The effect of a sequential stimulation by mustard oil and noxious heat or cold on the phosphorylation of ERK1/2 in sensory afferents was investigated. The stimuli were applied to the rat hind paw and phospho-ERK1/2 (p-ERK1/2) was measured by fluorescence-immunohistochemistry in the lumbar dorsal root ganglia (DRGs) neurons. All stimuli lead to a significant increase in the number of small size DRG cells displaying cytoplasmic staining for p-ERK1/2. The combination of mustard oil with cold significantly increased the number of cells with cytoplasmic staining above the level obtained with cold stimulus alone, however this was not observed with the combination of mustard oil and heat. Nuclear staining was weak and was found increased by mustard oil combined with cold stimulation. Mustard oil is known to activate TRPA1 and TRPV1 channels, heat TRPV1, and cold TRPA1 and TRPM8. The present findings shed new light on the DRG cell populations reacting with cytoplasmic and nuclear staining for p-ERK1/2 following sequential irritant chemical and thermal stimuli to the skin.

Fungal lipases are the leading industrial biocatalyst due to their broad applications, but high cost limits their commercial usage. The low-cost agri-residues substrates can reduce the cost of lipase production. However, the compatibility of agri-residue with fungal species, recovery process of lipase and stability of the enzyme are crucial steps.

Diamondback moth (Lepidoptera: Plutellidae; Plutella xylostella L.) is a specialist insect of the Brassicaceae family, damaging economically important crops, such as cabbage and cauliflower. Glucosinolates, also known as 'mustard oil bombs' are present in all Brassicaceae members, of which sinigrin (allyl-glucosinolate or 2-propenyl-glucosinolate) is a major aliphatic compound.

Edible oils and ghee are vital parts of our daily culinary practices. In recent years, owing to heightened demand in the domestic and global markets, consistent reports regarding the adulteration of edible oils and ghee with substandard ingredients have been reported. Adulteration in edible oils is widespread, with distinctive contaminants, including cottonseed, mineral, and lower-cost oils like palm olein.

A multivariate nutritional analysis indicated that the consumption of erucic acid-rich food, a fatty acid (FA) found primarily in rapeseed and mustard oil, was positively correlated with higher counts of lactic acid bacteria (LAB). Furthermore, we showed N6.2, as well as other species of LAB tested from the former genus, were able to efficiently use erucic acid (EA) as the source of FA.

Background: Previous case-control studies have suggested that environmental factors including exposure to pesticides and organic materials, diet and medications have an important role in the pathogenesis of pemphigus vulgaris. These studies lacked geographical population controls and had less than three controls per case.
Objective: To identify environmental and occupational risk factors associated with the development of pemphigus vulgaris (PV) and bullous pemphigoid (BP).
