Abstract
In the present work, we report on a theoretical-computational study of the growth mechanism of the TiO2-Graphene nanohybrid by atomic layer deposition. Hydroxyl groups (OH) are anchoring sites for interacting with the main ALD titanium precursors (Tetrakis (dimethylamino) Titanium, Titanium Tetrachloride, and Titanium Isopropoxide). Results demonstrate that the chemical nature of the precursor directly affects the reaction mechanism in each ALD growth step. Tetrakis(dimethylamino)titanium is the precursor that presents a higher affinity (lower energy barriers for the reaction) to hydroxylated graphene in the growth process. A complete reaction mechanism for each precursor was proposed. The differences between precursors were discussed through the non-covalent interactions index. Finally, the water molecules help reduce the energy barriers and consequently favor the formation of the TiO2-graphene nanohybrid.

Abstract
BACKGROUND Disseminated carcinomatosis of the bone marrow (DCBM) is a widespread metastasis with a hematologic disorder that is mainly caused by gastric cancer. Although it commonly occurs as a manifestation of recurrence long after curative treatment, the precise mechanism of relapse from dormant status remains unclear. Granulocyte colony-stimulating factor (G-CSF) can promote cancer progression and invasion in various cancers. However, the potential of G-CSF to trigger recurrence from a cured malignancy has not been reported.
CASE SUMMARY A 55-year-old Japanese woman was diagnosed with Ewing sarcoma localized on the fifth lumbar vertebrae 6 years after curative gastrectomy for T1 gastric cancer. After palliative surgery to release nerve compression, pathological diagnosis of the resected specimen was followed by curative radiation and chemotherapy. During treatment, G-CSF was administered 32 times for severe neutropenia prophylaxis. Eight months after completing definitive treatment, she complained of severe back pain and was diagnosed as multiple bone metastases with DCBM from gastric cancer. Despite palliative chemotherapy, she died of disseminated intravascular coagulation 13 d after the diagnosis. Immunohistochemical examination of the autopsied bone marrow confirmed a diffuse positive staining for the G-CSF receptor (G-CSFR) in the relapsed gastric cancer cell cytoplasm, whereas the primary lesion cancer cells showed negative staining for G-CSFR. In this case, G-CSF administration may have been the key trigger for the disseminated relapse of a dormant gastric cancer.
CONCLUSION When administering G-CSF to cancer survivors, recurrence of a preceding cancer should be monitored even after curative treatment.

Abstract
A 65-year-old man was referred to our hospital because of a fever and cough 19 years after chemoradiotherapy for small-cell lung cancer(SCLC)in the right middle lobe. Computed tomography(CT)revealed a normal right middle lobe, but found pneumonia and a tumor at the bronchial entrance of the right upper lobe. After treating the pneumonia with antibiotics and prednisolone, transbronchial biopsies(TBBs)revealed the tumor to be squamous cell carcinoma(SCC). Eight lines of chemotherapy including immune checkpoint inhibitors(ICIs)were completed with a 42-month survival following the initiation of chemotherapy for SCC, after which he ultimately died of hemoptysis. Survival of over 10 years from small- cell cancer is rare. We herein report the prognosis of SCLC and the treatment of subsequent primary lung cancer.

Abstract
To investigate the feasibility of utilizing electronically provided patient-reported outcomes(ePRO)to detect adverse events, we conducted a single-center prospective study targeting patients with advanced cancers who were receiving chemotherapy at our outpatient clinic. Participants were asked to respond to 71 relevant items from the PRO-CTCAE once a week for 8 consecutive weeks. An outpatient nurse evaluated the corresponding items on the CTCAE. Forty of 85 outpatients were enrolled. Thirty-four patients were excluded because of Bring Your Own Device(BYOD)restrictions and 11 were excluded for other reasons, including poor physical conditions. Those without BYOD were significantly older than the study participants(median age: 72 and 66 years, respectively)and were more likely to be male(65% and 35%, respectively). The overall response rate was 77%. The median number of symptoms per participant rated as ≥Grade 1 was 26(range: 0-48) by ePRO and 6(range: 1-15)by the nurse(p<0.01). Among the total number of symptoms detected by ePRO, the percentage of symptoms detected by both the nurse and ePRO was low(median: 4%, range: 0-67%). Symptoms detected consistently by both the nurse and ePRO were alopecia(67%), anorexia(38%), paresthesia(36%), diarrhea(28%), malaise(27%), oral mucositis(25%), constipation(24%), limb edema(24%), pain(22%), and dysgeusia(21%), suggesting that healthcare professionals tend to pay more attention to the symptoms that they think lead to intervention. Our findings indicate that the implementation of the ePRO system in outpatient care may help clinicians accurately recognize adverse events at earlier stages.

