Capping Effects on Spin and Charge Excitations in Parent and Superconducting Nd_{1-x}Sr_{x}NiO_{2}.

Superconductivity in infinite layer nickelates Nd_{1-x}Sr_{x}NiO_{2} has so far been achieved only in thin films, raising questions on the role of substrates and interfaces. Given the challenges associated with their synthesis it is imperative to identify their intrinsic properties. We use resonant inelastic x-ray scattering to investigate the influence of the SrTiO_{3} capping layer on the excitations of Nd_{1-x}Sr_{x}NiO_{2} (x=0 and 0.

z=2 Quantum Critical Dynamics in a Spin Ladder.

By means of inelastic neutron scattering we investigate finite temperature dynamics in the quantum spin ladder compound (C_{5}H_{12}N)_{2}CuBr_{4} (BPCB) near the magnetic field induced quantum critical point with dynamical exponent z=2. We observe universal finite-temperature scaling of the transverse local dynamic structure factor in spectacular quantitative agreement with long-standing theoretical predictions. At the same time, already at rather low temperatures, we observe strong nonuniversal longitudinal fluctuations.

Splenic Hematoma Mimicking Rupture Uterus: A Diagnostic Dilemma.

Spontaneous splenic hematoma occurring during pregnancy is a rare entity. It often occurs in preexisting pathology of the spleen such as thalassemia or infectious etiologies such as malaria, typhoid, dengue, or infectious mononucleosis but most commonly after a trauma. The occurrence of splenic hematoma during pregnancy without any underlying cause is rare.

Hyperparathyroidism during Pregnancy- A Diagnostic and Therapeutic Challenge.

Primary Hyperparathyroidism (PHP) is a rare event in pregnancy; Maternal complications in PHP patients can be as high as 67%. It can be overlooked easily because of many similar complaints shared by hyperparathyroidism and pregnancy such as nausea and vomiting, gastritis, bone aches, easy fatigability. Hypercalcemic crisis can develop resulting in coma and death.

Post-Caesarean Drain Placement - Minor Procedure Leading to Major Complication.

Intra abdominal drain insertion in doubtful cases has been practised since many years. It may be associated with certain minor as well as major complications like drain site haemorrhage, infection, intestinal perforation and even visceral herniation from the site. Herein, we report a case of 28-year-old unbooked GPL at 33 weeks gestation with previous caesarean, who underwent Lower Segment Caesarean Section (LSCS) in view of breech presentation in labour.

Admission Cardiotocography: A Predictor of Neonatal Outcome.

Background: Screening for fetal distress is a big challenge for obstetricians. Labor admission test by cardiotocography (CTG) can be utilized to differentiate between mothers, in whom continuous fetal monitoring is needed and those who can be managed by intermittent auscultation. Admission CTG is commonly used screening test which aims to identify on admission to the delivery unit the fetus at increased risk of intrapartum hypoxia.

The effect of injection speed on the spinal block characteristics of hyperbaric bupivacaine 0.5% in the elderly.

Purpose: The purpose of this prospective, randomized, double-blind study was to compare anesthetic characteristics after two speeds of intrathecal injection of hyperbaric bupivacaine in elderly patients.

Methods: Fifty-six patients, aged ≥65 years, undergoing transurethral surgery under spinal anesthesia were allocated randomly to two groups according to rate of intrathecal injection of 2 ml hyperbaric bupivacaine 0.5%: group Fast (maximum possible rate; mean 0.

A combination of fentanyl-midazolam-propofol provides better intubating conditions than fentanyl-lignocaine-propofol in the absence of neuromuscular blocking agents.

Background: The use of propofol and adjuvants such as opioids, benzodiazepines and local anaesthetic agents, may provide adequate conditions for tracheal intubation without the need for neuromuscular blocking agents. In this randomized, double-blind study, intubating conditions after induction of anaesthesia with propofol, midazolam and fentanyl were compared with those after propofol, lignocaine and fentanyl.

Methods: In 80 ASA I/II adult patients undergoing elective gynaecological surgery, intubating conditions were compared after induction of anaesthesia with a fentanyl 2 microg/kg, midazolam 0.

Longitudinal assessment of posttraumatic stress disorder and depression after exposure to traumatic death.

Little is known of the specific effects of exposure to traumatic death, an important dimension of many disasters. This study examined acute and long-term intrusive and avoidant symptoms, depression, and posttraumatic stress disorder (PTSD) in disaster workers exposed to traumatic death after the USS Iowa gun turret explosion. Fifty-four volunteer body handlers were assessed at 1, 4, and 13 months.
