As cases of COVID-19 climb worldwide, academic medical centers (AMCs) are scrambling to balance the increasing demand for medical services while maintaining safe learning environments. The scale and nature of the current pandemic, limitations on key resources, risks of transmission, and the impact on trainee wellbeing pose additional challenges to AMCs. We propose aframework for AMCs to utilize in facilitating health system, organization and program-level adjustments to meet the needs of medical trainees during the pandemic.
In February 2020, we developed athree-level approach to the pandemic response of training programs at our AMC. The first level involved AMC alignment and engagement with regulatory stakeholders. The second level utilized the graduate medical education committee and leveraged organizational functions such as human resources, finance, and clinical departments. The third level of intervention focused on common approaches used by programs to ensure continuity of learning in the context of dynamic changes in workflows and service operations.
Outcomes at each level are reported. These include the co-development of anational framework on medical trainee responses to COVID-19, the composition of an operational guidance document, organizational protocols to accommodate novel challenges posed by the pandemic, and multiple program-level interventions.
This methodical approach, employed during aglobal crisis, was critical in facilitating interventions required to fulfill the mission of AMCs. Future steps include assessing the impact of these changes on trainee performance and the applicability of the approach in diverse settings.

Berberine due to its properties like antibiotic, immunostimulant, antitumor, antimotility, and positive effect on neurological disorders can be used to enhance peripheral nerve injuries. In this study, alginate/chitosan hydrogel containing different concentrations of berberine (0, 0.1, 1, 10% (w/v)) was created, evaluated, and applied as a scaffold for sciatic nerve regeneration. To prepare hydrogel, sodium alginate was dissolved in distilled water and cross-linked with CaCl2, and chitosan was dissolved in acetic acid and cross-linked with β-glycerol phosphate. The structure, release, swelling, weight loss, cytocompatibility, and hemocompatibility of the prepared hydrogels were assessed. The sciatic nerve crush was created in rats and fabricated hydrogels were injected, and functional analysis was used to evaluate their effectiveness. The results of physical characterization of the hydrogel indicated that the initial average pore size was about 39 μm and about 70% of the main weight of hydrogels was lost after incubation for 21 days and hemocompatibility of hydrogels was also confirmed. The MTT assay showed the cytocompatiblity of hydrogels and also indicated that berberine has dose-dependence effect on cell proliferation. The in vivo results showed the positive effect of berberine especially the hydrogel contained 1% of berberine on regeneration of sciatic nerve. buy Molidustat Based on this study, Alg/Chit hydrogel can be applied as a treatment to heal peripheral nerve injuries.

The objective of this study was to evaluate real-world effectiveness of latanoprostene bunod (LBN) ophthalmic solution 0.024% in treatment-naïve patients newly diagnosed with open-angle glaucoma (OAG) or ocular hypertension.
This multicenter retrospective chart review included patients aged ≥ 18years, with no history of medical, laser, or surgical intraocular pressure (IOP)-lowering intervention and at least two follow-up visits (spanning ≥ 2months) following initiation of LBN treatment. Extracted data included age, sex, race, cup-to-disk ratio, central corneal thickness, IOP, visual acuity (VA), concomitant medications, and adverse events. In patients treated bilaterally, the eye with the higher baseline IOP was the study eye.
Medical charts for 65 patients (mean [SD] age, 59 [14] years; 53.8% female) encompassing 125 eyes treated with LBN were reviewed across nine clinical sites. Mean (SD) IOP at baseline was 21.7 (5.9) mmHg. Mean days to first and second follow-up visit were 43 and 141, respectively. LBN use resulted in a mean (SD) reduction from baseline of 7.1 (4.7) and 7.3 (5.1) mmHg at the first and second follow-up visits, respectively (P < 0.0001 for both). Reductions among patients with IOP > 21mmHg (n = 30) at baseline were 10.0 (4.5) and 11.1 (4.6) mmHg at the first and second follow-up visits (P < 0.0001 for both). There were no meaningful changes in VA. Adverse events appeared infrequent, with only one report of ocular redness.
In this real-world, retrospective chart review, LBN 0.024% use resulted in robust IOP lowering in newly diagnosed OAG patients new to treatment, and appeared well tolerated.

Role of Rubisco Activase in imparting thermotolerance to the photosynthetic apparatus under high temperature. Thus, to improve the grain filling, we need to fine tune these crucial enzymes and their regulation, which directly or indirectly affect spike photosynthesis. CO
fixation in cereals crops like bread wheat (Triticum aestivum L.) is also contributed by ear photosynthesis beside the other organs like leaves or the flag leaf. 1000-grain weight of three Indian wheat cultivars (cvs.) PBW343, K7903, and HD2329 were calculated under three treatments until maturity stage (i.e. removal of flag leaf, removal of awns and shaded spikes). We observed that awn removal showed a significant decrease in 1000-grain weight in all cultivars. To delve deeper into the biological and molecular pathways taking place underlying the awn physiology, we conducted the awn transcriptome analysis of thermosusceptible Indian wheat cv. PBW343 under heat stress (HS) at 42°C for 2h using RNA-sequencing (RNA-seq). Differential expression analysis revealed, 160 transcripts, out of these, 143 transcripts were significantly upregulated and 17 transcripts were repressed under HS conditions.
