parturition. Cervical smooth muscle tissue might play a role by contracting or by secretion of cytokines or MMPs. To assess a contractile role for the cervical smooth muscle cells in cervical dilatation, we measured cervical diameter with ultrasound cervimetry together with EMG-activity of the myometrium, cervical outer muscular layer (COML) and cervical stromal layer (CSL).

    2012-01-01

    Cervical spondylosis is a broad term which describes the age related chronic disc degeneration, which can also affect the cervical vertebrae, the facet and other joints and their associated soft tissue supports. Evidence of spondylitic change is frequently found in many asymptomatic adults. Radiculopathy is a result of intervertebral foramina narrowing. Narrowing of the spinal canal can result in spinal cord compression, ultimately resulting in cervical spondylosis myelopathy. This review article examines the current literature in relation to the cervical spondylosis and describes the three clinical syndromes of axial neck pain, cervical radiculopathy and cervical myelopathy.

    Background A considerable number of patients with cervical spondylosis complain about one or multiple atypical symptoms such as vertigo, palpitations, headache, blurred vision, hypomnesia, and/or nausea. It remains unclear whether surgical intervention for cervical spondylosis can also effectively alleviate those symptoms. The current study was performed to see if anterior cervical diskectomy and fusion (ACDF) offers such an extra benefit for patients with cervical spondylosis. Objective To investigate if patients who received ACDF for the treatment of cervical spondylotic myelopathy and/or radiculopathy can also achieve alleviation of certain atypical symptoms associated with cervical spondylosis after the surgery in the long run. Methods Sixty-seven patients who underwent ACDF for the treatment of cervical spondylotic myelopathy and/or radiculopathy were involved in this study. All these patients also complained about various associated atypical symptoms. They were followed up for 26 to 145 months after the surgery. Severity and frequency scores of the atypical symptoms before the surgery and at last follow-up were compared by paired t tests. Results Most patients reported significantly alleviated symptoms at the last follow-up compared with before the surgery. The severity of vertigo, headache, nausea, and palpitations were significantly alleviated at the last follow-up (with p values of p cervical spondylotic myelopathy and/or radiculopathy, but it is not effective in alleviating symptoms such as tinnitus, blurred vision, and hypomnesia. It can be considered for alleviating atypical symptoms when other treatment options prove ineffective. PMID:27168319

    Erdmann, Christine A.; Apte, Michael G.

    2003-09-01

    Using the US EPA 100 office-building BASE Study dataset, they conducted multivariate logistic regression analyses to quantify the relationship between indoor CO{sub 2} concentrations (dCO{sub 2}) and mucous membrane (MM) and lower respiratory system (LResp) building related symptoms, adjusting for age, sex, smoking status, presence of carpet in workspace, thermal exposure, relative humidity, and a marker for entrained automobile exhaust. In addition, they tested the hypothesis that certain environmentally-mediated health conditions (e.g., allergies and asthma) confer increased susceptibility to building related symptoms within office buildings. Adjusted odds ratios (ORs) for statistically significant, dose-dependent associations (p < 0.05) for dry eyes, sore throat, nose/sinus congestion, and wheeze symptoms with 100 ppm increases in dCO{sub 2} ranged from 1.1 to 1.2. These results suggest that increases in the ventilation rates per person among typical office buildings will, on average, reduce the prevalence of several building related symptoms by up to 70%, even when these buildings meet the existing ASHRAE ventilation standards for office buildings. Building occupants with certain environmentally-mediated health conditions are more likely to experience building related symptoms than those without these conditions (statistically significant ORs ranged from 2 to 11).

  19. Comparison of MR and fluoroscopic mucous fistulography in the pre-operative evaluation of infants with anorectal malformation: a pilot study

    International Nuclear Information System (INIS)

    Anorectal malformations are often associated with rectal pouch fistulas. Surgical correction requires accurate evaluation of the presence and position of such fistulas. Fluoroscopy is currently the chosen modality for the detection of fistulas. The role of MRI is unexplored. To compare the diagnostic accuracy of MR versus fluoroscopic fistulography in the pre-operative evaluation of infants with anorectal malformation. We conducted a pilot study of infants requiring defunctioning colostomy for initial management of anorectal malformation. Dynamic sagittal steady-state free-precession MRI of the pelvis was acquired during introduction of saline into the mucous fistulas. Findings were compared among MR fistulography, fluoroscopic fistulography and intraoperative inspection. Eight children were included. Median age at fistulography was 15 weeks, inter-quartile range 13-20 weeks; all were boys. There was full agreement among MR fistulography, fluoroscopic fistulography and surgical findings. The pilot data suggest that MR fistulography is promising in the pre-operative evaluation of children with anorectal malformation. (orig.)

    Full Text Available Worldwide, cervical cancer is the third most common cancer in women, and the first or second most common in developing countries. Cervical cancer remains in Colombia the first cause of cancer mortality and the second cause of cancer incidence among women, despite the existence of screening programs during the last 3 decades. Bucaramanga, Manizales and Cali reported rates around 20 per 100,000 and Pasto 27 per 100,000. The Cali cancer registry has reported a progressive decrease in the age standardized incidence and mortality rates of cervical cancer over the past 40 years. Reasons for the decline in incidence and mortality of cervical cancer are multiple and probably include: improvement in socio-economic conditions, decrease in parity rates and some effect of screening programs.Human papilloma Virus is the main cause of cervical cancer, HPV natural history studies have now revealed that HPVs are the commonest of the sexually transmitted infec¬tions in most populations. Most HPV exposures result in sponta¬neous clearance without clinical manifestations and only a small fraction of the infected persons, known as chronic or persistent carriers, will retain the virus and progress to precancerous and cancer. HPV 16 and 18 account for 70% of cervical cancer and the 8 most common types. (HPV 16, 18, 45, 33, 31, 52, 58 and 35 account for about 90% of cervical cancer. Case-control studies also allowed the identification of the following cofactors that acting together with HPV increase the risk of progression from HPV persistent infection to cervical cancer: tobacco, high parity, long term use of oral contraceptives and past infections with herpes simplex type 2 and Chlamydia trachomatis. The demonstration that infection with certain types of human papillomavirus (HPV is not only the main cause but also a necessary cause of cervical cancer has led to great advances in the prevention of this disease on two fronts: (i Primary prevention by the use of

