Chauhan Bhushan,Arya Shantanu,Chauhan Komal 대한청각학회 2023 Journal of Audiology & Otology Vol.27 No.1

Background and Objectives: Tinnitus, or ear ringing, involves impulsive and spontaneous activity in the auditory neurons. Its prevalence is high in the elderly, but 10%–15% of adults suffer from tinnitus, affecting their quality of life. Therefore, this study aimed to evaluate the efficacy of <i>Ginkgo biloba</i> administered singly and in combination with antioxidants in tinnitus patients.Subjects and Methods: Patients were randomly allocated to Placebo (T0, n=22), Treatment 1 (T1, n=24), and Treatment 2 (T2, n=23) groups. The patients were educated on the study’s methodology and were instructed to visit at 0, 4, 8, 12, and 14 weeks. The placebo group received starch capsule supplements. Conversely, the treatment groups received <i>Ginkgo biloba</i> (60 mg twice a day) singly and in combination with antioxidants. We enrolled 69 patients aged 40–70 years (41 men, 28 women). The Tinnitus Handicap Index (THI), Visual Analogue Score (VAS), and Short Form 36 (SF-36) Health Scores were determined pre- and post-treatment at each visit.Results: Supplementation of <i>Ginkgo biloba</i>, along with antioxidants, provided marked improvement (<i>p</i><0.05) in post-treatment THI and VAS scores in the T2 group compared to those in the T1 and T0 groups. The greatest (<i>p</i><0.05) percent difference was observed in the pre- and post-treatment THI (-36%) and VAS scores (-22.6%) of T2 patients. Likewise, the SF-36 scores improved significantly (<i>p</i><0.05) in the T2 group in varied parameters.Conclusions: <i>Ginkgo biloba</i>, along with antioxidants, can be a promising therapy for tinnitus patients, providing marked improvement in THI, VAS, and SF-36 scores.

A STUDY OF THE RIGHT LOCAL GENERAL TRUNCATED M-FRACTIONAL DERIVATIVE

Chauhan, Rajendrakumar B.,Chudasama, Meera H. Korean Mathematical Society 2022 대한수학회논문집 Vol.37 No.2

We introduce a new type of fractional derivative, which we call as the right local general truncated M-fractional derivative for α-differentiable functions that generalizes the fractional derivative type introduced by Anastassiou. This newly defined operator generalizes the standard properties and results of the integer order calculus viz. the Rolle's theorem, the mean value theorem and its extension, inverse property, the fundamental theorem of calculus and the theorem of integration by parts. Then we represent a relation of the newly defined fractional derivative with known fractional derivative and in context with this derivative a physical problem, Kirchoff's voltage law, is generalized. Also, the importance of this newly defined operator with respect to the flexibility in the parametric values is described via the comparison of the solutions in the graphs using MATLAB software.

The Role of Yoga Intervention in the Treatment of Allergic Rhinitis: A Narrative Review and Proposed Model

Chauhan, Ripudaman Singh,Rajesh, S.K Cellmed Orthocellular Medicine and Pharmaceutical 2020 셀메드 (CellMed) Vol.10 No.3

Allergic Rhinitis (AR) is an IgE (immunoglobin-E) mediated inflammatory condition of upper respiratory tract; main clinical features involve runny nose, sneezing, nasal obstruction, itching and watery eyes. AR is a global problem and has large variations in incidences, currently affects up to 20% - 40% of the population worldwide. It may not be a life-threatening disease per se but indisposition from the condition can be severe and has the potential to adversely affect the daily functioning of life. Classical yoga literature indicates that, components of yoga have been used to treat numerous inflammatory conditions including upper respiratory tract. A few yoga intervention studies reported improvement in lung capacity, Nasal air flow and symptoms of allergic rhinitis. This review examined various anti-inflammatory pathways mediated through Yoga that include downregulation of pro-inflammatory cytokines and upregulation of anti-inflammatory cytokines. The hypothalaminic-pitutary-adrenal (HPA) axis and vagal efferent stimulation has been reported to mediate anti-inflammatory effect. A significant reduction is also reported in other inflammatory biomarkers like- TNF-alpha, nuclear factor kappa B (NF-κB), plasma CRP and Cortisol level. Neti, a yogic nasal cleansing technique, reported beneficial effect on AR by direct physical cleansing of thick mucus, allergens, and inflammatory mediator from nasal mucosa resulting in improved ciliary beat frequency. We do not find any study showing effect of yoga on neurogenic inflammation. In summary, Integrated Yoga Therapy may have beneficial effect in reducing symptoms and improving quality of life for patients with allergic rhinitis. Yoga may reduce inflammation through mediating neuro-endocrino-immunological network. Future studies are needed to explore the mechanism how yoga might modulate immune inflammation cascade and neurogenic inflammation at the cellular level in relevance to allergic rhinitis; the effects of kriyas (yogic cleansing techniques) also need to be evaluated in early and late phase of AR. So the proposed model could guide future research.

