BACKGROUND: Tanning equipment use is related to the early onset of cancer, with the risk increasing as the duration and repetition of exposure increase. In 2009, the International Agency for Research on Cancer classified tanning equipment use as carcinogenic to humans, and according to the World Health Organization, the risk of skin melanoma increases significantly when use begins before age 35. DATA AND METHODS: The rapid response component of the 2014 Canadian Community Health Survey collected data on the use of tanning equipment in the previous 12 months, including reasons for use, frequency/duration of use, precautions taken, and adverse reactions or injuries...

Non-alcoholic fatty liver disease (NAFLD) comprises a range of liver diseases, between steatosis and non‑alcoholic steatohepatitis and liver cirrhosis, which are closely associated with diabetes mellitus. Previous studies have indicated that oxidative stress is a key factor in the development of NAFLD. Molecular hydrogen (H2) may ameliorate oxidative stress injuries by selectively neutralizing peroxynitrite and hydroxyl radicals. The present study evaluated the effects of H2 on NAFLD in rats and concluded that H2‑rich saline had significant therapeutic effects on NAFLD induced by hyperglycemia and hyperlipidemia, as demonstrated by hematoxylin and eosin and terminal deoxynucleotidyl-transferase‑mediated dUTP nick end labeling staining...

Among a number of clinical factors, bacterial infection is one of the most common causes of acute lung injury (ALI), a serious complication that carries a high risk of mortality (~40%). During the process of ALI, intense local and systemic inflammation is elicited, which exacerbates the injury. Neutrophil infiltration into airspace is observed in early stage of ALI, and is required for the full development of ALI through an array of mechanisms, including the release of granule contents and the production of pro‑inflammatory cytokines, due to the overactivation of complement and cytokines...

Diabetes mellitus (DM) is a chronic metabolic disease, where the predominant pathogenesis is pancreatic β‑cells dysfunction or injury. It has been well established that inflammation leads to a gradual exhaustion of pancreatic β‑cell function with decreased β‑cell mass likely resulting from pancreatic β‑cells apoptosis or death. Vitexin, a major bioactive flavonoid compound in plants has numerous pharmacological properties, including antioxidant, anti‑inflammatory and antimyeloperoxidase. Whether vitexin can protect pancreatic β‑cells against lipopolysaccharide (LPS)‑induced pro‑inflammatory cytokine production and apoptosis has received little attention...

Gap junctions are intercellular channels made of connexin proteins, mediating both electrical and biochemical signals between cells. The ability of gap junction proteins to regulate immune responses, cell proliferation, migration, apoptosis and carcinogenesis makes them attractive therapeutic targets for treating inflammatory and neoplastic disorders in different organ systems. Alterations in gap junction profile and expression levels are observed in hyperproliferative skin disorders, lymphatic vessel diseases, inflammatory lung diseases, liver injury and neoplastic disorders...

Chenxia Hu, Yong Huang, Lanjuan Li
Current research has demonstrated that mitochondrial morphology, distribution, and function are maintained by the balanced regulation of mitochondrial fission and fusion, and perturbation of the homeostasis between these processes has been related to cell or organ dysfunction and abnormal mitochondrial redistribution. Abnormal mitochondrial fusion induces the fragmentation of mitochondria from a tubular morphology into pieces; in contrast, perturbed mitochondrial fission results in the fusion of adjacent mitochondria...

STUDY DESIGN: A prospective study on cadaver specimens. OBJECTIVE: To explore why cement leakage from BF easily occurs during vertebral augmentation procedures. SUMMARY OF BACKGROUND DATA: Type B (through BF, basivertebral foramen) cement leakage is the most common type after vertebral augmentation, but the mechanism of this is still controversial. The contribution of vertebral trabecular bone orientation and trabecular damage during compression fracture to cement leakage is still unknown...

Nalini M Nadkarni
On July 3, 2015, Nalini Nadkarni, a world-renowned ecologist who had been studying the biologic processes of ecosystem disturbance and recovery, sustained a catastrophic 50-foot free-fall from the top of the rainforest canopy to the forest floor at her remote field research site. She lost consciousness in shock and sustained life-threatening injuries. Her accompanying students hiked out, radio-called 911, and the Harborview Medical Center (Seattle) Medivac team arrived 4 hours later to rescue her. Her prognosis was extremely grim; her family gathered in anticipation of her death as she underwent four operations during her 10 days in the ICU...

