Hepatocellular carcinoma (HCC) is one of the major causes of morbidity, mortality, and healthcare expenditure in patients with chronic liver disease in India. The Indian National Association for Study of the Liver (INASL) had published its first guidelines on diagnosis and management of HCC (The Puri Recommendations) in 2014, and these guidelines were very well received by the healthcare community involved in diagnosis and management of HCC in India and neighboring countries. However, since 2014, many new developments have taken place in the field of HCC diagnosis and management, hence INASL endeavored to update its 2014 consensus guidelines. A new Task Force on HCC was constituted that reviewed the previous guidelines as well as the recent developments in various aspects of HCC that needed to be incorporated in the new guidelines. A 2-day round table discussion was held on 5th and 6th May 2018 at Puri, Odisha, to discuss, debate, and finalize the revised consensus statements. Each statement of the guideline was graded according to the Grading of Recommendations Assessment Development and Evaluation system with minor modifications. We present here the 2019 Update of INASL Consensus on Prevention, Diagnosis, and Management of Hepatocellular Carcinoma in India: The Puri-2 Recommendations. © 2019
A Molecular and Spectroscopic Approach to Reclamation of Coal Mine Soil Using Tree Species: a Case Study of Gevra Mining Area, Korba, India
(Springer Science and Business Media Deutschland GmbH, 2022) Preeti Singh; A.K. Ghosh; Santosh Kumar; S.L. Jat; Kumari Seema; Satya Narayana Pradhan; Manoj Kumar
Loss of topsoil and mechanical mixing of soil horizons of mining land causes depletion of huge amounts of carbon (C). Biological reclamation of the soils of mining land helps in soil organic carbon (SOC) sequestration. Therefore, to quantify the quality and quantity of soil organic carbon sequestered through biological reclamation, a chronosequence study consisting of 8- and 25-year-old reclaimed mine soil substrates planted with three different plant species, viz Azadirachta indica, Gmelina arborea and Dalbergia sissoo was undertaken at Gevra, Chhattisgarh, India. Microbial biomass carbon (MBC) and mean SOC stock were recorded highest for A. indica (1468.45 mg C kg−1 soil substrate and 334.72 Mg C ha−1 respectively) after 25 years of reclamation. All the three tree species contributed significantly in raising the non-labile SOC pool among which, the contribution of A. indica (88.25%) was found highest. SOC stock (69.82 Mg C ha−1) was found highest for topsoil substrate of 25-year-old re-vegetated site. This increase in SOC in topsoil substrate associated with a higher carbon input and the lower rates of SOC decomposition following revegetation indicated accumulation of more stable SOC forms with time. The nitrogen (N) content (r = − 0.51, p < 0.01) and C/N ratio (r = 0.56, p < 0.05) in the litter were an important controlling factor for TSOC. SOC molecules became more aromatic with a higher degree of substitution by reactive functional groups in the 25-year-old restored minesoil substrates as observed from spectroscopic analysis (E4/E6 and A253nm/A220nm). After 25 years of reclamation, similar Fourier transform infrared (FT-IR) absorption bands were observed for all tree species. However, the intensities at 1618- 1651 cm−1 in humic acid (HA) of G. arborea were higher, indicating presence of aromatic C=C, ascribed to the higher complexity of the HA fraction for G. arborea. The results indicated that spectroscopic methods (FT-IR, UV–vis, E4/E6 ratio) were clearly able to distinguish between restored minesoil substrates on the basis of the characteristics of SOC molecules and can be useful to shedding light on SOC dynamics and sequestration processes. © 2022, The Author(s) under exclusive licence to Sociedad Chilena de la Ciencia del Suelo.
A review of toxicological profile of cadmium (CD)
(2010) Prashant Agrawal; Anugya Mitral; Manoj Kumar; S.K. Tripathi
The distribution of toxic heavy metals in the environment is a major concern in many industrialized countries purview of the human health. The main sources of cadmium in the air are the burning of fossil fuels such as coal or oil and the incineration of municipal waste. The acute (short-term) effects of cadmium in humans through inhalation exposure consist mainly of effects on the lung, such as pulmonary irritation. Chronic (long-term) inhalation or oral exposure to cadmium leads to a buildup of cadmium in the kidneys that can cause kidney disease. Cadmium has been shown to be a developmental toxicant in animals, resulting in fetal malformations and other effects, but no conclusive evidence exists in humans. Animal studies have demonstrated an increase in lung cancer from long-term inhalation exposure to cadmium.
