Early growth response transcription factor 1 (EGR1) is expressed in the suprachiasmatic nucleus (SCN) after light stimulation. We used EGR1-deficient mice to address the role of EGR1 in the clock function and light-induced resetting of the clock. The diurnal rhythms of expression of the clock genes BMAL1 and PER1 in the SCN were evaluated by semi-quantitative in situ hybridization. We found no difference in the expression of PER1 mRNA between wildtype and EGR1-deficient mice; however, the daily rhythm of BMAL1 mRNA was completely abolished in the EGR1-deficient mice...

Peripheral immune activation can have profound physiologic and behavioral effects. One mechanism through which immune activation may affect physiology and behavior is through actions on brainstem neuromodulatory systems, such as serotonergic systems. To test this hypothesis, in Experiment 1, adult male BALB/c mice were implanted with telemetric recording devices and then immunized with Mycobacterium vaccae NCTC 11659 (0.1 mg, s.c.; Days - 28, - 14; N = 36). On Day 1, mice received an acute challenge with M...

Daytime and nighttime systolic and diastolic BP was recorded in 23-week-old SHR and Wistar rats by telemetric monitoring. Urine concentrations of sodium, potassium, and calcium were determined in SHR rats during of light (07.00-19.00 h) and dark hours (19.00-07.00 h) at the age of 18, 19, 20, 21, 22, and 23 week; 23-week-old Wistar rats were used as the control. At early stages of the experiment, urine sodium concentration was elevated in SHR rats both at daytime and at night. Thereafter, this value declined and by 22-23 week was significantly lower than in normotensive Wistar rats, but only during daytime...

Drug-induced changes in electroencephalographic (EEG) characteristics in animals may be used to predict central activity of drugs in humans. Previous studies have established that drugs affect EEG characteristics in humans and rodents in a similar manner. However, there has been little work to establish correlations between drug effects on behavioral and EEG characteristics in rats. In the current study, we have simultaneously monitored EEG characteristics during a novel object recognition task (NORT) or open field (OF) test in rats...

Measurement of intraocular pressure (IOP) is an essential tool in monitoring glaucoma. Single IOP assessments during clinical routine examinations represent punctual values and are not able to identify IOP fluctuations and spikes. Telemetric IOP measurements are able to monitor IOP during the day and night, and are location-independent. Six telemetric episcleral IOP sensors were investigated after minimally invasive subconjunctival implantation in 6 eyes of 6 New-Zealand-White rabbits. Three of the 4 edges of the implant were fixated intrasclerally with non-absorbable sutures...

In this research, we developed a portable, three-electrode electrochemical amperometric analyzer that can transmit data to a PC or a tablet via Bluetooth communication. We performed experiments using an indium tin oxide (ITO) glass electrode to confirm the performance and reliability of the analyzer. The proposed analyzer uses a current-to-voltage (I/V) converter to convert the current generated by the reduction-oxidation (redox) reaction of the buffer solution to a voltage signal. This signal is then digitized by the processor...

BACKGROUND: Telemetric intracranial pressure (ICP) monitoring seems to be a promising therapy-supporting option in shunt-treated patients. Benefits become obvious when headaches are unspecific and clinical symptoms cannot be related to possible over- or underdrainage. In this work, a new telemetric device to individually adjust shunt valves according to the ICP was evaluated. METHODS: Between December 2015 and November 2016, 25 patients with suspected suboptimal shunt valve settings underwent insertion of a telemetric ICP sensor ("Sensor Reservoir", Christoph Miethke GmbH & Co...

BACKGROUND: Malformations of cortical development, such as focal cortical dysplasia, are commonly associated with intractable epilepsy. Multiple animal models were created in attempts to recapitulate features of human malformations of cortical development. These manipulations give rise to various focal or diffuse anatomical abnormalities, accompanied by altered susceptibility to epileptic seizures. Both in humans and in models of dysplasia, the question of timing of the initiating insult is important...

Interest in the effects of drugs on the heart rate-corrected JTpeak (JTpc) interval from the body-surface ECG has spawned an increasing number of scientific investigations in the field of regulatory sciences, and more specifically in the context of the Comprehensive in vitro Proarrhythmia Assay (CiPA) initiative. We conducted a novel initiative to evaluate the role of automatic JTpc measurement technologies by comparing their ability to distinguish multi- from single-channel blocking drugs. A set of 5232 ECGs was shared by the FDA (through the Telemetric and Holter ECG Warehouse) with 3 ECG device companies (AMPS, Mortara, and Philips)...