Role of Devnagari and Persian Script in Hindi-Urdu Controversy: A Historical Perspective

( Chauhan Karan Singh ) 한국인도학회 2011 印度硏究 Vol.16 No.1

Controversy regarding the language of the so-called ``Hindustani`` area has been an important issue throughout British period which engulfed the Indian freedom movement. Hindi or ``Hindui`` was the original form adopted and mentioned as such by the earliest of writers of Hindi. Later, word Urdu came into use to denote the same language called Hindi or Hindui, but with a Persian tilt. The common people continued to regard both forms as one language. Due to Moghal rule, Hindi and later Urdu written in Persian script became the official language of governance. When Britishers came to India they found a very interesting phenomena with regard to language and scripts pravelent in northern Hindi belt. Although the spoken language of the people was one, but it was written in a script, imposed from outside. They tried to confirm the real position by doing various language and script surveys and came to the conclusion that it would be better for communication and understanding if beside Persian script, ``Nagari`` script is introduced in Government offices and courts etc. This angered the Muslim community who used to be in an advantageous position with Persian script. Although, language question was never a controversial issue among the common people of this area but due to the two different scripts, it got associated with communal feelings. The emergence of Sanskritized Hindi and Persianized Urdu was the direct outcome of this communal divide. Britishers tried to not only placate this but took full advantage of the issue for dividing people on communal lines. To create communal unity within freedom struggle, Gandhi Ji tried to bring ``Hindustani`` into focus which represent the mix of both spoken Hindi and Urdu. He advocated one common language for both the communities which can be written either in Nagari or Persian script. It attracted lot of criticism from both sides. In such a charged atmosphere the question of National language or a National script became more and more controversial. Progressive cultural movement, being the most important literary movement in all Indian Languages, where both Hindi and Urdu writers worked together, tried to understand and solve the language and script problem. On the basis of its analysis and conclusions it mendated that Hindi written in Devnagari script should be the national language of the country and Urdu written in Persian should be regarded as close associate of it. Later, when Indian constitution was framed and implemented, in article 343 regarding the Official language of the Union it was written that ``the official language of the Union shall be Hindi in Devnagari script.``

The Performance and Emissions Analysis of a Multi Cylinder Spark Ignition Engine with Gasoline LPG & CNG

Chauhan, Bhupendra Singh,Cho, Haeng-Muk The Korean Institute of GAS 2011 한국가스학회지 Vol.15 No.4

The introduction of alternative fuels is beneficial to overcome the fuel shortage and reduce engine exhaust emissions. LPG and CNG are relatively clean fuel and considered as most promising alternative automotive fuels worldwide because of its emission reduction potential and lower fuel price compared to gasoline. Now a day’s adaptation of dual fuel approach is the growing as common trend. The two fuels can be successfully implemented with existing gasoline engine with little modification. The present study was done to analyze the performance and emissions analysis of a multi cylinder spark ignition engine fuelled with the benefits of CNG and LPG aseffective alternate automotive fuels by simply using them in an unmodified petrol engine. The test results indicate, the energy content of CNG and LPG is the most limiting factor in acceptance for fuel economy and performance reasons. Thermal efficiency was high for CNG lowest for gasoline and LPG between the two. BSFC, CO and HC were low and NOx was high for CNG and low for gasoline, LPG lies between the two.
