The Gut Microbiota and Autism Spectrum Disorder
Autism Spectrum Disorders (ASD) are neurodevelopmental illnesses that mostly affect young children; both boys and girls of age of eight years. The disorders results to a substantial influence in the growth of kids in the community. Their symptoms are vividly portrayed through neurological symptoms such as social impairments, stereotyped behavior, and alteration in communication among the patients. However, apart from the neurological symptoms, Autism spectrum disorder is characterized by gastrointestinal (GI) usually signs comorbidities in victims infected with the Autism spectrum disorder although the primary appliances are anonymous. According to Coury and DanielNe, neuroendocrine, neuroimmune, and autonomic nervous systems are the paths used by the gut microbiota to send stimulus on brain development and behavior actions, and this is as a result of the crucial role of the gut microbiota on essential body biological processes such as metabolism and control of body immune homeostasis [162].
The abnormal gut microbiota is capable of leading to the infection of other ailments, for instance, inflammatory bowel infection, as well as the mood disorders. There exists a bond between the gut microbiota and the central nervous system (CNS) over the “microbiome-gut-brain axis” which indicates a straight communication amongst the gut microbiota and the enteric neurons. This is an essential interaction as it has various vital roles in brain functioning, it helps in the secretion of necessary chemicals utilized in brain functioning and also assists in the regulation of the HPA axis. The integrity of the blood-brain is clearly understood to be damaged in patients of autism spectrum disorder. Moreover, the unrestricted dysbiotic microbial cause’s systemic inflammation which in response interferes with the reactivity of the peripheral immune cells to the central nervous system. These biological processes outline the gut microbiota having an active role in autism spectrum disorder pathophysiology.
Gut Microbiota
Human gut comprises of roughly one kilogram of bacteria while the number of the bacteria genes present are unevenly around nine point nine million. Host DNA in comparison with the microbiome DNA is in the ratio of one is to ten. Before the spreading out of the microbiome information, it was believed that the in utero atmosphere was germ-free. Luckily enough the current knowledge has proved that the infant’s gut is prone to infection by the microbiome from various contacts with the mother body skin or fluids. For instance, microbiome from mothers anus, skin, birth canal and the surrounding bacteria that the kid is exposed to in the process of post-delivery phase. Amniotic fluid and the placenta have been proved to be unclean. Thus they can pass on the infection to the neonate. Srikantha, Piranavie, and M. Hasan Mohajeri. Suggests that the microbiome takes possession in the kid’s gut before parturition due to the leading meconium of mice which is unhygienic [21-23].
There are a few number of maternal features that influence the microbiome bacteria transmissions namely; maternal diet and delivery mode however there exist post-delivery aspects which also lead to microbiome bacterial infections, these postnatal factors consist of antibiotics, breast nurturing food and the host heredities that provides configuration of the neonatal microbiome in persons. De, Theije, Caroline GM, maternal high-fat nutrition throughout pregnancy in human neonates reduces the level of Bacteroides while the obesity modifies the gut microbiota thus its influence is related to the autism spectrum disorder in persons [204]. Nurslings acquires the gut microbiota regarding the type of delivery that their mother underwent when giving birth. If the toddler is born through the birth canal, it carries a resemblance to the mom’s vaginal microbiota. Hence there is gut microbiota similar to mum’s skin acquired from a cesarean section. Furthermore, there are some diseases related to dysbiosis of the gut microbiota such as impaired actions, Crohn’s illness, inflammatory bowel infection and also obesity.
The Association between Autism and the Gut Microbiota
Gastrointestinal (GI) warning signs are vividly observed in the autism spectrum disorder patients. The infected children who possess autism spectrum disorder also have shown a few other symptoms including constipation and diarrhoea precisely those kids suffering from Gastrointestinal ailment than those who were safe from autism spectrum disorder. Most of the victims that have gastrointestinal signs sometimes show great interactive expressions such as nervousness, self-injury, and hostility. In recent research, it has been proven that the gut microbiota openly or in a hidden way is related to the autism signs and symptoms through its impact during metabolism and in the immune system.
Strange Intestinal permeability which outcomes in a complex antigenic load from the gastrointestinal region, is present in patients having autism spectrum disorder in a high percentage of about 36.7% in comparison with their family relatives who possess around 21.1% while it is lowered in control children who have about 4.8% of the unusual intestinal permeability. Related cytokines to autism spectrum disorder; interleukin, interferon plus tumour necrosis feature, cross the blood-brain barrier (BBB) and lymphocytes exist in the flow. Kids infected with the gastrointestinal signs possess lower abundances of Prevotella Coprococcus. Moreover, faecal samples from children diseased with autism indicate the availability of high levels Clostridium histolyticum in comparison with the results and findings of the faecal samples taken from unrelated strong, healthy toddlers.
