Effects of foam rolling on vastus intermedius and lateralis microvascular blood flow.

Introduction: Foam Rolling (FR) as a technique of self-massage has become a widely used intervention in clinical and sports practice. It is assumed that FR leads to an increased intramuscular microvascular blood flow (MBF), and therefore is commonly recommended as a warm-up or regeneration method. However, no data validate the effects of FR on MBF.

Medical centres for the homeless in Hamburg - consultation reasons and diagnoses compared to primary care patients in the regular health care system.

Background: In Germany, homeless people are entitled to health care within the regular health care system. However, due to their specific living conditions they make little use of these services. In 2013, three Medical centres for the homeless (MCH) were opened in Hamburg to provide general health care.

Partnership, sexuality, and fertility-related communication: findings from a register-based study among long-term hematological cancer survivors.

Purpose: Even though the number of hematological cancer survivors suffering from long-term and late consequences of their disease is growing, knowledge about their situation regarding partnership, sexuality, and fertility-related communication is sparse to date.

Methods: We recruited survivors of hematological malignancies (≥ 3 years after diagnosis) from two cancer registries in Germany. We applied validated instruments and study-specific items on satisfaction with partnership, sexual functioning, and fertility-related communication with physicians.

The RhoGAP-myosin Myo9b regulates ocular lens pit morphogenesis.

Background: During eye development the lens placode invaginates to form the lens pit. Further bending of lens epithelium and separation from ectoderm leads eventually to a spherical lens vesicle with enclosed extracellular fluid. Changes in epithelial morphology involve the actin cytoskeleton and its regulators.

Acceptance of medications for opioid use disorder in recovery housing programs in Missouri.

Background: Recovery housing plays an important role in supporting individuals in their recovery by building recovery capital and providing stable living environments; however, the extent to which medications for opioid use disorder (MOUD), the gold standard for OUD treatment, are accepted in recovery housing settings is unclear. The purpose of this study, as part of a larger statewide evaluation of Missouri recovery homes, was to identify the extent to which Missouri recovery houses were accepting of methadone, buprenorphine, and naltrexone as well as the extent to which the acceptance of each medication was linked to whether the recovery home encouraged tapering off MOUDs.

Methods: Sixty-four recovery housing managers and/or staff, out of 66 eligible recovery homes in Missouri completed the survey.

A System Identification and Implementation of a Soft Sensor for Freeform Bending.

The primary goal of this study is the formulation of a soft sensor that predicts industrially relevant mechanical properties for freeform bending. This serves as the foundation of a closed-loop property control. It is hypothesized that by inline measurement of hardness, predictions regarding residual hoop stresses, local strength and strain level can be achieved.

Local Myo9b RhoGAP activity regulates cell motility.

To migrate, cells assume a polarized morphology, extending forward with a leading edge with their trailing edge retracting back toward the cell body. Both cell extension and retraction critically depend on the organization and dynamics of the actin cytoskeleton, and the small, monomeric GTPases Rac and Rho are important regulators of actin. Activation of Rac induces actin polymerization and cell extension, whereas activation of Rho enhances acto-myosin II contractility and cell retraction.

Interferon-β exposure induces a fragile glioblastoma stem cell phenotype with a transcriptional profile of reduced migratory and MAPK pathway activity.

Background: Type I interferons (IFN-α/β) are cytokines that are typically expressed in response to double-stranded RNA associated with viral infections. Glioblastomas are the most common malignant primary brain tumors, characterized by an infiltrative growth pattern and prominent angiogenic activity, and thought to be maintained by a subpopulation of glioma-initiating (stem-like) cells (GICs). The growth of human GIC lines is highly sensitive to IFN-β.

Interferon-β sensitizes human glioblastoma cells to the cyclin-dependent kinase inhibitor, TG02.

Novel treatments for glioblastoma, the most common malignant primary brain tumor, are urgently required. Type I interferons (IFN) are natural cytokines primarily involved in the defense against viral infections, which may also serve a role in the control of cancer, notably in the suppression of the cancer stem cell phenotype. TG02 is a novel orally available cyclin-dependent kinase 9 inhibitor which induces glioma cell apoptosis without profound caspase activation, which is currently explored in early clinical trials in newly diagnosed and recurrent glioblastoma.

Profound, durable and MGMT-independent sensitivity of glioblastoma cells to cyclin-dependent kinase inhibition.

TG02 is a novel cyclin-dependent kinase (CDK) inhibitor and thought to act mainly via CDK-9 inhibition-dependent depletion of short-lived oncoproteins such as MCL-1 or c-MYC. We studied the activity of TG02 in 9 human long-term glioma cell lines (LTC) and 5 glioma-initiating cell lines (GIC) using various cell death assays in vitro and in the LN-229 LTC and ZH-161 GIC models in vivo. TG02 exhibits strong anti-tumor cell activity with EC concentrations in the nanomolar range.

Age-associated and therapy-induced alterations in the cellular microenvironment of experimental gliomas.

The poor prognosis associated with advanced age in patients with glioblastoma remains poorly understood. Glioblastoma in the elderly has been particularly associated with vascular endothelial growth factor (VEGF)-dependent angiogenesis, and early uncontrolled studies suggested that the anti-angiogenic agent bevacizumab (BEV), an antibody to VEGF, might be preferentially active in this patient population. Accordingly, we explored host age-dependent differences in survival and benefit from radiotherapy (RT) or BEV in syngeneic mouse glioma models.

