Zero Order Spectrophotometric Method for Estimation of Escitalopram Oxalate in Tablet Formulations

A new, simple, fast and reliable zero order spectrophotometric method has been developed for determination of Escitalopram Oxalate in bulk and tablet dosage forms. The quantitative determination of drug was carried out using the zero order values (absorbance) measured at 238 nm. Calibration graph constructed at 238 nm was linear in concentration range of 2-20 µg/ml with correlation coefficient 0.9999. The method was found to be precise, accurate, specific, and validated as per ICH guidelines and can be used for determination of Escitalopram Oxalate in tablet formulations

Length-weight relationship of five species of Nemipteridae family along the Gulf of Mannar, Eastern Indian Ocean

The parameters 'a' and 'b' of the length-weight relationship of five Nemipteridae species viz., Nemipterus bipunctatus (Valenciennes, 1830), Nemipterus randalli Russell, 1986, Scolopsis bimaculata Ruppell, 1828, Scolopsis xenochrous Gunther, 1872 and Scolopsis vosmeri (Bloch, 1792) are reported from the Gulf of Mannar, Eastern Indian Ocean. The fish samples were collected fortnightly from the trawlers of Thoothukudi Fishing Harbour between September 2020 and June 2021. The trawlers operate at a depth of 40–150 m with a 2–2.30 hours hauling period. These are operating bottom trawl nets and have a total length of 40 m with a cod-end mesh size of 35 mm. The total length of the fish was measured to the nearest 0.1 cm and weight to the nearest 0.01 g, respectively. The descriptive statistics and estimated length-weight relationships (LWRs) parameters were detailed in the paper

Range Extension of Parascolopsis baranesi Russell & Golani, 1993 to the Gulf of Mannar, East coast of India

Specimen of the family Nemipteridae was collected on 21st December 2020 from Thoothukudi Fishing Harbour (TFH), (Lat. 8°43′26.7", Long. 78°56′ 23.12" E; Depth: 250 to 325 m), Southern Coast of Tamil Nadu, India. The morphometric measurements and meristic counts of the specimen were recorded for identification by following the standard methods. The specimen was identified as Parascolopsis baranesi Russell and Golani in Isr J Ecol Evolut 39(4):337–347, 1993, which was distinguishable from all other species of Parascolopsis as it has distinctive prominent red blotch between the 7th and 10th dorsal spines; pinkish to whitish pectoral, pelvic, and anal fins and yellowish caudal fin with reddish base and margin. This study, for the first time, reports P. baranesi from India's East Coast. Currently, the distribution of this species extends to the Gulf of Mannar, India, from the Southwest coast. The present paper also reports and discusses a detailed description of the recorded specimen
