A chemical investigation of the aerial parts of Piper sarmentosum resulted in the isolation and identification of 14 amide alkaloids, including three new amide alkaloids, pipersarmenoids A - C (1-3), three new natural amide alkaloids, pipersarmenoids D - F (4-6), and 8 known analogues, N-p-coumaroyltyramine (7), piperlotine C (8), piperlotine D (9), pellitorine (10), sarmentine (11), aurantiamide acetate (12), 1-cinnamoyl pyrrolidine (13) and sarmentamide B (14). Their structures were determined by spectroscopic analysis including HRESIMS and 1D and 2D NMR. The cytotoxicity, neuroinflammation-inhibiting and acetylcholinesterase (AChE) inhibitory activities of those compounds were tested.

From May 2017 to November 2022, a total of 258 patients undergoing elective first-time CABG surgery, receiving 100 mg/day oral aspirin and 75 mg/day oral clopidogrel postoperatively, was included for analysis. These patients were categorized based on CYP2C19 genotyping.

The absence of specific therapeutic interventions tailored to FLD at various stages of the disease renders its treatment exceptionally arduous. Despite the fact that FLD and hyperlipidemia are intimately associated, there is still debate over how lipid-lowering medications affect FLD.

The structures and absolute configurations of these compounds were elucidated by extensive spectroscopic analyses, single-crystal X-ray diffraction, and comparison of experimental and calculated electronic circular dichroism (ECD) data. Structurally, glaucatotone A (1) is characterized as a dihomosesquiterpenoid with an unprecedented 5/5/7/6 ring system.

Recent studies have suggested that aspirin may also be effective in preventing VTE, but it is still controversial whether it can be routinely used. To compare the efficacy and safety of aspirin against oral anticoagulants in the prevention of VTE following total hip arthroplasty (THA), total knee arthroplasty (TKA) or hip fracture surgery (HFS).

The common denominator in these conditions is the potential therapeutic target of guanylate cyclase. Thanks to in-depth explorations of their underlying signaling mechanisms, the targets of these drugs are becoming clearer.

The aim of this study was to develop and validate a predictive model with radiomics analysis based on multiparametric magnetic resonance (MR) images to predict early recurrence of HCC.
Methods: In total, 302 patients (training dataset: = 211; validation dataset: = 91) with pathologically confirmed HCC who underwent preoperative MR imaging were enrolled in this study.
Background: Alpha-fetoprotein-negative (<20 ng/mL) hepatocellular carcinoma (AFP-NHCC) cannot be easily diagnosed in clinical practice, which may affect early treatment and prognosis. Furthermore, there are no reliable tools for the prediction of AFP-NHCC early recurrence that have been developed currently. The objective of this study was to identify the independent risk factors for AFP-NHCC and construct an individual prediction nomogram of early recurrence of these patients who underwent curative resection.

Primary pericardial angiosarcoma is a rare malignant cardiac neoplasm with early metastasis and poor prognosis. There are currently no guidelines or effective therapeutic strategies. Here we report a case of a 22-year-old man who presented with chest pain, suffocation and transient syncope over the course of 4 months.

As gene-editing technology has become more and more popular in the life sciences, CRISPR has brought good news to scientific researchers because of its efficiency, convenience, and wide application. Its wide application has also promoted the development of basic scientific research, agriculture, basic medicine, and clinical treatment. However, how the CRISPR/dCas9 system is effectively delivered to the target organs or cells is still unknown.

The risk of cerebral infarction (CI) is contributed to the combination of environmental influences and genetic factors. The Apolipoprotein E (APOE) gene polymorphism as a risk factor in CI has been suggested, but direct evidence from genetic association studies remains inconclusive even in Chinese population. The purpose of this study was to identify association between the APOE ε2/ε3/ε4 polymorphism and the development of CI.
