Hydrargyrum (familiar as mercury) is a persistent transition metal element. They are known as bio-accumulative properties that are dangerous to the environment and has serious damaging effects on biota, including genetic changes or mutagenesis. Moreover, it can accumulate indirectly in the human body due to the consumption of products that have contaminated. Whereas, ellagic acid has reported as one of 13 flavonoid compounds that have potential as an anti-mutagen and anti-cancer in the walnuts seeds. This study was aimed to ensure the potential extent of ellagic acid extracts in walnut seeds to reducing and repairing the genotoxicity effects of mercury. Therefore, using the experimental method, this study was divided into several test treatments. Two controls treatment as a comparison of the presence of micronucleus with group tests that given a 20 ppm mercury dosage. Then continued with the addition of walnut seed extract with various dosage (10, 15, and 20 ppm) by oral injection continuously for two weeks as a recovery process to reducing and repairing the genotoxicity effect of mercury. The significant results showed that there are differences between pre and post-treatment. It indicated that the extract has the potential for improving and reducing the genotoxicity effect of mercury. The data were evaluated and obtained the total micronucleus from the smear of peripheral blood of mice by comparing the total micronucleus before and after giving of walnut extract.

This study illustrated the physiological and psychological effects of watching videos of different durations showing bamboo forests with varied structures. Physiological indicators, including EEG (electroencephalogram), blood pressure, skin conductance, and pulse, were monitored in 180 Chinese university students (mean age: 20.72 ± 2.56 years) while they were watching bamboo videos. Before and after watching the videos, their psychological indicators, including positive and negative moods, were measured using the Profile of Mood States questionnaire. After watching the bamboo videos of different durations, all of the physiological indicators responded to the stimulation after only 1 min. The indicators showed different trends at 1, 3 and 5 min. EEG decreased and then was maintained at a stable level after 1 min, and the high β, low β, and α waves had no significant differences between 1, 3 and 5 min. Blood pressure dropped to a stable state after 3 min, and the decline was significantly different greater after 3 min than after 1 min. Skin conductance increased for 1 to 5 min, and it did not stabilize after a long time (5 min). Pulse decreased after 1 min but increased after 5 min. After watching the videos with bamboo of varying structures, the physiological and psychological indicators showed significantly different changes. Skin conductance significantly increased (mean value: 6.78%), and the amount of sweat was more effectively reduced, thereby reducing tension, when the students viewed videos of sympodial bamboo forests compared with monopodial bamboo forests. Bamboo forests with a higher canopy density (0.83–0.85) could significantly decrease α waves (mean value: 1.50 Hz), relaxing the human body. High β and low β waves showed greater decreases, with tension reduced more effectively, when bamboo forests with a low tilt ratio (< 1.5%) were viewed. Bamboo forests with neat undergrowth could have more beneficial physiological and psychological effects on the human body.

Human Body Composition

The purpose of this study was to compare the estimates of lean body mass (LBM) and percent body fat (%BF), as predicted by bioelectrical impedance (BIA) and sum of skinfolds (SF), with those derived by hydrostatic weighing (HW) obtained before and after a 10-wk diet and exercise regimen. The experimental (E) group consisted of 17 healthy male subjects; 20 healthy males served as the control (C) group. Post hoc Scheffe contrasts computed on E group data indicated that, for both LBM and %BF, the Lukaski and Segal BIA equations, as well as the Durnin SF equation, derived mean values that were not significantly different (0.05 significance level) from HW in both pre- and postregimen conditions. For LBM, the same equations derived the following significant (P less than 0.01) correlation coefficients for both pre- and postregimen data: Lukaski, 0.87 and 0.85; Segal, 0.89 and 0.87; and Durnin, 0.90 and 0.88. For %BF, the correlation coefficients were slightly lower but remained statistically significant (P less than 0.01). The findings of this study suggest that the BIA method, by use of either the Lukaski or Segal prediction equations, is a valid means of predicting changes in human body composition as measured by the Siri transformation of body density.

