Fetal alcohol spectrum disorders (FASD) are caused by ethanol exposure during the pregnancy and is the leading cause of mental retardation. Ethanol exposure during the development results in the loss of neurons in the developing brain, which may underlie many neurobehavioral deficits associated with FASD. It is important to understand the mechanisms underlying ethanol-induced neuronal loss and develop appropriate therapeutic strategies. One of the potential mechanisms involves neuroimmune activation. Using a third trimester equivalent mouse model of ethanol exposure, we demonstrated that ethanol induced a wide-spread neuroapoptosis, microglial activation, and neuroinflammation in C57BL/6 mice...

Methicillin-resistant S. aureus (MRSA) has attracted more and more attention in recent years, especially in burn medical centers. Here we conducted a 5-year period study to evaluate the MRSA infection in our burn center. The staphylococcal chromosomal cassette mec (SCCmec) typing, antimicrobials susceptibility and virulence profiles were also performed among the MRSA isolates. Of the 259 S. aureus isolates, 239 (92.28%) isolates were identified as MRSA. A decreased trend of MRSA isolation rate over time was found (P = 0...

Mark G Papich
BACKGROUND: Doxycycline has been considered the first drug of choice for treating Wolbachia, a member of the Rickettsiaceae, which has a symbiotic relationship with filarial worms, including heartworms. Wolbachia, is susceptible to tetracyclines, which have been used as adjunctive treatments for heartworm disease. Treatment with doxycycline reduces Wolbachia numbers in all stages of heartworms and improves outcomes and decreased microfilaremia in dogs treated for heartworm disease. The American Heartworm Society recommends treatment with doxycycline in dogs diagnosed with heartworm disease at a dose of 10 mg/kg twice daily for 28 days...

Background: Whenever the rate of central line-associated bloodstream infections (CLABSIs) remains high even after the implementation of preventive strategies, the use of chlorhexidine/silver sulfadiazine (CSS) or minocycline/rifampin (MR)-impregnated central venous catheters (CVCs) is currently recommended. Nevertheless, the efficacy of such CVCs against Candida albicans and other emerging non-albicans spp. has been insufficiently studied. This study aims to compare the activity of CSS and MR-impregnated CVCs against the yeasts most frequently isolated from CLABSIs...

BACKGROUND: Sleep deprivation (SD) leads to cognitive impairment. Neuroinflammation could be a significant contributing factor in the same. An increase in regional brain pro-inflammatory cytokines induces cognitive deficits, however, the magnitude of the effect under SD is not apparent. It is plausible that microglia activation could be involved in the SD-induced cognitive impairment by modulation of neuronal cell proliferation, differentiation, and brain-derived neuronal factor (BDNF) level...

Reducing early nonbacterial inflammation induced by implanted materials and infection resulting from bacterial contamination around the implant-abutment interface could greatly accelerate implant osseointegration and reduce implant failure, which would be of clinical significance. In this study, we developed a facile and versatile strategy for the construction of anti-inflammatory and antibacterial surfaces on implants, such as orthopedic/dental implants. Briefly, the surfaces of polystyrene (PS) culture plates were first coated with polydopamine and then decorated with dexamethasone plus minocycline-loaded liposomes (Dex/Mino liposomes), which was confirmed by contact angle goniometry, X-ray photoelectron spectroscopy, and fluorescence microscopy...

Neuropathic pain is a common and refractory chronic pain that affects millions of people worldwide. Its underlying mechanisms are still unclear, but they may involve long noncoding RNAs (lncRNAs), which play crucial roles in a variety of biological functions, including nociception. We used microarrays to investigate the possible interactions between lncRNAs and neuropathic pain and identified 22,213 lncRNAs and 19,528 mRNAs in the spinal cord in a mouse model of spared nerve injury (SNI)-induced neuropathic pain...

Purpose: Diarrhea and oral mucositis induced by afatinib can cause devastating quality of life issues for patients undergoing afatinib treatment. Several studies have shown that hangeshashin-to (TJ-14) might be useful for chemotherapy-induced diarrhea and oral mucositis. In this study, we investigated the prophylactic effects of TJ-14 for afatinib-induced diarrhea and oral mucositis and minocycline for afatinib-induced skin rash. Patients and methods: First- and second-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors have become the standard first-line treatment in patients with EGFR-mutated non-small cell lung cancer...

BACKGROUND: The at-risk mental state (ARMS) describes individuals at high risk of developing schizophrenia or psychosis. The use of antipsychotics in this population is not supported, because most individuals with ARMS are unlikely to develop psychosis. Anti-inflammatory treatments and polyunsaturated fatty acids (PUFAs) may have some beneficial effects in the treatment of ARMS. There have been no controlled clinical trials in which researchers have investigated the use of minocycline for ARMS and no trials involving PUFAs in combination with other proposed treatments...

OBJECTIVE: Aberrant neutrophil extracellular trap (NET) formation has been implicated as a mechanism to induce auto-reactivity in at-risk individuals. The study objective was to assess whether medications implicated in cases of drug-induced autoimmunity (hydralazine and procainamide) and medications less commonly associated with drug-induced autoimmunity (minocycline and clozapine) induce NET formation and/or prevent NET degradation. METHODS: Human neutrophils were incubated with the drugs of interest and resultant NET formation was quantified by fluorescent microscopy...

To the best of our knowledge, no studies have yet examined the electrostatic interaction of polyelectrolytes with electrolyte drugs for the treatment of rheumatoid arthritis (RA). Here, an injectable, electrostatically interacting drug depot is described. We prepared methoxy polyethylene glycol-b-poly(ε-caprolactone)-ran-poly(l-lactic acid) (MC) diblock copolymers with a carboxylic acid group (MC-C) at the pendant position. MC-C was polyelectrolytes that exhibited negative zeta potentials. Sulfasalazine [Sul(-)] and minocycline [Min(+)], electrolyte RA drugs, exhibited negative and positive zeta potentials, respectively...

Tolerogenic dendritic cells (tDCs) represent a promising tool for cellular therapy against autoimmune diseases, allergies, and transplantation rejection. Numerous pharmacological agents are known to induce tDC generation. Minocycline, which has long been used as a broad-spectrum antibiotic, was recently shown to significantly increase the generation of DCs with regulatory properties. Here, we examined the effect of the combination of minocycline with dexamethasone, rapamycin, vitamin D3, and interleukin (IL)-10, which are all known inducers of tDC generation...

Impairment of vision or blindness always occurs in the progress of corneal neovascularization (CNV). CNV may cause corneal graft rejection at corneal transplant status. Thus, intervention of CNV is of concern to clinical treatment. Given minocycline was reported with inhibiting effect on CNV, our study was focused on specific effect of minocycline on CNV after corneal alkaline burn. Seventy-five male Sprague Dawley rats were randomly assigned into three groups with an equal number (25). Sodium hydroxide (NaOH) solution was used to establish corneal alkaline burn model...

Sepsis impairs learning and memory function, yet marked interindividual variability exists in the degree to which sepsis compromises learning and memory function. Thus, testing resilience versus susceptibility to systemic inflammation induced-memory impairment and the underlying mechanism is needed. In the present study, we firstly used lipopolysaccharide (LPS) to induce memory impairment, and then evaluated cognitive function on days 4-7 after the first LPS challenge. Subjects' scores on both behavioral measures were subjected to a hierarchical cluster analysis, identifying two clusters that differed notably on the Y-maze and fear conditioning tests...
