C CSA Tensors and Orientational Order of Model and Dimer Mesogens Comprising of Phenyl Benzoate.

A Model mesogen and its symmetrical Dimer made up of phenyl benzoate core unit are investigated by C NMR spectroscopy. The existence of layer order in smectic A and smectic C phases of Dimer mesogen is established by powder X-ray diffraction. The chemical shift anisotropy (CSA) tensors of Model mesogen are determined by 2D separation of undistorted powder patterns by effortless recoupling (SUPER) experiment and are utilized for calculating the order parameters employing the alignment-induced chemical shifts (AIS).

Glassy relaxation in a de Vries smectic liquid crystal consisting of bent-core molecules.

We report experimental investigations of a liquid crystal comprising thiophene-based achiral bent-core banana shaped molecules. The compound exhibits the following phase sequence on cooling: Isotropic (517.4 K), N (514.

Exploration of bioactive compounds from in Western Ghats of Karnataka using GC-MS.

Bioactive compounds in plants are essential for the formation of novel chemotherapeutic drugs, which have been used in Ayurveda to treat a variety of illnesses. Indian medicinal herbs have been used for thousands of years to treat a variety of illnesses, such as fever, cancer, snake bites, rheumatism, skin problems, and neurodegenerative diseases. GC-MS was used to locate and categorize bioactive components in leaves.

Influence of the Thiophene Ring on the Molecular Order of Structurally Simple π-Conjugated Smectogens: C NMR Study.

Structurally simple rod-like π-conjugated mesogens with thiophene directly connected to phenyl, biphenyl, and fluorenone rings with terminal chains are synthesized respectively. The occurrence of smectic A/smectic C phases is concurred by a hot-stage optical polarising microscope (HOPM), differential scanning calorimetry (DSC), and X-ray diffraction (XRD). The static 1D and 2D C nuclear magnetic resonance (NMR) studies in the liquid crystalline phase are carried out to find the alignment-induced chemical shifts (AIS) and C- H dipolar couplings.

Applicability of Two Universally Accepted Mixed Dentition Analysis on a Sample from Southeastern Region of Andhra Pradesh, India.

Background: Most of the universally accepted mixed dentition analyses are based on the data derived from northwestern European descent. However, the accuracy of these methods when applied to different ethnic population is questionable.

Aim: The present study is aimed to evaluate the applicability of Tanaka and Johnston (TJ) and Moyers (50(th) and 75(th) percentile) mixed dentition analysis in a sample from south-eastern region of Andhra Pradesh, India.

Evaluation of three medicinal plants for anti-microbial activity.

Herbal remedies have a long history of use for gum and tooth problems such as dental caries. The present microbiological study was carried out to evaluate the antimicrobial efficacy of three medicinal plants (Terminalia chebula Retz., Clitoria ternatea Linn.

Ethno medical studies in kailasagirikona forest range of chittoor district, andhra pradesh.

The present study reveals the Ethno Botanical studies on uses of medicinal plants in Kailasagiri forest range of Chittoor district, Andhra Pradesh. Role of these studies in rural and forest economies is immense. Tribal people of this area have authentic information on medicinal values of different plant parts like leaves, fruits, flowers, seeds, stem bark, tubers and roots.

Ethno Medical Studies In Talakona Forest Range of Chittor District, Andhra pradesh.

The flora of Talakona forest division has been studied for its ethnomedicinal wealth (Hemadri et al, Madhava Chetty et al). These studies have contributed immensely to the rural and forest economy. The present study revealed the medicinal use of 66 species of plants distributedin 40families.

Historical perspective on the usage of perfumes and scented Articles in ancient Indian literatures.

In India perfumes and scented articles were in use from pre Vedic and Vedic periods for religious practices, social customs, and domestic rituals and later gradually became part and parcel of human life. Perfumes were also used in cosmetics and beauty aids. Medicinal values of many perfumes were well known to ancient Indians and were used in both rituals and to treat diseases.

Nutritional status in renal transplant recipients.

We performed this study to observe the nutritional status in our renal transplant recipients using serum parameters, body mass index (BMI), and dual energy x-ray absorptiometry (DEXA) that measured the fat distribution. We studied 109 patients who had chronic kidney disease due to different etiologies, and received mean hemodialysis before they underwent successful renal transplantation. The body mass index and the prevalence of type 2 diabetes mellitus revealed a significantly positive correlation with older age (p< 0.
