Hyuksool Kwon, Jae Yun Jung
Children feature more active cellular division and a smaller body area, which leads to a greater radiation dosage accumulation. We tried to reduce radiation hazards by reducing unnecessary radiological studies in a pediatric emergency department (PED) through the radiation reduction campaign.Our campaign involved a reduction from 2 (erect and supine) to 1 ordered abdominal plain radiograph (erect). This quasi-experimental, uncontrolled before-and-after study aimed to evaluate the campaign effect. We compared simple radiograph orders, length of stay (LOS) in PED, and return visit (RV) to PED between the before period (June 1, 2011-May 30, 2014) and the after period (June 1, 2014-May 30, 2015)...

: Radical prostatectomy (RP) for prostate cancer treatment, although effective, can lead to severe erectile dysfunction. This study describes a new technique, which aims to reestablish the nerve stimulus in penile erection by two sural nerve graft bridges bilaterally, using the end to side neurorraphy. The first bridge is between femoral nerve and dorsal nerve of penis and the second, is between the femoral nerve and the interior of the corpus cavernosum. In this neurorraphy the endings of the newly formed fibres, generated by the femoral nerve, release acetylcholine inside the cavernous bodies, beginning the erection mechanism...

Based on an integrative taxonomic approach, combining morphological characters and partial sequences of the 28S rRNA gene, a new genus and species, Parasciadicleithrum octofasciatum, is proposed to accommodate dactylogyrids infecting the gills of Rocio octofasciata (Cichlidae) from a tributary of the Lacantún River basin, Chiapas State, southern Mexico. Morphologically, the new genus resembles members of Sciadicleithrum (Dactylogyridae) in the presence of membranes on the anterior margins of both ventral and dorsal haptoral bars...

Composition and temporal variation of the microphytobenthos communities of the Conero Riviera (northern Adriatic Sea) were investigated in the course of an annual cycle, focusing on their relationships with blooms of the benthic dinoflagellate Ostreopsis cf. ovata. Sampling was carried out from March 2009 to March 2010 on undisturbed benthic substrata (macroalgae and pebbles). Samples for the study of microphytobenthos were collected with a monthly frequency, while those for the study of Ostreopsis bloom weekly...

Approximately two-dozen species in three genera of the Neotropical suckermouth armored catfish family Loricariidae are the only described fishes known to specialize on diets consisting largely of wood. We conducted a molecular phylogenetic analysis of 10 described species and 14 undescribed species or morphotypes assigned to the wood-eating catfish genus Panaqolus, and four described species and three undescribed species or morphotypes assigned to the distantly related wood-eating catfish genus Panaque. Our analyses included individuals and species from both genera that are broadly distributed throughout tropical South America east of the Andes Mountains and 13 additional genera hypothesized to have also descended from the most recent common ancestor of Panaqolus and Panaque...

Red algae comprise an anciently diverged, species-rich phylum with morphologies that span unicells to large seaweeds. Here, leveraging a rich red algal genome and transcriptome dataset, we used 298 single-copy orthologous nuclear genes from 15 red algal species to erect a robust multi-gene phylogeny of Rhodophyta. This tree places red seaweeds (Bangiophyceae and Florideophyceae) at the base of the mesophilic red algae with the remaining non-seaweed mesophilic lineages forming a well-supported sister group. The early divergence of seaweeds contrasts with the evolution of multicellular land plants and brown algae that are nested among multiple, unicellular or filamentous sister lineages...

This study was undertaken to identify the cause of impotence in men undergoing radical prostatectomy, with the hope that this information may provide insight into the possible prevention of this complication. The autonomic innervation of the corpora cavernosa in the male fetus and newborn was traced to determine the topographical relationship between the pelvic nerve plexus, and the prostate, urethra and urogenital diaphragm. We have demonstrated that the branches of the pelvic plexus that innervate the corpora cavernosa are situated between the rectum and urethra, and penetrate the urogenital diaphragm near or in the muscular wall of the urethra...

The study of Eocene primates is crucial for understanding the evolutionary steps undergone by the earliest members of our lineage and the relationships between extinct and extant taxa. Recently, the description of new material from Spain has improved knowledge of European Paleogene primates considerably, particularly regarding microchoerines. Here we describe the remains of Microchoerus from Sossís (late Eocene, Northern Spain), consisting of more than 120 specimens and representing the richest sample of Microchoerus from Spain...

Heliconia (Heliconiaceae, order Zingiberales) is among the showiest plants of the Neotropical rainforest and represent a spectacular co-evolutionary radiation with hummingbirds. Despite the attractiveness and ecological importance of many Heliconia, the genus has been the subject of limited molecular phylogenetic studies. We sample seven markers from the plastid and nuclear genomes for 202 samples of Heliconia. This represents ca. 75% of accepted species and includes coverage of all taxonomic subgenera and sections...

Penile erection requires complex interaction between vascular endothelial cells, smooth muscle cells, pericytes, and autonomic nerves. Diabetes mellitus is one of the most common causes of erectile dysfunction (ED) and multiple pathogenic factors, such as cavernous angiopathy and autonomic neuropathy, are associated with diabetic ED. Although a variety of animal models of diabetic ED play an important role in understanding pathophysiologic mechanisms of diabetes-induced ED, these animal models have limitations for addressing the exact cellular or molecular mechanisms involved in ED...

REVIEW
Ahmed T Hadidi
: The evolution of hypospadias surgery can be classified under 3 periods that were closely related to advances in surgical instruments, introduction of anesthesia, and newer suture materials. Stretching dominated the early period, tunneling during the Middle Ages, and flaps during the modern period. Suture materials have included at various time silver wires, horsehair, and stainless steel. Examination and translation of the original manuscripts showed that Galen recommended stretching and suturing of glanular hypospadias and not amputation or partial penectomy as has been currently reported...

A new genus Hemiocnus is here erected to accommodate the Mediterranean dendrochirotid sea cucumber Cladodactyla syracusana Grube, currently classified, with some doubt, in the cucumariid genus Pseudocnella. At the same time a new cucumariid species, Hemiocnus rubrobrunneus, is described from some Tunisian material, misidentified as Pseudocnella syracusana (Grube), received from the United States National Museum. The new genus appears most closely related to Pseudocnella than to any other genus within the Colochirinae...

The genus Ajothrips was erected for two new species from India (Bhatti 1967), although subsequently a third Indian species was added (Bhatti 1997). All three species have remained known only from females, although Mound (2009) recorded the presence of sternal pore plates in unspecified males of this genus. The purpose of this note is to record the type species, A. karma, from China, and to describe the unknown male. The systematic position of the genus has a confusing history. Considered by Bhatti (1967) as related to Scirtothrips, it was subsequently excluded from the Scirtothrips genus-group (Masumoto & Okajima 2007)...

This review examines brain sites involved in sexual stimulation. New data on brain activation sites in individuals having erections concomitant with visual erotic stimulation was documented. The activation was chiefly at the midbrain around the cerebral peduncle, and in the pons centering on the tegmentum, they are indicated by blood oxygenation level dependent (BOLD) images captured by functional magnetic resonance imaging (fMRI). The cerebellum and inferior temporal lobe were activated more extensively in individuals viewing pornographic movie with a concomitant erection than those without...
