Dual leucine zipper kinase (MAP3K12) modulators: a patent review (2010–2015)

Introduction: The dual leucine zipper kinase (DLK, MAP3K12) is essential for neuronal development and has been shown to mediate axon regeneration. On the other hand, DLK is involved in the pathogenesis of neurodegenerative disease and diabetes mellitus. Several patents have been published claiming to modulate or inhibit DLK by various approaches including ATP competitive inhibitors. In addition, two publications describe SAR of highly selective DLK inhibitors with efficacy in distinct mouse models of neurodegeneration.

Areas covered: This review summarized patents claiming to modulate DLK activity published between 2010 and 2015. Peer-reviewed publications related to the patents and additional peer-reviewed publications are included. This article describes 18 patents from three pharmaceutical companies and three academic research groups.

Expert opinion: Several methods are proposed to modulate DLK activity, some of them very experimental and not suitable for easy application in patients. ATP competitive kinase inhibitors exert high affinity, but for the majority, no information about their selectivity is available. To date, two inhibitors have been tested in mice. Given the controversial findings that DLK is required for neurodegeneration and for axon regeneration, more research is needed to further elucidate the regulation and the function of this kinase in diverse organs/tissues and under physiological and pathological conditions.

Utilization of Construction and Demolition Mix Waste in the Fired Brick Production: The Impact on Mechanical Properties

The European Green Deal, which emphasizes zero-waste economies, and waste recycling in construction and building materials, has arisen due to significant worldwide needs for solid waste recovery and usage. This ambitious study focuses on recycling mixed construction and demolition (C&D) waste into burnt bricks and investigating the influence of firing temperature. While pursuing its objectives, this is dependent on raw material characterization and burnt-brick product quality assessment. The recycling of mixed C&D waste is explored by mixing the waste into two soil types (alluvial and laterite) in ratios ranging from 5% to 45% at three firing temperatures (700 °C, 850 °C and 900 °C). The utilization of mixed C&D waste in amounts of 10% at 700 °C and 25% at 850 °C and 900 °C fulfilled the Indian standard. Although a fire at 700 °C results in less optimal waste utilization, it is beneficial and recommended for reducing the carbon footprint and energy use. Additional mineralogical and microstructural analyzes are performed on the optimal fired samples. The study’s findings are promising for sustainable resource usage, reducing carbon footprint, and reducing waste disposal volume. This research is a big step toward the Sustainable Development Goals of the United Nations and a circular economy.     

dPQL: a lossless distributed algorithm for generalized linear mixed model with application to privacy-preserving hospital profiling

ObjectiveTo develop a lossless distributed algorithm for generalized linear mixed model (GLMM) with application to privacy-preserving hospital profiling.Materials and MethodsThe GLMM is often fitted to implement hospital profiling, using clinical or administrative claims data. Due to individual patient data (IPD) privacy regulations and the computational complexity of GLMM, a distributed algorithm for hospital profiling is needed. We develop a novel distributed penalized quasi-likelihood (dPQL) algorithm to fit GLMM when only aggregated data, rather than IPD, can be shared across hospitals. We also show that the standardized mortality rates, which are often reported as the results of hospital profiling, can also be calculated distributively without sharing IPD. We demonstrate the applicability of the proposed dPQL algorithm by ranking 929 hospitals for coronavirus disease 2019 (COVID-19) mortality or referral to hospice that have been previously studied.ResultsThe proposed dPQL algorithm is mathematically proven to be lossless, that is, it obtains identical results as if IPD were pooled from all hospitals. In the example of hospital profiling regarding COVID-19 mortality, the dPQL algorithm reached convergence with only 5 iterations, and the estimation of fixed effects, random effects, and mortality rates were identical to that of the PQL from pooled data.ConclusionThe dPQL algorithm is lossless, privacy-preserving and fast-converging for fitting GLMM. It provides an extremely suitable and convenient distributed approach for hospital profiling.
