Prostate-specific antigen (PSA) is a serine protease belonging to the human glandular kallikrein gene family [1–3]. The expression of PSA is mainly androgen dependent, and the detection of very high expression levels is restricted to the prostate tissue, but extraprostatic production at much lower levels has been demonstrated in several other tissues such as normal and malignant breast epithelium,
Hemoglobin (Hb)-based oxygen carriers (HBOC) are modified extracellular proteins, designed to replace or augment the oxygen-carrying capacity of erythrocytes. However, clinical results have generally been disappointing due to adverse side effects, in part linked to the intrinsic oxidative toxicity of Hb. Previously a redox-active tyrosine residue was engineered into the Hb β subunit (βF41Y) to fac
The hydrolysis of sphingomyelin (SM) generates important signals regulating cell proliferation and apoptosis. Acid and neutral sphingomyelinases (SMase) have been identified and their biological effects intensively studied. We recently found in human bile a novel alkaline SMase that may have important roles in hepatobiliary diseases. In this work, we purified the enzyme and studied the factors inf
In this study, a novel macroporous composite biomaterial consisting of gelatin-hydroxyapatite-calcium sulphate for delivery of bone morphogenic protein-2 (rhBMP-2) and zoledronic acid (ZA) has been developed. The biomaterial scaffold has a porous structure and functionalization of the scaffold with rhBMP-2 induces osteogenic differentiation of MC3T3-e1 cells seen by a significant increase in bioch
Melphalan at a dose of 200 mg/m2 is standard conditioning prior to autologous hematopoietic stem cell transplantation for multiple mulholger, but a dose of 140 mg/m2 is often used in clinical practice in patients perceived to be at risk of excess toxicity. To determine whether melphalan 200 mg/m2 and melphalan 140 mg/m2 are equally effective and tolerable in clinically relevant patient subgroups w
Excitatory amino acids are implicated in the development of neuronal cell damage following periods of reversible cerebral ischemia or insulin-induced hypoglycemic coma. To explore the importance of glutamate receptor activation in the posthypoglycemic phase, we exposed rats to 20 min of insulin-induced severe hypoglycemia. The rats were treated immediately after the hypoglycemic insult with four r
Due to their unique optical properties, III-V nanowires are promising candidates for the development of efficient solar cells, LEDs and nanoscaled lasers. The interaction of nanowires with fluorescent molecules is also of interest, as these nanostructures can act as nanoscaled optical fibers. The light emitted by a fluorophore close to a nanowire surface can in fact couple into the supported waveg
Background: Cervical cancer is the fourth most common cancer in women, and we recently reported human leukocyte antigen (HLA) alleles showing strong associations with cervical neoplasia risk and protection. HLA ligands are recognized by killer immunoglobulin-like receptors (KIRs) expressed on a range of immune cell subsets, governing their proinflammatory activity. We hypothesized that the inherit
Cytogenetic analysis using Giemsa banding technique was successful in 30 of the 49 adult patients with nonHodgkin lymphomas investigated. The results are correlated with previous findings in 48 non‐Hodgkin lymphoma patients studied by means of fine needle aspiration in our laboratory. As 8 patients were included in both series, the total number successfully investigated was 70. The success rate wi
Ossifying fibromyxoid tumor (OFMT) is a soft tissue tumor frequently displaying gene fusions, most of which affect the PHF1 gene. PHF1 encodes plant homeodomain finger protein 1, which is involved in various processes regulating gene transcription, including those orchestrated by the polycomb repressor complex 2. Here, a series of 37 OFMTs, including 18 typical, 9 atypical, and 10 malignant varian
A novel rhodium(iii) complex [RhIII(H2LtBu)Cl3] (1) (H2LtBu = 2,6-bis(5-tert-butyl-1H-pyrazol-3-yl)pyridine) containing a pincer type, tridentate nitrogen-donor chelate system was synthesized. Single crystal X-ray structure analysis revealed that 1 crystallizes in the orthorhombic space group Pbcn with a = 20.7982(6), b = 10.8952(4), c = 10.9832(4) Å, V = 2488.80(15) Å3, and eight molecules in the
Glucose supply from blood to brain occurs through facilitative transporter proteins. A near linear relation between brain and plasma glucose has been experimentally determined and described by a reversible model of enzyme kinetics. A conformational four-state exchange model accounting for trans-acceleration and asymmetry of the carrier was included in a recently developed multi-compartmental model
Chemotherapy resistance remains a major obstacle to successful treatment of ovarian cancer patients. Therefore, increased knowledge of underlying mechanisms and identification of predictive factors are of great importance. Standard treatment for ovarian carcinoma is surgery followed by platinum-based chemotherapy. In this study, we aimed to search for genes or genomic regions involved in platinum
MicroRNAs are small single stranded RNA molecules containing approximately 22 nucleotides and these play an important regulatory role in gene expression. MicroRNAs are found to be involved in several diseases and knowledge about their sequences can be an important tool in the foundation of novel treatment methods against diseases. Today, these small RNA molecules are mainly analyzed with qPCR and
Objectives To perform fine mapping of the PXK locus associated with systemic lupus erythematosus (SLE) and study functional effects that lead to susceptibility to the disease. Methods Linkage disequilibrium (LD) mapping was conducted by using 1251 SNPs (single nucleotide polymorphism) covering a 862 kb genomic region on 3p14.3 comprising the PXK locus in 1467 SLE patients and 2377 controls of Euro
Transmitted drug resistance (TDR) is a clinical and epidemiological problem because it may contribute to failure of antiretroviral treatment. The prevalence of TDR varies geographically, and its prevalence in Sweden during the last decade has not been reported. Plasma samples from 1,463 patients newly diagnosed with HIV-1 infection between 2003 and 2010, representing 44% of all patients diagnosed
Background: Acetyl Coenzyme A carboxylase beta (ACACB) is the rate-limiting enzyme in fatty acid oxidation, and continuous fatty acid oxidation in Acacb knock-out mice increases insulin sensitivity. Systematic human studies have not been performed to evaluate whether ACACB variants regulate gene expression and insulin sensitivity in skeletal muscle and adipose tissues. We sought to determine wheth
General Purpose Graphics Processing Units (GPGPUs) have become the prevalent processor for AI/ML and other large computational problems because parallel processing has not reached a hardware limit, unlike single-threaded processing. The goal of the thesis is to investigate the suitability of a novel SRAM architecture for implementation in a GPU without extensive GPU architecture changes. This arch
As the latest generation of wireless access technology called Fifth Generation (5G) New Radio (NR) evolves, computational efficiency is key to keep low cost and flexible deployments for vendors. Understanding how the Digital Signal Processing (DSP) load behaves in the digital units is one aspect to enable this efficiency. This thesis investigates how the DSP load in the base station behaves for a
