Negative Effect

Mycotoxins present a significant problem in the diet of pigs. Secondary metabolites of fungi are toxic matter that have a negative effect on health and the performance of animals, as well as on the quality of their products. The creating of mycotosins is a complex process and it is difficult to predict which toxin will be produced and in which concentration. Food is most often contaminated by low concentrations of different mycotoxins (aflatoxins, ochratoxins, trichothecenes, fumonisinsi and zearalenone) which cause a series of undesired effects, depending on the amount that the animal has ingested into the organism. Mycotoxin interactions in the organism are complex, and they can have antagonistic, synergistic or a joint effect, depending on the combination and quantity in which they appear. The pig is a domestic animal which is most sensitive to the effects of mycotoxins. Long-term consumption of feed contaminated with mycotoxins results in a decline in production, a deterioration of the general health and reproductive disorders. One of the most important negative effects in pigs which receive low doses of mycotoxins in the longterm, is immunosuppression. Mycotoxins present very stable links that remain in raw materials and animal products for a long time and thus pose a major health risk for humans. .

Background There have been reports of long-term subjective memory worsening after electroconvulsive therapy (ECT). Aims To study the prevalence and risk factors of long-term subjective memory worsening among patients receiving ECT in routine clinical practice. Method Patients (n = 535, of whom 277 were included in the final analysis) were recruited from eight Swedish hospitals. Participants' subjective memory impairment was assessed before ECT and a median of 73 days after ECT using the memory item from the Comprehensive Psychopathological Rating Scale. Participants also rated their pre-ECT expectations and post-ECT evaluations of the effect of ECT on memory on a 7-point scale. We used ordinal regression to identify variables associated with subjective memory worsening and negative evaluations of the effect of ECT on memory. Results Comparisons of pre- and post-ECT assessments showed that subjective memory worsened in 16.2% of participants, remained unchanged in 52.3% and improved in 31.4%. By contrast, when asked to evaluate the effect of ECT on memory after treatment 54.6% reported a negative effect. Subjective memory worsening was associated with negative expectations before ECT, younger age and shorter duration of follow-up. Conclusions Although subjective memory improved more often than it worsened when assessed before and after ECT, a majority of patients reported that ECT had negative effects on their memory when retrospectively asked how ECT had affected it. This might suggest that some patients attribute pre-existing subjective memory impairment to ECT. Clinicians should be aware that negative expectations are associated with subjective worsening of memory after ECT.

Chronic lymphatic leukemia is second only to acute leukemia in the frequency of infectious complications. In most cases, severe infectious complications are the cause of death in these patients. Modern chemotherapy makes it possible to preserve the ability to work and the life expectancy of patients for a long time. However, the negative effect of cytostatic drugs on the already altered immune system leads to an even greater suppression of immunity and an increase in the number of infectious complications. The search for new ways to combat infections has shown the advisability of long-term outpatient treatment with antibacterial drugs.

The Impact

This article represents the first step in filling a large gap in knowledge concerning why Public Assistance (PA) use recently rose so fast in Japan. Specifically, we try to address this problem not only by performing a Blanchard and Quah decomposition on long-term monthly time series data (1960:04-2006:10), but also by estimating prefecturelevel longitudinal data. Two interesting findings emerge from the time series analysis. The first is that permanent shock imposes a continuously positive impact on the PA rate and is the main driving factor behind the recent increase in welfare use. The second finding is that the impact of temporary shock will last for a long time. The rate of the use of welfare is quite rigid because even if the PA rate rises due to temporary shocks, it takes about 8 or 9 years for it to regain its normal level. On the other hand, estimations of prefecture-level longitudinal data indicate that the Financial Capability Index (FCI) of the local government2 and minimum wage both impose negative effects on the PA rate. We also find that the rapid aging of Japan's population presents a permanent shock in practice, which makes it the most prominent contribution to surging welfare use.

Abstract Small-scale wastewater treatment plants (SWTPs), called Johkasou, are widely used as decentralized and individual wastewater treatment systems in sparsely populated areas in Japan. Even in SWTPs, nutrients should be removed to control eutrophication. An iron electrolysis method is effective to remove phosphorus chemically in SWTPs. However, it is necessary to determine the precise conditions under which phosphorus can be effectively and stably removed in full scale SWTPs for a long period. Therefore, long-term phosphorus removal from SWTPs was investigated and optimum operational conditions for phosphorus removal by iron electrolysis were analyzed in this study. Efficient phosphorus removal can be achieved for a long time by adjusting the amount of iron against the actual population equivalent. The change of the recirculation ratio had no negative effect on overall phosphorus removal. Phosphorus release to the bulk phase was prevented by the accumulated iron, which was supplied by iron electrolysis, resulting in stable phosphorus removal. The effect of environmental load reduction due to phosphorus removal by iron electrolysis was greater than the cost of power consumption for iron electrolysis.

Topical Fluoride

Fluoride, the milestone element of pediatric dentistry, as well as modern dentistry, has been utilized for the last six decades in practice. Researchers all over the world have used fluoride in several forms in the prevention of tooth decay.Today, we are aware that most of this work has involved clinical research with children. It is particularly pertinent that the subject be adequately presented in the field of pediatric dentistry. In 1940's and 1950's were the years of ten-year studies, where caries reductions were first described. The industry of systemic fluoridation, public campaigns and advertisements became popular mostly in western world in 1960's and 1970's. The fluoridated dentifrices and changes of dentrifice formulations were established in 1980's. Many stated that children should receive one form of systemic fluoride and appropriate forms of topical fluoride in 1990's. Analyses showed that maximum protection against caries is obtained when teeth erupt into an environment with low concentrations of ionic fluoride. The similarity in caries reductions obtained in water fluoridation studies and long-term studies with topically administered fluoride regimens, including fluoride-containing dentifrices, indicates that the pre-eruptive effect of fluoride is of borderline significance relative to the more significant post-eruptive effect. It has taken a long time to show that water fluoridation and topical fluoride programs were thus important measures for the control of caries at the community level. Today, we are aware of the fact that the trio of diet, dentifrice and supplementation should exceed the optimal levels.

