Spirulina fusiformis: A Food Supplement against Mercury Induced Hepatic Toxicity

Abstract: The protective effect of Spirulina fusiformis extract against mercury toxicity studied in Swiss albino mice. Animals treated with HgCl2 (5.0 mg/kg b.wt. i.p.) showed a significant elevation in lipid peroxidation level (LPO), aspartate amino transferase (AST) and alanine amino transferase (ALT) activity. However, a marked decline in serum alkaline phosphatase activity and reduced glutathione (GSH) content was recorded. Whereas, animals treated with Spirulina fusiformis extract (800 mg/kg b.wt. orally) before and after mercury intoxication showed a significant decrease in LPO level, AST and ALT activity and increase in serum alkaline phosphatase activity and GSH content. Spirulina fusiformis alone treatment did not alter reduced glutathione, AST, ALT and alkaline phosphatase activity but significantly diminishes the LPO level. Thus, the results obtained from the present study suggest that oral administration of Spirulina fusiformis extract provides protection against mercuric chloride induced toxicity in Swiss albino mice.

Centrality dependence of inclusive J/psi production in p-Pb collisions at root S-NN=5.02TeV

Abstract: We present a measurement of inclusive J/ψ production in p-Pb collisions at sNN=5.02(Formula presented.) TeV as a function of the centrality of the collision, as estimated from the energy deposited in the Zero Degree Calorimeters. The measurement is performed with the ALICE detector down to zero transverse momentum, pT, in the backward (−4.46 < ycms< −2.96) and forward (2.03 < ycms< 3.53) rapidity intervals in the dimuon decay channel and in the mid-rapidity region (−1.37 < ycms< 0.43) in the dielectron decay channel. The backward and forward rapidity intervals correspond to the Pb-going and p-going direction, respectively. The pT-differential J/ψ production cross section at backward and forward rapidity is measured for several centrality classes, together with the corresponding average pT and pT2 values. The nuclear modification factor is presented as a function of centrality for the three rapidity intervals, and as a function of pT for several centrality classes at backward and forward rapidity. At mid- and forward rapidity, the J/ψ yield is suppressed up to 40% compared to that in pp interactions scaled by the number of binary collisions. The degree of suppression increases towards central p-Pb collisions at forward rapidity, and with decreasing pT of the J/ψ. At backward rapidity, the nuclear modification factor is compatible with unity within the total uncertainties, with an increasing trend from peripheral to central p-Pb collisions.[Figure not available: see fulltext.]