    We wished to evaluate the incidence of non-contiguous spinal injury in the cervicothoracic junction (CTJ) or the upper thoracic spines on cervical spinal MR images in the patients with cervical spinal injuries. Seventy-five cervical spine MR imagings for acute cervical spinal injury were retrospectively reviewed (58 men and 17 women, mean age: 35.3, range: 18-81 years). They were divided into three groups based on the mechanism of injury; axial compression, hyperflexion or hyperextension injury, according to the findings on the MR and CT images. On cervical spine MR images, we evaluated the presence of non-contiguous spinal injury in the CTJ or upper thoracic spine with regard to the presence of marrow contusion or fracture, ligament injury, traumatic disc herniation and spinal cord injury. Twenty-one cases (28%) showed CTJ or upper thoracic spinal injuries (C7-T5) on cervical spinal MR images that were separated from the cervical spinal injuries. Seven of 21 cases revealed overt fractures in the CTJs or upper thoracic spines. Ligament injury in these regions was found in three cases. Traumatic disc herniation and spinal cord injury in these regions were shown in one and two cases, respectively. The incidence of the non-contiguous spinal injuries in CTJ or upper thoracic spines was higher in the axial compression injury group (35.5%) than in the hyperflexion injury group (26.9%) or the hyperextension (25%) injury group. However, there was no statistical significance ({rho} > 0.05). Cervical spinal MR revealed non-contiguous CTJ or upper thoracic spinal injuries in 28% of the patients with cervical spinal injury. The mechanism of cervical spinal injury did not significantly affect the incidence of the non-contiguous CTJ or upper thoracic spinal injury.

    2015-06-01

    Full Text Available Prostate cancer (PC represents the second most frequent type of tumor in men worldwide. Proteomics represents a promising approach for the discovery of new biomarkers able to improve the management of PC patients. Markers more specific and sensitive than prostate-specific antigen are needed for PC diagnosis, prognosis and response to treatment. Moreover, proteomics could represent an important tool to identify new molecular targets for PC tailored therapy. Now several possible PC biomarkers sources, each with advantages and limitations, are under investigation, including tissues, urine, serum, plasma and prostatic fluids. Innovative high-throughput proteomic platforms are now identifying and quantifying new specific and sensitive biomarkers for PC detection, stratification and treatment. Nevertheless, many putative biomarkers are still far from being applied in clinical practice.This review aims to discuss the recent advances in PC proteomics, emphasizing biomarker discovery and their application to clinical utility for diagnosis and patient stratification.

    Aluminum (Al) toxicity is a major constraint for plant root development and growth as well as crop yield in acidic soils, which constitute approximately 40% of the potentially arable lands worldwide. The mechanisms of Al tolerance in plants are not well understood. As a whole systems approach, proteomic techniques have proven to be crucial as a complementary strategy to explore the mechanism in Al toxicity. Review here focuses on the potential of proteomics to unravel the common and plant species-specific changes at proteome level under Al stress, via comparative analysis of the Al-responsive proteins uncovered by recent proteomic studies using 2DE. Understanding the mechanisms of Al tolerance in plants is critical to generate Al resistance crops for developing sustainable agriculture practices, thereby contributing to food security worldwide.

    Analysis of cerebrospinal fluid (CSF) offers key insight into the status of the central nervous system. Characterization of murine CSF proteomes can provide a valuable resource for studying central nervous system injury and disease in animal models. However, the small volume of CSF in mice has thus far limited individual mouse proteome characterization. Through non-terminal CSF extractions in C57Bl/6 mice and high-resolution liquid chromatography-mass spectrometry analysis of individual murine samples, we report the most comprehensive proteome characterization of individual murine CSF to date. Utilizing stringent protein inclusion criteria that required the identification of at least two unique peptides (1% false discovery rate at the peptide level) we identified a total of 566 unique proteins, including 128 proteins from three individual CSF samples that have been previously identified in brain tissue. Our methods and analysis provide a mechanism for individual murine CSF proteome analysis.

  15. Letter: Contraceptive choice and cervical cytology.

    Science.gov (United States)

    Leppaluoto, P

    1974-02-15

    In the evaluation of biological potentials of contraceptives in the genesis of cervical cancer, cytology seems to have been given due attention while information on the clinical condition and specific treatment of the target organ, the cervix, is repeatedly neglected. "Cancer does not develop in a healthy cervix" is an old dogma derived from impressions gained by clinical examination of the organ. This concept is supported by epidemiologic studies indicating that cancer is extremely rare in cervices restored to a normal condition by cauterization. It may be postulated that this type of treatment destroys the permissive target cells of the cervix, thus indirectly rendering possible coitus-associated and contraceptive-associated(?) mutagen(s) invalid. Also, in comparative studies, an evaluation should be made of the significance of a higher incidence of cervical ectopy reported in women receiving oral hormonal contraceptives. The importance of ectopy in the genesis of cervical malignancy has been derived from the presumption that permissive cervical cells are thus created and exposed to vaginal contents which may harbor the mutagens(s). Therefore, it would seem not only desirable but imperative to include the neglected parameters of clinical condition and of specific treatment (both past and present) of the uterine cervix in the structure of studies like the recent one in this Journal on "Contraceptive choice and cervical cytology", by Drs. Shulman and Merritt. Still another parameter which might prove to be of significance is the predominant type of vaginal flora, which can be assessed readily in the routine examination of Papanicolaou smears. It may be that vaginal contents, which would seem to be somewhat different in wearers of the intrauterine contraceptive device as compared to "pill" users, might play a part in the advent of cervical malignancy as a medium of or for coitus-associated mutagens(s).