The Immune System Pathways
According to Heijtz and Rochellys Diaz, the brain uses immunological pathways during communication with the gut, recent studies have expressed augmented amounts of pro-inflammatory cytokines in the liquid plasma of the victims. Gut permeability is enhanced by the pathogenic microbiota as well as focal inflammation, resulting to a compromised intestinal barrier that is produced from pressure or contamination, which enables movement of the gut bacteria across the abdominal wall [3047-3049]. This is emptied into the mesenteric lymphoid tissues leading to activation of the immune system via mucosal immune cells, after which it releases inflammatory cytokines, and also initiates a legal system that regulates central nervous system activities. Vagus nerve is triggered by the peripheral cytokines to cause interactive depression while the IgE-mediated allergic insusceptible reply in the intestine lowers the mutual exchange of information and enhances the increase of the verbose mode in the patient. Furthermore, these results are hand in hand with down-regulation of dopaminergic action in the prefrontal cortex and also triggers neuroendocrine coordination in mice.
The Potential Relationship between the Microbiota and Autism Spectrum Disorder
The bidirectional exchange of information between the brain and the gut is passed through the gut-brain axis; research knowledge has shown that the gut-brain axis is applied in the pathogenesis of autism spectrum disorder. Through secretion of macrobiotic toxin, the gut microbiota sends stimuli affecting brain operations using organ systems such as neuroendocrine, autonomic nervous systems, as well as neuroimmune. Gastrointestinal activities are monitored by the mucosa found in the digestive tract as it is composed of a huge number of neurons which are formed of the enteric nervous system. Autistic children compared to the healthy normal kids have shown diversity in the intestinal penetrability where mannitol test was used for testing this factor. The integrity of BBB is promoted by the bacterial products such as acetate and propionate also the germ-free (GF) shows improved BBB permeability.
In conclusion, the abnormal gut is clearly expressed to be in relation with the autism spectrum disorder. Therefore, regarding many updated scientific researches have proved that the treatments that regulates the gut microbiota results to the development in the autism spectrum disorder signs plus the symptoms. Also, gut microbiota is an essential aspect in the control of the gastrointestinal zone operations and the power of susceptible homeostasis. The recurrent occurrence of the gastrointestinal indicators is autistic persons portrays the taking part of the gut microbiota in autism spectrum ailment gastrointestinal pathophysiology. Moreover boosted by the statement on enlarged situations autism spectrum disorder as a result of alteration of the components in the gut microbiota due to “western” practices such as nutrition, prescriptions, and unnecessary general hygiene. Inflammatory circumstances have been associated with an intensification in the Firmicutes proportion like inflammatory bowel diseases (IBD) and obesity. A few cases have indicated sightseen on the significance of the fungal constituent of the gut microbiota in health and infection in the gastrointestinal structure.

Introduction
The term ‘hero’ in arts refers to a character who displays self-sacrifice, courage and nobility in the face of adversity or when dealing with the challenges facing one or more persons in a society. A hero portrays traits such as fortitude, compassion, bravery, nobility and honor. On the other hand, the term ‘anti-hero’ is used to refer to a prominent character who does not have heroic qualities or who displays bad traits (Scott, 2010). In this paper, I explore the similarities and differences in the personal traits, moral characters, achievements and moral decision-making of two renowned artists, namely, Leonardo da Vinci and Salvador Dali.
Comparison between Leonardo and Salvador
Leonardo is widely known as a skilled artist who was born in Italy in 1452 and died in 1519. In addition to being a renowned painter, Leonardo was a writer, botanist, cartographer, geologist, anatomist, inventor, engineer, mathematician, architect and sculptor (Nicholl, 2005). On the other hand, Salvador was a renowned Spanish artist who was born in 1904 and died in 1989. Unlike Leonardo who displayed skills in a variety of fields, Dali specialized in arts. Although Salvador mainly focused on Draftsmanship, he also involved himself in photography, sculpting and making of films (Shanes, 2012).
From my assessment of the two artists, I realized that they had exceptional personality traits. I found that both displayed high level of creativity that enabled them to produce unique work. However, I also found that they displayed several differences in their personalities. Leonardo had passion for art and science, while Salvador had passion for art only (Nicholl, 2005). I found that unlike Leonardo, Salvador used his work to grab the attention of the public. While Salvador had interests in politics, Leonardo did not engage in politics during his life.
