Spontaneous intracranial hypotension and single entry multi-site epidural blood patch.

Asian journal of neurosurgery

Murphy D, Chandna A, Laing A, MacFarlane M.
PMID: 26396625
Asian J Neurosurg. 2015 Jul-Sep;10(3):262-4. doi: 10.4103/1793-5482.161168.

The syndrome of spontaneous intracranial hypotension is often difficult to treat. Unfortunately, cerebrospinal fluid leaks are often numerous and difficult to detect radiologically. Multiple entries to the spinal epidural space, in an effort to alleviate symptoms, are therefore sometimes...

Immature Gastric Teratoma in a Newborn: A Case Report.

Journal of neonatal surgery

Kumar S, Yadav H, Rattan KN, Srivastava D, Chandana A, Prakash S.
PMID: 27123405
J Neonatal Surg. 2016 Apr 10;5(2):21. eCollection 2016.

A case of immature gastric teratoma in a neonate is being reported here. The neonate was presented with abdominal mass and distension and managed with excision of mass; the patient is doing fine postoperatively.

Frontal bone metastasis from an occult follicular thyroid carcinoma: Diagnosed by FNAC.

Journal of cytology

Kalra R, Pawar R, Hasija S, Chandna A, Sankla M, Malhotra C.
PMID: 28182063
J Cytol. 2017 Jan-Mar;34(1):59-61. doi: 10.4103/0970-9371.197623.

Metastatic deposits in skull bones from follicular thyroid carcinoma is rare, and metastatic disease in skull being the presenting symptom without obvious thyroid lesion (occult primary) is even rarer. A 60-year-old female patient presented with a mass in the...

The use of the fluorescein disappearance test in the management of childhood epiphora.

Orbit (Amsterdam, Netherlands)

Bowyer JD, Holroyd C, Chandna A.
PMID: 12045910
Orbit. 2001 Sep;20(3):181-187. doi: 10.1076/orbi.20.3.181.2620.

PURPOSE. The fluorescein disappearance test (FDT) is reported to be an objective measure of lacrimal outflow in congenital non-canalisation of the nasolacrimal system. We introduced FDT into our evaluation of children with epiphora to investigate its sensitivity/specificity with regard...

Two kinds of smectic-C(alpha)* subphases in a liquid crystal and their relative stability dependent on the enantiomeric excess as elucidated by electric-field-induced birefringence experiment.

Physical review. E, Statistical, nonlinear, and soft matter physics

Shtykov NM, Chandani AD, Emelyanenko AV, Fukuda A, Vij JK.
PMID: 15783344
Phys Rev E Stat Nonlin Soft Matter Phys. 2005 Feb;71(2):021711. doi: 10.1103/PhysRevE.71.021711. Epub 2005 Feb 28.

The electric-field-induced birefringence has been investigated by using a photoelastic modulator, with a view to obtaining a molecular model for the subphases produced by the frustration between ferroelectricity and antiferroelectricity in the chiral smectic liquid crystals. It has been...

Anion and cation binding by a pendant arm cyclam and its macrobicyclic derivatives.

Dalton transactions (Cambridge, England : 2003)

Channa A, Steed JW.
PMID: 15995757
Dalton Trans. 2005 Jul 21;(14):2455-61. doi: 10.1039/b504561d. Epub 2005 Jun 10.

A series of transition-metal complexes of N,N',N'',N'''-tetra(3-hydroxypropyl)cyclam (L1) are reported. The X-ray structures of the compounds reveal pendant arm coordination of one of the alcohol groups to give square-pyramidal metal centres with simultaneous hydrogen bonding to the counter anions....

Stimulus-responsive Au@(MeO2MAx-co-OEGMAy) nanoparticles stabilized by non-DLVO interactions: implications of ionic strength and copolymer (x:y) fraction on aggregation kinetics.

Langmuir : the ACS journal of surfaces and colloids

Gambinossi F, Chanana M, Mylon SE, Ferri JK.
PMID: 24517439
Langmuir. 2014 Feb 25;30(7):1748-57. doi: 10.1021/la403963c. Epub 2014 Feb 11.

Functionalized nanoparticles can assist in stabilizing fluid-fluid interfaces; however, developing and applying the appropriate surface modification presents a challenge because successful application of these nanomaterials for biotechnological, food processing, and environmental applications requires their long-term stability in elevated ionic...

Magneto-Electroluminescence Study of Fringe Field in "Magnetic" Organic Light-Emitting Diodes.

ACS applied materials & interfaces

Liu X, Chanana A, Liu H, Wang J, Kwon O, Choi B, Kim S, Vardeny ZV.
PMID: 31339685
ACS Appl Mater Interfaces. 2019 Aug 21;11(33):30072-30078. doi: 10.1021/acsami.9b07512. Epub 2019 Aug 06.

Magneto-electroluminescence (MEL) represents the electroluminescence intensity change upon application of an external magnetic field. We show that the MEL field response in "magnetic" organic light-emitting diodes, where one electrode is ferromagnetic (FM), is a powerful technique for measuring the...

Reliability of cone beam computed tomography as a biopsy-independent tool in differential diagnosis of periapical cysts and granulomas: An .

Journal of conservative dentistry : JCD

Chanani A, Adhikari HD.
PMID: 29386780
J Conserv Dent. 2017 Sep-Oct;20(5):326-331. doi: 10.4103/JCD.JCD_124_17.

BACKGROUND: Differential diagnosis of periapical cysts and granulomas is required as their treatment modalities are different.AIM: The aim of this study was to evaluate the efficacy of cone beam computed tomography (CBCT) in the differential diagnosis of periapical cysts...

Ultrafast frequency-agile terahertz devices using methylammonium lead halide perovskites.

Science advances

The ability to control the response of metamaterial structures can facilitate the development of new terahertz devices, with applications in spectroscopy and communications. We demonstrate ultrafast frequency-agile terahertz metamaterial devices that enable such a capability, in which multiple perovskites...

Fighting the Cause of Alzheimer's and GNE Myopathy.
