Label-free analysis of mononuclear human blood cells in microfluidic flow by coherent imaging tools.

The investigation of the physical properties of peripheral blood mononuclear cells (PBMC) is of great relevance, as they play a key role in regulating human body health. Here we report the possibility to characterize human PBMC in their physiological conditions in a microfluidic-based measurement system. A viscoelastic polymer solution is adopted for 3D alignment of individual cells inflow. An optical signature (OS) acquisition of each flowing cell is performed using a wide angle light scattering apparatus. Besides, a quantitative phase imaging (QPI) holographic system is employed with the aim (i) to check the position in flow of individual cells using a holographic 3D cell tracking method; and (ii) to estimate their 3D morphometric features, such as their refractive index (RI). Results obtained by combining OS and QPI have been compared with literature values, showing good agreement. The results confirm the possibility to obtain sub-micrometric details of physical cell properties in microfluidic flow, avoiding chemical staining or fluorescent labelling.

A Chaotic Maps-Based Authentication Scheme for Wireless Body Area Networks

As a technology of monitoring and recording human body health signals, wireless body area networks (WBANs) play an increasingly important role in the field of healthcare. Inspired by the semigroup property of Chebyshev maps, we designed a novel chaotic maps-based authentication scheme for wireless body area networks. The study aims to avoid modular exponential computation or scalar multiplication on an elliptic curve and reduce the need for time-consuming. Compared with the previous schemes, our scheme not only enjoys more security features but also has reduced computational cost of client and application provider. Moreover, we present the security model for our scheme, demonstrate the validity of the protocol by the BAN (Burrows, Abadi, and Needham) logic in detail, and analyze the software implementation method of Chebyshev polynomial.

Bio-Functional Cu Containing Biomaterials: a New Way to Enhance Bio-Adaption of Biomaterials

Although being an essential trace element required for human body health, Cu has long been seriously considered toxic when its amount exceeds certain limitation, which significantly limited the wide application of Cu in biomaterials. However, more and more bio-functions and benefits of Cu were found and confirmed, attracting the attention from biomaterials researchers in recent years. People have tried to immobilize Cu into biomaterials by various ways, in order to develop novel bio-functional Cu containing biomaterials with better bio-adaptions, and several different bio-functions of them have been demonstrated. This paper makes a review of the development of novel bio-functional Cu containing biomaterials, and focuses on their unique roles in enhancing bio-adaption of biomedical materials, including antibacterial performance, stimulating angiogenesis, promoting osteogenesis and inhibition of in-stent restenosis, aiming at proposing a prospective development direction for biomedical materials with better bio-adaptions.

JUSTIFICATION OF CALCIUM LACTATE USAGE IN BREAD MAKING

Overall and reproductive health of nation becomes a crucial issue at the beginning of the XXI century in Russia. Together with unsatisfactory ecological environment and huge emotional load, nutrition issue, which becomes a burning point on today's agenda, is a factor deteriorating the RF nation's health: the food market is flooded with unsatisfactory local and imported food products. The share of food with low percentage of vitamins and micro elements has significantly increased. These result in worsening human body's health, in decreasing immunity and vitality, and in premature aging.

Diversity and evolution of the primate skin microbiome.

Skin microbes play a role in human body odour, health and disease. Compared with gut microbes, we know little about the changes in the composition of skin microbes in response to evolutionary changes in hosts, or more recent behavioural and cultural changes in humans. No studies have used sequence-based approaches to consider the skin microbe communities of gorillas and chimpanzees, for example. Comparison of the microbial associates of non-human primates with those of humans offers unique insights into both the ancient and modern features of our skin-associated microbes. Here we describe the microbes found on the skin of humans, chimpanzees, gorillas, rhesus macaques and baboons. We focus on the bacterial and archaeal residents in the axilla using high-throughput sequencing of the 16S rRNA gene. We find that human skin microbial communities are unique relative to those of other primates, in terms of both their diversity and their composition. These differences appear to reflect both ancient shifts during millions of years of primate evolution and more recent changes due to modern hygiene.

The use of tractors is indispensable and essential to the agriculture. However, despite being efficient machines, tractors may fail in their projects, leading to the appearance of vibrations in different parts of their structure. Many studies show that the daily exposure to high levels of vibration, these are a risk factor for the health of the whole human body. In view of that, the purpose of this study was to evaluate the vibration levels in two static tractors, with the following specifications: Tractor (1) without cab, 4×2 model TDA manufactured in 1997, 89 kW of nominal engine power; tractor (2) with cab 4×2 model TDA manufactured in 2014, 65 kW of nominal engine power. The rotations were determined by the manufacturer´s manual of both tractors. The vibrations were measured by the accelerometer, properly calibrated. Data were collected in the Test Center of Machines and Agroforestry tires - belonging to the Faculty of Agricultural Sciences, UNESP Botucatu - SP. The accelerometer was fixed at different points of the tractors, collecting their overall structural vibration. For the conditions that were conducted this study, it can be concluded that the tractor vibrations tend to increase according to the addition of the use of time of the tractors. The engine is a great source of vibration as noted in both tractors, as soon the vibration in steer wheel control system is a concern, due to the fact that is a place where the operator maintain constant contact, however the vibrations levels in tractor with cabin were lower than tractors without cabin.  The cabin is an important equipment in machines protecting the operator from the vibrations, besides the weather roughness, dust and possible objects that could be launched during the operations.    Key words: Vibration, ergonomics, working environment, operator. &nbsp

