The pedunculopontine nucleus: From posture and locomotion to neuroepigenetics
(AIMS Press, 2019-09)
In this review, we discuss first an example of one of the symptoms of PD, freezing of gait (FOG), then we will turn to the use of deep brain stimulation (DBS) of the pedunculopontine nucleus (PPN) to treat PD, and the ...
Role of G-proteins in the effects of leptin on pedunculopontine nucleus neurons
(Wiley, 2013-06)
The pedunculopontine nucleus (PPN), the cholinergic arm of the reticular activating system, regulates waking and rapid eye movement sleep. Here, we demonstrate immunohistochemical labeling of the leptin receptor signaling ...

Alteration of mesopontine cholinergic function by the lack of KCNQ4 subunit
(Frontiers Media S.A., 2021-07-26)
The pedunculopontine nucleus (PPN), a structure known as a cholinergic member of the reticular activating system (RAS), is source and target of cholinergic neuromodulation and contributes to the regulation of the ...
Thermodynamics of partitioning of propranolol in some organic solvent/buffer systems
(American Chemical Society, 2008-12)
Propranolol (PPN) partitioning thermodynamics was studied at five temperatures in several solvent/buffer systems, namely, cyclohexane (CHAV), octanol (ROHAV), isopropyl myristate (IPMAV), and chloroform (CLFAV). In all ...
The pedunclopontine nucleus and Parkinson's disease
(Academic Press Inc Elsevier Science, 2019-08)
In the last decade, scientific and clinical interest in the pedunculopontine nucleus (PPN) has grown dramatically. This growth is largely a consequence of experimental work demonstrating its connection to the control of ...
Study of the reverse saturation current and series resistance of p-p-n perovskite solar cells using the single and double-diode models
(Academic Press Ltd - Elsevier Science Ltd, 2018-11)
The effects of the offset level and of the doping level in the perovskite layer upon both the reverse saturation current (J 0 ) and the series resistance (R s ) of p-p-n perovskite solar cells have been researched in this ...
Bottom-up gamma and bipolar disorder, clinical and neuroepigenetic implications
(Wiley Blackwell Publishing, Inc, 2019-03)
Objectives: This limited review examines the role of the reticular activating system (RAS), especially the pedunculopontine nucleus (PPN), one site of origin of bottom-up gamma, in the symptoms of bipolar disorder (BD).Methods: ...
Are strigolactones a key in plant–parasitic nematodes interactions? An intriguing question
(Springer, 2021-05)
Plant parasitic nematodes (PPNs) are among the most important pests in agriculture. Chemical inputs are widely used for their control; however, the negative impact of these agrochemicals on environmental and human health ...
