Human 5-lipoxygenase (LOX) is a non-heme, Fe-containing LOX which catalyses the conversion of arachidonic acid (AA) to leukotriene A (LTA). LTA is subsequently converted to cysteinyl-LTs and LTB that cause bronchoconstriction and act as chemotactic and chemokinetic agent on human leukocytes, respectively. Leukotrienes play significant roles in inflammation in asthma, cardiovascular diseases, allergic rhinitis, atopic dermatitis, inflammatory bowel disease, rheumatoid arthritis, psoriasis and many more.

Dissociative symptoms are a frequent complication in posttraumatic stress disorders affecting about a third of all PTSD patients. While theoretical models predict a physiological hypoarousal during posttraumatic dissociations, empirical evidence is lacking. We addressed this by studying spontaneously occurring dissociative symptoms and related heart rate changes in an ecological momentary assessment.

Despite their global distribution and commercial value, little is known about their movement ecology and its role in the co-existence of sympatric mullet species. Gaps in knowledge about migratory behaviour, seasonal occurrence, and movement scales have also impeded effective management, highlighting the need for further research.

Background: The broad use of bedaquiline and pretomanid as the mainstay of new regimens to combat tuberculosis is a risk due to increasing bedaquiline resistance. We aimed to assess the safety, bactericidal activity, and pharmacokinetics of BTZ-043, a first-in-class DprE1 inhibitor with strong bactericidal activity in murine models.
Methods: This open-label, dose-expansion, randomised, controlled, phase 1b/2a trial was conducted in two specialised tuberculosis sites in Cape Town, South Africa.

Envenomation accidents are usually diagnosed at the hospital through signs and symptoms assessment such as short breath, dizziness and vomiting, numbness, swilling, bruising, or bleeding around the affected site. However, this traditional method provides inaccurate diagnosis given the interface between snakebites and scorpion stings symptoms. Therefore, early determination of bites/stings source would help healthcare professionals select the suitable treatment for patients, thus improving envenomation management.

A prolific multi-product sesterterpene synthase CbTPS1 is characterized from the medicinal Brassicaceae plant Capsella bursa-pastoris. Twenty different sesterterpenes including 16 undescribed compounds, possessing 10 different mono-/di-/tri-/tetra-/penta-carbocyclic skeletons, including the unique 15-membered macrocyclic and 24(15→14)-abeo-capbuane scaffolds, are isolated and structurally elucidated from engineered Escherichia coli strains expressing CbTPS1. Site-directed mutagenesis assisted by molecular dynamics simulations resulted in the variant L354M with up to 13.

The Rat-1 cell line was established as a subclone of the parental rat fibroblastoid line F2408, derived from Fisher 344 rat embryos. Rat-1 cells are widely used in various research fields, especially in cancer biology, to study the effects of oncogenes on cell proliferation. They are also crucial for investigating signal transduction pathways and play a key role in drug testing and pharmacological studies due to their rapid proliferation.

Background And Aims: The therapeutic management of fistulas presents significant challenges, often involving both conservative and surgical approaches. Despite these interventions, recurrence and postoperative mortality rates remain high. Endoscopic stent insertion into the fistula, along with the creation of a stent stoma, may offer a promising alternative for patients who fail surgical or conservative therapies.

Quantum walks on photonic platforms represent a physics-rich framework for quantum measurements, simulations and universal computing. Dynamic reconfigurability of photonic circuitry is key to controlling the walk and retrieving its full operation potential. Universal quantum processing schemes based on time-bin encoding in gated fibre loops have been proposed but not demonstrated yet, mainly due to gate inefficiencies.

Herbivorous insects need to cope with changing host plant biochemistry caused by abiotic and biotic impacts, to meet their dietary requirements. Larvae of the multivoltine European grapevine moth Lobesia botrana, one of the main insect pests in viticulture, feed on both flowers and berries. The nutritional value and defence compounds of these organs are changing with plant phenology and are affected by climate change which may accordingly alter plant-insect interactions.

Small molecule machine learning aims to predict chemical, biochemical, or biological properties from molecular structures, with applications such as toxicity prediction, ligand binding, and pharmacokinetics. A recent trend is developing end-to-end models that avoid explicit domain knowledge. These models assume no coverage bias in training and evaluation data, meaning the data are representative of the true distribution.

The neural extracellular matrix (ECM) accumulates in the form of perineuronal nets (PNNs), particularly around fast-spiking GABAergic interneurons in the cortex and hippocampus, but also around synapses and in association with the axon initial segments (AIS) and nodes of Ranvier. Increasing evidence highlights the role of Neurocan (Ncan), a brain-specific component of ECM, in the pathophysiology of neuropsychiatric disorders like bipolar disorder and schizophrenia. Ncan localizes at PNNs, perisynaptically, and at the nodes of Ranvier and the AIS, highlighting its potential role in regulating axonal excitability.
