High-carbon martensite steels (with C > 0.5 wt.%) are very hard but at the same time as brittle as glass in as-quenched or low-temperature-tempered state. Such extreme brittleness, originating from a twin microstructure, has rendered these steels almost useless in martensite state. Therefore, for more than a century it has been a common knowledge that high-carbon martensitic steels are intrinsically brittle and thus are not expected to find any application in harsh loading conditions. Here we report that these brittle steels can be transformed into super-strong ones exhibiting a combination of ultrahigh strength and significant toughness, through a simple grain-refinement treatment, which refines the grain size to ~4 μm...

The coupling between structural phase transformations and dislocations induces challenges in understanding the deformation behavior of metallic cerium at the nanoscale. In the present work, we elucidate the underlying mechanism of cerium under ultra-precision diamond cutting by means of molecular dynamics modeling and simulations. The molecular dynamics model of diamond cutting of cerium is established by assigning empirical potentials to describe atomic interactions and evaluating properties of two face-centered cubic cerium phases...

Background Fractures or fracture dislocations of the proximal interphalangeal joint often occur during sports or accidents. Dislocations of the PIP-joint are the most common ligamentary injuries of the hand. As this kind of injury is so frequent, hand surgeons and other physicians should be aware of the correct treatment. Objectives This paper summarises the most common injury patterns and the correct treatment of PIP-joint dislocations. Materials and Methods This paper reviews the current literature and describes the standardised treatment of PIP-joint dislocations...

RATIONALE: Megalophthalmos anterior is a rare, bilateral, nonprogressive, hereditary, congenital disorder, characterized by the enlargement of all anterior segment structures of the eye, with megalocornea, iris atrophy, and zonular abnormalities commonly found. Usually almost asymptomatic in young patients, with most complaints concerning blurred vision due to the common corneal astigmatism, it might in time lead to several complications including premature cataract formation and pigmentary glaucoma...

BACKGROUND: Traumatic injuries to the tarsometatarsal or Lisfranc joints can be complex problems associated with long-term morbidity. Currently there is no clear consensus regarding optimal fixation methods. The purpose of this study was to evaluate the association between time from injury to treatment and treatment method with outcome. It is hypothesized that patients who underwent open reduction internal fixation (ORIF) more acutely would have higher return to duty rates. METHODS: This study is a retrospective review of 171 low-energy closed tarsometatarsal dislocations and fracture dislocations in patients identified using a Department of Defense trauma registry...

The ciliary zonules link the lens to the ciliary body in the eye, controlling the thickness of the lens for focusing through their characteristic elasticity. The ciliary zonules are composed of oxytalan fibers. Physiological or pathological damage to the ciliary zonules, including exposure to ultraviolet (UV)-A and UV-B components, can lead to lens dislocation. However, no studies have shown whether UV affects the ciliary zonule. Here, we assessed the effects of UV light on human nonpigmented ciliary epithelial cells (HNPCECs)...

Misfolded ER proteins are dislocated towards the cytosol and degraded by the ubiquitin-proteasome system in a process called ER-associated protein degradation (ERAD). During infection with human cytomegalovirus (HCMV), the viral US2 protein targets HLA class I molecules (HLA-I) for degradation via ERAD to avoid elimination by the immune system. US2-mediated degradation of HLA-I serves as a paradigm of ERAD and has facilitated the identification of TRC8 as an E3 ubiquitin ligase. To date, no specific E2 enzymes had been described for cooperation with TRC8...

INTRODUCTION: Permanent dislocation of the patella (PDP) is a rare condition. In cases of PDP with tibiofemoral arthritis, total knee arthroplasty may be performed through a medial parapatellar approach with patellar realignment. In this article we present two cases of PDP with tibiofemoral osteoarthritis successfully treated via lateral approach TKA without any additional realignment procedure. We performed two total knee arthroplasties for PDP with lateral tibiofemoral arthritis through a lateral approach without any realignment procedure...

