Abstract
OBJECTIVE This observational study reports on the postnatal mortality and 30-month outcome of children who underwent fully percutaneous fetoscopic repair of myelomeningocele (MMC) at a single center in Giessen, Germany. METHODS Between October 2010 and August 2014, a total of 72 patients underwent fully percutaneous fetoscopic MMC closure at 21 + 0 to 29 + 1 (mean, 23 + 5) weeks' gestation. Of these, 52 (72%) participated in this study; however, 30-month mortality data are available for all 72 children. Children were examined at four timepoints: shortly after birth and at 3 months, 12 months and 30 months of corrected age. The patients underwent age-specific standardized neurological examinations and assessment of leg movements and ambulation at all timepoints. Cognitive and motor development were assessed using the Bayley Scales of Infant Development, second edition (BSID-II), at 30 months. RESULTS All 72 children survived the intrauterine procedure, however, four (5.6%) infants died postnatally (including two of the 52 comprising the study cohort). Of the 52 patients included in the study, 11.5% were delivered before the 30th week of gestation (mean, 33 + 1 weeks) and, of the survivors, 48.1% had ventriculoperitoneal shunt placement. Of the 50 infants that were alive at 30 months, independent ambulation, without orthosis, was feasible for 46%. At 30 months of follow-up, 46% of children presented with a functional level that was at least two segments better than the anatomical level of the lesion. At 30 months, 70% of the children presented with BSID-II psychomotor development index score of ≥ 70 and 80% with BSID-II mental development index score of ≥ 70. CONCLUSION Intrauterine repair of MMC by percutaneous fetoscopy shows largely similar outcomes to those reported for open repair, with respect to mortality, prematurity, shunt-placement rates, motor and mental development and free ambulation. © 2020 The Authors.

Abstract
Neutron and nuclear beta decay correlation coefficients are linearly sensitive to the exotic scalar and tensor interactions that are not included in the Standard Model (SM). The proposed experiment will measure simultaneously 11 neutron correlation coefficients (a, a, B, D, H, L, N, R, S, U, V) where 7 of them (H, L, N, R, S, U, V) depend on the transverse electron polarization – a quantity that vanishes for the SM weak interaction. The neutron decay correlation coefficients H, L, S, U, V were never attempted experimentally before. The expected ultimate sensitivity of the proposed experiment that currently takes off on the cold neutron beamline PF1B at the Institut Laue-Langevin, Grenoble, France, is comparable to that of the planned electron spectrum shape measurements in neutron and nuclear β decays but offers completely different systematics and additional sensitivity to imaginary parts of the scalar and tensor couplings.

Abstract
Abstract
BACKGROUND
Proton therapy is able to apply high radiation doses to the tumor while sparing healthy tissues by reducing integral dose. Tumor Treating Fields (TTFields) are low intensity (1–3 V/cm) and intermediate frequency (100–300 kHz) alternating electric fields that demonstrated significantly increased survival rates in combination with adjuvant temozolomide (TMZ) in patients with newly diagnosed glioblastoma (ndGBM). Especially in ndGBM IDH wildtype with unmethylated MGMT promotor therapeutic options are restricted. Here, we report on a patient with biopsied ndGBM IDH wildtype with complete radiological response.
MATERIAL AND METHODS
Brain MRI demonstrated an occlusive hydrocephalus and a ring enhancing lesion in the right posterior thalamus in a 42 year old male. Endoscopic third ventriculostomy and stereotactic biopsy of the lesion were performed. Histopathological examination resulted in the diagnosis of a glioblastoma (WHO grade IV), IDH 1 wildtype (R132), IDH 2 wildtype (R172), HIST1H3B/C wildtype, TERT wildtype (C228 and C250), BRAF wildtype, and unmethylated MGMT promotor. In view of the tumor site, resection was not feasible. Consequently, the patient received definitive chemoradiation with TMZ to a total dose of 60Gy incl. proton boost of 5x2 GyRBE. TTFields therapy in combination with TMZ was initiated 4 weeks after completion of chemoradiation, TMZ maintenance was completed per protocol after 6 cycles. TTFields therapy was continued for more than 13 month and to-date the patient is still on therapy.
RESULTS
Current follow up time is 20 months after initial diagnosis with the patient showing a radiological complete response. The first MRI following chemoradiation with TMZ and protons (showed pseudoprogression. After 3 months, the MRI again showed slightly increasing contrast enhancement. However, no clinical symptoms of tumor progression were present. The TTFields usage (compliance) rate, i.e. the rate per time the patient is applying the therapy, of the patient was 86 %. This was well above the independent prognostic threshold of 75 % and supports the feasibility of this approach. A further MRI after 8 weeks showed a stable disease. In a MRI 4 months later, partial response with decreased contrast enhancement plus perfusion restriction in the tumor area was observed. Another MRI after 3 months showed a complete response without perfusion signal in the tumor area. In the clinical examination the patient had no neurological deficits and to-date the patient is still stable
CONCLUSION
Complete response was observed following combination treatment of chemoradiation with TMZ including proton boost, TMZ maintenance and TTFields in a patient with pathologically confirmed GBM IDH wildtype. To our knowledge, this is the first report on a ndGBM patient receiving proton therapy followed by TTFields therapy.

