Long-term effect and safety of mesenchymal stromal cell therapy for radiation-induced hyposalivation in head and neck cancer survivors: A randomised, phase-2, trial.

Background: The long-term effect of adipose-derived mesenchymal stromal cells (ASCs) to restore radiation-induced salivary gland hypofunction in previous head and neck cancer patients have not been validated in larger settings.

Methods: The study was the 12-months follow-up of a randomised trial, including patients with hyposalivation. Patients were randomised to receive allogeneic ASCs or placebo in the submandibular glands.

Long-Term Outcome Following Treatment With Allogeneic Mesenchymal Stem/Stromal Cells for Radiation-Induced Hyposalivation and Xerostomia.

Background: Adipose-derived mesenchymal stem/stromal cells (ASCs) are proposed as a new xerostomia treatment. The study evaluated the long-term safety and effectiveness of allogeneic ASCs in radiation-induced xerostomia among patients with previous oropharyngeal cancer.

Methods: This study constitutes 3-year follow-up on the original 10 patients who received allogeneic ASCs injections to the submandibular and parotid glands as part of the MESRIX-II trial.

Identification of the novel HLA allele HLA-DRB1*03:201 by next-generation sequencing.

HLA-DRB1*03:201 differs from HLA-DRB1*03:01 in exon 3 at codon 178 resulting in a proline to serine substitution.

Detection of the novel HLA allele, HLA-DQA1*01:65, identified in a Danish donor.

HLA-DQA1*01:65 differs from HLA-DQA1*01:03 in exon 1 at amino acid -7 a valine to methionine substitution.

The HLA-DR4-DQ8 phenotype of the recipient is associated with increased mortality after kidney transplantation.

The importance of the human leukocyte antigen (HLA) system in kidney transplantation is well-known, but it remains unexplored if patient HLA antigens constitute independent risk factors in complications after transplantation. We hypothesized that specific HLA class II phenotypes associated with immune-mediated disease (HLA-IMD) predispose to immunological activity and/or complications after kidney transplantation. Based on the literature we defined HLA-DR2-DQ6; -DR3-DQ2 and -DR4-DQ8 as HLA-IMD phenotypes.

Identification of the novel HLA allele, HLA-DPA1*01:46, identified in a man of Serbian origin.

HLA-DPA1*01:46 differs from HLA-DPA1*01:03 in exon 2 at amino acid 85; Aspartate to Asparagine substitution.

[Donor search for haematopoietic stem cell transplantation].

Allogeneic haematopoietic stem cell transplantation is a clinical example of precision medicine, as one individual donor is selected for one individual patient based on genetic findings in the human leukocyte antigen (HLA) system. Unrelated donor search for Danish patients is based on an international collaboration between global registries hosting more than 37 million potential donors worldwide for patients in need. The implementation of next-generation sequencing technologies has been a revolution in donor registry typing due to more precise, detailed and cheaper HLA analyses, which is discussed in this review.

The nitric oxide synthase inhibitor and serotonin-receptor agonist NXN-188 during the aura phase of migraine with aura: A randomized, double-blind, placebo-controlled cross-over study.

Background and aims NXN-188 is a combined neuronal nitric oxide synthase (nNOS) inhibitor and 5HT-1B/1D receptor agonist which has previously shown efficacy in the acute treatment of migraine. Nitric oxide (NO) is involved in the pathogenesis of migraine pain and is formed after cortical spreading depression. Therefore NXN-188 could perhaps prevent the development of the headache phase in migraine with aura if taken during the aura.

Addition of plerixafor for CD34+ cell mobilization in six healthy stem cell donors ensured satisfactory grafts for transplantation.

Background: In allogeneic hematopoietic stem cell (HSC) transplantation, collection of a sufficient number of HSCs at a fixed time point is crucial. For HSC mobilization into the peripheral blood, the standard regimen, that is, granulocyte-colony-stimulating factor (G-CSF), may be inadequate. Use of plerixafor as adjuvant to G-CSF is so far off-label in healthy donors.

Glutamate dehydrogenase isoforms with N-terminal (His)6- or FLAG-tag retain their kinetic properties and cellular localization.

Glutamate dehydrogenase (GDH) is a crucial enzyme on the crossroads of amino acid and energy metabolism and it is operating in all domains of life. According to current knowledge GDH is present only in one functional isoform in most animals, including mice. In addition to this housekeeping enzyme (hGDH1 in humans), humans and apes have acquired a second isoform (hGDH2) with a distinct tissue expression profile.

Provocation of migraine with aura using natural trigger factors.

Objective: It is well-known that migraine attacks can be precipitated by various stimuli. More than 50% of patients with migraine with aura (MA) know of at least one stimulus that always or often triggers their MA attacks. The objective of this study was to expose patients with MA to their self-reported trigger factors in order to assess the causal relation between trigger factors and attacks.

Trigger factors for familial hemiplegic migraine.

Objective: The aim was to identify and describe migraine trigger factors in patients with familial hemiplegic migraine (FHM) from a population-based sample.

Methods: 127 FHM patients were sent a questionnaire listing 16 trigger factors. Distinction was made between attacks of hemiplegic migraine (HM) and migraine with aura (MA) or without aura (MO) within each patient.

Calcitonin gene-related peptide triggers migraine-like attacks in patients with migraine with aura.

Introduction: Calcitonin gene-related peptide (CGRP) is a key molecule in migraine pathogenesis. Intravenous CGRP infusion triggers delayed migraine-like attacks in patients with migraine without aura (MO). In contrast to patients with MO, in prior studies patients with familial hemiplegic migraine (FHM) did not report more migraine-like attacks compared to controls.

Characterization of consistent triggers of migraine with aura.

Objective: The aim of the present study was to characterize perceived consistent triggers of migraine with aura (MA).

Method: Questionnaires specifically designed to characterize various trigger factors were sent to 181 participants identified in an earlier study. All participants had formerly identified at least one factor that often or always triggered an MA attack.

Genome-wide association study of migraine implicates a common susceptibility variant on 8q22.1.

Migraine is a common episodic neurological disorder, typically presenting with recurrent attacks of severe headache and autonomic dysfunction. Apart from rare monogenic subtypes, no genetic or molecular markers for migraine have been convincingly established. We identified the minor allele of rs1835740 on chromosome 8q22.

On the methodology of drug trials in migraine with aura.

Introduction: Specific problems occur in clinical treatment trials for migraine with aura that differ from those encountered in treatment trials for migraine without aura.

Discussion: Based on our experience with four such trials, we point to a number of possible solutions and outline areas for future inquiry. We make recommendations about subject selection; the choice, definition and assessment of outcome measures; optimal treatments in relation to aura and headache; and we provide samples of study report forms used to record occurrence of aura and headache in this population.

Effects of tonabersat on migraine with aura: a randomised, double-blind, placebo-controlled crossover study.

Background: Migraine with aura is thought likely to be caused by cortical spreading depression (CSD). Tonabersat inhibits CSD, and we therefore investigated whether tonabersat has a preventive effect in migraine with aura.

Methods: In this randomised, double-blind, placebo-controlled crossover trial, 40 mg tonabersat once daily was compared with matched placebo in patients who had at least one aura attack per month during the past 3 months.
