#1
Markus Hoopmann, Karl Oliver Kagan
The midsagittal view of the fetal profile is essential in first trimester screening at 11 + 0 to 13 + 6 weeks of gestation. None of the standard sections in prenatal medicine is as well defined and undergoes such a strong quality assurance program. These requirements were recently challenged by the introduction of cell-free DNA screening. The fetal profile view was previously only needed for the appropriate measurement of the fetal nuchal translucency thickness. In recent years, it became evident that there are many more anomalies or markers for fetal defects that can be seen in this section such as spina bifida, facial clefts or retrognathia...

BACKGROUND: Bertolotti's syndrome is a spinal disorder characterized by abnormal enlargement of the transverse process of the most caudal lumbar vertebra. The L5 transverse process may be enlarged either unilaterally or bilaterally and may articulate or fuse with the sacrum or ilium. Pseudoarticulation between the transverse process of the L5 and the alar of the sacrum can cause buttock pain and leg pain. In addition, the L4 exiting nerve root could be compressed by an enlarged L5 transverse process...

BACKGROUND: The KAST (Kiva Safety and Efficacy) investigation device exempt (IDE) study indicated that the majority of patients responded equally well to vertebral augmentation using either an implant-based approach or balloon kyphoplasty (BK). Additional investigation has suggested that a subset of patients may benefit further by avoiding repeated readmissions due to serious adverse events (SAEs) if they receive one vertebral augmentation approach over another. OBJECTIVES: The primary aim was to assess the effect of 2 different augmentation procedures on readmission rates for SAEs...

Jacqui Clark, Jo Nijs, Gillian Yeowell, Peter Charles Goodwin
BACKGROUND: Altered central pain modulation is the predominant pain mechanism in a proportion of chronic musculoskeletal pain disorders and is associated with poor outcomes. Although existing studies predict poor outcomes such as persistent pain and disability, to date there is little consensus on what factors specifically predict altered central pain modulation. OBJECTIVES: To review the existing literature on the predictive factors specifically for altered central pain modulation in musculoskeletal pain populations...

BACKGROUND: Discogenic low back is a distinct clinic entity characterized by pain arising from a damaged disc. The diagnosis is clouded by the controversy surrounding discography. The treatment options are limited, with unsatisfactory results from both conservative treatment and surgery. Multiple interventional therapies have been developed to treat discogenic pain, but most have not yet been validated by high quality studies.The best studied treatment for discogenic pain is the use of heat, which has been labeled as thermal intradiscal procedures (TIPs) by the Centers for Medicare and Medicaid Services (CMS)...

Water quality criteria (WQC) are considered to be an effective management tool for protecting aquatic environments. To derive site-specific WQC for an area, local data based on local species are essential to improve the applicability of WQC derived. Due to the paucity of local fish data available for the development of site-specific WQC for the Liao River, China, four local and widespread fishes (Pseudorasbora parva, Abbottina liaoningensis, Ctenogobius giurinus, and Misgurnus anguillicaudatus) were chosen to test their sensitivities to ammonia, cadmium and nitrobenzene...

The S0→Si, i=1-5 electronic transitions of four 8-(4-aniline)-BODIPY and four 8-(N,N-dimethyl)-BODIPY dyes, differ by number and position of methyl substituents in the BODIPY frame, were investigated theoretically using ab initio the coupled cluster doubles (CC2) and TD-CAM-B3LYP methods. Methyl substituents in the BODIPY frame and the aniline fragment at the meso position disturb energy of local excitations S0→S1, S0→S3, and S0→S4 weakly in comparison with the fully unsubstituted BODIPY molecule. These transitions in experimental spectra form the most long-wave absorption bands at ca...

Stakeholder participation in nature conservation policies and especially in the management of protected areas has gained importance in the last decades. These changes are underlined by democratic principles and the perceived contribution of stakeholder involvement to the effectiveness of conservation management. Evaluating participatory processes is essential to learn about the past and thus increase the quality of future processes. The evaluation can be useful for the organisations responsible for planning and management, stakeholders and policy makers as well...

Dimitrios Tsikas, Erik Hanff
In LC-MS/MS-basedquantitative analysis of biological substances such as the F2-isoprostanes including 8-iso-prostaglandin F2α (i.e., 8-iso-PGF2α) use of stable-isotope labelled analogues at matrix-relevant concentrations is indispensable, enables linearity in relevant concentration ranges, and minimizes matrix effects. The quality of the linearity of calibration curves is an indicator of the analytical reliability of the LC-MS/MS method. Poor linearity is a convincing evidence of lacking analytical reliability...