Although surgery and chemoradiotherapy can cure 80%–95% of women with early stage cancer, the recurrent and metastatic disease remains a major cause of cancer death. Many efforts have been made to design new drugs and develop gene therapies to treat cervical cancer. In recent decades, research on treatment strategies has proposed several options, including the role of HPV E6 and E7 oncogenes, which are retained and expressed in most cervical cancers and whose respective oncoproteins are critical to the induction and maintenance of the malignant phenotype. Other efforts have been focused on antitumor immunotherapy strategies. It is known that during the development of cervical cancer, a cascade of abnormal events is induced, including disruption of cellular cycle control, perturbation of antitumor immune response, alteration of gene expression, and deregulation of microRNA expression. Thus, in this review article we discuss potential targets for the treatment of cervical cancer associated with HPV infection, with special attention to immunotherapy approaches, clinical trials, siRNA molecules, and their implications as gene therapy strategies against cervical cancer development.Keywords: Cervical cancer, clinical trials, gene therapy, HPV E6 and E7 oncogenes, siRNAs

  1. Proteomics methods applied to malaria: Plasmodium falciparum

    International Nuclear Information System (INIS)

    Malaria is a parasitic disease that has a high impact on public health in developing countries. The sequencing of the plasmodium falciparum genome and the development of proteomics have enabled a breakthrough in understanding the biology of the parasite. Proteomics have allowed to characterize qualitatively and quantitatively the parasite s expression of proteins and has provided information on protein expression under conditions of stress induced by antimalarial. Given the complexity of their life cycle, this takes place in the vertebrate host and mosquito vector. It has proven difficult to characterize the protein expression during each stage throughout the infection process in order to determine the proteome that mediates several metabolic, physiological and energetic processes. Two dimensional electrophoresis, liquid chromatography and mass spectrometry have been useful to assess the effects of antimalarial on parasite protein expression and to characterize the proteomic profile of different p. falciparum stages and organelles. The purpose of this review is to present state of the art tools and advances in proteomics applied to the study of malaria, and to present different experimental strategies used to study the parasite's proteome in order to show the advantages and disadvantages of each one.

    2016-09-25

    Fungal pathogens are causal agents of numerous human, animal, and plant diseases. They employ various infection modes to overcome host defense systems. Infection mechanisms of different fungi have been subjected to many comprehensive studies. These investigations have been facilitated by the development of various '-omics' techniques, and proteomics has one of the leading roles in this regard. Fungal conidia and sclerotia could be considered the most important structures for pathogenesis as their germination is one of the first steps towards a host infection. They represent interesting objects for proteomic studies because of the presence of unique proteins with unexplored biotechnological potential required for pathogen viability, development and the subsequent host infection. Proteomic peculiarities of survival structures of different fungi, including those of biotechnological significance (e.g., Asperillus fumigatus, A. nidulans, Metarhizium anisopliae), in a dormant state, as well as changes in the protein production during early stages of fungal development are the subjects of the present review. We focused on biological aspects of proteomic studies of fungal survival structures rather than on an evaluation of proteomic approaches. For that reason, proteins that have been identified in this context are discussed from the point of view of their involvement in different biological processes and possible functions assigned to them. This is the first review paper summarizing recent advances in proteomics of fungal survival structures. PMID:26777984

    dasHPPboard is a novel proteomics-based dashboard that collects and reports the experiments produced by the Spanish Human Proteome Project consortium (SpHPP) and aims to help HPP to map the entire human proteome. We have followed the strategy of analog genomics projects like the Encyclopedia of DNA Elements (ENCODE), which provides a vast amount of data on human cell lines experiments. The dashboard includes results of shotgun and selected reaction monitoring proteomics experiments, post-translational modifications information, as well as proteogenomics studies. We have also processed the transcriptomics data from the ENCODE and Human Body Map (HBM) projects for the identification of specific gene expression patterns in different cell lines and tissues, taking special interest in those genes having little proteomic evidence available (missing proteins). Peptide databases have been built using single nucleotide variants and novel junctions derived from RNA-Seq data that can be used in search engines for sample-specific protein identifications on the same cell lines or tissues. The dasHPPboard has been designed as a tool that can be used to share and visualize a combination of proteomic and transcriptomic data, providing at the same time easy access to resources for proteogenomics analyses. The dasHPPboard can be freely accessed at: http://sphppdashboard.cnb.csic.es. PMID:26144527

    The proteins expressed by a genome have been termed the proteome. By comparing the proteome of a disease-affected tissue with the proteome of an unaffected tissue it is possible to identify proteins that play a role in a disease process. The hippocampus is involved in the processing of short-term memory and is affected in Alzheimer's disease. Any comparative proteome analysis that can identify proteins important in a disease affecting the hippocampus requires the characterization of the normal hippocampal proteome. Therefore, we homogenised normal hippocampal tissue and separated the proteins by two-dimensional polyacrylamide gel electrophoresis (2DE). Seventy-two unique protein spots were collected from Coomassie blue-stained 2DE gels and subjected to in-gel digestion with trypsin, reversed-phase high-pressure liquid chromatography peptide separation, and N-terminal protein sequencing. Sufficient protein sequence was obtained to successfully characterize 66 of the 72 protein spots chosen (92%). Three of the 66 proteins were not present in any database (4.5%). The characterized proteins comprised two dominant functional groups, i.e., enzymes involved in intermediary cellular metabolism (40%), and proteins associated with the cytoskeleton (15%). The identity, molecular mass, isoelectric point, and relative concentration of the characterized proteins are described and constitute a partial proteome map of the normal human hippocampus.

