Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory vascular disease of medium-sized arteries that causes abnormal cellular growth in arterial walls and most commonly affects young to middle-aged women (20-50 years of age). While FMD often involves the renal arteries, it can affect any arterial bed. FMD has a characteristic angiographic appearance of a "string of beads.

Thalamic hemorrhage is a type of intracerebral hemorrhage with high disability and mortality rates. Because of its deep bleeding location, irregular shape of the hematoma, and compression of the third ventricle, it is not suitable for craniotomy. This paper reports a case of a 63-year-old male patient who sought medical attention for left-sided basal ganglia and thalamus hemorrhage that broke into the ventricles.

There has been limited exploration of carbon nanofiber as a scaffold for cellular attachment and proliferation. In this work, commercially available, pyrolytically stripped carbon nanofiber (cCNF) is deposited over electrospun nanofiber mats, polycaprolactone (PCL) and poly(D-lactide) (PDLA), to immobilize them and investigate whether the 3D cCNF layer's surface augments cell proliferation of human dermal fibroblasts (nHDF). Spectral characterizations, such as XRD and Raman, show that cCNF exhibited crystalline structure with a high graphitization degree.

In the subauroral zone at the boundary of the auroral oval in the evening and night hours during geomagnetic disturbances, a narrow (about 1°-2°) and extended structure (several hours in longitude) is formed. It is known as a polarization jet (PJ) or the subauroral ion drift (SAID). The PJ/SAID is a fast westward ion drift and is one of the main signatures of a geomagnetic disturbance in the subauroral ionosphere at the altitudes of the F-layer, when the geomagnetic AE index reaches more than 500 nT.

The healing of bacteria-infected wounds has long posed a significant clinical challenge. Traditional hydrogel wound dressings often lack self-healing properties and effective antibacterial characteristics, making wound healing difficult. In this study, a bioactive small molecule cross-linking agent 4-FPBA/Lys/4-FPBA (FLF) composed of 4-formylphenylboronic acid (4-FPBA) and lysine (Lys) was utilized to cross-link guar gum (GG) and a tannic acid/iron (TA/Fe) chelate through multiple dynamic bonds, leading to the formation of a novel self-healing hydrogel dressing GG-FLF/TA/Fe.
