Superionic Conduction in the Plastic Crystal Polymorph of NaPS.

Sodium thiophosphates are promising materials for large-scale energy storage applications benefiting from high ionic conductivities and the geopolitical abundance of the elements. A representative of this class is NaPS, which currently shows two known polymorphs-α and β. This work describes a third polymorph of NaPS, γ, that forms above 580 °C, exhibits fast-ion conduction with low activation energy, and is mechanically soft.

Structural Stability Diagram of ALnPS Compounds (A = Na, K, Rb, Cs; Ln = Lanthanide).

Thiophosphate compounds have been studied extensively in the past for their rich structural variations and for a large variety of interesting properties. Here, we report 11 new phases with the composition ALnPS (A = Na, K, Rb, Cs; Ln = lanthanide). These new thiophosphates crystallize in four different structure types, with the space groups Fdd2, P1̅, P2, and P2/c, respectively.

Copper Selenidophosphates Cu4P2Se6, Cu4P3Se4, Cu4P4Se3, and CuP2Se, Featuring Zero-, One-, and Two-Dimensional Anions.

Five new compounds in the Cu/P/Se phase diagram have been synthesized, and their crystal structures have been determined. The crystal structures of these compounds comprise four previously unreported zero-, one-, and two-dimensional selenidophosphate anions containing low-valent phosphorus. In addition to two new modifications of Cu4P2Se6 featuring the well-known hexaselenidohypodiphosphate(IV) ion, there are three copper selenidophosphates with low-valent P: Cu4P3Se4 contains two different new anions, (i) a monomeric (zero-dimensional) selenidophosphate anion [P2Se4](4-) and (ii) a one-dimensional selenidophosphate anion [Formula: see text], which is related to the well-known gray-Se-like [Formula: see text] Zintl anion.

Touchless Optical Finger Motion Tracking Based on 2D Nanosheets with Giant Moisture Responsiveness.

A new optical touchless positioning interface based on ultrasensitive humidity responsive 1D photonic crystals utilizing the giant moisture dependent swelling capacity of 2D phosphatoantimonate nanosheets is presented. The spatially confined, full spectral color change combined with reversible transparency switching induced by the humidity sheath of a human finger allows for real time, true color lateral finger motion tracking under touchless conditions.

[Percutaneous endoscopic gastrostomy (PEG) in children: indications, the procedure, outcomes, short and long-term complications].

Background: Feeding through tubes placed in the intestine is a useful way of nutritional support in a patient who is unable to eat but has a well functioning gastrointestinal system. Till 1980, the acceptable technique to place a gastrostomy tube was surgical. However, in the past twenty years percutaneous endoscopic gastrostomy (PEG) has replaced surgical gastrostomy in most settings.

Structuring a framework for public health performance-based budgeting: a Georgia case study.

The ability of public health to meet its functional mandates of assessment, assurance, and policy development footline is driven by the system's capacity to meet basic financing needs. To do so, state and local public health leaders must be able to articulate financing needs in terms that are understandable to policy makers and that link funding to anticipated community impact, benefit, and performance. "Rational" budgeting demands imposed by performance-centered budgeting in the states have proved particularly challenging for public health programs.

Adult education program in palliative care for nursing facility physicians: design and pilot test.

Nursing facilities (NF) are important sites for the care of dying patients. Curricula likely to improve end-of-life care are needed for NF physicians. To this end, a model medical school palliative care curriculum was modified for experienced NF physicians.

Nursing home physician educational intervention improves end-of-life outcomes.

Context: Nursing homes are the setting for one of five deaths in the United States. Unfortunately these deaths are often accompanied by pain and symptoms of discomfort.

Objective: To determine if an educational intervention designed for nursing home physicians improves the quality of dying for nursing home residents.

Risk factors for noncompliance in a colposcopy clinic.

Objective: To evaluate demographic characteristics as risk factors for noncompliance with colposcopy clinic follow-up.

