- Objective: This paper aims at studying the influence of single-nucleotide polymorphisms (SNPs) on cancer risk, tumor recurrence, and survival in head and neck (H&N) cancer patients. Methods: A total of 45 SNPs in 41 genes were investigated. A total of 174 Caucasian H&N cancer patients and 245 healthy blood donors were enrolled in the study. Results: Ten SNPs were associated with H&N cancer risk, but the identified SNPs differed among males and females. Some of the SNPs were related to immune response genes. The immune response gene SNPs were also related to survival. In particular, we noted that the tumor necrosis factor alpha (TNFα) rs1800629 could have an influence on cancer risk, tumor recurrence as well as survival. Conclusion: Genetic variation of the TNFα rs1800629 might be useful as a biomarker in clinical decision-making since it was found to be related to cancer risk, tumor recurrence, and survival of H&N cancer patients.

Forskningsöversikt (refereegranskat)abstract
- The exploration of the unique properties of stored and cooled beams of highly-charged ions as provided by heavy-ion storage rings has opened novel and fascinating research opportunities in the realm of atomic and nuclear physics research. Since the late 1980s, pioneering work has been performed at the CRYRING at Stockholm (Abrahamsson et al. 1993) and at the Test Storage Ring (TSR) at Heidelberg (Baumann et al. 1988). For the heaviest ions in the highest charge-states, a real quantum jump was achieved in the early 1990s by the commissioning of the Experimental Storage Ring (ESR) at GSI Helmholtzzentrum für Schwerionenforschung (GSI) in Darmstadt (Franzke 1987) where challenging experiments on the electron dynamics in the strong field regime as well as nuclear physics studies on exotic nuclei and at the borderline to atomic physics were performed. Meanwhile also at Lanzhou a heavy-ion storage ring has been taken in operation, exploiting the unique research opportunities in particular for medium-heavy ions and exotic nuclei (Xia et al. 2002).

- Bell's palsy is an acute unilateral weakness or paralysis of the face of unknown cause. The incidence of the disease is 30 individuals per 100,000 per year. It is a diagnosis of exclusion and other known causes for acute peripheral facial palsy must be ruled out. The prognosis is overall favorable and about 70% of the patients recover completely within 6 months without treatment. Recent randomized controlled Bell's palsy trials have shown that treatment with corticosteroids shortens time to recovery and improves recovery rates while antiviral treatment alone is not more effective than placebo. The combination of corticosteroids and antivirals has not been proven more effective than corticosteroids alone. We present an update of Bell's palsy in adults with focus on diagnosis, treatment and follow-up of these patients.

- In 2012 the CRYRING storage ring was delivered from Stockholm to Darmstadt as a part of the Swedish in-kind contribution to the FAIR project. The ring lattice has been slightly changed for optimal injection and to provide additional space for experiment equipment. For the injection from the experimental storage ring (ESR), a new transfer line has been designed. The local injector line has been significantly modified compared to the previous one in Stockholm taking into account the geometry of the existing GSI building. In this paper we present the ion-optical properties of CRYRING@ESR after the described modifications. Single-turn injection from the ESR and multi-turn injection from the local injector are discussed. Ion-optical calculations of fast and slow extraction from CRYRING are also presented. The closed orbit correction scheme is considered taking into account the future arrangement of the beam position monitors and correction magnets. Based on the results of the calculations the requirements for the magnet alignment are finally discussed.

- The former storage ring CRYRING has been shipped from the Manne Siegbahn Laboratory in Stockholm to Darmstadt as a Swedish in-kind contribution to FAIR. At its new location downstream of ESR all ion species presently accessible in ESR can be transferred to CRYRING, in which ions with rigidities between 1.44 and 0.054 Tm can be stored. The original Swedish layout has been modified by reconfiguring the sequence of straight sections and by slightly increasing the circumference to ESR/2. Ions can be injected from ESR or from an independent 300 keV/u RFQ test injector. The instrumentation of the ring includes an RF drift tube system for acceleration and deceleration (1 T s(-1), with a possibility for an upgrade to 7 T s(-1)), electron cooling, a free experimental section, and both fast and slow extraction of ions. We report on the present progress of this project, give a prospective timeline, and summarize the new research which will be enabled by this project. First beam for commissioning of the storage ring is expected for 2015, final bakeout to restore ultrahigh vacuum conditions in 2016 and ion beams injected through ESR in similar to 2017.

- Introduction: Tobacco and ethanol consumption are crucial factors in the development of various diseases including cancer. In this investigation, we evaluated the combined effects of a number of single nucleotide polymorphisms (SNPs), with ethanol and tobacco products on healthy individuals. Methods: Pure nicotine, cigarette smoke extract, and Swedish snuff (snus) extract were used. The effects were examined by means of in vitro cell cycle progression and cell death of peripheral blood mononuclear cells (PBMCs) obtained from healthy donors. Results: After 3 days, in vitro, resting PBMCs entered the S and G2 stage in the presence of 100 mu M nicotine. The PBMCs only proceeded to S stage, in the presence of 0.2% ethanol. The nicotine- and ethanol-induced normal cell cycle progression correlated to a number of SNPs in the IL12RB2, Rad 52, XRCC2, P53, CCND3, and ABCA1 genes. Certain SNPs in Caspases 8, IL12RB2, Rad 52, MMP2, and MDM2 genes appeared to significantly influence the effects of EtOH-, snus-, and snus + EtOH-induced cell death. Importantly, the highest degree of cell death was observed in the presence of smoke + EtOH. The amount of cell death under this treatment condition also correlated to specific SNPs, located in the MDM2, ABCA1, or GASC1 genes. Conclusions: Cigarette smoke in combination with ethanol strongly induced massive cell death. Long-term exposure to smoke and ethanol could provoke chronic inflammation, and this could be the initiation of disease including the development of cancer at various sites.

Tidskriftsartikel (refereegranskat)abstract
- Conclusion: Swedish versions of the Facial Disability Index (FDI) and Facial Clinimetric Evaluation (FaCE) scale are psychometrically valid. Both questionnaires can be used for clinical studies on peripheral facial palsy patients, and provide important information on quality of life. Objectives: To translate and validate Swedish versions of the FDI and FaCE scale in patients with peripheral facial palsy. Methods: Translation of the original questionnaires followed international guidelines. Internal consistency and test-retest stability were assessed in adult patients with stable peripheral facial palsy. Facial function was examined with the Sunnybrook and House-Brackmann scales. Subjects answered the questionnaires twice with a 2-week interval. Validity was assessed by comparing FDI and FaCE scale scores to SF-36 and Sunnybrook/House-Brackmann scores. Results: Ninety-three patients were included, 53% women and 47% men, mean age 56.9 years and mean duration of palsy 51.9 months. The questionnaires showed good/excellent psychometric properties with Cronbach's alpha scores between 0.76 and 0.92. In the test-retest analysis, intra-class correlation coefficients were very good for both questionnaires with scores of 0.83-0.97. Both questionnaires showed good sensitivity to discriminate between patients with varying degrees of facial dysfunction. Moderate to strong correlation was found between the social domains in the questionnaires when compared with the equivalent domains in SF-36.
