Frutalin is a galactose-binding lectin that has an irreversible cytotoxic effect on HeLa cervical cancer cells, by inducing apoptosis and inhibiting cell proliferation. It was previously shown that after in vitro incubation, frutalin is internalized into HeLa cells nucleus, which indicates that frutalin apoptosis-inducing activity might be linked with its nuclear localization. Considering that drugs commonly used for cancer treatment have a deleterious effect on germ cells, the aim of this study was to evaluate the effect of frutalin on the activation, survival, ultrastructure and gene expression in follicles cultured within ovarian tissue...

The receptor for advanced glycation endproducts (RAGE) is a key mediator of neuroinflammation following cerebral ischemia. Nitric oxide (NO) plays a dualistic role in cerebral ischemia, depending on whether it originates from neuronal, inducible or endothelial synthase. Although a dynamic interplay between RAGE and NO pathways exists, its relevance in ischemic stroke has not been investigated. The aim of this study is to evaluate the effect of the NO synthase (NOS) inhibition on RAGE expression in rats subjected to transient middle cerebral artery occlusion (tMCAo)...

Rheumatoid arthritis (RA) is one of the commonest rheumatological diseases. Renal involvement is not common but can occur as a result of chronic inflammation as part of disease process or drug toxicity. Thrombotic microangiopathy (TMA) is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and organ failure of variable severity. Only a few cases of TMA in patients with RA were reported to date. We describe a 45-year-old female patient with RA who presented with oliguria and edema. Renal biopsy showed TMA with patchy cortical necrosis...

The transfer of a contralateral healthy seventh cervical spinal nerve root (cC7) to the recipient nerve in the injured side is considered a reliable and effective procedure for restoration of the physiological functions of an injured hand after brachial plexus root avulsion injury (BPAI). Growing evidence shows that the transhemispheric cortical reorganization is induced after cC7 nerve transfer surgery. However, little is known about the underlying molecular mechanism. Proinflammatory cytokines reportedly play an important role in the neural plasticity...

CSP-1103 (formerly CHF5074) has been shown to reverse memory impairment and reduce amyloid plaque as well as inflammatory microglia activation in preclinical models of Alzheimer's disease. Moreover, it was found to improve cognition and reduce brain inflammation in patients with mild cognitive impairment. Recent evidence suggests that CSP-1103 acts through a single molecular target, the amyloid precursor protein intracellular domain (AICD), a transcriptional regulator implicated in inflammation and apoptosis...

Traumatic brain injury (TBI) is the predominant cause of mortality in young adults and children living in China. TBI induces inflammatory responses; in addition, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6 are important pro-inflammatory cytokines. Considering the observation that Hsp-70 overexpression can exert neuroprotection, identifying a drug that is able to induce the upregulation of Hsp70 has the potential to be a promising therapy for the treatment of neurological diseases. Thus, the present study assessed the clinical effectiveness of an anticancer drug and Hsp70 activator, 17-allylamino-demethoxygeldanamycin (17-AAG), to evaluate its potential as a treatment for patients with TBI...

The proinflammatory cytokine tumour necrosis factor-alpha (TNFα) has long been characterized for its role in the innate immune system, but more recently has been found to have a distinct role in the nervous system that does not overlap with other proinflammatory cytokines. Through regulation of neuronal glutamate and GABA receptor trafficking, TNF mediates a homeostatic form of synaptic plasticity, but plays no direct role in Hebbian forms of plasticity. As yet, there is no evidence to suggest that this adaptive plasticity plays a significant role in normal development, but it does maintain neuronal circuit function in the face of several types of disruption...

BACKGROUND: In addition to neurons, all components of the neurovascular unit (NVU), such as glial, endothelial, and basal membranes, are destroyed during traumatic brain injury (TBI). Previous studies have shown that excessive stimulation of calpain is crucial for cerebral injury after traumatic insult. The objective of this study was to investigate whether calpain activation participated in NVU disruption and edema formation in a mouse model of controlled cortical impact (CCI). METHODS: One hundred and eight mice were divided into three groups: the sham group, the control group, and the MDL28170 group...

Depression is a common disease that afflicts one in six people at some points in life. Numerous hypotheses have been raised in past years, but the exact mechanism that can be used to explain the development of depression remains obscure. Recently, more and more attentions are being focused on neuroinflammation and oxidative stress in depression. WY-14643, an agonist of peroxisome proliferator-activated receptor-α (PPAR-α), has been reported to inhibit neuroinflammation and oxidative stress, and one of our previous studies have showed that WY-14643 possesses antidepressive activities...

Cryoprobes create localized cell destruction through freezing. Bone is resistant to temperature flow but is susceptible to freezing necrosis at warmer temperatures than tumor cells. Few studies have determined the thermal conductivity of human bone. No studies have examined conductivity as related to density. The study goal was to examine thermal conductivity in human bone while comparing differences between cancellous and cortical bone. An additional goal was to establish a relationship between bone density and thermal conductivity...

Chondromyxoid fibroma-like osteosarcoma (CMF-OS) is a low-grade osteosarcoma, often misdiagnosed on initial biopsy as a benign lesion, with five cases previously described. We report a 13-year-old male with an intramedullary lytic CMF-OS of the right tibial proximal metaphysis with cortical destruction and soft tissue extension. Diagnosis was based on malignant new bone formation, increased mitotic figures, lamellar bone permeation with bony destruction, and correlation with imaging studies. There were no metastasis at presentation and the tumor showed good response to standard chemotherapy with >95% necrosis...
