INTRODUCTION: Positive psychotic experiences are associated with increased rate of white noise speech illusions in patients and their relatives. However, findings have been conflicting to what degree speech illusions are associated with subclinical expression of psychosis in the general population. The aim of this study was to investigate the link between speech illusions and positive psychotic experiences in a general population sample. In addition, the hypothesis that speech illusions are on the pathway from known risk factors for psychosis (childhood adversity and recent life events) to subthreshold expression of psychosis, was examined...

Jsrg Saran, Jagadish R Padubidri
The concept of brain death has been a very intriguing topic and has taken many forms over the years. Brain stem death is a complex state of inactivity defined by the loss of reflexes of the pathways that pass through the brain stem, the 'shaft' of the brain which links the spinal cord to the cerebral cortex and the cerebellum where there is apnoea, loss of eye movement and pain sensation. There are many criteria, based on which a person can be said to be brain dead. The best recognised of these are the Harvard, Minnesota and Philadelphia criteria...

Oxidative stress contributes substantially to podocyte injury, which plays an important role in the development of diabetic kidney disease. The mechanism of hyperglycemia-induced oxidative stress in podocytes is not fully understood. Glucose-6-phosphate dehydrogenase (G6PD) is critical in maintaining NADPH, which is an important cofactor for the antioxidant system. Here, we hypothesized that high glucose induced ubiquitination and degradation of G6PD, which injured podocytes by reactive oxygen species (ROS) accumulation...

The objective of this study was to investigate theoretically the mechanisms underlying uric acid transport in the proximal tubule (PT) of rat kidneys, and their modulation by factors including Na+ , parathyroid hormone (PTH), Angiotensin II, and SGLT2 inhibitors. To that end, we incorporated the transport of uric acid and its conjugate anion urate in our mathematical model of water and solute transport in the rat PT. The model accounts for parallel urate reabsorption and secretion pathways on apical and basolateral membranes, and their coupling to lactate and alpha-ketoglutarate transport...

Silicosis is a well acknowledged occupational lung disorder with considerable negative impact on the patients' quality of life. Various signaling pathways have been reported to interplay in the pathogenesis of pulmonary fibro-proliferative disorders; of which, P-AKT/mTOR signaling pathway. The current study highlights the potential pulmonary protective effect of carvedilol; a non-selective α/β blocker against experimental silicosis-induced in rats by the intranasal installation of silica (50 mg/rat, 1 ml 0...

Although autologous human mesenchymal stem cells (hMSCs) are a promising source for regenerative stem cell therapy in chronic kidney disease (CKD), the barriers associated with pathophysiological conditions limit therapeutic applicability to patients. We confirmed that level of cellular prion protein (PrPC ) in serum was decreased and mitochondria function of CKD-derived hMSCs (CKD-hMSCs) was impaired in patients with CKD. We proved that treatment of CKD-hMSCs with tauroursodeoxycholic acid (TUDCA), a bile acid, enhanced the mitochondrial function of these cells through regulation of PINK1-PrPC -dependent pathway...

Long non-coding RNAs (LncRNAs) have been found to be associated with the biological behaviors of human cancers. LINC00152 is reported as an oncogene in many kinds of malignancies. However, the functions and mechanisms of LINC00152 involved in esophageal squamous cell carcinoma (ESCC) remain elusive. Our results revealed that LINC00152 expression was up-regulated in ESCC, and correlated with advanced TNM stage, lymph node metastasis, and poor prognosis of ESCC patients. Functionally, LINC00152 knockdown suppressed proliferation, decreased colony forming ability, and induced apoptosis in ESCC cells...

C-21 steroids displayed the activities of immunosuppressive, anti-inflammatory and anti-virus effects by the reports. However, its antitumor effects and molecular mechanism remain unclear. We previously isolated and identified a C-21 steroidal glycoside (BW18) from the root of Cynanchum atratum Bunge. This study was aimed to assess anti-leukemia activity and its underlying mechanism in K562 cells. MTT assay results showed that BW18 inhibited cell viability and proliferation of K562 cells. We also found that BW18 could induce S phase cell cycle arrest and apoptosis...

Changes in the nature and structure of healthcare pathways have implications for healthcare professionals' jurisdictional boundaries. The introduction of treatment focused BRCA1 and 2 genetic testing (TFGT) for newly diagnosed patients with breast cancer offers a contemporary example of pathway change brought about by technological advancements in gene testing and clinical evidence, and reflects the cultural shift towards genomics. Forming part of an ethnographically informed study of patient and practitioner experiences of TFGT at a UK teaching hospital, this paper focuses on the impact of a proposal to pilot a mainstreamed TFGT pathway on healthcare professionals' negotiations of professional jurisdiction...

REVIEW
Ida-Fong Ukor, Keith R Walley
Vasodilatory shock is the final common pathway for all forms of severe shock, with sepsis the most common primary etiology and the leading cause of critical illness-related mortality. The pathophysiology of this condition remains incompletely elucidated. Deficiency of the neuropeptide hormone vasopressin seems to play a significant role. The physiology of vasopressin and its interaction with the pathophysiology of vasodilatory shock are described in this review. A brief review of the major randomized controlled trials assessing the efficacy and safety of vasopressin and its analogs in this complex patient cohort is also provided...

REVIEW
Yue Leng, Erik S Musiek, Kun Hu, Francesco P Cappuccio, Kristine Yaffe
Dysfunction in 24-h circadian rhythms is a common occurrence in ageing adults; however, circadian rhythm disruptions are more severe in people with age-related neurodegenerative diseases, including Alzheimer's disease and related dementias, and Parkinson's disease. Manifestations of circadian rhythm disruptions differ according to the type and severity of neurodegenerative disease and, for some patients, occur before the onset of typical clinical symptoms of neurodegeneration. Evidence from preliminary studies suggest that circadian rhythm disruptions, in addition to being a symptom of neurodegeneration, might also be a potential risk factor for developing Alzheimer's disease and related dementias, and Parkinson's disease, although large, longitudinal studies are needed to confirm this relationship...
