Abstract: Autism spectrum disoroders (ASD) are heritable neurodevelopment disorders that occurring 1 to 2 % children , generally below the age of three, with differing symptoms and severity (Balaji and Sinha, 2018).ASD is characterised by impaired social interactions, impaired verbal and non-verbal communication, and the appearance of unusual stereotypic, and communication, and the appearance of unusual stereotypic , and sometimes self-injurious , behaviours factors, such as genetic aberrations, environmental insults , and social factors, contribute to the development of autism (Pragnya et al, 2014).The etiology of autism increases oxidatives stress, hyperserotoanaemia, and loss of Purkinje cell integrity in the cerebellum (Balaji and Sinha, 2018).Neurotransmitters are endogeneous chemicals, so called as chemical transmitters or chemical messengers binding neurons that play a key role in normal brain development , memory, motor activity, and behaviour regulation development ( cetlin et al., 2015).Several studies have been conducted in humans on this subject reporting neurotransmitters , corresponding mostly to the pathogenesis of ASD and are serotonergic, GABAergic and glutamatergic systems.

Abstract: Agricultural practices have increased in the last years to meet the population’s food demands. To this end, two approaches have been used: (i) expansion, by the use of new land, usually in environmentally fragile areas (II) intensification, by increasing the productivity of cultivated land. Intensification of agricultural practices involves the use of high amounts of fertilizers and pesticides. The agrochemicals applied can reach freshwater bodies of drift, leaching of runoff, affecting non target organisms (Amoros et al., 2007; Sasal eta l., 2015).There is a growing concern about the pollution of continental water bodies by agrochemicals , because their species and habitat diversity as well as their ecosystem services are declining (Ervin, 2009).Therefore there is an urgent need to study the effects of agrochemicals on the aquatic biota and the processes that support environmental biodiversity and its functionality.

Abstract: Globally, cancer cases have been estimated to rise to 19.3 million and approximately 10 million deaths in the year 2020,as per the reports of GLOBOCAN 2020 generated by the International Agency for Research on Cancer (Sung et al., 2021).Similarly, as the Cancer Statistics Report-2020 of India produced by the National Cancer Registry Programme, India the estimated number of cancer patients in India was 1,392,179 for the year 2020(Mathur et al. 2020) .The term cancer incorporate multiple variants. Among them, the seriousness of lung cancer has increased multifold in the recent past. Lung cancer is the largest cause of cancer death despite advancements in our understanding of risk; progression, immunological control, and therapeutic choices (Bade and Dela Cruz, 2020).According to the above report, there were 2.09 million cases reported and 1.76 million deaths in 2018 due to lung cancer.

Abstract: Endocrine-disrupting chemicals are compounds that mimic, block or interfere with the function of hormones in the body’s endocrine system (Schug et al, 2011). Bisphenol A (BPA) is one among them which serve as plasticizer in the production of polycarbonate plastics, epoxy resin and unsaturated polystyrene. The usage of BPA has progressively increased worldwide due to its extensive application in manufacturing of daily necessities such as plastic bottles, food packaging, thermal paper, electronic equipment and medical appliances (Vandenberg et al., 2007). Humans can be exposed to BPA via ingestion, inhalation and skin contact at micrograms per kg of body weight daily. PA has demonstrated, multiple adverse effects on laboratory animals, in term of neurological development, behavioural changes, reproduction and lead to carcinogenesis (Inadera,2015).

Abstract: The pink bollworm , Pectinophora gossypiella, has become a significant production constraint on Bt cotton in India. This problem is unique to India because the pest has developed multi-fold resistance to Cry toxins in many Indian populations but not in other countries. Most India populations have developed multifold resistance to Cry 1 Ac and Cry 1Ac+ Cry 2 Ab toxins. Year-round cultivation of long-duration Bt cotton hybrids on a large scale has a pronounced impact on the incidence. Also discussed other factors responsible for the occurrence of pink bollworm on Bt cotton in India. Insecticide Resistance Management (IRM) strategies implemented by different cotton-growing countries globally; the USA, India and China had a significant impact on the interaction of pink bollworm on Bt cotton.

