Biofloc technology is an aquaculture production system that has gained popularity with tilapia production. Probiotics provide benefits for the host and/or aquatic environments by both regulating and modulating microbial communities and their metabolites. When a probiotic feed is combined with a biofloc system, the production amount may be improved through better fish growth, disease resistance, and/or improved water quality by reducing organic matter and stabilizing metrics such as pH and components of the nitrogen cycle.

We study the kinetics of vapor-liquid and vapor-solid phase separation of a hydrodynamics preserving three-dimensional one-component Lennard Jones system in the presence of an external gravitational field using extensive molecular dynamic simulation. A bicontinuous domain structure is formed when the homogeneous system near the critical density is quenched inside the coexistence region. In the absence of gravity, the domain morphology is statistically self-similar and the length scale grows as per the existing laws.

Objective: Symptomatic thoracic disc herniations (TDH) are relatively rare and can be discovered incidentally on neuroimaging. Surgical interventions for TDH represent only 4 % of all surgeries performed for intervertebral disc pathologies, which are most commonly indicated for myelopathy and radiculopathy. Given the absence of publications on rates of readmissions following hospitalization for TDH, we aim to establish baseline metrics for the 90-day all-cause readmission rates and pertinent risk factors.

Background: Pediatric patients with cancer have limited options to self-manage their health while they are undergoing treatments in the hospital and after they are discharged to their homes. Extended reality (ER) using head-mounted displays has emerged as an immersive method of improving pain and mental health and promoting health-enhancing physical activity among a variety of clinical groups, but there is currently no established protocol for improving both physical and mental health in pediatric cancer rehabilitation.

Objective: This phase I, pilot, feasibility randomized controlled trial aims to investigate the potential effects of a 14-week ER program on physical activity participation and indicators of health among pediatric patients with cancer who undergo bone marrow transplantation.

Article Synopsis
  • Helicobacter pylori is a type 1 carcinogen linked to gastric ulcers and cancer, and research by the Seattle Structural Genomics Center for Infectious Disease focuses on potential treatments targeting this bacterium.
  • The study reports on the purification and crystallization of H. pylori biotin protein ligase (HpBPL), an enzyme that plays a crucial role in important metabolic processes and helps H. pylori thrive in the acidic environment of the stomach.
  • Despite having low sequence identity with similar proteins, HpBPL shares significant structural similarities with Mycobacterium tuberculosis biotin protein ligase, indicating potential for developing inhibitors that could be effective against HpBPL.

We demonstrate that in situ coherent diffractive imaging (CDI), which leverages the coherent interference between strong and weak beams to illuminate static and dynamic structures, can serve as a highly dose-efficient imaging method. At low doses, in situ CDI can achieve higher resolution than perfect lenses with the point spread function as a delta function. Both our numerical simulations and experimental results demonstrate that combining in situ CDI with ptychography can reduce the required dose by up to two orders of magnitude compared with ptychography alone.

Article Synopsis
  • This study evaluated functional lumen imaging probe (FLIP) metrics in obese patients, both surgically naïve and those who had undergone bariatric surgeries like sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB).
  • Researchers found that common symptoms were dysphagia and chest pain across all patient groups, with notable differences in FLIP response patterns, particularly in patients who had bariatric surgery.
  • Despite many patients showing FLIP abnormalities, these did not correlate with esophageal symptoms or high-resolution manometry (HRM) findings, indicating a need for further investigation into esophageal issues in this population.

Article Synopsis
  • - Loneliness has a complex genetic basis, affecting gene expression linked to inflammation and immune response, but previous studies hadn’t explored how DNA methylation patterns relate to this.
  • - In a study involving 281 adult twins' DNA, researchers found no significant methylation differences at the genome-wide level, but identified 25 suggestive sites associated with genes related to inflammation.
  • - The study showed a strong correlation between loneliness and accelerated epigenetic aging, indicating that higher loneliness levels might reflect faster biological aging across various systems in the body.

Understanding how a macromolecule's primary sequence governs its conformational landscape is crucial for elucidating its function, yet these design principles are still emerging for macromolecules with intrinsic disorder. Herein, we introduce a high-throughput workflow that implements a practical colorimetric conformational assay, introduces a semi-automated sequencing protocol using MALDI-MS/MS, and develops a generalizable sequence-structure algorithm. Using a model system of 20mer peptidomimetics containing polar glycine and hydrophobic -butylglycine residues, we identified nine classifications of conformational disorder and isolated 122 unique sequences across varied compositions and conformations.
