The horseshoe crabs, known as living fossils, have maintained their morphology almost unchanged for the past 150 million years. The little morphological differentiation among horseshoe crab lineages has resulted in substantial controversy concerning the phylogenetic relationship among the extant species of horseshoe crabs, especially among the three species in the Indo-Pacific region. Previous ...

Hibernation is an energy-saving strategy which is widely adopted by heterothermic mammals to survive in the harsh environment. The greater horseshoe bat (Rhinolophus ferrumequinum) can hibernate for a long period in the hibernation season. However, the global gene expression changes between hibernation and non-hibernation season in the greater horseshoe bat remain largely unknown. We herein rep...

Sexual size dimorphism (SSD) is widespread within the animal kingdom. Rensch's rule describes a relationship between SSD and body size: SSD increases with body size when males are the larger sex, and decreases with body size when females are the larger sex. Rensch's rule is well supported for taxa that exhibit male-biased SSD but patterns of allometry among taxa with female-biased size dimorphi...

We study the torque on low mass protoplanets on fixed circular orbits, embedded in a protoplanetary disc in the isothermal limit. We consider a wide range of surface density distributions including cases where the surface density increases smoothly outwards. We perform both linear disc response calculations and non linear numerical simulations. We consider a large range of viscosities, includin...

BACKGROUND AND OBJECTIVES Horseshoe kidney is a relatively common renal fusion anomaly. There are increasing reports of successful laparoscopic management of surgical disease in this entity. Xanthogranulomatous pyelonephritis (XGP) is an inflammatory condition of chronically obstructed and infected kidneys that is typically refractory to medical management. XGP has been regarded as a contraindi...

BACKGROUND Although a few cases with idiopathic horseshoe-like macular tear have been reported, the mechanism remains unknown and a standard treatment has yet to be determined. OBJECTIVE To report the outcome for a patient with idiopathic horseshoe-like macular tear who underwent vitreous surgery. CASE REPORT A 65-year-old man with no previous injury or ophthalmic disease presented with abn...

Horseshoe kidney is a congenital defect of the urinary tract that occurs in 0.25% of the general population. The indications for division of the isthmus of horseshoe kidney are controversial, and if done, it is during the concomitant removal of additional defects accompanying horseshoe kidney. The aim of this study was to evaluate the results of isthmusectomy of horseshoe kidney using laparosco...

amiodarone is used in treatment of cardiac arrhythmias. therapeutic use of amiodarone is limited by its side effects, including pulmonary toxicity. human placenta extract (hpe) contains a variety of bio-active substances. thus, the present study aimed to quantitatively evaluate the protective effects of hpe on the structural lung changes induced by amiodarone using stereological methods. spragu...
