Title: Synthesis of Bisnaphthyl Based Thiol Stabilized Gold Nanoparticles Authors: MAIMOONA KHATOON; ASRA MUSTAFA; MUHAMMAD RAZA SHAH Abstract: Bisnaphthyl based thiol stabilized gold nanoparticles were synthesized by the chemical reduction of corresponding precursor, obtained from Au(III) salt with thiol ligand 4. The organothiol ligand 4 were prepared from 1,1′-binaphth-2,2′-ol in three steps. Furthermore, the photophysical activity of these Au-NPs was also determined.

Title: Determination of the Mineral Compositions of in Six Beans by Microwave Digestion with Inductively Coupled Plasma Atomic Emission Spectrometry Authors: QINGHUA YAN; LI YANG; SHUYANG CHEN; XI LIU; XIAOQIN MA Abstract: In the study, microwave digestion procedure optimized was applied for digesting beans. Nineteen mineral element concentrations were determined by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The result indicated detection limits for the 19 elements were less than 0.0998, and relative standard deviations were 1.01%~5.02% for all the elements, and recoveries were 90.89%~104.55% by adding standard recovery experiment. The study showed the beans selected were abundant in mineral element contents in human nutrition, determination mineral element contents by ICP-AES with microwave digestion technology were a lot of merits of small environmental pollution, fast and accurate determination result, which could satisfy the examination request of bean samples. The results provided evidence that the six beans were a good source of K, P, Mg and Ca. This study is to give important reference value to people due to individual differences by adjusting the dietary to complement the different mineral elements.

Title: Effects of Whole Flower and Fractions of Ixora coccinea Linn. on Cardiovascular System: A Preliminary Report Authors: ATIQ-UR-RAHMAN; SYED INTASAR HUSAIN; VERSIANI, MUHAMMAD ALI; AMBREEN IKRAM; SALMAN KHALIDAHMED Abstract: Ixora coccinea is used to treat various ailments in traditional medicine. The extract of whole flower and various fractions were studied in to Langendorff’s male guinea pig heart to explore the therapeutic/toxic potential Perfusion pressure (PP), left ventricular pressure (LVP), dP/dt, heart rate calculated from ECG (HR-ECG) and LVP (HR-LVP) were focused in acute and sustained phases. All the fractions showed concentration-dependant effects. The extract of whole flower (IXFM-WF) increased PP, decreased HR- ECG and HR-LVP , LVP showed initial decrease followed by increase in acute phase and decrease in sustained phase and dP/dt showed no significant change. The ethyl acetate fraction (IXF₃) increased the PP significantly, decreased LVP, HR-LVP and HRECG and dP/dt significantly. The methanol-benzene fraction (IXF-MMB) increased PP, decreased HR-LVP, HR-ECG whereas LVP was increased in acute phase and decreased in sustained phase, dP/dt(min) was increased in both phases. The methanolic fraction(IX-F₄M₂) increased PP significantly in acute phase, LVP was decreased in acute phase initially followed by sharp decrease in sustained phase, LVP was not affected prominently, HR-LVP showed decrease in both the phases, HR-ECG showed initial increase followed by sharp decrease, dP/dt(max) was increased in acute phase where as dP/dt(min) was decreased prominently. The aqueous fraction (IXFMAq) showed sharp increase in PP, decrease in LVP, HR-ECG and HR-LVP and no significant effect on dP/dt. The extract of whole flower and IXF₃, IXFMMB and IXFMAq are cardio-toxic and stopped the heart completely which took 30 seconds to 1.0 hour to recover partially. Whereas, IXF₄M₂did not block the heart at any administered dose.

Title: An Efficient Eco-Friendly Synthesis of Indole-Mannich Base Authors: KHALID MOHAMMED KHAN; FAZAL RAHIM; NIDA AMBREEN; MUHAMMAD TAHA; SAROSH IQBAL; SYED MOAZZAM HAIDER; SHAHNAZ PERVEEN Abstract: An efficient and simplified protocol for three component Mannich reaction of indoles in water without using any catalyst is described. Different functionalized indole Mannich base synthesized in relatively short time with moderate to good yields. The advantages of this methodology are higher selectivity, simplicity, and shorter reaction time. To the best of our knowledge this is the first green protocol for indole Mannich base reaction.