A review on instant controlled pressure drop technology – a strategic tool for extraction of bioactive compounds
(John Wiley and Sons Inc, 2022) Nisha Chaudhary; Priya Dangi; Vandana Chaudhary; Aastha Dewan; Sujata Pandit Sharma; Amrita Poonia; Manoj Kumar
Bioactive compounds are the naturally derived extra-nutritional components with diversified arrangement and functionality, which makes them a promising source for the fabrication of functional foods, nutraceuticals and food additives. Extraction of these compounds by traditional techniques is a cumbersome process, which yields product with compromised quality and poor efficiency besides huge investment in terms of energy and time. This urges an acute need to develop an improved method that ensures the nutritional and organoleptic quality of these bioactive components is better preserved. Instant controlled pressure drop is one such novel and sustainable technique that allows the raw materials to be treated at high pressure and temperature first and latterly followed by an abrupt pressure drop towards a vacuum. The induced thermo-mechanical effects in the sample ensure boost in availability and extractability of high-value bioactive compounds. This technique has found numerous applications in food industry such as a pre-treatment in drying and freezing of food product, enhanced extraction of bioactive compounds and to improve the colour, odour and texture quality of a variety of food products. This review article will emphasise on all these aspects of instant controlled pressure drop technology. © 2022 Institute of Food Science and Technology.

(Medico-Legal Update, 2008) Senti Toshi; S.K. Pandey; Manoj Kumar; S.K. Tripathi
The present paper is a highlight of the hazards and risks, present in the autopsy centre and faced by the workers involved in the autopsy room. This study was conducted in the department of FORENSIC MEDICINE, IMS, BHU, Varanasi, during the year 2007. It was found that about one-fourth i.e. 502 cases (25.48%) of the total 1970 autopsy cases done were hazardous. Of which, infective risk contributed the highest (67.52%) and then followed by poisoning cases (32.47%). There were also 43 cases of decomposed bodies autopsied. The other existing hazards were studied through a questionnaire put forward to the workers regarding physical injury, exposure to chemical hazards, infections and adverse psychological effects, secondary to stressful working environment of the autopsy room and presence of other occupational hazards if any.

(2011) Manoj Kumar; Madhumita Mukherjee; K.K. Gupta; Pallavi Pathak
Blood transfusion practices in a tertiary care hospital and teaching institute i.e SSL hospital, BHU, Varanasi were analysed through retrospective study of blood bank records for the year 2008-09. It was found that voluntary blood donation was 20.41% and 58.65% in the year 2008 and 2009 whereas replacement blood donations were 79.59% in the year 2008 and 41.35% in the year 2009. Male voluntary blood donors in the year 2008 and 2009 were 92.33% and 90.26% whereas male replacement donors in the year 2008 and 2009 were 91.09% and 89.55% respectively. Most common blood donor age group in the year 2008 -09 were from 21-35 years contributing 52.45% and 51.07% in respective years. Only 70.20% and 55.48% whole blood of the total blood units was utilized during this period and rest in the form of blood components. The prevalence of HIV seropositivity was nil. Hence it is inferred that more than 99% of the total blood collected in this blood bank is safe to use.
Absorbing aerosols, possible implication to crop yield - a comparison between IGB stations
(AAGR Aerosol and Air Quality Research, 2017) R. Latha; B.S. Murthy; K. Lipi; Manoj K. Srivastava; Manoj Kumar
The current study compares black carbon radiative effects at the densely populated plain station, Varanasi and the lesser populated plateau station Ranchi with large forest cover but with numerous open coal mines. While the measured average black carbon mass density (BC) reduces from February to March at Ranchi following an increase in convective mixing, it is observed to increase by 150% from February to March in Varanasi, as transport from northeast forest fires increases. It is observed that absorption due to black carbon of non-fossil fuel origin is prevalent throughout the day, in Varanasi, while this contribution is most significant during post sunset hours in Ranchi. Radiative forcing, estimated hourly using chemical model (to derive BC-aod) and radiative transfer model, indicates that at least 5% of the incoming radiation is always cutoff during any time of the day in Varanasi while this is about 4% in Ranchi. BC effectively causes an apparent delayed sunrise by reducing the incoming radiation on the plains of Indo Gangetic Basin (IGB) by up to 25% at the daybreak. An estimate of crop loss due to cut off in radiation, using an empirical formula for crop yield as a function of radiation, indicates a possible loss of more than a quintal per hectare considering anthesis (February) and maturity (March) periods for the winter wheat in both the IGB stations with consistently higher losses in Varanasi. © Taiwan Association for Aerosol Research.

(MDPI, 2022) Pradeep Kumar; Akansha Gupta; Dipendra Kumar Mahato; Shikha Pandhi; Arun Kumar Pandey; Raveena Kargwal; Sadhna Mishra; Rajat Suhag; Nitya Sharma; Vivek Saurabh; Veena Paul; Manoj Kumar; Raman Selvakumar; Shirani Gamlath; Madhu Kamle; Hesham Ali El Enshasy; Jawahir A. Mokhtar; Steve Harakeh
Cereals and cereal-based products are primary sources of nutrition across the world. However, contamination of these foods with aflatoxins (AFs), secondary metabolites produced by several fungal species, has raised serious concerns. AF generation in innate substrates is influenced by several parameters, including the substrate type, fungus species, moisture content, minerals, humidity, temperature, and physical injury to the kernels. Consumption of AF-contaminated cereals and cereal-based products can lead to both acute and chronic health issues related to physical and mental maturity, reproduction, and the nervous system. Therefore, the precise detection methods, detoxification, and management strategies of AFs in cereal and cereal-based products are crucial for food safety as well as consumer health. Hence, this review provides a brief overview of the occurrence, chemical characteristics, biosynthetic processes, health hazards, and detection techniques of AFs, along with a focus on detoxification and management strategies that could be implemented for food safety and security. © 2022 by the authors.
