Bovine digital dermatitis (BDD) is the most prevalent infectious cause of lameness in cattle. Because Treponema infection is a major etiology of BDD, the most common treatment of BDD is an antibiotic. Nonetheless, dairy cows require a withdrawal period after antibiotic treatment before their milk can be marketed. To address the problem, in this study, we tested whether 3 nonantibiotic agents (u...

Macroscopically homogeneous and inhomogeneous calcium alginate gels are formed via internal or external addition of various amounts of calcium to an alginate solution. The externally formed gels contain parallel aligned capillary structures. The mechanical and mass transport properties and the microstructure of the differently set gels were characterized by rheological measurements, fluorescenc...

Ammonium sulfate fractionated proteins of bitter gourd (Momordica charantia) were precipitated using jack bean extract as a source of concanavalin A. Concanavalin A-bitter gourd peroxidase retained nearly 86% original activity. This complex was entrapped into calcium alginate-pectin gel. Entrapped concanavalin A-peroxidase complex retained 51% original activity. Soluble and immobilized peroxida...

Wet spinning was used to manufacture fibrous alginate hydrogel wound dressings. Samples manufactured using varied operating parameters (decreased air pressure and calcium concentration or increased nozzle diameter and alginate concentration) were compared with the control samples. The changes in the fiber size, Young's modulus, swelling ratio, fetal bovine serum (BSA) release efficacy, water va...

Abstract The present study revealed for the first time removal of hexavalent chromium Cr(VI) with a high efficiency using an eco-friendly composite beads alginate green alga Ulva fasciata compared to calcium beads. This conclusion was reached in this from comparison by well-known biosorbent material, (CA) studied alginate/ (CA/UF) biocomposite characterization prepared achieved several techniqu...

Mixed gelatin-alginate gels are widely studied as encapsulating matrices. However, the dissolution of gelatin at mild temperatures (close to body temperature) imparts low stability for these systems, particularly as delivery matrices. In this context, collagen fiber arises as an alternative due to its water binding properties. Thus, the main objective of this work was to evaluate the effect of ...

The aim of the study was to evaluate the effect of composition and technological processing on pharmaceutical availability of active substance as well as on the properties of porous gelatin-alginate matrices. The active substance carrier included glycerol or peanut oil apart from gelatin and sodium alginate, and some matrices were additionally modified with calcium lactate. The obtained matrice...

This paper reports a new approach for constructing blood vessel-like tissues using microfluidic devices made of calcium-containing agarose hydrogel. Sodium alginate (NaA) solutions with different cell types at high densities were introduced stepwise into the hydrogel microchannel, to deposit cell-containing multiple Ca-alginate hydrogel layers on the channel surface with the help of Ca 2+ ions ...

Phospholipase A1 (PLA1) immobilized in calcium alginate can effectively overcome the mass transfer resistance at the lipid-water interface making more room for the enzyme to separate itself from the products of reaction and to bind with the next available molecule at the interface. The reaction of an immobilized PLA1 hydrolase from Thermomyces lanuginosus was comparatively faster than of its fr...
