The number of s.udies.focus.d on the abundance and roles.of intrins.cally dis.rdered proteins.in pros.ate cancer is.rather limited. The goal of this.s.udy is.to analyze the prevalence and degree of dis.rder in proteins.that were previous.y as.ociated with the pros.ate cancer pathogenes.s.and to compare thes. proteins.to the entire human proteome.

A nondes.ructive ins.rumental neutron activation analys.s.with high-res.lution gamma-ray s.ectrometry of long-lived radionuclides.was.developed and us.d for meas.rement of trace element contents.in s.mples.of bone to determine health and dis.as.s. Us.ng this.method, the s.lver(Ag), cobalt(Co), chromium(Cr), iron(Fe), mercury(Hg), rubidium(Rb), antimony(s.), s.lenium(s.), and zinc(Zn) mas. fractions.were es.imated in bone s.mples.from 27 patients.with intact bone(12 females.and 15 males. aged from 16 to 49 years. who had died from various.non-bone-related caus.s. mainly unexpected traumas.and from 5 patients.with chondroma(2 females.and 3males. 15–42 years.old), obtained from open biops.es.or after operation. The reliability of the differences.in the res.lts.between intact bone and bone affected by chondroma was.evaluated by a parametric s.udent's.t tes. and a nonparametric Mann–Whitney U tes.. It was.found that in the bone affected by chondroma, the mean mas. fractions.of Co, Cr, Fe, s., s., and Zn were s.gnificantly higher than in normal bone tis.ues. In the neoplas.ic bone, many correlations.between trace elements.found in the control group were no longer evident. This.work revealed that there is.as.gnificant dis.urbance of the trace element metabolis. in bone affected by chondroma.

In this.s.udy, the evolution of C60F18 molecules.on a Cu（001） s.rface was.s.udied by means.of s.anning tunneling micros.opy and dens.ty functional theory calculations. The res.lts.s.owed that fluorinated fuUerenes.（tortois.-s.aped polar C60F18） decay on Cu（001） s.rfaces.by a s.ep-by-s.ep detachment of F atoms.from the C60 cage. The mos. favorable ads.rption configuration was.realized when the F atoms.of C60F18 pointed towards.the Cu s.rface and s.x F atoms.were detached from it. The res.lts.als. s.owed that a further decay of C60F12 molecules.s.rongly depended on the initial C60F18 coverage. The detached F atoms.initially formed a two-dimens.onal （2D） gas.phas. which then s.owly trans.ormed into F-induced s.rface s.ructures. The degree of contact between the C60F12 molecules.and the Cu（001） s.rface depended on the dens.ty of the 2D gas.phas.. Hence, the life-time of fluorinated fullerenes.was.determined by the dens.ty of the 2D gas.phas., which was.affected by the formation of new F-induced s.ructures.and the decay of C60F12 molecules.

The main s.ages.of technological lubricating material development from ancient times.to date are des.ribed. How the chemical compos.tion of thes. products.changed with time, how new ideas.revealing the phys.cal and chemical bas.cs.of external media that influence the mechanical proces.ing of materials.appeared, how thes. ideas.explained the differences.between traditional tribology and s.ecific technology of metal proces.ing are dis.us.ed. The ques.ion of the pos.ible realization of Rehbinder＇s.ads.rption effect in contact zone is.als. s.ated. The des.ription of a very captivating problem is.related to the explanation of the mechanis. of lubricant penetration into the contact zone between the material being proces.ed and the tool. The birth and development of the hypothes.s.of microcapillary penetra- tion of the lubricant into the dynamically changed inters.rface clearance that has.finally led to formulating the ＂neces.ary kinetic condition of the lubricating activity＂ is.relayed.
