Published: January 2020

Mongolia has been exposed to extreme draught and dry summer for its historical development due to geographical location, climatic condition, surface characteristics and being subject to vulnerable and dry region in terms of ecological system. Besides it, rapid increase in the minerals production has been causing heavy metal pollution in soil, water and plants. Soil pollution is main parameter of environmental pollution and air and water pollution directly depend on it. Main influencing factor of endemic diseases of livestock is chemical ingredient of soil, water and plant. Due to negligent use and disposal of lead containing sources including acid and alkali batteries with lead conductor, vehicle accumulators in last years, environment has been polluted greatly and it becomes the cause of animal poisoning. Heavy metals are dangerous because of their persistence and toxicity. Soil behaves as a sink of heavy metals by aerial deposition of particles emitted by human activities. The aims of this work were to identify the levels of lead in accumulator processing plant and city areas and animals. We have determined lead level in biological samples /livestock blood/ using total reflection X-ray fluorescence spectrometer and compared the results found by the Lead Care II.

In territory of Mongolia growing the 17 species of Stipa type. The more than 3000 samples of 190 species of 46 types of perennial plants stored stored in Forage perennial plant’s Genebank of Research Institute of Animal Husbandry, Mongolia, including more 100 samples of 7 species of Stipa. In recent time necessary to study the seed viability of Stipa species and increase, enrich and renew the seed resources in genebank. We studied the seed viability of needle grass (Stipa L) species, that are collected between 1994-2014from the territory of Mongolia. During the identification of lab germination the samples stored for 24 years did not germinated and 27.2% of samples stored for 20-22 years had only 0.4-8.0% of the germination. Whereas, the samples stored for 15-16 years are germinated in 24.0-96.0%, and samples stored for 4-9 years are 56.5-100.0%, and this results shown that the seed germination rate are depending from the stored years. During the field experiment the 11 samples of 3 species of Stipa were tested in irrigated areas and 13.6-72.7% of them were germinated, 50-100% of them survived to autumn and 83.3-100% of them survived for first winter. From our studies, the needle grass samples are quite good at surviving the winter-spring hardships and the vitality of the already-proven plant survival in the second year of life has increased.

To deepen understandings on changes in mare milk yield and composition along with lactation, physico-chemical characteristics and freshness of raw mare milk this study was conducted. The first trial on the change in mare milk yield and composition was conducted along with different lactation period using 7 adult mares. Milk yield was determined volumetrically after 2 hour foal separation. Hand milking with milk ejection by foal was applied. Milk yield reached at peak in August which corresponds to around 90th days of lactation. Lactose content reaches its max value at 90th day of lactation also and it remains as high as its peak until the milking season ends while the yield was decreased significantly (p≤0.05). Fat and protein contents were gradually decreased to the end of milking season. To conduct quality evaluation of raw mare milk it is vitally important to know physico-chemical characteristics. To clarify did this second trial in comparison with cow milk. Results were indicated that pH value is higher in mare milk and acidity and viscosity is lower in mare milk than those in cow milk. A hygienically obtained mare milk samples were used in this experiment. Acidity, pH and Total Bacterial Counts were monitored with the reference to raw horse milk standard of Mongolia. The results were indicated that hygienically obtained mare milk can be kept for 12 hours at room temp. In case of refrigerated condition it kept its acceptable freshness up 10 days of storage.

Study on realtionship between seed germination and antioxidant enzyme activity
Authors: J Bayarmaa , D Purev 
Published: January 2020

Success in plant cultivation is related to seed production and germination. Seed germination and seedlings are well-regulated process which involves high metabolic activity and production of reactive oxygen species (ROS) in cell. However, plant POS defense network, composed of antioxidant enzymes and antioxidants are responsible for maintaining ROS levels under control. In plant cells, antioxidant enzymes as superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and others protect cells from oxidative damage during germination and growth. Thus, in this work we studied the content of soluble protein and the activity of enzymes as catalase, peroxidase, polythenol oxidase (PPO) and superoxide dismutase in two cultivars of wheat, barley and oat seeds differing in germination and year of harvesting. The results showed that the activities of antioxidant enzymes and seed germination are directly dependent and this relation clearly seen for catalase and peroxidase activity.

