Plasma cell gingivitis (PCG) is a diagnostic dilemma for clinicians. It is also referred to as atypical gingivostomatitis, idiopathic gingivostomatitis, allergic gingivostomatitis, and plasma cell ...gingivostomatitis which are characterized by bright fiery red gingiva with spontaneous bleeding on slight provocation. It is often confused with inflammatory gingival enlargement, erythematosus lichen planus, and other lesions. One such rare and benign entity is discussed in this article and managed after thorough clinical, radiological, histopathology, immunohistochemistry analysis.
Gingival recession is defined as the apical migration of gingival margin below cemento-enamel-junction. Exposed root surfaces can lead to hypersensitivity, increased plaque accumulation, poor ...aesthetics, root caries, non-carious cervical lesions (NCCL) and attachment loss. Surgical root coverage techniques include pedicle grafts, such as coronally advanced flap, rotational lateral positional flaps (LPF), double papilla flaps, free grafts such as sub epithelial connective tissue grafts and free gingival grafts and guided tissue regeneration using barrier membranes. Lateral positioned flap is commonly used to cover isolated denuded roots with adequate vestibule depth and donor tissue adjacent to the recession area. LPF offers single surgical site, preserved blood supply to the flap and excellent aesthetics due to harmonization of color. Various modifications of the laterally sliding flap have been proposed to reduce the risk of post-surgical recession at the donor tooth site, but the reported root coverage predictability was quite low. This case report demonstrates the management of class II Millers recession, using 'Laterally moved, Coronally advanced flap'. The case demonstrated 100% root coverage at 6 months follow up.

Acute myelogenous leukemia (AML) frequently relapses after complete remission (CR), necessitating improved detection and phenotypic characterization of treatment-resistant residual disease. In this ...work, we have optimized droplet digital PCR to broadly measure mutated alleles of recurrently mutated genes in CR marrows of AML patients at levels as low as 0.002% variant allele frequency. Most gene mutations persisted in CR, albeit at highly variable and gene-dependent levels. The majority of AML cases demonstrated residual aberrant oligoclonal hematopoiesis. Importantly, we detected very rare cells (as few as 1 in 15,000) that were genomically similar to the dominant blast populations at diagnosis and were fully clonally represented at relapse, identifying these rare cells as one common source of AML relapse. Clinically, the mutant allele burden was associated with overall survival in AML, and our findings narrow the repertoire of gene mutations useful in minimal residual disease-based prognostication in AML. Overall, this work delineates rare cell populations that cause AML relapse, with direct implications for AML research directions and strategies to improve AML therapies and outcome.
Solar energy is a significant energy source of outstanding sustainability, mainly used for heating and power production. There are numerous energy storage materials through which the performance ...enhancement of different solar heating systems is possible. In the present work, three different sensible heat storage materials, such as blackened pebbles, small pieces of masonry bricks, and small aluminium balls, have been experimentally studied for their thermal storage capacity inside a hot box cooker. All these materials have been used over the cooking plate of the tested cookers. Only three configurations have been developed to perform the stagnation and sensible heat tests. Notably, the authors have focused on a low-cost solution to enhance the thermal efficiency of a box cooker using sensible heat storage materials, especially for people from remote or rural areas. Even, a less educated consumer can easily apply the suggested technique to a box cooker through the Do-It-Yourself method. Results of the cooking trials have been found in favour of consumers and show the appropriateness of low-cost energy storage materials. These results also indicate a possibility of adopting all the tested models, mainly the cooker with aluminium balls, which is the best-configured cooker. This cooker has a thermal efficiency of about 59.61 %, cooking power of about 75.21 W, and thermal storage capacity of around 09 h/day. The estimated cost is approximately $47.06 for the best-configured cooker and its payback period is about 3.11 years.
•Three different low-cost sensible energy materials are tested for solar cooking trails.•All the modified cookers have excellent cooking performance and found capable for evening cooking.•All the modifications can be made to the cooker by Do-It-Yourself by its users at low-cost.•The best model has thermal efficiency about 59.61 % and cooking power about 75.21 W.
The rapid transmission of COVID-19 infection around the world in a brief timeframe has caused an exponential decline in street traffic and other industrial activities in various parts of the world. ...The confined human collaboration with the nature at the time of this emergency has shown up as an advantage for Mother Nature after COVID-19 flare because the air present in the atmosphere and water flowing in river streams is upgrading and untamed life is blossoming. India, being consistently seen as the center of contamination due to a tremendous population, overwhelming road traffic and industries which contribute to heavy pollution prompting rise in air quality index for almost all the big cities of the country. However, after the announcement of lockdown because of COVID-19, the air quality begun to upgrade and other environmental variables, for example, water quality in streams and waterways have begun offering a positive hint towards restoration. This review gives a brief knowledge on the structure and genomic organization of novel coronavirus as well as it focuses on alterations in air and water quality along with its environmental consequences at specific locations of the country during lockdown due to this pandemic circumstance.
•Development of a special purpose FBG sensors.•In-situ measurement of resin pressure in curing composites.•A coupled multiphysics process modelling of composites curing.
Resin pressure distribution ...of a curing Glass/Epoxy prepreg lay-up is the key parameter that controls the strength, stiffness and void nucleation of the cured composite part. It is vital to monitor and control the resin movement of curing laminate to optimize its quality in any manufacturing process. In this paper, design of a Fiber Bragg grating (FBG) based device, capable of measuring in-situ resin pressure of a curing lay-up is presented. This device uses the principle of differential pressure in liquids. The device was calibrated using a water column, and a pressure sensitivity of 1.636×10−2MPa−1 was yielded. FBG responds linearly with the rise of hydrostatic pressure in the water column. An excellent agreement was found between experimental and theoretical results. This device was used to monitor the resin pressure in a curing prepreg composite lay-up. The measured liquid resin pressures were also compared to the resin pressure obtained from a coupled multi-physics numerical simulation. The presented sensor is useful for in-situ pressure measurements, especially for high temperature and low or zero bleed curing of composites, for example, out of autoclave curing.
