Differential expression of myrosinase gene families

In mature seeds of Brassica napus three major and three minor myrosinase isoenzymes were identified earlier. These myrosinases are known to be encoded by at least two different families of myrosinase genes, denoted MA and MB. In the work described in this paper the presence of different myrosinase isoenzymes in embryos, seedlings, and vegetative mature tissues of B. napus was studied and related t

Cell-specific and efficient expression in mouse and human B cells by a novel hybrid immunoglobulin promoter in a lentiviral vector

The expression of genes specifically in B cells is of great interest in both experimental immunology as well as in future clinical gene therapy. We have constructed a novel enhanced B cell-specific promoter (Igk- E) consisting of an immunoglobulin kappa (Igk) minimal promoter combined with an intronic enhancer sequence and a 30 enhancer sequence from Ig genes. The Igk- E promoter was cloned into a

Inhibitors of dipeptidyl peptidase IV: a novel approach for the prevention and treatment of Type 2 diabetes?

Inhibitors of the enzyme dipeptidyl peptidase IV (DPP IV) are of increasing interest to both diabetologists and the pharmaceutical industry alike, as they may become established as the next member of the oral antidiabetic class of therapeutic agents, designed to lower blood glucose and, possibly, prevent the progressive impairment of glucose metabolism in patients with impaired glucose tolerance a

Maternal Epstein-Barr virus and cytomegalovirus infections and risk of testicular cancer in the offspring: a nested case-control study

During recent decades the incidence of testicular cancer (TC) has increased rapidly around the world. Associated exogenous etiological factors might therefore be identifiable. We performed a case-control study nested within Finnish, Swedish and Icelandic maternity cohorts exploiting early pregnancy serum samples to evaluate the role of congenital or neonatal infections with Epstein-Barr virus (EBV

Acoustic modelling of earplugs

Experimental Two-Port data is used to model the acoustical behavior of three fundamentally different types of earplugs. It is shown that simple lumped models suffice to describe the acoustical behavior of the earplugs. Furthermore, it is shown that the measurement setup can advantageously be used to assess the acoustical properties of an arbitrary acoustical partition for a wide frequency range.

A risk haplotype of STAT4 for systemic lupus erythematosus is over-expressed, correlates with anti-dsDNA and shows additive effects with two risk alleles of IRF5

Systemic lupus erythematosus (SLE) is the prototype autoimmune disease where genes regulated by type I interferon (IFN) are over-expressed and contribute to the disease pathogenesis. Because signal transducer and activator of transcription 4 (STAT4) plays a key role in the type I IFN receptor signaling, we performed a candidate gene study of a comprehensive set of single nucleotide polymorphism (S

Collagen type II-specific monoclonal antibody-induced arthritis in mice - Description of the disease and the influence of age, sex, and genes

Transfer of collagen type H (CH)-specific monoclonal antibodies induces an acute form of arthritis (collagen type H antibody-induced arthritis, CAIA) in nave mice. Arthritis was induced using a pair of monoclonal antibodies M2139 and CIIC1, binding to J1 and C1(I) epitopes of CH, respectively. Thereafter, lipopolysaccharide injection was used to increase the incidence and severity of the disease.

Load-bearing increases new bone formation in impacted and morselized allografts

The effects of mechanical loading on the incorporation of morselized impacted grafts were addressed in this study. Twelve skeletally mature rabbits were surgically treated. Six rabbits received a proximal tibial joint replacement with a tibial tray and a load-bearing 25-mm long stem. The tibia was packed with fresh frozen, morselized, cancellous rabbit bone. No cement was used. In six other rabbit

Bioethical considerations for human nutrigenomics

This article gives an overview of the ethical issues in nutrigenomics; research and personalized nutrition. The principles of research ethics, i.e., autonomy, beneficence, nonmalfeasance, and justice, are challenged by rapidly growing cross-border research activities utilizing existing and upcoming biobanks for studies of the interaction of genes with diet on risk of common diseases. We highlight

Structure and expression of the gene encoding cystatin D, a novel human cysteine proteinase inhibitor

A new member of the human cystatin multigene family has been cloned from a genomic library using a cystatin C cDNA probe. The complete nucleotide sequence of a 4.3-kilobase DNA segment, containing a complete gene with structure very similar to those of known Family 2 cystatin genes, was determined. The novel gene, called CST4, is composed of three exons and two introns. It contains the coding info

Protein kinase B (c-akt) regulates hematopoietic lineage choice decisions during myelopoiesis

Hematopoiesis is a highly regulated process resulting in the formation of all blood lineages. Aberrant regulation of phosphatidylinositol-3-kinase (PI3K) signaling has been observed in hematopoietic malignancies, suggesting that regulated PI3K signaling is critical for regulation of blood cell production. An ex vivo differentiation system was used to investigate the role of PI3K and its downstream

The experience of older people of entering into the phase of asking for public home help - a qualitative study

The aim of this qualitative study was to explore older persons' (n = 28, 75-96 years of age) experience of becoming in need of public home help, their experience of participation and of having influence on the needs assessment procedure and the decisions made about public home help. A content analysis revealed a broad overarching category, labelled: experiencing discontinuity in life as a whole -

Massive feto-maternal hemorrhage: diagnosis by cardiotocography, Doppler ultrasonography and ST waveform analysis of fetal electrocardiography.

A 34-year-old healthy gravida 2 para 1 presented after an uncomplicated pregnancy at term with a 2-day history of diminished fetal movements. Fetal anemia was suspected by fetal heart rate monitoring and Doppler estimation of the fetal peak blood flow velocity of the middle cerebral artery. We were also fortunate to register pathological ST waveform changes of the fetal ECG indicating fetal hypoxi

Quasielastic He-3(e,e(')p)H-2 reaction at Q(2)=1.5 GeV2 for recoil momenta up to 1 GeV/c

We have studied the quasielastic He-3(e,e(')p)H-2 reaction in perpendicular coplanar kinematics, with the energy and the momentum transferred by the electron fixed at 840 MeV and 1502 MeV/c, respectively. The He-3(e,e(')p)H-2 cross section was measured for missing momenta up to 1000 MeV/c, while the A(TL) asymmetry was extracted for missing momenta up to 660 MeV/c. For missing momenta up to 150 Me
