Purpose: To describe features of a syphilitic vascularized iris mass on multimodal imaging and its resolution after penicillin treatment.
Methods: Observational case report and literature review of syphilitic iris masses.
Results: A 43-year-old woman presented with a unilateral vascularized tan iris mass in the setting of bilateral panuveitis that occurred along with bilateral papillitis, cystoid macular edema and retinal vasculitis. Laboratory work-up confirmed a diagnosis of syphilis. Ultrasound biomicroscopy (UBM) of the iris mass showed parapupillary hyperechoic full-thickness iris stromal thickening with small intrinsic circular lumens without cyst or ciliary body extension, while the anterior segment optical coherence tomography (AS-OCT) demonstrated a hyperreflective mass with deep iris extension and partial hyporeflective rim. Following treatment, the mass fully resolved without residual sequela. A review of literature identified 11 additional cases of syphilitic iris masses in the English literature from 1915 to present. Their presentations and clinical courses were reviewed herein.
Conclusions: This report characterizes a syphilitic iris mass on slit-lamp photography, iris fluorescein angiography, UBM and AS-OCT; depicts key characteristics of syphilitic iris masses; and highlights the need for close inspection of the iris mass as an uncommon sign of ocular syphilis.

Plants play a key role in the ecological restoration of urban wetlands. Previous studies have shown that heavy-metal accumulation capacities and adaptation strategies of wetland plants may be related to their life forms. In this study, pot experiments were conducted to investigate the effects of nitrogen (N) on the adaptation strategies of two evergreen and deciduous aquatic iris life forms under cadmium (Cd) stress.

Calcium (Ca)-enhanced organic matter (OM) fouling of nanofiltration (NF) membranes leads to reduced flux during desalination and requires frequent cleaning. Fouling mechanisms are not fully understood, which limits the development of targeted fouling control methods. This study employed synchrotron-based X-ray fluorescence (XRF) and X-ray absorption near-edge structure (XANES) spectroscopy to quantify the spatial distribution and mass of Ca deposition as well as changes in the Ca coordination environment characteristic of specific fouling mechanisms, respectively.

Biocatalytic degradation of micropollutants has been extensively explored in both batch and membrane reactors in µg/L to mg/L concentrations and variable water compositions. The degradation of micropollutants by biocatalytic membranes at environmentally relevant concentrations of ng/L range found in natural surface water matrices has not yet been investigated, presumably because of the challenging concentration analysis. This study investigated the limitations of biocatalytic degradation of estradiol (E2) micropollutant at environmentally relevant concentrations by a biocatalytic membrane.

Background: Mastectomy is the first single surgery that transgender men and nonbinary people frequently undergo. We present a prospective series of 155 cases of double incision mastectomy (DIM) with nipple-areolar complex (NAC) graft.
Methods: From January 2019 to December 2022, 165 outpatients were operated on, and 155 are included in the study.