Jeg vil have rigtig undervisning! Profiler af blendede learnere i efter- og videreuddannelsen
Authors: Olesen Monica Irene Krarup 
Published: January 2020

Blended Learning er en fleksibel tilrettelæggelsesform, der integrerer forskellige former for asynkron interaktion, hvor de studerende tilegner sig det faglige indhold uafhængigt af fælles tid og rum. Fleksible læringsrum appellerer til voksne studerende i et efter- og videreuddannelsesforløb, hvor der ofte er en række individuelle behov at tage hensyn til som følge af den voksnes familie- og arbejdsliv. I denne artikel præsenteres og diskuteres resultaterne af en undersøgelse , der pågik i efter- og videreuddannelsen på University College Nordjylland i efteråret 2018, hvor 45 diplomstuderende deltog i afprøvning af et blended learning-læringsdesign. Formålet med undersøgelsen var at identificere, hvad der har betydning for voksne diplomstuderende, når de er tilmeldt et uddannelsesforløb tilrettelagt som blended learning. Undersøgelsen har identificeret fire forskellige profiler af blendede learnere i et efter- og videreuddannelsesforløb. De fire profiler afspejler en variation i forhold til deltagernes motivation for både læring og for blended learning. Derudover viser profilerne en stor variation i deltagernes læringstilgang samt de læringsforudsætninger og de læringserfaringer, de bringer med ind i mødet med et blended uddannelsesforløb. Undersøgelsens resultater danner udgangspunkt for videreudvikling af blended learning på diplomuddannelserne med læringsdesign, der sigter mod en højere grad af fleksibilitet og individualiserede læringsrum.

Consumption Pattern and Health Implications of Convenience Foods: A Practical Review
Authors: Dhir Bhavya , Singla Neerja 
Published: January 2020

Background: The present study was aimed to review the consumption pattern and health implications of convenience foods in regular life. The term 'Convenience food' is being widely used in the catering industry due to rapid progress in food technology. Consumption of convenience foods is inexorable in modern scenarios due to rapid urbanization, changing lifestyle, rising purchasing power and adaptation to western culture.
Methods: A constructive review work was done from available data sources and available literatures.
Results: The Indian ‘Ready-to-Eat (RTE)’ market reached at Rs 2900 crore and Rs 3500 crore in 2015 and 2016 respectively. RTE foods are growing at 40% per year. According to the World Health Organization, the trend towards surplus convenience foods provides the food industry with various commercial opportunities and profitable outcome for the food manufacturers. However, these foods are regarded as one of the least healthy dietary options, contributing to the health and diet-related diseases comparable to the risks associated with smoking, alcohol and drugs.
Conclusion: Excessive consumption of convenience foods is one of the major factors for the higher incidence of obesity and other non-communicable diseases.

Published: January 2020

Enteric fever remains a major disease burden in developing countries. Paratyphoid fever has been described as a less severe infection than typhoid fever. Salmonella serovar Paratyphi A has been however seen as an increasing problem in many areas in Asia and can cause a disease with severity proportional to that of Salmonella serovar Typhi.
Among Asian countries China, India, Indonesia, Pakistan, and Vietnam are considered to be endemic for typhoid.
This case describes female infant presenting with long standing lymphadenopathy in the cervical and axillary area. Considering the duration of clinical feature she was investigated for Tuberculosis and Hodgkins lymphoma. The extensive course of investigations ruled out both. Sampling of gastric aspirate in pursuit of diagnosing tuberculosis incidentally revealed Salmonella Paratyphi B repeatedly as the cause of the generalized lymphadenopathy.This is a first report which describes such a case in the best of our knowledge.

