Effect of cations on monochlorobenzene adsorption onto bentonite at the coexistence of Tween 80.

The effect of several prevalent cations (including Na, K, Mg, Ca, Al, and Fe) on the adsorption of monochlorobenzene (MCB) onto bentonite was investigated at the coexistence of nonionic surfactant Tween 80 (T80) in surfactant-enhanced remediation (SER). They are all favorable for MCB and T80 adsorption, especially Mg and Ca. Adsorption of MCB is strongly depended on T80 micelles.

The effect of Tween 80 on monochlorobenzene migration in bentonite.

Several studies conducted at industrial sites have documented the infiltration of dense non-aqueous phase liquids (DNAPLs) into clay layers, a phenomenon potentially influenced by the coexistence of chemicals like surfactants in some common pollutants. Bentonite (Ben), monochlorobenzene (MCB), and Tween 80 (T80) were selected as reference components to investigate the influences of nonionic surfactants on DNAPLs migration in clays. Results showed that T80 promotes MCB dissolution and encourages MCB adsorption on Ben.

Visual Recovery and Prognosis in the Treatment of Submacular Hemorrhage due to Polypoidal Choroidal Vasculopathy and Retinal Arterial Macroaneurysm: A Retrospective Study.

Purpose: This study was carried out to evaluate the visual acuity (VA), complications, and prognosis of patients diagnosed with submacular hemorrhage (SMH) from polypoidal choroidal vasculopathy (PCV) and retinal arterial macroaneurysm (RAM) treated by pars plana vitrectomy (PPV), subretinal tissue plasminogen activator (tPA), and air tamponade in vitreous cavity. It facilitates the development of generic treatment methods that can be widely used to improve vision and treat potential complications in patients with SMH, regardless of the underlying pathophysiological condition, such as PCV or RAM.

Methods: In this retrospective study, SMH patients were divided into two groups based on their diagnosis: (1) polypoidal choroidal vasculopathy (PCV) and (2) retinal arterial macroaneurysm (RAM).

Clinical characteristics of primary pars plana vitrectomy combined with air filling for rhegmatogenous retinal detachment.

To detect the prognostic factors associated with initial reattachment after primary pars plana vitrectomy (PPV) with air tamponade for rhegmatogenous retinal detachment (RRD). We retrospectively reviewed 92 eyes of 92 patients with RRD. All eyes underwent PPV with air tamponade and a follow-up of at least 6 months.

Inverted internal limiting membrane flap technique for retinal detachment due to macular holes in high myopia with axial length ≥ 30 mm.

To compare the efficacy of internal limiting membrane (ILM) flap covering to that of ILM flap insertion for the treatment of macular hole retinal detachment (MHRD) in highly myopic eyes with axial length (AL) ≥ 30 mm. We retrospectively analysed the medical records of 48 MHRD patients with high myopia (AL ≥ 30 mm). According to different surgical methods, the patients were divided into a covering group (23 eyes) and an insertion group (25 eyes).

Bordetella avium-associated endophthalmitis: case report.

Background: Bordetella avium, an aerobic bacterium that rarely causes infection in humans, is a species of Bordetella that generally inhabits the respiratory tracts of turkeys and other birds. It causes a highly contagious bordetellosis. Few reports describe B.

Preoperative Steroid Use in Rhegmatogenous Retinal Detachment Associated with Choroidal Detachment after 23-Gauge Vitrectomy.

Background: Rhegmatogenous retinal detachment associated with choroidal detachment (RRDCD) is rare and the prognosis is poor. This retrospective study evaluated the effect of preoperative steroid on the clinical outcome of patients with RRDCD receiving 23-gauge pars plana vitrectomy (PPV).

Methods: Sixty-six patients (67 eyes) with diagnosed RRDCD underwent 23-gauge PPV.

Autologous neurosensory retinal transplantation for recurrent macular hole retinal detachment in highly myopic eyes.

Purpose: To investigate the morphological and functional reconstruction of the macular fovea after autologous neurosensory retinal transplantation for recurrent macular hole retinal detachment (MHRD) in highly myopic eyes.

Methods: Ten consecutive cases of recurrent MHRD with high myopia were retrospectively reviewed. All eyes underwent pars plana vitrectomy combined with autologous neurosensory retinal transplantation and were followed up for at least 3 months after silicone oil extraction.
