New NWA XXX ureilite found in 2006 was investigated by optical microscopy in reflection and in transmission. Olivines, pigeonite, metal veins and dots, and carbon phases have been revealed and their features and distribution studied. Twinning of pigeonite, reduction rims, and poikilitic inclusions of olivine in large pigeonite crystals have been identified and characterized. NWA XXX meteorite belongs to olivine-pigeonite ureilites.

NWA 4967 carbonaceous chondrite thin section was investigated by optical microscopes in transmission and in reflection. Minerals of the meteorite have been identified and microstructure analyzed. Chondrules, matrix, metal phases, AOAs and CAIs are constituents of the rock, as expected. Olivine, clinopyroxene, orthopyroxene, troilite, kamacite and feldspar have been detected. Various types of chondrules including: PO, POP, PP, RP, BO, C, GOP and GO chondrules were identified. Compositional zoning of some olivines, diagnostic cracks in pyroxenes, clinopyroxene twins, and chondrule rims have been observed and analyzed. Our previous EPMA and Raman data as well as present optical data confirm that NWA 4967 belongs to CO3.2 chondrites, as previously classified.

Cd(II) plus iodide species were extracted into PEG-rich phases in the aqueous PEG(1550)-(NH4)2SO4 system at pH 2.05–7.12. IR spectra show that increasing (NH4)2SO4 solution acidity does not protonate PEG ether oxygen atoms, but decreases water content in the PEG-rich phases. Metallic species’ extraction into the PEG predominantly alters how water molecules bind to polymer chains; the changes in their absorption bands depend on pH. Microscopy shows that “fixation” of the extracted metal in the PEG-rich phase occurs by specific interactions which depend on the species. These also determine changes in the polymer chains’ conformation.

Cytoszkielet to sieć białkowych polimerów oraz związanych z nimi setek białek motorycznych, regulatorowych i łączących cytoszkielet z innymi strukturami komórkowymi. Rozwój wiedzy o cytoszkielecie jest nierozerwalnie zwiększany z postępem technik mikroskopowych używanych do jego obserwacji. Początki tych badań to niespecyficzne, nieskomplikowane barwienia utrwalonego materiału biologicznego, które później rozwinęły się w nowoczesną mikroskopię strukturalną, pozwalającą na precyzyjne znakowanie określonych białek tworzących cytoszkielet, badanie ich stanu fizjologicznego czy też oddziaływań cytoszkieletu z luźno związanymi białkami błony czy cytoplazmy. Obecnie możliwe jest nie tylko obrazowanie struktury i funkcji cytoszkieletu ze znacznie lepszą rozdzielczością przestrzenną, ale także prowadzenie tych obserwacji na żywym materiale biologicznym. Z drugiej strony, stabilność cytoszkieletu umożliwia poszukiwanie nowych metod jego obrazowania, co niewątpliwie należy do kół napędowych postępu, jaki dokonał się i wciąż dokonuje się w dziedzinie mikroskopii.

Cytoskeleton is basically a network of protein polymers, but it also contains thousands of motor, regulatory and scaffolding proteins that interact with this network. Discoveries related to the cytoskeleton were strictly connected to the development of microscopy techniques used to observe the cytoskeletal structures. At first, the imaging involved only unspecific, very simple staining of fixed material. Then, the methods evolved into advanced structural microscopy, which enabled accurate detection of specific cytoskeletal proteins, their physiological status, and interactions with loosely bound membrane and cytoplasmic proteins. Today, it is possible not only to visualize the structure and function of the cytoskeleton with better spatial resolution but also to perform the imaging in vivo on live biological specimens. On the other hand, one should also notice that observations of the stable, well defined cytoskeletal structures from their very discovery have continuously stimulated the progress in the microscopy field.