    The case of a one-month-old patient admitted to the Department of Pediatrics (Medical and Health Science Center, Debrecen University) because of respiratory distress caused by a cervical mass compressing the upper respiratory pathways is presented. The mass could only be partially removed, the histological diagnosis proved to be neuroblastoma (SBCT: "small blue cell tumor"). Despite the fact that the DNA index of tumor cells (ploidy measurements) and the age of the patient suggested a favourable prognosis, the tumor continued to grow and metastases appeared. Because of symptoms of compression exerted on the respiratory system by the tumor, chemotherapy had to be applied. Since a standard OPEC/OJEC chemotherapeutic protocol proved to be not entirely effective and a residual tumor was still present, retinoic acid and interferon treatment was introduced. Presently, 4 years after the diagnosis, the patient is in complete remission and can be considered to be cured. The case presented here demonstrates that despite the favorable prognosis of the majority of infant neuroblastomas, in some cases the anatomic location of the tumor, leading to disturbance of vital functions, may serve as indication of chemotherapy. Our experience also proved the efficacy of retinoic acid and interferon treatment in relapsed neuroblastoma. PMID:15105902

    Several different physics procedures have been tried to mechanize the recording of partograms. Can a measure of impedance of tissue Z using potential difference V, according to Ohm's law V = Z1, and 1 is a constant, be correlated with a measure of cervical dilatation using vaginal examination? This was our hypothesis. The tissue impedance meter was made to our design and applied according to a bipolar procedure. Our work was carried out on 28 patients. 10 patients were registered before labour started in order to test the apparatus and to record the impedance variations without labour taking place, and 18 patients were registered in labour to see whether there was any correlation. The level of impedance in the cervix without labour was 302.7 Ohms with a deviation of 8.2. Using student's t tests it was found that there was a significant correlation (p less than 0.001) in four measurements between the impedance measure and measures obtained by extrapolating the degrees of dilatation calculated from vaginal examination. This is a preliminary study in which we have defined the conditions that are necessary to confirm these first results and to further develop the method. PMID:1401774

    Directory of Open Access Journals (Sweden)

    Li Zhang

    Full Text Available Comparative proteomics of the multiple strains within the same species can reveal the genetic variation and relationships among strains without the need to assess the genomic data. Similar to comparative genomics, core proteome and pan proteome can also be obtained within multiple strains under the same culture conditions. In this study we present the core proteome and pan proteome of four epidemic Salmonella Paratyphi A strains cultured under laboratory culture conditions. The proteomic information was obtained using a Two-dimensional gel electrophoresis (2-DE technique. The expression profiles of these strains were conservative, similar to the monomorphic genome of S. Paratyphi A. Few strain-specific proteins were found in these strains. Interestingly, non-core proteins were found in similar categories as core proteins. However, significant fluctuations in the abundance of some core proteins were also observed, suggesting that there is elaborate regulation of core proteins in the different strains even when they are cultured in the same environment. Therefore, core proteome and pan proteome analysis of the multiple strains can demonstrate the core pathways of metabolism of the species under specific culture conditions, and further the specific responses and adaptations of the strains to the growth environment.

  3. Invasive cervical carcinoma (Stages IB-IIB)

    International Nuclear Information System (INIS)

    In the patients with invasive cervical carcinoma, the accurate assessment of parametrial invasion greatly affects the therapeutic choice between surgery and radiation therapy. As a matter of fact, surgery is usually performed only in the patients with carcinoma confined to the cervix, whereas those with parametrial involvement, or more advanced stages, are treated with radiation therapy. This prospective study was aimed at investigating the comparative adequecy of CT and MR imaging in assessing parametrial status in the patients with invasive cervical cancer. Twenty-one consecutive patients, with histologic diagnosis of cervical carcinoma, were investigated. All of them were clinically considered as having invasive cervical cancer (FIGO stage IB-IIB) and subsequently underwent surgery. In all cases, detailed histology of the parametrium was obtained. Pathological data were compared with CT and MR findings in all cases. As for assessing parametrial involvement by cancer, CT had 62% accuracy, 63% sensitivity, and 60% specificity, versus MR imaging 81% accuracy, 69% sensitivity, and 80% specificify. Therefore, MR imaging appears to be superior to CT in assessing the parametrial status of patients with invasive cervical carcinoma; the method yields valuable information for treatment planning

    Full Text Available Objective. We aim to investigate methods and use of cervical ripening in women without and with a prior cesarean delivery in The Netherlands. Methods. In 2010, we conducted a postal survey in all Dutch hospitals with a labor ward. One gynecologist per hospital was addressed and was asked to respond on behalf of the staff. The questionnaire contained 31 questions concerning cervical ripening and induction of labor. We compared this survey to a similar Dutch survey conducted in 2006. Results. Response rate was 78% (70/92 hospitals. In women without a prior cesarean and in need of cervical ripening, all hospitals (100% applied prostaglandins (either E1 or E2. In women with a prior cesarean, 21.4% of the hospitals performed an elective cesarean section if delivery was indicated (26.0% in 2006. In case of cervical ripening, 72.7% used mechanical methods (49.1% in 2006, 20.0% used prostaglandins (40.4% in 2006, 3.6% used a combination of prostaglandins and mechanical methods, and 3.6% used membrane-sweeping or oxytocin. Conclusions. In 2010, in The Netherlands, prostaglandins and Foley catheters were the preferred methods for cervical ripening in women without and with a prior cesarean, respectively. Use of mechanical methods in women with a prior cesarean has increased rapidly between 2006 and 2010, corresponding with decreasing use of prostaglandins and elective repeat cesarean sections.

