BACKGROUND: Selenium (Se) is a micronutrient required for many life forms, but toxic at higher concentration. Plants do not have a Se requirement, but can benefit from Se via enhanced antioxidant activity. Some plant species can accumulate Se to concentrations above 0.1% of dry weight and seem to possess mechanisms that distinguish Se from its analog sulfur (S). Research on these so-called Se hyperaccumulators aims to identify key genes for this remarkable trait and to understand ecological implications...

Iodine is a beneficial element for human but very lowly represented in our diet. Iodine-enriched vegetables could boost the iodine content in the food chain. Despite being a beneficial element for plant, little is known about the effect of different iodine forms on plant growth. This work analyses the effect of uptake of mineral (KI) and organoiodine (5-iodosalicylic acid, 5-ISA; 3,5-diiodosalicylic acid, 3,5-di-ISA; 2-iodobenzoic acid, 2-IBeA; 4-iodobenzoic acid, 4-IBeA) compounds on tomato plants at an early stage of vegetative growth...

Salicylic acid alleviates lead toxicity in Brassica juncea (L.) by promoting growth under non-stress and activating stress-defense mechanism (s) under lead stress conditions. It also boosts the ascorbate-glutathione cycle and thus helps in minimizing oxidative and DNA damage. Brassica juncea plants were exposed to different concentrations (0, 500, 1000 and 2000 mg kg-1 ) of lead (Pb) and subsequently sprayed with 0.5 mM of salicylic acid (SA) to check for morphological and leaf gas exchange parameters like transpiration rate (E), stomatal conductance (GH2 O), net photosynthetic rate (A) and maximum quantum yield of PS II (Fv /Fm )...

This study investigated the regulatory role of exogenous salicylic acid (SA) in rice and its effects on toxic reactive oxygen and nitrogen species during short-term salinity stress. SA application (0.5 and 1.0 mM) during salinity-induced stress (100 mM NaCl) resulted in significantly longer shoot length and higher chlorophyll and biomass accumulation than with salinity stress alone. NaCl-induced reactive oxygen species production led to increased levels of lipid peroxidation in rice plants, which were significantly reduced following SA application...

In this study, we investigated the ameliorative effects of salicylic acid (SA), metal ion (Fe(II)), and plant growth-promoting bacteria Burkholderia sp. D54 (B) on two tomato genotypes with different Cd tolerances under Cd stress, viz. Liger (Cd tolerant) and Tabd (Cd sensitive). The plant biomass, Cd accumulation, antioxidative response, pigment content and photosynthetic performance were determined. According to the results, exogenous application of SA, Fe(II) and Burkholderia sp. D54 or their complex effectively reduced Cd accumulation and increased biomass of root, stem and leaves in both Cd sensitive and Cd tolerant genotypes...

Palmoplantar keratodermas (PPK) are heterogeneous disorders characterized by abnormal keratinization. Especially, punctate PPK (PPPK), one of the subtypes of hereditary PPK, is a rare punctate keratoderma characterized by tiny "raindrop" keratoses having a tendency to coalesce on the edge of soles, which are exposed to sustained pressure. If typical punctate lesions are confined to the palms and soles and the patient has a family history and late onset, it can be considered as PPPK type I (PPKP1), also called Buschke-Fisher-Brauer disease...

The age-associated deterioration in cellular and organismal functions associates with dysregulation of nutrient-sensing pathways and disabled autophagy. The reactivation of autophagic flux may prevent or ameliorate age-related metabolic dysfunctions. Non-toxic compounds endowed with the capacity to reduce the overall levels of protein acetylation and to induce autophagy have been categorized as caloric restriction mimetics (CRMs). Here, we show that aspirin or its active metabolite salicylate induce autophagy by virtue of their capacity to inhibit the acetyltransferase activity of EP300...

Bradysia procera is a serious insect pest of Panax ginseng plants. This study was conducted to determine the toxicity and mechanism of action of three phenylpropanoids, three terpenoids, and a ketone from Syzygium aromaticum bud methanol extract and hydrodistillate against third-instar larvae and eggs of B. procera. In a filter-paper mortality bioassay, methyl salicylate (LC50 , 5.26μg/cm2 ) was the most toxic compound, followed by 2-nonanone, eugenol, and eugenyl acetate (8.77-15.40μg/cm2 ). These compounds were significantly less toxic than either thiamethoxam, clothianidin, or cypermethrin...