The systematic study of the ionic transport properties of epitaxial Y2Zr2O7 films with defective fluorite structure reveals an enhanced oxygen vacancy conductivity at the interface between the films and the MgO (110) substrate, which is characterized by a high density of misfit dislocations. This beneficial effect is discussed in terms of space charge and mobility effects.

The irreducible dislocation of the hallux interphalangeal joint is an infrequent condition and only a few cases have been described. It presents as dorsal dislocation with interposition of the sesamoid bone, which has the possibility of being radiologically undetectable. We present the case of a 29 year-old patient who, after a sports trauma sustained a hallux interphalangeal dislocation that went unnoticed for eight days. Since, closed reduction was not possible, as occurred in several cases reported in the literature, open reduction was performed through a dorsal incision...

BACKGROUND: Shoulder dislocation is a common reason for admission in the emergency room. Its recurrence rate may be as high as 96% due to the associated bone lesions. The purpose of this study is to identify the underreporting of lesions comparing those identified in the initial X-ray with those identified in the post-reduction X-ray. MATERIAL AND METHODS: X-rays of 46 patients with suspected anterior glenohumeral dislocation were assessed for diagnostic purposes and to identify the initial bone lesions...

AIM OF STUDY: This article aims to summarize the treatment methods for shoulder dislocations supported by Ambroise Paré, and his clinical and academic contribution to this subject. INTRODUCTION: Ambroise Paré (1510-1590) was one of the most prominent surgeons of his time, and one of the most significant innovators of the Renaissance in the fields of military operation, bandages, wound healing, bloodletting, close blood vessels techniques and cesarean section. For many, he is considered "the Father of Modern Surgery"...

PURPOSE: Recurrent patellar dislocation is currently treated with anatomical reconstruction of the medial patellofemoral ligament (MPFL), and favourable postoperative outcomes have been reported. However, it is uncertain if healthy MPFL function is restored by anatomical reconstruction. The hypothesis in this study was that stabilization of the patella following MPFL reconstruction would be improved compared with that before surgery, but that function of the grafted tendon would differ from that of a healthy MPFL...

Bipolar dislocation of the clavicle is rare. In the literature, every reported bipolar dislocation of the clavicle is caused by a traumatic injury with loss of function of the affected shoulder. Currently, there is no recommendation to treat. A conservative treatment can be tried first to achieve adequate shoulder function. If this cannot be achieved, surgical treatment will be indicated. In the literature, many options for surgical treatment are described. This article presents a case of a chronic Rockwood V injury with chronic anterior sternoclavicular joint instability...

BACKGROUND: Total hip replacement for high dislocation of the hip presents some difficulties, considering patients' young ages, the abnormal hip anatomy and the high rate of complications. In this study, we present our experience in terms of clinical and radiological results in the treatment of Crowe type IV hips with subtrochanteric femoral shortening osteotomy and cementless total hip replacement. MATERIALS AND METHODS: We retrospectively reviewed 15 patients with Crowe type IV hip dysplasia (two bilateral cases for a total of 17 hips) treated with cementless total hip replacement associated with shortening subtrochanteric osteotomies (nine transversal and eight Z-shape osteotomies) between March 2000 to February 2006...

Accumulating evidence has defined nucleophosmin 1 (NPM1) mutation as a driver genetic event in acute myeloid leukemia (AML), whereas the pathogenesis of NPM1-mutated AML remains to be fully elucidated. In this study, we showed that mutant NPM1 elevated autophagic activity and autophagic activation contributed to leukemic cell survival in vitro. Meanwhile, we also found high expression of promyelocytic leukemia gene (PML) and its cytoplasmic dislocation in primary NPM1-mutated AML blasts and NPM1-mA positive OCI-AML3 cells...

BACKGROUND CONTEXT: Distractive-flexion injuries (DFIs) of the subaxial cervical spine are major contributors to spinal cord injury (SCI). Prompt assessment and early intervention of DFIs associated with SCI is crucial to optimize patient outcome; however, neurological examination of patients with subaxial cervical injury is often difficult, as patients commonly present with reduced levels of consciousness. Therefore, it is important to establish potential associations between injury epidemiology and radiographic features, and neurological involvement...
