Article Abstract
Background And Aims: Zinc has been found to be low in chronic hepatitis patients. Its level was correlated with response to Interferon/ribavirin therapy in patients infected with hepatitis C genotype 1. In Egypt, inexpensive predictors to treatment response in Hepatitis C genotype 4 infected patients are desperately needed. We aim to explore if pretreatment zinc serum levels correlate with response to pegylated- interferon and ribavirin therapy in Egyptian patients.
Methods: This is an observational prospective study where 57 treatment naive hepatitis C genotype 4 infected patients that were Hepatitis B and Human Immunodeficiency virus negative were recruited in a hospital setting. The study was performed from October 2010 till June 2012. Patients had Liver biopsy and basic biochemical profiles were performed pretreatment for all patients. Treatment consisted of 48 weeks of pegylated-interferon-alpha2a and ribavirin therapy. Blood samples were withdrawn from 21 healthy subjects to compare zinc levels and other biochemical markers. Patients were followed up to 72 weeks.
Results: Pretreatment serum zinc levels were significantly lower in hepatitis C infected patients compared to healthy volunteers (p < 0.05). Moreover, zinc levels correlated to sustained virological response in treated patients (p = 0.00).
Conclusion: Serum zinc levels can be used as an inexpensive predictor to effective Pegylated-interferon/ribavirin therapy in Egyptian patients infected with Hepatitic C genotype 4.

Different sources and dosages of zinc oxide and copper influence growth performance and intestinal health of post-weaning piglets.

In pig production, weaning is a critical period where piglets face several environmental stressors. This transition leads to a significant growth reduction and can result in digestive disorders, including diarrhea. To formulate a feed that meets zinc (Zn) and copper (Cu) requirements during the weaning period while minimizing their release into the environment, it became evident that a more bioavailable micro-mineral supplement is necessary.

ObjectiveTo investigate the effects of zinc concentration on palatal development in fetal mice and its association with the aryl hydrocarbon receptor (AhR) signaling pathway.MethodsPregnant C57BL/6J mice were fed diets with varying zinc concentrations and randomly divided into a zinc-rich (ZR) group, a normal-zinc (NZ) group, and a zinc-deficient (ZD) group. Embryonic development was observed, and the expression levels of AhR signaling pathway-related factors were examined.

Electrochemical CO reduction reaction (CORR) has emerged as a key negative-emission technology, yet its industrial adoption hinges on cathode catalysts that deliver high selectivity and production rates at low cost. Herein, we reported a facile hydrothermal route to synthesize different scales of ZnOHF ultrathin nanowires with hybridized ZnO/ZnOHF heterointerfaces, where the 40 nm variant (NW-ZnOHF) showed a high FE of 93 % and a of -17.2 mA/cm at -1.

Copper (Cu) supplementation is essential in pig nutrition; however, its effects on performance, trace element accumulation in edible tissues, and environmental excretion require careful evaluation. In the present study a total of 24 male, castrated fattening pigs of two different hybrid mast lines (11 weeks of age) were divided according to their initial body weight (25.8 ± 3.

Background: Colorectal cancer (CRC) is common and deadly, often leading to metastasis, challenging treatment, and poor outcomes. Understanding its molecular basis is crucial for developing effective therapies.
Aims: This study aimed to investigate the role of Myosin Heavy Chain 11 (MYH11) in CRC progression, especially its effects on epithelial-mesenchymal transition (EMT) and cell behavior, and to explore its potential regulation by the EMT transcription factor zinc finger E-box binding homeobox 1 (ZEB1).