I also assessed the achievements of the two artists. One of the achievements of their remarkable is that they managed to produce creative artistic works that earned them fame and honor. Among the most popular works of Leonardo that I came across are The Last Supper, Vitruvian Man and the Mona Lisa. I realized that The Persistence of Memory is the best-known work of Salvador (Shanes, 2012). Unlike Salvador who concentrated on arts, Leonardo made significant contributions to science, as I mentioned earlier. I noted that Leonardo conceptualized concentrated solar power, an armored vehicle, flying machines and adding machines. In addition, he made discoveries in hydrodynamics, optics, civil engineering and anatomy.
With regard to morality, I realized that Leonardo was known for his support for protection of life. He even advocated for the rights of animals. For instance, I he had a habit of purchasing suffering caged rabbits and selling them. However, the available court records show that Leonardo might have been engaging in erotic sexual acts (Nicholl, 2005). The records indicate that Salvador was charged with sodomy together with three other young men in a case that involved a famous male prostitute. Although the case was dismissed due to lack of adequate evidence, some of his works such as Bacchus and John the Baptist manifested eroticism. Just like Leonard, some of Salvador’s paintings and etchings containing erotic features (Shanes, 2012). Despite Leonardo showing support for morality, my overall assessment of the work of the two artists indicates that they did not have moral integrity. Unlike Leonardo who did not openly show support for immorality, Salvador openly supported immoral acts such as the killing Jews by Hitler. His decision to support such acts indicates that he had little or no support for morality.
Conclusion
Leonardo and Salvador did not have explicit qualities of a hero. Despite this, they made significant contributions in supporting the evolution of arts and science. Leonardo made massive contributions in both science and art, while the Salvador made achievements in arts. Although they had similarities and differences in personality traits, achievements, moral traits and moral decisions, their contribution to arts and science is still remarkable today.

Psychology
Psychology can be defined as the study of how people feel, think or act. It is usually determined by different factors which are based on how the mind and behavior of an individual is. Biologically, the thinking capacity of a person may be affected by the environment or any pressure from the outside world, which may totally change the reasoning and decisions that he/she makes.
Every individual in the entire world is currently concerned with gaining intelligence and a better understanding of psychology, so as to help him make better decisions and achieve desirable insights (Koch, 1959). Being knowledgeable about your own mind and feelings makes it better for a person to think psychologically, guard and control his own actions as well as feeling and emotions towards other people. Studying the mind and behavior gives every learner a better chance to relate well with other people and understanding them better.
Types of Psychology
Psychology being a wide field comprises of diverse studies on all aspects of human being which are mainly affected or controlled by the mind. It involves a thorough study on human personalities, understanding, emotion and behaviors which in turn make it to have several areas of application (Miller, 1990). Abnormal psychology takes the first lead of the examples of the study, where it mainly focuses on the evaluation and research on psychopaths and all varieties of mental disorders associated with psychotherapy.
Biological psychology is another kind of study involved in this field, where its facts are closely linked to brain which influences all the behaviors. Such abnormalities may be caused by injuries on brain or other closely associated parts (Koch, 1959). Cognitive psychology takes the third place where its study is mainly based on decision making and all other processes which occur in the brain including memory keeping and attention.
As the study goes on, there is a thorough research on how to cure mental disorders, and this study falls under clinical psychology. This field mainly focuses on how to cure mental disorders by assessing all the possible diagnosis (Hilgard, 1953). The study of how animals behave is called comparative psychology, where the students here are concerned with researching on how human beings differ from animals.
As humans, we are expected to grow, change and have certain abilities towards work. Developmental psychology deals with such study, where morality and all functioning of human beings are weighed under this category (Kalat, 2016). Personality psychology on the other hand studies how human beings are created, and how they reason towards certain issues according to their nature. Social psychology deals with individual’s behavior towards other people, and how the person behaves in public.
Forensic psychology applies its emphasis on maintaining justice, where its study mainly involves research and maintenance of legal structure and protocols (Hilgard, 1953). Organization of employees and all workers needs a well maintained set of brains which run the administration. Industrial-organizational psychology makes it easy for employers to understand their workers and vice versa.
Impacts and Uses Of Psychology
Psychology has played a huge role in several applications in life as the study helps people understand their goals better and how to handle other people. Understanding your mindset and that of other people helps people inform the public well about their own understanding and how they should relate with one another (Kalat, 2016). Performance of workers in a workplace is also improved once such understanding is let in their minds which at the same time help in improvement of personal health and well being.
Child development is one of the most crucial features when upbringing a kid, and this behavior or knowledge is guaranteed by the level of psychological literacy the parent has towards the child (Miller, 1990). Educational programs are mainly developed and guaranteed by psychological knowledge, where the people who educated the people are well equipped with better knowledge of people mindsets and behavior.
