Polnische Bibliothek
Authors: Zajas Paweł
Published: March 2020

ThePolnische Bibliothek,founded by the German Institute for Polish Culture in Darmstadt, financed by Robert Bosch Foundation and published by the Suhrkamp Publishing House, remains a unique attempt at presenting Polish literature in the German book market. This paper focuses on the historical, political and cultural background of the series and the conflicts at the backstage of its initiation. The analysis, based mostly on the so far unpublished archival correspondence of the publishing house has two aims: on the one hand, a historiographic description of the so far unknown processes of Polish literature transfer lies at its centre, on the other, it addresses the need for appropriate conceptualisations of such phenomena. The study is framed in the category ofHistoire croiséein this case applied to an analysis of translation production. Activities of all the actors involved, the conflicts and solutions to them constitute the starting point. These generate an argumentation space which offers insights into the history of production of the series that had since its beginning been marked by conflicting expectations.
Carlo Antonio and the bottega Procaccini
Authors: Conte Angelo Lo
Published: March 2020

This study investigates the career of Carlo Antonio Procaccini, a member of one of the most prominent artistic families of the early Italian Seicento. Together with his brothers Camillo and Giulio Cesare, he was instrumental in establishing a famous workshop in Milan which played a fundamental role in the artistic renovation of the Borromean era. Celebrated by seventeenthcentury sources, Carlo Antonio’s career has been largely underestimated. The essay reaffirms his legacy as the most important North Italian landscape painter of the first three decades of the seventeenth century, highlighting how his art thrived in the uniqueness of the Milanese artistic environment, which was characterized by post-Tridentine reform and prosperity, Spanish patrons, and Northern European connections as well as artistic eclecticism.
Translating images from India to Amsterdam in the eighteenth century

This article examines the physical interface of print and its role in translating beliefs not informed by a western theology of the imprint. A close reading of Jean Frédéric Bernard and Bernard Picart’s Cérémonies et coutumes religieuses (1723– 1743), with a focus on the section on religious practices in India, demonstrates the limitations of western typography and engraving in translating cultures formed outside of a material and physical history of the printed word and image.
Das Thema Männlichkeit im hochschuldidaktischen Verwendungszusammenhang – am Beispiel der theologischen Lehre im Fachbereich Neues Testament
Authors: Smit Peter-Ben
Published: March 2020

Gender ist ein wichtiges Thema in der theologischen Lehre, auch in Hochschulen. Dabei werden die Geschlechterkonstruktionen von „Männlichkeit“ häufig wenig berücksichtigt, obwohl sie großen Einfluss haben. So zeigt dieser Beitrag auf, wie Konstruktionen von „Männlichkeit“ in einem Teilbereich der Theologie, nämlich der neutestamentlichen Wissenschaft, eine bedeutsame Rolle spielen (können) und wie dies, gerade auch in der Auseinandersetzung mit Studierenden, denen diese Thematik eher fremd ist, zu einem produktiven Thema im Seminarraum gemacht werden kann, ohne dabei problematische Machtverhältnisse zu (re)produzieren.

Authors: Sunar Baskoro Ario , Milyardi Indra , Amat Mohammad Azwar
Published: March 2020

In this paper, an autogenous tungsten inert gas (TIG) welding was performed to understand the characteristic effect of butt joint weld on AA1100 under various parameters. The effect of TIG current and welding speed was selected to study the mechanical properties, porosity, and macrostructure of the weld metal (WM). Based on experimental results, the top bead width (TBW) will increase directly proportional to the increased of welding current. Furthermore, welding current and welding speed affected the strength drop in the heat-affected zone (HAZ). More heat added will result in a deeper drop in strength. Mechanical properties result showed that the tensile strength reduced by 40 – 45% and the hardness reduction in the WM and HAZ area from the base metal (BM) was 17.3% and 27.7%, respectively. Subsequently, X-Ray radiography images showed that there was no large porosity occur in all welding current. The macrostructure showed that the weld bead typically has the concavity shape or U-shaped geometry from a cross-sectional view.

