From a bimodal to a multi-stage view on trypanosomes' differential RNA editing.

Significant variations in the abundance of mitochondrial RNA processing proteins and their target RNAs across trypanosome life stages present an opportunity to explore the regulatory mechanisms that drive these changes. Utilizing omics approaches can uncover unconventional targets, aiding our understanding of the parasites' adaptation and enabling targeted interventions for differentiation.

Enhancement of Hippocampal-Thalamocortical Temporal Coordination during Slow-Frequency Long-Duration Anterior Thalamic Spindles.

Temporal nesting of cortical slow oscillations, thalamic spindles, and hippocampal ripples indicates multiregional neuronal interactions required for memory consolidation. However, how the thalamic activity during spindles organizes hippocampal dynamics remains largely undetermined. We analyzed simultaneous recordings of anterodorsal thalamus and CA1 in male mice to determine the contribution of thalamic spindles in cross-regional synchronization.

The essential role of hippocampo-cortical connections in temporal coordination of spindles and ripples.

The predominant activity of slow wave sleep is cortical slow oscillations (SOs), thalamic spindles and hippocampal sharp wave ripples. While the precise temporal nesting of these rhythms was shown to be essential for memory consolidation, the coordination mechanism is poorly understood. Here we develop a minimal hippocampo-cortico-thalamic network that can explain the mechanism underlying the SO-spindle-ripple coupling indicating of the succession of regional neuronal interactions.

Optimized dose of synthetic analogues of Monophosphoryl lipid A as an effective alternative for formulating recombinant human papillomavirus vaccine.

Adjuvants are a crucial component of recombinant vaccines such as the human papillomavirus (HPV) vaccine. Monophosphoryl lipid A (MPL) extracted from Salmonella Minnesota lipopolysaccharide is used as an adjuvant for the HPV vaccine. Due to the limitations in accessibility and reproducibility of MPL, investigating synthetic analogues of MPL (synMPL) is urgently needed to overcome these limitations.

Miniature Diamond-Based Fiber Optic Pressure Sensor with Dual Polymer-Ceramic Adhesives.

Diamond is a good candidate for harsh environment sensing due to its high melting temperature, Young's modulus, and thermal conductivity. A sensor made of diamond will be even more promising when combined with some advantages of optical sensing (i.e.

Immunogenicity of HPV and HBV vaccines: adjuvanticity of synthetic analogs of monophosphoryl lipid A combined with aluminum hydroxide.

Monophosphoryl lipid A (MPL), a purified and detoxified product of lipopolysaccharide (LPS) of Salmonella minnesota R595, has been used as an adjuvant in different vaccines. In this study, the efficacy of human papillomaviruses (HPV) and hepatitis B virus (HBV) vaccines formulated with aluminum hydroxide combined with two different synthetic MPLs, 3D-(6-acyl)-PHAD or 3D-PHAD, or aluminum hydroxide combined with the mixtures of such MPLs, has been assessed. The immunogenicity in female BALB/c mice was verified by two intramuscular injections of differently formulated HPV and HBV vaccines and the total immunoglobulin G (IgG) antibody response was considered to compare the employed adjuvants.

Proteomics investigation of molecular mechanisms affected by EnBase culture system in anti-VEGF fab fragment producing E. coli BL21 (DE3).

Aggregation of recombinant proteins, a major problem in E. coli expression system, is improved by using EnBase culture system based on slow release of glucose. In the present study, to understand the intracellular mechanisms involved in increased solubility of the target recombinant protein through EnBase system, the effect of this system was investigated on E.

Proteomics Profiling of Chimeric-Truncated Tissue Plasminogen activator Producing- Chinese Hamster Ovary Cells Cultivated in a Chemically Defined Medium Supplemented with Protein Hydrolysates.

Background: Culture media enrichment through the addition of protein hydrolysates is beneficial for achieving higher protein expression.

Methods: In this study, designing the optimum mixture of four soy and casein-derived hydrolysates was successfully performed by design of experiment and specific productivity increased in all predicted combinations. Protein profile of recombinant CHO (rCHO) cells producing tissue plasminogen activator in a serum-free medium (SFM) supplemented with designed hydrolysate additives was compared to that of rCHO cells cultivated in SFM.
