Analisis Penentuan Kualitas Air Dan Status Mutu Sungai Progo Hulu Kabupaten Temanggung

Progo Hulu River is the main river in Progo watershed, Temanggung Regency. It was estimated that human activities have some important contributions in its water quality degradation, for example housings/settlement, agricultural, industry, etc. This research was aimed to analize Progo Hulu River which focused on (1) river water quality, (2) some factors that cause the different effects of each segment concentration, and (3) water quality status for every segment. The river water quality was observed in 12 sampling-points and then it compared with water quality standart according to the Government Act No. 82/2001. This research also describes water quality status used STORET and Pollution Index method based on Ministry Decree No. 115/2003. As result, Fecal Coliform become a dominant parameter that caused pollution in first class water quality, whereas Ammonia and Fecal Coliform caused pollution in second, third, and fourth class water quality with a main pollution source from domestic and ranch wastes. Besides, water quality status showed it has been modaretely polluted in first class water quality status and lightly- modaretely polluted in second, third, and fourth class water quality status

Fluorescent Recognition of Zn²⁺ by Two Diastereomeric Salicylaldimines: Dramatically Different Responses and Spectroscopic Investigation

Fluorescence responses of two BINOL-based diastereomeric salicylaldimines toward a variety of metal cations have been studied in methanol solution. It is revealed that both compounds show great fluorescence enhancements in the presence of Zn²⁺ but not with any other metal ions. Moreover, these two diastereomers exhibit dramatically different responses toward Zn²⁺ under the same conditions. That is, one can produce much stronger fluorescence enhancement also at a longer wavelength than the other. This fluorescence recognition of Zn²⁺ also shows distinctive color changes under a UV lamp. Mass and NMR spectroscopic analyses have been used to study the mechanism, which indicates the formation of 2+<i>n</i>Zn²⁺ complexes (<i>n</i> = 2, 3). This work has shed new light on the mechanism of an enantioselective fluorescent recognition of chiral amines promoted by Zn²⁺

Planar Chiral Ferrocene Cyclopalladated Derivatives Induce Caspase-Dependent Apoptosis and Antimetastasis in Cancer Cells

A series of planar chiral ferrocene cyclopalladated compounds were synthesized and characterized. The absolute configurations of four compounds were determined by single-crystal X-ray analysis. The cytotoxic activities of the synthesized compounds and cisplatin exhibited different inhibition potencies on the viability of human liver, breast, and colon cancer cell lines. The dinuclear compound <b>7</b> was 16-fold more potent than cisplatin in hepatoma cells. Compound <b>7</b> was also more effective than cisplatin in the inhibition of hepatoma cell metastasis. Flow cytometry analysis and caspase activity assays indicated that compound <b>7</b> exerted antiproliferative activity in cancer cells through the induction of caspase-dependent apoptosis

Fluorescent Binary Ensemble Based on Pyrene Derivative and Sodium Dodecyl Sulfate Assemblies as a Chemical Tongue for Discriminating Metal Ions and Brand Water

Enormous effort has been put to the detection and recognition of various heavy metal ions due to their involvement in serious environmental pollution and many major diseases. The present work has developed a single fluorescent sensor ensemble that can distinguish and identify a variety of heavy metal ions. A pyrene-based fluorophore (<b>PB</b>) containing a metal ion receptor group was specially designed and synthesized. Anionic surfactant sodium dodecyl sulfate (SDS) assemblies can effectively adjust its fluorescence behavior. The selected binary ensemble based on <b>PB</b>/SDS assemblies can exhibit multiple emission bands and provide wavelength-based cross-reactive responses to a series of metal ions to realize pattern recognition ability. The combination of surfactant assembly modulation and the receptor for metal ions empowers the present sensor ensemble with strong discrimination power, which could well differentiate 13 metal ions, including Cu²⁺, Co²⁺, Ni²⁺, Cr³⁺, Hg²⁺, Fe³⁺, Zn²⁺, Cd²⁺, Al³⁺, Pb²⁺, Ca²⁺, Mg²⁺, and Ba²⁺. Moreover, this single sensing ensemble could be further applied for identifying different brands of drinking water

Discrimination of Metalloproteins by a Mini Sensor Array Based on Bispyrene Fluorophore/Surfactant Aggregate Ensembles

Fluorescent sensor arrays with pattern recognition ability have been widely used to detect and identify multiple chemically similar analytes. In the present work, two particular bispyrene fluorophores containing hydrophilic oligo­(oxyethylene) spacer, <b>6</b> and <b>4</b>, were synthesized, but one is with and the other is without cholesterol unit. Their ensembles with cationic surfactant (CTAB) assemblies realize multiple fluorescence responses to different metalloproteins, including hemoglobin, myoglobin, ferritin, cytochrome <i>c</i>, and alcohol dehydrogenase. The combination of fluorescence variation at monomer and excimer emission of the two binary sensor ensembles enables the mini sensor array to provide a specific fingerprint pattern to each metalloprotein. Linear discriminant analysis shows that the two-ensemble-sensor-based array could well discriminate the five tested metalloproteins. The present work realizes using a mini sensor array to accomplish discrimination of complex analytes like proteins. They also display a very high sensitivity to the tested metalloproteins with detection limits in the range of picomolar concentration
