An appropriate implantation site favors angiogenesis and avoids ovarian tissue damage after tissue grafting. The objective of this study was to evaluate the effects of intramuscular (IM) and subcutaneous (SC) sites for ovarian grafts in goats by evaluating follicular morphology and activation, preantral follicle and stromal cell densities, tissue DNA fragmentation, collagen types I and III depositions, and graft revascularizations. Ovarian cortical tissue was transplanted in IM or SC sites and recovered 7 or 15 days post-transplantation. There was a greater percentage of developing follicles and lesser follicular and stromal cell densities in all grafted tissues as compared to ovarian tissues of the control group. The stromal cell density and percentage of normal follicles were positively associated. At 15 days post-transplantation, tissues at the SC and IM sites had similar amounts of DNA fragmentation and type III collagen content. In contrast, tissues at the SC, as compared with IM site, had greater abundances of collagen type I. Furthermore, there was a positive association between collagen type I and percentage of morphologically normal follicles post-transplantation. In addition to a marked decrease in follicular density 15 days post-transplantation in ovarian grafts at the SC and IM sites, low percentages of normal follicles and follicular activation were observed similarly in both transplantation sites. There were also positive associations of stromal cell density and abundance of type I collagen fibers with the percentage of intact follicles in grafted ovarian tissues.

The control of abiotic parameters is fundamental for fish survival, growth and reproduction. These factors have a direct effect on sperm quality. Thus, this study evaluated the effect of different temperatures (29, 31, 33, and 35°C), pHs (4 and 8), and hypoxia (1 mgO2 L−1) on sperm motility of Colossoma macropomum (tambaqui). The results indicated a longer duration of sperm motility at 29°C (50.1 ± 2.70 s) that progressively decreased when exposed to 35°C (31.2 ± 1.31 s) and hypoxia at pH 4 (27.4 ± 1.42 s) and pH 8 (30.44 ± 1.66 s; p < 0.05), respectively. Sperm oxygen consumption increased in hypoxia at both pH (pH 4 = 61.22; pH 8 = 54.74 pmol s−1). There was an increase in the activity of glutathione-S-transferase (GST) and superoxide dismutase (SOD), as well as in lipid peroxidation levels (LPO) and DNA damage in sperm exposed to higher temperatures and hypoxia. The pH 4 and pH 8 under normoxia did not affect the quality of C. macropomum sperm. These results suggest that water warming and acidification, consequences of climate changes, significantly affect the reproduction of C. macropomum, reducing the quality of spermatozoids during fertilization.

- Abstract
A 34-year- old man was referred to the outpatient clinic because of progressive abdominal pain, weight loss and pancytopenia. His body mass index (BMI) had fallen to 14.2 kg/m2. A CT angiography (CTA) showed narrowing of the truncus coeliacus with poststenotic dilation, and duodenal biopsy revealed ischaemia establishing a rare diagnosis: median arcuate ligament syndrome (MALS). This explained the postprandial pain and minimal intake. Further pancytopenia workup was performed. The bone marrow displayed gelatinous marrow transformation (GMT), a rare disorder of unknown pathogenesis, which has been associated with severe malnutrition. The final diagnosis was pancytopenia secondary to GMT due to severe malnutrition caused by MALS. The abnormalities in the bone marrow may be reversible by restoring nutritional status. This case emphasises the awareness of GMT in patients with weight loss, malnutrition and cytopenias. To our knowledge, this is the first report demonstrating an association between pancytopenia and MALS. [ABSTRACT FROM AUTHOR]

Currently, neoliberalism serves as the foundation for the majority of educational reform efforts. Neoliberal approaches repeatedly privilege the value of ‘expert’ knowledge in framing policy and practice, resulting in limited opportunities for the impact of local community knowledge and experience on teaching and learning. While the neoliberal context narrows what counts as learning, participatory action research (PAR), youth-led participatory action research (YPAR), and engaged scholarship emphasize collaborative problem-solving among community organizations and schools that can expose the dangers of neoliberal trends in education. The articles in this special edition, titled ‘Challenging Neoliberal Reforms through Collaborative, Community Engaged Research,’ illuminate diverse approaches to collaborative research aimed at fostering a more inclusive, productive dialog regarding the impact and possibilities for educational reforms in K-16 schools. The authors identify the specific neoliberal reform...

