Mechanism of 5-fluorouracil induced resistance and role of piperine and curcumin as chemo-sensitizers in colon cancer.

Among cancer-related deaths worldwide, colorectal cancer ranks second, accounting for 1.2% of deaths in those under 50 years and 0.6% of deaths in those between 50 and 54 years.

Doxorubicin-induced chemoresistance in Duke's type B colon adenocarcinoma cell line is aggravated in the presence of TGF-β2 through non-apoptotic cell death.

Background: The current challenge in clinical cancer treatment is chemoresistance. Colon cells have inherently higher xenobiotic transporters expression and hence can attain resistance rapidly. Increased levels of TGF-β2 expression in patients have been attributed to cancer progression, aggressiveness, and resistance.

A comprehensive review on time-tested anticancer drug doxorubicin.

Doxorubicin or Adriamycin, is one of the most widely used chemotherapeutic drug for treating a myriad of cancers. It induces cell death through multiple intracellular targets: reactive oxygen species generation, DNA-adduct formation, topoisomerase II inhibition, histone eviction, Ca and iron hemostasis regulation, and ceramide overproduction. Moreover, doxorubicin-treated dying cells undergo cellular modifications that enable neighboring dendritic cell activation and enhanced presentation of tumor antigen.

Writing Articles on Continuing Medical Education for Medical Journals.

Sharing of knowledge through Continuing Medical Education (CME) contribute immensely to professional development of skills in clinical medical practice. Thus, the writing of CME articles should adopt an approach that addresses the needs of the readers by attempting to fill gaps in their knowledge, skills, and ethics about clinical care. As such CME articles should be comprehensive and focused on specific areas.

Curcumin induces chemosensitization to doxorubicin in Duke's type B coloadenocarcinoma cell line.

Cancer cells require higher levels of ATP for their sustained growth, proliferation, and chemoresistance. Mitochondrial matrix protein, C1qbp is upregulated in colon cancer cell lines. It protects the mitochondria from oxidative stress, by inhibiting the Membrane Permeability Transition (MPT) pore and providing uninterrupted synthesis of ATP.

Curcumin induced apoptosis is mediated through oxidative stress in mutated p53 and wild type p53 colon adenocarcinoma cell lines.

Curcumin has anti-oxidant, anti-cancer and anti-carcinogen property. Our laboratory had previously reported that, curcumin treatment induces reactive oxygen species (ROS) generation in HT-29 cell line, an effect contradictory to its anti-oxidant property. This study evaluates the role of p53 in curcumin mediated ROS generation and cell death.

Cichorium intybus attenuates Streptozotocin-induced pancreatic β-cell damage by inhibiting NF-κB activation and oxidative stress.

The aqueous extract of Cichorium intybus (CIE) leaves have shown the properties of protecting against pancreatic β-cell damage by streptozotocin (STZ), but the molecular mechanisms of its protection are not completely elucidated yet. Our current study focuses on elucidating the mechanisms of these preventive effects of CIE in MIN6 cells and an in-vivo model of Wistar rats. CIE offers protection against STZ in MIN6 cells by reducing the pro-oxidants and increasing the activity of the antioxidant enzymes.

Vanillin extracted from Proso and Barnyard millets induce apoptotic cell death in HT-29 human colon cancer cell line.

In the present study, we hypothesized that the active compound extracted from Proso and Barnyard millets inhibits cell proliferation and apoptosis induction in colon cancer cell line. The bioactive compounds from these millets were purified by supercritical fluid extraction and their structure was elucidated using spectroscopic methods. Extracted bioactive components from these millets were similar in chemical structure to the phenolic aldehyde-Vanillin [4-Hydroxy-3-methoxybenzaldehyde].

Introduction: The aim of this systematic review is to compare the vaginal erosion rates in different synthetic materials used in suburethral slings in Tension Free Vaginal Tape (TVT-O /TOT) procedures in management of female stress urinary incontinence.

Methods: PRISMA 2009 framework was adopted for study design. Scholarly literature search was done using MEDLINE, EMBASE, the Cochrane Library and Clinical Trials.

Curcumin induces apoptosis and cell cycle arrest via the activation of reactive oxygen species-independent mitochondrial apoptotic pathway in Smad4 and p53 mutated colon adenocarcinoma HT29 cells.

