Pterostilbene Exhibits Broad-Spectrum Antiviral Activity by Targeting the Enterovirus Capsid, Inactivating Viral Particles, Blocking Viral Binding, and Protecting Mice From Lethal EV-A71 Challenge.

Human enteroviruses (EVs) are a major public health issue worldwide owing to their potential to cause respiratory illnesses, hand-foot-and-mouth disease, and severe neurological complications. Currently, no effective drugs or multivalent vaccines are available. Pterostilbene (Pte), a naturally occurring compound found in blueberries and other plants, is a type of stilbene with a similar structure to resveratrol.

Accurate drone corner position estimation in complex backgrounds with boundary classification.

This study develops an efficient approach for precise channel frame detection in complex backgrounds, addressing the critical need for accurate drone navigation. Leveraging YOLACT and group regression, our method outperforms conventional techniques that rely solely on color information. We conducted extensive experiments involving channel frames placed at various angles and within intricate backgrounds, training the algorithm to effectively recognize them.

A novel mucosal bivalent vaccine of EV-A71/EV-D68 adjuvanted with polysaccharides from Ganoderma lucidum protects mice against EV-A71 and EV-D68 lethal challenge.

Background: Human enteroviruses A71 (EV-A71) and D68 (EV-D68) are the suspected causative agents of hand-foot-and-mouth disease, aseptic meningitis, encephalitis, acute flaccid myelitis, and acute flaccid paralysis in children. Until now, no cure nor mucosal vaccine existed for EV-A71 and EV-D68. Novel mucosal bivalent vaccines are highly important for preventing EV-A71 and EV-D68 infections.

Dietary citrate supplementation enhances longevity, metabolic health, and memory performance through promoting ketogenesis.

Citrate is an essential substrate for energy metabolism that plays critical roles in regulating cell growth and survival. However, the action of citrate in regulating metabolism, cognition, and aging at the organismal level remains poorly understood. Here, we report that dietary supplementation with citrate significantly reduces energy status and extends lifespan in Drosophila melanogaster.

Optimization of aptamer selection on an automated microfluidic system with cancer tissues.

Cancer is among the world's most deadly inflictions, and early diagnosis is critical. Aptamers have shown utility as cancer probes since they can be screened rapidly in vitro against cancer tissues using systematic evolution of ligands by exponential enrichment (SELEX) process. However, bench-top SELEX procedures are relatively labor-intensive and time-consuming; ideally, they could instead be carried out on microfluidic devices, yet this requires optimization of buffer and reaction conditions.

Efficacy and Safety of Olmesartan in the Treatment of Mild-to-Moderate Essential Hypertension in Chinese Patients.

Background And Objective: Hypertension is very prevalent in the Chinese population in Taiwan. Chinese people frequently experience bothersome cough when receiving angiotensin-converting enzyme (ACE) inhibitors, and angiotensin II (AT(1)) receptor antagonists are thus relatively more frequently used in this context. In this trial we studied the effectiveness of a new AT(1) receptor antagonist, olmesartan, in the treatment of Chinese patients with mild-to-moderate essential hypertension.

Acute aortic dissection developing acute myocardial infarction diagnosed by accidentary inserting the catheters into the false lumen during catheterization: a pitfall and rare image.

A case of acute aortic dissection complicating acute inferior myocardial infarction diagnosed by accidentally inserting the catheters into the false lumen during the emergency cardiac catheterization is reported. Although the incidence of acute aortic dissection developing acute myocardial infarction is not very rare, an aortogram and coronary angiogram via the false lumen has never been seen before. This case also illustrates how myocardial infarction can mask aortic dissection.

Spinal epidural hematoma following tissue plasminogen activator and heparinization for acute myocardial infarction.

The case of a 43-year-old Taiwanese man who presented with spinal epidural hematoma following intravenous administration of recombinant tissue plasminogen activator (rTPA) and heparin therapy for acute myocardial infarction (AMI) is reported. Upper back pain and progressive neurological dysfunction ensued, secondary to spinal epidural hematoma with spinal cord compression. The patient did not recover neurologic function postsurgically, possibly because the operation was delayed.

Branch retinal artery occlusion after diagnostic cardiac catheterization.

A case of right branch retinal artery occlusion (BRAO) due to cholesterol-containing embolus following transfemoral cardiac catheterization is reported. It is extremely rare, however, cardiologists should be alert to any thromboembolic complications during and following cardiac catheterization and choose the suitable approach (either upper extremity or transfemoral).
