Alexander A Kamnev, Anna V Tugarova
In this review, the unique possibilities are considered of the (57)Fe transmission (TMS) and (57)Co emission (EMS) variants of Mössbauer (nuclear γ-resonance) spectroscopy as nondestructive techniques with minimal sample preparation/treatment and a significant analytical potential, with a focus on the analysis of cation-binding sites in metalloproteins. The techniques are shown to provide unique structural and quantitative information on the coordination microenvironment, the chemical state and transformations of the Mössbauer nuclides in sophisticated metal-containing proteins, including those within complicated supramolecular structures, and in microbial cells or tissues...

REVIEW
Kevin Ita
Over the last number of years, a significant body of evidence has shown the benefit of using dissolving microneedles (DMNs) for transdermal drug delivery. These devices are prepared from a wide range of materials such as sugars and polymers. DMNs are mainly fabricated by micromolding, photopolymerization, drawing lithography and droplet-airborne blowing. In this review, we have focused on the advances made in the field in recent years using a representative set of studies. Although the list of studies is not exhaustive, they highlight the challenges encountered such as the need to increase mechanical strength as well as medication dose while ensuring fast release of the active ingredient...

Nonpoint source (NPS) pollution produced by human activities in rural areas has induced excessive nutrient input into surface waters and the decline of water quality. The essence of NPS pollution is the transport of nutrients between soil and water. Traditional NPS pollution control strategies, however, are mainly based on the solid and liquid phases, with little focus on the bio-phase between water and soil. The pollutants produced from NPS can be regarded as a resource if recycled or reused in an appropriate way in the agricultural ecosystem...

The effects of Wnt signaling modifiers on cell proliferation, seem to be cell specific. Enhancing the proliferation of subventricular zone (SVZ) progenitors has been in the focus of research in recent years. Here we investigate the effect of CHIR99021, a Glycogen Synthase Kinase 3 (GSk-3) inhibitor, on SVZ progenitor's proliferation both in vivo and in vitro. Neural stem cells were extracted from the adult C57bl/6 by mincing and trypsin treatment followed by culturing in specific medium. Sphere cells formed within about 7-10days and were characterized by immunostaining...

BACKGROUND: Arteriovenous (AV) loops can be utilized in a single- or two-stage approach in free flap reconstruction when proper vessels are not available. However, there exists no consensus on which method leads to superior microsurgical and patient outcomes. The purpose of this article was to review single- versus two-stage AV loops utilized in free flap reconstruction with a focus on complications and overall outcomes. METHODS: A systematic review of AV loops for autologous free tissue transfer was conducted...

Recent reports estimate that 0.6% of adults in the United States, or approximately 1.4 million persons, identify as transgender. Despite gains in rights and media attention, the reality is that transgender persons experience health disparities, and a dearth of research and evidence-based guidelines remains regarding their specific health needs. The lack of research to characterize cardiovascular disease (CVD) and CVD risk factors in transgender populations receiving cross-sex hormone therapy (CSHT) limits appropriate primary and specialty care...

Smartphone use in clinical settings and in medical education has been on the rise, benefiting both health care and health care providers. Studies have shown, however, that some health care facilities and providers are reluctant to switch to smartphones due to the threat of mixing personal apps with clinical care applications and the possibility that distraction created by smartphone use could lead to medication errors and errors linked to procedures, treatments, or tests. The purpose of this research was to examine the effects of smartphones in a clinical setting and for medical education, to determine their overall impact...

David P White
The primary pathological event in the disorder obstructive sleep apnea (OSA) is the partial or complete closure of the pharyngeal airway during sleep in an individual with a widely patent airway during wakefulness. This yields an apnea or hypopnea with resulting hypoxia and hypercapnia, and most often requires an arousal to terminate the event. These events occur in a repetitive manner during sleep, yielding intermittent hypoxia and sleep fragmentation with their associated adverse effects on the health and quality of life of the afflicted individual...

Continuous positive airway pressure (CPAP) is the primary treatment of obstructive sleep apnea/hypopnea syndrome (OSA). Most sleep physicians are in agreement that a certain number of OSA patients cannot or will not use CPAP. Although other conservative therapies, such as oral appliance, sleep hygiene, and sleep positioning, may help some of these patients, there are many who fail all conservative treatments. As sleep surgeons, we have the responsibility to screen patients for both symptoms and signs of OSA...

