Analysis of Abstractive and Extractive Summarization Methods

This paper explains the existing approaches employed for (automatic) text summarization. The summarizing method is part of the natural language processing (NLP) field and is applied to the source document to produce a compact version that preserves its aggregate meaning and key concepts. On a broader scale, approaches for text-based summarization are categorized into two groups: abstractive and extractive. In abstractive summarization, the main contents of the input text are paraphrased, possibly using vocabulary that is not present in the source document, while in extractive summarization, the output summary is a subset of the input text and is generated by using the sentence ranking technique. In this paper, the main ideas behind the existing methods used for abstractive and extractive summarization are discussed broadly. A comparative study of these methods is also highlighted

Menstruation hygiene and related issues in adolescent girls: A brief commentary

Between childhood and adulthood, adolescence is a phase of physiological, psychological, and social transformation. Menstrual difficulties are a common symptom and one of the primary causes of adolescent doctor visits. Therefore, adolescent girls' knowledge of reproductive health, including menstruation, may be incomplete and impacted by sociocultural obstacles. The majority of teenage females in India know nothing about menstruation, reproduction, and sexuality. As menstruation remains a taboo, the culture adheres to numerous myths and prohibitions. During menstruation, poor personal cleanliness and dangerous sanitary circumstances heighten the risk of reproductive tract infections and gynecological issues. In resource-poor environments, where women lack access to basic facilities such as water, bathrooms, and privacy, it is extremely difficult to maintain a high level of hygiene. There is a need to enhance housing conditions in terms of fundamental amenities. Every girl may only be encouraged to use sanitary pads if they are offered at cheap costs. It is urgent that separate teenage gynecological clinics be established. Sensitization and counseling in schools, together with a complete school education program on menarche and menstruation difficulties, may assist girls in coping better and seeking appropriate medical support.

Morphometeric study of dens and its clinical importance

Background: The axis vertebra's distinguishing characteristic is the existence of the odontoid process. The axis vertebra's morphology is very different from the morphologies of the other cervical vertebrae. Surgery on the axis vertebrae is exceedingly risky, and dens of axis vertebrae fractures are fairly common. As a result, it is essential to have a good grasp of the anatomical variance before performing the procedure. The study aimed to evaluate the morphometric parameters of the odontoid process of the axis vertebra. The different anatomical parameters of the odontoid process of the vertebra will be measured and compared with the previously studied parameters. Methods: Thirty dried human axis vertebrae of unknown sex will be taken. The linear and angular morphometric measurements of odontoid process will be recorded by using vernier caliper and goniometer. Results: The mean height, a-p diameter, and minimum and maximum width were 15.8mm, 10.7mm, 10.3mm and 8.5mm respectively. The total height and vertical angle were 38.1mm and 52.2 degrees respectively. Conclusions: To prevent damage to vital components and to help treat dens fractures, the information gleaned from this study may be helpful to surgeons working around the dens of the axis vertebra

Synthesis of some novel 1,2,4-triazole derivatives as potential antimicrobial agents

An efficient synthesis of 1,2,4-triazole derivatives, fused to five and six membered rings from 4-amino-5-[(quinolin-8-yloxy)methyl]-4H-1,2,4-triazole-3-thiole (2) was described. The structural formula of all derivatives was confirmed and characterized by elemental analysis and spectral studies. Some of the synthesized compounds were also investigated for their antibacterial and antifungal activities and compared with standard drugs. Most of the tested compounds demonstrated potent to weak antimicrobial activities

Polycystic Ovary Syndrome, a modern epidemic: An overview

Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder affecting women, but can be very difficult to diagnose and treat due to vague presentation of symptoms and a lack of standardization in treatment. PCOS is characterized by hyperandrogenic manifestation like acne, hirsutism and chronic anovulation and is associated with metabolic derangement such as hyperlipidemia, hyperinsulinemia, insulin resistance and Type 2 diabetes mellitus.The cause of polycystic ovary syndrome is still unclear due to its multifactorial complexity; however, it has been observed and understood that there are several environmental and genetic factors, such as genetic variations like mutations and polymorphisms, differential regulation of genes, and pathways, may contribute to the pathogenesis of PCOS.The occurrence of considerable heterogeneity in clinical symptoms and endocrine features associated with PCOS implies that some women with Polycystic Ovaries on ultrasound scan may even exhibit none of the other features of PCOS.There is a spectacular increase in the prevalence of PCOS all over the world especially in Asia. The condition seems to be on a rise in Kashmir valley although systematic studies on the subject are still underway. In this review article, we will briefly provide an overview about the polycystic ovary syndrome. Keywords: Polycystic ovary syndrome, Genetic basis, clinical presentatio

