We report the first total synthesis of (+)-granatumine A, a limonoid alkaloid with PTP-1B inhibitory activity, in 10 steps. Over the course of this study, two key methodological advances were made: a cost effective procedure for ketone alpha,beta-dehydrogenation using allyl-Pd catalysis, and a Pd-catalyzed protocol to convert epoxyketones to 1,3-diketones. The central tetrasubstituted pyridine is formed by a convergent Knoevenagel condensation and carbonyl-selective electrocyclization cascade, which was followed by a direct transformation of a 2<i>H</i>-pyran to a pyridine. These studies have led to the structural revision of two members of this family.

The Relationship

Abstract An effective procedure to determine the Burn-In acceleration factors for 130nm and 90 nm processes are discussed in this paper. The relationship among yield, defect density, and reliability, is well known and well documented for defect mechanisms. In particular, it is important to determine the suitable acceleration factors for temperature and voltage to estimate the exact Burn- In conditions needed to screen these defects. The approach in this paper is found to be useful for recent Cu-processes which are difficult to control from a defectivity standpoint. Performing an evaluation with test vehicles of 130nm and 90nm technology, the following acceleration factors were obtained, Ea&gt;0.9ev and β (Beta)&gt;-5.85. In addition, it was determined that a lower defect density gave a lower Weibull shape parameter. As a result of failure analysis, it is found that the main failures in these technologies were caused by particles, and their Weibull shape parameter “m” was changed depending of the related defect density. These factors can be applied for an immature time period where the process and products have failure mechanisms dominated by defects. Thus, an effective Burn-In is possible with classification from the standpoint of defect density, even from a period of technology immaturity.

Outcome Evaluations

Category: Ankle; Arthroscopy Introduction/Purpose: The purpose of the present study was to evaluate the outcomes of arthroscopic microfracture for osteochondral lesions of the talus, in patients of older than 60 years old. Methods: Sixteen patients (16 ankles) with osteochondral lesions of the talus were treated by arthroscopic microfracture from October 2012 to June 2019. As two patients were lost to follow-up, Fourteen patients (14 ankles) participated in the study. There were 6 men (42.9%) and 8 women (57.1%) of average age 67.4years (range 60-77) at the time of surgery. Clinical outcome evaluations were performed using Foot and Ankle Outcome Score (FAOS) and patient’s satisfaction after surgery at a mean follow-up of 50.8 months. Results: Mean FAOS scores improved from SYMPTOM 68.2 points (range 39-86), PAIN 65.1 points (range 36-94), ADL 69.4 points (range 32-99), SPORTS 45.4 points (range 25-80), QOL 47.1 points (range 13-94) preoperatively to SYMPTOM 94.8 points (range 68-100), PAIN 91.1 points (range 48-100), ADL 93.3 points (range 59-100), SPORTS 71.8 points (range 30-100), QOL 79.8 points (range 25-100) at final follow up. Very satisfaction in 4 (29%), Satisfaction in 7 (50%), Fair in 2 (14%), Dissatisfaction in 1 (7%), and reason for dissatisfaction was persistent pain after surgery. Conclusion: Arthroscopic microfracture for osteochondral lesions of the talus is a safe and effective procedure for old age patient.

Tendon Autograft

The aim of the study was to evaluate the results of the medial patellofemoral ligament reconstruction with a medial strip of patellar tendon autograft after a minimum 2-year followup. Ten patients (10 knees) were operated on by one surgeon, according to the modified technique, described by Camanho, without any bone plug at free graft end. The mean age of the patients was 27.2 years (ranging from 18 to 42 years). The mean follow-up period was 3 years and 7 months. All patients were reviewed prospectively. At the last follow-up visit, all the patients demonstrated a significant improvement in terms of patellofemoral joint stability, all aspects of the KOOS questionnaire, and Kujala et al.’s score (59.7 points preoperatively and 84.4 points at the last followup). No patient revealed recurrent dislocation. The SF-36 score revealed a significant improvement in bodily pain, general health, physical role functioning, social role functioning, and physical functioning domains. The described MPFL reconstruction with the use of the medial 1/3rd of patella tendon is an effective procedure that gives satisfactorily patellofemoral joint functions, improves the quality of life, and provides much pain relief. It is relatively simple, surgically not extensive, and economically cost-effective procedure.
