Anticancer Activity In Vitro of Sulfated Polysaccharides from the Brown Alga .

Sulfated polysaccharides SpvF1, SpvF2, SpvF3, and SpvF4 from the brown alga collected north of Hon Do (Nha Trang Bay, Vietnam) were isolated and studied. The structure of the obtained polysaccharide was studied using chemical methods and NMR spectroscopy. Fucoidans were low-sulfated (SpvF1, SpvF2) and medium-sulfated (SpvF3, SpvF4) heterogeneous polysaccharides.

Growth of Single Crystals of (KNa)NbO by the Self-Flux Method and Characterization of Their Phase Transitions.

In this study, single crystals of (KNa)NbO are grown by the self-flux crystal growth method and their phase transitions are studied using a combination of Raman scattering and impedance spectroscopy. X-ray diffraction shows that single crystals have a perovskite structure with monoclinic symmetry. Single crystal X-ray diffraction shows that single crystals have monoclinic symmetry at room temperature with space group P121.

Promising deep-red emitting Cr-doped SrAlO phosphors for plant growth LEDs.

Recently, deep-red-emitting phosphors that can be excited by ultraviolet (UV) and near-ultraviolet (NUV) light have been extensively investigated for plant growth LED applications. However, due to the harmful effects of these high-energy rays on plants, violet- or blue-excited deep-red-emitting phosphors are considered a more appropriate solution. In this work, SrAlO:Cr phosphors were synthesized using a simple solid-state reaction, revealing a strikingly sharp deep-red emission band centered at 694 nm and effective excitation by violet light.

Post-traumatic recurrent ulnar nerve dislocation at the elbow: a rare case report.

Introduction And Importance: Several authors have also made reference to a less prevalent condition known in elbow as ulnar nerve subluxation. However, this particular condition tends to manifest primarily in young individuals who engage in professional sports or activities involving extensive use of the forearm. A more severe form of ulnar nerve subluxation, which is ulnar nerve dislocation, gives rise to a characteristic dislocation and relocation of the nerve at the elbow during flexion and extension of the forearm.
