The Extraordinary History of The Musicological Collection of Philipp Spitta
Dynamika systematycznego wzrostu, nowoczesna przestrzeń intelektu, labirynt znaków, magia zaangażowanych w swoją pracę ludzi z pasją – to tylko kilka haseł, które przychodzą na myśl, kiedy chcemy przywołać nazwę Biblioteki Uniwersytetu Łódzkiego i 70 lat jej historii. Łódź przed dwoma wiekami powstawała z tradycji niejednorodnych, i podobnie powstawał – jako mozaika różnych treści intelektualnych – Uniwersytet Łódzki.The article presents the most important information on Philipp Spitta as well as the extraordinary history of his private musicological collection located in The Special Collection Department.
Philipp Spitta (1841–1894) was a German musicologist, a friend of Schumann and Brahms, a prominent expert on the life, and music of Johann Sebastian Bach and the famous author of his monography. During his life Ph. Spitta collected monuscripts, printed music and books from the XVI century.
During World War II, the collection, containing about 4000 works, was scattered. One part found its place in the Library of the Universität der Künste in Berlin, another one – in the The Library of Łódź University.
In this article, various problems concerning the discovery, the arrangement, and the presentation of this collection in the Library, are described. The cooperation with the German side is also mentioned, as a result of which appeared the combined catalogue covering the whole collection
Rola bakterii endofitycznych w fitoremediacji gleb skażonych związkami ropopochodnymi
Recent attention has been paid to the endophytic bacteria which live inside plant
tissues without causing any apparent symptoms of diseases. These bacteria display a broad
range of symbiotic interactions with their host. Several studies demonstrated that endophytes
may significantly increase effectiveness of phytoremediation of soils polluted by petroleum
hydrocarbons. The highest potential have hydrocarbon-degrading endophytic bacteria with
multiple plant growth-promoting mechanisms and ability to survive in contaminated soil and
to colonize plant tissues.
The aims of this study were to isolate and characterise crude oil-degrading
endophytic bacteria from different tissues of the birdsfoot trefoil (Lotus corniculatus),
evening primrose (Oenothera biennis) and tall hawkweed (Hieracium piloselloides). These
plants were collected in the highly-polluted area around the refinery in Czechowice-
Dziedzice. The diversity and richness of microbiome of birdsfoot trefoil and tall hawkweed
were assessed by 454 pyrosequencing. Furthermore, the biochemical traits considered as plant
growth-promoting mechanisms of endophytes and their ability to grow on media containing
crude oil, diesel oil, n-hexadecane, as sole carbon sources were evaluated. The selected strains
were used as inoculum in the phytoremediation experiment.
Based on morphological characteristics, in total 44 crude oil-degrading endophytic
bacteria were isolated from the interior tissues of three plants. The isolates possessed
numerous mechanisms supporting plant growth, which allowed them to be included in the
group of plant growth promoting endophytes (PGPE). All selected endophytes synthetized
indole-3-acetic acid (IAA) at varying levels, and most of them had the ability to produce
cellulolytic enzymes (> 40%). More than 80% of endophytes were found to be motile. PCR
analyses revealed that catabolic genes that are associated with hydrocarbon degradation
pathways were widespread in the tested strains. The isolates were identified based on
sequencing of their 16S rDNA genes. Gammaproteobacteria comprised the majority of the
isolated strains and were the predominant group in the investigated plant species. Bacterial
isolates belonging to the genus Rhizobium and Rhodococcus were the most abundant in the
tissues of O. biennis. Pseudomonas sp. was the most often isolated from L. corniculatus and
H. piloselloides.
The metagenomics analysis showed that Proteobacteria, Actinobacteria and
Firmicutes were the most abundant phyla in all samples. The highest bacterial diversity was revealed in roots of H. piloselloides, while the lowest diversity was observed in roots of L.
corniculatus. The predominance of Alphaproteobacteria was driven by the high abundance of
mentioned phyla.
