Cancer is one of the deadliest diseases in the world causing record number of mortalities in both developed and undeveloped countries. Despite a lot of advances and breakthroughs in the field of oncology still, it is very hard to diagnose and treat the cancers at early stages. Here in this review we analyze the potential of Ubiquitin-like containing PHD and Ring Finger domain 1 (UHRF1) as a universal biomarker for cancers. UHRF1 is an important epigenetic regulator maintaining DNA methylation and histone code in the cell. It is highly expressed in a variety of cancers and is a well-known oncogene that can disrupt the epigenetic code and override the senescence machinery. Many studies have validated UHRF1 as a powerful diagnostic and prognostic tool to differentially diagnose cancer, predict the therapeutic response and assess the risk of tumor progression and recurrence. Highly sensitive, non-invasive and cost effective approaches are therefore needed to assess the level of UHRF1 in patients, which can be deployed in diagnostic laboratories to detect cancer and monitor disease progression.

We evaluated the reliability of patient history and the effect of psyllium on symptoms and colorectal function in 12 patients with Parkinson's disease (PD) and constipation. In all but two, constipation anteceded the development of parkinsonian symptoms. A comparison with prospectively obtained stool diaries confirmed the patients' reported constipation in 7 of the 12 patients. Those patients with confirmed constipation had lower stool weights and reported more straining at stool. Measures of colonic and anorectal function were similar in those who were truly constipated and those who were not. Among those PD subjects with confirmed constipation, psyllium increased stool frequency and weight but did not alter colonic transit or anorectal function. We conclude that prospectively obtained stool diaries should be employed to confirm constipation in PD and that psyllium produces both subjective and objective improvements in constipation related to PD.

Background: Psyllium is widely used in the symptomatic therapy of constipation. Its effects on colonic function and their correlation with symptomatic response have not been defined. Methods: After a 4-week baseline, placebo, run-in phase, 22 subjects with idiopathic constipation confirmed by prospectively administered stool diaries were randomly assigned to receive either psyllium (5 g b.d., 11 patients) or placebo (11 patients) for 8 weeks, followed by another 4-week wash-out, placebo phase. A colon transit study and anorectal manometry were performed at the beginning and at the end of each study phase. Subjects recorded, in diaries, their daily stool frequency, difficulty with defecation and weekly stool weight. Results : Stool frequency increased significantly after 8
