Ectoparasites of rabbits and hares in Manitoba, Canada, with observations on age-specific dispersal in Haemodipsus setoni (Phthiraptera: Anoplura: Polyplacidae)
Authors: Galloway Terry D.
Published: May 2012

During 1994–2008, 58 adult and 195 juvenile eastern cottontail rabbits (Sylvilagus floridanus (Allen)), one adult and 23 juvenile snowshoe hares (Lepus americanus Erxleben), and eight adult white-tailed jackrabbits (Lepus townsendii Bachman) (Mammalia: Leporidae) were examined for ectoparasites. The most abundant ectoparasite on cottontails was the sucking louse, Haemodipsus setoni Ewing (Phthiraptera; Polyplacidae), recorded from this host for the first time. Infestations in adult and juvenile cottontails were highly aggregated, k = 0.136 and 0.153, respectively. Prevalence of infestation in adult cottontails was 70.6%, with a mean intensity of 5614.1 (range: 1–166 249); 10 adults had more than 1000 lice. In juvenile cottontails, prevalence was 34.8% and mean intensity was 6.2 (range: 1–87). On adult cottontails, 73.4% of the total lice were nymphs, while on juvenile cottontails only 11.6% were nymphs. It appears that dispersal from parents to offspring is overwhelmingly achieved by adult lice. Seventeen adult cottontails were infested with the tick, Haemaphysalis leporispalustris (Packard) (Acari: Ixodidae). No fleas specific to rabbits were collected but small numbers of the rodent fleas Monopsyllus vison (Baker), Orchopeas caedens (Jordan), and Aetheca wagneri (Baker) (Siphonaptera: Ceratophyllidae) were recorded. Only one snowshoe hare was infested with H. setoni and three were infested with H. leporispalustris; no fleas were found on snowshoe hares. Two white-tailed jackrabbits were infested with H. leporispalustris; one carried Pulex irritans Linnaeus (Siphonaptera: Pulicidae), and none carried lice.

Authors: Maio Paula , Carvalho Rodrigo , Amaro Cristina , Santos Raquel , Cardoso Jorge
Published: May 2012

Methylmethacrylate was first reported in 1941 as a cause of contact dermatitis. Since then, occupational contact allergies to acrylates in dentistry, orthopedic surgery, printing industry and industry have been reported, but few reports are found in the literature as a consequence of the contact with sculptured artificial acrylic nails which are increasingly popular. We describe here 3 patients with contact allergy to acrylates in artificial sculptured nails. Patch tests were performed with the Portuguese baseline series of contact allergens and an extended series of acrylates were applied. In particular, we tested three female patients with allergic contact dermatitis from sculptured acrylic nails. Two of these patients were both customers and also technical nail beauticians. Two patients developed periungual eczema; one presented only with face and eyelid dermatitis had no other lesions. The tests showed positive reaction to 2-hydroxyethylmethacrylate (2-HEMA) and 2-hydroxypropylmethacrylate (2-HPMA) in all the three patients. Our cases demonstrate the variety of clinical presentations of allergic contact dermatitis from acrylic sculptured nails. They show the need to warn patients of persistent and sometimes permanent side effects of these products. They also emphasize the importance of cosmetic ingredient labeling.

What is it like to be a god? A philosophical clarification of instances of divine suffering in the Psalter
Authors: Gericke Jaco W.
Published: May 2012

There are times when one would like to hang the whole human race, and finish the farce. (Mark Twain)In philosophy of religion, there is a long history of belief that divine reality is immutable, although this has changed recently. In this article, the author takes a closer look at what some texts in the Psalms assumed about what it feels like for a god to suffer mentally. By paying attention to what is presupposed in language about negative divine emotions, the nature of mental anguish in the life of a deity is elucidated from examples in the text in which Yhwh is said to have states of mind involving anger, hate, compassion, jealousy and grief.

Authors: Micheli Douglas Côbo , Fernandes Paulo Cesar , Cruvinel João Celso Garcia , Destro Nomelini Isabela , Murta Eddie Fernando Candido , Tavares-Murta Beatriz Martins
Published: May 2012

Aim

To verify if patients with cervical neoplasia produce mediators that reduce leukocyte function.