Authors: Khater Enas Sh. , Abdo Khalid H. M. 
Published: January 2020

Background: All health care facilities should intensify TB screening and encourage treatment of latent tuberculosis infection (LTBI) among Healthcare workers (HCWs) to prevent progression to tuberculosis (TB) disease.
Aim: This study was conducted to determine the prevalence and associated risk factors of LTBI among HCWs in Al Quwayiyah General hospital as well as to compare the performance of QuantiFERON-TB Gold Plus (QFT-Plus) to TST in identifying LTBI.
Methods: A cross sectional study and prospective cohort study was performed from January to July 2019 in Al Quwayiyah General hospital involving a total of 718 HCWs. questionnaire with socio-demographic data and work history was filled, and both tests were done TST and QFT test for each Healthcare worker.
Results: The study showed that The prevalence of latent tuberculosis diagnosed was 9.05% and 9.19% using QFT-Plus and TST respectively. Only 26 (3.62%) subjects were positive for both tests whereas 131 (18.25%) were positive by either test. Comparing the results of the QFT-Plus with those of the TST, both tests had a significant total agreement of 88.8. Negative concordance comprised 85.37% of the results, and positive concordance comprised 3.62%. However, positive TST but negative QFT-Plus comprised 5.57% of the results, and negative TST but positive QFT-Plus comprised 5.43%. The association between risk factors and QFT-Plus test results in the studied groups showed that the smoking, health status, immunosuppresion, housing, occupation, contact T.B. at work place, past history of TB and diabetes mellitus appear as significant risk factors. The association between the studied risk factors and TST in the studied groups showed sig­nificant difference noted for smoking, BCG vaccination, immunosuppresion, housing, occupation, contact T.B. at work place, past history of TB and diabetes mellitus.
Conclusion: The prevalence of latent tuberculosis diagnosed was 9.05% and 9.19% using QFT-Plus and TST respectively. Testing of HCWs at hire and periodically can help in the detection of LTBI Large scale study is recommended to confirm such findings in Saudi Arabia, also the use of Quantiferon for detection of LTBI beside using TST is recommended as it reduce the false positive reports by TST and is not affected by prior BCG status.
Comparison of environmental, biological and anthropogenic causes of wildlife–vehicle collisions among three large herbivore species
Authors: Saint‐Andrieux Christine , Calenge Clément , Bonenfant Christophe 
Published: January 2020

AbstractWildlife–vehicle collisions are of increasing concern with regards to the continuous and accelerating anthropogenic development. Preventing and mitigating collisions with wildlife will require a better understanding of the environmental and biological drivers of collision risks. Because species of large mammals differ in terms of food requirements, habitat selection and movement behaviors we tested, at the management unit level, if the density of collisions with red deer, roe deer and wild boar differed in terms of spatial distribution and explanatory factors. From 20,275 documented collisions in France between years 1990 and 2006, we found marked differences in the most influential environmental factors accounting for the density of collisions among the three large herbivore species. The effect of road density was higher for the red deer than for the two other species and did not level off at our spatial‐scale of observation. As expected, the annual hunting harvest—interpreted as a proxy of population abundance—was positively associated with the density of collisions for all species, being the strongest for red deer. While the collision density decreased with the proportion of forest in a management unit for wild boar, it increased with the fragmentation of forest for red deer that commute among forest patches between day and night. To reduce the number of wildlife–vehicle collisions, our results suggest to generalize road fencing and/or a control of abundance of large herbivore populations. Mitigation measures should target units where the collision risk is the highest for the most problematic species.
Photo‐Mediated Decarboxylative Ketonization of Atropic Acids with Sulfonyl Hydrazides: Direct Access to β‐Ketosulfones

Published: January 2020

AbstractAn efficient formation of synthetically and biologically relevant β‐ketosulfones via a photo‐mediated decarboxylative ketonization of atropic acids was disclosed. The approach features metal‐free conditions, good functional group compatibility, readily available starting materials and the use of ubiquitous dioxygen as both oxygen source and oxidant. Furthermore, mechanistic studies reveal that the decarboxylative ketonization reaction proceeds via a radical mechanism and may involve a radical chain reaction.magnified image
Influence of oat and spring pea mixtures on forage characteristics in different environments
Authors: Pflueger Nathan P. , Redfearn Daren D. , Volesky Jerry D. , Bolze Ron , Stephenson Mitchell B. 
Published: January 2020

AbstractForage mixtures including oat (Avena sativa L.) and spring pea (Pisum sativum L. spp. sativum) provide opportunities to optimize forage production with increasing forage quality, relative to single species stands. Under different climate scenarios, adjusting seeding rates of these mixtures may produce variable results in forage quantity and quality. We conducted a 2‐yr study at three study sites to evaluate forage characteristics within mixtures of oat and spring pea stands across a semi‐arid to subhumid precipitation gradient. At the western‐most and driest location (219 mm March–June precipitation), the oat monoculture produced 16−19% more total biomass than seeding treatments with mixtures of oat and spring pea. In contrast, at the moderate‐precipitation site (255 mm precipitation), no differences in total biomass were detected for the oat monoculture and seed mixtures of oat and spring pea. Large variation at the wettest site (339 mm precipitation) limited our ability to detect differences for total biomass production across treatments, but weed pressure in Year 2 of the study reduced forage production. Typically, crude protein (CP) concentration decreased linearly (P < .01) as spring pea decreased in the seeding rate, but CP concentration and total CP yield varied for the seeding rate treatments at the different study sites. Environmental condition may influence the benefit of substituting spring pea into a properly managed oat forage crop to increase forage quality. The contribution of spring pea forage in the total forage biomass of mixtures may be limited, especially in drier conditions.
