Tryptophan catabolites as metabolic markers of vitamin B-6 status evaluated in cohorts of healthy adults and cardiovascular patients
(Journal article; Peer reviewed, 2020)Background Vitamin B-6 status is routinely measured as pyridoxal 5′-phosphate (PLP) in plasma. Low concentrations of PLP are associated with rheumatic, cardiovascular, and neoplastic diseases. We have previously shown ... -
Tsunami risk communication and management: Contemporary gaps and challenges
(Journal article; Peer reviewed, 2022)Very large tsunamis are associated with low probabilities of occurrence. In many parts of the world, these events have usually occurred in a distant time in the past. As a result, there is low risk perception and a lack ... -

(Peer reviewed; Journal article, 2015-07-17)Numbering in excess of 10 million per milliliter of water, it is now undisputed that aquatic viruses are one of the major factors shaping the ecology and evolution of Earth’s microbial world. Nonetheless, environmental ... -
The tuberculin skin test in school going adolescents in South India: associations of socio-demographic and clinical characteristics with TST positivity and non-response
(Peer reviewed; Journal article, 2014-11-18)Background. India has generally used 1 TU purified protein derivative (PPD) as opposed to 2 TU PPD globally, limiting comparisons. It is important to assess latent TB infection in adolescents given that they may be a target ... -

Tuberculosis control in Sidama in Ethiopia. Programme performance and spatial epidemiology
(Doctoral thesis, 2016-09-05)The Sustainable Development Goals are to end the TB epidemic by reducing the incidence of TB by 90 % and by reducing mortality by 95% by 2035 from what was in 2015. Globally, access to TB diagnostic and treatment facilities ... -
Tuberculosis recurrence in smear-positive patients cured under DOTS in southern Ethiopia: retrospective cohort study
(Peer reviewed; Journal article, 2009-09-18)Background: Decentralization of DOTS has increased the number of cured smear-positive tuberculosis (TB) patients. However, the rate of recurrence has increased mainly due to HIV infection. Recurrence rate could be taken ... -
Tuberculosis-Associated Hemophagocytic Lymphohistiocytosis: A Review of Current Literature
(Journal article; Peer reviewed, 2023)Hemophagocytic lymphohistiocytosis (HLH) is a condition of immune dysregulation and hyperinflammation, leading to organ failure and death. Malignancy, autoimmune conditions, and infections, including Mycobacterium tuberculosis ... -
"Tulla på stigen" - om Dorothea Platou Fischer og ein nekrolog som aldri vart skriven
(Årbok for Universitetsmuseet i Bergen;26, Chapter, 2021-12)Avisa New York Times bestemte seg i 2018 for å byrja å skriva nekrologane som aldri vart skrivne. Etter avisas meining hadde status, hudfarge eller kjønn for mange stengt døra til historiebøkene og den anerkjenninga som ... -
Tumor budding score predicts lymph node status in oral tongue squamous cell carcinoma and should be included in the pathology report
(Journal article; Peer reviewed, 2020)Background The majority of oral cavity cancers arise in the oral tongue. The aim of this study was to evaluate the prognostic value of tumor budding in oral tongue squamous cell carcinoma, both as a separate variable and ... -
Tumor HPV status, level of regulatory T cells and macrophage infiltration predict up to 20-year non-disease-specific survival in oropharynx squamous cell carcinoma patients
(Journal article; Peer reviewed, 2022)Oropharynx squamous cell carcinoma (OPSCC) is of special interest because human papilloma virus (HPV) and/or smoking cause this disease. Influxes of inflammatory cells into such tumors are known to vary with prognoses. ... -
Tumor infiltration levels of CD3, Foxp3 (+) lymphocytes and CD68 macrophages at diagnosis predict 5-year disease-specific survival in patients with oropharynx squamous cell carcinoma
(Journal article; Peer reviewed, 2022)Head and neck cancer (HNC) is the sixth most common cancer worldwide. Oropharyngeal (OP) cancers are of special interest because of possible underlying HPV infection which is tied to prognosis. Influxes of inflammatory ... -
Tumor interstitial fluid formation, characterization, and clinical implications
(Peer reviewed; Journal article, 2015-05-26)The interstitium, situated between the blood and lymph vessels and the cells, consists of a solid or matrix phase and a fluid phase representing the tissue microenvironment. In the present review, we focus on the interstitial ... -
Tumor necrosis is associated with increased alphav beta3 integrin expression and poor prognosis in nodular cutaneous melanomas
(Peer reviewed; Journal article, 2008-12-05)Background: Tumor necrosis and apoptotic activity are considered important in cancer progression, but these features have not been much studied in melanomas. Our hypothesis was that rapid growth in cutaneous melanomas of ... -
