Turkish Journal of Biology

Background/aim: Neurodegenerative diseases such as Alzheimer’s, Parkinson’s, Huntington’s, and ALS are characterized by a progressive loss of nerve cells, for which no definitive cure currently exists. These conditions share common pathological mechanisms, including chronic neuroinflammation, oxidative stress, protein aggregation, and mitochondrial dysfunction. Flavonoids and other plant-derived phenolic compounds have recently attracted attention for the treatment of such conditions due to their antiinflammatory and antioxidant properties. This review explores the neuroprotective mechanisms of flavonoids and evaluates their potential for the prevention and treatment of neurodegenerative diseases.

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Biological nitrogen fixation (BNF) is the primary input of new reactive nitrogen to natural terrestrial ecosystems. However, this flux is poorly constrained due to its unclear drivers and associated control mechanisms. Here, we extend the existing theory of nitrogen (N) isotope mass balance to estimate BNF rates and then use a Bayesian approach to constrain the BNF rates in natural terrestrial ecosystems by using measurements of natural N-isotope ratios (δ¹⁵N) in plants (δ_P) and soil (δ_S). Together with pairwise δ_P and δ_S measurements from 18 forest sites covering diverse climates and thousands …

Food and Machinery

[Objective] To investigate the protective effect of Haematococcus pluvialis (H.pluvialis) powder on lipopolysaccharide (LPS)-induced oral epithelial damage. [Methods] The effects of different doses of H.pluvialis on the viability of human oral keratinocytes (HOKs) were assessed. In LPS-induced HOKs, changes in the tight junction-associated proteins ZO-1 and Occludin, mitochondrial morphology, reactive oxygen species (ROS), mitochondrial membrane potential (MMP), mitochondrial superoxide (MitoSOX), and mitochondrial permeability transition pore (MPTP) were evaluated. [Results] Compared with the LPS model group, high-dose H.pluvialis significantly upregulated the expression levels of Occludin and ZO-1 to 151.56% and 170.52%, respectively (P < 0.05), and promoted their membrane localization. In addition, H.pluvialis markedly improved LPS-induced excessive ROS and MitoSOX production, the reduction in MMP, and the increase in MPTP in HOKs. [Conclusion] H.pluvialis may alleviate LPS-induced barrier damage in HOKs by improving mitochondrial dysfunction and reducing oxidative stress, suggesting its potential as a functional food for oral mucosal barrier repair.

Effect Of Ultrasonic Thawing On The Quality And Protein Oxidation Of Litopenaeus Vannamei, Peng Panpan

Food and Machinery

[Objective] To improve the texture quality of frozen Litopenaeus vannamei. [Methods] Using Litopenaeus vannamei as the research object, the study systematically evaluates the effects of ultrasonic thawing (300, 400, 500 W) on the texture properties, thawing loss, cooking loss, TVB-N, TBARS values, protein oxidation (content of sulphydryl and carbonyl groups), amino acid release, pH value, and sensory evaluation of frozen shrimp. [Results] Ultrasonic thawing significantly increases the elasticity, hardness, and recovery of the frozen shrimp (P<0.05), with the 400 and 500 W ultrasonic groups showing significantly higher hardness and elasticity than the 300 W group. Ultrasonic thawing significantly reduces thawing loss, cooking loss, and TVB-N content in the frozen shrimp (P<0.05), with the 500 W ultrasonic group showing the most significant reduction. Amino acid analysis reveals that ultrasonic thawing significantly increases the total amino acid (TAA) content and the proportion of essential amino acids (EAA), with the release of essential amino acids such as leucine and glutamic acid being highest in the 300 and 400 W ultrasonic groups. The protein oxidation analysis shows that the sulphydryl content in the ultrasonic-thawed group was significantly higher than that in the room-temperature thawed group, while the carbonyl content was significantly lower. Sensory evaluation results indicated that the overall score of the ultrasonic-thawed group is significantly higher than that |of the room-temperature thawed group, with the 400 W ultrasonic group achieving the highest sensory score. Pearson correlation analysis indicates that the thawing loss of frozen shrimp is negatively correlated with elasticity and hardness (P<0.05), and positively correlated with TVB-N, TBARS values, and carbonyl content (P<0.05). TVB-N is negatively correlated with hardness, elasticity, and recovery (P<0.05), and positively correlated with TBARS values and carbonyl content (P<0.05). [Conclusion] Ultrasonic thawing improves the texture quality of frozen shrimp compared to room-temperature thawing and effectively inhibits lipid and protein oxidation during the thawing process, with 400 W ultrasonic thawing being the most suitable.
