Molecular Identification of Genetically Modified Crops for Biosafety and Legitimacy of Transgenes

Crops undergo artificially DNA modifications for improvements are considered as genetically modified (GM) crops. These modifications could be in indigenous DNA or by introduction of foreign DNA as transgenes. There are 29 different crops and fruit trees in 42 countries, which have been successfully modified for various traits like herbicide tolerance, insect/pest resistance, disease resistance and quality improvement. GM crops are grown worldwide and its area is significantly increasing every year. Many countries have very strict rules and regulations for GM crops and are also a trade barrier in some situations. Hence, identification and testing of crops for GM contents is important for identity and legitimacy of transgene to simplify the international trade. Normally, molecular identification is performed at three different levels, i.e., DNA, RNA and protein, and each level has its own importance in testing about the nature and type of GM crops. In this chapter, current scenario of GM crops and different molecular testing tools are described in brief

DNA Fingerprinting and Cultivar Identification of Olive (Olea europaea L.) using SSR markers

Background: Genetic diversity and population structure of the olive varieties cultivated in Pakistan are yet to be explored.Methods: In present study, we studied population structure and genetic diversity and developed DNA fingerprints of 13 olive varieties  using 63 Simple Sequence Repeat  markers.Results: Collectively 618 alleles were amplified among which 582 were polymorphic and 36 were monomorphic. High allelic diversity per locus was found among 63 SSR markers, i.e., one for GAPU-12 to 23 for UDO099-008 and GAPU-47 with an average 9.80 alleles per locus. On the basis of cluster analysis genotypes were grouped into two clusters. Cluster I contained varieties Manzanilla, Sohawa-selection, Koroneki, Bulkasar-selection, Arbequina, Arbosona, Chugtai-selection, whereas cluster II was comprised of varieties Bari-Zatoon, Coratina, Gemlik, Frontaio, Pendolino and Ottobratica. UDO-24 marker alone identified seven olive varieties. Similarly, DCA-07 and EMO-02 identified six olive varieties each.Conclusion: The findings of this manuscript will be helpful for future studies related to DNA fingerprinting and genetic diversity assessment for choice of SSR markers and identification of olive varieties.   Keywords: Cluster analysis; Polymorphic Information Content; Structure analysis; Similarity matrix

Omega-3 and omega-6 polyunsaturated fatty acids and their potential therapeutic role in protozoan infections

Protozoa exert a serious global threat of growing concern to human, and animal, and there is a need for the advancement of novel therapeutic strategies to effectively treat or mitigate the impact of associated diseases. Omega polyunsaturated fatty acids (ω-PUFAs), including Omega-3 (ω-3) and omega-6 (ω-6), are constituents derived from various natural sources, have gained significant attention for their therapeutic role in parasitic infections and a variety of essential structural and regulatory functions in animals and humans. Both ω-3 and ω-6 decrease the growth and survival rate of parasites through metabolized anti-inflammatory mediators, such as lipoxins, resolvins, and protectins, and have both in vivo and in vitro protective effects against various protozoan infections. The ω-PUFAs have been shown to modulate the host immune response by a commonly known mechanism such as (inhibition of arachidonic acid (AA) metabolic process, production of anti-inflammatory mediators, modification of intracellular lipids, and activation of the nuclear receptor), and promotion of a shift towards a more effective immune defense against parasitic invaders by regulation the inflammation like prostaglandins, leukotrienes, thromboxane, are involved in controlling the inflammatory reaction. The immune modulation may involve reducing inflammation, enhancing phagocytosis, and suppressing parasitic virulence factors. The unique properties of ω-PUFAs could prevent protozoan infections, representing an important area of study. This review explores the clinical impact of ω-PUFAs against some protozoan infections, elucidating possible mechanisms of action and supportive therapy for preventing various parasitic infections in humans and animals, such as toxoplasmosis, malaria, coccidiosis, and chagas disease. ω-PUFAs show promise as a therapeutic approach for parasitic infections due to their direct anti-parasitic effects and their ability to modulate the host immune response. Additionally, we discuss current treatment options and suggest perspectives for future studies. This could potentially provide an alternative or supplementary treatment option for these complex global health problems

Discovering the Correlation Between Phishing Susceptibility Causing Data Biases and Big Five Personality Traits Using C-GAN

Recently, on social media, various kinds of social engineering (SE) have made individuals more susceptible to attacks. A phishing attempt is a widely used SE technique that takes advantage of people’s vulnerabilities to acquire personal or confidential information. These attempts are growing at an astonishing speed, causing harm to both individuals and corporations. According to the latest studies, certain individuals are more vulnerable to such kinds of attacks than others. However, the relationship between psychological characteristics and phishing attacks has not been adequately investigated. This study empirically explores the connection between phishing vulnerability that causes data biases and the Big Five personality traits. Recognizing personality traits that make people more vulnerable to phishing attempts is a key step in developing protection and safeguarding individuals. The individuals who scored high in some traits are more probable to suffer from such assault. To the best of our knowledge, no prior quantitative study has attempted to find many genuine phishing victims and their personality behavior. This problem lacks the availability of publically accessible data. It is also challenging to estimate the probability distribution of rows in tabular data and generate realistic synthetic data to train/test the model on more data. This work employs a conditional generative adversarial network (C-GAN) for both data generation and classification to find the correlation between personality traits and phishing attacks

