Abstract
Marine ecosystems are complex, and there is increasing recognition that environmental, ecological, and human systems are linked inextricably in coastal regions. The purpose of this article was to integrate environmental, ecological and human dimensions information important for fisheries management into a common analytical framework. We then used the framework to examine the linkages between these traditionally separate subject areas. We focused on synthesis of linkages between the Gulf of Alaska marine ecosystem and human communities of practice, defined as different fisheries sectors. Our specific objective was to document the individual directional linkages among environmental, ecological, and human dimensions variables in conceptual models, then build qualitative network models to perform simulation analyses to test how bottom-up and top-down perturbations might propagate through these linkages. We found that it is both possible and beneficial to integrate environmental, ecological, and human dimensions information important for fisheries into a common framework. First, the conceptual models allowed us to synthesize information across a broad array of data types, representing disciplines such as ecology and economics that are more commonly investigated separately, often with distinct methods. Second, the qualitative network analysis demonstrated how ecological signals can propagate to human communities, and how fishery management measures may influence the system. Third, we found that incorporating multi-species interactions changed outcomes because the merged model reversed some of the ecological and human outcomes compared with single species analyses. Overall, we demonstrated the value of linking information from the natural and social sciences to better understand complex social–ecological systems, and the value of incorporating ecosystem-level processes into a traditionally single species management framework. We advocate for conceptual and qualitative network modelling as efficient foundational steps to inform ecosystem-based fisheries management.
Arteriogenesis versus angiogenesis
Authors: Carmeliet Peter , Eelen Guy , Kalucka Joanna 
Published: March 2017

Abstract
Higher organisms have a cardiovascular circulatory system with blood vessels to supply vital nutrients and oxygen to distant tissues. It is therefore not surprising that vascular disorders are leading causes of mortality. Understanding how new blood vessels form, creates opportunities to cure these life-threatening diseases. After birth, growth of blood vessels mainly occurs via two distinct mechanisms depending on the initial trigger: angiogenesis (referred here as capillary sprouting) is induced primarily by hypoxia, whereas arteriogenesis (referred here as the rapid enlargement of pre-existing collateral arteries, induced by vascular occlusion) is mainly driven by fluid shear stress. Arteriogenesis allows conductance of much larger volumes of blood per unit of time than does the increase in capillary density during angiogenesis. Notwithstanding these major differences, angiogenesis and arteriogenesis share a number of underlying mechanisms, e.g. the involvement of growth factor signalling. This chapter highlights the cellular and molecular events driving the two processes and discusses the therapeutic potential of targeting angiogenesis in cancer and arteriogenesis in cardiovascular diseases.
Atherosclerosis—a short history
Authors: Monaco Claudia , Lutgens Esther 
Published: March 2017

Abstract
The pathogenesis of human atherosclerotic lesions has long been debated and is still evolving nowadays. First conceptualized as chronically evolving degenerative disease initiating in the mother’s womb, then increasingly accepted as a dynamic process causing severe acute complications that jeopardize the blood flow to the heart. Evolution of the hypothesis mirrored the progress of cellular and molecular biology, leading to progressive broadening of the understanding of cell types and molecules involved in atherogenesis. This chapter describes the current histopathological view on the pathogenesis of atherosclerosis, and touches on a historical perspective weaving in the fundamental discoveries that still influence the perception of this disease in humans.
Pathogenesis of atherosclerosis: lipid metabolism
Authors: Wiklund Olov , Borén Jan 
Published: March 2017

