Water Adsorption Dynamics on Metal-Organic Framework MOF-801: Comparative Study of Loose and Glued Grains, and Coatings.

Adsorption heat transformation and storage (AHTS) is an environmentally benign and energy-saving alternative to common compression chillers and heat pumps. The low specific power (SP) of adsorption systems is a key drawback that hinders their broader dissemination. The optimization of adsorption dynamics is a prerequisite for SP enhancement.

The impact of framework flexibility and defects on the water adsorption in CAU-10-H.

Aluminum-based metal-organic framework (MOF) CAU-10-H is a promising candidate for heat transformation and water harvesting applications due to its hydrothermal stability, beneficial step-wise water adsorption isotherm and low toxicity. In this study, the effects of the framework flexibility and structural defects on the mechanism of water sorption in CAU-10-H were studied by grand canonical Monte Carlo (GCMC) methods. It was shown by the simulations that the rigid ideal MOF framework is hydrophobic.

Immuno-hormonal network in postmenopausal women: disturbance in breast cancer patients.

Introduction: Antibodies to estradiol and progesterone (Es and Pg) modulated their blood serum concentration and biological effects in immunized animals. Antibodies to membrane steroid receptors acted as hormone agonists or antagonists in cell cultures.

Material And Methods: Here we studied the levels of Es and Pg, idiotypic immunoglobulin (Ig) A1 and anti-idiotypic IgG2 specific to Es and Pg in the serum of postmenopausal women (82 healthy donors and 443 breast cancer patients).

Water Vapor Adsorption on CAU-10-: Effect of Functional Groups on Adsorption Equilibrium and Mechanisms.

Metal-organic frameworks (MOFs) possess unique flexibility of structure and properties, which drives them toward applications as water adsorbents in many emerging technologies, such as adsorptive heat transformation, water harvesting from the air, dehumidification, and desalination. A deep understanding of the surface phenomena is a prerequisite for the target-oriented design of MOFs with the required adsorption properties. In this work, we comprehensively study the effect of functional groups on water adsorption on a series CAU-10- substituted with both hydrophilic ( = NH) and hydrophobic ( = NO) groups in the linker.

A close view of the organic linker in a MOF: structural insights from a combined H NMR relaxometry and computational investigation.

The organic linker in a metal organic framework (MOF) affects its adsorption behavior and performance, and its structure and dynamics play a role in the modulation of the adsorption properties. In this work, the combination of H nuclear magnetic resonance (NMR) longitudinal relaxometry and theoretical calculations allowed details of the structure and dynamics of the organic linker in the NH-MIL-125 MOF to be obtained. In particular, fast field cycling (FFC) NMR, applied here for the first time on MOFs, was used to disclose the dynamics of the amino group and its electronic environment through the analysis of the N quadrupole relaxation peaks, observed in the frequency interval 0.

Inversion of natural immuno-hormonal interactions under influence of antibodies against environmental chemical carcinogens.

In this article we present a hypothesis that interactions between sex hormones and specific antibodies change inversely in presence of antibodies against environmental carcinogens. Natural occurrence antibodies to estradiol (E2) and progesterone (Pg) do not influence on E2 concentration, but antibodies to Pg increase Pg concentration in blood serum of postmenopausal healthy women with low levels of antibodies against benzo[a]pyrene (Bp). Thereby natural occurrence antibodies to Pg inhibit the promotion of breast carcinogenesis.

Immunization against environmental chemical carcinogens: Pro and contra.

The problems of immunoprotection from the environmental chemical carcinogens are discussed. The main experimental argument pro active immunization against carcinogens is a possibility of specific mucosal antibodies (Abs) to inhibit the penetration of carcinogens from environment and to stimulate its excretion with the following decreasing of carcinogen-DNA adducts levels. Hypothesis of cancer immunostimulation after active immunization against carcinogens is based on a high cancer risk in persons with high levels of serum Abs specific to environmental carcinogens coupled with high levels of Abs to endogenous steroids stimulating the proliferation of target cells, for example, Abs to benzo[a]pyrene together with Abs to estradiol.

[Quantitative characteristics of chromosomal aberration frequency in the residents of the regions with different levels of cancer incidences].

We present the results of cytogenetic monitoring of the districts in Kemerovo region, which differ in standardized indices of cancer incidence. It has been shown that residents of the districts with high incidence of malignancies had higher average frequency of metaphases with chromosomal aberrations than the control group (4.06 +/- 0.

Impact of phase composition on water adsorption on inorganic hybrids "salt/silica".

The effect of a "guest-host" interaction on the phase composition and sorption properties of the composite sorbents "salt in a porous host matrix" has been studied. The matrix was a mesoporous silica of KSK type, while the confined salts were CaCl(2), CuSO(4), MgSO(4), and Na(2)SO(4). Both structure and properties of the composites were studied by X-ray diffraction, titration in the pH range of 2-9, differential dissolution, and TG techniques.

[Influence of genetic and phenotypical factors on the efficiency of the vaccination of young children against diphtheria and measles].

The child's sex was shown to influence the character of antibody formation only after immunization against diphtheria with live measles vaccine: girls exhibited stronger reaction to vaccination than boys. Children of different gender were found to have characteristic HLA DR markers of humoral immune response to diphtheria toxoid and measles vaccine. HLA DR7 proved to be the marker of low production of antibodies to diphtheria toxoid and measles vaccine in boys.
