Viral infections cause life-threatening diseases in millions of people worldwide every year and there is urgent need for new effective antiviral drugs. Hybridization of two chemically diverse compounds into a new bioactive effector product is a successful concept to improve the hybrid drug's properties compared to its parent compounds. In this study, (iso)quinoline-artemisinin hybrids, obtained via copper-catalyzed azide-alkyne cycloaddition (CuAAC) or organocatalyzed click reactions (in organic solvents or in the presence of water), were analyzed in vitro for the first time for their inhibitory activity against human cytomegalovirus (HCMV), as compared with their parent compounds and the reference drug ganciclovir. EC50 (HCMV) values were obtained in a range 0.22-1.20 µM, indicating highly potent antiviral properties in the absence of cytotoxic effects on normal cells (CC50 >100 µM). The most active hybrid 1 (EC50 = 0.22 µM) is 25 times more potent than its parent compound artesunic acid (EC50 = 5.41 µM) and 12 times more efficient than the standard drug ganciclovir (EC50 = 2.6 µM). Interestingly, hybrid 1 shows also inhibitory activity against hepatitis B virus in vitro (EC50 (HBeAg) = 2.57 µM).Aim The purpose of this retrospective study was to perform an evaluation of postoperative positional changes of the condyle and mandibular function after bilateral sagittal split osteotomy (BSSO) with manual proximal segment positioning. Patients 45 patients were divided into the 2 groups ‒ G1 (advancement ‒ 14 patients) and G2 (setback - 31 patients). Rigid internal fixation screws were utilized in all cases. Inclusion criteria were only BSSO, no TMJ symptoms preoperatively and age 18 or older. Results The differences between pre- and postoperative condyle position were evaluated using measurements taken from preoperative CT scans and compared to CT scans made a minimum of 6 months postoperatively. The positional changes in both the axial and sagittal planes were measured and compared. The recovery of mandibular function was evaluated by measuring maximal interincisal opening (MIO). The results revealed that condylar positional changes after BSSO in both groups were minimal and not significantly different for all three dimensions measured. The recovery of mandibular function was faster in the group G2 than in the group G1. Mandibular function reached almost preoperative level in 6-12 months postoperatively in both groups. Conclusion The results demonstrated that following BSSO, only insignificant condylar displacement and functional changes occurred within 6 to 12 months postoperatively (Tab. 4, Fig. 2, Ref. 47).Introduction Increasing the knowledgebase of anopheline larval ecology could enable targeted deployment of malaria control efforts and consequently reduce costs of implementation. In Malawi, there exists a knowledge gap in anopheline larval ecology and, therefore, basis for targeted deployment of larval source management (LSM) for malaria control, specifically larvicides. We set out to characterize anopheline larval habitats in the Majete area of Malawi on the basis of habitat ecology and anopheline larval productivity to create a basis for larval control initiatives in the country. Methods Longitudinal surveys were conducted in randomly selected larval habitats over a period of fifteen months in Chikwawa district, southern Malawi. Biotic and abiotic parameters of the habitats were modelled to determine their effect on the occurrence and densities of anopheline larvae. Results Seventy aquatic habitats were individually visited between 1-7 times over the study period. A total of 5,123 immature mosquitoes (3,35larval densities in aquatic habitats in Majete, Malawi. While the most productive aquatic habitats should be prioritised, for the most effective control of vectors in the area all available aquatic habitats should be targeted, even those that are not characterized by the identified predictors. Further research is needed to determine whether targeted LSM would be cost-effective when habitat characterisation is included in cost analyses and to establish what methods would make the characterisation of habitats easier.Background The association between body mass index (BMI) status and childhood asthma control is not well understood. The aim of this study was to explore the association between BMI status and childhood asthma control. Methods Two hundred forty-two children, aged 6-11 years, with asthma were included. The outcome variables were asthma control levels assessed by the Chinese version of the childhood asthma control test (C-ACT), asthma-related hospitalizations or emergency department (ED) visits in the past 12 months, and forced expiratory volume in 1 second (FEV1) as a percentage of the predicted value. The associations between BMI status (underweight, overweight, or obese, relative to normal weight) and the three outcome variables were estimated by ordinal logistic regression, binary logistic regression, and multiple linear regression analyses. Results No significant association was found between BMI status and asthma control levels assessed by C-ACT, and between BMI status and asthma-related hospitalizations or ED visits in the past 12 months, after adjustment for age, sex, father's education level, mother's education level, per capita family monthly income, medical insurance, passive smoking, allergic rhinitis, course of disease, and medication compliance. A significant association between underweight and FEV1 as a percentage of the predicted value was found after adjustment for the above covariates. However, no significant association between overweight or obese and FEV1 as a percentage of the predicted value was found. Conclusions This study shows that BMI status may not be associated with childhood asthma control. Given the inconsistency in current evidence, more studies are needed in the future to investigate this association.Calcium alginate (CaAlg) beads were prepared using ultrasound for use in the removal of lead from natural and wastewaters by ion exchange. Ultrasound was applied in a batch mode with an ultrasonic bath or in a flow mode using an ultrasonic clamp-on device. MYCMI-6 in vitro For comparison purposes the synthesis was performed in batch mode in the absence of the ultrasound. The beads prepared using ultrasound showed a greater ion exchange capability which could be ascribed to a larger specific surface area as a result of surface roughening induced by cavitation. Scanning Electron Microscopy (SEM) images revealed that the roughening was in the form of corrugation for the product with the best ion exchange capability obtained in the flow process where preformed CaAlg droplets were subjected to ultrasound during the setting process. These beads performed 11% better for lead removal than those synthesized in the absence of ultrasound.
