A signaling inspired synthetic toolkit for efficient production of tyrosine phosphorylated proteins.

Tyrosine phosphorylation is an important post-translational modification that regulates many biochemical signaling networks in multicellular organisms. To date, 46,000 tyrosines have been observed in human proteins, but relatively little is known about the function and regulation of most of these sites. A major challenge has been producing recombinant phospho-proteins in order to test the effects of phosphorylation.

A bioinformatic approach for the prediction and functional classification of Toxoplasma gondii long non-coding RNAs.

Long non-coding RNAs (lncRNAs) have emerged as significant players in diverse cellular processes, including cell differentiation. Advancements in computational methodologies have facilitated the prediction of lncRNA functions, enabling insights even in non-model organisms like pathogenic parasites, in roles such as parasite development, antigenic variation, and epigenetics. In this work, we focus on the apicomplexan Toxoplasma gondii differentiation process, where the infective stage, tachyzoite, can develop into the cysted stage, bradyzoite, under stress conditions.

A Rare Co-occurrence of Williams Syndrome and 𝘛𝘕𝘒2 Gene-Related Epilepsy.

Williams syndrome is a multisystem disorder characterized by developmental delay, characteristic facial features, growth abnormalities, and cardiovascular abnormalities. The disorder is an autosomal dominant genetic syndrome that occurs due to microdeletion at chromosomal locus 7q11.23.

Identification of subtelomeric cluster-genes associated to sexual stage in Toxoplasma gondii.

Toxoplasma gondii is an obligate intracellular parasite with sexual reproduction in the intestinal epithelium of felines. The depletion of two gene repressors, AP2XI-2 and AP2XII-1, induces merozoite formation and gene expression towards sexual commitment. Based on RNA-seq datasets of AP2XI-2 and AP2XII-1 knock downs we identified subtelomeric (ST) TgB12 and hypothetical (HP) genes upregulated.

CoDIAC: A comprehensive approach for interaction analysis reveals novel insights into SH2 domain function and regulation.

Protein domains are conserved structural and functional units and are the functional building blocks of proteins. Evolutionary expansion means that domain families are often represented by many members in a species, which are found in various configurations with other domains, which have evolved new specificity for interacting partners. Here, we develop a structure-based interface analysis to comprehensively map domain interfaces from available experimental and predicted structures, including interfaces with other macromolecules and intraprotein interfaces (such as might exist between domains in a protein).

Purpose: Septoplasty and rhinoplasty are common otolaryngological procedures, often combined as septorhinoplasty (SRP), offering aesthetic and functional benefits. These surgeries are believed to potentially risk postoperative infections due to natural bacterial flora in the nares. This study evaluates the effectiveness of prophylactic antibiotics in reducing post-surgical infection complications.

Safe plant Hsp90 adjuvants elicit an effective immune response against SARS-CoV2-derived RBD antigen.

To better understand the role of pHsp90 adjuvant in immune response modulation, we proposed the use of the Receptor Binding Domain (RBD) of the Spike protein of SARS-CoV2, the principal candidate in the design of subunit vaccines. We evaluated the humoral and cellular immune responses against RBD through the strategy "protein mixture" (Adjuvant + Antigen). The rRBD adjuvanted with rAtHsp81.

A Randomized Control Study to Assess the Efficacy of Intrathecal Morphine in Patients on Patient-Controlled Analgesia Pump With Morphine for Postoperative Pain Relief After Elective Laparotomy.

Introduction Laparotomy is associated with significant prolonged postoperative pain, which can cause an adverse neuroendocrine stress response. Intrathecal morphine (ITM) retains an important place in pain management after major laparotomy since it is easier to administer and has a relatively lesser possibility of failure and technical difficulty. Aim The study aims to compare the effect of the administration of ITM with intravenous (IV) morphine administered by a patient-controlled analgesia (PCA) pump on postoperative analgesia after elective laparotomy.

Titania/graphene nanocomposites from scalable gas-phase synthesis for high-capacity and high-stability sodium-ion battery anodes.

In sodium-ion batteries (SIBs), TiOor sodium titanates are discussed as cost-effective anode material. The use of ultrafine TiOparticles overcomes the effect of intrinsically low electronic and ionic conductivity that otherwise limits the electrochemical performance and thus its Na-ion storage capacity. Especially, TiOnanoparticles integrated in a highly conductive, large surface-area, and stable graphene matrix can achieve an exceptional electrochemical rate performance, durability, and increase in capacity.

