Characterizing molecular underpinnings of plastic traits and balanced polymorphisms represent two important goals of evolutionary biology. Fire ant gynes (pre-reproductive queens) provide an ideal system to study potential links between these phenomena because they exhibit both supergene-mediated polymorphism and nutritional plasticity in weight and colony-founding behavior. Gynes with the inversion supergene haplotype are lightweight and depend on existing workers to initiate reproduction.

Article Synopsis
  • - Large bowel obstruction (LBO) is relatively rare, often caused by colorectal adenocarcinoma, and it typically presents with symptoms like abdominal pain, constipation, and nausea; a CT scan is crucial for diagnosis.
  • - A case study of a 41-year-old male showed severe LBO after a hernia repair, requiring emergency surgery due to findings of a blocked sigmoid colon and complications like pneumatosis.
  • - Diverticulitis, which is increasingly affecting younger individuals, can lead to bowel obstructions and serious complications; educating all patients about risk factors, including diet and surgical history, is important.

Rationale: Acute exacerbations of chronic obstructive pulmonary disease (AECOPDs) are heterogeneous. Machine learning (ML) has previously been used to dissect some of the heterogeneity in COPD. The widespread adoption of electronic health records (EHRs) has led to the rapid accumulation of large amounts of patient data as part of routine clinical care.

Trichinella murrelli Pozio and La Rosa, 2000, is the primary sylvatic trichinellid encountered in temperate North America. During a survey for Sarcocystis in wild canids, a single worm matching the morphology of encapsulated Trichinella was observed in a muscle tissue squash from a gray fox male originating from Pennsylvania. The worm was photographed and then separated from the host tissue by artificial digestion, and genomic DNA was extracted from the worm.

Article Synopsis
  • The circadian clock in plants regulates processes like root nitrate uptake, helping optimize resource use and improve agricultural practices.
  • Understanding the rhythmic expression of the NITRATE TRANSPORTER 2.1 (NRT2.1) gene, which is important for nitrate absorption, reveals that its activity is controlled by the circadian clock and influenced by the transcription factor LUX ARRHYTHMO (LUX).
  • This research suggests that timing nitrate application can affect gene expression and uptake, linking biological rhythms with potential eco-friendly farming strategies.
