Detective flow imaging (DFI) endoscopic ultrasonography (EUS) can identify the microvascular flow imaging of a mural nodule (MN) in an intraductal papillary mucinous neoplasm (IPMN) without the use of contrast agents. This retrospective study evaluated the diagnostic accuracy of DFI-EUS and its ability to evaluate the blood flow of MNs in IPMNs. Between April 2021 and September 2023, 68 patients with MNs in IPMNs observed on EUS images were retrospectively analyzed.

This study investigates the seasonal variations in the elemental composition of five economically valuable fish species from Bozcaada, North Aegean: red seabream (), gilthead seabream (), saddled seabream (), white seabream (), and common dentex (), with a focus on both essential minerals and toxic metals. Fish samples ( = 10 per species per season) were collected across four seasons, and their weights and lengths were recorded. The concentrations of elements such as calcium, potassium, magnesium, phosphorus, copper, iron, manganese, zinc, chromium, nickel, selenium, cadmium, and mercury were analyzed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS).

This paper aimed to study the nutritional, phytochemical and rheological properties of some composite flours based on wheat flour (WF) mixed with non-germinated (LF) and sprouted lentil flour (SLF), in order to fortify the wheat flour and to obtain functional bakery/pastry products. The composite flours based on wheat flour and bean lentil flour (BLWF) and sprouted lentil flour (SLWF) were analyzed from the point of view of proximate composition (proteins, lipids, total carbohydrates, and minerals), content of individual and total polyphenols (TPC), as well as the contents of macro and microelements. For use in baking/pastries, the composite flours were tested from the point of view of rheological behavior using the MIXOLAB system, and the profiles obtained were compared with those of bread and biscuit.

TNFSF9 Silence Impedes Cerebral Ischemia-Reperfusion Injury via Modulating SLC3A2 Expression in Brain Microvascular Endothelial Cells.

J Mol Neurosci

January 2025

Department of Special Examination, Affiliated Mental Health Center & Hangzhou Seventh People's Hospital, Zhejiang University School of Medicine, No. 305 Tianmushan Road, Hangzhou City, 310013, Zhejiang, China.

Cerebral ischemia-reperfusion injury (CIRI), which stays unresolved in the clinic, occurs after recanalization of blood vessels serving brain tissues in acute ischemic stroke patients and can result in massive brain cell death, and cell ferroptosis contributes greatly to this process. Our research firstly found that TNFSF9 expression harbored diagnostic value on CIRI patients and intended to further investigate its regulatory mechanism in CIRI, which might facilitate its diagnostic and therapeutic application in the clinic. The level of TNSF9 mRNA was augmented in the plasma of CIR patients, and its silence impeded ferroptosis, apoptosis, and release of inflammatory mediators of BMECs with OGD/R treatment.

School of Chemical Engineering and Technology, Key Laboratory for Green Chemical Technology of Ministry of Education, Tianjin University, Tianjin, 300072, China.

Precisely managing electron transfer pathways throughout the catalytic reaction is paramount for bolstering both the efficacy and endurance of catalysts, offering a pivotal solution to addressing concerns surrounding host structure destabilization and cycling life degradation. This paper describes the integration of B-Ni dual single-atoms within MnO channels to serve as an electronic reservoir to direct the electron transfer route during methane catalytic combustion. Comprehensive analysis discovers that B atoms weaken the interaction between O and Mn atoms by forming bonds with lattice oxygen atoms.

Revealing ionically isolated Li loss in practical rechargeable Li metal pouch cells.

Sci Bull (Beijing)

Wuhan National Laboratory for Optoelectronics, Huazhong University of Science and Technology, Wuhan 430074 China. Electronic address:

The degradation of rechargeable lithium (Li) metal batteries is primarily attributed to active Li loss, encompassing isolated Li, also known as "dead Li", and solid electrolyte interphase (SEI-Li). Comprehending the formation of dead Li is pivotal for devising strategies to mitigate Li loss. Herein, we reveal the existence of an alternative form of dead Li, termed ionically isolated Li (I-iLi), which diverges from the traditionally recognized electronically isolated Li (E-iLi).

Minnesota Department of Natural Resources, Wildlife Health Program, 5463 West Broadway, Forest Lake, MN 55025, USA.

During a survey for other parasitic infections, tongue and limb muscles of wild bobcats (Lynx rufus) were examined microscopically from a sample of 190 Minnesota bobcats. One batch (n = 50) was studied in 2015, yielding no cases of Trichinella when examined only with hematoxylin and eosin (HE) staining of <25 mg of tissue. In a 2024 cohort (n = 140), this method was paired with a compression of ∼5 g of tissue.

Key Laboratory of Medicinal Chemistry and Molecular Diagnosis of the Ministry of Education, College of Chemistry and Materials Sciences, Hebei University, Baoding 071002, Hebei, China.

Screening carbonyl reductases with the ability to catalyze the reduction of complex carbonyl compounds is of great significance for the biosynthesis of -tolvaptan(-TVP). In this study, the target carbonyl reductase in the crude enzyme extract of rabbit liver was separated, purified, and identified by ammonium sulfate precipitation, gel-filtration chromatography, ion exchange chromatography, affinity chromatography, and protein mass spectrometry. With the rabbit liver genome as the template, the gene encoding the carbonyl reductase was amplified by PCR and the recombinant strain was successfully constructed.

Melanoma is characterized by its aggressiveness, high metastatic potential, and numerous mutations, which limit the effectiveness of current treatments. To address this issue, we developed a dissolvable microneedle (MN) system composed of poly(2-ethyl-2-oxazoline) (PEtOz) and chondroitin sulfate (CS). This MN system was loaded with liposomes containing both a NIR-II photothermal small molecule (IRLy) and the natural anticancer agent Gambogic acid (GA), forming Lip(IRLy + GA) MNs.

In this Expert Opinion, we provide the rationale for concluding that radiation segmentectomy (using RADSEG method), a technique of administrating ablative, complete necrosis-inducing trans-arterial Yttrium-90 (Y90) radiotherapy in limited-disease burden hepatocellular carcinoma (HCC), is curative. Currently, curative options for early stage and other carefully selected HCC patients include transplantation, resection, and ablation. Because of issues with organ availability, co-morbidities preventing resection, and tumor size and location limiting ablation, other treatments are necessary for this selected patient population.