Importance: COVID-19 in pediatric patients with acute lymphoblastic leukemia or lymphoma (ALL/LLy) has not been described in detail and may affect chemotherapy administration and long-term outcomes.

Objective: To describe the clinical presentation of COVID-19 and chemotherapy modifications in pediatric patients with ALL/LLy.

Design, Setting, And Participants: This is a retrospective case series of patients at St Jude Children's Research Hospital and its affiliate sites with newly diagnosed ALL/LLy who were treated on the Total XVII protocol (NCT03117751) between March 30, 2020, and June 20, 2022.

Mechanisms of adaptation and evolution in Toxoplasma gondii.

Toxoplasma has high host flexibility, infecting all nucleated cells of mammals and birds. This implies that during its infective process the parasite must constantly adapt to different environmental situations, which in turn leads to modifications in its metabolism, regulation of gene transcription, translation of mRNAs and stage specific factors. There are conserved pathways that support these adaptations, which we aim to elucidate in this review.

Proteomics Applications in : Unveiling the Host-Parasite Interactions and Therapeutic Target Discovery.

, a protozoan parasite with the ability to infect various warm-blooded vertebrates, including humans, is the causative agent of toxoplasmosis. This infection poses significant risks, leading to severe complications in immunocompromised individuals and potentially affecting the fetus through congenital transmission. A comprehensive understanding of the intricate molecular interactions between and its host is pivotal for the development of effective therapeutic strategies.

Competing discourses as barriers to change in rehabilitation nursing: a discourse analysis.

Introduction: The power of action research to create change by anchoring research results in practice was challenged in an action research project at a specialized rehabilitation unit for persons with acquired spinal cord injury. Despite the co-researchers' new insights, approaches, and actions supporting patient participation, it was not possible to change the basic conditions for the practicing of nursing. We aimed to raise awareness of the mechanisms that govern barriers by exploring these barriers as experienced by nurses in their effort to change their practice to improve patient participation.

A human mesenchymal spheroid prototype to replace moderate severity animal procedures in leukaemia drug testing.

Patient derived xenograft (PDX) models are regarded as gold standard preclinical models in leukaemia research, especially in testing new drug combinations where typically 45-50 mice are used per assay. 9000 animal experiments are performed annually in the UK in leukaemia research with these expensive procedures being classed as moderate severity, meaning they cause significant pain, suffering and visible distress to animal's state. Furthermore, not all clinical leukaemia samples engraft and when they do data turnaround time can be between 6-12 months.

Evaluation of topotecan and 10-hydroxycamptothecin on Toxoplasma gondii: Implications on baseline DNA damage and repair efficiency.

Toxoplasma gondii is an obligate intracellular parasite in the phylum Apicomplexa that causes toxoplasmosis in humans and animals worldwide. Despite its prevalence, there is currently no effective vaccine or treatment for chronic infection. Although there are therapies against the acute stage, prolonged use is toxic and poorly tolerated.

Background: The wMel strain of Wolbachia has been successfully introduced into Aedes aegypti mosquitoes and has been shown to reduce the transmission of dengue and other Aedes-borne viruses. Here we report the entomological results from phased, large-scale releases of Wolbachia infected Ae. aegypti mosquitoes throughout three contiguous cities located in the Aburrá Valley, Colombia.

Single-Grating Monolithic Spatial Heterodyne Raman Spectrometer: An Investigation on the Effects of Detector Selection.

Spatial heterodyne Raman spectrometers (SHRSs) are modified forms of Michelson interferometers, except the mirrors in a Michelson interferometer are replaced with stationary diffraction gratings. This design removes the need for an entrance slit, as is the case in a dispersive spectrometer, and removes the need to scan the spectrum by using a moving mirror in a modern Michelson interferometer. In previous studies, various SHRS variants, such as free-standing two-grating SHRS, single-grating SHRS (1g-SHRS), monolithic SHRS (mSHRS), and single-grating mSHRS (1g-mSHRS), have been evaluated.

Histone variant H2B.Z acetylation is necessary for maintenance of Toxoplasma gondii biological fitness.

Through regulation of DNA packaging, histone proteins are fundamental to a wide array of biological processes. A variety of post-translational modifications (PTMs), including acetylation, constitute a proposed histone code that is interpreted by "reader" proteins to modulate chromatin structure. Canonical histones can be replaced with variant versions that add an additional layer of regulatory complexity.
