  • Assessment of cytological atypia, AgNOR and nuclear area in epithelial cells of normal oral mucosa exposed to toombak and smoking

Abstract

The purpose of this study was to assess cellular proliferative activity of clinically healthy oral mucosal epithelial cells of toombak dippers and smokers by means of AgNOR counts and nuclear areas via nuclear morphometry. Smears were collected from normal-appearing mouth floor mucosa and tongue of 75 toombak dippers, 75 smokers and 50 non-tobacco users between the ages of 20 and 70 with a mean age of 36 years. AgNORs were counted in the first 50 well-fixed, nucleated squamous cells and nuclear areas were calculated via microscopic stage micrometer. Cytological atypia was ascertained in 6 tobacco users and could not be ascertained in non-tobacco users. Statistically mean AgNOR numbers per nucleus in the non-tobacco users (2.45±0.30) was lower than the toombak dippers (3.081±0.39, p<0.004), and the smokers (2.715±0.39, p<0.02), and mean nuclear areas of epithelial cells of toombak dippers (6.081±0.39, p<0.009) and smokers (5.68±10.08, p<0.01) was also significantly higher than non-smokers (5.39±9.4). The mean number of nuclei having more than 3 AgNORs was 28%, 19% and 7% in toombak dippers, smokers and non-tobacco users, respectively. These findings support the view that toombak dipping and smoking are severe risk factors for oral mucosal proliferative lesions and exfoliative cytology is valid for screening of oral mucosal lesions.

Key words: toombak, smoking, oral mucosa, AgNOR, nuclear area.

  • Rheological and quality characteristics of composite gluten-free dough and biscuits supplemented with fermented and unfermented Agaricus bisporus polysaccharide flour

In this study, functional, rheological and physicochemical characteristics were carried out for composite gluten-free (CGF) flours, dough and biscuits, respectively fortified with fermented and unfermented Agaricus bisporus polysaccharide (FABP and UABP) flours. Addition of both FABP flour and UABP flour improved functional properties, while addition of FABP flour decreased viscosity property. Incorporation of both polysaccharide flours in CGF biscuit dough revealed a significant increase in rheological moduli (G׳ and G’’) and a decrease in tan (δ). Supplementation of UABP flour increased thickness, whereas supplementation of FABP flour increased diameter and spread ratio. All CGF biscuit formulations exhibited lower fracture strength and hardness compared to the control. Furthermore, both UABP flour and FABP flour formulation (F3) contained the highest nutrients in terms of protein, dietary fibers, amino acids and minerals among the CGF biscuit formulations

  • A low-cost fuel selling machines using RFID and IoT technology

Technological development is growing rapidly
worldwide, so many machines, factories, and even homes use
these technologies .The target of this paper is to avoid Cars
congestion and long waiting in the queue of fuel pumps,
excessive employment. The commission is not available
financially. And lack of reliability in the sales system. The
automatic implementation of the technological systems is very
useful for the security and confidentiality of the mechanisms
and factories in particular with respect to access to devices and
the user authorized to carry out specific operations. In this
work, an automatic fuel selling machine system is designed
using the Radio Frequency Identification RFID device and The
Internet of Things technology. The designed system is
providing fast filling of fuel, ease in financial transactions, and
more secure by checking the rights of access to the device using
the RFID card read by the reader. In addition, the system
allows the possibility of monitoring the access to the fuel
station and offer a special graphical user interface to the
service provider.

  • Design of a New Model for Enhancement of the Performance of Nested Mobile Networks

Recently; Network Mobility (NEMO) turns into a vital necessity for IP systems. It guarantees stable web availability amid the system versatility. Internet Engineering Task Force- Request for Comment (IETF RFC 4889) discussed route optimization in nested mobile network as an overcome of some limitations. In this paper, new model has been proposed to enhance the performance of nested networks. Through the simulation in top-level of nested achieved 5% less end to end delay and 20% more throughput than NEMO BSP. In mid-level of nested achieved 10% less end to end delay and 18% more  throughput than NEMO BSP. Finally; in third-level of nested achieved 14% less end to end delay and 15% more throughput than NEMO BSP. All of this taking into consideration that there is just three level of nesting, so when the level of nesting increased results become efficacious. This model can classify as one of best proposed solution for nested mobile networks routing limitations and can be developed to reach optimal results by using more intelligent routers.