Subject: Utilization of biomolecules as fuel energy and their physiological mechanism during migration in birds
Keywords: Birds, Bio molecules, Energy, Fasting, Fattening, Metabolites, Migration
Abstract: Migratory birds undergo physiological and behavioural changes to fuel their high energy demanding migratory flights. They increase their food intake as part of the preparation for migration which results in increase in their body mass. Ft, carbohydrates and protein acquired from food are stored mainly in the adipose tissue (triglycerides), muscle and liver (Glycogen) and body organs (protein) in migratory birds. These stored foods ac as fuels to support birds’ migratory flights. Dietary carbohydrates and lipids not only provide energy for migration but also help in fattening as carbohydrates can be converted into fat and lipids which can be stored. Lipolysis of adipose –stored fats leads to the production of triglycerides, fatty acids and glycerol, which provide energy for migration. Fats are depleted after long migratory flights and replenished during refuelling at the stopover sites. Being chemically reduced and hydrophobic in nature, fat releases more energy on oxidation as compared to carbohydrate and protein. Due to its high energy-yielding nature, that fat is the preferred fuel to support migration in birds. Migratory birds deposit fat and deplete it during the course of migration. Though, the stored fat act as the primary source of energy, metabolism of body protein also provides energy for migratory flights. Uric acid in plasma is elevated when protein is catabolised .The metabolism of carbohydrate, stored as glycogen in liver and muscle in migratory birds, produce glucose which also fuels migration. Glucose in migratory is maintained at stable levels in plasma and it provides energy only for a flight of short period.

Subject: Study of decadal variations in width and mangrove cover of the Thane Creek, Maharashtra, India, using remote sensing
Keywords: Creek, decadal variations, mangrove cover, mudflats, remote sensing.
Abstract: The present study depicts decadal variations in the area, width and mangrove cover of Thane Creek, Maharashtra, India, using the remote sensing technique. The study is significant because the Creek has lush-green mangrove cover on its vast intertidal region and considerable urban developmental activities are occurring around it. Landsat datasets were used for different years from 1972 to 2014 and Sentinel 2A satellite data were used for the year 2020. To understand the variations in width from mouth to upstream, the Creek was divided into three zones, viz. mouth, middle and upstream. For mangrove cover estimation, supervized classification analysis was used for images from 2005 to 2014, while object-based image classification analysis with multispectral resolution was used for images from 2020. From the results, it can be confirmed that there is an overall increase in the spatial extent of mangroves and a reduction in the width of Thane Creek. The study also shows that creek width had decreased by 1.15 km at the mouth and 0.08 km at the upstream end from 1972 to 2020, while mangrove cover had increased by 14.1 km2 from 2005 to 2020 (15 years). The overall reduction in the area between the west and east banks of the Creek was around 15.3 km2 from 1972 to 2020. This study shows that Thane Creek is rapidly narrowing at its northern end

Abstract: The World Vegetable Center, Taiwan regards traditional vegetables as one of the important means of ‘climateresilient pathways’. Momordica sahyadrica is a lesserknown traditional vegetable having neutraceutical virtues. It grows well under marginal input and partial shade environment, thereby, it aptly highlights one of its niche attributes, ‘climate resilience’. It is endemic to the typical habitat of the Western Ghats (Sahyadri mountain range) and is a distinguished species of the well-known vegetable genus Momordica. Popularizing this species, conservation through cultivation, and further focused research and development using various techniques will facilitate the recovery of promising genotypes and mainstreaming of this Sahyadri gourd.

