Authors: Duda S. H. , Wehrmann M. , Haase K. K. , Huppert P. E. , Karsch K. R. , Claussen C. D.
Published: June 2015

This experimental study was designed to define the potential value of a mid-infrared holmium laser in the free running mode for angioplasty. Immediately after removal, fresh normal and diseased human cadaveric arteries were irradiated under saline with a Ho:YAG laser (wavelength 2.13 μm). The laser was pulsed at 3 Hz, 250 μs pulse width and fluences of 10 to 40 J/cm2. The laser beam was coupled to ring catheters with multiple low-OH quartz fibers. The tip of the delivery device was held in direct contact with the vessel surface with the laser beam oriented perpendicularly. Ablation of atherosclerotic plaque was accomplished at an ablation threshold of 10 J/cm2. The ablation rate was 2.1 to 8.3 μm/pulse. Removal of calcified plaque was only partially effective. There were marked thermal effects with vacuolizations extending up to 1505 ± 178 μm into the adjacent tissue. Laser light at the mid-infrared wavelength of 2.13 μm is supposed to be attractive as it is readily absorbed in water and can easily be transmitted through optical fibers. However, Q-switching seems to be essential to minimize thermal side effects and to make effective ablation of calcium possible.

Authors: Albrechtsson U. , Lárusdóttir H. , Norgren L. , Lundby B.
Published: June 2015

In 26 patients iodixanol, a new nonionic dimer, isotonic to blood in all concentrations, was used as contrast medium in aortofemoral angiography. Half of the patients received contrast medium in a concentration of 270 mg I/ml and the other half 320 mg I/ml. The aim of the trial was to evaluate the safety and tolerability of iodixanol and the radiographic efficacy of the two concentrations. The degree of discomfort, adverse events, changes in serum chemistry parameters, and diagnostic information were assessed. There were no changes or trends of clinical importance in serum chemistry parameters. The side effects were mild and consisted mostly of some sensation of warmth of short duration. No other adverse events were seen. The overall radiographic efficacy did not show any significant difference between the two concentrations. This indicates that iodixanol is safe and well tolerated when used in adult femoral angiography.

Authors: Mattila K. T. , Komu M. E. S. , Koskinen S. K. , Niemi P. T.
Published: June 2015

Magnetization transfer contrast (MTC) technique provides a new type of contrast in MR imaging. The MTC method is based on the interaction between the spins of free protons and those with restricted motion. Exercise-induced changes in signal intensity and MTC were measured in the forearm muscles of 10 volunteers at 0.1 T. There was 26% increase in signal intensity of active flexor muscles after exercise when imaged with ordinary gradient echo sequence. Despite this marked intensity increase, the postexercise values of MTC did not differ from the preexercise ones.
Diagnosis of Ganglions in the Hand and Wrist by Sonography
Authors: Höglund M. , Tordai P. , Muren C.
Published: June 2015

In the practice of hand surgery, imaging of soft tissue structures can provide useful information for diagnosis and preoperative planning. Sonography with high frequency technique giving high spatial resolution is especially rewarding. In a joint project of the Departments of Radiology and Hand Surgery we evaluated the diagnostic accuracy and clinical value of sonographic assessment of ganglions of the hand and wrist. The material comprises 68 soft tissue lesions clinically suspected to be ganglions. Sonography revealed a ganglion in 53 cases, 34 of which went to surgery. The diagnosis was confirmed in every case. One collapsed ganglion was missed. Nonpalpable ganglions causing clinical symptoms could be demonstrated, and a suspected ganglion could sometimes be ruled out in favor of other diagnoses. Sonography could delineate the entire ganglion and often its connection with the joint space.
Preembolization Functional Evaluation in Supratentorial Cerebral Arteriovenous Malformations with Superselective Intraarterial Injection of Thiopental Sodium Solution
Authors: Han M. H. , Chang K. H. , Han D. H. , Yeon K. M. , Han M. C.
Published: June 2015

