Article Synopsis
- Morbid obesity leads to significant health, social, and economic issues, often requiring surgical interventions like bariatric surgery that result in massive weight loss.
- This study evaluates skin biopsies from nine patients before and after bariatric surgery to analyze histological changes, using various staining techniques and statistical methods to assess collagen, fibrosis, vascularity, and adipocyte populations.
- Results indicate that post-bariatric surgery patients experience increased fibrosis and decreased collagen and elastic fibers, as well as reduced vascular proliferation in the skin after massive weight loss.
Article Synopsis
- Eggs are rich in protein and nutrients, and they affect gene expression, which can impact health.
- A study was conducted on rats to see how whole egg consumption affects gene expression in the prefrontal cortex, liver, kidney, and visceral adipose tissue.
- The results showed that egg consumption altered the expression of 52 genes in the prefrontal cortex and identified important metabolic pathways impacted, particularly glutathione metabolism and cholesterol biosynthesis.
Background: Polycystic ovary syndrome (PCOS) is an endocrine disorder that affects 10% of reproductive-aged women and leads to hyperandrogenism, anovulation, and infertility. PCOS has been associated with elevated serum homocysteine as well as altered methylation status; however, characterization of one-carbon metabolism (OCM) in PCOS remains incomplete.
Objectives: The aim of our research was to assess OCM in a letrozole-induced Sprague Dawley rat model of PCOS.
Article Synopsis
- Nutrigenomic research suggests that Type 2 Diabetes Mellitus (T2DM) results from interactions between genetics, lifestyle, and diet, emphasizing the potential impact of nutrient-rich foods like eggs on gene expression.
- A study was conducted with Zucker Diabetic Fatty (ZDF) rats to investigate how whole egg consumption affects microRNA and mRNA expression in various tissues related to T2DM, revealing 9 microRNAs and 583 genes that changed with egg consumption.
- Notably, whole egg diets enhanced the expression of 12 genes involved in glutathione metabolism in the liver and kidney, suggesting that eggs might help alleviate negative effects associated with T2DM by supporting detoxification and reducing oxidative stress.
The role of long-range dispersal in the coexistence of sexual and asexual relatives in a population of hermaphrodite flowering plants is investigated. In these populations, growth and reproduction often occur during a sedentary stage that is then followed by dispersal of propagules. These two stages are clearly distinguishable and show strong seasonality.

We propose a cellular automaton model where local rules focus on fertilization and colonization. This model produces rich sets of data which are then studied by means of spatial statistics.