Abstract
The adrenal glands are small endocrine organs located on the bottom pole of each kidney. Anatomically they are composed of cortical and medullar parts. Due to dysfunctional processes they can transform into the pathological lesions (in both cortex and medulla). The incidentally detected adrenal lesions have become an arising clinical problem nowadays. The crucial issue for an accurate treatment strategy is relevant diagnosis. Distinguishing between benign and malignant lesions is often difficult during the standard histological examination. Hence the alternative methods of differentiation are investigated. One of them is Fourier transform infrared spectroscopy which allows the analysis of the biomolecular composition of the studied tissue. In this paper we present the very preliminary FTIR studies for defining the biomolecular pattern of three types of adrenal lesions: adenoma (AA) and adrenal cortical hyperplasia (ACH) - both derived from adrenal cortex as well as pheochromocytoma (PCC) - from the medullar part of the gland. All studied cases were classified as benign lesions. The general observations show that cortically derived tissues are rich in lipids and they are rather protein depleted while for medullar pheochromocytoma there is the opposite relationship. Furthermore, the unequivocal differences were noticed within the "fingerprinting" range. In addition subtle shifts in absorption band positions were observed between studied cases.

Abstract
Purine analogue roscovitine, a cyclin-dependent kinase (CDK) inhibitor, has shown strong anti-proliferative and pro-apoptotic effects in solid and hematologic cancers such as non small-cell lung cancer and lymphomas. It targets CDK2, 7 and 9 preferentially, which are also overexpressed in glioblastoma. Τherefore, the biological effects of roscovitine in glioblastoma cell lines were investigated. Glioblastoma A172 and G28 cell lines were incubated with serial concentrations of roscovitine for 24-120 h. Proliferation was measured using the xCELLigence Real-Time Cell Analyzer, an impedance‑based cell viability system. Cell cycle distribution was assessed by flow cytometry and gene expression was quantified by quantitative RT-PCR and western blot analysis. Roscovitine exhibited a clear dose-dependent anti‑proliferative and pro‑apoptotic effect in the A172 cell line, while G28 cells showed a anti-proliferative effect only at 100 µM. The results of the flow cytometric (FACS) analysis revealed a dose-dependent increase of the G2/M and sub-G1 fractions in A172 cells, while G28 cells responded with an elevated sub-G1 fraction only at the highest concentration. Roscovitine led to a dose‑dependent decrease of transcripts of p53, CDK 7 and cyclins A and E and an increase of >4-fold of p21 in A172 cells. In G28 cells, a dose‑dependent induction of CDK2, p21 and cyclin D was observed between 10 and 50 µM roscovitine after 72 h, however, at the highest concentration of 100 µM, all investigated genes were downregulated. Roscovitine exerted clear dose-dependent anti-proliferative and pro-apoptotic effects in A172 cells and less distinct effects on G28 cells. In A172 cells, roscovitine led to G2/M arrest and induced apoptosis, an effect accompanied by induced p21 and a reduced expression of CDK2, 7 and 9 and cyclins A and E. These effects requre further studies on a larger scale to confirm whether roscovitine can be used as a therapeutic agent against glioblastoma.

Abstract
In Germany, each site using ionising radiation in human medicine is assigned to a competent medical authority (CMA) for quality assurance. Duties of these CMAs are, e.g. the inspection of medical aspects of the use of X-rays and nuclear medicine at the sites as well as technical quality assurance of X-ray devices. The CMAs themselves have to report the collected exposure values to the ministries and the Federal Office for Radiation Protection. The IVEU (IT-gestütztes Verfahren zur Erfassung von Untersuchungsparametern) Software Framework assists CMAs and radiological departments in collecting and analysing data provided in DICOM headers.

Abstract
Bacillus anthracis is a spore-forming, Gram-positive microorganism. It is a causative agent of anthrax, a highly infectious disease. It belongs to the "Bacillus cereus group", which contains other closely related species, including Bacillus cereus, Bacillus thuringiensis, Bacillus mycoides, Bacillus weihenstephanensis, and Bacillus pseudomycoides. B. anthracis naturally occurs in soil environments. The BA5345 genetic marker was used for highly specific detection of B. anthracis with TaqMan probes. The detection limit of a real-time PCR assay was estimated at the level of 16.9 copies (CI95% - 37.4 to 37.86, SD = 0.2; SE = 0.118). Oligonucleotides designed for the targeted sequences (within the tested locus) revealed 100 % homology to B. anthracis strain reference sequences deposited in the database (NCBI) and high specificity to all tested B. anthracis strains. Additional in silico analysis of plasmid markers pag and cap genes with B. anthracis strains included in the database was carried out. Our study clearly indicates that the BA5345 marker can be used with success as a chromosomal marker in routine identification of B. anthracis; moreover, detection of plasmid markers indicates virulence of the examined strains.

