Four calcium compounds containing uronic acids (D(+)-galacturonic and D(+)-glucuronic) in L:M ratio = 2 and 3 were isolated by applying novel (except for one complex) synthetic procedures. The compounds were characterized by elemental analysis, spectroscopic methods (diffuse reflectance and absorption UV-visible, IR, FIR), mass spectrometry, fast atom bombardment (FAB), thermal decomposition, thermogravimetry/derivative thermogravimetry (TG/DTG) data and differential scanning calorimetric studies (DSC). Two modes of water binding in the complexes, i.e., hydration and coordination-like, were established. Computer-aided analysis has shown that further investigations are needed in order to determine the applicability of calcium uronates as calcium carriers.

Purpose: Removal of the current calcium alginate packing materials to the middle meatus in endoscopic sinus surgery (ESS) is usually accompanied by discomfort or pain owing to the hard and brittle nature of these materials. Plus moist HS-W is a new calcium alginate packing material released in 2022 developed to overcome this issue by changing the uronic acid component. We aimed to compare the discomfort/pain during the removal of Plus moist HS-W with Kaltostat, as well as their suitability as packing materials in ESS.

The pigments consumed in grazing give the milk from dual-purpose cows raised in tropical conditions a yellowish color, affecting the quality and price of the milk. This study aimed to develop an economical method with supplementary pectin to antagonize the availability of carotenes by designing microparticles with shellac and palm oil as a viable alternative to protect pectin degradation against rumen microbes. Three preparations of microparticles based on citrus pectin were synthesized: unprotected (PnP), protected with palm oil (PwP), and protected with palm oil and shellac (PwPL) microparticles.

Background: Kenaf seeds are underutilized kenaf plant by-products, containing essential nutrients including dietary fiber (DF), which can be potentially utilized as food ingredients. The present study aimed to evaluate the physicochemical characteristics of kenaf seed fiber fractions extracted from kenaf seed.
Results: Defatted kenaf seed powder yielded four DF fractions: alkali-soluble hemicellulose (146.

Background: Salpingitis is one of the common diseases in laying hen production, which greatly decreases the economic outcome of laying hen farming. Lactiplantibacillus plantarum was effective in preventing local or systemic inflammation, however rare studies were reported on its prevention against salpingitis. This study aimed to investigate the preventive molecular regulatory network of microencapsulated Lactiplantibacillus plantarum (MLP) against salpingitis through multi-omics analysis, including microbiome, transcriptome and metabolome analyses.