Schizophrenia is a disorder that shows a progressive course in 30-50% of the people concerned. The biology of chronification and progression is unclear. Genetic aspects may play a role, but details are unresolved. The fact that immune-mediated and autoimmune disorders such as rheumatoid arthritis or multiple sclerosis have a very similar course as schizophrenia has focused the interest on the immunopathogenesis of schizophrenia. A clear immune marker for neuroprogression in schizophrenia or psychosis could not be identified up to now, but a proinflammatory immune state (increased markers of cellular immunity) is regularly found in schizophrenia, e...

We performed a systematic review of the literature to establish conclusive evidence of risk factors for community-acquired pneumonia (CAP). Observational studies (cross-sectional, case-control, and cohort studies) the primary outcome of which was to assess risk factors for CAP in both hospitalized and ambulatory adult patients with radiologically confirmed pneumonia were selected. The Newcastle-Ottawa Scale specific for cohort and case-control designs was used for quality assessment. Twenty-nine studies (20 case-control, 8 cohort, and 1 cross-sectional) were selected, with 44...

Over the past few decades there has been a significant increase in research focusing on the pathophysiology, diagnosis, and treatment of sleep apnea. However, there is still a long way to go in creating standard evidence-based medical practice for the diagnosis, evaluation, and treatment of sleep apnea patients. Current and future directions of sleep surgery and other treatments are discussed here.

Traditionally, the neurobiology of major depressive disorder (MDD) has been largely considered from the perspective of the state of major depressive episodes (MDE) versus being in remission, but the current accumulation of disease markers, largely acquired cross-sectionally, is strongly suggestive of neuroprogressive aspects of MDD. This chapter focuses on the changes in disease markers involved in the reorganization of the nervous system in MDD, including the translocator protein (TSPO; an index of microglial activation), glial fibrillary acidic protein (GFAP; an index of astroglial activation), [11C]harmine (a marker of monoamine oxidase A; MAO-A), and several other indices (metabotropic glutamate receptor 5 [mGluR5], excitatory amino acid transporters, and magnetic resonance imaging spectroscopy measurements) of glutamate dysregulation...

There is a growing emphasis on the relationship between the complexity and diversity of the microorganisms that inhabit our gut (human gastrointestinal microbiota) and brain health. The microbiota-gut-brain axis is a dynamic matrix of tissues and organs including the brain, glands, gut, immune cells, and gastrointestinal microbiota that communicate in a complex multidirectional manner to maintain homeostasis. Changes in this environment may contribute to the neuroprogression of stress-related disorders by altering physiological processes including hypothalamic-pituitary-adrenal axis activation, neurotransmitter systems, immune function, and inflammatory responses...

When interacting with other people, both children's biological predispositions and past experiences play a role in how they will process and respond to social-emotional cues. Children may partly differ in their reactions to such cues because they differ in the threshold for perceiving such cues in general. Theoretically, perceptual sensitivity (i.e., the amount of detection of slight, low-intensity stimuli from the external environment independent of visual and auditory ability) might, therefore, provide us with specific information on individual differences in susceptibility to the environment...

Cell targeting peptides (CTP) are small peptides which have high affinity and specificity to a cell or tissue targets. They are typically identified by using phage display and chemical synthetic peptide library methods. CTPs have attracted considerable attention as a new class of ligands to delivery specifically therapeutic and diagnostic agents, because of the fact they have several advantages including easy synthesis, smaller physical sizes, lower immunogenicity and cytotoxicity and their simple and better conjugation to nano-carriers and therapeutic or diagnostic agents compared to conventional antibodies...

Over the last decade, the coagulation factor XIIa (FXIIa) has seen renewed interest as a therapeutic target. Indeed, its inhibition could offer a protection against thrombosis without increasing the risk of bleeding. Moreover, it could answer the need for a safe prevention of blood-contacting medical devices-related thrombosis. Among the FXII and FXIIa inhibitors already described in literature, organic small-molecular-weight inhibitors are rather left behind. In this study, we were focused on the discovery and assessment of water soluble small molecules...
