Genetic characterization of a brangus-ibage cattle population: biochemical polymorphisms and reproductive efficiency Caracterização genética de uma população de bovinos brangus-ibagé: polimorfismos bioquímicos e eficiência reprodutiva

open access: yesCiência Rural, 2000
Biochemical techniques were used to investigate the genetic variability in a Brangus-Ibage population by determining allele frequencies of 18 blood protein systems: Hemogloin beta-Chain (Hb), Albumin (Alb), Amylase (Am), Transferrin (Tf), Carbonic ...

INHERITANCE OF DIAPHORASE AND GLUCOSE-6-PHOSPHATE ISOMERASE IN EUSTOMA GRANDIFLORUM [PDF]

open access: yesHortScience, 1992
Segregating progenies from controlled pollinations of Eustoma grandiflorum Griseb. were investigated to determine the inheritance of diaphorase (DIA) and glucoses-phosphate isomerase (GPI) isozymes. Phenotypic data supported the hypotheses that DIA1 is tetrameric and is controlled by a single locus with two alleles (Dia1-1 and Dia1-2) and that GPI1 is ...

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.

One-pot Enzymatic Synthesis of Deoxy-thymidine-diphosphate (TDP)-2-deoxy-∝-d-glucose Using Phosphomannomutase

open access: yes, 2010
Production of deoxy-thymidine-diphosphate (TDP)-sugars as substrates of glycosyltransferases, has been one of main hurdles for combinatorial antibiotic biosynthesis, which combines sugar moiety with aglycon of various antibiotics. Here, we report the one-

Modulation of Tau Protein Neurotoxic Hallmarks by Novel σ1R Agonists/HDAC Inhibitor Dual‐Acting Compounds

open access: yesChemMedChem, Volume 21, Issue 5, 13 March 2026.
This study explores the development of dual‐acting compounds combining σ1R agonists and histone deacetylase inhibitors (HDACi). Key findings include compound 2d and 3a's high affinity for σ1R and favorable pharmacokinetic profile and an in vivo determined σ1R agonist profile by reversing the effect of the σ1R antagonist BD‐1063.

Catalytic Amyloids: Turning Fibrils Into Biocatalysts

open access: yesChemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as

Systematic Metabolic Engineering and Model‐Guided Optimization for High‐Level Production of L‐Theanine from Xylose in Escherichia coli

open access: yesAdvanced Science, Volume 13, Issue 17, 23 March 2026.
This study is pioneering in constructing the shortest known synthetic pathway for L‐theanine production from xylose within E coli. Through comprehensive metabolic engineering strategies, our engineered strain achieved the highest reported L‐theanine titer from xylose, with a titer of 95.42 g/L, and a yield of 0.55 g/g.