Agroecosystem contamination with heavy metals due to road transportation: A global threat to safe food security
(Institution of Chemical Engineers, 2025) Akshay Kumar Singh; Jatin Kumar Choudhary; Sushil Kumar Shukla; Kuldeep Bauddh; Gavendra C. Pandey; Sughosh Madhav; Ajai Singh; Manoj Kumar
Road transportation significantly contributes to heavy metals (HMs) in the atmosphere. The introduction of HMs into the environment is a major global ecotoxicological concern. The proliferation of road networks, coupled with the escalating vehicular volume, has exacerbated the presence of HMs, including lead (Pb), cadmium (Cd), manganese (Mn), mercury (Hg), copper (Cu), chromium (Cr), in agricultural soil and crops proximate to transportation arteries, thereby imperilling global food security. The current review focused on the significant contamination of HMs in agroecosystems worldwide due to road transportation. It highlights the various pathways through which HMs are transported to agroecosystems and their impact on nearby ecosystems. The review also evaluates the degree of HMs contamination and its subsequent transfer into soil and crops such as geoaccumulation index (Igeo), enrichment factor (EF), translocation factor (TF), and bioaccumulation factor (BAF). Recent studies have shown that harmful HMs can be absorbed by edible parts of crops, which are then consumed directly by humans. A study conducted near the National Highway in Jhansi, India found high levels of HMs in the edible parts of tomato plants (Cu – 4.77 mg/kg, Cd- 0.14 mg/kg, nickel (Ni) – 0.89 mg/kg, and Mn – 14.46). Similar studies conducted in various parts of the world have also observed increased HMs in agricultural soil and crops near roads. The current review aims to investigate HMs contamination in agroecosystems caused by road transportation and to suggest directions for future research to reduce HMs emissions from the sources. © 2024 The Institution of Chemical Engineers
An Improved Reversible Data Hiding Technique For Encrypted Images Using Difference Error Expansion
(Springer Science and Business Media Deutschland GmbH, 2022) Ankita Vaish; Ruchi Agarwal; Manoj Kumar
Digital data hiding exists in many forms, one of its most useful form is reversible data hiding which recovers the secret data and extracts the cover image exactly as these were at the time of embedding. In last few years, encryption and reversible data hiding have been combined to explore a new area of research, seeking researchers’ interest in very short span of time. To enhance the payload, this paper presents a novel reversible data hiding technique for encrypted images using bilinear interpolation and difference error expansion. Difference error expansion is a technique used to embed watermark in the images, by exploiting the spatial redundancy which exists in digital images. In difference expansion schemes, correlation of adjacent pixels is exploited to create the space for embedding of secret data. This paper aims to elevate the embedding capacity and reduce the distortion effect caused by embedding with the help of difference error expansion-based reversible data hiding method. The proposed scheme investigates the use of bilinear interpolation by utilizing the pixels located at even rows and even columns for the prediction of neighbouring pixels. Notably, good results are obtained when proposed work is compared with the existing ones on the basis of embedding capacity and PSNR. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

(Taylor and Francis Ltd., 2023) Somesh Kumar; Neha Choudhary; Mohammed Faruq; Arun Kumar; Ravindra K. Saran; Prem Kumar Indercanti; Vikram Singh; Haseena Sait; Sunita Jaitley; Martin Valis; Kamil Kuca; Sunil K. Polipalli; Manoj Kumar; Tejveer Singh; Prashanth Suravajhala; Rohit Sharma; Seema Kapoor
The mitochondrial permeability transition pore (mtPTP) plays a vital role in altering the structure and function of mitochondria. Cyclophilin D (CypD) is a mitochondrial protein that regulates mtPTP function and a known drug target for therapeutic studies involving mitochondria. While the effect of aromatase inhibition on the mtPTP has been studied previously, the effect of anastrozole on the mtPTP has not been completely elucidated. The role of anastrozole in modulating the mtPTP was evaluated by docking, molecular dynamics and network-guided studies using human CypD data. The peripheral blood mononuclear cells (PBMCs) of patients with mitochondrial disorders and healthy controls were treated with anastrozole and evaluated for mitochondrial permeability transition pore (mtPTP) function and apoptosis using a flow cytometer. Spectrophotometry was employed for estimating total ATP levels. The anastrozole–CypD complex is more stable than cyclosporin A (CsA)–CypD. Anastrozole performed better than cyclosporine in inhibiting mtPTP. Additional effects included inducing mitochondrial membrane depolarization and a reduction in mitochondrial swelling and superoxide generation, intrinsic caspase-3 activity and cellular apoptosis, along with an increase in ATP levels. Anastrozole may serve as a potential therapeutic agent for mitochondrial disorders and ameliorate the clinical phenotype by regulating the activity of mtPTP. However, further studies are required to substantiate our preliminary findings. Communicated by Ramaswamy H. Sarma. © 2023 Informa UK Limited, trading as Taylor & Francis Group.
