Recurrent strokes after transcatheter aortic valve replacement in an elderly patient with severe bicuspid aortic valve stenosis: a case report.

Background: Transcatheter aortic valve replacement (TAVR) has evolved from a novel technology to an established therapy for high-risk patients with symptomatic severe aortic valve stenosis (AS). Recently, its use has also been extended to low-risk patients, resulting in its increasing utilization in patients with bicuspid aortic valve (BAV). But as a serious post-TAVR complication, ischemic stroke was associated with a nearly 6-fold increased 30-day mortality.

Feature-interactive Siamese graph encoder-based image analysis to predict STAS from histopathology images in lung cancer.

Spread through air spaces (STAS) is a distinct invasion pattern in lung cancer, crucial for prognosis assessment and guiding surgical decisions. Histopathology is the gold standard for STAS detection, yet traditional methods are subjective, time-consuming, and prone to misdiagnosis, limiting large-scale applications. We present VERN, an image analysis model utilizing a feature-interactive Siamese graph encoder to predict STAS from lung cancer histopathological images.

Safety and efficacy of percutaneous mechanical thrombectomy in the treatment of acute medium- or high-risk pulmonary embolism: a single-center retrospective cross-sectional study.

Background: Patients with acute and high-risk pulmonary embolism have a high mortality rate, and the optimal treatment for these patients has still not been fully established. Although anticoagulation therapy is currently the preferred treatment for pulmonary embolism, for some patients with intermediate- or high-risk pulmonary embolism, anticoagulation therapy alone has a higher probability of long-term pulmonary hypertension and also seriously worsens the quality of life of patients. This paper mainly reports the efficacy and safety of percutaneous mechanical thrombectomy (PMT) in patients with acute medium- or high-risk pulmonary embolism in Taizhou Hospital of Zhejiang Province so as to provide some clinical basis for the treatment of such patients in the future.

Unusual variants implicate uncommon genetic mechanisms for X-linked hypophosphatemic rickets.

X-linked hypophosphatemic rickets (XLH), the most common form of hereditary rickets, is characterized by renal phosphate wasting and abnormal vitamin D metabolism due to elevated circulating levels of the phosphatonin fibroblast growth factor 23 (FGF23). Dominant inactivating variants of the phosphate regulating endopeptidase homolog, X-linked (), gene are present in patients with XLH, and more than half of affected patients carry de novo variants. We report on 3 families in whom affected members had highly unusual pathogenic variants.

Immunotherapy tends to be more effective in "hot tumors" characterized by a high abundant immune cells. Our previous studies found that secretagogin (SCGN) showed intranuclear aggregation in the early stages of clear cell renal cell carcinoma (ccRCC) development.

A multi-centre metal-free COF@g-CN catalyst assembled with covalent bonds for photocatalytic CO reduction.

Photocatalytic carbon dioxide (CO) reduction technology using solar energy can convert carbon dioxide into fuels and chemicals, and is one of the most effective strategies to mitigate the energy crisis and greenhouse effect. In recent years, covalent organic frameworks (COFs) have flourished due to their unique advantages and have received extensive attention in the field of photocatalytic reduction of CO. Here, we use the pre-designability of COFs to preserve the aldehyde group at the end of the COF skeleton by the motif strategy, while ensuring its excellent photosensitivity.

Upcycled high-strength aluminum alloys from scrap through solid-phase alloying.

Although recycling secondary aluminum can lead to energy consumption reduction compared to primary aluminum manufacturing, products produced by traditional melt-based recycling processes are inherently limited in terms of alloy composition and microstructure, and thus final properties. To overcome the constraints associated with melting, we have developed a solid-phase recycling and simultaneous alloying method. This innovative process enables the alloying of 6063 aluminum scrap with copper, zinc, and magnesium to form a nanocluster-strengthened high-performance aluminum alloy with a composition and properties akin to 7075 aluminum alloy.
