Nandrolone decanoate (ND), an anabolic-androgenic steroid prohibited in collegiate and professional sports, is associated with detrimental cardiovascular effects through redox-dependent mechanisms. We previously observed that high-dose short-term ND administration (15 mg/kg for 2 weeks) did not induce left heart ventricular hypertrophy and, paradoxically, improved postischemic response, whereas chronic ND treatment (5 mg/kg twice a week for 10 weeks) significantly reduced the cardioprotective effect of postconditioning, with an increase in infarct size and a decrease in cardiac performance...

It is widely believed that the expanding burden of non-communicable diseases (NCDs) is in no small part the result of major macro-level determinants. We use a large amount of new data, to explore in particular the role played by urbanization - the process of the population shifting from rural to urban areas within countries - in affecting four important drivers of NCDs world-wide: diabetes prevalence, as well as average body mass index (BMI), total cholesterol level and systolic blood pressure. Urbanization is seen by many as a double-edged sword: while its beneficial economic effects are widely acknowledged, it is commonly alleged to produce adverse side effects for NCD-related health outcomes...

This commentary is to inform clinicians challenged with an increase in people seeking treatment for Substance Use Disorder (SUD), that the ninety percent revolving door, is, in part, due to post-withdrawal, untreated neurotoxicity. This impairment attenuates neurotransmitter signaling and compromises resting state functional connectivity, leading to unwanted sequelae including depression, sleep disturbances, sensation seeking, lack of satisfaction and impulsivity. Neuroimaging studies indicate that neurobiological recovery can take years...

AIM: Amlodipine, a calcium channel blocker became one of the most popular antihypertensive medications used in the paediatric population. This is mainly due to its long half-life making it easy to use as a single daily dose. Amlodipine is associated with common side effects like flushing, headache and dizziness. The incidence of amlodipine-related oedema was noted to be lower in the paediatric population compared to adults. We emphasise the importance of monitoring the development of oedema in patients treated with amlodipine...

Biological control is an important ecosystem service delivered by natural enemies. Together with breeding for plant defence, it constitutes one of the most promising alternatives to pesticides for controlling herbivores in sustainable crop production. Especially induced plant defences may be promising targets in plant breeding for resistance against arthropod pests. Because they are activated upon herbivore damage, costs only incur when defence is needed. Moreover, they can be more specific than constitutive defences...

The proliferation-promoting effect of neuropeptide Y (NPY) always functions in low-serum-cultured vascular smooth muscle cells (VSMCs), and the phenotypic switch of VSMCs is regulated by concentrations of serum. Whether the property of the NPY proliferative effect in VSMCs relies on phenotype of VSMCs is unclear. We aimed to explore the role of NPY on proliferation of different VSMC phenotypes in the pathogenesis of atherosclerosis. By stimulating A10 cells with 200 nM NPY in 0.5 or 10% serum, 3H-thymidine and 5-ethynyl-2'-deoxyuridine (EdU) and CCK8 measurements were used to detect VSMC proliferation...

The acute respiratory distress syndrome (ARDS) remains a serious clinical problem with the main treatment being supportive in the form of mechanical ventilation. However, mechanical ventilation can be a double edge sword, if set improperly can exacerbate the tissue damage caused by ARDS and is known as ventilator induced lung injury (VILI). In order to minimize VILI we must understand the pathophysiologic mechanisms of tissue damage at the alveolar level. In this Physiology in Medicine paper the dynamic physiology of alveolar inflation and deflation during mechanical ventilation will be reviewed...

APOBEC3 proteins are double-edged swords. They deaminate cytosine to uracil in single-stranded DNA and provide protection, as part of our innate immune system, against viruses and retrotransposons, but they are also involved in cancer evolution and development of drug resistance. We report a solution-state model of APOBEC3A interaction with its single-stranded DNA substrate obtained with the 'method of small changes'. This method compares pairwise the 2D 15N-1H NMR spectra of APOBEC3A bearing a deactivating mutation E72A in the presence of 36 slightly different DNA substrates...

