Summary: The study found that xanthan gum and gum Arabic had different effects on the distribution of gas bubbles in wet foams, with xanthan gum affecting the foam's viscous nature and gum Arabic increasing its plasticity. The analysis was conducted through physiochemical and rheological tests, providing insights into the properties of foams created with these additives.

Summary: Overconsumption of fat-rich foods has caused a significant increase in chronic diseases in humans. This study used egg white protein microparticle, xanthan gum, and gum arabic as additives to develop a low-fat mayonnaise. The results showed that xanthan gum and gum arabic had a synergistic effect on modifying the viscosity and recovery of the low-fat mayonnaise. Xanthan gum effectively increased the viscosity through electrostatic binding with the egg white protein microparticle, and the combination with gum arabic improved recovery by intervening in intermolecular interactions.

Summary: In this study, rough emerald single crystals and rough emeralds in the host rock from the ruins of Alexandria and from Mount Zabargad in Egypt were investigated. Non-destructive spectroscopic and chemical methods were used to characterize the samples. The results showed that Egyptian emeralds contain H2O molecules and relatively high concentrations of alkali ions, and are colored by chromium and iron. Inclusions and associated minerals were also identified in these historic emeralds from Egypt. This study contributes to the characterization of emeralds of archaeological significance.

Summary: The aim of this study was to investigate the effect of gum arabic coating on the quality characteristics of table eggs during storage. The results showed that coating the eggs with 10% gum arabic solution reduced weight loss and albumen pH, and increased specific gravity. There were no significant differences in shell strength, Haugh unit or yolk index between coated and control eggs. Eggs stored at 4 degrees C had better quality characteristics compared to those stored at 25 degrees C.

Summary: The study showed that replacing egg yolk with different concentrations of gum Arabic in Tris extender improved the quality and fertility of cryopreserved buck sperm. Specifically, Tris extender containing 9% gum Arabic demonstrated the highest total motile sperm and pregnancy rate. This suggests that gum Arabic can be a viable alternative to egg yolk in cryopreservation of buck sperm.

Summary: Alzheimer's disease is a incurable disease and the main cause of age-related dementia worldwide. Research has shown promising results for the treatment of AD with lithium, although the underlying mechanism is still unclear. The interactions between A beta peptides and Li+ ions have not been well investigated in relation to AD pathology.

Summary: ALS, Alzheimer's disease, Parkinson's disease and other neurodegenerative disorders have a significant impact on patients, caregivers, and society due to the aggregation of proteins in nerve cells. TDP-43 seems to play a specific role in ALS pathogenesis, and further research is needed on the role of metals in TDP-43 aggregation.

Summary: Cell-penetrating peptides (CPPs) derived from a prion protein (PrP) have exhibited disease-modifying properties against prion proteins and the amyloid-beta (A beta) peptide in Alzheimer's disease. These CPPs can interact with PrP/A beta and redirect their aggregation pathways, resulting in reduced cell-toxicity.

Summary: Mercury intoxication has more severe effects on individuals with the APOE-e4 gene, possibly due to the ApoE4 protein's poorer ability to clear heavy metals compared to the ApoE2 and ApoE3 variants. In vitro experiments showed that Hg(I) ions have weak interactions with all ApoE variants and induce no significant structural changes. Hg(II) ions, on the other hand, bind strongly to all three ApoE isoforms and cause alterations in their superhelicity, with the most pronounced effects observed in the ApoE4 protein.

Summary: Cell-penetrating peptides (CPPs) are promising transfection agents for delivering compounds into living cells. The properties of the resulting CPP particles in an aqueous solution depend on the solvent used for dissolving the CPP. Using different methods, such as dynamic light scattering and microscopy, it was found that CPPs dissolved in organic solvents form uniform particles, while those dissolved in water tend to form aggregates and micelles.

Summary: Copper is an essential biometal that serves as a cofactor in many proteins. ATCUN motifs, small peptide sequences, can bind to copper ions. These motifs are present in various proteins and peptides and play a role in copper metabolism. The binding affinity of ATCUN peptides can vary greatly. In this study, it was demonstrated that ATCUN motifs have similar affinity to HSA for binding copper ions in blood and cerebrospinal fluid.

Summary: This study reports the technical examination of an iron draw-plate found in Uppsala, Sweden. Analysis using X-ray and scanning electron microscopy revealed the presence of silver particles in the plate's holes, indicating the drawing of silver wire. The discovery of this draw-plate increases our understanding of Vendel Period jewelry production and social organization.

Summary: Chemical treatment of skeletal remains can reduce overall DNA quality and quantity but has no significant impact on stable isotope ratio analysis. Examination of treated and untreated human remains through histological and stable isotope analysis reveals that treated remains exhibit better preservation compared to untreated remains. Stable isotope ratio analysis is viable for both treated and untreated remains, regardless of their origin.

Summary: This paper presents the outcomes of a microcontextual geoarchaeological study conducted on earthen dwellings from the Early Iron Age village of Cerro de San Vicente. The study employed soil micromorphology, lipid biomarker analysis, XRD, and XRF analyses to investigate various aspects of the dwellings, including construction materials, site formation processes, and daily life practices. The results have shed light on the construction layers, floor use, maintenance, repaving, periods of abandonment and decay, and the presence of lipid biomarkers associated with dwelling functionality. The study significantly contributes to our understanding of ancient construction practices and the utilization of domestic spaces during the Early Iron Age.
