AIM A scoping study to give an insight into progression for health care assistants. METHOD Semistructured telephone interviews were used to gain the views of strategic health authorities and workforce development directorates on HCA progression. These were compared with the Department of Health's figures on HCA progression. RESULTS The main findings indicate that a new definition for the ro...
A series of polymethoxylated-pyrazoline benzene sulfonamides were synthesized, investigated for their cytotoxic activities on tumor and non-tumor cell lines and inhibitory effects on carbonic anhydrase isoenzymes (hCA I and hCA II). Although tumor selectivity (TS) of the compounds were less than the reference compounds 5-Fluorouracil and Melphalan, trimethoxy derivatives 4, 5, and 6 were more s...
The hybrid cellular automaton (HCA) algorithm was inspired by the structural adaptation of bones to their ever changing mechanical environment. This methodology has been shown to be an effective topology synthesis tool. In previous work, it has been observed that the convergence of the HCA methodology is affected by parameters of the algorithm. As a result, questions have been raised regarding ...
Objective: This study aimed to systematically review the gadoxetic acid-enhanced magnetic resonance imaging (Gd-EOB-DTPA-MRI) findings of hepatocellular adenoma (HCA), especially focusing on the diagnostic value of low signal intensity (SI) in the hepatocyte-phase (HBP) for differentiating HCA from focal nodular hyperplasia (FNH). Methods: A thorough literature search was conducted in PubMed, E...
BACKGROUND Healthcare aides (HCAs) are the primary caregivers for vulnerable older persons. They have many titles and are largely unregulated, which contributes to their relative invisibility. The objective of this scoping review was to evaluate the breadth and depth of the HCA workforce literature. METHODS We conducted a search of seven online bibliographic databases. Studies were included i...
Every issue raised by the current investigation into the business practices of Columbia/HCA serves as a signpost for the progress and problems inherent in market-driven health care reform. Actions against Columbia/HCA by regulators reveal deeply rooted resistance to the profit-motivated reforms embodied in the company’s philosophy: the public’s reluctance to accept necessary reductions in exces...
The phytocomponent p-hydroxycinnamic acid (HCA) has been shown to have inhibitory effects on bone-resorbing factor-stimulated bone resorption in rat femoral tissues in vitro. The effects of HCA on osteoclast-like cell formation in mouse bone marrow cultures in vitro were investigated. The bone marrow cells were cultured for 7 days in alpha-minimal essential medium containing a bone-resorbing ag...
With the growing numbers of nanomaterials (NMs), there is a great demand for rapid and reliable ways of testing NM safety-preferably using in vitro approaches, to avoid the ethical dilemmas associated with animal research. Data are needed for developing intelligent testing strategies for risk assessment of NMs, based on grouping and read-across approaches. The adoption of high throughput screen...
The phytocomponent p-hydroxycinnamic acid (HCA) has been shown to have a stimulatory effect on bone formation and an inhibitory effect on bone resorption in rat femoral tissues in vitro. The preventive effect of HCA on bone loss induced in streptozotocin (STZ)-diabetic rats was investigated in vivo. Rats received a single subcutaneous administration of STZ (6.0 mg/100 g body weight), and then t...
the multivariate calibration method, partial least square regression (pls) was applied for thesimultaneous spectrophotometric determination of lidocaine (lid) and hydrocortisone acetate(hca) in their mixtures. the parameters of chemometric technique were optimized and theproposed method was validated with synthetic samples and applied to analyze these drugs inpharmaceutical products with good a...