Abstract
Lipids are carried in plasma as microparticles, lipoproteins, composed of a core of hydrophobic lipids and a surface of amphipathic lipids. In addition, the particles carry proteins (i.e. apolipoproteins). The proteins have key functions in the metabolism as receptor ligands, enzymes or activators. Lipoproteins are classified based on density into: chylomicrons, VLDL, IDL, LDL, and HDL. Retention of apoB-containing lipoproteins (LDL, IDL, and VLDL) in the arterial intima is the initiating event in the development of atherosclerosis. Retention is mediated by binding of apoB to structural proteoglycans in the intima. Increased plasma concentration of apoB-containing lipoproteins is the main risk factor for atherosclerotic cardiovascular disease (CVD) and the causative role of LDL has been demonstrated in several studies. Lp(a) is a subclass of LDL and elevated Lp(a) is an independent risk-factor, primarily genetically mediated. Genetic data support that high Lp(a) causes atherosclerosis. Elevated triglycerides in plasma are associated with increased risk for CVD. Whether triglycerides directly induce atherogenesis is still unclear, but current data strongly support that remnant particles from triglyceride-rich lipoproteins are causal. HDL are lipoproteins that have been considered to be important for reversed cholesterol transport. Low HDL is a strong risk-factor for CVD. However, the causative role of HDL is debated and intervention studies to raise HDL have not been successful. Reduction of LDL is the main target for prevention and treatment, using drugs that inhibit the enzyme HMG-CoA reductase, i.e. statins. Other drugs for LDL reduction and to modify other lipoproteins may further reduce risk, and new therapeutic targets are explored.
Biomechanical theories of atherosclerosis
Authors: Wentzel Jolanda J. , Rowland Ethan M. , Weinberg Peter D. , Krams Robert 
Published: March 2017

Abstract
Atherosclerosis, the disease underlying most heart attacks and strokes, occurs predominantly at certain well-defined sites within the arterial system. Its development may therefore depend not only on systemic risk factors but also on locally varying biomechanical forces. There are three inter-related theories explaining the effect of biomechanics on atherosclerosis. In the first theory, a central role is played by lipid transport into the vessel wall, which varies as a result of mechanical forces. In the second theory, haemodynamic wall shear stress-the frictional force per unit area of endothelium arising from the movement of blood-activates signalling pathways that affect endothelial cell properties. In the third, strain-the stretch of the wall arising from changes in blood pressure-is the key biomechanical trigger. All three theories are discussed from historical, molecular, and clinical perspectives.
Atherosclerosis: cellular mechanisms
Authors: Lutgens Esther , Bochaton-Piallat Marie-Luce , Weber Christian 
Published: March 2017

Abstract
Atherosclerosis is a lipid-driven, chronic inflammatory disease of the large and middle-sized arteries that affects every human being and slowly progresses with age. The disease is characterized by the presence of atherosclerotic plaques consisting of lipids, (immune) cells, and debris that form in the arterial intima. Plaques develop at predisposed regions characterized by disturbed blood flow dynamics, such as curvatures and branch points. In the past decades, experimental and patient studies have revealed the role of the different cell-types of the innate and adaptive immune system, and of non-immune cells such as platelets, endothelial, and vascular smooth muscle cells, in its pathogenesis. This chapter highlights the roles of these individual cell types in atherogenesis and explains their modes of communication using chemokines, cytokines, and co-stimulatory molecules.
Molecular mechanisms
Authors: Monaco Claudia , Caligiuri Giuseppina 
Published: March 2017

Abstract
The development of the atherosclerotic plaque relies on specific cognate interactions between ligands and receptors with the ability to regulate cell recruitment, inflammatory signalling, and the production of powerful inflammatory and bioactive lipid mediators. This chapter describes how signalling is engaged by cell-cell surface interactions when the endothelium interacts with platelets and leukocytes enhancing leukocyte recruitment during atherogenesis. It also exemplifies intracellular signalling pathways induced by the activation of innate immune receptors, the most potent activators of inflammation in physiology and disease. Differences are highlighted in innate signalling pathways in metabolic diseases such as atherosclerosis compared to canonical immunological responses. Finally, the key lipid mediators whose production can affect endothelial function, inflammation, and atherosclerosis development are summarized. This Chapter will take you through these fundamental steps in the development of the atherosclerotic plaque by summarizing very recent knowledge in the field and highlighting recent or ongoing clinical trials that may enrich our ability to target cardiovascular disease in the future.
Pathophysiology of vasculitis
Authors: Tombetti Enrico , Mason Justin C. 
Published: March 2017