The aim of this study was to evaluate the effect of ovarian stimulation protocols on Doppler velocimetry parameters of the ovarian artery and its relationship with the follicular population and oocyte quality. Caninde goats (n = 10) were used for ovarian stimulation according to two different protocols: multiple doses (FSH) or a single dose (eCG). The follicular population and ovarian blood flow were determined in the ovarian arteries immediately after treatment through Doppler ultrasonography. To observe the oocyte quality, LOPU was used to aspirate the oocyte from the Graafian follicles and graded. In addition, blood samples were collected for Estradiol concentration. The results showed that the mean number of follicles per animal was higher (P 0.05) between treatment groups. A positive correlation (P

Recent studies observed an association between increased serum uric acid (SUA) levels and renal damage in lupus. However, the predictive value of UA for the development of long-term renal dysfunction in lupus nephritis (LN) is still unknown. The aim of this study was to evaluate if SUA may be a predictor of long-term renal outcome in LN. Eighty biopsy-proven LN patients > 7 years of follow-up were selected. SUA levels were measured in sera stored at − 70 °C. All patients had serum stored from LN baseline, and 32 also had stored serum from 6 and 12 months after LN. Renal outcome was addressed after 7 years of follow-up to determine if SUA could be a predictor of long-term renal outcome. A good long-term renal outcome in 7 years was defined as a creatinine clearance (CrCl) ≥ 90.0 mL/min/1.73 m2, and poor if CrCl

school choice ,accountability ,student testing. ,Education - Abstract
Among the two most prominent school reform measures currently being implemented in The United States are school choice and test-based accountability. Until recently, the two policy initiatives remained relatively distinct from one another. With the passage of the No Child Left Behind Act of 2001 (NCLB), a mutualism between choice and accountability emerged whereby school choice complements test-based accountability. In the first portion of this study we present a conceptual overview of school choice and test-based accountability and explicate connections between the two that are explicit in reform implementations like NCLB or implicit within the market-based reform literature in which school choice and test-based accountability reside. In the second portion we scrutinize the connections, in particular, between school choice and test-based accountability using a large western school district with a popular choice system in place. Data from three sources are combined to explore the ways in which school choice and test-based accountability draw on each other: state assessment data of children in the district, school choice data for every participating student in the district choice program, and a parental survey of both participants and non-participants of choice asking their attitudes concerning the use of school report cards in the district. Results suggest that choice is of benefit academically to only the lowest achieving students, choice participation is not uniform across different ethnic groups in the district, and parents' primary motivations as reported on a survey for participation in choice are not due to test scores, though this is not consistent with choice preferences among parents in the district. As such, our results generally confirm the hypotheses of choice critics more so than advocates. Keywords: school choice; accountability; student testing.

We describe an unusual case of blue toe syndrome as the primary and solitary manifestation of systemic sclerosis. The possible cause was long-term occupational exposure in construction work. Blue toe syndrome is a small vessel disease, characterised by the sudden development of painful, blue discolouration in one or more toes. The most common aetiology is atheroembolic disease; however, it can also appear in several conditions ranging from hypercoagulability disorders to underlying systemic diseases such as vasculitis or autoimmune diseases. Here, we describe the case of a 57-year-old man who presented with blue toe syndrome without underlying atheroembolic disease. He was found to have positive anticentromere antibodies, which indicated that systemic sclerosis was the likely primary underlying cause. An extensive systemic evaluation and a thorough physical examination revealed no other symptoms associated with systemic sclerosis. He was prescribed nifedipin and rosuvastatin, and showed complete resolution of symptoms after 3 months.

