In this study, nanostructured hydroxyapatite (HAp) was successfully extracted from the bones of Priacanthus macracanthus (Red Big Eye), a species commonly processed in fish industry, generating significant waste. The extraction process utilized an alkaline hydrolysis method optimized with 2 M sodium hydroxide at 250 °C for 5 h, producing high-purity HAp. Fourier transform infrared spectroscopy (FT-IR) confirmed presence characteristic phosphate peaks 1044 cm⁻¹ and 963 cm⁻¹, hydroxyl 632...

Congenital hyperinsulinism (CHI) is the most frequent cause of severe, persistent hypoglycemia in infancy and childhood. We report a case CHI with diffuse pancreatic abnormality diagnosed preoperatively using 68Ga octreotide (DOTA NOC) positron emission tomography scan. Genetic analysis revealed homozygous ABCC8 splicing mutation. Subtotal (95%) pancreatectomy was done, infant remained euglycemic discharged on breast feeds. The patient continuously followed up asymptomatic until 9 months.

Multiple splenic abscesses are a condition associated with high mortality if there is delay in the diagnosis and initiation of specific treatment. Salmonella typhi as an etiological cause multiple distinct rarity. In past treatment for abscess including enteric fever was splenectomy however; conservative by percutaneous drainage increasingly being reported isolated now abscesses. We report child who presented successfully treated aspiration antibiotics.

ABSTRACT Background: Sepsis-induced acute kidney injury (AKI) is difficult to prevent because most patients are diagnosed after they develop it. Standard serum and urine creatinine levels insensitive nonspecific for detecting in its early stages. Glutathione S-transferase (GST) has received little attention as a biomarker AKI. Methods: This study included 65 adult with sepsis who developed oliguria within 72 h of admission. Baseline values were recorded at least 1 month before or intensive...

Abstract Background The anaesthetic agents can affect the quality of motor-evoked potential intraoperatively as they inhibit synaptic transmission. Intravenous anaesthetics suppress lesser than inhalational agents, so total intravenous anaesthesia or a combination with minimal supplementation is used when monitored. Motor-evoked get depressed at high doses propofol required to maintain surgical depth, hence, adjuvant like dexmedetomidine that depth without affecting are often required. This...
