The conus coronary artery has been reported to arise independently from the aorta in approximately 45 per cent of hearts. In this study, 305 necropsy specimens were examined to determine the origin of the conus coronary artery and variations in patterns of origin with respect to age. Three patterns were recognised: 1, in which the conus artery arose from the aorta independently of the right cor...

A 1-year and 11-month- old English Cocker Spaniel was evaluated for clinical signs of progressive right pelvic limb lameness and urinary incontinence. Neurological examination was suggestive of a lesion localized to the L4-S3 spinal cord segments. No abnormalities were seen on magnetic resonance imaging (MRI) performed in the dog in dorsal recumbency and the hips in a neutral position and the c...

The marine environment presents much danger, specifically in regards to the numerous venomous inhabitants within tropical and subtropical waters. The toxins from one such group of venomous marine snails, commonly referred to as 'cone snails', have been well documented in causing human fatalities. Yet information regarding medical treatment for cone snail envenomation is limited and poorly acces...

PURPOSE In the current report, we describe a case of an extramedullary ependymoma involving a lumbar nerve root near conus medullaris. Spinal ependymomas commonly present as intramedullary tumors in the cervical or thoracic cord or as tumors arising from the conus medullaris or the filum terminale. In this case, we showed an extramedullary conus ependymoma involving a lumbar nerve root with fil...

Neuronal nAChRs are a diverse family of pentameric ion channels with wide distribution throughout cells of the nervous and immune systems. However, the role of specific subtypes in normal and pathological states remains poorly understood due to the lack of selective probes. Here, we used a binding assay based on acetylcholine-binding protein (AChBP), a homolog of the nicotinic acetylcholine lig...

A number of articles written in recent years about the pattern of blood flow through the amphibian heart have described results which differ quite widely (Simons, 1957, 1959; de Graaf, 1957; Johansen, 1963; Shelton & Jones, 1965a, b). One of the main difficulties in interpretation has been that all the work cited above has been done on different species of anuran and urodele. It is clearly poss...

Our country’s textile industry is in the producing and processing field in the global value chain, so textiles’ added value is low and profit margins is narrow. Developed countries take up fields of high-grade fabrics production and advanced textile machinery manufacture. Because textile fabrics, textile machinery and equipment of China's textile industry fall behind developed countries, produc...

Coronary artery fistulas are rare coronary-cardiac anomalies, which occasionally become symptomatic. We herein report a case of a 54-year-old woman with a huge conus branch aneurysm resulting from an abnormal fistula between the conus branch and the upper portion of the right atrium, which was successfully removed by surgery.

Adolescent idiopathic scoliosis (AIS) is a structural 3-dimensional deformity the spine, which is occurring between 10 years of age and skeletal maturity and it mostly affects prepuberbal girls. The etiology of AIS remains unknown and seems should be multifactorial. According to the theories, there could be a shorter spinal cord or a higher location of the conus medullaris and disproportionate ...

Intravascular large B-cell lymphoma (IVLBCL) is a rare non-Hodgkin lymphoma with variable clinical manifestations. Although neurological symptoms are common in patients with IVLBCL, isolated cauda equina-conus medullaris syndrome is rarely reported. We herein report a case of IVLBCL whose initial presentation was cauda equina-conus medullaris syndrome with neither dermatological nor hematologic...
