Tumour spectrum in -related Proteus syndrome: a systematic review of clinical reports and series.

-related Proteus syndrome is an ultra-rare mosaic overgrowth disorder with tumour predisposition. We conducted a systematic review to determine the range and characteristics of these tumours. A systematic review was conducted to identify clinical reports and clinical series of Proteus syndrome published between 1983 and 2023.

Definitive Evidence for the Identification and Function of Renin-Expressing Cholinergic Neurons in the Nucleus Ambiguus.

Background: The importance of the brain renin-angiotensin system in cardiovascular function is well accepted. However, not knowing the precise source of renin in the brain has been a limitation toward a complete understanding of how the brain renin-angiotensin system operates.

Methods: Highly sensitive in situ hybridization techniques and conditional knockout mice were used to address the location and function of renin in the brainstem.

Glenn circulation causes early and progressive shunting in a surgical model of pulmonary arteriovenous malformations.

Pulmonary arteriovenous malformations (PAVMs) universally develop in patients with single ventricle congenital heart disease. Single ventricle PAVMs have been recognized for over 50 years but remain poorly understood. To improve our understanding, we developed a surgical rat model of Glenn circulation and characterized PAVM physiology over multiple time points.

Preferential occurrence of fast radio bursts in massive star-forming galaxies.

Fast radio bursts (FRBs) are millisecond-duration events detected from beyond the Milky Way. FRB emission characteristics favour highly magnetized neutron stars, or magnetars, as the sources, as evidenced by FRB-like bursts from a galactic magnetar, and the star-forming nature of FRB host galaxies. However, the processes that produce FRB sources remain unknown.

Religious leaders' nuanced views on birth spacing and contraceptives in Sierra Leone - qualitative insights.

Background: Sierra Leone is a religiously diverse country, with Christianity and Islam being the dominant faiths. This religious landscape plays a significant role in shaping attitudes towards family planning and contraceptives. We examined religious leaders' knowledge of family planning and modern contraceptive methods.
