Cardiovascular disease remains a leading global cause of mortality, demanding effective prevention and management. This systematic review explores the impact of lycopene, prevalent in various fruits, on cardiovascular health. Thirteen randomized and controlled trials were analyzed, involving 385 participants with cardiovascular risk factors. Notable findings included significant blood pressure reductions, particularly among hypertensive individuals, and favorable alterations in lipid profiles. Lycopene interventions also demonstrated potential in mitigating oxidative stress and inflammation markers. While these findings show promise, more rigorously designed studies are essential to determine optimal dosages and durations for precise cardiovascular benefits. In conclusion, lycopene shows potential in managing cardiovascular risk factors, and its role in blood pressure regulation, lipid profile improvement, and antioxidant and anti-inflammatory effects is encouraging. Nonetheless, further research is warranted to provide definitive guidance on integrating lycopene to enhance cardiovascular health.

Rice starch is a natural source of polysaccharides that can be used as a stabilizer, thickener, binder and fat mimetic in various foods. However, untreated starch possesses limited functionality due to its poor water solubility with a densely packed granular structure of amylopectin and amylose chains. Also, it shows weak complexing ability as the only amylose participates in complex formation with a chemical compound. The objective of this study is to improve complexation ability and water solubility of rice starch by 4-α-glucanotransferase (4αGTase) treatment. Complex forming capacity was examined by fully dissolving the 4αGTase-treated rice starch in 90% DMSO by mechanical stirring and mixing with iodine solution with following UV/Vis spectrophotometer measurements. Water solubility of the starch was measured by dissolving in distilled water (5% w/v) with mechanical stirring at 25 °C and 60 °C, and drying the supernatant after centrifugation. The complexing ability of starch was enhanced after the 4αGTase treatment. The absorbance at a peak wavelength increased, as well as the peak wavelength was shifted leftward, indicating that the type of molecules got involved in the complexation was changed. Alteration in the molecule composition and starch composition during the enzyme treatment may be due to disproportionation and cyclization by the 4αGTase. The water solubility (%) of the starch at 25 °C and 60 °C increased by 28-fold with the 4αGTase treatment regardless of the treatment time. The untreated starch showed solubility of 0.15 %, while the solubility of the 4αGTase-treated starch was about 4 - 4.5 % (w/v). It may be due to heat treatment and recrystallization which melted a granular structure and made it easier to be solubilized in water. Moreover, the increased solubility might be attributed to increase in the number of short branched chains and decrease in molecular weight.

Curcumin is an active polyphenolic compound with antioxidant, anti-inflammatory and antitumor properties. Curcumin, however, is highly unstable under physiological conditions due to its low stability in acidic and alkaline conditions. Therefore, the objective of this study was to investigate the effects of enzyme-treated rice starch as a wall material on the stability of curcumin in oil-in-water emulsion under different pH conditions. The rice starch was treated using 4-a-glucanotransferase for different time periods and their molecular weight distribution was measured by HPSEC. Curcumin was encapsulated within lipid droplets of O/W emulsion prepared with Tween 20 and the modified rice starch in the aqueous phase at different concentrations (0, 2.5, 7.5 and 10 wt%). The temperature and pH stability of the system were determined respectively by measuring particle size, zeta potential and retention of the curcumin loaded in the emulsion after one-week storage in the solutions with different pH and temperature conditions. The average molecular weight of the modified starch decreased with treatment time. The 96h treated rice starch had the lowest molecular weight while the 1h treated starch mainly consisted of high molecular weight components. The storage temperature did not significantly influence the stability of curcumin emulsion. However, the particle size of the emulsion with modified starch slightly increased when stored at acidic pH condition, which might be attributed to starch aggregation. The curcumin retention was higher for the samples with the modified starch than the control at all concentrations. The pH stability of the curcumin was also higher than the control at all pH conditions. Specifically, the 1h treated starch showed the best performance regarding curcumin protection in emulsion, which might be attributed to the high viscosity that retarded the curcumin release. Further research needs to be conducted on the mechanism.

Acteoside acts as an anti-oxidative activity and anti-apoptosis in the cells. But, it has been not studied on maturation and development of porcine oocytes. The aims of the present study were to examine the effects of acteoside on the morphological progress of meiosis, developmental competence, and ROS in porcine oocytes. Oocytes were matured in tissue culture medium-199, supplemented with acteoside at various concentrations: 0 (control), 10, 30 and 50 μM. The oocytes maturation rates of groups supplemented with acteoside were no significantly different (81.13, 85.96, 82.95 and 83.68%, respectively). Level of ROS was significantly decreased in acteoside treated group. Furthermore, the parthenogenetic blastocyst rate was significantly improved in 10 μM acteoside treated group compared with control group (44.83 vs. 27.75%). And we investigated effect of acteoside on the oocytes condition represented by cytoplasmic maturation by homogeneous distribution and formation of cytoplasmic organelles and regulation of apoptosis-related genes. In the results. during IVM, 10 μM acteoside treated oocytes showed that the mitochondria and lipid droplet were smaller and homogeneous distribution in cytoplasm compare with control oocytes. And reverse transcription polymerase chain reaction (RTPCR) of parthenogenetic blstocysts revealed that acteoside increased the anti-apoptotic genes (Mcl-1, Bcl-2 and Bcl-xL), whereas reduced the expression of pro-apoptotic genes (Bax and Bak). In conclusion, based on the results, the effect of acteoside on IVM was not attractive. However, in acteoside treated group, cytoplasmic maturation seemed to be improved with morphologically uniform distribution of cytoplasmic organelles. Furthermore, embryonic development in acteoside treated group was significantly highly increased than that of non-treated group. Our results represents that addition of acteoside to the IVM medium has a beneficial effect in physiology of porcine oocytes, providing a improved method for porcine oocytes in vitro. * This work was supported by a grant (Code# PJ008148) from BioGreen21 Program, Rural Development Administration, Republic of Korea.

Several species of the genus Aphidius are used in biological control programs against aphid pests throughout the world and their behavior and physiology are well studied. But despite knowing the importance of sensory organs in their behavior, their antennal structure is largely unknown. In this study, the external morphology and distribution of the antennal sensilla on the antennal of both female and male adults of A. colemani were described using scanning electron microscopy (SEM). Generally, the filaform antennae of males (1,515.20±116.48 ㎛) are longer than females (1,275.06±116.42㎛). Antennae of this species is made up of scape, pedicel and flagellomeres. Male and female antennae differed in the total number of flagellomeres as 15 in males and 13 in females. Female and male antennae of A. colemani has samely seven types of sensilla. We classified sensilla placodea, Bohm bristles, 2 types of sensilla coeloconica, , 2 types of sensilla basiconica as with a tip pore and with wall pores, sensilla trichodea. In addition, the possible functions of the above sensilla types are discussed in light of previously published literature; mechanoreception(Bohm bristles, sensilla coeloconicaⅡ and sensilla trichodea) and chemoreception(sensilla coeloconicaⅠ, sensilla basiconicaⅠ,Ⅱ and sensilla placodea). Future studies on the functional morphology of the antennal sensilla of A. colemani using transmission electron microscopy (TEM) coupled with electrophysiological recordings will likely confirm the functions of the different sensilla identified in this study.