Abstract
INTRODUCTION Patients with unresectable or recurrent gastric cancer who have an objective response (OR) to nivolumab monotherapy are expected to have a good long-term prognosis. However, the OR rate for nivolumab treatment is low at 11%, and there is a need for biomarkers to predict the treatment response. This study aimed to analyze the significance of systemic inflammation-related variables and clinicopathologic characteristics as predictive markers of response to nivolumab monotherapy in patients with advanced gastric cancer. METHODS In this retrospective cohort study, we enrolled 71 consecutive patients who received nivolumab monotherapy for unresectable or recurrent gastric cancer. Receiver operating characteristic curve analysis was performed to determine the cutoff values of systemic inflammation-related variables, predictors of treatment response, and other prognostic factors related to nivolumab therapy. We focused on systemic inflammation-related variables measured before nivolumab induction and 2 weeks after its first administration and performed multivariate analysis to assess whether they could be used as prognostic factors. RESULTS Multivariate analysis revealed that a lymphocyte-to-monocyte ratio (LMR) of ≤3.28 after 2 weeks of initial nivolumab treatment (2wLMR) is a statistically significant predictor of treatment response (p = 0.012). The progression-free survival (PFS) rate of patients with liver metastasis was significantly worse than that of the other patients (1-year PFS: 0.0 vs. 24.4%, respectively; p = 0.005). The overall survival (OS) of patients with a low 2wLMR was significantly longer than that in patients with a high 2wLMR (1-year OS: 37.4 vs. 18.9%, respectively; p = 0.022). CONCLUSIONS Thus, the 2wLMR could be a useful biomarker to predict response to nivolumab treatment and the prognosis of unresectable and recurrent gastric cancer.

Abstract
Recent therapeutic advancements have prolonged the survival duration of patients with metastatic or recurrent colorectal cancer even during salvage treatment. Although treatment with regorafenib and trifluridine/tipiracil combination has exhibited apparent survival benefits, clear and objective evidence of a response to these drugs is scarce. Herein, the present study reports the case of a patient with rectal cancer refractory to multiple surgical interventions and standard chemotherapy. Treatment with regorafenib resulted in immediate improvement of respiratory failure caused by pulmonary lymphangitic carcinomatosis. This improvement persisted for over 3 months and was confirmed by radiology. Our findings suggest that regorafenib can reduce peritumoral edema via its interaction with the vascular endothelial growth factor receptor. Thus, regorafenib functions as a multityrosine kinase inhibitor to alleviate symptoms of lymphangitic carcinomatosis despite the low potency of the drug.

Abstract
BACKGROUND The gap between patients' and physicians' expectations from treatment has been a difficult problem in oncology because it affects decision-making. This study identified patients' expectations from their treatment and concerns when palliative chemotherapy was initiated. METHODS Patients completed a questionnaire, which included open-ended questions about their expectations from the treatment and their biggest concerns at that moment after a clear explanation that the nature of their metastatic or recurrent cancer treatment was palliative and not curative. One hundred and sixty-five consecutive Japanese patients were included in this study. RESULTS Twenty-nine percent of the patients described their expectation as "symptomatic improvement,"28% as"objective treatment effect,"and 19%as"cure."The most common concern was the toxicity(41%). No significant change was revealed in later-line treatment. CONCLUSION The patients' expectation from palliative chemotherapy and concerns should be considered more precisely in each phase. Dedicated palliative care and explanation of toxicity controlon the initiation of treatments are essential.