Authors: Chandrabakty S. , Renreng I. , Djafar Z. , Arsyad H.
Published: March 2020

One of the machining failures in composite materials is delamination damage. In this paper, machining parameters and delamination damage caused by the drilling process on ramie woven reinforced composite material with an unsaturated polyester matrix were investigated. The ramie woven used is ramie yarn type 12S/3. The machining process used 1.5 kW Pillar drills, where variations in the diameter of the "brad & spur" drill are 4 mm, 6 mm, 8 mm, and 10 mm, respectively. In this work, focuses on the influence of machining parameters like feeds rate and spindle speed. Holes quality was analyzed in terms of thrust force and delamination failure. From the results of this study, the thrust force value obtained at the time of drilling is very closely related to the delamination damage that happens. Delamination damage occurs on both sides of the holes drill.

Published: March 2020

Nanofluids are used in heat exchanger system as efficient heat transfer fluids to improve heat transfer performance by passive method. Besides, another special active technique by implementing the low or high frequency vibration, which was used in heat exchanger to enhance the heat transfer performance. This paper reviews the heat transfer augmentation in heat exchanger by using nanofluids, vibration excitation of low and high frequency vibration. The use of nanofluids in heat exchanger system can provide better effective thermal conductivity compared to the conventional coolants. The presence of nanosize particles in nanofluids performed better mixing flow with higher thermal properties compared to pure fluids. Additionally, the active method by inducing low and high frequency vibration technology was applied in heat exchanger system. The heat transfer augmentation by vibration excitation was resulted from the mitigation of the fouling resistance on the surface of the tube wall. It was found that vibration excitation not only increase the heat transfer rate, but also might be a solution for fouling reduction. Hence, there is a great potential of using nanofluids together with vibration excitation simultaneously in heat exchanger system to improve the heat transfer performance.

Published: March 2020

Este artículo muestra los resultados del proyecto de investigación/intervención, denominado “Significados y Sentidos del amor en parejas con historias de infidelidad”, realizado en la Universidad Santo Tomas de Bogotá (Colombia). Se realizó una apuesta por la comprensión de los significados del amor en parejas que han tenido engaños y desilusiones amorosas asociadas a infidelidades, y la intervención psicoterapéutica para la reorganización de versiones novedosas del amor, la infidelidad y el ser pareja desde una perspectiva sistémica constructivista, socio construccionista y compleja. En esta investigación, participaron dos parejas cuyo motivo de consulta se relaciona con la infidelidad, se desarrollaron 5 escenarios narrativos conversacionales con cada una de ellas, empleando dispositivos de intervención tales como: la construcción de historias, las esculturas y las metáforas. Los principales hallazgos reconocen relatos matizados de los conyugues, por imágenes idealizadas de la pareja generando sentimientos de culpabilidad, historias asociadas al silencio y sometimiento como forma de solucionar los conflictos, la deconstrucción de historias de infidelidad para reconstruir la trama narrativa de la pareja desde aspectos particulares que conectan a los enamorados, y el acontecimiento de infidelidad como posibilidad de cambio.

Impact of soil use on aggregate stability and its relationship with soil organic carbon at two different altitudes in the Colombian Andes
Authors: Visconti-Moreno Efraín Francisco , Valenzuela-Balcázar Ibonne Geaneth
Published: March 2020

