Mechanism of influence of nattokinase terminal sequence on catalytic performance and molecular modification.

Nattokinase from traditional food natto has the potential to be a thrombolytic agent. Its terminal sequence has an important effect on the catalytic performance of nattokinase, but the specific mechanism is still unclear. In this study, computational simulation combined with truncated mutagenesis and alanine scanning technology were used to identify the key sites affecting the catalytic performance of nattokinase.

In Vivo and In Vitro Study of a Multifunctional SF/nHAp Corrosion-Resistant Bio-Coating Prepared on MAO Magnesium Alloy via Ultrasonic Spraying.

Magnesium alloys are often used in bone repair surgeries due to their biodegradability and excellent elastic modulus, making them a promising alternative to traditional nondegradable implants like titanium alloys. However, their rapid degradation rate limits their use as implants in the body. To enhance the corrosion resistance and bioactivity of magnesium alloys, we applied an ultrasonic spray coating on microarc oxidized (MAO) AZ31 magnesium alloy, using a mixture of silk fibroin (SF) and nanohydroxyapatite (nHAp).

Development of a nomogram model for predicting dementia risk in the older adult population of Weifang, Shandong Province, China: based on the biopsychosocial model.

Background: Dementia has emerged as a predominant health challenge. However, there is a notable research gap in the collective screening of dementia risks. Hence, there is a pressing need to formulate a dementia prediction tool tailored to the older adult demographic, enabling the identification of high-risk individuals for dementia.

Pancreatic lipase-inhibiting polysaccharide from Stropharia rugosoannulata: Structural characterization and interaction mechanisms.

Obesity as a global epidemic concern is often considered as a risk factor for multiple metabolic syndrome. Exploring safe and effective natural ingredients exhibiting excellent pancreatic lipase (PL) inhibition has become a promising way to overcome this issue. This study aimed to investigate the structural characterization of Stropharia rugosoannulata polysaccharide (STR-II*) as well as its inhibition effect and mechanism on PL.

Global epidemiology of acute kidney injury in hospitalised patients with decompensated cirrhosis: the International Club of Ascites GLOBAL AKI prospective, multicentre, cohort study.

Background: Acute kidney injury (AKI) is a serious complication of cirrhosis. A systematic, global characterisation of AKI occurring in patients with cirrhosis is lacking. We therefore aimed to assess global differences in the characteristics, management, and outcomes of AKI in hospitalised patients with cirrhosis.