Abstract
In this opinion piece, we discuss how to place evolution in the context of origin-of-life research. Our discussion starts with a popular definition: 'life is a self-sustained chemical system capable of undergoing Darwinian evolution'. According to this definition, the origin of life is the same as the origin of evolution: evolution is the 'end' of the origin of life. This perspective, however, has a limitation, in that the ability of evolution in and of itself is insufficient to explain the origin of life as we know it, as indicated by Spiegelman's and Lincoln and Joyce's experiments. This limitation provokes a crucial question: What conditions are required for replicating systems to evolve into life? From this perspective, the origin of life includes the emergence of life through evolution: evolution is a 'means' of the origin of life. After reviewing Eigen's pioneering work on this question, we mention our ongoing work suggesting that a key condition might be conflicting multi-level evolution. Taken together, there are thus two questions regarding the origin of life: how evolution gets started, and how evolution produces life. Evolution is, therefore, at the centre of the origin of life, where the two lines of enquiry must meet.This article is part of the themed issue 'Reconceptualizing the origins of life'.

Abstract
At present, there is no set strategy for the treatment of patients with colorectal cancer subsequent to the failure of standard treatment, other than the use of regorafenib (RGR) and TAS-102. The best order in which to use these drugs, and their safety and efficacy in combination with other drugs, are currently under investigation. It has been reported that RGR has a resensitizing effect on tumors that have previously failed to respond to anticancer drugs; this makes it a promising salvage therapy for colorectal cancer. The present report describes the results of a retrospective study on 17 patients with metastatic colorectal cancer who received RGR treatment following the failure of standard therapy. Following RGR failure, 71% of the patients were fit for further anticancer treatment, and these patients survived longer than those who did not receive further treatment. Furthermore, this intervention did not shorten the period of best supportive care. As a considerable number patients were fit for further anticancer therapy after RGR treatment, which resulted in prolonged survival without shortening the period of best supportive care, it may be beneficial for future research to focus on finding the optimal time at which to switch from RGR to further anticancer therapy.

Abstract
BACKGROUND The fatigue strength of three peripheral suture techniques for flexor tendon repair was compared by cyclic loading of the repairs in the porcine flexor digitorum tendon. METHODS Thirty-six tendons were sutured using only peripheral sutures with 6-0 Nylon. An initial cyclic load of 10 N for 500 cycles was applied and increased by 10 N for an additional 500 cycles at each new load until rupture. RESULTS The fatigue strength of the symmetric running peripheral suture was 85.0% and 144.8% greater than that of the two kinds of the asymmetric running peripheral sutures. CONCLUSIONS Symmetric running sutures can enhance the suture strength and appears to be a useful technique for increasing the strength of the peripheral suture.

Abstract
We herein report an unusual case of Brodie's abscess of the radius in a child. A 13-year-old boy presented with pain on his right distal forearm. A plain radiograph showed an 8 cm translucent lesion in the distal radius. MRI showed a penumbra sign on the T1-weighted image, hyperintensity on T2-weighted images, and ring enhancement on the contrast-enhanced T1 image. 18F-FDG PET/CT images showed an uptake at the margin of the radius. Curettage and iliac cancellous bone grafting were undertaken for Brodie's abscess. Bacteriological examinations were found to be negative, however, the pathologic diagnosis showed chronic osteomyelitis. Eight months after surgery, the patient was asymptomatic and there was no sign of recurrence of infection. For Brodie's abscess in a child, thorough debridement is mandatory in addition to cancellous bone grafting. Brodie's abscess should be considered in the differential diagnosis of a patient who presents with forearm pain and exhibit the radiolucent osteolytic lesion on simple radiography.

