The kinin B and B receptors and TNFR1/p55 axis on neuropathic pain in the mouse brachial plexus.

Tumour necrosis factor (TNF) and kinins have been associated with neuropathic pain-like behaviour in numerous animal models. However, the way that they interact to cause neuron sensitisation remains unclear. This study assessed the interaction of kinin receptors and TNF receptor TNFR1/p55 in mechanical hypersensitivity induced by an intraneural (i.

Biological and Toxicological Evaluation of N-(4methyl-phenyl)-4-methylphthalimide on Bone Cancer in Mice.

Background: It was recently demonstrated that the phthalimide N-(4-methyl-phenyl)-4- methylphthalimide (MPMPH-1) has important effects against acute and chronic pain in mice, with a mechanism of action correlated to adenylyl cyclase inhibition. Furthermore, it was also demonstrated that phthalimide derivatives presented antiproliferative and anti-tumor effects. Considering the literature data, the present study evaluated the effects of MPMPH-1 on breast cancer bone metastasis and correlated painful symptom, and provided additional toxicological information about the compound and its possible metabolites.

Understanding Breast Cancer Knowledge and Barriers to Treatment Adherence: A Qualitative Study Among Breast Cancer Survivors.

Disparities in breast cancer treatment receipt are common and multifactorial. Data are limited on how knowledge about one's breast cancer and understanding treatment rationales may impact treatment completion. In this qualitative analysis, we explored barriers to care with a focus on knowledge.

Neuropharmacological and acute toxicological evaluation of ethanolic extract of Allamanda cathartica L. flowers and plumieride.

Psychiatric diseases affect more than 350 million people all over the world, and medicinal plants have been considered the basis for pharmacological research. The study investigates the anticonvulsant and antidepressant-like activities and acute toxicological effects of ethanolic extract of Allamanda cathartica flowers, and plumieride. The extract was analyzed by HPLC and plumieride was isolated.

Differential requirements for the canonical NF-κB transcription factors c-REL and RELA during the generation and activation of mature B cells.

Signaling through the canonical nuclear factor-κB (NF-κB) pathway is critical for the generation and maintenance of mature B cells and for antigen-dependent B-cell activation. c-REL (rel) and RELA (rela) are the downstream transcriptional activators of the canonical NF-κB pathway. Studies of B cells derived from constitutional rel knockout mice and chimeric mice repopulated with rela fetal liver cells provided evidence that the subunits can have distinct roles during B-cell development.

Nanoemulsion as a carrier to improve the topical anti-inflammatory activity of stem bark extract of .

The aim of this study was to develop nanoemulsion containing soft extract of stem bark of to improve the topical delivery and anti-inflammatory activity. The extract of stem bark was incorporated into the oily phase of the nanoemulsion by the method of phase inversion at low energy. The developed nanoemulsion had an average droplet size of 47.

Transcription factors of the alternative NF-κB pathway are required for germinal center B-cell development.

The NF-κB signaling cascade relays external signals essential for B-cell growth and survival. This cascade is frequently hijacked by cancers that arise from the malignant transformation of germinal center (GC) B cells, underscoring the importance of deciphering the function of NF-κB in these cells. The NF-κB signaling cascade is comprised of two branches, the canonical and alternative NF-κB pathways, mediated by distinct transcription factors.

Impairment of Mature B Cell Maintenance upon Combined Deletion of the Alternative NF-κB Transcription Factors RELB and NF-κB2 in B Cells.

BAFF is critical for the survival and maturation of mature B cells. BAFF, via BAFFR, activates multiple signaling pathways in B cells, including the alternative NF-κB pathway. The transcription factors RELB and NF-κB2 (p100/p52) are the downstream mediators of the alternative pathway; however, the B cell-intrinsic functions of these NF-κB subunits have not been studied in vivo using conditional alleles, either individually or in combination.

Assessing intern handover processes.

Background: New standards for resident work hours set in 2011 changed the landscape of patient care in teaching hospitals, and resulted in new challenges for US residency training programmes to overcome. One such challenge was a dramatic increase in the number of patient handovers performed by residents. As a result, there is a renewed focus for clinical teachers to develop educational strategies to optimise the patient handover process and improve the quality of patient care and safety.

Germinal center B cell maintenance and differentiation are controlled by distinct NF-κB transcription factor subunits.

Germinal centers (GCs) are the sites where memory B cells and plasma cells producing high-affinity antibodies are generated during T cell-dependent immune responses. The molecular control of GC B cell maintenance and differentiation remains incompletely understood. Activation of the NF-κB signaling pathway has been implicated; however, the distinct roles of the individual NF-κB transcription factor subunits are unknown.

The antihypersensitive and antiinflammatory activities of a benzofuranone derivative in different experimental models in mice: the importance of the protein kinase C pathway.

