This study was aimed at preparing and characterising kojic acid nanostructured lipid carriers (KA-NLCs) for delivery to skin. KA-NLCs were prepared using high-speed homogenization followed by ultra-probe sonication method. KA-NLCs were optimized by glyceryl mono-stearate (GMS) and cholesterol (Chol) as solid lipid excipients, oleic acid (OA) as liquid lipid excipient, span 60 (SP 60) and Tween 20 (Tw 20) as co-emulsifiers. For optimized formulation (KA-NLC3), values of particle size, encapsulation efficiency, drug loading, polydispersity index (PDI) and zeta potential (ZP) were found to be 172.9 ± 7.1 nm, 76.4 ± 0.1%, 17.6 ± 1.3%, 0.3 ± 0.1 and -39.1 ± 2.7 mV, respectively. KA-NLC3 was stable at 4 °C and 25 for 3 months. TEM image confirmed these results. ATR-FTIR, DSC and PXRD results indicated suitable entrapment of KA in NLCs without any chemical interaction. The release profile of KA-NLC3 followed a sustained pattern. KA-NLC3 has potent tyrosinase inhibitory activity in comparison with pure KA. Nanoparticles showed a higher antioxidant activity than pure KA. The results of the ex vivo and in vitro percutaneous absorption showed that KA-NLC3 improved percutaneous delivery of KA. Concentrations below 250 μg/mL were determined as suitable concentrations for KA-NLC3. It seems to be biocompatible formulation for the cosmetics aims.
Pancreatic cancer is often associated with cachexia. It had been reported that eicosapentaenoic acid (EPA) improve cachexia. This study aimed to evaluate the efficacy and safety of gemcitabine with an EPA-enriched oral supplement in patients with advanced pancreatic cancer.
This open-label phase II study consisted of patients (pts) who were randomly categorized into the EPA group (1,000 mg/m
gemcitabine was administered on day 1, 8, and 15, every 4 weeks while an EPA-enriched oral supplement (prosure®, EPA 1.056 mg per pack) was taken daily at the maximum of two packs or the gemcitabine monotherapy group with an allocation ratio of 21. The primary endpoint was the evaluation of the 1-year survival estimating 10% addition.
Randomized 68 pts were examined (EPA 45, gemcitabine 23). The 1-year survival probability of the EPA group was 35% while the gemcitabine group was 19%. The median survival times were 8.2 and 9.7 mo, respectively. The hazard ratio for EPA group was 0.79 [95% CI 0.46-1.37]; (
= 0.40). The toxicities were mild and insignificant in both groups. More beneficial effects of EPA in survival were observed in men, pancreatic body-tail and low C-reactive protein patients.
An EPA-enriched oral supplement may be effective in advanced pancreatic cancer.

The DESCANT (Dementia Early Stage Cognitive Aids New Trial) intervention provided a personalised care package designed to improve the cognitive abilities, function and well-being of people with early-stage dementia and their carers, by providing a range of memory aids, together with appropriate training and support. This sub-study aimed to assess implementation and identify contextual factors potentially associated with participant outcomes.
A mixed-methods approach was adopted alongside the pragmatic randomised trial. Data were obtained from intervention records and interviews with five dementia support practitioners across seven National Health Service Trusts in England and Wales. A reporting framework was constructed from available literature and data assessed by descriptive statistics and thematic analysis.
Participation and engagement was high with 126 out of 128 participants completing the intervention with packages tailored to individual participants. Misplacing items and poor orientation to dateth dementia and their carers.The pollution and contamination assessment of three heavy metals (Cu, Pb, and Zn) in the topsoil, and common plants (Olea europaea, Prunus persica vulgaris, Ficus carica, Medicago sativa, Zygophyllum album, and Helianthemum kahiricum) were carried out at different distances from a cement plant. This evaluation was based on four evaluation methods Bioconcentration factor, Contamination factor, Geoaccumulation Index and Potential ecological risk factor. The chlorophylls a and b contents were also analyzed. Deutivacaftor ic50 The highest levels of Cu, Zn, and Pb in the topsoil were found close to the cement factory (cluster D), and the lowest values were observed in a distant oasis (cluster H). The lowest chlorophylls values were observed in perennial plants (O. europaea and F. carica) near the cement plant. Zygophyllum album and H. kahiricum showed capability to remove Cu an Zn in contaminated locations, depending on the soil type. The spatialization of the results was essential to the understanding of the potential contribution e also evaluated to establish the effect of the cement plant on the health of plants located nearby.Objective The expression of therapeutic proteins in plant oil body bioreactors has attracted much attention. But its safety is not yet clear. This article determines the risk of safety after using the drug. Methods The oil body-linked oleosin-hEGF microgel emulsion (OBEME) was prepared by mixing the xanthan gum with suitable concentrations in an appropriate proportion. Skin irritation and sensitization reaction were investigated in rats and guinea pigs using OBEME as test article.Results The OBEME did not produce dermal erythema/eschar or oedema responses. The dermal subacute and subchronic toxicity of OBEME were evaluated in accordance with OECD guidelines. Compared with the control group, the basic physical signs, such as weight, feed, drinking, excretion, and behaviour of experimental animals, were not abnormal. In addition, no abnormality was found in haematological parameters, biochemical indexes, relative organ weight, and histopathological observation of organs, and there was no significant difference compared with normal saline treatment group. Therefore, we conclude that OBEME has no toxic effects and is safe and reliable to be used for topical application.
Pulmonary transit time (PTT) from first-pass perfusion imaging is a novel parameter to evaluate hemodynamic congestion by cardiac magnetic resonance (cMR). We sought to evaluate the additional prognostic value of PTT in heart failure with reduced ejection fraction over other well-validated predictors of risk including the Meta-Analysis Global Group in Chronic Heart Failure risk score and ischemic cause.
We prospectively followed 410 patients with chronic heart failure with reduced ejection fraction (61±13 years, left ventricular (LV) ejection fraction 24±7%) who underwent a clinical cMR to assess the prognostic value of PTT for a primary endpoint of overall mortality and secondary composite endpoint of cardiovascular death and heart failure hospitalization. Normal reference values of PTT were evaluated in a population of 40 asymptomatic volunteers free of cardiovascular disease. Results PTT was significantly increased in patients with heart failure with reduced ejection fraction as compared to controls (9±6 beats and 7±2 beats, respectively,
