Sourdough bread preparation using selected lactic acid bacterial starter cultures

The lactic fermentation of cereals is known to improve the food quality through the development of flavor, enhancement of the nutritional value and shelf life, and by removing toxic or antinutritional factors of food products. Lactic acid bacteria (LAB) strains are able to improve the shelf life of several food products. The efficiency of the LAB cultures determined in in vitro assays was confirmed in bread manufacture. The sourbread prepared using 50 per cent yeast and 50 per cent LAB starter (based on cell density) was found to be superior to the conventional bread in textural characteristics, flavor, appearance and even taste. It contained enough protein (10.15%) and the least fat value (7.68%). It scored the highest acceptability index of 81.70. These results point out the advantages of using selected LAB strains as starter cultures for sourdough fermentation

Management of Uterine Fibroid in the Ayurvedic perspective - A Case Study

Uterine fibroids are commonest benign tumor of the uterus. Histologically this tumor is composed of smooth muscle and fibrous connective tissue, so named as uterine leiomyoma, myoma or fibroma. The cause for some of the most common gynecological problems among women presenting to gynecology emergency and outpatient departments. They are often asymptomatic but they can cause a multitude of symptoms such as abnormal uterine bleeding, a feeling of pelvic pressure, urinary incontinence or retention, or pain. Uterine fibroids are a major cause of morbidity in women of a reproductive age (and sometimes even after menopause). There are several factors that are attributed to underlie the development and incidence of these common tumors, but this further corroborates their relatively unknown etiology. The most likely presentation of fibroids is by their effect on the woman’s menstrual cycle and pelvic pressure symptom

Nonrelativistic Chern-Simons Vortices on the Torus

A classification of all periodic self-dual static vortex solutions of the Jackiw-Pi model is given. Physically acceptable solutions of the Liouville equation are related to a class of functions which we term Omega-quasi-elliptic. This class includes, in particular, the elliptic functions and also contains a function previously investigated by Olesen. Some examples of solutions are studied numerically and we point out a peculiar phenomenon of lost vortex charge in the limit where the period lengths tend to infinity, that is, in the planar limit.Comment: 25 pages, 2+3 figures; improved exposition, corrected typos, added one referenc

Comparative Genomics Reveals Adaptation by Alteromonas sp. SN2 to Marine Tidal-Flat Conditions: Cold Tolerance and Aromatic Hydrocarbon Metabolism

Alteromonas species are globally distributed copiotrophic bacteria in marine habitats. Among these, sea-tidal flats are distinctive: undergoing seasonal temperature and oxygen-tension changes, plus periodic exposure to petroleum hydrocarbons. Strain SN2 of the genus Alteromonas was isolated from hydrocarbon-contaminated sea-tidal flat sediment and has been shown to metabolize aromatic hydrocarbons there. Strain SN2's genomic features were analyzed bioinformatically and compared to those of Alteromonas macleodii ecotypes: AltDE and ATCC 27126. Strain SN2's genome differs from that of the other two strains in: size, average nucleotide identity value, tRNA genes, noncoding RNAs, dioxygenase gene content, signal transduction genes, and the degree to which genes collected during the Global Ocean Sampling project are represented. Patterns in genetic characteristics (e.g., GC content, GC skew, Karlin signature, CRISPR gene homology) indicate that strain SN2's genome architecture has been altered via horizontal gene transfer (HGT). Experiments proved that strain SN2 was far more cold tolerant, especially at 5°C, than the other two strains. Consistent with the HGT hypothesis, a total of 15 genomic islands in strain SN2 likely confer ecological fitness traits (especially membrane transport, aromatic hydrocarbon metabolism, and fatty acid biosynthesis) specific to the adaptation of strain SN2 to its seasonally cold sea-tidal flat habitat

Orthogonal methods based ant colony search for solving continuous optimization problems

Research into ant colony algorithms for solving continuous optimization problems forms one of the most significant and promising areas in swarm computation. Although traditional ant algorithms are designed for combinatorial optimization, they have shown great potential in solving a wide range of optimization problems, including continuous optimization. Aimed at solving continuous problems effectively, this paper develops a novel ant algorithm termed "continuous orthogonal ant colony" (COAC), whose pheromone deposit mechanisms would enable ants to search for solutions collaboratively and effectively. By using the orthogonal design method, ants in the feasible domain can explore their chosen regions rapidly and e±ciently. By implementing an "adaptive regional radius" method, the proposed algorithm can reduce the probability of being trapped in local optima and therefore enhance the global search capability and accuracy. An elitist strategy is also employed to reserve the most valuable points. The performance of the COAC is compared with two other ant algorithms for continuous optimization of API and CACO by testing seventeen functions in the continuous domain. The results demonstrate that the proposed COAC algorithm outperforms the others

Production of bioethanol from starchy tuber (amorphophallus commutatus) and antimicrobial activity study of its extracts

