Bone cells secrete fibroblast growth factor 23 (FGF23), a hormone that inhibits the synthesis of active vitamin D (1,25(OH)2D3) and induces phosphate excretion in the kidney. ML162 Peroxidases inhibitor In addition, it exerts paracrine effects on other cells including hepatocytes, cardiomyocytes, and immune cells. The production of FGF23 is controlled by different factors including parathyroid hormone, 1,25(OH)2D3, alimentary phosphate, insulin, inflammation, and AMP-dependent kinase (AMPK) regulation of store-operated Ca2+ entry (SOCE). Peroxisome proliferator-activated receptor α (PPARα) is a transcription factor with anti-inflammatory properties regulating lipid metabolism. Fibrates, PPARα agonists, are used in the treatment of dyslipidemia and activate AMPK. Here, we tested whether PPARα is a regulator of FGF23. Fgf23 gene expression was analyzed in UMR106 rat osteoblast-like cells by qRT-PCR, AMPK phosphorylation by Western blotting, and SOCE assessed by fluorescence optics. PPARα agonists fenofibrate and WY-14643 suppressed, whereas PPARα antagonist GW6471 and siRNA-mediated knockdown of PPARα induced Fgf23 gene expression. Fenofibrate induced AMPK activity in UMR106 cells and lowered SOCE. AMPK inhibitor compound C abrogated the PPARα effect on FGF23 in large part. Silencing of Orai-1 resulted in failure of PPARα to significantly influence Fgf23 expression. Taken together, PPARα is a potent regulator of FGF23. PPARα agonists down-regulate FGF23 formation at least in part through AMPK-mediated suppression of SOCE.BACKGROUND Type-II Diabetes Mellitus (TII-DM) is the most common endocrine disorder in people who are over 65 years of age. It leads to a decrease in muscle strength and impaired muscle coordination. Ageing and weakness cause swallowing difficulty (SD). OBJECTIVE The aim of this study was to evaluate the relationship between duration of disease, SD and swallowing anxiety (SA) in TII-DM patients. STUDY DESIGN Prospective case-control study. METHODS A total of 103 elderly individuals (74 females and 29 males) participated in this study. Fifty-two elderly patients (aged 70.27 ± 4.65 years) had a TII-DM and the duration of DM was 11.32 ± 10.03 years (minimum 0-40 years). Fifty-one patients without diabetes mellitus (69.35 ± 3.58 years) were included in the control group. SD was determined using the EAT-10 Questionnaire. SA was evaluated with the Swallowing Anxiety Scale developed in the Turkish population. Handgrip strength was evaluated with a Jamar dynamometer on the dominant side. RESULTS There was a significaght to be helpful in the prevention or early rehabilitation of swallowing disorders.PURPOSE Recent reports indicate an increase in the prevalence of Warthin's tumours (adenolymphoma) with percentages which exceed that of pleomorphic adenomas (PA) in the same registries. The purpose of this study is to analyse a large cohort of benign parotid tumours in relation to various demographic and other patients' characteristics that might affect their incidence. METHODS A retrospective review of prospective collected data was performed on all patients who have been operated for a parotid mass in the last 5 years. A total of 474 patients with benign lesion were included in the study. Age, gender, smoking status, histological diagnosis, site of lesion, and size of tumour were recorded. RESULTS Warthin's tumours were the most common benign lesions, found in 201 (42.4%) parotic glands followed by pleomorphic adenomas found in 138 (29.1%) of these surgical cases. Patients with WT had a mean age of 61.6 years instead of 52 years for PA patients (t = 6.589, p  less then  0.001). The vast majority (93%) of patients with WT had a current or previous history of smoking compared with 47% of PA patients (p = 0.001). There was a male predominance regarding WT with a malefemale (MF) ratio of 2.31, whereas the corresponding ratio of PA was 11.4. CONCLUSIONS This study confirms the increased regional prevalence of WT reported in studies mainly carried out in central Europe. This could affect future management of WT, which remains largely controversial due to the extremely low malignant potential reported, concurrently with its higher rates of multiplicity and recurrence, as well as the moderately accurate results of FNA biopsies.BACKGROUND People have the need to find explanations for the events that occur in their lives. This is especially true when it comes to experiences that impact a person's entire existence and endanger their self-esteem and sense of identity. Chronic pain is one such experience. The search for the cause behind such pain is primarily motivated by the expectation that once the cause of the pain has been identified, an effective pain-alleviating therapy should ensue. Due to the numerous advances in the last several decades towards understanding the fundamental mechanisms governing the origins and processing as well as the treatment of pain, such expectations towards medicine can frequently be met; however, in many cases the experiences of chronic pain remain difficult to explain and, above all, very difficult to manage. GOAL In this article the authors aim to show that it is important to avoid fixation on the question of why, especially with people suffering from chronic pain. METHOD The article starts by describing how an exclusive orientation towards cause-effect-relationship in the medical context can also lead to negative consequences. Through recourse to the central theses of the existentialist philosopher Albert Camus, the meaning of the what for perspective is then discussed. Finally, with the example of a case study, it is illustrated how this change of perspective can result within the framework of a therapeutic treatment. RESULTS The following changes in perspective are recommended the search for the past-centered why should make way for the future-oriented quest for the what for of continuing to live a life with chronic pain.PURPOSE Anti-inflammatory and barrier-protective properties have been attributed to proanthocyanidins in the context of intestinal dysfunction, however little information is available about the impact of these phytochemicals on intestinal barrier integrity and immune response in the human. Here we assessed the putative protective properties of a grape-seed proanthocyanidin extract (GSPE) against dextran sodium sulfate (DSS)-induced acute dysfunction of the human colon in an Ussing chamber system. METHODS Human proximal and distal colon tissues from colectomized patients were submitted ex vivo for a 30-min preventive GSPE treatment (50 or 200 µg mL-1) followed by 1-h incubation with DSS (12% w v-1). Transepithelial electrical resistance (TEER), permeation of a fluorescently-labeled dextran (FD4) and proinflammatory cytokine release [tumor necrosis factor (TNF)-α and interleukin (IL)-1β] of colonic tissues were determined. RESULTS DSS reduced TEER (45-52%) in both the proximal and distal colon; however, significant increments in FD4 permeation (fourfold) and TNF-α release (61%) were observed only in the proximal colon.
