Currently, studies on organic two-dimensional (2D) materials with special optic-electronic properties are attracting great research interest. However, 2D organic systems possessing promising electrical transport properties are still rare. Here a highly crystalline thin film of a copper coordination polymer, Cu-BHT (BHT=benzenehexathiol), is prepared via a liquid-liquid interface reaction betwee...

This study aimed to assess the acute toxicity in rats of heated and un heatedbutylated hydroxytoluene (BHT). Sunflower oil dissolved BHT, at 98±2ºC by a water bath. The animals were divided into five groups. control group dosage orally with sunflower oil, first treated 250 mg/kg second heated, BHT third 500 fourth BHT. All groups received oral treatment. results showed substantial reduction mot...

Abstract The purpose of this study was to evaluate the thermal stability rice bran extract (RBE) and analyze effect RBE on shelf-life sunflower oil quality characteristics baked cake. evaluated by a Rancimat test using oil. Properties such as moisture content, porosity, crumb density pore area cakes with synthetic antioxidant butylated hydroxytoluene (BHT) were compared. Sensory properties tast...

Hopanoids are steroid-like lipids from the isoprenoid family that are produced primarily by bacteria. Hopanes, molecular fossils of hopanoids, offer the potential to provide insight into environmental transitions on the early Earth, if their sources and biological functions can be constrained. Semiquantitative methods for mass spectrometric analysis of hopanoids from cultures and environmental ...

Recently, a2-adrenoceptor activation was shown to play an important role in the vasoconstriction of normal coronary arteries, whereas in the presence of atherosclerosis, the activation of both a1and a2-adrenoceptors reduces coronary blood flow in humans. a2-Adrenoceptors activate pertussis toxin (PTX)-sensitive G proteins, whereas a1-adrenoceptors couple to PTX-insensitive G proteins. Thus, the...

We investigated the large-scale (10–1000m) and small-scale (mm–cm) variations in size, number and arrangement of air bubbles in the EPICA Dronning Maud Land (EDML) (Antarctica) ice core, down to the end of the bubble/hydrate transition (BHT) zone. On the large scale, the bubble number density shows a general correlation with the palaeo-temperature proxy, dO, and the dust concentration, which me...

Ischemia, and subsequent acidosis, induces neuronal death following brain injury. Oxidative stress is believed to be a key component of this neuronal degeneration. Acute chemical ischemia (azide in the absence of external glucose) and acidosis (external media buffered to pH 6.0) produce increases in intracellular calcium concentration ([Ca2+]i) and inward membrane currents in cultured rat corti...

The antioxidant effect of a trihydroxyflavone extract from Scutellaria baicalensis on oxidation induced by ultraviolet light, was studied with phosphatidylcholine liposome membrane. Also, as standards, the antioxidative activity of baicalin, wogonin, baicalein and butylated hydroxytoluene (BHT) was investigated. Comparison of the protective effects of the compounds studied against photoinduced ...

In the present study, the efficacy of litchi fruit pericarp (LFP) extract (0.5%, 1.0% and 1.5% concentration) in retarding lipid oxidation of cooked sheep meat nuggets was evaluated and compared to butylated hydroxyl toluene (BHT, 100 ppm). The total phenolic content and antioxidant potential of LFP extracts were determined. The thiobarbituric acid reactive substance (TBARS) values were evaluat...

Limb vascular responses to magnesium (Mg2+) and potassium (K+) ions were studied in 19 young patients with borderline hypertension (BHT) and compared with those of 22 age-matched normotensive subjects (NT) by measuring the forearm blood flow response to intra-arterial infusion of magnesium sulfate and potassium chloride using venous occlusion plethysmography. Percent decrements of forearm vascu...
