Yadav Arun Kumar,Ahsan Amra,Kumar Vijay 대한청각학회 2023 Journal of Audiology & Otology Vol.27 No.1

Background and Objectives: Severe to profound hearing loss impacts the capacity for verbal communication as well as the social, emotional, and overall quality of life; however, the association between socio-emotional rehabilitation and post-hearing aid use is not widely explored. This study aimed to investigate the socio-emotional change in post-hearing aid fitted individuals with severe to profound hearing loss.Materials and Methods: A total of 60 individuals comprised of 15 females and 45 males with severe to profound hearing loss within the age range of 40-60 years (mean age and standard deviation of 53.4±6.1), participated in this study. Participants were divided into two categories with a 10-year age interval i.e., 40–50 and 51-60 years. These participants were equally divided into hearing aid user (HAU) and non-hearing aid user (NHAU) groups. The hearing handicapped inventory for the adults-short version (HHIA-S) adapted from Weinstein & Ventry (1983) was used in this study.Results: The mean social score of all the participants was significantly higher than the mean emotional score. However, no such advantage was observed between the HAU and NHAU groups. The mean social score of females in the HAU category was significantly higher than males. The mean social and emotional scores were also compared across two age categories in the age range of 40-50 and 51-60 years and revealed no significant difference between mean social and emotional score across the age categories (<i>p</i>=0.026).Conclusions: In individuals with severe to profound hearing loss, social rehabilitation occurs quicker than emotional. In the HAU group, socialization occurred faster in females than males. These findings suggest that a customized counselling should be developed for the social and emotional wellbeing as these two parameters improve distinctly.

Background and Purpose The purpose of this meta-analysis was to determine the precise association between beta-2 adrenergic receptor (β2AR) polymorphism and Ischemic stroke. Methods Published case control studies on association between β2AR and ischemic stroke were searched from electronic databases. Pooled Odds ratio and 95% Confidence interval were calculated by using software RevMan version 5.2. Results A total of three studies involving 1,642 cases and 1,673 controls, which were published from 2007 to 2014, were subjected to meta-analysis for allelic association and 518 cases and 510 controls for genotypic association. Pooled analysis of two studies for genotypic association suggested that subjects carrying Gln27Glu polymorphism of β2AR had an increased risk for Ischemic stroke under recessive model (OR 2.09; 95% CI; 1.20 to 3.64) and under dominant model (OR 1.47; 95% CI 1.14 to 1.90). Pooled analysis of three studies for allelic association showed a significantly higher Glu27 allele of β2AR in the patients with ischemic stroke (OR 1.58; 95% CI; 1.38 to 1.81). Conclusions The present meta-analysis suggests that Gln27Glu polymorphism of β2AR gene is associated with increased risk for ischemic stroke.

Gupta, Rakesh Kumar,Patel, Amit Kumar,Shah, Niranjan,Choudhary, Arun Kumar,Jha, Uday Kant,Yadav, Uday Chandra,Gupta, Pavan Kumar,Pakuwal, Uttam Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.11

Reactive oxygen species (ROS), highly reactive molecules, are produced by living organisms as a result of normal cellular metabolism and environmental factors, and can damage nucleic acids and proteins, thereby altering their functions. The human body has several mechanisms to counteract oxidative stress by producing antioxidants. A shift in the balance between oxidants and antioxidants in favor of oxidants is termed as "oxidative stress". Paradoxically, there is a large body of research demonstrating the general effect of oxidative stress on signaling pathways, less is known about the initial and direct regulation of signaling molecules by ROS, or what we term the "oxidative interface." This review focuses on the molecular mechanisms through which ROS directly interact with critical signaling molecules to initiate signaling in a broad variety of cellular processes, such as proliferation and survival (MAP kinases and PI3 kinase), ROS homeostasis, and antioxidant gene regulation (Ref-1 and Nrf-2). This review also deals with classification as well as mechanisms of formation of free radicals, examining their beneficial and deleterious effects on cellular activities and focusing on the potential role of antioxidants in preventing and repairing damage caused by oxidative stress. A discussion of the role of phytochemical antioxidants in oxidative stress, disease and the epigenome is included.

