Scientific reports

Arora A, Cameotra SS, Kumar R, Balomajumder C, Singh AK, Santhakumari B, Kumar P, Laik S.
PMID: 26869357
Sci Rep. 2016 Feb 12;6:20893. doi: 10.1038/srep20893.

Natural gas hydrates (NGHs) are solid non-stoichiometric compounds often regarded as a next generation energy source. Successful commercialization of NGH is curtailed by lack of efficient and safe technology for generation, dissociation, storage and transportation. The present work studied...

Tuning the Magnetic Properties of Iron Oxide Nanoparticles by a Room-Temperature Air-Atmosphere (RTAA) Co-Precipitation Method.

Journal of nanoscience and nanotechnology

Vikram S, Dhakshnamoorthy M, Vasanthakumari R, Rajamani AR, Rangarajan M, Tsuzuki T.
PMID: 26505017
J Nanosci Nanotechnol. 2015 May;15(5):3870-8. doi: 10.1166/jnn.2015.9544.

The ability of a room-temperature air-atmosphere (RTAA) co-precipitation method to tune the magnetic properties of iron oxide nanoparticles was investigated. It was demonstrated that superparamagnetic nanoparticles with different particle sizes ranging from 7 to 25 nm and magnetic properties...

Determination of oxidative stress related toxicity on repeated dermal exposure of hydroxyapatite nanoparticles in rats.

International journal of biomaterials

Parayanthala Valappil M, Santhakumar S, Arumugam S.
PMID: 25587279
Int J Biomater. 2014;2014:476942. doi: 10.1155/2014/476942. Epub 2014 Dec 21.

Hydroxyapatite nanoparticles (HANPs) have numerous applications, such as substitute for bone grafting, bone fillers, bioceramic coating, and dental fillings. The toxicity of these nanomaterials is of growing concern despite their significant scientific interest and promising potential in many applications....

PMID: 27012441
ISA Trans. 2016 Jul;63:218-232. doi: 10.1016/j.isatra.2016.02.016. Epub 2016 Mar 21.

In this paper, a robust nonlinear proportional-integral-derivative (PID)-like fuzzy control scheme is presented and applied to complex trajectory tracking control of a 2PRP-PPR (P-prismatic, R-revolute) planar parallel manipulator (motion platform) with three degrees-of-freedom (DOF) in the presence of parameter...

ROLE OF YOGA IN ALIENATING THE MEMORY DECLINE AND FRONTAL LOBE METABOLITE CHANGES IN TYPE 2 DIABETES.

International journal of research in ayurveda and pharmacy

Santhakumari R, Reddy IY, Archana R, Rajesh P.
PMID: 27390721
Int J Res Ayurveda Pharm. 2016 Jan-Feb;7(1):78-81. doi: 10.7897/2277-4343.07116.

Recent research studies have established the fact, that glycosylation is causing the memory decline and this is further supported by the alteration of brain metabolite concentrations in diabetes. The present study is hypothesized that yoga is having alienating ability...

Protoplast volume:water potential relationship and bound water fraction in spinach leaves.

Plant physiology

Santakumari M, Berkowitz GA.
PMID: 16666983
Plant Physiol. 1989 Sep;91(1):13-8. doi: 10.1104/pp.91.1.13.

Methods used to estimate the (nonosmotic) bound water fraction (BWF) (i.e. apoplast water) of spinach (Spinacia oleracea L.) leaves were evaluated. Studies using three different methods of pressure/volume (P/V) curve construction all resulted in a similar calculation of BWF;...

Congenital pouch colon: Increasing association with low anorectal anomalies.

Journal of Indian Association of Pediatric Surgeons

Pavai A, Pillai SD, Shanthakumari S, Sam CJ, Shylaja M, Sabarivinoth R.
PMID: 20419025
J Indian Assoc Pediatr Surg. 2009 Oct;14(4):218-20. doi: 10.4103/0971-9261.59606.

Three cases of type IV congenital pouch colon associated with low anorectal anomaly are reported here. Pouch colon may be a cause of intractable constipation in children operated for low anorectal anomaly. Excellent results can be obtained by exicision...