    The objective of this prospective case-control study was to determine whether uterine corpus and cervical length measurements have a role in dysmenorrhoea aetiology in virgins. Patients with severe primary dysmenorrhoea with visual analog scale scores of ≥7 composed the dysmenorrhoea group (n = 51), while the control group (n = 51) was of women with painless menstrual cycles or with mild pain. Longitudinal and transverse axes of the uterine cervix and uterine corpus were measured. Correlation between severity of dysmenorrhoea and uterine cervix and corpus axes was calculated. Longitudinal and transverse axes of uterine cervix as well as uterine cervix volume were significantly higher in the dysmenorrhoea group compared to the controls. There was a significant positive correlation between severity of dysmenorrhoea and the length of cervical longitudinal and transverse axes and uterine cervical volume. Our findings reveal longer cervical length and greater cervical volume in young virgin patients with dysmenorrhoea and severe pain compared to those with no or less pain. PMID:27012227

  14. Source of error in the chromatographic study of 35S-sulfate labeled mucous glycoproteins secreted by the gill epithelium of Mytilus edulis

    International Nuclear Information System (INIS)

    HPLC combined with [35S]-sulfate/[3H]-glucosamine radiolabeling were employed to study the synthesis and secretion of mucous glycoproteins. The secreted radiolabeled glycoproteins were separated from the medium by precipitation with a mixture of trichloroacetic-phosphotungstic acids (TCA/PTA). The redissolved glycoproteins were chromatographed on an anion exchange protein column at varying pH of the mobile phase and fractions were collected for liquid scintillation counting. Varying the pH of the mobile phase from pH 3 to 7 resulted in a decrease of glycoprotein bound [35S] from 69.5 to 0.5% of the total recovered [35S]-sulfate with the remainder recovered as free [35S]-sulfate. The [3H]-labeled glycoprotein recovered under the uV peaks at this pH range was 99.5%. When high performance size exclusion chromatography was performed the change in mobile phase pH did not affect the 100% recovery of either [35S]-or [3H]-labels under the uV peaks. No free [35S]-sulfate was obtained when [35S]-labeled glycoproteins were separated from the medium using dialysis. These data suggest that the standard method of TCA/PTA precipitation of [35S]-labeled glycoproteins may cleave the [35S]-sulfate ester linkages to the oligosaccharide chains. The [35S]-sulfate may then rebind to the macromolecule by a relatively strong noncovalent bond. This may prove critical in anion exchange protein HPLC studies

    Epidural steroid injections (ESI) are a common treatment for back pain management. ESI-related complications have increased with the growing number of procedures. We report a case of cervical meningomyelitis followed by multiple lumbar ESI. A 60-year-old male with diabetes mellitus presented to our hospital with severe neck pain. He had a history of multiple lumbar injections from a local pain clinic. After admission, high fever and elevated inflammatory values were detected. L-spine magnetic resonance imaging (MRI) revealed hematoma in the S1 epidural space. Antibiotic treatment began under the diagnosis of a lumbar epidural abscess. Despite the treatment, he started to complain of weakness in both lower extremities. Three days later, the weakness progressed to both upper extremities. C-spine MRI revealed cervical leptomeningeal enhancement in the medulla oblongata and cervical spinal cord. Removal of the epidural abscess was performed, but there was no neurological improvement.

    Advances in proteomic technologies have made import contribution to the development of personalized medicine by facilitating detection of protein biomarkers, proteomics-based molecular diagnostics, as well as protein biochips and pharmacoproteomics. Application of nanobiotechnology in proteomics, nanoproteomics, has further enhanced applications in personalized medicine. Proteomics-based molecular diagnostics will have an important role in the diagnosis of certain conditions and understanding the pathomechanism of disease. Proteomics will be a good bridge between diagnostics and therapeutics; the integration of these will be important for advancing personalized medicine. Use of proteomic biomarkers and combination of pharmacoproteomics with pharmacogenomics will enable stratification of clinical trials and improve monitoring of patients for development of personalized therapies. Proteomics is an important component of several interacting technologies used for development of personalized medicine, which is depicted graphically. Finally, cancer is a good example of applications of proteomic technologies for personalized management of cancer. PMID:26827601

    A 48-year-old man presented to the emergency department with complain of severe neck pain and anterior chest pain. Intermittent fever in the recent 2 days was also noted. There is a track maker over his left side of neck. The laboratory examination showed leukocytosis and high C-reactive protein level. Urine drug screen was positive for opiate. Empirical antibiotic administration was given. Blood culture grew gram-positive cocci in chain, and there was no vegetation found by heart echocardiogram. However, progressive weakness of four limbs was noted, and patient even cannot stand up and walk. The patient also complained of numbness sensation over bilateral hands and legs, and lower abdomen. Acute urine retention occurred. We arranged magnetic resonance imaging survey, which showed evidence of inflammatory process involving the retropharyngeal spaces and epidural spaces from the skull base to the bony level of T5. Epidural inflammatory process resulted in compression of the spinal cord and bilateral neural foramen narrowing. Neurosurgeon was consulted. Operation with laminectomy and posterior fusion with bone graft and internal fixation was done. Culture of epidural abscess and 2 sets of blood culture all yielded methicillin-sensitive Staphylococcus aureus. For epidural abscess, the most common involved spine is lumbar followed by thoracic and cervical spine. Diagnosis and treatment in the drug abusers are still challenging because they lack typical presentation, drug compliance, and adequate follow-up and because it is hard to stop drug abuser habit. Significant improvement of neurological deficit can be expected in most spinal abscess in drug abusers after treatment. PMID:26298050

