Emerging two dimensional MXene for corrosion protection in new energy systems: Design and mechanisms.

With the development of new and clean energy (offshore wind power, fuel cells, aqueous zinc ion batteries, lithium-ion batteries, etc.), the corrosion and security problems in special environments of the new energy system have attracted much attention. Corrosion protection on the metals applied in new energy system can reduce the economic loss, security risk, and energy consumption, as well as guarantee the efficiency of energy system.

Toward self-healing two dimensional MXene coatings for corrosion protection on metals: Design strategies and mechanisms.

Metallic corrosion leads to high economic losses and security risks, and coating protection is an effective approach to preventing metal from corrosion. However, defects such as cracks and micropores are inevitable in the coating, so it is urgent to develop self-healing coatings for realizing long-term corrosion protection due to the actively protective ability. Though two-dimensional (2D) transition metal carbide or nitride (MXene) coatings have been employed to realize self-healing function, the design strategies of the MXene-based coatings and mechanism on how MXenes inhibit corrosion at the coating-metal interface as well as the roles of MXene in self-healing process remain elusive.

Lower synaptic density and its association with cognitive dysfunction in patients with obsessive-compulsive disorder.

Background: Understanding synaptic alteration in obsessive-compulsive disorder (OCD) is crucial for elucidating its pathological mechanisms, but research on this topic remains limited.

Aims: This study aimed to identify the synaptic density indicators in OCD and explore the relationship between cognitive dysfunction and synaptic density changes in OCD.

Methods: This study enrolled 28 drug-naive adults with OCD aged 18-40 years and 16 healthy controls (HCs).

Lipase-catalyzed interesterification of Sunite sheep tail fat and flaxseed oil provides a fat having a unique fatty acid content and favorable physicochemical and nutritional properties.

The aim of this study is to combine flaxseed oil (FO), rich in α-linolenic acid (ALA), with Sunite sheep tail fat (STF) through a lipase-catalyzed transesterification reaction, in order to produce an edible oil with a fatty acid ratio suitable for human needs. Initially, the optimal conditions for esterification were determined using the Box-Behnken design, with the measurement criterion being the content of ALA at the sn-2 position. The results indicated that the highest content of sn-2 ALA was obtained under the conditions of using 6.

Lower synaptic density associated with gaming disorder: an F-SynVesT-1 PET imaging study.

Background: Internet gaming disorder (IGD) is an ideal model to study the mechanisms underlying synaptic deficits in addiction as it eliminates the confounding effects of substance use. Synaptic loss and deficits are hypothesised to underlie the enduring maladaptive behaviours and impaired cognitive function that contribute to IGD.

Aims: This study aimed to determine whether subjects with IGD have lower synaptic density than control subjects and the relationship between synaptic density and IGD severity.

Deep Eutectic Solvents-Based Ultrasound-Assisted Extraction of Antioxidants from Kudingcha ( C.J. Tseng): Process Optimization and Comparison with Other Methods.

Kudingcha (KDC) is an important tea substitute containing abundant antioxidants. Herein, a ultrasonic-assisted extraction (UAE) technique based on deep eutectic solvents (DESs) was applied to optimize the total phenolic/total flavonoid content (TPC/TFC) from the KDC extracts. Results indicated that DES composed of L-proline and glycerol (Pro-Gly) had excellent extraction performance for TPC, TFC, ABTS and FRAP, which were significantly better than other solvents.

A meta-analysis was conducted to investigate the value of the volume parameters based on somatostatin receptor (SSTR)-positron emission tomography (PET) in predicting the prognosis in patients with neuroendocrine tumors (NETs). PUBMED, EMBASE, Cochrane library, and Web of Knowledge were searched from January 1990 to May 2021 for studies evaluating prognostic value of volume-based parameters of SSTR PET/CT in NETs. The terms used were "volume," "positron emission tomography," "neuroendocrine tumors," and "somatostatin receptor.

Biodistribution of F-AlF-NOTA-octreotide in Different Organs and Characterization of Uptake in Neuroendocrine Neoplasms.

Purpose: The aims of this study were threefold: [1] to describe the biodistribution of F-AlF-NOTA-octreotide (F-OC) in normal organs; [2] to evaluate the range of uptake of NEN and benign lesions using the maximum standardized uptake value (SUV); and [3] to compare the difference in F-OC uptake among tumors of different grades.

Methods: This study included 162 patients (67 females and 95 males) who received F-OC positron emission tomography (PET)/computed tomography (CT), 128 of whom were diagnosed with neuroendocrine neoplasms (NENs). The SUV and SUV of F-OC were measured in 21 normal anatomical structures.

Pre-Operative Prediction of Mediastinal Node Metastasis Using Radiomics Model Based on F-FDG PET/CT of the Primary Tumor in Non-Small Cell Lung Cancer Patients.

We investigated whether a fluorine-18-fluorodeoxy glucose positron emission tomography/computed tomography (F-FDG PET/CT)-based radiomics model (RM) could predict the pathological mediastinal lymph node staging (pN staging) in patients with non-small cell lung cancer (NSCLC) undergoing surgery. A total of 716 patients with a clinicopathological diagnosis of NSCLC were included in this retrospective study. The prediction model was developed in a training cohort that consisted of 501 patients.

Preoperative prediction of microvascular invasion of hepatocellular carcinoma with IVIM diffusion-weighted MR imaging and Gd-EOB-DTPA-enhanced MR imaging.

Microvascular invasion (MVI) is regarded as one of the independent risk factors for recurrence and poor prognosis of hepatocellular carcinoma (HCC). The presence of MVI in HCCs was evaluated on the basis of pathological reports of surgical specimens and was defined as tumor within a vascular space lined by endothelium that was visible only on microscopy. The aim of the study was to investigate the usefulness of intravoxel incoherent motion (IVIM) diffusion weighted (DW) magnetic resonance (MR) imaging in predicting MVI of HCC.

Angiomyolipoma of the Adrenal Gland: A Report of Two Cases and Review of the Literature.

BACKGROUND Angiomyolipoma is a benign tumor composed of blood vessels, smooth muscle cells, and adipose tissue and has been described as belonging to the group of tumors of perivascular epithelioid cell origin (PEComa), commonly found in the kidneys and strongly associated with tuberous sclerosis. Only a few cases of extra-renal angiomyolipoma have previously been reported in the literature, most commonly in the liver. Adrenal angiomyolipoma is very rare, is usually asymptomatic, and is often found incidentally, with only 14 previously reported cases identified in the literature.
