Penile erection is a neurovascular phenomenon that requires well coordinated and functional interaction between penile vascular and nervous systems. In order to provide a useful tool to examine pathologic changes in the erectile tissue, mainly focusing on penile neurovascular dysfunction, we established the technique to determine the differential distribution of endothelial cells, smooth muscle cells, pericytes, and nerve fibers in the mouse penis using immunohistochemical staining with three-dimensional reconstruction...

Scutellaria wuana, a new species discovered from a xeric valley in Muli County of Sichuan Province in southwest China, is described and illustrated. Morphologically, the new species shares similarities with S. mairei, but can be readily distinguished by a suite of morphological characters including a white-pubescent erect stem, conspicuous leaf petioles, and a yellow corolla with a trapeziform lower-middle lip lobe. The habitat and distribution of S. wuana are also distinctive. The position of the new species within Scutellaria is examined in a phylogenetic context using the nuclear ribosomal internal and external transcribed spacers...

Eutrema giganteum (Brassicaceae), a new species from Hengduan Mountains in Sichuan Province, southwest China, is described, and its relationships to the closely related E. yunnanense is discussed based on morphological, cytological, and molecular data. It is similar morphologically to E. yunnanense but is readily distinguished by having robust (vs. slender), erect (vs. decumbent), and branched (vs. mostly simple), and rather tall stems (60-110 cm vs. 20-60 cm); curved (vs. straight), smooth (vs. torulose), and shorter fruit (5-8 mm vs...

Michael J Sharkey, Eric Chapman
The Agathidini (Braconidae: Agathidinae) genera of Southeast Asia are revised based on a phylogenetic analysis of COI and 28S. Ten new genera are proposed, i.e., Agathigma, Asperagathis, Chimaeragathis, Cymagathis, Liragathis, Leuroagathis, Scabagathis, Trochantagathis, Xanthagathis, and Zosteragathis. An illustrated key to the Southeast Asian genera of this tribe is presented. Species from Thailand are keyed and described for all genera of Agathidini except Bassus and Zosteragathis which have too many species for this publication and will be dealt with separately...

In the present study, we critically revised the recently proposed classification of the subfamily Leishmaniinae Maslov et Lukeš in Jirků et al., 2012. Agreeing with erection of the genus Zelonia Shaw, Camargo et Teixeira in Espinosa et al., 2017 and the subgenus Mundinia Shaw, Camargo et Teixeira in Espinosa et al., 2017 within the genus Leishmania Ross, 1908, we argue that other changes are not well justified. We propose to: (i) raise Paraleishmania Cupolillo, Medina-Acosta, Noyes, Momen et Grimaldi, 2000 to generic rank; (ii) create a new genus Borovskyia gen...

BACKGROUND: Obstructive sleep apnea syndrome (OSAS) is a common disease that causes a different spectrum of life processes violations in the continuum of 'sleep-wakefulness'. OSAS in combination with age-specific hypogonadism as a systemic pathology requires certain interdisciplinary approaches involving both the correction of the obstruction, and testosterone therapy in men with hypogonadism. AIM: Assessment of the effect of combined use of CPAP (Continuous Positive Airway Pressure) and testosterone replacement therapy (transdermal form - Androgel) on indicators of polysomnography monitoring (PSG) with simultaneous study of erectile function and testosterone secretion...

Young Eun Kim, Hae Won Choi
The effect of stabilization of the degenerative segment on changes in the pattern of paraspinal muscle activity was investigated using a previously developed musculoskeletal model. Muscle activity change depending on L4-L5 segment stabilization with and without taking into account the presence of multifidus atrophy according to direct invasion of the back muscle during surgery (MADIBM) was analysed in erect standing and 20° flexed postures. For the stabilization of the degenerative segment, a fusion or non-fusion stabilization with a pedicle-based dynamic stabilization system (PBDS) was applied...

A 2D self-assembly of a C32H12 buckybowl on the Cu(111) surface has been studied by means of scanning tunnelling microscopy. Additional aromatic rings at the rim of the corannulene core cause the bowl-shaped molecule to stand on its edge. This adsorption mode allows distinct π-π and C-Hπ interactions between the convex bowl surfaces as well as between the hydrogen-terminated rim and the convex bowl faces.