The stability of soil aggregates depends on the organic matter, and the soil use and management can affect the soil organicmatter (SOM) content. Therefore, it is necessary to know therelationship between aggregate stability and the content of SOMin different types of soil use at two different altitudes of theColombian Andes. This study examined the conditions of soilaggregate stability expressed as a distribution of the size classes of stable aggregates (SA) and of the mean weighted diameter of the stable aggregates (MWD). To correlate these characteristics with the soil organic carbon (OC), we measured the particulate organic matter pool (POC), the OC associated with the mineral organic matter pool (HOC), the total organic carbon content (TOC), and the humification rate (HR). Soils were sampled at two altitudes: 1) Humic Dystrudepts in a cold tropical climate (CC) with three plots: tropical mountain rainforest, pastures, and crops; 2) Fluvaquentic Dystrudepts in a warm tropical climate (WC) with three plots: tropical rainforest, an association of oil palm and pastures, and irrigated rice. Soils were sampled at three depths: 0-5, 5-10 and 10-20 cm. The physical properties, mineral particle size distribution, and bulk density were measured. The content of SA with size>2.36 mm was higher in the CC soil (51.48%) than in the WC soil (9.23%). The SA with size 1.18-2.36 mm was also higher in the CC soil (7.78%) than in the WC soil (0.62%). The SA with size 0.60-1.18 mm resulted indifferent. The SA with size between 0.30 and 0.60 mm were higher in the WC soil (13.95%) than in the CC soil (4.67%). The SA<0.30 mm was higher in the WC soil (72.56%) than in the CC soil (32.15%). It was observed that MWD and the SA>2.36 mm increased linearly with a higher POC, but decreased linearly with a higher HR. For the SA<0.30 mm, a linear decrease was observed at a higher POC, while it increased at a higher HR.

Published: March 2020

Diseases and disorders are one of the main limitations ofavocado crops for export and national markets. However, theyare poorly studied in tropical countries such as Colombia. Theobjective of this research was to evaluate a polyphasic approachfor the diagnosis of pathologies and disorders associated withavocado cv. Hass in nurseries and crop fields located in Antioquia, Colombia. Results allowed the identification of several diseases and disorders present on different tissues in all stages of plant development. The root rot disease was associated with 10 microorganisms and two abiotic disorders. Different organs and tissues of avocado plants were affected by pathogens such as Lasiodiplodia theobromae, Colletotrichum gloeosporioides sensu lato, and Phytophthora palmivora. Pathogens that had not been previously reported in Colombia were identified, and among them P. palmivora, Fusarium oxysporum sensu lato, Phytopythium vexans, Phomopsis sp., and Pythium cucurbitacearum stand out. Abiotic disorders such as hypoxiaanoxia, root atrophy, fruit sunburn, and hailstorm damage were also identified. The etiology of peduncle ringing was not identified. Polyphasic diagnosis of pathologies and disorders is an appropriate approach as part of an integrated disease management program in avocado cv. Hass crop. This work is a reference tool on basic aspects associated with the detection of disorders and pathologies in avocado and the taxonomy of the microorganisms involved.

Published: March 2020

The article examines the current tendencies of entering the oil and fat subcomplex of Ukraine intothe world markets. It has been revealed that oil crops and their products are the main export commodity inagro-food export of the state. The large scale production of the sub-complex products, with modest domesticconsumption, is first and foremost associated with successful integration into international trade. Foreigntrade thus becomes an important factor in the development of the subcomplex. Considering the complexityand multidimensionality of the problem, the main segments of the market - oilseeds, oils and oilcake - arehighlighted in the research. On the basis of statistical data, the analysis of export volumes, dynamics, position on the world market and opportunities for their strengthening were made. It has been established thatUkraine, as a powerful producer and active participant in the world market, influences, to some extent, theexcess of world production over consumption of oil and products of their processing, which leads to a decrease in export prices and, as a consequence, to a loss of export earnings of domestic exporters. The studysubstantiates the need to improve the structure of production of oilseeds, the balance of use of soybeansand rapeseed, constant monitoring of the situation in foreign markets.

