Article Synopsis
  • - The study analyzed the profiles of non-volatile compounds like caffeine and chlorogenic acid in coffee extracts, using an electronic tongue (E-tongue) to assess taste attributes such as sourness, bitterness, and saltiness.
  • - Volatile compounds responsible for coffee's aroma were identified, with 2-Furanmethanol, benzene ethanol, nonanal, and pyridine detected through an electronic nose (E-nose) and GC-MS-O techniques.
  • - Neurophysiological effects showed that inhaling coffee volatiles led to different brain wave activations in men and women, while drinking coffee produced similar effects by activating mid-beta waves in both sexes.

Ginsenosides, active compounds derived from Panax ginseng, exhibit promising potential in enhancing physical performance. This study investigates the impact of UG0712 (UG), a novel ginsenoside compound, on endurance capacity, body weight, organ weights, blood parameters, and specific transcriptomic changes in liver and muscle tissues using a C57BL/6N mouse model. The mice received UGs orally at three doses: UG50 (50 mg/kg), UG100 (100 mg/kg), and UG200 (200 mg/kg) for a specified duration.

Vegetables and fruits, high in starch and sugars, are promising substrates for bioethanol production, but can also yield valuable nootropic compounds, such as α-glycerylphosphorylcholine (α-GPC). This compound is a known cognitive enhancer that works by increasing the release of acetylcholine, a neurotransmitter essential for learning and memory. In this study, select root and tuber crops, as well as fruits, were subjected to fermentation to observe the co-production of ethanol and α-GPC.

The demand for sustainable and functional plant-based products is on the rise. Plant proteins and polysaccharides often provide emulsification and stabilization properties to food and food ingredients. Recently, chickpea cooking water, also known as , has gained popularity as a substitute for egg whites in sauces, food foams, and baked goods due to its foaming and emulsifying capacities.

The primary aim of this review was to systematically evaluate the literature regarding the effect of pre-, pro-, or synbiotic supplementation in infant formula on the gastrointestinal microbiota. The Cochrane methodology for systematic reviews of randomized controlled trials (RCTs) was employed. Five databases were searched and 32 RCTs (2010-2021) were identified for inclusion: 20 prebiotic, 6 probiotic, and 6 synbiotic.

Asthma is one of the most common inflammatory diseases of the lung worldwide. There has been considerable progress in recent studies to treat and prevent allergic asthma, however, various side effects are still observed in clinical practice. Six-week-old male BALB/c mice were orally administered with either sword bean pod extracts (SBP; 100 or 300 mg/kg) or dexamethasone (DEX; 5 mg/kg) once daily over 3 weeks, followed by ovalbumin sensitization (OVA/Alum.

Cardiovascular disease, the foremost cause of death worldwide, is an overarching disease term that encompasses a number of disorders involving the heart and circulatory system, including atherosclerosis. Atherosclerosis is a primary cause of cardiovascular diseases and is caused by buildup of plaque and narrowing of blood vessels. Epidemiological studies have suggested that environmental pollutants are implicated in atherosclerosis disease progression.

This study investigated the antiobesogenic effects of the inhalation of volatile compounds derived from basil essential oil (BEO) in high fat diet-induced obese rats. A total of 47 volatile compounds were identified in BEO using gas chromatography-mass spectrometry. Major volatile compounds identified by olfactory testing include linalool oxide, linalool, 1-menthene, and carvone.

We explored the physiological effects of inhaling basil essential oil (BEO) and/or linalool and identified odor-active aroma compounds in BEO using gas chromatography/mass spectrometry (GC-MS) and GC-olfactometry (GC-O). Linalool was identified as the major volatile compound in BEO. Three groups of rats were administered BEO and linalool via inhalation, while rats in the control group were not.

Acrolein (Acr) is a reactive aldehyde in the environment. Acr causes oxidative stress and a cascade of catalytic events and has, thereby, been associated with increased risk of pulmonary diseases. Whether apiaceous vegetables (API) consumption can prevent Acr-induced pulmonary toxicity has not yet been explored hence, we investigated the effects of API on Acr-induced pulmonary damages in C57BL/6J mice.

Article Synopsis
  • A new virus called porcine circovirus 4 (PCV4) has been discovered in China and Korea, creating a need for effective detection methods in field samples.
  • Researchers developed a loop-mediated isothermal amplification (LAMP) assay that provides quick and visible results for detecting PCV4 within 40 minutes.
  • This LAMP method is highly sensitive, detecting less than 50 DNA copies, and outperforms traditional methods, making it an ideal option for diagnosing PCV4 in clinical settings, even in labs with limited resources.

A simple reverse transcription loop-mediated isothermal amplification combined with visual detection method (vRT-LAMP) assay was developed for rapid and specific detection of porcine epidemic diarrhea virus (PEDV) in this study, which overcomes the shortcomings of previously described RT-LAMP assays that require additional detection steps or pose a risk of cross-contamination. The assay results can be directly detected by the naked eye using hydroxynaphthol blue after incubating for 40 min at 62 °C. The assay specifically amplified PEDV RNA and no other viral nucleic acids.