Abstract
Vasculitis represents a spectrum of disorders that are often divided on the basis of the predominant vessel size affected into large-, medium- and small-vessel vasculitides. This chapter will focus on the pathogenesis of the anti-neutrophil cytoplasmic antibody (ANCA)-associated medium- and small-vessel vasculitides (AAV), and large-vessel vasculitis, Takayasu arteritis, and giant cell arteritis. Underlying pathogenic mechanisms in vasculitis remain to be fully understood. In particular, the initiating event(s) are not known. A combination of infectious or other environmental triggers on a susceptible genetic background is currently favoured. In addition to the vessel size affected, the mechanisms of vascular injury vary. Moreover, extravascular granulomatosis may play an important role in disease manifestations. The innate and adaptive immune systems contribute to its pathogenesis. Although pathogenic antibodies have not been identified in large-vessel vasculitis, ANCA are directly implicated in small- and medium-vessel AAV. Disease manifestations are varied and diverse and may include arterial stenosis or aneurysms, glomerulonephritis and renal failure, gastro-intestinal, pulmonary, cutaneous, and neurological complications, visual disturbance, deafness, and nasal bridge collapse. Life-threatening cardiovascular disease is also seen, with myocarditis, pericarditis, valvular heart disease, thrombosis, systemic and pulmonary arterial hypertension, and accelerated coronary heart disease all reported. Despite this, the prognosis for patients with vasculitis has improved significantly in recent decades. Further understanding of the pathogenesis of vasculitis will lead to the discovery of further therapeutic targets and novel, safer biologic therapies.
Binaural Interaction Effects of 30–50 Hz Auditory Steady State Responses
Authors: Gransier Robin , van Wieringen Astrid , Wouters Jan 
Published: March 2017

Objectives:
Auditory stimuli modulated by modulation frequencies within the 30 to 50 Hz region evoke auditory steady state responses (ASSRs) with high signal to noise ratios in adults, and can be used to determine the frequency-specific hearing thresholds of adults who are unable to give behavioral feedback reliably. To measure ASSRs as efficiently as possible a multiple stimulus paradigm can be used, stimulating both ears simultaneously. The response strength of 30 to 50Hz ASSRs is, however, affected when both ears are stimulated simultaneously. The aim of the present study is to gain insight in the measurement efficiency of 30 to 50 Hz ASSRs evoked with a 2-ear stimulation paradigm, by systematically investigating the binaural interaction effects of 30 to 50 Hz ASSRs in normal-hearing adults.

Design:
ASSRs were obtained with a 64-channel EEG system in 23 normal-hearing adults. All participants participated in one diotic, multiple dichotic, and multiple monaural conditions. Stimuli consisted of a modulated one-octave noise band, centered at 1 kHz, and presented at 70 dB SPL. The diotic condition contained 40 Hz modulated stimuli presented to both ears. In the dichotic conditions, the modulation frequency of the left ear stimulus was kept constant at 40 Hz, while the stimulus at the right ear was either the unmodulated or modulated carrier. In case of the modulated carrier, the modulation frequency varied between 30 and 50 Hz in steps of 2 Hz across conditions. The monaural conditions consisted of all stimuli included in the diotic and dichotic conditions.

Results:
Modulation frequencies ≥36 Hz resulted in prominent ASSRs in all participants for the monaural conditions. A significant enhancement effect was observed (average: ~3 dB) in the diotic condition, whereas a significant reduction effect was observed in the dichotic conditions. There was no distinct effect of the temporal characteristics of the stimuli on the amount of reduction. The attenuation was in 33% of the cases >3 dB for ASSRs evoked with modulation frequencies ≥40 Hz and 50% for ASSRs evoked with modulation frequencies ≤36 Hz.

