Not your typical abdominal pain: Case report of a fisherman presenting to the trauma & emergency surgery department with intestinal perforation due to an eel fish.

Background: Traumatic intestinal perforation by foreign bodies is rare, with cases involving live fish being exceedingly uncommon, with only one reported case to date. We present a unique case of a 55-year-old fisherman who presented to the Emergency Department with traumatic intestinal perforation due to an eel fish accidentally entering his rectum. Despite initial reluctance to seek medical attention, prompt intervention was crucial to addressing peritonitis.

Binding of ibuprofen to human hemoglobin: elucidation of their molecular recognition by spectroscopy, calorimetry, and molecular modeling techniques.

Ibuprofen, used for the treatment of acute and chronic pain, osteoarthritis, rheumatoid arthritis, and related conditions has ample affinity to globular proteins. Here we have explored this fundamental study pertaining to the interaction of ibuprofen with human hemoglobin (HHb), using multispectroscopic, calorimetric, and molecular modeling techniques to gain insights into molecular aspects of binding mechanism. Ibuprofen-induced graded decrease in absorption spectra indicates protein disruption along with sedimentation of HHb particle.

Cigarette smokers develop altered erythrocyte membrane composition: an investigation unmasking the role of membrane bound integral protein GLUT 1.

Erythrocytes in cigarette smokers are prone to oxidative damage. Here, we sought to elucidate the facts behind modifications and possible defense system developed in erythrocyte of cigarette smokers. We observed significant increase in stomatocytes and spherocytes, and osmotic fragility of erythrocyte, along with reduced level of protein thiol and increased fluorescence anisotropy in isolated membrane.

Underlying molecular interaction of bovine serum albumin and linezolid: a biophysical outlook.

Linezolid, one of the reserve antibiotic of oxazolidinone class has wide range of antimicrobial activity. Here we have conducted a fundamental study concerning the dynamics of its interaction with bovine serum albumin (BSA), and the post binding modification of the later by employing different spectroscopic (absorption, fluorescence and circular dichroism (CD) spectroscopy) and molecular docking tools. Gradual quenching of the tryptophan (Trp) fluorescence upon addition of linezolid to BSA confirms their interaction.

Acetaminophen interacts with human hemoglobin: optical, physical and molecular modeling studies.

Acetaminophen, a widely used analgesic and antipyretic drug has ample affinity to bind globular proteins. Here, we have illustrated a substantive study pertaining to the interaction of acetaminophen with human hemoglobin (HHb). Different spectroscopic (absorption, fluorescence, and circular dichroism (CD) spectroscopy), calorimetric, and molecular docking techniques have been employed in this study.

Cigarette smokers develop structurally modified hemoglobin: a possible way of increasing oxidative stress.

Context: Increased levels of free radicals and various reactive species along with reduced antioxidant defence system are the major threat to erythrocyte in tobacco smokers. Thus, the hemoglobin (Hb) within the erythrocyte is very prone to oxidative damage. Earlier reports suggest that cigarette smoking is related with the glutathionylation and formation of adducts of Hb.