Subject: Financial burden of psychiatric disorders of Telangana state, India
Keywords: Case study, cost estimation, financial burden, health budget, psychiatric disorders.
Abstract: Psychiatric disorders can be devastating, causing damage to the patient, his/her family and society. Financial aspect is the main criterion in a disease or group of diseases for decision-making, planning and prioritizing issues. The aim of the present study was to estimate the tangible cost of psychiatric disorders per annum in Telangana, India, from societal perspective. Cost estimation of various components was done under direct and indirect heads. The direct costs included were consultation, drugs, inpatients, investigations, procedures, psychologist consultation, rehabilitation and travel for treatment. The indirect costs included attendant, disability benefits, faith healing, loss of taxes on earnings, patients in conflict with the law, student training, statutory bodies, substance abuse, suicide and attempted suicide, work absence/loss of wages and productivity. Costs were also estimated based on other published works and local conditions. Of the Rs 140,963.0 crore cost, direct costs were only a small fraction (2%) while fraction indirect costs were high (98%). Cost due to wages and productivity loss accounted for 55% of the total cost. The estimated arrived at was several times more than the total health budget of the state. Thus, there is an urgent need to improve and expand mental health services to reduce the financial burden

Keywords: Cannibalistic nature, competitive displacement, fall armyworm, habitat occupancy, larval density, stem borer.
Abstract: Invasion of fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae) has been implicated in reducing the incidence of native stem borers in India. The present study aimed to verify the reasons for the displacement of native stem borers using S. frugiperda and pink stem borer, Sesamia inferens (Walker) (Lepidoptera: Noctuidae). Field incidence of FAW and S. inferens was recorded during the 2020 and 2021 wet seasons, indicating negligible field incidence of S. inferens compared to FAW. In controlled greenhouse experiments, the competition was measured by releasing larvae at different densities into the maize whorl and also by varying their release at two-day intervals among the two species tested. In competition assays, the frequency of cannibalism increased with increasing density. The study documents that cannibalistic nature and early habitat occupancy in the whorls by FAW are the key factors involved in reducing the incidence of native stem borer, S. inferens

Subject: Geoelectrical study for groundwater resources in parts of the Ahmedabad and Gandhinagar cities, Gujarat, India
Keywords: Aquifers, borehole data, groundwater, sedimentary basins, two-dimensional resistivity imaging
Abstract: The central alluvial plains of Gujarat, western India, consist of deposits of north–south flowing rivers from the Aravalli hills. The Gandhinagar and Ahmedabad districts in the state form a part of the Cambay basin and are occupied by Quaternary alluvium comprising mainly of sand, gravel, silt clay, kankar, etc. Direct current (DC) electrical resistivity studies have been carried out at six sites in Gandhinagar and Ahmedabad cities to map groundwater levels and major shallow subsurface geoelectric layers using a 72-electrode resistivity imaging system. Two dimensional (2D) resistivity models and borehole data infer a multilayered aquifer system in Ahmedabad. The top confined aquifer is at a depth of 22–25 m and the second unconfined aquifer is at a 60–65 m depth. These two aquifers are separated by highly compacted clay/clayey sand. For the two locations in Ahmedabad city, the 2D resistivity model suggests 10–15 m variation in the groundwater level. In Gandhinagar, as the survey location is close to the Sabarmati River and the exploitation of groundwater is less than in Ahmedabad, the groundwater table is at shallow level. Further, the resistivity estimates suggest that, at all three locations, the groundwater is moderately saline. The infer resistivity sections are correlated with groundwater level and borehole data.

Subject: Iron technology in medieval Kerala: archaeometallurgical studies on iron artefacts from Triprangode
Keywords: Archaeometallurgical studies, AMS dating, iron artefacts, medieval period, microstructure
Abstract: Iron was a new entrant and a must in weaponry in the 2nd and 1st millennium BCE. There is every possibility of iron being used for generations, and deposited or hidden it for use in the times of need or even as a part of religious activities. Dating iron has been mostly based on the associated finds, and iron has been repeatedly melted, shaped and reused. Differentiating the iron in use at present from that in earlier times has been a challenge, and requires the dating of artefacts. Chemical objects characterization is contextual-specific. Three iron objects recovered from a cave near Triprangode, Kerala, India was studied using various analytical techniques to understand the metallurgical characteristics such as microstructure, phases, inclusions and production technology. The artefact was also dated using accelerator mass spectroscopy (AMS). The three artefacts included two swords and a tripod, which were reported to belong to the 1st millennium BCE based on associated pottery finds and typological comparison. Optical microscopy and scanning electron microscopy techniques were employed for microstructure analysis. X-ray fluorescence analysis was used to identify the elements present in the samples. X-ray diffraction and energy dispersive X-ray spectroscopy analyses were performed to identify the phases present in the samples. AMS radiocarbon dating was carried out to determine the age of the artefacts. A combination of these techniques helped identify the iron-making process.

