Purpose: To assess the anterior scleral thickness (AST) and describe the presence of a visible supraciliary space (SCS) in central serous chorioretinopathy (CSC) patients by swept-source optical coherence tomography (SS-OCT).
Study Design: Cross-sectional comparative study.
Material And Methods: Three groups were studied: 1) 64 eyes of 54 patients with CSC with persistent subretinal fluid (SRF); 2) 42 fellow eyes of CSC patients without SRF; 3) 65 eyes of 65 controls matched by age, sex and axial length (AL). The AST was measured in the temporal and nasal quadrants at 0, 1, and 2 mm from the scleral spur by SS-OCT. The presence of a visible SCS was also assessed.
Results: No differences were observed in the AST0 among the three groups (p≥ 0.665). The temporal AST1 was significantly thicker in the CSC group (530.3 ±67.1 µm) than in the controls (505.5 ±73.9; p=0.041). Mean AST2 was also thicker in the CSC group and the fellow eyes both for the temporal (519.4 ±89.1 µm and 519.8 ±98.5 µm respectively) and nasal quadrants (564.2 ±124.9 µm and 570.5 ±131.0 µm) than in the controls (450.1 ±76.8 and 473.3 ±111.6 µm) (all p≤0.001). A visible SCS was detected in the eyes of 8 CSC patients, in 4 fellow eyes and only in 1 control eye.
Conclusions: AST measured by SS-OCT was significantly greater in CSC eyes than in healthy eyes. Also, a visible SCS was detected in CSC eyes. Thus, thicker sclera in CSC eyes could be associated with the physiopathology of this disease.

The RNase activity of MCPIP1 is essential for regulating cellular homeostasis, proliferation, and tumorigenesis. Our study elucidates the effects of downregulation of MCPIP1 expression and an RNase-inactivating mutation (D141N) on normal epithelial kidney cells, indicating that MCPIP1 expression is a key factor that suppresses neoplastic transformation. We observed that either expression downregulation or mutation of MCPIP1 significantly increased its clonogenicity and altered the expression of cancer stem cell (CSC) markers and factors involved in epithelial-to-mesenchymal transition (EMT).

We previously developed human CAR macrophages (CAR-M) and demonstrated redirection of macrophage anti-tumor function leading to tumor control in immunodeficient xenograft models. Here, we develop clinically relevant fully immunocompetent syngeneic models to evaluate the potential for CAR-M to remodel the tumor microenvironment (TME), induce T cell anti-tumor immunity, and sensitize solid tumors to PD1/PDL1 checkpoint inhibition. In vivo, anti-HER2 CAR-M significantly reduce tumor burden, prolong survival, remodel the TME, increase intratumoral T cell and natural killer (NK) cell infiltration, and induce antigen spreading.

Background: We performed a prespecified subgroup analysis of the CATIS-2 trial (China Antihypertensive Trial in Acute Ischemic Stroke II) to compare the effect of early versus delayed antihypertensive treatment on death and disability in patients with and without medical history of hypertension.
Methods: CATIS-2 is a multicenter randomized clinical trial conducted in 106 hospitals in China. The trial randomized 4810 patients with acute ischemic stroke within 24 to 48 hours of symptom onset and elevated systolic blood pressure between 140 and <220 mm Hg to receive antihypertensive treatment immediately after randomization or to discontinue antihypertensive medications for 7 days and then receive treatment on day 8.

Excitation-inhibition (E/I) imbalance is theorized as a key mechanism in the pathophysiology of epilepsy, with ample research focusing on elucidating its cellular manifestations. However, few studies investigate E/I imbalance at the macroscale, whole-brain level, and its microcircuit-level mechanisms and clinical significance remain incompletely understood. Here, the Hurst exponent, an index of the E/I ratio, is computed from resting-state fMRI time series, and microcircuit parameters are simulated using biophysical models.

Purpose: To investigate the morphologic and functional outcomes of nanosecond subthreshold (ST) laser treatment for patients with chronic central serous chorioretinopathy (CSC).
Methods: In this prospective study, 44 patients were treated with the ST nanosecond laser with a follow-up period of 12 months. All target variables were measured at 1, 3, 6 and 12 months after the first laser treatment.
