Methods of materials preparation are examined, presenting the main advantages or disadvantages of each one based on their potential uses. Finally, a review of the main characterization techniques and methods used to study polymer based antibacterial materials is carried out, including the use of single force cell spectroscopy, contact angle measurements and surface roughness to evaluate the role of the physicochemical properties and the micro or nanostructure in antibacterial behavior of the materials.The fall armyworm (FAW) has recently invaded and become an important pest of maize in Africa causing yield losses reaching up to a third of maize annual production. The present study evaluated different aspects of resistance of six maize cultivars, cropped by farmers in Kenya, to FAW larvae feeding under laboratory and field conditions. We assessed the arrestment and feeding of FAW neonate larvae in no-choice and choice experiments, development of larvae-pupae, food assimilation under laboratory conditions and plant damage in a field experiment. We did not find complete resistance to FAW feeding in the evaluated maize cultivars, but we detected differences in acceptance and preference when FAW larvae were given a choice between certain cultivars. Moreover, the smallest pupal weight and the lowest growth index were found on 'SC Duma 43' leaves, which suggests an effect of antibiosis of this maize hybrid against FAW larvae. In contrast, the highest growth index was recorded on 'Rachar' and the greatest pupal weight was found on 'Nyamula' and 'Rachar'. The density of trichomes on the leaves of these maize cultivars seems not to be directly related to the preference of neonates for feeding. Plant damage scores were not statistically different between cultivars in the field neither under natural nor artificial infestation. However, plant damage scores in 'Nyamula' and 'Jowi' tended to be lower in the two last samplings of the season compared to the two initial samplings under artificial infestation. Our study provides insight into FAW larval preferences and performance on some African maize cultivars, showing that there are differences between cultivars in these variables; but high levels of resistance to larvae feeding were not found.Background and objectives There has been an increasing interest in the role of inflammation in thrombosis complications in chronic heart failure (HF) patients. The incidence of thrombosis in HF has been shown to be the highest in patients classified as NYHA IV (New York Heart association). It is stated that inflammation is regulated by platelet-induced activation of blood leukocytes. We aimed to compare the platelet and cell count readings in chronic HF with reduced ejection fraction (HFrEF) patients according to NYHA functional class and to evaluate the correlation between those readings. Materials and methods A total of 185 patients were examined. The results of heart echoscopy (TEE) testing; fibrinogen, N-terminal pro b-type natriuretic peptide (NT-proBNP), C reactive protein (CRP), and cortisol concentrations; complete blood counts; and a 6 min walking test were assessed and platelet aggregation was determined. Results Mean platelet volume (MPV) increased with deterioration of a patient's state (p less tin chronic HFrEF.Sunset yellow (SY) at prescribed concentrations has been approved by regulatory authorities in several countries as an additive dye in the food, beverage, cosmetic, and pharmaceutical industries. However, there are some reports that it may cause several health problems. The aim of this study is to evaluate embryotoxic effects of SY on liver and kidney in chick embryos. Babcock white Leghorn eggs were randomly divided into four groups. Non-treated eggs served as control group. The eggs in groups SY200, SY1000, and SY2000 were treated with a single injection of 200, 1000, and 2000 ng SY into the air sac just before incubation. The developmental stages of embryos were determined on the 10th, 13th, 16th, and 21st days of incubation. Samples of the liver and kidney were taken and routine histological procedures were performed. The highest relative embryo weight was seen in all SY treated groups on the 16th day of incubation. Necrosis of some hepatocytes and cytoplasmic degenerations were observed in all SY groups in the liver. There were degenerated or destructed renal cortex structures and necrosis in the kidney. The cell's nuclear areas and diameters of renal cortex structures were different in all SY groups compared to the control group (p less then 0.05). It was concluded that in ovo administered SY has many unfavorable effects on liver and kidney in chick embryos. The results obtained in this study suggest that it may be advisable to re-assess safety levels of SY in many industries.
  It has been reported that the occurrence of immune-related adverse events (irAEs) in oncological patients treated with immune-checkpoint inhibitors (ICIs) may be associated with favorable clinical outcome. We reported the clinical correlation between irAEs and the efficacy of ICIs in a real-world cohort of metastatic renal cell cancer (mRCC) patients.
 
  We retrospectively evaluated 43 patients with mRCC who were treated with nivolumab or with nivolumab plus ipilimumab. We considered seven specific classes of irAEs including pulmonary, hepatic, gastrointestinal, cutaneous, endocrine, rheumatological, and renal manifestations. We assessed progression-free survival (PFS) of specific irAEs classes compared to the no-irAEs group.
 
  Twenty-nine out of 43 patients (67.4%) experienced a total of 49 irAEs registered. The most frequent irAE was thyroid dysfunction (
  = 14). The median PFS after the beginning of therapy was significantly longer in patients with thyroid dysfunction and cutaneous reactions.  https://www.selleckchem.com/products/acy-775.html  In multivariate analysis, thyroid dysfunction was an independent factor for favorable outcome [HR 0.29 (95% CI 0.11-0.77) 
  = 0.013]. Moreover, experiencing ≥2 irAEs in the same patient correlated in multivariate analysis with better outcome compared with none/one irAE [HR 0.33 (95% CI 0.13-0.84) 
  = 0.020].
 
  This retrospective study suggests an association between specific irAES (thyroid dysfunction and skin reaction) and efficacy of ICIs in metastatic RCC. Notably, multiple irAEs in a single patient were associated with better tumor response.
