Biomechanical and morphological peculiarities of the rectum in patients with obstructed defecation syndrome Ints Brunenieks, Katrina Pekarska, Vladimir Kasyanov, Valerija Groma The morphological and biomechanical peculiarities of the rectum observed in obstructed defecation syndrome ODS are not completely understood.

Gastric cancer hereditary biomechanical properties and morphological features of gastric cancer hereditary rectum in patients with ODS in correlation with gastric cancer hereditary status of the enteric nervous system ENS were evaluated. Uniaxial tensile tests on the rectum samples of patients with ODS and controls were performed; collagenous constituents were assessed by Reticulin and Masson s trichrome stainings; gastric cancer hereditary expressions of alpha-smooth muscle actin alpha-SMAS and CD labeling of interstitial cells of Cajal ICCs were investigated by immunohistochemistry.

In both groups, the ultimate stress in the posterior rectal wall was statistically significantly higher compared to the anterior one. The ultimate strain was higher in ODS compared to controls.

The results of biomechanical properties and morphological changes in the human rectum are essential when choosing the method of ODS treatment. Spatiotemporal expression of extracellular matrix components during the chondrogenic and osteogenic phases of bone healing Moyses Messias Souza de Sant Anna, Luiz Alberto Batista, Thais Cristina Mendes da Silva, Liszt Palmeira Oliveira, Jorge Jose de Carvalho In this study, we investigated the cascade of events involved in the early phases of bone healing in rats, especially the transition from chondrogenesis to osteogenesis, which involves cellular and extracellular matrix Gastric cancer hereditary components.

We used a standardized closed tibial fracture model in Wistar rats, which was divided into nine groups of five animals each, and the fracture area was evaluated at 0, 12, 24, 48, 72, 96, and hours post-injury.

Histological, gastric cancer hereditary, immunohistochemical and morphometric techniques were used to evaluate the proliferating cell nuclear antigen PCNAtransforming growth factor-beta TGF-betavascular endothelial growth factor VEGFtype I procollagen procoll-Itype I collagen coll-Iand type II collagen coll-II expression at every time point.

Gastric cancer hereditary results suggest that spatiotemporal expression of ECM components during the chondrogenic and osteogenic phases of bone healing depends on several combined and orchestrated factors. A better understanding of the coordinated participation of cells and ECM components in the early bone healing process may provide new insights into the etiology of abnormal or delayed fracture healing.

The aim of this paper is the possibility of differentiating the bone lesions from hematological malignancies by other malignancies that give bone metastases for the purpose to guide the clinician concerning causality of bone lesions.

The research involved a retrospective study, which included cases that were investigated by magnetic resonance imaging MRI at a segment of the spine, between andfrom which were diagnosed with a form of hematological neoplasia, and the remaining had another form of cancer. Imaging aspect differs in these two study groups.

Bone determinations due to malignant hemopathies MH gastric cancer hereditary in general hypointense on T1-weighted sequences, iso- or hyperintense on T2-weighted sequences.

Aggressive variants of prostate cancer - Are we ready to apply specific treatment right now? Cancer Treat Rev. In most cases, prostate cancer essentially depends on androgen receptor signaling axis, even in castration-resistant setting, and hence may be targeted by second generation hormonal therapy.

On the other hand, bone metastases were hypo- or isointense on T1-weighted sequences, and had no specific signal gastric cancer hereditary on T2-weighted sequences. In post-contrast images, all lesions showed contrast enhancement, with some differences.

In terms of imagistic aspect, there are certain characteristics that can make a clear differentiation gastric cancer hereditary bone determinations due to MH from the bone metastases, and some are found in the majority of the cases studied. The present study aims to compare the difference in pathology, blood gas values and biomarkers of two acute lung injury rat models at different time intervals.

In the experiment, rats were randomly divided into three groups: lipopolysaccharide LPS group, oleic acid OA group and control group.

Changes of pathology, blood gas values and blood-air barrier biomarkers were analyzed at 15 minutes, 6 hours, 12 hours and 24 hours after injection. The results showed that the two models exhibited different features. Compared with the LPS rats, OA rats exhibited significantly severe pathological changes, lower arterial oxygen partial pressure PaO2 value and higher level of injury biomarkers.

This study suggests that LPS-induced model has greater value in researches on microcirculation dysfunction and sepsis resulting from ALI, while OA-induced model has greater repeatability in area of gas exchanging after ALI.

Comparing the antifibrotic effect on the liver of Telmisartan cheloo revelion Pentoxifylline, in a Wistar rat experimental model Floriana Elvira Ionica, Laurentiu Mogoanta, Simona Negres, Ludovic Everard Bejenaru, Oana Mariana Cristea, Oana Badea, Cornelia Bejenaru Chronic liver diseases are characterized by higher or lower changes of the liver lobe architecture parenchymatous and vacuolarthe accumulation of inflammatory and collagen infiltrates, mainly in the Kiernan spaces and a progressive evolution to liver cirrhosis.

Despite the progresses made in knowing the mechanisms of liver fibrosis and the development of some antiviral drugs with a high potential, that can induce fibrosis regression, there still continues to exist the need for a specific antifibrotic treatment.

A 3-Nitropropionic acid 3NP irreversibly inhibits mitochondrial complex II in the electron transport chain, with subsequent loss of transmembrane potential and calcium entry into the mitochondria. The expression of OPN in the striatum of 3NP-treated rats was gastric cancer hereditary with immunohistochemistry and immunoelectron microscopy. In the striatal lesions, extensive loss of neurons and white matter bundles was detected. OPN was mainly detected in the penumbra region of the 3NP lesion.

Scattered OPN expression was colocalized in the striatal neurons. After Alizarin Red S staining, the increase of calcium deposition was detected in the striatal lesions. In the electron microscopic analysis, the localization of OPN was clearly observed in the ultrastructure of mitochondria by immunoperoxidase and immunogold-silver staining techniques.

Taken together, present findings suggest that calcium-induced mitochondrial swelling is highly associated with OPN expression. Thus, striatal calcium accumulation may be derived from 3NP-induced alteration in mitochondrial calcium homeostasis and pathologically associated with the induction of OPN protein.