Subject: DNA barcoding of rotifers along the Cochin backwaters, southwest coast of India
Keywords: Backwaters, DNA barcoding, partial sequences, pure culture, rotifer
Abstract: This study examines the DNA barcoding of rotifers from the Cochin backwaters, Kerala, India, with specimens obtained from the pure culture, using primers LCO1490/ HCO2198 and a recently reported primer 30F/885R which was designed especially for the rotifers. Partial sequences of the mitochondrial COI gene from five species belonging to three genera (Brachionus, Keratella and Asplanchna) and two families (Brachionidae and Asplanchnidae) of the order Ploimida were generated. All the obtained nucleotide sequences were submitted to NCBI (accession numbers: OL477582–OL477584, OL477586 and OL757796)

Subject: An optimal vaccination strategy for pandemic management and its impact on economic recovery
Keywords: Economic recovery, mobility, nonlinear regression, pandemic management, reproduction number, vaccination strategy.
Abstract: The economic impact of the COVID-19 pandemic has been devastating for countries across the world. We propose a novel method for estimating reproduction number (R0) using community mobility to obtain optimal vaccination coverage (OVC). Different scenarios for achieving the desired immunization rates are evaluated using nonlinear regression models. The impact of recovery rates on mobility is also assessed to determine how the economy would have fared in various scenarios. Lockdowns due to COVID-19, which restricted mobility, were the main cause of the decline in GDP. For the city of Mumbai in India, with an increase in recovery rate from 1% to 5%, it was observed that mobility and thus economic activity might have been restored to some extent. The findings presented here may aid the governing bodies in developing more effective emergency response plans.

Subject: Impact of lifestyle intervention among prediabetic individuals
Keywords: Blood glucose, diet, exercise, lifestyle, prediabetes.
Abstract: Prediabetes is a stage before diabetes that refers to impaired fasting glucose or impaired glucose tolerance, or a combination of both. Sedentary work and unhealthy food patterns lead to prediabetes, and lifestyle modification is important. Hence the present study focuses on the impact of lifestyle intervention among prediabetic persons. One hundred and twenty-five people, excluding patients diagnosed with diabetes, from the Arthur Asirvatham Hospital in Madurai, Tamil Nadu, India were selected for the study. Demographic details were collected and anthropometric measurements like height, weight, body mass index and waist–hip ratio were made. The blood samples were analysed for fasting blood sugar, postprandial blood sugar, glycosylated haemoglobin, lipid profile and urine samples for urine microalbuminuria. Blood pressure was also measured. The participants were given a strict diet and exercise chart, after which they were followed up for six months. The collected data were analysed using appropriate statistical methods. Of the 125 prediabetes subjects enrolled, the mean age was 41.65 ± 7.56 years, with 71.2% male and 28.8% female. The mean height of the patients throughout the study was 159 ± 10.04 (cm). Overall there was a statistically significant reduction in weight (65.3 ± 13.24–64.4 ± 12.86 kg), body mass index (25.8 ± 4.42 to 25.5 ± 4.29 kg/m2 ), fasting (111 ± 10.42 to 107 ± 8.5 mg/dl), postprandial blood sugar (159 ± 19.35 to 152 ± 18.8 mg/gl) and glycosylated haemoglobin (5.8 ± 0.18% to 5.7 ± 0.2%) between baseline and various follow-up visits (P < 0.05). Lifestyle intervention had a greater impact on lipid profile and no change in urine microalbuminuria in baseline and final visits. The study concludes that lifestyle intervention significantly impacts prediabetic subjects to avoid type-2 diabetes and its complications.
