Hada Fong-Ha Ieong, Zhen Yuan
Dependence to opiates, including illicit heroin and prescription pain killers, and treatment of the opioid use disorder (OUD) have been longstanding problems over the world. Despite intense efforts to scientific investigation and public health care, treatment outcomes have not significantly improved for the past 50 years. One reason behind the continuing use of heroin worldwide despite such efforts is its highly addictive nature. Brain imaging studies over the past two decades have made significant contribution to the understanding of the addictive properties as to be due in part to biological processes, specifically those in the brain structure and function...

Adaptation to altered osmotic conditions is a fundamental property of living cells and has been studied in detail in the yeast Saccharomyces cerevisiae. Yeast cells accumulate glycerol as compatible solute, controlled at different levels by the High Osmolarity Glycerol (HOG) response pathway. Up to now, essentially all osmostress studies in yeast have been performed with glucose as carbon and energy source, which is metabolised by glycolysis with glycerol as a by-product. Here we investigated the response of yeast to osmotic stress when yeast is respiring ethanol as carbon and energy source...

Toxic effects of cadmium (Cd), a common soil pollutant, are still not very well understood, particularly in regard to its epigenetic impact. Therefore, the aim of this study was to assess DNA methylation changes and their persistence in the earthworm Lumbricus terrestris upon chronic low dose Cd exposure using methylation sensitive amplification polymorphism (MSAP). Moreover, the biomarker response and fitness of the earthworms, as well as the expression of detoxification-related genes (metallothionein (MT) and phytochelatin synthase (PCS)) was evaluated...

BACKGROUND: The National Academies of Sciences, Engineering, and Medicine (formerly the Institute of Medicine) recently recommended inclusion of post-discharge health-related quality of life (HRQoL) and patient-reported outcomes (PROs) metrics to benchmark the quality of trauma care. Currently, these measures are not routinely collected at most trauma centers. We sought to determine the feasibility and value of adding such long-term outcome measures to trauma registries. METHODS: As part of the Functional Outcomes and Recovery after Trauma Emergencies (FORTE) project we included patients with an ISS ≥9, admitted to the Brigham and Women's Hospital in Boston, MA who were identified retrospectively using the institutional trauma registry and contacted 6 or 12-months post-injury to participate in a telephone survey evaluating: HRQoL (Short Form-12 [SF-12]), PROs (Trauma Quality of Life [T-QoL]), post-traumatic stress disorder (PTSD), return to work, residential status, and healthcare utilization...

The weekend is usually seen as a window of recovery. Thus, sleep before a day off may be less impaired than that before a workday. However, very few polysomnographical studies have investigated this hypothesis. Therefore, the aim of the present study was to compare sleep before a workday with that before a weekend. Seventeen teachers participated. Sleep was recorded with polysomnography on one weekday night during the workweek, and on a workday (Friday) followed by a day off. Sleep diaries and actigraphs were also used...

Many studies on sleep deprivation effects lack data regarding the recovery period. We investigated the 2-day homeostatic and circadian sleep recovery response to 24 h of total sleep deprivation (TSD) induced by brief rotation of an activity wheel. Eight mice were implanted with telemetry transmitters (DSI F40-EET) that recorded simultaneously their electroencephalography (EEG), locomotor activity and temperature during 24 h of baseline (BSL), TSD and 2 days of recovery (D1 and D2). In a second experiment, two groups of five non-implanted mice underwent TSD or ad libitum sleep, after which they were killed, adrenal glands were weighed and blood was collected for analysis of corticosterone concentration...

Bed rest has been an established treatment in the past prescribed for critically illness or convalescing patients, in order to preserve their body metabolic resource, to prevent serious complications and to support their rapid path to recovery. However, it has been reported that prolonged bed rest can have detrimental consequences that may delay or prevent the recovery from clinical illness. In order to study disuse-induced changes in muscle and bone, as observed during prolonged bed rest in humans, an innovative new model of muscle disuse for rodents is presented...

Mouse models show that experimental stress mimicking prolonged life-stress exposure enhances neurogenic inflammation, induces adaptive immunity cytokine-imbalance characterized by a shift to Type 1 T-helper cell cytokines and increases apoptosis of epithelial cells. This affects hair growth in otherwise healthy animals. In this study, we investigate whether a prolonged naturalistic life-stress exposure affects cytokine balance and hair parameters in healthy humans. 33 (18 exam, 15 comparison) female medical students with comparable sociobiological status were analyzed during a stressful final examination period, at three points in time (T) 12 weeks apart...