Biopsy pick-up (BPU) has been considered a safe method to harvest ovarian fragments from live animals. However, no studies have been reported on the use of BPU to collect in vivo ovarian tissue in goats. The goals of this study were: (i) to test different biopsy needle sizes to collect ovarian tissue in situ using the BPU method (Experiment 1), and (ii) to study ovarian tissue features such as preantral follicle density, morphology, class distribution, and stromal cell density in ovarian fragments obtained in vivo through a laparoscopic BPU method (Experiment 2). In Experiment 1, goat ovaries (n = 20) were collected in a slaughterhouse and subjected to in situ BPU. Three needles (16, 18, and 20G) were tested. In Experiment 2, the most efficient biopsy needle from Experiment 1 was used to perform laparoscopic BPU in goats (n = 8). In Experiment 1, the recovery rate was greater (P 0.05; range 50-62%) with 16G and 18G needles than the 20G (17%) needle. The mean weight of ovarian fragments collected by the 16G needle was greater (P 0.05) than the 18G and the 20G needle. In Experiment 2, 62 biopsy attempts were performed and 52 ovarian fragments were collected (90% success rate). Overall, 2054 preantral follicles were recorded in 5882 histological sections analyzed. Mean preantral follicular density was 28.4 ± 1.3 follicles per cm

- Abstract
Background: The tumor protein p53 (TP53) gene may be inactivated through 17p13 deletion, somatic mutations, or both. In chronic lymphocytic leukemia (CLL) although 17p13 deletion is correlated with poor prognosis, the role of sole TP53 mutations remains controversial. Materials and Methods: We carried out a mutation analysis of TP53 gene in 72 patients with CLL. Results: Seventy-one (98.6%) patients carried the polymorphic site c.215C>G, p.Pro72Arg, but its presence was not correlated with overall survival (OS). Moreover, 19 (26.4%) patients carried a mutation of TP53. Among the eight detected mutations, to our knowledge, one (c.587G>A) has never been reported in the past. There was a correlation of the mutation burden with the stage of the disease (p=0.022), but not with OS. None of the detected mutations was individually correlated with OS. Conclusion. The clinical significance of TP53 mutations is still a matter of debate and larger studies and meta-analyses are required to reach an unequivocal conclusion.

Introduction: Osteonecrosis (ON) is a multifactorial disease that leads to hip destruction. Lately, much focus has been at femoral head preservation with nonsurgical methods. In this study we examined the polymorphisms of IL-1α, IL-1R, IL-1RA, IL-4Rα, IL-1β, IL-12,γIFN, TGF-β, TNF-a, IL-2, IL-4, IL-6 and IL-10 genes for evaluation of their contribution in ON.Material and methods: DNA was extracted from 112 ON patients and 438 healthy donors. Analysis of the polymorphisms was completed using the PCR-SSP method. Statistical analysis was performed using theχ2test to compare the genotype and allelic frequency distribution.Results: The CT and GA genotypes of the IL-1α(-889) and TNF-a (-238) genes were found higher in the patients (51.8% and 10.8%, respectively) compared to the healthy donors (39.7% and 2.1%, respectively). In TGF-βcodon 25, the G to C polymorphism in the homozygous state was found in 1.8% of the patients and the C allele frequency was 8.9%, whereas the G allele frequency was 91.1%. Also, at the IL-10 (-1082) gene the GG genotype was 16.2% in the controls whereas in the patients was 7.2%.Conclusions: Based on the above, we showed that certain genotypes of the IL-1α, TGF-β, IL-10 and TNF-a genes could be related in the pathogenesis of a complicated disease, such as osteonecrosis. The presence of one of the above mentioned polymorphisms or the simultaneous carriage of more than one may further increase the risk for osteonecrosis, especially in those at high risk, such as patients receiving corticosteroids.

