The technology of removing phosphorous, considered as one of the most important control nutrients causing eutrophication in various water bodies, have been investigated by many researchers. Recently, phosphorous crystallization process is emerging as a new technology for phosphorous removal. In this study, waste oyster shells which can be easily obtained from the ocean, were used as a seed crystal, and their effects of several physical/chemical factors on the phosphorous removal efficiencies were examined by batch tests. Ca^(2+) and pH affected phosphorous crystallization process using waste oyster shells. As alkalinity of wastewater increased, phosphorous removal efficiencies gradually decreased. Phosphorous removal efficiencies were increased, as specific area and contact efficiency per unit area of waste oyster shells were increased. In case of high temperature, phosphorous crystallization process was rapidly advanced and phosphorous removal efficiencies were increased. Depending on X-ray diffraction analysis, it was showed that generation materials extracted from the surface of waste oyster shells with short reaction time were dominated by CaHPO₄ ·2H₂O, but progressed to Ca_(5)(OH)(PO₄)₃.

Dyeing has always had a pressing need for techniques that allow economical pretreatment for color removal in wastewater. The effectiveness of adsorption for color removal from dyeing wastwater has made it an ideal alternative to other expensive treatment options. This study deals with an investigation on four waste resources locally available in dyeing wastewater treatment for color removal. Peat, bentonite, slag and fly ash were utilized for this study and their performance evaluated against that of granular activated carbon. Color of dyeing wastewater was high removed in peat, bentonite and slag except for fly ash. In point of recycling, if waste resources substituted for a valuable adsorbent such as granular activated carbon, peat, bentonite and slag could look forward to an expected economical effect.

The Polyimide thin films based on PMDA and 4,4'-DDE were fabricated by VDPM, and their heat resistance characteristics were invastigated by TGA(Thermogaravimetry Analyzer). It was found that deposition rate decreased with increasing substrate temperature and the thin films were not fabricated over the substrate temperature of 70℃. T_TG of 5% weight loss temperature is 565℃, 397℃ and 210℃ at the substrate temperature of 20℃, 40℃ and 70℃, respectively. It is realized that the endurace temperature for 20,000 hour of thin films fabricated at 20℃ and 40℃ is 230℃ and 200℃, respectively.

In Anti-inflammatory effects, Chinese Carthami Semen extract group showed significant decrease at 150 and 180 minutes after inducing paw-edema in comparison with control group. 3. In the method of adjuvant arthritis, orally administered for 21 days, Korean Carthami Semen extract group showed significant inhibition of the hind paw edema after 1 day and 21 days. Whereas Chinese Carthami Semen extract group showed some reduction, but the results didn's show significant decrease. 4. In the level of leucocytes count, Korean and Chinese Carthami Semen extract group showed significant decrease in comparison with control group. And in the level of total protein. CRP and glucose, Korean and Chinese Carthami Semen extract group didn't showed significant change in comparison with control group.

Objectives : The present study has been undertaken to investigate the effects of Ginseng Radix on prevention of osteoporosis in ovariectomized rats. Methods : In this experiment, the rats were ovariectomized. Rats were administered by 2 kinds of medicine, Estradiol, Ginseng Radix. The levels of bone mineral density, osteocalcin, ALP, phosphorus, calcium in serum, deoxypyridinoline in urine, calcium, phosphorus, ash weight of bone, body weight and uterus weight were measured. Results : The levels of spinal bone mineral density was significantly increased in comparison with OVX group at 8 weeks in Ginseng Radix group. The levels of serum didn t show significant change in comparison with OVX group in Ginseng Radix group. The levels of urine deoxypyridinoline showed significant decrease in comparison with OVX group in Ginseng Radix group. The levels of femoral and fibula-tibial ash weight didn t show significant increase in comparison with OVX group in Ginseng Radix group. The levels of femoral and fibula-tibial calcium showed significant increase in comparison with OVX group in Ginseng Radix group.

<P>Kinase suppressor of RAS1 (KSR1) is a scaffold protein implicated in RAS-mediated RAF activation. However, the molecular function of KSR in papillary thyroid cancer (PTC) is unknown. Thus, this study aimed to characterize the role of KSR1 in patients with PTC. qRT-PCR and immunohistochemistry (IHC) revealed inter-tumor heterogeneities in the expression of KSR1 in PTC tissues. Interestingly, BRAFV600E-positive PTC showed higher <I>KSR1</I> mRNA expression than BRAFV600E-negative PTC (<I>P</I><0.001). Gene Set Enrichment Analysis (GSEA) using public repositories showed that high KSR1 expression coordinately upregulated Notch signaling (nominal <I>P</I>=0.019, false discovery rate (FDR) <I>q</I>-value=0.165); this finding was supported by GeneNetwork analysis, indicating that <I>KSR1</I> expression is positively correlated with <I>NOTCH1</I> expression (<I>ρ</I>=0.677, <I>P</I>=6.15×10<SUP>−9</SUP>). siRNA against KSR1 (siKSR1) significantly decreased ERK phosphorylation induced by BRAFV600E, resulting in reduced expression of <I>NOTCH1</I> and <I>HES1</I>, targets of Notch signaling. GSEA revealed that high KSR1 expression was also associated with downregulation of genes related to oxidative phosphorylation (OxPhos). Consistent with this, electron microscopy showed that PTCs with high KSR1 expression exhibited structural defects of the mitochondrial cristae. Furthermore, siKSR1-transfected BCPAP and 8505C cells generated fewer colonies in colony-forming assays. In addition, GSEA showed that high expression of KSR2 and connector enhancer of KSR1 (CNKSR1) also coordinately upregulated Notch signaling (KSR2: nominal <I>P</I>=0.0097, FDR <I>q</I>-value=0.154 and CNKSR1: nominal <I>P</I><0.0001, FDR <I>q</I>-value=0.00554), and high CNKSR2 was associated with downregulation of the OxPhos gene set (nominal <I>P</I><0.0001, FDR <I>q</I>-value <0.0001). In conclusion, KSR1 is coordinately regulated with Notch signaling and OxPhos in PTC, because its scaffold function might be required to sustain the proliferative signaling and metabolic remodeling associated with this type of cancer.</P>

In this study, wormorm-like polymeric micelles were construted from poly(L-lactic acid)-b-poly(ethyelen glycol) (PLLA-b-PEG) block copolymers via worm-like (or cylindrical) self- assembly that consisted of a relatively long PLLA block ($M_n$ 7K Daltons) at the core and a relatively short PEG block ($M_n$ 2K Daltons) as the shell. Several cancer-targeting moieties (such as folate, cobalamin, and cyclic arginine-glycine-aspartic (RGD) peptide) were chemically coupled with the succinylated or maleimided PEG block of PLLA-b-PEG to act as a cancer cell-specific targeting ligand for breast cancer. The worm-like micelles with muplite cancer cell-specific ligands proved to be successful in recognizing different breast cancer cells at once. This has the potential to aid in cancer-specific drug delivery and to be used as an effective treatment for breast cancer.
