Evaluation of time-series registration methods in dynamic area telethermometry for breast cancer detection

Automated motion reduction in 3D dynamic infrared imaging is on demand in many applications. Few methods for registering time-series dynamic infrared frames have been proposed. Almost all such methods are feature based algorithms requiring manual intervention. We apply different automated registration methods based on spatial displacement to 11 datasets of Breast Dynamic Infrared Imaging (DIRI) and evaluate the results in terms of both the image similarity and anatomical consistency of the transformation. The aim is to optimize the registration strategy for breast DIRI in order to improve the spectral analysis of temperature modulation; thus facilitating the acquisition procedure in a Dynamic Area Telethermometry framework. The results show that symmetric diffeomorphic demons registration outperforms both warped frames similarity and smoothness of deformation fields; hence proving effective for time-series dynamic infrared registratio

RNAi-related genes in Toxoplasma gondii.

RNA interference (RNAi) is an evolutionarily conserved mechanism through which double-stranded RNA (dsRNA) triggers degradation of homologous transcripts. Argonaute proteins and small interfering RNAs (siRNAs) are the known signature components of the RNAi effector complex, named RNA-induced silencing complex (RISC). Our group previously reported that dsRNA-induced specific gene silencing is functional in Toxoplasma gondii, an intracellular parasite of humans and other mammals. In the present study, we describe the characterization of the first Argonaute protein (TgAgo) in T. gondii. The cDNA clone has an open reading frame (ORF) of 1575 bp which encodes a putative 524-amino-acid protein with a calculated molecular weight of 58.5 kDa and an estimated isoelectric point (pI) of 9.4. Using bioinformatic methods, we found significant homology between the Piwi domains of TgAgo and previously reported Argonaute proteins, but were unable to locate a PAZ domain. Polyclonal antibodies raised against TgAgo peptides have recognized a protein of the expected size (58.5 kDa), which was mainly localized in the cytoplasm. (Abstract shortened by UMI.)

Preoperative Systems for Computer Aided Diagnosis based on Image Registration: Applications to Breast Cancer and Atherosclerosis

Computer Aided Diagnosis (CAD) systems assist clinicians including radiologists and cardiologists to detect abnormalities and highlight conspicuous possible disease. Implementing a pre-operative CAD system contains a framework that accepts related technical as well as clinical parameters as input by analyzing the predefined method and demonstrates the prospective output. In this work we developed the Computer Aided Diagnostic System for biomedical imaging analysis of two applications on Breast Cancer and Atherosclerosis. The aim of the first CAD application is to optimize the registration strategy specifically for Breast Dynamic Infrared Imaging and to make it user-independent. Base on the fact that automated motion reduction in dynamic infrared imaging is on demand in clinical applications, since movement disarranges time-temperature series of each pixel, thus originating thermal artifacts that might bias the clinical decision. All previously proposed registration methods are feature based algorithms requiring manual intervention. We implemented and evaluated 3 different 3D time-series registration methods: 1. Linear affine, 2. Non-linear Bspline, 3. Demons applied to 12 datasets of healthy breast thermal images. The results are evaluated through normalized mutual information with average values of 0.70±0.03, 0.74±0.03 and 0.81±0.09 (out of 1) for Affine, BSpline and Demons registration, respectively, as well as breast boundary overlap and Jacobian determinant of the deformation field. The statistical analysis of the results showed that symmetric diffeomorphic Demons registration method outperforms also with the best breast alignment and non-negative Jacobian values which guarantee image similarity and anatomical consistency of the transformation, due to homologous forces enforcing the pixel geometric disparities to be shortened on all the frames. We propose Demons registration as an effective technique for time-series dynamic infrared registration, to stabilize the local temperature oscillation. The aim of the second implemented CAD application is to assess contribution of calcification in plaque vulnerability and wall rupture and to find its maximum resistance before break in image-based models of carotid artery stenting. The role of calcification inside fibroatheroma during carotid artery stenting operation is controversial in which cardiologists face two major problems during the placement: (i) “plaque protrusion” (i.e. elastic fibrous caps containing early calcifications that penetrate inside the stent); (ii) “plaque vulnerability” (i.e. stiff plaques with advanced calcifications that break the arterial wall or stent). Finite Element Analysis was used to simulate the balloon and stent expansion as a preoperative patient-specific virtual framework. A nonlinear static structural analysis was performed on 20 patients acquired using in vivo MDCT angiography. The Agatston Calcium score was obtained for each patient and subject-specific local Elastic Modulus (EM) was calculated. The in silico results showed that by imposing average ultimate external load of 1.1MPa and 2.3MPa on balloon and stent respectively, average ultimate stress of 55.7±41.2kPa and 171±41.2kPa are obtained on calcifications. The study reveals that a significant positive correlation (R=0.85, p<0.0001) exists on stent expansion between EM of calcification and ultimate stress as well as Plaque Wall Stress (PWS) (R=0.92, p<0.0001), comparing to Ca score that showed insignificant associations with ultimate stress (R=0.44, p=0.057) and PWS (R=0.38, p=0.103), suggesting minor impact of Ca score in plaque rupture. These average data are in good agreement with results obtained by other research groups and we believe this approach enriches the arsenal of tools available for pre-operative prediction of carotid artery stenting procedure in the presence of calcified plaques

Lie-isoclinism of pairs of Leibniz algebras

The aim of this paper is to consider the relation between Lie-isoclinism and isomorphism of two pairs of Leibniz algebras. We show that, unlike the absolute case for finite dimensional Lie algebras, these concepts are not identical, even if the pairs of Leibniz algebras are Lie-stem. Moreover, throughout the paper, we provide some conditions under which Lie-isoclinism and isomorphism of Lie-stem Leibniz algebras are equal. In order to get this equality, the concept of factor set is studied as well.Agencia Estatal de Investigación | Ref. MTM2016-79661-

Unusual Abdominal Ectopic Pregnancy Implantation in the Vesicouterine Pouch: A Case Report

Background: &nbsp;Primary abdominal ectopic pregnancy is a very&nbsp; rare condition that occurs when the gestational sac is implanted directly into the abdominal peritoneum. In many cases it is difficult to have an exact diagnosis before explorative and therapeutic&nbsp; laparotomy or laparoscopic surgery and most of them are diagnosed during surgery. It can be a life threatening condition with high morbidity due to misdiagnosis or mismanagement. Cases Report: A 36 -year-old Iranian woman was admitted to Mahdieh hospital emergency department of shahid Beheshti medical science university (Tehran, Iran) with vaginal spotting and abdominal right lower quadrant pain with a background history of 6 weeks’ amenorrhea and a significant beta-human chorionic gonadotropin of 26660 IU/L. Subsequent transvaginal sonography revealed paraovarian fluid and 20×23 hyperheteroechoic right adnexal mass with peripheral vascularity indicating probable ectopic pregnancy. Following that, she underwent diagnostic and therapeutic laparotomy. It showed 400 cc blood and 50 cc clot in vesicouterine pouch that were suctioned. There was no evidence of right adnexal ectopic pregnancy however a resemblance of trophoblastic tissue was located on the wall of uterovesical pouch on the omentum. &nbsp;Conclusion: We conclude that emergency laparotomy or laparoscopic surgery should be done to prevent occurrence of uncontrollable bleeding. Also utilizing MRI can be beneficial for exact detection the site of ectopic pregnancy before surgery which can be useful&nbsp; for perioperative planning and management of this condition
