Evaluation of the microbiological quality of some dairy products
Authors: Laslo É. , György É. 
Published: January 2019

Abstract
Owing to their nutrient composition, dairy products ensure a favourable environment for different microorganisms. In our study, we investigated the microbiological quality of 22 different commercially available dairy products obtained from local stores and the open-air public market. Among the studied samples four were salty type soft cheese, two were fresh cheese, one was soft cheese (Mascarpone), one was feta-like cheese (Telemea), five were varieties of processed cheese, one was mozzarella, one was a semi-hard cheese, one was smoked cheese, five were cottage cheese, and one was a dairy spread. Samples were evaluated for the presence of Pseudomonas sp., total coliforms, Escherichia coli, Salmonella sp., Staphylococcus aureus, Bacillus cereus and Clostridium perfringens, yeast, and microscopic fungi.
Contamination level of the evaluated dairy products varied widely. Among the dairy samples one salty soft cheese, a processed cheese and one cottage cheese were the most contaminated, while low microbiological load was detected in the other samples.

Published: January 2019

Abstract

Apis cerana is an Eastern honeybee species distributed throughout Asia and closely related to the Western honeybee species Apis mellifera distributed across all of Africa, Europe and Western Asia, and subdivided into thirty confirmed subspecies. Currently, A. cerana is an endangered bee species in contrast to A. mellifera. We sequenced and annotated the complete mitochondrial genome of A. cerana from the Jeollanam-do province of South Korea and uploaded to the DDBJ/Genbank database(AP018431). MtDNA sequence is 15.925 bp long, has 84% AT-content and 16% GC-content and contains 22 tRNA genes, 13 protein-coding genes, two ribosomal RNA genes, one AT-rich region and four non-coding intergenic regions (NC1-4). All protein-coding genes are started by ATT and ATG codons, except the genes ATP8 and ND4, which started by ATC and ATA, respectively, and are stopped by the common codons TAA and TAG. A comparative analysis of the whole mtDNA sequences of A. cerana from Korea and Taiwan, A. c. cerana from China and A. c. japonica from Japan showed that the genetic divergence of the Korean A. cerana sample from subspecies A. c. cerana (2.57%) and A. c. japonica (2.58%) matched to the level of genetic divergence of mtDNA between animal subspecies (0.8-8%). Based on the comparative analysis of complete mtDNA (~16,000 bp), two nuclear gene VG and EF1- α sequences (~8,000 bp) and morphological measurements (six parameters), we assumed that Korean A. cerana, Chinese A. c. cerana and Japanese A. c. japonica are different subspecies at an early stage of sub-speciation and could be called further as subspecies of Apis cerana koreana.
Economic Value of Pollination Service of Agricultural Crops in Ethiopia: Biological Pollinators
Authors: Alebachew Getachew Worku 
Published: January 2019

Abstract
The most important ecosystem service for sustainable crop production is pollination, the mutualistic interaction between plants and animals. Honeybees are being indispensable role in this process. The total economic value of crop pollination worldwide has been estimated at €153 billion annually. Animal pollination of agricultural crops is provided by both managed and wild pollinators. The aim of this study was to determine the economic value of pollination services and vulnerability of Ethiopian agriculture in the face of pollinator decline. An improved approach to determine the economic value of pollination (EVP) services is applied to multiply a crop’s total value by a coefficient between zero and one representing the crop’s dependency on pollination services for production. The potential production value loss due to lack of pollinators is also computed as the ratio of EVP to economic production value. Then EVP was $ 815.2 million dollars and vulnerability of Ethiopian agriculture due to lack of pollinators 16% in the 2015/16 crop production season. The regional state of Oromia benefited the most followed by the regional states of Amhara and South Nation Nationality People (SNPP). Coffee, the leading crop, has the highest EVP in the country followed by Faba beans and Nug (Guizotia abyssinica). Ethiopia has highly benefited from biological pollinators, so protecting them has significant role in the country’s economy. Most crops in Ethiopia have no pollination dependency ratio and some minor crop has no production data, incorporating them possible to better estimation of EVP service for the future.

