Objective: To investigate the safety and feasibility of steroids minimization immunosuppressive regimen in liver transplantation.
Methods: One hundred and sixteen patients in line with the selecting criteria from January 2005 to June 2008 were divided into three groups according to the withdrawal of steroids: 40 cases in 3 months withdrawal group, 40 cases in 7 d withdrawal group and the other 36 cases in 24 h withdrawal group. The difference of recipients' survival, infection, acute rejection and steroids resistant acute rejection, wound healing, recurrence of HBV and hepatocellular cell (HCC), new on-set of diabetes, hyperlipidemia and hypertension between the three groups were compared.
Results: The difference of recipients' survival, acute rejection including steroids resistant acute rejection, recurrence of HBV and HCC, hyperlipidemia between the three groups were not significant (P > 0.05), the incidence of wound un-healing and hypertension in 24 h withdrawal group was significantly lower than that in the other 2 groups (P < 0.05), the incidence of infection and new on-set diabetes in 24 h withdrawal group and 7 d withdrawal group was significantly lower than that in 3 months withdrawal group (P < 0.05).
Conclusion: Steroids minimization immunosuppressive strategy is safe and feasible in liver transplantation field, it will significantly reduce the steroids related complications without increasing the risk of rejection.

Introduction: The Friedreich Ataxia Rating Scale-Activities of Daily Living (FARS-ADL) is a validated and highly utilized measure for evaluating patients with Friedreich Ataxia. While construct validity of FARS-ADL has been shown for spinocerebellar ataxia (SCA), content validity has not been established.
Methods: Individuals with SCA1 or SCA3 (n = 7) and healthcare professionals (HCPs) with SCA expertise (n = 8) participated in qualitative interviews evaluating the relevance, clarity, and clinical meaningfulness of FARS-ADL for assessment of individuals with SCA.

The [4+2] Diels-Alder cycloaddition reaction between 2,5-DMF (1) and ethylene derivatives (2a-h) activated by electron-withdrawing groups has been studied at the density functional theory levels using a panoply of tools to unravel the reaction mechanisms. From the analysis of the reactivity indices, 2a-h behave as electrophiles while 1 as nucleophile, and the activation of the double bond of ethylene increases its electrophilicity, which is accompanied by an enhancement of the polarity of the reaction. The activation Gibbs free energy decreases linearly as a function of this increase of polarity, as estimated by the electrophilicity difference between the reactants.

The development of catalytic methods for the synthesis of enantiopure saturated heterocycles has been a long-standing challenge in asymmetric catalysis. We describe the first highly enantioselective palladium-catalyzed βC(sp)-H arylation and olefination of lactams for the preparation of various chiral N-heterocycles bearing quaternary carbon centers. The presence of strongly electron-withdrawing groups on the chiral bifunctional MPAThio ligand is crucial to the reactivity of weakly coordinating lactams.

Aim And Objective: It is well established that 4H-pyran derivatives hold a significant position in synthetic organic chemistry due to their diverse biological and pharmacological properties. This work aims to introduce a novel synthetic pathway for highly functionalized 4H-pyran derivatives, achieved through a 1,4-Michael addition followed by a cascade cyclization. This reaction is catalyzed by LiOH·H2O under ultrasonic irradiation in water, offering an efficient and environmentally friendly approach.

The urea oxidation reaction (UOR) is characterized by a lower overpotential compared to the oxygen evolution reaction (OER) during electrolysis, which facilitates the hydrogen evolution reaction (HER) at the cathode. Charge distribution, which can be modulated by the introduction of a heterostructure, plays a key role in enhancing the adsorption and cleavage of chemical groups within urea molecules. Herein, a facile all-room temperature synthesis of functional heterojunction NiCoS/CoMoS grown on carbon cloth (CC) is presented, and the as-prepared electrode served as a catalyst for simultaneous hydrogen evolution and urea oxidation reaction.