Bio-fuels have been regaining popularity due to the rising price of oil, along with the growing concern about global warming caused by carbon dioxide emissions. Bio-fuels are processed from plant resources and are mostly made up of cellulose, which is one of the toughest materials. If cellulose can be turned into bio-fuel, it could be more efficient than other commercially available fuels starchy tuber. The of this study is on bio-ethanol production from starchy tuber. The comparative study was done between biological and chemical processes for the bio-ethanol production using Amorphophallus tubers. Amorphophallus commutatus species was selected because it shows higher starch content as per starch estimation. Tuber was collected in the lab and pre-treatment was given; followed by slurry was prepared and hydrolyzed by using fungal culture Aspergillus and Trichoderma. Three different conditions were maintained as two samples contain both fungal cultures, and one was having normal pH and temperature, and other was at normal temperature having pH 6, and third having only Aspergillus species and normal temp and pH. Hydrolysis was done by saccharification method. After hydrolysis sample is filtered and all three samples allows for fermentation process by using yeast (Saccharomyces cerevisiae) process is carried out for 12 to 15 days after fermentation the fermented sample was distilled by Soxlet Extraction method and lastly the sample was estimated for alcohol estimation by using specific gravity method. Two samples showed 11% alcohol content and third one shows 12% content when compared with alcoholometry table. Antimicrobial activity was also studied by using three extracts such as before hydrolysis, after hydrolysis and after fermentation against four types of organism’s two species Salmonella and S. aureus shows positive result while E. coli and Serratia sp. showed negative result. Results indicate that chemical process more productive compared to biological process. However, biological process is eco-friendly. It is also cost-effective. It can be produced on large scale for production of bio-ethanol

Détection voltamétrique des catécholamines dans le bulbe olfactif du rat

La voltamétrie différentielle sur impulsions normales (D.N.P.V.) associée à une fibre de carbone traitée électrochimiquement a été conçue pour la détermination des catécholamines. Une étude in vitro a permis de mettre au point un traitement électrochimique pour la détection des catécholamines qui a amplement amélioré les performances de l'électrode en termes de sélectivité, de sensibilité et de stabilité de la réponse. In vivo, l'électrode ainsi traitée a servi pour l'évaluation de très faibles concentrations (10.7 à 10.8 M) des catécholamines extracellulaires au niveau du bulbe olfactif du rat.Voltammetric detection of catecholamines in the rat olfactory bulbDifferential normal pulse voltammetry (DNPV) associated to electrochemically treated carbon fiber electrode has been used for catecholamines determination.

Evaluation of fluralaner and afoxolaner treatments to control flea populations, reduce pruritus and minimize dermatologic lesions in naturally infested dogs in private residences in west central Florida USA. Parasites & Vectors, 9, 11. doi:10.1186/s13071-016-1654-7Background: A study was conducted to evaluate and compare the effectiveness of two different oral flea and tick products to control flea infestations, reduce pruritus and minimize dermatologic lesions over a 12 week period on naturally infested dogs in west central FL USA. Methods: Thirty-four dogs with natural flea infestations living in 17 homes were treated once with a fluralaner chew on study day 0. Another 27 dogs living in 17 different homes were treated orally with an afoxolaner chewable on day 0, once between days 28-30 and once again between days 54-60. All products were administered according to label directions by study investigators. Flea populations on pets were assessed using visual area counts and premise flea infestations were assessed using intermittent-light flea traps on days 0, 7, 14, 21, and once between days 28-30, 40-45, 54-60 and 82-86. Dermatologic assessments were conducted on day 0 and once monthly. Pruritus assessments were conducted by owners throughout the study. No concurrent treatments for existing skin disease (antibiotics, anti-inflammatories, anti-fungals) were allowed. Results: Following the first administration of fluralaner or afoxolaner, flea populations on pets were reduced by 99.0 % and 99.3 %, respectively within 7 days. Flea populations on the fluralaner treated dogs were 0 (100 % efficacy) on days 54-60 and 82-86 after the administration of a single dose on day 0. Administration of 3 monthly doses of afoxolaner reduced flea populations by 100 % on days 82-86. Flea numbers in indoor-premises were markedly reduced in both treatment groups by days 82-86, with 100 % and 98.9 % reductions in flea trap counts in the fluralaner and afoxolaner treatment groups, respectively. Marked improvement was observed in FAD lesion scoring, Atopic Dermatitis lesions scoring (CADESI-4) and pruritus scores with both formulations. Conclusions: In a clinical field investigation conducted during the summer of 2015 in subtropical Florida, a single administration of an oral fluralaner chew completely eliminated dog and premises flea infestations and markedly reduced dermatology lesions and pruritus. Three monthly doses of the afoxolaner chewable also eliminated flea infestations in dogs, markedly reduced premises' flea populations and similarly improved dermatology lesions and pruritus

Solving a Coupled Set of Truncated QCD Dyson-Schwinger Equations

Truncated Dyson-Schwinger equations represent finite subsets of the equations of motion for Green's functions. Solutions to these non-linear integral equations can account for non-perturbative correlations. A closed set of coupled Dyson-Schwinger equations for the propagators of gluons and ghosts in Landau gauge QCD is obtained by neglecting all contributions from irreducible 4-point correlations and by implementing the Slavnov-Taylor identities for the 3-point vertex functions. We solve this coupled set in an one-dimensional approximation which allows for an analytic infrared expansion necessary to obtain numerically stable results. This technique, which was also used in our previous solution of the gluon Dyson-Schwinger equation in the Mandelstam approximation, is here extended to solve the coupled set of integral equations for the propagators of gluons and ghosts simultaneously. In particular, the gluon propagator is shown to vanish for small spacelike momenta whereas the previoulsy neglected ghost propagator is found to be enhanced in the infrared. The running coupling of the non-perturbative subtraction scheme approaches an infrared stable fixed point at a critical value of the coupling, alpha_c approximately 9.5.Comment: 23 pages, 6 figures, LaTeX2
