Correlation between ankle-brachial index and subtle cognitive decline.

Background: Subtle cognitive decline (SCD) is considered the early stage of Alzheimer's disease (AD) and is of great clinical significance for the prevention and treatment of AD. The ankle-brachial index (ABI) has been reported to be associated with cognitive impairment; however, there are few studies on the relationship between ABI and SCD.

Methods: From August 2019 to April 2021, subjects were recruited to participate in a cognitive function test at the Shanghai Sixth People's Hospital.

Crop rotations increased soil ecosystem multifunctionality by improving keystone taxa and soil properties in potatoes.

Continuous cropping of the same crop leads to soil degradation and a decline in crop production, and these impacts could be mitigated through rotation cropping. Although crop rotation enhances soil fertility, microbial community diversity, and potato yield, its effects on the soil ecosystem multifunctionality (EMF) remain unclear. In the present research, we comparatively examined the effects of potato continuous cropping (PP) and rotation cropping [potato-oat rotation (PO) and potato-forage maize rotation (PFM)] on the soil EMF as well as the roles of keystone taxa, microbes abundance, and chemical properties in EMF improvement.

Genome sequence of the potato pathogenic fungus Alternaria solani HWC-168 reveals clues for its conidiation and virulence.

Background: Alternaria solani is a known air-born deuteromycete fungus with a polycyclic life cycle and is the causal agent of early blight that causes significant yield losses of potato worldwide. However, the molecular mechanisms underlying the conidiation and pathogenicity remain largely unknown.

Results: We produced a high-quality genome assembly of A.

Development of a Semi-nested PCR-Based Method for Specific and Rapid Detection of Alternaria solani Causing Potato Early Blight in Soil.

Early blight, caused by Alternaria solani, is one of the most devastating diseases of potato that causes severe yield loss worldwide. The infected potato debris existed in the soil serve as the initial infection sources for the next growing potato. Current identification of A.

Mitochondrial DNA polymorphisms in Phytophthora infestans: new haplotypes are identified and re-defined by PCR.

Polymorphisms of mitochondrial DNA (mt-DNA) are particularly useful for monitoring specific pathogen populations like Phytophthora infestans. Basically type I and II of P. infestans mt-DNA were categorized by means of polymorphism lengths caused by an ~2 kb insertion, which can be detected via restriction enzyme digestion.

The relationship between glucose excursion and cognitive function in aged type 2 diabetes patients.

Objective: Evidence suggests that type 2 diabetes (T2DM) is associated with an increased risk of dementia and that glucose variability is an independent risk factor for diabetic complications. This study investigated the relationship between glucose excursion and cognitive function in aged T2DM patients.

Methods: A total of 248 aged T2DM patients wore a continuous glucose monitoring system (CGMS) for 3 days in order to evaluate glucose excursion, including mean amplitude of glycemic excursions (MAGE) and mean of daily difference (MODD).
