Low Power Reversible Parallel Binary Adder/Subtractor

In recent years, Reversible Logic is becoming more and more prominent technology having its applications in Low Power CMOS, Quantum Computing, Nanotechnology, and Optical Computing. Reversibility plays an important role when energy efficient computations are considered. In this paper, Reversible eight-bit Parallel Binary Adder/Subtractor with Design I, Design II and Design III are proposed. In all the three design approaches, the full Adder and Subtractors are realized in a single unit as compared to only full Subtractor in the existing design. The performance analysis is verified using number reversible gates, Garbage input/outputs and Quantum Cost. It is observed that Reversible eight-bit Parallel Binary Adder/Subtractor with Design III is efficient compared to Design I, Design II and existing design.Comment: 12 pages,VLSICS Journa

Secured Smart Healthcare Monitoring System Based on Iot

Technology plays the major role in healthcare not only for sensory devices but also in communication, recording and display device. It is very important to monitor various medical parameters and post operational days. Hence the latest trend in Healthcare communication method using IOT is adapted. Internet of things serves as a catalyst for the healthcare and plays prominent role in wide range of healthcare applications. In this project the PIC18F46K22 microcontroller is used as a gateway to communicate to the various sensors such as temperature sensor and pulse oximeter sensor. The microcontroller picks up the sensor data and sends it to the network through Wi-Fi and hence provides real time monitoring of the health care parameters for doctors. The data can be accessed anytime by the doctor. The controller is also connected with buzzer to alert the caretaker about variation in sensor output. But the major issue in remote patient monitoring system is that the data as to be securely transmitted to the destination end and provision is made to allow only authorized user to access the data. The security issue is been addressed by transmitting the data through the password protected Wi-Fi module ESP8266 which will be encrypted by standard AES128 and the users/doctor can access the data by logging to the html webpage. At the time of extremity situation alert message is sent to the doctor through GSM module connected to the controller. Hence quick provisional medication can be easily done by this system. This system is efficient with low power consumption capability, easy setup, high performance and time to time response. DOI: 10.17762/ijritcc2321-8169.150712

Implementation and delivery of group consultations for young people with diabetes in socioeconomically deprived, ethnically diverse settings

BACKGROUND: Young people with diabetes experience poor clinical and psychosocial outcomes, and consider the health service ill-equipped in meeting their needs. Improvements, including alternative consulting approaches, are required to improve care quality and patient engagement. We examined how group-based, outpatient diabetes consultations might be delivered to support young people (16-25 years old) in socio-economically deprived, ethnically diverse settings. METHODS: This multi-method, comparative study recruited a total of 135 young people with diabetes across two implementation and two comparison sites (2017-2019). Informed by a 'researcher-in-residence' approach and complexity theory, we used a combination of methods: (a) 31 qualitative interviews with young people and staff and ethnographic observation in group and individual clinics, (b) quantitative analysis of sociodemographic, clinical, service use, and patient enablement data, and (c) micro-costing analysis. RESULTS: Implementation sites delivered 29 group consultations in total. Overall mean attendance per session was low, but a core group of young people attended repeatedly. They reported feeling better understood and supported, gaining new learning from peers and clinicians, and being better prepared to normalise diabetes self-care. Yet, there were also instances where peer comparison proved difficult to manage. Group consultations challenged deeply embedded ways of thinking about care provision and required staff to work flexibly to achieve local tailoring, sustain continuity, and safely manage complex interdependencies with other care processes. Set-up and delivery were time-consuming and required in-depth clinical and relational knowledge of patients. Facilitation by an experienced youth worker was instrumental. There was indication that economic value could derive from preventing at least one unscheduled consultation annually. CONCLUSIONS: Group consulting can provide added value when tailored to meet local needs rather than following standardised approaches. This study illustrates the importance of adaptive capability and self-organisation when integrating new models of care, with young people as active partners in shaping service provision.

Group clinics for young adults living with diabetes in an ethnically diverse, socioeconomically deprived population: mixed-methods evaluation