Abstract
Gastrointestinal stromal tumors (GISTs) are the most common type of gastrointestinal mesenchymal tumors, although metastasis to the perigastric lymph nodes is relatively rare, compared with liver or peritoneal metastasis. In this report, we describe a case of stomach GIST with a solitary simultaneous metastasis in the left axillary lymph node. A 68-year-old man was diagnosed with a large upper-stomach GIST, and computed tomography and positron emission tomography revealed masses in the left axilla and right mediastinum. We did not detect evidence of metastases to the liver, or other sites including the perigastric lymph nodes, although findings from the surgically resected axillary lymph nodes were compatible with GIST metastasis. Treatment using imatinib markedly reduced the gastric and mediastinal lesions, and this response persisted for 3 years. The patient subsequently experienced rapid growth of the gastric lesion without mediastinal or axilla recurrence, which required palliative surgery. Despite continuing medical treatment (sunitinib and regorafenib), the patient died of liver metastases 23 mo after the surgery. Based on our findings, it appears that the axillary lymph nodes can be a potential metastatic site for GIST metastasis.

Abstract
Under cyclic loading, we recorded the fatigue strength of a six-strand tendon repair with different symmetry in the lengths of suture purchase in two stumps of 120 dental rolls and in 30 porcine tendons. First, the strengths of the repairs with 1, 2, 3, 4 and 5 mm asymmetry were screened using the dental rolls. The asymmetric core suture repairs were then made with a Kessler repair of equal suture purchase (10 mm) in two tendon stumps, and shifting two other Kessler repairs by 1, 3 or 5 mm, respectively, along the longitudinal axis of the tendon in relation to the first (symmetric) Kessler repair. The core repairs with 3 mm or more asymmetry in suture purchases in two tendon ends showed significantly greater fatigue strength and significantly smaller gaps compared with 1 mm asymmetry in core suture repair. Our results support that asymmetric placement of core sutures in two tendon ends favour resisting gapping at the repair site and 3 mm or more asymmetry is needed to produce such beneficial effects.

Abstract
A patient with hemangioendothelioma is described, who developed a metastatic pulmonary nodule, subsequently a bullous lesion contiguous to the nodule, and finally spontaneous pneumothorax. In such cases, newly formed bullous lesions may conceal originally visible metastatic foci and can be a potential source of spontaneous pneumothorax.

Abstract
One hundred and sixty-one patients with pulmonary metastases were studied with CT. Six of them proved to have endobronchial (intraluminal) metastatic lesions by bronchoscopy. Retrospective analysis of the CT studies showed obstruction and/or narrowing of the bronchi in 5 cases while no lesion was observed in one patient. Although CT can not always demonstrate intraluminal lesions, it should be performed when an endobronchial metastasis from extrathoracic malignancy is seen by bronchoscopy because it will show hilar or mediastinal lymphadenopathy, or single or multiple pulmonary metastases other than the endobronchial lesion.

Abstract
To determine the most appropriate radiographic approach to parotid tumors, computed tomography (CT) was performed in 65 patients with 33 benign tumors, 19 malignant tumors, 3 abscesses and 10 other lesions with a clinical appearance of tumor. In 22 of the 65 cases CT-sialography and in 26 ultrasonography (US) were also performed. The mass was well recognized on CT without sialography in all patients, and the lesion was also well evaluated in all those examined with US. At CT-sialography the tumor was well shown, but this method made it difficult to differentiate a benign from a malignant lesion, because the character of the delineation and the border of the tumor were difficult to evaluate. It is concluded that US and CT without sialography are satisfactory for evaluating the parotid tumor, and the indication for CT-sialography is limited to those cases in which the tumor is demonstrated on US, but is unclear on conventional CT.

Abstract
A 62-year-old man with a complaint of back pain lasting 2 months was admitted. He also presented a huge abdominal tumor. Diagnostic imaging showed metastatic tumors in the liver, lumbar vertebrae and bilateral lung. An ultrasound-guided needle biopsy revealed a lung tumor containing melanic tissue. Subsequently, there was an evident elevation in uric acid, phosphoric acid, potassium and lactate dehydrogenase concentrations in serum. Continuous hemodiafiltration and administration of rasburicase was initiated following the diagnosis of tumor lysis syndrome (TLS). However, he died on the fourth day owing to arrhythmia. An autopsy revealed metastatic deposits in the liver, lung, spine, ribs, and lymph nodes along the biliary system. Microscopic examinations revealed massive necrosis of normal hepatocytes and tumor cells with disseminated tumor thrombi in the portal system. The catastrophic progression of TLS appears to be influenced by a persistent portal blood flow deficiency by portal tumor thrombus in this case.

