Hair Loss in Children: A Clinicoetiological Study from South India.

Background: Scalp hair loss in children is one of the common complaints encountered in dermatological practice. Accurate diagnosis of hair loss in children is of major significance as it can have severe psychological implications given the cosmetic importance of hair.

Aims: This study aims to study the different causes and clinical presentations of scalp hair loss in children.

Follicular Unit Grafting in Chronic Nonhealing Leg Ulcers: A Clinical Study.

Introduction And Objectives: The restoration of the epithelium after injury takes place by migration of epithelial cells adjoining a wound or by centrifugal migration from hair follicles. To evaluate the feasibility and potential healing capacity of scalp follicular unit grafts transplanted into the wound bed of chronic leg ulcers.

Materials And Methods: Patients with chronic nonhealing ulcers of more than 6 weeks duration were selected for the study.

Laser frequency locking with 46 GHz offset using an electro-optic modulator for magneto-optical trapping of francium atoms.

We demonstrate frequency offset locking between two laser sources using a waveguide-type electro-optic modulator (EOM) with 10th-order sidebands for magneto-optical trapping of Fr atoms. The frequency locking error signal was successfully obtained by performing delayed self-homodyne detection of the beat signal between the repumping frequency and the 10th-order sideband component of the trapping light. Sweeping the trapping-light and repumping-light frequencies with keeping its frequency difference of 46 GHz was confirmed over 1 GHz by monitoring the Doppler absorption profile of I₂.

A Study of Hair Follicular Transplantation as a Treatment Option for Vitiligo.

Background: Repigmentation of vitiligo is closely related to hair follicles. Hence, replenishing melanocytes in vitiliginous patches utilizing undifferentiated stem cells of the hair follicles using follicular unit transplantation (FUT) is a possible treatment option.

Objectives Of The Study: To study the efficacy of FUT in cases of segmental/stabilized vitiligo as a treatment option for leukotrichia.

Radioactive ion beam transportation for the fundamental symmetry study with laser-trapped atoms.

The search for the violation of the fundamental symmetry in a radioactive atom is the promising candidate for precision tests of the standard model and its possible extensions. The subtle signal arising from the symmetry violation is enhanced in heavy atoms, such as a francium (Fr). To realize high precision measurements, a large amount of radioactive isotopes is required.

Disseminated cutaneous cysticercosis and neurocysticercosis: A rare occurrence.

Disseminated cysticercosis is a parasitic infestation of pork tapeworm, Taenia solium. A 19-year-old female presented with multiple nodules all over her body since 12 months. Histopathology showed features suggestive of parasitic granuloma with multinucleated giant cells and plenty of eosinophils admixed with necrosis.

Reappraisal of the electric dipole moment enhancement factor for thallium.

The electric dipole moment (EDM) enhancement factor of atomic Tl is of considerable interest as it has been used in determining the most accurate limit on the electron EDM to date. However, its value varies from -179 to -1041 in different approximations. In view of the large uncertainties associated with many of these calculations, we perform an accurate calculation employing the relativistic coupled-cluster theory and obtain -466, which in combination with the most accurate measurement of Tl EDM [Phys.

General implementation of the relativistic coupled-cluster method.

We report the development of a general order relativistic coupled-cluster (CC) code. Our implementation is based on Kramers-paired molecular spinors, utilizes double group symmetry, and is applicable with the full Dirac-Coulomb and several approximate relativistic Hamiltonians. The available methods include iterative and perturbative single-reference CC approaches with arbitrary excitations as well as a state-selective multi-reference CC ansatz.

Relativistic coupled cluster (RCC) computation of the electric dipole moment enhancement factor of francium due to the violation of time reversal symmetry.

A relativistic many-body theory for the electric dipole moment (EDM) of paramagnetic atoms arising from the electric dipole moment of the electron is presented and implemented. The relativistic coupled-cluster method with single and double excitations (RCCSD) using the Dirac-Coulomb Hamiltonian and a weak parity and time reversal violating interaction to the first-order of perturbation has been employed to obtain the EDM enhancement factor for the ground state of the Fr atom due to the intrinsic EDM of the electron. The trends of different correlation effects and the leading contributions from different physical states are discussed.

Pharmacognostic and Phytochemical analysis of different market samples of Ashoka (Saraca indica Linn).

Different market samples of Ashoka (Saraca indica Linn) were analyzed to screen the genuinity of the samples available in the market in the name of Ashoka. All the samples were subjected for Pharmacognostic and Phytochemical analysis and found that all the samples were derived from the different botanical sources.

Intrinsic electric dipole moments of paramagnetic atoms: rubidium and cesium.

The electric dipole moment (EDM) of paramagnetic atoms is sensitive to the intrinsic EDM contribution from that of its constituent electrons and a scalar-pseudoscalar (S-PS) electron-nucleus interaction. The electron EDM and the S-PS contributions to the EDMs of these atoms scale as approximately Z;{3}. Thus, the heavy paramagnetic atoms will exhibit large EDM enhancement factors.
