Background: Sleeve gastrectomy (SG) is the most frequently performed bariatric surgery worldwide, offering effective weight loss and improvement in metabolic conditions. However, one of its major complications is the exacerbation or development of gastroesophageal reflux disease (GERD), affecting over 30% of patients. While Roux-en-Y gastric bypass (RYGB) is often the preferred alternative for patients with pre-existing GERD, it may not be suitable for all patients due to contraindications or patient preference.

Microorganisms have co-evolved with a variety of plants and animals, developing complex symbiotic relationships with their hosts and the environment. The diversity of symbionts acquired over time help their hosts to adapt, survive, and evolve more rapidly and efficiently, improving fitness across the lifespan. Understanding these synergistic relationships between humans and their endogenous microbiota may provide valuable information on human physiology and on potential mechanisms associated with the onset of diseases.

Article Synopsis
  • Hymenaea stigonocarpa has thick cuticles on its leaves and structural adaptations that may reduce herbicide absorption, leading to the hypothesis of its resistance to glyphosate.
  • Testing different doses of glyphosate revealed that while plant height and leaf count decreased, and leaf fall affected photosynthesis, there were no visible signs of herbicide toxicity or oxidative stress.
  • The study confirmed that H. stigonocarpa is tolerant to glyphosate, with lower doses leading to positive growth and photosynthetic responses, suggesting a possible hormetic effect.

  • Ocular toxoplasmosis (OT) is an eye condition caused by a parasite that leads to inflammation of the retina and choroid, affecting vision; genetic variations in cytokine genes may influence susceptibility to this disease.
  • A study categorized Brazilian participants with positive toxoplasmosis serology into two groups based on the presence or absence of OT, along with a control group without infection, to examine specific gene polymorphisms' roles.
  • Findings indicated that individuals with the C/C genotype of a particular gene variant were less likely to develop OT, suggesting that this genetic factor may offer protection against the condition in the studied population.

Polycyclic aromatic hydrocarbons (PAHs) are widespread across the environment and humans are unavoidably and constantly exposed to them. As lipophilic contaminants, these substances tend to accumulate in fatty tissues as adipose tissue and exposure to these endocrine disruptors has been associated with severe health hazards including prevalence and incidence of obesity. Previous studies have shown significantly higher concentrations of PAHs in adipose tissue compared to other human samples, such as urine and plasma, which are typically used for PAHs assessment.

One of the most pressing questions we face as biologists is to understand how climate change will affect the evolutionary dynamics of natural populations and how these dynamics will in turn affect population recovery. Increasing evidence shows that sexual selection favors population viability and local adaptation. However, sexual selection can also foster sexual conflict and drive the evolution of male harm to females.
