The bioactive potential of cheese whey peptides from different animal origins (bovine, goat, sheep, buffalo, and camel): A systematic review and meta-analysis.

A systematic review and meta-analysis were conducted to compile information on the bioactive potential of peptides derived from cheese whey from various animal sources, including cattle, sheep, goats, buffaloes, and camels. The systematic search yielded 955 results, with the primary reasons for exclusion being studies that did not utilize cheese whey as a product or did not assess key bioactivities such as antioxidant, antihypertensive, antimicrobial, and anti-aging effects. Ultimately, 36 articles met the inclusion criteria.

Encapsulation of Saccharomyces spp. for Use as Probiotic in Food and Feed: Systematic Review and Meta-analysis.

Probiotics, particularly yeasts from the genus Saccharomyces, are valuable for their health benefits and potential as antibiotic alternatives. To be effective, these microorganisms must withstand harsh environmental conditions, necessitating advanced protective technologies such as encapsulation to maintain probiotic viability during processing, storage, and passage through the digestive system. This review and meta-analysis aims to describe and compare methods and agents used for encapsulating Saccharomyces spp.

Evaluation of the electrolyte status in hyperprolific sows on the farrowing process under different housing conditions.

In order to expand previous knowledge about the farrowing process of hyperprolific sows, the effect of calcium, magnesium and phosphor concentration in the blood and the importance of husbandry were examined. The study was performed in a small educational agriculture institution in Germany comprising 61 sows of a hyperprolific hybrid line (BHZP db.Viktoria).

Characterization of technological and probiotic properties of indigenous spp. from south Brazil.

In this study, we isolated spp. from bovine raw milk and artisanal cheese from southern Brazil, and evaluated their technological and probiotic potential to select new isolates for producing healthy fermented dairy foods with differentiated tastes and flavours. We obtained 48 new lactobacilli isolates, which were isolated from raw milk (38) and cheese (10).

Assessment of selenium bioaccumulation in lactic acid bacteria.

Selenium is an essential micronutrient for living beings, as it helps to maintain the normal physiological functions of the organism. The numerous discoveries involving the importance of this element to the health of human beings have fostered interest in research to develop enriched and functional foods. The present study evaluated the potential for bacterial strains of Enterococcus faecalis (CH121 and CH124), Lactobacillus parabuchneri (ML4), Lactobacillus paracasei (ML13, ML33, CH135, and CH139), and Lactobacillus plantarum (CH131) to bioaccumulate Se in their biomass by adding different concentrations of sodium selenite (30 to 200 mg/L) to the culture medium.

Development of alginate-pectin microparticles with dairy whey using vibration technology: Effects of matrix composition on the protection of Lactobacillus spp. from adverse conditions.

In this study, lactic acid bacteria with probiotic potential, including Lactobacillus plantarum ATCC8014, L. paracasei ML33 and L. pentosus ML82, were encapsulated with whey-alginate-pectin (WAP) or whey permeate-alginate-pectin (PAP) by an extrusion process using vibrational technology, with the resulting microparticles assessed for their resistance to adverse conditions.

Structural organization and mapping of the human mitochondrial glycerol phosphate dehydrogenase-encoding gene and pseudogene.

Mitochondrial glycerol phosphate dehydrogenase (mtGPD) is the rate-limiting enzyme in the glycerol phosphate shuttle, which is thought to play an important role in cells that require an active glycolytic pathway. Abnormalities in mtGPD have been proposed as a potential cause for non-insulin-dependent diabetes mellitus. To facilitate genetic studies, we have isolated genomic clones containing the coding regions of the human mtGPD-encoding gene (GPDM).

The sequence of the rat pyruvate carboxylase-encoding cDNA.

A composite 3945-bp cDNA that encodes rat pyruvate carboxylase (PC) has been constructed from clones isolated from a rat liver cell cDNA library and the nucleotide sequence has been determined. The rat cDNAs open reading frame encodes a protein of 1178 amino acids that is 98.6% identical (99.

Sequence of a cDNA encoding chicken vasoactive intestinal peptide (VIP).

Mammalian pre-pro-vasoactive intestinal peptide (pre-proVIP) gives rise to the neuropeptides vasoactive intestinal peptide (VIP) and peptide histidine isoleucine amide (PHI). The cDNA encoding chicken VIP was cloned and sequenced. The region of chicken pre-proVIP homologous to the mammalian PHI region is not followed by an amidation signal.

The sequence of a human mitochondrial glycerol-3-phosphate dehydrogenase-encoding cDNA.

A 2618-bp cDNA that encodes the human mitochondrial glycerol-3-phosphate dehydrogenase has been isolated from a HeLa cell cDNA library and the nucleotide sequence determined. An open reading frame encodes a protein of 727 amino acids that is 96% similar to the rat protein and, like the rat protein, contains sites homologous to the Ca(2+)-binding sites of calmodulin, as well as FAD- and putative glycerol-phosphate-binding sites.

