This health technology assessment evaluated the efficacy of pharmacological treatment in patients with orofacial pain. Randomised controlled trials were included if they reported pharmacological treatment in patients ≥18 years with chronic (≥3 months) orofacial pain. Patients were divided into subgroups: TMD-muscle [Temporomandibular disorders (TMD) mainly associated with myalgia]; TMD-joint (TMD mainly associated with temporomandibular joint pain); and Burning mouth syndrome (BMS). The primary outcome was pain intensity reduction after pharmacological treatment...

BACKGROUND: Genetic techniques rendering murine models a popular choice for neuroscience research has led to important insights on neural networks controlling locomotor function. Using genetically altered mouse models for in vivo, electrophysiological studies in the adult state could validate key principles of locomotor network organization that have been described in neonatal, in vitro preparations. NEW METHOD: The experimental model presented here describes a decerebrate, in vivo adult mouse preparation in which focal, electrical midbrain stimulation was combined with monitoring lumbar neural activity and motor output after pre-collicular decerebration and neuromuscular blockade...

Brain structure and functions are significantly affected by enriched environment (EE). Rodent and rhesus monkeys raised in EE will increase myelination in development, and these increase correlate with improved cognitive functions on learning and memory. However, whether and how EE influences remyelination in the adult remained undefined. Here, we used a cuprizone-induced demyelination mouse model demonstrate that EE significantly enhances remyelination. This EE-regulated remyelination is associated with improved motor skills...

The physiological functions of epidermal cells are largely determined by their diverse morphologies. Most flowering plants have special conical-shaped petal epidermal cells that are thought to influence light capture and reflectance, and provide pollinator grips, but the molecular mechanisms controlling conical cell shape remain largely unknown. Here, we developed a live-confocal imaging approach to quantify geometric parameters of conical cells in Arabidopsis thaliana (A.thaliana). Through genetic screens, we identified katanin (KTN1) mutants showing a phenotype of decreased tip sharpening of conical cells...

REVIEW
Alexander Panossian
Adaptogens are stress-response modifiers that increase an organism's nonspecific resistance to stress by increasing its ability to adapt and survive. The classical reductionist model is insufficiently complex to explain the mechanistic aspects of the physiological notion of "adaptability" and the adaptogenic activity of adaptogens. Here, I demonstrate that (1) the mechanisms of action of adaptogens are impossible to rationally describe using the reductionist concept of pharmacology, whereas the network pharmacology approach is the most suitable method; and (2) the principles of systems biology and pharmacological networks appear to be more suitable for conceptualizing adaptogen function and are applicable to any phytochemical...

As recorded in Traditional Chinese Medicine (TCM) theory, Gancao (Glycyrrhizae Radix et Rhizoma) could weaken the pharmacological effect or increase the toxicity of Yuanhua (Genkwa Flos). However, the theory has been suspected due to lack of evidence. Here, we investigate whether Gancao could weaken Yuanhua's diuretic effect, if so, which chemicals and which targets may be involved. Results showed that Yuanhua exerted diuretic effect through down-regulating renal AQP 2, without electrolyte disturbances such as K(+) loss which has been observed as side-effect of most diuretics...

In silico modeling of blood-brain barrier (BBB) permeability plays an important role in early discovery of central nervous system (CNS) drugs due to its high-throughput and cost-effectiveness. Natural products (NP) have demonstrated considerable therapeutic efficacy against several CNS diseases. However, BBB permeation property of NP is scarcely evaluated both experimentally and computationally. It is well accepted that significant difference in chemical spaces exists between NP and synthetic drugs, which calls into doubt on suitability of available synthetic chemical based BBB permeability models for the evaluation of NP...

The pharmacological modulation of glutamatergic neurotransmission to improve cognitive function has been a focus of intensive research, particularly in relation to the cognitive deficits seen in schizophrenia. Despite this effort there has been little success in the clinical use of glutamatergic compounds as procognitive drugs. Here we review a selection of the drugs used to modulate glutamatergic signalling and how they impact on cognitive function in rodents and humans. We highlight how glutamatergic dysfunction, and NMDA receptor hypofunction in particular, is a key mechanism contributing to the cognitive deficits observed in schizophrenia, and outline some of the glutamatergic targets that have been tested as putative procognitive targets for the disorder...

State dependent activity of locus coeruleus (LC) neurons has long suggested a role for noradrenergic modulation of arousal. However, in vivo insights into noradrenergic arousal circuitry have been constrained by the fundamental inaccessibility of the human brain for invasive studies. Functional magnetic resonance imaging (fMRI) studies performed during site-specific pharmacological manipulations of arousal levels may be used to study brain arousal circuitry. Dexmedetomidine is an anesthetic that alters the level of arousal by selectively targeting α2 adrenergic receptors on LC neurons, resulting in reduced firing rate and norepinephrine release...

Brain inflammaging is increasingly considered as contributing to age-related cognitive loss and neurodegeneration. Despite intensive research in multiple models, no clinically effective pharmacological treatment has been found yet. Here, in the mouse model of brain senescence SAMP8, we tested the effects of proinsulin, a promising neuroprotective agent that was previously proven to be effective in mouse models of retinal neurodegeneration. Proinsulin is the precursor of the hormone insulin but also upholds developmental physiological effects, particularly as a survival factor for neural cells...

Curcumin is known as a natural dietary polyphenol which is extracted from Curcuma longa L. It has been shown that curcumin has a variety of pharmacological effects such as antioxidant, anti-cancer, anti-inflammatory, and anti-microbial activities. Anti-cancer effects of curcumin are due to targeting of a wide range of cellular and molecular pathways involved in cancer pathogenesis including NF-kB, MAPK, PTEN, P53, and microRNAs (miRNA) network. Multiple lines of evidence have indicated that curcumin exerts its therapeutic effects via regulating miRNA expression (e...

We investigated the physical role of the extracellular matrix in vascular homeostasis in the basal chordate Botryllus schlosseri, which has a large, transparent extracorporeal vascular network encompassing areas >100 cm(2) We found that the collagen crosslinking enzyme lysyl oxidase is expressed in all vascular cells, and that in vivo inhibition using ß-aminopropionitrile (BAPN) caused a rapid, global regression of the entire network, with some vessels regressing >10 mm within 16 hours. BAPN treatment changed the ultrastructure of collagen fibers in the vessel basement membrane, and the kinetics of regression were dose-dependent...

Randomized clinical trials provide the gold standard evidence base to guide clinical practice. Despite major advances in trial design, pediatric clinical trials are still difficult to perform and pose unique challenges, including the need to consider the impact of developmental changes in trial design. Advances within pediatric rheumatology combined with the need to comply with legislative requirements have driven new approaches to performing pediatric clinical trials such as utilization of large research networks, incorporation of patient and family stakeholders in the planning and implementation of clinical trials, and the development of novel trial designs...
