1. Hybridization and Evolution in the Genus Pinus
Abstract : Gene flow and hybridization are pervasive in nature, and can lead to different evolutionary outcomes. They can either accelerate divergence and promote speciation or reverse differentiation. The process of divergence and speciation are strongly influenced by both neutral and selective forces.

2. The roles of demography and natural selection in shaping genome-wide variation of Norway spruce
Abstract : Understanding the relative contribution of genetic drift, natural selection, and mutation to genetic variation, and quantifying adaptive evolution and the effects of natural selection in species are enduring goals of evolutionary genetics. Norway spruce (Picea abies) is one of the most important conifer species that dominates from both an ecological and economical point of view in many boreal ecosystems. READ MORE

3. New molecular markers in mantle cell lymphoma : studies of cannabinoid receptors, 5-lipoxygenase and SOX11
Abstract : Mantle cell lymphoma (MCL) is a malignant B-cell lymphoma that accounts for 5-10% of all lymphomas and tends to occur in older adults with a higher incidence in males. The genetic hallmark of this neoplasm is the t(11;14) translocation which results in overexpression of nuclear cyclin D1. READ MORE

4. Immune modulation of macrophages by the meningococcal surface protein NhhA
Abstract : Functional immune modulation of macrophages play important role during bacterial infection. Neisseria meningitidis, a gram-negative diplococcal bacterium, is the leading cause of bacterial meningitis and fatal septic shock. However, it is also a commensal bacterium that colonizes the nasopharynx of healthy individuals asymptomatically. READ MORE

5. Macrophage programming and host responses to bacterial infection
Abstract : Macrophages are dynamic, plastic, and heterogeneous immune cells that play an important role in host immune defense against bacterial infection. Various bacterial pathogens, such as Neisseria meningitidis and Mycobacterium tuberculosis, can modulate host immune responses by interfering with macrophage differentiation and polarization.