Abstract
OBJECTIVE The present study aims to provide preliminary results of the thermal effects on rat brain tissue after argon plasma coagulation (APC). It also presents and discusses the clinical experiences in the treatment of brain tumor using APC. MATERIALS AND METHODS A controlled study of APC in the rat brain was conducted. Twelve rats were randomly divided into 2 experimental groups. In the first group (n = 6), histopathological evaluation was performed 2 days following the coagulation. In the second group (n = 6), the evaluation was performed 12 days post operation. In a prospective study of APC-treated tumor tissue in 3 patients, the depth of plasma penetration and histological alteration were evaluated. RESULTS In the animal experiment, extent of tissue defect became significantly smaller after 12 days (p = 0.010). The maximum depth of tissue alteration after APC application was limited to 2.15 mm (range: 1.5-2.15 mm) at day 2. The histological alteration of tissue after the thermal injury can be divided into 3 zones. In addition, the depth of tissue alteration in the APC-treated human brain tumor was measured in vertical and horizontal planes under light microscope. Similar to the animal experiment result, penetration of the plasma energy in human brain tumors was limited to a maximum of 2.13 mm (range: 1.6-2.13 mm). CONCLUSION The limited depth of energy penetration may confirm APC as a safe and beneficial tool for coagulation of human brain tissue. However, further clinical studies are required to evaluate the suitability and indications of this method in brain tumor treatment.

Abstract
The enzyme activity and the expression (protein and mRNA concentrations) of genes encoding for hepatic carnitine palmitoyl-transferases (CPT) I and II were studied during neonatal development, in response to nutritional state at weaning and during the fed-starved transition in adult rats. The activity, the protein concentration and the level of mRNA encoding CPT I are low in foetal-rat liver and increase 5-fold during the first day of extra-uterine life. The activity and gene expression of CPT I are high during the entire suckling period, in the liver of 30-day-old rats weaned at 20 days on to a high-fat diet and in the liver of 48 h-starved adult rats. The activity and CPT I gene expression are markedly decreased in the liver of rats weaned on to a high-carbohydrate diet. By contrast, the activity, the protein concentration and the level of mRNA encoding CPT II are already high in the liver of term foetuses and remain at this level throughout the suckling period, irrespective of the nutritional state of the animals either at weaning or in the adult.

Abstract
Thrombotic thrombocytopenic purpura is a clinical syndrome defined by the pentad of thrombocytopenia, microangiopathic hemolytic anemia, fever, and renal and neurologic abnormalities. The pathogenesis of this syndrome remains enigmatic, though appropriate management usually involves plasma administration. The authors report on an alternative therapy, high-dose intravenous immunoglobulin, used in the patient after the failure of plasmapheresis. The implications and potential applications of this therapy are discussed.

Abstract
This study examined the convergent and divergent validity of heart-rate (HR)-based response discrepancy scores as measures of denial. After standardizing measures of stressor-related anxiety, hostility, and HR, response discrepancy scores were calculated by subtracting each measure of negative affect from the HR value. Analyses revealed the response discrepancy scores to correlate positively with measures of denial, negatively with a measure of trait anger, and to not correlate with measures of the nondefensive need for approval and the positive trait of curiosity. These findings support the construct validity of response discrepancy scores as markers of denial.

Abstract
The subunits that comprise the platelet-specific integrin alpha IIb beta 3 are polymorphic in nature, with several allelic forms present in the human gene pool. Minor changes in the secondary and tertiary structures of platelet membrane glycoproteins (GP) IIb and IIIa encoded by these alleles can result in an alloimmune reaction after transfusion or during pregnancy. To better understand the molecular structure of the PlA alloantigen system, located on GPIIIa, and the Bak alloantigen on GPIIb, we used a heterologous mammalian expression system to express these integrin subunits in their known polymorphic forms. An expression vector containing the PlA1 form of a GPIIIa cDNA, which encodes a leucine at amino acid 33 (Leu33), was modified to express the PlA2-associated form encoding a proline at amino acid 33 (Pro33). Similarly, a Baka GPIIb cDNA expressing an isoleucine at amino acid 843 (IIe843) was modified to express the Bakb form containing a serine at the same position (Ser843). Transfection of these vectors into COS cells resulted in the synthesis of GPIIb and GPIIIa molecules that were identical in size to those present in platelet lysates. Immunoprecipitation of the GPIIIa-transfected COS lysates with PlA)-specific alloantisera indicated that the Leu33 form was recognized only by anti-PIA1 sera while the Pro33 form was bound only by anti-PlA2 sera, showing that single amino acid polymorphisms are necessary and sufficient to direct the formation of the PlA1 and PlA2 alloepitopes. Similar experiments with Bak allele-specific expression vectors indicated that while the amino acid polymorphism (IIe843 in equilibrium Ser843) was necessary, posttranslational processing of pro-IIb was required for efficient exposure of both the Baka and Bakb alloepitopes.
