To test the usefulness of a cellulose acetate polymer(CAP) solution for brain arteriovenous malformations (AVMs), we analyzed the clinical and histological results of patients with AVMs embolized using CAP solution. We reviewed the cases of six patients with cerebral AVMs treated by embolization prior to surgical resection. We used two types of CAP solutions, CAP-M and CAP-L, which are mixtures of 250 mg of solid CAP and 1800 or 2250 mg of bismuth trioxide dissolved in 5.5 or 7.0 ml of dimethyl sulfoxide, respectively. All patients underwent surgical resection 1 to 37 days after the embolization procedure. Resected specimens were fixed in formalin and stained for light microscopic examination. Eighteen feeding vessels were embolized. The reduction rate of the nidus volume was between 20% and nearly 100%. Mild ischemic deficits occurred in one patients but there were no hemorrhagic complications related to the embolization procedures. All AVMs were completely resected by surgery. Direct inspection at surgery revealed that there was no apparent swelling or hematomas in the normal brain areas adjacent to the nidus, and the AVMs were soft enough to be easily retracted. The histological examinations disclosed no or mild inflammatory reactions within two weeks after embolization. The internal elastic lamina was preserved in every case. Recanalization of embolized vessels was not observed until 37 days after embolization. CAP solution is a safe and useful embolic agent for brain AVMs. Further study is needed to resolve the issue of recanalization.

We assessed the long-term follow-up results of platinum coil embolization and aneurysmography (ARG) with endovascular surgery for giant aneurysms. 24 cases of giant aneurysms were treated over a period of seven years. In the present study, the 16 of these for which surgical dipping was impossible so that only endovascular surgery was employed were investigated in detail. In 10 cases the cavernous sinus area was involved, in two each the tip of the basilar artery, and the bifurcation of the ophthalmic artery, and in one each the extracranial internal carotid and the vertebral artery. Since conventional angiography did not allow the position and size of the neck of 10 cavernous sinus aneurysms to be identified, making treatment decisions difficult, we applied the ARG developed by the senior author. Prior to treatment, balloon test occlusion of the parent arteries was performed. In all 10 cavernous sinus cases, ARG successfully revealed the morphology of the aneurysm. A small neck was diagnosed for seven of the aneurysms of the cavernous sinus and all those located at the basilar and ophthalmic arteries, making a total of 11, and for these endosaccular embolization was carried out. In the other 5 cases, proximal occlusion using Gold valve balloons was performed. Under ARG, embolization of the aneurysms could be safely accomplished with platinum coils, without dislocation of the coils into the parent arteries in all cases. In four out of 10 cases, re-opening of the aneurysms occurred after 2 months or longer, so that re-embolization was required. Regarding complications, transient monoparesis of the upper extremity was encountered in one case. After angiographic and MRA follow-up of 1–36 months (average, 13.8 months), 4 of 10 cases demonstrated complete occlusion, and 5 displayed an 80–90% reduction in blood flow. In only one case, involving a basilar tip aneurysm, was the treatment unsuccessful in preventing eventual rupture and death. In cases where the morphology of the aneurysm is unclear, ARG can be considered indispensable for determining the treatment modality and safe performance of localized embolization of the neck by endovascular surgery. However, since coils used for embolization of giant aneurysms may move or become compacted, re-opening can occur so that applications may be limited, especially with terminal type lesions with intraluminal thrombus, and the necessity for long-term follow-up must be emphasized.

Transvenous embolization has been recommended recently as the primary treatment for symptomatic cavernous dural arteriovenous fistula(dural AVF). We present a case of sigmoid sinus dural AVF which developed after transvenous embolization of cavernous dural AVF A 43-year-old man was admitted to our hospital because of left conjunctival chemosis, exophthalmus and abducens nerve palsy. Cerebral angiograms showed left cavernous dural AVF fed by the bilateral internal and external carotid arteries and draining into the enlarged left superior ophthalmic vein. Transfemoral approach in the cavernous sinus via inferior petrosal sinus (IPS) was difficult because of the occlusive change of IPS. Then, direct canulation of the left superior ophthalmic vein and transvenous embolization using interlocking detachable coils (IDC) were performed. Dural AVF and clinical symptoms were disappeard rapidly after embolization. Six months later, follow-up cerebral angiograms showed development of a dural AVF in the left sigmoid sinus. The pathogenesis of dural AVF remains unclear. We suggest that injury to the sinus wall during endovascular procedures may have provoked the development of dural AVF in our case. Clinical and angiographical follow-up are important.

