Background:
In the last decade, the harmful use of dioxin has been demonstrated in human
health and in the whole environment. It is well known among scientists that 2, 3, 7, 8-tetrachloro
dibenzo-p-dioxin (TCDD) is an environmental pollutant that causes endocrine disruption, which causes
male reproductive toxicity.

Objective:
The objective of the present study was to evaluate the toxicity effect of low doses of TCDD
in male CD1 mice.

Materials and Methods:
Three concentrations of TCDD (0.375, 0.75, 1.5 mg / kg) were analyzed and
the effects on spermatozoa were evaluated 10 days after oral administration of the product. As
bioindicators of TCDD toxicity, an exhaustive analysis of several spermatic parameters including
motility, vitality, count, morphology and viability, flow cytometry was used to determine the affected
sperm population by cytotoxicity and apoptosis. In addition, a morphometric analysis of testicles was
performed.

Results:
The results show that the body weight of the treated animals was reduced in medium and high
doses (0.75, 1.5 mg / kg) with respect to the control groups. In the groups treated with TCDD, the
abnormal head of the sperm increased by 52.5% more than the control group. Significant differences in
apoptosis were observed between the negative control and vehicle control, including the median dose
(0.75 mg / kg).

Conclusion:
It is concluded that at these low doses there was an impact on the quality of the mouse
sperm, adding an effect on apoptosis and cytotoxicity of sperm exposed to these doses of TCDD.

AbstractWe study the dc magnetization of a Bi_1.94Fe_0.06Se_3 single crystal in the temperature range of 1.9 to 400 K in applied magnetic fields up to 70 kOe for two sample orientations in the applied field. We register three magnetic phase transitions and observe considerable anisotropy of the magnetic properties. The coercive force varies with temperature in a nonmonotonic manner. For the sample in a paramagnetic state, we estimate its magnetic moment per iron atom; its Curie–Weiss temperature is found to be negative. Arrot–Belov plots are constructed.

AbstractInfluence of small additives of fullerene, graphene oxide, and their combinations in the ratio of 85 : 15 on the structure and mechanical properties of cross-linked polyurethanes under static and dynamic loads has been investigated. Nanocomposite structures have been studied by X-ray diffraction analysis and scanning electron microscopy. It is shown that the presence of carbon nanoparticles in the composite reduces its strength under both static and shock-wave loads. The synergistic effect of the mixture of carbon nanoparticles manifests itself as an increase in the elastic modulus by a factor of 1.25 in comparison with the initial polymer.
If You Tweet, They Will Follow: CEO Tweets, Social Capital, and Investor Say-on-Pay Judgments
Authors: Kelton Andrea Seaton , Pennington Robin R. 
Published: May 2019

ABSTRACT
Chief executive officers (CEOs) are increasingly using social media to disclose information and communicate with investors. Although findings from archival research show some benefits to social media use, little is known about how the social nature of this disclosure channel affects individual investors. Accordingly, we develop a mediation model based on social capital theory that predicts social media disclosure channels lead investors to perceive enhanced feelings of connectedness (i.e., social capital) with the CEO, resulting in more positive judgments of the CEO. Specifically, our model predicts CEO disclosures via Twitter, versus web-based disclosures, lead to enhanced perceptions of social capital, which in turn positively impact investor recommendations for CEO compensation. Using an experiment with individual investors, our results provide robust support for our theoretical mediation model. Our findings enhance our understanding of how CEOs' social media use influences individual investors and have implications for standard setters, investors, and firms.

IntroductionExcessive alcohol consumption has adverse effects on health and there is a recognised need for thelongitudinal analysis of population data to improve our understanding of the patterns of alcohol use,harms to consumers and those in their immediate environment. The UK has a number of linkable,longitudinal databases that if assembled properly could support valuable research on this topic.
Aims and objectivesThis paper describes the development of a broad set of cross-linked cohorts, e-cohorts, surveys andlinked electronic healthcare records (EHRs) to construct an alcohol-specific analytical platform inthe United Kingdom using datasets on the population of Wales.
The objective of this paper is to provide a description of existing key datasets integrated withexisting, routinely collected electronic health data on a secure platform, and relevant derived variablesto enable population-based research on alcohol-related harm in Wales. We illustrate our use of thesedata with some exemplar research questions that are currently under investigation.
MethodsRecord-linkage of routine and observational datasets. Routine data includes hospital admissions,general practice, and cohorts specific to children. Two observational studies were included. Routinesocioeconomic descriptors and mortality data were also linked.
ConclusionWe described a record-linked, population-based research protocol for alcohol related harm on a secureplatform. As the datasets used here are available in many countries, ELAStiC provides a templatefor setting up similar initiatives in other countries. We have also defined a number of alcohol specificvariables using routinely-collected available data that can be used in other epidemiological studiesinto alcohol related outcomes. With over 10 years of longitudinal data, it will help to understandalcohol-related disease and health trajectories across the lifespan.
