The Impact of Seasonal Changes on Growth Performance, Rumen Fermentation, and Rumen Microbiota Structure of Yaks: An Analysis Using the Supplemented 2.5kg Concentrate Level as an Example

The study investigated the effects of supplementing the same level of concentrate in different seasons on the growth performance, rumen fermentation, serum biochemical index, and rumen microflora changes in yaks, to provide guidance on accurate feeding of yaks in cold and warm seasons. 12 healthy yaks weighing (124.21±15.64) kg were selected for the experiment, with a warm season group from August to October and a Cold season supplemental feeding group from October to December. The results showed that the mean daily gain was significantly higher in the warm season grazing group than in the cold season grazing group (p<0.05). Rumen fermentation, serum biochemical index, and rumen microflora changes also varied significantly between the two groups (p<0.05).

Effectiveness of a Brief Diabetes Risk Assessment Instrument for Detecting Undiagnosed Type 2 Diabetes Among High-Risk Ethnic Communities in West Africa

With the growing burden of type 2 diabetes (T2D) and associated health, social, and economiccosts in sub-Saharan Africa, tools are needed to assess T2D risks rapidly, allowing for targeted early intervention. The objective of this study was to assess the effectiveness of a brief diabetes risk assessment instrument for detecting undiagnosed Type 2 Diabetes among high-risk ethnic communities in Benin, West Africa.

Maximal Distance of Splatters and Droplets Projections Produced by Dental Air and Water-Cooled Instruments Around a Dental Chair in an Open-Plan Area

A dental chair and its environment can be contaminated with droplet/splatter and aerosol particles, which contain various pathogens, including SARS-Cov-2, that can be transmitted by contact or inhalation. We aimed to evaluate the maximal distance of droplet/splatter projections for four different air and water-cooled dental instruments using a patient simulator, to define the boundaries of the open-plan area contaminated immediately after treatment. We used a dental chair unit placed in a room in the open-plan area. Fluorescent powder was added to water, to know the maximal distance reached by the droplet/splatter on the surfaces of the dental room covered with white sheets. Dental care was performed in an artificial mouth using either an air turbine handpiece, a high-speed electric contra-angle, an ultrasonic scaler, or an air/powder polisher with a constant volume of colored water. Maximal distances of droplet/splatter projections were measured after identifying the fluorescent patterns on the surfaces. Calculated heights and angles were then used after normalization to know the maximal distance that could be reached by these projections. In these conditions, the theoretical maximal distance of droplet/splatter projection was 295 cm for the air-powder polisher, followed by 238 cm for the high-speed electric contra-angle, 93 cm for the air turbine and 77 cm for the ultrasonic scaler. Theoretical projections for the ultrasonic scaler did not go beyond the dental room. In our open-plan area, droplet/splatter projections can extend beyond the dental room entrance, but not over 1.80 m-high partitions, and could contaminate areas located nearby. Simple preventive measures would be to limit the perimeter of these projections, for example by installing a door, in addition to measures to limit the scope of aerosols.

Musicians of Wind Instruments and Oral Condition

The wind instruments are the musical instruments most likely to cause oral lesions, because their use involves the involvement of anatomical structures of the oral and perioral cavity. The purpose of this literature review was to assess the impact of wind instruments on the oral condition of musicians. Scientific articles indexed in the databases Pubmed, Lilacs, Scielo, Cochrane and also in Google Scholar were evaluated. Publications from 1935 to 2020 were included and the following descriptors were applied: wind musicians and oral conditions, wind musicians and periodontal conditions, wind musicians and occlusal disorders.

A Review of the Economist’s Approach to Pollution and Its Control

Pollution, being a social and environmental problem, has been a subject of inquiry by environmental economists. Environmental economists see pollution as an externality problem or a market failure, and have therefore investigated factors affecting pollution and its control.

Rumen Methanogens Community as Drivers of Methane Emission

Among the vast and diverse ruminal micro-biota, Archaea account up to 3-4% of the entire microbial population in rumen of ruminants. Methanobrevibacter gottschalkii, Methanobrevibacter thaueri, Methanobrevibacter smithii and Methanosphaera stadtmanae are common ruminal methanogens. Majority of archea are hydrogenotrophic over acetoclastic methanogen in rumen. Methanogens are endowed with co-enzymes that enable them to produce biogenic methane than other microbes. Biogenic methane produced from ruminants has a significant contribution to global warming. So this review enlightened the complete pictures of methanogens in ruminants and their relationships with other ruminal microbes. The study concluded that the methanogen composition remained variable among ruminant species and these dynamics emanated from animal factors, management and geographical variations.

Characterization of Screen-Printed Nickel Oxide Electrodes for p-type Dye-Sensitized Solar Cells

Mesoporous NiO films obtained via screen-printing deposition of a newly formulated paste containing preformed NiO-nanospheres have been employed as nanostructured photocathodes of p-type dye-sensitized solar cells (p-DSCs).

Scanning Electron Microscopic Evaluation of Debris and Smear Layer after Use of Revo-S and CMA Instruments in Straight Root Canals

Biomechanical preparation, disinfection and obturation all together constitute equally important phases of the endodontic treatment. Root canal treatment is based on cleaning, shaping and sealing the root canal system. Its main objectives are the elimination of residual pulp tissue, infected dentine and debris and the reduction of the number of microorganism from root canal system. Many nickel-titanium (NiTi) rotary instruments have been introduced in the last years.

Assessment of Rumen Microbial Adaptation to Garlic Oil, Carvacrol and Thymol Using the Consecutive Batch Culture System

Although plant derivatives have shown promise in reducing enteric methane (CH4) emissions from ruminants in short-term studies, investigation on possible rumen microbial adaptation to these compounds is still limited. The objective of this study was to assess the possibility of mixed rumen microbial adaptation to antimethanogenic plant derivatives over relatively long-term in vitro incubation. Treatments were: garlic oil, carvacrol and thymol, each at a final concentration of 300 mg/l.

Acute Type C Botulism with Fatal Consequences in a Holstein Breeding Establishment in Northern Italy

BOTULISM is a neuro-paralytic intoxication illness caused by the ingestion of neurotoxins of Clostridium botulinum with contaminated water or food. The Gram-positive spore-producing bacterium Cl. botulinum is found worldwide and can survive in spore form for up to 30 years in numerous substrates in the environment. Cl. botulinum is classified into 7 or 8 different types (A, B, C (C1, C2), D, E, F, G) depending on the antigen properties of the botulinum neurotoxins (BoNT) produced, with intoxication mostly appearing in cattle following the ingestion of neurotoxins of type C and D and, less frequently, of type B.
