The procedures denominated fast-Fourier-transform spectral method (FFTSM), complex-demodulation method (CDM), modified-moving-average method (MMAM), Laplacian-likelihood-ratio method (LLRM), and adaptive-match-filter

method (AMFM) were applied to interferences-corrupted synthetic ECG tracings and Holter ECG recordings from control-healthy subjects (CH-group; n=25) and acute-myocardial-infarction patients (AMI group; n=25). The presence of interferences in simulated data caused detection of false-positive TWA by all techniques but the FFTSM and AMFM. Clinical applications evidenced a discrepancy in that the FFTSM and LLRM detected no more than one TWA case in each population, whereas the CDM, ARRY-142886 MMAM, and AMFM detected TWA in all CH-subjects and AMI-patients, with significantly lower TWA amplitude in the former group. Because the AMFM is not prone to false-positive TWA detections, the latter finding suggests TWA as a phenomenon having continuously changing amplitude from physiological to pathological conditions. Only occasional detection of TWA by the FFTSM and LLRM in clinics can be ascribed to their limited ability in identifying TWA in the presence of interferences surviving preprocessing. (C) 2010 IPEM.

“We report results of NMR experiments

on the ruthenium oxide Hg2Ru2O7 with the pyrochlore structure, which exhibits a metal-insulator transition at T-MI = 107 K. In the metallic phase above TMI, the nuclear spin-lattice relaxation rate 1/T-1 and the Knight shift at the Hg sites follow the Korringa relation, indicating the absence

of selleck compound substantial spatial spin correlation. At low temperatures in the insulating phase, Ru-99,Ru-101-NMR signals are observed at zero magnetic field, providing evidence for a commensurate antiferromagnetic order. The estimated ordered moment is about 1 mu(B) per Ru, much smaller than 3 mu(B) expected for the ionic (4d)(3) configuration of Ru5+. Thus, the localized spin models are not appropriate for the insulating phase of Hg2Ru2O7. We also discuss possible antiferromagnetic spin structures.”
“Assessment of the early stages of fracture healing via X-rays and computed tomography is limited by the low radio-opacity of cartilage. We validated a method of contrast-enhanced computed tomography (CECT) click here for non-destructive identification of cartilage within a healing fracture callus. Closed, stabilized fractures in femora of C57BL/6 mice were harvested on post-operative day 9.5 and imaged ex vivo with micro-computed tomography (mu CT) before and after incubation in a cationic contrast agent that preferentially accumulates in cartilage due to the high concentration of sulfated glycosaminoglycans in the tissue. Co-registration of the pre- and post-incubation images, followed by image subtraction, enabled two- and three-dimensional delineation of mineralized tissue, soft callus, and cartilage.

Univariate and Ferroptosis assay multivariate logistic regression analyses were used to evaluate the influence of a wide range of variables on postoperative complications.\n\nResults: Seventy-two patients had one or more early wound complications (49.7%). These complications comprised haematoma (n = 3, 2.1%), wound infection (n = 30, 20.7%), wound necrosis (n = 25, 17.5%) and seroma (n = 31, 21.8%). Wound infections were infections were significantly more common in patients with a body mass index (BMI) of > 25 (p = 0.019).

Wound necrosis developed significantly more often if the Bohler Braun splint was not used postoperatively (p = 0.002). The occurrence of one or more ealy complications was significantly associated with non-use of a Bohler Braun splint (p = 0.026) and age of > 55 years (p = 0.015).\n\nConclusions: High BMI was significantly correlated with the occurrence of wound infections. Bed with of the hip and knee in flexion using a Bohler splint improved wound ARN-509 inhibitor healing

after therapeutic ilio-inguinal lymph node dissection. (C) 2008 Elsevier Ltd. All rights reserved.”
“The evaluation of meat spoilage is based on sensory and microbiological analyses. The disadvantages of sensory analyses are its reliance on highly trained panelists, a procedure which makes it costly and unattractive for routine analyses. Moreover, the classical microbiological analyses are lengthy, costly and destructive. In this study a portable fluorescence spectrometer was tested to quantify minced beef spoilage. This study was investigated on samples stored aerobically and under vacuum at 5 and 15 degrees C. Total viable counts (TVC), Pseudomonas, lactic acid bacteria, and yeast/molds counts were investigated with classical culture methods. Fluorescence spectra were recorded on the same samples using different excitation LEDs (280, 320, and 380 nm). PLS-R with leave-one-out cross validation was used to perform calibration and validation models. The PLS-R models presented good R-CV(2) (0.50-0.99) and ratio of standard deviation (RPDCV: 1.40-8.95) values after cross-validation. It could be concluded that portable spectrofluorimeters