Conclusions:
Binaural interaction effects as observed in the diotic condition are similar to the binaural interaction effects of middle latency responses as reported in the literature, suggesting that these responses share a same underlying mechanism. Our data also indicated that 30 to 50 Hz ASSRs are attenuated when presented dichotically and that this attenuation is independent of the stimulus characteristics as used in the present study. These findings are important as they give insight in how binaural interaction affects the measurement efficiency. The 2-ear stimulation paradigm of the present study was, for the most optimal modulation frequencies (i.e., ≥40 Hz), more efficient than a 1-ear sequential stimulation paradigm in 66% of the cases.
Undifferentiated connective tissue disease, fibromyalgia and the environmental factors
Authors: Andreoli Laura , Tincani Angela 
Published: March 2017

Purpose of review
The aim of this study was to discuss the role of environmental factors in the induction and perpetuation of autoimmunity, with particular focus on undifferentiated connective tissue disease (UCTD) and fibromyalgia. These two entities may share undefined clinical and laboratory features and recognize environmental exposures as triggering factors. From this particular point of view, both UCTD and fibromyalgia may resemble the picture of the ‘Autoimmune/Inflammatory Syndrome Induced by Adjuvants’ (ASIA).

Recent findings
A case–control study on environmental exposures showed that patients with UCTD were significantly more exposed to several adjuvants (vaccines, metal implants, proximity to metal factories and foundries) than age and sex-matched healthy controls. UCTD exposed to major ASIA triggers (vaccines, silicone) displayed typical features of ASIA (general weakness, chronic fatigue, irritable bowel syndrome) in the context of a predisposing genetic background (familiarity for autoimmunity).

Summary
The induction and perpetuation of autoimmunity is a complex process that requires the interaction between the individual genetic background and the environment. Environmental factors are gaining increasing attention since the description of ASIA, a syndrome that includes symptoms typically seen in patients with fibromyalgia and UCTD. A recent case–control study focusing on environmental exposures suggested that nearly half of patients with UCTD may fall within the ASIA spectrum.

Authors: Ortega-Castillejos Dell Kristie A. , Pathomvanich Damkerng 
Published: March 2017

BACKGROUND
Hair density, together with hair diameter has a tremendous impact on the cosmetic outcome of hair transplantation surgery.

OBJECTIVE
This retrospective study aims to assess the average number of follicular unit (FU) grafts in the donor area of Asian men with androgenetic alopecia.

METHODS
Seventy patients (ages 24–65 years old) with virgin scalp who had their first hair transplantation were included. During the harvesting procedure, a 2- to 3-cm-wide area of the donor site was shaved from ear to ear with 5 specific areas assigned as reference points for the study namely the central occipital area, left and right parietal and temporal areas. A video microscope was used to capture the field of each reference point. Follicular units in each area were counted and the number of 1-hair, 2-hair, and 3-hair follicular groupings was recorded.

RESULTS
East and Southeast Asians had an average of 61.1 FU/cm2 (111.2 hairs/cm2); West Asians had an average density of 63.6 FU/cm2 (126.8 hairs/cm2); South Asians were noted to have an average density of 63.5 FU/cm2 (126.8 hairs/cm2).

CONCLUSION
Asian hair density has slight variations in the number of FU grafts in each donor area.
GOOD VISUAL OUTCOME AT 1 YEAR IN NEOVASCULAR AGE-RELATED MACULAR DEGENERATION WITH PIGMENT EPITHELIUM DETACHMENT
Authors: de Massougnes Sophie , Dirani Ali , Mantel Irmela 
Published: March 2017

Purpose:
To evaluate baseline and treatment factors influencing the response of pigment epithelial detachment (PED) in patients with treatment-naive neovascular age-related macular degeneration after 1 year of intravitreal anti–vascular endothelial growth factor treatment.

Methods:
This retrospective consecutive case series study included 104 eyes (94 patients) with treatment-naive neovascular age-related macular degeneration and associated PED >150 μm treated with aflibercept (n = 41) or ranibizumab (n = 63) for at least 1 year. Stepwise linear regression was used to assess factors influencing best-corrected visual acuity and PED response.

