Profitability Of Price, Earnings And Revenue Momentum Strategies: The Indian Evidence

Momentum has remained an unsettled anomaly in finance. In this paper, we examine the profitability of univariate and multivariate sorted momentum strategies based on prior returns, earnings surprises and revenue surprises using the data for 493 companies that form part of Bombay Stock Exchange (BSE) 500 index in India from January 2002 to June 2010. Momentum profits are found to be persistent in the intermediate horizon (up to six months). Price momentum winners provide higher returns vis-à-vis earnings and revenue momentum winners. On long-short basis, earnings momentum strategy is most profitable. Earnings momentum is able to subsume price and revenue momentum. Further, the informational content of revenue surprises is incrementally very small. Triple sorted momentum portfolio using all the three criteria provides the highest return of 2.28% per month. The Capital Asset Pricing Model (CAPM) and the Fama-French model fail to explain these returns. The post-holding analysis reveals strong overreaction patterns for both winners as well as losers, thus, supporting the behavioural explanation. Momentum winners and losers perform better during market upturns. This study contributes to the asset pricing and behavioral finance literature especially for emerging markets such as India

Amnion and Chorion Membranes: Potential Stem Cell Reservoir with Wide Applications in Periodontics

The periodontal therapy usually aims at elimination of disease causing bacteria and resolution of inflammation. It involves either resective or regenerative surgery to resolve the inflammation associated defects. Over the years, several methods have been used for achievement of periodontal regeneration. One of the oldest biomaterials used for scaffolds is the fetal membrane. The amniotic membranes of developing embryo, that is, amnion (innermost lining) and chorion (a layer next to it), have the properties with significant potential uses in dentistry. This paper reviews the properties, mechanism of action, and various applications of these placental membranes in general and specifically in Periodontics

An unusual case report of basal cell adenoma: a diagnostic enchanter

Oral lesions show a wide range of biologic behaviours. There are various lesions which may mimic others and present in such an unusual manner thus making them very difficult to diagnose clinico-pathologically. An accurate diagnosis is not only important for correct treatment planning but also for determination of prognosis. Thus, it is very important for a surgical pathologist to be aware of the various atypical presentations of the lesions. The present unusual case report of basal cell adenoma occurring on upper lip with frank areas of calcifications and abundant inspissated mucoid secretions is an example of one such case. BCA is an uncommon benign epithelial salivary gland neoplasm. It is one of the nine subcategories of salivary gland epithelial tumours according to WHO 2005 classification of salivary gland tumors. It is composed of basaloid cells organized with a prominent basal cell layer and distinct basement membrane-like structure and no myxochondroid stromal component as seen in pleomorphic adenomas. To our best knowledge, no case in English literature has been reported BCA with exuberant inspissated mucoid secretions and frank areas of calcifications to such a large extent and this is the first case to report the same

Semiconducting Metal Oxide Based Sensors for Selective Gas Pollutant Detection

A review of some papers published in the last fifty years that focus on the semiconducting metal oxide (SMO) based sensors for the selective and sensitive detection of various environmental pollutants is presented

A rare presentation of lipoma on mandibular mucogingival junction

Lipoma is the most common tumor of mesenchymal tissues of body, but its occurrence in oral cavity is infrequent. Buccal mucosa is the most common intraoral site of lipoma followed by tongue, floor of the mouth, and buccal vestibule. The involvement of mucogingival junction is rare. We present a unique case report of oral lipoma occurring on mandibular mucogingival junction with review of literature which has emphasis on differential diagnosis

Kaleidoscope of oral artifacts: A vivid picture through light and polarizing microscope

Background: This study is based on finding of an inexplicable artifact that was seen in the tissue received as periapical granuloma. Aim: To observe the histological appearance of different commonly implanted food particles and easily incorporated substances from a laboratory in the oral biopsy tissues. Materials and Methods: Various food particles such as wheat chapatti, beans, peas, pulses, and coriander leaves and substances such as a suture, cotton, and paper that can easily gain entry during biopsy and histotechnical procedures were intentionally introduced in the tissue specimens of a uterus from outside. Both light and polarizing microscopes were utilized to view them. Results: Different food particles and substances gave different appearances that could lead to misdiagnosis. Some of these also exhibited positive birefringence under the polarizing microscope. Conclusion: Knowledge and familiarity with probable foreign substances which can appear in tissues may help prevent misdiagnosis or erroneous diagnosis of biopsy specimens

An Observation Study to Evaluate the Drug Utilization Pattern for Oral Cancer Patients Receiving Chemotherapy Treatment at a Private and Government Tertiary Care Hospital in Jaipur City

Background: As oral cavity and oropharynx cancers are the second most common type of tobacco-related cancer reported in Jaipur city so it is imperative to study the drug utilization pattern in these cancers. Objectives: The objective of this study was to evaluate the trends in drug usage patterns for oral cancer patients in Jaipur city. Methods: The prescriptions of oral cancer patients attending the outpatient department of SMS Medical College and Bhagwan Mahaveer Cancer and Research Centre from May 2017 to August 2017 were studied. They were studied for WHO Prescribing indicators for good prescribing practice. Results: A total of 188 prescriptions were studied. Average number of drugs per prescription was 7.4±1.8. The combination of paclitaxel and carboplatin was the most frequently prescribed antineoplastic drug, prescribed to 29.8% of patients. The drafting of the prescriptions was of average quality. In 5% of the prescriptions, a diagnosis was omitted, and in 48% of the prescriptions, the patient’s weight and/or body surface area (BSA) were omitted. Only 52% of the prescriptions contained the medications’ generic names. Conclusion: The quality of prescribing was fair and moderately acceptable. To ensure rational prescribing and safe and successful treatment of cancer patients, interventions such as new policy formulation and educational measures should be developed
