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...

Horseshoe kidney is the most common of all renal fusion anomalies, occurring in approximately 0.25% of the general population. Horseshoe kidney with only a single ureter is a rare anomaly. A 60-year-old man was admitted to hospital for routine health screening. His family history was negative for kidney diseases, and there was no abnormality in his physical examination. A computed tomography (C...

Hydronephrosis is a common finding in urinary tract outflow obstruction. Chronically obstructed hydronephrotic system may be associated with parenchymal changes. Ultrasound, intravenous urography, micturating cysto-urethrogram and scintigraphy are commonly performed to evaluate the cause of obstruction. In childhood, pelviureteric junction obstruction is a common cause of the hydronephrosis. Hy...

The horseshoe+ estimator for Gaussian linear regression models is a novel extension of the horseshoe estimator that enjoys many favourable theoretical properties. We develop the first efficient Gibbs sampling algorithm for the horseshoe+ estimator for linear and logistic regression models. Importantly, our sampling algorithm incorporates robust data models that naturally handle non-Gaussian dat...

The horseshoe kidney is a congenital fusion anomaly of the kidneys with an incidence of 0.25% in the general population. We present an anatomical and histological study of a horseshoe kidney with abnormal vascular supply found during a routine dissection at a formalin-fixed male human body at the School of Medicine of the University of Caxias do Sul. This horseshoe kidney was joined at the lowe...
