Buthionine sulfoximine acts synergistically with doxorubicin as a sensitizer molecule on different tumor cell lines.

The chemotherapeutic drug doxorubicin (DOX) has been widely used for treating solid tumors attributed to its antiproliferative effectiveness; however, its clinical use is limited due to side effects, including cardiotoxicity, myelosuppression, and drug resistance. Combining DOX with buthionine sulfoximine (BSO), a glutathione (GSH) synthesis inhibitor, showed promising results in overcoming these adverse effects, potentially reducing the required DOX dose while maintaining efficacy. The aim of the present study was to examine the effects of different concentrations of BSO and DOX, both individually and in combination, utilizing B16/F10 (murine melanoma), SNB-19 (human glioblastoma), S180 (murine sarcoma), and SVEC4-10 (murine endothelial) cell lines.

Iron overload has been shown to have deleterious effects in the brain through the formation of reactive oxygen species, which ultimately may contribute to neurodegenerative disorders. Accordingly, rodent studies have indicated that systemic administration of iron produces excess iron in the brain and results in behavioral and cognitive deficits. To what extent cognitive abilities are affected and which neurobiological mechanisms underlie those deficits remain to be more fully characterized.

Objectives: The aim of the study was to evaluate the association between triage body temperature (BT) and outcome in cats presenting to the emergency department (ED).
Methods: A retrospective observational study was conducted on cats presented to the ED. BT, clinical diagnosis and outcome were recorded.
Phototoxic reaction to oral terbinafine due to Tinea capitis in a child.
Acta Dermatovenerol Croat

We report the case of an 18-month-old boy who developed a phototoxic skin reaction to terbinafine on his scalp, ears, and face in the form of disseminated erythematous plaques, which resembled subacute lupus erythematosus (SCLE) in their clinical presentation. Skin changes appeared a short time after the boy was exposed to sunlight during the period of time when he was treated with oral terbinafine due to Microsporum canis fungal scalp infection. Tinea capitis is a common dermatophyte infection primarily affecting prepubertal children (1).

Pulmonary atresia with ventricular septal defect (PA-VSD) is usually diagnosed by transthoracic or fetal echocardiography, with the prenatal diagnosis being feasible and accurate if fetal cardiology services are available. The limitations of transthoracic echocardiography (TTE) in the evaluation of PA-VSD include the complete evaluation of the pulmonary arteries and patent ductus arteriosus, quantitative evaluation of the right ventricle size and function, and delineation of associated cardiac anomalies such as coronary artery anomalies, anomalies of systemic or pulmonary venous return, and complex arch anomalies. Echocardiography also has limitations in evaluating hemodynamics such as flow volumes, shunts, and regurgitant fraction.