Abstract Objectives Breast cancer is a common malignant tumor in women with limited treatment options and multiple side effects. Today, the anti-cancer properties of natural compounds have attracted widespread attention from researchers worldwide. Methods In this study, we treated 4T1 tumor-bearing Balb/c mice with intraperitoneal injection of Auraptene, paraffin oil, and saline as two control groups. Body weight and tumor volume were measured before and after treatment. Hematoxylin and eosin (H & E) staining and immunohistochemistry of Ki-67 were used as markers of proliferation. In addition, ELISA assays were performed to assess serum IFN-γ and IL-4 levels. Results There was no significant change in body weight in all animal groups before and after treatment. 10 days after the last treatment, Auraptene showed its anti-cancer effect, which was confirmed by the smaller tumor volume and H & E staining. In addition, Ki-67 expression levels were significantly reduced in tumor samples from the Auraptene-treated group compared to the paraffin oil and saline-treated groups. In addition, in tumor-bearing and normal mice receiving Auraptene treatment, IL-4 serum production levels were reduced, while serum levels of IFN-γ were significantly up-regulated in tumor-bearing mice after Auraptene treatment. Conclusions In the case of inhibition of tumor volume and Ki-67 proliferation markers, Auraptene can effectively inhibit tumor growth in breast cancer animal models. In addition, it might increases Th1 and CD8 + T cell responses after reducing IL-4 serum levels and IFN-γ upregulation, respectively. However, further research is needed to clarify its mechanism of action.

Role Playing Game

&lt;p&gt;The increased complexity of disaster risk due to climate change, expected population growth and the increasing interconnectedness of disaster impacts across communities and economic sectors, require Disaster Risk Reduction (DRR) measures and practitioners that are better able to address these complexities. Nonetheless, in the traditional risk paradigm, there is a strong focus on single-hazards and the risk faced by individual communities and sectors.&lt;/p&gt;&lt;p&gt;&lt;em&gt;Breaking the Silos&lt;/em&gt; is a narrator-led, role-playing game designed to support decision makers and stakeholders in understanding and managing the complexities of implementing DRR measures in a multi-(hazard) risk setting.&amp;#160;The game starts in de aftermath of a (randomly selected) disaster. The different roles include key decision-makers and stakeholders of a country. The team is responsible for the post-disaster recovery process and can decide to implement DRR measures. However, while some of these DRR measures can decrease risk of one hazard, they can increase the risk of another hazard. In each subsequent round, the team faces another (randomly selected) disaster. Unlike many other risk serious games, &lt;em&gt;Breaking the Silos &lt;/em&gt;includes many random factors to better simulate reality. The roles are designed such that expert knowledge and objectives are spread throughout the participants and they can even be conflicting at times.&lt;/p&gt;&lt;p&gt;The game was successfully launched during the World Bank&amp;#8217;s 2020 Understanding Risk conference. Before and after playing the game, participants were asked to complete surveys asking them about their perception of the challenges of Disaster Risk Management and whether the game raised their awareness of these challenges. The preliminary findings indicate that &lt;em&gt;Breaking the Silos&lt;/em&gt; is a useful tool in supporting decision makers and practitioners to become aware of (the risks of) hazard-silo thinking and possible (a)synergies of DRR measures.&lt;/p&gt;