The impact of endophytic bacteria Rhodococcus erythropolis 5WK and Rhizobium
sp. 10WK on petroleum hydrocarbons removal efficiency during phytoremediation with
Lolium perenne was evaluated. In the phytoremediation experiment, two inoculation
techniques: (1) soil inoculation (SI); (2) seeds pre-inoculation followed by soil inoculation
(PI), were used. After 75 days of phytoremediation, the highest TPH removal (19.1%). was
observed in the soil, where a consortium of strains and seed pre-inoculation method with soil
inoculation (PI+5WK+10WK) were used. Multivariate statistical analysis showed that the
method of strains inoculation significantly affected TPH removal and biomass production.
Both strains were able to colonize the soil and interior plant tissues (roots and shoots), and
their introduction into the soil caused only short-term changes in the total number and
abundance of aliphatic hydrocarbon-degrading autochthonous microbial community in soil.
Presented results have a high cognitive, scientific and potentially practical
significance. Characterised endophytic bacteria may be useful in further research of both a
basic and practical nature, on bioremediation and phytoremediation of soils contaminated
with petroleum hydrocarbons. In addition, results obtained in this project allowed to
complement the knowledge about the abundance and biodiversity of the endophytic bacteria
associated with plants growing spontaneously on heavily polluted environment
Aktywistyczna neuroestetyka Warrena Neidicha jako metoda krytycznej analizy mechanizmów neurokognitywnego kapitalizmu
Tematem artykułu jest działalność twórcza i kuratorska Warrena Neidicha oraz analiza proponowanego przez niego projektu aktywistycznej neuroestetyki. W 1996 roku Neidich i Nathalie Anglès założyli platformę artbrain.org, internetowe czasopismo „Journal of Neuroaesthetics” oraz galerię Chaoid. Dwadzieścia pięć lat później Neidich wraz z Susanne Prinz i Sarritą Hunn zorganizowali cykl wydarzeń pod deklaratywnym hasłem „Activist Neuroaesthetics”. Stało się to inspiracją do podjęcia dyskusji o artystycznych implikacjach neurokognitywnego kapitalizmu oraz o możliwościach prowadzenia interdyscyplinarnych badań na gruncie estetyki empirycznej.
Tekst jest rozwinięciem myśli podjętej w ramach panelu konferencyjnego „Współczesne kulturoznawstwo medialne – nowe strategie, praktyki, artykulacje, pola i metody badań”, który odbył się w ramach IV Zjazdu Polskiego Towarzystwa Kulturoznawczego
Atypowy rozwój mózgu jako zaburzenie wpływające dysfunkcyjnie na rozwój psychomotoryczny i społeczny dziecka - ujęcie interdyscyplinarne
Atypical brain development is a term that can be used to address the full range of developmental
disorders that are found to be overlapping much of the time in any sample of children. The
authors present ideas that are, in part, a response to the neurodevelopmental disorders and psychomotor, social and speech disorder in children
Wczesna stymulacja dzieci z podejrzeniem atypowego rozwoju mózgu : studium przypadku
The article presents and emphasises any early actions and planned activities taken to support
the development of children who are in the early stages of development visible symptoms of atypical
brain development (ABD). The methods and forms of early therapeutic intervention and its impact
on children’s development are discussed on the selected case studies. It should be pointed out that the
need for multidisciplinary diagnosis of children and then the consequences of the lack of specialised
holistic therapy, which should be implemented are also indicated in the article. What is more, the article
presents a proposal for “Therapeutic work program for children with ABD”, containing physical development,
visual perception and spatial orientation, speech and thinking development and improvement
of reading skills. The above-mentioned program is a good example of supporting the early development
of children from infancy period till a primary school period
Hydrocarbon degradation potential and plant growth-promoting activity of culturable endophytic bacteria of Lotus corniculatus and Oenothera biennis from a long-term polluted site