Methods

Control neutrophils incubated with normal serum or serum from pre-invasive or invasive neoplasia patients were assayed for chemotaxis. Mediators were assayed in serum and in leukocyte supernatants. Experiments were also performed in random patients after surgery.

Results

Neutrophils incubated with patient sera, but not normal sera, failed to migrate towards the chemoattractants. In invasive neoplasia compared to controls, IL-6 and IL-8, and IL-10 and TNF-α were elevated in serum and in neutrophil supernatants, respectively. Nitrite levels were elevated in mononuclear cell supernatants from patients than controls. After surgery, serum cytokine levels were reduced, mainly in pre-invasive patients. Neutrophils treated with serum from pre-invasive patients undergone surgery had restored migration.

Conclusion

Patients with cervical neoplasia produce mediators, predominantly induced by tumor cells, able to impair the inflammatory response at very early stages of disease.
The bandwagon effect on participation in and use of a social networking site
Authors: Fu W. Wayne , Teo Jaelen , Seng Seraphina
Published: May 2012

This study examined the bandwagon effect on participation in and use of one particular SNS — Facebook — using a Singapore–based sample of active Internet users. Building on theories addressing the social mechanisms of interactive or communicative technologies, we tested the postulation that the decision of individuals to participate in Facebook would be linked to their perceptions of how widely Facebook had been diffused either at large or among their off–line contacts. Regression analyses confirm this bandwagon tendency in Facebook participation. Moreover, multiple SNS users tended to use Facebook more than all other SNSs if they perceived that it penetrated their off–line contacts more widely. The results suggest that Internet users engage in SNSs to forge personal online networks in ways complying with real–world group proximity and their perception of the prevalence of adoption rather than making random or amorphous choices.
A market for unbiased private data: Paying individuals according to their privacy attitudes
Authors: Aperjis Christina , Huberman Bernardo A.
Published: May 2012

Since there is, in principle, no reason why third parties should not pay individuals for the use of their data, we introduce a realistic market that would allow these payments to be made while taking into account the privacy attitude of the participants. And since it is usually important to use unbiased samples to obtain credible statistical results, we examine the properties that such a market should have and suggest a mechanism that compensates those individuals that participate according to their risk attitudes. Equally important, we show that this mechanism also benefits buyers, as they pay less for the data than they would if they compensated all individuals with the same maximum fee that the most concerned ones expect.

Authors: Canessa Pier Aldo , Manta Carmen , Ferro Paola , Franceschini Maria Cristiana , Sivori Massimiliano , Fontana Vincenzo , Fedeli Franco , Pistillo Maria Pia , Roncella Silvio
Published: May 2012

Background

human mammaglobin (hMAM) expression has been reported in pleural effusions (PE). The aim of this study was to assess the clinical relevance of hMAM mRNA in PE from patients who underwent thoracoscopy.

Material and methods

A total of 288 patients with PE were studied, 155 of which were diagnosed with malignant and 133 with non-malignant diseases by thoracoscopy. Cells from PE were analyzed by nested hMAM RT-PCR. Statistical analyses were performed to evaluate the diagnostic performance parameters (DPP), the association between hMAM expression and benign or malignant status and the relative risk of cancer for patients with negative thoracoscopy showing hMAM positivity.

Results

hMAM mRNA was found in 68/288 (23.6%) PE samples of which 51 were from the 155 patients diagnosed with malignant diseases and 17 were from the 133 patients diagnosed with non-malignant diseases. A significant correlation between hMAM expression and malignancy was found (OR=3.04) and the DPP were as follows: sensitivity=32.9%, specificity=87.2%, accuracy=58.0%, positive predictive value=75.0% and negative predictive value=52.7%. Among the patients with negative thoracoscopy (n=133), 5/17 (29.4%) hMAM-positive patients had or developed a tumor during the 18-month follow up period, as compared to 10/116 (8.6%) hMAM-negative patients (relative risk of 4.6 for developing a malignancy).

