Article Synopsis
  • This project explored how lentil protein (LP) and quinoa protein (QP), in both their natural and modified forms, can be used effectively as carrier materials for encapsulating annatto seed extract through ionic gelation.
  • Various modifications, like enzymatic hydrolysis and N-cationization, aimed to enhance the proteins' encapsulation capabilities while assessing properties such as solubility and gelation temperature.
  • Results showed that while native LP had better encapsulation efficiency compared to QP, certain modifications improved some functional properties but reduced gel formation and had minimal impact on overall encapsulation efficiency.

Angiotensin-converting enzyme inhibitors (ACE-Is) and angiotensin receptor blockers (ARBs) are not recommended during the second and third trimester because of the significant risk of congenital anomalies associated with their use. However, data are scarce, especially regarding their use in the first trimester and about the impact of stopping just before pregnancy. Our study illustrates the profile of the women who used ACE-Is or ARBs during pregnancy and evaluates the impact on perinatal outcomes.

Introduction: Dysarthria, a motor speech disorder caused by muscle weakness or paralysis, severely impacts speech intelligibility and quality of life. The condition is prevalent in motor speech disorders such as Parkinson's disease (PD), atypical parkinsonism such as progressive supranuclear palsy (PSP), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS). Improving intelligibility is not only an outcome that matters to patients but can also play a critical role as an endpoint in clinical research and drug development.

Skeletal muscle regeneration after injury is a complex process involving inflammatory signaling and myoblast activation. Pro-inflammatory cytokines like tumor necrosis factor-alpha (TNF-α) are key mediators, but their effects on gene expression in proliferating myoblasts are unclear. We performed the RNA sequencing of TNF-α treated C2C12 myoblasts to elucidate the signaling pathways and gene networks regulated by TNF-α during myoblast proliferation.

Extracellular Vesicles from Adipose Tissue-Derived Stromal Cells Stimulate Angiogenesis in a Scaffold-Dependent Fashion.

Tissue Eng Regen Med

August 2024

Department of Pathology and Medical Biology, University Medical Center Groningen, University of Groningen, Hanzeplein 1 (EA11), 9713 GZ, Groningen, The Netherlands.

Background: The extracellular vesicles (EVs) secreted by adipose tissue-derived stromal cells (ASC) are microenvironment modulators in tissue regeneration by releasing their molecular cargo, including miRNAs. However, the influence of ASC-derived extracellular vesicles (ASC-EVs) on endothelial cells (ECs) and vascularisation is poorly understood. The present study aimed to determine the pro-angiogenic effects of ASC-EVs and explore their miRNA profile.

Background: CKD patients on hemodialysis (HD) with Staphylococcus aureus (SA) bacteremia present high morbidity, mortality and increased risk of MRSA. Vancomycin is the antibiotic of choice in these cases, it has a narrow therapeutic margin and inadequate dosage generates a risk of toxicity, therefore, the recommendation is to dosage it through serum levels.

Methods: This is a retrospective cohort study in 3 hospitals of third level of complexity in the city of Medellin in which there were differences in the measurement and implementation of vancomycin25 dosage based on trough levels (VL) in patients with chronic kidney disease on hemodialysis (CKD- HD) with uncomplicated bacteremia based infection by methilcillin-resistant Staphyloccocus aureus (MRSA).

Article Synopsis
  • - The rise of breast implant-associated anaplastic large cell lymphoma (ALCL) has prompted the FDA to label silicone and saline implants with a "black-box" warning, pushing for a deeper examination of cancer registry data to validate ALCL cases.
  • - A study analyzing New York State Cancer Registry data from 2007 to 2019 found 28 confirmed ALCL cases among 47,466 patients, with the ICD-O-3 code for ALCL showing high sensitivity and specificity.
  • - The findings suggest that previous studies may have significantly underestimated the risk of ALCL by at least 20%, calling for updated risk assessments and improved case identification methods globally.

Modulation of neuronal activity in human centromedian nucleus during an auditory attention and working memory task.

Neuroimage

August 2024

Department of Physiology, University of Toronto, Canada; Krembil Brain Institute, Leonard St, Toronto Ontario, Canada; Hospital San Vicente Fundación, Rionegro, Colombia; Department of Surgery, University of Toronto, Canada.

Centromedian nucleus (CM) is one of several intralaminar nuclei of the thalamus and is thought to be involved in consciousness, arousal, and attention. CM has been suggested to play a key role in the control of attention, by regulating the flow of information to different brain regions such as the ascending reticular system, basal ganglia, and cortex. While the neurophysiology of attention in visual and auditory systems has been studied in animal models, combined single unit and LFP recordings in human have not, to our knowledge, been reported.

  • UNC93B1 is a protein involved in signaling for Toll-like receptors, which are important for the immune response.
  • Mutations in UNC93B1 (I317M, G325C, L330R, R466S, and R525P) have been linked to conditions like systemic lupus erythematosus (SLE) and chilblain lupus (CBL), exhibiting both autosomal dominant and recessive inheritance patterns.
  • Different mutations impact the activity of TLR7 and TLR8 differently, suggesting that specific mutations in UNC93B1 lead to varying disease mechanisms for SLE and CBL.
