Vapor-phase tert-butylation of p-hydroxytoluene over Al-MCM-41 and PWA supported Al-MCM-41 mesoporous molecular sieve catalysts

open access: yesCatalysis Communications, 2007
Abstract Mesoporous Al-MCM-41 and PWA, impregnated with different weight percent catalysts have been prepared and investigated by combining structural and textural properties of both the catalysts. The catalytic behavior of both the Al-MCM-41 and PWA impregnated catalysts were evaluated for tert-butylation of p -hydroxy toluene.

Super‐Refractory Status Epilepticus (SRSE) in a Patient With Compound Heterozygous OPA1 Variants: Case Report and Literature Review

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.

Mycophenolate Mofetil Treatment Reduces the Risk of Treatment Escalation Due to Vascular Complications in Limited Cutaneous Systemic Sclerosis: Emulation of a Target Trial From the Italian Rheumatology Society SPRING Registry

open access: yesArthritis Care &Research, EarlyView.
Objective Mycophenolate mofetil (MMF) use in limited cutaneous systemic sclerosis (lcSSc) is relatively uncommon because of the lower fibrotic burden and the predominance of vascular complications. In vitro observations and clinical data from transplanted patients suggest a protective effect of MMF on endothelial function.

GAN‐LSTM‐3D: An efficient method for lung tumour 3D reconstruction enhanced by attention‐based LSTM

open access: yesCAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Three‐dimensional (3D) image reconstruction of tumours can visualise their structures with precision and high resolution. In this article, GAN‐LSTM‐3D method is proposed for 3D reconstruction of lung cancer tumours from 2D CT images. Our method consists of three phases: lung segmentation, tumour segmentation, and tumour 3D reconstruction. Lung

Mucocutaneous disease activity and damage accrual in systemic lupus erythematosus: analyses from the Asia‐Pacific Lupus Collaboration longitudinal cohort study

open access: yesArthritis Care &Research, Accepted Article.
Objective This research article aims to describe the prevalence, associations and health‐related quality‐of‐life (HRQoL) impact of mucocutaneous features of SLE. Methods Data from the Asia‐Pacific Lupus Collaboration cohort were analysed (2013‐2021). Mucocutaneous activity (MC‐A) items were rash, alopecia and mucosal ulcers; defined by the SLEDAI‐2K ...
