Obesity, heart disease and Diabetes are fast  becoming major public health concerns. In America approximately 30.3 million people have diabetes, that’s almost 10% of the population. Diabetes type 2 is a long term disease that can have serious consequences. Around 2/3rds of Type 2 Diabetes sufferers die prematurely due to a stroke or heart disease. A study by the European Journal of Clinical Investigation shows that regular exercise helps to fight diabetes and other inflammatory diseases.

Regular exercise helps to produce inflammation-fighting Cytokines

The study aimed to “provide the reader with an update of the mechanisms whereby exercise-induced cytokines may impact cardiometabolic diseases.” by reviewing the data from previous investigations. The results show that regular exercise provided significant natural anti-inflammatory properties. This is thanks to the cytokines that exercise produces.
Cytokines are cell signaling modules that help to coordinate immune responses and direct cells to areas of inflammation or trauma. Think of them as tiny wifi-hotspots, letting cells better communicate with each other.  They are important to our immune responses and some Cytokines help to regulate the body’s response to inflammation.
Professor Klarlund Pedersen found that even moderate elevations of IL-6 and IL-10 have a direct anti-inflammatory effect. IL-6 can help to inhibit the effects of diabetes by allowing the body to better regulate the production of insulin. A lack of IL-6 contributes insulin resistance. In other words a lack of IL-6 is a major factor in an individual becoming diabetic.
The study further found that 30 minutes of heavy exercise  can increase concentrations of IL-6 by up to five-fold with an “almost exponential” effect the longer you continue exercising. In other words, the longer you run the more benefits you receive. The study also noted that this effect only applies to exercises that involve large numbers of muscle groups, such as running or swimming. This effect drops off quite rapidly once you stop working out, so only regular exercise helps to fight diabetes and other diseases.

The evidence is mounting that exercise may be key in helping to fight many different diseases

The European Journal of Clinical investigation study is in line with previous studies which point to the benefits of exercise in helping to fight a number of cancers and having an important role in preventing many different diseases in the first place. The consensus that regular exercise helps to fight diabetes and many other diseases is growing.
They also demonstrated that a lack of physical activity actually contributes to the risks factors that can contribute to somebody getting heart disease or diabetes. Even 14 days of inactivity led to a huge increase in abdominal fat, a major factor to the symptoms of type 2 diabetes.

Regular exercise will be key in treating a range of chronic illnesses

The report concludes that the benefits of exercise are well documented and apparent for all to see. They recommend that a regular exercise program be considered as part of the regular course of treatment for all diabetes sufferers. This is a recommendation that will likely be applied to other diseases in due course. That said, exercise is not a cure all and it should not be used in place of medicine prescribed by your doctor but rather as a supplement to any ongoing treatment.
Given the power of exercise to help fight and prevent so many disease I think that I might have to start taking my trips to the gym a little more seriously. Maybe.

Why is there a distinction between an Innie and an Outie belly button?

We are interested in addressing some of the most urgent inquiries that society has regarding science. Is it necessary to include death education in schools? What is the impact of ultra-processed foods on human health? Today’s agenda includes a crucial question: what is the reason for an “innie” or an “outie” belly button?

What constitutes a globus dorsi?
Prior to delving into the intricacies of innies and outies, it is imperative to establish a comprehensive understanding of the concept of a belly button. The umbilicus is the scientific term for the belly button, serving as a convenient reminder that it is the location where the umbilical cord, which connects a developing fetus to the placenta, used to be.

Following childbirth, the umbilical cord becomes unnecessary and is commonly severed and secured, resulting in a small stump that gradually desiccates and detaches. The scar that remains following this procedure is commonly referred to as the belly button.

The process of in-and-out formation
There exists a belief among certain individuals that the presence of an innie or an outie belly button is contingent upon the manner in which the umbilical cord is severed or the location of the clamp. However, this assertion is unfounded. The outcome ultimately hinges on the individual’s healing process and the formation of the scar. Nevertheless, certain medical diseases, such as umbilical hernias and granulomas, may be erroneously identified as an external abdominal protuberance.

There is no need for concern over a typical outie belly button, although it is worth noting that this particular variety is relatively uncommon. 90% of people have an innie belly button, while the remaining 10% have an outie. Within the innie and outie categories, there are numerous subtypes that differ from one another in terms of things like form, orientation, and depth.

If you are the proud owner of an innie, while you are (ideally) removing any excess material that may have accumulated (which is a common occurrence), you may also unintentionally uncover a substantial amount of bacteria. In a 2012 scientific investigation, researchers collected samples from individuals’ navels and identified more than 2,300 distinct bacterial species within a mere 60 abdominal buttons. Some individuals have even employed belly button microorganisms for the production of cheese.

Belly buttons have the potential to undergo alterations on occasion.
While the majority of individuals do not experience any changes in their belly button, there are certain factors that can contribute to alterations in the look of some individuals’ navels. The initial procedure is referred to as umbilicoplasty, a cosmetic surgical intervention aimed at altering the dimensions and/or configuration of the rectum.

Another factor to consider is the presence of medical disorders that exert additional pressure on the region, resulting in the protrusion of a typically small belly button. The most prevalent of these circumstances is pregnancy, in which the developing baby exerts the force on an innie to expose itself. This phenomenon can result in the premature rupture of an innie at approximately 26 weeks of gestation, although it typically reverts to its typical introverted state upon the conclusion of the pregnancy.

