the prevalence of ventricular assist devices (VADs) is increasing as advanced cardiac therapies progress. These patients commonly require non-cardiac surgical procedures (NCS), although data are scant regarding the safety, timing, and operations that may safely be performed. We aim to describe our experience with VAD patients undergoing NCS. We retrospectively reviewed records on patients who underwent NCS after VAD implantation between 2013 and 2015 at a single Joint Commission-accredited VAD institution. Data collection included demographics, ischemic cardiomyopathy or nonischemic cardiomyopathy, operative details, and perioperative anticoagulation management and outcomes...

REVIEW
Andreas Nicodemou, Lubos Danisovic
Mesenchymal stem (stromal) cells (MSCs) possess unique biological characteristics such as plasticity, long term self-renewal, secretion of various bioactive molecules and ability of active migration to the diseased tissues that make them unique tool for regenerative medicine, nowadays. Until now MSCs were successfully derived from many tissue sources including bone marrow, umbilical cord, adipose tissue, dental pulp etc. The crucial step prior to their in vitro expansion, banking or potential clinical application is their separation...

Gemma McGregor, Jenni Harvey
Growing evidence indicates that the endocrine hormone leptin regulates hippocampal synaptic function in addition to its established role as a hypothalamic satiety signal. Indeed, numerous studies show that leptin facilitates the cellular events that underlie hippocampal learning and memory including activity-dependent synaptic plasticity and glutamate receptor trafficking, indicating that leptin may be a potential cognitive enhancer. Although there has been extensive investigation into the modulatory role of leptin at hippocampal Schaffer collateral (SC)-CA1 synapses, recent evidence indicates that leptin also potently regulates excitatory synaptic transmission at the anatomically distinct temporoammonic (TA) input to hippocampal CA1 neurons...

A large volume of the waste produced across the world is composed of polymers from plastic wastes such as polyethylene (HDPE or LDPE), polypropylene (PP), and polyethylene terephthalate (PET) amongst others. For years, environmentalists have been looking for various ways to overcome the problems of such large quantities of plastic wastes being disposed of into landfill sites. On the other hand, the usage of synthetic polymers as oil sorbents in particular, polyolefins, including polypropylene (PP) and polyethylene (PE) have been reported...

Human populations are using oceans as their household dustbins, and microplastic is one of the components which are not only polluting shorelines but also freshwater bodies globally. Microplastics are generally referred to particles with a size lower than 5 mm. These microplastics are tiny plastic granules and used as scrubbers in cosmetics, hand cleansers, air-blasting. These contaminants are omnipresent within almost all marine environments at present. The durability of plastics makes it highly resistant to degradation and through indiscriminate disposal they enter in the aquatic environment...

REVIEW
Suruchi Garg, Shweta Manchanda
Platelet-rich plasma (PRP) has emerged as a new treatment modality in regenerative plastic surgery and dermatology. PRP is a simple, cost-effective and feasible treatment option with high patient satisfaction for hair loss and can be regarded as a valuable adjuvant treatment modality for androgenic alopecia and other types of non-scarring alopecias. Authors have proposed a hair model termed "Golden anchorage with 'molecular locking' of ectodermal and mesenchymal components for survival and integrity of hair follicle (HF)" in this article...

The manipulation of neural plasticity as a means of intervening in the onset and progression of stress-related disorders retains its appeal for many researchers, despite our limited success in translating such interventions from the laboratory to the clinic. Given the challenges of identifying individual genetic variants that confer increased risk for illnesses like depression and post-traumatic stress disorder, some have turned their attention instead to focusing on so-called "master regulators" of plasticity that may provide a means of controlling these potentially impaired processes in psychiatric illnesses...

REVIEW
M M Leiva-Juárez, J K Kolls, S E Evans
Lung epithelial cells are increasingly recognized to be active effectors of microbial defense, contributing to both innate and adaptive immune function in the lower respiratory tract. As immune sentinels, lung epithelial cells detect diverse pathogens through an ample repertoire of membrane-bound, endosomal, and cytosolic pattern-recognition receptors (PRRs). The highly plastic epithelial barrier responds to detected threats via modulation of paracellular flux, intercellular communications, mucin production, and periciliary fluid composition...

