BACKGROUND: Superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis is the standard treatment for Moyamoya disease (MMD). Cerebral hyperperfusion syndrome is a potential complication of this procedure and can cause local vasogenic edema and/or delayed intracerebral hemorrhage. Cerebral hypoperfusion is a contradictory postoperative pathophysiological condition implicated in MMD, but its association with symptomatic local vasogenic edema has not been reported. CASE REPORT: A 31-year-old woman with MMD underwent left STA-MCA anastomosis 3 months after a minor completed stroke in bilateral hemispheres...

Irritable bowel syndrome (IBS) is a chronic, recurrent bowel disorder with an unknown etiology, which is most likely multifactorial. Increased mucosal permeability, visceral hypersensitivity and activation status of intestinal mucosal immune cells cause changes in gastrointestinal (GI) motility, secretion and sensation observed in the course of IBS. Permanent, cumbersome symptoms, such as diarrhea, constipation and abdominal pain greatly lower quality of life of IBS patients. On this basis, according to the Rome IV criteria, different forms of IBS can be distinguished...

INTRODUCTION: Deployment of rotavirus vaccines has contributed to significant declines in diarrheal morbidity and mortality globally. Unfortunately, vaccine performance in low-middle income countries (LMICs) is generally lower than in developed countries. The cause for this has been associated with several host and maternal factors including poor water sanitation and hygiene (WASH) status, which are predominant in LMICs. More recently, environmental enteric dysfunction (EED) has specifically been hypothesized to contribute to poor vaccine uptake and response...

Dengue is an arbovirus affecting humans and spread by mosquitoes. Severe dengue follows a secondary infection with a different virus serotype. The problem is truly global as it is endemic in over 100 countries. Severe dengue can be a life-threatening because of increased vascular permeability, resulting in leakage of fluid from the intravascular compartment to the extravascular space. When major bleeding does occur, it is almost invariably combined with profound shock since this, in combination with thrombocytopenia, hypoxia, and acidosis, can lead to multiple organ failure and disseminated intravascular coagulation...

We used isobaric mass tagging (iTRAQ) and lectin affinity capture mass spectrometry (MS)-based workflows for global analyses of parotid saliva (PS) and whole saliva (WS) samples obtained from patients diagnosed with primary Sjögren's Syndrome (pSS) who were enrolled in the Sjögren's International Collaborative Clinical Alliance (SICCA) as compared with two control groups. The iTRAQ analyses revealed up- and down-regulation of numerous proteins that could be involved in the disease process (e.g., histones) or attempts to mitigate the ensuing damage (e...

Sickle cell disease (SCD) is a major global health concern. Patients with SCD experience disproportionately greater morbidity and mortality in response to influenza infection than do others. Viral infection is one contributing factor for the development of Acute Chest Syndrome (ACS), a major cause of morbidity and mortality in SCD patients. We determined whether the heightened sensitivity to influenza infection could be reproduced in the two different SCD murine models to ascertain the underlying mechanisms of increased disease severity...

OBJECTIVE: The twin pandemics of obesity and Type 2 diabetes (T2D) are a global challenge for health care systems. Changes in the environment, behavior, diet, and lifestyle during the last decades are considered the major causes. A Western diet, which is rich in saturated fat and simple sugars, may lead to changes in gut microbial composition and physiology, which have recently been linked to the development of metabolic diseases. METHODS: We will discuss evidence that demonstrates the influence of the small and large intestinal microbiota on weight regulation and the development of insulin resistance, based on literature search...

The increasing prevalence of obesity has emerged as one of the most important global public health issue. The change to the human microbiome as a result of changes in the quality and quantity of food intake over the past several decades has been implicated in the development of obesity and metabolic syndrome. We administered polysorbate-80 to mice via gavage. The researchers monitor liver noninvasively using a bioluminescence imaging. For the liver dysfunction we measure the liver enzymes and PAS stain on liver, electron microscopy liver mitochondria...

Current guidelines suggest that an early and aggressive fluid therapy is the best rescue approach to restore and preserve cardiac index, organ function and decrease the risk of multiple organ failure in shock of various origin. However, escala- tion of fluid resuscitation is a double-edged sword often associated with reperfusion, glicocalyx injury, capillary leakage, delayed weight gain and heperhydration. The body of evidences demons trates that an excessive fluid load in ICUpatient with global increased permeability syndrome, and, particularly, in ARDS and acute kidney injury can be devastating, particularly when guided with central venous pressure...

