A study of cell membranes in nasal epithelial cells from patients with chronic rhinosinusitis with nasal polyps by means of a fluorescent probe

Aim. To assess the state of membranes in nasal epithelial cells obtained from the patients with chronic rhinosinusitis with nasal polyps (CRSwNP) with the help of the fluorescent probe 2-(2ʹ-ОН-phenyl)-5-phenyl-1,3-oxazole. Methods. The state of membrane phospholipid bilayer in suspensions of nasal epithelial cells isolated from ten patients with CRSwNP was evaluated using the fluorescent probe 2-(2ʹ-ОН-phenyl)-5-phenyl-1,3-oxazole that reacts on the physico-chemical properties of its microenvironment. Changes in fluorescence spectra were determined using a Thermo Scientific Lumina fluorescence spectrometer (Thermo Fisher Scientific) 1 hour after the addition of the probe to nasal epithelial cell suspensions. Results. CRSwNP was found to be associated with a higher rate of nasal epithelial cell membrane hydration in the region of phospholipid glycerol moiety, carbonyl groups and aliphatic chains of fatty acids attached to the carbonyl groups. Conclusion. Our findings suggest that CRSwNP is accompanied by the elevated hydration rate of the most polar region, namely polar heads of phospholipids of nasal epithelial cell membranes

Coulomb Charging Effects in an Open Quantum Dot

Low-temperature transport properties of a lateral quantum dot formed by overlaying finger gates in a clean one-dimensional channel are investigated. Continuous and periodic oscillations superimposed upon ballistic conductance steps are observed, when the conductance G of the dot changes within a wide range 0<G<6e^2/h. Calculations of the electrostatics confirm that the measured periodic conductance oscillations correspond to successive change of the total charge of the dot by $e$. By modelling the transport it is shown that the progression of the Coulomb oscillations into the region G>2e^2/h may be due to suppression of inter-1D-subband scattering. Fully transmitted subbands contribute to coherent background of conductance, while sequential tunneling via weakly transmitted subbands leads to Coulomb charging of the dot.Comment: 12 pages, RevTeX, 15 eps figures included, submitted to Phys.

Collective Oscillations of Vortex Lattices in Rotating Bose-Einstein Condensates

The complete low-energy collective-excitation spectrum of vortex lattices is discussed for rotating Bose-Einstein condensates (BEC) by solving the Bogoliubov-de Gennes (BdG) equation, yielding, e.g., the Tkachenko mode recently observed at JILA. The totally symmetric subset of these modes includes the transverse shear, common longitudinal, and differential longitudinal modes. We also solve the time-dependent Gross-Pitaevskii (TDGP) equation to simulate the actual JILA experiment, obtaining the Tkachenko mode and identifying a pair of breathing modes. Combining both the BdG and TDGP approaches allows one to unambiguously identify every observed mode.Comment: 5 pages, 4 figure

Poremećaji reprodukcijske funkcije u mužjaka štakora uzrokovani unosom tekućine bogate fruktozom od 23 dana starosti do puberteta

