Exploring FTIR Spectroscopy as promising tool for Analyzing Cancer Biomarkers: A Comprehensive Review
Fourier Transform Infrared Spectroscopy (FTIR) has emerged as a powerful tool in the analysis of biomolecular changes associated with various types of cancer. This article provides a theoretical overview of the principles of FTIR spectroscopy, its application to the analysis of cancer biomarkers, comparison between healthy and suspected individuals available in the literature, methodological considerations, clinical implications, and future directions. Here we highlight the importance of early cancer detection using FTIR spectroscopy, with emphasis on the different biomarkers that can help in the detection of different types of cancer. We focus in this study on key biomarkers such as EGFR, ALK and ROS1.
GROWTH AND VIGOUR ASSESSMENT IN SEEDLINGS OF LESSER KNOWN TREE SPECIES- Mallotus philippinensis (Lam.) Mull. Arg. OWING TO BIOFERTILIZERS
Biofertilizers were used in the present trial to assess the influence on seedling growth, vigour and survivability of Mallotus philippinensis. M. philippinensis is a lesser known tree with numerous commercial benefits. The production of quality planting materials of the tree species in short duration is a genuine problem due to seed dormancy, very slow growth rate and survivability of seedlings in the early stage. For the production of quality seedlings in a shorter period, the present investigation was carried out, which comprised of seven treatments with biofertilizers (applying @ 10 ml plant-1) viz., Control, Azotobacter, Azosprillum, Acetobacter, Pseudomonas, PSB and VAM, laid out in completely randomized design. Among the various biofertilizer treatments, maximum shoot height (21.47 cm), collar diameter (4.91 mm), number of leaves (4.23) and total leaf area per plant (150.20 cm2) were recorded in Pseudomonas, Acetobacter, Azotobacter and Azospirillum respectively. Moreover, PSB recorded at par value for shoot height with Pseudomonas, for collar diameter with Acetobacter and for number of leaves with Azotobacter. Additionally, maximum total fresh weight of plant (5.75 g) and dry weight of plant (2.29 g) were recorded in PSB. In the seedling vigour attributes, the lowest sturdiness quotient of 4.23 was observed in control treatment and the maximum root: shoot ratio of 1.88 was recorded in pseudomonas. The important vigour index, seedling quality index recorded highest of 0.46 with maximum survivability percentage of 94.70 per cent in PSB. Thus PSB @ 10 ml plant-1 treatment was the overall better performer in growth, vigour and survivability of seedlings of lesser known but commercially important tree species M. philippinensis and can be utilised for production of quality seedlings in large scale.
Study the structure of cork oak forests and macroscopic characterization of cork in thePark National of Theniet-El-Had(North-WestAlgeria).
The cork oak forest, a defining feature of the Mediterranean region, is renowned for its cork production, a commodity of substantial industrial significance. This study aims to elucidate the structure of cork oak stands in Theniet-El-Had National Park and to characterize the cork they produce. To achieve this, 40 temporary plots were established, facilitating the sampling of 390 cork oak trees across two cantons (Sidi Abdoun and Ourten). Analysis of the distribution of various dendrometric measurements reveals that these cork oak forests form stands with an irregular structure. The growth in circumference and height varies significantly with concave topography, which allows for better water accumulation, and moderately inclined terrain, which provides improved drainage. Additionally, the characterization of cork growth from the sampling units (60 calas) reveals an average increase of 2.58 mm/year. The results of the cumulative growth study show that approximately 48% of the samples reached a thickness of 27 mm after 12 years, a satisfactory period considered as the rotation for the cork oak forest of Theniet-El-Had. Furthermore, the shape of the average cork growth curve is a regressive polynomial type, indicating a regular decrease and reflecting high-quality cork. The highest growth rates are recorded during the first three years, exceeding 3 mm/year. Beyond this period, the average growth rate falls below 2 mm, reaching 1.5 mm at the end of the eleventh year of growth. This study provides foresters with restoration, regeneration methods, and cork exploitation management tools.
ASSESSING LIVESTOCK PRODUCTION DISPARITIES: A PRINCIPAL COMPONENT APPROACH
The study was undertaken to determine the factors accountable for livestock progressiveness and to identify the relative position of each district in its contribution to livestock potential in the state of Tamil Nadu by using secondary data. Factor analysis with principal component approach (PCA) was used to determine the relationship among indicators for assessing livestock production potentials. The results revealed four major components contributing to livestock production viz., “agriculture cum cow milk”, “small ruminant meat”, “buffalo milk” and “large ruminant meat”. These components together explained 64 percent of variations and their eigenvalues were greater than 1.5. The factors extracted with factor loadings above 0.4 were considered for interpretation. Based on the factor scores, eigenvalues of factors, and factor loadings, an index was constructed and the relative position of districts was identified. Further, the districts were classified into three categories based on the index: highly progressive, moderately progressive, and least progressive districts in the livestock sector. This identification of the relative position of the district based on resource availability would help the planners and policymakers to reorient their strategies on areas where livestock progress can be enhanced.
Effect of Melatonin on liquid stored semen of endangered Teressa goat under tropical humid island ecosystem of Andaman and Nicobar Islands, India
An evaluation was conducted on the effects of melatonin in semen extender on semen quality measures in Teressa bucks. For the investigation, a total of twenty-five semen samples from six bucks were chosen. Gr II, III, and IV spermatozoa were incubated in 10 µg, 20 µg, and 40 µg of melatonin/150 × 106 spermatozoa, respectively. For up to 96 hours, liquid-stored semen samples were examined for motility, viability, total sperm abnormality, plasma membrane, acrosomal and nuclear integrities, intracellular enzymes (aspartate aminotransferase; AST, alanine aminotransferase; ALT, and lactate dehydrogenase; LDH), cholesterol efflux, seminal total antioxidant capacity (TAC), and malondialdehyde (MDA) in relation to the control group (Gr I). The findings showed that, at different times during liquid storage, sperm treated with 20 µg of melatonin had significantly (P<0.05) lower total sperm abnormalities, AST, ALT, LDH, MDA, and cholesterol efflux and significantly (P<0.05) higher motility, viability, plasma membrane, acrosomal and nuclear integrities, and TAC. Antioxidants and semen quality measures were trending upward, whereas total sperm abnormalities, MDA, intracellular enzyme leakage, and cholesterol efflux were trending downward from Gr I to Gr III and subsequently in the opposite direction from Gr III to Gr IV throughout various liquid storage hours. Therefore, 20 µg of melatonin was an appropriate dosage for Teressa goat liquid semen preservation.