Entanglement and Bell Correlation in Electron-Exchange Collisions.

Elastic collisions between initially unpolarized electrons and hydrogenlike atoms are discussed, aiming to analyze the entanglement properties of the correlated final spin system. Explicit spin-dependent interactions are neglected and electron exchange only is taken into account. We show the final spin system to be completely characterized by a single spin correlation parameter depending on scattering angle and energy.

Risk Assessment of residual monomer migrating from acrylic polymers and causing Allergic Contact Dermatitis during normal handling and use.

Acrylic, Poly Methyl Methacrylate (PMMA) based polymers are found in many industrial, professional and consumer products and are of low toxicity, but do contain very low levels of residual monomers and process chemicals that can leach out during handling and use. Methyl Methacrylate, the principle monomer is of low toxicity, but is a recognized weak skin sensitizer. The risk of induction of contact allergy in consumers was determined using a method based upon the Exposure-based Quantitative Risk Assessment approach developed for fragrance ingredients.

Interleukin-17 impedes Schwann cell-mediated myelination.

Background: Pro-inflammatory cytokines are known to have deleterious effects on Schwann cells (SCs). Interleukin 17 (IL-17) is a potent pro-inflammatory cytokine that exhibits relevant effects during inflammation in the peripheral nervous system (PNS), and IL-17-secreting cells have been reported within the endoneurium in proximity to the SCs.

Methods: Here, we analyzed the effects of IL-17 on myelination and the immunological properties of SCs.

A dynamical (e,2e) investigation of the structurally related cyclic ethers tetrahydrofuran, tetrahydropyran, and 1,4-dioxane.

Triple differential cross section measurements for the electron-impact ionization of the highest occupied molecular orbitals of tetrahydropyran and 1,4-dioxane are presented. For each molecule, experimental measurements were performed using the (e,2e) technique in asymmetric coplanar kinematics with an incident electron energy of 250 eV and an ejected electron energy of 20 eV. With the scattered electrons being detected at -5°, the angular distributions of the ejected electrons in the binary and recoil regions were observed.

Dynamical (e,2e) studies of tetrahydrofurfuryl alcohol.

Cross section data for electron scattering from DNA are important for modelling radiation damage in biological systems. Triply differential cross sections for the electron impact ionization of the highest occupied outer valence orbital of tetrahydrofurfuryl alcohol, which can be considered as an analogue to the deoxyribose backbone molecule in DNA, have been measured using the (e,2e) technique.

Stabilizing frequency weighted controller reduction approach.

This note addresses the problem of instability in frequency weighted controller reduction methods based on similarity transformations. The aim is to reduce the complexity of the controllers derived by modern controller design packages for practical applications. For a given controller a framework is proposed that parameterizes a set of reduced controllers that preserve the stability of the closed loop system.

Young-type interference in (e, 2e) ionization of H(2).

We have investigated the electron impact single ionization of the hydrogen molecule, with fully determined kinematics. The experimental and theoretical results are compared with He ionization under the same conditions. The results indicate that the ejected electron angular distribution for H(2) is modified due to Young-type interference between ionization amplitudes for scattering from the two centers in the hydrogen molecule.

Clinical value of parathyroid scintigraphy with technetium-99m methoxyisobutylisonitrile: discrepancies in clinical data and a systematic metaanalysis of the literature.

There is a considerable discrepancy in the literature concerning the sensitivity of parathyroid scintigraphy (PS) with 99mTc-MIBI. We therefore analyzed our own data and compared them to the literature in a metaanalysis. All patients who received 99mTc -MIBI scintigraphy and subsequent surgery in our department for the detection of enlarged parathyroid glands in primary (pHPT) or secondary (sHPT) hyperparathyroidism between 1991 and 1999 were included in our retrospective analysis.

Gi- and protein kinase C-mediated heterologous potentiation of phospholipase C signaling by G protein-coupled receptors.

We recently reported that activation of the highly efficient phospholipase C (PLC) stimulatory m3 muscarinic acetylcholine receptor (mAChR) can induce a long-lasting Gi-mediated heterologous potentiation of PLC stimulation in human embryonic kidney (HEK) 293 cells, which was accompanied by an increased cellular level of the PLC substrate phosphatidylinositol-4,5-bisphosphate [PtdIns(4,5)P2]. Here, we examined whether such a potentiated PLC response is also induced by the rather poorly PLC stimulatory m2 mAChR and the endogenously expressed purinergic and lysophosphatidic acid receptors. Pretreatment of m2 mAChR-expressing HEK 293 cells for 2 min with carbachol, followed by agonist washout and measurement of PLC activity >/=40 min later, caused a long-lasting (up to approximately 90 min) heterologous potentiation of receptor- and G protein-mediated PLC stimulation.

Regulation of phospholipase C and D activities by small molecular weight G proteins and muscarinic receptors.

The role of small molecular weight guanine nucleotide-binding proteins (G proteins) of the Rho family in muscarinic acetylcholine receptor (mAChR) signaling to phospholipase C (PLC) and phospholipase D (PLD) was studied in human embryonic kidney (HEK) cells, stably expressing the human m3 receptor subtype. Evidence for the involvement of Rho proteins in m3 mAChR signaling to both phospholipases is based on findings obtained with Clostridium (C.) difficile toxin B and C.
