Background and Objectives: Previous studies have indicated that lithium may increase the level of the brain-derived neurotrophic factor (BDNF), which in turn improves the recovery of patients with stroke. In this controlled trial we evaluated the effect of lithium on BDNF serum level in patients with ischemic stroke. Methods: In this randomized controlled...
The effects of gentamicin, lithium and combination of these drugs on ultrastructural morphology of rat submandibular glands were studied. Daily intraperitoneal injection of 40 mg/kg of gentamicin which causes chronic salivary gland toxicity, led to a marked decrease in gland's dry weight and total protein concentration but did not affect DNA content. Electron micrograph (EM) of submandibular ...
Lithium is an element which has been used as salts of chloride or carbonate for many years in the treatment of some psychological disorders such as mania, bipolar or schizophrenic diseases. Chronic application of lithium may induce some serious nephropathies such as natriuresis, renal tubular acidosis, tubulointerstitial nephritis progression to progressive chronic kidney disease and hypercalce...
Deprotonation of [U(Tren(TIPS))(NH2)] (1) [Tren(TIPS) = N(CH2CH2NSiPr(i)3)3] with organoalkali metal reagents MR (M = Li, R = Bu(t); M = Na-Cs, R = CH2C6H5) afforded the imido-bridged dimers [{U(Tren(TIPS))(μ-N[H]M)}2] [M = Li-Cs (2a-e)]. Treatment of 2c (M = K) with 2 equiv of 15-crown-5 ether (15C5) afforded the uranium terminal parent imido complex [U(Tren(TIPS))(NH)][K(15C5)2] (3c), which c...
The ternary compound Ba Li Sn was obtained by slow cooling of a stoichiometric mixture of the elements that was heated at 800 8C 3 4 8 3 ̊ ̊ for 2 days. Its structure (monoclinic, C2/m, Z52, a518.549(1), b56.685(1), c56.792(1) A, V5833.2(2) A , R /wR 5 4.03/11.33%) 1 2 1 102 contains one-dimensional chains of [Sn ] made of edge-sharing cyclodecane-like units in their ‘all-chair’ conformations. Th...
The mixed bimetallic title compound, [InLi(CH3)2(C7H7O)2(C6H16N2)] or [(tmeda)Li-μ-(4-MeC6H4O)2InMe2] (tmeda is N,N,N',N'-tetra-methyl-ethylenedi-amine), exhibits a four-membered LiO2In ring core via bridging 4-methyl-phenolate groups. The Li and In atoms are in distorted tetra-hedral N2O2 and C2O2 bonding environments, respectively. The Li atom is further chelated by a tmeda group, yielding a ...
The B(6)Li(8) cluster is a symmetrical 3D complex whose high stability can be understood through the Wade rule and aromaticity. A new mechanism of B-Li chemical bonding is proposed. Importantly, B(6)Li(8) is predicted to be a promising candidate for hydrogen storage material with gravimetric density reaching up to a theoretical limit of 24%.