Superselective intraarterial injections of thiopental sodium solution for evaluation of local brain function were performed before embolization in 38 consecutive patients with supratentorial arteriovenous malformations to evaluate the role of the test using thiopental sodium solution. Thiopental sodium (30–50 mg) was injected in 68 arteries (44 middle cerebral arteries, 13 anterior cerebral arteries, 7 posterior cerebral arteries, 3 external carotid arteries, and 1 thalamo-perforating artery) through superselective microcatheters just before the injection of cyanoacrylate mixture for the embolization. The test was negative in 57 arteries and there were neurologic dysfunctions in 3 of them after embolization. The neurologic deficits in these cases were caused by reflux of embolic material, spasm of the main arterial trunk, or neglected mild sensory change, respectively, and there was no real false-negative test. The embolization could not be performed due to positive test in 9 arteries. Two arteries with positive tests but acceptable symptoms were embolized and the same neurologic deficits developed immediately after embolization. There was no local arterial complication by an injection of the thiopental sodium solution. All neurologic deficits caused by positive tests developed immediately and were completely relieved within 5 min without specific management. Superselective intraarterial injection of thiopental sodium solution is a safe and reliable test for the evaluation of local brain function before embolization of supratentorial arteriovenous malformations.

Fine Needle Aspiration Biopsy of Hydatid Cysts
Authors: von Sinner W. N. , Nyman R. , Linjawi T. , Ali A. M.
Published: June 2015

Fine needle aspiration biopsy (FNAB) was performed in 31 patients with hydatid disease by 15 operators in 41 biopsy events during the period 1983–93. The FNABs were unintentionally done without prior clinical suspicion of hydatid cysts (HCs) in 18 patients and intentionally (with prior clinical suspicion of HC) in 13 patients for pathologic confirmation required for specific therapy. The FNABs were performed with the guidance of fluoroscopy (n=7), CT (n= 14) or ultrasonography (n= 10). The material included both closed, open and ruptured HCs from different locations such as abdomen, thorax, spine and bone. Pathologic confirmation of HC was achieved by recovering and demonstrating parasitic material in the specimen. In only 7 of 31 patients were the specimens diagnostic at the initial interpretation. This emphasizes the importance of alerting the pathologist about the possibility of hydatid disease.

In 25 of 31 patients (81%) no biopsy reactions occurred. In 5 patients minor allergic reactions occurred and 3 had filling of air into intrathoracic cysts not requiring therapy. One patient, with a FNAB of a liver HC, had a sudden severe drop in blood pressure, which required anti-shock therapy with subsequent recovery without sequelae. All complications occurred with non-intentional biopsy of HC. Suggestions for diagnostic and therapeutic management of patients with HC and advice to avoid or limit potential complications or spread of disease are given where a planned biopsy is necessary for appropriate and effective therapy.
Evaluation of Volume Selection Methods in in Vivo MRS
Authors: Starck G. , Lundin R. , Forssell-Aronsson E. , Arvidsson M. , Alpsten M. , Ekholm S.
Published: June 2015

In vivo MR spectroscopy (MRS) requires some kind of volume selection method to be able to measure the signal from a selected part of the body. To be able to interpret the spectra correctly, the quality of the volume selection must be investigated for each new MRS application using phantom measurements. A new phantom, especially suitable for precision measurements of the volume selection performance, is presented. It contains a small, remotely controlled signal source placed inside a larger vessel. This principle can be applied to various body regions, coil types and nuclei. The measurement conditions are close to the clinical situation. The phantom does not have to be repositioned during a signal profile measurement and the signal contribution from each point along the profile is determined regarding sign and amplitude.
CT and MR Imaging of Adrenal Hemangioma
Authors: Rieber A. , Brambs H.-J.
Published: June 2015

Purpose:

Cavernous hemangiomas of the adrenal gland are rare, and we here describe CT and MR features of an additional case including delayed contrast CT.

Results:

On CT, the tumor appeared as a well-delineated mass. Fatty areas and calcifications were seen. On delayed contrast CT, a progressive enhancement from the periphery to the center of the tumor was noticed, similar to the contrast enhancement of liver hemangiomas. In T1-weighted MR images, a hypointense tumor with a central stellate area of hypointensity was found. The tumor had a predominantly peripheral contrast enhancement.

