Respiratory system conditions as well as allergic sensitization inside swine collie breeders: any population-based cross-sectional research.
Objective To describe the prevalence of pulmonary arterial hypertension (PAH)-associated gene mutations, and other genetic characteristics in a national cohort of children with PAH from the Dutch National registry and to explore genotype-phenotype associations and outcomes. Study design Children (n = 70) diagnosed with idiopathic PAH (IPAH), heritable PAH (HPAH), PAH associated with congenital heart disease (CHD) with coincidental shunt (PAH-CHD group 3), PAH after closure of a cardiac shunt (PAH-CHD group 4), or PAH associated with other non-cardiac conditions were enrolled. Targeted next-generation sequencing was performed on PAH-associated genes (BMPR2, ACVRL1, EIF2AK4, CAV1, ENG, KCNK3, SMAD9 and TBX4). Also, children were tested for specific genetic disorders in case of clinical suspicion. Additionally, children were tested for copy number variations (CNVs). Results Nineteen children (27%) had a PAH-associated gene mutation/variant BMPR2 n=7, TBX4 n=8, ACVRL1 n=1, KCNK3 n=1, EIF2AK4 n=2. Twelve children (17%) had a genetic disorder with an established association with PAH (including trisomy 21 and Cobalamin C deficiency). In another 16 children (23%) genetic disorders without an established association with PAH were identified (including Noonan syndrome, Beals syndrome and various CNVs). Survival rates differed between groups and was most favorable in TBX4 variant carriers. Conclusions Children with PAH show a high prevalence of genetic disorders, not restricted to established PAH-associated genes. Genetic architecture could play a role in risk-stratified care management in pediatric PAH.Background The goal of this study was to investigate the association between bactericidal permeability increasing (BPI)-antineutrophil cytoplasmic antibody (ANCA) protein levels and primary Sjogren's syndrome (pSS) with lung involvement, as well as the potential diagnostic performance of BPI-ANCA. Methods The levels of BPI-ANCA in pSS patients with (n = 36) and without (n = 85) lung involvement were measured using a commercial ELISA kit. Serological biomarkers and cytokines were measured in these patients as well. Lung involvement was determined by high-resolution computed tomography (HRCT) and/or clinical symptoms. The diagnostic performance of lung involvement was determined by receiver operating characteristic (ROC) curves. Results The percentage of neutrophils (NEUT%), neutrophil-lymphocyte ratio (NLR), erythrocyte sedimentation rate (ESR), and the levels of BPI-ANCA, C-reactive protein (CRP), interleukin-2 (IL-2) and IL-6 exhibited an upward trend, while the percentage of lymphocytes (LYMP%) and albumin (ALB) level exhibited a downward trend in the lung involvement group. The combination of BPI-ANCA, NEUT% and ALB significantly increased the area under the ROC curve (AUC) to 0.837 (95% confidence interval 0.742-0.907, sensitivity 82.14%, specificity 81.36%, P less then 0.001). Conclusions Increased BPI-ANCA was found in pSS patients with lung involvement and was associated with inflammation. A combination of BPI-ANCA, NEUT% and ALB had the best AUC, and may serve as anadjunct to distinguish between pSS patients with and without lung involvement.This study provides a comprehensive assessment of the parameters of the spherical crystallization process and their impact on the micromeritic properties of lactose spherical agglomerates. A recently introduced definitive screening design was used to study various process parameters, with particular focus on building predictive models. The parameters included were lactose solution concentration; volume ratio between the antisolvent and the whole crystallization system; crystallization system temperature; velocity of the addition of the lactose water solution; agitation velocity; and agitation time after whole addition of the lactose solution. Their effects on process yield, particle size parameters D10, D50 and D90, particle size distribution, morphological properties (roundness, solidity) and Hausner ratio were studied. Active effects were identified for all of these responses, with quadratic and interaction effects included. Lactose concentration, volume ratio, crystallization system temperature, and agitation velocity were identified as critical process parameters. For every response, a statistical model was built, where those for Hausner ratio, yield and roundness provided the best predictive performances. Based on these models, D10 and yield were successfully optimized. Definitive screening design proved as useful especially in the screening phase; however, additional experiments are needed to build models with high predictive power for all of these responses.A review of work on pharmaceutical molecular materials studied under high pressure was carried out. The behavior of the crystallographic structure of these materials is observed under high pressure thanks to X-ray diffraction laboratory, synchrotron experiments or Raman spectroscopy. In particular, the highlighting of phase transitions and the discovery of new crystallographic forms are an important application of these methods. Works performed from the last two decades shows that two ways are mainly used direct compression of powders or single crystals and crystallization under high pressure in different solvents. The evolution of the cell volumes and lattice parameters of different compounds have been observed with direct compression experiments of the order of few GPa to few tens of GPa. On few compounds the discovery of new polymorphic forms is highlighted. High pressure crystallization experiments generally require lower pressure ranges, on the order of few hundred to few GPa. For numerous pharmaceutical molecules, new polymorphs but also salts, solvates, hydrates or co-crystals can be obtained. It depends on the solvents and pressure ranges chosen. 5'-N-Ethylcarboxamidoadenosine mw It shows the possibility to select the desired crystallographic form of a given active principle by a judicious choice of these parameters.Here we have reported whole-body disposition of wild-type IgG and FcRn non-binding IgG in mice, determined using Enzyme-Linked Immunosorbent Assay (ELISA). The disposition data generated using ELISA are compared with previously published biodistribution data generated using radiolabelled IgG. In addition, we introduce a novel concept of ABCIS values, which are defined as percentage ratios of tissue interstitial and plasma AUC values. These values can help in predicting tissue interstitial concentrations of monoclonal antibodies (mAbs) based on the plasma concentrations. Tissue interstitial concentrations derived from our study are also compared with previously reported values measured using microdialysis or centrifugation method. Lastly, the new set of biodistribution data generated using ELISA are used to refine the PBPK model for mAbs.
