D-dimer-albumin ratio (DAR) as a new biomarker for predicting preoperative deep vein thrombosis after geriatric hip fracture patients.

Purpose: Hip fractures in the elderly are complicated by preoperative deep vein thrombosis (DVT). The objective of this study is to determine the usefulness of blood-based biomarkers, particularly the D-dimer-albumin ratio (DAR), in predicting preoperative DVT.

Methods: A retrospective observational study was carried out on 1149 patients from a single hospital, and subsequently validated on an additional 626 patients from a separate hospital.

Leaf spot of Alnus cremastogyne Caused by Colletotrichum gloeosporioides in Sichuan, China.

Alnus cremastogyne Burk, a broad-leaved tree endemic to south-western China, has both ecological and economic value. The tree is widely used in furniture, timber, windbreaks and sand fixation, and soil and water conservation (Tariq et al. 2018).

First report of Leaf spot Caused by Colletotrichum siamense on Pharbitis purpurea in Sichuan, China.

The Pharbitis purpurea (L.) Voisgt, a member of the Convolvulaceae, is a graceful plant with an air purifying function and ornamental values. It is often cultivated in parks and roadsides.

An Integrated Approach Fusing CEEMD Energy Entropy and Sparrow Search Algorithm-Based PNN for Fault Diagnosis of Rolling Bearings.

This paper solves the problem of difficulty in achieving satisfactory results with traditional methods of bearing fault diagnosis, which can effectively extract the fault information and improve the fault diagnosis accuracy. This paper proposes a novel artificial intelligence fault diagnosis method by integrating complementary ensemble empirical mode decomposition (CEEMD), energy entropy (EE), and probabilistic neural network (PNN) optimized by a sparrow search algorithm (SSA). The vibration signal of rolling bear was firstly decomposed by CEEMD into a set of intrinsic mode functions (IMFs) at different time scales.

The minimally invasive spinal surgery in the treatment of posterior edge separation.

Background: Posterior edge separation of the vertebral body is an uncommon but non-rare orthopedic disease, the traditional treatment is posterior open surgery. Recently, a lot of attempts in minimally invasive treatment of lumbar posterior edge fracture have been made. We set to discover the value of minimally invasive surgery in the treatment of posterior edge separation, we designed this retrospective study.

Discovery of 3,6-diaryl-1H-pyrazolo[3,4-b]pyridines as potent anaplastic lymphoma kinase (ALK) inhibitors.

A new series of 3,6-diaryl-1H-pyrazolo[3,4-b]pyridine compounds have been discovered as potent anaplastic lymphoma kinase (ALK) inhibitors. The 4-hydroxyphenyl in the 6-position of 1H-pyrazolo[3,4-b]pyridine were crucial and a fluorine atom substitution could give promising inhibitory activity. The IC of compound 9v against ALK was up to 1.

Metal-free α-alkylation of alcohols with para-quinone methides.

A metal-free α-alkylation of alcohols with para-quinone methides (p-QMs) for accessing alcohol-containing phenols and dihydroisocoumarins has been developed. The alcohols were converted to α-oxy radicals in the presence of di-tert-butyl peroxide (DTBP), which were added to p-QMs for aromatization and C(sp3)-C(sp3) bond formation.