Background Sexual problems are common amongst cardiac patients, and concerns may arise when resuming sexual activities after a cardiac event. Sexual counselling is therefore indispensible. Culture is an identified barrier to talking about sex, but research is lacking on whether and how culture influences nurses in providing sexual counselling. Design This cross-sectional descriptive study assessed four areas related to sexual counselling provided by cardiovascular nurses. We investigated the impact of culture on these areas by surveying cardiovascular nurses living in Denmark, Norway and two regions of Belgium - Flanders, Dutch-speaking region and Wallonia, French-speaking region. Methods Overall, 819 participants were recruited as they attended cardiovascular nursing congresses in Denmark, Norway and Belgium. Subjects completed the Undertaking Nursing Interventions Throughout Europe (UNITE) sexual counselling questionnaire, measuring practice, responsibility, confidence and perceived comfort of patients. Controlling for demographic, educational and professional covariates, we performed multiple linear regression analysis to determine the impact of culture on sexual counselling. Results All four subscale scores were independently associated with culture. Danish nurses counselled patients significantly more often, reported feeling more responsibility and confidence and estimated more comfort in patients than Norwegian, Flemish and Walloon nurses. Conclusions This study showed that culture matters with respect to sexual counselling for cardiac patients. Interventions should be developed improving sexual counselling of cardiac patients. Educational courses and training of healthcare professionals on sexual counselling should be more sensitive to sociocultural differences. Cross-cultural perspectives may bias attitudes of professionals as they deal with concerns of cardiac patients about resuming sexual activity.

musculoskeletal diseases - Abstract
Osteoporosis is a common disease with a strong genetic component. Several studies have reported the vitamin D receptor (VDR), collagen type I (COL1A1), and LDL receptor-related protein 5 (LRP5) genes as the most likely candidates. However, most of the studies have been carried out in postmenopausal women and older men and show inconsistent results. CASE PRESENTATION: We report a case of a 26-year old male who presented with severe back pain of acute onset, unrelated to any kind of trauma, and diffuse myalgia. Imaging of the lumbar and the thoracic spine revealed two Grade 3, according to Genant’s semiquantitative method, vertebral fractures in T10 and T11 and multiple Grade 1 and 2 fractures from T8 to L2. Measurement of bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA) (Lunar Prodigy) showed severe osteoporosis of the lumbar spine (Z-score=-3.0, BMD = 0.866 gr/cm2). A complete laboratory and biochemical work-up was performed to exclude secondary causes of osteoporosis. Total genomic DNA was extracted from peripheral blood and was used as a template for genotype analysis. The patient was heterozygous for the p.V667M mutation of the LRP5 gene and for the BsmI [g.63980 G→A, rs1544410] and Sp1 polymorphisms [g.6252 G→T, rs1800012] of the VDR and COL1A1 genes, respectively. Further genotype analysis excluded types of osteogenesis imperfecta associated with mutations in the COL1A1 and COL1A2 genes. CONCLUSION: We herein show that the co-existence of three polymorphic sites in the VDR, COL1A1, and LPR-5 genes in a young male adult caused severe osteoporosis with multiple fractures, suggesting a combined effect and/or interaction between these genes. © 2016, Hellenic Endocrine Society.

Objective— The mechanism of neovascularization during the proliferative phase of infantile hemangioma is poorly understood. It is known that circulating bone marrow-derived endothelial progenitor cells (EPCs) form new blood vessels in ischemic tissues using mediators regulated by the transcription factor, HIF-1α. Mobilization of EPCs is enhanced by VEGF-A, matrix metalloproteinase (MMP)-9, and estrogen, whereas homing is secondary to localized expression of stromal cell-derived factor-1α (SDF-1α). We examined whether these mediators of EPC trafficking are upregulated during the proliferation of infantile hemangioma. Methods and Results— Surgical specimens and blood samples were obtained from children with proliferating hemangioma and age-matched controls (n=10, each group). VEGF-A and MMP-9 levels were measured in blood, and tissue sections were analyzed for SDF-1α, MMP-9, VEGF-A, and HIF-1α. The role of estrogen as a modulator of hemangioma endothelial cell growth was also investigated. We found that all these mediators of EPC trafficking are elevated in blood and specimens from children with proliferating infantile hemangioma. In vitro, the combination of hypoxia and estrogen demonstrated a synergistic effect on hemangioma endothelial cell proliferation. Conclusions— These findings demonstrate that proliferating hemangiomas express known mediators of vasculogenesis and suggest that this process may play a role in the initiation or progression of this disease.