Published: January 2017

We describe 19 (16.0%) multiple vascular malformations (AVMs) in 119 spinal cord arteriovenous malformations (SCAVMs). The associated lesions were eight vertebral vascular malformations, two cutaneous, four limbs, four radicular AVMs, three bifocal SCAVMs; one patient had a bifocal cord lesion associated with vertebral and limb localisations. Various syndromic associations were seen: nine Cobb, two Klippel-Trenaunay-Weber, one Parkes Weber. An additional subgroup of unclassified associations is constituted by seven cases with bifocal intradural uni or multimetamerk lesions. In our SCAVMs series, the incidence of multiple vascular lesions is high, in particular multifocal intradural malformations. Metameric distribution is the most frequent type of multiplicity. Identification of the myelomeric level involved in SCAVM allows segmental link between various lesions of mesodermal or neural crest origin to be discussed.

Published: January 2017

This report describes three years of clinical experience with a new set of devices aimed at improving functional MRI of speech areas. They provide a valuable tool for pre-operative definition of hemispheric localization and spatial extension of these areas, especially in left-handed persons. The fibre-optic device described here transmits stimuli for cognitive tasks to patients undergoing MR investigations. Cognitive tasks elicit a defined brain activity lasting for several minutes. The resultant metabolic changes are detectable by functional MRI. The software (FIT ware) applied to process raw data allows semi-automated segmentation of the brain so as to obtain 3D images. Furthermore it allows the superposition of functional data. The effectiveness of the equipment was assessed on the basis of data from 140 fMRI studies. Intra-operative verification in eight patients with tumours located in the speech areas showed that the new set-up identified the speech-dominant side in each case and located speech areas in accordance with electrophysiological procedures.

Published: January 2017

Although no consensus yet exists on the ideal patient characteristics, materials, and indications for carotid angioplasty, it is clear that this procedure which is increasing in popularity will continue to do so. Until such time as the procedure is routinely approved (there are still barriers to insurance coverage for these procedures in the United States), we are highly selective in our application of carotid angioplasty. So far our experience is limited to approximately 40 patients with no major complications and no strokes. However, patient characteristics, operator experience, and patient selection play large roles in the outcomes of these procedures. The current status of carotid angioplasty and stenting wilt be discussed as well as the potential complications and their treatment.

Published: January 2017

We describe follow-up clinical and angiographical results in patients with unruptured cerebral aneurysms treated with IDC or GDC. In 28 patients who underwent intra-aneurysmal occlusion for unruptured aneurysms, there were no permanent neurological deficits in the periprocedural period, while three transient neurological deficits were observed. On the angiograms obtained immediately after the procedure, complete aneurysmal occlusion was achieved in three patients (10.7%), a small neck remnant was detected in two cases (7.1%), a body filling in 12 cases (42.9%) and both of them were detected in 11 patients (39.3%). On the follow up angiograms (median angiographical follow-up period 15.6 months), 46.4% of incompletely obliterated aneurysms showed aneurysmal recanalization, and a incompletely embolized aneurysm ruptured 15 months after initial embolization. Detachable platinum coil embolization is a safe treatment for unruptured aneurysms with a lower incidence of peri-procedural morbidity, wheareas follow-up results are less satisfactory in cases involving incompletely obliterated lesions. With this limitation in mind, patients need to be very carefully chosen for GDC embolization and strict follow-up angiography is mandatory when a complete embolization is not achieved.
Design Quality in the Context of Healthcare Environments: A Scoping Review
Authors: Anåker Anna , Heylighen Ann , Nordin Susanna , Elf Marie 
Published: January 2017

Objective: We explored the concept of design quality in relation to healthcare environments. In addition, we present a taxonomy that illustrates the wide range of terms used in connection with design quality in healthcare. Background: High-quality physical environments can promote health and well-being. Developments in healthcare technology and methodology put high demands on the design quality of care environments, coupled with increasing expectations and demands from patients and staff that care environments be person centered, welcoming, and accessible while also supporting privacy and security. In addition, there are demands that decisions about the design of healthcare architecture be based on the best available information from credible research and the evaluation of existing building projects. Method: The basic principles of Arksey and O’Malley’s model of scoping review design were used. Data were derived from literature searches in scientific databases. A total of 18 articles and books were found that referred to design quality in a healthcare context. Results: Design quality of physical healthcare environments involves three different themes: (i) environmental sustainability and ecological values, (ii) social and cultural interactions and values, and (iii) resilience of the engineering and building construction. Design quality was clarified herein with a definition. Conclusions: Awareness of what is considered design quality in relation to healthcare architecture could help to design healthcare environments based on evidence. To operationalize the concept, its definition must be clear and explicit and able to meet the complex needs of the stakeholders in a healthcare context, including patients, staff, and significant others.
The Cricoid Force Necessary to Occlude the Esophageal Entrance: Is There a Gender Difference?