Long Term Stability

Silica is a well-known impurity in solid oxide fuel cell raw materials, namely NiO and yttria-stabilized zirconia (YSZ). At elevated temperatures silica will migrate to the grain boundaries, form insulating siliceous phases, and lead to a decrease in the ionic conductivity of the electrolyte. Furthermore, silica impurities have been shown to damage the anode/electrolyte interface, such that an overall decrease in cell performance and long-term stability is observed. Despite the fact that silica is ubiquitous in commercial-grade raw materials and can be incorporated from several extrinsic sources, it has negative effects on the solid oxide fuel cell, such that any further contamination should be avoided to prevent performance degradation and eventual cell failure. This paper reviews and outlines the sources and effects of silica on the solid oxide fuel cell, and attempts to determine a guideline for acceptable levels of silica contamination.

Scientific Hypothesis

The rationale for this study is based on the extreme importance of finding a solution to a complex growth dilemma arising from the negative effects of human activity and the limited ability of the ecosystem to regenerate and provide resources required by mankind to ensure sustainable development and the long-term prosperity. The research is aimed at proving a scientific hypothesis that states: when the global raw-materials crisis becomes increasingly noticeable in various countries of the world, including Russia, circular investments may become a driver for long-term economic growth and the launch of far-reaching reforms of the economy in the 21st century. Circular investments in this paper are viewed as a special type of real eco-investment that combines advancements in technology and innovations to ensure renewal and industrial-scale reproduction of resources (raw materials and energy) from industrial and household waste, along with the mitigation and/or elimination of negative effects, on the environment. A multiple linear regression model has been developed to confirm a statistically-relevant connection between circular investments and real GDP. As a methodological foundation for the model, we used the classic Cobb-Douglas production function modified to take into account industrially reproduced raw material resources included in the production process. Further, we have defined major limits for circular investments in Russia today and highlighted the primary measures which are to be taken to launch circular investments in order to find a solution to the complex growth dilemma.

Plastic microbeads pose an environmental problem as they easily enter into waterbodies, take a long time to break down, and their ingestion can have negative effects on aquatic organisms. I found that microbead consumption had a significant negative effect on the growth of northern leopard frog (Lithobates pipiens) tadpoles, as well as their susceptibility to trematode parasite (Echinostoma trivolvis) infection, but minimal effects on leukocyte profiles and infection tolerance. Freshwater snails (Stagnicola elodes) given microbead diets exhibited a non-monotonic response in their production of trematode (Haematolechus parviplexus) infectious stages, with those in the highest microbead treatment tending to exhibit greater growth and shorter longevity. I also found that algae (Chlorella pyrenoidosa) and microbeads created density-dependent aggregations that could be a potential ingestion pathway for herbivorous fauna. Lastly, I found many particles in Ontario wetlands and ponds that may be used for controlled pesticide release, thus potentially posing a threat.

The main direction of state policy regarding the guaranty safety and quality of animal products is the creation of conditions that are safe for human health during the production and sale of food raw materials. According to current legislation of Ukraine responsibility for the safety of food products placed on the manufacturer but government control plays an important role. This is especially true today, when almost 69.5% of meat is produced in private home farms. It is mainly sold in the agro-industrial markets. The State Service of Ukraine for Food Safety should perform the conditions of modern European regulation and base its activities on the basis of risk assessment. One of the risks are parasitosis, as their negative effect affects the health of millions of people in the world. In this cjnnection the purpose of the study was to analyze the dynamics of the identification of invasive diseases at the stages of slaughter of animals and the sale of slaughter products. Research material was reporting on veterinary medicine (Form № 5-vet and Form № 6-vet) of a number of districts of Odessa region for 2014‒2017. It was founded that 75943 animals were slaughtered in 2014‒2017: 91.18% pigs, 8.14% cattle and 0.68% sheep. The analysis of the dynamics of slaughter, depending on its location, showed that from 41.85% to 99.81% of animals were slaughtered at courtyard. According to the results of veterinary-sanitary control and supervision during the slaughter for the studied years there were no cases of diseases. It was founded that 22617 animal’s carcasses came to the agrofood markets of the regions for the years 2014‒2017, among which 89.56% were pig carcasses, 10,11% cattle carcasses and only 0.33% sheep. According to results of veterinary-sanitary examination in the conditions of SLVSE in the markets, specialists established 351 cases of diseases. In the study of pig carcasses 246 cases of diseases were detected: among them of non-communicable (45.93%) and invasive (54.07%) etiology (echinococcosis). Luring the expertise of cattle carcases was founded 96 cases of diseases: – dicroceliosis (98.96%) and exinococcosis (1.04%); during the expertise of sheep’s carcases – 9 cases of diseases – dicroceliosis (66.67%) and exinococcosis (33.33%). Considering that during the reporting period, according to the results of veterinary-sanitary control and supervision during the slaughter of animals, no cases of diseases were detected, but at the same time the number of cases of detection of invasive diseases during veterinary-sanitary examination in SLVSE on markets constantly increases risk management at the stage of slaughter can be considered not sufficiently effective. Also, the results of our research indicate that the current system for managing the safety of slaughter products is still based primarily on the study of the final product. It does not take into account all possible risks at the previous stages of production. This system can’t fully guarantee to consumer safety of products.