    Both tuberculosis cervical lymphadenitis (TCL) and oropharyngeal tularaemia (OT) have similar signs, symptoms and pathological findings. We aimed to investigate the frequency of tularaemia antibodies in patients diagnosed with TCL. Using data from the Tuberculosis Control Dispensaries between the years of 2008 and 2011 in Turkey, all patients diagnosed with TCL were informed about and included in the study. Control group subjects were selected from healthy blood donors who lived in the same region. After informed consent was obtained, the sera obtained from volunteer TCL patients and the control group were tested with a microagglutination technique for Francisella tularensis. Antibodies to Brucella were also investigated with a tube agglutination test for cross-reactivity in sera that were seropositive for tularaemia. Sera were obtained from a total of 1170 individuals in the TCL group and 596 in the control group from 67 of 81 provinces in Turkey. Francisella tularensis-positive antibodies were found in 79 (6.75%) cases in the TCL group and two (0.33%) cases in the control group with a titre of ≥1:80 (p < 0.01). When the presence of antibody of any titre was considered, the ratio became 8.2% (96/1170) in the TCL group and 0.67% (4/596) in the control group (p < 0.001). For the first time, with this study, tularaemia serology was found to be positive in a significant portion (6.75%) of diagnosed cases of TCL. In tularaemia endemic regions, it was concluded that tularaemia serology should be investigated in patients suspected of having TCL. PMID:23211027

Schwannomas are extramedullary-intradural tumors composed of Schwann cells, which can arise from spinal nerves at any level (cervical, thoracic, lumbar, or cauda equina and most often arise from a posterior (sensory nerve root. The most common initial symptom therefore is pain in a radicular distribution. Early detection and surgery gives excellent results in such cases.

    Nine patients with serious cervical spine injuries that occurred while they were playing rugby were seen in a British Columbia acute spinal cord injury unit during the period 1975-82. All the injuries had occurred during the "scrum" or the "tackle". Two of the patients were rendered permanently quadriplegic, and one patient died. There is a need for a central registry that would record all cervical spine injuries in rugby players as well as for changes in the rules of the game. PMID:6697282

  17. CT discography for cervical soft disc hernia

    International Nuclear Information System (INIS)

    In this study the effectiveness of computed tomographic discography (CTD) in diagnosing cervical soft disc hernia was evaluated. Twenty-five interververtebral discs of 15 cases with cervical soft disc hernia were examined with a discography and then a CT scan. Results of the CT scan were as follows: three discs were protruded, 12 discs were prolapsed, 6 discs were extruded, and 4 discs were sequestrated. The findings were helpful in determining the location of soft disc hernians between the median and posterolateral discs. They were also valuable in classifying types of hernians and surgical aproaches. (author)

  1. Cervical spine injury in child abuse: report of two cases

    International Nuclear Information System (INIS)

    Pediatric cervical spine injuries have rarely been reported in the setting of child abuse. We report two cases of unsuspected lower cervical spine fracture-dislocation in twin infant girls who had no physical examination findings to suggest cervical spine injury. Classic radio-graphic findings of child abuse were noted at multiple other sites in the axial and appendicular skeleton. Magnetic resonance (MR) imaging proved to be valuable in both the initial evaluation of the extent of cervical spine injury and in following postoperative changes. The unexpected yet devastating findings in these two cases further substantiate the importance of routine evaluation of the cervical spine in cases of suspected child abuse. (orig.)

    Phytohormones are orchestrators of plant growth and development. A lot of time and effort has been invested in attempting to comprehend their complex signaling pathways but despite success in elucidating some key components, molecular mechanisms in the transduction pathways are far from being resolved. The last decade has seen a boom in the analysis of phytohormone-responsive proteins. Abscisic acid, auxin, brassinosteroids, cytokinin, ethylene, gibberellins, nitric oxide, oxylipins, strigolactones, salicylic acid - all have been analyzed to various degrees. For this review, we collected data from proteome-wide analyses resulting in a list of over 2000 annotated proteins from Arabidopsis proteomics and nearly 500 manually filtered protein families merged from all the data available from different species. We present the currently accepted model of phytohormone signaling, highlight the contributions made by proteomic-based research and describe the key nodes in phytohormone signaling networks, as revealed by proteome analysis. These include ubiquitination and proteasome mediated degradation, calcium ion signaling, redox homeostasis, and phosphoproteome dynamics. Finally, we discuss potential pitfalls and future perspectives in the field.

    In the last decades, the continuous and rapid evolution of proteomic approaches has provided an efficient platform for the characterization of food-derived proteins. Particularly, the impressive increasing in performance and versatility of the MS instrumentation has contributed to the development of new analytical strategies for proteins, evidencing how MS arguably represents an indispensable tool in food proteomics. Investigation of protein composition in foodstuffs is helpful for understanding the relationship between the protein content and the nutritional and technological properties of foods, the production of methods for food traceability, the assessment of food quality and safety, including the detection of allergens and microbial contaminants in foods, or even the characterization of genetically modified products. Given the high variety of the food-derived proteins and considering their differences in chemical and physical properties, a single proteomic strategy for all purposes does not exist. Rather, proteomic approaches need to be adapted to each analytical problem, and development of new strategies is necessary in order to obtain always the best results. In this tutorial, the most relevant aspects of MS-based methodologies in food proteomics will be examined, and their advantages and drawbacks will be discussed. PMID:25230173