Study Design: A retrospective, case-control study was performed on patients evaluated in the Women & Infants' Hospital colposcopy clinic between January 1, 1992, and December 31, 1993. Data extracted from chart review included demographic characteristics, insurance status, smoking status, cytologic and histologic grade treatment received, number of appointments kept and missed, number of attempts to contact the patient and degree of compliance with colposcopy follow-up.

Methods: An interdisciplinary education committee consisting of experts in palliative and hospice care and an expert in educational design and evaluation was established to develop the program. Program development, which is ongoing, includes a comprehensive instructional design phase, vertical integration of the program into the medical school curriculum, and outcome evaluation.

Anaesthesia by intravenous emulsified isoflurane in mice.

An emulsion of isoflurane in Intralipid for intravenous (iv) injection was formulated and its anaesthetic properties determined in mice. The major advantage of iv delivery of volatile agents is to accelerate the induction of anaesthesia by circumventing the anesthetic circuitry and the lung's functional residual capacity. Isoflurane was added to Intralipid in varying concentrations.

Brock transventricular pulmonary valvotomy in patients with pulmonary stenosis: long-term results.

As no long-term results of a blind opening up of the pulmonary valve either by balloon valvoplasty or closed Brock valvotomy have been published, we examined the outcome of 12 patients with valvar pulmonary stenosis 17 +/- 5 (11-22) years after surgery. The Brock valvotomy had been carried out at a mean age of 3 +/- 2.8 (0.

Kinetic model for the biodistribution of an 111In-labeled monoclonal antibody in humans.

Using data from 12 patients, we have analyzed the pharmacokinetics of 111In-9.2.27, an antimelanoma monoclonal antibody, following i.

Monoclonal antibody imaging of human melanoma. Radioimmunodetection by subcutaneous or systemic injection.

Fab fragments of monoclonal antibodies (MoAb) to melanoma, radiolabeled with 131I, were evaluated as diagnostic reagents to determine their ability to localize systemic--MoAb injected intravenously (IV)--or nodal metastatic disease--injected subcutaneously (SQ) at a site proximal to draining lymph nodes. Sixty-one scans were performed (40 IV, 21 SQ) in 59 patients who had injections of 0.2-50 mg of 131I coupled (0.

Nitrous oxide does not hinder the repair of halothane-induced hepatic injury in the rat.

Nitrous oxide administration may limit DNA synthesis by inactivating methionine synthetase, and may thus hamper the repair of an injured organ such as the liver. To test this possibility, we pretreated rats with phenobarbital and exposed them to 0.3 MAC halothane in 9% oxygen for 46 min, followed immediately and again 24 hr later by 70% nitrous oxide (0.

Nitrous oxide, too, is hepatotoxic in rats.

Anesthetic hepatotoxicity was tested under various conditions of hypoxia in rats pretreated with phenobarbital. Administration of 0.3 MAC halothane or fentanyl in 9% oxygen (fractional concentration of inspired oxygen = 0.

Isoflurane does not prevent hepatic injury produced by halothane in rats.

We speculated that the inhibitory effect of isoflurane on the metabolism of halothane might reduce hepatic injury produced by halothane. To test this hypothesis we pretreated male rats with phenobarbital and 24 hr later exposed them to one of three types of anesthesia. One group of rats was anesthetized with 0.

Brief periods of hypoxia can produce hepatic injury in rats.

To determine whether brief periods of hypoxia could produce hepatic injury, we pretreated Sprague-Dawley rats with phenobarbital, deprived them of food for 24 hr, and then exposed them to various hypoxic mixtures of nitrogen and oxygen for various lengths of time. Rats exposed to 6% oxygen for 15 or more minutes had centrilobular injury, the severity of which was directly related to the length of exposure (r = 0.71).

Two-factor requirement for murine megakaryocyte colony formation.

WEHI-3 cell-conditioned medium with the capacity to stimulate megakaryocyte colony formation was separated by Sephadex G-150 column chromatography. The development of colonies containing megakaryocytes was observed only when mixing experiments were performed. Individual fractions did not support megakaryocyte colony growth.