Integrative approach for validation of six important fish species inhabiting River Poonch of north-west Himalayan region (India)

Traditionally, species of fish are identified based on morphological characteristics. Although these taxonomic descriptions are essential, there are cases where the morphological characters distinguishing these species show marginal differences. For instance, in the Poonch River in the Himalayas, there are 21 species, out of which some are morphologically similar, and the taxonomic distinction between these species is unclear. Therefore, in this study, we used sequences from two mitochondrial genes, Cytochrome b (Cyt b) and a larger ribosomal subunit (16S rRNA), as well as the morphological analysis to address any taxonomic ambiguities among the six fish species. Maximum Likelihood results revealed that all the species were clustered according to their families and genera. The phenotypic analysis also supported this statement, as all the species of different genera like Schizothorax, Tor, Garra, Traqilabeo, and Glyptothorax are grouped in their particular cluster, it shows that species of a separate class share a mutual morphological characteristic. While genetic analyses of these species suggest nucleotide diversity (p) and haplotype diversity, with Hd values as 0.644 for Cyt b and 0.899 for 16S rRNA, confirming the rich genetic diversity in the river. Overall, we recommend that the integrative approach in delimiting the fish species is more effective than the individual one and can be used to rapidly diagnose a species and understand the evolutionary relationship between the species

Assessment of biotransfer and bioaccumulation of cadmium, lead and zinc from fly ash amended soil in mustard-aphid-beetle food chain.

The present study investigates the extent of biotransfer and bioaccumulation of cadmium (Cd), lead (Pb) and zinc (Zn) from fly ash amended soil in mustard (Brassica juncea)-aphid (Lipaphis erysimi)-beetle (Coccinella septempunctata) food chain and its subsequent implications for the beetle. The soil was amended with fly ash at the rates of 0, 5, 10, 20 and 40% (w/w). Our results showed that the uptake of Cd, Pb and Zn from soil to mustard root increased with the increase in fly ash application rates, but their root to shoot translocation was relatively restricted. Increase in chlorophyll content and dry mass of mustard plant on treatments ≥20% even at elevated accumulation of Cd (1.67mgkg(-1)), Pb (18.25mgkg(-1)) and Zn (74.45mgkg(-1) dry weight) in its shoot showed relatively higher tolerance of selected mustard cultivar to heavy metal stress. The transfer coefficient (TC(1)) of Cd from mustard shoot to aphid was always >1, indicating that Cd biomagnified in aphids at second trophic level. But, there was no biomagnification of Cd in adult beetles at third trophic level. Zinc accumulation was 2.06 to 2.40 times more in aphids than their corresponding host shoots and 1.26-1.35 times more in adult beetles than their prey (aphids) on which they fed. Lead was only metal whose TC was 0.05) biomass and predation rate of predatory beetles indicated that all levels of soil amendments with fly ash did not have any lethal or sub-lethal effects on beetles

The transfer and fate of Pb from sewage sludge amended soil in a multi-trophic food chain: a comparison with the labile elements Cd and Zn

The contamination of agroecosystems due to the presence of trace elements in commonly used agricultural materials is a serious issue. The most contaminated material is usually sewage sludge, and the sustainable use of this material within agriculture is a major concern. This study addresses a key issue in this respect, the fate of trace metals applied to soil in food chains. The work particularly addresses the transfer of Pb, which is an understudied element in this respect, and compares the transfer of Pb with two of the most labile metals, Cd and Zn. The transfer of these elements was determined from sludge-amended soils in a food chain consisting of Indian mustard (Brassica juncea), the mustard aphid (Lipaphis erysimi) and a predatory beetle (Coccinella septempunctata). The soil was amended with sludge at rates of 0, 5, 10 and 20 % (w/w). Results showed that Cd was readily transferred through the food chain until the predator trophic level. Zn was the most readily transferred element in the lower trophic levels, but transfer to aphids was effectively restricted by the plant regulating shoot concentration. Pb had the lowest level of transfer from soil to shoot and exhibited particular retention in the roots. Nevertheless, Pb concentrations were significantly increased by sludge amendment in aphids, and Pb was increasingly transferred to ladybirds as levels increased. The potential for Pb to cause secondary toxicity to organisms in higher trophic levels may have therefore been underestimated