Published: January 2017

BACKGROUND:
We tested the hypothesis whether gender differences exist in the applied cricoid force necessary to prevent regurgitation. Real-time visual and dynamic means were used to assess the effectiveness of different applied cricoid forces in occluding the esophageal entrance in men (group 1) and in women (group 2).

METHODS:
In anesthetized and paralyzed patients, the glottis and esophageal entrance were visualized with a Glidescope video laryngoscope. Trained operators performed cricoid pressure (CP) and gastric tube insertion trials. Successful gastric tube insertion in the presence of CP was considered ineffective CP, whereas unsuccessful insertion was considered effective CP. The applied cricoid forces were measured with a novel instrument, the cricometer. The first patient in each group received 20 N. The applied cricoid force in successive patients was determined by the response of the previous patient within the same group, using the up-and-down sequential allocation technique.

RESULTS:
In the 30 men and 30 women who qualified for the study, the median cricoid force (cricoid force = 50) that occluded the esophageal entrance was 30.8 N (95% confidence interval = 28.15–33.5) in men, and 18.7 N in women (95% confidence interval = 17.1–20.3; P < .0001). Patency of the esophageal entrance was observed when CP was not applied and when inadequate forces that allowed successful esophageal cannulation were used.

CONCLUSIONS:
The current study provides evidence that the median force necessary to occlude the esophageal entrance to prevent regurgitation is less in women compared with men. Applying the appropriate cricoid force in women should also decrease airway-related problems that tend to occur with the use of excessive forces. The findings of the current study may only be applicable to patients with normal body habitus.
Afrocasia kahlertiana gen. et sp. nov., a new tropical member of Araceae from Late Cretaceous strata of northern Gondwana (Baris, Egypt)
Authors: Coiffard Clément , Mohr Barbara A.R. 
Published: January 2017

AbstractFossil plant material was collected during the 1980s in Egypt and preliminarily described as a putative member of Araceae. Reexamination of the collections led to the discovery of new specimens and preparation of the material provided new characters confirming the araceous affinities of the fossil. The morphology of these leaves, especially the venation pattern of several vein orders, has been compared with leaves of fossil and extant monocot angiosperms, especially Araceae. The colocasioid secondary venation and the marginal venation pattern of the fossil are most similar to living Araceae, especially Aroideae. A new genus and species, Afrocasia kahlertiana gen. et sp. nov., were erected to accommodate these results. The physiognomy of Afrocasia kahlertiana supports the hypothesis of a humid and shady environment and indicates that Araceae have inhabited forest understory for at least 70 million years. Furthermore, its occurrence in Africa indicates that Araceae probably suffered stronger extinction on this continent.

Abstract. Setianto J, Zain B, Sutriyono, Prakoso H. 2017. Domestication of red jungle fowl: A case study of the red jungle fowl chicks procurement by the communities in Central Bengkulu, Indonesia. Biodiversitas 18: 183-189. The existence of the red jungle fowl is increasingly pressured by habitat destruction, illegal hunting, and predatorsâ€™ consumption which may result in an extinction. Conservation of the red jungle fowl had institutionally not been carried out both by the government and private institutions. However, the communities in Central Bengkulu District had done a domestication of the red jungle fowl. Until now, the conservation of the red jungle fowl in a community was not much studied. This study aimed to identify information about the origin of the red jungle fowl chicks, the origin of purchase of chicks, the equipment used for hunting and the chicks purity. Respondents selection was conducted by using a snowball sampling method. The data were obtained by using a combination of in-depth interviews, questionnaires, and a direct observation. The results showed that 38% respondents obtained the chicks from hunting, 40% from buying, 2% from hunting and buying, 6% from buying and conferral, and 14% from conferral. From respondents who did the chicks buying, 4.2% respondents bought the red jungle fowl from the traditional markets, 91.6% bought from hunters, and 4.2% bought from the chicks. Hunting activities were undertaken by 40% respondents, while 60% did not practice hunting activities. From respondents who did the hunting activities, 10% used a net, 30% used racit equipment and 60% used a combination of net and racit. Chicks obtained by respondents, 46% of the red jungle fowl and 54% of the offspring of the red jungle fowl. The red jungle fowl chicks were obtained from nature by hunting in the forests or plantations and from the surrounding communities, either by purchase or conferral.

