Despite the thousands of spore germinant receptor operons identified in genomes of bacilli and clostridia, understanding how the three essential receptor components act as a signal transduction machine in germination remains limited. The paper by Amon et al. in this issue uses the classical genetic approach of suppression to define a region of likely interaction between the GerAA and GerAB proteins: it provides a first glimpse into potential events within the receptor complex (J. D. Amon, L. Artzi, and D. Z. Rudner, J Bacteriol 204:e00470-21, 2022, https://doi.org/10.1128/JB.00470-21).

The Role of Pyroptosis-Related Gene Signature and Immune Infiltration in Juvenile Dermatomyositis.

Department of Clinical Laboratory, Central Hospital of Dalian University of Technology, Dalian, 116033, People's Republic of China.
Objective: Juvenile dermatomyositis (JDM) is a complex autoimmune disease, and its pathogenesis remains poorly understood. Building upon previous research on the immunological and inflammatory aspects of JDM, this study aims to investigate the role of pyroptosis in the pathogenesis of JDM using a comprehensive bioinformatics approach.
Methods: Two microarray datasets (GSE3307 and GSE11971) were obtained from the Gene Expression Omnibus database, and a list of 62 pyroptosis-related genes was compiled.
Therapeutic efficacy of against phenylhydrazine-induced hemolytic anemia in rats.

Background & Aim: Hemolytic anemia is a blood disorder whose incidence is increasing in the world in recent years especially after the pandemic. Conventional treatments include use of steroids and immunosuppresants that are accompanied by numerous adverse effects. With growing interest in using complex multi-component formulations for multi-targeted therapy, the present study aims to investigate the therapeutic efficacy of a traditional herbomineral preparation, , which has been traditionally used as a supplement in iron-deficiency anemia, against phenylhydrazine-induced hemolytic anemia in rodent models.

Molecular recognition and detection of small bioactive molecules, like neurotransmitters, remain a challenge for chemists, whereas nature found an elegant solution in form of protein receptors. Here, we introduce a concept of a dynamic artificial receptor that synergically combines molecular recognition with dynamic imine bond formation inside a lipid nanoreactor, inducing a fluorescence response. The designed supramolecular system combines a lipophilic recognition ligand derived from a boronic acid, a fluorescent aldehyde based on push-pull styryl pyridine and a phenol-based catalyst.

Peripheral neurodegenerative diseases induced by irreversible peripheral nerve degeneration (PND), such as diabetic peripheral neuropathy, have a high prevalence worldwide and reduce the quality of life. However, there is no agent effective against the irreversible PND. After peripheral nerve injury, Schwann cells play an important role in regulating PND.

From the Department of Nuclear Medicine, State Key Laboratory of Complex Severe and Rare Diseases, Beijing Key Laboratory of Molecular Targeted Diagnosis and Therapy in Nuclear Medicine, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, Beijing, China.
Purpose: The aim of this study was to investigate the value of 68Ga-NOTA-RM26 (68Ga-RM26), a gastrin-releasing peptide receptor-targeting antagonist labeled with the radionuclide 68Ga, in the diagnosis of high-grade gliomas and in combination with multiregional biopsies using PET/CT.
Patients And Methods: After institutional review board approval and informed consent, a total of 35 patients with suspected glioma lesions were enrolled in this study. All patients underwent 68Ga-RM26 PET/CT scans within 2 weeks before surgery.
