Comparison of histological and computed tomographic measurements of pig lung bronchi.
2020
Aim Light microscopy is used as template in the evaluation and further development of medical imaging methods. Tissue shrinkage caused by histological processing is known to influence lung tissue dimensions. In diagnosis of COPD, computed tomography (CT) is widely used for automated airway measurement. The aim of this study was to compare histological and computed tomographic measurements of pig lung bronchi. Methods Airway measurements of pig lungs were performed after freezing under controlled inflation pressure in a liquid nitrogen bath. The wall thickness of seven bronchi was measured via Micro-CT and CT using the integral-based method (IBM) and the full-width-at-half-maximum method (FW…
Evolving Risk Factors for Mortality after Lung Transplantation over the Last 10 Years: Insights from a Single-Centre Database
2016
s S233 218 (82%) patients received pooled platelet transfusion -median (IQR) 1(1-2) U. 209 (79%) and 129 (49%) patients received fresh frozen plasma (FFP) and cryoprecipitate with a median (IQR) of 3(2-4) and 0(0-0) U respectively. Conclusion: Rate and volume of transfusion of blood products compare favourably with centres performing surgery off CPB or on ECMO. Requirement for ECMO particularly for BTT, but also PGD is associated with high transfusion requirements.
News from the Underground: What were the most important scientific/clinical take-home messages for juniors?
2014
The ERS International Congress has traditionally been a splendid opportunity to present current updates in clinical respiratory medicine and new research findings. This year’s programme was packed, making it impossible to attend all sessions, but juniors interested in specific fields were there for you to highlight the most important take home messages from the 2014 ERS International Congress in Munich. Amongst the most important news for the clinicians was the publication of a Global Initiative for Asthma (GINA) guidelines update [1]. In the updated guidelines, the heterogeneity of asthma is emphasised, suggesting the need of “4P” (Personalised, Predictive, Preventive and Participatory) tr…

Substituent effects on the stability of the four most stable tautomers of adenine and purine
2019
Substituent effects at the C2-, C8- and N-positions of adenine and purine in their four the most stable tautomers are studied by means of B97D3/aug-cc-pvdz computation applying substituents of varying electronic properties: NO2, CN, CHO, Cl, F, H, Me, OMe, OH and NH2. The substituent effect is characterized by the substituent effect stabilization energy (SESE) and substituent Hammett constant σ. For adenine, SESE is obtained with purine as the reference system. Additionally, for both adenine and purine, SESE characteristics are estimated with benzene, imidazole and amino-pyrimidine as reference systems, when possible, taking into account substitution in topologically equivalent positions. T…
A new pyrazolo pyrimidine derivative inhibitor of cyclooxygenase-2 with anti-angiogenic activity
2003
In a previous study, we reported a new pyrazolo pyrimidine derivative, N(4)-benzyl-N(6),N(6)-dimethyl-1-1(tert-butyl)-1H-pyrazolo[3,4-d]pyrimidine-6,4-diamine (DPP), which inhibited potently cyclooxygenase-2 activity in intact cell assays with minor activity against cyclooxygenase-1 (IC(50)=0.9 nM for cyclooxygenase-2 versus IC(50)=59.6 nM for cyclooxygenase-1). In the present work, this behaviour was confirmed in vivo by using the 24-h zymosan-injected mouse air pouch model (ID(50)=1.36 nM/pouch for prostaglandin E(2) level). We also studied the possible beneficial effect of DPP in the angiogenesis-dependent murine air pouch granuloma and rat paw carrageenan-induced hyperalgesia models. DP…
Long-term phenological data set of multi-taxonomic groups, agrarian activities, and abiotic parameters from Latvia, northern Europe
2021
A phenological data set collected by citizen-scientists from 1970 to 2018 in Latvia is presented, comprising almost 47,000 individual observations of eight taxonomical groups, in addition to agrarian activities and abiotic parameters, covering in total 159 different phenological phases. These original data published offline in annual issues of the Nature and History Calendar (in Latvian, Dabas un vēstures kalendārs) have been digitized, harmonized and geo-referenced. Overall, the possible use of such data is extensive, as phenological data are excellent bioindicators for characterising climate change and can be used for the elaboration of adaptation strategies in agriculture, forestry, and …
