Duplication anomalies are quite common with ureteral duplication anomalies being the most frequent. Despite the relatively frequent incidence of a horseshoe kidney and duplication anomalies in any individual patient, the combination of horseshoe kidney and bilateral ureteric duplication is a very rare entity and very few cases have been reported to date. We present a case of a patient with nove...

Unlike Trojans, horseshoe co-orbitals are not generally considered to be long-term stable. As the lifetime of Earth’s and Venus’s horseshoe co-orbitals is expected to be about a Gyr, we investigated the possible contribution of late-escaping inner planet co-orbitals to the lunar Late Heavy Bombardment. Contrary to analytical estimates, we do not find many horseshoe objects escaping after the fi...

The authors present a detailed analysis of the asymptotic frequentist properties of credible sets derived from posteriors with normal-linear measurement models and horseshoe priors. Although we disagree with the claim that “In Bayesian practice credible balls are nevertheless used as if they were confidence sets”, the results in the paper are important for identifying where the horseshoe priors...

A 17 years unmarried female presented to Gastroenterology Department of our hospital for nonspecific symptoms of epigastric pain. The Ultrasonographic examination of the patient revealed triple kidney with horseshoe anomaly. She was then referred to us for further evaluation. We further proceed with Intravenous Urography (IVU) which demonstrated a bilateral duplex system in a asymmetrical horse...

A 32-year-old man was examined for primary infertility. Ultrasound and computed tomography (CT) abdomen scans showed the presence of polycystic horse shoe kidney (Figure 1). CT abdomen revealed cysts in liver and seminal vesicles (Figure 2). There were bilateral ureteric calculi. There were no cysts in the pancreas or spleen. His serum creatinine level was 0.9 mg/dL (79.6 mmol/L). The patient h...

Biomedical companies catch and bleed horseshoe crabs for the production of Limulus amebocyte lysate (LAL), a product used for protecting public health (Berkson and Shuster, 1999). LAL is a clotting agent, derived solely from horseshoe crab blood cells, which is used to detect the presence of pathogenic gramnegative bacteria in injectable drugs and implantable medical and dental devices (Mikkels...

◦ Geodesic flows on compact manifolds with negative sectional curvature. Later, we relax uniform hyperbolicity to an asymptotic one, called non-uniform hyperbolicity. Two examples of such systems are: ◦ Slow down of fA : T → T, see [9]. ◦ Geodesic flows on surfaces with nonpositive curvature. Introductory example: Smale’s horseshoe [21]. Let g : K → K be Smale’s horseshoe map, and σ : Σ→ Σ the ...

The zoological collection of the National Museum, Prague (NMP) contains spirit (juvenile) as well as dry (mostly adult) specimens of horseshoe crabs (Xiphosura). Living horseshoe crabs are of immunological importance due to clotting agents present in their hemolymph. Here we summarize basic data about the mechanism of the immune system of these marine animals and its use in practice – the Limul...

In this paper we present a particular history of Limulus polyphemus, the horseshoe crab, as a means of expanding on Haraway’s notion of companion species. Drawing on accounts of the horseshoe crab’s role, on the one hand, in work of the Serological Museum at Rutgers University that spanned the 1940s to the 1970s, and, on the other, in the development of the limulus amebocyte lysate test, we tra...
