Head and neck squamous cell carcinoma (HNSCC) is a highly heterogeneous and aggressive tumor originating from the epithelial lining of the upper aero-digestive tract accounting for 300,000 annual deaths worldwide due to failure of current therapies. The natural killer group 2D (NKG2D) receptors on natural killer (NK) cells and several T cell subsets play an important role for immunosurveillance of HNSCC and are thus targeted by tumor immune evasion strategies in particular by shedding of various NKG2D ligands (NKG2DLs)...

Severe leptospirosis can be a rare cause of acute respiratory distress syndrome (ARDS) and multiorgan failure. A patient who made an impact on how I practice was a case of severe leptospirosis (Weil's disease) that presented as ARDS in the ICU. Leptospirosis is an under-reported infectious disease worldwide and should be considered as a cause of ARDS especially in patients with exposure history complicated with diffuse alveolar bleeding (DAH), icteric hepatitis and renal deterioration. Empiric treatment should be recommended before confirmation of laboratory tests as serological diagnosis is time consuming...

Hepatopulmonary syndrome (HPS) is a serious complication of advanced liver disease, which markedly increases mortality. Pulmonary vascular remodelling (PVR) induced by circulating mediators plays an important role in the pathogenesis of HPS, while the underlying mechanism remains undefined. In the present study, we reported that endothelin-1 (ET-1) is up-regulated and annexin A1(ANXA1) is down-regulated in HPS rat, and ET-1 decreases the ANXA1 expression in a dose-dependent manner in rat pulmonary arterial smooth muscle cells (PASMCs)...

INTRODUCTION: Leptospirosis is a zoonotic infection that typically presents with fever, myalgias, nausea, and vomiting after contact with contaminated waters or infected animals (typically rodents); and their excrements. Conditions favorable to the transmission of leptospirosis are common in LA and, without treatment, leptospirosis can lead to both liver and renal failure, meningitis, pulmonary hemorrhage and ultimately death. CASE: A 56 year old woman with no past medical history presented to the Emergency Department with weakness, myalgias, jaundice and decreased urine output for one week...

BACKGROUND: The role of thymectomy in the treatment of juvenile myasthenia gravis (JMG) is poorly defined. The objective of this systematic review was to evaluate the effect of thymectomy on survival, disease severity, and peri-operative complications for patients with JMG. METHODS: A search of MEDLINE, EMBASE, and the Cochrane Library (1/1/2000-3/1/2016) identified all English language, human studies of thymectomy for JMG. The population was patients with JMG age ≤18 years who underwent thymectomy (comparator group was unexposed to thymectomy)...

Owing to interpatient variability in busulfan exposure, therapeutic monitoring of busulfan is often used in myeloablative allogeneic transplantation to ensure that patients are near the optimal steady-state goal of 900 ng/mL. One challenge in therapeutic monitoring of busulfan is the brief course of busulfan treatment, requiring prompt analysis and dose adjustments as needed. Pharmacokinetic evaluation of a busulfan test dose before the start of the conditioning regimen would allow for all conditioning regimen doses to be given at the calculated optimized dose...

Several aquaporin (AQP )-type water channels are expressed in kidney: AQP1 in the proximal tubule, thin descending limb of Henle, and vasa recta; AQP2 -6 in the collecting duct; AQP7 in the proximal tubule; AQP8 in the proximal tubule and collecting duct; and AQP11 in the endoplasmic reticulum of proximal tubule cells. AQP2 is the vasopressin-regulated water channel that is important in hereditary and acquired diseases affecting urine-concentrating ability. The roles of AQPs in renal physiology and transepithelial water transport have been determined using AQP knockout mouse models...

BACKGROUND: Incontinentia pigmenti (IP; MIM308300) is a severe, male-lethal, X-linked, dominant genodermatosis resulting from loss-of-function mutations in the IKBKG gene encoding NF-κB essential modulator (NEMO, the regulatory subunit of the IKK complex). In 80% of cases of IP, the deletion of exons 4 to 10 leads to the absence of NEMO and total inhibition of NF-κB signaling. Here, we described a new IKBKG mutation responsible for IP resulting in an inactive truncated form of NEMO...