Published: January 2019

Abstract
High molecular weight glutenin subunits (HMW-GS) of wheat are important factors in the determination of bread-making quality. They are responsible for elasticity and polymer formation of wheat dough. In the present study, 43 winter and 40 spring common wheat (Triticum aestivum L.) cultivars originated from Estonia, Belarus, Finland, Denmark, France, Germany, the Great Britain, Latvia, Lithuania, the Netherlands, Norway, Poland, Russia, Sweden, and New Zealand were characterised for Glu-A1 and Glu-D1 allelic composition using PCR method. Analyses were conducted with one DNA marker for identification of Glu-D1 allele encoding subunit Dx5, three DNA markers for Glu-A1 Ax1, Ax2* and AxNull subunits. It was determined that 32 (74.4%) winter and 35 (83.3%) spring cultivars had allele Glu-D1d, and 23 (53.5%) winter and 33 (78.6%) spring — Glu-A1a or Glu-A1b alleles, which have positive effect on dough properties. Polymorphism at Glu-A1 locus was detected in 15 cultivars, and 9 cultivars were polymorphic for locus Glu-D1. The obtained results were compared with published SDS-PAGE data. Complete or partial agreements were found for 78.1% of Glu-A1 and 70.6% of Glu-D1 alleles. Rapid and accurate identification of wheat Glu-1 alleles by molecular markers can be used for selection of wheat genotypes with good bread-making potential.

Abstract
The aim of this study was to evaluate treatment of patients with moderate and severe heart failure (HF) who were resistant to pharmacotherapy in Latvia and to assess the cardiac resynchronisation therapy (CRT) by exploring the predisposing factors which provides CRT efficacy. We accomplished prospective analysis of left ventricle ejection fraction (LVEF) and other parameter changes 12 and 24 months after CRT device implantation, dividing the population into two groups: responders — to whom LVEF improvement was ≥10% and non-responders where ≥ 10% LVEF improvement was not achieved. The study included 50 chronic HF patients with preserved sinus rhythm, who underwent CRT device implantation in Latvia at the Pauls Stradiņš Clinical University Hospital from June 2009 to March 2012. In the group of patients where 12 and 24 months after CRT device implantation LVEF improvement ≥10% was achieved, there were statistically significantly more patients with left bundle branch block (LBBB) QRS morphology, wider QRS complex, nonischemic genesis of HF, and normal systolic blood pressure. Patients with LVEF improvement had more pronounced ventricular dyssynchrony measured by Echo before CRT device implantation and, accordingly, the CRT mode was programmed as left ventricle paced before right ventricle and close to 100% biventricular pacing was achieved and the patient was female.

Stable assessment of the quality of similarity algorithms of character strings and their normalizations
Authors: Znamenskij Sergej Vital'evich 
Published: January 2019

The choice of search tools for hidden commonality in the data of a new nature requires stable and reproducible comparative assessments of the quality of abstract algorithms for the proximity of symbol strings. Conventional estimates based on artificially generated or manually labeled tests vary significantly, rather evaluating the method of this artificial generation with respect to similarity algorithms, and estimates based on user data cannot be accurately reproduced.
A simple, transparent, objective and reproducible numerical quality assessment of a string metric. Parallel texts of book translations in different languages are used. The quality of a measure is estimated by the percentage of errors in possible different tries of determining the translation of a given paragraph among two paragraphs of a book in another language, one of which is actually a translation. The stability of assessments is verified by independence from the choice of a book and a pair of languages.
The numerical experiment steadily ranked by quality algorithms for abstract character string comparisons and showed a strong dependence on the choice of normalization.

Fourteen compounds were isolated from acetone extracts of three species of seaweeds (Eucheuma serra, a red seaweed, Halimeda opuntia, a green seaweed, and Hydroclathrus clathratus, a brown seaweed) using bioautographic TLC methods and identified using GC-MS. From Eucheuma serra were isolated 8 compounds (3 fatty acids, 3 steroids, and 2 aldehyds). Only two compounds of fatty acid camefrom Halimeda opuntia, whereas Hydroclathrus clathratus produced 6 compounds (4 fatty acids, one compound each of steroid and ether). All isolated single compoundswere tested for their antibacterial activities by the agar diffusion method against the Gram-positive bacteria Staphylococcus aureus, Bacillus subtilis and Streptococcusfaecalis, and the Gram-negative bacteria Echerichia coli, Pseudomonas aeruginosa and Salmonella typhimurium. All 14 compounds showed activity against Gram-positivebacteria, especially Bacillus subtilis, and only 2 compounds showed activity against Gram-negative bacteria Escherichia coli. Nine compounds showed activity against Staphylococcus aureus, and 4 compounds showed activity against Streptococcusfaecalis. All compounds were not active against Pseudomonas aeruginosa andSalmonella typhimurium bacteria. This study indicated that there is indeed a diversityboth in kinds and in molecular structures of the antibacterial substances.

