#1
Volker Tronnier
Neuromodulatory techniques have replaced the earlier performed neurolesional procedures to treat chronic pain syndromes with only a few exceptions. Nevertheless these procedures are invasive with respective risks and complications and therefore conservative physical, psychological pharmacological as well as interventional treatments should be performed first. Because this therapy is costly, the indication has to be proven carefully with a strict patient selection and also the long-term results have to be considered...

#2
Bernhard Widder
The majority of medicolegal assessments in claimed psychic sequelae after accidents concerns minor traumatic events. In this case, the focus is on three questions: Was the event appropriate to cause a traumatic disturbance according to current psychiatric classification systems (especially current DSM-5)? Which psychical or physical initial injury can be proven beyond reasonable doubt ("full proof") according to German law? What is the impact of personality characteristics and competing life events in the development and maintenance of the mental disorder? Causality between mental disorders and minor traumatic events is to be confirmed especially in the case of persistent physical accident sequelae, but attention has to be paid to the differences in the various legal requirements...

Human papillomavirus (HPV)-driven oropharyngeal cancers (OPCs) represent an increasing proportion of head and neck cancers that could become, in the next few decades, a public health problem in certain western countries. This significant epidemiological change strongly calls for preventive measures. Prophylactic HPV vaccination and screening programmes for early identification and treatment of premalignant lesions are currently being used to reduce the incidence of uterine cervical cancer, which is the paradigm of HPV-driven malignancy...

Combinatorial approaches in directed evolution were proven to be more efficient for exploring sequence space and innovating the function of protein. We presented modular assembly of secondary structures (MASS) for constructing a combinatorial library. In this approach, secondary structure elements were extracted from natural existing proteins, the common linkers were flanking secondary structure elements, then digested by Hinf I restriction endonuclease that was used in the construction of combinatorial library for the first time...

The use of nitrous oxide (N2O) for labor and birth has very recently emerged as a viable modality in the United States, despite a long history of use in Canada and Europe. Usually associated with dental procedures, there are significant differences between dental and parturition utility, efficacy, and staff exposure. In addition to using it for pain relief and anxiolysis, those centers utilizing it have noted it to be multipurpose and useful for such situations as: external cephalic version, manual removal of placenta, intravenous starts, during placement of urinary catheters and intracervical Foley bulbs...

Aims Cardiovascular fixed-dose combination pills, or polypills, may help address the widespread lack of access and adherence to proven medicines. Initiation of polypill-based care typically entails switching from current separately taken medications. Given the heterogeneity in usual care, there is interest in the impact of polypill treatment across different patterns of prior medication regimen. Methods A total of 2004 participants with established cardiovascular disease or estimated 5-year cardiovascular risk of over 15% were randomised to polypill-based treatment (aspirin 75 mg, simvastatin 40 mg, lisinopril 10 mg and either atenolol 50 mg or hydrochlorothiazide 12...

Cell-penetrating peptides (CPPs), have been proven as important drug delivery vehicles, demonstrating the potential as therapeutic candidates. The last decade has witnessed a rapid growth in CPP-based research. Recently, many computational efforts have been made to develop machine learning based methods for identifying CPPs. Although much progress has been made, existing methods still suffer low feature representation capability that limits further performance improvement. In this study, we propose a novel predictor called CPPred-RF, in which we integrate multiple sequence-based feature descriptors to sufficiently explore distinct information embedded in CPPs, employ a well-established feature selection technique to improve the feature representation, and at the first time, construct a 2-layer prediction framework based on the random forest algorithm...

Short tandem repeats (STRs) are highly variable elements that play a pivotal role in multiple genetic diseases, population genetics applications, and forensic casework. However, it has proven problematic to genotype STRs from high-throughput sequencing data. Here, we describe HipSTR, a novel haplotype-based method for robustly genotyping and phasing STRs from Illumina sequencing data, and we report a genome-wide analysis and validation of de novo STR mutations.

Three-dimensional (3D) cell cultures represent advances in the way in which cells are grown in vitro, and they are gaining ground for a variety of applications. Advantages of 3D systems include reliable and realistic study endpoints. Cells grown in 3D conditions mimic in vivo conditions to an extent that is not possible with traditional 2D cell-culture methods. One major area in which 3D cell cultures have proven to make a difference is with drug discovery. The facets taken advantage of for drug discovery are the cells' complex microenvironment, including the production of extracellular matrices, altered gene expressions and their protein products, drug metabolism, and susceptibility to drugs when compared to 2D cultures...

INTRODUCTION: Acute myeloid leukemia (AML) rarely involves the central nervous system (CNS). Little is known about the clinical course in adult AML patients since most studies examined pediatric patients. Therefore, this study analyzed the data of patients treated in three prospective trials of the "Study Alliance Leukemia" (SAL) study group for CNS involvement. METHODS: In all, 3,261 AML patients included in the prospective AML96, AML2003, and AML60+ trials of the SAL study group were analyzed...

Long noncoding RNA (lncRNA) has been proven to be involved in many biological processes in ovarian cancer (OC). However, the mechanism still remains unknown. In this study, we screened significantly downregulated NBAT-1, which has been proven to play a significant role in breast cancer, clear cell renal cell carcinoma, and neuroblastoma, but not in OC, in two independent datasets with relatively more samples (GSE18520 and GSE38666) from Gene Expression Omnibus. We found that lncRNA NBAT-1 was obviously downregulated in OC tissue compared to normal ovarian tissue (P<0...