Obstetric practice carries a high risk of medical liability and involves both obstetricians and anesthesiologists. Analysis of data from the Anesthesia Closed Claims Project database shows an increase in the proportion of anesthesia claims for maternal death and brain damage between the 1990s and 2000 and later, primarily due to hemorrhage. The proportion of claims for newborn brain damage remained unchanged while those for maternal nerve injury and minor injuries decreased. Use of massive transfusion protocols and clinical drills have been shown to improve outcomes from hemorrhage...

INTRODUCTION: Liposarcoma is the most frequent type of retroperitoneal sarcomas. Dedifferentiated liposarcoma is the least common subtype and is an extremely rare tumor. CASE REPORT: We present the case of a 53-year-old male who was referred with a giant retroperitoneal mass. The patients' mass was deemed unresectable by the previous institution and received chemotherapy with no benefit. We macroscopically removed the 38x32 cm mass with right nefrectomy. Pathological examination revealed dedifferentiated liposarcoma...

Conjugation of Doxorubicin (DOX) to N-(2-Hydroxypropyl) methylacrylamide copolymer (HPMA) has significantly reduced the DOX-associated cardiotoxicity. However, the reports on the impact of HPMA-DOX conjugates on the cardiovascular system such as blood pressure (BP) and heart rate (HR) were in restrained animals using tail cuff and/or other methods that lacked the resolution and sensitivity. Herein, we employed radiotelemetric-spectral-echocardiography approach to further understand the in vivo cardiovascular hemodynamics and variability post administration of free DOX and HPMA-DOX...

OBJECTIVE/BACKGROUND: The Insomnia Severity Index (ISI) is a widely used self-report measure of insomnia symptoms. However, to date this measure has not been validated or well-characterized in veterans who have experienced traumatic brain injury (TBI). This study assessed the psychometric properties and convergent, divergent, construct, and discriminate validity of the ISI in veterans with a history of TBI. PARTICIPANTS: Eighty-three veterans with history of TBI were seen in the VA San Diego Healthcare System as part of a research protocol...

The use of stem or progenitor cells from bone marrow, or peripheral or umbilical cord blood is becoming more common for treatment of diabetic foot problems. These cells promote neovascularization by angiogenic factors and they promote epithelium formation by stimulating cell replication and migration under certain pathological conditions. We investigated the role of CD34 + stem cells from human umbilical cord blood in wound healing using a rat model. Rats were randomly divided into a control group and two groups with diabetes induced by a single dose of 55 mg/kg intraperitoneal streptozocin...

Impairments in visual perception are common after acquired brain injury (ABI) and adequate assessment is crucial for diagnosis and rehabilitation. However, there is no consensus yet on how to assess these disorders after ABI. The aim of the present study was to explore what measures are considered reasonable to be part of a test battery for the screening of a broad range of mid-level and higher-order visual perceptual disorders. A Delphi method was used to collect the opinions of 28 international multidisciplinary experts in visual perception in order to achieve consensus on the content of the test battery...

Alzheimer's Disease (AD) is the most common form of dementia in which the death of brain cells causes memory loss and cognitive decline. Several factors are thought to play roles in the development and course of AD. Existing medical therapies only alleviate and delay cognitive symptoms. Current research has been focused on developing antibodies to remove the targets of β-amyloid (Aβ) and tau protein. This approach has achieved removal of A, however, no long term success to AD patients reported. The biological properties of saffron, the dry stigma of the plant Crocus sativus L...

The clinical application of doxorubicin (Dox) is limited by its adverse effect of cardiotoxicity. Previous studies have suggested the cardioprotective effect of brain-derived neurotrophic factor (BDNF). We hypothesize that BDNF could protect against Dox-induced cardiotoxicity. Sprague Dawley rats were injected with Dox (2.5 mg/kg, 3 times/week, i.p.), in the presence or absence of recombinant BDNF (0.4 μg/kg, i.v.) for 2 weeks. H9c2 cells were treated with Dox (1 μM) and/or BDNF (400 ng/ml) for 24 hrs. Functional roles of BDNF against Dox-induced cardiac injury were examined both in vivo and in vitro...
