INTRODUCTION Both scarring and nonscarring alopecias have been described with long-term use of epidermal growth factor receptor (EGFR) inhibitors. Current treatments revolve around anti-inflammatory agents such as topical corticosteroid ointments‚ creams‚ and intralesional injections to reduce follicular inflammation. Unfortunately‚ none of these therapies are universally effective. Here‚ we describe a case of erlotinib-induced alopecia refractory to intralesional and topical corticosteroids that

Botulinum neurotoxins (BoNTs) are the most potent toxins known and the causative agent of botulism. Their exceptional toxicity is caused by the highly efficient inhibition of neurotransmitter release at the neuromuscular junction. High affinity binding of BoNTs is mediated by the simultaneous interaction with lipid embedded synaptic vesicle proteins and gangliosides the presynaptic membrane according to the well-established dual-receptor binding model. One peculiarity that is especially pronounced

The nonmutated form of DMPK functions in the production of protein kinase serine; this enzyme plays a role in intracellular communication and in the regulation of myosin phosphate. When DMPK is mutated‚ the proteins CUG-BP1‚ MBNL1 and INSR are displaced causing the splicing of troponin pre-mRNA which causes malfunctions in the cardiac conduction system‚ dominance of a chloride channel that causes myotonia‚ dominance of an insulin receptor that affects the sufficiency of insulin‚ and dominance of

The gaseous hormone ethylene has been shown to influence a diverse array of plant growth and developmental processes‚ thus it is critical for plants to optimize the ethylene production at developmental transitions as well as during stress response. Ethylene is derived from the amino acid methionine‚ which in the first step is converted to S-adenosyl-methionine (AdoMet) by AdoMet synthetase3‚4. The 1-Aminocyclopropane-1-Carboxylic acid Synthase (ACS) catalyzes the conversion of AdoMet to 1-aminocyclopropane-1-carboxylic

Digital signal processing Digital signal processing Digital signal processing (DSP) is the mathematical manipulation of an information signal to modify or improve it in some way. It is characterized by the representation of discrete time‚ discrete frequency‚ or other discrete domain signals by a sequence of numbers or symbols and the processing of these signals. The goal of DSP is usually to measure‚ filter and/or compress continuous real-world analog signals. The first step is usually to
