conclusions according to the results of the current study, postoperative analgesia in children was improved in the ketamine group. therefore, for better management of posttonsillectomy pain, low-dose ketamine administration with paracetamol is recommended. results there was no significant difference between the two groups considering demographic data (age, sex distribution, weight and height). ...

Aims . DE Boo is a unique system, with an edge-on view through the debris disk around star. The disk, which analogous to Kuiper belt in Solar System, was reported extend from 74 84 AU central high photometric precision of Characterising Exoplanet Satellite (CHEOPS) provided exceptional opportunity observe small variations light curve due transiting material disk. This chance investigate process...

OBJECTIVES We aimed to determine the hemodynamic effects and postoperative pain control quality of ropivacaine and ketamine addition to ropivacaine in children undergoing inguinal hernia repair with caudal anesthesia. METHODS A total of 45 patients (1-4 years) scheduled to undergo inguinal hernia repair were studied. Anesthesia was induced with sevoflurane in O2/N2O and vecuronium was adminis...

BACKGROUND Adenotonsillectomy is one of the most common surgical procedures in children. Several complications and morbidities are common after nasal surgeries and the most common is pain. Several techniques have been employed to reduce the severity of postoperative pain. One of the preoperative techniques is pre-emptive analgesia through preventive central hypersensitization. This technique is...

55 Cnc e is a transiting super-Earth (radius $1.88\rm\,R_\oplus$ and mass $8\rm\, M_\oplus$) orbiting G8V host star on 17-hour orbit. Spitzer observations of the planet's phase curve at 4.5 $\mu$m revealed time-varying occultation depth, MOST optical are consistent with amplitude offset maximum light. Both broadband high-resolution spectroscopic analyses either high mean molecular weight atmosp...

We report the detection of secondary eclipse hot Jupiter HD 209458 b in optical/visible light using CHEOPS space telescope. Our measurement 20.4 −3.3 +3.2 parts per million translates into a geometric albedo A g = 0.096 ± 0.016. The previously estimated dayside temperature about 1500 K implies that our consists predominantly reflected starlight and is largely uncontaminated by thermal emission....

ABSTRACT We report the discovery of two warm sub-Neptunes transiting bright (G = 9.5 mag) K-dwarf HD 15906 (TOI 461, TIC 4646810). This star was observed by Transiting Exoplanet Survey Satellite (TESS) in sectors 4 and 31, revealing small planets. The inner planet, b, detected with an unambiguous period but outer c, showed only transits separated ∼ 734 d, leading to 36 possible values its perio...

Even among the most irradiated gas giants, so-called ultra-hot Jupiters, KELT-9b stands out as hottest planet thus far discovered with a dayside temperature of over 4500 K. At these extreme irradiation levels, we expect an increase in heat redistribution efficiency and low Bond albedo owed to extended atmosphere molecular hydrogen dissociation occurring on planetary dayside. We present new phot...
