Recent benthic ostracoda in the mullipallam creek, near muthupet, tamil nadu, India

Ostracods are one of the best documented groups within the whole of the animal kingdom, due to the most characteristic features of their bodies and a well calcified, tiny, bivalved carapace which fossilizes easily. They are known to inhabit a wide variety of aquatic environments such as marine, brackish, freshwater, even terrestrial, and also dwell as parasites in the intestines of fishes. The studies on Recent ostracod fauna from the seas and other marine marginal water bodies of India, especially along the east coast, are still not known fully. For the first time a study on the systematics of Recent Ostracoda from the Mullipallam creek, India. The present work on morphological studies of Recent Ostracoda from the Mullipallam creek, (Lat.l0°18'093" - 10°20710" N and Long. 078°30,840" - 79°34'876" E) has been undertaken to enhance the existing knowledge on ostracods of east coast of India. The Mullipallam creek area is located near Muthupet, belonging to Nagapattinam and Thiruvarur Districts of Tamil Nadu. The area of investigation is a marshy mangrove wetland located in the southernmost end of the Cauvery delta along the coastal zone of Bay of Bengal and Palk Straits, India. Mangrove wetlands found along the coastal zones and often dominate in estuarine and the inter-tidal zones which act as a barrier against cyclones and tsunamis protect coastal erosion and provide good nursery ground for a number of commercially important aquatic organisms. A mangrove species Avicennia marina is the dominant in the creek followed by Acanthus ilicifolius, Egiceras corniculatum, Excoecaria agallocha and Rhizopora mucronata. The Muthupet mangrove wetland area is drained by the distrbutaries of the Cauvery viz., Paminiyar, Koraiyar, Kandankurichanar, Kilathangiyar and Marakkakoraiyar and forms a large lagoon before reaching the sea. A fieldwork has been carried out twice in a year representing Pre monsoon (June, 2006) and Post monsoon (Jan, 2007). The depth of sample collection ranges from 1.0 mts to 3.5 mts. A total of forty-eight sediment samples were collected with the help of Van veen grab and by using motor boat from the selected sites of the study area. The classification proposed by Hartmann and Puri (1974) has been followed in the present study, through which 35 ostracod taxa belonging to 24 genera, 17 families, 2 superfamilies and 2 suborder of the order Podocopida have been identifed. Bass lerites liebaui, Jankeijcythere mckenziei, Kalingella mckenziei, Neomonoceratina jaini are endemic to Indian waters only. Neomonoceratina iniqua is recorded in all the samples collected and studied. It outnumbered the entire ostracod population and represented by above 90% of the total population in few samples. Hemicytheridea paiki is represented second to N. iniqua in the study area. Some ostracod species characteristic of brackish water such as Hemicytheridea and Neosinocythere dekrooni occur in the creek. The occurrence of Cytherelloidea leroyi, Keijella reticulate and Neocytheretta murilineata, may be due to the tidal influence. All the species are well preserved. In general, the recorded ostracod assemblage is strongly of tropical, shallow and brackish water habitat in nature

Relationship Between Metabolic Components (Fasting Blood Glucose and Blood Pressure) and Normal-Tension Glaucoma (NTG).

Glaukoma merupkan sekelompok penyakit mata yang terkait dengan kerusakan struktural khas pada saraf optik karena tekanan intraokular yang terlalu tinggi (IOP). Sindroma metabolik (MS) didefinisikan sebagai sekelompok faktor risiko serangan jantung seperti diabetes, pra-diabetes, obesitas, kolesterol tinggi dan tekanan darah tinggi. Tujuan dari penelitian ini adalah untuk mengetahui hubungan antara komponen metabolisme (glukosa darah puasa dan tekanan darah) dan normo-tensi glaukoma. Penelitian ini adalah penelitian observasional dengan pendekatan cross-sectional. Sampel (30) diambil secara dari pasien di Poli Mata RS Saiful Anwar yang didiagnosis dengan sindroma metabolik. Kadar glukosa puasa dan tekanan darah mereka diukur. Mereka kemudian dikirim ke Poli mata divisi Glaukoma dan Neurooftalmologi untuk menguji normo-tensi glaukoma. Uji Shapiro-Wilk digunakan karena datanya kurang dari 50. Ada hasil yang menunjukkan sig = 0,000 <0,05. Dengan demikian, data tidak terdistribusi secara normal dan uji Mann-Whitney digunakan. Signifikansi SBP adalah 0,318, DBP 0,316 dan FBG adalah 0,191 yang lebih dari 0,05 (sig.> 0,05). Karena data tidak terdistribusi normal, dinormalisasi dan T-test digunakan. Hasil penelitian menunjukkan nilai signifikansi SBP, DBP dan FBG masing-masing adalah 0,955, 0,253 dan 0,293 yaitu> 0,05. Berdasarkan hasil, disimpulkan bahwa komponen metabolisme, glukosa darah puasa dan tekanan darah tidak memiliki hubungan yang signifikan dengan normo-tensi glaukoma

Effect of Gamma Irradiation on Growth Parameters of Vegetable Cowpea (Vigna unguiculata L. Walp)

