Wnt proteins represents highly conserved family of signalling biomolecules regulating vital developmental processes including embryo axis patterning, regeneration potential, cell fate specificity and determination in animals. Existence of Wnt protein mediated signalling in plants is still unexplored. Homologs of proteins like glycogen-synthase-kinase-3, casein-kinase-1 and Adenomatous-polyposis coli which together act as a negative regulator of metazoan Wnt signalling, have been traced in plants. Interestingly, genome-wide survey of cotton could reveal the presence of Wnt protein and its receptor, Frizzled up in Gossypium arboreum. Moreover, publicly available annotated sequence data have unravelled the existence of certain other proteins like Dishevelled homologs of betacatenin in plants. These proteins orchestrate the initiation of Wnt signalling pathway in animals. Manifestation of homologs of such Wnt signalling factors in plants, indicates a possible mimicry of similar signalling pathways. We have attempted to hypothesize a novel signalling network involving Wnt protein and other associated proteins in plants, considering animal systems as a model.Keywords

Objectives: In this paper an experimental study is carried out to reduce the exhaust gas temperature of a Spark Ignition (SI) engine by injecting water in the intake manifold. Methods/Statistical Analysis: The reduction of exhaust gas temperature decreases the NOx emissions. To achieve this, an experimental setup was fabricated to spray water using a small compressor at the intake manifold. A solenoid valve is used to regulate the water injection; the solenoid valve was in turn controlled by an electrical circuit. The temperature of exhaust gas was measured continuously using ‘J’ type thermocouple and digital temperature indicator. Findings: Injection of water just after the carburettor in the intake manifold reduced the overall temperature of the cylinder due to higher latent heat of vaporization. As the temperature inside the cylinder is reduced, harmful emissions such as NOx and CO are reduced thus bringing down the pollution to a greater extent. Applications/Improvements: In order to reduce the pollution caused due to automobile emission can be controlled by injection of water in the intake manifold.Keywords

In the absence of mandatory reporting requirements in India, few corporate bodies make environmental disclosure purely on voluntary basis in the form of sustainability reporting. Thus, the purpose of the present paper is to assess whether Bharat Heavy Electricals Limited furnishes environmental information in accordance with the Global Reporting Initiative (GRI) guidelines and also to measure the performance of the company on the basis of the selected environmental performance indicators. The data for the present study has been collected from the Sustainability Report of the company and covers a time span of five years starting from 2012-13. The key findings of the study indicate that the company provides adequate information on selected environmental performance indicators in accordance to the GRI guidelines and also reported that the company has been able to reduce the consumption of resources like coal and diesel on year-to-year basis. It is recommended that the company should make disclosure on materials and natural resources used by manufacturing units in terms of volume and weight.Keywords

Introduction: Alopecia Areata (AA) is one of the most common form of hair loss seen in dermatology. Treatment failures can occur with almost every conventional therapy, either singly or in combination. Aims and Objectives: To study the clinical profiles and management outcome of Liquid Nitrogen Cryotherapy (LNC) for the treatment of unresponsive cases of AA. Materials and Methods: A prospective study was conducted on five patients who showed no response to conventional topical treatment for six months. The subjects were enrolled in the study after written consent. Clinical photographs were recorded at each visit. Patients were given 3-5 sittings of LNC at 2 week intervals. Each session consisted of dual freeze thaw cycles of 15 seconds each, with a cryospray technique following application of topical anaesthetic cream. Suitable antibiotics and anti-inflammatory agents were prescribed post-operatively for five days. The clinical response was evaluated by using regrowth scale at 4th week and 8th week. Final end point evaluation of patient post 3 months after the last treatment session was done to observe sustained regrowth of hair. Results: Five patients were recruited, out of which three patients showed an excellent response, 1 each had a satisfactory response and a fair response respectively. Commonly seen adverse effects were slight pain, erythema, edema, erosion, crusting, dyspigmentation/hypopigmentation, which were transient and did not require withdrawal of treatment. Conclusion: Liquid Nitrogen Cryotherapy is a cheaper, easily available with transient adverse effects and can be worth trying in unresponsive Alopecia Areata.Keywords

The present study documented the behaviour of stock of the Indian banking sector around the announcements of dividends before and during the global health crisis of 2019. The study considered all the banks in the Indian banking sector that have announced the dividend from January 2015 to December 2021 and conducted the analysis using event study methodology with Multi-Index Model (MIM). The study found that during the pre-crisis period, the stock of the PSU banks were more sensitive towards the announcements when dividends were decreased compared to the announcements when it was increased. While, stock of private banks was significantly impacted by both positive and negative dividend announcements, however, the impact of negative dividend announcements was severe and more prolonged than that of positive dividend announcements. Further, during the COVID 19 Pandemic, it is witnessed that information relating to dividend announcement has positively affected the behaviour of the banking sector stock.Keywords
