Introduction Omoglymmius Ganglbauer, 1891 is the most speciose genus of Rhysodidae ( Coleoptera), almost cosmopolitan, but absent from Madagascar, New Zealand, and South America. Excellently revised Omoglymmius and established eleven subgenera to classify the congeneric species. The nominotypical subgenus is the largest with 97 species (,, ). However, in the fauna of East Asia, only two species in the subgenus Omoglymmius had been recorded before this study, namely O. Str.) sakuraii (Nakane, 1973) (China (Taiwan), Japan, Vietnam) and O. Str.) laticeps Bell, 1977 (Bhutan, India).

In this paper, a new species, O. Str.) wukong sp. N., is described and illustrated from Xizang Autonomous Region, China. The new species is compared to the two related species, with some selected and important morphological characters presented in a table. Materials and methods Specimens were relaxed and softened in a hot saturated solution of potassium hydroxide for 4 minutes (for mounted dry specimens) or 8 minutes (for alcohol-preserved specimens), and then transferred to distilled water to rinse the residual potassium hydroxide off and stop any further bleaching.
The softened specimens were placed in glycerine and dissected to observe morphological details. After examination, the body parts were mounted on a glass slide with Euparal Mounting Medium for future studies.
Habitus photographs were taken using a Canon macro photo lens MP-E 65mm on a Canon 550D. Observations, photographs, and measurements of morphological details were performed using a Zeiss Axio Zoom.V16 motorized stereo zoom microscope with a Zeiss AxioCam MRc 5. Photographs in Figure were taken with an Olympus BX53 microscope with an Olympus DP73 camera. The final deep focus images were created with Zerene Stacker 1.04 stacking software. Adobe Photoshop CS6 was used for final processing.

Measurements are averages taken from five specimens. The morphological terminology follows, ). Rhysodid beetles are treated as an independent family, following the publications of,, and.

Figure 1 Pathogenesis of Inflammatory Bowel Disease. Normal epithelium, with its highly evolved tight junctions and products of goblet-cell populations, most notably trefoil peptides and mucin glycoproteins, provides an effective barrier against luminal agents. The integrity of the barrier may be compromised by genetic variations in key molecular determinants, a diminished reparative response to injury, or exogenous agents, such as nonsteroidal antiinflammatory drugs. Chronic, recurrent intestinal inflammation appears to result from stimulation of the mucosal immune system by products of commensal bacteria in the lumen. Antigens from dietary sources may also contribute.
Stimulation may occur as a result of the penetration of bacterial products through the mucosal barrier, leading to their direct interaction with immune cells, especially dendritic cells and lymphocyte populations, to promote a classic adaptive immune response. Alternatively, bacterial products may stimulate the surface epithelium, possibly through receptors that are components of the innate immune-response system; the epithelium can, in turn, produce cytokines and chemokines that recruit and activate mucosal immune cells. Activation of classic antigen-presenting cells, such as dendritic cells, or direct stimulation through pattern-recognition receptors promotes the differentiation of type 1 helper T cells (Th1) in patients with Crohn's disease (shown here) or, possibly, atypical type 2 helper T cells in patients with ulcerative colitis. The stereotypical products of Th1 promote a self-sustaining cycle of activation with macrophages.
In addition to producing the key cytokines that stimulate Th1 (interleukin-12, interleukin-18, and macrophage migration inhibitor factor), macrophages produce a mix of inflammatory cytokines, including interleukin-1, interleukin-6, and most notably tumor necrosis factor, which target a broad variety of other types of cells. The latter include endothelial cells, which then facilitate the recruitment of leukocytes to the mucosa from the vascular space, as well as fibroblasts and epithelium, modulating their functional properties. Most important, these functions may be altered either by genetically determined variants, as exemplified by germ-line mutations in the gene encoding NOD2, the product of the IBD1 locus, in some patients with Crohn's disease, or by environmental factors. Figure 2 Common Cellular Pathways of Activation in Inflammatory Bowel Disease.
Activation of the protean transcriptional regulatory factor nuclear factor-κB (NF-κB) is a common pathway central to cell activation and the production of diverse inflammatory mediators, including a variety of cytokines and chemokines. It also modulates resistance to programmed cell death (apoptosis). Several inflammatory factors implicated in inflammatory bowel disease activate NF-κB by eventually stimulating an intermediate kinase such as NF-κB–inducing kinase (NIK) or mitogen-activated protein kinase kinase 1 or 3 (MEKK1 or MEKK3) or by binding to receptor-interacting protein 2. These lead to phosphorylation of the inhibitor of κB kinase (IKK) and subsequent dissociation of NF-κB (itself a dimer). Download Vray Sketchup Pro 2014 Free on this page. NF-κB then travels to the nucleus, where it can effect gene transcription.
The phosphorylated constituents are subject to degradation by proteosomes after ubiquitination. The spectrum of mediators that activate this pathway includes inflammatory cytokines such as interleukin-1 and tumor necrosis factor (TNF), which bind to their respective cell-surface receptors, as well as microbial products such as lipopolysaccharide, which bind to cell-surface receptors that are members of the toll-like receptor family of pattern-recognition receptors. The pathway is also activated by NOD2 (also referred to as CARD 15), an intracytoplasmic receptor that is activated by the entry, through mechanisms yet to be defined, of bacterial lipopolysaccharide into the cytoplasm. NOD2 is the product of the IBD1 gene; germ-line mutations, which are present in many patients with Crohn's disease, appear to alter the activation of the NF-κB pathway.