BACKGROUND: The purpose was to investigate if potentially stressful reminders of the intensive care unit (ICU) stay influenced variability in transient skin conductance responses, and whether such changes were associated with post-traumatic stress symptoms (PTSS), and development of symptoms over time. METHODS: Thirty patients with an ICU length of stay > 48 h were included in the study. Within the week after ICU discharge (T1), patients were exposed to authentic ICU sound and questions regarding traumatic ICU memories while skin conductance reactivity was monitored...

Background. Nitric oxide can successfully compete with oxygen for sites of electron-transport chain in conditions of myocardial hypoxia. These features may prevent excessive oxidative stress occurring in cardiomyocytes during sudden hypoxia-reoxygenation. Aim. To study the action of the potent stable NO donor dinitrosyl iron complex with glutathione (Oxacom®) on the recovery of myocardial contractile function and Ca(2+) transients in cardiomyocytes during hypoxia-reoxygenation. Results. The isolated rat hearts were subjected to 30 min hypoxia followed by 30 min reoxygenation...

Dwarf bamboo-dominated forests are often subjected to temporary periods of drought due to rising air temperature and decreasing rainfall. Nevertheless, the relationship among CO2 assimilation, photoprotective pathways and metabolism of reactive oxygen species (ROS) remains unexplored in bamboo species. Changes in leaf gas exchange, chlorophyll fluorescence, energy partitioning, antioxidative system and compounds related to ROS metabolism in Fargesia rufa plants subjected to drought and subsequent rewatering were analyzed...

Flavonol bisglycosides accumulate in plant vegetative tissues in response to abiotic stress, including simultaneous environmental perturbations (i.e., nitrogen deficiency and low temperature, NDLT), but disappear with recovery from NDLT. Previously, we determined that a recombinant Arabidopsis β-glucosidase (BGLU), BGLU15, hydrolyzes flavonol 3-O-β-glucoside-7-O-α-rhamnosides and flavonol 3-O-β-glucosides, forming flavonol 7-O-α-rhamnosides and flavonol aglycones, respectively. In this study, the transient expression of a BGLU15-Cherry fusion protein in onion epidermal cells demonstrated that BGLU15 was localized to the apoplast...

Environmental perturbations can strongly affect community processes and ecosystem functions by acting primarily as a subsidy that increases productivity, a stress that decreases productivity, or both, with the predominant effect potentially shifting from subsidy to stress as the overall intensity of the perturbation increases. While perturbations are often considered along a single axis of intensity, they consist of multiple components (e.g., magnitude, frequency, and duration) that may not have equivalent stress and/or subsidy effects...

The return towards resting homeostasis in the post-exercise period has the potential to represent the internal training load of the preceding exercise bout. However, the relative potential of metabolic and autonomic recovery measurements in this role has not previously been established. Therefore the aim of this study was to investigate which of 4 recovery measurements was most closely associated with Borg's Rating of Perceived Exertion (RPE), a measurement widely acknowledged as an integrated measurement of the homeostatic stress of an exercise bout...

Because stress is a significant risk factor for depression, many animal models of depression employ chronic stress as a precipitating event. However, almost without exception, stress-induced animal models of depression focus on a single bout of depression and therefore, they do not provide any means to understand the typical cycling of mood observed in most patients with depression. Here we assessed whether repeated cycles of exposure to the stress hormone corticosterone would sensitize depression-like behavior...

Beside the high post-cryogenic recovery rate, a reinstated scale of secondary metabolites in recovered plant tissues represents another inevitable aspect of an effective cryopreservation protocol for medicinal plants. The current study was aimed at evaluation of the elicitation potential of cryogenic treatment on secondary metabolism of some Hypericum species. In agreement with our assumption, the cold stimuli applied during the pre-cryogenic phase increased the tolerance to low temperatures (-196°C) in H...

Pocilloporids are one of the major reef-building corals in the eastern tropical Pacific (ETP) and also the most affected by thermal stress events, mainly those associated with El Niño/Southern Oscillation (ENSO) periods. To date, coral growth parameters have been poorly reported in Pocillopora species in the northeastern region of the tropical Pacific. Monthly and annual growth rates of the three most abundant morphospecies (P. cf. verrucosa, P. cf. capitata, and P. cf. damicornis) were evaluated during two annual periods at a site on the Pacific coast of Mexico...

The present study was conducted to investigate the effects of salvianolate on perioperative oxidative stress and plasma Intermedin/adrenomedullin 2 (IMD/ADM2) in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI). The clinical data of 108 patients with AMI treated by PCI were retrospectively analyzed. According to the use of salvianolate in perioperative period, the patients were divided into the study group (n=62) and the control group (n=46). The control group was given routine treatment while the study group was given routine treatment combined with intravenous infusion of salvianolate (200 mg administered once at 24 h before operation, once/day after operation, 1 week later, the curative effect was observed)...