are promising devices to evaluate spoilage in minced beef. (C) 2011 Elsevier Ltd. All rights SC79 in vivo reserved.”
“For the past few years, a large number of diesel vehicles carrying gravel and sand have shuttled back and forth every day on the main route (Tai-16 and Tai-21 highways) from Shuili to Shinyi in Nantou County, Taiwan, in support of a river-dredging project. Five stations along Tai-16 and three stations along Tai-21 were selected as the exposure sites. Two very small villages located about 9 and 12 kilometers, respectively, away from the diesel transport routes were selected as the control sites. In this study, five exposure pathways, i.e., ingestion from drinking water, household dust, rice, non-rice dishes, and inhalation from airborne particles, were considered.

After administration of the contrast medium, the mass was prominently enhanced. It extended upward through the left inguinal ring into the left lower abdomen.\n\nPreoperative diagnosis of continuous-type SGF by contrast-enhanced spiral CT is possible depending on the basis of its characteristic CT features.”
“Protein tyrosine phosphatase 1B (PTP1B) is a prototype non receptor cytoplasmic PTPase enzyme that has been implicated

in regulation of insulin and leptin signaling pathways. Studies on PTP1B knockout mice and PTP1B antisense treated mice suggested that inhibition of PTP1B would be an effective strategy for the treatment of type II diabetes and obesity. Here we report the X-ray structure of PTP1B in complex with compound IN1834-146C (PDB ID 4I8N). The crystals belong to P3(1)21 space CA4P group with cell dimensions (a = b = 87.89 angstrom, c = 103.68 angstrom)

diffracted to 2.5 angstrom. The crystal structure contained one molecule of protein in the asymmetric unit and was solved by molecular replacement GSK-J4 method. The compound engages both catalytic site and allosteric sites of PTP1B protein. We described the molecular interaction of the compound with the active site residues of PTP1B in this crystal structure report.”
“Xanthomonas oryzae pv. oryzae (Xoo) is the casual agent of bacterial blight, which is one of the most serious diseases of rice. The antibiotic phenazine-1-carboxylic acid (PCA), which is primarily produced by Pseudomonas spp., was found and previously reported very effective against Xoo. However, the biological effects of PCA Ganetespib solubility dmso on Xoo remain

unclear. In this study, we found that PCA increased the accumulation of reactive oxygen species (ROS) and reduced the activities of catalase (CAT) and superoxide dismutase (SOD) in Xoo. Xoo was more sensitive to H2O2 than Xanthomonas oryzae pv. oryzicola (Xoc), and had a much lower expression of CAT genes. In addition, proteomic analysis indicated that PCA inhibited carbohydrate metabolism and nutrient uptake in Xoo, and analysis of carbon source utilization further confirmed that carbohydrate metabolism in Xoo was repressed by PCA. In conclusion, PCA acted as a redox-cycling agent that disturbed the redox balance in Xoo and reduced CAT and SOD activities, resulting in higher accumulation of ROS, altered carbohydrate metabolism, and lower energy production and nutrient uptake. Moreover, a deficient antioxidant system in Xoo made it very sensitive to PCA. (C) 2014 Elsevier Inc. All rights reserved.”
“The physical factors of cell-culture environment have received little attention despite their anticipated significant role in human embryonic stem cell (hESC) culture optimization. Here we show that hESC culture conditions can be optimized by utilizing polyethylene terephthalate (PET) membranes whose defined pore densities (PDs) determine membrane surface hardness. The PET membranes with 1-4 x 10(6) pores/cm(2) (0.291-0.

