Low-temperature broken-symmetry phases of spiral antiferromagnets.

Physical review letters

Capriotti L, Sachdev S.
PMID: 15697936
Phys Rev Lett. 2004 Dec 17;93(25):257206. doi: 10.1103/PhysRevLett.93.257206. Epub 2004 Dec 14.

We study Heisenberg antiferromagnets with nearest- (J1) and third- (J3) neighbor exchange on the square lattice. In the limit of spin S-->infinity, there is a zero temperature (T) Lifshitz point at J(3)=1/4J(1), with long-range spiral spin order at T=0...

Diabetes and the elderly brain: sweet memories?.

Therapeutic advances in endocrinology and metabolism

Samaras K, Sachdev PS.
PMID: 23323191
Ther Adv Endocrinol Metab. 2012 Dec;3(6):189-96. doi: 10.1177/2042018812469645.

Type 2 diabetes is common in older people and is associated with higher risk of both vascular dementia and Alzheimer's disease. This review examines the evidence for increased risk of dementia and mild cognitive impairment in patients with diabetes...

Evaluation of antidiabetic, antioxidant effect and safety profile of gomutra ark in Wistar albino rats.

Ancient science of life

Sachdev DO, Gosavi DD, Salwe KJ.
PMID: 23284212
Anc Sci Life. 2012 Jan;31(3):84-9. doi: 10.4103/0257-7941.103180.

The effect of Gomutra ark (GoA) on experimental alloxan-induced diabetes in rats was studied. For this purpose, Wistar albino rats of either sex weighing 200-250 g were used. The biochemical parameters like blood sugar, vitamin C, and malondialdehyde release...

Urgent need to orient public health response to rapid nutrition transition.

Indian journal of community medicine : official publication of Indian Association of Preventive & Social Medicine

Kapil U, Sachdev HP.
PMID: 23293431
Indian J Community Med. 2012 Oct;37(4):207-10. doi: 10.4103/0970-0218.103465.

India is currently undergoing a rapid transition on economic, demographic, epidemiologic, nutrition, and sociological fronts. There is evidence of a decline in undernutrition with a simultaneous escalation in overnutrition and associated non-communicable diseases (NCDs). However, the current concern and...

A clinical and follow up study of atypical psychoses.

Indian journal of psychiatry

Singh G, Sachdev JS.
PMID: 22065727
Indian J Psychiatry. 1980 Apr;22(2):167-72.

Twenty-two cases who fulfilled the criteria of having atypical manifestation at any stage of illness and had minimum follow up of three years were studied in detail. Their family history and follow up was analysed. The findings of the...

Conjoined twins.

Journal of obstetrics and gynaecology of India

Kapoor M, Sachdev N, Agrawal M.
PMID: 24431606
J Obstet Gynaecol India. 2013 Mar;63(1):70-1. doi: 10.1007/s13224-012-0138-8. Epub 2012 May 02.

Surround suppression and sparse coding in visual and barrel cortices.

Frontiers in neural circuits

Sachdev RN, Krause MR, Mazer JA.
PMID: 22783169
Front Neural Circuits. 2012 Jul 05;6:43. doi: 10.3389/fncir.2012.00043. eCollection 2012.

During natural vision the entire retina is stimulated. Likewise, during natural tactile behaviors, spatially extensive regions of the somatosensory surface are co-activated. The large spatial extent of naturalistic stimulation means that surround suppression, a phenomenon whose neural mechanisms remain...

Measurement of adult antimicrobial drug use in tertiary care hospital using defined daily dose and days of therapy.

Indian journal of pharmaceutical sciences

Bansal D, Mangla S, Undela K, Gudala K, D'Cruz S, Sachdev A, Tiwari P.
PMID: 25035532
Indian J Pharm Sci. 2014 May;76(3):211-7.

Widespread overuse and inappropriate use of antimicrobial drugs continues to fuel an increase in antimicrobial resistance and leads to consequent treatment complications and increased healthcare costs. In the present study we aimed to describe antimicrobial drug consumption and predictors...

Dietary Mineral Intake and Risk of Mild Cognitive Impairment: The PATH through Life Project.

Frontiers in aging neuroscience

Cherbuin N, Kumar R, Sachdev PS, Anstey KJ.
PMID: 24550825
Front Aging Neurosci. 2014 Feb 04;6:4. doi: 10.3389/fnagi.2014.00004. eCollection 2014.

BACKGROUND: Higher dietary intake of potassium, calcium, and magnesium is protective against ischemic strokes while also being associated with a decreased risk of all-cause dementia. The effect of dietary iron intake on cerebral function is less clear but iron...

Diastolic dysfunction in sickle cell.

Blood

Kato GJ, Sachdev V.
PMID: 20616222
Blood. 2010 Jul 08;116(1):1-2. doi: 10.1182/blood-2010-04-279919.

In adults with sickle cell disease (SCD), echocardiographic evidence of diastolic dysfunction is an independent risk factor for death that is additive to pulmonary hypertension. In this issue of Blood, Johnson and colleagues describe echocardiography and polysomnography results from...

Vector boson excitations near deconfined quantum critical points.

Physical review letters

Huh Y, Strack P, Sachdev S.
PMID: 24182284
Phys Rev Lett. 2013 Oct 18;111(16):166401. doi: 10.1103/PhysRevLett.111.166401. Epub 2013 Oct 14.

We show that the NĂ©el states of two-dimensional antiferromagnets have low energy vector boson excitations in the vicinity of deconfined quantum critical points. We compute the universal damping of these excitations arising from spin-wave emission. Detection of such a...