Leptospirosis is one of the most widespread zoonoses in the world, and its most severe form in humans, "Weil's disease," may lead to jaundice, hemorrhage, renal failure, pulmonary hemorrhage syndrome, and sometimes,fatal multiple organ failure. Although the mechanisms underlying jaundice in leptospirosis have been gradually unraveled, the pathophysiology and distribution of leptospires during the early stage of infection are not well understood. Therefore, we investigated the hamster leptospirosis model, which is the accepted animal model of human Weil's disease, by using an in vivo imaging system to observe the whole bodies of animals infected with Leptospira interrogans and to identify the colonization and growth sites of the leptospires during the early phase of infection...

Amyotrophic Lateral Sclerosis (ALS) is an incurable motor neurodegenerative disease caused by a diversity of genetic and environmental factors leading to neuromuscular degeneration and pathophysiological implications in non-neural systems. Our previous work showed abnormal transcriptional expression levels of biomarker genes in non-neuronal cell samples from ALS patients. The same genes proved to be differentially expressed in brain, spinal cord and muscle of the SOD1(G93A) ALS mouse model. These observations support the pathophysiological relevance of the ALS biomarkers discovered in human mesenchymal stem cells (hMSC) isolated from bone marrow samples of ALS patients (ALS-hMSC)...

BACKGROUND: Acute kidney injury (AKI) after cardiac surgery is associated with increased morbidity and mortality. The long-term association between AKI and end-stage renal disease (ESRD) in an Asian population is unknown. Given the high prevalence of diabetes and a younger age of presentation for cardiac surgery, it is important to track this progression of kidney disease. Therefore, we studied the long-term risk of ESRD and mortality in our Asian patients who developed AKI after cardiac surgery...

Danon disease is a genetic deficiency in lysosome-associated membrane protein 2 (LAMP-2), a highly glycosylated constituent of the lysosomal membrane and characterized by a cardiomyopathy, skeletal muscle myopathy, and cognitive impairment. Patients, however, often manifest hepatic abnormalities, but liver function has not been well evaluated and the syndrome is relatively uncommon. Hence, we have taken advantage of a rat that has been deleted of LAMP-2 to study the relative role of LAMP-2 on liver function...

REVIEW
J-L Besse
The causes of metatarsalgia are classified as primary, secondary, and iatrogenic. Anatomical and biomechanical considerations separate "static" from "propulsive" forms of metatarsalgia. The physical examination should be combined with an assessment of weight-bearing radiographs and, if needed, of ultrasound or magnetic resonance imaging scans. The first-line treatment is conservative (stretching exercises, footwear modification, insoles, and lesion debridement). Soft-tissue surgical procedures (gastrocnemius muscle recession, tendon transfer, and plantar plate repair) should also be considered...

The analysis of DNA methylation and MTase activities is very important in the early clinical diagnosis of cancer, on purposes of providing insights into the mechanism of gene repression and developing novel drugs of treating methylation-related diseases. Combining the dendritic rolling circle amplification and Mg(2+)-dependent DNAzyme with a function of catalyzing the generation of a fluorophore-labeled nucleic acid acting as readout signal for the analyses, a new fluorescent method for DNA methyltransferase detection was reported...

Intracerebral injections are an invasive method to bypass the blood brain barrier and are widely used to study molecular and cellular mechanisms of the central nervous system. The administered substances are injected directly at the site of interest, executing their effect locally. By combining injections in the rat brain with state-of-the-art electron microscopy, subtle changes in ultrastructure of the nervous tissue can be detected prior to overt damage or disease. The protocol presented here involves stereotactic injection into the corpus callosum of Lewis rats and the cryopreparation of freshly dissected tissue for electron microscopy...
