Protective potential of glucagon like peptide 2 (GLP-2) against the neurodegeneration
2019
Neurodegeneration consists in loss of neuron specific types, pattern and distribution, leading to progressive dysfunctions of the central nervous system. Neurodegenerative diseases include diverse pathological conditions, among which Alzheimer’s and Parkinson’s diseases are the most prevalent ones. Alzheimer’s disease is known as a growing dementia, characterized by progressive language, memory, and cognitive loss, while Parkinson’s disease is primarily characterized as a motor disorder. Senile plaques, caused by amyloid β peptide, hyperphosphorylated tau-based neurofibrillary tangles and synapse loss, are the principal pathological hallmarks of Alzheimer’s disease. Amyloid β oligomer forma…
Binding Profiles of Self-Assembled Supramolecular Cages from ESI-MS Based Methodology
2018
Confined molecular environments have peculiar characteristics that make their properties unique in the field of biological and chemical sciences. In recent years, advances in supramolecular capsule and cage synthesis have presented the possibility to interpret the principles behind their self‐assembly and functions, which has led to new molecular systems that display outstanding properties in molecular recognition and catalysis. Herein, we report a rapid method based on ESI‐MS to determine the binding profiles for linear saturated dicarboxylic acids in a series of different cages. The cages were obtained by self‐assembly of modified tris(pyridylmethyl)amine (TPMA) complexes and diamines cho…
Cyclotriveratrylene-Containing Porphyrins
2016
International audience; The C-3-symmetric cyclotriveratrylene (CTV) was covalently bonded via click chemistry to 1, 2, 3, and 6 zinc(II) porphyrin units to various host for C-60. The binding constants, Ka, were measured from the quenching of the porphyrin fluorescence by C-60. These constants vary between 400 and 4000 M-1 and are considered weak. Computer modeling demonstrated that the zinc(II) porphyrin units, [Zn], exhibit a strong tendency to occupy the CTV cavity, hence blocking the access for C-60 to land on this site. Instead, the pincer of the type [Zn]-[Zn] and in one case [Zn]-CTV, were found to be the most probable geometry to promote host-guest associations in these systems.
Impact of Glucose-Lowering Medications on Cardiovascular and Metabolic Risk in Type 2 Diabetes
2020
Type 2 Diabetes Mellitus (T2DM) is associated with a high risk of atherosclerotic cardiovascular (CV) disease. Among the well-known pathophysiologic factors, crucial roles are played by endothelial dysfunction (caused by oxidative stress and inflammation hyperglycemia-linked), increased activity of nuclear factor kB, altered macrophage polarization, and reduced synthesis of resident endothelial progenitor cells. As consequence, a potentially rapid progression of the atherosclerotic disease with a higher propensity to unstable plaque is arguable, finally leading to significantly increased cardiovascular mortality. Main managements are focused on both prevention and early diagnosis, by target…

Hepatīta B kora antigēna veidoto vīrusveidīgo daļiņu modificēšana vakcīnu prototipa izstrādei
2017
DENV vakcīnu izveide balstās galvenokārt, izmantojot dzīvus novājinātus vīrusus. 2015. gadā tika reģistrēta pirmā tetravalenta novājināta denges vīrusa vakcīna. Kā drošāks vakcīnas veids ir subvienību vakcīnas. Daudzsološākais DENV antigēns subvienību vakcīnas izveidē ir apvalka proteīna III domēns. Lai palielinātu antigēna subvienības imunogenitāti, tiek izmantotas vīrusveidīgās daļiņas (VLP) kā svešu antigēnu nesēji. Tā kā VLP ir pašnereplicējošas, tās tiek uzskatītas par drošākiem kandidātiem vakcīnu izveidē, salīdzinot ar dzīviem novājinātiem vīrusiem. Maģistra darba mērķis bija iegūt 2. serotipa denges vīrusa apvalka III domēnu (DV2-III) prezentējošas mutantās HBc VLP. Pētījumā tika pā…
Self-assembly of an iron(ii)-based M5L6 metallosupramolecular cage
2011
A pentanuclear M(5)L(6) coordination cage is self-assembled in solution from a rigid linear heteroditopic phen-tpy ligand and an iron (II) salt.

Spin state switching in iron coordination compounds
2013
The article deals with coordination compounds of iron(II) that may exhibit thermally induced spin transition, known as spin crossover, depending on the nature of the coordinating ligand sphere. Spin transition in such compounds also occurs under pressure and irradiation with light. The spin states involved have different magnetic and optical properties suitable for their detection and characterization. Spin crossover compounds, though known for more than eight decades, have become most attractive in recent years and are extensively studied by chemists and physicists. The switching properties make such materials potential candidates for practical applications in thermal and pressure sensors …
