Ramp lesions of the medial meniscus are associated with greater preoperative anterior knee laxity in anterior cruciate ligament injury.

Purpose: To assess the incidence of ramp lesions in anterior cruciate ligament (ACL) injuries and to compare preoperative knee laxity between the patients with and without ramp lesions by using an electromagnetic measurement system (EMS).

Methods: Two hundred six patients who underwent primary ACL reconstruction with preoperative EMS measurements were retrospectively enrolled in the present study. The diagnoses of the ramp lesions were made by arthroscopic inspections.

Effect of Radon Inhalation on Murine Brain Proteins: Investigation Using Proteomic and Multivariate Analyses.

Radon is a known risk factor for lung cancer; however, it can be used beneficially, such as in radon therapy. We have previously reported the enhancement of antioxidant effects associated with trace amounts of oxidative stress as one of the positive biological effects of radon inhalation. However, the biological effects of radon inhalation are incompletely understood, and more detailed and comprehensive studies are required.

Description of two new species from South Korea.

Based on molecular markers, mating experiments, morphological observations and ecological data, two species (Nematoda: Diplogastridae) new to science are described. Both were collected from different Scarabaeoid beetles in South Korea, have a gonochoristic mode of reproduction and fall into a sub-clade of the clade. n.

Male-Specific Substances Possibly Contributing to Nuptial Flight of the Japanese Carpenter Ant Camponotus japonicus (Hymenoptera: Formicidae).

The nuptial flight of ants usually occurs during certain periods of the year. Alate females and males fly out of their nests to mate simultaneously. In the genus Camponotus, sex-specific chemicals are deposited in the male head; however, their roles in nuptial flight have not yet been clarified.

Injuries to both anterolateral ligament and Kaplan fiber of the iliotibial band do not increase preoperative pivot-shift phenomenon in ACL injury.

Background: To assess the incidence of anterolateral ligament (ALL) and Kaplan fiber of the iliotibial band (KF) injuries in patients with acute anterior cruciate ligament (ACL) injury on magnetic resonance imaging (MRI), and to investigate the association between these injuries and the magnitude of preoperative pivot-shift test.

Method: One-hundred and five patients with primary ACL injury were retrospectively reviewed. ALL injury and KF injury were assessed by preoperative MRI, and subjects were allocated into four groups: Group A, neither injury; Group B, only ALL injury; Group C, only KF injury; Group D, simultaneous ALL and KF injuries.

Long-term Experience on Breast Cancer-related Lymphedema in the Coastal Area of Fukushima, Japan After the 2011 Triple Disaster.

Background/aim: Disasters can jeopardize breast cancer care and Japan's triple disaster in 2011 (earthquake, tsunami, and nuclear accident) is no exception. However, detailed information is lacking regarding the care of breast cancer related lymphedema (BCRL) following the disaster. We aimed to explore the process by which local patients become aware of BCRL, the problems faced, and the support they require.

Clinical outcomes of arthroscopic lateral ligament repair using a knotless anchor for chronic lateral ankle instability.

Background/objective: Arthroscopic lateral ligament repair (ALLR) for chronic lateral ankle instability (CLAI) has been improving with technical innovations. However, there is a lack of information regarding mid- and/or long-term clinical outcomes after the introduction of ALLR. This study aimed to report mid-term clinical outcomes of ALLR with a knotless anchor.

Telepathology in intraoperative frozen section consultation of breast cancer sentinel node biopsy in Fukushima, Japan following the 2011 triple disaster: diagnostic accuracy and required time during the early implementation phase.

In breast cancer surgery, some medical facilities lack the necessary resources to conduct sentinel lymph node biopsy and its intraoperative frozen section consultation. In the coastal rural area of Fukushima, Japan, which has suffered from physician undersupply following the 2011 triple disaster of earthquake, tsunami and nuclear disaster, we explored the feasibility of telepathology by evaluating the diagnostic accuracy in remote intraoperative frozen section consultation of sentinel lymph node biopsy and its required time. Although examination time has room for improvement, telepathology can be one possible solution in resource-limited areas.

The necessity of proactive measures from healthcare providers highlighted by delayed breast cancer diagnosis due to COVID-19: A case report.

Key Clinical Message: During disasters, multiple factors can cause significant delays in medical visits. Regular patient monitoring, high-risk individual alerts, and telemedicine enhancements can potentially alleviate these issues and ensure timely interventions.

Abstract: During the COVID-19 pandemic, a Japanese woman in her 70s delayed her regular breast cancer checkup for over 2 years.

Highlighting Potential Physical and Chemical Cues Involved in Conspecific Recognition System in a Predator Nematode, Seinura caverna.

Conspecific recognition is the ability to distinguish and respond to individuals of the same species. In nematodes, this behavior can mediate aggregation, feeding behavior, or mating. Here, we investigated whether and how the predatory nematode Seinura caverna recognizes and avoids conspecifics to prey on.

First record of (Ascomycota: Laboulbeniales) on Drosophilidae from Japan.

Three species were detected on five drosophilid species from Japan. We report on and , on and , and on . Except for , each of these species is a newly identified host.

The developmental and structural uniqueness of the embryo of the extremophile viviparous nematode, .

Viviparity, a reproductive form that supplies nutrients to the embryo during gestation, has repeatedly and independently occurred in multiple lineages of animals. During the convergent evolution of viviparity, various modifications of development, structure, and physiology emerged. A new species of nematode, , was discovered in the alkaline, hypersaline, and arsenic-rich environment of Mono lake.

Reliability and validity of the Forgotten Joint Score-12 for total ankle replacement and ankle arthrodesis.

Objectives: This study evaluated the reliability and validity of the Forgotten Joint Score-12 (FJS-12)-a measure of patients' ability to forget their joints in daily life-in patients who underwent total ankle replacement (TAR) or ankle arthrodesis (AA).

Methods: Patients who underwent TAR or AA were recruited from seven hospitals. The patients completed the Japanese version of FJS-12 twice, at an interval of two weeks, at a minimum of one year postoperatively.

Ultrastructural study of anther parasitism of by (Aphelenchoididae).

Transmission electron microscopy (TEM) was used to compare the ultrastructural differences between healthy male florets (anthers) and one floret parasitized by in late phase C syconia of from southern Florida. Previous light-microscopic examination of paraffin-sectioned material showed that -infested anthers of manifested as malformed, often with aberrant pollen and hypertrophied epidermal cells closest to regions containing propagating nematodes. Female florets or fig wasp-parasitized female florets were not observed to be parasitized by nematodes.

Nematode and Strepsipteran Parasitism in Bait-Trapped and Hand-Collected Hornets (Hymenoptera, Vespidae, ).

The parasitism of two groups of host-manipulating parasites of hornets was examined in Kyoto, Japan. (661 individuals), (303), (457), (158), (57), and (4) were collected either by bait trap or hand collection with an insect net, and examined for their parasites. An endoparasitic nematode, was isolated from three overwintered gynes of and a gyne of .

Onthodiplogaster japonica n. gen., n. sp. (Rhabditida: Diplogastridae) isolated from Onthophagus sp. (Coleoptera: Scarabaeidae) from Japan.

A diplogastrid nematode was isolated from a dung beetle, Onthophagus sp., collected from a rotten mushroom in Kyoto, Japan. The species is characterised by its cheilostomatal shape, separated into 12 narrow plates (rugae), deep stegostom, large ellipsoidal amphids, conical female tail and characteristic receptaculum seminis in the female.
