Selectively substituted derivatives of α-cyclodextrin and hexa-O-tert-butyldimethylsilyl-α-cyclodextrin containing a definite number of acylated primary or secondary hydroxy groups were synthesized using benzoic, acetylsalicylic, and 2-(4-isobutylphenyl)propionic acid chlorides in various solvents in the presence of different bases. The acyl residues were assigned to the C2, C3, or C6 atoms in the carbohydrate fragments on the basis of 13C NMR data. Desilylation of the silyl derivatives with ammonium fluoride in methanol gave the corresponding O-acyl derivatives having free primary hydroxy groups in the α-cyclodextrin skeleton. © 2011 Pleiades Publishing, Ltd.

In a recent study, we demonstrated that transient receptor potential melastatin 8 (TRPM8), a calcium-permeable cation channel that is activated by cold temperatures, is localized in the bronchial epithelium and is upregulated in subjects with chronic obstructive pulmonary disease, which causes them to be more sensitive to cold air. In the present study, we found that exposure to cold temperatures induced ciliary ultrastructural anomalies and mucus accumulation on the epithelial surface. Male Sprague-Dawley rats were exposed to cold temperatures to determine the effects of cold air on ultrastructural changes in cilia and the airway epithelial surface. The rats were also exposed to cigarette smoke and/or cold temperatures to determine the effects of smoke and cold air on TRPM8 expression and the role of cold air in cigarette smoke-induced mucus hypersecretion. Following real-time RT-PCR and western blot analysis, we observed a high expression of TRPM8 mRNA and protein in the bronchial tissue following cigarette smoke inhalation. As shown by ELISA, concurrent cold air enhanced the levels of mucin 5AC (MUC5AC) protein, as well as those of inflammatory factors [tumor necrosis factor (TNF)-α and interleukin (IL)-8] that were induced by cigarette smoke inhalation to a greater extent than stimulation with separate stimuli (cold air and cigarette smoke separately). The results suggest that cold air stimuli are responsible for the ultrastructural abnormalities of bronchial cilia, which contribute to abnormal mucus clearance. In addition, cold air synergistically amplifies cigarette smoke-induced mucus hypersecretion and the production of inflammatory factors through the elevated expression of the TRPM8 channel that is initiated by cigarette smoke inhalation.

The components of cognitive operant behavior of rats was investigated after preliminary development of a unilateral conditioned reinforcement reflex ofan active avoidance aversive stimulus in the problem chamber. It is established, that cognitive abilities associated with phenotypes factors, as age and a sex. In applied aspect of research comparable actions by efficiency with Pyracetamum are reveal nootrop and activating properties at the Chinese vegetative preparation. Use of neurotropic preparations has allowed reveal their positive and negative influence on primary mental components operant behavior of an active avoidance. © 2014, Maik Nauka-Interperiodica Publishing.
