Objective: Various nail disorders have been reported in patients with chronic kidney disease. However, few studies have investigated nail disorders in patients with advanced chronic kidney disease. This study focused on nail disorders seen in patients with end-stage renal disease (ESRD) undergoing conservative treatment. methods: A case-control study was conducted at Baraha medical City in Khartoum State, Sudan. Data on patients with ESRD who were on conservative treatment and presented for follow-up between march and September 2021 were collected. Patients' demographic features, nail findings on clinical examination, and laboratory results were recorded. The obtained data were compared with those on age- and sex-matched healthy individuals from the general population. The chi-square test and Student t test were performed to analyze categorical and numerical variables, respectively. Results: Data on 78 patients with ESRD were studied. Their mean age was 54.6 ± 17.6 years, and 45 (57.7%) were men. These patients were compared with 129 controls. Nail disorders were seen in 65 (83.3%) ESRD patients and 86 (66.6%) controls (P = 0.009). Patients with ESRD were found to be at increased relative risk of developing a wide spectrum of nail disorders. An absent lunula, half-and-half nails, nail dystrophy, Terry's nails, onychomycosis, and koilonychia were the most common disorders and were seen in 44 (56.4%), 13 (16.7%), 10 (12.8%), 9 (11.5%), 6 (7.7%), and 5 (6.4%) patients, respectively. Patients with ESRD had a statistically significant risk of developing above diseases (all P monstrated a wide spectrum of nail disorders in patients with ESRD undergoing conservative treatment. Further studies are essential to understand their pathogenesis. © 2024 Hospital for Skin Diseases (Institute of Dermatology), Chinese Academy of medical Sciences, and Chinese medical Association, published by Wolters Kluwer, Inc.

A FLEXIBLE OBJECTIVE-CONSTRAINT APPROACH AND A NEW ALGORITHm FOR CONSTRUCTING THE PARETO FRONT OF mULTIOBJECTIVE OPTImIZATION PROBLEmS

引用

Acta mathematica Scientia 2024年第2期44卷 702-720页

作者： N.HOSEINPOOR m.GHAZNAVI Faculty of mathematical Sciences Shahrood University of TechnologyShahroodIran

In this article, a novel scalarization technique, called the improved objective-constraint approach, is introduced to find efficient solutions of a given multiobjective programming problem. The presented scalarized problem extends the objective-constraint problem. It is demonstrated that how adding variables to the scalarized problem, can lead to find conditions for (weakly, properly) Pareto optimal solutions. Applying the obtained necessary and sufficient conditions, two algorithms for generating the Pareto front approximation of bi-objective and three-objective programming problems are designed. These algorithms are easy to implement and can achieve an even approximation of (weakly, properly) Pareto optimal solutions. These algorithms can be generalized for optimization problems with more than three criterion functions, too. The effectiveness and capability of the algorithms are demonstrated in test problems.

Embracing substrate multispecificity in plant ABC transporters

molecular Plant 2024年第7期17卷 990-992页

作者： markus m.Geisler Department of Biology University of Fribourg1700 FribourgSwitzerland

By analogy,the first plant ATP-binding cassette(ABC)transporters were identified as vacuolar detoxifiers transporting glutathione conjugates into the vacuole(martinoia et al.,1993).This somewhat negative image as"unspecific detoxifiers"still clings to plant ABC transporters today,although they have since been described to be involved in completely different programs,including development and defense(Park et al.,2017).In this context,some key plant ABC transporters have been shown to own exceptionally high substrate *** example,the transporter of the native auxin indole-3-acetic acid(IAA),Arabidopsis ABCB1,has been shown to also export the synthetic auxin 1-naphtaleneacetic acid but is even able to distinguish this substrate from its structural isomer,2-naphtaleneacetic acid(Geisler et al.,2005).Likewise,ABCG36 and ABCG37,which are known to have a broader substrate portfolio(Park et al.,2017;Aryal et al.,2023),export IBA but do not touch IAA(Aryal et al.,2023).Recently,several reports have challenged our current view on the reported high substrate specificity of plant ABCs,which requires clarification.
