Immunologic Evaluation of Ectopic Gestation
<p>Ectopic gestation is an error in the implantation site of the blastocyst. Extrauterine implantation presents a unique environment since the protective features of the uterus are absent. This study is an investigation into the immunoregulatory differences that may develop as a result of a change …

The Genetic Aetiology of Ectopic Maxillary Canine Teeth
Introduction. The ectopic canine (EC) is a common clinical complication of dental development appearing in 1-2% of the Western population The aetiology is controversial with opinion divided as to a genetic or environmental mechanism. This study addresses the hypothesis that genetic factors play an …

Machine learning for patient-adaptive ectopic beat classification
Physicians require automated techniques to accurately analyze the vast amount of physiological data collected by continuous monitoring devices. In this thesis, we consider one analysis task in particular, the classification of heartbeats from electrocardiographic recordings (ECG). This problem is …

The Temporal Nature of Ectopic Activity in Guinea Pig Ventricular Myocardium
The temporal nature of ectopic activity is important to elucidating the mechanisms that can lead to arrhythmogenesis. However, challenges remain in distinguishing between ectopic and non-ectopic beats. A new methodology was developed and validated to distinguish between beat types. Rapid pacing was …

Developing an Inducible Osteoclast System as a Cell Therapy for Ectopic Calcification
Ectopic calcification (EC) is a complex disease in which mineral develops in abnormal locations. It can develop in a variety of locations throughout the body, including the vasculature, heart valves, and in orthopedic settings where it is more commonly referred to as heterotopic ossification (HO). …

Manipulation of second messengers by ectopic expression of receptors in transgenic Drosophila
… in principal cells. This study has validated ectopic transgene expression as a generic technology with potential beyond Malpighian tubules: in principle, such transgenes can be expressed specifically in any population of cells that can be delineated by a GAL4 driver line.

Ectopic Vas deferens as an incidental finding in a patient with VACTERL association
La ectopia del conducto deferente es una anomalía congénita poco común, usualmente se encuentra asociada a otras anomalías congénitas del tracto urinario y anorectales. Puede tener repercusiones dadas por infecciones recurrentes urogenitales. Los casos presentados en la literatura son reducidos y …

Ovarian Response, Embryo Quality and Ectopic Pregnancy // Овариален отговор, качество на ембрионите и извънматочна бременност
Направен е ретроспективен и проспективен анализ на 1077 бременности след 2602 не-донорски IVF/ICSI свежи и размразени цикли, като са сравнени две основни групи спрямо изхода от АРТ - 976 случая (91%) вътрематочна бременност срещу 101 случая (9%) извънматочна бременност. Приложените методики бяха …

In Vivo Studies of Yeast Mitochondrial Intron Splicing : Ectopic Branching and a Screen for Nuclear Encoded Splicing Factors
… the efficiency and fidelity of branching at the ectopic branch A. However, for the shifted down ectopic branch A, it is not the presence of the GU pair flanking the branch that restores branching but the presence of a GC pair located two base-pairs above the branch. This finding is consistent …

The C. elegans class A synthetic multivulva genes inhibit ectopic RAS-mediated vulval development by tightly restricting expression of lin-3 EGF
… antagonize an EGF/Ras pathway to prevent ectopic vulval induction. The class B synMuv genes encode many proteins known to remodel chromatin and repress transcription. The class A synMuv genes likely also function in transcription, although their specific molecular functions are unknown. We …

Ectopic pregnancy occurs when the embryo implants outside the uterine cavity. Although mortality rates associated with ectopic pregnancy have declined in recent years, it remains the leading cause of maternal death during the first trimester of pregnancy. It affects approximately 2% of pregnant …

Synchronous rhythms in coronary heart disease: an hypothesis concerning the anomalous nature of some common ventricular arrhythmias - investigation with an electronic analogue
… containing frequent, single ventricular ectopic complexes are investi¬ gated using 24 hour tape recordings of ECGs, High-speed electronic analysis of records containing such complexes reveal characteristics difficult to reconcile with existing theories of the origin of these beats. A …

Integrin Alpha Subunit Ratios, Cytoplasmic Domains, and Growth Factor Synergy Regulate Muscle Proliferation, Differentiation, and Signaling
… in muscle differentiation was addressed by ectopic expression of integrin alpha subunits in primary quail skeletal muscle. Ectopic expression of either the human or $\alpha$5 or the chicken $\alpha$6 subunit produced contrasting phenotypes. The $\alpha$5 transfected myoblasts remain in the …