Background: Root canal treatment is an endodontic procedure that encompasses cleaning & shaping i.e. preparation of root canals followed by obturation of the prepared canals. Pain is a very common sensation that occurs few hours after root canal treatment (RCT). Objective: To evaluate and compare the efficacy of premedication with flurbiprofen and prednisolone on post-endodontic pain in teeth with symptomatic irreversible pulpitis. Materials and Methods: It is a randomized control trial study conducted in the department of Operative Dentistry & Endodontics, Sardar Begum Dental College, & Hospital Peshawar. Patients were randomly allocated into two groups i.e. A and B using coin flip technique. Thirty minutes before starting the endodontic therapy, single pretreatment dose of Flurbiprofen (100mg) was given to patients in Group A and Prednisolone (30mg) to patients in Group B. Patients’ pain intensity experience was measured using the visual analog scale (VAS) after root canal treatment. They were instructed to complete a pain diary at specific intervals (i.e. at 6, 12 and 24 hours after the commencement of treatment) in order to determine efficacy in both groups. Results: As per efficacy in both groups, in Group A, 44 (55%) showed effective results whereas in Group B, only 20 (25%) patients showed effective results. Conclusion: Single pretreatment dose of flurbiprofen has a more sustained effect in reducing post-endodontic pain as compared to prednisolone

Aging Mechanisms: Linking oxidative stress, obesity and inflammation

Aging cannot be defeated in anyway in the world even having new and advanced technology. But molecular mechanism is a successful method to control aging. Many complex and multifunctional factors are the main cause of aging. It is evident that the studies regarding cellular, genetic, and pathological and biochemical changes are exploring more and more pathways linking various diverse mechanism explaining aging. Implications of basic mechanisms of aging for improving both longevity and quality of life in human needs a clear understanding and takes a long time. However, reactive oxygen species (ROS) indicate a growing body even in the presence of fundamental mechanisms. According to oxidative stress theory, advanced and permanent addition of oxidative damage on critical aspects of aging process instigated by ROS influences. Telomeres theory is another, new aging theory that holds many promising possibilities for the field of anti-aging medicine. The theory was originated from the surge of technological breakthroughs in genetics and genetic engineering. Telomeres have also been found related to obesity. Obesity also leads to accelerated cellular processes. A “causative agent in aging” is considered inflammation that underlies a mechanism showing that for survival acute inflammatory response is necessary but long term exposure to different antigens than predicted by evolution cause low-grade inflammatory status which intern contributes to age-associated illness and death. The condition known as “inflammaging”

Infectious aetiologies of neonatal illness in south Asia classified using WHO definitions: a primary analysis of the ANISA study.

BACKGROUND: Globally, neonatal mortality accounts for almost half of all deaths in children younger than 5 years. Aetiological agents of neonatal infection are difficult to identify because the clinical signs are non-specific. Using data from the Aetiology of Neonatal Infections in south Asia (ANISA) cohort, we aimed to describe the spectrum of infectious aetiologies of acute neonatal illness categorised post-hoc using the 2015 WHO case definitions of critical illness, clinical severe infection, and fast breathing only. METHODS: Eligible infants were aged 0-59 days with possible serious bacterial infection and healthy infants enrolled in the ANISA study in Bangladesh, India, and Pakistan. We applied a partial latent class Bayesian model to estimate the prevalence of 27 pathogens detectable on PCR, pathogens detected by blood culture only, and illness not attributed to any infectious aetiology. Infants with at least one clinical specimen available were included in the analysis. We assessed the prevalence of these aetiologies according to WHO's case definitions of critically ill, clinical severe infection, and infants with late onset, isolated fast breathing. For the clinical severe definition, we compared the prevalence of signs by bacterial versus viral aetiology. FINDINGS: There were 934 infants (992 episodes) in the critically ill category, 3769 (4000 episodes) in the clinical severe infection category, and 738 (771 episodes) in the late-onset isolated fast breathing category. We estimated the proportion of illness attributable to bacterial infection was 32·7% in infants in the critically ill group, 15·6% in the clinical severe infection group, and 8·8% among infants with late-onset isolated fast breathing group. An infectious aetiology was not identified in 58-82% of infants in these categories. Among 4000 episodes of clinical severe infection, those with bacterial versus viral attribution had higher proportions of hypothermia, movement only when stimulated, convulsions, and poor feeding. INTERPRETATION: Our modelled results generally support the revised WHO case definitions, although a revision of the most severe case definition could be considered. Clinical criteria do not clearly differentiate between young infants with and without infectious aetiologies. Our results highlight the need for improved point-of-care diagnostics, and further study into neonatal deaths and episodes with no identified aetiology, to ensure antibiotic stewardship and targeted interventions.
