Context • Balneotherapy is one of the most commonly used nonpharmacological interventions for osteoarthritis (OA), but its mechanism of action in relieving pain and stiffness and in improving physical function is not well understood. Studies have found that therapy provokes a series of neuroendocrinal reactions with anti-inflammatory and analgesic effects. Sphingosine-1-phosphate (S1P), a bioactive lipid, has been implicated as an important mediator in the maintenance of physiological processes (eg, vascular barrier integrity) and in pathophysiologic processes such as inflammatory conditions...

Henoch-Schönlein purpura (HSP) is systemic vasculitis disease with various clinical manifestations. Gastrointestinal symptoms in patients with HSP are usually common, with an incidence rate of 62-90%. Most of these gastrointestinal symptoms occur after typical skin purpura, which is a very important clinical evidence for making a diagnosis of HSP. It is difficult to diagnose HSP without skin rash. About 25% of patients may experience gastrointestinal symptoms as their first symptoms. Herein, we report a case of ileo-colic intussusception associated with HSP in a 5-years-old girl presented with diffuse abdominal distension...

The ability to interface microfluidic devices with native complex biological architectures, such as whole organs, has the potential to shift the paradigm for the study and analysis of biological tissue. Here, we show 3D printing can be used to fabricate bio-inspired conformal microfluidic devices that directly interface with the surface of whole organs. Structured-light scanning techniques enabled the 3D topographical matching of microfluidic device geometry to porcine kidney anatomy. Our studies show molecular species are spontaneously transferred from the organ cortex to the conformal microfluidic device in the presence of fluid flow through the organ-conforming microchannel...

Cancer cells are continuously challenged by adverse environmental factors including hypoxia, metabolite restriction, and immune reactions, and must adopt diverse strategies to survive. Heat shock protein (Hsp) 70 plays a central role in protection against stress-induced cell death by maintaining protein homeostasis and interfering with the process of programmed cell death. Recent findings have suggested that Hsp70 acetylation is a key regulatory modification required for its chaperone activity, but its relevance in the process of programmed cell death and the underlying mechanisms involved are not well understood...

Toxoplasma gondii is an obligate intracellular apicomplexan parasite that infects almost all warm-blooded vertebrates. Heat shock proteins (HSP) regulate key signal transduction events in many organisms, and heat shock protein 90 (Hsp90) plays an important role in growth, development, and virulence in several parasitic protozoa. Here, we discovered increased transcription of the Hsp90 gene under conditions for bradyzoite differentiation, i.e. alkaline and heat shock conditions in vitro, suggesting that Hsp90 may be connected with bradyzoite development in T...

Sunitinib malate (sunitinib) is an orally available, multitargeted tyrosine kinase inhibitor with antitumor and antiangiogenic activities. Although sunitinib is effective for the treatment of patients with gastrointestinal stromal tumor, advanced renal cell carcinoma, or pancreatic neuroendocrine tumor, adverse cardiac events associated with sunitinib administration have been reported. Here, we examined the effect of geldanamycin, an inhibitor of heat shock protein (Hsp) 90, on sunitinib-induced cytotoxicity in cardiomyocytes...

Xin Xu, Lucas Pozzo-Miller
Rett syndrome is a neurodevelopmental disorder caused by loss-of-function mutations in MECP2, the gene encoding the transcriptional regulator methyl-CpG-binding protein 2 (MeCP2). Deletion of Mecp2 in mice results in an imbalance of synaptic excitation and inhibition in hippocampal pyramidal neurons, which affects "Hebbian" long-term synaptic plasticity. Since the excitatory/inhibitory (E/I) balance is maintained by homeostatic mechanisms, we examined the role of MeCP2 in homeostatic synaptic plasticity (HSP) at excitatory synapses...

Piwi-interacting RNAs (piRNAs), a novel class of small non-coding RNA, were first discovered in germline cells and are thought to silence transposons in spermatogenesis. Recently, piRNAs have also been identified in somatic tissues, and aberrant expression of piRNAs in tumor tissues may be implicated in carcinogenesis. However, the function of piR-823 in colorectal cancer (CRC) remains unclear. Here, we first found that piR-823 was significantly up-regulated in CRC tissues compared with its expression in the adjacent tissues...

