One solutions this problem declining soil fertility would be apply a reasoned organic fertilisation. aim study was evaluate fertilising potential biochar and compost on depleted determine optimal doses best periods application maize. Seven treatments with inputs such as two weeks before sowing, during sowing aft...

Preterm birth produces neonatal respiratory distress syndrome, and dexamethasone (DEX) is administered maternally to induce fetal lung maturation in women at risk of preterm delivery. Antenatal DEX therapy is largely empirical, and administering multiple doses of DEX produces undesirable metabolic and developmental effects in the fetus. It is hypothesized that pharmacokinetic/pharmacodynamic (P...

We studied 60 adult patients to assess if low doses of rocuronium improved conditions for tracheal intubation during induction of anaesthesia with propofol 2.5 mg kg-1 and alfentanil 10 micrograms kg-1. In a double-blind, randomized design, patients were allocated to one of three groups: group P = saline; group R1 = rocuronium 0.1 mg kg-1; and group R3 = rocuronium 0.3 mg kg-1. Intubation condi...

The effect of 406, a novel fusion protein between the N-terminal sequence of the insect insulin-like peptide, bombyxin, human insulin-like growth factor II and mouse interleukin 3 was investigated in its capacity to abrogate the toxic effects of azidothymidine (AZT) in C57BL/6 mice. Mice receiving 2.5 mg/ml AZT in their drinking water were concurrently treated with daily s.c. injections of 14, ...

BACKGROUND Optimal (1ppm) water fluoridation is seen as the most socially equitable way to prevent dental caries, however concerns about the safety of fluoridation are periodically raised. METHODS Research on effects on bone published since the 1991 National Health and Medical Research Council report on water fluoridation was reviewed. RESULTS Thirty-three studies were identified. Adverse e...

This guideline provides an approach to the prevention of acute antineoplastic-induced nausea and vomiting (AINV) in children. It was developed by an international, inter-professional panel using AGREE and CAN-IMPLEMENT methods. Evidence-based interventions that provide optimal AINV control in children receiving antineoplastic agents of high, moderate, low, and minimal emetogenicity are recommen...

Diuretics are used extensively in hospitals and in community medical practice for the management of cardiovascular diseases. They are used frequently as the first line treatment for mild to moderate hypertension and are an integral part of the management of symptomatic heart failure. Although diuretics have been used for several decades, there is still some ambiguity and confusion regarding the...

In this paper proximity effects correction in Electron Beam Lithography by means of an artificial neural network is presented. Supporting approximations to cope with negative doses inherent in Gibbs oscillations which occur from step-like function representation in the Fourier space are introduced. Miller regularization theory as better alternative to Tikhonov one is presented. Optimal filterin...

Positron emission tomography (PET) is an imaging technique that is used to investigate ligand-receptor binding in the living brain and to determine the time course of plasma concentration/receptor occupancy (RO). The purpose of this work was to demonstrate the added value of an adaptive-optimal design for PET scan timings and dose selection over traditional study designs involving fixed or educ...

BACKGROUND Chronic obstructive pulmonary disease is characterized by emphysema, chronic bronchitis, and small airway remodeling. The alveolar destruction associated with emphysema cannot be repaired by current clinical practices. Stem cell therapy has been successfully used in animal models of cigarette smoke- and elastase-induced emphysema. However, the optimal dose of mesenchymal stem cells (...
