Dentists treat a wide range of patients, including patients with compromised health conditions. While rendering treatment, various medical emergencies can and do occur. To help increase the knowledge required to manage such emergencies, dental students must be trained while in dental school. This study aims to assess the level of medical emergency preparedness and knowledge among dental students at four dental schools.
The participating dental schools were IUSD, Case Western Reserve University School of Dentistry, Marquette University School of Dentistry, and the University of Alabama School of Dentistry. Groups were designed to include 20 dental students from Years 1 to 4. Students were asked to fill out a survey and were then tested on 10 clinical medical emergency scenarios.
A total of 331 dental students participated in the study. The scores based on 10 case scenarios presented with a range of 4.35-8.02. There was no statistically significant difference in the level of preparedness when dental schools were compared. However, Year 1 and Year 2 dental students had significantly lower total scores than those of Years 3 and 4. The students in Years 1 and 2 demonstrated less confidence in their current knowledge to manage medical emergencies. Satisfaction with the training received ranged from 38% to 84%.
The results from this study indicate that students' preparedness to manage medical emergencies at these four dental schools is statistically similar. Additional yearly training could enhance students' preparedness in the management of medical emergencies in the dental setting.

However, the class of all responses consists of 2 sub-classes which are discriminable by their properties Reinforced responses always equal obtained reinforcers, while unreinforced responses are free to vary. As a result, the inclusion of reinforced responses in choice measures results in sensitivity values in generalized matching that are biased toward larger values, and this bias becomes extreme in some combinations of overall response and reinforcer rates. Different ways of varying concurrent-schedule values also affect estimated sensitivity and the linearity between choice based on all responses and reinforcer ratios. To avoid spurious results and comparisons, and as a matter of good practice, generalized-matching fits and measures should be done using only unreinforced responses.
The separation and purification of Porphyra haitanensis polysaccharide (PHP), and the determination of changes in molecular weight (Mw) and antioxidant capacity after in vitro digestion, were undertaken.
Analysis of two polysaccharide fractions (PHP0.5-1-UF and PHP1.0-1-UF) by various techniques showed that they were very pure sulfated polysaccharides without pigment or protein. PHP0.5-1-UF was filamentous or 'tape-like' sheets, whereas PHP1.0-1-UF had some filaments and large numbers of rounded aggregates. The Mw of PHP, PHP0.5-1-UF and PHP1.0-1-UF was 2.06 × 10
(±2.02%), 6.68 × 10
(±3.17%), and 1.14 × 10
(±3.44%) (g mol
), respectively. After in vitro digestion, the Mw of PHP, PHP0.5-1-UF, and PHP1.0-1-UF decreased. Their antioxidant capacities were markedly higher than before digestion, especially PHP0.5-1-UF and its digestion products, which might be related to the reductions in Mw.
These findings provide a greater understanding of the separation and purification of sulfated polysaccharides and the influence of digestion on biological activity. They also contribute to the practical application of sulfated polysaccharides in functional foods. © 2021 Society of Chemical Industry.

Germination of mung beans increases the content of dietary fiber, vitamin C, antioxidants, and γ-aminobutyric acid (GABA). Atmospheric cold plasma is a recently developed technology that can rapidly modify the surface properties of an object. In this work, atmospheric cold plasma was utilized to promote higher moisture absorption of mung bean seeds and, thus, enhance the germination ratio and GABA level. The selected healthy seeds that were exposed to plasma generated at different ionizing powers.
According to the experimental results, atmospheric cold plasma treatments on mung bean seeds could induce significantly more water absorption and lead to a higher rate of germination. The physical appearance of the sprout developed after plasma treatment was noticeably modified to a more desirable form, which has a short radicle and longer hypocotyls with a larger diameter. The content of the bioactive component GABA in plasma-treated beans was approximately three times higher than the untreated group due to the response of seed to the environmental stress created by the plasma treatment.

To assess long term survival and patient characteristics associated with survival following acute myocardial infarction (AMI) in Australia and New Zealand.
Cohort study.
All patients admitted with AMI (ICD-10-AM codes I21.0-I21.4) to all public and most private hospitals in Australia and New Zealand during 2009-2015.
All-cause mortality up to seven years after an AMI.
239402 initial admissions with AMI were identified; the mean age of the patients was 69.3 years (SD, 14.3 years), 154287 were men (64.5%), and 64335 had ST-elevation myocardial infarction (STEMI; 26.9%). 7-year survival after AMI was 62.3% (STEMI, 70.8%; non-ST-elevation myocardial infarction [NSTEMI], 59.2%); survival exceeded 85% for people under 65 years of age, but was 17.4% for those aged 85 years or more. 120155 patients (50.2%) underwent revascularisation (STEMI, 72.2%; NSTEMI, 42.1%); 7-year survival exceeded 80% for patients in each group who underwent revascularisation, and was lower than 45% for those who did not. Being older (85 years or older v 18-54 years adjusted hazard ratio [aHR], 10.