Immunohistochemistry was performed on the tissue microarray using monoclonal antibodies which we have developed to the retinoic acid metabolising enzymes CYP26A1, CYP26B1, CYP26C1 and lecithin retinol acyl transferase (LRAT) using a semi-quantitative scoring scheme to assess expression. Moderate or strong expression of CYP26A1 was observed in 32.5% of cancers compared to 10% of normal colonic epithelium samples (p smaller than 0.001). CYP26B1 was moderately or strongly expressed in 25.2% of tumours and was significantly less expressed in normal colonic epithelium (p smaller than 0.001). CYP26C1 was not expressed in any sample. LRAT also showed significantly increased expression

in primary colorectal cancers compared with normal colonic epithelium (p smaller than 0.001). Strong CYP26B1 expression was significantly associated with poor prognosis (HR =1.239, 95%CI =1.104-1.390, selleck chi(2) = 15.063, p =0.002). Strong Dinaciclib nmr LRAT was also associated with poorer outcome (HR= 1.321, 95%CI = 1.034-1.688, chi(2) = 5.039, p =0.025). In mismatch repair proficient tumours strong

CYP26B1 (HR 1.330, 95%CI =1.173-1.509, chi(2) 21.493, p smaller than 0.001) and strong LRAT (HR =1.464, 950/0CI=1.110-1.930, chi(2) = 7.425, p= 0.006) were also associated with poorer prognosis. This study has shown that the retinoic acid metabolising enzymes CYP26A1, CYP26B1 and LRAT are significantly overexpressed in colorectal cancer and that CYP26B1 and LRAT are significantly associated with prognosis both in the total cohort and in those tumours which are mismatch repair proficient. CYP26B1 was independently prognostic in a multivariate model both in the whole patient cohort (HR =1.177, 95%CI =1.020-1.216, p=0.026) and in mismatch repair proficient tumours (HR = 1.255, 950/0CI = 1.073 – 1.467, PI3K inhibitor p =0.004).”
“The peripheral nervous

system is critically involved in bone metabolism, osteogenesis, and bone remodeling. Nerve fibers of sympathetic and sensory origin innervate synovial tissue and subchondral bone of diathrodial joints. They modulate vascularization and matrix differentiation during endochondral ossification in embryonic limb development, indicating a distinct role in skeletal growth and limb regeneration processes. In pathophysiological situations, the innervation pattern of sympathetic and sensory nerve fibers is altered in adult joint tissues and bone. Various resident cell types of the musculoskeletal system express receptors for sensory and sympathetic neurotransmitters. Osteoblasts, osteoclasts, mesenchymal stem cells, synovial fibroblasts, and different types of chondrocytes produce distinct subtypes of adrenoceptors, receptors for vasointestinal peptide, for substance P and calcitonin gene-related peptide. Many of these cells even synthesize neuropeptides such as substance P and calcitonin gene-related peptide and are positive for tyrosine-hydroxylase, the rate-limiting enzyme for biosynthesis of catecholamines.

MRI was performed on a 4.7 T animal scanner, preradiation treatment, as well as at 3, 6, 9, and 14 days postradiation. Image features of the tumors, as well as tumor volumes and animal survival, were quantitatively compared. Structural MRI showed that all irradiated tumors still grew in size during the initial days postradiation. The apparent diffusion coefficient (ADC) values of tumors increased significantly postradiation (40 and 20 Gy), except at day 3 postradiation, compared with

preradiation. The tumor blood flow decreased significantly postradiation (40 and 20 Gy), but the relative blood flow (tumor vs contralateral) did not show a significant change at most time points postradiation. The amide proton transfer weighted (APTw) signals of the tumor decreased significantly at all time points postradiation

YAP-TEAD Inhibitor 1 ic50 (40 Gy), and also at day 9 postradiation (20 Gy). The blood flow and APTw maps demonstrated tumor features that were similar to those seen on gadolinium-enhanced RG-7112 datasheet T-1-weighted images. Tumor ADC, blood flow, and APTw were all useful imaging biomarkers by which to predict glioma response to radiotherapy. The APTw signal was most promising for early response assessment in this model.”
“For applications to harvest solar energy, it is essential to characterize upconverter materials under broadband excitation at reasonable irradiance levels AZD0530 Angiogenesis inhibitor achievable by concentration of solar radiation. We present a method to determine the absolute upconversion quantum yield (UCQY) under broad-band excitation by photoluminescence measurements. We introduce a spectral mismatch correction that allows calculating the UCQY that can be expected under illumination with the

solar spectrum with a certain solar concentration. Applying these methods to beta-NaYF4 doped with 25%Er3+, we determine an external UCQY of 2.0% in the spectral range from 1450 nm to 1600 nm under a comparatively low solar concentration of only 50 suns. This value corresponds to a potential increase of the short-circuit current density of 3.89 mA/cm(2). Subsequently, we measure the external quantum efficiency due to upconversion of sub-band-gap photons for a bifacial silicon solar cell with upconverter attached to its rear side under the same broad-band excitation. We determine an additional short-circuit current density due to upconversion of 4.03 mA/cm(2) for a solar concentration of only 77 suns. This value agrees very well, with the expected additional short-circuit current density due to upconversion, calculated from the external UCQY values as determined by the photoluminescence measurements, by considering the transmittance of the solar cell for sub-band-gap photons and the external quantum efficiency of the solar cell for photons emitted by the upconverter.

