Nanoporous anodic alumina (nPAA) films formed on aluminum in lower aliphatic carboxylic acids exhibit blue self-coloring and characteristic properties such as photoluminescence (PL), electroluminescence, and electron spin resonance. The blue colors are seemingly originated from the adsorbed radicals incorporating into the oxide during the aluminum anodization. However, there is lack of reports revealing the detailed activation mechanism of the adatoms in the complexes.

The influence of the MgO/AlO ratio on various properties, including the thermal behavior, pyrometric cone refractory behavior, phase formation, physical properties, and microstructure of the synthesized ceramics, was systematically analyzed. Increasing the MgO/AlO ratio progressively weakened the cordierite network, leading to lower temperatures for liquid formation and melting.

Chronic inflammation is persistent disease caused by unregulated activation of pathway and production of pro-inflammatory cytokines, induced by accumulation of reactive oxygen species above thresholds. The purpose of this study was to evaluate the anti-oxidant, anti-lipidemia, inhibition pathway, and reduction of pro-inflammatory cytokine activities of extract (IDE) to demonstrate its inhibitory ability against chronic inflammatory in RAW264.7.

This study aims to elucidate the association between atopic dermatitis and dementia employing systematic review, meta-analysis, and Mendelian randomization (MR). A comprehensive search was performed to select eligible cohort studies using Medline, Embase, Scopus, ScienceDirect, and the Web of Science database.

However, large-scale investigations exploring the impact of changes in PD status on CVD risk are scarce. This study aimed to investigate the association between the dynamics in PD and the risk of incident CVD in a nationally representative population.

The study aims to explore the relationship between individual thigh muscle volumes and grip strength, leveraging advanced AI-based UNETR segmentation techniques for accurate muscle volume assessment.
Methods: The study included 49 participants from a cohort of 478 patients diagnosed with hip fractures at Gyeongsang National University Hospital.
Context: Fragility fractures in young adults present significant clinical challenges due to the limited evidence on the effectiveness of bisphosphonates in preventing subsequent fractures.
Objective: To evaluate the effectiveness of bisphosphonate therapy in reducing the fracture risk among premenopausal women with a history of osteoporotic fractures.
Design: A population-based retrospective cohort study was conducted using data from the National Health Insurance Service-National Sample Cohort (NHIS-NSC) in South Korea, covering the years 2003 to 2014.
This study investigates the effects of two parathyroid hormone (PTH) analogs, rhPTH(1-34) and dimeric PTH(1-34), on bone regeneration and osseointegration in a postmenopausal osteoporosis model using beagle dogs. Twelve osteoporotic female beagles were subjected to implant surgeries and assigned to one of three groups: control, rhPTH(1-34), or dimeric PTH(1-34). Bone regeneration and osseointegration were evaluated after 10 weeks using micro-computed tomographic (micro-CT), histological analyses, and serum biochemical assays.

Mechanical thrombectomy, especially with stent retrievers, offers a promising treatment, particularly for patients ineligible for intravenous tissue plasminogen activator (IV tPA) therapy. This study aimed to develop and evaluate novel stent retriever designs to enhance mechanical properties and vessel compatibility.

Background And Purpose: Rescue stent (RS) is an accepted rescue option after failed mechanical thrombectomy (MT) for acute ischemic stroke due to intracranial atherosclerotic stenosis (ICAS)-related large vessel occlusion (LVO). However, the long-term outcomes (≥ 12 months) of RS have not yet been elucidated.
Materials And Methods: We retrospectively analyzed the data of 154 patients with RS for ICAS-related LVO, which were identified from prospectively maintained multicenter database of RS after MT failure, to assess good outcome (mRS 0-2), mortality, stroke recurrence, symptomatic intracranial hemorrhage (SICH) and stent patency.
Objective: Medication-related osteonecrosis of the jaw (MRONJ) is a rare but debilitating disease characterized by a progressive necrosis of jaw bones in patients who have received anti-resorptive or anti-angiogenic therapies. Unfortunately, we still have no validated preventive or pharmaceutical interventions to help these patients, primarily due to our limited understanding of MRONJ pathogenesis. Here, we offer an extensive review of recent studies relevant to MRONJ pathogenesis.

Background: Many patients with lung cancer have underlying chronic lung diseases. We assume that baseline lung functions might also affect the prognosis of non-small cell lung cancer (NSCLC) patients receiving immunotherapy.
Objectives: We aimed to assess the impact of pretreatment clinical parameters, including lung function measures such as forced vital capacity (FVC), on the prognosis of patients with NSCLC following immune checkpoint inhibitors (ICIs) therapy.
In this study, we propose a novel rectification method for three cameras using a single image for depth estimation. Stereo rectification serves as a fundamental preprocessing step for disparity estimation in stereoscopic cameras. However, off-the-shelf depth cameras often include an additional RGB camera for creating 3D point clouds.

This study aims to examine whether the administration of PZA is associated with poor outcomes during TB treatment among elderly individuals.
Methods: A retrospective analysis was undertaken on data collected from a prospective cohort conducted between July 2019 and June 2023, which involved tuberculosis patients from 18 institutions across the Republic of Korea.
Vepdegestrant (formerly ARV-471), a novel proteolysis-targeting chimera (PROTAC), targets estrogen receptor alpha (ERα) for degradation, offering a promising option to treat advanced ER-positive breast cancer. We developed and validated a sensitive and rapid liquid chromatography-tandem mass spectrometry method to quantify vepdegestrant in rodent plasma using bavdegalutamide (formerly ARV-110) as an internal standard. Plasma samples were prepared with protein precipitation using acetonitrile and analyzed using reverse-phase C18 columns and a mobile phase of 10 mM ammonium formate in distilled water and acetonitrile.

The proposed algorithm prevents overserving APs and ensures the connectivity of all UEs, even when the number of UEs is significantly greater than the number of APs. Additionally, we assume the use of low-resolution analog-to-digital converters (ADCs) to reduce fronthaul capacity.