The presence of any type of abdominal button is considered to be within the normal range. Please be certain that you thoroughly clean all the crevices, for the sake of everything that is virtuous.

Is every face seen as demonic by you? Then you may possess a very uncommon condition

It is often assumed that our view of others’ faces accurately reflects their true appearance. However, a minority of individuals with a rare neurological disease have skewed perceptions. Researchers have successfully visualized the visual perception of individuals with prosopometamorphopsia (PMO), a disorder characterized by the inability to recognize faces.

The illness known as PMO is considered to be quite uncommon, with just around 75 documented case reports available. Consequently, its understanding remains limited. Nevertheless, individuals with this disorder are aware that they see facial characteristics as distorted. However, the specific manifestations of these distortions, such as variations in form, size, and location of features, might differ across individuals.

According to Antônio Mello, the principal author, it might be challenging to accurately envision the perspectives of individuals in a project management office (PMO). “In previous research on the condition, individuals with PMO struggle to accurately evaluate the representation of their distortions in a visualization due to the presence of a face in the visualization, which leads patients to perceive distortions on it as well.”

However, the researchers at Dartmouth College encountered an exceptional instance involving a 58-year-old guy who only saw faces as distorted when seen in person but perceived them properly when presented with a photograph shown on a screen or paper.

Due to the patient’s ability to see both distorted and authentic faces, it provided the researchers with a chance to precisely depict his visual perception. In order to do this, a photograph of an individual’s visage was captured and then shown to the patient on a computer screen while the actual person was there, with the patient being instructed to compare the disparities in real-time.

By enabling the team to modify the picture shown on the screen to align with the distortions seen by the patient in the real face, it becomes evident why he has been referring to people’s looks as “demonic.”.

The researchers want their results to enhance doctors’ awareness of PMO and provide a deeper comprehension of their patients’ experiences. Consequently, this might aid in diminishing instances of underdiagnosis or misdiagnosis. It is sometimes misconstrued as a mental condition rather than a neurological one. In this patient’s case, he might have seen people who resembled demons, but there was no delusional belief that they were actually demons.

“Several individuals with PMO have reported being diagnosed with schizophrenia by psychiatrists and prescribed anti-psychotic medications, despite their condition actually being related to visual impairment,” said senior author Brad Duchaine.

“It is not unusual for individuals with PMO to withhold information about their issue with face perception due to concerns that others may interpret the distortions as indicative of a psychiatric condition,” said Duchaine. The issue at hand is often not comprehended by others.

The research has been published in The Lancet.

Weight Loss Launchpad: Space Technology Enhances the Effectiveness of Obesity mRNA Treatment

Researchers at Penn Engineering have devised an innovative approach for the synthesis of a vital component of lipid nanoparticles (LNPs), drawing inspiration from space shuttle technology. LNPs play a crucial role in the administration of mRNA therapeutics, as exemplified by the Pfizer-BioNTech and Moderna COVID-19 vaccines. They enhance the ease of LNP manufacturing and enhance their efficacy in facilitating the transportation of mRNA into cells for medical interventions.

In an article published in Nature Communications, Michael J. Mitchell, an Associate Professor in the Department of Bioengineering, presents a novel approach for the synthesis of ionizable lipidoids. These lipidoids are crucial chemical constituents of lipid nanoparticles (LNPs) that play a crucial role in safeguarding and delivering therapeutic payloads. In this study, Mitchell et al. conducted an investigation of the efficacy of mRNA drug delivery for the treatment of obesity as well as the potential of gene-editing techniques for the management of hereditary disorders.

Optimizing the Production Process
Prior research has demonstrated that lipidoids possessing branching tails exhibit superior efficacy in delivering mRNA to cells. However, the processes involved in synthesizing these molecules are both time-consuming and expensive. According to Xuexiang Han, a postdoctoral student in the Mitchell Lab and co-first author of the research, we present an innovative approach for the effective and economical production of these lipidoids.

The procedure entails the amalgamation of three chemical compounds, namely an amine “head,” two alkyl epoxide “tails,” and two acyl chloride “branched tails.” The observed similarity between the fully developed lipidoid and a space shuttle affixed to two booster rockets is not a mere coincidence. Han, a college student, recounts that a documentary on the space shuttle left a lasting impression on him due to the remarkable design of the solid rocket boosters that facilitated the shuttle’s entry into orbit. According to Han, it was determined that the addition of two branch tails as “boosters” to the lipidoid might enhance the transportation of mRNA.

The addition of branching tails greatly improved the ability of LNPs containing the new lipidoid to deliver mRNA to specific cells, similar to how boosters help a rocket get into the atmosphere. “We saw a big increase in the production of a hormone that controls metabolism in certain cells after these lipidoids were used to deliver mRNA.” This development is highly promising, particularly in the context of obesity treatment,” states Mitchell.

The article titled “In situ combinatorial synthesis of degradable branched lipidoids for systemic delivery of mRNA therapeutics and gene editors,” authored by Xuexiang Han, Junchao Xu, Ying Xu, Mohamad-Gabriel Alameh, Lulu Xue, Ningqiang Gong, Rakan El-Mayta, Rohan Palanki, Claude C. Warzecha, Gan Zhao, Andrew E. Vaughan, James M. Wilson, Drew Weissman, and Michael J. Mitchell, was published in Nature Communications on February 26, 2024.
