KONSTRUKCJA AUKSOTROFICZNEGO WZGLĘDEM L-LIZYNY SZCZEPU CANDIDA ALBICANS
PublicationEnzymy szlaku kwasu L-α-aminoadypinowego biosyntezy L-lizyny z Candida albicans są potencjalnymi celami molekularnymi w terapii przeciwgrzybowej. Niektóre grupy badawcze wykazały, że auksotrofia wobec L-lizyny u pewnych gatunków grzybów powoduje zmniejszenie ich zjadliwości i może mieć wpływ na wzrost in vivo [Liebmann i in. 2004]. Oznacza to, że można się spodziewać zahamowania wzrostu komórek grzybowych w wyniku działania selektywnych...

Thermal and mechanical properties of polyurethanes modified with L-ascorbic acid
PublicationIn this study we report the thermal and mechanical properties of polyurethanes modified with ascorbic acid (AA). Ascorbic acid was used as a modifier at concentration of 1 or 2 mass%. The antioxidative properties of AA may improve the biocompatibility of the obtained materials, which were designed for biomedical applications. In this paper we describe characterization of obtained unmodified and ascorbic acid modified polyurethanes...

Effect of pH on optical sensing with poly-L-lysine-modified nanodiamonds
PublicationNitrogen-vacancy (NV) centers are crystallographic defects which provide diamonds with unique physical properties. The centers are known for their intensive, time-stable fluorescence, and an electron spin, which exhibits long coherence time and may be manipulated using external stimuli. Nanodiamonds containing the NV centers are promising tools in biolabeling, biosensing, and drug delivery due to the aforementioned properties of...

N-Alkyl Derivatives of L-Glutamine As Inhibitors of Glutamine - Utilizing Enzymes
PublicationA general facile method to synthesize the N-gamma-alkyl and N-gamma,N-gamma-dialkyl derivatives of L-glutamine (1a-d) from L-glutamic acid as a starting substrate is presented. The obtained compounds are shown to inhibit three diferent glutamine-utilizing enzymes, namely: glutaminase, gamma-glutamyl transpeptidase, and glucosamine-6-phosphate synthase, with inhibitory constants within the milimolar range.

Reduction in Errors in Roughness Evaluation with an Accurate Definition of the S-L Surface
PublicationCharacterization of surface topography, roughly divided into measurement and data analysis, can be valuable in the process of validation of the tribological performance of machined parts. Surface topography, especially the roughness, can respond straightly to the machining process and, in some cases, is defined as a fingerprint of the manufacturing. When considering the high precision of surface topography studies, the definition...

In-tube extraction for the determination of the main volatile compounds in Physalis peruviana L
PublicationAn analytical procedure based on in-tube extraction followed by gas chromatography with mass spectrometry has been developed for the analysis of 24 main volatile components in cape gooseberry (Physalis peruviana L.) samples. According to their chemical structure, the compounds were organized into different groups: one hydrocarbon, one aldehyde, four alcohols, four esters, and 14 monoterpenes. By single-factor experiments, incubation...

Antifungal activity of L-homoserine O-acetyltransferase (CaMet2p) inhibitors.
Open Research DataThe dataset contains a set of optical densities at 600 nm measured at microplate reader to determine the rate of fungal growth in the presence of Candida albicans homoserine O-acetyltransferase inhibitors. Antifungal activities were determined against several strains from Candida spp. and others by the modified M27-A3 method specified by the CLSI. We...
