Opis:
In the present study, enzyme-resistant dextrin, prepared by heating of potato starch in the presence of hydrochloric (0.1% dsb) and citric (0.1% dsb) acid at 130ºC for 3 h (CA-dextrin), was tested as a source of carbon for probiotic lactobacilli and bifidobacteria cultured with intestinal bacteria isolated from feces of three healthy 70-year old volunteers. The dynamics of growth of bacterial monocultures in broth containing citric acid (CA)-modified dextrin were estimated. It was also investigated whether lactobacilli and bifidobacteria cultured with intestinal bacteria in the presence of resistant dextrin would be able to dominate the intestinal isolates. Prebiotic fermentation of resistant dextrin was analyzed using prebiotic index (PI). In co-cultures of intestinal and probiotic bacteria, the environment was found to be dominated by the probiotic strains of Bifidobacterium and Lactobacillus, which is a beneficial effect.

Opis:
This paper addresses the polar profile of ancient proteins using a comparative study of amino acids found in 25 000 000-year-old shells described in Abelson's work. We simulated the polar profile with a computer platform that represented an evolutionary computational toy model that mimicked the generation of small proteins starting from a pool of monomeric amino acids and that included several dynamic properties, such as self-replication and fragmentation-recombination of the proteins. The simulations were taken up to 15 generations and produced a considerable number of proteins of 25 amino acids in length. The computational model included the amino acids found in the ancient shells, the thermal degradation factor, and the relative abundance of the amino acids observed in the Miller-Urey experimental simulation of the prebiotic amino acid formation. We found that the amino acid polar profiles of the ancient shells and those simulated and extrapolated from the Miller-Urey abundances are coincident.

Opis:
The polymerization of amino acids under anhydrous prebiotic conditions was first studied several decades ago. Here we use a stochastic model stressing the relevant role of the polarity of amino acids in the formation of oligopeptides in a prebiotic milieu. Our goal is to outline the predominance of co-polypeptides over homo-polypeptides, resulting not only from the randomness, but also from polarity properties of amino acids. Our results conclude that there was a higher probability of the formation of co-polypeptides than of homo-polymers. Besides, we may hypothesize that the former would have a more ample spectrum of possible chemical functions than homo-polypeptides.

Opis:
Prebiotics are defined as selectively fermented food ingredients that induce specific changes in the composition and/or activity in the gastrointestinal microbiota beneficial to the host well-being and health. The aim of the presented experiment was to investigate the effect of a prebiotic applied alone or in combination with Hyppocastani extractum siccum, and Lini oleum virginale in rats with dimethylhydrazine induced colon cancer. Wistar albino rats were fed high fat diet supplemented with the prebiotic alone or in combination with Horse chestnut and flaxseed oil. The activity of faecal glycolytic enzymes, lipid parameters, bile acids, short chain fatty acids and counts of coliforms and lactobacilli were determined. Treatment with the prebiotic alone and in combination with selected substances significantly decreased the activity of glycolytic bacterial enzyme β-glucuronidase (P<0.001) and increased activities of β-galactosidase and β-glucosidase. Bile acids concentration was significantly decreased (P<0.01) except for the combination of the prebiotic with Horse chestnut. The prebiotic alone decreased the lipid parameters (P<0.001) and enhanced production of short chain fatty acids. Application of prebiotic and bioactive natural substances significantly reduced number of coliforms (P<0.05). Prebiotic alone significantly increased the count of lactobacilli (P<0.05). These results show that prebiotics have a protective effect and may be the useful for colon cancer prevention and treatment.

Opis:
Radon in the environment of early Earth was present in sites, determined by location of deposits of uranium, in very different geological formations. According to the decay of uranium-238, the total production of radon at the beginnings was twice as high as now and was continuously diminishing to the present levels. This nuclide could not play as big a role as do radioactive elements connected with the presence of high concentration of 235U, which was high enough in some places to give rise to formation of natural nuclear fission reactors (e.g. Oklo phenomenon in Africa). The main role of ionizing radiation in prebiotic chemistry and biological evolution was played by low LET (linear energy transfer) radiations, as deep penetrating sources of external energy. High LET radiations are of low penetration and could act only superficially. Radon is an exception, due to its easy transfer in the air. Therefore, it could play a role already in the cases of these early organisms which exhibited the gaseous exchange of chemical compounds with the surrounding atmosphere. The action was destructive, but, on the other hand, was also mutagenic. Nevertheless, the general quantitative effect of radon on the global scale could not be larger than of other radioactive nuclides. Presented considerations are part of the chapter by the present author on the role of nuclear and radiation chemistry in astrobiology, in the monograph published by American Scientific Publishers [1].