Hormonal ovarian stimulation may affect transcripts in somatic cells of cumulus-oocyte complexes (COCs) and affect the resulting oocyte quality. Here, in parallel with morphological classification and in vitro maturation (IVM) rate analysis, we investigated the expression of hyaluronan synthase 2 (HAS2), gonadotropic receptors (FSHR and LHR) and connexin 43 (GJA1) in cumulus cells (CCs) from goat COCs after multi-dose FSH (MD) or one-shot FSH/eCG (OS) treatments, using bovine COCs as control groups. The MD treatment produced more large follicles, and the resulting COCs had a better morphology and IVM rate than were obtained with OS. The OS treatment produced COCs with increased HAS2, FSHR, LHR and GJA1 expression. This gene expression pattern was also observed in the CCs of COCs that showed poor morphological characteristics. On the other hand, the mRNA levels were more similar between groups after IVM; FSHR and LHR were the main genes that showed decreased expression. Some events that occurred in bovine CCs during IVM, such as cell expansion, increased HAS2 expression and decreased GJA1 expression, were less evident or did not occur in goat COCs. In conclusion, increasing HAS2, FSHR, LHR and GJA1 expression in goat COCs does not confer greater meiotic competence to oocytes. Instead, it may result from poor regulation of gene expression in CCs by lower quality oocytes. Finally, cumulus expansion, together with HAS2 upregulation and GJA1 downregulation, seems to be more important for bovine COCs than for goat COCs. Additional studies are needed to investigate the importance of other HAS isoforms and connexins in goat COCs. Fil: Santos, Juliana D. R..

- Abstract
GA733-1/-2/-3 genes have been detected in various types of cancer, although their role has not been fully clarified. GA733-2 and GA733-1 have been correlated with lymph node metastases in laryngeal cancer and liver metastases, respectively. Only a few studies have elucidated the mechanisms regulating GA733-1/-2 expression and their effect on colorectal cancer. Therefore, the expression pattern and the role of the aforementioned molecules in colorectal carcinogenesis were evaluated in this study. Tissue samples were obtained from 40 patients with colorectal cancer with no liver metastases. GA733-1/-2 mRNA levels were evaluated by quantitative real-time polymerase chain reaction. GA733-1/-2 gene expression in noncancerous/cancerous tissues was also correlated with clinicopathological parameters. The GA733-1 mRNA levels were very low; however, the GA733-1 mRNA transcripts were higher in cancerous tissues than in normal tissues (median ratio, 0.004391/0.00093; range, 0.000001- 0.025139/0.000001-0.007761), respectively (P = 0.012). GA733-2 gene expression was higher in noncancerous tissues than in cancerous tissues (median ratio 273.31/115.64; range, 65.24-1,486.41/11.58-1,189.14; P = 0.0000195). Lower GA733-2 expression in cancer tissues appeared to correlate with lymph node metastases (P < 0.05). GA733-1 gene expression was significantly higher in cancerous samples; conversely, the GA733-2 mRNA levels were higher in noncancerous tissues, and were significantly correlated with lymph node perforation in colorectal cancer (P < 0.05). Therefore, GA733-1/-2 mRNA expression levels appear to be a potential predictive marker of tumorigenesis. © FUNPEC-RP.

