We examined the effect of chronic (15 days) administration of antihypertensive agents, from different pharmacologic classes, on arterial pressure (AP) and heart rate variability in two-kidney, one-clip hypertensive (2K1C) rats. The 2K1C rats received by gavage one of the following: water, ramipril, losartan, atenolol, amlodipine, or hydrochlorothiazide. Sham-operated normotensive rats received ...
A new heteroditopic chemosensor based on the 1,3-alternate conformation of thiacalix[4]crown shows a ratiometric fluorescence response towards Hg(2+) ions. Further, a negative allosteric behaviour between Hg(2+)/Li(+) ions is observed. Thus, metal ion exchange triggers a Hg(2+)/Li(+) switchable fluorescent chemosensor.
Abstrak Bagi manusia, air adalah hal yang sangat penting untuk mendukung aktivitas manusia setiap hari. Tanpa adanya udara, tidak mungkin bisa bertahan dalam menjalani kehidupan. AMDK ada di Pekanbaru saat ini sudah bermacam-macam serta terkontaminasi oleh udara kotor ada. Hal sejalan dengan kota cukup padat penduduk dan juga secepatnya kendaraan meningkat. Adapun tujuan penelitian mengetahui ...
پژوهش صورت پذیرفته که در این رساله ارائه گردیده است در رابطه با بکارگیری شیمی کوئوردیناسیون و شیمی ابر مولکولی در زمینه ی پلیمرهای کئوردیناسیونی می باشد. علاوه بر آن تغییرات جزئی در مواد واکنش دهنده و روند واکنش سبب ایجاد اثرات قابل توجهی بر روی محصولات گردیده است که این اثرات نیز مورد مطالعه قرارگرفته اند. در نهایت به اثر هالیدها برروی انباشتگی کریستالی پلیمرهای کوئوردیناسیونی جیوه و کمپلکس ها...
Development of Cyanine 813@Imidazole-Based Doped Supported Devices for Divalent Metal Ions Detection
A NIR cyanine@imidazole derivative Cy1 was synthesized and evaluated as a metal ion sensor in solution. shown to be very sensitive all ions tested, presenting blue shift the absorption from 668 nm 633 nm, followed by change colour pale green with Zn2+, Cd2+, Co2+, Ni2+ Hg2+ ions. Despite absorption, decrease at (with colourless), well quenching emission intensity 785 were observed for Cu2+ The ...
8-Hydroxyquinoline benzoates as highly sensitive fluorescent chemosensors for transition metal ions.
[graph: see text] 8-Hydroxyquinoline benzoates were developed as a new set of 8-HQ derivatives for highly sensitive fluorescent chemosensors for transition metal ions. A prominent fluorescence enhancement was found in the presence of transition metal ions such as Hg2+ and Cu2+, and this was suggested to result from the suppression of radiationless transitions from the npi state in the chemosens...
5. Anaerobic incubation caused an inhibition of synthesis only in the presence of oxaloacetate; no inhibition was observed anaerobically in the presence of a-oxoglutarate plus malonate. 6. Hg2+ and arsenate almost completely abolished fatty acid synthesis; cyanide and 2:4-dinitrophenol caused a moderate (30-70%) inhibition, while azide and fluoride were without effect. 7. The implication of the...
BACKGROUND Molecular signatures may become of use in clinical practice to assess the prognosis of breast cancers. However, although international consensus conferences sustain the use of these new markers in the near future, concerns remain about their degree of discordance and cost-effectiveness in different international settings. The present study aims to validate Ki67 as prognostic factor i...