PURPOSE: Locally advanced tongue carcinomas (LATCs) in inoperable lesions are managed with external beam radiation therapy (EBRT) and chemotherapy. In our institution, the boost to the gross tumor volume is delivered with high-dose-rate brachytherapy (HDR-BT) after EBRT. We review the outcome of these patients when HDR-BT is added as a boost. METHODS AND MATERIALS: From May 2000 to December 2014, a total of 24 patients with LATC, nonsurgical oral tongue, and base of tongue carcinomas were treated with EBRT and with interstitial plastic tubes for brachytherapy; median dose was 18-24 Gy in 6-8 fractions after 50-60 Gy of EBRT...

Stem cells are at the basis of organismal development, characterized by their potential to differentiate towards specific lineages upon receiving proper signals. To understand the molecular principles underlying gain and loss of pluripotency, proteomics plays an increasingly important role owing to technical developments in mass spectrometry and implementation of innovative biochemical approaches. Here we review how quantitative proteomics has been used to investigate protein expression, localization, interaction and modification in stem cells both in vitro and in vivo, thereby complementing other omics approaches to study fundamental properties of stem cell plasticity...

BACKGROUND: Scar management is critical for every plastic surgeon's practice and, ultimately, the patient's satisfaction with his or her aesthetic result. Despite the critical nature of this component of routine post-operative care, there has yet to be a comprehensive analysis of the available literature over the last decade to assess the best algorithmic approach to scar care. To this end, a systematic review of best practices in preventative scar management was conducted to elucidate the highest level of evidence available on this subject to date...

PURPOSE OF REVIEW: This review summarizes current and prior observations regarding transfusion-related immunomodulation (TRIM) and puts these ideas into a modern immunological context, incorporating concepts from innate, adaptive, and nutritional immunity. We propose that TRIM research focus on determining whether there are specific, well-defined immunosuppressive effects from transfusing 'pure' red blood cells (RBCs) themselves, along with the by-products produced by the stored RBCs as a result of the 'storage lesion...

Glioblastoma (GBM) is the most prevalent and malignant brain tumor, displaying notorious resistance to conventional therapy, partially due to molecular and genetic heterogeneity. Understanding the mechanisms for gliomagenesis, tumor stem/progenitor cell propagation and phenotypic diversity is critical for devising effective and targeted therapy for this lethal disease. The basic helix-loop-helix transcription factor OLIG2, which is universally expressed in gliomas, has emerged as an important player in GBM cell reprogramming, genotoxic resistance, and tumor phenotype plasticity...

We review research on brain development and brain evolution in the wasp family Vespidae. Basic vespid neuroanatomy and some aspects of functional neural circuitry are well-characterized, and genomic tools for exploring brain plasticity are being developed. Although relatively modest in terms of species richness, the Vespidae include species spanning much of the known range of animal social complexity, from solitary nesters to highly eusocial species with some of the largest known colonies and multiple reproductives...

REVIEW
Michal Horowitz
The primary outcome of heat acclimation is increased thermotolerance, which stems from enhancement of innate cytoprotective pathways. These pathways produce "ON CALL" molecules that can combat stressors to which the body has never been exposed, via cross-tolerance mechanisms (heat acclimation-mediated cross-tolerance-HACT). The foundation of HACT lies in the sharing of generic stress signaling, combined with tissue/organ- specific protective responses. HACT becomes apparent when acclimatory homeostasis is achieved, lasts for several weeks, and has a memory...

The discovery of the Sry gene in 1990 triggered a revolution in our understanding of sex determination. More recently, advances in non-model organisms have been fuelled by the rapid evolution of affordable genome and transcriptome technologies. This Review considers the unusual plasticity in the bipotential system of sex determination and some of the diverse mechanisms that have evolved to control this critical developmental decision, including strong genetic pathways, environmental influences and epigenetic regulation...

Neural stem cells (NSCs) persist throughout life in the dentate gyrus and the ventricular-subventricular zone (V-SVZ), where they continuously provide new neurons and some glia. These cells are found in specialized niches that regulate quiescence, activation, differentiation, and cell fate choice. A key aspect of the regulatory niche is the vascular plexus, which modulates NSC behavior during tissue homeostasis and regeneration. During aging, NSCs become depleted and dysfunctional, resulting in reduced neurogenesis and poor brain repair...