Conclusion:

CT and MR findings of adrenal hemangiomas are in some cases similar to those of liver hemangiomas. A tumor resection must be considered if the tumor changes in appearance or size.
Thin-Section CT in the Examination of Cervical Disc Herniation
Authors: Ilkko E. , Lähde S. , Heiskari M.
Published: June 2015

Purpose:

The aim of the investigation was to determine whether thin-section high-resolution CT imaging could replace MR imaging and/or myelography in preoperative evaluation of radiculopathy and/or myelopathy.

Material and Methods:

A total of 120 patients, referred for cervical myelography (n=107) or MR imaging (n=13), were further examined with 1-mm non-contrast CT of the suspected disc space, including at least the next cephalic and caudal interspaces. Thirty-seven patients underwent Cloward's operation, at which 32 were found to have disc herniation.

Results:

The sensitivities of CT (n=37), myelography (n=29), and MR imaging (n=8) were 66%, 84%, and 86%, respectively. The corresponding figures for false-positives were 8%, 10%, and 13%. Artefacts caused by wide shoulders in the 1-mm CT images were estimated to have contributed to a false-negative finding in 8 cases. The remaining 3 false-negatives were retrospectively considered evaluation errors. The true-positive CT findings usually presented with a local disc bulge measuring over 80 HU in density. Local ligamentous hypertrophy presented an indistinguishable finding in 3 cases, yielding false-positive CT findings.

Conclusion:

Conventional thin-section CT is considered a usable alternative for the evaluation of suspected cervical disc herniations in selected patients. Stocky patients with wide shoulders and a short neck are not suitable candidates, even when new generation equipment is available.
Changes in the Anal Sphincter with Age
Authors: Nielsen M. B. , Pedersen J. F.
Published: June 2015

Purpose:

To describe the changes in the endosonographic appearance of the anal sphincter muscles with age.

Material and Methods:

Fifty subjects (age range 22–85 years) with no history of anorectal disease or surgery were studied with anal endosonography. The thickness of the internal and external anal sphincter was registered and correlated to age. For the internal sphincter, which is often asymmetric, the maximum and minimum thicknesses were measured at any part of the circumference (except anteriorly for anatomic reasons) and also in the lateral positions.

Results:

A significant positive correlation with age was found for all maximum, minimum, and average internal sphincter thicknesses. Moreover, the echogenicity of the internal sphincter changed with age as the sphincter muscle became more echogenic. There was no significant correlation between external sphincter thickness and age.

Conclusion:

Knowledge of the normal variation of the internal sphincter thickness with age is important since endosonography may be used to identify patients with hypertrophy of the internal sphincter. Currently, we consider maximal thicknesses above 4 mm to be abnormal in patients under 50 years of age, whereas in patients aged at least 50 years thicknesses of 5 mm or more are considered abnormal.

Radiological Bile Acid Absorption Test 75SeHCAT in Patients with Diarrhoea of Unknown Cause
Authors: Rudberg U. , Nylander B.
Published: June 2015

Purpose:

The purpose with this study was to investigate the usefulness of the 75SeHCAT test in patients suffering from “functional” diarrhoea and to disclose earlier radiological investigations performed in the course of disease.

Material and Methods:

Twenty patients with chronic diarrhoea of unknown cause were investigated with the 75SeHCAT test. The cholestyramine test and an estimation of oro-caecal transit time (OCTT) were also performed in 13 and 10 patients respectively.

Results:

Ten patients had low 7-day retention (≤15%). Nine of these were tested with cholestyramine and 8 showed complete relief from the diarrhoea. The cholestyramine test had no effect on the 4 patients with normal bile acid retention. No correlation was found between the retention of 75SeHCAT and OCCT. A total of 80 inconclusive gastrointestinal barium examinations were performed during the course of disease.

Conclusion:

Pathological bile acid retention, studied with the radiological 75SeHCAT test, is common in patients with diarrhoea of unknown cause. The test should be performed earlier in the course of disease in order to prevent unnecessary radiological investigations and to reduce patient suffering and distress.
Lingual Carcinoma

Published: June 2015

Purpose:

To determine the utility of MR imaging in the evaluation of lingual carcinomas.

Material and Methods:

Eleven patients with lingual carcinoma were evaluated with MR imaging including dynamic study within one week before surgery. Nine patients underwent preoperative chemotherapy or irradiation, and 2 patients had no preoperative treatment. Delineation of the tumor, the contrast between tumor and surrounding tissue, and extent of the tumor were evaluated in a blinded manner. After glossectomy, MR images were correlated with pathological findings. Statistical analysis was performed on the visual assessment ratings.

