Pseudosymmetry in Tetragonal Perovskite SrIrO Synthesized under High Pressure.

In this study, we report a tetragonal perovskite structure of SrIrO (4/, = 3.9362(9) Å, = 7.880(3) Å) synthesized at 6 GPa and 1400 °C, employing the ambient pressure monoclinic SrIrO with distorted 6 structure as a precursor.

Advanced Characterization of the Spatial Variation of Moiré Heterostructures and Moiré Excitons.

In this short review, an overview of recent progress in deploying advanced characterization techniques is provided to understand the effects of spatial variation and inhomogeneities in moiré heterostructures over multiple length scales. Particular emphasis is placed on correlating the impact of twist angle misalignment, nano-scale disorder, and atomic relaxation on the moiré potential and its collective excitations, particularly moiré excitons. Finally, future technological applications leveraging moiré excitons are discussed.

Supercontinuum in integrated photonics: generation, applications, challenges, and perspectives.

Frequency conversion in nonlinear materials is an extremely useful solution to the generation of new optical frequencies. Often, it is the only viable solution to realize light sources highly relevant for applications in science and industry. In particular, supercontinuum generation in waveguides, defined as the extreme spectral broadening of an input pulsed laser light, is a powerful technique to bridge distant spectral regions based on single-pass geometry, without requiring additional seed lasers or temporal synchronization.

Increase in white cell and neutrophil counts during the first eighteen weeks of treatment with clozapine in patients admitted to a long-term psychiatric care inpatient unit.

Introduction: Clozapine is an antipsychotic drug that has shown to be more effective than other antipsychotics in the treatment of schizophrenia, but its use is limited due to its side effects, particularly by the risk of causing agranulocytosis. A study was made on the variations in white cell and neutrophil counts in patients treated with clozapine in a Long-term Psychiatric Unit.

Methods: A retrospective observational study was conducted with a sample of women of our long-term psychiatric care unit who had been treated with clozapine.

Carrier-Density Control of the SrTiO3 (001) Surface 2D Electron Gas studied by ARPES.

The origin of the 2D electron gas (2DEG)stabilized at the bare surface of SrTiO3 (001) is investigated. Using high-resolution angle-resolved photoemission and core-level spectroscopy, it is shown conclusively that this 2DEG arises from light-induced oxygen vacancies. The dominant mechanism driving vacancy formation is identified, allowing unprecedented control over the 2DEG carrier density.

Focal segmental glomerulosclerosis due to a relapsing non-Hodgkin's lymphoma diagnosed by positron emission tomography.

Glomerulonephritis rarely appears associated with Hodgkin's disease or non-Hodgkin's lymphoma (NHL). We present a patient with a relapse of a non-Hodgkin's lymphoma which first presented as nephrotic syndrome due to focal segmental glomerulosclerosis (FSGS). This case report discusses the unusual association of non-Hodgkin's lymphoma and focal segmental glomerulosclerosis, as well as the crucial role of positron emission tomography in detecting the relapsing lymphoma.

Long daily hemodialysis sessions correct systemic complications of oxalosis prior to combined liver-kidney transplantation: case report.

An 18-year-old woman diagnosed with piridoxine-resistent primary hyperoxaluria type 1 (PH-1) and progressive renal insufficiency complicated with acute renal failure of obstructive origin who developed systemic oxalosis affecting the heart (cardiomyopathy), the skin (cutaneous ulcers) and vascular system (lower limb ischemia, as well as pulmonary and cerebral microcirculatory blockage resulting in pulmonary hemorrhage and tonic-clonic general seizures. As conventional hemodialysis (HD) or peritoneal dialysis (PD) are unable to eliminate enough oxalate to avoid a continuous positive balance, long daily sessions (6-7 h) of high-flux hemodialysis (highly permeable polyamide membrane of 2.1 m2) for 67 consecutive days normalized blood oxalate levels and reversed the systemic complications secondary to the calcium oxalate crystals deposit.

Prevalence of left ventricular hypertrophy in patients with mild hypertension in primary care: impact of echocardiography on cardiovascular risk stratification.

Background: Left ventricular hypertrophy (LVH) is an important predictor of cardiovascular risk, and its detection contributes to risk stratification. The aims of the present study were to estimate the prevalence of echocardiographic LVH and to evaluate the influence of echocardiography (ECHO) on cardiovascular risk stratification in hypertensive patients presenting in primary care.

Methods: In this cross-sectional study, 250 patients recently diagnosed with mild hypertension underwent clinical evaluation including electrocardiography (ECG), microalbuminuria measurement, 24-h blood pressure monitoring and ECHO.