Aim: The present investigation was carried out to study the effect of gamma irradiation on the growth parameters of cowpea variety Paiyur-1.Seeds were irradiated with physical mutagen viz., gamma irridation. The doses of radiation used were control, 50 Gy, 100 Gy, 150 Gy, 200 Gy, 250 Gy, 300 Gy, 350 Gy, and 400 Gy.Finding the LD50 and GR50 value for the physical mutagen dosages is the study's major goal. Cs137 is exposed to gamma radiation, and the observation were recorded in the M1 generation. Study Design: The regression method by applying Probit analysis based on rates of fatalities was utilised to estimate the Lethal Dose (LD50). Simple Linear Regression on the dose-response curve was adopted to evaluate the GR50 incorporating all of the vegetative parameters using R software. Place and Duration of Research: The study was carried out at Horticulture orchard, Department of Vegetable Science, Horticulture College and research Institute, Tamil Nadu Agricultural University, Coimbatore during 2022-2023. Methodology: In this study, the paiyur-1 variety of cowpea was sown with two replications, those mutagenized seeds were planted individually in germination paper using the roll towel method and dry seeds that weren't irradiated served as the control. To find the lethal dose 50 and to observe the shoot length, root length, germination percentage, mortality rate and seed vigour. Results: Among the 9 gamma irradiated treatments, 50Gy and 100 Gy exhibited superior germination percentages, despite the fact 50 Gy treated seeds were having appealing shoot length, root length, and plant height. The linear relationship have given that shoot length and root length are the two parameter that are highly susceptible to gamma irradiation than plant height and seed vigour

2-Amino-1-methyl-4-oxo-4,5-dihydro-1H-imidazol-3-ium 3-carboxy-4-hydroxybenzenesulfonate monohydrate

The asymmetric unit of the title molecular salt, C4H7N3O+·C7H5O6S−·H2O, contains a 5-sulfosalicylate anion, a creatininium cation and a water molecule of crystallization. The cation is protonated at the imidazole N atom and the anion is deprotonated at the sulfonic acid group. The creatininium is disordered over two sets of sites with refined site occupancies of 0.771 (3) and 0.229 (3). The benzene ring is approximately orthogonal to the disordered five-membered rings [dihedral angles of 89.7 (2) and 88.3 (8)° for the major and minor occupancy components, respectively]. In the crystal, the ions are connected through pairs of N—H...O hydrogen bonds, generating an R22(8) ring-motif. An intraionic O—H...O hydrogen bond generates an S(6) graph-set motif. Weak C—H...O contacts link the ions and water molecule into a two-dimensional network parallel to (001). The structure was refined as a two-component twin

Studies on floral morphology in different genotypes of Jasminum sambac

Not AvailableThe present investigation was undertaken to study the floral morphology behavior among 22 genotypes of Jasminum sambac. Results revealed that among the different genotypes, cluster bearing habit in terminal position was recorded in genotypes Iruvatchi and IIHR JS - 5, whereas other genotypes recorded forked cymes of cluster flowers in terminal and axillary. Three different shapes of flower bud was recorded among the genotypes, viz. pointed and long, pointed and short, rounded and short. Flower bud colour and colour on flower bud opening was white (155 B or 155 C) and pink tinge on flower bud was recorded in IIHR JS - 5. Star and round shaped flower was observed among different genotypes. Three different types of flowers were recorded, viz., single, double and multi-whorled (3 to 6). Among 22 genotypes, Arka Aradhana recorded longest bud (3.85 cm) and corolla (2.11 cm). The genotype IIHR JS - 5 recorded the longest corolla tube (2.29 cm) and Iruvatchi recorded maximum number of forks per cyme (14). Maximum number of calyx lobe was recorded in Gundumallige (8.79 cm), whereas longest calyx lobe was recorded in Soojimalli (1.49 cm). Bigger size of flower was recorded in Soojimalli (4.64 cm) and maximum number of petals was observed in IIHR JS - 1 (40). The information generated on floral morphological traits in different genotypes will facilitate the planned crop improvement programmes in jasmine.Not Availabl

Studies on pollen viability in Jasminum spp.

Not AvailableIn vitro studies on pollen viability of six jasmine species, viz. Jasminum sambac, J. auriculatum, J. grandiflorum, J. multiflorum, J. flexile and J. malabaricum, was conducted at ICAR-Indian Institute of Horticultural Research, Hesaraghatta Lake Post, Bengaluru during 2016-17. Results revealed that species Jasminum malabaricum recorded highest pollen viability (96.57%) as well as pollen germination (91.58%) followed by J. flexile (84.92% and 81.86%, respectively) and J. auriculatum (71.32% and 71.08%, respectively) under in vitro condition. The species J. sambac significantly recorded lowest pollen viability (34.27%) and germination (34.09%). Significantly highest normal shaped pollen grains were observed in J. auriculatum (96.92%) which was at par with J. malabaricum (96.89%) and J. grandiflorum (93.63%). Modified BK germination medium containing 100 ppm H3BO3 + 300 ppm Ca(No3)2 + 200 ppm MgSO4 with 10% sucrose + 15% PEG 4000 solution was found optimal for highest in vitro germination in J. malabaricum (91.58%). However, maximum length of pollen tube was recorded in J. flexile (1170.68 μm) followed by J. malabaricum (951.11 μm). The viable pollen diameter of different species ranged from 38.25 μm (J. auriculatum) to 46.53 μm (J. malabaricum). Pollen grains collected during evening (05:00 pm to 06:00 pm) at the time of anthesis showed best results. Pollen tubes revealed abnormalities such as bulging and coiling of tips in J. sambac and J. grandiflorum. This might be one of the reasons for no fruit set when J. sambac used as pollen parent. From this in vitro pollen germination study, species J. malabaricum, J. flexile and J. auriculatum were identified as most suitable male parents compared to other species.Not Availabl
