Amyotrophic lateral sclerosis（ALS）, identified as a distinct clinical entity by Charcot since the end of the nineteenth century, is a devastating and fatal neurodegenerative disorder that affects motor neurons in the brain, brainstem and spinal cord. Survival of patients with ALS is associated with several factors such as clinical phenotype, age at onset, gender, early presence of respiratory failure, weight loss and treatment with Riluzole（the only disease-modifying drug approved for this disease）. Nowadays, there is still no curative treatment for ALS： palliative care and symptomatic treatment are therefore essential components in the management of these patients. Nevertheless, the scientific knowledge in the field of ALS motor neuron degeneration is growing, with the prospect of new treatments. Based on this physiopathological knowledge, several new therapeutic targets are being studied, involving various mechanisms such as excitotoxicity, neuroinflammation, mitochondrial dysfunction, oxidative stress, RNA metabolism and other attractive concepts. Moreover, it is also important to identify reliable biomarkers that will be essential components for future therapeutic development and study design in ALS. In this review, we present the main recent advances and promising therapeutics and biomarkers in the field of ALS.

Let Ω be a domain in RN. It is shown that a generalized Poincaré inequality holds in cones contained in the Sobolev space Wl,P（）（Ω）, where p（.）： Ω → [1, ∞[ is a variable exponent. This inequality is itself a corollary to a more general result about equivalent norms over such cones. The approach in this paper avoids the difficulty arising from the possible lack of density of the space ;D（Ω） in the space {v ∈ Wl,P（）（Ω）; tr v = 0 on δΩ}. Two applications are also discussed.