    Uranium is used in many chemical forms in civilian and military industries and is a known nephro-toxicant. A key issue in monitoring occupational exposure is to be able to evaluate the potential damage to the body, particularly the kidney. In this study we used innovative proteomic techniques to analyse urinary protein modulation associated with acute uranium exposure in rats. Given that the rat urinary proteome has rarely been studied, we first identified 102 different proteins in normal urine, expanding the current proteome data set for this central animal in toxicology. Rats were exposed intravenously to uranyl nitrate at 2.5 and 5 mg/kg and samples were collected 24 h later. Using two complementary proteomic methods, a classic 2-DE approach and semi-quantitative SDS-PAGE-LC-MS/MS, 14 modulated proteins (7 with increased levels and 7 with decreased levels) were identified in urine after uranium exposure. Modulation of three of them was confirmed by western blot. Some of the modulated proteins corresponded to proteins already described in case of nephrotoxicity, and indicated a loss of glomerular permeability (albumin, alpha-1-anti-proteinase, sero-transferrin). Others revealed tubular damage, such as EGF and vitamin D-binding protein. A third category included proteins never described in urine as being associated with metal stress, such as ceruloplasmin. Urinary proteomics is thus a valuable tool to profile uranium toxicity non-invasively and could be very useful in follow-up in case of accidental exposure to uranium. (authors)

    The aim of this study was to determine the frequency of abnormal cervical cytology in preoperative cervical cytology of patients diagnosed with uterine papillary serous carcinoma (UPSC) and endometrioid endometrial carcinoma (EEC). In addition, associations between abnormal cervical cytology and clinicopathologic factors were evaluated. In this multicentre study, EEC patients diagnosed at two hospitals from 1999 to 2009 and UPSC patients diagnosed at five hospitals from 1992 to 2009, were included. Revision of the histologic slides was performed systematically and independently by 3 gynecopathologists. Cervical cytology within six months before histopathologic diagnosis of endometrial carcinoma was available for 267 EEC and 80 UPSC patients. Cervical cytology with atypical, malignant, or normal endometrial cells in postmenopausal women was considered as abnormal cytology, specific for endometrial pathology. Abnormal cervical cytology was found in 87.5% of UPSC patients, compared with 37.8% in EEC patients. In UPSC, abnormal cytology was associated with extrauterine spread of disease (P=0.043). In EEC, abnormal cytology was associated with cervical involvement (P=0.034). In both EEC and UPSC patients, abnormal cervical cytology was not associated with survival. In conclusion, abnormal cervical cytology was more frequently found in UPSC patients. It was associated with extrauterine disease in UPSC patients, and with cervical involvement in EEC patients. More prospective research should be performed to assess the true clinical value of preoperative cervical cytology in endometrial cancer patients. PMID:23722512

    Compared to other data-intensive disciplines such as genomics, public deposition and storage of MS-based proteomics, data are still less developed due to, among other reasons, the inherent complexity of the data and the variety of data types and experimental workflows. In order to address this need, several public repositories for MS proteomics experiments have been developed, each with different purposes in mind. The most established resources are the Global Proteome Machine Database (GPMDB), PeptideAtlas, and the PRIDE database. Additionally, there are other useful (in many cases recently developed) resources such as ProteomicsDB, Mass Spectrometry Interactive Virtual Environment (MassIVE), Chorus, MaxQB, PeptideAtlas SRM Experiment Library (PASSEL), Model Organism Protein Expression Database (MOPED), and the Human Proteinpedia. In addition, the ProteomeXchange consortium has been recently developed to enable better integration of public repositories and the coordinated sharing of proteomics information, maximizing its benefit to the scientific community. Here, we will review each of the major proteomics resources independently and some tools that enable the integration, mining and reuse of the data. We will also discuss some of the major challenges and current pitfalls in the integration and sharing of the data. PMID:25158685

    Full Text Available Abstract: The goal of disease-related proteogenomic research is a complete description of the unfolding of the disease process from its origin to its cure. With a properly selected patient cohort and correctly collected, processed, analyzed data, large scale proteomic spectra may be able to provide much of the information necessary for achieving this goal. Protein spectra, which are one way of representing protein expression, can be extremely useful clinically since they can be generated from blood rather than from diseased tissue. At the same time, the analysis of circulating proteins in blood presents unique challenges because of their heterogeneity, blood contains a large number of different abundance proteins generated by tissues throughout the body. Another challenge is that protein spectra are massively parallel information. One can choose to perform top-down analysis, where the entire spectra is examined and candidate peaks are selected for further assessment. Or one can choose a bottom-up analysis, where, via hypothesis testing, individual proteins are identified in the spectra and related to the disease process. Each approach has advantages and disadvantages that must be understood if protein spectral data are to be properly analyzed. With either approach, several levels of information must be integrated into a predictive model. This model will allow us to detect disease and it will allow us to discover therapeutic interventions that reduce the risk of disease in at-risk individuals and effectively treat newly diagnosed disease.

    Hair root cells actively divide in a hair follicle, and they sensitively reflect physical conditions. By analyzing the human hair, we can know stress levels on the human body and metabolic conditions caused by microgravity environment and cosmic radiation. The Japan Aerospace Exploration Agency (JAXA) has initiated a human research study to investigate the effects of long-term space flight on gene expression and mineral metabolism by analyzing hair samples of astronauts who stayed in the International Space Station (ISS) for 6 months. During long-term flights, the physiological effects on astronauts include muscle atrophy and bone calcium loss. Furthermore, radiation and psychological effects are important issue to consider. Therefore, an understanding of the effects of the space environment is important for developing countermeasures against the effects experienced by astronauts. In this experiment, we identify functionally important target proteins that integrate transcriptome, mineral metabolism and proteome profiles from human hair. To compare the protein expression data with the gene expression data from hair roots, we developed the protein processing method. We extracted the protein from five strands of hair using ISOGEN reagents. Then, these extracted proteins were analyzed by LC-MS/MS. These collected profiles will give us useful physiological information to examine the effect of space flight.

