Starting from the Developmental Origins of Health and Disease (DOHaD) hypotheses proposed by David Barker, namely fetal programming, in the past years, there is a growing evidence of the major role played by epigenetic factors during the intrauterine life and the perinatal period. Furthermore, it has been assessed that these factors can affect the health status in infancy and even in adulthood. In this review, we focus our attention on the fetal programming of the brain, analyzing the most recent literature concerning the epigenetic factors that can influence the development of neuropsychiatric disorders such as bipolar disorders, major depressive disorders, and schizophrenia...

Compromised protein folding capacity in the endoplasmic reticulum (ER) leads to a protein traffic jam that produces a toxic environment called ER stress. However, the ER smartly handles such a critical situation by activating a cascade of proteins responsible for sensing and responding to the noxious stimuli of accumulated proteins. The ER protein load is higher in secretory cells, such as liver hepatocytes, which are thus prone to stress-mediated toxicity and various diseases, including alcohol-induced liver injury, fatty liver disease, and viral hepatitis...

BACKGROUND: As one of the most popular expression systems, recombinant protein expression in Pichia pastoris relies on the AOX1 promoter (P AOX1 ) which is strongly induced by methanol. However, the toxic and inflammatory nature of methanol restricts its application, especially in edible and medical products. Therefore, constructing a novel methanol-free system becomes necessary. The kinases involved in P AOX1 activation or repression by different carbon sources may be promising targets...

The hexavalent chromium, Cr(VI), which is generated in the electroplating process, is toxic to most organisms and potentially harmful to human health. The method generally used for remediation of wastewater containing Cr(VI) employs chemicals with high toxicity. This work proposes an alternative technology for the treatment of these wastewaters, based on photochemical reduction of Cr(VI) by alcohols under radiation, which is environmentally sustainable and economically viable. Initially, a batch reactor in laboratory scale was used to determine the best experimental conditions and its specific reaction rate was calculated...

OBJECTIVE: Doxorubicin (DOX) is an effective anticancer drug but its clinical application is limited because it induces apoptosis in cardiomyocytes and leads to permanent degenerative cardiomyopathy and heart failure possibly due to oxidative stress. Recent studies showed that Capparis spinosa (C. spinose) exhibits potent antioxidant activity. So, in this study, we explored the protective effect of hydro-alcoholic extract of C. spinosa against DOX-induced cytotoxicity in H9c2 cells. MATERIALS AND METHODS: Cell viability was quantified by MTT assay...

Flutamide (FLT) is a non steroidal antiandrogenic drug used to treat prostate cancer. Its poor aqueous solubility and toxicity are the major hindrance for oral drug delivery. The nanoformulation of flutamide increases its aqueous solubility thereby improves the therapeutic efficacy of the chemodrug. Poly (vinyl alcohol) (PVA) coated flutamide nanoparticles (PVA FLT NPs) were formulated by nanoprecipitation method and characterized by DLS, TEM and FTIR. The nanoparticles were about 300nm size and spherical in shape...

Ethanol abuse is a serious public health problem that is associated with several stages of alcoholic liver disease (ALD) and a high incidence of morbidity and mortality. Alcoholic fatty liver disease (AFLD), the earliest stage of ALD, is a multifactorial injury that involves oxidative stress and disruptions of lipid metabolism. Although benign and reversible, no pharmacological treatments are available for this condition. In the present study, we induced AFLD in mice with 10% ethanol and a low-protein diet and then orally treated them with a hydroethanolic extract of Baccharis trimera (HEBT; 30 mg kg(-1))...

Increasingly, squamous cell carcinoma of the oropharynx (OPSCC) is attributable to transformation resulting from high-risk human papillomavirus (HPV) infection. Such cancers are significantly more responsive to treatment than traditional tobacco- and alcohol-associated squamous cell cancers of the head and neck. Conventional management with definitive chemoradiation, surgery and adjuvant radiation, or radiation given with altered fractionation schemes, while effective, incurs long-term morbidity that escalates with treatment intensity and significantly impairs quality of life...

5-Fluorouracil (5-FU) is the backbone of the chemotherapy regimens approved for treatment of many malignancies, especially colorectal cancer (CRC). The incidence of cardiotoxicity associated with 5-FU ranges between 1.5% to 18% and is most commonly manifested as anginal symptoms. Cardiomyopathy is very rarely reported with 5-FU and capecitabine. A 35-year-old Caucasian male with T3, N1, M0 rectal cancer after the initial neoadjuvant chemoradiation with 5FU/LV followed by surgical abdominoperineal resection (APR), began mFOLFOX6 in the adjuvant setting...

BACKGROUND Besides providing anesthesia for surgery, the anesthesiologist's role is to optimize the patient for surgery and for post-surgical recovery. This involves timely identification and treatment of medical comorbidities and abnormal laboratory values that could complicate the patient's perioperative course. There are several potential causes of anion and non-anion gap metabolic acidosis in surgical patients, most of which could profoundly affect a patient's surgical outcome. Thus, the presence of an acute acid-base disturbance requires a thorough workup, the results of which will influence the patient's anesthetic management...

Antimicrobial electrospun poly(vinyl alcohol) (PVA) nanofibers were synthesized by impregnating benzyl triethylammonium chloride (BTEAC) as an antimicrobial agent into PVA nanofibers. The BTEAC-PVA nanofibers were heat-methanol treated during the preparation for various tests. The BTEAC-PVA nanofibers became more hydrophilic than the PVA nanofibers due to incorporation of BTEAC. Through heat-methanol treatment, thermal property, crystallinity, and water stability of BTEAC-PVA nanofibers were improved considerably...