OBJECTIVE: The existing literature has shown that war veterans' posttraumatic stress symptoms (PTSS) are associated with high levels of distress in their female partners. According to the literature, spouses' empathy for their spouses can be a risk factor for their own mental health. However, this subject has not been examined among veteran couples. The current study therefore investigated both the direct and moderating contribution of females' cognitive and affective empathy to their own PTSS and depression symptoms, above and beyond the preexisting traumatic events of the women's own lives and the veterans' PTSS...

The unfolded protein response (UPR) is a stress response conserved in eukaryotic organisms and activated by the accumulation of misfolded proteins in the endoplasmic reticulum (ER). Adverse environmental conditions disrupt protein folding in the ER and trigger the UPR. Recently, it was found that the UPR can be elicited in the course of plant development and defense. During vegetative plant development, the UPR is involved in normal root growth and development, the effect of which can be largely attributed to the influence of the UPR on plant hormone biology...

Hypomethylating agents (HMAs) have been widely used over the last decade, approved for use in myelodysplastic syndrome (MDS), chronic myelomonocytic leukemia (CMML) and acute myeloid leukemia (AML). The proposed central mechanism of action of HMAs, is the reversal of aberrant methylation in tumor cells, thus reactivating CpG-island promoters and leading to (re)expression of tumor suppressor genes. Recent investigations into the mode of action of azacitidine (AZA) and decitabine (DAC) have revealed new molecular mechanisms that impinge on tumor immunity via induction of an interferon response, through activation of endogenous retroviral elements (ERVs) that are normally epigenetically silenced...

Neuroplasticity, the brain's capacity to be shaped in response to environmental experience, has been claimed to resemble a double-edged sword - potentiating growth and healing when individuals are exposed to normative, benign or therapeutic environments on the one hand, mediating mental disorder development in those exposed to adversity, on the other. However, questions about the scope and limits of neuroplasticity and, especially, its clinical significance, remain unanswered.

The acute phase response has a crucial role in mounting the body's response to tissue injury. Excessive activation of the acute phase response is responsible for many complications that occur in orthopedic patients. Given that infection may be considered continuous tissue injury that persistently activates the acute phase response, children with musculoskeletal infections are at markedly increased risk for serious complications. Future strategies that modulate the acute phase response have the potential to improve treatment and prevent complications associated with musculoskeletal infection...

Survival in lung cancer patients is genetically determined. Single nucleotide polymorphisms (SNPs) in DNA repair genes are observed to play a critical role in survival as DNA repair itself can behave as double-edged sword. We aim to explore the association of DNA repair gene XRCC1 in survival and clinical outcomes for North Indian population. Blood sample from patients diagnosed with lung cancer was taken. DNA isolation and genotyping were performed for the SNPs of XRCC1 gene. Further, patients were followed up through telephonic conversation after every 2 months for 3 years...

The physiological functions of sphingosine 1-phosphate (S1P) and its pathological roles in various diseases are increasingly being elucidated. Particularly, a growing body of literature has implicated S1P in the pathogenesis of brain related disorders. With the deciphering of more intricate aspects of S1P signalling, there is also a need to reconsider the notion of S1P only as a determinant of cell survival and proliferation. Further the concept of 'S1P-ceramide' balance as the controlling switch of cellular fate and functions needs to be refined...

CONTEXT: Multiple endocrine neoplasia type 1 (MEN1) is a hereditary condition characterised by the predisposition to hyperplasia/tumours of endocrine glands. MEN1 related disease, moreover malignancy related to MEN1, is increasingly responsible for death in up to two-thirds of patients. Whilst patients undergo radiological and biochemical surveillance, current recommendations for radiological monitoring are based on non-prospective data with little consensus or evidence demonstrating improved outcome from this approach...

Adverse drug reactions (ADRs) represent a major health problem worldwide with high morbidity and mortality rates. ADRs are classified into type A (augmented) and type B (bizarre) ADRs with the former group being more common and the later less common but often severe and clinically more problematic due to their unpredictable nature and occurrence at any dose. Pediatric populations are especially vulnerable to ADRs due to the lack of data for this age group from the drug development process and because of the wide use of Off-label and unlicensed use of drugs...