musculoskeletal diseases - Abstract
Introduction: Femoral head avascular necrosis (AVN) is a recalcitrant disease of the hip that leads to joint destruction. Osteoprotegerin (OPG), Receptor Activator of Nuclear Factor kappa-B (RANK) and RANK ligand (RANKL) regulate the balance between osteoclasts-osteoblasts. The expression of these genes affects the maturation and function of osteoblasts-osteoclasts and bone remodeling. In this study, we investigated the molecular pathways leading to AVN by studying the expression profile of OPG, RANK and RANKL genes. Material and methods: Quantitative Real Time-PCR was performed for evaluation of OPG, RANK and RANKL expression. Analysis was based on parallel evaluation of mRNA and protein levels in normal/necrotic sites of 42 osteonecrotic femoral heads (FHs). OPG and RANKL protein levels were estimated by western blotting. Results: The OPG mRNA levels were higher (insignificantly) in the necrotic than the normal site (p. >. 0.05). Although the expression of RANK and RANKL was significantly lower than OPG in both sites, RANK and RANKL mRNA levels were higher in the necrotic part than the normal (p.

- Abstract
Objective: Chondrocyte signaling is widely identified as a key component in cartilage homeostasis. Dysregulations of the signaling processes in chondrocytes often result in degenerative diseases of the tissue. Traditionally, the literature has focused on the study of major players in chondrocyte signaling, but without considering the cross-talks between them. In this paper, we systematically interrogate the signal transduction pathways in chondrocytes, on both the phosphoproteomic and cytokine release levels. Methods: The signaling pathways downstream 78 receptors of interest are interrogated. On the phosphoproteomic level, 17 key phosphoproteins are measured upon stimulation with single treatments of 78 ligands. On the cytokine release level, 55 cytokines are measured in the supernatant upon stimulation with the same treatments. Using an Integer Linear Programming (ILP) formulation, the proteomic data is combined with a priori knowledge of proteins' connectivity to construct a mechanistic model, predictive of signal transduction in chondrocytes. Results: We were able to validate previous findings regarding major players of cartilage homeostasis and inflammation (e.g., IL1B, TNF, EGF, TGFA, INS, IGF1 and IL6). Moreover, we studied pro-inflammatory mediators (IL1B and TNF) together with pro-growth signals for investigating their role in chondrocytes hypertrophy and highlighted the role of underreported players such as Inhibin beta A (INHBA), Defensin beta 1 (DEFB1), CXCL1 and Flagellin, and uncovered the way they cross-react in the phosphoproteomic level. Conclusions: The analysis presented herein, leveraged high throughput proteomic data via an ILP formulation to gain new insight into chondrocytes signaling and the pathophysiology of degenerative diseases in articular cartilage. © 2014 Osteoarthritis Research Society International.

ABSTRACT The aim of this study was to optimize the dextranase production by fungus Pochonia chlamydosporia (VC4) and evaluate its activity in dextran reduction in sugarcane juice. The effects, over the P. chlamydosporia dextranase production, of different components from the culture medium were analyzed by Plackett-Burman design and central composite design. The response surface was utilized to determine the levels that, among the variables that influence dextranase production, provide higher production of these enzymes. The enzymatic effect on the removal of dextran present in sugarcane juice was also evaluated. It was observed that only NaNO3 and pH showed significant effect (p

Large cities have been facing serious problems in the management of traffic, owing to the increasing number of vehicles and pedestrians. Traffic engineering is essential in managing traffic and improving urban mobility. This paper deals with the problem of fixed-time signal programming on traffic networks. A new bi-objective optimization model is proposed to maximize the average and minimize the variance of the vehicle speeds in the network. Although the first function is commonly discussed in the literature, the second one is novel, and its aim is to provide flow balance along the network. This combination of functions is optimized by the Memory-Based Variable-Length Nondominated Sorting Genetic Algorithm 2 (MBVL-NSGA2), which avoids the revaluation of candidate solutions. This approach was validated through experiments using the microscopic simulator GISSIM, in a multi-intersection real network, using measured data from Belo Horizonte traffic engineering company (BHTRANS). The practical results of MBVL-NSGA2 were compared with four approaches: (1) current BHTRANS solutions; (2) a genetic algorithm optimizing the first function; (3) a genetic algorithm optimizing the second function, and; (4) the traditional NSGA2. Analysis showed that this proposal is able to generate better traffic signal plans, at the same time that it generates a diversified set of efficient candidate solutions. [ABSTRACT FROM AUTHOR]