The pecan nut is produced in 57 countries in the world. Alternate bearing is one of the main biological problems that affect pecan cultivation. Mineral and organic fertilization is a good strategy to maintain and increase pecan nut production. In this study, several mineral and organic doses of fertilization were tested using a factorial arrangement 56 bounded to 25 treatments was used in structure Taguchi L25: nitrogen (N) 0 - 240 kg ha-1, phosphate (P2O5) 0 - 120 kg ha-1, potassium (K2O) 0 - 100 kg ha-1, calcium (CaO) 0 - 400 kg ha-1, liquid humus 0 - 3600 L ha-1 and solid humus 0 - 8000 kg ha-1. The study was carried out in Aldama city, Chihuahua (Mexico). An average yield of 2.4 t ha-1 was obtained, 157 nuts per kilogram and 58.9% of edible nut. The average alternate bearing intensity was 31.58%, and the long-term yield index (IRLP) was 9.59%. It is concluded that the factors whit the greatest impact on the analyzed variables were N and P2O5. In addition, it was found these mineral and organic fertilization systems help to reduce alternate bearing in pecan and simultaneously improve production and long-term productivity index. Optimal fertilization doses were defined: 181.4 kg ha-1 of N, 93.5 kg ha-1 of P2O5 and 3287.2 L ha-1 of liquid humus. Finally, the mineral fertilization complemented with organic fertilization is considered a good fertilization strategy for pecan trees, to increase production and with lower environmental impact.

Published: March 2020

Tomato (Solanum lycopersicum L.) is the most produced and exported vegetable in Turkey. There are many pathogens to limit tomato production by reducing yield and fruit quality. Among them, Tomato Yellow Leaf Curl Virus (TYLCV) causes important economic losses. The most efficient and environmentally friendly method against TYLCV is the use of resistant varieties. In this trial, it was aimed to determine some morphological traits which were linked to Ty-1 and Ty-3a genes which confer to TYLCV. A commercial hybrid carrying Ty-1, Ty-3a genes as heterozygous was crossed to a susceptible inbred line from Bati Akdeniz Agricultural and Research Institute (BATEM). Marker assisted selection (MAS) was carried out in F1 and F2 generations and biological tests were done for TYLCV resistance in F3 generation. MAS for Ty-3a and Ty-1 genes were compatible with biological tests. In total of 95 genotypes in F3 were developed with molecular marker selection. It was determined that 30 genotypes having the Ty-3a and Ty-1 genes as homozygous resistant. The nine genotypes carried these genes in heterozygous form. 56 genotypes were identified as susceptible. The 43 morphological traits were observed in identified individuals to correlate with resistant allele, Ty-3a. It was found that there was statistically important correlation between Ty-3a and length of internode, length of stem at first inflorescence, status of calix, leaf attitude, length of inflorescence and plant habitus. Also, there was negative correlation between fruit weight, fruit length and resistance. Therefore, we identified some morphological markers linked to Ty-3a which can be used in selection for TLYCV resistant breeding programme.

Published: March 2020

Female cervical cancer is largely formed by Human papillomavirus (HPV), the second leading cause of cancer deaths in women worldwide. HPV-52 is a regionally common high-risk type of cervical cancer found mostly in Asia and reveals geographical variations, in order of importance, as types HPV-16 and -18. However, the differing propensities of HPV types in progressing to cancer, focusing on HPV-52 vaccines, are limited. Several plant-based vaccines against cancer have been developed, and the production of candidate HPV therapeutic vaccines using plant-derived expression platforms is also proven. The objectives of this study were to assess the HPV-52L1 Capsid gene by transferring HPV-52L1 Capsid cDNA into rice (Oryza sativa L.) via an Agrobacterium-mediated transformation, and accumulating HPV-52L1 Capsid proteins in a plant-based expression system to maintain and improve antigenicity. Crude protein extracts containing 5~20 μg from OsHP-52L1 transgenic lines induced cell death and significantly reduced cell proliferation in HPV-positive HeLa cervical cancer cells compared with those non-transformant (NT) rice plants. However, no significant cytotoxicity of induced human breast MDA-MB-231 cell proliferation (as negative control) was observed at any dose compared with NT groups. HeLa cells ameliorated the effects of OsHPV crude protein extracts on cell viability as the extract concentration increased, and treatment with 20 μg of the extract from OsHPV-3 significantly reduced cell viability in HeLa cells (26%) compared with the control group (57%). Our results can be used for exploring the potential of plants for increasing the immunogenicity of OsHPV-52L1 Capsid DNA vaccines, and support the development of cost-effective HPV vaccines, which is highly desirable for resource-poor countries.
The effect of cultivar and harvesting stage on the chemical composition of processing tomato fruit
Authors: GAWĘDA Maria , JĘDRSZCZYK Elżbieta
Published: March 2020

