Amnestic mild cognitive impairment (aMCI) is a transitional state between normal aging and Alzheimer's disease (AD). However, not all aMCI patients are observed to convert AD dementia. Therefore, developing predictive algorithm for the conversion of dementia important. Parametric methods, such as logistic regression, have been developed; however, it difficult reflect complex patterns, non-linear relationships interactions variables. this study aimed improve power patients' by using an...

This paper proposes a new method for occupancy map building using mixture of Gaussian processes. We consider maps as binary classification problem positions being occupied or not, and apply Particularly, since the computational complexity processes grows O(n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> ), where n is number data points, we divide training into small subsets The procedure our consists three steps. First, cluster...

Abstract We aimed to determine somatic mutational profiles of stage II/III gastric cancers (GCs) according their tumor microenvironment immune types (TMITs), which classify cancer based on co‐assessment PD‐L1 expression and CD8 + infiltrating lymphocytes. Eighty patients with GC were classified as follows: TMIT I (PD‐L1 /CD8 High ), II − Low III IV ). Deep targeted sequencing using a panel 170 cancer‐related genes was performed an Illumina HiSeq‐2500 system. Most frequently mutated included...

Dendritic spine is a small membranous protrusion from neuron's dendrite that typically receives input an axon terminal at the synapse. Memories are stored in synapses which consist of spines and presynapses. Rapid modulations dendritic induced by hippocampal sex steroids, including dihydrotestosterone (DHT), testosterone (T), estradiol (E2), essential for synaptic plasticity. Molecular mechanisms underlying rapid non-genomic modulation through receptors androgen (AR) estrogen (ER) as well...
