The kinetic data were collected under the following conditions: 200 mg of catalyst, 2.5 % of propane in air, total flow rate of 60 mL/min, and temperature ranges of 130-170 oC. The data were fitted to the power law rate equation. The activation    energy and frequency factor were found to be 59.3 kJ/g mol and 2.9×108 (mol)0.47.L0.53/g cat.h, respectively.

Sialadenoma Papilliferum: Clinical Misdiagnosis with a Histological Decree

Sialadenoma papilliferum is a rare salivary gland tumor clinically resembling papilloma originating probably from the excretory duct. It is characterized by a biphasic growth pattern of exophytic squamous component and endophytic glandular component. We report a rare case of sialadenoma papilliferum in the floor of the mouth with epithelial dysplasia with pertinent review of literature. The present case highlights the importance of keeping sialadenoma papilliferum as a differential diagnosis of exophytic papilliferous oral lesions and the need to explore the etiology and malignant potential of the tumor

A Comparative Study on Shape Reorganization

This paper proposes a new mechanism for identifying two-dimensional shapes called the SKS algorithm and compares it with three other state-of-art methods in detail. These include the Hu Moments, CSS matching and Shape context. The algorithm uses the philosophy of evidence accumulation equal to generalized Hough transform and is highly parallel in nature. The performance of each algorithm is evaluated under affine transforms - translation, rotation in the plane, scale (zoom) and also under partial occlusion

Is Dental Treatment Safe in Pregnancy? A Dentist’s Opinion Survey in South India

Background: Oral health of pregnant patients is considered as an essential component of the overall health of the mother and the developing fetus. The aim of this study was to know dentist perspective regarding treatment options in pregnant patients. Materials and methods: A cross-sectional survey was conducted among dentists of south India by mailing a selfadministered questionnaire to collect data on management choices of the pregnant dental patient related to treatment practices and therapeutic choices of dentists and also theirsociodemographic and practice characteristics. Results: A total of 726 questionnaires was collected. Around 28.5% of the participants took radiographs for pregnant patients. Mostly, all the surveyed dentists would extract a non-restorable painful tooth during pregnancy. Around 89.3% prescribe a mouthwash and 37% would perform root planning and periodontal surgery for gingival bleeding and calculus deposits. Majority of the dentists (92.9%) prescribe amoxicillin. By far paracetamol was the most popular analgesic agent (91%).The majority of the dentists (62.3%) would use plain xylocaine Conclusion: There is a clear lack of knowledge about the appropriate management of the pregnant dental patient amongthe surveyed dentists regardless of their sociodemographic and practice characteristics necessitating continuous education on the dental management of pregnant dental patient

Increasing and sustaining diabetic retinopathy screening in Fiji by leveraging community health workers (CHWs) services: A qualitative study.

YesInequities in access to diabetic retinopathy (DR) services particularly in rural and remote Fiji is concerning. This is because DR when left undiagnosed and untreated for long, can lead to vision loss and permanent blindness. Appropriate channels must be explored to strengthen services and ensure equitable access to healthcare for everyone. This study describes the development and implementation of DR awareness training for community health workers (CHWs) and their subsequent engagement to raise awareness and scale-up DR screening for communities throughout Fiji. As part of a programme to reduce the incidence of avoidable blindness due to diabetes amongst people living in the Pacific, DR training for primary level nurses was developed and implemented. As these primary level nurses were already inundated by clinical duties and competing health priorities, a shifting of the task was proposed to engage the CHWs who would instead educate communities on diabetes and DR and make referrals for DR screening. A one-day DR awareness training was developed and implemented by the Pacific Eye Institute with funding from the Fred Hollows Foundation New Zealand. At the end of the DR programme in 2019, the team had achieved their target and trained a total of 823 CHWs giving an 81.32% coverage of the total 1012 registered CHW in the MHMS register. Anecdotal evidence showed a spike in DR referrals and screenings recorded at health facilities. Three key themes emerged related to the involvement of CHWs which include engagement of CHWs, benefits of the engagement, and health system-related challenges. The use of CHWs who are already integrated into the health system was considered a sustainable intervention to strengthen diabetes and DR services at the primary level of care, particularly if it involves community awareness, health education, and health services facilitation The future of the CHWs will depend on their being integrated more systematically into local health services with strengthened management and supervision.We acknowledge Fred Hollows Foundation New Zealand for granting this project

