The method of claim , wherein the neuron related disease is neuron damage caused by hypoxia. The present invention relates to a novel medical use of compound 5α-androstane (alkyl)-3β,5,6β-triol (hereinafter abbreviated as YC-6).Acute Ischemic Stroke (AIS) is conventionally treated mainly by thrombolysis or neuroprotection. Neuroprotection refers to medicament or measures, during treatment of AIS, that are able to inhibit pathological and biochemical reactions of brain tissue caused by ischemia, interfere with various pathways of ischemic cascade and prolong survival of neurons.Neuroprotection has currently become one of the research hotspots in the field of AIS treatment. Various neuroprotectants are under clinical development, the mechanism of which is to prevent or limit brain damage resulted from ischemia by blocking various harmful pathological processes due to ischemia, so as to reduce brain tissue death and promote function recovery. The neuroprotectants can reduce cerebral infarct size; do not result in hemorrhage complication that may occur during thrombolytics or anticoagulants therapy; and can be used without confirmation of etiology, making early treatment possible. The therapeutic effect of neuroprotectants is therefore promising.There is no neuroprotectant yet, however, that has been proven safe and effective. Drugs that are under clinical trials and have potential value of clinical application include calcium channel blockers (CCB), calcium channel modulators, glutamate release ...

Methods are provided for the epigenetic analysis of cell-free DNA using organic boranes to convert oxidized 5-methylcytosine residues in the cell-free DNA to dihydrouracil (DHU) residues. Cell-free DNA is contacted with an organic borane selected to successively bring about reduction, deamination, and decarboxylation of oxidized 5-methylcytosine residues such as 5-carboxymethylcytosine and 5-formylcytosine, resulting in DHU residues in place thereof. Following amplification, the treated cell-free DNA is sequenced, with the DHU residues read as thymine residues. Reaction mixtures, kits and additional methods are also provided, as are related methods for the epigenetic analysis of DNA, including cell-free DNA.

In general, neurotransmitters are responsible for regulating the conductance of ions across neuronal membranes. At rest, the neuronal membrane possesses a potential (or membrane voltage) of approximately −70 mV, the cell interior being negative with respect to the cell exterior. The potential (voltage) is the result of ion (K, Na, Cl, organic anions) balance across the neuronal semipermeable membrane. Neurotransmitters are stored in presynaptic vesicles and are released under the influence of neuronal action potentials. When released into the synaptic cleft, an excitatory chemical transmitter such as acetylcholine will cause membrane depolarization (change of potential from −70 mV to −50 mV). This effect is mediated by postsynaptic nicotinic receptors which are stimulated by acetylcholine to increase membrane permeability to Na ions. The reduced membrane potential stimulates neuronal excitability in the form of a postsynaptic action potential.In the case of the GABA receptor complex (GRC), the effect on brain excitability is mediated by GABA, a neurotransmitter. GABA has a profound influence on overall brain excitability because up to 40% of the neurons in the brain utilize GABA as a neurotransmitter. GABA regulates the excitability of individual ...

The present application is a continuation of U.S. patent application Ser. No. 15/077,099, filed Mar. 22, 2016, which claims priority to U.S. Provisional Application Ser. No. 62/136,813 entitled “NOVEL CYTOTOXIC AGENTS THAT PREFERENTIALLY TARGET LEUKEMIA INHIBITORY FACTOR (LIF) AND MDM2 FOR THE TREATMENT OF MALIGNANCIES AND AS NEW CONTRACEPTIVE AGENTS” filed Mar. 23, 2015, both of which are incorporated herein by reference in their entirety.The invention generally relates to new anti-cancer compounds, acting through a new mechanism of action by simultaneous inhibition of leukemia inhibitory factor (LIF) and MDM2.Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. If the spread is not controlled, it can result in death. Cancer may affect people at all ages, but risk for the more common varieties tends to increase with age. Cancer is caused by external factors, such as tobacco, infectious organisms, and an unhealthy diet, and internal factors, such as inherited genetic mutations, hormones, and ...
