Amino-Acid-Anthraquinone Click Chemistry Conjugates Selectively Target Human Telomeric G-Quadruplexes

Guanine-rich sequences are known to fold into G-quadruplex (G4) arrangements, which are present in oncogenes and in the telomeric regions of chromosomes. In particular, G4s represent an obstacle to functioning of telomerase, an enzyme overexpressed in cancer cells causing their immortalization. Therefore, G4 stabilization using small molecules represents an appealing strategy for the medicinal chemist. Ligands based on an anthraquinone scaffold, to which peptidic side chains were attached by an amide bond, were previously reported. We envisioned improving this ligand concept leveraging the click chemistry approach, which, besides representing a flexible, high yielding synthetic strategy, allows an elongation of the side chains and an increase of π–π stacking and H-bond interactions with the nucleobases through the triazole ring. Compounds were tested for their ability to interact with G4 DNA with a multiple analytical approach, demonstrating an elevated aptitude to stabilize the G4 and high selectivity over double stranded DNA.

Analysis of cell aggregation in the culturing of cerebellar granule neurons

We have proposed previously that an increased concentration of growth factor secreted by neurons themselves has a direct effect on survival of the neurons, and thereby cell density serves as a regulator of survival of neurons. In this study, the same idea was used to analyze the aggregation of cerebellar granule neurons in culture experimentally and theoretically. Assuming the transport of growth factor and substrate within an aggregate is by molecular diffusion, the metabolic efficiency of neurons, on the basis of an autocatalytic phenomenon, was increased within an aggregate compared to an identical quantity of dispersed cells. A good agreement in the size of neuronal aggregate between the theoretical prediction and the experimental result was found. This illustrates that growth factors produced by neurons acting in either an autocrine or paracrine manner play an important role during the development of cultured neurons.     

Rapid thermal annealing effect of transparent ITO source and drain electrode for transparent thin film transistors

We investigated the rapid thermal annealing (RTA) sequence effect on the electrical, optical, morphological, and structural properties of transparent thin film transistors (TTFTs) with an indium gallium zinc oxide (IGZO) channel and an indium tin oxide (ITO) source/drain. The electrical and optical properties of the IGZO channel and the ITO source/drain electrodes were compared as a function of RTA temperature in ambient air. The performance of a TTFT with only an RTA-processed IGZO channel was compared with that of a TTFT with an RTA-processed IGZO channel and ITO source/drain electrodes. Using the circular transmission line measurement (CTLM) method, we suggest a possible mechanism that explains the effect of the RTA process on the performance of the TTFT with only an annealed IGZO channel vs. that with an annealed IGZO/ITO multilayer. The TTFT with an RTA-processed IGZO/ITO multilayer showed a threshold voltage shift, an improved on/off ratio of 3.54 × 10¹¹, a subthreshold swing of 0.33 V/decade, and a high mobility of 8.69 cm²/V·s. This indicates that simultaneous RTA processing for an IGZO channel and an ITO electrode is beneficial for the fabrication of high-performance TTFTs.     

Stress Analysis of T-type Butt Adhesive Joint Subjected to External Bending Moments

Stress distributions and displacements at the interface between an adhesive and an adherend are examined when a T-type butt adhesive joint, in which two thin plates are joined, is subjected to an external bending moment. In the analyses, general representations of the stresses and the displacements are given using a two-dimensional theory of elasticity in the case where two dissimilar plates are joined. Next, in the case of plates with the same material, effects of Young's modulus of plates to that of an adhesive and the thickness of the adhesive on the stress distribution are made clear by numerical computations. For verification, experiments are performed and an analytical result is in a fairly good agreement with an experimental one.     

Study of aluminium bonded joints by analytical electron microscopy: Microstructural changes with aging

This study concerns the influence of aging on the microstructural characteristics of each component in bonded joint systems consisting of an aluminium alloy substrate (2024) clad with an aluminium sheet, an oxide layer obtained by surface treatment ('optimized' chromic-sulphuric acid etching, chromic acid anodizing, or phosphoric acid anodizing), an epoxy-novolac-based composite primer, and an epoxy-based adhesive film. The samples studied were obtained by ultrathin cross-section microtomy of the bonded joints (before and after aging). The microcharacterization was carried out using a transmission electron microscope (TEM) equipped with an X-ray energy-dispersive spectrometer (EDS), an electron energy-loss spectrometer (EELS), and an energy-filtered imaging system. Detailed analyses revealed that microstructural changes occur during aging in the primer in contact with the oxidized substrate and that the thickness of the modified zone depends on the underlying oxide. In addition, it is shown that a 'true' interphase about 200 nm thick is formed between the primer and adhesive by a diffusional process.

Experimental study and mathematical simulation of the crystallization of ammonium sulfate in a forced circulation crystallizer

The growth mechanism of ammonium sulfate crystals is studied. A mathematical model for the process of continuous crystallization in an experimental FC-crystallizer based on the previously reported model of crystal attrition is developed. A mathematical model for the mass crystallization of ammonium sulfate in an industrial crystallizer with forced circulation by an axial three-blade propeller pump, which takes into account the impact of crystals onto its blades, is developed as well. Optimal operating conditions for an industrial crystallizer, the parameters of an axial propeller pump, and its operating conditions for producing crystals of a given size at minimal power consumption are chosen.     

Particle Size Control and Crystal Habit Modification of Phenacetin Using Ultrasonic Crystallization

Power ultrasound is applied for cooling crystallization to control and modify the particle size and crystal habit of an active pharmaceutical ingredient, phenacetin. Operating parameters including sonication intensity and duration, solution concentration, and cooling rate are studied and compared. With respect to mean particle size, the effect of sonication intensity is most significant. In addition, the crystal habit of recrystallized phenacetin is modified substantially and shows an elliptic shape. Recrystallized phenacetin also provides an enhanced dissolution rate compared with the original sample. These results prove that ultrasonic crystallization is an efficient tool for controlling the solid‐state properties of an active pharmaceutical ingredient.     

Bestimmung von Pentan als Indikator für die oxidative Ranzigkeit von Ölen

Determination of Pentane as an Indicator of Oil Rancidity Pentane, determined by a headspace gas chromatographic method, is an excellent indicator of oil rancidity. The methodology applied is very simple and could be performed in an oil laboratory without purchasing additional equipment. The amount of pentane correlated well with the iodometrically determined peroxide value (R²-value of 0.976). Heating the oil sample in air followed by an estimation of pentane is an alternative means to assess oil stability against oxidative deterioration.