Background: Ecosystems with seasonal fluctuations in climate and food availability present physiological challenges to resident mammals and may cause "stress." The two predominant physiological responses to stressors are (1) the activation of the hypothalamic-pituitary-adrenal axis and (2) the modulation of the autonomic nervous system. To date, the primary indicator for "stress" in wildlife- and zoo animal research are glucocorticoid levels. By measuring the autonomic regulation of cardiac activity, particularly the vagal tone, heart rate variability (HRV) is presently emerging as a suitable indicator of "stress" in farm- and domestic animal research...

BACKGROUND: The Home Monitoring (HM) system of cardiac implantable electronic devices (CIEDs) permits early detection of arrhythmias or device system failures. The aim of this pilot study was to examine how the safety and efficacy of the HM system in patients after ambulatory implanted primary CIEDs compare to patients with a standard procedure and hospitalization. HYPOTHESIS: We hypothesized that HM and their modifications would be a useful extension of the present concepts for ambulatory implanted CIEDs...

Social mammals and birds have a rich repertoire of communication calls. Some call types are uttered rarely but in specific contexts while others are produced in large numbers but are not linked to a specific context. An example for the latter is the "stack" call that zebra finches (Taeniopygia guttata) utter thousands of times per day in a seemingly erratic manner. We quantified this calling activity of captive zebra finches by using on-bird telemetric microphones that permitted a precise temporal resolution...

BACKGROUND: Human African trypanosomiasis or sleeping sickness, caused by the parasite Trypanosoma brucei, leads to neuroinflammation and characteristic sleep/wake alterations. The relationship between the onset of these alterations and the development of neuroinflammation is of high translational relevance, but remains unclear. This study investigates the expression of interferon (IFN)-γ and IFN-inducible chemokine genes in the brain, and the levels of CXCL10 in the serum and cerebrospinal fluid prior to and during the encephalitic stage of trypanosome infection, and correlates these with sleep/wake changes in a rat model of the disease...

PURPOSE: Telemetric temperature capsule systems are wireless, relatively non-invasive and easily applicable in field conditions, and have therefore great advantages for monitoring core body temperature. However, the accuracy and responsiveness of available capsule systems have not been compared previously. Therefore, the aim of this study was to examine the validity, reliability and inertia characteristics of four ingestible temperature capsule systems (i.e. CorTemp, e-Celsius, myTemp and VitalSense)...

REVIEW
Ralph Bosch, Ingrid Mutscher
Remote follow-up of patients with implantable electronic cardiac devices (IECD) is a scientifically well-evaluated and technically mature method. Advantages over conventional follow-up include rapid detection of clinically relevant events (i. e. arrhythmias) and of technical problems. Additionally, telemetric follow-up of IECDs has a high degree of acceptance among both patients as well as health care professionals and carries the potential to reduce health care costs. The implementation of a remote follow-up programme is associated with organisational, infrastructural and legal aspects, which are reviewed...

BACKGROUND: Perioperative hypothermia may affect maternal and neonatal outcomes after obstetric spinal anesthesia. Core temperature is often poorly monitored during spinal anesthesia, due to the lack of an accurate noninvasive core temperature monitor. The aim of this study was to describe core temperature changes and temperature recovery during spinal anesthesia for elective cesarean delivery. We expected that obstetric spinal anesthesia would be associated with a clinically relevant thermoregulatory insult (core temperature decrease >1...

Telemetric monitoring of hemodynamic parameters has become an established standard in experimental models of pulmonary arterial hypertension (PAH). To that purpose, a dedicated catheter is usually implanted through the right ventricular wall of study animals. Drawbacks of this standard technique are: obtained pressures are from the right ventricle and therefore only surrogates for pulmonary arterial pressures, and furthermore, right ventricular myocardium is always damaged to a certain degree. To overcome shortcomings of standard hemodynamic assessment, we modified an established rat model, where severe PAH is induced by left-sided pneumonectomy plus monocrotaline injection...