The cooperative binding of chromosomal protein HMG-14 to nucleosome cores is reduced by single point mutations in the nucleosomal binding domain.

Mutants of human chromosomal protein HMG-14 were generated by site directed mutagenesis and used to study functional domains in this protein. A replacement of serine by cysteine at position 7 did not affect the binding of the protein to nucleosome cores. The sulfhydryl group in the nucleosome-bound protein is accessible to modifying agents suggesting that position 7 in the protein is not in close contact with either the DNA or the histones in the core particles.

Sequence of rat mitochondrial glycerol-3-phosphate dehydrogenase cDNA. Evidence for EF-hand calcium-binding domains.

The FAD-dependent, mitochondrial glycerol-3-phosphate dehydrogenase (EC 1.1.99.

Evolutionarily conserved motifs and protein binding elements in the 5' region of the chromosomal protein HMG-14 gene.

Although the structure of several genes coding for chromosomal proteins HMG-14 and HMG-17 has been determined, the mechanisms regulating the expression of these genes has not yet been examined. Toward this goal, we have cloned and sequenced a fragment containing the first three exons and 956 bp upstream from the start of translation of the functional mouse HMG-14 gene. Comparison of this sequence to the known sequence of the human HMG-14 gene revealed the presence of five distinct blocks of high sequence identity flanking the start of transcription and the CAAT box.

A general approach to testing multifaceted personality constructs.

Some personality characteristics are composed of multiple, distinct subcomponents (e.g., Type A, hardiness, attributional style, self-monitoring).

Recombinant human chromosomal proteins HMG-14 and HMG-17.

Vectors for expressing human chromosomal proteins HMG-14 and HMG-17 in bacterial cultures under the control of the temperature-inducible lambda PL promoter have been constructed. The open reading frames of the cDNAs have been amplified by the polymerase chain reaction (PCR), utilizing amplimers containing desired restriction sites, thereby facilitating precise location of the initiation codon downstream from a ribosomal binding site. Expression of the recombinant proteins does not significantly affect bacterial growth.

Alternative processing of mRNAs encoding mammalian chromosomal high-mobility-group proteins HMG-I and HMG-Y.

The high-mobility-group protein HMG-I is a well-characterized nonhistone chromosomal protein that is preferentially expressed in rapidly dividing cells, binds to A. T-rich regions of DNA in vitro, and has been localized to particular regions of mammalian metaphase chromosomes. We isolated eight cDNA clones encoding HMG-I and its isoform HMG-Y from a human Raji cell cDNA library and detected blocks of nucleotide sequence rearrangements in the 5'-untranslated regions of these clones.

Complete murine cDNA sequence, genomic structure, and tissue expression of the high mobility group protein HMG-I(Y).

A cDNA coding for the non-histone chromosomal protein HMG-I, or its isoform HMG-Y, was isolated from a murine Friend cell library using synthetic oligonucleotide hybridization probes. Sequence analysis showed that the 1670-base pair full length cDNA insert consists of a 201-base pair, G/C-rich (74%), 5'-untranslated region, a 288-base pair amino acid coding sequence, and an unusually long 1182-base pair 3'-untranslated region. The deduced 96-residue amino acid coding sequence of the murine HMG-I(Y) cDNA is very similar to the reported amino acid sequence of human HMG-I, except that it lacks 11 internal amino acids reported in the human protein.

A conformational study of the sequence specific binding of HMG-I (Y) with the bovine interleukin-2 cDNA.

The DNA sequence specific interaction of the high mobility group non-histone protein HMG-I (Y) with the 3' untranslated region of the bovine interleukin-2 cDNA has been studied. Circular dichroism and thermal denaturation studies suggest that HMG-I (Y) alters the conformational state and increases the thermal stability of the DNA. Additionally, amino acid sequence analysis suggests that the previously identified non-histone protein HMG-Y is an isoform of HMG-I.

Posttranscriptional gene regulation and specific binding of the nonhistone protein HMG-I by the 3' untranslated region of bovine interleukin 2 cDNA.

The 3' untranslated tail region (3'-UTR) of the cDNA of bovine interleukin 2 (bIL-2) acts as a lymphoid cell-specific gene regulatory element in vivo when ligated to the 3' end of the "marker" bacterial gene coding for chloramphenicol acetyltransferase (CAT) and the hybrid fusion gene is introduced into bovine lymphoid cells by transfection. Evidence is also presented that the 3'-UTR with its conserved (TATT)n motif probably has multiple functions in lymphoid cells operating both at the chromosomal level, where the sequence may be involved in the specific binding of the nonhistone chromatin high mobility group protein HMG-I, and at the RNA level, where the conserved sequence is involved in selective posttranscriptional mRNA degradation by a lymphocyte-specific nuclease(s). These results suggest a complex in vivo role for the 3'-UTR of bIL-2 cDNA and the conserved (TATT)n sequences found within it.
