Adapting biological systems for nanoparticle synthesis opens an orthogonal Green direction in nanoscience by reducing the reliance on harsh chemicals and energy-intensive procedures. This study addresses the challenge of efficient catalyst preparation for organic synthesis, focusing on the rapid formation of palladium (Pd) nanoparticles using bacterial cells as a renewable and eco-friendly support. The preparation of catalytically active nanoparticles on the bacterium VKM B-3302 represents a more suitable approach to increase the reaction efficiency due to its resistance to metal salts.

Bacterial meningitis is a severe and life-threatening infection of the central nervous system (CNS), primarily caused by and . This condition carries a high risk of mortality and severe neurological sequelae, such as cognitive impairment and epilepsy. Pain, a central feature of meningitis, results from the activation of nociceptor sensory neurons by inflammatory mediators or bacterial toxins.

Background: Shell and pearl formation in bivalves is a sophisticated biomineralization process that encompasses immunological and mineralization aspects, particularly during shell repair and the initial stages of pearl cultivation when a nucleus is inserted. Here, we describe a novel C-type lectin, HcLec1, isolated and characterized from the freshwater pearl mussel Lea.
Methods: Immune challenge, RNA interference (RNAi) experiments, ELISA, and antibacterial assays were employed to investigate the role of HcLec1 in innate immunity.

The replenishment of our stock of substances that possess a therapeutic potential is an important objective in modern biomedicine. Despite the important advances achieved in chemical synthesis, the natural diversity of organisms and microorganisms remains an important source of biologically active compounds. Here, we report the results of our study of a unique collection containing more than 3,000 samples of yeasts found on the Kamchatka Peninsula, the Kuril Islands, and Sakhalin Island, Russia.

Sulfonamide derivatives have been widely used for pesticide research in recent years. Herein, 1,3,4-oxadiazole sulfonamide derivatives containing a pyrazole structure were synthesized, and their structure-activity relationship was studied. Bioactivity tests showed the remarkable efficacy of most synthesized compounds.
