Check if the same lab product or an alternative is used in the 5 most similar protocols
Temperature measurements were carried out on 2-month–1.5-year- (5.5-month median) old male and female Id2−/− mice and WT littermates, housed individually in a climate-controlled room set to either normal (21°C ± 1°C) or thermoneutral (30°C ± 1°C) temperature. Body temperature sampling was conducted at 3 h intervals over the 24 h LD cycle. For thermoneutral conditions measurement, all WT and Id2−/− mice used in the studies were allowed to acclimate to thermoneutral temperature for 1 week before temperature measurement. Core body temperature was measured using subcutaneously surgically implanted telemetric transmitters positioned proximal to the iBAT (IPTT 300 transponders, Bio Medic Data Systems, Seaford, DE) following isoflurane anesthetization [3 (link)]. After a week of recuperation, core temperatures were recorded over a 24 h period.

Check if the same lab product or an alternative is used in the 5 most similar protocols
EC sensitization was described previously32 (link). Briefly, EC sensitization consists of three one-week cycles of tape stripping followed by application of OVA or saline. For each cycle, 6 to 8 week-old female mice were anesthetized, and their back skin was shaved and tape-stripped with a film dressing (TegadermTM, 3M) 6 times at day 0 and 3 times at day 3 of each cycle. Two-week rest intervals were observed between the cycles. EC sensitization consisted of applying a 1cm2 gauze containing 100 µg OVA (Sigma-Aldrich) after each tape stripping and securing it with a film dressing. On the last day of sensitization (day 49) mice were challenged intragastrically with 100 mg of OVA in 150 µL of saline buffer (scheme in Fig. 2A). Temperature changes were measured every 5 min following OVA challenge using the DAS-6001 Smart Probe and IPTT-300 transponders (Bio Medic Data Systems) injected subcutaneously. Sera were collected 60 min after challenge.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Tb and activity were continuously measured by telemetry (Mini Mitter/Philips Respironics) using ER4000 energizer/receivers, G2 E-mitters implanted intraperitoneally, and VitalView software with data collected each minute. The hypothermia metric is the nadir Tb at 20–50 minutes after melanocortin dosing. The hyperthermia metric is the mean Tb at 120–300 minutes minus the mean Tb at −150 to −30 minutes relative to dosing. ED50s were calculated by fitting to a four parameter logistic curve using SigmaPlot v12.5. Brown adipose tissue (BAT) temperature and Tb were measured simultaneously in mice carrying two IPTT-300 transponders (Bio-Medic Data Systems), one sutured to the omentum and the other sutured underneath the interscapular BAT.

Spayed female or neutered male ferrets (3-8 months old) were obtained (Triple F Farms, Sayre, PA). After acclimatization, ferrets were implanted subcutaneously with IPTT-300 transponders (BioMedic Data Systems, Seaford, DE) for identification and routine body temperature monitoring. Prior to M. tuberculosis infection, blood, nasal wash, and throat swabs were collected. Animals were pair-housed in individually ventilated stainless steel cages (Allentown, Inc., Allentown, PA) and provided with ferret High Density Diet 5L14 (LabDiet, St. Louis, MO) and fresh water ad libitum. These studies were conducted in accordance with recommendations from the Guide for the Care and Use of Laboratory Animals and within a program accredited by the Association for Assessment and Accreditation of Laboratory Animal Care, International (AAALAC-I). All animal experiments were performed with approval of the Institutional Animal Care and Use Committee at the University of Georgia (NIH Animal Welfare Assurance Number: A3437-01). Infected ferret activity level and respiratory distress (e.g. coughing) were assessed daily, temperatures were measured minimally once per week, and weight was assessed weekly.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Male WT (15 to 35 weeks old) and age-matched ob/ob mice were used for body temperature measurements through an IPTT-300 transponder implanted longitudinally above the shoulder of mouse (Bio Medic Data Systems). To study the thermal effect of uridine, 0.1 g/ml uridine (Sigma) in PBS was administrated to mice (1 g/kg body weight) via intraperitoneal injection or oral gavage. To study the thermal effect of glucose, 0.25 g/ml glucose (Sigma) in H2O was administrated orally to mice (2.5 g/kg body weight). To study the combined effect of glucose and uridine, glucose-uridine solution (0.25 g/ml glucose and 0.1 g/ml uridine in H2O) was administrated orally at the same dose as the study for glucose alone. All the treatment and temperature measurements were performed at ambient room temperature (23° to 25°C), if not specified. A refrigerated incubator at 29°C (Powers Scientific) was used to achieve a near-thermoneutral environment.
