Abstract
The ravaging effect of drug-resistant bacteria has heightened the need for the development of membrane-soluble antimicrobial peptides (AMPs). However, their potential for clinical use is hindered by issues such as poor biocompatibility, salt sensitivity, and proteolytic lability. In this study, a series of ultrashort stapled cyclization heptapeptides were obtained by inserting all-hydrocarbon staples. StRRL with the highest therapeutic index (TI = 36.3) was selected after evaluating its antibacterial and toxic activity. Furthermore, stRRL demonstrated exceptional performance in high-protease and high-salt environments, making it an effective weapon against bacteria like Escherichia coli in a mouse peritonitis-sepsis model. The membrane lytic mechanism of stRRL, which operates from outside to inside, gives it a low drug-resistant tendency. This suggests that stRRL has the potential to replace antibiotics as a powerful candidate in tackling bacterial infection. In conclusion, the ultrashort all-hydrocarbon stapled antimicrobial amphiphiles inaugurated a novel entrance to the advancements of highly stable peptide compounds.

Abstract
Raised blood pressure is the most common complication worldwide that may lead to atherosclerosis and ischemic heart disease. Unhealthy lifestyles, smoking, alcohol consumption, junk food, and genetic disorders are some of the causes of hypertension. To treat this condition, numerous antihypertensive medications are available, either alone or in combination, that work via various mechanisms of action. Combinational therapy provides a certain advantage over monotherapy in the sense that it acts in multi mechanism mode and minimal drug amount is required to elicit the desired therapeutic effect. Such therapy is given to patients with systolic blood pressure greater than 20 mmHg and/or diastolic blood pressure exceeding 10 mmHg beyond the normal range, as well as those suffering from severe cardiovascular disease. The selection of antihypertensive medications, such as calcium channel blockers, angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), and low-dose diuretics, hinges on their ability to manage blood pressure effectively and reduce cardiovascular disease risks. This review provides insights into the diverse monotherapy and combination therapy approaches used for elevated blood pressure management. In addition, it offers an analysis of combination therapy versus monotherapy and discusses the current status of these therapies, from researchbased findings to clinical trials.

Abstract
Barley is one of the world's oldest cereal crops forming an important component of many traditional diets. Barley is rich in a variety of bioactive phytochemicals with potentially health-promoting effects. However, its beneficial nutritional attributes are not being fully realized because of the limited number of foods it is currently utilized in. It is therefore crucial for the food industry to produce novel barley-based foods that are healthy and cater to customers' tastes. This article reviews the nutritional and functional characteristics of barley, with an emphasis on its ability to improve glucose/lipid metabolism. Then, recent trends in barley product development are discussed. Finally, current limitations and future research directions in glucolipid modulation mechanisms and barley bioprocessing are discussed.

Abstract
In this study, electrospinning of hordein and glutelin extracted from barley was carried out. Different ratios of the glutelin-hordein blends (25:75, 30:70, 35:65) were tested and the operation parameters including voltage, ejection flow rate and needle-to-collector distance were optimized. According to the scanning electron microscope images, the glutelin-hordein 25:75 blend generated at the voltage of 15 kV, the needle-to-collector distance of 150 mm and the ejection rate of 1 mL/h was selected for the fabrication of uniform nanofibers. The apparent viscosity at the ejection point was decreased with increasing the glutelin concentration from 25 to 35 %. Moreover, the Oliveria decumbens essential oil (ODEO) with different loading concentrations (2-4 % (v/v)) was incorporated into the protein blend. Fourier-transform infrared spectra demonstrated the occurrence of the interactions of proteins the ODEO. The encapsulation efficiency of ODEO in the nanofibers was 79.30 %. The presence of ODEO led to inhibition the growth of Staphylococcus aureus, Escherichia coli and Bacillus cereus in a synthetic medium. The optimal nanofibers showed high antioxidnat activity. The results herein showed the possibility of the production of electrospun nanofibers using barley proteins with promising (bio)functionalities for the active food packaging applications.

Abstract
Large numbers of bioactive peptides with potential applications in protecting against human diseases have been identified from plant sources. In this review, we summarized recent progress in the research of plant-derived bioactive peptides, encompassing their production, biological effects, and mechanisms. This review focuses on antioxidant, antimicrobial, antidiabetic, and anticancer peptides, giving special attention to evidence derived from cellular and animal models. Studies investigating peptides with known sequences and well-characterized peptidic fractions or protein hydrolysates will be discussed. The use of molecular docking tools to elucidate inter-molecular interactions between bioactive peptides and target proteins is highlighted. In conclusion, the accumulating evidence from in silico, in vitro and in vivo studies to date supports the envisioned applications of plant peptides as natural antioxidants as well as health-promoting agents. Notwithstanding, much work is still required before the envisioned applications of plant peptides can be realized. To this end, future researches for addressing current gaps were proposed.

Abstract
Natural plants fermented with probiotics exert beneficial effects on hyperlipidemia and gut microbiota disorders. This study aimed to investigate the hypolipidemic activity of fermented black tartary buckwheat (FBTB) in rats with hyperlipidemia induced by a high-fat diet (HFD) in association with the regulation of gut microbiota. Probiotic fermentation by Bacillus sp. DU-106 obviously increased the contents of tyrosine, lysine, total flavonoids, total polyphenols, quercetin, and kaempferol in black tartary buckwheat (BTB) and significantly decreased the rutin content. FBTB treatment for 8 weeks significantly decreased the levels of serum total cholesterol, triglycerides, and low-density lipoprotein cholesterol in HFD-induced hyperlipidemic rats. Western blot analysis further confirmed that the protein expression levels of FXR, SREBP1, and PPARα were altered after FBTB treatment. Moreover, FBTB intervention altered the gut microbiota of HFD-fed rats by increasing the relative abundances of Lactobacillus, Faecalibaculum, and Allobaculum and decreasing the relative abundance of Romboutsia. The relative abundance of Allobaculum was positively correlated with the levels of tyrosine, total flavonoids, total polyphenols, quercetin and kaempferol and negatively correlated with that of rutin. These results suggested that FBTB could alleviate hyperlipidemia and gut microbiota dysbiosis in HFD-fed rats.
