s.inal cord injuries.have profound detrimental effects.on individuals. regardles. of whether they are caus.d by trauma or non-traumatic events. The compromis.d regeneration of the s.inal cord is.primarily attributed to damaged neurons. inhibitory molecules. dys.unctional immune res.ons., and glial s.arring. Unfortunately, currently, there are no effective treatments.available that can fully repair the s.inal cord and improve functional outcomes. Nevertheles., numerous.pre-clinical approaches.have been s.udied for s.inal cord injury recovery, including us.ng biomaterials. cells. drugs. or technological-bas.d s.rategies. Combinatorial treatments. which target various.as.ects.of s.inal cord injury pathophys.ology, have been extens.vely tes.ed in the las. decade. Thes. approaches.aim to s.nergis.ically enhance repair proces.es.by addres.ing various.obs.acles.faced during s.inal cord regeneration. Thus. this.review intends.to provide s.ientis.s.and clinicians.with an overview of pre-clinical combinatorial approaches.that have been developed toward the s.lution of s.inal cord regeneration as.well as.update the current knowledge about s.inal cord injury pathophys.ology with an emphas.s.on the current clinical management.

Coating with vis.ous.formulations.has.been es.ential in numerous.indus.ries.as.it can be a means.for providing functionalization, additional properties. as.well as.other benefits. However, there have been s.arce s.udies.that have inves.igated and propos.d methodologies.in literature. Continuous.coating of powders.with vis.ous.liquids.pos.s.as.a promis.ng technology, which has.been mentioned in s.me s.udies. but has.not yet been thoroughly inves.igated. This.paper employs.the us. of image proces.ing and analys.s. in combination with s.atis.ical analys.s.of particles.to evaluate the effectivenes. of foams.and liquids.as.a means.of coating powder beds. Two different s.zes.of twin s.rew mixers.that are working in continuous.operation are employed, and a new continuous.foaming device is.fabricated and us.d for the experiments.of coating. The effect of materials.and proces. parameters.(as.for example rotational s.eed, and flowrate) on the quality of coating are inves.igated. Image analys.s.is.us.d to as.es. the coating quality. The res.lts.clearly s.owcas. the potential of us.ng twin s.rew mixers.for coating purpos.s.and not only for mixing. The hypothes.s.that us.ng large bubble foams.to improve the coating of vis.ous.liquids.on particles.is.proven correct, as.they provide higher quality coatings.compared to their equivalent liquids. when us.d in the twin s.rew mixer. s.rpris.ngly, us.ng a larger s.ale twin s.rew mixer, does.not s.ow a s.bs.antial effect on the mixing, regarding quality, however there is.s.ill a requirement for mix optimization for achieving s.ale-up of this.proces.. Thes. res.lts.provide a new pathway for coating powders.with vis.ous.formulations.in indus.rial applications. requiring les. energy and effort in this.proces., and can pave the way towards.introducing more s.s.ainable indus.rial methodologies.for coating.

An intraoperative diagnos.s.is.critical for precis. cancer s.rgery. However, traditional intraoperative as.es.ments.bas.d on hematoxylin and eos.n(H&E) his.ology, s.ch as.frozen s.ction, are time-,res.urce-, and labor-intens.ve, and involve s.ecimen-cons.ming concerns. Here, we report a near-real-time automated cancer diagnos.s.workflow for breas. cancer that combines.dynamic full-field optical coherence tomography(D-FFOCT), a label-free optical imaging method, and deep learning for beds.de tumor diagnos.s.during s.rgery. To clas.ify the benign and malignant breas. tis.ues. we conducted a pros.ective cohort trial. In the modeling group(n = 182), D-FFOCT images.were captured from April 26 to June 20, 2018, encompas.ing 48 benign les.ons. 114 invas.ve ductal carcinoma(IDC), 10 invas.ve lobular carcinoma, 4 ductal carcinoma in s.tu(DCIs., and 6 rare tumors. Deep learning model was.built up and fine-tuned in 10,357 D-FFOCT patches. s.bs.quently, from June 22 to Augus. 17, 2018, independent tes.s.n = 42) were conducted on 10 benign les.ons. 29 IDC, 1 DCIs. and 2 rare tumors. The model yielded excellent performance, with an accuracy of 97.62%, s.ns.tivity of 96.88% and s.ecificity of 100%;only one IDC was.mis.las.ified. Meanwhile, the acquis.tion of the D-FFOCT images.was.non-des.ructive and did not require any tis.ue preparation or s.aining procedures. In the s.mulated intraoperative margin evaluation procedure, the time required for our novel workflow(approximately 3 min)was.s.gnificantly s.orter than that required for traditional procedures.approximately 30 min). Thes. findings.indicate that the combination of D-FFOCT and deep learning algorithms.can s.reamline intraoperative cancer diagnos.s.independently of traditional pathology laboratory procedures.
