Morphological And Biochemical Characterization Of Endophytic Bacteria From Selected Medicinal Plants Found At The University Of Dar Es Salaam, Tanzania, Ibrahim Juma Oct 2025

Morphological And Biochemical Characterization Of Endophytic Bacteria From Selected Medicinal Plants Found At The University Of Dar Es Salaam, Tanzania, Ibrahim Juma

Tanzania Journal of Science

Endophytic bacteria are capable of colonising internal tissues of medicinal plants, and producing secondary metabolites (biochemical compounds) of beneficial importance like the ones produced by their host plants. Though Tanzania harbours a wide species of medicinal plants with endophytic bacteria capable of producing such important bioactive substances, research on these bacteria remains scant, which limit their biotechnological applications. This work was undertaken to isolate and document endophytic bacteria from tropical almond, local avocado, banana and blue snake weed plants found at the University of Dar es Salaam, main campus.

Perioperative Benefits Of Dexmedetomidine As An Antiarrhythmic Agent In Noncardiac Surgical Patients: A Case Report, Sara Jaison, Kusuma Halemani

Sultan Qaboos University Medical Journal

Dexmedetomidine (DEX), a selective α2-adrenergic receptor agonist, has gained recognition for its sedative, anxiolytic, and sympatholytic properties, making it a valuable perioperative agent. This report describes the anaesthetic management of an elderly 75-year-old male patient with septic shock, multi-organ dysfunction, delirium and significant ventricular arrhythmias who presented in 2025 to a tertiary care teaching hospital in Oman and was scheduled for an emergency below-knee amputation. DEX was utilised for intraoperative sedation and its antiarrhythmic effects. Traditional sedatives often exacerbate delirium or pose cardiorespiratory risks; however, DEX provides effective sedation while preserving respiratory function and promoting haemodynamic stability. Notably, its …

Food and Machinery

[Objective] To study the nutritional components and in vitro antioxidant activities in different parts of Eucommia ulmoides. [Methods] The content of protein, fat, ash, vitamin C, polysaccharides, flavonoids, and chlorogenic acid in different parts of E.ulmoides is determined according to the methods specified in national standards. The antioxidant activities of different parts of E.ulmoides are evaluated based on the ABTS+ free radical scavenging ability, DPPH free radical scavenging ability, and total reducing power. [Results] There are statistical differences in the content of essential nutrients among different parts of E.ulmoides (P<0.05). The ash content and fat content are the highest in the leaves, reaching 13.65 and 6.19 g/100 g, respectively. The protein content and Vc content are the highest in male flowers, reaching 20.8 and 13.9 g/100 g, respectively. The total flavonoids, chlorogenic acid, and polysaccharides are the highest in the leaves, reaching 2.45, 1.61, and 1.27 g/100 g, respectively. The results of in vitro antioxidant activity assay show that male flowers have the highest total reducing power, with the IC50 of 10.2 μg/mL. The leaves have the highest ABTS+ free radical scavenging ability and DPPH free radical scavenging ability, with IC50 being 11.19 and 11.40 μg/mL, respectively. The comprehensive evaluation results of membership function method show that the antioxidant effect of the leaves is the best, and that of the cortex is the weakest. [Conclusion] The nutritional value and antioxidant properties of E.ulmoides vary among cortex, leaves, and male flowers. E.ulmoides leaves with both edible and medicinal properties demonstrate certain nutritional value in the development and utilization of food raw materials in the future.
