A subset of patients with depression have elevated levels of inflammatory cytokines, and some studies demonstrate interaction between inflammatory factors and treatment outcome. However, most studies focus on only a narrow subset of factors in a patient sample. In the current study, we analyzed broad immune profiles in blood from patients with treatment-resistant depression (TRD) at baseline and following treatment with the glutamate modulator ketamine. Serum was analyzed from 26 healthy control and 33 actively depressed TRD patients free of antidepressant medication, and matched for age, sex and body mass index...

BACKGROUND: Intravenous iron is widely used to control anemia in dialysis patients and limits costs related to erythropoiesis-stimulating agents (ESA). Current guidelines do not clearly set upper limits for serum ferritin (SF) and transferrin saturation (TSAT). International surveys such as the Dialysis Outcomes and Practice Patterns Study (DOPPS) showed that this lack of upper limits potentially led nephrologists to prescribe iron infusions even for patients with a high SF. Recent publications have suggested a risk of short- and long-term adverse effects related to iron overload...

Rationale: Hypertension remains to be a global public health burden and demands novel intervention strategies such as targeting T cells and T cell-derived cytokines. Mineralocorticoid receptor (MR) antagonists have been clinically used to treat hypertension. However, the function of T cell MR in blood pressure (BP) regulation has not been elucidated. Objective: We aim to determine the role of T cell MR in BP regulation and to explore the mechanism. Methods and Results: Using T cell MR knockout (TMRKO) mouse in combination with angiotensin II (AngII)-induced hypertensive mouse model, we demonstrated that MR deficiency in T cells strikingly decreased both systolic and diastolic BP, and attenuated renal and vascular damage...

Variations in circulating corticosterone (Cort) are driven by the paraventricular nucleus of the hypothalamus (PVN), mainly via the sympathetic autonomic nervous system (ANS) directly stimulating Cort release from the adrenal gland and via corticotropin-releasing hormone targeting the adenohypophysis to release adrenocorticotropic hormone (ACTH). Cort feeds back through glucocorticoid receptors (GRs). Here we show in male Wistar rats that PVN neurons projecting to the adrenal gland do not express GRs, leaving the question of how the ANS in the PVN gets information about circulating Cort levels to control the adrenal...

BACKGROUND: Hemorrhagic shock is the leading cause of trauma-related death in the military setting. Definitive surgical treatment of a combat casualty can be delayed and life-saving fluid resuscitation might be necessary in the field. Therefore, improved resuscitation strategies are critically needed for prolonged field and en route care. We developed an automated closed-loop control system capable of titrating fluid infusion to a target endpoint. We used the system to compare the performance of a decision table algorithm (DT) and a fuzzy logic controller (FL) to rescue and maintain the mean arterial pressure (MAP) at a target level during hemorrhages...

PURPOSE OF REVIEW: The recent discovery of effective systemic treatments for melanoma has dramatically improved the prognosis for patients with advanced disease. As a result, the multidisciplinary management of melanoma has evolved significantly. In the past decades surgery was reserved for symptomatic palliation in patients with metastatic melanoma. Today surgical treatment of patients responding to systemic therapies has become an integral part of disease control. RECENT FINDINGS: Current efforts are focused on minimizing the morbidity of surgery (laparoscopic inguinal lymph node dissection, selective completion lymphadenectomy) as well as combining surgery with systemic therapy in novel ways (neoadjuvant targeted and/or immunotherapy, isolated limb infusion/perfusion with systemic immunotherapy)...

The AP2/ERF family is a plant-specific transcription factor (TF) family whose members have been associated with various developmental processes and stress tolerance. Here, we functionally characterized the drought-inducible OsERF48, a group Ib member of the rice ERF family with four conserved motifs, CMI-1, -2, -3 and -4. A transactivation assay in yeast revealed that the C-terminal CMI-1 motif was essential for OsERF48 transcriptional activity. When OsERF48 was overexpressed in an either a root-specific (ROX(OsERF48) ) or whole-body (OX(OsERF48) ) manner, transgenic plants showed a longer and denser root phenotype compared to the nontransgenic (NT) controls...

PURPOSE: Propofol dosing based on total body weight (TBW) can lead to overdosing in morbidly obese (MO) patients. Our aim was to determine whether an induction dose of propofol based on a bispectral index (BIS) target is better for achieving loss of consciousness in MO patients than dosing based on lean body weight (LBW). METHODS: Sixty MO patients with a body mass index (BMI) of ≥ 40 kg·m(-2) were randomized to either BIS- or LBW-based propofol dosing groups...

Recent studies have demonstrated that leptin can prolong life chronically in rats with poorly-controlled type 1 diabetes (T1D). Multiple explanations have been proposed to explain leptin's chronic antihyperglycemic effect, including suppression of glucagon release and/or signaling, reductions in hyperphagia and ectopic lipid content, and improvements in insulin sensitivity; it is leptin's ability to reduce plasma glucose relies on all of these effects. In addition, leptin reverses hyperglycemia and diabetic ketoacidosis (DKA) acutely, within 6 hours of leptin infusion, by suppressing hypothalamic-pituitary-adrenal (HPA) axis activity in insulinopenic rats...

The European Society for Medical Oncology (ESMO) have stressed that the option for treating oligometastatic disease is a strategy of local ablative therapy, the goal of which is to improve disease control. The spectrum of the local ablative therapy toolbox described by the ESMO includes surgical R0 resection, percutaneous ablation and intra-arterial therapies, the choice of treatment being left to the multidisciplinary team. Interventional therapy involving image-guided treatment offers the possibility of less invasive treatments for colorectal cancer metastases in the liver, lung and bone by preserving from toxicity distant healthy organs or even parts of the diseased organs...

The death of mature oligodendrocytes (OLs) which are the sole myelinating cells of the central nervous system (CNS), leads to demyelination and functional deficits. Currently, there is lack of effective remyelination therapies for patients with demyelinating diseases. MicroRNAs (miRNAs) mediate OL function. We hypothesized that miR-146a, by inactivating interleukin-1 receptor-associated kinase 1 (IRAK1), promotes differentiation of oligodendrocyte progenitor cells (OPCs) and thereby enhances remyelination. To test this hypothesis, a demyelination model induced by a cuprizone (CPZ) diet was employed, in which C57BL/6J mice were fed with a CPZ diet for 5weeks...

Continuous adjustment of Propofol in manual delivery of anesthesia for conducting a surgical procedure overburdens the workload of an anesthetist who is working in a multi-tasking scenario. Going beyond manual administration and Target Controlled Infusion, closed-loop control of Propofol infusion has the potential to offer several benefits in terms of handling perturbations and reducing the effect of inter-patient variability. This paper proposes a closed-loop automated drug administration approach to control Depth Of Hypnosis in anesthesia...

3-Bromopyruvate (3BP) is a promising effective anticancer drug against many different tumors in children and adults. 3BP exhibited strong anticancer effects in both preclinical and human studies e.g. energy depletion, oxidative stress, anti-angiogenesis, anti-metastatic effects, targeting cancer stem cells and antagonizing the Warburg effect. There is no report about 3BP metabolism to guide researchers and oncologists to improve clinical practice and prevent drug resistance. In this article, we provide evidences that 3BP is metabolized through glutathione (GSH) conjugation as a novel report where 3BP was confirmed to be attached to GSH followed by permanent loss of pharmacological effects in a picture similar to cisplatin...
