Strain‐Specific Biotransformation of Grape Marc by Lactic Acid Bacteria: Genomic Validation and Gut Microbiota Modulation

open access: yesFood Frontiers, Volume 7, Issue 4, July 2026.
ABSTRACT Grape marc (GM) is a polyphenol‐rich winery byproduct that remains underutilized due to its complex fiber matrix, which limits the bioaccessibility of bound phenolics. While lactic acid fermentation (LAF) can enhance the release of these compounds, the strain‐specific metabolic fate of GM phenolics during digestion and colonic fermentation ...

Biochemical and hematological analysis in acute intermittent porphyria (AIP): a case report

open access: yesAnais da Academia Brasileira de Ciências, 2013
Acute intermittent porphyria is the most common acute porphyria caused by a decrease in hepatic porphobilinogen deaminase activity, resulting in an accumulation of delta-aminolevulinic acid and porphobilinogen.

The “5L” framework of diagnostic reasoning: A stepwise scaffold to support clinician educators

open access: yesJournal of Hospital Medicine, Volume 21, Issue 6, Page 665-669, June 2026.
Abstract Diagnostic reasoning (DR) is a core clinical skill, yet its teaching remains variable. We introduce the “5L” framework as a bedside teaching scaffold that gives educators and learners a shared, stepwise set of prompts for DR during individual encounters. By asking, “What's Lethal? What's Likely? What's Logical? What's Lurking?

Theranostic Advancements in Brain Cancer: Promising Approaches for Emerging Therapy

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Strategies for improving intra‐arterial administration (A) and photodynamic therapy in brain cancer (B). Improving intra‐arterial (IA) administration and photodynamic therapy (PDT) for brain cancer involves enhancing tumor targeting and breaching the blood–brain barrier (BBB). Key strategies include super selective catheterization, using osmotic agents

Porphobilinogen Synthase: A Challenge for the Chemist?

open access: yesCHIMIA, 2001
The initial steps in the biosynthesis of the tetrapyrrolic dyes, called the 'pigments of life', are highly convergent. The formation of porphobilinogen, the pyrrolic precursor of the tetrapyrrolic skeleton, uses ?-aminolevulinate as the starting

Isolation and Characterization of SPOTTED LEAF42 Encoding a Porphobilinogen Deaminase in Rice

open access: yesPlants, 2023
The formation and development of chloroplasts play a vital role in the breeding of high-yield rice (Oryza sativa L.). Porphobilinogen deaminases (PBGDs) act in the early stage of chlorophyll and heme biosynthesis.

Plastid Engineering for Photosynthesis‐Driven Synthesis of Hyaluronic Acid in Tobacco

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2541-2558, April 2026.
ABSTRACT Hyaluronic acid (HA) is a glycosaminoglycan composed of alternating units of N‐acetylglucosamine and glucuronic acid. High moisture retention, viscoelasticity and biocompatibility are unique features that make HA polymers attractive compounds for medical applications and aesthetic purposes.

Structural insights into E. coli porphobilinogen deaminase during synthesis and exit of 1-hydroxymethylbilane.

open access: yesPLoS Computational Biology, 2014
Porphobilinogen deaminase (PBGD) catalyzes the formation of 1-hydroxymethylbilane (HMB), a crucial intermediate in tetrapyrrole biosynthesis, through a step-wise polymerization of four molecules of porphobilinogen (PBG), using a unique dipyrromethane ...
