Sevoflurane suppresses neuroblastoma cell spreading along with breach and causes apoptosis through miR-144-3p/YAP1 axis.
Humans' everyday experience of the world is influenced by our moods. Moods are consciously accessible affective states that extend over time that are characterized by their valence and arousal. They also likely have a long evolutionary heritage and serve as an important adaptive affective mechanism. When they become maladaptive or overly biased, pathological affective states such as depression can emerge. Despite the importance of moods for human experience, little is known about their causal neurobiological mechanisms. In humans, limitations related to methods and interpretations of the data prevent causal investigations into the origins of mood, highlighting the importance of animal models. Nonhuman primates that share key neuroanatomical, affective, and social features with humans will be essential to uncovering their foundation. Identifying and validating mood-like states in animals is, however, challenging not least because mood is a human construct requiring verbal communication. Here we outline a theoretical framework for animal models of human mood, drawing upon established psychological literature where it exists before reviewing the extant studies of non-human primate models of mood-like states.
Hyperkalemia (HK) is a serious medical condition that can cause potentially fatal cardiac arrhythmias. Patients with heart failure (HF) are at risk of HK due to underlying chronic kidney disease and use of guideline-recommended renin-angiotensin-aldosterone system inhibitors. Patiromer, a sodium-free, non-absorbed potassium (K
) binder, is indicated for the treatment of HK.

To evaluate the consistency of patiromer's effect on lowering serum K
in patients with HF and HK using pooled data from three clinical trials.

This post-hoc analysis evaluated the efficacy and safety of patiromer for management of HK over a 4-week treatment period using combined data from three clinical trials (AMETHYST-DN, OPAL-HK and TOURMALINE). Eligible patients had HK (serum K
 > 5.0 mEq/L) at study entry. Starting doses of patiromer ranged from 8.4 to 33.6 g/day. In this analysis, efficacy was assessed as the mean (± standard error [SE]) change in serum K
from baseline to Week 4. Safety outcomes evaluated included the % of patients with HF and in 3% of patients without HF.

In this pooled analysis of patients with HK, patiromer was generally well tolerated and reduced serum K
similarly in patients with and without HF over 4 weeks.

Breast radiotherapy is associated with a risk of ischemic heart disease. Limiting left anterior descending coronary artery (LADCA) exposure might possibly reduce coronary risk. However, its manual delineation is poorly reproducible and its auto-segmentation remains unreliable. This study aims to define and characterize a high-risk cardiac zone (HRCZ) as a LADCA surrogate and to implement its auto-segmentation.

Forty breast cancer patients treated with adjuvant IMRT were included. We delineated the LADCA and eight HRCZ, defined as 1cm-thick cardiac wall segments centered on the LADCA with symmetrical lateral margins defining the HRCZ width (ranging between 1 and 8cm). We retrieved mean and maximum doses to the LADCA and to the HRCZ and calculated relative dose variations. We constituted an atlas with the HRCZ contours of 20 patients. Based on this latter, a commercial atlas-based auto-segmentation software delineated HRCZ for the remaining 20 patients and performances were evaluated using distance metrics.

Relative maximum dose variations were systematically positive and increased with HRCZ width, rising from 7.2% to 112.8% for right-sided irradiation (with a sharp increase above 4cm), and from 9.5% to 30.4% for left-sided irradiation. Auto-segmentation performances asymptotically improved with HRCZ width Dice similarity coefficient values were 0.62 for a 3cm width and 0.69 for an 8cm width.

A 3.5cm-wide HRCZ is a reliable LADCA surrogate for breast radiotherapy. Applying maximum dose constraints to the HRCZ could limit LADCA exposure. Auto-segmentation algorithms can reliably delineate HRCZ.

Hemolytic activity, either observed in vitro or in vivo, showed similar toxicity levels for all samples. Erythrocytes of different species varied in their sensitivity to the venom pool, equines being the most sensitive and sheep the most resistant to direct hemolytic action. Local and systemic myotoxicity was evidenced by either the elevation of serum creatine kinase and/or histopathological lesions, observed in different muscles. All samples caused significant pathological alterations; pulmonary, cardiac, renal and skeletal muscle lesions were substantive and can be related to the pathophysiological mechanisms of envenomation. The venoms from different apiaries and regions of the Buenos Aires province showed very similar toxicological characteristics. These results suggest that severity of envenomation in case of a swarming could therefore be more related to the number of bees than to the differential toxicity of the venom from different regions of the province. This is the first study on the toxicity and toxicological characteristics of Apis mellifera venom in Argentina.
