Topological traits of a cellular pattern versus growth rate anisotropy in radish roots
The topology of a cellular pattern, which means the spatial arrangement of cells, directly corresponds with cell packing, which is
crucial for tissue and organ functioning. The topological features of cells that are typically analyzed are the number of their neighbors
and the cell area. To date, the objects of most topological studies have been the growing cells of the surface tissues of plant and animal
organs. Some of these researches also provide verification of Lewis’s Law concerning the linear correlation between the number of
neighboring cells and the cell area. Our aim was to analyze the cellular topology and applicability of Lewis’s Lawto an anisotropically
growing plant organ. The object of our study was the root apex of radish. Based on the tensor description of plant organ growth, we
specified the level of anisotropy in specific zones (the root proper, the columella of the cap and the lateral parts of the cap) and in
specific types of both external (epidermis) and internal tissues (stele and ground tissue) of the apex. The strongest anisotropy occurred
in the root proper, while both zones of the cap showed an intermediate level of anisotropy of growth. Some differences in the topology
of the cellular pattern in the zones were also detected; in the root proper, six-sided cells predominated, while in the root cap columella
and in the lateral parts of the cap, most cells had five neighbors. The correlation coefficient rL between the number of neighboring
cells and the cell area was high in the apex as a whole as well as in all of the zones except the root proper and in all of the tissue types
except the ground tissue. In general, Lewis’s Law was fulfilled in the anisotropically growing radish root apex. However, the level of
the applicability (rL value) of Lewis’s Lawwas negatively correlated with the level of the anisotropy of growth, which may suggest
that in plant organs in the regions of anisotropic growth, the number of neighboring cells is less dependent on the cell size

Alterations in metabolism and metabolic enzyme function and carcinogenesis
Dr Otto H. Warburg wykład 1966 Nobliści w Lindau, Niemcy
„Rak, ponad wszystkie inne choroby ma niezliczoną ilość wtórnych przyczyn. Jednak nawet w przypadku raka istnieje tylko jedna główna przyczyna. Podsumowując w kilku słowach, główną przyczyną raka jest zastąpienie oddychania tlenowego w normalnych komórkach organizmu przez fermentację cukru…”
Wzrost i rozwój organizmu jest nieodłącznie związany z dostępnością składników odżywczych. W związku z tym wyewoluowały specyficzne mechanizmy pozwalające na koordynację tych procesów w zależności od dostępności pożywienia, co umożliwia organizmom przetrwanie w czasie głodu. Zmniejszenie zasobów energetycznych powoduje wydłużenie życia, natomiast nadmiar kalorii jest powiązany z otyłością i chorobami nowotworowymi. Na poziomie komórkowym prawidłowe, dzielące się komórki aktywują szlaki metaboliczne, umożliwiające akumulację masy i energii wykorzystywanych do syntezy DNA w celu reprodukcji. Natomiast komórki nowotworowe przeprogramowują w sposób, wydaje się, kontrolowany swój metabolizm, aby dzielić się i rozprzestrzeniać w sposób niekontrolowany. Pewne geny kodujące enzymy metaboliczne zostają wyłączone w komórkach nowotworowych, a inne ulegają zwiększonej ekspresji, powodując zmiany metaboliczne. Badania prowadzone w ostatnich latach pokazały, że niektóre enzymy procesu glikolizy, mające swoją główną funkcję w cytoplazmie, mają zdolność do przemieszczania się do jądra komórkowego, gdzie pełnią zupełnie inne niemetaboliczne funkcje, np. biorą udział w kontroli ekspresji genów. Dlatego poznanie wpływu metabolizmu na kontrolę ekspresji genów może być niezwykle istotne w zrozumieniu przyczyn nowotworzenia.Dr Otto Warburg (Nobel in 1931) in his lecture on Lindau Nobel Laureates Meeting in 1966, Germany, stated:
“Cancer, above all other diseases, has countless secondary causes… But, even for cancer, there is only one prime cause. To summarise in a few words, the prime cause of cancer is the replacement of the respiration of oxygen in normal body cells by a fermentation of sugar…”
Growth and development of organisms are strictly dependent from availability of nutrients. Evolved specific mechanisms controlling those processes can help organisms to survive starvation. Calorific restriction leads to longer life span, but the opposite, too many calories are associated with obesity and tumourigenesis. On a cellular level, normal dividing cells activate particular metabolic pathways to accumulate cell mass and energy for DNA synthesis required for reproduction. By contrast tumour cells reprogramme their metabolism, possibly in controlled way, for uncontrolled division and growth. Some genes encoding metabolic enzymes are inactivated while others exhibit increased expression, causing metabolic changes in tumour cells. Recent studies showed that certain glycolytic enzymes mainly active in cytoplasm may move from cytoplasm to the nucleus where they can play different, nonglycolytic functions e.g., control the gene expression. Therefore, to understand the influence of metabolism on gene expression can be crucial to discovering the causes of carcinogenesis.

Oddajemy do rąk Czytelnika kolejny tom z serii „Podstawowe idee i koncepcje w geografii” pt. Dorobek polskiej geografii po konferencji w Rydzynie. Ocena krytyczna. [...] Właśnie minęło 30 lat od przełomowej dla polskiej geografii konferencji w Rydzynie (1983 r.). Miała ona duże znaczenie dla przemian teorii i praktyki geografii. W Rydzynie zwrócono uwagę na odmienne od dotychczasowych możliwości interpretacyjne rzeczywistości badawczej geografii rozwijane zwłaszcza w krajach anglosaskich. W kontekście tym przedstawiono nowe pola badawcze naszej dyscypliny zwłaszcza nieistniejącą wcześniej geografię społeczną jej podejścia radykalne i behawioralne oraz zaprezentowano perspektywę humanistyczną w badaniach geograficznych. Mimo trudności instytucjonalnych w przebijaniu się efektów tej innowacyjnej konferencji do teorii i empirii polskiej geografii, czas pokazał, że jej dorobek nie został zaprzepaszczony. Niniejszy tom składa się z 13 prac, w których autorzy podjęli teoretyczną refleksję nad rolą konferencji w Rydzynie dla polskiej geografii oraz krytyczny namysł nad dorobkiem geografii po konferencji
Automatic Segmentation Framework for Fluorescence in Situ Hybridization Cancer Diagnosis
Part 3: Images, Visualization, ClassificationInternational audienceIn this paper we address a problem of HER2 and CEN-17 reactions detection in fluorescence in situ hybridization images. These images are very often used in situation where typical biopsy examination is not able to provide enough information to decide on the type of treatment the patient should undergo. Here the main focus is placed on the automatization of the procedure. Using an unsupervised neural network and principal component analysis, we present a segmentation framework that is able to keep the high segmentation accuracy. For comparison purposes we test the neural network approach against an automatic threshold method
