Ammonia adducts of chloramphenicol and chloramphenicol palmitate.

Chemical and Pharmaceutical Bulletin, 1977
Chloramphenicol and chloramphenicol palmitate were found to form adducts with ammonia. Both ammonia adducts are so unstable at room temperature that ammonia free antibiotics are easily recovered by rapid elimination of ammonia. Particle size was reduced for chloramphenicol palmitate by repeating sorption and subsequent desorption of ammonia.

Genomic epidemiology and lineage‐specific risk stratification of tet(X4)‐mediated tigecycline resistance along the pork production chain: A One Health perspective

iMetaOmics, EarlyView.
Genome surveillance across a swine‐associated One Health continuum in China shows that slaughterhouses act as major enrichment nodes for tet(X4)‐mediated tigecycline resistance, driven by putative clonal transmission and stable plasmid backbones. Integrating global datasets enables lineage‐specific risk stratification, highlighting key control points ...

Reconceptualizing Aplastic Anemia—Seed, Worm, Soil

Journal of Clinical Laboratory Analysis, EarlyView.
Aplastic anemia (AA) encompasses a group of hematological syndromes often misdiagnosed, resulting in a decrease in the overall blood cell count and representing a form of bone marrow failure. We reinterpret AA based on the “seed, worm, and soil” doctrine.

Detecting Antibiotic Resistance in Strains of Selected Gram‐Negative Bacterial Species Using Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
Raman spectroscopy successfully identified antibiotic‐resistant Gram‐negative strains. Resistant strains of four bacterial species were discriminated from sensitive ones with 99.1% accuracy using PLS regression. The method allows for rapid, label‐free detection of antibiotic resistance.

Optimizing germination and cultivation of edible halophytes using effluents from an IMTA system

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Halophytes offer nature‐based solutions to food insecurity and soil degradation, while their integration into integrated multi‐trophic aquaculture (IMTA) systems promotes circular economy practices. This study aimed to optimize the germination and cultivation of edible halophytic species, namely Limbarda crithmoides, Suaeda vera and

Direct interaction between MreB and the RodA‐PBP2 complex organizes lateral cell wall synthesis in Escherichia coli

mLife, EarlyView.
Abstract The elongasome, or the Rod complex, orchestrates lateral peptidoglycan (PG) synthesis in many rod‐shaped bacteria. It consists of the actin‐like protein MreB, the PG synthase RodA‐PBP2 complex, as well as MreCD and RodZ. Although the loss or disruption of any elongasome component results in a loss of rod shape, previous studies found that a ...

The X‐Ray Crystal Structure of BorF, the Flavin Reductase Subunit of a Two‐Component Flavin‐Dependent Tryptophan Halogenase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT BorF is a short‐chain flavin reductase from a desert soil bacterium that uses NADH to reduce FAD to FADH2, which is used by the tryptophan‐6‐halogenase BorH to chlorinate tryptophan in the biosynthetic pathway of borregomycin A. The X‐ray crystal structure of BorF bound to FAD was solved to 2.37 Å by molecular replacement.

Structural Insights Into the Function of Leishmania major Adenylosuccinate Lyase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT One of several intriguing aspects of kinetoplastid biochemistry is the complete dependence on host purines and purine recycling due to the lack of a de novo purine biosynthesis pathway. Adenylosuccinate lyase (ASL, EC 4.3.2.2) is a key enzyme in the purine synthesis pathway responsible for the conversion of adenylosuccinate into adenosine ...