To Receive

43 Background: Most oral anti-cancer drugs (OACD) prescriptions require extensive coordination between providers and payers, which can delay drug receipt. Specialty pharmacies are intended to facilitate communication between multiple entities to deliver OACDs with increased efficiency. In 2018, our cancer center partnered with Shields Health Solutions (SHS), a freestanding organization providing care coordination to implement a hospital-based specialty pharmacy. We evaluated the rate of failed drug receipt (FR) and time to drug receipt (TTR) before and after specialty pharmacy implementation. Methods: We prospectively collected data on all new OACD prescriptions for adult oncology patients at a large, urban cancer center from 1/1/2018 to 12/31/2019. In fall 2018, a specialty pharmacy was opened to facilitate drug procurement for patients. We collected patient demographic, clinical, and insurance data, OACD name, date prescribed, delivery date, and interactions with payers and financial assistance groups. For prescriptions received, TTR was the number of days from OACD prescription to patient receipt of the drug. FR was defined as failure to receive a prescribed OACD. We excluded OACD prescriptions for a washout period of two months during pharmacy initiation. We used multivariable logistic regression to examine factors associated with TTR > 7 days and FR before and after specialty pharmacy implementation. Results: In total, 883 patients were prescribed 1145 new OACDs. The majority of prescribed drugs were targeted treatment (56%, N = 646) and 72% (N = 819) required prior authorization (PA). Of all prescriptions, 86% (N = 999) were successfully received with an overall median TTR of 7 days. Adjusted analyses showed that patients were more likely to receive their drugs in less than 7 days after specialty pharmacy implementation (OR: 1.4 95% CI 1.04 – 1.81), p = 0.03). In an unadjusted analysis, patients were more likely to receive their initial medications after specialty pharmacy implementation, compared to before specialty pharmacy implementation (89% vs. 84%, p = 0.04). Multivariable analysis showed a trend toward more patients receiving drugs after specialty pharmacy implementation (OR: 1.42, 95% CI 0.98 – 2.03, p = 0.06). Conclusions: The implementation of a hospital-based specialty pharmacy in partnership with SHS decreased TTR. This difference is in part attributable to improved care coordination and communication. A centralized approach may improve overall efficiency due to fewer clinical practice disruptions.

Key Issues

The pore structure and gas adsorption are two key issues that affect the coal bed methane recovery process significantly. To change pore structure and gas adsorption, 5 coals with different ranks were treated by CS2 for 3 h using a Soxhlet extractor under ultrasonic oscillation conditions; the evolutions of pore structure and methane adsorption were examined using a high-pressure mercury intrusion porosimeter (MIP) with an AutoPore IV 9310 series mercury instrument. The results show that the cumulative pore volume and specific surface area (SSA) were increased after CS2 treatment, and the incremental micropore volume and SSA were increased and decreased before and after Ro,max=1.3%, respectively; the incremental big pore (greater than 10 nm in diameter) volumes were increased and SSA was decreased for all coals, and pore connectivity was improved. Methane adsorption capacity on coal before and after Ro,max=1.3% also was increased and decreased, respectively. There is a positive correlation between the changes in the micropore SSA and the Langmuir volume. It confirms that the changes in pore structure and methane adsorption capacity due to CS2 treatment are controlled by the rank, and the change in methane adsorption is impacted by the change of micropore SSA and suggests that the changes in pore structure are better for gas migration; the alteration in methane adsorption capacity is worse and better for methane recovery before and after Ro,max=1.3%. A conceptual mechanism of pore structure is proposed to explain methane adsorption capacity on CS2 treated coal around the Ro,max=1.3%.

Abstract Background: The aim of this paper is to compare the patterns and determinants of cancer mortality in Najran region before and after the COVID-19 epidemics. The association between cancer mortality and each of age, sex, site of cancer, stage, and the 30-days survival rate after the last dose of chemotherapy were assessed.Materials & Methods: Adult cancer patients who died of cancer in King Khalid Hospital in Najran Saudi Arabia, were included in this retrospective observational study. We compared mortality patterns in a period of 6 months in 2020 (March to August) with the corresponding period of 2019.Results: 50 dead adult cancer patients were included, 24 in 2019 and 26 in 2020. Among them, 21% vs 42% were younger than 65 years of age; 61% vs 62% were males, for the years 2019 & 2020 respectively. The top three killers in 2019 were colorectal, gastro-esophageal cancers, and hepatocellular carcinoma, while in 2020 were colorectal, hepatocellular carcinoma, and lymphomas. About 16.7% of patients died within 30 days of receiving anti-cancer treatment in 2019 in comparison with 7.7% in 2020. The difference in the 30-days mortality after receiving anti-cancer treatment was not statistically significant between 2019 and 2020 (p = 0.329).Conclusion: The Year 2020, the time of the COVID-19pandemic, was not associated with a significant increase in short-term mortality among patients with malignancy in Najran, Saudi Arabia. Our results generally reflect the crucial role of strict preventive national measures in saving lives and warrants further exploration.