Retrospective data analysis of microcirculation in septic shock was conducted. Sepsis is characterized by a severe microvascular dysfunction that persists despite fluid resuscitation and leads to multi-organ failure even after normalization of hemodynamics in response to fluid resuscitation, vasopressors and the treatment of infection. Several clinical studies suggest that microcirculatory alterations in severe sepsis are stronger predictors of outcome than global hemodynamic variables. Microvascular dysfunction under septic shock is related to: increased capillary permeability that manifests as a breakdown of the microvascular endothelial barrier (factors which may contribute to capillary leak syndrome include endogenous proinflammatory cytokines, angiopoietin 2, vascular endothelial growth factor); arteriolar hyporesponsiveness to vasoconstrictors and vasodilators, the loss of adrenergic sensitivity and tone of smooth muscle cells lining the arterioles; loss of the anti-adhesive function of endothelial surfaces; decreased density of perfused capillaries (due to several contributing factors: decreased deformability of erythrocytes and neutrophils; activation of the clotting cascade with fibrin deposition and the formation of microthrombi; dysfunction of vascular autoregulatory mechanisms by nitric oxide; enhanced functional arteriovenous shunting of the microcirculation)...

The trisomy of human chromosome 21 (Hsa21), which causes Down syndrome (DS), is the most common viable human aneuploidy. In contrast to trisomy, the complete monosomy (M21) of Hsa21 is lethal, and only partial monosomy or mosaic monosomy of Hsa21 is seen. Both conditions lead to variable physiological abnormalities with constant intellectual disability, locomotor deficits, and altered muscle tone. To search for dosage-sensitive genes involved in DS and M21 phenotypes, we created two new mouse models: the Ts3Yah carrying a tandem duplication and the Ms3Yah carrying a deletion of the Hspa13-App interval syntenic with 21q11...

BACKGROUND: Extravascular lung water (EVLW), as measured by the thermodilution method, reflects the extent of pulmonary edema. Currently, there are no clinically effective treatments for preventing increases in pulmonary vascular permeability, a hallmark of lung pathophysiology, in patients with acute lung injury/acute respiratory distress syndrome (ALI/ARDS). In this study, we examined the contributions of hemodynamic and osmolarity factors, for which appropriate interventions are expected in critical care, to EVLW in patients with ALI/ARDS...

Ketamine is used clinically for anesthesia but is also abused as a recreational drug. Previously, it has been established that ketamine‑induced bladder interstitial cystitis is a common syndrome in ketamine‑abusing individuals. As the mechanisms underlying ketamine‑induced cystitis have yet to be revealed, the present study investigated the effect of ketamine on human urothelial cell lines and utilized a ketamine‑injected mouse model to identify ketamine‑induced changes in gene expression in mice bladders...

Dengue fever has emerged as a global public health problem in the recent decades. The clinical spectrum of the disease ranges from dengue fever to dengue hemorrhagic fever and dengue shock syndrome. The disease is characterized by increased capillary permeability, thrombocytopenia and coagulopathy. Thrombocytopenia with hemorrhagic manifestations warrants platelet transfusions. There is lack of evidence-based guidelines for transfusion support in patients with dengue fever. This contributes to inappropriate use of blood components and blood centers constantly face the challenge of inventory management during dengue outbreaks...

Secondary intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are closely related to fluid resuscitation. IAH causes major deterioration of the cardiac function by affecting preload, contractility and afterload. The aim of this review is to discuss the different interactions between IAH, ACS and resuscitation, and to explore a new hypothesis with regard to damage control resuscitation, permissive hypotension and global increased permeability syndrome. Review of the relevant literature via PubMed search...

OBJECTIVE: Lung contusion is a major risk factor for the development of acute respiratory distress syndrome. Hypoxia-inducible factor-1α is the primary transcription factor that is responsible for regulating the cellular response to changes in oxygen tension. We set to determine if hypoxia-inducible factor-1α plays a role in the pathogenesis of acute inflammatory response and injury in lung contusion. DESIGN: Nonlethal closed-chest unilateral lung contusion was induced in a hypoxia reporter mouse model and type 2 cell-specific hypoxia-inducible factor-1α conditional knockout mice...

Diarrheal diseases constitute a significant global health burden and are a major cause of childhood mortality and morbidity. Treatment of diarrheal disease has centered on the replacement of fluid and electrolyte losses using oral rehydration solutions. Although oral rehydration solutions have been highly successful, significant mortality and morbidity due to diarrheal disease remains. Secretory diarrheas, such as those caused by bacterial and viral enterotoxins, result from activation of cyclic nucleotide and/or Ca(2+) signaling pathways in intestinal epithelial cells, enterocytes, which increase the permeability of Cl(-) channels at the lumen-facing membrane...