Avascular necrosis (AVN) is a disorder of the bone repair process which usually results in femoral head (FH) destruction. Bone morphogenetic proteins (BMPs) are the key proteins regulating bone remodelling and healing. BMPs gene expression levels were analyzed in the normal and necrotic sites of osteonecrotic FHs. Quantitative RT-PCR for BMP-2, -4, -6, -7 genes was performed in bone tissue samples from 47 osteonecrotic FHs. Protein levels of BMP-2, -4, -6 were estimated by Western Blot. Statistical analysis was performed using the Wilcoxon signed rank test. BMP-2 and BMP-6 mRNA levels were higher in the normal than the necrotic site (normal/necrotic: 16.8/6.8 and 1.75/1.64, respectively). On the contrary, BMP-4 mRNA levels were higher in the necrotic (0.75) than the normal (0.62), while BMP-7 mRNA levels were extremely low. At the protein level, BMP-2 continued to have a higher expression in the normal region (normal/necrotic: 0.67/0.64). BMP-4 and -6 were detected at higher levels in the necrotic site (normal/necrotic: 0.51/0.61 for BMP-4, 0.51/0.56 for BMP-6), while BMP-7 was not detectable. Different BMP levels between the normal and necrotic site, as well as discrepancies between the gene and protein expression pattern suggest a different regulation mechanism for BMPs between the two regions of FHs. The understanding of the expression pattern and the correlation of BMPs could lead to a more successful use in the prevention and treatment of AVN. © 2013 Springer Science+Business Media Dordrecht.

musculoskeletal diseases - Abstract
Background: Osteoporosis has a multifactorial pathogenesis characterized by a combination of low bone mass and increased fragility. In our study, we focused on the effects of polymorphisms in CER1 and DKK1 genes, recently reported as important susceptibility genes for osteoporosis, on bone mineral density (BMD) and bone markers in osteoporotic women. Our objective was to evaluate the effect of CER1 and DKK1 variations in 607 postmenopausal women. The entire DKK1 gene sequence and five selected CER1 SNPs were amplified and resequenced to assess whether there is a correlation between these genes and BMD, early menopause, and bone turnover markers in osteoporotic patients. Results: Osteoporotic women seem to suffer menopause 2 years earlier than the control group. The entire DKK1 gene sequence analysis revealed six variations. There was no correlation between the six DKK1 variations and osteoporosis, in contrast to the five common CER1 variations that were significantly associated with BMD. Additionally, osteoporotic patients with rs3747532 and rs7022304 CER1 variations had significantly higher serum levels of parathyroid hormone and calcitonin and lower serum levels of osteocalcin and IGF-1. Conclusions: No significant association between the studied DKK1 variations and osteoporosis was found, while CER1 variations seem to play a significant role in the determination of osteoporosis and a potential predictive role, combined with bone markers, in postmenopausal osteoporotic women. © 2013 Koromila et al.

So, this study aimed to verify the occurrence of the BVDV-1 (SINGER) and BVDV-2 (VS-253) genotypes in cows and their respective fetuses, slaughtered in an abattoir in the State of Sao Paulo. Through blood serum, using virus neutralization technique. All in all, 52,51% (115/219) of the cows which were tested reacted, but no fetus (0/219) reacted, to its virus neutralization. Through this cross-examination we observed that 42% (92/219) of cows reacted for both BVDV-1 and BVDV-2. Furthermore 4,10% (9/219) of them reacted only to the genotype BVDV-1 and 6,39% (14/219) responded only to the genotype 2 of BVDV. Therefore it was noticed that both strains are widespread in the regions studied, which justifies the use of different antigens to avoid false-negative diagnosis. Finally antibodies showed no fetus or fetal abnormalities, it is already developed and can be considered immunocompetent, independent child born to a reagent.
