Three simple and sensitive spectrophotometric methods are proposed for the determination of atenolol (ATN) in bulk drug and tablets. The methods are based on the bromination of ATN by the bromine generated in situ by the action of the acid on the bromate-bromide mixture followed by the determination of unreacted bromine by reacting with a fixed amount of either meta-cresol purple (MCP) and meas...

Phoenicoprocta capistrata (Fabricius 1775) (Lepidoptera: Arctiidae) is an arctiid moth reported for the Caribbean and Brazil, whose immature stages and life cycle are unknown. In this study, and for the first time, a host plant is registered and the immature stages and the captivity life cycle are described using a Cuban population. Larvae feed on fowlsfoot, Serjania diversifolia (Jacq.) Radlk ...

On reaction of 2,2'-bipyridine with iridium(iii), an "aggregation induced phosphorescence (AIP)" active "rollover" complex, [Ir(PPh3)2(bipy-H)(Cl)(H)] (bipy-H = κ(2)-N,C-2,2'-bipyridine) or [Ir(bipy-H)], is obtained. The emission colour changes from bluish-green to yellowish-orange and vice versa after repeated protonation and deprotonation of [Ir(bipy-H)], respectively, which unequivocally sup...

A 28‐year‐old male presented with a 1‐year history of multiple, raised, reddish lesions over the right eye and right forearm. There was no other significant history. On examination, multiple, discrete, shiny, reddish brown papules were present over the right eye and the anteromedial aspect of the right forearm. Few lesions over the forearm were grouped together forming a small plaque [Figure 1]...

Nitric oxide (NO) has been known as a gaseous chemical mediator, which modulates several physiological functions. Spatial and temporal control of NO release facilitates further study and medical application of NO. Herein, we report design and synthesis of a novel NO donor, NO-Rosa. NO-Rosa has a rosamine moiety, which absorbs yellowish green light. Upon irradiation with yellowish green light (5...

Morphological studies showed that tree shape in Bitter sweet orange and Yuma citrange was spheroid with spreading growth habit and wide branch angle. Leaves were simple with dark green color, medium size and brevipetiolate in Sour orange while Yuma citrange had trifoliate leaves with medium and green color. Bitter sweet orange had the highest leaf lamina length (10.4 mm) than other rootstocks. ...

Acute chest syndrome (ACS) is the leading cause of ICU admission in patients with sickle cell disease and is characterized by golden sputum, which is commonly attributed to the presence of bilirubin. Three young consecutive patients with homozygous sickle cell disease were admitted for severe acute respiratory syndrome due to ACS. In all 3 patients, tracheal secretions and bronchoalveolar lavag...

AIMS Endomyocardial biopsy is essential for definite diagnosis of idiopathic myocarditis. However, since endomyocardial biopsy is guided by fluoroscopy, whether or not the diseased myocardium is biopsied depends on chance, and this may lead to misdiagnosis. If the endocardial surface represents changes indicative of stages of myocarditis, staging of myocarditis and targeted cardioscope-guided b...
