Abstract:

Low density polyethylene (LDPE) films contains BHA, BHT or BHA, BHT, TA were successfully produced by extrusion. Three types of antioxidant films that were L(LDPE), LBB(LDPE+0.5%BHA+0.5%BHT), and LBBT(LDPE+0.5%BHA+0.5%BHT+0.5%TA) was designed. The Mechanics, moisture permeability, scanning electron microscopy (SEM) and antioxidant activity of the film were detected. The results showed that antioxidant consisting of BHA, BHT and TA has a better compatibility with LDPE film. The antioxidant film has a better performance on mechanical strength and the rate of DPPH radical scavenging ability, but

Abstract:

An HPLC method with ultraviolet-visible spectrophotometry detection has been optimized and validated for the simultaneous determination of phenolic compounds, such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) as antioxidants, and octyl methyl cinnamate (OMC) as UVB-filter in several personal care products. The dynamic range was between 1 to 250 mg/L with relative standard deviation less than 0.25% (). Limits of detection for BHA, BHT, and OMC were 0.196, 0.170, and 0.478 mg/L, respectively. While limits of quantification for BHA, BHT, and OMC were 0.593, 0.515, and 1.44

Abstract Because of interference by coeluting capsaicinoids, the commonly used liquid chromatographic method for determining butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) in pepperoni and spice blends is not reliable.

Average recoveries of BHA and BHT from oleoresin spiked at 5 concentrations were 97.6 and 104.3%, respectively. From pepperoni spiked at 4 levels, average recoveries were 79.1 and 87.9%, respectively. The repeatability of the method when applied to

The widespread use of food additives, such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), and tert-butylhydroquinone (TBHQ), has raised concerns about their potential toxicity, especially their hepatotoxicity, nephrotoxicity, and neurotoxicity. This study explores the targets and mechanisms of food additive-induced toxicity using network toxicology. Toxicity predictions of BHA, BHT, and TBHQ were performed using the ProTox-3.0, ADMETlab 3.0, and Xundrug databases, and potential targets were identified using the SwissTargetPrediction, Batman-TCM, SuperPred, and SEA databases

The ratio of BHT-x over total bacteriohopanetetrol (BHT, ubiquitously synthesized by diverse bacteria) has been suggested as a proxy for water column anoxia.

The reaction of BHT oxidation to BHT-OH was included in our calculations. Required input data, initial and boundary conditions were based on laboratory measurements performed for a new PE-HD pipe. Laboratory measurements covered tests of BHT content and homogeneity in pipe material as well as measurements of BHT concentration in water flowing inside the pipe loop with different velocities. The BHT content of the PE-HD pipe and its

The breath holding time (BHT) is under voluntary control to a considerable extentand is dependent on various factors. Pain interrupts ongoing mental processes andmental task stimulates the respiratory complex as a part of generalised central nervoussystem arousal. We hypothesised that the concurrent cold-induced pain and mentaltask may change BHT. In this study BHT with concurrent mental task (MT) or coldinducedpain (CPT) was assessed in healthy individuals (n=25). The objective was toinvestigate the effect of CPT and MT on BHT.

Exposure to particulate matter (PM) has been known to be one of the risk factors to cause allergic asthma, leading to development of respiratory disease. Banhahubak-tang tablet (BHT), a standardized Korean Medicine, is prescribed for neurasthenia, laryngopharyngitis and asthma. In this study, we investigated therapeutic effects of BHT on airway inflammation in ovalbumin (OVA) and PM smaller than 10 μm (PM10)-induced allergic asthma mice. To establish allergic asthma with airway hyper-responsiveness by PM10, BALB/c mice were sensitized and challenged with OVA and PM10, and orally administered B

Cells produce free radicals and antioxidants when exposed to toxic compounds during cellular metabolism. However, free radicals are deleterious to lipids, proteins, and nucleic acids. Antioxidants neutralize and eliminate free radicals from cells, preventing cell damage. Therefore, the study aims to determine whether the antioxidants butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) will ameliorate the maximum dose of acrylamide and alpha (α)-solanine synergistic toxic effects in exposed BEAS-2B cells. These toxic compounds are consumed worldwide by eating potato products. BEAS

The aim of the present study was to determine whether or not voluntary breath-holding time (BHT) changes with the time of the day. BHT with airways closed at end-expiration was measured in six male subjects in the sitting position during the morning (08.00–12.00 hours, on days 1, 6, 7 and 8) and evening (20.00–24.00 hours, on days 2 and 4). BHT increased with the number of days of testing and, at day 8, the morning values averaged 160% of those on day 1. Also, ΔPACO2 [the difference between end-tidal partial pressure of CO2 (PCO2) and alveolar PCO2 (PACO2) at the breaking point] increased in p

Abstract. Bai-Hu-Tang (BHT), derived from the Treatise on Cold Damage, is a classic traditional Chinese medicine formula mainly used to treat fever symptoms caused by excessive heat in the Qi component. Modern medical research has shown that BHT has significant antipyretic effects and can inhibit inflammatory reactions. However, the antipyretic substance basis and mechanism of action of BHT are not fully understood. Although studies have revealed its inhibitory effect on inflammatory factors, there is still a lack of in-depth understanding of its molecular level regulatory mechanisms. This art

In Case 1, a 17-year-old girl with a central neurocytoma was administered intravenous piperacillin–tazobactam for postoperative infection, and BHT developed 12 days later. Her symptoms resolved 8 days after she discontinued the piperacillin–tazobactam and brushed her tongue three times daily.

This phenol was extracted in this study by two methods at the different plant growth stages. One of the methods was better for BHT extraction; the concentration of this phenol is plant growth stage dependent. In this study, the floraison stage has the highest BHT concentration. The antioxidant activity of the plant extract was not related to BHT concentration. The higher antioxidant activity is obtained at seedlings stage.