Abstract
OBJECTIVE This study aimed to evaluate the effects of a porcine acellular dermal matrix (PADM) with or without an enamel matrix derivative (EMD) on gingival recession defects treated with a coronally advanced flap (CAF) in dogs. MATERIALS AND METHODS Miller class II gingival recession defects (5 mm wide and 7 mm deep) were surgically created on the labial side of bilateral maxillary canines in 12 dogs. After 8 weeks of plaque accumulation, the 24 chronic defects were randomly assigned to one of the following 4 treatments: CAF, CAF with PADM (CAF/PADM), CAF with EMD (CAF/EMD), and CAF with EMD and PADM (CAF/EMD/PADM). The animals were sacrificed 10 weeks after surgery for histologic evaluation. RESULTS In all groups, root coverage was obtained to a varying degree. PADM was well incorporated in gingival connective tissue in the CAF/PADM and in the CAF/EMD/PADM groups. The height of newly formed bone was significantly greater in the CAF/EMD/PADM group than in the CAF and CAF/PADM groups. New cementum with periodontal ligament-like tissue was predominantly found in the CAF/EMD and CAF/EMD/PADM groups. The CAF/EMD/PADM group showed the greatest amount of new cementum among the groups examined, although the difference was not statistically significant. CONCLUSION Within the limitations of the present study, it can be concluded that CAF/EMD/PADM treatment may promote periodontal regeneration in gingival recession defects. CLINICAL RELEVANCE The present results suggest that the combination of EMD and PADM in conjunction with CAF may represent a promising approach for treating single Miller class II gingival recessions.

Abstract
Reversible computing has been studied since Rolf Landauer advanced the argument that has come to be known as Landauer's principle. This principle states that there is no minimum energy dissipation for logic operations in reversible computing, because it is not accompanied by reductions in information entropy. However, until now, no practical reversible logic gates have been demonstrated. One of the problems is that reversible logic gates must be built by using extremely energy-efficient logic devices. Another difficulty is that reversible logic gates must be both logically and physically reversible. Here we propose the first practical reversible logic gate using adiabatic superconducting devices and experimentally demonstrate the logical and physical reversibility of the gate. Additionally, we estimate the energy dissipation of the gate, and discuss the minimum energy dissipation required for reversible logic operations. It is expected that the results of this study will enable reversible computing to move from the theoretical stage into practical usage.

Abstract
OBJECTIVES Granulocyte-colony stimulating factor (G-CSF) has been shown to have combinatorial trophic effects with dental pulp stem cells for pulp regeneration. The aim of this investigation is to examine the effects of basic fibroblast growth factor (bFGF) in vitro and in vivo compared with those of G-CSF and to assess the potential utility of bFGF as an alternative to G-CSF for pulp regeneration. MATERIALS AND METHODS Five different types of cells were examined in the in vitro effects of bFGF on cell migration, proliferation, anti-apoptosis, neurite outgrowth, angiogenesis, and odontogenesis compared with those of G-CSF. The in vivo regenerative potential of pulp tissue including vasculogenesis and odontoblastic differentiation was also compared using an ectopic tooth transplantation model. RESULTS Basic fibroblast growth factor was similar to G-CSF in high migration, proliferation and anti-apoptotic effects and angiogenic and neurite outgrowth stimulatory activities in vitro. There was no significant difference between bFGF and G-CSF in the regenerative potential in vivo. CONCLUSIONS The potential utility of bFGF for pulp regeneration is demonstrated as a homing/migration factor similar to the influence of G-CSF.

