: The tendon-to-bone attachment (enthesis) is a complex hierarchical tissue that connects stiff bone to compliant tendon. The attachment site at the micrometer scale exhibits gradients in mineral content and collagen orientation, which likely act to minimize stress concentrations. The physiological micromechanics of the attachment thus define resultant performance, but difficulties in sample preparation and mechanical testing at this scale have restricted understanding of structure-mechanical function...

Scorpion envenomation causes an autonomic storm resulting in changes in the vasoactive mediators' levels which lead to myocardial damage, cardiovascular disturbances, peripheral circulatory failure, pulmonary edema, multi-system-organ-failure and death. The study aimed to determine the circulating levels of adrenaline, noradrenaline, angiotensin converting enzyme (ACE), Angiotensin II (Ang II), kallikrein enzyme, nitric oxide (NO), aldosterone, and electrolytes Na(+), K(+) and Ca(+2) in scorpion envenomed children and to evaluate the potential relation between these vasoactive mediators, the severity of scorpion envenoming and the clinical outcome of envenomed children...

BACKGROUND & AIMS: Concurrent to development of more effective drugs for treatment of hepatitis C virus (HCV), infection, there has been an increase in the incidence of non-alcoholic fatty liver disease (NAFLD). Data indicate that liver transplantation prolongs survival times of patient with acute hepatitis associated with alcoholic liver disease (ALD). We compared data on disease prevalence in the population with data from liver transplantation waitlists to evaluate changes in the burden of liver disease in the United States...

Urogenital tuberculosis is the second most frequent form of extrapulmonary tuberculosis. Starting with a pulmonary focus, 2 to 20% of patients develop urogenital tuberculosis through hematogenous spread to the kidneys, prostate, and epididymis; through the descending collecting system to the ureters, bladder, and urethra; and through the ejaculatory ducts to the genital organs. Urogenital tuberculosis occurs at all age ranges, but it is predominant in males in their fourth and fifth decades. It is a serious, insidious disease, generally developing symptoms only at a late stage, which leads to a diagnostic delay with consequent urogenital organ destruction; there are reports of patients with renal failure as their initial clinical presentation...

DEFINITION: Langerhans cell histiocytosis (LCH) is defined by the association of a clinical and radiological involvement and a biopsy of a pathological tissue. Extension: it can affect any organ or system of the body but most commonly the bone (80% of cases), the skin (33%) and the pituitary (25%). Other organs are concerned such as liver, spleen, hematopoietic system and the lungs (15% each), lymph nodes (5-10%) and central nervous system (CNS) excluding the pituitary (2-4%). Natural history: the natural history of the disease is very heterogeneous, ranging from auto-regressive lesions to a disease affecting multiple organs with fatal consequences, while some lesions may be responsible for permanent sequels...

Octopus vulgaris is a sedentary organism that inhabits coastal waters being exposed to anthropogenic compounds. Lead concentration in coastal environments reflects many processes and activities namely weathering, industrial and domestic discharges, and atmospheric deposition. Since lead isotopic composition is little affected by kinetic processes occurring between source and sink, its signature has been used to identify different Pb sources. After a short-term heavy rainfall, hundreds of octopus appeared dead in two Portuguese coastal areas...

BACKGROUND: Sarcoidosis is a systemic disease of unknown etiology, in which granulomas develop in various organs, including the skin, lungs, eyes, or heart. It has been reported that patients with sarcoidosis are more likely to develop panic disorder than members of the general population. However, there are many unknown factors concerning the causal relationship between these conditions. CASE PRESENTATION: We present the case of a 57-year-old woman who appeared to have panic disorder, as she experienced repeated panic attacks induced by transient complete atrioventricular block, associated with cardiac sarcoidosis...

During cytokinesis, a contractile ring generates the constricting force to divide a cell into two daughters. This ring is composed of filamentous actin and the motor protein myosin, along with additional structural and regulatory proteins, including anillin. Anillin is a required scaffold protein that links the actomyosin ring to membrane and its organizer, RhoA. However, the molecular basis for timely action of anillin at cytokinesis remains obscure. Here, we find that phosphorylation regulates efficient recruitment of human anillin to the equatorial membrane...

BACKGROUND: Chronic lung consolidation has a limited number of differential diagnoses requiring distinct managements. The aim of the study was to investigate how logical analysis of data (LAD) can support their diagnosis at HRCT (high-resolution computed tomography). METHODS: One hundred twenty-four patients were retrospectively included and classified into 8 diagnosis categories: sarcoidosis (n=35), connective tissue disease (n=21), adenocarcinoma (n=17), lymphoma (n=13), cryptogenic organizing pneumonia (n=11), drug-induced lung disease (n=9), chronic eosinophilic pneumonia (n =7) and miscellaneous (n=11)...

