Effect of Melatonin as Semen Additive to Tris Extender on Frozen Semen Quality of Murrah Bull Semen
The aim of the present investigation was to evaluate the impact of melatonin at different concentrations (1 mM and 2 mM) on the seminal parameters before and after cryopreservation of extended Murrah bull semen. Thirty-six ejaculates, collected with the aid of an artificial vagina twice a week from six Murrah bulls were included in the study. Each ejaculate was diluted in a Tris-citric-acid-fructose-egg-yolk-glycerol (TFYG) extender keeping 80 million sperm per ml and split into three equal aliquots, which were supplemented with melatonin (0, 1 and 2 mM; Treatment C, T1 and T2, respectively), filled in 0.25 mL straws and equilibrated for 4 hr at 4 °C, and then frozen in LN2 vapour. Frozen straws were thawed at 37°C for 30 seconds in a water bath for the post-thaw evaluation. Sperm motility, percent live sperm, sperm abnormalities, in-vitro fertility tests (hypo-osmotic swelling test & cervical mucus penetration distance) and enzyme leakage (AST, ALT) were evaluated at both post-dilution and post-thaw stages. The results revealed that the addition of melatonin, at both 1 mM and 2 mM concentrations significantly (P<0.05) improved sperm motility, sperm livability, and HOS-positive spermatozoa. Further, the sperm abnormalities and enzyme leakage were significantly (P<0.05) lower in melatonin-treated groups than in control group. The results were the best with 1 mM methionine supplementation. In conclusion, the study showed that melatonin at a concentration of 1 mM exhibited superior protection of sperm structures and functions as compared to 2 mM melatonin than the control group.
In Vitro And In Vivo Antihemolytic Effect, Acute toxicity, In Vivo Anti Inflammatory And Synergistic Antibacterial Activity of Globularia alypum Extracts
Globularia alypum (GA) is medicinal plant largely used traditionally in folk medcine in Algeria, locally named Tasselgha. It is effective in the treatement of various diseases. In present study, preparation of various extracts from Globularia alypum (GA) using solvent with increasing polarity were determined. Quantification of polyphenols and flavonoids showed that ethyl acetate extract (AcE) contains the higher amount of polyphenols. However, chloroform extract (ChE) and AcE present the higher amount of flavonoids. The antibacterial effect was evaluated using the diffusion method on agar against 11 ATCC strains. AcE and ChE were more active on the most bacteria. In synergy test with Gentamicin, additive, potential, antagonist and synergic effects were found. Acute toxicity of GA was performed on male Swiss albino mice. LD50 is up to the 400 mg/kg dose of acute treatment GA extract, we did not observe significant mortality. Anti-hemolytic activity was tested of GA extracts in vitro and in vivo respectively. All extracts increased the HT50 values (Half-Hemolysis Time) in dose-dependent manner. The concentration 84.74µg/ml of ChE and AcE enhance significantly erythrocyte antiradicalar system. Administration of methanolic crude (CrE), aqeuous (AqE) and AcE with dose of 100 mg/kg/day for 21 days resulted in a significant amelioration in both blood and plasma antioxidant capacity and was confirmed in mice treated caused a highly significant (p ≤ 0.001) delay in haemolysis HT50 = 112.8 ± 2.42 min. However, EAc and EAq (100 mg/ml) caused a non-significant delay with HT50s of 69.16 ± 8.82 min and 72.35 ± 2.49 min, respectively. CrE has a moderate activity in vitro. Nevertheless, it is the best erythrocyte antiradical in vivo with a HT50 = 112.8 min. Plasma reducing power assessed by FRAP technique was used to assess the antioxidant effect of GA extracts in vivo, reducing power (RP) continues to increase after 4 minutes of reaction and even doubles at 30 minutes for all the extracts. Reaction of ascorbic acid (VIT C) did not undergo any apparent change after the first four minutes (PR4min= 0.42 ± 0.023; PR30min= 0.55 ± 0.0174). Comparison of the reducing powers of these extracts with those of the VIT C group shows that there is no significant difference Anti-inflammatory activity using phorbol myristate acetate (PMA) on mice showed that CrE reduced the weight of the ear edema. The oedema weight of the control group was 7.26 ± 0.15 mg, reduced by Diclofenac to 4.44 ± 0.13 mg. CrE of GA (100 mg/kg) also reduced the weight to 5.88 ± 0.48. Present plant had a low degree of anti-inflammatory activity (%I= 19.00 ± 3.18%) compared with that of Diclofenac used as the reference drug (%I= 38.84 ± 1.87%). In conclusion, Globularia alypum have a strong pharmacological power, which supports their medicinal traditional use.
Relative dominance of pathogens in Alternaria leaf blight, white rust and downy mildew complex in Bundelkhand region
This study examines the prevalence and characteristics of white rust and Alternaria leaf blight in mustard crops across different locations. Variability in white rust infection rates underscores the need for further documentation on pathogen dominance. Alternaria leaf blight progresses from circular spots to extensive lesions, with A. brassicae and A. brassicicola identified as key pathogens. White rust symptoms manifest as creamy pustules, often associated with downy mildew. Microscopic analysis reveals the presence of A. candida sporangia and H. parasitica conidia, contributing to the prevalence of white rust and downy mildew mixed infection.
Suitability Classification for Construction of Rainwater Harvesting System by using Geospatial Techniques in Lumbajong and Langsomepi Watersheds of Karbi Anglong District of Assam, India
The hilly district of Karbi Anglong of Assam faces significant challenges in water supply for domestic and agricultural needs. Rainwater harvesting (RWH) emerges as a critical solution to these water crises. RWH enhances water security, particularly in areas with water scarcity, by reducing reliance on groundwater and surface water sources. Proper identification of suitable sites is essential for constructing RWH systems in watersheds. Suitability classification using geospatial techniques is crucial for this purpose. This research aims to identify and select sites for RWH systems using criteria such as land use/land cover, slope, curve number, contour, and soil type. Remote sensing (RS), geographical information system (GIS), and multi-criteria analysis were employed. GIS, especially valuable in data-scarce regions, is particularly relevant in hilly and remote areas where other data collection methods are challenging. Spatial analysis with GIS software was used to generate thematic layers and integrate them for identifying suitable RWH sites.
The effect of microwave heating on the physicochemical and microbiological quality of Raw milk
Milk and dairy products are among the most popular foods worldwide, especially for infants, and microwave usage in food preparation, particularly for milk, has become increasingly common. Therefore, the objective of this study is to assess the effect of microwaves on the physicochemical and microbiological properties of Raw milk, particularly focusing on mineral content to evaluate milk quality. The results obtained showed that the average fat, protein, lactose, and dry matter content decreased during microwave exposure, especially at 2 minutes, while acidity increased slightly. In contrast, minerals such as calcium, magnesium, and phosphorus remained stable even after 2 minutes of heating. We conclude that physicochemical and microbiological parameters are sensitive indicators of milk quality.
