Caesalpinia sappan L. (Caesalpiniaceae) is a medicinal plant which is used as a thirst quencher in southern part of India especially in Kerala. The present study was conducted to scientifically evaluate the effects of extracts of Caesalpinia sappan on phagocytic function of macrophages. In vivo effect of aqueous, ethanol and hexane extract of the plant at two doses (10mg/kg body weight and 25mg...

We measure and simulate numerically the Hanle effect and non-zero field level crossing signals in 85Rb and 87Rb atoms in a magnetic field at room temperature. Diode laser radiation from 4 mW cm−2 to 3.3 W cm−2 tuned to the D2 absorption line of each isotope excites atoms into all the excited-state hyperfine levels simultaneously inside the unresolved Doppler profile. Polarization fluorescence d...

The anthelmintic activity of thiabendazole syrup against Ancylostoma duodenale was investigated. Hookworm carriers (192) from the inhabitants of a village in Yamanashi Prefecture were treated under three dosage schedules. Before and after the administration, for the purpose of assessment, fecal examinations were performed by the thick smear method, the brine floatation method and quantitative d...

A current trend in drug research is the desire to obtain novel antimicrobials with plant origins as an alternative therapy and a means curb antimicrobial resistance. This study evaluated phytochemistry antibacterial activity of ethyl acetate leaf extract Newbouldia laevis. The laevis was cold extracted Ethyl acetate. for it phytochemical constituents using standard methods effect against some c...

T he scientific literature is replete with studies of the influence of weak magnetic fields on biological systems. Often motivated by alleged health hazards of the stray electromagnetic fields that accompany the distribution and use of electrical power, the majority of these articles report definite effects. However, in the relatively few cases in which independent replication has been attempte...

Nitrogen (N) isotope ratios ((15)N/(14)N) provide integrative constraints on the N inventory of the modern ocean. Anaerobic ammonium oxidation (anammox), which converts ammonium and nitrite to dinitrogen gas (N2) and nitrate, is an important fixed N sink in marine ecosystems. We studied the so far unknown N isotope effects of anammox in batch culture experiments. Anammox preferentially removes ...

[1] We investigate the relationship between solar irradiance and cosmogenic isotope variations by simulating with a flux transport model the effect of solar activity on the Sun’s total and open magnetic flux. As the total amount of magnetic flux deposited in successive cycles increases, the polar fields build up, producing a secular increase in the open flux that controls the interplanetary mag...