Conclusion

These findings suggest a possible application of hMAM RT-PCR detection in PE as to identify a false-negative thoracoscopy in non-specific pleuritis.

Authors: Donnelly Tam Truong , Al Khater Al-Hareth , Al-Bader Salha Bujassoum , Al Kuwari Mohamed Ghaith , Al-Meer Nabila , Malik Mariam , Singh Rajvir , Chaudhry Sofia , Dorri Roqaia Ahmad
Published: May 2012

Background: Breast cancer is the most common cancer among women in the State of Qatar, and the incidence rate is rising. Previous findings indicate women in Qatar are often diagnosed with breast cancer at advanced stages and their participation rates in screening activities are low.

Purpose: To investigate within the State of Qatar Arabic women’s knowledge regarding breast cancer and breast cancer screening (BCS) methods and their participation rates in BCS. This paper reports on the results of a cross-sectional survey.

Methods: A quantitative, cross-sectional interview survey was conducted with 1,063 Arabic women (Qatari citizens and non-Qatari Arabic-speaking residents), 35 years of age or older, from March 2011 to July 2011.

Results: Of the 1,063 women interviewed (87.5% response rate), 90.7% were aware of breast cancer; 7.6% were assessed with having basic knowledge of BCS, 28.9% were aware of breast self-examination (BSE), 41.8% were aware of clinical breast exams (CBE), and 26.9% were aware of mammograms. Of the women interviewed, 13.8% performed BSE monthly, 31.3% had a CBE once a year or once every two years, and 26.9% of women 40 years of age or older had a mammogram once a year or once every two years. Participation rates in BCS activities were significantly related to awareness and knowledge of BCS, education levels, and receiving information about breast cancer, self-examination or mammography from any of a variety of sources, particularly physicians.

Conclusions: Study results demonstrate that despite the existent breast cancer screening recommendations, less than one-third of Arabic women living in Qatar participate in BCS activities. Public health campaigns encouraging more proactive roles for health care professionals regarding awareness and knowledge of breast cancer, BCS, and the benefits of early detection of breast cancer will help increase screening rates and reduce mortality rates among Arabic women living in the State of Qatar.
A Comparison of Antioxidant Properties in Organic and Conventional Blueberries
Authors: Gupta-Elera Gaytri , Garrett Andrew , Martinez Andres , Kraus Ryan D. , Robison Richard , O’Neill Kim
Published: May 2012

Vacciniumcyanococcus, most commonly known as blueberry, is a fruit native to North America that is known for its unique taste and high antioxidant content. The skin, seed and juice of both organically and conventionally grown blueberry extract were analyzed for antioxidant content using both the Hydrophilic and Lipophilic Oxygen Radical Absorbance Capacity (ORAC) assays. Results from the Hydrophilic ORAC test showed that conventionally grown blueberries had a higher antioxidant capacity across all samples, while the Lipophilic ORAC assay showed that the antioxidant concentration of organically cultivated blueberry juice was highest, but conventionally grown blueberry seed and skin extract showed higher antioxidant content. The vitamin C content of both conventional and organic blueberries was analyzed using High Performance Liquid Chromatography (HPLC), where the organic blueberries showed a higher vitamin C concentration. In general, both organic and conventional blueberries are rich in antioxidants, and therefore, possess potential health benefits that require further study.
Non-wood Forest Products Based on Extractives - A New Opportunity for the Canadian Forest Industry Part 1: Hardwood Forest Species
Authors: Royer Mariana , Houde Robert , Viano Yannick , Stevanovic Tatjana
Published: May 2012

Forest resources are among the most important of Canada (in the case of Québec, nearly 90% of the territory). Innovation represents an essential challenge for the Canadian forest industry, which is presently undergoing major changes towards finding new solutions for recovery. The processing of forest biomass has become increasingly relevant along with the popular concept of biorefineries. This concept should include the development of novel technologies based on forest extractives. Bioactive molecules are readily available through eco-friendly extraction processes using various types of forest residues including barks which are generated in significant quantities by the industry. This literature review offers a glimpse into the hardwood boreal forest with a particular focus on industrial species. We are adopting an ethno-pharmacological approach prior to presenting existing data on bioactive molecules from various sources, along with results from our own laboratory. In conclusion, this paper clearly demonstrates the need for further research on bioactive molecules from Canadian forest species since there remains an important lack of reliable data.
Health, Culture, and Power
Authors: Aldoory Linda
Published: May 2012

