Chlorophyllase from Reveals an Emerging Model for Controlling Chlorophyll Hydrolysis.

Chlorophyll (Chl) is one of Nature's most complex pigments to biosynthesize and derivatize. This pigment is vital for survival and also paradoxically toxic if overproduced or released from a protective protein scaffold. Therefore, along with the mass production of Chl, organisms also invest in mechanisms to control its degradation and recycling.

Assessing the role of mitonuclear interactions on mitochondrial function and organismal fitness in natural populations.

Mitochondrial function depends on the effective interactions between proteins and RNA encoded by the mitochondrial and nuclear genomes. Evidence suggests that both genomes respond to thermal selection and promote adaptation. However, the contribution of their epistatic interactions to life history phenotypes in the wild remains elusive.

What Clinicians Think About When They Think About Sepsis: Results From a Survey Across the University of Maryland Medical System.

Importance: Sepsis, a leading cause of death in the hospital, is a heterogeneous syndrome without a defined or specific set of symptoms.

Objectives: We conducted a survey of clinicians in practice to understand which clinical findings they tend to associate with sepsis.

Design, Setting, And Participants: A survey was distributed to physicians and advanced practice providers across a multihospital health system during April 2022 and May 2022 querying likelihood of suspecting sepsis and initiating sepsis care in response to various normal and abnormal clinical findings.

Protocol for measuring anti-fentanyl antibodies in mouse serum by enzyme-linked immunosorbent assay.

Enzyme-linked immunosorbent assay (ELISA) offers an effective, inexpensive, and reliable approach for the analysis of humoral immune responses. Here, we describe a protocol for measuring anti-fentanyl antibodies generated by the immunization of mice with novel opioid vaccine candidates. We describe steps for coating BSA-fentanyl antigen and standard wells.

The BNT162b2 mRNA vaccine demonstrates reduced age-associated T1 support and .

mRNA vaccines demonstrate impaired immunogenicity and durability in vulnerable older populations. We hypothesized that human modeling and proteomics could elucidate age-specific mRNA vaccine actions. BNT162b2-stimulation changed the plasma proteome of blood samples from young (18-50Y) and older adult (≥60Y) participants, assessed by mass spectrometry, proximity extension assay, and multiplex.