Background Our research was based on the expressed need to evaluate the potential for group clinics to enhance care within the NHS for people with long-term conditions. Objectives We aimed to explore the scope, feasibility, impact and potential scalability of group clinics for young adults with diabetes who have poor experiences of care and clinical outcomes. We applied a participatory approach to the entire research process, where appropriate. Setting Four NHS trusts delivering diabetes care to young adults in ethnically diverse and socioeconomically deprived communities. Participants We involved 135 young adults as participants in our research (73 at two intervention sites and 62 at two control sites). Methods A realist review synthesised existing evidence for group clinics to understand ‘what works, for whom, under what circumstances’. Using the realist review findings and a scoping exercise, we used co-design to develop a model of group clinic-based care, which we then implemented and evaluated using primarily qualitative methods, with quantitative and costs analyses to inform future evaluations. Results Young adults reported positive experiences from the group clinics. However, across the group clinics delivered, only one-third (on average) of those invited to specific clinics attended, despite substantial efforts to encourage attendance, and only 37 out of 73 (51%) participants attended any group clinics. Social learning helped the acquisition of new knowledge and normalisation of experiences. Group clinics met previously unreached emotional needs, and the relationships that formed between young adults, and between them and the staff facilitating the clinics, were key. Clinical staff delivered the clinics using a facilitatory approach, and a youth worker helped to ensure that the care model was developmentally appropriate. Existing organisational structures presented substantial challenges to the delivery of group clinics, and there was considerable hidden work required by the staff delivering them. Group clinics may augment one-to-one care but do not necessarily replace it. The average cost of each group clinic, per participant, was £127–58. Limitations Engagement in co-design and the research process and participation in the group clinics was challenging, and limited our quantitative data analysis. These limitations had implications for the fidelity of the intervention and generalisability of our findings. During the research, we established that group clinics would not replace existing care, and that further work is required to understand the theoretical base of ‘blended’ models of care, and the potential of digital offers, before a definitive evaluation (a cluster-randomised trial) can be designed. Conclusions Our findings show that young adults with diabetes, including those in deprived and ethnically diverse settings, have positive experiences of group-based care, and it may augment existing one-to-one care. However, engagement with group-based care is challenging despite the participatory design. Future work Future research is needed to develop the group clinic model prior to definitive evaluation.

Spermatogonial stem cell sensitivity to capsaicin: An in vitro study

<p>Abstract</p> <p>Background</p> <p>Conflicting reports have been published on the sensitivity of spermatogenesis to capsaicin (CAP), the pungent ingredient of hot chili peppers. Here, the effect of CAP on germ cell survival was investigated by using two testis germ cell lines as a model. As CAP is a potent agonist of the transient receptor potential vanilloid receptor 1 (TRPV1) and no information was available of its expression in germ cells, we also studied the presence of TRPV1 in the cultured cells and in germ cells in situ.</p> <p>Methods</p> <p>The rat spermatogonial stem cell lines Gc-5spg and Gc-6spg were used to study the effects of different concentrations of CAP during 24 and 48 h. The response to CAP was first monitored by phase-contrast microscopy. As germ cells appear to undergo apoptosis in the presence of CAP, the activation of caspase 3 was studied using an anti activated caspase 3 antibody or by quantifying the amount of cells with DNA fragmentation using flow cytometry. Immunolocalization was done with an anti-TRPV1 antibody either with the use of confocal microscopy to follow live cell labeling (germ cells) or on Bouin fixed paraffin embedded testicular tissues. The expression of TRPV1 by the cell lines and germ cells was confirmed by Western blots.</p> <p>Results</p> <p>Initial morphological observations indicated that CAP at concentrations ranging from 150 uM to 250 uM and after 24 and 48 h of exposure, had deleterious apoptotic-like effects on both cell lines: A large population of the CAP treated cell cultures showed signs of DNA fragmentation and caspase 3 activation. Quantification of the effect demonstrated a significant effect of CAP with doses of 150 uM in the Gc-5spg cell line and 200 uM in the Gc-6spg cell line, after 24 h of exposure. The effect was dose and time dependent in both cell lines. TRPV1, the receptor for CAP, was found to be expressed by the spermatogonial stem cells in vitro and also by premeiotic germ cells in situ.</p> <p>Conclusion</p> <p>CAP adversely affects spermatogonial survival in vitro by inducing apoptosis to those cells and TRPV-1, a CAP receptor, may be involved in this effect as this receptor is expressed by mitotic germ cells.</p

Electrochemical and thermodynamic studies to evaluate the inhibition effect of synthesized piperidine derivatives on the corrosion of mild steel in acidic medium

The inhibition ability of three newly synthesized piperidine sulphonamides toward the mild steel (MS) corrosion was investigated using mass loss and electrochemical techniques. The adsorption of all the piperidine sulphonamides on MS complies with the Langmuir isotherm model in all studied temperatures. Associated activation and adsorption thermodynamic parameters were computed and discussed. The polarization results indicated that all the studied inhibitors act as mixed type of corrosion inhibitors. The protective layer of organic compounds on MS surface was confirmed by scanning electron microscopy (SEM). The values of free energy of adsorption (Delta G (ads)) revealed that the inhibitors adsorbed on the MS surface via both chemisorption and physisorption mechanisms. The relationship between inhibition efficiency and molecular structures of inhibitors was discussed using quantum chemical parameters. The inhibition efficiencies obtained from mass loss and electrochemical measurements were in good agreement
