Background: At present, there is a dearth of objective methodologies for assessing the effectiveness of treatments for Lateral Epicondylitis (LE). This study examined 73 patients suffering from tennis elbow using a multimodal ultrasound approach and investigated the correlation between pertinent indicators and clinical scores.

Methods: 73 patients diagnosed with unilateral tennis elbow by interventional ultrasound at Zhejiang Rongjun Hospital were included in the study.

Molecular switch of the dendrite-to-spine transport of TDP-43/FMRP-bound neuronal mRNAs and its impairment in ASD.

Background: Regulation of messenger RNA (mRNA) transport and translation in neurons is essential for dendritic plasticity and learning/memory development. The trafficking of mRNAs along the hippocampal neuron dendrites remains translationally silent until they are selectively transported into the spines upon glutamate-induced receptor activation. However, the molecular mechanism(s) behind the spine entry of dendritic mRNAs under metabotropic glutamate receptor (mGluR)-mediated neuroactivation and long-term depression (LTD) as well as the fate of these mRNAs inside the spines are still elusive.

Hematuria in the ER patient: optimizing detection of upper tract urothelial cancer - A pictorial essay.

Upper tract urothelial carcinoma (UTUC) is a rare and challenging subset of the more frequently encountered urothelial carcinomas (UCs), comprising roughly 5-7% of all UCs and less than 10% of all renal tumors. Hematuria is a common presenting symptom in the emergency setting, often prompting imaging to rule out serious etiologies, with UTUC especially posing as a diagnostic challenge. These UTUC lesions of the kidney and ureter are often small, mimicking other pathologies, and are more aggressive than typical UC of the bladder, emphasizing the importance of timely and accurate diagnosis.

Unveiling the Dual Active Sites of Ni/Co(OH)-Ru Heterointerface for Robust Electrocatalytic Alkaline Seawater Splitting.

Constructing bifunctional electrocatalysts through the synergistic effect of diverse metal sites is crucial for achieving high-efficiency and steady overall water splitting. Herein, a "dual-HER/OER-sites-in-one" strategy is proposed to regulate dominant active sites, wherein Ni/Co(OH)-Ru heterogeneous catalysts formed on nickel foam (NF) demonstrate remarkable catalytic activity for oxygen evolution reaction (OER) as well as hydrogen evolution reaction (HER). Meanwhile, the potentials@10 mA cm of Ni/Co(OH)-Ru@NF for overall alkaline water and seawater splitting are only 1.

A 3D four-fold interpenetrated conductive metal-organic framework for fast and robust sodium-ion storage.

Two-dimensional conductive metal-organic frameworks (2D c-MOFs) with high electrical conductivity and tunable structures hold significant promise for applications in metal-ion batteries. However, the construction of 3D interpenetrated c-MOFs for applications in metal-ion batteries is rarely reported.

Enhancing both strength and plasticity simultaneously in nanostructured materials remains a significant challenge. While grain refinement is effective in increasing strength, it typically leads to reduced plasticity due to localized strain. In this study, we propose a novel design strategy featuring a dual-nano composite structure with grain boundary segregation to enhance the deformation stability of nanostructured materials.

Main-Group Sn Single Atoms on MoS for Selective Nitrite Electroreduction to Ammonia.

Electrocatalytic NO-to-NH reduction (NORR) offers an attractive way to remedy polluted NO and produce value-added NH. In this study, main-group Sn single atoms anchored on S-vacancy-rich MoS (Sn/MoS) are explored as a highly selective NORR catalyst. Combined theoretical computations and in situ spectroscopic measurements reveal that the isolated Sn sites of Sn/MoS can not only promote NO-to-NH activation and hydrogenation but also favor NH desorption and restrict H adsorption, thus enabling a highly selective NORR for NH synthesis.

Euglycemic diabetic ketoacidosis associated metabolic encephalopathy caused by dapagliflozin: a rare case report.

Background: Sodium-glucose cotransporter-2(SGLT-2) inhibitors are a newer class of antidiabetic drugs with the increased risk of euglycemic diabetic ketoacidosis(EuDKA). Encephalopathy is a rare but life-threatening event of EuDKA. Due to paradoxically normal or slightly elevated serum glucose levels, it's easy to be mimicked by cerebral infarction, structural brain damage, thus leading to delayed diagnosis and causing seriously irreversible brain injury.

Excess Weight Loss at 6 Months Following Laparoscopic Sleeve Gastrectomy Correlates with the Remission of Hyperuricemia.

Background: Hyperuricemia is a metabolic disorder associated with obesity. Many studies have reported the effect of bariatric surgery on the decrease of serum uric acid level in patients with hyperuricemia. However, since the update of diagnostic criteria of hyperuricemia, the correlation between preoperative body mass index, postoperative weight changes, and the remission of hyperuricemia in patients with obesity after sleeve gastrectomy requires consensus.

Motor cortical neuronal hyperexcitability associated with α-synuclein aggregation.

ΑBSTRACT: In Parkinson's disease (PD), Lewy pathology deposits in the cerebral cortex, but how the pathology disrupts cortical circuit integrity and function remains poorly understood. To begin to address this question, we injected α-synuclein (αSyn) preformed fibrils (PFFs) into the dorsolateral striatum of mice to seed αSyn pathology in the cortical cortex and induce degeneration of midbrain dopaminergic neurons. We reported that αSyn aggregates accumulate in the motor cortex in a layer- and cell-subtype-specific pattern.

Cortical arealization of interneurons defines shared and distinct molecular programs in developing human and macaque brains.

Cortical interneurons generated from ganglionic eminence via a long-distance journey of tangential migration display evident cellular and molecular differences across brain regions, which seeds the heterogeneous cortical circuitry in primates. However, whether such regional specifications in interneurons are intrinsically encoded or gained through interactions with the local milieu remains elusive. Here, we recruit 685,692 interneurons from cerebral cortex and subcortex including ganglionic eminence within the developing human and macaque species.

Nevertheless, the risk factors contributing to the development of negative emotions in thyroid nodule patients remain unidentified. This cross-sectional study recruited 150 patients diagnosed with thyroid nodules through ultrasound examination from January 2022 to January 2023 at Jinan Central Hospital, the Second Affiliated Hospital of Shandong First Medical University, and Qingyun County Maternal and Child Health Hospital as the case group, which were categorized based on their levels of anxiety and depression.

Context-Dependent Heterotypic Assemblies of Intrinsically Disordered Peptides.

Despite their critical role in context-dependent interactions for protein functions, intrinsically disordered regions (IDRs) are often overlooked for designing peptide assemblies. Here, we exploit IDRs to enable context-dependent heterotypic assemblies of intrinsically disordered peptides, where "context-dependent" refers to assembly behavior driven by interactions with other molecules. By attaching an aromatic segment to oppositely charged intrinsically disordered peptides, we achieve a nanofiber formation.