Kamalesh K Gulia, Yukihiko Kayama, Yoshimasa Koyama
To understand the central mechanism of penile erections during rapid eye movement (REM) sleep and waking, single units were recorded from the septal area in un-anesthetized head-restrained rats simultaneous with erections. Erectile events were assessed by pressure in the bulb of the corpus spongiosum of the penis and bulbospongiosus-muscle activity. Of 143 recorded neurons, 36% showed increased activity (E-type) and 24% decreased activity (I-type) during different phases of erection in REM sleep, while 10% were E-type and 35% were I-type during erections in waking...

Seonghoe Jang, Hsing-Yi Li
Oryza sativa BRASSINOSTEROID UPREGULATED1 LIKE1 (OsBUL1) positively affects lamina inclination and grain size. OsBUL1 knock-out (osbul1) plants as well as transgenic rice with reduced level of OsBUL1 expression produce erect leaves and small grains. Here, we identified a putative downstream gene of OsBUL1, OsBUL1 DOWNSTREAM GENE1 (OsBDG1) encoding a small protein with short leucine-rich-repeats by cDNA microarray analyses in the lamina joint and panicles of wild-type and osbul1 plants. Transgenic rice plants with increased OsBDG1 expression exhibit increased leaf angle and grain size, which is similar to an OsBDG1 activation tagging line whereas double stranded RNA interference (dsRNAi) lines for OsBDG1 knock-down generate erect leaves with smaller grains...

The family Gymnophthalmidae contains nearly 235 species with a distribution range from southern Mexico to central Argentina as well as in the Antilles. Among gymnophthalmids, the genus Colobosaura is a member of the tribe Iphisini, and currently is considered monotypic (C. modesta). The diversity of the tribe was studied recently, with the erection of several new genera. In this work genetic and morphological data of specimens of Colobosaura recently collected in Paraguay were analyzed. Genetic (16S barcode) data indicate that these samples are not conspecific with C...

The ground beetle genus Bembidion is a highly diverse group of small predators with more than 1.200 described extant species. In contrast, only two representatives of Bembidion are known from the amber fossil record and their position within this mega-diverse genus is dubious. Here, we address the taxonomic position of these two extinct Bembidion species (B. succini Giebel, 1856 and B. christelae Ortuño & Arillo, 2010). Based on the insufficient description and the missing type specimen, B. succini, nomen dubium, cannot be assigned to the genus Bembidion and/or to the tribe Bembidiini with certainty...

Marie K Hörnig, Joachim T Haug, Carolin Haug
Mantodeans or praying mantises are flying insects and well known for their raptorial behaviour, mainly performed by their first pair of thoracic appendages. We describe here a new, exceptionally preserved specimen of the early mantodean Santanmantis axelrodi Grimaldi, 2003 from the famous 110 million years old Crato Formation, Brazil. The incomplete specimen preserves important morphological details, which were not known in this specific form before for this species or any other representative of Mantodea. Unlike in modern representatives or other fossil forms of Mantodea not only the first pair of thoracic appendages shows adaptations for predation...

Erectile function is a widely accepted indicator of systemic endothelial activity since from a clinical standpoint erectile dysfunction (ED) often precedes cardiovascular events. Recently it has been described a potential role for β3 adrenoceptor in cardiovascular diseases emphasizing a possible development of new drugs. β3 adrenoceptor stimulation relaxes human corpus cavernosum (HCC) strips in cyclic guanosine monophosphate (cGMP)-dependent and endothelium/nitric oxide (NO)-independent manner. Hydrogen sulfide (H2S), along with NO, is another gaseous molecule involved in cardiovascular system and as a consequence also in penile erection...

Priapism is a state of prolonged and unwanted erection without sexual stimulation or desire. Priapism may occur with a variety of diseases or as a side effect of medication. Immediate diagnosis and treatment is essential, as ischemia of cavernous tissues results in erectile dysfunction. Described in the present report is a 12-year-old male with priapism associated with the addition of risperidone to methylphenidate monotherapy. Priapism decreased and disappeared following discontinuation of drug therapy and implementation of cavernous drainage...