Opis:
The behavior of a slight chiral bias in favor of l-amino acids over d-amino acids was studied in an evolutionary mathematical model generating mixed chiral peptide hexamers. The simulations aimed to reproduce a very generalized prebiotic scenario involving a specified couple of amino acid enantiomers and a possible asymmetric amplification through autocatalytic peptide self-replication while forming small multimers of a defined length. Our simplified model allowed the observation of a small ascending but not conclusive tendency in the l-amino acid over the d-amino acid profile for the resulting mixed chiral hexamers in computer simulations of 100 peptide generations. This simulation was carried out by changing the chiral bias from 1% to 3%, in three stages of 15, 50 and 100 generations to observe any alteration that could mean a drastic change in behavior. So far, our simulations lead to the assumption that under the exposure of very slight non-racemic conditions, a significant bias between l- and d-amino acids, as present in our biosphere, was unlikely generated under prebiotic conditions if autocatalytic peptide self-replication was the main or the only driving force of chiral auto-amplification.

Состояние печени и желчевыводящих путей существенно влияет на функциональную деятельность многих органов и систем, включая характер течения патологических процессов в полости рта. Нарушения антимикробной функции печени могут вызвать развитие или обострить течение стоматологического заболевания, в патогенезе которого решающую роль играет микробный фактор. Цель исследования – изучение влияния на эффективность лечения больных хроническим катаральным гингивитом, развившемся на фоне гепато-билиарной патологии (ГБП), с применением гепатопротектора кверцетина (биофлавоноид, Р-витаминактивное соединение, обладает сильным антиоксидантным, противовоспалительным, адаптогенным действием) и пребиотика инулина, который, стимулируя рост пробиотической микрофлоры, устраняет явления дисбиоза, как правило, развивающиеся при патологии печени. Под наблюдением находилось 85 больных в возрасте 25-49 лет (диагноз – хронический холецистит или желчекаменная болезнь) и 15 здоровых людей такого же возраста (контрольная группа). Все больные с ГБП получали медикаментозное лечение в соответствии с протоколом лечения. Базовое лечение гингивита осуществляли в соответствии с существующими медицинскими стандартами. В дополнение к базовой схеме лечения гингивита 45 пациентов (основная группа) получали кверцетин (80 мг один раз в день) и препарат инулина из цикория (3 г в день). Препараты принимали перорально за 30 минут до еды в течение 7 дней. Остальные 40 пациентов получали только базовую терапию. У больных с гингивитом в сочетании с ГБП снижается саливация, увеличиваются индексы гигиены и гингивита, растет уровень в слюне биохимических маркеров воспаления (эластаза, МДА), микробной обсемененности (уреаза), снижается активность лизоцима и каталазы, а также антиоксидантно-прооксидантный индекс АПИ. Напротив, ферментативный показатель степени дисбиоза увеличивается почти в 12 раз. Назначение в дополнение к базовому лечению пребиотика инулина и гепатопротектора кверцетина существенно улучшает состояние пародонта пациентов и биохимические показатели слюны.
The state of liver and bile passages influences essentially on the functional activity of most organs and systems, including the character of the course of pathologic processes in oral cavity. The disorders in antimicrobic function of liver may cause the development or aggravate the course of the stomatological disease, in the pathogenesis of which the main role is played by microbe factor. The aim of the investigation is to study the influence on the effectiveness of the treatment of patients with chronic catarrhal gingivitis, developed simultaneously to hepatobiliary pathology (HBP), with hepatoprotector quercethin (bioflavonoid, P-vitamin-active compound with strong antioxidant, anti-inflammatory and adaptogenic effect) and prebiotic inulin, which stimulating the growth of prebiotic microflora, removes the phenomena of dysbiosis, that as a rule develop at pathology of liver. 85 patients at the age of 25-49 years old (diagnosis –chronic cholecystitis and cholelithiasis) and 15 healthy people of the same age (the control group) were under observation. All patients with HBP underwent medical treatment according to the treatment protocol. The basic treatment of gingivitis was held in correspondence of the existing medical standards. In addition to the basic scheme of treatment of gingivitis 45 patients (the main group) got quercethin (80 mg once a day) and the preparation of inulin from chicory (3g/day). The preparations were taken per-oral 30 minutes before meal during 7 days. The other 40 patients got only basic therapy. In patients with gingivitis in combination with HBP the salivation decreases, the indices of hygiene and gingivitis increase, the level of biochemical inflammatory markers (elastase, MDA) and microbe insemination (urease) in saliva grows, the activity of lysozyme and catalase as well as antioxidant-prooxidant index API reduces. On the contrary, the enzymatic index of the degree of dysbiosis grows almost by 12 times. The prescription of prebiotic inulin and hepatoprotector quercethin in addition to the basic treatment improves considerably the state of periodontium of the patients and biochemical indices of saliva.