AIMS: Heat shock proteins (HSPs) are a group of molecules induced by a variety of environmental and pathophysiologic stresses, including cancer. HSPs are implicated in the regulation of apoptosis and immunity in neoplasm. Transcription factor heat shock factor1 (HSF1) acts as the master regulator to control HSP expression, and therefore is involved in tumorigenesis. The purpose of this study was to evaluate the expression and clinicopathologic relevance of HSPs and HSF1 in clear cell renal cell carcinoma (ccRCC)...

The traditional herbal medicine, Hochu-ekki-to, has been shown to have preventive effects on viral infection and stress. This study aimed to evaluate the clinical effects of Hochu-ekki-to on two stress-related rat models of polycystic ovarian syndrome. Female Sprague-Dawley rats were divided into control and treatment groups, the latter of which were subjected to stress induced by exposure to adrenocorticotropic hormone (ACTH) or cold temperatures. After these stress inductions, rats were orally treated with dissolved Hochu-ekki-to once per day for 7 days...

BACKGROUND: Oxidative stress and inflammation exacerbate tissue damage in the brain after ischemic stroke. Dimethyl-fumarate (DMF) and its metabolite monomethyl-fumarate (MMF) are known to stimulate anti-oxidant pathways and modulate inflammatory responses. Considering these dual effects of fumarates, we examined the effect of MMF treatment after ischemic stroke in mice. METHODS: Permanent middle cerebral artery occlusion (pMCAO) was performed using adult, male C57BL/6 mice...

Heat-shock proteins (HSPs) are highly expressed when organisms are exposed to thermal stresses. The HSPs are considered to play significant roles in thermal adaptation because they function as molecular chaperones facilitating proper protein synthesis. The expression of HSPs under field conditions, however, has not been evaluated much, and their importance, based on the ecological contexts in nature, is still unclear. We investigated this aspect in the larvae and adults of the flesh fly, Sarcophaga similis...

Henoch-Schönlein purpura (HSP) is the most common form of systemic small-vessel vasculitis in children, and HSP nephritis (HSPN) is a major complication of HSP and is the primary cause of morbidity and mortality. Previous studies have suggested that inducible nitric oxide synthase (iNOS) may play an important role in the pathogenesis of HSP. In this study, we performed a detailed analysis to investigate the potential association between iNOS polymorphisms and the risk of HSP and the tendency for children with HSP to develop HSPN in a Chinese Han population...

To investigate whether red blood cell distribution width (RDW) is a marker of the risk of Henoch-Schonlein purpura (HSP) nephritis (HSPN), a total of 669 HSP patients and 168 healthy controls were included in this retrospective study. Two hundred fifty-six (38.3%) of the patients had kidney involvement. Compared with the HSP group, RDW was significantly higher in the HSPN group (P < .001). Binary logistic regression identified that HSPN was independently associated with age, RDW, platelet, and total cholesterol (odds ratio = 1...

Aronia melanocarpa (Michx.) Ell. belongs to the Rosaceae family. The purpose of this study is to explore the gastroprotective effect of the Aronia melanocarpa hydro-alcoholic extract (AMHAE) against ethanol-induced gastric ulcer in a rat model. Different concentrations (50, 100, and 200 mg/kg) of AMHAE, or 30 mg/kg of omeprazole, significantly inhibited the gastric injury formation. The ethanol-induced ulcer group showed significant increases of malondialdehyde (MDA), myeloperoxidase (MPO), tumor necrosis factor (TNF)-α, nuclear factor-kappaB p65 (NF-κB p65), and monocyte chemoattractant protein (MCP)-1, and decreased activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-px), and interleukin (IL)-4...

About 1000 species of bacteria are present in the human intestine. Some Gram-negative bacteria such as Escherichia coli or Salmonella spp. among intestinal bacteria have lipopolysaccharide (LPS), which might induce inflammation of human intestines. Actually, LPS, especially its lipid A constituent, is toxic. Small amounts of LPS in bacteria cause inflammation of mucosa and other tissues in humans. Such bacteria may be regulated by beneficial lactic acid bacteria to maintain human health. Many lactic acid bacteria show cancer prevention activity and anti-inflammatory activity in intestines...