Occupational stress and burnout among young surgeons: a review

A surgeon's lifestyle is a multifaceted commitment that revolves around their workplace, physical, personal, emotional, and communal domains. Surgical training programs are competitive and challenging to match and provide a sense of gratification among medical school trainees. But they also report a much higher level of burnout when compared to their peers from other specialities. Workplace burnout has been a scorching issue since the COVID pandemic broke out in 2019. We did this review to understand the factors leading to workplace burnout, identify any East-West differences, and find possible solutions. We also tried to find the role of COVID-19 in worsening occupational stress among surgeons. We searched the PubMed and SCOPUS databases for studies between January 2000 to January 2022 on burnout, well-being, wellness, and practice improvement among surgeons. The search included studies on COVID-19 that were available either as full-text papers or abstracts. Burnout has affected younger surgeons owing to loss of professional control, inefficient work-life balance, administrative burdens, medico-legal problems, and the competitive nature of the job and tiresome training programs. Burnout is more common in South-Asian countries. Workplace stressors, including long hours and difficult interactions with co-workers, are linked to greater levels of burnout. The COVID-19 pandemic has only made matters worse

Therapeutic approaches to drug targets in atherosclerosis

AbstractNon-communicable diseases such as cancer, atherosclerosis and diabetes are responsible for major social and health burden as millions of people are dying every year. Out of which, atherosclerosis is the leading cause of deaths worldwide. The lipid abnormality is one of the major modifiable risk factors for atherosclerosis. Both genetic and environmental components are associated with the development of atherosclerotic plaques. Immune and inflammatory mediators have a complex role in the initiation and progression of atherosclerosis. Understanding of all these processes will help to invent a range of new biomarkers and novel treatment modalities targeting various cellular events in acute and chronic inflammation that are accountable for atherosclerosis. Several biochemical pathways, receptors and enzymes are involved in the development of atherosclerosis that would be possible targets for improving strategies for disease diagnosis and management. Earlier anti-inflammatory or lipid-lowering treatments could be useful for alleviating morbidity and mortality of atherosclerotic cardiovascular diseases. However, novel drug targets like endoglin receptor, PPARα, squalene synthase, thyroid hormone analogues, scavenger receptor and thyroid hormone analogues are more powerful to control the process of atherosclerosis. Therefore, the review briefly focuses on different novel targets that act at the starting stage of the plaque form to the thrombus formation in the atherosclerosis

Research Article A new Informatics Framework for Evaluating the Codon Usage Metrics, Evolutionary Models and Phylogeographic reconstruction of Tomato yellow leaf curl virus (TYLCV) in different regions of Asian countries

Tomato yellow leaf curl virus (TYLCV) is a major devastating viral disease, majorly affecting the tomato production globally. The disease is majorly transmitted by the Whitefly. The Begomovirus (TYLCV) having a six major protein coding genes, among them the C1/AC1 is evidently associated with viral replication. Owing to immense role of C1/AC1 gene, the present study is an initial effort to elucidate the factors shaping the codon usage bias and evolutionary pattern of TYLCV-C1/AC1 gene in five major Asian countries. Based on publically available nucleotide sequence data the Codon usage pattern, Evolutionary and Phylogeographic reconstruction was carried out. The study revealed the presence of significant variation between the codon bias indices in all the selected regions. Implying that the codon usage pattern indices (eNC, CAI, RCDI, GRAVY, Aromo) are seriously affected by selection and mutational pressure, taking a supremacy in shaping the codon usage bias of viral gene. Further, the tMRCA age was 1853, 1939, 1855, 1944, 1828 for China, India, Iran, Oman and South Korea, respectively for TYLCV-C1/AC1 gene. The integrated analysis of Codon usage bias, Evolutionary rate and Phylogeography analysis in viruses signifies the positive role of selection and mutational pressure among the selected regions for TYLCV (C1/AC1) gene
