Background: The wound healing effects of a specialized amino acid supplement containing calcium beta-hydroxy-beta-methylbutyrate, L-arginine, and L-glutamine (HMB/Arg/Gln) have been reported. This study aimed to investigate the effectiveness of HMB/Arg/Gln in the perioperative management of patients with thoracic esophageal cancer.
Methods: This retrospective cohort study included 131 patients who underwent esophagectomy for thoracic esophageal cancer between January 2016 and November 2023.
Purpose: In this retrospective study, we aimed to evaluate the efficacy and incidence of radiation-induced brain necrosis (RBN) after volumetric modulated arc therapy-based stereotactic irradiation (VMAT-STI) for brain metastases.
Methods: In the 220 brain metastatic lesions included between January 2020 and June 2022, there were 1-9 concurrently treated lesions (median 1). A biologically effective dose (BED)10 of 80 Gy and a reduced BED10 of 50 Gy were prescribed to the gross tumor volume (GTV) and planning target volume (PTV) (PTV = GTV + 3 mm) margins, respectively.
Background: Past studies have reported that vertebrobasilar dolichoectasia (VBD) patients may develop similar arteriopathies other than the vertebrobasilar system. However, the details of these VBD-related arteriopathies are still unclear.
Methods: We retrospectively enrolled patients diagnosed with VBD at two stroke centers in Japan between January 2012 and December 2023.
Vascular interactions play a crucial role in embryogenesis, including skeletal development. During endochondral ossification, vascular networks are formed as mesenchymal cells condense and later invade skeletal elements to form the bone marrow. We and other groups developed a model of endochondral ossification by implanting human embryonic stem cell (hESC)-derived sclerotome into immunodeficient mice.

This case report discusses the use of an automated contouring function on CBCT images acquired during IGRT to quantify the dose distribution variations associated with tumor shrinkage in a patient with large NSCLC. A 72-year-old woman with locally advanced squamous cell carcinoma of the lung (T4N1M0; tumor diameter: 14 cm) underwent chemoradiotherapy.

Mildly elevated total serum bilirubin (TSB) levels can exert anti-atherosclerotic effects and may regulate inflammation. We explore the relationship between TSB levels, smoking, and inflammation.

In this study, we identified that a component of the septation initiation network complex, SepL, a putative protein kinase, was involved in the expression of carbohydrate-active enzyme (CAZyme) encoding genes. The deletion of sepL (ΔsepL) in A.

Conventionally acquired magnetic resonance imaging (MRI) is limited by insufficient signal intensity within bone tissue. Osseus conspicuity may be enhanced by applying sequences with "CT-like" bone contrast zero-echo time (ZTE) MRI.

Its usefulness to predict complications after 1-level or 2-level anterior cervical decompression and fusion (ACDF) has not been studied extensively.
Purpose: We aimed to assess the usefulness of the mFI-5 in 1-level or 2-level ACDF surgery by asking the following questions: (1) Is the mFI-5 a reliable tool to predict complications after 1-level or 2-level ACDF? (2) Is the mFI-5 useful in predicting prolonged hospital stay after 1-level or 2-level ACDF? (3) Is the mFI-5 useful in predicting readmission after 1-level or 2-level ACDF?
Methods: We performed a retrospective analysis of the medical records of patients who underwent 1-level or 2-level ACDF at our institution.
The ,-acetal derived from diethyl mesoxalate (DEMO) undergoes elimination of acetic acid upon treatment with a base, leading to the formation of -acylimine in situ. Lithium acetylide readily attacks the imino group to afford ,1,1-tricarbonylated propargylamines. When the resulting propargylamine reacts with butyllithium, ring closure occurs between the ethynyl and carbamoyl groups, yielding 2,5-disubstituted oxazole-4-carboxylates.

It is more likely to occur in older patients and those with obesity. However, no studies have focused on the association between LSE and local alignment.

Objectives: Postoperative axial pain (AP) is a well-known complication of cervical posterior surgery. It can be caused by various reasons, but the etiology remains unclear.
We have developed a method for the site-selective hydrogenation of unactivated alkenes using 8-aminoquinoline amide as the directing group. For unactivated alkenes with two C-C double bonds, Daugulis's 8-aminoquinoline amide facilitated the site-selective hydrogenation of the desired C-C double bond, producing a product in which one C-C double bond was reduced. Site-selective reduction methodologies using intramolecular directing groups are expected to contribute significantly to the synthesis of molecules with multiple reducible functional groups in the future.

Samples shielded from oxygen and plasma-annealed for purity exhibit narrow blue photoluminescence (PL) with quantum yields (QYs) over 60% in exceptional cases, while unshielded nanocrystals (NCs) exhibit broad blue/green/white PL with 10-15% QY. The latter scenario is attributed to excess surface carbon and oxygen accrued during synthesis and processing, with size separation through ultracentrifugation revealing size-dependent impurity emission.

We report chemoselective hydrogenation of α,β-unsaturated anilides catalyzed by the palladium-polymethylhydrosiloxane (hydrosilane) system. Under this condition, C-C double bonds are selectively reduced while other reducible groups such as acetyl groups, nitro groups, nitriles, benzyl ethers, and halogens are largely tolerated. This chemoselective hydrogenation is promising for the development of efficient synthetic routes for multi-functional compounds.

Loading of organic dyes onto the liquid crystalline clay nanosheets will enable novel photonic materials, where photofunctions of the loaded dye are controlled by the liquid crystallinity of the clay nanosheets. However, adsorption of organic dyes onto the nanosheets renders the nanosheet surfaces hydrophobic, and consequently, colloidal stability of the nanosheets is lost.

Tumor-derived extracellular vesicles (EVs) show great potential as biomarkers for several diseases, including pancreatic cancer, due to their roles in cancer development and progression. However, the challenge of utilizing EVs as biomarkers lies in their inherent heterogeneity in terms of size and concentration, making accurate quantification difficult, which is highly dependent on the isolation and quantification methods used. In our study, we compared three EV isolation techniques and two EV quantification methods.
