Capacitance enhancement by ion-laminated borophene-like layered materials.

Atomically flat two-dimensional networks of boron are attracting attention as post-graphene materials. An introduction of cations between the boron atomic layers can exhibit unique electronic functions that are not achieved by neutral graphene or its derivatives. In the present study, we propose a synthesis strategy for ion-laminated boron layered materials in a solution phase, which enables the preparation of analogs by changing the alkali-metal species.

Mice Born to Mothers Fed a Diet High in Omega-6 Fatty Acids and Low in Omega-3 Fatty Acids During Pregnancy Exhibit Various Behavioral Changes Including Impaired Social Behaviors and Enhanced Recognition Memory.

Background: Modern dietary trends have led to an increase in foods that are relatively high in n-6 PUFAs and low in n-3 PUFAs. We previously reported that the offspring of mother mice that consumed a diet high in n-6 linoleic acid (LA) and low in n-3 α-linolenic acid (ALA), hereinafter called the LA/ALA diet, exhibited behavioral abnormalities related to anxiety and feeding.

Objectives: We currently lack a comprehensive overview of the behavioral abnormalities in these offspring, which was investigated in this study.

Nutritional Imbalance between Omega-6 and Omega-3 Polyunsaturated Fatty Acids during Pregnancy Increases the Number of Pyramidal Neurons in the Basolateral Amygdala and Anxiety-Related Behavior in Offspring.

Modern agriculture allows for the production of foods that are high in n-6 linoleic acid and low in n-3 α-linolenic acid (LA/ALA), which are suggested to be associated with an increased risk for the onset of anxiety disorders. However, there is not sufficient evidence to understand its underlying brain mechanism. Given that mouse offspring derived from mothers fed a LA/ALA diet during gestation and early lactation showed increased anxiety-related behaviors and that rodents exposed to a LA/ALA diet are more vulnerable to stress, in this study, we investigated the effects of maternal LA/ALA diet consumption on stress-induced anxiety-related behavior and the brain structures involved in the expression of negative emotional states in mouse offspring.

Steep medial posterior tibial slope angle and ramp lesion are independent risk factors for an increase in quantitatively measured pivot shift in patients with ACL-deficient knees.

Background: Delayed anterior cruciate ligament (ACL) reconstruction often causes residual anterolateral rotatory instability (ALRI) and consequent knee osteoarthritis, warranting the recommendation of early ACL reconstruction within 6 months after injury. Nonetheless, some cases show notable instability, even shortly after injury. The purpose of this study was to identify risk factors for an increase in quantitatively measured pivot shift in patients with ACL-deficient knees within 6 months after injury.

The association of the medial meniscus covering ratio with knee cartilage thickness at 15 medial compartment subregions as found by three-dimensional analysis using MRI.

Purpose: The correlation of cartilage thickness measured by three-dimensional (3D) magnetic resonance imaging (MRI) and the medial meniscal coverage ratio (MMCR), which presented pathology of the medial meniscus extrusion (MME) in 3D MRI, has not yet been elucidated. The study's purpose was to retrospectively verify whether the average cartilage thickness calculated by the automatic MRI 3D analysis system for each subregion was correlated with MMCR.

Methods: A total of 60 patients underwent medial meniscus repair or high tibial osteotomy to treat their medial knee osteoarthritis.

The deltoid ligament complex is reliably visualised as four fascicles in two layers with 3D volumetric MRI in the ankles of 20 asymptomatic volunteers.

Purpose: The anatomy of the deltoid ligament is complex. There is agreement on the presence of superficial and deep layers but the number and frequency of fascicles remains controversial. Identifying injuries to specific components of the deltoid ligament may inform decision-making on their management.

A comparison of abductor hallucis muscle activation and medial longitudinal arch angle during nine different foot exercises.

Background: Intrinsic foot muscles are known to support the medial longitudinal arch (MLA) and stabilize the foot, and they are activated with weight bearing and increased postural demand. Various types of intrinsic foot muscle training have been reported, but one of the most useful of these, the short foot exercise, is challenging to perform effectively and requires practice, making it difficult to implement in ordinary clinical settings.

Research Question: What are the differences in abductor hallucis longus (ABH) muscle activity and MLA angle during intrinsic foot muscle exercises that employ weight bearing and balancing conditions when they are performed with minimal practice?

Methods: Sixteen healthy volunteers performed nine different intrinsic foot muscle exercises, practiced once or twice.

Presoaking Grafts in Vancomycin Does Not Impair Graft-Bone Healing in a Rat Anterior Cruciate Ligament Reconstruction Model.

Background: The vancomycin presoaking technique (wherein grafts are treated with a vancomycin solution [VS] for anterior cruciate ligament reconstruction [ACLR]) reduces the infection rate after ACLR. However, the effects of this technique on graft-bone healing have not been fully elucidated.

Purpose: To investigate the effects of vancomycin presoaking on graft-bone healing in a rat ACLR model.

Characteristics of the synovial microenvironment and synovial mesenchymal stem cells with hip osteoarthritis of different bone morphologies.