Results:

Blinded evaluation suggested that dynamic and T2-weighted images (T2WI) were significantly superior to postcontrast T1WI in demonstrating the lesion. There were no significant differences between dynamic MR images and T2WIs. However, histopathological correlation showed that in patients with preoperative treatment, dynamic MR imaging demonstrated more accurately the size and extent of the residual tumor than did T2WI and postcontrast T1WI, which tended to demonstrate an area of signal abnormality that was more extensive than the true size of the residual lesion. In patients without preoperative treatment, dynamic MR imaging, T2WI, and postcontrast T1WI gave an equivalent depiction of the extent of the carcinoma.

Conclusion:

In patients with no preoperative treatment, dynamic MR imaging does not appear to offer any advantage over T2WI. However, in patients with preoperative treatment, dynamic MR imaging provides a more accurate assessment of the residual tumor than do T2WI and postcontrast T1WI.
Assessment of exposure to cadmium, lead, manganese, and nickel in workers from foundries
Authors: dos Santos Claudia Regina , da Silva Carlos Sérgio , Nascimento Elizabeth Souza
Published: June 2015

Objectives:

In this study, biological exposure indicators were used to assess the exposure of workers to cadmium (Cd), lead (Pb), manganese (Mn), and nickel (Ni) in nonferrous metal smelters.

Methods:

A total of 273 male participants (178 exposed and 95 nonexposed control group), working in nonferrous metal foundries located in southern Brazil, were evaluated based on biological indicators, environmental levels, and different types of work performed by the participants. Blood Pb (BPb), urinary Cd (UCd), urinary Mn (UMn), and urinary Ni (UNi) levels were quantified by graphite furnace atomic absorption spectrometry with Zeeman background correction.

Results:

Significant differences between the exposed and nonexposed groups were observed for all of the analyzed elements. The average levels of BPb were higher than the recommended occupational exposure level. Relatively low concentrations were found for UCd, UMn, and UNi.

Conclusions:

Although metal production is an important segment of the Brazilian economy, information related to employee health in this sector is scarce. The environmental levels are determinant in occupational exposure in foundries. In companies where air levels of Pb, Cd, and Mn were above the established limits, the different types of activity did not represent an important influence on the biological levels found among workers. In situations with low air levels of these metals, the workers from the “melting” sector were actually more vulnerable.
Determinants of Propranolol’s Selective Effect on Loss Aversion
Authors: Sokol-Hessner Peter , Lackovic Sandra F. , Tobe Russell H. , Camerer Colin F. , Leventhal Bennett L. , Phelps Elizabeth A.
Published: June 2015

Research on emotion and decision making has suggested that arousal mediates risky decisions, but several distinct and often confounded processes drive such choices. We used econometric modeling to separate and quantify the unique contributions of loss aversion, risk attitudes, and choice consistency to risky decision making. We administered the beta-blocker propranolol in a double-blind, placebo-controlled within-subjects study, targeting the neurohormonal basis of physiological arousal. Matching our intervention’s pharmacological specificity with a quantitative model delineating decision-making components allowed us to identify the causal relationships between arousal and decision making that do and do not exist. Propranolol selectively reduced loss aversion in a baseline- and dose-dependent manner (i.e., as a function of initial loss aversion and body mass index), and did not affect risk attitudes or choice consistency. These findings provide evidence for a specific, modulatory, and causal relationship between precise components of emotion and risky decision making.
Recent anxiety symptoms and drug use associated with sexually transmitted infection diagnosis among an online US sample of men who have sex with men
Authors: Downing Martin J , Chiasson Mary Ann , Hirshfield Sabina
Published: June 2015

The extent to which mental health problems, including current anxiety and depressive symptoms, may co-occur, or are associated, with the acquisition of sexually transmitted infections other than HIV remains largely unexplored among men who have sex with men. In a cross-sectional survey of 8,381 US men who have sex with men recruited from a sexual networking website, 15 percent reported a past 60-day sexually transmitted infection diagnosis. Among HIV-negative men, increased odds of reporting a sexually transmitted infection were associated with current anxiety symptoms and past 60-day drug use. Findings underscore the need to better understand causal pathways among anxiety, drug use, and sexually transmitted infection acquisition and transmission among men who have sex with men.
The influence of reasons for attending university on university experience: A comparison between students with and without disabilities
Authors: Reed Maureen J , Kennett Deborah J , Emond Marc
Published: June 2015