Curcumin is a natural dietary polyphenol compound that has various pharmacological activities such as antiproliferative and cancer-preventive activities on tumor cells. Indeed, the role reactive oxygen species (ROS) generated by curcumin on cell death and cell proliferation inhibition in colon cancer is poorly understood. In the present study, we hypothesized that curcumin-induced ROS may promote apoptosis and cell cycle arrest in colon cancer.

Views of faculty members in a medical school with regards to error disclosure and reporting to parents and/or higher authorities.

Background: Little is known about the views of faculty members who train medical students concerning open disclosure.

Objectives: The objectives of this study were to determine the views of faculty in a medical school on: 1 what constitutes a medical error and the severity of such an error in relation to medication use or diagnosis; 2 information giving following such an adverse event, based on severity; and 3 acknowledgement of responsibility, remedial action, compensation, disciplinary action, legal action, and reporting to a higher body in relation to such adverse event.

Methods: We adapted and contextualized a questionnaire developed from a previous study.

Curcumin inhibits growth potential by G1 cell cycle arrest and induces apoptosis in p53-mutated COLO 320DM human colon adenocarcinoma cells.

Curcumin, a natural polyphenolic compound and it is isolated from the rhizome of Curcuma longa, have been reported to possess anticancer effect against stage I and II colon cancer. However, the effect of curcumin on colon cancer at Dukes' type C metastatic stage III remains still unclear. In the present study, we have investigated the anticancer effects of curcumin on p53 mutated COLO 320DM human colon adenocarcinoma cells derived from Dukes' type C metastatic stage.

The objectives of this study were to determine: (1) the perception of parents regarding the severity of medical error in relation to medication use or diagnosis; (2) the preference of parents for information following the medical error and its relation to severity; and (3) the preference of parents with regards to disciplinary action, reporting, and legal action.

Methods: We translated and contextualised a questionnaire developed from a previous study.

Cathepsin-B-mediated cleavage of Disabled-2 regulates TGF-β-induced autophagy.

Transforming growth factor-β (TGF-β) induces the expression of Disabled-2 (Dab2), an endocytic adaptor and tumour suppressor, concomitant with the induction of an epithelial-mesenchymal transition (EMT) in mammary epithelial cells. Here we show that following TGF-β-mediated EMT, sustained TGF-β treatment leads to proteolytic degradation of Dab2 by cathepsin B (CTSB), loss of the mesenchymal phenotype and induction of autophagy. CTSB inhibition or expression of a CTSB-resistant Dab2 mutant maintains Dab2 expression and shifts long-term TGF-β-treated cells from autophagy to apoptosis.

Molecular mechanism of TGF-β signaling pathway in colon carcinogenesis and status of curcumin as chemopreventive strategy.

Colon cancer is one of the third most common cancer in man, the second most common cancer in women worldwide, and the second leading cause of mortality in the USA. There are a number of molecular pathways that have been implicated in colon carcinogenesis, including TGF-β/Smad signaling pathway. TGF-β (transforming growth factor-beta) signaling pathway has the potential to regulate various biological processes including cell growth, differentiation, apoptosis, extracellular matrix modeling, and immune response.

Concepts in the management of the overactive bladder in women.

The 'overactive bladder' is a common problem affecting the elderly female population especially after the menopause. Urgency with or without urge incontinence accompanied by frequency of micturition and nocturia are presenting symptoms. The diagnosis is established after excluding other diseases of the lower urinary tract which have similar presenting features.

Zinc protects against indomethacin-induced damage in the rat small intestine.

The clinical utility of nonsteroidal anti-inflammatory drugs (NSAIDs) is often limited by the adverse effects that they produce in the small intestine. Alterations in the composition and functions of the glycocalyx and brush border membranes of the rat small intestine have been shown to occur in response to indomethacin, an NSAID often used in the study of adverse effects of these drugs. The micronutrient, zinc, has been documented to have cytoprotective effects in the gastrointestinal tract.

Activation of phospholipase A2 is involved in indomethacin-induced damage in Caco-2 cells.

Nonsteroidal anti-inflammatory drugs (NSAIDs), widely used in clinical practice, cause adverse effects in the gastrointestinal tract. These effects have been attributed to mechanisms such as drug-induced cyclooxygenase inhibition, oxidative stress, mitochondrial dysfunction and changes in cell membrane lipids. Our previous study showed that indomethacin (an NSAID commonly used in toxicity studies) caused activation of cytosolic phospholipase A(2) (cPLA(2)) in the rat small intestine.