Suckling during 12 to 14 h postpartum is insufficient to maintain lactation and the process of involution that occurs in early lactation is reversible within 1 day of farrowing but is irreversible if a gland is not used for 3 days. However, milk yield from a gland which

is ‘rescued’ within Endocrinology & Hormones inhibitor the first 24 h remains lower throughout lactation. Suckling does not only affect milk yield in the ongoing lactation, but it also seems to affect that of the next lactation. Indeed, non-suckling of a mammary gland in first-parity sows decreased development and milk yield of that gland in second parity. Nursing behaviour of piglets in early lactation was also affected, where changes were indicative of piglets in second parity being hungrier when suckling glands that were not previously used. It is not known, however, if the same effects would be seen between the second and third lactation. Furthermore, the minimum suckling period required to ensure maximal milk yield from a gland in the next lactation is not known. This review provides an update on our current knowledge of the importance of suckling for mammary development and milk yield in swine.”
“Postoperative paraplegia IAP inhibitor secondary to spinal cord ischemia (SCI) is an extremely rare and devastating complication of endovascular repair in abdominal aortic aneurysm (AAA) surgery. The reported incidence is only 0.21 % worldwide. This case of postoperative paraplegia occurred in

a 60-year-old man immediately following endovascular repair of an infrarenal AAA. Postoperative magnetic resonance imaging showed multiple foci of SCI involvement from C5 to L1. However, neither cerebral spinal fluid drainage nor steroid therapy was effective; he was eventually admitted with no improvement in his neurological status. The mechanism remains multifactorial until now and needs more attention in perioperative management. We report the first case involved in the most

significantly extensive SCI after endovascular repair of an infrarenal AAA.”
“We performed a descriptive retrospective study of cases of listeriosis occurring in Spain from 2001 VX-770 clinical trial to 2007 to determine the burden and trend of this disease in our setting. Several sources of information were used. Epidemiological information was collected from 1.242 cases of listeriosis, representing a mean incidence rate of 0,56 cases per 100.000 inhabitants per year, which was extrapolated as an overall estimate for Spain. The annual incidence showed a statistically significant increasing trend (p smaller than 0,001) over the study period. This figure was higher than that reported in Spain (0,16) by the Microbiological Information System, which is voluntary, showing that underreporting exists. The inclusion of listeriosis in the Mandatory Notification System would allow determination of the distribution and characteristics of this infection in humans, as well as promotion of effective prevention and control.

In contrast, overexpressed MnSOD exhibited an insignificant effect on long-term engraftment of transplanted HSCs, but had a significant beneficial effect after an insult of sublethal irradiation. Taken together, these results demonstrate that HSC function can be enhanced by ectopic expression of ROS-detoxifying enzymes, especially after radiation exposure in vivo.”
“Although multicystic dysplastic kidney (MDK) is a common renal anomaly, the management of this condition remains controversial. The purpose

AS1842856 supplier of this study was to focus on its regression by ultrasound (US) scan for MDK managed conservatively.\n\nBetween 1990 and 2010, 50 children with MDK were retrospectively studied. All patients were submitted to radioisotope scan to confirm the diagnosis, and a micturating cystogram to exclude other uropathies.\n\nOf the 50 patients, 19 underwent nephrectomy,

and the other 31 were conservatively managed with clinical and US scan follow-up. Neuronal Signaling inhibitor The mean follow-up time (range 6 months to 11 years) in the non-operated group was 6.2 years. Of the 31 children with nonsurgical management, 17 (54.8%) showed total involution on US scan, 7 (22.6%) showed a partial regression, and 7 (22.6%) were unchanged at the time of this study. The mean time to complete disappearance on US scan was 2.5 years (1-4 years). No children developed hypertension or tumors.\n\nThe natural history of MDK is usually benign, but patients must have long-term follow-up with US scan. In addition, many studies confirmed that