Students choose to go to university for many reasons. They include those with disabilities and those without. The reasons why students with disabilities go to university and how these reasons impact university experience, including coping (academic resourcefulness), adapting, academic ability beliefs (academic self-efficacy), and grades, are investigated. Results show that unlike non-disabled peers, first-year students with disabilities who go to university for internal reasons (e.g. for the challenge, because they like learning) show higher academic resourcefulness and self-efficacy, and that those disabled students who choose to go to university in order to get a better job show higher academic self-efficacy. Upper-year students with disabilities less often choose to go to university for others and in order to get a better job than counterparts without disabilities. Upper-year students with disabilities less often choose to go to university for the university features (e.g. student services) than first-year students with disabilities. Upper-year students with disabilities choosing to go to university in order to delay responsibilities are less adapted, and those choosing to go for the reason of getting a better job have lower grades. Recommendations on strategies to increase student coping and self-efficacy and the need for qualitative research are made.
Measurement and analysis of the internal flow field in the hydrodynamic torque converter with adjustable guide vanes
Authors: Wenxing Ma , Hao Liu , Chunbao Liu , Changsuo Liu
Published: June 2015

This article presents a particle-tracking velocimetry experiment for studying internal flows of hydrodynamic torque converter whose guide vanes are adjustable. The torque converter in which the flow region is an enclosed space with multiple impellers has a complicated geometry of impellers. Complex flows in adjustable stator are experimentally analyzed using particle-tracking velocimetry, and some advanced measurement technique has been successfully applied. Under each opening, using the single-frame and triple-exposure method, images of the flow fields in the adjustable stator were recorded at three typical working conditions as the speed ratios were equal to 0 (stall), 0.5 (design), and 1 (idle). According to particle trajectories on the images, the displacements and corresponding velocity vectors were obtained. The internal flow pattern of the hydrodynamic torque converter with adjustable guide vanes were acquired and analyzed in two cases: the changing conditions under the same opening and the changing openings under the same condition.
Obinutuzumab for the treatment of patients with previously untreated chronic lymphocytic leukemia: overview and perspective
Authors: Owen Carolyn J. , Stewart Douglas A.
Published: June 2015

Chronic lymphocytic leukemia (CLL) is the most common lymphoproliferative disorder in the Western world and predominantly affects older people. Until recently, most studies in CLL focused on younger patients in whom intensive therapy with the addition of rituximab to fludarabine and cyclophosphamide was shown to improve survival. Obinutuzumab is a novel type II anti-CD20 monoclonal antibody (mAb) that recently demonstrated an overall survival advantage when combined with chemotherapy in previously untreated older patients with CLL and comorbidities. Obinutuzumab was superior to rituximab in this same study in terms of response rates and progression-free survival. Several preclinical and early phase clinical studies also support the efficacy of obinutuzumab. The most frequent adverse event noted with obinutuzumab is infusion-related reactions, which occur more frequently than with rituximab and are typically restricted to the first cycle of therapy. Based on these results, obinutuzumab should be considered the gold standard mAb for combination with chemotherapy in previously untreated patients with CLL and comorbidities. The marked efficacy of obinutuzumab with a weak chemotherapy backbone implies significant potency of this mAb, making it the ideal partner for combination studies with other agents in CLL.
Orientation-Controllable ZnO Nanorod Array Using Imprinting Method for Maximum Light Utilization in Dye-Sensitized Solar Cells
Authors: Jeong Huisu , Song Hui , Lee Ryeri , Pak Yusin , Kumaresan Yogeenth , Lee Heon , Jung Gun Young
Published: June 2015