Many endophytic bacteria exert beneficial effects on their host, but still little is known about the bacteria associated with plants growing in areas heavily polluted by hydrocarbons. The aim of the study was characterization of culturable hydrocarbon-degrading endophytic bacteria associated with Lotus corniculatus L. and Oenothera biennis L. collected in long-term petroleum hydrocarbon-polluted site using culture-dependent and molecular approaches. A total of 26 hydrocarbon-degrading endophytes from these plants were isolated. Phylogenetic analyses classified the isolates into the phyla Proteobacteria and Actinobacteria. The majority of strains belonged to the genera Rhizobium, Pseudomonas, Stenotrophomonas, and Rhodococcus. More than 90% of the isolates could grow on medium with diesel oil, approximately 20% could use n-hexadecane as a sole carbon and energy source. PCR analysis revealed that 40% of the isolates possessed the P450 gene encoding for cytochrome P450-type alkane hydroxylase (CYP153). In in vitro tests, all endophytic strains demonstrated a wide range of plant growth-promoting traits such as production of indole-3-acetic acid, hydrogen cyanide, siderophores, and phosphate solubilization. More than 40% of the bacteria carried the gene encoding for the 1-aminocyclopropane-1-carboxylic acid deaminase (acdS). Our study shows that the diversity of endophytic bacterial communities in tested plants was different. The results revealed also that the investigated plants were colonized by endophytic bacteria possessing plant growth-promoting features and a clear potential to degrade hydrocarbons. The properties of isolated endophytes indicate that they have the high potential to improve phytoremediation of petroleum hydrocarbon-polluted soils
Severe injuries of the pancreas and duodenum
Obrażenia trzustki i dwunastnicy występują rzadko ze względu na ich zaotrzewnowe umiejscowienie.
W większości uszkodzenia tych narządów są następstwem tępych urazów brzucha. Przedstawiane w niniejszej
pracy przypadki urazów trzustki i dwunastnicy stanowiły trudny problem diagnostyczny, a ostateczny
zakres uszkodzeń ustalono dopiero podczas laparotomii.Injuries of the pancreas and duodenum are relatively uncommon by virtue of their retroperitoneal location.
Lesions are, in the majority, due to blunt abdominal trauma. The cases of pancreatic and duodenal
injuries presented in our study posed a difficult diagnostic problem and it was not until a laparotomy was
performed that the final range of injuries was determined
The relationship between total body fat and distribution of body fat mass and markers of insulin resistance in young women with normal weight — a pilot study
Introduction. Total body fat and body fat distributionare factors closely associated with development ofinsulin resistance, including subjects with normal bodyweight and BMI (body mass index).
Objectives. The objective of the study was to determinerelation between insulin resistance index and selectedparameters of body fat distribution in potentiallyhealthy young females with body mass index below25 kg/m2.
Material and methods. Study group consisted of 36women with a BMI < 25 kg/m2, who underwent anthropometricmeasurements, i.e.: height, weight, waistcircumference, hip circumference and blood pressuremeasurement. The segmental body composition wasmeasured by of the use of the bioelectric impedanceanalysis (BIA). Moreover, oral glucose tolerance test(OGTT) was performed with blood collection in 0, 60and 120 minute of the test. The fasting samples wereused for determination of concentrations of glucose,insulin, C-peptide, a total cholesterol, triglycerides, HDLand LDL cholesterol. The following insulin resistanceindices were calculated: HOMA-IR, HOMA2-IR, HOMA2-%B, HOMA2-%S and IRI/G.
Results. All the volunteers presented normal glucosetolerance in 120 minute of the OGTT test, as well asnormal values of IRI/G index. Moreover, for such parametersas: total cholesterol, HDL and LDL cholesterol,triglycerides and CRP no values outside the referencerange were found. C-peptide concentration was foundto be significantly correlated with total body fat(r = 0.532; p = 0.001) and trunk fat mass (r = 0.471;p = 0.004).
Conclusions. In the young, non-obese women it seemsto be justified to test concentration of glucose andC-peptide while assessing potential insulin resistancewith simultaneous examination of the total and trunkbody fat
