Physical review letters

Huber T, Mariager SO, Ferrer A, Schäfer H, Johnson JA, Grübel S, Lübcke A, Huber L, Kubacka T, Dornes C, Laulhe C, Ravy S, Ingold G, Beaud P, Demsar J, Johnson SL.
PMID: 25062214
Phys Rev Lett. 2014 Jul 11;113(2):026401. doi: 10.1103/PhysRevLett.113.026401. Epub 2014 Jul 11.

Using femtosecond time-resolved x-ray diffraction, we directly monitor the coherent lattice dynamics through an ultrafast charge-density-wave-to-metal transition in the prototypical Peierls system K(0.3)MoO(3) over a wide range of relevant excitation fluences. While in the low fluence regime we directly...

Microbiological quality of non-sterile pharmaceutical products.

Saudi pharmaceutical journal : SPJ : the official publication of the Saudi Pharmaceutical Society

Ratajczak M, Kubicka MM, Kamińska D, Sawicka P, Długaszewska J.
PMID: 26106278
Saudi Pharm J. 2015 Jul;23(3):303-7. doi: 10.1016/j.jsps.2014.11.015. Epub 2014 Dec 08.

In microbiological terms, pharmaceutical products can be divided into two groups: sterile and non-sterile. Non-sterile drugs must satisfy the appropriate microbiological purity criteria which are included in pharmacopoeial monographs. Pharmacopoeial studies are prepared specifically with a view to ensuring...

MICROBIOLOGICAL QUALITY OF FOOD SUPPLEMENTS.

Acta poloniae pharmaceutica

Ratajczak M, Kubicka MM, Kamińska D, Długaszewska J.
PMID: 26642690
Acta Pol Pharm. 2015 Mar-Apr;72(2):383-7.

Many specialists note that the food offered today - as a result of very complex technological processing - is devoid of many components that are important for the organism and the shortages have to be supplemented. The simplest for...

Elimination of extrachromosomal c-myc genes by hydroxyurea induces apoptosis.

Apoptosis : an international journal on programmed cell death

Petit T, Davidson K, Izbicka E, Von Hoff DD.
PMID: 14634278
Apoptosis. 1999 Jun;4(3):163-7. doi: 10.1023/a:1009606421419.

Hydroxyurea (HU) increases extrachromosomal DNA elimination in tumor cell lines. The c-myc oncogene is one of the many relevant amplified genes contained within the extrachromosomal DNA compartment. Spontaneous loss of amplified copies of c-myc induces terminal differentiation and apoptosis...

BACKGROUND: Transjugular liver biopsy (TJLB) is frequently used to obtain liver specimens in high-risk patients. However, TJLB sample size possibly limits their clinical relevance.METHODS: 102 patients that underwent TJLB were included. Clinical parameters and outcome of TJLB were analyzed....

Notes on the photo-induced characteristics of transition metal-doped and undoped titanium dioxide thin films.

Journal of colloid and interface science

Kment S, Kmentova H, Kluson P, Krysa J, Hubicka Z, Cirkva V, Gregora I, Solcova O, Jastrabik L.

This study reports the preparation of thin nanoparticulate films of titanium dioxide and its modified version doped with a transition metal. The behavior of prepared films was described by means of their photocatalytic and photo-induced electrochemical properties. The TiO(2)...

Changes of physical and chemical properties and of histological structure of meat subjected to massage under vacuum.

PMID: 22054974
Meat Sci. 1978 Apr;2(2):145-53. doi: 10.1016/0309-1740(78)90014-1.

Differences were found in a number of attributes (pH value, changes in volume and linear dimensions, cooking loss, tenderness and water-holding capacity) between porcine muscles subjected to vacuum massage and those in non-massaged controls. Histologically there were changes in...

Anion exchange in [Ni(η(5)-C(5)H(4)R)(Cl)(NHC)]. Counterion effect on the structure and catalytic activity.

A series of novel complexes [Ni(η(5)-C5H4R)(L)(NHC)](+)A(-)2a-2j and [Ni(η(5)-C5H5)(A)(NHC)] 3a-3c has been obtained by anion metathesis from the corresponding chlorides 1a-1d, depending on the anion binding properties and reaction conditions. Solid-state structures of two cationic complexes (2c, 2j) and two...