We present a holey titanium dioxide (TiO2) film combined with a periodically aligned ZnO nanorod layer (ZNL) for maximum light utilization in dye-sensitized solar cells (DSCs). Both the holey TiO2 film and the ZNL were simultaneously fabricated by imprint technique with a mold having vertically aligned ZnO nanorod (NR) array, which was transferred to the TiO2 film after imprinting. The orientation of the transferred ZNL such as laid, tilted, and standing ZnO NRs was dependent on the pitch and height of the ZnO NRs of the mold. The photoanode composed of the holey TiO2 film with the ZNL synergistically utilized the sunlight due to enhanced light scattering and absorption. The best power conversion efficiency of 8.5 % was achieved from the DSC with the standing ZNL, which represented a 33 % improvement compared to the reference cell with a planar TiO2.
Existence and convergence theorems of fixed points for multi-valued SCC-, SKC-, KSC-, SCS- and C-type mappings in hyperbolic spaces
Authors: Chang Shih-sen , Agarwal Ravi P , Wang Lin
Published: June 2015

The purpose of this paper is to introduce the concepts of multi-valued SCC-, SKC-, KSC-, SCS- and C-type mappings and propose a classical Kuhfitting-type iteration (Kuhfitting in Pac. J. Math. 97(1):137-139, 1981) for finding a common fixed point of the SKC-, KSC-, SCS- and C-type multi-valued mappings in the setting of hyperbolic spaces. Under suitable conditions some Δ-convergence theorems and strong convergence theorems for the iterative sequence generated by the proposed scheme to approximate a common fixed point of a finite family of SKC-, KSC-, SCS- and C-type multi-valued mappings are proved. The results presented in the paper extend and improve some recent results announced in the current literature.
On spatial modelling
Authors: Tchertov Leonid
Published: June 2015

Spatial modelling concerns both the case when spatial structures have a modelling function and the case when such structures become modelled objects. In the article, spatial models are considered as the means of human activity in both external and internal aspects. External spatial models are tangible objects which have structural similarity with something different from them and can represent it for a subject. These external models can be interpreted on various mental levels: sensorial, perceptual, apperceptual and conceptual ones. Each of them is connected with a peculiar way of internal modelling. Both external and internal spatial models can have a productive or a reproductive character, which depends on whether they serve as patterns for reproduction or if they are copies of originals. It is possible to consider external models as spatial texts if they can be divided into a plane of expression and a plane of content which are connected with each other by a semiotic system. In particular, such division can be revealed in depictions in which the two planes of both depicting and depicted spaces are open for the eye and their connection is regulated by indexes of a special perceptographic code. So, depictions can be treated as spatial texts interpreted firstly on the perceptual level of internal modelling and, secondly, on the higher mental levels by means of other visual-spatial codes.The article is divided into three parts. The first part contains a description of the basic concepts introduced in the author’s interpretation. In the second part, these concepts are applied to description of spatial modelling and its semiotic means. In the third part an important special case of spatial modelling – combination of mimetic and semiotic means in formation of depictions – is discussed.

Published: June 2015

The authors have identified priority units – target neuroprotective therapy aimed at restoring the ratio NO/glutathione restored. For this purpose, animals with acute cerebral blood flow (stroke) were injected modulator selenium-dependent glutathione peroxidase medicament "Selenaza" in various doses. In the experiment, the authors used the model of bilateral occlusion of the common carotid arteries – by type of ischemic stroke to Wistar rats. It has been shown that the administration of different dosages "Selenaza" significantly reduces stress marker nitrosating stress - nitrotyrosine, improves the reduced glutathione and glutathione peroxidase enzyme, modifies thiol-disulfide equilibrium in the direction of its reduced forms. According to effect – dose dependence, the concentrations of sodium selenite were calculated ED50 drug "Selenaza", it was 50 ug/ml.

Conclusions: These results suggest that selenium protects neurons against hypoxic/ischemic damage by reducing oxidative stress, restoring mitochondrial functional activities, as well as increase levels of reduced glutathione and glutathione peroxidase and reduce markers of nitrosating stress- nitrotyrosine.

