AbstractA free-swimming thornback ray Raja clavata specimen demonstrating significant morphological abnormality is reported, captured by beam trawl in the Irish Sea off north Wales, UK. The anterior sections of both pectoral fins were separated from the head section for a length of approximately 140 mm extending from the rostrum tip to a point posterior of the spiracles, along with abnormal morphology of the gill slits. This phenomenon has been observed elsewhere but is the first documented example of this abnormality in the eastern Irish Sea, despite widespread targeting of the species across the region by commercial and recreational fishers. Possible causes and consequences of the observed abnormality are discussed.

Abstract Raramuri Criollo (RC) are one of 33 known biotypes of heritage Criollo cattle that exist throughout the Americas today. They have been raised by the Tarahumara peoples of the Copper Canyon in Chihuahua, Mexico, for over 400 years and exhibit remarkable rusticity and adaptation to harsh grazing environments. To date, no quantitative phenotypic description of this biotype exists. Our objective was to characterize RC cattle via 26 phenotype traits to provide a preliminary biotype standard. Twenty-eight multiparous RC cows, 4 primiparous heifers, and 4 bulls were selected from a purebred herd of approximately 200 animals at the USDA-ARS Jornada Experimental Range. These 36 animals were selected by a Criollo cattle expert based on body conformation correctness. SAS 9.4 was used to determine means, SEs or frequency of measured traits. Multiparous pregnant and cycling cows averaged 366.8 ± 9.8 kg live body weight, 121.8 ± 0.9 cm withers height, horn widths of 60.3 ± 1.6 cm, horn diameters of 5.7 ± 0.1 cm, chest girths of 183.6 ± 12.0 cm, hip widths of 44.5 ± 0.5 cm, flank girths of 52.2 ± 0.9 cm, body length of 90.0 ± 1.7 cm, neck lengths of 52.0 ± 0.9 cm, and tail lengths of 83.3 ± 1.4 cm. Bulls consistently averaged higher values for all traits and weighed 618.2 ± 9.8 kg with scrotal circumferences of 36.8 ± 0.7 cm. RC cattle exhibited mostly convex nose bridges (89%), open-back horns (49%), black muzzles, hooves, and eyes (62, 69, and 81%, respectively), small ears (78%), oblique eyes (70%), high-set tail heads (86%), short hooves (95%), and short hair (78%). Our preliminary characterization of RC phenotypes will be useful in selecting RC individuals for genotypic evaluation to eventually maintain a distinct purebred registry of this Criollo biotype.

The avian auditory papilla contains two classes of sensory receptor, tall hair cells (THCs) and short hair cells (SHCs), the latter analogous to mammalian outer hair cells with large efferent but sparse afferent innervation. Little is known about the tuning, transduction, or electrical properties of SHCs. To address this problem, we made patch-clamp recordings from hair cells in an isolated chicken basilar papilla preparation at 33°C. We found that SHCs are electrically tuned by a Ca2+-activated K+ current, their resonant frequency varying along the papilla in tandem with that of the THCs, which also exhibit electrical tuning. The tonotopic map for THCs was similar to maps previously described from auditory nerve fiber measurements. SHCs also possess an A-type K+ current, but electrical tuning was observed only at resting potentials positive to −45 mV, where the A current is inactivated. We predict that the resting potential in vivo is approximately −40 mV, depolarized by a standing inward current through mechanotransducer (MT) channels having a resting open probability of ∼0.26. The resting open probability stems from a low endolymphatic Ca2+ concentration (0.24 mM) and a high intracellular mobile Ca2+ buffer concentration, estimated from perforated-patch recordings as equivalent to 0.5 mM BAPTA. The high buffer concentration was confirmed by quantifying parvalbumin-3 and calbindin D-28K with calibrated postembedding immunogold labeling, demonstrating >1 mM calcium-binding sites. Both proteins displayed an apex-to-base gradient matching that in the MT current amplitude, which increased exponentially along the papilla. Stereociliary bundles also labeled heavily with antibodies against the Ca2+ pump isoform PMCA2a.

Absent ductus venosus (ADV) is a rare vascular anomaly. We describe a fetus/neonate with ADV with a partial liver defect. A 41-year-old woman was referred to our institute because of fetal cardiomegaly detected by routine prenatal ultrasound, which revealed absence of ductus venosus with an umbilical vein directly draining into the right atrium, consistent with extrahepatic drainage type of ADV. She vaginally gave birth to a 3,096-gram male infant at 38 weeks of gestation. Detailed ultrasound examination revealed a defect of the hepatic rectangular leaf at half a month postnatally. He showed normal development at 1.5 years of age with the liver abnormality and a Morgagni hernia. Liver morphological abnormality should also be considered as a complication of ADV.

Korneal squestrum merupakan suatu keadaan yang terjadi pada kornea yang telah mengalami kornea ulser dalam kurun waktu yang panjang/kronis. Kornea merupakan struktur pada mata bagian depan yang memiliki warna transparan dan tersusun atas outer epitelium, middle stroma dan inner endothelium. Pemeriksaan dasar yang dilakukan pada pasien adalah menace, dazzle dan pupillary reflex. Sedangkan pemeriksaan penunjang yang dilakukan adalah schiemer tear test dan fluorescein test. Hasil pemeriksaan dasar menunjukkan hasil yang positif tanpa adanya gangguan penglihatan. Sedangkan hasil fluorescein test menunjukkan hasil positif kornea ulser dengan adanya pendaran warna hijau. Terapi dilakukan dengan memberikan antibiotik (cendo genta 0,3%) s.6.d.d selama 2 minggu. Respon possitif ditunjukkan oleh pasien dengan hasil fluorescein test negatif pasca 2 minggu pengobatan. Akan tetapi, masih terdapat jaringan-jaringan berwarna putih kecoklatan yang menutupi permukaan korneal. Terapi dilanjutkan dengan memberikan cendoxitrol s.2.d.d selama 2 minggu. Respon yang diberikan pasien kurang baik, jaringan berubah menjadi kecoklatan atau disebut dengan korneal squestrum.
