This work reports on an optimized procedure to synthesize methylammonium bromide perovskite nanoparticles. The ligand-assisted precipitation synthetic pathway for preparing nanoparticles is a cost-effective and promising method due to its ease of scalability, affordable equipment requirements and convenient operational temperatures. Nevertheless, there are several parameters that influence the resulting optical properties of the final nanomaterials.

The efficiency of organo-lead halide perovskite-based optoelectronic devices is dramatically lower for amorphous materials compared to highly crystalline ones. Therefore, it is challenging to optimize and scale up the production of large-sized single crystals of perovskite materials. Here, we describe a novel and original approach to preparing lead halide perovskite single crystals by applying microwave radiation during the crystallization.

Background: Evidence for tranexamic acid (TXA) in the pharmacologic management of trauma is largely derived from data in adults. Guidance on the use of TXA in pediatric patients comes from studies evaluating its use in cardiac and orthopedic surgery. There is minimal data describing TXA safety and efficacy in pediatric trauma.

Aim: Intravenous vasodilators are often added to beta-blocking agents to reach blood pressure (BP) goals in aortic dissection. Control of BP using clevidipine has been described in hypertensive emergencies and cardiac surgery but not in aortic dissection. The aim of this study was to compare clevidipine versus sodium nitroprusside (SNP) as adjunct agents to esmolol for BP management in aortic dissection.

The aim of this study was to determine whether the incidence of pneumonia in patients taking clozapine was more frequent compared with those taking risperidone or no atypical antipsychotics at all before admission to a tertiary care medical center. This was a retrospective, case-matched study of 465 general medicine patients over a 25 month period from 1 July 2010 to 31 July 2012. Detailed electronic medical records were analyzed to explore the association between the use of two atypical antipsychotics and incidence of pneumonia.

Article Synopsis
  • Sepsis negatively affects capillary function and oxygen delivery, potentially worsening patient outcomes.
  • Lower levels of immunoglobulin G2 do not contribute to severe flu complications, suggesting other factors may play a role in flu severity.
  • New research indicates that intravenous immunoglobulin may provide brain protection during sepsis by blocking harmful immune responses such as complement activation and apoptosis. *

The need for systematic around-the-clock self-measurements of blood pressure (BP) and heart rate (HR), or preferably for automatic monitoring as the need arises and can be met by inexpensive tools, is illustrated in two case reports. Miniaturized unobtrusive, as yet unavailable instrumentation for the automatic measurement of BP and HR should be a high priority for both government and industry. Automatic ambulatorily functioning monitors already represent great progress, enabling us to introduce the concept of eventually continuous or, as yet, intermittent home ABPM.

Hypertonic saline (HTS) is an osmotic agent that can help patients in the acute phase of severe traumatic brain injury. HTS extracts fluid from swollen cerebral tissue to both control intracranial pressure and diminish the deleterious effects of secondary brain injury. Neuroscience nurses in intensive care and acute care units, who may administer HTS as resuscitation fluid, continuous infusion, or bolus dose, need to be familiar with physiologic actions, potential side effects, and appropriate HTS administration techniques.

Anemia is probably the most widespread syndrome associated with a very wide spectrum of pathological conditions with a different genesis. In malignities and their treatment it is one of the very serious complications the impact of which is manifested in particular in the state of the circulation. Thus anemia can cause deterioration of primary cardiac and cardiovascular complications which develop either as a result of the malignant disease or as a result of its treatment by cardiotoxic drugs.

Twenty-two patients with chronic ischaemic heart disease (IHD) and reversible myocardial ischaemia after a load as recorded by single photon emission computed tomography (SPECT) participated in an eight-week rehabilitation programme. Before exercise their efficiency was tested by spiroergometric examinatin and the patients were randomized into two groups. Group A (10 patients) took exercise at the level of the anaerobic threshold (high intensity training), group B (12 patients) trained at the level of the 60 % anaerobic threshold (low intensity training).

INTRODUCTION: Melatonin (MEL), a pineal hormone, is well known as a potent antioxidant in a variety of ischemia-reperfusion models. Recent studies have assumed a pivotal role of reactive oxygen species (ROS) in the development of apoptosis. There are few pieces of information concerning a possible protective role of MEL against apoptosis in ischemia-reperfusion injury of myocardium.

Regular physical activity can have a favourable impact on other risk factors of ischaemic heart disease (IHD) and associated diabetes (DM), such as obesity, hypertension, dyslipidaemia, insulin resistance and others. This important part of treatment of diabetes is frequently difficult to implement because of the lack of willingness ("adherence") of type 2 diabetics to practice regular exercise, and unequivocal data are lacking on the intensity of exercise which will influence effectively these risk factors and be at the same time safe, readily available and psychologically acceptable. The objective of the work was to find out whether walking, i.

The authors investigated by echocardiography changes of left ventricular function in 79 patients with non-Hodgkin lymphoma or Hodgkin's disease who were treated by chemotherapy containing doxorubicin. In 22% patients they diagnosed during treatment a significant gradual decline of the left ventricular ejection fraction (change > 10% or a drop of EF below 50%) after a cumulative dose of 185 +/- 52 mg/m2 doxorubicin (median 200 mg/m2). Changes of the ejection fraction were at the expense of an increasing endsystolic left ventricular volume.

Appropriate use of various pharmacologic agents involves not only awareness of therapeutic indications and side effects but also familiarity with clinical use and timing of blood level monitoring. The effective as well as the toxic level of antiepileptic drugs varies widely among patients, so the patient's response is more important than the serum drug level. These agents may interact with other disease states, other drugs, and even other antiepileptic agents.