Study of glycyrrhizic acid contents from Glycyrrhiza glabra populations in Iran and their relation with environmental factors. Biodiversitas 18: 212-220. Glycyrrhizin (glycyrrhizic acid) is an important chemical composition of licorice (Glycyrrhiza glabra L.) from which is 50 times sweeter than sucrose. In this study, the amount of glycyrrhizic acid was determined in populations collected from 11 different locations in Iran (NW to NE) by HPLC method from two varieties of this species; Glycyrrhiza glabra varieties glabra and glandulifera. Our results showed the highest content of glycyrrhizic acid was from Naghadeh (NAQ, NW Iran) population for G. glabra var. glandulifera and Azadshahr population (AZD, NW Iran ) for G. glabra var. glabra. Lowest amounts of glycyrrhizic acid were detected in Jajrood (JAD, N Iran) population for G. glabra var. glandulifera and Hashtrud (HSD, N Iran) population for G. glabra var. glabra. Significant correlations were observed between the amount of glycyrrhizic acid and some morphometric parameters, soil and environmental factors. The amount of glycyrrhizic acid showed positive correlation with phosphorous (P â‰¤ 0.05 and R2 =0.155) and negative correlation with pH (P â‰¤ 0.01 and R2 =0.348) and calcium carbonate (P â‰¤ 0.01 and R2 =0.507). Higher temperature resulted in increasing the amount of glycyrrhizic acid. Based on morphometrical data, the plants with thinner rhizomes would have more glycyrrhizic acid. Our results also showed that glycyrrhizic acid content was not related to taxonomic classification of this species.

Abstract. Syahid SF, Heryanto R.2017. Short Communication: Morpho-agronomic characteristics of twelve accessions of white turmeric (Curcuma zedoaria) germplasm. Biodiversitas 18: 269-274.White turmeric (Curcuma zedoaria Rosc.) is a potential medicinal plant belong to the family Zingiberaceae. This plant has a good market because of its high demand as raw material for herbal medicine, such as to cure cancer. A germplasm collection of white turmeric collected from different areas of Indonesia is available at Cicurug Research Station of Sukabumi, West Java, Indonesia. Information on characteristics of the accessions, however, are not available yet. This study aimed to determine morphological characters, growth, and yield of 12 accessions of white turmeric. The research was conducted at the Cicurug Research Station from January 2014 to March 2015. Rhizome section of each accession was grown in a 2.5 m x 3.5 m plot at 50 cm x 50 cm plant spacing. The experiment was arranged in a randomized complete block design with three replications. Parameters observed were morphological characters (type of stem, leaf tip, leaf base, leaf shape, stem color, blade color), growth (number of tillers, plant height, number of leaf/stem, leaf length, leaf width, leaf thickness) and yield (rhizome weight, rhizome length, rhizome width, and rhizome thickness) respectively. The results showed that morphological characters, growth, and yields of the 12 accessions observed were varied. All of the characters observed could be evaluated further to determine the important traits.

Comics art and urban cultural studies method through Chris Ware’s Building Stories (2012)
Authors: Fraser Benjamin 
Published: January 2017

Abstract
This concise editorial explores the current disciplinary gaps between geographical and humanities analyses of cultural production through consideration of a specific example. American comics artist Chris Ware’s Building Stories, considered a masterpiece of comics art, has attracted attention from both humanists and geographers on account of its urban theme and its intriguing architectural form. This interest raises two sets of questions for a proper cultural studies analysis. First, to what degree are humanities scholars approaching the work without attending to geographical issues of space/place that inevitably figure into its architectural form? And second, to what degree are geographers approaching the work without addressing the humanities issues of artistry and representation that figure into its comics form? Surveying the criticism on this work may provide some initial answers to these questions and in the process speak to larger issues of interdisciplinary research in urban cultural studies.
Not a fantasy city: Composition, fotogènia and the reconquesta del real in the theatrical and cinematic land/lang-scapes of Barcelona
Authors: Comparone Loredana 
Published: January 2017

Abstract
Focusing on the return of the real in contemporary art, the article examines how Lluïsa Cunillé’s play, Barcelona, mapa d’ombres (2004), and Ventura Pons’s 2007 film, Barcelona (un mapa), apprehend the urban landscape as ‘composition’, and how they bring into dialectical relation modes of apprehension and representation traditionally perceived and pitched as ideologically opposed or mutually exclusive. Like modernist art (cubism), these works beget oppositional and counter-hegemonic ways of imagining the urban landscape within what remains ‘the ongoing dominance of the “hegemony” of capital’. As a mode of analysis, composition does not only interrupt the ‘delirious equivalency’ of late capitalist abstraction, but it also becomes a deliberate intervention in self-fashioning and city-making endowed with a political, if not also an ethical, component.
