Using a grounded theory approach, the current descriptive qualitative design was conducted with sophomore students to understand the meaning participants gave their freshman experiences with depression. Twelve participants were recruited using scripted class announcements across campus. After informed consent, interviews began with the question: What was the experience of your freshman year in college? All interviews were completed with the primary investigator and transcribed verbatim. Interviews were analyzed using constant comparative methodology...

Individuals with more or stronger social bonds experience enhanced survival and reproduction in various species, though the mechanisms mediating these effects are unclear. Social thermoregulation is a common behaviour across many species which reduces cold stress exposure, body heat loss, and homeostatic energy costs, allowing greater energetic investment in growth, reproduction, and survival, with larger aggregations providing greater benefits. If more social individuals form larger thermoregulation aggregations due to having more potential partners, this would provide a direct link between sociality and fitness...

Introduction: Accumulating evidence suggests that trends in salivary cortisol after awakening may be reliable biological predictors of morbidity and mortality. In a sample of elite military men, our lab recently established summary parameters of morning cortisol as well as their stability across 2 d of repeated sampling. Materials and Methods: In this follow-on study, we evaluated summary parameters and their relationships to theoretically relevant demographic (i...

Many studies have shown the effects of sleep deprivation in several aspects of health and disease. However, little is known about how mitochondrial bioenergetics function is affected under this condition. To clarify this, we developed a simple model of short-term sleep deprivation, in which fruit-flies were submitted to a nocturnal light condition and then mitochondrial parameters were assessed by high resolution respirometry (HRR). Exposure of flies to constant light was able to alter sleep patterns, causing locomotor deficits, increasing ROS production and lipid peroxidation, affecting mitochondrial activity, antioxidant defense enzymes and caspase activity...

BACKGROUND Previous studies have demonstrated that sustained hypoxia in people with obstructive sleep apnea (OSA) impairs upper airway muscle activity, but the underlying mechanism remains poorly understood. As autophagy acts as an important regulator under hypoxia stress, we performed an in vitro investigation of the effects of sustained hypoxia on autophagy of genioglossus muscle-derived stem cells (GG MDSC), an important component of the upper airway muscle. MATERIAL AND METHODS Genioglossus MDSCs were obtained from Sprague-Dawley (SD) rats and identified by using immunofluorescence staining for CD34, Sca-1, and desmin...

The calibrated application of limited duration, cyclic, moderately intense hypoxia-reoxygenation increases cardiac resistance to ischemia-reperfusion stress. These intermittent hypoxic conditioning (IHC) programs consistently produce striking reductions in myocardial infarction and ventricular tachyarrhythmias following coronary artery occlusion and reperfusion, and in many cases, improved contractile function and coronary blood flow. These IHC protocols are fundamentally different from those used to simulate sleep apnea, a recognized cardiovascular risk factor...

The ABCG2 multidrug transporter provides resistance against various endo- and xenobiotics, and protects the stem cells against toxins and stress conditions. We have shown earlier that a GFP-tagged version of ABCG2 is fully functional and may be used to follow the expression, localization and function of this transporter in living cells. In the present work we have overexpressed GFP-ABCG2, driven by a constitutive (CAG) promoter, in HUES9 human embryonic stem cells. Stem cell clones were generated to express the wild-type and a substrate-mutant (R482G) GFP-ABCG2 variant, by using the Sleeping Beauty transposon system...

Startle-induced locomotion is commonly used in Drosophila research to monitor locomotor reactivity and its progressive decline with age or under various neuropathological conditions. A widely used paradigm is startle-induced negative geotaxis (SING), in which flies entrapped in a narrow column react to a gentle mechanical shock by climbing rapidly upwards. Here we combined in vivo manipulation of neuronal activity and splitGFP reconstitution across cells to search for brain neurons and putative circuits that regulate this behavior...

Police officers are frequently exposed to two different types of potentially traumatic events: one dealing with physical threats to self and the other involving the witnessing of harm to others. These different types of traumatic experiences are thought to produce various posttraumatic reactions. Furthermore, sleep problems are also reported as a hallmark of posttraumatic stress disorder. There is evidence, however, that sleep problems may mediate the relationship between posttraumatic stress disorder symptoms and health outcomes, especially physical health and depression...

Clinico-pathological studies that focus on sudden unexpected death (SUD) in the neonatal period are rare. The objective of this study was to elucidate the frequency and pathological spectrum of anatomical causes of death (CODs), found in the setting of sudden unexpected death in neonates (SUD-N), and to correlate the COD with premortem circumstantial information. We conducted a detailed review of all autopsy reports on SUD-N cases at our institution from 1997 to 2015. Analyzed clinical data included obstetrical history, postpartum/neonatal medical course, and circumstances surrounding death...

Background: Dysfunctional uterine bleeding (DUB) is one of the most common gynecological disorders encountered in women during the reproductive age. Yoga therapy has shown promising benefits in several gynecological disorders. Methods: Thirty women between the ages of 20 and 40 years with primary DUB were randomly assigned to a yoga ( n = 15) and a waitlist control group ( n = 15). Participants in the yoga group received a 3-month yoga module and were assessed for hemoglobin values, endometrial thickness (ET), pictorial blood loss assessment chart (PBAC), State-Trait Anxiety Inventory, perceived stress scale, and Pittsburgh Sleep Quality Index (PSQI) before and after a 3-month follow-up period...

REVIEW
Anthony L A Murkar, Joseph De Koninck
Research suggests sleep plays a role in the consolidation of recently acquired memories for long-term storage. rapid eye movement (REM) sleep has been shown to play a complex role in emotional-memory processing, and may be involved in subsequent waking-day emotional reactivity and amygdala responsivity. Interaction of the hippocampus and basolateral amygdala with the medial-prefrontal cortex is associated with sleep-dependent learning and emotional memory processing. REM is also implicated in post-traumatic stress disorder (PTSD), which is characterized by sleep disturbance, heightened reactivity to fearful stimuli, and nightmares...

BACKGROUND: Stress plays a causal role in depression onset, perhaps via alteration of hypothalamic-pituitary-adrenal (HPA) axis functioning. HPA axis hyperactivity has been reported in depression, though inconsistently, and the nature of this relationship remains unclear, partly because cortisol measurement over time has been challenging. Development of hair cortisol assessment, a method that captures cortisol over prolonged periods of time, creates new possibilities. In this study, hair cortisol was incorporated into a prospective and longitudinal study of medical internship, stress and symptoms of depression...

The amygdaloid nuclear complex has been linked to the regulation of emotional behavior and energy regulation in that emotional stress might cause either reduction or enhancement of eating. We examined hypothalamic neuronal origin of feeding/arousal-related peptidergic fibers containing cocaine- and amphetamine-regulated transcript (CART) and neuropeptide Y (NPY) located in the rat amygdala along with its efferent projections to the brainstem monoaminergic nuclei. First, central (CeA) as well as medial (MeA) amygdala, among several amygdaloid subdivisions, exhibited the most prominent NPY or CART immunostaining which consisted of a substantial number of somata as well as labeled fibers...
