14-3-3 proteins are known to play a pivotal role in a diverse array of cellular events such as cell survival, apoptosis, and signal transduction. Numerous 14-3-3 ζ have been cloned and characterized from a host of eukaryotic organisms including human, plants, yeast, fruit fly and silkworm. However, no study on Spodoptera exigua 14-3-3ζ in conjunction with virus infection has so far been reported in insects. It appears that expression of Se14-3-3ζ was decreased starting 24 h post-SeNPV infection as SeNPV titers seemed to increase as evidenced by intense bands of SeNPV IAP3. Interestingly, confocal microscopic analysis revealed that Se14-3-3ζ is expressed at the apical side of the NPV-uninfected gut cells, whereas it was detected mainly in the nucleus of the NPV-infected cells. Thus, despite the biological significance of Se14-3-3ζ in S. exigua in conjunction with molecular interactions between SeNPV and S. exigua is unclear now, our data suggest that Se14-3-3 ζ protein plays a role to protect S. exigua from the infection or inhibit replication of SeNPV.

Mushrooms have been widely cultivated and consumed as foods and herbal medicines owing to their various biological properties. However, few studies have evaluated the anti-inflammatory effects of mushrooms. Here, we investigated the effects of mushroom extracts (MEs) on lipopolysaccharide (LPS)-induced inflammation in macrophages (RAW264.7 cells). First, we extracted MEs with either water or ethanol. Using LPS-treated RAW264.7 cells, we measured cell proliferation and NO production. Gene expression of tumor necrosis factor-α (TNF-α), interleukin (IL)-6 (IL-6), and IL-1β was assessed by RT-PCR, and protein abundance of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) and phosphorylation of p65 were determined by immunoblotting. MEs prepared using both water and ethanol inhibited LPS-induced inflammation in RAW264.7 cells. Nitric oxide (NO) levels induced by LPS were reduced by treatment with MEs. Isaria japonica Yasuda water extracts and Umbilicaria esculenta (Miyoshi) Minks ethanol extracts significantly decreased the mRNA expression of inflammation-related cytokine genes including TNF-α, IL-6, and IL-1β. Similarly, the protein abundance of iNOS and COX-2 was also decreased. The phosphorylation of p65, a subunit of nuclear factor-κB was at least partly suppressed by MEs. This study suggests that mushrooms could be included in the diet to prevent and treat macrophage-related chronic immune diseases.

Background : Cordyceps militaris has been an wonder drug to anti-aging efficacy and called the three main drugs with ginseng and deer antler from the past. Cordycepin, cordycepic acid (d-mannitol) and adenosine are known as functional ingredients in Cordyceps militaris. Among them, cordycepin, the representative component, has been reported as antimicrobial substance containing immune enhancement, anti-cancer and anti-inflammatory effects. Methods and Results : After Cordyceps militaris produced from different types of medium mixed with 10-fold volume of purified water, the mixture were extracted at 70±5℃ for a hour and that extracts re-extracted using ultrasonics wave for 30 minutes. Qualitative analysis of the index component was determined by using the Q-TOF (A quadrupole time-of-flight mass spectrometer), and quantitative analysis was performed by using HPLC (high-performance liquid chromatography) with Xselect HSS T3 column (2.1 X 100 mm, 2.5㎛, Waters, USA) and ultrapure water and acetonitrile as mobile phase A and B. Detection column temperature, injection volume and the flow rate were 35℃, 2 μL and 0.3 mL / minute respectively. The cordycepin content of Cordyceps militaris produced from medium mixed with vegetable and animal ingredients higher than single ingredient. Moreover, through a variety of analyzes by varying the type and content of the medium additives, the cordycepin in Cordyceps militaris produced from medium mixed with animal ingredients highest. Furthermore, the cordycepin content of a fruit body was higher than those of the a mycelium. Conclusion : These results provide a method for producing an high cordycepin content of Cordyceps militaris as functional food ingredient.

Treatment of spontaneous retroperitoneal hemorrhage (SRH) is mainly conservative. However, if intra-abdominal hypertension (IAH) or abdominal compartment syndrome (ACS) develops, the treatment strategy should be more aggressive. Surgical decompression has been the gold standard; however, it is very invasive and highly morbid. Thus, percutaneous catheter drainage (PCD) has been introduced as an alternative therapeutic option. We report on a case of successful PCD for prevention of progression of IAH to ACS in a patient with SRH after coronary stent implantation. This case showed that PCD can be an efficacious and safe method for treatment of IAH with impending ACS.
