Introduction: Temporomandibular joint (TMJ) hypermobility affects broad demographic, challenging the efficacy of traditional treatments. The aim of this study is to investigate therapeutic potential of autologous blood injections (ABI) vs dextrose prolotherapy in rabbit model, through detailed histopathological & radiological analyses. Material and Methods: After ethical approval from the institutional committee, a hypermobile joint model was established in rabbits through surgery affirmed by MRI. Subsequently, rabbits were randomly divided into two groups i.e. ABI and dextrose solution. In each group, one joint was designated as control, treated with saline. Following surgical induction of TMJ hypermobility, treatments were administered, & outcome was assessed through histological examination for fibrosis grading & CD68 staining for macrophage infiltration. Results: The ABI group exhibited a higher fibrosis grade (> 75% in 50% of joints) & stronger CD68 staining, indicating a significant fibrotic response & macrophage infiltration compared to dextrose group. In contrast, control joints displayed no fibrosis grades & negative CD68 staining. Conclusion: The study highlights both ABI & dextrose prolotherapy elicit significant fibrotic responses in treating TMJ hypermobility, indicating their therapeutic mechanisms. ABI in particular, triggers more marked inflammatory reaction, underscoring its potential efficacy. Further evaluation is essential to understand its clinical significance and applicability in managing TMJ disorders. © The Association of Oral and Maxillofacial Surgeons of India 2025.
Kite String (Manjha) Injuries Among Children: Single Center Experience Over Four Years
(Springer, 2023) Preeti Tiwari; Nishtha Chauhan; Rahul Patel; Rathindra Nath Bera; Vaibhav Pandey
We reviewed hospital records for kite-string injuries among children over four years (2017–2022). Of 42 affected children, mortality was 9.5%. The mean (SD) Pediatric Trauma Score (PTS) was 8.02 (2.66), with passively involved children facing greater severity [mean (SD) PTS, 5.58 (2.23)]. Kite-string injuries, alarmingly, endanger even bystanders, urging stricter preventive strategies. © 2023, Indian Academy of Pediatrics.
Modeling the effects of insecticides and external efforts on crop production
(Vilnius University Press, 2021) A.K. Misra; Rahul Patel; Navnit Jha
In this paper a nonlinear mathematical model is proposed and analyzed to understand the effects of insects, insecticides and external efforts on the agricultural crop productions. In the modeling process, we have assumed that crops grow logistically and decrease due to insects, which are wholly dependent on crops. Insecticides and external efforts are applied to control the insect population and enhance the crop production, respectively. The external efforts affect the intrinsic growth rate and carrying capacity of crop production. The feasibility of equilibria and their stability properties are discussed. We have identified the key parameters for the formulation of effective control strategies necessary to combat the insect population and increase the crop production using the approach of global sensitivity analysis. Numerical simulation is performed, which supports the analytical findings. It is shown that periodic oscillations arise through Hopf bifurcation as spraying rate of insecticides decreases. Our findings suggest that to gain the desired crop production, the rate of spraying and the quality of insecticides with proper use of external efforts are much important. © 2021 Authors.

Modeling the effects of insects and insecticides on agricultural crops with NSFD method
(Springer, 2020) A.K. Misra; Navnit Jha; Rahul Patel
Worldwide, agricultural crops are vulnerable to insects. During the crop season, insects target plants especially leaves for food and thus harm the agricultural crops. This reduces agricultural production and therefore effects the economy of farmers. To overcome this problem, nowadays farmers spray insecticides on crops to reduce the density of insects. In this paper, a nonlinear mathematical model is formulated to assess the impacts of insecticides on insects and crop production. In the modeling process, it is presumed that the agricultural crops grow logistically and the growth rate of the insect population wholly depends on the agricultural crops. As the excess use of insecticides on crops is harmful to agricultural farms and human health, therefore we have made an assumption that the spray rate of insecticides to kill insects is proportional to the density of insects. The feasibility of all the possible equilibria is shown and their stability properties are discussed. Keeping in mind the nonlinearity of the formulated model and different time scales of the participating variables, we have constructed a non-standard finite difference scheme by discretizing the system. It is shown that the proposed numerical scheme is convergent with second-order accuracy. Numerical simulation by using our computational scheme has been also presented to support the analytical findings. Using the approach of global sensitivity analysis, we have identified the key parameters for the formulation of effective control strategies necessary to combat the insect population and increase the crop production. Our findings suggest that to gain the desired crop production, the rate of spraying and the quality of insecticides are much important. © 2020, Korean Society for Informatics and Computational Applied Mathematics.
Modeling the Effects of Insects and Insecticides with External Efforts on Agricultural Crops
(Springer, 2024) A.K. Misra; Navnit Jha; Rahul Patel
In this paper, we propose a continuous dynamical model along with its discretized system to increase the agricultural crop production using some external efforts in presence of insects and insecticides. It is assumed that agricultural crops grow logistically and its growth deplete due to insect population, which is wholly dependent on crops. Farmers use insecticides to kill insects to protect the crop and its excessive use is hazardous to human health and therefore it is assumed that insecticides are used proportional to the density of insects. To increase field’s growth potential, we presumed that some efforts (e.g. seed selection, use of fertilizers, proper water drainage, etc.) are applied proportional to the difference between carrying capacity and actual production. The quantitative features of the nonlinear crop production model is examined by a coherent non-standard finite difference scheme (NSFDS) in the absence of theoretical solution values. This scheme is formulated by discretizing the model system and renormalizing the denominator of derivatives of continuous system. Convergence analysis of the new NSFD scheme is described in detail. A graphical layout by computer-assisted numerical results is introduced to observe the effects of external efforts on production of agricultural crops. © 2020, Foundation for Scientific Research and Technological Innovation.
