Non-fibrillar beta-amyloid abates spike-timing-dependent synaptic potentiation at excitatory synapses in layer 2/3 of the neocortex by targeting postsynaptic AMPA receptors.

TL;DR: It is proposed that soluble Aβols trigger the diminution of synaptic plasticity in neocortical pyramidal cell networks during early stages of AD pathogenesis by preferentially targeting postsynaptic AMPA receptors.

TL;DR: It was showed that few VIA-positive women who resulted positive for visual inspection of the cervix with acetic acid had CIN2+ lesions or HPV infection, and colposcopy by Swede score could offer a more accurate screening and selection for immediate treatment of cervical lesions in low-resource settings.

TL;DR: In this paper, a symmetric anti-Hebbian learning rule was proposed to switch between spike timing-dependent plasticity (STDP) rules at pyramidal pairs with pre-and postsynaptic activations.

Input Specificity and Dependence of Spike Timing–Dependent Plasticity on Preceding Postsynaptic Activity at Unitary Connections between Neocortical Layer 2/3 Pyramidal Cells
Misha Zilberter,Carl D. Holmgren,Carl D. Holmgren,Isaac Shemer,Gilad Silberberg,Sten Grillner,Tibor Harkany,Tibor Harkany,Yuri Zilberter,Yuri Zilberter +9 more
TL;DR: It is reported that synaptic connections between L2/3 pyramidal cell pairs are located proximal to the soma, at sites overlapping those of excitatory inputs from other cortical layers.
Evaluation of the accuracy in detecting cervical lesions by nurses versus doctors using a stationary colposcope and Gynocular in a low-resource setting.
Ashrafun Nessa,Joya Shree Roy,Most Afroza Chowdhury,Quayuma Khanam,Romena Afroz,Charlotte Wistrand,Marcus Thuresson,Malin Thorsell,Isaac Shemer,Elisabeth Wikström Shemer +9 more
TL;DR: It is shown that VIA nurses can perform colposcopy and Swede scores obtained by nurses using the Gynocular could offer an accurate cervical diagnostic approach in low resource settings.