Only limited research has been published about women as an audience of health messages in the media. Furthermore, most of the well‐known health communication theories have not effectively addressed the sociocultural and political environments that construct the medical/health industry and the media, which impact the everyday lives of women and their decision‐making in the area of health. This chapter offers a comprehensive overview of the research conducted on women audiences of health messages in the media. The chapter then critiques this body of knowledge on account of its weak theoretical utility/development potential for women's health decision‐making and empowerment. After review and critique, empirical examples are provided from research and related studies on women's media consumption, in order to reconstruct theoretical arguments that reflect women's everyday lives and contribute to women's decision‐making about their health. The chapter concludes with an agenda for future research in the area of women as audiences of health communication.
The Future of Game Studies
Authors: Consalvo Mia
Published: May 2012

The digital game industry has been evolving at a phenomenal rate and can no longer consider console games and the Western market as its primary areas of focus. Social games, casual games, virtual worlds, indie games, and online games all expand the boundaries of what count as games. In addition, markets such as China and Korea and game development companies in Southeast Asia and Eastern Europe are challenging the dominance of Western and Japanese firms. How is game studies responding to such changes? Likewise, how is the field coalescing, now that there are dedicated journals, book series, conferences, and academic programs spread around the globe? In this chapter, Mia Consalvo explores how game studies has moved from “indie startup” to mid‐career in its own growth trajectory of the last decade. She surveys how scholarship has evolved, what approaches have intentionally (or not) become dominant, and what views have emerged about the “proper” way to do game studies research. The chapter concludes with challenges to the field, pointing to areas that have been overlooked, problems that remain, and the continuing question of the possibilities and pitfalls of making game studies research useful for popular and industry audiences.
Non‐fragile robust stabilization and H ∞  control for uncertain stochastic time delay systems with Markovian jump parameters and nonlinear disturbances
Authors: Senthilkumar T. , Balasubramaniam P.
Published: May 2012

This paper considers the problems of non‐fragile robust stabilization and H ∞  control for uncertain stochastic time delay systems with Markovian jump parameters and nonlinear disturbances. The parameter uncertainties are assumed to be time‐varying norm bounded appearing in both state and input matrices. The purpose of the non‐fragile robust stabilization problem is to design a memoryless non‐fragile state feedback controller such that the closed‐loop system is robustly stochastically stable for all admissible uncertainties in both the system and controller. In addition to the aforementioned requirement, a prescribed H ∞  performance level is required to be achieved for the non‐fragile robust H ∞  control problem. With the use of the Lyapunov–Krasovskii functional method and free‐weighting matrices, delay‐dependent sufficient conditions for the solvability of these problems are obtained in terms of LMI. Finally, a numerical example is provided to demonstrate the effectiveness of the proposed approach. Copyright © 2012 John Wiley & Sons, Ltd.
Activity patterns in New Kingdom Nubia: An examination of entheseal remodeling and osteoarthritis at Tombos
Authors: Schrader Sarah A.
Published: May 2012

The effects of Egyptian imperial expansion into Nubia during the New Kingdom Period (1,550–1,069 BC) have been debated. Here, the impacts of the Egyptian Empire are investigated through an examination of osteological indicators of activity at the archaeological site of Tombos. Entheseal changes to fibrocartilaginous attachment sites and osteoarthritis are examined to infer what types of physical activities this colonial town was engaging in. Many of the skeletal remains at Tombos were comingled due to looting in antiquity; undisturbed burials are presented as a subsample of the population (n = 28) in which age, sex, and body size can be considered. The total sample (n = 85) is then analyzed to better understand overall levels of activity. A number of Nile River Valley bioarchaeological samples are used as points of comparison to the Tombos population. Results indicate that the inhabitants of Tombos had relatively low entheseal remodeling scores; this is highlighted when Tombos is juxtaposed with comparative samples, particularly in men. Furthermore, osteoarthritis, as assessed by eburnation, was also markedly infrequent at Tombos. Collectively, these results indicate a relatively low level of activity and support the hypothesis that Tombos may have served as an administrative center.