the disappearance of it on a US scan does Bafilomycin A1 not mean a total involution of the affected kidney. We recommend a strict follow-up even when US scan shows an undetectable kidney.”
“A simplified conceptual model based on timescales of gravitational circulation, vertical exchange, and total oxygen consumption rate of the biochemical processes is presented to provide insight into the relationships between estuarine dynamics and bottom water dissolved oxygen (DO). Two dimensionless parameters are introduced to diagnose the relationship between the vertical exchange process and the biochemical DO consumption and the influence of gravitational circulation on replenishment of bottom DO. The relative magnitudes of these timescales provide a linkage between the physical and biochemical processes. The hypoxic and anoxic conditions in deep waters of Chesapeake Bay are successfully interpreted with these three proposed timescales. Because the Bay is a long estuary, the replenishment of the bottom DO due to gravitational circulation diminishes as the bottom water travels farther upstream. The bottom DO is mainly modulated by the vertical exchange process in the middle and upper portions of the Bay.

The result of reverse transcription PCR analysis demonstrated that the expressions of ITG beta 1 and BMP-2 were significantly (p < 0.05) upregulated on the LRF coating in a time-dependent manner, compared with uncoated Ti. These findings suggested that the LRF technology might be a promising potential treatment for fabricating CaP coatings on titanium implants.”
“Aim. In Trans-Atlantic Inter-Society Concensus (TASC) patients at risk for critical limb

ischemia (CLI) without symptoms are termed “chronic subclinical ische mia,” but research are still lacking. The objective was to find out whether clinically asymptomatic contralateral limbs at the time of treatment for ipsilateral CLI could be regarded as “chronic subclinical ischemia”.\n\nMethods. Ninety-six patients with CLI who had no symptoms in the contralateral limb were retrospectively reviewed. The symptoms of the contralateral Blasticidin S mw limb

after initial intervention for the ipsilateral limb were surveyed. Risk factors for developing CLI and tissue loss were then analyzed.\n\nResults. Five patients (5.2%) became claudicants, 37 patients (38.5%) had symptoms of CLI, and 14 (14.6%) experienced tissue loss during the follow-up period. The overall CLI-free rates at 12, 36, and 60 months were 79.2%, 55.2%, and 45.8%, Selleckchem Dinaciclib respectively, while the tissue loss-free rates at 12, 36, and 60 months were 91.3%, 78.8%, and 78.8%, respectively. Risk factor for developing CLI on the contralateral limb was having skin perfusion pressure

(SPP) <40 mmHg at the surgery for ipsilateral limb. The presence of SPP <40 mmHg and end stage renal failure with hemodialysis resulted in a significantly high probability of tissue loss.\n\nConclusion. Patients with CLI with an asymptomatic contralateral limb with an SPP value <40 mmHg are at a high risk of developing CLI and tissue loss during the follow-up period. Information on the contralateral limb at initial surgery may help to speculate the fate of the asymptomatic contralateral limb.”
“Depletion of crude oil resources and environmental concerns have driven a worldwide research on alternative processes for the production of commodity chemicals. Fischer-Tropsch synthesis is a process for flexible production of key chemicals from synthesis gas originating from non-petroleum-based PS-095760 sources. Although the use of iron-based catalysts would be preferred over the widely used cobalt, manufacturing methods that prevent their fast deactivation because of sintering, carbon deposition and phase changes have proven challenging. Here we present a strategy to produce highly dispersed iron carbides embedded in a matrix of porous carbon. Very high iron loadings ( bigger than 40 wt %) are achieved while maintaining an optimal dispersion of the active iron carbide phase when a metal organic framework is used as catalyst precursor.

Furthermore, two-step surgical management was successfully performed consisting of i) tumor-reductive selleck chemicals llc excision and ii) limb salvage surgery, including wide resection of the tumor mass, defect reconstruction of the chest wall using left latissimus dorsi myocutaneous flap and dermatoplasty of the flap-supplied region. The progress of the clinical characteristics, the reasons for radiation-induced carcinogenesis, the treatment options and the prognostic factors of MFH are also reviewed. Finally, the importance of prevention and follow-up of this malignancy are highlighted and specific advice is offered.”
“Salivary gland transfer (SGT) has the potential to prevent radiation-induced xerostomia. We attempt

to analyze the efficacy of SGT in prevention of xerostomia and maintenance of salivary flow rates after radiation treatment (XRT). Systematic review and meta-analysis. Primary endpoint was efficacy of SGT in prevention of radiation-induced xerostomia. Secondary endpoint was change from baseline of unstimulated and stimulated salivary flow rates after XRT.