Effects of Plant Species, Insecticide, and Exposure Time On the Efficacy Of Barrier Treatments Against Aedes albopictus
Authors: McMillan Benjamin E. , Bova Jake E. , Brewster Carlyle C. , Gallagher Nicola T. , Paulson Sally L. 
Published: January 2019

ABSTRACT
The effect of 5 plant species (arborvitae [Thuja occidentalis], boxwood [Buxus sp., Japanese honeysuckle [Lonicera japonica], rhododendron [Rhododendron sp.], and zebra grass [Miscanthus sinensis]) and 2 rates of lambda-cyhalothrin (3.13 ml and 6.25 ml active ingredient [AI]/liter) on knockdown (1 h) and mortality (24 h) of adult female Aedes albopictus was evaluated over an 8-wk period. A significant difference in knockdown was observed between the 2 rates of lambda-cyhalothrin on the 5 plant species, with the highest proportion of knockdown observed on zebra grass and rhododendron treated at the higher rate. Although mortality was ≥60% and 85% on the 5 plant species at the low and high rates of lambda-cyhalothrin, respectively, a significant difference between the 2 rates was only observed on boxwood and Japanese honeysuckle (P &lt; 0.0001). We also tested the residual toxicity of 3 barrier sprays (lambda-cyhalothrin, bifenthrin, and deltamethrin) and evaluated the efficacy of a short (5-min) exposure to the insecticides on knockdown and mortality of adults over time. Significantly higher knockdown was observed with lambda-cyhalothrin compared with bifenthrin and deltamethrin (P &lt; 0.0001). Mean knockdown was ∼98%, 92%, and 20% for lambda-cyhalothrin, bifenthrin, and deltamethrin, respectively, at week 2, and ∼98%, 0%, and 44%, respectively, 8 wk after treatments were applied. Adult mortality from the 3 chemical treatments, however, remained above 90% throughout the study. Lastly, the trends in mean proportion of knockdown were similar for mosquitoes exposed for either 5 min or 24 h to the 3 chemicals. An overall decline in mean mortality over time, however, was observed for mosquitoes exposed for 5 min to the chemicals compared with mortality from the 24-h exposure. The results suggest that lambda-cyhalothrin can be an effective barrier spray treatment against Ae. albopictus adults because its efficacy is limited little by plant species, it has long residual toxicity, and it is effective following only 5 min of exposure.

Published: January 2019

Objective: To determine percentages of types A (flat) and B (concave) of the distal tibiofibular joint in patients with ankle fractures or chronic ligament instabilities, with syndesmosis lesions; check the shape of the fixation and position of the fibula in this joint; to identify poor fibular reduction and its frequency in types A and B; patients according to the AOFAS criteria. Methods: 104 patients surgically treated with syndesmosis fixation underwent clinical evaluation using AOFAS functional criteria and tomographic exams to classify the distal tibiofibular joint in types A or B and evaluated the poor position of the fibula in this joint. Results: Distal tibiofibular joint type A was present in 27 ankles and type B in 77. Non-anatomical reduction of the fibula (17 ankles) was more frequent in type A than in type B and more frequent in fractures than in instabilities. The AOFAS score was 91.79 points in the 87 patients with good reduction and 86.76 points in the 17 patients with poor fibula reduction. Conclusion: Distal tibiofibular joint type B was more frequent than type A (p=0.00001); there was poor reduction of the fibula in this joint in 17 ankles (16.34%). Poor fibula reduction was more frequent in fractures than in instabilities (p=0.006). The poor reduction was more constant in type A than in type B, without statistical significance (p=0.34). The AOFAS score was 91.79 points in patients with good reduction and 86.76 points in patients with poor fibula reduction in the distal tibiofibular joint.

Published: January 2019

Objective: The aim of this study is to test the hypothesis that patients with calcaneal fractures who are surgically treated and have Böhler and Gissane angles restored to normal have a faster return to work than patients without restoration of these angles. Calcaneal fractures represent 1-2% of all fractures, and approximately 75% of these are articular, indicating surgical treatment. Joint involvement results in functional limitation and can lead to late complications such as chronic pain, subtalar arthrosis, difficulty walking, and deformities. Methods: Lateral radiographs of the calcaneus of 44 patients who underwent surgical treatment for calcaneal fracture during the period from 2014 to 2016 were analysed to measure the Böhler and Gissane angles and to evaluate the association of their restoration to normal with the time to return to work. Results: Among the patients, 70.2% presented restoration of the Böhler angle and 44.7% presented restoration of the Gissane angle with surgery. The mean time away from work was 8.38 months. A total of 76.6% of patients returned to the same function. Patients who had good fracture reduction had a shorter time to return to work, but this result was not statistically significant. Conclusion: Surgical restoration of angles can positively influence the functional outcomes of patients, but this is not the only variable and thus should not be exclusively used to analyse the functional outcome and time to return to work of patients.