Background: Variations in bone morphology in patients with hip osteoarthritis (HOA) can be broadly categorized into three types: atrophic, normotrophic, and hypertrophic. Despite the investigations examining clinical elements, such as bone morphology, pain, and range of motion, our understanding of the pathogenesis of HOA remains limited. Previous studies have suggested that osteophytes typically originate at the interface of the joint cartilage, periosteum, and synovium, potentially implicating synovial mesenchymal stem cells (SMSCs) in the process.

Low central sensitisation inventory score is associated with better post-operative outcomes of osteotomy around the knee.

Purpose: The purpose of this study was to investigate the potential association between central sensitisation inventory (CSI) scores and post-operative patient-reported outcomes (PROs) in patients underwent osteotomy around the knee (OAK), with a CSI cut-off score specific for knee osteoarthritis.

Methods: CSI scores were collected from 173 patients who underwent OAK, along with their knee injury and osteoarthritis outcome score (KOOS) and pain numeric rating scale (NRS) scores. Patients were divided into high-CSI score group and low-CSI score group with a cut-off score of 17.

Dietary palmitic acid to oleic acid ratio modulates energy metabolism and biological rhythms in young healthy Japanese males.

The present study investigated the potential role of the composition of dietary fatty acids in the regulation of biological rhythms, such as the sleep architecture, core body temperature and leukocyte clock gene expression, in subjects fed meals rich in palmitic acid (PA) or oleic acid (OA). Eleven males participated in two sessions of indirect calorimetry in a whole-room metabolic chamber. In each session, subjects consumed three meals rich in PA (44·3 % of total fat as PA and 42·3 % as OA) or OA (11·7 % of total fat as PA and 59·3 % as OA) in the metabolic chamber.

Suppressing Effects of Docosahexaenoic Acid-Containing Diets on Oxidative Stress and Fibrosis in 5/6 Nephrectomized Rats.

Key Points: Increased albuminuria on 5/6 nephrectomized rats, as reported earlier, is attenuated by arachidonic acid–containing and docosahexaenoic acid (DHA)–containing diets. This study established that DHA affects both oxidative stress and fibrosis in the kidney. DHA suppressed the oxidative stress and fibrosis, hence suppressing the progression of renal failure.

Hyaluronic acid sheet transplantation attenuates infrapatellar fat pad fibrosis and pain in a rat arthritis model.

Fibrosis of the infrapatellar fat pad (IFP) occurs after knee joint surgery or during knee osteoarthritis (KOA) and causes persistent pain and limited mobility. Previous studies demonstrated that treating IFP fibrosis alleviated pain in animal models. In this study, we examined the effects of hyaluronic acid (HA) sheet transplantation on IFP fibrosis and articular cartilage degeneration in a monoiodoacetic acid (MIA) rat arthritis model (95 male rats).

Individual fascicles of the ankle lateral ligaments and the lateral fibulotalocalcaneal ligament complex can be identified on 3D volumetric MRI.

Purpose: Lateral ligament ankle sprains are common and the anatomy on imaging studies is vital for accurate diagnosis. The lateral fibulotalocalcaneal ligament (LFTCL) complex consists of the inferior fascicle of the anterior talofibular ligament (ATFL) which is connected by arciform fibres with the calcaneofibular ligament (CFL). The superior fascicle of ATFL is an independent structure that should be assessed individually.

Characterization of the fatty acid profile in the ventral midbrain of mice exposed to dietary imbalance between omega-6 and omega-3 fatty acids during specific life stages.

Objective: Omega-6 (n-6) and omega-3 (n-3) polyunsaturated fatty acids (PUFAs) are essential nutrients. Dietary imbalance between these PUFAs, in particular high in n-6 PUFAs and low in n-3 PUFAs (n-6/n-3), is common in modern society. We have previously reported that C57BL/6 mouse male offspring derived from mothers exposed to an n-6/n-3 diet during the gestation had an augmented ventral midbrain dopamine system in adulthood; however, the fatty acid composition in this brain region has not yet been investigated.

Antifungal activity of dehydrocurvularin for Candida spp. through the inhibition of adhesion to human adenocarcinoma cells.

Cell adhesion plays a crucial role in candidiasis through invasion of the human body and obtaining resistance to drugs by forming biofilms. Cell adhesion thus is a critical target for combating candidiasis by preventing the entry of fungal hyphae into the epithelium. We report here that dehydrocurvularin (1), isolated from the marine-derived fungus Curvularia aeria, exhibited anti-fungal activities for Candida albicans and Candida auris.

Liquid crystalline 2D borophene oxide for inorganic optical devices.

Borophene has been recently proposed as a next-generation two-dimensional material with promising electronic and optical properties. However, its instability has thus far limited its large-scale applications. Here, we investigate a liquid-state borophene analogue with an ordered layer structure derived from two-dimensional borophene oxide.

Porous diaphragm syndrome presenting as hemothorax secondary to hemoperitoneum after laparoscopic myomectomy: A case report and literature review.

Porous diaphragm syndrome includes all pleural cavity conditions, including pleural effusion, hemothorax, or pneumothorax, that occur secondary to peritoneal cavity disorders through defects in the diaphragm. In this report, we describe the first known case of porous diaphragm syndrome presenting as hemothorax after laparoscopic myomectomy. A 46-year-old nulliparous woman underwent laparoscopic myomectomy for multiple fibroids.