Authors: Weidlich Tomáš , Dušek Libor , Vystrčilová Barbora , Eisner Aleš , Švec Petr , Růžička Aleš
Published: May 2012

The potential catalytic activity of selected C,N‐chelated organotin(IV) compounds (e.g. halides and trifluoroacetates) for derivatization of both dimethyl carbonate (DMC) and diethyl carbonate (DEC) was investigated. Some tri‐, di‐ and monoorganotin(IV) species (LCN(n‐Bu)2SnCl (1), LCN(n‐Bu)2SnCl.HCl (1a), LCN(n‐Bu)2SnI (2), LCNPh2SnCl (3), LCNPh2SnI (4), LCN(n‐Bu)SnCl2 (5), LCNSnBr3 (6) and [LCNSn(OC(O)CF3)]2(μ‐O)(μ‐OC(O)CF3)2 (7)) bearing the LCN moiety (LCN = 2‐(N,N‐dimethylaminomethyl)phenyl‐) were assessed as catalysts for reactions of both DMC and DEC with various substituted anilines. The catalytic activities of 4 and 7 for derivatization of DMC with p‐substituted phenols were studied for comparison with the standard base K2CO3/Silcarbon K835 catalyst (catalyst 8). The composition of resulting reaction mixtures was monitored by multinuclear NMR spectroscopy, GC and GC‐MS techniques. In general, catalysts 1, 3 and 7 exhibited the highest catalytic activity for all reactions studied, while some of them yielded selectively carbonates, carbamates, lactam or substituted urea.

Cell voltage and chlorine current efficiency of aqueous HCl electrolysis: artificial neural network modeling
Authors: Abbasian M. , Sattari A.
Published: May 2012

Artificial neural network (ANN) models were developed for the prediction of cell voltage and chlorine current efficiency (ChCE) of HCl electrolysis process. Results of 53 distinct experiments were used for ANN simulations; from which 40 data (75%) were used to train the networks and 13 data (25%) were used to test them. The predicted cell voltages and chlorine current efficiencies were found to be very close to the measured values with root mean square error of 0.087 and 1.726, R2 of 0.897 and 0.903, T values of 0.885 and 0.887 and average deviations of only 3.45 and 7.18%, respectively. Sensitivity analysis of the developed models showed that among five operating factors, the current density and the anolyte concentration had the highest and the least contributions to the cell voltage, respectively. On the other hand, the ChCE was mostly affected by the oxygen flow rate; meanwhile, the anolyte flow rate had the lowest effect on the ChCE.

Preparation and characterization of nanoporous polysulfone membranes with high hydrophilic property using variation in CBT and addition of tetronic‐1107 surfactant
Authors: Mousavi Seyed Mahmoud , Saljoughi Ehsan , Sheikhi‐Kouhsar Mohammad Reza
Published: May 2012

Asymmetric polysulfone (PSF) membranes were prepared from PSF, Tetronic‐1107, and 1‐methyl‐2‐pyrrolidone (NMP) via immersion precipitation. Pure water was used as the gelation media. The effects of coagulation bath temperature (CBT) (0 and 25°C), and addition of Tetronic‐1107 on the morphology, wettability, and pure water permeation flux (PWF) of the prepared membranes were studied by scanning electron microscopy (SEM), atomic force microscopy (AFM), contact angle measurements, and experimental set up. The contact angle measurements demonstrated that the hydrophilicities of the nanoporous PSF membranes were significantly enhanced by addition of a small amount of Tetronic‐1107 surfactant in the casting solution, along with using the lower CBT. It was also found that addition of Tetronic‐1107 in the casting solution along with increasing the CBT from 0 to 25°C incites formation of bigger pores on the top surface and results in formation of membranes with higher thickness and more porous structure in the sublayer. © 2012 Wiley Periodicals, Inc.