Background: Benzofuranone (BF1) was synthesized and its effects evaluated on mechanical hypersensitivity and paw edema models induced by different agents and on neuropathic pain induced by partial ligation of the sciatic nerve. An attempt was also made to elucidate the mechanism of action.

Methods: Swiss mice were used for the tests.

IRF4 controls the positioning of mature B cells in the lymphoid microenvironments by regulating NOTCH2 expression and activity.

The transcription factor interferon regulatory factor-4 (IRF4) is expressed in B cells at most developmental stages. In antigen-activated B cells, IRF4 controls germinal center formation, class-switch recombination, and the generation of plasma cells. Here we describe a novel function for IRF4 in the homeostasis of mature B cells.

Variability in hand hygiene practices among internal medicine interns.

Hand hygiene compliance remains suboptimal among physicians despite quality improvement efforts. We observed hand hygiene compliance among 29 medicine interns at 2 large academic institutions. Overall compliance was 75%.

In the wake of the 2003 and 2011 duty hours regulations, how do internal medicine interns spend their time?

Background: The 2003 and 2011 Accreditation Council for Graduate Medical Education (ACGME) common program requirements compress busy inpatient schedules and increase intern supervision. At the same time, interns wrestle with the effects of electronic medical record systems, including documentation needs and availability of an ever-increasing amount of stored patient data.

Objective: In light of these changes, we conducted a time motion study to determine how internal medicine interns spend their time in the hospital.

From popular use to pharmacological validation: a study of the anti-inflammatory, anti-nociceptive and healing effects of Chenopodium ambrosioides extract.

Unlabelled: ETHNO-PHARMACOLOGICAL RELEVANCE: Chenopodium ambrosioides (Amarantaceae) is an annual or perennial plant popularly known as 'erva de Santa Maria', 'mastruço' and 'erva-do-formigueiro'. This herb is used in folk medicine in the form of teas, poultices and infusions for inflammatory problems, contusions and lung infections, and as an anthelmintic and anti-fungal.

Aim Of The Study: The aim of the present study was to further the understanding of the anti-nociceptive, anti-inflammatory and wound healing effects of ethanol extract (EE) obtained from the leaves and stems of Chenopodium ambrosioides in animal models of acute pain, inflammation and wound healing, thus supporting its medicinal use for the treatment of pain and inflammatory conditions

Materials And Methods: The anti-nociceptive activity of EE (150-500 mg/kg) was evaluated using the nociception induced by formalin (2.

Retinal pigment epithelial cells use a MerTK-dependent mechanism to limit the phagocytic particle binding activity of αvβ5 integrin.

Background Information: αvβ5 integrin and Mer tyrosine kinase (MerTK) receptors reside at the apical surface of the retinal pigment epithelium (RPE) in the eye to promote the diurnal, synchronised phagocytosis of shed photoreceptor outer segment fragments (POS) that is critical for vision. Phagocytosis assays studying RPE cells in culture have defined roles for αvβ5 in POS surface binding and for MerTK in engulfment of bound POS. Both receptors have thus far only been studied separately.

Plant derived alkaloid (-)-cassine induces anti-inflammatory and anti-hyperalgesics effects in both acute and chronic inflammatory and neuropathic pain models.

Natural products have been revealed as relevant sources of therapeutic agents including those for the management of pain states. In this study, the anti-nociceptive and anti-inflammatory effects of (-)-cassine, isolated from Senna spectabilis were evaluated using pharmacological, behavioural and biochemical approaches. Oral treatment with (-)-cassine (3-30 mg/kg) reduced carrageenan-induced mechanical and thermal nociception associated with the suppression of myeloperoxidase activity in the mouse paw.

Background: Many studies have shown the antinociceptive effects of cannabinoid (CB) agonists in different models of pain. Herein, we have investigated their relevance in neuropathic pain induced by brachial plexus avulsion (BPA) in mice.

Methodology/principal Findings: Mice underwent BPA or sham surgery.

Involvement of phosphoinositide 3-kinase gamma in the neuro-inflammatory response and cognitive impairments induced by beta-amyloid 1-40 peptide in mice.

Alzheimer disease (AD) is the most common form of dementia in the elderly, and the neuro-pathological hallmarks of AD include neurofibrillary tangles (NFT), and deposition of beta-amyloid (Abeta) in extracellular plaques. In addition, chronic inflammation due to recruitment of activated glial cells to amyloid plaques are an invariant component in AD, and several studies have reported that the use of non-steroidal anti-inflammatory drugs (NSAIDs) may provide a measure of protection against AD. In this report we have investigated whether phosphoinositide 3-kinase gamma (PI3Kgamma), which is important in inflammatory cell migration, plays a critical role in the neuro-inflammation, synaptic dysfunction, and cognitive deficits induced by intracerebroventricular injection of Abeta(1-40) in mice.
