Functional Assessment of Meniscus Extrusion, Excursion and Hoop Strain UnderClinicallyRelevantLoadedRangeofMotionConditions inMeniscus-IntactandMeniscusRoot-DeficientKneesUsingaNovelBiomechanicalModel.

The knee is meniscus-dependent, relying on the tissue's biomechanical properties to maintain joint health and function. Meniscus dysfunction has primarily been assessed by measuring tibiofemoral articular contact areas and pressures, which entail important limitations. Meniscus extrusion, excursion, and hoop strain are dynamic measures of meniscal function, which have potential advantages for clinically applicable biomechanical testing of meniscus.

Virulence and biocontrol potential of entomopathogenic nematodes against soil-dwelling stages of the small hive beetle under laboratory and semi-field conditions.

Background: The small hive beetle (SHB; Aethina tumida) is a significant pest affecting honey bees and the global beekeeping industry. The harmful effects of chemical pesticides on bee health, non-target species and ecosystems highlight the need for sustainable SHB control methods. Soil applications of entomopathogenic nematodes (EPNs) targeting the soil-dwelling life stages (wandering larvae, pupae and emerging adults) of SHB present a promising biological control approach.

Diagnosis and Classification of Follicular Lymphoma and Related Entities.

Follicular lymphoma (FL) is a mature B cell neoplasm classically characterized by B cells harboring the t(14;18) IGH::BCL2 leading to the overexpression of BCL2 in most cases. Conventional FL occurs in lymph nodes and typically shows a follicular B-cell proliferation expressing at least one germinal center marker. Two early lesions closely related to conventional FL are recognized as variants, namely in situ follicular neoplasia (ISFN), and duodenal-type follicular lymphoma (DTFL).

Atypical Femur Fracture in a Teenager on Chronic Imatinib Therapy.

Atypical femoral fractures (AFFs) are rare fractures usually associated with medications that can ultimately alter bone metabolism. Imatinib, a drug prescribed for treatment of chronic myeloid leukemia (CML), has been associated with altered bone homeostasis, however, with unknown clinical significance. Here, we present the case of a 17-year-old female, with a diagnosis of CML undergoing chronic imatinib therapy, who developed an AFF treated successfully with prophylactic fixation with intramedullary nailing.

Extrasinusoidal macrophages are a distinct subset of immunologically active dural macrophages.

Although macrophages in the meningeal compartments of the central nervous system (CNS) have been comprehensively characterized under steady state, studying their contribution to physiological and pathological processes has been hindered by the lack of specific targeting tools in vivo. Recent findings have shown that the dural sinus and its adjacent lymphatic vessels act as a neuroimmune interface. However, the cellular and functional heterogeneity of extrasinusoidal dural macrophages outside this immune hub is not fully understood.

A Bedside-to-Bench-to-Bedside Journey to Advance Osteochondral Allograft Transplantation towards Biologic Joint Restoration.

More than 70 million adults in the United States are impacted by osteoarthritis (OA). Symptomatic articular cartilage loss that progresses to debilitating OA is being diagnosed more frequently and earlier in life, such that a growing number of active patients are faced with life-altering health care decisions at increasingly younger ages. Joint replacement surgeries, in the form of various artificial arthroplasties, are reliable operations, especially for older (≥65 years), more sedentary patients with end-stage OA, but have major limitations for younger, more active patients.

Procognitive and neurotrophic benefits of α5-GABA-A receptor positive allosteric modulation in a β-amyloid deposition mouse model of Alzheimer's disease pathology.

Reduced somatostatin (SST) and SST-expressing GABAergic neurons are well-replicated findings in Alzheimer's disease (AD) and are associated with cognitive deficits. SST cells inhibit pyramidal cell dendrites through α5-GABA-A receptors (α5-GABAA-R). α5-GABAAR positive allosteric modulation (α5-PAM) has procognitive and neurotrophic effects in stress and aging models.

Evaluation of Dexamethasone-Eluting Cell-Seeded Constructs in a Preclinical Canine Model of Cartilage Repair.

In this 12-month long, preclinical large animal study using a canine model, we report that engineered osteochondral grafts (comprised of allogeneic chondrocyte-seeded hydrogels with the capacity for sustained release of the corticosteroid dexamethasone [DEX], cultured to functional mechanical properties, and incorporated over porous titanium bases), can successfully repair damaged cartilage. DEX release from within engineered cartilage was hypothesized to improve initial cartilage repair by modulating the local inflammatory environment, which was also associated with suppressed degenerative changes exhibited by menisci and synovium. We note that not all histological and clinical outcomes at an intermediary time point of three months paralleled 12-month outcomes, which emphasizes the importance of studies in valid preclinical models that incorporate clinically relevant follow-up durations.

Metal punch vs. drill for rotator cuff anchor socket creation: cadaveric and clinical comparisons.

Background: Arthroscopic rotator cuff repair has been shown to decrease pain and increase function of certain rotator cuff tears. One potential source of pain is the technique used for bone tunnel creation in the humerus prior to suture anchor placement. This study compared the standard metal punch method to a continuous drilling method for tunnel creation prior to subsequent suture anchor placement.

Biodiversity impacts of the 2019-2020 Australian megafires.

With large wildfires becoming more frequent, we must rapidly learn how megafires impact biodiversity to prioritize mitigation and improve policy. A key challenge is to discover how interactions among fire-regime components, drought and land tenure shape wildfire impacts. The globally unprecedented 2019-2020 Australian megafires burnt more than 10 million hectares, prompting major investment in biodiversity monitoring.

Refining Diagnostic Subtypes of Peripheral T-Cell Lymphoma Using a Multiparameter Approach.

Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of neoplasms, with many cases remaining unclassifiable and categorized as PTCL-not otherwise specified (PTCL-NOS). Gene expression profiling (GEP) has delineated 2 prognostic subtypes within PTCL-NOS, PTCL-TBX21 and PTCL-GATA3, characterized by distinctive transcriptomes and a different prognosis. To further evaluate the pathologic features of these subgroups, 101 PTCL cases that did not meet specific criteria for well-defined T-cell lymphoma entities underwent detailed pathologic, immunophenotypic (including T follicular helper [T] biomarkers), and GEP analyses, separating them into PTCL-NOS (n = 63) and PTCL-TFH (also known as nodal PTCL-TFH, NOS, and TFH lymphoma, NOS) (n = 38).

Development and validation of a preclinical canine model for early onset fracture-related infections.

Fracture-related infections (FRIs) are a challenging complication in orthopaedics. Standard of care management for FRIs typically involves prolonged antibiotic therapies, irrigation and debridement (I&D) of the fracture site, and retention of fracture-fixation implants with or without exchange. Unfortunately, this treatment regimen is associated with treatment failure rates of up to 38 %, such that improved preventive and therapeutic interventions are needed.

Mating receptivity mediated by endosymbiont interactions in a haplodiploid thrips species.

Many arthropods carry maternally inherited endosymbionts that cause cytoplasmic incompatibility (CI), manifested as embryonic mortality in matings of infected males with uninfected females. Infected females, however, do not suffer this cost. Therefore, in populations with mixed endosymbiont infections, selection is expected to favour mechanisms that enable hosts to avoid or mitigate CI.
