REVIEW
Martina Ondrovics, Andrea Hoelbl-Kovacic, Daniela Alexandra Fux
Opioids are potent drugs that are widely used to control wound or cancer pain. Increasing evidence suggest that opioids mediate clinically relevant effects that go beyond their classical role as analgesics. Of note, opioids appear to modulate angiogenesis - a process that is critical in wound healing and cancer progression. In this review, we focus on pro- and anti-angiogenic facets of opioids that arise from the activation of individual opioid receptors and the usage of individual concentrations or application routes...

Mitochondria serve a primary role in energy maintenance but also function to govern levels of mitochondria-derived reactive oxygen species (mROS). ROS have long been established to play a critical role in tumorigenesis and are now considered to be integral to the regulation of diverse signaling networks that drive proliferation, tumor cell survival and malignant progression. mROS can damage DNA, activate oncogenes, block the function of tumor suppressors and drive migratory signaling. The mitochondrion's oxidant scavenging systems including SOD2, Grx2, GPrx, Trx and TrxR are key of the cellular redox tone...

REVIEW
Allyson K Roof, Arthur Gutierrez-Hartmann
Conserved signaling pathways are critical regulators of pituitary homeostasis and, when dysregulated, contribute to adenoma formation. Pituitary adenomas are typically benign and rarely progress to malignant cancer. Pituitary and other neuroendocrine cell types often display non-proliferative responses to ERK and PI3K, in contrast to non-endocrine cell types which typically proliferate in response to ERK and PI3K activation. These differences likely contribute to the infrequent progression to malignancy in many endocrine tumors...

CONTEXT: Sexual and gender minority adolescents are underrepresented in HIV research, partly because institutional review boards (IRBs) are reluctant to waive parental permission requirements for these studies. Understanding teenagers' perspectives on parental permission and the risks and benefits of participating in HIV research is critical to informing evidence-based IRB decisions. METHODS: Data from 74 sexual and gender minority adolescents aged 14-17 who participated in an online focus group in 2015 were used to examine perspectives on the risks and benefits of participation in a hypothetical HIV surveillance study and the need for parental permission and adequate protections...

Transposable elements (TEs) are DNA elements that can change their position within the genome, with the potential to create mutations and destabilize the genome. As such, special molecular systems have been adopted in animals to control TE activity in order to protect the genome. PIWI proteins, in collaboration with PIWI-interacting RNAs (piRNAs), are well known to play a critical role in silencing germline TEs. Although initially thought to be germline-specific, the role of PIWI-piRNA pathways in controlling TEs in somatic cells has recently begun to be explored in various organisms, together with the role of endogenous small interfering RNAs (endo-siRNAs)...

Designing effective exercise training programs is important for novice, regular and elite individuals desiring improvements in physical fitness and performance outcomes without experiencing deleterious physiological or performance effects. The purpose of this research was to understand the impact of training intensity on the effectiveness of training program outcomes. Synthesized analyses of 31 studies provided an overall magnitude for the impact of training program intensity on effect size (ES). Meta-analyses were conducted using meta-regression models to assess the impact of training program intensity and the other moderators of training frequency, training weeks, age, ability level, and type of physical exercise training...

An expanding list of immunomodulatory or immunosuppressive monoclonal antibodies (mAbs) and biologic therapeutics is currently entering clinical practice, particularly in the areas of oncology, transplantation and autoimmune disorders. These agents are directed against molecules or cells involved in inflammation and immunity and may therefore be associated with serious and opportunistic infections. The purpose of this review was to critically analyse the literature on invasive fungal infections (IFIs) occurring in association with mAbs and fusion proteins other than tumour necrosis alpha (TNF-α) inhibitors, including therapeutics modulating T-cell-mediated pathologies (muromonab, abatacept, belatacept, ipilimumab, basiliximab, daclizumab), inducing lymphopenia (alemtuzumab), depleting CD20+ B cells (rituximab) and interfering with various targets (anakinra, natalizumab, blodalumab, ixekizumab and others) with a focus on children, and to provide a framework of evaluating the risk for IFIs in this population...

OBJECTIVE: With anorexia nervosa (AN) having various presentations, attention has been directed towards particularly durable forms of the condition in both research and clinical contexts. A major hindrance in terms of advancing the field is the inconsistent labeling and defining of this subgroup. This has two implications; first, the inconsistent recruitment of participants when researching this sample, and second, the misdiagnosing of patients who may or may not have a durable course of the disease...

Food security and safety are the major concern in ever expanding human population on the planet earth. Each and every year insect pests cause a serious damage in agricultural field that cost billions of dollars annually to farmers. The loss in term of productivity and high cost of chemical pesticides enhance the production cost. Irrespective use of chemical pesticides (such as Benzene hexachloride, Endosulfan, Aldicarb, and Fenobucarb) in agricultural field raised several types of environmental issues. Furthermore, continuous use of chemical pesticides creates a selective pressure which helps in emerging of resistance pest...

Acute kidney injury (AKI) is common in critically ill patients and associated with grim short- and long-term outcome. Although in the vast majority of cases AKI is multifactorial, with sepsis, shock and nephrotoxicity accounting for most episodes, specific causes of AKI are not uncommon. Despite remaining uncertainties regarding their prevalence in the ICU, prompt recognition of specific aetiologies of AKI is likely to ensure timely management, limit worsening of renal dysfunction, and ultimately limit renal and systemic consequences of AKI...

The worldwide prevalence of diabetes mellitus is expected to reach 439 million by 2030. Diabetes increases the risk for developing secondary complications such as nephropathy and cardiovascular disease, critical factors that dictate the survival rate of diabetes patients. Compelling evidence has indicated that the positive impact of fermentable carbohydrates in obesity-related diabetes is mediated by the production of short-chain fatty acids and the modulation of colonic microbiota. This review summarizes the potential implications of dietary resistant starch, a class of fermentable fiber, in glucose homeostasis and kidney health in obesity-associated diabetes and examines the mechanisms underlying the protective effect of resistant starch...

The mammalian gastrointestinal tract harbors trillions of commensal microorganisms, collectively known as the microbiota. The microbiota is a critical source of environmental stimuli and, thus, has a tremendous impact on the health of the host. The microbes within the microbiota regulate homeostasis within the gut, and any alteration in their composition can lead to disorders that include inflammatory bowel disease, allergy, autoimmune disease, diabetes, mental disorders, and cancer. Hence, restoration of the gut flora following changes or imbalance is imperative for the host...

Sepsis and trauma are both leading causes of death in the United States and represent major public health challenges. Murine models have largely been used in sepsis and trauma research to better understand the pathophysiological changes that occur after an insult and to develop potential life-saving therapeutic agents. Mice are favorable subjects for this type of research given the variety of readily available strains including inbred, outbred, and transgenic strains. In addition, they are relatively easy to maintain and have a high fecundity...
