Therapeutic ultrasound (TUS) has been demonstrated to improve endothelial nitric oxide synthase (eNOS) activity, which played a crucial role in the regulation of angiogenesis. Diabetes Mellitus (DM) impairs eNOS activity. We tested the hypothesis that DM may retard unilateral hindlimb ischemia-induced angiogenesis by inhibiting eNOS in high-fat diet (HFD)/streptozocin (STZ) induced diabetic mice, and that TUS may reverse DM-related impairment of angiogenesis. C57BL/6 mice were allocated to four groups: (A) mice were fed standard diet (control); (B) mice were fed standard diet and treated with TUS (control+TUS); (C) type-2 DM mice were induced by HFD/STZ (diabetic); and (D) type-2 DM mice and treated with TUS (dabetic+TUS)...

While a plethora of studies support a therapeutic benefit of Nrf2 activation and ROS inhibition in diabetic nephropathy (dNP), the Nrf2 activator bardoxolone failed in clinical studies in type 2 diabetic patients due to cardiovascular side effects. Hence, alternative approaches to target Nrf2 are required. Intriguingly, the tetracycline antibiotic minocycline, which has been in clinical use for decades, has been shown to convey anti-inflammatory effects in diabetic patients and nephroprotection in rodent models of dNP...

: Essentials The role of protein C (PC) activation in experimental autoimmune encephalitis (EAE) is unknown. PC activation is required for mitochondrial function in the central nervous system. Impaired PC activation aggravates EAE, which can be compensated for by soluble thrombomodulin. Protection of myelin by activated PC or solulin is partially independent of immune-modulation. SUMMARY: Background Studies with human samples and in rodents established a function of coagulation proteases in neuro-inflammatory demyelinating diseases (e...

Preeclampsia (PE) is a placenta-induced inflammatory disease associated with maternal and fetal morbidity and mortality. The mechanisms underlying PE remain enigmatic and delivery of the placenta is the only known remedy. PE is associated with coagulation and platelet activation and increased extracellular vesicle (EV) formation. However, thrombotic occlusion of the placental vascular bed is rarely observed and the mechanistic relevance of EV and platelet activation remains unknown. Here we show that EVs induce a thromboinflammatory response specifically in the placenta...

Glomerular apoptosis may contribute to diabetic nephropathy (dNP), but the pathophysiologic relevance of this process remains obscure. Here, we administered two partially disjunct polycaspase inhibitors in 8-week-old diabetic (db/db) mice: M-920 (inhibiting caspase-1, -3, -4, -5, -6, -7, and -8) and CIX (inhibiting caspase-3, -6, -7, -8, and -10). Notably, despite reduction in glomerular cell death and caspase-3 activity by both inhibitors, only M-920 ameliorated dNP. Nephroprotection by M-920 was associated with reduced renal caspase-1 and inflammasome activity...

BACKGROUND: Depression and anxiety have been found to be predictors of poor health outcomes in diabetes, but mechanisms are still unclear. AIMS: To examine whether symptoms of anxiety and depression were associated with timing of initiating insulin therapy. METHODS: A cohort study of insulin-naive particpants with type 2 dabetes completed the Hospital Anxiey and Depression Scale, HADS-A (n = 731) and/or the HADS-D (n = 768) in the communy-based Nord-Trøndelag Health Study (1995-1997)...

Ischemia-reperfusion injury (IRI) is the leading cause of ARF. A pathophysiologic role of the coagulation system in renal IRI has been established, but the functional relevance of thrombomodulin (TM)-dependent activated protein C (aPC) generation and the intracellular targets of aPC remain undefined. Here, we investigated the role of TM-dependent aPC generation and therapeutic aPC application in a murine renal IRI model and in an in vitro hypoxia and reoxygenation (HR) model using proximal tubular cells. In renal IRI, endogenous aPC levels were reduced...

Diabetic nephropathy is a growing health concern with characteristic sterile inflammation. As the underlying mechanisms of this inflammation remain poorly defined, specific therapies targeting sterile inflammation in diabetic nephropathy are lacking. Intriguingly, an association of diabetic nephropathy with inflammasome activation has recently been shown, but the pathophysiological relevance of this finding remains unknown. Within glomeruli, inflammasome activation was detected in endothelial cells and podocytes in diabetic humans and mice and in glucose-stressed glomerular endothelial cells and podocytes in vitro...

BACKGROUND/AIM: In a rat model, lithium treatment is associated with polyuria and severe downregulation of aquaporin-2 (AQP2) protein in the inner medulla (IM) or in the whole kidney. However, it is not known (1) to what extent this downregulation occurs at the mRNA level; (2) whether the main sodium transporter of the nephron, Na,K-ATPase, is regulated in parallel at the mRNA level, and (3) whether lithium treatment induces zonal or segmental differences in AQP2 and Na,K-ATPase mRNA levels...

The acute abdomen in childhood is in most cases caused by an acute appendicitis and rarely it is secondary to other diseases. It is for that reason, that we present two cases extremely rare of acute abdomen: the first one was an abdominal Actinomycosis secondary to acute appendicitis that looked like a tumor and the second that was an acute omentitis due to pinworms.
