Inflammatory Proteins HMGA2 and PRTN3 as Drivers of Vulvar Squamous Cell Carcinoma Progression.

Current knowledge on the biology of squamous cell vulvar carcinoma (VSCC) is limited. We aimed to identify protein markers of VSCC tumors that would permit to stratify patients by progression risk. Early-stage tumors from patients who progressed (progVSCC) and from those who were disease-free (d-fVSCC) during follow-up, along with normal vulvar tissues were examined by mass spectrometry-based proteomics. Differentially expressed proteins (DEPs) were then verified in solid tissues and blood samples of patients with VSCC tumors and vulvar premalignant lesions. In progVSCC vs. d-fVSCC tumors, the immune response was the most over-represented Gene Ontology category for the identified DEPs. Pathway profiling suggested bacterial infections to be linked to aggressive VSCC phenotypes. High Mobility Group AT-Hook 2 (HMGA2) and Proteinase 3 (PRTN3) were revealed as proteins predicting VSCC progression. HMGA2 and PRTN3 abundances are associated with an aggressive phenotype, and hold promise as markers for VSCC patient stratification. It appears that vulvovaginal microflora disturbances trigger an inflammatory response contributing to cancer progression, suggesting that bacterial rather than viral infection status should be considered in the development of targeted therapies in VSCC

Lichen diversity in the managed forests of the Karnieszewice Forest Division and its surroundings (N Poland)

The lichen biota of the Karnieszewice Forest Division (N Poland) is presented. Despite it is predominantly a strongly managed woodland area, 270 lichen species were found there including many rare species for Poland, as well as for European Lowland. Near 20% of the whole lichen biota are considered to be threatened in the country (categories CR, EN, VU), and 34 species are protected by law in Poland. Agonimia flabelliformis is reported for the second time from Polish lowlands

Spatial Nano-Morphology of the Prolamellar Body in Etiolated Arabidopsis thaliana Plants With Disturbed Pigment and Polyprenol Composition

The prolamellar body (PLB) is a periodic bicontinuous membrane structure based on tubular tetrahedral units. PLBs are present in plant etioplasts and, upon illumination, directly transform into the lamellar thylakoid networks within chloroplasts. Efficient tubular-lamellar rearrangement and later formation of the photosynthetically active thylakoid membranes are crucial steps in the development of plant autotrophy. PLB membranes are mainly composed of galactolipids, carotenoids, and protochlorophyllide (Pchlide), the chlorophyll precursor, bound in a complex with NADPH and Pchlide oxidoreductase. Although the PLB structure has been studied for over 50 years, the direct role of particular membrane components in the formation of the PLB paracrystalline network remains elusive. Moreover, despite the numerous literature data regarding the PLB geometry, their reliable comparative analysis is complicated due to variable experimental conditions. Therefore, we performed comprehensive ultrastructural and low-temperature fluorescence analysis of wild type Arabidopsis thaliana (Arabidopsis) seedlings grown in different conditions typical for studies on etiolated seedlings. We established that the addition of sucrose to the growing media significantly affected the size and compactness of the PLB. The etiolation period was also an important factor influencing the PLB structural parameters and the ratio of free to complex-bound Pchlide. Thus, a reliable PLB structural and spectral analysis requires particular attention to the applied experimental conditions. We investigated the influence of the pigment and polyprenol components of the etioplast membranes on the formation of the PLB spatial structure. The PLB 3D structure in several Arabidopsis mutants (ccr1-1, lut5-1, szl1-1npq1-2, aba1-6, pif1, cpt7) with disturbed levels of particular pigments and polyprenols using electron tomography technique was studied. We found that the PLB nano-morphology was mainly affected in the pif1 and aba1-6 mutants. An increased level of Pchlide (pif1) resulted in the substantial shift of the structural balance between outer and inner PLB water channels and overall PLB compactness compared to wild type plants. The decrease in the relative content of β-branch xanthophylls in aba1-6 plants was manifested by local disturbances in the paracrystalline structure of the PLB network. Therefore, proper levels of particular etioplast pigments are essential for the formation of stable and regular PLB structure

The lichen biota of three nature reserves in island Saaremaa, Estonia

A description of the lichen biota of three nature reserves – Kaugatoma-Lõo, Odalätsi and Viieristi reserves in Saaremaa island, Estonia is presented. In total 404 species are listed, of them 228 are recorded from Kaugatoma-Lõo, 169 from Odalätsi and 167 from Viieristi reserves. The composition of the lichen biota of the reserves reflects the availability of habitats (alvar grasslands, sand dunes, different types of forests) in the area. The share of rare and protected species is the highest in Kaugatoma-Lõo reserve because of the rare in Estonia habitats (thin calcium-rich soils) and substrata (lignum of old, dead junipers). Ramalina elegans, previously considered as extinct in Estonia, was re-found from Odalätsi and Viieristi reserves.

Pielęgniarstwo na rzecz milenijnych celów rozwoju. Cz. 2

Praca recenzowana / Peer-reviewed paperZ przyjemnością oddajemy w Państwa ręce drugi tom monografii wydanej z okazji XII Kongresu Pielęgniarek Polskich w Krakowie, w którym udział wzięło blisko 500 pielęgniarek, zaprezentowano 160 prac w 9 sesjach. Ta kolejna już publikacja świadczy o dynamicznym rozwoju badań naukowych w pielęgniarstwie. Dowodzi, że pielęgniarstwo to nie tylko zawód, ale i interdyscyplinarna nauka
