Approaches to the selection of cold chain logistics enterprises under hesitant fuzzy environment based on decision distance measures

Hesitant fuzzy sets are very useful in dealing with decision making problems for imprecise information. Taking account that there exist differences among the decision information given by decision makers and the hesitant fuzzy information given is in different accurate levels, we propose the concept of accuracy weight vector based on the decision distance measures for hesitant...

Fine mapping of a male sterility gene ms-3 in a novel cucumber (Cucumis sativus L.) mutant

Key message The cucumber male sterility gene ms - 3 was fine mapped in a 76 kb region harboring an MMD1 -like gene Csa3M006660 that may be responsible for the male sterile in cucumber. Abstract A cucumber (Cucumis sativus L.) male sterile mutant (ms-3) in an advanced-generation inbred line was identified, and genetic analysis revealed that the male sterility trait was controlled...

PIM1-minicircle as a therapeutic treatment for myocardial infarction

PIM1, a pro-survival gene encoding a serine/ threonine kinase, influences cell proliferation and survival. Modification of cardiac progenitor cells (CPCs) or cardiomyocytes with PIM1 using a lentivirus-based delivery method showed long-term improved cardiac function after myocardial infarction (MI). However, lentivirus based delivery methods have stringent FDA regulation with...

Health reform and out-of-pocket payments: lessons from China

Objective China’s ongoing new health reform aims to reduce individual out-of-pocket (OOP) payments for healthcare services. The aim of this article is to analyse the impact of this reform and to draw policy implications. Methods Data are retrieved from the relevant government publications. Polynomial regression models are used to predict future health expenditures. An extensive...

A Nomogram to Predict Adequate Lymph Node Recovery before Resection of Colorectal Cancer

Increased lymph node count (LNC) has been associated with prolonged survival in colorectal cancer (CRC), but the underlying mechanisms are still poorly understood. The study aims to identify new predictors and develop a preoperative nomogram for predicting the probability of adequate LNC (≥ 12). 501 eligible patients were retrospectively selected to identify clinical-pathological...

Prevalence of Depression among Chinese University Students: A Meta-Analysis

Background Depression is a major mental health issue worldwide, and university students with heavy burdens of study are at a high risk for depression. While a number of studies have been conducted regarding depression among university students in China, there is a lack of information regarding the national prevalence of depression among Chinese university students. Therefore, we...

Predictive modeling in pediatric traumatic brain injury using machine learning

Background Pediatric traumatic brain injury (TBI) constitutes a significant burden and diagnostic challenge in the emergency department (ED). While large North American research networks have derived clinical prediction rules for the head injured child, these may not be generalizable to practices in countries with traditionally low rates of computed tomography (CT). We aim to...

Impatiens pandurata (Balsaminaceae), a new species from Yunnan, China

Background The species-rich genus Impatiens is mainly distributed throughout much of tropical Africa, India, southwest Asia, southern China and Japan. There are more than 270 species recorded in China, most of which are restricted to the southwest. An unknown species of Impatiens was collected from Yunnan, southwest China. Results Impatiens pandurata Y. H. Tan & S. X. Yu, a new...

The “Gate Keeper” Role of Trp222 Determines the Enantiopreference of Diketoreductase toward 2-Chloro-1-Phenylethanone

Trp222 of diketoreductase (DKR), an enzyme responsible for reducing a variety of ketones to chiral alcohols, is located at the hydrophobic dimeric interface of the C-terminus. Single substitutions at DKR Trp222 with either canonical (Val, Leu, Met, Phe and Tyr) or unnatural amino acids (UAAs) (4-cyano-L-phenylalanine, 4-methoxy-L-phenylalanine, 4-phenyl-L-phenyalanine, O-tert...