Muconic acid (MA) is a dicarboxylic acid used for the production of industrially relevant chemicals such as adipic acid, terephthalic acid, and caprolactam. Because the synthesis of these polymer precursors generates toxic intermediates by utilizing petroleum-derived chemicals and corrosive catalysts, the development of alternative strategies for the bio-based production of MA has garnered significant interest. Plants produce organic carbon skeletons by harvesting carbon dioxide and energy from the sun, and therefore represent advantageous hosts for engineered metabolic pathways towards the manufacturing of chemicals...

BACKGROUND/OBJECTIVES: The threshold salicylate concentration commonly recommended to initiate extracorporeal elimination, in the absence of significant end-organ toxicity, is 100 mg/dL. Unfortunately, the grade of evidence to support this decision is low. Our primary aim is to describe highest reported salicylate concentrations in patients who died from acute salicylate ingestions. Our secondary aim is to determine if age or coingestants varied with highest reported salicylate concentration...

Salicylic acid (SA) has a long history of safe use as ingredient in topical cosmetic products. In 2016, the Committee for Risk Assessment of the European Chemicals Agency proposed to classify SA as a Category 2 reproductive toxicant based on adverse developmental effects in animal toxicity studies. This hazard-based classification (based on mg/kg doses) requires a reassessment of the safety of the current SA concentrations in cosmetic consumer products. Herein, a safety reassessment was performed in which margins of safety were calculated based on literature data on the NOAEL plasma exposure levels from animal reproductive toxicity studies with ASA (rapidly converts to SA in plasma), human SA plasma levels from oral exposure to ASA and human dermal exposure to SA-containing cosmetic products...

The known metallotherapeutic [Ag(salH)]2 (AGSAL-1) of salicylic acid (salH2), was used for the development of new efficient silver based material for wounds healing. AGSAL-1 was characterized by spectroscopic techniques and X-ray crystallography. The wound healing epithelialization of AGSAL-1 was investigated by the means of scratch assay against immortalized human keratinocytes (HaCaT) cells. The anti-inflammatory activity of AGSAL-1 was evaluated by monitoring the catalytic peroxidation of linoleic acid to hydroperoxylinoleic acid by the enzyme lipoxygenase (LOX)...

Boron (B) toxicity often limits crop yield and the quality of production in agricultural areas. Here, we investigated the effects of calcium (Ca), silicon (Si) and salicylic acid (SA) on development of B toxicity, B allocation in canola (Brassica napus cultivar Sarw 4) and its role in non-enzymatic antioxidants in relation to yield of this cultivar under B toxicity. Canola seedlings were subjected to four B levels induced by boric acid in the absence or presence of Ca, Si and SA. The results showed that Ca, Si and SA addition ameliorated the inhibition in canola growth, water content (WC), and improved siliqua number, siliqua weight and seed index...

Neonicotinoids (neonics) are remarkably effective as plant systemics to control sucking insects and for flea control on dogs and cats. The nitroimines imidacloprid, clothianidin, thiamethoxam, and dinotefuran are the leaders among the seven commercial neonics that also include the nitromethylene nitenpyram, the nitromethylene-derived cycloxaprid, and the cyanoimines acetamiprid and thiacloprid. Honey bees are highly sensitive to the nitroimines and nitromethylenes, but the cyanoimines are less toxic. All neonics are nicotinic acetylcholine receptor (nAChR) agonists with a common mode of action, target-site cross-resistance, and much higher potency on insect than mammalian nAChRs at defined binding sites...

Early inhibition of inflammation suppresses the carcinogenic process. Aspirin is the most commonly used non-steroid anti-inflammatory drugs (NSAIDs), and it irreversibly inhibits cyclooxygenase-1 and -2 (COX1, COX2). Multiple randomized clinical trials have demonstrated that aspirin offers substantial protection from colon cancer mortality. The lower aspirin doses causing only minimal gastrointestinal disturbance, ideal for long-term use, can achieve only partial and transitory inhibition of COX2. Aspirin's principal metabolite, salicylic acid, is also found in fruits and vegetables that inhibit COX2...