There is compelling evidence that a hypercaloric, high-fructose diet can cause metabolic syndrome (MetS) and a whole range of other metabolic changes. In the context of androgen deficiency, MetS in boys merits special attention, but the effects of fructose-rich diet in youth on future male reproductive function are still poorly evidenced. The aim of this study was to address this issue and analyse the effects of high-fructose intake starting from weaning to puberty (postnatal day 23 up to 83) on the reproductive function of male rats. For this purpose juvenile male Wistar rats were divided in two groups: control and the group receiving 10 % fructose solution instead of drinking water. Reproductive function was evaluated in terms of fertility, sperm count, testes/epididymis morphology, and serum sex hormones. The fructose-treated group showed a decrease in testosterone and twofold increase in luteinising and follicle-stimulating hormone levels in the serum. This was accompanied with lower testis/epididymis weights, sperm count, and changed testis/epididymis morphology. Their fertility remained unchanged, but the fertility of females mating with these males diminished. In addition, pre-implantation and post-implantation embryonic death rate rose in these females. Our results have confirmed that high fructose consumption from early age until puberty can impair the reproductive function of male rats, and call for further animal and epidemiological investigation.Postoje snažni dokazi da hiperkalorična prehrana bogata fruktozom može uzrokovati metabolički sindrom (MetS) i cijeli niz drugih promjena u metabolizmu. U smislu androgene deficijencije, MetS u dječaka izaziva posebnu pažnju, ali nema mnogo spoznaja o učincima prehrane bogate fruktozom u ranoj mladosti na buduću reprodukcijsku funkciju u muškaraca. Stoga je cilj ovoga istraživanja bio analizirati učinke unosa tekućine bogate fruktozom u mladih mužjaka štakora od trenutka kad su prestali sisati (23 dana starosti) do puberteta (83 dana starosti) na njihovu reprodukcijsku funkciju. U tu su svrhu muški Wistar štakori podijeljeni u dvije skupine: kontrolnu i onu koja je primala 10 %-tnu otopinu fruktoze umjesto vode za piće. Parametri procjene reprodukcijske funkcije obuhvatili su plodnost, broj spermija, morfologiju testisa (sjemenika) i epididimisa (pasjemenika) te razine spolnih hormona u serumu. U skupini koja je primala fruktozu zamijećeno je smanjenje razine testosterona i dvostruko povećanje razina luteinizirajućega i folikulostimulirajućega hormona u serumu u odnosu na kontrolnu skupinu. Te su promjene popraćene padom težine testisa i epididimisa, broja spermija te promjenama u morfologiji testisa i epididimisa. Plodnost im se nije promijenila, ali je zato plodnost ženki koje su se parile s mužjacima izloženima fruktozi bila smanjena. Osim toga, u tih se ženki povećala smrtnost embrija prije i nakon implantacije u odnosu na ženke koje su se parile s kontrolnim mužjacima. Naši rezultati potvrđuju pretpostavku da konzumacija hrane i pića bogatih fruktozom od rane dobi do puberteta može oštetiti reprodukcijsku funkciju u štakora. Stoga je potrebno provesti daljnja istraživanja u životinja te epidemiološka istraživanja u ljudi

The choice of the medium sanation in the treatment of acute widespread purulent peritonitis by the method of laparostomy in combination with programmed of the abdominal cavity sanitation

The accumulated clinical experience and analysis of our own results of treatment of patients with severe forms of acute widespread purulent peritonitis, speaks about the growing urgency of this problem. The aim of this study was determination of the most optimal medium sanation during execution programs of the abdominal cavity sanitation in acute diffuse purulent peritonitis.Was studied the treatment results of 79 patients with severe forms of acute widespread purulent peritonitis. After laparotomy and performing a biopsy was conducted qualitative and quantitative morphological study of the inflammatory process in the peritoneum on the background of the landmark of the abdominal cavity sanitation of  two groups of patients with acute widespread purulent peritonitis before and after carrying out the programmatic sanitation of the abdominal cavity, using a solution of octenidine dihydrochloride and saline solution.In the result of study, authors came to the conclusion, that the application, as it seemed different sanation mediums do not affect on the basic morphometric parameters of the studied biopsies of the peritoneum after sanitation of abdominal cavity.This confirms the theory of "mechanical purification" of the abdominal cavity, and sanitation of the abdominal cavity does not depend on the qualitative composition of the sanation medium

Zero-energy states in rotating trapped Bose-Einstein condensates

We have calculated low-lying quasiparticle excitation spectra of rotating three-dimensional Bose-Einstein condensates. As opposed to the prediction of hydrodynamic continuum theories, we find a minimum in the Tkachenko mode spectrum at intermediate rotation frequencies of the harmonic trap. Such a minimum can harbour a Tkachenko quasiparticle with zero excitation energy. We discuss the experimental signatures of such a zero mode.Comment: 14 pages, 6 figure