Seven articles, accruing data from 12 institutions, A-1155463 solubility dmso met inclusion criteria. In a total of 177 patients at mean follow-up of 22.7 months, SGT prevented radiation-induced xerostomia in 82.7% (95% CI, 76.6-87.7%) of patients. Twelve months after XRT, unstimulated and stimulated salivary flow rates rose to 88% and 76% of baseline values, respectively. In comparison to control subjects twelve months after XRT, SGT subjects’ unstimulated (75% vs. 11%) and stimulated (86% vs. 8%) salivary flow rates were drastically higher in SGT patients. Salivary

selleck gland transfer appears to be highly effective in preventing the incidence of xerostomia in patients receiving definitive head and neck radiation therapy. (C) 2013 Elsevier Ltd. All rights reserved.”
“Interleukin (IL)-23 plays a predominant role in the development of autoimmune diseases by inducing IL-17-producing helper T (Th17) cells. The receptor for IL-23 consists of a heterodimer composed of the IL-12 receptor beta 1 (IL-12R beta l) and the IL-23 receptor (IL-23R), which is mainly expressed on Th17 cells. A recent study showed that macrophages express IL-23R mRNA and can be distinguished from microglia by IL-23R expression. However, in this study, we show by RT-PCR and immunocytochemistry that microglia express IL-23R and IL-12R beta 1 mRNA and protein, respectively. Additionally, microglia expressed a functional receptor for IL-23, as IL-23 enhanced the Interferon (IFN)-gamma-induced signal transducer and activator of transcription (STAT)l phosphorylation and chemokine production. Thus, IL-23R expression does not discriminate peripheral macrophages from microglia. Moreover, since microglia produce IL-23, it may function in an autocrine manner to recruit inflammatory cells by inducing chemokine production.

A unique thermoplastic behavior was evidenced. Heat-treated PRFs acquire high modulus but show low temperatures of thermal flow which can be systematically manipulated through the thermal pretreatment. Loss of volatiles, changes in molecular weight, and glass transition temperature (T-g) were investigated using thermogravimetric analysis (TGA), mass spectrometry (MS), and differential

scanning calorimetry (DSC), respectively. Underlying mechanisms for the thermal and rheological behavior are discussed with regard to interactions between pyrolytic lignin nanopartides present in the system www.selleckchem.com/products/gsk923295.html and the role of volatile materials on determining the properties of the material resembling in several aspects to colloidal suspension systems. Low thermal JQ1 chemical structure flow temperatures and reversible thermal effects can be attributed to association of pyrolytic lignin particles due to intermolecular interactions that are easily ruptured at higher temperatures. The thermoplastic behavior of PRF and its low T-g is of particular interest, as it gives opportunities for application of this fraction in several melt processing and adhesive technologies.”
“In mammals, the female reproductive tract (FRT) develops from a pair of paramesonephric or Mullerian

ducts (MDs), which arise from coelomic epithelial cells of mesodermal origin. During development, the MDs undergo a dynamic morphogenetic transformation from simple tubes consisting of homogeneous epithelium and surrounding mesenchyme into several distinct organs namely the oviduct, uterus, cervix and vagina. Following the formation of anatomically

distinctive organs, the uniform MD epithelium (MDE) differentiates into diverse epithelial cell types with unique morphology and functions in each organ. Classic tissue recombination studies, in which the epithelium and mesenchyme isolated from the newborn mouse FRT were recombined, have established that the organ specific epithelial cell fate of MDE is dictated by the underlying mesenchyme. The tissue recombination studies have also demonstrated that there is a narrow developmental window for the epithelial cell fate determination in MD-derived organs. Accordingly, the developmental plasticity of epithelial cells is mostly lost Elafibranor order in mature FRT. If the signaling that controls epithelial differentiation is disrupted at the critical developmental stage, the cell fate of MD-derived epithelial tissues will be permanently altered and can result in epithelial lesions in adult life. A disruption of signaling that maintains epithelial cell fate can also cause epithelial lesions in the FRT. In this review, the pathogenesis of cervical/vaginal adenoses and uterine squamous metaplasia is discussed as examples of such incidences. (C) 2011 Published by Elsevier Ltd.