Structure orientation and micromechanical characterization of platelet‐reinforced polyethylene nanocomposites
Authors: Fan Y. , Lu Y. C. , Lou J. , Tang C. C. , Shinozaki D. M.
Published: May 2012

Clay reinforced polyethylene nanocomposites were prepared by melt mixing followed by transfer molding. The microstructure of the composites was characterized using Fourier transform infrared spectrometer and X‐ray diffraction. Results revealed the relative degree of particle orientation as a function of depth in the transferred molded materials. The particles were mostly oriented at the surface layers and randomly distributed at the core region. The anisotropy in mechanical properties due to clay orientations was characterized through novel dynamic microindentation test and analyzed by finite element simulation. When loaded in the flow direction (direction of clay orientations), the composites exhibited higher modulus at the surface than at the core; while loaded normal to the flow direction, the composites exhibited lower modulus at the surface than at the core. © 2012 Wiley Periodicals, Inc.

Authors: Bode A. , Franke J. , Rabe K. , Hornung M. , Wunderlich N. , Bertog S. C. , Sievert H.
Published: May 2012

Objective

This study evaluates short‐ and long‐term results of CAS with the Gore Flow Reversal System (GFRS).

Background

Embolic protection devices are of fundamental importance in carotid artery stenting (CAS). Proximal protection has potential advantages compared with distal protection. Limited data are available regarding the safety of the proximal GFRS.

Methods

CAS was performed with the GFRS. Patients' neurological status was assessed during the intervention and at follow‐up. Results of patients treated before 2006 were also compared to those of patients treated after 2006 because of changes in device design.

Results

CAS was performed in 86 patients with 87 stenoses (symptomatic in 37%). The procedure was technically successful in all cases. In 11 patients a transient periprocedural neurologic deficit occurred related to temporary cerebral flow compromise during balloon occlusion with complete resolution at completion of the procedure. The stroke/death rate at one month was 2.3% with a combined ipsilateral stroke and death rate at one year of 4.6%. There was no significant difference in event rates between the newer and older device version. Overall follow‐up time was 484 ± 3.4 patient years with a range of 0 to 119 months. The average yearly ipsilateral stroke rate including the first 30 days was 0.96%.

Conclusion

Our results demonstrate that CAS using the GFRS is safe whether the original or new device versions were used. The periprocedural stroke rate is at least as low as the stroke rate reported using distal protection. The long‐term stroke rate after CAS is low. © 2012 Wiley Periodicals, Inc.

Published: May 2012

Objective

To (1) compare the outcome of self‐expandable stents with versus without jailed deep femoral artery (DFA) for proximal superficial femoral artery (SFA) lesions, and to (2) ascertain the fate of jailed DFA.

Background

Complex SFA lesions involving the femoral bifurcation (FB) was mostly treated surgically, and the role played by endovascular procedures is uncertain.

Methods

We retrospectively identified 104 consecutive, de novo lesions involving the SFA ostium, stented between April 2005 and September 2010. Depending on the proximal stent edge location, the sample was divided between 60 distal common femoral artery (CFA) stenting with jailed DFA and 44 ostial SFA stenting without jailed DFA. The FB was the segment beginning in the distal CFA, 10 mm proximal to the DFA ostium and ending in the SFA and 10 mm distal to the carina. Stented CFA lesions proximal to the FB were excluded. The bifurcation was classified as patent when free of restenosis and repeat revascularization.

Results

The overall 12‐month bifurcation and primary patency rates were 72.5% and 52.0%, respectively. Predictors of loss of bifurcation patency were ostial SFA stenting and a small stent in the FB. Bifurcation patency (83.3% vs. 56.3%; P < 0.01) and primary patency of the SFA (56.2% vs. 37.5%; P = 0.088) were higher after distal CFA than after ostial SFA stenting. In 95.7% of distal CFA and 100% of ostial SFA stenting, DFA remained patent at 12‐month follow‐up (P = 0.237).

Conclusions

The 12‐month fate of jailed DFA after distal CFA stenting was acceptable, and the bifurcation patency rate was higher than after ostial SFA stenting. © 2012 Wiley Periodicals, Inc.

