The chemistry achieved by transformers and generators is (ideally) independent of the substrate introduced, meaning that they must be robust to small adjustments necessary for the adaptation to different starting materials and reagents while ensuring the same chemical outcome. These redefined modules can be used for single-step reactions or in multistep processes, where modules can be connected to each other in reconfigurable combinations to create chemical assembly systems (CAS) targeting compounds and libraries sharing structural cores. With this tutorial review, we provide a guide to the overall approach to flow chemistry, discussing the key parameters for the design of transformers and generators as well as the development of chemical assembly systems.Herein we present DNA probes composed of Hoechst 33258 and spontaneously blinking far-red hydroxymethyl silicon-rhodamine (HMSiR). The best performing probe, 5-HMSiR-Hoechst, contains the 5'-regioisomer, shows ∼400-fold fluorescence increase upon DNA binding and is compatible with wash-free single molecule localization and 3D stimulated emission depletion microscopy of chromatin nanostructures in living cells.Allosteric effects are common in biology, but have not been fully explored in the control of supramolecular polymerization. Herein, ditopic UPy derivatives with acyclic crown ether-like spacers were designed and synthesized, which can undergo supramolecular polymerization through quadruple hydrogen bonding. Upon the addition of K+, drastic molecular conformational change to the U-shape is induced by metal-coordination, reconfiguring remote UPy sites towards the formation of discrete cyclic dimers. Interestingly, the supramolecular polymerization can be restored by simply removing K+ by water-extraction.
The health crisis caused by COVID-19 required the prompt launch of research in order to generate scientific evidence pertaining to the new disease oriented to control its devastating effects and continuous spread. Therefore, it was essential to adapt the work flow of Research Ethics Committees, to prioritize and to accelerate the evaluation of projects related to this disease.

This work analyses the evaluation conducted by our Regional Ethics Committees during the initial period of the health emergency (between 13th March and 28th May 2020).

81 research projects were evaluated, 73 of them of regional scope (62 single-centre), 4 national and 4 international. 57 projects obtained a favourable opinion, 4 were withdrawn by the sponsors, 6 did not require ethics approval and 14 did not respond to the clarifications requested up to the date of the study's closure.

The most important research procedures to be analysed in this context are those related to the methodology and informed consent process. It is also essential to address aspects related to the privacy of personal data, and to take into account the workload of the researchers. As an improvement proposal, we think that greater collaboration between the different research teams should be encourage to obtain more robust results.

Colloidal nanoparticles are of significant interest in biomedical applications due to a large number of solution-based bioconjugation procedures. Nevertheless, the inherent polydispersity of the nanoparticles produced by various techniques necessitates the employment of high yield separation and purification techniques. Here we demonstrate the employment of gel filtration on non-stoichiometric plasmonic MoO x nanoparticles, prepared by an oxidation process during liquid-phase exfoliation of few-layer MoS2 nanosheets. This resulted in the separation of two types of MoO x particles, in the form of two different chromatographic fractions. They showed different sizes, morphological and optical properties. The fraction containing smaller particles with diameters of 1-4 nm, exhibited an increased absorbance peak in the near IR region and responded with a significant temperature increase to laser irradiation at the wavelength close to the maximal absorption. The fraction with the larger particles from 3 up to 10 nm, showed weak photoluminescence and a preferred orientation upon the deposition on a planar substrate. However, it had no absorbance in the near IR compared to the former fraction. According to our knowledge, this is the first time that the gel filtration was applied to the separation of molybdenum oxide nanomaterials. This step ensured the isolation of plasmonic MoO x nanoparticles suitable for further bioconjugation and target photothermal treatment.A selective prolyl endopeptidase (PEP) inhibitor benzyloxycarbonyl-prolyl-prolinal (IC50 = 1,61±0,12 nmol/l) and a nonselective PEP inhibitor benzyloxycarbonyl-methionyl-cyanopyrrolidine (IC50 = 2,01±0,14 nmol/l) exhibit a comparable antiexudative effect at single doses of 2 mg/kg and 5 mg/kg (intraperitoneally) in outbred mice with peritonitis induced by 1% acetic acid. However, only benzyloxycarbonyl-methionyl-cyanopyrrolidine at a dose of 5 mg/kg reduces acetic acid induced pain in animals.We studied the effects of acute, subacute, and chronic alcohol treatment of rats on the content of fibroblast growth factor 2 (FGF2) mRNA in various brain structures. Results suggest a possible role of FGF2 in the functioning of dopaminergic neurons in the midbrain. Plumbagin In our experiment, ethanol treatment of rats was accompanied by an increase in the FGF2 mRNA level in the emotiogenic structures of the brain. This effect was blocked by pretreatment of animals with chlorpromazine. This suggests FGF2 involvement in the mechanisms of alcohol dependence and can be considered as a possible diagnostic and therapeutic target in alcoholism.
