Successful Desensitization With ELX/TEZ/IVA.

Elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) was given US Food and Drug Administration approval based on its therapeutic benefits to treat patients with cystic fibrosis (CF) who had at least 1 allele of the CF transmembrane conductance regulator (CFTR) with phenylalanine deleted at position 508 (F508del). The increase in genotyping studies has increased the frequency of use of CFTR modulators; however, severe allergic reactions to CFTR modulators have also been described. It is critical to avoid the offending medication and select alternative treatments while dealing with drug allergies.

Production and biological activities of exopolysaccharides synthesized by thermophilic bacilli isolated from hot springs in Türkiye.

Thermophilic bacteria able to produce exopolysaccharides (EPSs) have become attractive in recent years. EPSs synthesized by thermophiles are worth investigating due to their unexplored structural and biological properties. In this study, EPSs from thermophilic, Gram-positive bacterial isolates were purified and tested for their biological activities.

Is It Possible to Use Inflammatory Markers as Potential Biomarkers for Chronic Urticaria?

This study aimed to determine whether the neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) at admission affect the transition of pediatric patients diagnosed with acute spontaneous urticaria to chronic urticaria. This study included 390 patients who presented to the Department of Pediatrics at Akdeniz University Hospital with acute spontaneous urticaria between January 2020 and December 2022. A statistical comparison was made between the hematological parameters of patients who developed chronic urticaria and those who did not.

Characterization and biological activities of a novel exopolysaccharide produced from Geobacillus thermodenitrificans HBB 111 strain.

In this study, EPS production conditions of Geobacillus thermodenitrificans HBB 111, a thermophilic microorganism, were optimized and the amount of produced EPS (EPS 111) was found to be 44.0 mg/L. EPS 111 was purified using ion exchange chromatography and gel filtration chromatography, and a single type of exopolysaccharide was obtained.

Optochemical control of slow-wave sleep in the nucleus accumbens of male mice by a photoactivatable allosteric modulator of adenosine A receptors.

Optochemistry, an emerging pharmacologic approach in which light is used to selectively activate or deactivate molecules, has the potential to alleviate symptoms, cure diseases, and improve quality of life while preventing uncontrolled drug effects. The development of in-vivo applications for optochemistry to render brain cells photoresponsive without relying on genetic engineering has been progressing slowly. The nucleus accumbens (NAc) is a region for the regulation of slow-wave sleep (SWS) through the integration of motivational stimuli.

Sleep-Deep-Learner is taught sleep-wake scoring by the end-user to complete each record in their style.

Sleep-wake scoring is a time-consuming, tedious but essential component of clinical and preclinical sleep research. Sleep scoring is even more laborious and challenging in rodents due to the smaller EEG amplitude differences between states and the rapid state transitions which necessitate scoring in shorter epochs. Although many automated rodent sleep scoring methods exist, they do not perform as well when scoring new datasets, especially those which involve changes in the EEG/EMG profile.

Preparation of PEGylated uricase attached magnetic nanowires and application for uric acid oxidation.

The present study aims to immobilize the uricase enzyme on magnetic nanowires and to examine its potential for use in the treatment of gout. For this, Au/Ni/Au nanowires were synthesized using a polycarbonate membrane template by the sequential electrodeposition of Au, Ni, and Au, respectively. The uricase enzyme was covalently attached to these nanowires and was also coated with PEG.

Factors affecting formula compliance of infants with IgE mediated cow's milk protein allergy during the pandemic.

Introduction: Cow's milk protein allergy (CMPA) is the most commonly encountered food allergy in the world, usually seen in infants under the age of 2 years. This study aims to determine the factors including COVID-19 affecting formula compliance of CMPA patients.

Methods: This study is a prospective, observational study based on 10 different Paediatric Allergy-Immunology clinics in Turkey.

The Asthma Risk Is Increased in Children with Severe Allergic Rhinitis.

Objective: The aim of the study was to evaluate the allergic rhinitis severity, to identify risk fac- tors associated with asthma, and to determine the frequency of comorbid conditions in allergic rhinitis patients with positive skin prick test.

Materials And Methods: Clinical characteristics of pediatric patients with allergic rhinitis were investigated. The frequency of comorbidities and risk factors for asthma development were investigated.

Circuits and components of delta wave regulation.

Sleep is vital and the deepest stages of sleep occur within Non-rapid-eye-movement sleep (NREM), defined by high electroencephalographic power in the delta (~0.5-4 Hz) wave frequency range. Delta waves are thought to facilitate a myriad of physical and mental health functions.

Differential effect of sleep deprivation on place cell representations, sleep architecture, and memory in young and old mice.

Poor sleep quality is associated with age-related cognitive decline, and whether reversal of these alterations is possible is unknown. In this study, we report how sleep deprivation (SD) affects hippocampal representations, sleep patterns, and memory in young and old mice. After training in a hippocampus-dependent object-place recognition (OPR) task, control animals sleep ad libitum, although experimental animals undergo 5 h of SD, followed by recovery sleep.

Clinical phenotypes of childhood food allergies based on immune mechanisms: A multicenter study.

Food allergies (FA) are an important public health concern that place a major burden on the lives of children and their families. The complex pathogenesis of FAs results in multisystemic and heterogenous clinical presentations. To evaluate, according to immune mechanisms, the characteristics and risk factors of childhood FA in Turkey.

Inulinase Immobilized Lectin Affinity Magnetic Nanoparticles for Inulin Hydrolysis.

In this presented paper, concanavalin A-modified cysteine-functionalized FeO/Ag core/shell magnetic nanoparticles were synthesized and used as a support material for inulinase enzyme, which has been intensively used for the preparation of high-fructose syrup by hydrolyzing inulin. Inulinase adsorption capacity of Con A-functionalized Ag-coated magnetic nanoparticles was optimized by changing medium pH, temperature, and initial inulinase concentration, and maximum inulinase adsorption capacity was found to be 655.32 mg/g nanoparticle by using 1.

Broadly effective metabolic and immune recovery with C5 inhibition in CHAPLE disease.

Complement hyperactivation, angiopathic thrombosis and protein-losing enteropathy (CHAPLE disease) is a lethal disease caused by genetic loss of the complement regulatory protein CD55, leading to overactivation of complement and innate immunity together with immunodeficiency due to immunoglobulin wasting in the intestine. We report in vivo human data accumulated using the complement C5 inhibitor eculizumab for the medical treatment of patients with CHAPLE disease. We observed cessation of gastrointestinal pathology together with restoration of normal immunity and metabolism.

Hematopoietic stem cell transplantation in CD40 ligand deficiency: A single-center experience.

Deficiency of the CD40L, expressed on the surface of T lymphocytes, is caused by mutations in the glycoprotein CD40L (CD154) gene. Resulting defective humoral and cellular responses cause a clinical presentation that includes recurrent sinopulmonary bacterial infections, opportunistic infections, sclerosing cholangitis, neutropenia, and autoimmune manifestations. HSCT represents the only curative treatment modality.

Mutational landscape of severe combined immunodeficiency patients from Turkey.

Severe combined immunodeficiency (SCID) has a diverse genetic aetiology, where a clinical phenotype, caused by single and/or multiple gene variants, can give rise to multiple presentations. The advent of next-generation sequencing (NGS) has recently enabled rapid identification of the molecular aetiology of SCID, which is crucial for prognosis and treatment strategies. We sought to identify the genetic aetiology of various phenotypes of SCIDs and assessed both clinical and immunologic characteristics associated with gene variants.
