A second triclinic polymorph of (1-ammonio-1-phosphono­eth­yl)phospho­nate

The asymmetric unit of the second polymorph of the title compound, C2H9NO6P2, contains one mol­ecule existing as a zwitterion. The N atom of the ammonio group is protonated and one of the phospho­nic acid groups is deprotonated. Bond lengths and angles are similar in both polymorphs. Besides the differences in cell parameters, the most significant structural difference between this structure and that of the first polymorph [Dudko, Bon, Kozachkova, Tsarik & Pekhno (2008 ▶), Ukr. Khim. Zh. 74, 104–106] is the presence of strong symmetric hydrogen bonds between neighbouring phospho­nate groups. H atoms involved in these hydrogen bonds are located at inversion centres and O⋯O distances are observed in the range 2.458 (5)–2.523 (5) Å. These bonds and additional O—H⋯O and N—H⋯O hydrogen bonds inter­link the mol­ecules, giving a three-dimensional supromolecular network

trans-Bis[(1-ammonio­pentane-1,1-di­yl)diphospho­nato-κ2 O,O′]diaqua­copper(II)

In the title compound, [Cu(C5H14NO6P2)2(H2O)2], the CuII atom occupies a special position on an inversion centre. It exhibits a distorted octa­hedral coordination environment consisting of two O,O′-bidentate (1-ammonio­pentane-1,1-di­yl)diphospho­nate anions in the equatorial plane and two trans water mol­ecules located in axial positions. The ligand mol­ecules are coordinated to the CuII atom in their zwitterionic form via two O atoms from different phospho­nate groups, creating two six–membered chelate rings with a screw-boat conformation. The CuO6 coordination polyhedron is strongly elongated in the axial direction with 0.6 Å longer bonds than those in the equatorial plane. Intra­molecular N—H⋯O hydrogen bonding helps to stabilize the mol­ecular configuration. The presence of supra­molecular —PO(OH)⋯O(OH)P— units parallel to (100) and other O—H⋯O and N—H⋯O hydrogen bonds establish the three-dimensional set-up

Diaqua­bis­(dihydrogen 3-aza­niumyl-1-hy­droxy­propyl­idene-1,1-di­phos­phon­ato-κ2 O,O′)cobalt(II)

The asymmetric unit of title compound, [Co(C3H10NO7P2)2(H2O)2], contains one half-mol­ecule of the complex. The CoII atom is located on an inversion centre and displays a distorted octa­hedral coordination geometry defined by four O atoms of two 3-aza­niumyl-1-hy­droxy­propyl­idene-1,1-bis­phospho­nato ligands in the equatorial plane and two water mol­ecules located in axial positions. The ligand mol­ecules, which exist in a zwitterionic state, form two six-membered chelate rings with chair conformations. In the crystal, mol­ecules are inter­linked by O—H⋯O and N—H⋯O hydrogen bonds, forming a three-dimensional supra­molecular structure

Bis[(1-ammonio­ethane-1,1-di­yl)diphospho­nato-κ2 O,O′]diaqua­nickel(II) nona­hydrate

The title compound, [Ni(C2H8NO6P2)2(H2O)2]·9H2O, exhibits a slightly distorted octa­hedral coordination environment around the NiII atom. It contains two mol­ecules of 1-amino­­ethyl­idenediphospho­nic acid in the zwitterionic form, coord­inated via O atoms from two phospho­nate groups and creating two six-membered chelate rings. Two water mol­ecules in cis positions complete the coordination environment of the NiII atom. The title compound contains nine partly disordered solvent water mol­ecules, which create a three-dimensional network of strong O—H⋯O and N—H⋯O hydrogen bonds

UCRAID (Ukrainian Citizen and refugee electronic support in Respiratory diseases, Allergy, Immunology and Dermatology) action plan

Eight million Ukrainians have taken refuge in the European Union. Many have asthma and/or allergic rhinitis and/or urticaria, and around 100,000 may have a severe disease. Cultural and language barriers are a major obstacle to appropriate management. Two widely available mHealth apps, MASK-air® (Mobile Airways Sentinel NetworK) for the management of rhinitis and asthma and CRUSE® (Chronic Urticaria Self Evaluation) for patients with chronic spontaneous urticaria, were updated to include Ukrainian versions that make the documented information available to treating physicians in their own language. The Ukrainian patients fill in the questionnaires and daily symptom-medication scores for asthma, rhinitis (MASK-air) or urticaria (CRUSE) in Ukrainian. Then, following the GDPR, patients grant their physician access to the app by scanning a QR code displayed on the physician's computer enabling the physician to read the app contents in his/her own language. This service is available freely. It takes less than a minute to show patient data to the physician in the physician's web browser. UCRAID—developed by ARIA (Allergic Rhinitis and its Impact on Asthma) and UCARE (Urticaria Centers of Reference and Excellence)—is under the auspices of the Ukraine Ministry of Health as well as European (European Academy of Allergy and Clinical immunology, EAACI, European Respiratory Society, ERS, European Society of Dermatologic Research, ESDR) and national societies

Balancing repair and tolerance of DNA damage caused by alkylating agents

Alkylating agents constitute a major class of frontline chemotherapeutic drugs that inflict cytotoxic DNA damage as their main mode of action, in addition to collateral mutagenic damage. Numerous cellular pathways, including direct DNA damage reversal, base excision repair (BER) and mismatch repair (MMR), respond to alkylation damage to defend against alkylation-induced cell death or mutation. However, maintaining a proper balance of activity both within and between these pathways is crucial for a favourable response of an organism to alkylating agents. Furthermore, the response of an individual to alkylating agents can vary considerably from tissue to tissue and from person to person, pointing to genetic and epigenetic mechanisms that modulate alkylating agent toxicity

Consortium topical and fabric links and their role in biotic diversity preservation

Attention is paid to the necessity of studying of topical, trophic, fabric and foric links during consortium structure analysis and prognosis of its future. It has been concluded that consortium is a focus of individual, population and ecosystem diversity. Consortium destruction leads to the loss of biotic diversity

Key species as centers of the biodiversity development

In this article, the interrelation of key species with the biotic diversity in the ecosystems is considered. Attention is drawn to actual scientific problem of the biodiversity research of all variety forms and on all of its levels. The further humankind existence depends on the solution of the problem. It is possible to conduct biodiversity research in two aspects: integral (global) and differential (local). These aspects differ in final results and their outlay sources for the realization. Knowledge of total biodiversity on the planet is a result of global approach, and the knowledge of certain groups of organisms (taxonomic, ecological etc.) for the certain territory is the result for local approach. Both of them substantially differ in methodology approaches. One of the effective methodology approaches for study of the local biodiversity is a study of key species’ role in its development. In this work, the following categorization of key species is accepted: ecological, protective, economical, social, adventitious etc. The examples of the role of key species in the development of species diversity in ecosystems are reviewed. In particular, it was ascertained that such ant species as Lasius niger and L. flavus settle abandoned arable lands in mass, create specific micro-landscapes there, and influence positively on the development and growth of some grass plant species. European mole Talpa europaea changes soil structure significantly and has a huge influence on plant species diversity due to its burrowing activity. Such species of amphibians as Fire-bellied toad Bombina bombina, Crested newt Triturus cristatus, Moor frog Rana arvalis, Spadefoot Pelobates fuscus, Green toad Bufotes viridis etc. are worthy of notice as the indicators of environment (habitat) status. The attention is drawn to the consortive analysis as the most effective instrument in the research of interrelations between key species and biodiversity. The analysis is focused on the research of obligate and facultative organisms of different taxonomic groups which are functioning as a whole
