Darbā apkopota informācija par poliprenolu liposomālā uztura bagātinātāja “SuperCell” lietošanas ietekmi uz maratonu un pusmaratonu skrējējiem - amatieriem. Lai izpētītu poliprenolu efektivitāti fiziskās slodzes laikā, tika pētīti divu maratona skrējēju grupu asins bioķīmiskie parametri. Pētījuma dalībnieki bija 22 vīriešu dzimuma sportisti vecumā no 25 līdz 41 gadam, kuri tika sadalīti kontroles grupā (nelietoja poliprenolus) un produktu grupā - lietoja 30 mg poliprenolu liposomu mīkstā želatīna kapsulās 3 reizes dienā 4 ± 1 dienas pirms skrējiena. Pētījuma rezultāti parādīja, ka produktu grupai statistiski nozīmigi (p<0,05) tika izmainīti eritrocītu, hemoglobīna, limfocītu un laktāta radī…

Poliprenoli (PP) uzrāda antibakteriālu, pretiekaisuma iedarbību, aknu šūnu protektējošu efektu, mazina muskuļu vājumu un iedarbojas uz centrālo nervu sistēmu (Zhang, 2015). Darba mērķis bija noskaidrot egļu skuju PP ietekmi uz kortizola līmeni un asins bioķīmiskajiem marķieriem. Rezultāti liecina, ka vienas nedēļas PP lietošana (60mg/dienā) ir droša un samazina kortizola koncentrāciju, kā arī spēj ietekmē noteiktus asins bioķīmiskos marķierus asinīs, salīdzinot ar kontroles grupu, nepārsniedzot noteiktās normas robežas.

Dažādu poliprenolu un doliholu identifikācija un doliholu līmeņu salīdzināšana žurku muskuļos un aknās

2016

Latvijā ir augsta saslimstība ar sirds un asinsvadu slimībām un mirstība no tām (55%). Šo slimību ārstēšanā tiek izmantoti statīni jeb HMG CoA reduktāzes inhibitori. Darbojoties kā HMG CoA reduktāzes inhibitori, statīni nobloķē mevalonskābes sintēzi un visu no tās bioķīmiski atvasināto savienojumu rašanos, tai skaitā Q10, poliprenolu un doliholu sintēzi, kas varētu ietekmēt blaknes. Darba mērķis ir izpētīt, kāda tipa doliholi atrodas žurku muskuļos un aknās, izmērīt to līmeņus un noskaidrot A/s Biolat ražotā poliprenolu preperāta sastāvu ar lidojuma laika (TOF) metodi un hromatogrāfiju. Iegūtie rezultāti liecina, ka jāturpina darbs pie metodes optimizēšanas: jāuzlabo ekstrahēšanas un attīrī…

L’organisation des circuits courts par les intermédiaires.

2016

The dissertation deals with the institutionalisation of proximity in agri-food markets and the place occupied in this process by non-economic intermediaries (employees of associations, researchers, members of staff from the ministry of Agriculture, advisers of the chambers of agriculture). By varying the scales of investigation, from the national to the departmental level, and by articulating qualitative and quantitative methods, this work points out the paradox that constitute the development of those intermediary agents, as proximity is progressively defined and objectified as a virtuous component of the merchant relationship. On the basis of a sociology of merchant institutions attentive…

Improvements in Rational Design Strategies of Inulin Derivative Polycation for siRNA Delivery.

2016

The advances of short interfering RNA (siRNA)-mediated therapy provide a powerful option for the treatment of many diseases, including cancer, by silencing the expression of targeted genes involved in the progression of the pathology. On this regard, a new pH-responsive polycation derived from inulin, Inulin-g-imidazole-g-diethylenetriamine (INU-IMI-DETA), was designed and employed to produce INU-IMI-DETA/siRNA "Inulin COmplex Nanoaggregates" (ICONs). The experimental results showed that INU-IMI-DETA exhibited strong cationic characteristics and high solubility in the pH range 3-5 and self-aggregation triggered by pH increase and physiological salt concentration. INU-IMI-DETA showed as well…

Hyaluronan-coated polybenzofulvene brushes as biomimetic materials

2016

Hyaluronic acid (HA) forms pericellular coats in many cell types that are involved in the early stages of cell adhesion by interacting with the CD44 receptor. Based on the largely recognized overexpression of the CD44 receptor in tumor tissues, a polybenzofulvene molecular brush has been enveloped into hyaluronan shells to obtain a tri-component polymer brush (TCPB) composed of intrinsically fluorescent backbones bearing nona(ethylene glycol) arms terminated with low molecular weight HA macromolecules. The nanoaggregates obtained in TCPB water dispersions were characterized on the basis of dimensions, zeta potential, and in vitro cell toxicity. This biomimetic multifunctional material beari…

Hospitalization and mortality among the elderly exposed to polytherapy and at risk of adverse drug reactions

2017

The increase in comorbidities due to an aging population determines a marked increase in the use of drugs (polypharmacy), which in turn carries a high risk of drug-drug interactions. This Paper will analyze the relationship between exposure to adverse drug interactions, and hospitalization and mortality in a cohort of elderly patients, living in a local Health Unit in Palermo, Italy. These patients were exposed to drugs whose concurrent use is contraindicated during the period 1.1.2014 - 30.12.2014. After a description of the most common drugs involved in adverse reactions, an evaluation of the extent of hospitalization and mortality will be performed. The results will demonstrate that ther…

Invasive alien species – potential cheap resources of plant substances for medicinal use

2018

Some alien species demonstrate rather invasive behaviour. They have high tolerance of various habitat conditions and potent propagation ability. They not only over-compete the local vegetation but suppress the seed development of the native plants. In the newly invaded habitats they might not have suitable herbivores to control their populations. The only effective enemy might be Homo sapiens. Humans are known with their destructive power once an object has become significant for industrial utilization. The aim of this study is to review research data and reveal the potential of Ambrosia artemisiifolia L., Erigeron canadensis L., Xanthium strumarium L. and Dittrichia graveolens (L.) W. Greu…