Experimental determination of laws of color harmony. Part 7: Experiments carried out with eyes adapted to light and dark
Authors: Nemcsics Antal , Takács Jenõ
Published: May 2012

Within the framework of our series of experiments, 16 artists made judgments on the harmony content of color compositions using two different methods. First, using the traditionally accepted method, at natural daylight, with their eyes adapted to light, they judged the compositions. Following that, they used, the nowadays more popular, instrumental simulation of the experimental color objects. The second part of the experiment was performed in a dark room and the subjects had their eyes adapted to dark, before the experiment. According to the outcome of these experiments, the results were substantially different. These differences were recorded in diagrams and formulated in mathematical form. Our conclusion, based on these results, is that the simulated experimental results cannot be used for the description of the harmony content between colors at natural conditions. The importance of these results has strong relevance to the judgment of color harmony between colors on the TV screen. To describe this particular harmony, we need a different word. © 2012 Wiley Periodicals, Inc. Col Res Appl, 38, 448–455, 2013.
The sox gene Dichaete is expressed in local interneurons and functions in development of the Drosophila adult olfactory circuit
Authors: Melnattur Krishna V. , Berdnik Daniela , Rusan Zeid , Ferreira Christopher J. , Nambu John R.
Published: May 2012

In insects, the primary sites of integration for olfactory sensory input are the glomeruli in the antennal lobes. Here, axons of olfactory receptor neurons synapse with dendrites of the projection neurons that relay olfactory input to higher brain centers, such as the mushroom bodies and lateral horn. Interactions between olfactory receptor neurons and projection neurons are modulated by excitatory and inhibitory input from a group of local interneurons. While significant insight has been gleaned into the differentiation of olfactory receptor and projection neurons, much less is known about the development and function of the local interneurons. We have found that Dichaete, a conserved Sox HMG box gene, is strongly expressed in a cluster of LAAL cells located adjacent to each antennal lobe in the adult brain. Within these clusters, Dichaete protein expression is detected in both cholinergic and GABAergic local interneurons. In contrast, Dichaete expression is not detected in mature or developing projection neurons, or developing olfactory receptor neurons. Analysis of novel viable Dichaete mutant alleles revealed misrouting of specific projection neuron dendrites and axons, and alterations in glomeruli organization. These results suggest noncell autonomous functions of Dichaete in projection neuron differentiation as well as a potential role for Dichaete‐expressing local interneurons in development of the adult olfactory circuitry. © 2012 Wiley Periodicals, Inc.

Life of a bifurcation in a gravel‐bed braided river
Authors: Bertoldi Walter
Published: May 2012

Channel bifurcation is a key element in braided rivers, determining the water and sediment distribution and hence controlling the morphological evolution. Recent theoretical and experimental findings, as well as field observations, showed that bifurcations in gravel‐bed braided rivers are often asymmetrical and highly unstable. In this paper field data are presented on a bifurcation in the Tagliamento River, northeast Italy. The planform configuration of the bifurcation and its temporal evolution was monitored by an automatic digital camera during a series of seven floods with different magnitudes. This remote sensing technique allowed a high temporal resolution (pictures were acquired every hour) that was proved to be essential in a highly dynamic system as the one considered here. Digitized maps of the channels provided information on the location of the bifurcation, the width of the anabranches, the angle between them, along with the occurrence and migration of sediment bars. Data were acquired at two different water levels, giving the possibility to compare low and high flow conditions. The monitored bifurcation is largely unstable and shows sudden changes in the water distribution, mainly driven by the bar migrating in the upstream channel and entering the distributaries. A relationship between width asymmetry and flood magnitude was observed, confirming previous analyses. Moreover, recent theoretical findings were applied, in order to test the possibility to estimate general trends in bifurcation evolution. The analysis pointed out the relevance of a correct assessment of the characteristic temporal scales, as the bifurcation evolves on a timescale similar to that of bar migration and flood duration. Understanding the interactions between these processes is therefore crucial in order to increase the ability to model and predict the morphological evolution of a braided network.
