ABSTRACT
The elemental analysis of packed food items which is collected in Debre Tabor markets, Ethiopia namely Pasta, Macaroni, cookies, biscuit, wheat bread, white teff injera, Red teff injera, barley so, barleycorn and maiz bread samples were carried out using EDX spectrometer. An X-ray beam was used to excite each sample and spectra were recorded with a high-resolution Si(Li) detector. The data analysis was carried out by software. Trace elements P, K, Na, Cl, Mg, Ca, Fe, Al and Zn were estimated, and elemental concentrations were determined. To get the exact results of the present study the analysis repeats three times.
ABSTRACT
Hodgson's bats are critically endangered in South Korea. This study analyzed the concentrations of elements in liver, kidney, and intestine tissues from a Hodgson's bat found dead in the wild. The concentrations of essential elements followed the order Fe > Zn > Cu >Mn > Se in the three tissues. Hg was detected at the highest concentrations among the non-essential elements analyzed in the liver and kidney tissues, while As was the most highly concentrated non-essential element in the intestine. To the best of our knowledge, this is the first study of tissue element concentrations in Hodgson's bats.

This study presents a preliminary data of occurrence of elemental concentration in medicinal plants i.e Apium graveolens (seed), Sida cordifolia (root), Solanum surattense (whole plant), Tribulus terrestris(fruit) and Withania somnifera (root) used in Ayurveda, using Atomic absorption spectrometer (AAS) following standard procedures. The elemental concentration i.e. Mn, Na, K, Cl, Ca, Cr, Co, Cu, Fe, Pb, Zn, Ni, Cd and Hg were found in various proportions. The data obtained from the study can be used to evaluate the potentiality of these plants in their used for Ayurvedic drugs.
ABSTRACT
Medical quality management is the core of hospital management.Concerning how to build the improving long-term mechanism of modem medical quality,the article is guided with the theory of modern medical quality management,and tested with the reform of medical quality management about one hospital.It puts forward 10 essential elements on how to construct the long-term mechanism on improving the medical quality,which is based on consulting all kinds of experts.Namely,“qualifications,responsibilities,complete path,reverence for life,reverence for integrity,reverence for rules,value on evaluation,value on case history,value on sum-up,value on teamwork”.Then it will take active effect on hospital workers and hospital managers in strengthening medical quality control,and improve the medical quality persistently.
ABSTRACT
Proper intake of dietary nutrients is considered crucial for preventing the initiation of events leading to the development of carcinoma. Many dietary compounds have been considered to contribute in cancer prevention including zinc, which plays a pivotal role in host defense against the initiation and promotion of several malignancies. Zinc is an essential element that is integral to many proteins and transcription factors which regulate key cellular functions such as the response to oxidative stress, DNA replication, DNA damage repair, cell cycle progression, and apoptosis. Zinc has been ascribed roles in the metabolism and interaction of malignant cells, particularly in apoptosis. Zinc is involved in structural stabilization and activation of the p53 that appears to be an important component of the apoptotic process and also in activation of certain members of the caspase family of proteases. Zinc exerts a positive beneficial effect against chemically induced preneoplastic progression in rats and provides an effective dietary chemopreventive approach to disease in vulnerable section of population with family history of carcinoma. The present review provides an insight into the research conducted on animals as well as on human subjects for providing the concept that zinc deficiency is an important factor in the development and progression of malignancy and that zinc could be efficacious in the prevention and treatment of several cancers viz., colon, pancreas, oesophageal and head and neck. However, it needs further exploration with regard to other definitive bioassays including protein expression and documentation of specific molecular markers to establish the exact mechanism for zinc-mediated cancer chemoprevention. Preclinical trials need to investigate the genetic and epigenetic pathways of chemoprevention by zinc.
