Pre and post adsorption phenomenon was confirmed by characterization of adsorbent using AFM, FTIR, SEM, and EDX analysis. The adsorbent MCSC has regenerative property and can be reused 3-4 times after treating with alkaline medium (0.2 N NaOH) and offered more than 60% removal of Cr (VI) at the fourth cycle. It can be inferred based on this study that MCSC is an effective adsorbent for Cr (VI) removal and can be used on an industrial scale for social and environmental benefit. Novelty statement An agriculture waste mixture of coconut shell and coir (MCSC) without the addition of any chemical reagent, was used for Cr(VI) removal. As per literature survey and best of our knowledge, the adsorbent MCSC has not been reported for Cr (VI) removal. In the previous study, authors reported either coconut coir pith or coconut shell or coconut charcoal as adsorbent for Cr (VI) removal. The adsorbent MCSC is efficient even at very low doses (0.1 g) as compared to the reported adsorbent.
To assess the vision-related quality of life in adult patients with a history of primary congenital glaucoma.
In a cross-sectional hospital-based study eligible patients with a history of primary congenital glaucoma aged more than 18 were recruited in the study. Patients with secondary glaucoma and monocular patients were excluded. All patients underwent a complete ophthalmologic examination. The subjects were requested to answer a Persian approved version of the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) questionnaire.
A total of 23 congenital glaucoma patients have enrolled in the study. The mean age was 29.22 (9.3 SD) and mean IOP was 13.82 (5.19 SD) and 15.69 (5.26 SD) in right and left eyes, respectively. The mean number of medications was 1.13 (1.25 SD) in the right and 1.30 (1.18 SD) in the left eyes. Among all scores of NEI-VFQ-25, the lowest score belonged to mental health 53.71 (29.72) and the highest score was color vision score 83.69 (20.79). We found a significant influence of visual field defect on many subscales including general health and general vision (
= 0.007,
= +0.65) and (
= 0.002,
= +0.71) respectively. The Mean Defect (MD) was associated with low social functioning and peripheral vision too (
= 0.035,
= +0.53) and (
= 0.001,
= +0.76) respectively. Age had a negative impact on the general vision subscale (
= 0.003,
= -0.59).
Our study showed that visual field defect was strongly associated with many subscales scores in (NEI VFQ-25) questionnaire.

Efficient and cost-effective technology for contaminants remediation relies on a tradeoff between several parameters such as removal efficiency, microorganism growth, and its tolerance to contaminant toxicity. NSC 19630 This article demonstrates the optimum conditions achieving the highest removal rates and the minimal growth inhibition in batch cultures of Picocystis using response surface methodology. A central composite face-centered (CCF) design was used to determine the effects on removal and growth inhibition of four operating parameters temperature, inoculum cell density, light intensity, and initial BPA concentration. Results showed that the maximal BPA removal was 91.36%, reached the optimal culture conditions of 30.7 °C, 25 × 105 cells ml-1 inoculum density, 80.6 µmol photons m-2 s-1 light intensity, and initial BPA concentration of 10 mg l-1. Various substrate inhibition models were used to fit the experimental data, and robustness analysis highlighted the Tessier model as more efficient to account for the interaction between Picocystis and BPA and predict removal efficiency. These results revealed how Picocystis respond to BPA contamination and suggest that optimization of experimental conditions can be effectively used to maximize BPA removal in the treatment process.HighlightsSurface response methodology was applied for optimization of BPA removal by the Chlorophyta Picocystis sp.Temperature, light intensity, inoculum cell density and initial BPA concentration were selected as factors that may affect BPA removal and microalgae growth.The optimal conditions for the maximum BPA removal and minimum growth inhibition were 30.7 °C; 80.6 µmol photons m-2 s-1; 25 × 105 cells ml-1 and 10 mg l-1 BPA.Teissier model was selected to fit the kinetic of BPA removal by Picocystis with R2 = 0.92.Rare facial clefts are characterized by facial involvement that is not restricted to the lip, palate, and alveolus as in traditional cleft lip and palate. The craniofacial skeleton and the orbital structures are frequently affected in these conditions. Exposure of the eyeball, when not early treated, puts the function and the preservation of the eye at risk. We report the case of a 2-month-old boy admitted to our service with an extensive oral-ocular cleft and exposure of the eyeball with melting corneal ulcer treated with a conjunctival closure with a purse-string suture.
While literature exists about persons who use injection drugs, few studies explore the experience of women who use these substances. Furthermore, even less research specifically focuses on the lives and experiences of homeless women who use injection drugs. What literature does exist, moreover, is often dated and primarily addresses concerns about infectious disease transmission among these women; and some highlight that these women have lives fraught with violence.
To update this knowledge and better understand the lives of women who use injection drugs in the Canadian context.
We undertook an exploratory qualitative study and we engaged in semi-structured interviews with 31 homeless women who use injection drugs in downtown Ottawa, Canada. We analyzed the data using the principles of applied thematic analysis.
Our data identified that violence pervaded the lives of our participants and that these experiences of violence could be categorized into three main areas early and lifelong experiences of violence; violence with authority figures (e.