BACKGROUND: Vasopressin receptor-mediated vasoconstriction is considered to be involved in the pathogenesis of organ failure in acute-on-chronic liver failure (ACLF). PATIENTS AND METHODS: We studied the association between six single nucleotide polymorphisms (SNPs) of the vasopressin 1a receptor gene and the development of organ failure in 826 patients admitted for acute decompensation of liver cirrhosis (n=641) or ACLF (n=185). RESULTS: No associations were found for SNPs with the presence of circulatory or renal failure...

INTRODUCTION: The recommended daily intake of iodide, is 150 μg for adolescents and adults, 175 μg for pregnancy and 200 μg for lactation. Thyroid gland is an effective collector of iodine. EVIDENCE ACQUISITION: The active iodine uptake along the basolateral membrane of thyroid cell is followed by its transport to the apical edge of the cell and then to the follicle lumen. TSH acts through cAMP and stimulates NIS gene expression and protein synthesis. The major proportion of iodine in the thyroid gland is bound to Thyroglobulin...

Neonatal septicemia (NS) is a common cause of death of newborn infants, hence early diagnosis and treatment are of the utmost importance. However, lack of specific clinical symptoms and late detection delay a correct diagnosis. It is therefore of great importance to establish auxiliary indexes for the early diagnosis of NS. To evaluate the value of interleukin (IL-6 and IL-8) in the diagnosis of NS, a prospective study was carried out. Seventy-five newborns who developed septicemia and received treatment in our hospital from January 2013 to December 2014 were selected as research subjects; also, 50 healthy newborns were set as a control group...

Nutritional deficiencies are very common among the patient on chronic hemodialysis. But they can be easily overlooked or misdiagnosed. Deficiencies of trace elements and phosphorous is rare among this patient population but if neglected can lead to catastrophic effects. We describe a case report of a patient with ESRD recently started on outpatient maintenance hemodialysis, who presented with life threatening muscular weakness with respiratory failure requiring prolonged mechanical ventilation. On initial workup, it was unclear what the cause of her weakness was, however, further investigations showed undetectable phosphorous levels as well as very low levels of trace elements...

Telomeres are located at each end of eukaryotic chromosomes. Their functional role is genomic stability maintenance. The protective role of telomeres depends on various factors, including number of nucleotides repeats, telomere-binding proteins, and telomerase activity. Organ transplantation is the preferred replacement therapy in the case of chronic kidney disease and the only possibility of sustaining recipients' life in the case of advanced liver failure. While the prevalence of acute rejection is constantly decreasing, prevention of transplanted organ long-term function loss is still challenging...

Cancer remains a leading cause of mortality and morbidity worldwide. In addition to organ failure, the most frequent reasons for admission of cancer patients to intensive care units (ICU) are: infections and sepsis. As critically ill, the complexity of the health situation of cancer patients renders the standard antimicrobial regimen more complex and even inadequate which results in increased mortality rates. This is due to pathophysiological changes in the volume of distribution, increased clearance, as well as to organ dysfunction...

Unlike somatic cells mitosis, germ cell meiosis consists of two consecutive rounds of division that segregate homologous chromosomes and sister chromatids, respectively. The meiotic oocyte is characterized by an absence of centrioles and asymmetric division. Centriolin is a relatively novel centriolar protein that functions in mitotic cell cycle progression and cytokinesis. Here, we explored the function of centriolin in meiosis and showed that it is localized to meiotic spindles and concentrated at the spindle poles and midbody during oocyte meiotic maturation...

OBJECTIVE: Canine babesiosis is a common and clinically significant tick-borne disease caused by haemoprotozoan parasites of the genus Babesia. Acute renal failure is considered to be one of the most prevalent complications of canine babesiosis. This complication leads to a decrease in the glomerular filtration rate and in consequence causes azotemia and uremia. The objective of this study was to assess the localization and extent of renal damage in dogs infected with Babesia canis using an urinary marker for glomerular (urinary immunoglobulin G, uIgG), proximal tubular dysfunction (urinary retinol binding protein, uRBP) and distal tubular dysfunction (urinary Tamm-Horsfal protein, uTHP)...

REVIEW
Steven A Conrad, Peter T Rycus
Extracorporeal cardiopulmonary resuscitation (ECPR) is the use of rapid deployment venoarterial (VA) extracorporeal membrane oxygenation to support systemic circulation and vital organ perfusion in patients in refractory cardiac arrest not responding to conventional cardiopulmonary resuscitation (CPR). Although prospective controlled studies are lacking, observational studies suggest improved outcomes compared with conventional CPR when ECPR is instituted within 30-60 min following cardiac arrest. Adult and pediatric patients with witnessed in-hospital and out-of-hospital cardiac arrest and good quality CPR, failure of at least 15 min of conventional resuscitation, and a potentially reversible cause for arrest are candidates...