Powdery mildew of Indian mustard (Brassica juncea), caused by Erysiphe cruciferarum, is emerging as ma- jor problem in India. All the Indian mustard cultivars presently grown in India are highly susceptible to pow- dery mildew and so far no resistance source has been reported. In this study, with an aim to identify resistant source, 1,020 Indian mustard accessions were evaluated against E. cruciferarum PMN isolate, at Wellington, The Nilgiris, Tamil Nadu, India under natural hot spot conditions. The study identified one accession (RDV 29) with complete resistance against E. cruciferarum PMN isolate for the first time, which was consistent in five independent evaluations. Genetic analysis of F1, F2 and backcross populations obtained from the cross RSEJ 775 (highly susceptible) × RDV 29 (highly resistant) for two season revealed that the resistance is governed by two genes with semi-dominant and gene dosage effect. Further, a new disease rating system using six scales (0, 1, 2, 3, 4, and 5) has also been proposed in this study to score powdery mildew based on progress of fungal growth in different plant parts of the F2 population. The outcome of this study viz. newly identified powdery mildew-resistant Indian mustard accession (RDV 29), information on inheritance of resistance and the newly developed disease rating scale will provide the base for development of powdery mildew-resistant cultivars of Indian mustard.

This study reports the toxicological evaluation findings of Cyperus compressus Linn., (Cyperaceae), whose root decoction is used in India to treat the intestinal helminthic infestations. The acute oral toxicity (AOT) of C. compressus root extract (CRE) was conducted in Swiss mice, following OECD guidelines 407. The sub-acute toxicity study of CRE was undertaken in Wistar rats, using three doses viz., 175, 350 and 700 mg/kg, involving haematological, biochemical and transmission electron microscopy (TEM) parameters. AOT study revealed the median lethal dose of CRE to be above 2000 mg/kg. The sub-acute study of CRE revealed elevated levels of serum glutamic oxaloacetic transaminase in male rats, only in high extract-treated group, but the serum glutamic pyruvic transaminase was found to be elevated both in male and female animals. TEM studies of kidney and liver of animals also revealed considerable deformities in the nucleus and mitochondria in the form of damages to nuclear membrane, cristae and to double layered membrane of mitochondria, only in the high-extract treated group of animals. The root decoction of C. compressus show presence of toxicity in the highest dose tested animals. Therefore, the use of this plant extract against intestinal helminthiasis raises concerns about its safety.

Polypyrrole Coated Textiles as Photothermal Material for Interfacial Solar Evaporation

Subhankar Maity,Madhu Yadav,Arun Kumar Patra 한국섬유공학회 2023 Fibers and polymers Vol.24 No.10

Solar evaporation is a primitive skill that has regained tremendous attention because of the sufficiency of solar energy and water sources on Earth. Textile materials are suitable for solar evaporation because of their porous structure with micro-channels, promoting moisture wicking, low heat conductivity and good solar absorptivity. The absorptivity and solar evaporation performance of textile materials can be improved by coating a suitable photothermal material like polypyrrole (PPy). In the present research, PPy is coated onto various woven and spunlace nonwoven fabrics by in-situ chemical polymerization to develop functional textiles for efficient photothermal conversion. Optical and electron microscopy studies confirms that the polymerization proceeded smoothly, resulting in the formation of a uniform layer of PPy around the individual fibres and as well as trapped in fibre interstices. PPy-coated 100% viscose spunlace nonwoven fabric (with 22.3% PPy add-on) shows maximum light absorbance ability (K/S value 7.543) exhibiting the rise of surface temperature upto 71 °C after exposure of 5 min to sunlight. The maximum water evaporation rate is obtained in case of PPy coated 100% viscose nonwoven (3.343 kgm-2 h-1), followed by 50:50 blended polyester/viscose nonwoven (2.400 kgm-2 h-1), 100% polyester nonwoven (1.683 kgm-2 h-1) and cotton woven fabrics (1.867 kgm-2 h-1). FTIR studies reveal significant intermolecular interaction (-H bonds) between cellulosic molecules and PPy. Such PPy-coated textile material can be a potential candidate for water desalination and purification to address the issue of water scarcity by effective utilization of solar radiation.

Erectile dysfunction and cancer: current perspective

Renu Madan,Chinna Babu Dracham,Divya Khosla,Shikha Goyal,Arun Kumar Yadav 대한방사선종양학회 2020 Radiation Oncology Journal Vol.38 No.4

Erectile dysfunction (ED) is one of the major but underreported concerns in cancer patients and survivors. It can lead to depression, lack of intimacy between the couple, and impaired quality of life. The causes of erectile dysfunction are psychological distress and endocrinal dysfunction caused by cancer itself or side effect of anticancer treatment like surgery, radiotherapy, chemotherapy and hormonal therapy. The degree of ED depends on age, pre-cancer or pre-treatment potency level, comorbidities, type of cancer and its treatment. Treatment options available for ED are various pharmacotherapies, mechanical devices, penile implants, or reconstructive surgeries. A complete evaluation of sexual functioning should be done before starting anticancer therapy. Management should be individualized and couple counseling should be an integral part of the anticancer treatment.
