Dyspnea with Hemidiaphragm Elevation in a Patient with Giant Cell Arteritis: A Case Report.

We herein report the first case of dyspnea with hemidiaphragm elevation in a 68-year-old woman with active giant cell arteritis (GCA), including successful treatment. Contrast-enhanced computed tomography showed a reduced density of the left ophthalmic artery and the left superficial temporal artery with increased soft tissue compared to the other side, indicating that the GCA had flared up and suggesting that the hemidiaphragm elevation might be caused by vasculitis-associated ischemia of the right phrenic nerve. Hemidiaphragm paralysis due to vasculitis-associated ischemia in patients with GCA needs to be distinguished from local infection, tumors, and hepatomegaly, which are the major causes of hemidiaphragm elevation.

Selective breeding is a potent method for developing strains with enhanced traits. This study compared the growth performance and stress responses of the genetically improved Abbassa Nile tilapia strain (G9; GIANT-G9) with a local commercial strain over 12 weeks, followed by exposure to stressors including high ammonia (10 mg TAN/L), elevated temperature (37 °C), and both for three days. The GIANT-G9 showed superior growth, including greater weight gain, final weight, length gain, specific growth rate, and protein efficiency ratio, as well as a lower feed conversion ratio and condition factor compared to the commercial strain.

Tetrahedral halides with broad transparency and large second harmonic effects have the potential to serve as mid-infrared wide-bandgap materials with balanced nonlinear-optical (NLO) properties. However, their regular tetrahedral motifs tend to exhibit low optical birefringence (Δ < 0.03) due to limited structural anisotropy, which constrains their practical phase-matched capability.

Background: Diagnosis of Giant Cell Arteritis (GCA) and Polymyalgia rheumatica (PMR) may be challenging as many patients present with non-specific symptoms. Superficial cranial arteries are predilection sites of inflammatory affection. Ultrasound is typically the diagnostic tool of first choice supplementary to clinical and laboratory examination.

Metal nanocrystals synthesized in achiral environments usually exhibit no chiroptical effects. However, by placing nominally achiral nanocrystals 1.3 nm above gold films, we find giant chiroptical effects, reaching anisotropy factors as high as ≈ 0.
