In a Swedish sample of persons eligible for disability services and aged 55 years or older in 2012, persons (n = 601) with autism spectrum disorder diagnoses registered in specialist care were identified. Register data concerning diagnoses of other psychiatric disorders, psychiatric care, and psychiatric medication were reviewed. More than 60% had been in contact with psychiatric care. The majorit
Autoimmune (type 1) diabetes (AI-DM) is a multistage disorder. Children are born genetically predisposed to putative environmental exposures. These trigger an aggressive, selective and chronic autoimmune response against the pancreatic islet beta cells. This stage is marked by autoantibodies against insulin, glutamic acid decarboxylase (GAD65), IA-2 and the ZnT8 transporter. Progression to clinica
Data on longitudinal lung function change in the elderly are scarce. Uncertainty remains about whether to use absolute or relative change and how it relates to subject demographics.We studied absolute and relative forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) change in a population-based geriatric sample using a repeated measurements model adjusted for age, sex, smoking ha
Malignant melanoma (MM) is a frequent form of cancer with increasing incidence. 6-10% of patients with MM report a family history of MM, and in most populations 2% of unselected cases of MM carry a CDKN2A mutation. tvWe present a family with 24 cases of MM in nine persons from several generations, caused by a previously undescribed germ-line intronic mutation in CDKN2A. Through genetic counselling
We studied the A-band photodissociation of bromoiodomethane, CH2BrI, in acetonitrile solution at room temperature by femtosecond pump-probe spectroscopy, Initiated by the 266 nm light, this reaction leads to the CH2Br-I isomer, most likely produced via in-cage recombination of the CH,Br and I photofragments. The isomer is formed vibrationally excited with a time constant of similar to7.5 ps and th
Popular Abstract in Swedish Prostaglandiner och tromboxaner är hormonliknande ämnen som består av cykliska fleromättade fettsyror. Karakteristiskt för alla prostaglandiner är att de har en mycket kort halveringstid, de verkar lokalt, kan ej lagras i vävnader och att produktionen hämmas av aspirin (acetylsalicylsyra). Prostacyklin och tromboxan är två prostaglandiner med i stort sett motsatta effekThe fetoplacental circulation is a low pressure system with a high vascular prostacyclin to thromboxane (Pc/Tx)synthesis ratio. In intrauterin growth restriction (IUGR) and diabetes the prostanoid balance may be altered. AIMS: To investigate relationships between umbilicoplacental vascular prostanoid synthesis (by incubation of vessel samples), circulatory changes (by Doppler velocimetry of umbili
About 8000 Swedish women are diagnosed with breast cancer each year, and around 1500 die from the disease. Triple-negative breast cancer (TNBC) constitutes 7-14% of all breast cancer and is characterized by an aggressive phenotype with poor prognosis and no targeted therapy available. The aim of this thesis was to evaluate new potential prognostic biomarkers in breast cancer, and with special focu
Background: Bladder cancer is categorized as non-muscle invasive (NMIBC) or muscle invasive (MIBC). NIMBC makes up around 70% of the cases and although it is less aggressive, the recurrence rate is 50-70%, thus requiring extensive monitoring. Additionally, there is a risk of progression into MIBC with a 5-year survival of only 50% even when treated with radical cystectomy. Immune checkpoint inhibi
Human exposures to metals and metalloids such as arsenic frequently occur as mixtures, and hence it is important to consider interactions among these elements in terms of both mechanisms of action and for risk assessment purposes. Interactions among these elements may produce additive, synergistic/potentiative, or antagonistic effects that may be manifested as direct cellular toxicity (necrosis or
Sustainably produced renewable biomass has the potential to replace fossil-based feedstocks, for generation of biobased fuels and chemicals of industrial interest, in biorefineries. In this context, seaweeds contain a large fraction of carbohydrates that are a promising source for enzymatic and/or microbial biorefinery conversions. The thermoanaerobe Thermoanaerobacterium AK17 is a versatile ferme
Spatial transcriptomics (ST) maps RNA level patterns within a tissue. This technology has not been previously applied to human placental tissue. We demonstrate analysis of human placental samples with ST. Unsupervised clustering revealed that distinct RNA patterns were found corresponding to different morphological structures. Additionally, when focusing upon terminal villi and hemoglobin associat
Suicide among children and young adults is a leading cause of mortality, highlighting the importance of the development of life-saving interventions. This study is part of the nationwide study Retrospective investigation of health care utilization of individuals who died by suicide in Sweden in 2015, Lund University, Sweden. The aim was to gain a better understanding of verbal suicidal communicati
The SNP rs13266634 encodes either an Arginine (R) or a Tryptophan (W) (R325W) at the amino acid position 325 in the Zinc Transporter 8 (ZnT8) protein. Autoantibodies (Ab) that recognize ZnT8R, ZnT8W or both at the polymorphic site are common in newly diagnosed type 1 diabetes (T1D) patients. The epitope specificity and affinity of ZnT8Ab are poorly understood, but may be of importance for the pred
Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a group of autoimmune diseases, including granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). It is not known why ANCA develop, but it has been shown that they participate in pathogenesis by activating polymorphonuclear neutrophils (PMNs). In this study we hypothesize that dysregulation of phagocytosi
We present a novel method for the determination of density and compressibility of individual particles and cells undergoing microchannel acoustophoresis in an arbitrary 2D acoustic field. Our method is a critical advancement within acoustophoretic separation of biological cells, as the ability to determine the density and compressibility of individual cells enables the prediction and alteration of
