To investigate the agreement and correlation of manual central foveal thickness (CFT) measurements using the Heidelberg Eye Explorer and ImageJ software.

Optical coherence tomography (OCT) images were identified. CFT was measured using the Heidelberg Eye Explorer caliper tool. Two independent graders measured the CFT of the same images using ImageJ software. A Pearson correlation coefficient, intraclass correlation coefficient, Bland-Altman plots, and coefficient of repeatability were used to assess the agreement and correlation between the Heidelberg Eye Explorer and ImageJ measurements.

One-hundred and twenty-two OCT images from 91 patients were analyzed. Mean CFT as measured using the Heidelberg caliper tool was 264.8 ± 113 µm. Using ImageJ software, graders 1 and 2 obtained mean CFT values of 267 ± 114.3 µm and 270 ± 114.8 µm, respectively. Pearson correlation revealed a strong correlation between the Heidelberg and Image J measurements (r = 0.999, p < 0.0001). Bland-Altman plots noted a less than 4 µm mean difference between Heidelberg and ImageJ CFT values (2.67 ± 3.46 and 3.72 ± 2.78 µm for graders 1 and 2, respectively).

There was strong agreement between the Heidelberg Eye Explorer and ImageJ software for manual CFT measurements. ImageJ may be a reliable tool for thickness measurements when proprietary OCT software is unavailable.

To study the clinical and visual outcomes of patients presenting with bacillary layer detachment (BLD) on optical coherence tomography (OCT) in blunt ocular trauma.

Retrospective observational study.

Clinical fundus photographs and OCT scans with Spectralis machine were reviewed to identify patients with blunt ocular trauma showing BLD.

Patients were further analyzed for changes in their anatomic features such as subretinal hemorrhage, intrabacillary layer bleed. subretinal fibrosis and choroidal rupture and reattachment of BLD, and visual outcomes over subsequent follow-up visits.

Of a total of 77 eyes with blunt ocular trauma, 6 (8%) eyes with BLD were identified. All patients were male with presenting visual acuity ranging from 6/9 to 2/60 (mean logMAR = 1.119; Snellen’s equivalent = 20/263). The time interval between trauma and presentation ranged from 1 to 7 days. Subretinal hemorrhage and choroidal rupture were noted in all 6 eyes. On OCT, foveal involvement by the BLD was noted in 5 eyes. Intrabacillary layer hemorrhage was noted in all patients. Reattachment of the bacillary layer and visual acuity improvement were noted in all eyes at the final visit. The time interval for resolution of BLD ranged from 2 to 10 days. Visual acuity of 6/36 or less was secondary to subretinal fibrosis close to the fovea and subfoveal choroidal rupture.

BLD in blunt ocular trauma is a rare finding, shows complete resolution, and appears not to influence visual or anatomic outcome.

Previously, we used a structural design approach to develop picomolar range miniproteins targeting the SARS-CoV-2 spike receptor-binding domain. Here, we investigated the capacity of modified versions of one lead miniprotein, LCB1, to protect against SARS-CoV-2-mediated lung disease in mice. Systemic administration of LCB1-Fc reduced viral burden, diminished immune cell infiltration and inflammation, and completely prevented lung disease and pathology. Alectinib concentration A single intranasal dose of LCB1v1.3 reduced SARS-CoV-2 infection in the lung when given as many as 5 days before or 2 days after virus inoculation. Importantly, LCB1v1.3 protected in vivo against a historical strain (WA1/2020), an emerging B.1.1.7 strain, and a strain encoding key E484K and N501Y spike protein substitutions. These data support development of LCB1v1.3 for prevention or treatment of SARS-CoV-2 infection.Necroptosis mediated by Z-nucleic-acid-binding protein (ZBP)1 (also called DAI or DLM1) contributes to innate host defense against viruses by triggering cell death to eliminate infected cells. During infection, vaccinia virus (VACV) protein E3 prevents death signaling by competing for Z-form RNA through an N-terminal Zα domain. In the absence of this E3 domain, Z-form RNA accumulates during the early phase of VACV infection, triggering ZBP1 to recruit receptor interacting protein kinase (RIPK)3 and execute necroptosis. The C-terminal E3 double-strand RNA-binding domain must be retained to observe accumulation of Z-form RNA and induction of necroptosis. Substitutions of Zα from either ZBP1 or the RNA-editing enzyme double-stranded RNA adenosine deaminase (ADAR)1 yields fully functional E3 capable of suppressing virus-induced necroptosis. Overall, our evidence reveals the importance of Z-form RNA generated during VACV infection as a pathogen-associated molecular pattern (PAMP) unleashing ZBP1/RIPK3/MLKL-dependent necroptosis unless suppressed by viral E3.Empathy is the ability to experience a shared affective state as others. It enhances group living and manifests itself as helping behavior towards a distressed person. It also can flourish by nurturing. Recent findings suggest that rodents exhibit empathy-like behavior towards their conspecifics. However, the role of early-life experiences (e.g., maternal care) is not clear on the development of empathy-like behavior. Moreover, brain-derived neutrophilic factor (BDNF) is a pivotal protein in modulating the brain’s function and behaviors. Evidence suggests that the expression of the BDNF gene can be affected by the quality of maternal care. In this study, we questioned whether variation in maternal care modulates empathy-like behavior of male rats in adulthood. Additionally, gene expression of BDNF was measured in the amygdala, hippocampus, insula, anterior cingulate cortex, prefrontal cortex, and striatum in these adult male rats. Based on the pattern of maternal care, the offspring were divided into high maternal care (HMC) and low maternal care (LMC) groups.
