Symptoms of chronic idiopathic urticaria (CIU) include relentless itching and painful wheals, which can be physically and psychologically debilitating. Half of all patients with urticaria have angioedema, which is often disfiguring.

The serum concentrations of circulating ICAM-1 (cICAM-1) and soluble receptors for interleukin-2 (sIL-2R) were evaluated on 48 patients with B-cell chronic lymphocytic leukaemia (B-CLL) and on 15 healthy control subjects. The mean +/- SD concentration of cICAM-1 was significantly higher (p < 0.002) in B-CLL patients (407.7 +/- 164.3 ng/ml) than in healthy controls (245.4 +/- 76.7 ng/ml). Patients with progressive disease had higher cICAM-1 levels than patients with "indolent" disease (440.38 +/- 32.3 ng/ml versus 321.36 +/- 14.45 ng/ml; p < 0.0001). Serum levels of cICAM-1 were also significantly higher (p < 0.0002) in patients with advanced stage (III-IV) than in those with early stage (I-II). The increase of cICAM-1 levels was positively correlated to increases of soluble receptors for interleukin-2 (r = 0.9; p < 0.0001). These results seem to show that the measurement of serum levels of cICAM-1 may be an useful tool for monitoring disease activity and tumoral mass in patients with B-CLL. However, further studies are needed to define the functional role of high cICAM-1 levels in the immunological dysregulation of patients with malignancy.

P-Glycoprotein accounts for multidrug resistance in chemotherapy patients and contributes to reduced oral bioavailability and distribution of drugs in the brain. The aim of this study was to establish the qualitative and quantitative structure-activity relationships (QSAR) of flavonoid modulation effects on P-glycoprotein (P-gp)'s function. Using human colorectal adenocarcinoma (HCT15) cells as an in vitro model and fexofenadine as a P-gp substrate, the modulation effects on P-gp at three concentration levels of 22 representative compounds from four flavonoid families were evaluated. Results showed that the modulation (enhanced or inhibitory) effects could be divided into three ranges designated as enhanced (<100%) as compared to the control, low inhibitory (100-217%) and high inhibitory (>217%) as compared to verapamil. An optimal QSAR was constructed for Y1 (adjusted R(2)=0.4798), Y2 (adjusted R(2)=0.6809), and Y3 (adjusted R(2)=0.5902), respectively. This was further confirmed by a highly correlated plot of the predicted percent inhibition against observed values from a respective QSAR equation.

Our results show that cactus pear fruit is a source of bioavailable betalains and suggest that indicaxanthin and betanin may be involved in the observed protection of LDL against ex vivo-induced oxidative modifications.

A rapid high-performance liquid chromatography/positive ion electrospray tandem mass spectrometry method was developed and validated for the quantification of fexofenadine in human plasma using mosapride as internal standard. Following solid-phase extraction, the analytes were separated using an isocratic mobile phase on a reverse-phase column and analyzed by MS/MS in the multiple reaction monitoring mode using the respective [M+H]+ ions, m/z 502/466 for fexofenadine and m/z 422/198 for the IS. The method exhibited a linear dynamic range of 1-500 ng/mL for fexofenadine in human plasma. The lower limit of quantification was 1 ng/mL with a relative standard deviation of less than 5% for fexofenadine. Acceptable precision and accuracy were obtained for concentrations over the standard curve range. The total chromatographic run time of 2 min for each sample made it possible to analyze more than 400 human plasma samples per day. The validated method has been successfully used to analyze human plasma samples for application in pharmacokinetic, bioavailability or bioequivalence studies.
Here, we showed that the secretome of senescent melanoma cells drives basal melanoma cells towards a mesenchymal phenotype, with characteristic of stems illustrated by increased level of the prototype genes FN1, SNAIL, OCT4 and NANOG. This molecular reprogramming leads to an increase in the low-MITF and slow-growing cell population endowed with melanoma-initiating cell features. The secretome of senescent melanoma cells induces a panel of 52 genes, involved in cell movement and cell/cell interaction, among which AXL and ALDH1A3 have been implicated in melanoma development. We found that the secretome of senescent melanoma cells activates the STAT3 pathway and STAT3 inhibition prevents secretome effects, including the acquisition of tumorigenic properties. Collectively, the findings provide insights into how the secretome of melanoma cells entering senescence upon chemotherapy treatments increases the tumorigenicity of naïve melanoma cells by inducing, through STAT3 activation, a melanoma-initiating cell phenotype that could favor chemotherapy resistance and relapse.

The need for new drugs and new targets is particularly compelling in an era that is witnessing an alarming increase of drug resistance in human pathogens. The identification of new targets of known drugs is a promising approach, which has proven successful in several cases. Here, we describe a database that includes information on 5153 putative drug-target pairs for 150 human pathogens derived from available drug-target crystallographic complexes.
Renal colic has been considered predominantly a disease of adults with only occasional cases occurring in the pediatric population. A recent report from a single hospital showed a rise in the number of children with renal colic. Our objective was to examine this in a much larger multihospital database of emergency department (ED) visits.
