Cordyceps sinensis is a traditional Chinese herbal medicine that has been used for centuries in Asia as a tonic to soothe the lung for the treatment of respiratory diseases. The aim of the present study was to determine the effects of C. sinensi s on airway remodeling in chronic obstructive pulmonary disease (COPD) and investigate the underlying molecular mechanisms. Rats with COPD were orally administered C. sinensis at low, moderate or high doses (2.5, 5 or 7.5 g/kg/day, respectively) for 12 weeks. Airway tissue histopathology, lung inflammation and airway remodeling were evaluated...

AIMS: Rho/Rho-kinase (ROCK) signaling has extensively been shown to take part in mammalian smooth muscle contractions in response to diverse agents yet its role in the contraction of amphibian smooth muscle has not been investigated. Therefore, we aimed to explore any role of this pathway in the contractions of frog stomach smooth. MAIN METHODS: The strips were prepared and suspended in organ baths filled with Ringer solution. Changes in the circular strips of the frog stomach muscle length were recorded isotonically with a force transducer in organ baths...

We have investigated the cardiac and pressor responses to (±)-ephedrine and (-)-ephedrine in pentobarbitone anaesthetised male wistar rats. The tachycardiac responses to (±)- and (-)-ephedrine were similar, but pressor responses to (-)-ephedrine (10mg/kg) were significantly greater than those to (±)-ephedrine, and for both, the pressor response was followed by a small depressor response. Sympathectomy did not affect pressor responses, but significantly increased the later depressor response to both compounds...

BACKGROUND: There is evidence that the sudden unexpected death in epilepsy (SUDEP) risk can be reduced by good seizure control, nocturnal supervision, and by early cardiopulmonary resuscitation if cardiorespiratory arrest occurs in the aftermaths of generalized tonic-clonic seizures (GTCS). These measures, however, may critically depend on the knowledge of patients and relatives on SUDEP. Here, we assessed the basic knowledge on SUDEP of people with epilepsy at a tertiary epilepsy center in Germany...

PURPOSE: Uterine activity plays a crucial role in labor, especially when utero-tonic materials are administered. We aimed to determine the electrical responsiveness of the uterine musculature to labor augmentation with oxytocin using electrical uterine myography (EUM) technology, and to assess whether the kinetics of the EUM device may serve as a predictor for successful vaginal delivery. METHODS: EUM prospectively measured electrical uterine activity in women with singleton gestations at term (≥ 37 + 0 weeks) undergoing labor augmentation by oxytocin administration...

REVIEW
Christian E Elger, Christian Hoppe
Epileptic seizures vary greatly in clinical phenomenology and can markedly affect the patient's quality of life. As therapeutic interventions focus on reduction or elimination of seizures, the accurate documentation of seizure occurrence is essential. However, patient self-evaluation compared with objective evaluation by video-electroencephalography (EEG) monitoring or long-term ambulatory EEG revealed that patients document fewer than 50% of their seizures, on average, and that documentation accuracy varies significantly over time...

Insulin, a pancreatic hormone, can access the central nervous system, activate insulin receptors distributed in selective brain regions and affect various cellular functions such as neurotransmission. We have previously shown that physiologically relevant concentration of insulin potentiates the GABA A receptor-mediated tonic inhibition and reduces excitability of rat hippocampal CA1 neurons. The central nucleus of the amygdala (CeA) comprises heterogeneous neuronal populations that can respond to hormonal stimulus...

The spread of urban development has dramatically altered natural habitats, modifying community relationships, abiotic factors, and structural features. Animal populations living in these areas must perish, emigrate, or find ways to adjust to a suite of new selective pressures. Those that successfully inhabit the urban environment may make behavioral, physiological, and/or morphological adjustments that represent either evolutionary change and/or phenotypic plasticity. We tested for effects of urbanization on antipredator behavior and associated morphology across an urban-wild gradient in the western fence lizard (Sceloporus occidentalis) in two California counties, Santa Barbara and San Luis Obispo...

BACKGROUND: GM1 gangliosidosis is a rare lysosomal storage disorder caused by GLB1 mutations. Because of its extreme rarity and symptoms that overlap with other neurodegenerative diseases, its diagnosis is sometimes challenging, especially in the late infantile form with less severe phenotype. We aim to expand the clinical and genetic spectrum of late infantile GM1 gangliosidosis. METHODS: We confirmed a diagnosis of GM1 gangliosidosis based on GLB1 mutations and/or the deficiency of β-galactosidase activity...

Polygoni Multiflori Radix (PMR) has been commonly used as a tonic in China for centuries. However, PMR-associated hepatotoxicity is becoming a safety issue. Cholestasis often occurs in PMR-induced hepatotoxicity in clinical medicine, but the exact mechanism is not completely understood. An RNA-Seq method was employed, in the present study, to explore the molecular mechanism of cholestatic liver injury induced by PMR, characterized by the hepatic transcriptional response in rats exposed to 1 and 20 g/kg PMR for 90 days...

Growing evidence implicates neurons that project from the lateral parabrachial nucleus (LPBN) to the hypothalamic ventromedial nucleus (VMN) in a neurocircuit that drives counterregulatory responses to hypoglycemia, including increased glucagon secretion. Among LPBN neurons in this circuit is a subset that expresses cholecystokinin (LPBNCCK neurons) and is tonically inhibited by leptin. Since uncontrolled diabetes is associated with both leptin deficiency and hyperglucagonemia, and since intracerebroventricular (icv) leptin administration reverses both hyperglycemia and hyperglucagonemia in this setting, we hypothesized that deficient leptin inhibition of LPBNCCK neurons drives activation of this LPBN→VMN circuit and thereby results in hyperglucagonemia...

Nicotinamide phosphoribosyltransferase (Nampt), also termed visfatin, catalyses the rate‑limiting step in the nicotinamide adenine dinucleotide (NAD) salvage pathway. In addition to its intracellular function (iNampt), extracellular Nampt (eNampt) also affects numerous intracellular signalling pathways. The current study investigated the role of Nampt in the regulation of the hypothalamic‑pituitary‑adrenal (HPA) axis in rats. At 1 h after intraperitoneal administration of eNampt (4 µg/100 g) in adult male rats, serum adrenocorticotropic hormone(ACTH) and aldosterone levels remained unchanged, while corticosterone levels were notably elevated compared with the control group, as determined by ELISA...

Mammalian thalamocortical relay (TCR) neurons switch their firing activity between a tonic spiking and a bursting regime. In a combined experimental and computational study, we investigated the features in the input signal that single spikes and bursts in the output spike train represent and how this code is influenced by the membrane voltage state of the neuron. Identical frozen Gaussian noise current traces were injected into TCR neurons in rat brain slices as well as in a validated three-compartment TCR model cell...