Evaluation of toxicological risk of foodstuffs contaminated with heavy metals in Swat, Pakistan

This study aimed to assess the concentrations of heavy metals such as cadmium (Cd), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn) in the available foodstuffs (crops, milk and water), their bioaccumulation in human body and potential human health risks in Swat valley, northern Pakistan. Heavy metal concentrations in foodstuffs and human blood (adults (18-above) and children (1–12 years)) were analyzed using atomic absorption spectrometer. The results revealed high level of Mn in foodstuffs followed by Cr>Cu>Zn>Ni>Cd>Pb, which significantly increased the levels of heavy metals in the adult׳s blood as compared to that of children in the order of Cr>Zn>Mn>Ni>Pb>Cu>Cd. Principal component analysis showed that selected foodstuffs were the possible sources of metal contamination in human blood, while correlation analysis revealed that the concentrations of Cr, Cu, Mn, Ni, Pb and Zn in foodstuffs significantly correlated with that in human blood. Moreover, risk assessments for individual metals via foodstuffs were found within safe limits, except for Cd (HQ>1); Whereas, for aggregate multiple metals the risk was calculated as 3.97E+00 (HI>1), in which water and milk were perceived as the greater contributors (81 percent) to HI; while fruits, grains and vegetables contributed 5 percent each, and pulses 4 percent.

The rapid selecting of precursor ions and product ions of thirty-four kinds of pesticide for content determination by GC–EI/MS/MS

Pesticide residues caused great threat to human body health, and all countries protected the health of human body by specifying its upper limit. However, pesticide residues were generally very low, similar to trace analysis and as low as millionth or less, the content determination of pesticide residues was a troublesome problem. With the application and promotion of tandem mass spectrometry, it was able to do trace analysis. GC–EI/MS/MS was a common method for the determination of pesticide residues. The multiple reaction monitoring (MRM) mode was the most common quantitative method used in GC–EI/MS/MS. It has the characteristics of high sensitivity, good reproducibility, high accuracy, strong anti-interference and high ion flux. Multiple-twin precursor ions, product ions and collision energy of thirty-four pesticides were provided for MRM. It could play an important role in developing MRM method for the quantifying of 34 kinds of pesticide. Meanwhile, the development of MRM method for the quantifying of other compounds could also refer to this paper.

Research and Manufacture of Tea-Cigarette

Through a qualitative analysis of the combustion outcomes, almost no aldehydes have produced after the burning of the tea-leaves. However, the aldehydes can be produced obviously after the burning of tobacco. When tea-leaves were mixed with tobacco, the harmful substances can be drastically reduced in the burning, such as nicotine. Also, the difficulty of smoking will be intensified with the increase of the content of tea-leaves. People can feel the difficulty of smoking when the content of tea-leaves is over 50%, the feeling can be obviously when the content of tea-leaves is over 60%. It is necessary to control the content of tea-leaves less than 40% to ensure the health of human body.

In the era of modernization, evidence based Ayurveda is a hot topic for clinician, student of Ayurveda medicine, planners, patient and public in large. Ayurveda is the science of life defines the trinity of life as body, mind and spiritual awareness which are associated with health and illness of human body [1]. The use of Ayurvedic medicines has become accepted in other countries as well. For example, according to the 2007 National Health Interview Survey, more than 200,000 US adults had used Ayurvedic medicine in 2006 alone [2]. Govt of India has emerged all alternative medicines under one umbrellathe department of AYUSH, where the Ayurveda, Yoga, Unani, Sidha and Homeopathy are flourishing well [3].

Attitudes and knowledge towards reproductive health and sexual maturation among secondary school students in Vojvodina

Adolescence is a period in which young people are exposed to various physiological disorders, diseases and social consequences of risky behavior. Sudden changes in society leading to increased poverty, changes of values and increased crime rate can all cause risky behavior among young people. The aim of the study was to establish the attitudes and knowledge of secondary school students in Vojvodina related to the human body, physiological processes, sexual maturation and reproductive health. The study also focused on students' attitudes towards sexual intercourse and to what extent the topics related to reproductive health are present in the school curriculum. In this investigation we used data obtained in a recent research on second, third and fourth-year secondary students in some municipalities of Vojvodina in 2012 and 2013. The students were examined in the municipalities of Ruma, Senta, Čoka, Kanjiža and Subotica. We applied the method of survey. The questions were both open and closed, and divided into four groups: knowledge on the human body and sexual organs, information on sexual maturation and reproductive health, attitudes towards sexual intercourse and students' views on the content of reproductive health issues in the curriculum. The adolescents do not know enough about the human body and the basic physiological processes and show insufficient awareness of the importance of using contraception to preserve their reproductive health. Most of the students express a positive opinion of introducing a special subject into the curriculum that would deal with issues related to reproductive health. The obtained data are consistent with other previous studies in Serbia, suggesting that nothing has changed in this segment of our medical culture. The results suggest that young people need sexual education that corresponds to their age and needs, in order to be able to increase their knowledge and improve skills that can help them maintain their health.
