RNA endonucleases are the rate-limiting initiator of decay for many bacterial mRNAs. However, the positions of cleavage and their sequence determinants remain elusive even for the well-studied Bacillus subtilis. Here we present two complementary approaches-transcriptome-wide mapping of endoribonucleolytic activity and deep mutational scanning of RNA cleavage sites-that reveal distinct rules governing the specificity among B.

Inactivation of CaV1 and CaV2 channels.

J Gen Physiol

March 2025

Department of Physiology, University of Maryland School of Medicine, Baltimore, MD, USA.

Voltage-gated Ca2+ channels (VGCCs) are highly expressed throughout numerous biological systems and play critical roles in synaptic transmission, cardiac excitation, and muscle contraction. To perform these various functions, VGCCs are highly regulated. Inactivation comprises a critical mechanism controlling the entry of Ca2+ through these channels and constitutes an important means to regulate cellular excitability, shape action potentials, control intracellular Ca2+ levels, and contribute to long-term potentiation and depression.

Selective Neurectomy with Regenerative Peripheral Nerve Interface Surgery for Facial Synkinesis.

Facial Plast Surg Aesthet Med

January 2025

Division of Facial Plastic and Reconstructive Surgery, Department of Otolaryngology-Head & Neck Surgery, University of Michigan, Ann Arbor, Michigan, USA.

Selective neurectomy (SN) typically leaves cut nerve endings to be either free-floating or buried in facial muscles. Regenerative peripheral nerve interfaces (RPNIs) use autologous skeletal muscle grafts to provide a nonfacial muscle target for reinnervation. To evaluate the effectiveness of RPNI surgery with SN for improving postoperative facial function through botulinum toxin use and facial movement metrics.

Regional infusion centers (RICs) played an integral role in treating high-risk patients with COVID-19, with mild to moderate symptoms, who did not need acute hospitalization, with monoclonal antibodies. While any medical provider could place a RIC referral, it was recognized that many people face challenges with accessing care. A dedicated medical team was created to provide telemedical evaluation of patients and place appropriate referrals to RICs.

Forward genetic screens of mutant populations are fundamental for functional genomics studies. However, isolating independent mutant alleles to molecularly identify causal genes is challenging in species recalcitrant to genetic manipulation. Here, we demonstrate that classic seed EMS mutagenesis coupled with genome sequencing can overcome this limitation in sorghum.

Effective documentation and coding in health care are crucial for patient care, safety, workflow improvement and accurate billing. This quality improvement study aimed to enhance History and Physical (H&P) note documentation and charge capture processes to integrate coding and billing aspects, capture authentic work, preserve the H&P's integrity and align H&P-related revenue with actual performance. A multidisciplinary team, including divisional leadership and specialists in documentation improvement, electronic health records, lean/six sigma methodology, a nocturnist and a senior-level physician coding auditor, initiated a quality improvement project.

Plant mitochondrial genomes (mitogenomes) experience remarkable levels of horizontal gene transfer (HGT), including the recent discovery that orchids anciently acquired DNA from fungal mitogenomes. Thus far, however, there is no evidence that any of the genes from this interkingdom HGT are functional in orchid mitogenomes. Here, we applied a specialized sequencing approach to the orchid Corallorhiza maculata and found that some fungal-derived tRNA genes in the transferred region are transcribed, post-transcriptionally modified, and aminoacylated.

Introduction: Sotalol is a beta-adrenoceptor blocking drug with unique physical and pharmacologic properties. Unlike most beta-adrenoceptor blocking drugs, sotalol is amenable to extracorporeal removal and causes QT interval prolongation and ventricular dysrhythmias. These properties have implications for treating sotalol poisoning.

Efficacy and safety of risankizumab for the treatment of patients with plaque type psoriasis.

Department of Dermatology, College of Medicine, National Taiwan University Hospital, National Taiwan University, Taipei, Taiwan (ROC) -

Risankizumab (Skyrizi, Abbvie, North Chicago, IL, USA) is a humanized immunoglobulin (Ig) G1 monoclonal antibody targeting the p19 subunit of IL-23, thereby inhibiting IL-23-dependent releasing of proinflammatory cytokines in plaque psoriasis. Risankizumab is licensed is most countries for the treatment of patients with moderate-to-severe plaque psoriasis, and in Japan for generalized pustular psoriasis, erythrodermic psoriasis and palmoplantar pustulosis. Risankizumab showed higher efficacy and favorable safety profiles in patients with moderate-to-severe plaque psoriasis, compared with adalimumab, secukinumab and ustekinumab in several randomized controlled phase 3 pivotal studies and among real-life data in large retrospective studies.

To study its pathogenesis, we developed a human challenge model in which we infect the skin on the upper arm of human volunteers with to the pustular stage of disease. The model has been used to define lesional architecture, describe the immune infiltrate into the infected sites using flow cytometry, and explore the molecular basis of the immune response using bulk RNA-seq.

Unlabelled: Mutations affecting flagellin (FliC) have been shown to be hypervirulent in animal models and display increased toxin production and alterations in central metabolism. The regulation of flagellin levels in bacteria is governed by a tripartite regulatory network involving , , and , which creates a feedback system to regulate flagella production. Through genomic analysis of clade 5 strains (non-motile), we identified they have jettisoned many of the genes required for flagellum biosynthesis yet retain the major flagellin gene and regulatory gene .

Unlabelled: Many animals contain a species-rich and diverse gut microbiota that likely contributes to several host-supportive services that include diet processing and nutrient provisioning. Loss of microbiome taxa and their associated metabolic functions as result of perturbations may result in loss of microbiome-level services and reduction of metabolic capacity. If metabolic functions are shared by multiple taxa (i.

Coronaviruses (CoV) emerge suddenly from animal reservoirs to cause novel diseases in new hosts. Discovered in 2012, the Middle East respiratory syndrome coronavirus (MERS-CoV) is endemic in camels in the Middle East and is continually causing local outbreaks and epidemics. While all three newly emerging human CoVs from the past 20 years (SARS-CoV, SARS-CoV-2, and MERS-CoV) cause respiratory disease, each CoV has unique host interactions that drive differential pathogeneses.

The goal of this study was to characterize the microbial profile of two different fresh pork cuts, bootjack (BJ) trim and tenderloin (TL), through a 16S rRNA sequencing workflow developed specifically for investigating low-biomass fresh meat within a commercial production schedule. Additionally, this study aimed to determine a baseline prevalence and enumeration profile across these two fresh pork cuts. Results showed that microbiome diversity was different between the BJ and TL, and also differed significantly by processing date.

The evolution of oxygenic photosynthesis in the Cyanobacteria was one of the most transformative events in Earth history, eventually leading to the oxygenation of Earth's atmosphere. However, it is difficult to understand how the earliest Cyanobacteria functioned or evolved on early Earth in part because we do not understand their ecology, including the environments in which they lived. Here, we use a cutting-edge bioinformatics tool to survey nearly 500,000 metagenomes for relatives of the taxa that likely bookended the evolution of oxygenic photosynthesis to identify the modern environments in which these organisms live.
