The growth of animals is influenced by various factors including genetics, nutrition, and environmental conditions. This study focuses on understanding the traditional growth phases of Iberian pigs raised in semi-free-range environments prior to the finishing period within the Mediterranean forest. Using a comprehensive dataset of 5329 pigs, we evaluated the abilities of several mathematical models to predict growth patterns during the early growing and pre-finishing phases.

Extratropical cyclones (ETCs) are the focus of many open questions, spanning from weather to climate and from local to global scales. The relationship between moisture uptake and precipitation over different mesoscale ETC structures remains poorly understood. The availability of moisture parameters to the scientific community through tracer dispersion models benefits the representation of the processes involving moisture, the dynamics of ETCs and the understanding of the associated meteorological fields.

Environmental temperature is increasing while natural populations are forced to adjust their life cycle to new conditions, resulting in the expression of new phenotypic traits. Still, the links between these new environmental conditions and the subsequent phenotypic expressions are not fully explored. Here, we conducted manipulative experiments with embryos of the marine gastropod to assess the effects of warmer temperatures upon shell form.

Brain-derived neurotrophic factor (BDNF) is a potential biomarker of response to treatment in psychiatric disorders. As it plays a role in the pathophysiological development of schizophrenia and bipolar disorder, it is of interest to study its role in predicting therapeutic responses in both conditions. We carried out a systematic review of the literature, looking for differences in baseline BDNF levels and the Val66Met BDNF polymorphism in these disorders between responders and non-responders, and found information showing that the Val/Val genotype and higher baseline BDNF levels may be present in patients that respond successfully to pharmacological and non-pharmacological treatments.

Oleanolic acid (OLA) has beneficial health effects in animals, but in vivo efficacy in monogastric animals is questioned due to its low bioavailability. To gain further insight on the nutritional effects of OLA it was administered as part of a diet. We investigated digestibility and plasma OLA in pigs and the associated influence on growth, organs, digestibility of nutrients and plasma biochemical profile.

We explored the experiences of women with fibromyalgia during the COVID-19 pandemic from a qualitative approach by interviewing eighteen women. We identified seven main themes after performing a thematic analysis: pain description, pain triggers, impact, coping strategies, treatment for pain, pain onset and general situation. In general, pain worsened during the pandemic, and activity restrictions and changes in social interactions were particularly related with that.

Article Synopsis
  • - Rho GTPases, particularly RhoA, act as molecular switches that influence various cellular functions, and a study was conducted using a mouse model to explore RhoA's role in the intestinal lining.
  • - The study found that inhibiting RhoA did not visibly change the mice's appearance but led to increased levels of nuclear β-catenin and chronic activation of Wnt signaling in the intestinal epithelium, which affected cell differentiation but not proliferation.
  • - Older mice showed a notable rise in spontaneous intestinal tumors, suggesting that RhoA is vital for regulating the differentiation of intestinal epithelial cells and helps prevent tumor development through its influence on Wnt signaling.

Article Synopsis
  • - The study investigates the characteristics and effects of the time taken to diagnose systemic lupus erythematosus (SLE) in a Latin American cohort, noting that diagnosis can often be delayed and that SLE may resemble other diseases.
  • - Patients with longer diagnosis times (over 6 months) were often older, female, of Mestizo descent, uninsured, and displayed atypical symptoms, but this delayed diagnosis did not seem to affect their disease progression or mortality rates significantly.
  • - Overall, the research concludes that within this cohort, waiting up to 24 months for an SLE diagnosis, with a median of 6 months, did not lead to worse health outcomes.