To evaluate the effectiveness of treatment modalities in regenerative medicine is proposed to calculate the parameters of the center of quasi-attractors and the amount of change of the volume Vx. Knowing the duration of the therapeutic effects of T can determine the average velocity ν motion for quasi-attractor in phase space coordinates xi and largest relative change in the volume ν = (V2/V1)/T for the period of exposure to T. Examples of such kinematic changes in the short version (one-time fee for the period one procedure T = 40 min.) and prolonged exposure (rate of treatment Δt = 30 days). These two quantities are of diagnostic value in describing the features of the disease and the nature of thera-peutic effects on the patient. Assesses of effectiveness of the treatment on the basis of the rate of change of parameters quasi-attractors in the phase space of states are given.

La comarca del Baix Vinalopó, cuya capital es la dinámica ciudad de Elche, ha experimentado cambios muy intensos durante los últimos treinta años. Aquí se analiza su población, cuya dinámica y estructura sociodemográfica son reflejo de la economía industrial de la comarca, polo de atración de una voluminosa inmigración, joven y natalista; entre 1960 y 1975 su población alcanzó las mayores tasas de crecimiento del País Valenciano. La crisis industrial posterior a 1975 corta totalmente la inmigración neta. El segundo tema tratado es la defensa del medio ambiente en los espacios litorales, pues el Baix Vinalopó tiene un rico y variado patrimonio de importancia internacional (dunas y playas; zonas húmedas litorales), que soportan una fuerte presión humana.

Expansión y crisis de la actividad pesquera valenciana en el siglo XIX
Authors: Viruela Martínez Rafael
Published: June 2015

En el siglo XIX la pesca valenciana tenía muy poca importancia en el conjunto español. A la escasa riqueza piscícola del Mediterráneo hay que añadir el uso de aparejos fruto, más que nada, de una tecnología empírica y tradicional. Las innovaciones se introdujeron con timidez y con cierto retraso con respecto al Atlántico. Probablemente la pesca experimentó un desarrollo en las primeras décadas del siglo, pero de lo que no cabe la menor duda es que desde mediados de la centuria el sector pesquero quedó sumido en una profunda crisis. Las estadísticas disponibles indican una ligera recuperación de la producción a finales del ochocientos. En aquellos momentos la distribución de los desembarcos era muy irregular, con una mayor concentración en el litoral meridional.

Su propia génesis histórica ha sido causa fundamental de esta peculiar evolución dinámica del territorio y su poblamiento. De todas maneras el proceso tan acusado de su redistribución poblacional dista de haberse acabado por el momento. En este artículo se analizan y muestran algunas reflexiones sobre ese asunto. Se apuntan cuáles son las principales tendencias seguidas durante los últimos decenios, así como los cambios regionales más notables sucedidos. Además, por supuesto, junto al análisis de los hechos interesa indagar acerca de las causas que los motivan. Tal vez, eso permite, sino avizorar el futuro, al menos intuir cuáles son los presumibles comportamientos inmediatos.

Las infraestructuras han jugado un papel relevante desde el punto de vista de la planificación territorial al ser un elemento clave en la estructuración del espacio y al actuar como principio que fomenta el desarrollo de unas regiones y el desenclave de otras. Aspectos potenciados por las instalaciones aeroportuarias dada su función suprarregional. Tendencia evidenciados por el análisis del aeropuerto de Venecia, cuya área de influencia tradicional (regiones del Véneto, Trentino-Alto Adige y Friuli-Venezia-Giulia) es uno de los espacios más dinámicos de la península itálica. No obstante, presenta una serie de disfuncionalidades, consecuencia de su rápido crecimiento, que tratan de ser paliadas tanto por las autoridades regionales, tal y como se recoge en el Piano Territoriale Regionale di Coordinamente (Plan Territorial Regional de Coordinación) como por el ente encargado de su gestión, que ha elaborado el Piano Aeroportuale Generale (Plan aeroportuario). Estudio que pretende ser una apuesta de futuro.

Los corredores naturales de Almansa y Valle del Vinalopó se han beneficiado históricamente de una ubicación estratégica que ha potenciado su temprano desarrollo industrial. Hasta mediados de la centuria actual, este nexo de comunicaciones se vio favorecido por ser pieza clave en el eje Madrid-litoral. Hoy día suma tal renta de situación a la de seguir siendo cauce destacado en el nuevo marco de las relaciones norte-sur sobre la euro-región mediterránea. En ese ámbito concreto, se analiza el transporte de mercancías que generan o demandan las empresas de los principales subsectores productivos, con una escala intrarregional.
