Potentiometric Determination of the Stability Constants of 2-, 3- and 4-Hydroxybutyrato Complexes of Cobalt(II), Nickel(II), Cadmium(II) and Lead(II) [PDF]

open access: yes, 1978
The stability constants of the title complexes were determined potentiometrically using a quinhydrone electrode at (298.2 ± 0.1) K in buffer solutions of ionic strength 2 mol dm-3 adjusted by addition of NaC104• The numerical values of stability ...

Biopolymer‐Coated Paper Composites for Sustainable Packaging

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Conventional plastic packaging, though dominant in food and flexible applications, poses serious environmental concerns due to its persistence and limited recyclability. To address this challenge, this study develops bio‐based coated paper composites as sustainable alternatives. Paper, while biodegradable, lacks adequate barrier properties. To

Growth Hormone Promotes Lipolysis and Impairs Insulin Sensitivity by Activating the ERK/HSL Signaling Pathway in Bovine Adipocytes

open access: yesAnimal Research and One Health, EarlyView.
This study was to evaluate the role of GH in lipolysis and insulin sensitivity in bovine adipocytes and clarify the underlying mechanism. Our findings demonstrate that GH activates ERK/HSL signaling pathway, promotes lipolysis, and impairs insulin sensitivity in bovine adipocytes.

Compensation Response to Hepatic Gluconeogenesis via β‐Hydroxybutyrylation of FBP1 and PCK1 in Dairy Cows

open access: yesAnimal Research and One Health, EarlyView.
(1) Kbhb modification of FBP1 and PCK1 is involved in regulation of the gluconeogenesis pathway. (2) Kbhb of FBP1 and PCK1 is catalyzed by p300 and removed by HDACs. (3) BHB induced an increase in the enzymatic activity of FBP1 and PCK1 through Kbhb modification at the K43 site of FBP1 and the K191 site of PCK1.

Synthesis Of Cyclic And Linear Poly(hydroxybutyrates) By Ring-opening Polymerization Of β-Butyrolactone With Amido-Oxazolinate Zinc Catalysts [PDF]

open access: yes, 2018
A series of amido-oxazolinate zinc complexes have been employed for the ring opening polymerization of β-butyrolactone (BBL). Experimental results show that these complexes efficiently catalyze the reactions, yielding cyclic poly(hydroxybutyrate)s (PHBs)

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

open access: yesAnimal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Transgenic expression of glucose dehydrogenase in Azotobacter vinelandii enhances mineral phosphate solubilization and growth of sorghum seedlings [PDF]

open access: yes, 2009
The enzyme quinoprotein glucose dehydrogenase (GDH) catalyses the oxidation of glucose to gluconic acid by direct oxidation in the periplasmic space of several Gram-negative bacteria. Acidification of the external environment with the release of gluconic
