If this was the case, perhaps this could be succinctly mentioned. In consideration to their response #8, I understood and agreed with why half the seven of the 14 papers were discarded, but it did not provide much insight into why the Patterns of Biophilic Design were still used. A more useful example, which may have elucidated this more, was whether are there too few frameworks available, and/or none others could have been used.

The introduction can be optimized appropriately.The introduction of the term "Biophilia" can be more detailed and easy to understand .By contrast, the introduction of “Biophilic Design”is very substantial.It may be better to find some literature to combine workplace design and “Biophilic Design”,and then to explore the relationship between them.

The result of biophilic design frameworks for specific workplace typology is of certain value. The location of the workplace selected in this article is limited, the related biophilic factors are scientifically screened, and the researchers have made a detailed classification study. However, the huge research scope has certain obstacles to the relevant results, and the general and targeted conclusions will be worse.

Further references around the biophilic concept could also be provided, e.g.: Bjørn et al., 2009. The latter reference reviewed many international standards that advocate nature and biophilic design for view and building spaces, with examples given to the Singapore context.

P2, 47-53: Although in the past there were few guidelines, nowadays, there may be more standards that focus on nature integration within the built environment. WELL v2 has several features for Nature and Mind, and Biophilia – Parts I and II, with quantitative assessment methods provided. Similarly, the Green Mark system uses the green plot ratio, assigning credits to greenery provision to enhance biodiversity and visual relief. Other standards likely incorporate biophilic elements in building architecture and could be worth highlighting. The general issue raised by the authors do not necessarily imply a lack of guidelines for biophilic design, since there are several readily available, but may point toward prioritization or emphasis of criteria to meet certain varying expectations, which was alluded to on lines 52-53. If the authors agree with this, perhaps this could be revised here to reflect this.

P2, L63: Although I wouldn’t completely rule this out, POE surveys may not always provide feedback to the architect, since they are implemented post design-stage and the building would be operated by facility management or the owner. In my view, POE information had more utility diagnosing operation problems, which can be solved when running the building, identifying prominent sources of dissatisfaction that can prompt action to resolve these issues. Recently POE studies, also using office data, advocate this as benefit to their implementation, albeit not necessarily being the only reason: žGraham et al., 2020. Building & Cities.

P3, L106: While I generally agree with, questions could be raised to whether POE scales should be used to evaluate biophilic design evaluation. Biophilic design is known to elicit mental and physical health benefits, as stated by the authors on page 1, lines 29-32. Therefore, it would be more appropriate to use psychological scales (e.g., PANAS or psychological restoration), instead of design orientated question or survey. If the authors agree with this, this aspect could be revised.

Reading further to page 5, lines 189-192, the authors begin to suggest to this, but referred to them and others indoor environmental parameters as factors for the workplace. I would suggest better rationalizing the connections between the nine design parameters to biophilia to make these more overt.

when one reads it initially it would appear that there are many different modalities available for intraoperative imaging. However, the PET scan does not appear to have actually been used for intraoperative repeat imaging to assess resection, and fluoroscopy and 3D reconstructions using Brain Lab software are standard fare in many operating rooms. Intraoperative angiography might have been used in the case of vascular injury but this also is available in many institutions. The authors appear to really only use CT and MRI intraoperatively, with the other modalities imported preoperatively into the Brain Lab navigational system. 3D reconstructions of newly acquired data is a capability of the software, and is available in many places. Thus it would be helpful for the authors to clarify this. The AMIGO suite has great capabilities, but when it comes to intraoperative imaging, it is CT and MRI scans that are made, and then using Brain Lab and possibly other software, that information is processed and redisplayed including 3D reconstructions. Making this clear is important for others who either use the technique or who want to do so. All that is needed is easy intra-operative access to CT and MR imaging and the ability to import and reconstruct the data real time. That is plenty and a challenge for many, but the other imaging modalities used are either standard fare in many centers (x-ray imaging, endoscopy) or do not need to be in adjacent rooms (PET scanning and angiography (can be done in the primary Or). This does not detract from the value of the technique, but it is important to clarify that what really is happening is a variety of preoperative imaging is imported and co-registered into the Brain Lab, and then intraoperative MR and occasionally CT data is again obtained and processed and analyzed.

The authors argue that MACC1 expression did not significantly influenced cell proliferation in the two cell line models. However, cell proliferation was analyzed only in a 24-hour long period even though most cancer cells have a doubling time around 24 hours. In order to draw a conclusion about the proliferation effect a longer (48 or 72 hours) measurement is necessary.

This might be achieved by using the combination of so-called Tumor Treating fields (TTFields) with targeted drug, I have the following suggestions about this manuscript:

What is the rationale of using 150 kHz TTFields? TTFields at 100 kHz has also shown significant differences as cytotoxicity at p<0.01 and p<0.001 in HepG2 and Huh-7D12 cells which have around 60% and 50% of cell survival. Why did the authors use high frequency of TTFields though the cytotoxicity was also observed in lower dose (Fig 1A).

LC3 is increased in all the groups except in control tissue, however, cell death was increased only in combined group. How can the authors correlate autophagy with apoptosis? It is not so trustworthy that the only expression of LC3B indicate the treated condition have increased autophagy in the tumor tissue. Other important autophagy and degradation markers like Beclin1 and P62 need to be shown to reflect the regulatory mechanism of TTFields, as well as for the combined treatment with Sorafenib.

This is an interesting scientific study, as it concerns the issue of hepatocellular carcinoma, it also has a clinical aspect. The materials and methods section are elaborated in the details. Therefore, I expect further additional examination in the future. References contain mostly publications printed in the last 10 years. The authors indicated that TTFields had potential to be a new treatment option of hepatocellular carcinoma. The present study was examined in terms of autophagy and apoptosis in the antitumor effects of TTFields and sorafenib. However, the exact mechanism of the combination therapy induced cell death is not yet known as the activation of autophagy in the combination therapy was not increased.

In vitro experiments sub-section in Methods sections lacks many experimental details (e.g., type of plate/flask, plating overnight or not before experiment, number of plated cells). A very important missing is not showing the actual number of rats included in the final analyses (the ones who successfully received therapy for more than 18 hours/day). This must be added.

Another puzzling experiment is the schedule for the in vivo work. Since the authors missed to add Figure 4A for timeline, based on Methods section the rats were treated for 5 days with TTFields and or sorafenib and a day later the rays were sacrificed. While a short “acute” follow-up is welcome the most important experiment should allow the follow-up for much more days to indeed observe the effect of TTFields added to sorafenib. I could not find an explanation for not including a long term follow-up. In my opinion, this is a key therapeutically experiment which must be done and included in the study.