Results:
At 1 year, the best-corrected visual acuity improved from 20/63+1 (60.8 ± 15.9 Early Treatment of Diabetic Retinopathy Study letters) at baseline to 20/40−1 (69.0 ± 15.0 letters) (P = 0.001), and PED maximal height decreased from 370.8 ± 205.6 μm to 238.8 ± 178.5 μm (P = 0.001). Multivariate analysis revealed an association of the visual improvement with lower best-corrected visual acuity at baseline (P = 0.001), the presence of foveal subretinal fluid (P = 0.001), and female gender (P = 0.047). Pigment epithelial detachment height reduction was dependent on higher baseline PED height (P = 0.001) and treatment drug (P = 0.008).

Conclusion:
Visual improvement in neovascular age-related macular degeneration with PED was equally achieved with ranibizumab and aflibercept, influenced mainly by baseline best-corrected visual acuity and foveal subretinal fluid. Pigment epithelial detachment height reduction was influenced by baseline height and the treatment drug, favoring aflibercept for a stronger effect. The clinical significance of this result warrants further studies.

Published: March 2017

Purpose:
The aim is to study the effects of cigarette smoking on the structural and functional alterations of the macula in eyes of healthy young smokers.

Methods:
Cross-sectional clinical study included 100 active smokers (Group 1) and 100 age- and sex-matched healthy passive smokers (Group 2). All participants underwent a complete ophthalmologic assessment, axial length measurement, central corneal thickness measurement, spectral domain optical coherence tomography, and multifocal electroretinogram. Urine samples were collected to measure urinary levels of cotinine and creatinine with subsequent calculation of the cotinine creatinine ratio.

Results:
Central foveal thickness (255.62 ± 17.23 and 264.75 ± 17.35 μm, respectively, with P = 0.0003) and subfoveal choroidal thickness (377.48 ± 30.32 and 385.08 ± 21.10 μm, respectively, with P = 0.04) were significantly lower in active smokers than those of passive smokers. Retinal response density of ring 1 (31.08 ± 2.29 and 33.46 ± 3.83 nV/deg2, respectively, with P < 0.001) and Ring 1 (R1) P1 amplitude (0.81 ± 0.07 and 0.95 ± 0.16 μV, respectively, with P < 0.001) were significantly lower, whereas R1 P1 latency (43.02 ± 0.97 and 40.39 ± 2.08 milliseconds, respectively, with P < 0.001) was significantly longer in active smokers than those of passive smokers. The mf-ERG ring ratios were significantly lower in the active smokers than those of passive smokers.

Conclusion:
In the absence of clinically apparent foveal toxicity, CFT, SFCT together with ring amplitude ratio could be used as good predictors of subclinical nicotine induced foveal changes.
SHORT-TERM OUTCOMES OF HYBRID 23-, 25-, AND 27-GAUGE VITRECTOMY FOR COMPLEX DIABETIC TRACTIONAL RETINAL DETACHMENT REPAIR
Authors: Khan M. Ali , Samara Wasim A. , Hsu Jason , Garg Sunir 
Published: March 2017

Purpose:
To describe the short-term outcomes of complex diabetic retinal detachment repair using hybrid 23-gauge or 25-gauge vitrectomy instruments with a 27-gauge vitrectomy system.

Methods:
Retrospective, interventional, consecutive case series. Ten eyes of 10 patients undergoing hybrid pars plana vitrectomy for diabetic tractional retinal detachment were reviewed.

Results:
Combined use of 25-gauge and 27-gauge instrumentation was used in 8 of 10 eyes and combined use of 23-gauge and 27-gauge instrumentation in 2 of 10 eyes. In all cases, a 27-gauge vitreous cutter was used for membrane dissection and delamination. All eyes had successful anatomical reattachment at a mean follow-up of 207 ± 55 days. Snellen visual acuity improved from a mean of 20/822 preoperatively to 20/566 at the final follow-up (P = 0.55). Mean intraocular pressure remained stable at 13 ± 3.4 mmHg preoperatively to 13.6 ± 5.4 mmHg at the final follow-up (P = 0.76). No intraoperative or postoperative complications were encountered.

Conclusion:
Concurrent use of the 27-gauge vitreous cutter with 23-gauge or 25-gauge instrumentation was effective during diabetic tractional retinal detachment repair. This hybrid technique was not associated with any significant intraoperative or short-term postoperative complications.
