Abstract:
The demand for high-quality silicone breast implants is rising. This was the first clinical study on implantation of Asian company-made silicone breast implants into Asian women. The authors report 4-year study data for BellaGel implants. This study is an ongoing 10-year study with 103 subjects undergoing augmentation or primary reconstruction with BellaGel implants. To assess effectiveness, rupture and capsular contracture rates were measured and Kaplan-Meier analysis was performed. Paired t-test was used to determine significant changes in breast dimensions. Safety assessment included evaluation of all adverse reactions. Average follow-up period was 5.9 years. Implant rupture and capsular contracture rate through 4 years were 0 percent and 2.3 percent, respectively. Capsular contracture rate was lower in the augmentation group (0.8%) than in the reconstruction group (5.6%). Among the adverse events, procedural pain was the only complication considered device-related, apart from capsular contracture. These 4-year data from the ongoing implant study support the effectiveness and safety of BellaGel implants.

Amides to Amines: LiAlH4 Reduction
Amide reduction requires two equivalents of the reducing agent, acting as a source of hydride ions. As shown in the figure, the reaction is initiated with a nucleophilic attack by the hydride ion at the carbonyl carbon to form a tetrahedral intermediate.
Nitriles to Amines: LiAlH4 Reduction
As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...
Acid Halides to Alcohols: LiAlH4 Reduction
The mechanism proceeds in three steps. First, the nucleophilic hydride ion attacks the carbonyl carbon of the acid halide to form a tetrahedral intermediate. Next, the carbonyl group is re-formed, and the halide ion departs as a leaving group, generating an aldehyde. A second nucleophilic attack by the hydride yields an alkoxide ion, which, upon protonation, gives a primary alcohol as...
