Time dependent inhibition (TDI) may confound drug interaction predictions. Recently, models were generated for an array of TDI kinetic schemes using numerical analysis of microsomal assays. Additionally, a distinct terminal inactivation step was identified for certain mechanism based inhibitors (MBI) following reversible metabolite intermediate complex (MIC) formation. Longer hepatocyte incubations potentially allow analysis of slow TDI and terminal inactivation. In the experiments presented here, we compared the quality of TDI parameterization by numerical analysis between hepatocyte and microsomal data...

Nucleic acids based adjuvants recognized by Toll-like receptors (TLR) are potent immune system stimulants that can augment the anti-tumor immune responses in an antigen-specific manner. However, their clinical uses as vaccine adjuvants are limited primarily due to lack of accumulation in the lymph nodes, the anatomic sites where the immune responses are initiated. Here, we showed that chemical conjugation of type B CpG DNA, a TLR9 agonist to dextran polymer dramatically enhanced CpG's lymph node accumulation in mice...

BACKGROUND: Since the time when drugs began to be used, it became evident that they could produce a therapeutic effect, but also a clinical condition of toxicity or no effect at all on humans, despite using the same doses in different patients. Such untoward effects were termed "drug idiosyncrasy" and also "idiosyncratic drug effects", but the factors producing such diverse responses were never taken into account. MATERIALS AND METHODS: Ruta chalepensis L. (fringed rue) is an herbaceous plant of the Rutaceae family used in traditional medicine due to its properties, such as its analgesic and antipyretic effects...

The low-dose dexamethasone suppression test (DST) is one of the commonly used initial tests for endogenous Cushing's syndrome (CS). However, there are two loading dose regimens (0.5-mg and 1-mg), which may cause some confusion in daily practice in Japan; furthermore, there are no reports regarding whether 0.5-mg DST is a better loading dose for detecting adrenal subclinical CS (SCS) based on the plasma dexamethasone (DEX) levels. Therefore, the aims of this study were (a) to develop a novel assay to measure DEX by using liquid chromatography tandem-mass spectrometry (LC-MS/MS) and (b) to compare between the 0...

Daratumumab plus pomalidomide/dexamethasone (pom-dex) was evaluated in patients with relapsed/refractory multiple myeloma with ≥2 prior lines of therapy, and who were refractory to their last treatment. Patients received daratumumab 16 mg/kg at the recommended dosing schedule, pomalidomide 4 mg daily for 21 days of each 28-day cycle, and dexamethasone 40 mg weekly. Safety was the primary endpoint. Overall response rate (ORR) and minimal residual disease (MRD) by next-generation sequencing were secondary endpoints...

Variation in the reactivity of the endocrine stress axis is thought to underlie aspects of persistent individual differences in behavior (i.e. animal personality). Previous studies, however, have focused largely on estimating baseline or peak levels of glucocorticoids (CORT), often in captive animals. In contrast, the temporal dynamics of the HPA axis-how quickly it turns on and off, for example-may better indicate how an individual copes with stressors. Moreover, these HPA components might be correlated, thereby representing endocrine suites...

Exposure to stress is known to cause hepatic iron dysregulation, but the relationship between prolonged stress and liver iron metabolism is not yet fully understood. Thirty 13-week-old female Sprague-Dawley rats were randomly divided into two groups, as follows: the control group (saline-injection) and the dexamethasone group (Dexamethasone (Dex)-injection 0.1 mg/kg/day). After the 21-day stress trial, the results showed that chronic Dex administration not only impaired serum corticosterone (p = 0.00) and interleukin-6 (IL-6) (p = 0...

Postoperative lymphedema is considered irreversible once it has developed, and significantly lowers the patient's quality of life. However, lymphatic function has recently been clarified, and it is possible that lymphedema can be cured if early treatment is started. This two-arm randomized clinical trial (UMIN000026124) will prospectively evaluate 24 patients with early-stage breast cancer-related lymphedema at the Nagoya University Hospital and Aichi Cancer Center Hospital. The eligibility criteria will be patients who are diagnosed with stage 0-1 breast cancer-related lymphedema, as defined by the International Society of Lymphology, within 12 weeks after breast cancer surgery...

Cushing syndrome (CS) is caused by chronic exposure to excess glucocorticoids. Early recognition and treatment of hypercortisolemia can lead to decreased morbidity and mortality. The diagnosis of CS and thereafter, establishing the cause can often be difficult, especially in patients with mild and cyclic hypercortisolism. Surgical excision of the cause of excess glucocorticoids is the optimal treatment for CS. Medical therapy (steroidogenesis inhibitors, medications that decrease adrenocorticotropic hormone [ACTH] levels or glucocorticoid antagonists) and pituitary radiotherapy may be needed as adjunctive treatment modalities in patients with residual, recurrent or metastatic disease, in preparation for surgery, or when surgery is contraindicated...

Microfluidic methods are frequently used to produce cell-laden microgels for various biomedical purposes. Such microfluidic methods generally employ oil-water systems. The poor distribution of crosslinking reagents in the oil phase limits the available gelation strategies. Extracting the microgel from the oil-phase also reduces its production efficiency. In this study, an aqueous two-phase system (ATPS) involving dextran (DEX) and polyethylene glycol (PEG) was used to prepare cell-laden microgel. This avoided the problems associated with an oil phase...

BACKGROUND: Severe inflammation plays a vital role in the pathogenesis of meconium aspiration syndrome (MAS). Intratracheal (IT) instillation of corticosteroids may be beneficial for MAS in optimizing local effect and reducing systemic adverse effects, but the optimum dosing course remains open to question. METHODS: Thirty meconium-injured newborn piglets were enrolled into six study groups. The first four groups consisted of the IT instillation of 0.25/0.5 mg/kg using either one (IT-B251/IT-B501) or two (IT-B252/IT-B502) doses of budesonide, while the other two groups were the intravenous (IV) dexamethasone (0...

Neuroinflammation mediated by NLRP-1 inflammasome plays an important role in the pathogenesis of neurodegeneration diseases such as Alzheimer's disease (AD). Chronic glucocorticoids (GCs) exposure has deleterious effect on the structure and function of neurons and was found to be correlated with development and progression of AD. We hypothesize that chronic glucocorticoids may down-regulate the expression of glucocorticoids receptor (GR) and activate NLRP-1 inflammasome in hippocampal neurons, which may promote neuroinflammation and induce neuronal injury...