Field-grown processing tomatoes are harvested in the red stage, however a significant part of fruits remaining on the crop are at the turning stage and in the mature-green stage. This is a part of the crop that can still be used after post-harvest ripening. The aim of the study was to compare the quality of the three determinate tomato cultivars harvested in the field during the red stage with that of red tomatoes obtained after ripening on shelf (harvested in the turning and mature-green stages). Red fruits were analysed immediately after harvest. The remaining fruits were stored and analysed after they had reached the red stage. Experiment showed that unripe tomatoes harvested in mature green phase during shelf ripening can achieve a good fruit quality, comparable to those harvested red. There was found no impact of the degree of ripeness at harvest on the content of dry matter. The relationship between content of extract, soluble sugars and organic acids and the degree of ripeness at harvest depended on the vegetation period. In 2009 fruits harvested green or pink reached higher content of extract, soluble sugars and organic acids than fruits harvested red. In 2010 it was quite contrary; all parameters were worst in fruits collected green or pink. In 2011 there were no differences in extract, whereas level of sugars and organic acids were higher in fruits collected unripe, stored and analysed after they had reached the red stage. Regardless of the year of research, vitamin C level was always the highest in the fruits collected red.

Experiments were conducted on valerian (Valeriana officinalis L.) grown under glasshouse conditions to evaluate the effect of Cadmium (Cd) on plant morphological characteristics and Cd uptake. Valerian plants were grown in pots containing a uniform mixture of either moderately acidic or slightly alkaline substrate consisting of peat and perlite (1:1 v/v) over two periods. Pots were arranged in a completely randomized block design within two groups (moderately acid substrate and slightly alkaline substrate) with four Cd treatments (0, 1, 2 and 5 mg Cd L-1) and six replications per treatment. Cadmium was applied as CdSO4*8/3H2O. No visual symptoms of toxicity or nutrient deficiency were attributed to Cd application irrespective of the growth stage or substrate in either experimental period. Cadmium did not affect the dry mass of shoots or roots. Cd concentration in both shoots and roots increased with increasing Cd application, indicating valerian to be a Cd accumulator with accumulation occurring mainly in the roots both in moderately acidic or slightly alkaline substrates. The amount of Cd extracted by Diethylene triamine penta acetic acid-triethanol amine (DTPA-TEA) increased with increasing Cd doses and significantly correlates with the Cd concentrations within the shoots and roots indicating that this extractant could be used to predict Cd concentrations within the plant parts.

The ethanol extracts of selected Acinos Miller species were investigated in terms of chemical composition, antimicrobial and antioxidative activities. Qualitative and quantitative analyses of the extracts were performed using GC and GC-MS. Eighty-six constituents, accounting for 93.70-99.99% of the total composition of the extracts, were identified. The ethanol extracts of A. majoranifolius, A. suaveolens and A. alpinus were characterized by domination of monoterpenes, representing 85.03%, 57.39% and 28.02% of the total extracts, respectively. Fatty acids and their esters in the A. arvensis and A. graveolens extracts reached 28.97% and 30.75%. Also, n-alkanes were the major compounds found in A. hungaricus ethanol extract (30.98%). The extracts were characterized by determination of total polyphenols, flavonoids and tannins. Besides, the antioxidant activity of the investigated extracts was estimated by two assays: DPPH and FRAP test. The highest antioxidant activity was observed in the extract of A. alpinus which had high levels of all examined polyphenol classes. A disk diffusion method was employed for the determination of the antimicrobial activities of the ethanol extracts. Gram-positive: Bacillus subtilis, Sarcina lutea, Staphylococcus aureus, Clostridium pyogenes, Enterococcus sp., Micrococcus flavus; Gram-negative: Klebsiella pneumoniae, Pseudomonas aerugionsa, Salmonella enteritidis, Proteus vulgaris, Escherichia coli and fungal organisms: Aspergillus niger, Candida albicans and Saccharomyces cerevisiae were used as test microorganisms. The results of preliminary bioassay demonstrated that the A. alpinus ethanol extract could be a possible source of compounds with antioxidant and antimicrobial activity.