Resistant starches are type of dietary fibers. However, their physiological effects depend on the way they resist digestion in the gastrointestinal tract. The objective of this study was to examine the hypothesis that new type of RS4 preparations, of in vitro digestibility of about 50%, obtained by cross-linking and acetylation, acts as a prebiotic by increasing short chain fatty acids content in cecum digesta. The rats were fed with diet containing pregelatinized, cross-linked and acetylated starches as a main carbohydrate source. Pregelatinized, but not chemically modified, potato starch was used in the composition of the control diet. After two weeks of experiment the increase of short chain fatty acids contents in ceceum digesta was observed. The intake of starch A, cross-linked only with adipic acid, resulted in increase of about 40% of short chain fatty acids content, whereas starch PA cross-linked with sodium trimetaphosphate and adipic acid of about 50%. The utmost twofold increase was observed in the case of the production of propionic acid. In contrast, the content of butyric acid increased (12%) only as an effect of consumption of starch PA and even decreased (about 30%) in case of starch A. Both RS4 starches caused an increase of the production of acetic acid by more than 40%. No changes in serum biochemistry, liver cholesterol and organ weights of rats were stated.

Opis:
Heterocyclic aromatic amines (HCAs) ingested with heat-processed meat can contribute to colon cancer development. Those compounds interact with human intestinal microbiota. Under the research study, the effect was analyzed of IQ, MeIQx, or PhIP amines (each of them at 5 and 25 μg/ml concentration rates) on the growth (24 h cultivation in MRS broth) and survival (incubation for max. 120 h in a phosphate buffer) of four probiotic strains of Lactobacillus. It was found that no concentration level of the HCAs analyzed impacted the growth of bacteria. A higher concentration level of IQ (25 μg/ml) decreased the survival of Lb. casei 0900 after a 24 h period of incubation. MeIQx and PhIP also decreased the survival of Lb. paracasei 0919 after a 24 h period of incubation. Totally, the count of living cells decreased from 109 cfu/ml to 108 cfu/ml. Three strains were absolutely resistant to PhIP during a 120 h period of incubation. The results obtained prove that the probiotic bacteria studied maintain their high viability in the presence of the amines tested and, probably, they can bind together with them in human colon and, then, the aggregated particles are removed from the human body.
Heterocykliczne aminy aromatyczne (HCA) spożywane wraz z termicznie przetworzonym mięsem mogą przyczyniać się do rozwoju raka jelita grubego. W pracy badano wpływ amin IQ, MeIQx oraz PhIP (każda w stężeniu 5 i 25 μg/ml) na wzrost (24-godzinna hodowla w pożywce MRS) i przeżywalność (do 120 h inkubacji w buforze fosforanowym) czterech szczepów probiotycznych z rodzaju Lactobacillus. Zaobserwowano, że żadne z badanych stężeń HCA nie wpływało na wzrost bakterii. Wyższe stężenie IQ (25 μg/ml) obniżało żywotność szczepu Lb. casei 0900 od 24 h inkubacji. Aminy MeIQx i PhIP obniżały żywotność Lb. paracasei 0919 również od 24 h inkubacji. Generalnie liczba żywych komórek obniżyła się z 109 jtk/ml do 108 jtk/ml. Trzy szczepy były całkowicie oporne na obecność PhIP podczas 120 h inkubacji. Uzyskane rezultaty wskazują, że badane szczepy probiotyczne zachowują wysoką żywotność w obecności testowanych amin i prawdopodobnie mogą wiązać się z nimi w jelicie grubym, po czym te zagregowane cząstki usuwane są z organizmu.

Opis:
This paper presents a mathematical-computational toy model based on the assumed dynamic principles of prebiotic peptide evolution. Starting from a pool of amino acid monomers, the model describes in a generalized manner the generation of peptides and their sequential information. The model integrates the intrinsic and dynamic key elements of the initiation of biopolymerization, such as the relative amino acid abundances and polarities, as well as the oligomer reversibility, i.e. fragmentation and recombination, and peptide self-replication. Our modeling results suggest that the relative amino acid abundances, as indicated by Miller-Urey type electric discharge experiments, played a principal role in the early sequential information of peptide profiles. Moreover, the computed profiles display an astonishing similarity to peptide profiles observed in so-called biological common ancestors found in the following three microorganisms; E. coli, M. jannaschii, and S. cereviasiae. The prebiotic peptide fingerprint was obtained by the so-called polarity index method that was earlier reported as a tool for the identification of cationic amphipathic antibacterial short peptides.

Opis:
Microbiological processes in the gastrointestinal tract have great impact on overall animal health. Prebiotic constituents modulate composition and activity of intestinal microflora. Various substances are produced by microorganisms inhabiting large intestine. Short-chain fatty acids are one of the most important end-products of prebiotic fermentation. Prebiotics can improve effectiveness of probiotic supplementation. Some prebiotic substances have also immunomodulatory properties. The aim of this paper was to present the aspects connected with prebiotics in dog nutrition.
