Employability assessment of computerized fatigue avoidance tool used with and without actigraphy among naval aircrew.

Background: Fatigue Avoidance Scheduling Tool (FAST) is a computerized fatigue prevention tool, which was developed based on a Bio-mathematical model called SAPTE (Sleep, Activity, Performance and Task Effectiveness). Similarly, actigraphy technology is used as a tool for sleep evaluation. This study was an attempt to assess the employability of FAST (both independently and integrated with actigraphy) for detecting operational fatigue by determining the 'Measures for diagnostic accuracy'.

Cost-effective and power-efficient portable turbine-based emergency ventilator.

Ventilators have always been common in medical scenarios but are very expensive to procure or develop. One of the main reasons for these is the components that are being used are expensive and require precise instrumentation, research, and development. This paper attempts to mitigate that problem by proposing a novel way to rapidly develop a portable ventilator that uses common 3D printing technology and off-the-shelf components.

An assessment of perceived social support among naval personnel.

Background: Studies from the Indian Navy have found junior sailors to have higher occupational stress than senior sailors. Positive social support can provide protection against detrimental effects of stress and facilitate in development of individual resilience. Therefore, the present study was conducted to explore the level of perceived social support among naval personnel.

Fine needle aspiration cytology of epididymal nodules and its corroboration with ultrasonographic-histological findings.

Background: Fine needle aspiration cytology (FNAC) assisted with scrotal ultrasonography is the best preoperative diagnostic modality for palpable epididymal nodules. It also aids in their successive remedial approach as well as serves semi-therapeutically in cystic lesions. The objectives of this study are to recognize the spectrum of pathological conditions giving rise to epididymal nodules, then to compare them with corresponding ultrasound images, and to evaluate the histological features wherever practicable.

Prosthetic grafts for haemodialysis access: 10 years experience.

Implantation of prosthetic vascular grafts is sometimes necessary to create vascular access as AV conduits for maintenance haemodialysis. Though more common in the western world, it is now also becoming an important option in our country. Here we summarise our experience with the procedure from 2001 to 2011.

Preparation and evaluation of 99mTc-cefuroxime, a potential infection specific imaging agent: a reliable thin layer chromatographic system to delineate impurities from the 99mTc-antibiotic.

Technetium-99m labelled cefuroxime, a second-generation cephalosporin antibiotic and potential bacteria specific infection imaging agent was evaluated. A good radiochemical purity (95%) of the labelled product was obtained after filtering the reaction mixture through a 0.22 μm filter.

Pyridinium-based symmetrical diamides as chemosensors in visual sensing of citrate through indicator displacement assay (IDA) and gel formation.

The design and synthesis of pyridinium-based symmetrical diamides 1 and 2 along with their anion binding studies through 'indicator-diplacement assay' are reported. Both the chemosensors effectively respond in in CH(3)CN-H(2)O (4 : 1 v/v) at pH = 6.3 for the selective naked-eye detection of citrate.

Synthesis and evaluation of (99m)Tc-moxifloxacin, a potential infection specific imaging agent.

To synthesize and evaluate a (99m)Tc labeled fluroquinolone, moxifloxacin as a potential bacteria specific infection imaging agent. A radiolabeling formulation including moxifloxacin, [Moxicip(TM) injection, Cipla] (4mg), sodium pertechnetate and stannous chloride (5microg) gave the best radiolabeling efficiency and moderately stable labeled (99m)Tc moxifloxacin. Quality control analysis was performed by ITLC.