Chickpea (Cicer arietinum L.) is one of the most important legume crops worldwide, with its importance mainly relying on its high protein content. Chickpea productivity is strictly threatened by abiotic stresses, of which drought exerts the most crucial role in terms of growth inhibition and yield losses encountered. Given that germination is a critical stage that is negatively affected by drought, the aim of this study was to estimate the genotypic variability among ten chickpea genotypes and to determine the seed germination and seedling growth ability under drought stress conditions. Seeds were subjected to water stress by polyethylene glycol (PEG-6000) at five stress levels (0, 5, 10, 20, 30 and 50% PEG). Germination percentage, seed water content, seed water absorbance, root and shoot development and seedling vigour index were evaluated. The analyses revealed significant genetic variability in relation to genotypic performance under drought stress. Drought significantly affected germination as well as all other associated traits, with the effects of stress being analogous to the stress level applied. Findings point to the fact that seedling vigour index is a suitable selection criterion for drought tolerance as it allowed the classification of genotypes as tolerant, moderately tolerant, moderately susceptible and susceptible. Taken together, the commercial varieties ‘Thiva’, ‘Keryneia’ and ‘Gavdos’ as well as the landrace ‘Lemnos’ showed an increased drought tolerance at high stress level, indicating their possible exploitation as valuable genetic material for breeding programs or for commercial use.

In the field of Agricultural University of Athens, the effects of false seedbed technique, stale seedbed, chemical and ecologically based control on weed growth and soybean yield were evaluated (2019). The experimental treatments were: normal seedbed, normal seedbed along with pre-emergence chemical control, false seedbed, stale seedbed with glyphosate and stale seedbed with pelargonic acid. In the plots of normal seedbed along with pre-emergence chemical control, pendimethalin was applied at rate of 1560 g a.i. ha-1. In the plots of stale seedbed with glyphosate, glyphosate was applied at a rate of 2160 g a.e. ha-1 and in the plots of stale seedbed with pelargonic acid, pelargonic acid was applied at a rate of 31020 g a.i. ha-1. The experiment was conducted in a randomized complete block design with three replicates. The results revealed that stale seedbed combined either with glyphosate or pelargonic acid application reduced annual weeds’ density by 94 and 95% as compared to normal seedbed. Stale seedbed along with pelargonic acid reduced the density of perennial weeds by 36, 38 and 41% as compared to the combination of normal seedbed and pre-emergence chemical control, normal seedbed and false seedbed, respectively. The application of glyphosate in stale seedbed plots was also effective against perennial weeds. It was also observed that stale seedbed along with glyphosate increased soybean seed yield by 17, 19 and 35% as compared to the combination of normal seedbed and pendimethalin application, false seedbed and normal seedbed, respectively. Beneficial were also the effects of the combination of stale seedbed and pelargonic acid not only on soybean seed yield but also on soybean protein content. Further research is needed in order to investigate the role of false and stale seedbeds as integrated weed management practices in various crops and under different soil and climatic conditions. Research is also needed to evaluate pelargonic acid for weed control in stale seedbeds since it is an eco-friendly herbicide with no restrictions for organic farming.