    INTRODUCTION: A reason for not recommending subtotal hysterectomy is the risk of cervical pathology. We aimed to evaluate cervical cancer screening and to describe cervical pathology after subtotal and total hysterectomy for benign indications. METHODS: Data regarding adherence to screening.......7% were not screened. We found a minimum of one abnormal test in 28 (10.8%) after subtotal hysterectomy and one after total hysterectomy. No cervical cancers were found. CONCLUSIONS: Adherence to cervical cancer screening after subtotal hysterectomy in a Danish population is suboptimal and some patients...... have unnecessary tests performed after total hysterectomy. Clarification of the use of cervical/vaginal smears after hysterectomy is needed to identify women at risk of cervical dysplasia or cancer.

    Full Text Available Abstract Background We estimated the number of women undergoing cervical cancer screening annually in Italy, the rates of cervical abnormalities detected, and the costs of screening and management of abnormalities. Methods The annual number of screened women was estimated from National Health Interview data. Data from the Italian Group for Cervical Cancer Screening were used to estimate the number of positive, negative and unsatisfactory Pap smears. The incidence of CIN (cervical intra-epithelial neoplasia was estimated from the Emilia Romagna Cancer Registry. Patterns of follow-up and treatment costs were estimated using a typical disease management approach based on national guidelines and data from the Italian Group for Cervical Cancer Screening. Treatment unit costs were obtained from Italian National Health Service and Hospital Information System of the Lazio Region. Results An estimated 6.4 million women aged 25–69 years undergo screening annually in Italy (1.2 million and 5.2 million through organized and opportunistic screening programs, respectively. Approximately 2.4% of tests have positive findings. There are approximately 21,000 cases of CIN1 and 7,000–17,000 cases of CIN2/3. Estimated costs to the healthcare service amount to €158.5 million for screening and €22.9 million for the management of cervical abnormalities. Conclusion Although some cervical abnormalities might have been underestimated, the total annual cost of cervical cancer prevention in Italy is approximately €181.5 million, of which 87% is attributable to screening.

    Cervical cancer (CC) is caused by high-risk human papillomavirus persistence due to the immunosuppressive tumor microenvironment mediated by cytokines. Vaginal microbiota determines the presence of certain cytokines locally. We assessed the association between cervical microbiota diversity and the histopathological diagnosis of each stage of CC, and we evaluated mRNA cervical expression levels of IL-4, IL-6, IL-10, TGF-β1, TNF-α and IFN-γ across the histopathological diagnosis and specific bacterial clusters. We determined the cervical microbiota by high throughput sequencing of 16S rDNA amplicons and classified it in community state types (CST). Mean difference analyses between alpha-diversity and histopathological diagnosis were carried out, as well as a β-diversity analysis within the histological diagnosis. Cervical cytokine mRNA expression was analyzed across the CSTs and the histopathological diagnoses. We found a significant difference in microbiota's diversity in NCL-HPV negative women vs those with squamous intraepithelial lesions (SIL) and CC(p = 0.006, p = 0.036).When β-diversity was evaluated, the CC samples showed the highest variation within groups (p<0.0006) and the largest distance compared to NCL-HPV negative ones (p<0.00001). The predominant bacteria in women with normal cytology were L. crispatus and L. iners, whereas for SIL, it was Sneathia spp. and for CC, Fusobacterium spp. We found higher median cervical levels of IL-4 and TGF-β1 mRNA in the CST dominated by Fusobacterium spp. These results suggest that the cervical microbiota may be implicated in cervical cancer pathology. Further cohort studies are needed to validate these findings. PMID:27115350

    A discogenic cervical headache is a subtype of cervicogenic headache (CEH) that arises from a degenerative cervical disc abnormality. The purpose of this study was to evaluate the clinical outcome of percutaneous endoscopic cervical discectomy (PECD) for patients with chronic cervical headache due to soft cervical disc herniation. Seventeen patients underwent PECD for intractable headache. The inclusion criteria were soft disc herniation without segmental instability, proven by both local anesthesia and provocative discography for headache unresponsive to conservative treatment. The mean follow-up period was 37.6 months. Fifteen of the 17 patients (88.2%) showed successful outcomes based on the Macnab criteria. Pain scores on a visual analog scale (VAS) improved from a preoperative mean of 8.35{+-}0.79 to 2.12{+-}1.17, postoperatively (P<0.01). The mean disc height decreased from 6.81{+-}1.08 to 5.98{+-}1.07 mm (P<0.01). There was no newly developed segmental instability or spontaneous fusion on follow-up radiography. In conclusion, PECD appears to be effective for chronic severe discogenic cervical headache under strict inclusion criteria. (orig.)

    Full Text Available Background: Although preventable, cervical cancer, an AIDS-related disease, is the second most common cancer amongst South African women and the most common cancer amongst black women. Objective: The objective of the study was to determine what women being treated for HIV and AIDS at a specific healthcare centre in Johannesburg knew about cervical cancer and cervical screening. Method: A survey design was used, with data gathered by means of a self-administered questionnaire. Convenience sampling selected 315 women to participate (n = 315. Descriptive statistics were used to analyse the data and chi-square testing found associations between categorical variables. Results: The majority of respondents (78.7%; n = 248 indicated that they had heard of cervical cancer and 62.9% (n = 198 knew about the Pap smear, with nurses and doctors being the primary source of information. Of the women who knew about the Pap smear, less than one-third had had a smear done, the main reason being fear of the procedure. Conclusion: The study provided evidence that women attending the specific HIV clinic were more knowledgeable about cervical cancer and screening than those of unknown HIV status involved in previous studies. Knowledge was still at a low level, especially when their exceptionally high risk was taken into account. Once again it was found that having knowledge did not necessarily mean having had a Pap smear, which remains a huge challenge in the prevention of cervical cancer.
