Assessing Arsenic Species in Foods Using Regularized Linear Regression of the Arsenic K-edge X-ray Absorption Near Edge Structure
J Anal At Spectrom. 2022;37(6):10.1039/d1ja00445j. doi: 10.1039/d1ja00445j.ABSTRACTThe toxicity and bioavailability of arsenic is heavily dependent on its speciation. Therefore, robust and accurate methods are needed to determine arsenic speciation profiles for materials related to public health initiatives, such as food safety. Here, X-ray spectroscopies are attractive candidates as they provide in situ, nondestructive analyses of solid samples without perturbation to the arsenic species therein.

1123 Exploring potential anti-melanoma compounds in brown algae sargassum crassifolium lipophilic extract
Algae are found abundantly in tropical countries and have various invaluable metabolites which are not fully explored for their skin health benefits. Therefore in this study, we evaluated the anti-melanoma activity of the lipophilic extract from a under-utilized brown algae widely found on the Indonesian coast, Sargassum crassifolium. Lipophilic extract of S. crassifolium was obtained with chloroform: methanol extraction, and the anti-oxidant activity was observed by the in-vitro DPPH method. Moreover, we also identified the metabolites in S. (Source: Journal of Investigative Dermatology)

Establishment of specific age-related macular degeneration relevant gene expression panels using porcine retinal pigment epithelium for assessing fucoidan bioactivity
CONCLUSION: Three specific gene expression panels for porcine RPE that map genes for three of the major pathological factors of AMD, inflammation, oxidative stress, and angiogenesis, were established. Further, we demonstrated that fucoidans can reduce stress related gene activation in all of these three major pathogenic pathways. This study is another indication that fucoidans can act on different pathomechanisms of AMD simultaneously, which provides further evidence for fucoidans as a possible drug for treatment and prevention of AMD.PMID:37037364 | DOI:10.1016/j.exer.2023.109469 (Source: Cell Research)

Probiotic bifidobacterium and a new generation postbiotic: alginic acid
According to International Scientific Association for Probiotics and Prebiotics (ISAPP) consensus (2019),Postbiotics are defined as a preparation of inanimate microorganisms and/or their components that confers a health benefit on the host. Postbiotic Alginic acid, also called algin, is a naturally occurring, edible exopolysaccharide found in brown algae. Alginic acid and its Na/Ca salt form of Alginate show the capability in water-binding, water-retention water, and immense swelling and gelation, which could act as a protective barrier via promoting biofilm formation on the bacterial cell surfaces.