Amylases have wide biotechnological potentials for applications in various industries. An α-amylase-producing bacterium was isolated from deteriorating yam tubers. Molecular characterization using the 16S rRNA gene sequencing was used to confirm the identity of the bacterium as Bacillus subtilis Y25. The effect of some cultural and nutritional factors such as pH, temperature, carbon and nitrogen sources on α-amylase production from the bacterium was determined. Maximum α-amylase production was observed using starch and peptone as carbon and nitrogen sources, respectively, with an initial medium pH of 8.0 and incubation at 45 °C for 36 h. The enzyme was purified by ion exchange chromatography on CM Sepharose CL-6B. The kinetic parameters Km and Vmax of the enzyme, as well as the effect of pH, temperature, metal ions and ethylenediaminetetra acetic acid (EDTA) on the activity of the purified enzyme were studied. The specific activity of the partially purified enzyme was determined to be 15.21 Units/mg protein with a purification fold of 3.80. The molecular weight of the purified enzyme was estimated to be 58.0 kDa. The Vmax and Km values obtained with soluble starch for Bacillus subtilis Y25 α-amylase were 314.10 ± 23.30 Units/mg protein and 53.98 ± 12.03 mg/ml, respectively. The enzyme exhibited optimum activity at a temperature of 60 °C and pH 8.0. The metal ion Ca2+ had no effect on the enzyme at 20 mM concentration, whereas Na+ and Mg2+, as well as EDTA inhibited the enzyme at the same concentration. The characteristics of the α-amylase from Bacillus subtilis Y25 revealed it to be a thermostable and an alkaline metalloenzyme with potential for applications in the detergent and saccharification industries.

Stipe anatomy of seven Pteris species collected from various locations in the Southwestern Nigeria was investigated. This was with a view to identify characters of the stipe anatomy that are important in delimiting the species. Transverse sections (TS) of stipe at proximal median and distal regions were cut with the aid of a Reichert Austria sledge microtome at 10 µ thickness. Sections were stained in Safranin O for five minutes, rinsed in three successive changes of water and counterstained in Alcian blue for five minutes. The counterstained sections were rinsed in three changes of water, and then treated in serial grades of alcohol. Observation of prepared slides was made under light microscope. Based on the shape of the vascular bundles, the Pteris species fall into three categories   which are inverted Omega, V or U shapes. The adaxial grooves varied from proximal to distal regions in all the species except in P. ensiformis where it was uniform throughout the regions.

Abstract Cognitive impairment has been described in all phases of a migraine attack and interictally. However, the prevalence and phenotype of such impairment in chronic migraine (CM) have not yet been studied. Objectives: The aim of this study was to evaluate both the prevalence of the objective cognitive deficit in patients with CM and the factors underlying its etiology. Methods: 144 patients with CM and 44 age-matched patients with low-frequency episodic migraine (EM) (a maximum of 4 headache days per month) participated in this study. Neuropsychiatric characteristics were measured with the HADS Hospital Anxiety and Depression Scale. Cognitive function was assessed with the Montreal Cognitive Assessment (MoCA), Digit Symbol Substitution Test (DSST), Rey Auditory Verbal Learning Test (RAVLT), and the Perceived Deficits Questionnaire (PDQ-20). Results: Compared to EM, CM subjects demonstrated higher subjective and objective cognitive impairment across all tests. CM patients had 4 times higher odds of achieving a RAVLT score in the lower quartile range compared to EM (Odds Ratio [OR] 3.8; 95% confidence interval [95%CI] 1.5‒9.6; р=0.005). In the MoCA, CM patients demonstrated the most striking impairment in memory/delayed recall (65.3%), attention (46.5%), abstraction (30.6%), and language (27.1%). Chronic headache and level of education, but not gender, depression or anxiety, were independent predictors of cognitive impairment. Conclusions: Cognitive impairment is prevalent in the CM population during their mildest possible pain and may be caused by a central sensitization. Timely preventive treatment of EM is warranted.
