Exercise #4: Gut Microbes

Overeating:
Obesity has been found to have a detrimental impact on your gut microbial life. Person’s who consume large quantities of processed foods can actually impact the life that belongs in their gut. Normally people have a 90% percentage of similar gut microbes (Firmicutes and Bacteroidetes) but with obesity, it has been shown that there are more Firmicutes and fewer Bacteroidetes (John 2016). Overall, the amount of diversity decreases across your whole gut microbial life. The over processed foods do not give the proper nutrition in the small intestine to sustain different types of bacteria, which results in their death. This can be very bad for microbe-specific activities in your gut, the major one being the metabolic pathway. This can lead to slow metabolic pathways, which doesn’t allow for people to correctly and efficiently process the foods that they eat.

Not eating enough:
People who do not get enough food or nutrition in their diets (whether by choice or not) have a large impact on their gut microbes. Without necessary nutrition, these bacteria are unable to reach full maturity (Monira, 2011). This is very bad for your health. If your microbes are not fully mature, that leads to not fully functioning cells. The microbes are unable to fully break down foods in your body and decrease your likeness of gaining weight by nutrient absorption. This leads to fatigue and an even further puts the person in the situation to be malnourished.

Increase in exercise:
An increase in exercise leads to enhanced microbial diversity in your gut and has been shown to also increase butyrate-producing microbes (Haridy, 2017). Butyrate microbes have been linked to a healthy colon conditions. This has a very beneficial effect on human health. A good colon has been shown to decrease dehydration and speed up bowel elimination.

Lack of sleep:
Not getting enough sleep can have a very negative effect on your gut microbes and overall health. Lack of sleep has been shown to change your circadian rhythms (the normal sleep cycles), which doesn’t allow the gut microbes to sufficiently decay and renew the microbial life. Renewal and decay doesn’t only occur during your sleep cycles but part of it has been linked to doing so (Breus, 2016).Without sufficient sleep, your gut microbes can’t perform their normal functions such as lower levels of cortisol, produce serotonin, and produce probiotics (which increases levels of tryptophan)(Morea, 2017).

Exercise #3 HPV and Prevention

After reading this article, I would recommend that they focus on making a new treatment that also covered the strains 31 and 45. Since there is a vaccination already available for HPV 16 and 18, it would only make sense to also make treatments for types 31 and 45 since together they all (strains 16, 18, 31, and 45) make up nearly 80% of all cervical cases. In a perfect world, it would be amazing to have the ability to vaccinate against all strains but I would definitely recommend making treatments for the strains that are most frequently seen. Hopefully making a treatment for these two strains would be less complicated than a strain that isn’t well documented or frequent. As far as when the recommended dosage should be given to the public, it would need to be before a person becomes sexually active. HPV is contracted through sexual contact with the genital areas. It is really important that both girls and boys are given vaccinations before they reach that point in maturity. I would recommend given the treatments to young teens roughly in middle school years (roughly 11-14). It might seem young but culturally teens are shown to be sexually experimenting at younger and younger ages.

Exercise #2

In the primary research paper “Symbiotic gut microbes modulate human metabolic phenotypes” (2007), Min Li et al used a multivariate strategy to show the covariation between gut microbiomic structural patterns as using NMR spectroscopic urinary profiling to connect metabloic phenotypes and structure of gut microbiome and patterns in host physiology or pathology. Min Li et al found produced evidence of variation between Subdoligranulum variable BI-114 which produces 4-cresol that links variation between different gut bacteria and metabolites found in urine. The purpose of this paper was to identify another method of testing to be done on human hosts to connect differences in gut bacteria to specific pathologies or phenotypes. The intended audience is aimed at persons who are in the medical field or researchers who are interested in pathologies involved with gut bacteria.