Abstract
A 68-year-old man was admitted to our hospital after testing positive in a fecal occult blood test. He was subsequently diagnosed with advanced signet ring cell carcinoma of the appendix with disseminated peritoneal disease and ascites. Weekly chemotherapy with S-1 was commenced, and after three courses, the tumor shrunk in size and the ascites decreased. Two more courses were administered;however, disease progression was noted because of increasing ascites. The chemotherapy regimen was changed to weekly docetaxel, and after two courses, further tumor shrinkage and a decrease in ascites were noted. The disease course of this patient suggests that S-1 and docetaxel were effective against signet ring cell carcinoma of the appendix. Here we report this case and discuss the relevant literature.

Abstract
A 75-year-old man was found, by endoscopic examination, to have type 2 advanced gastric adenocarcinoma with esophageal invasion in the cardia. Endoscopy and other modalities revealed observable esophageal invasion. To minimize surgical intervention, we treated him with S-1 and cisplatin as neoadjuvant therapy. Treatment was as follows: S-1(80mg/m2)was administered orally for 3 weeks followed by 2 weeks of rest, and cisplatin(60mg/m2)was administered by intravenous drip on day 8. Two courses of treatment resulted in marked shrinkage of the primary lesion and improvement of the esophageal invasion. Total gastrectomy with splenectomy, and D2 lymph node dissection were performed with an adequately long proximal margin, without thoracotomy. Pathological efficacy was Grade 2. At present, 1 year after the operation, the patient presents no evidence of a recurrence. We concluded that through neoadjuvant chemotherapy for advanced gastric cancer with esophageal invasion, thoracotomy could be avoided, thereby reducing risks associated with surgery.

Abstract
Although similar patterns of phenotypic diversification are often observed in phylogenetically independent lineages, differences in the magnitude and direction of phenotypic divergence have been also observed among independent lineages, even when exposed to the same ecological gradients. The stickleback family is a good model with which to explore the ecological and genetic basis of parallel and nonparallel patterns of phenotypic evolution, because there are a variety of populations and species that are locally adapted to divergent environments. Although the patterns of phenotypic divergence as well as the genetic and ecological mechanisms have been well characterized in threespine sticklebacks, Gasterosteus aculeatus, we know little about the patterns of phenotypic diversification in other stickleback lineages. In eastern Hokkaido, Japan, there are three species of ninespine sticklebacks, Pungitius tymensis and the freshwater type and the brackish-water type of the P. pungitius-P. sinensis species complex. They utilize divergent habitats along coast-stream gradients of rivers. Here, we investigated genetic, ecological and phenotypic divergence among three species of Japanese ninespine sticklebacks. Divergence in trophic morphology and salinity tolerance occurred in the direction predicted by the patterns observed in threespine sticklebacks. However, the patterns of divergence in armour plate were different from those previously found in threespine sticklebacks. Furthermore, the genetic basis of plate variation may differ from that in threespine sticklebacks. Because threespine sticklebacks are well-established model for evolutionary research, the sympatric trio of ninespine sticklebacks will be an invaluable resource for ecological and genetic studies on both common and lineage-specific patterns of phenotypic diversification.

Abstract
BACKGROUND AND OBJECTIVE Although the application of EMD is a widely accepted periodontal-regenerative therapy, its effects on noncontained intrabony defects are unpredictable because of the lack of a space-making property. The combined use of EMD and autogenous bone grafts reportedly stimulates significant periodontal regeneration in intrabony defects. The aim of the present study was to evaluate the effects of EMD in combination with bone swaging (BS) and injectable calcium phosphate bone cement (CPC), which was placed into the spaces between the grafted swaged bone and the proximal host bone, on periodontal healing in one-wall intrabony defects in dogs. MATERIAL AND METHODS One-wall intrabony defects (3 mm wide and 5 mm deep) were surgically created on the mesial and distal sides of the bilateral mandibular premolars in four dogs. The 16 defects were assigned to one of the following treatments: EMD only, BS only, EMD with BS (EMD + BS), or EMD with BS and CPC (EMD + BS + CPC). The animals were killed 8 wk after surgery for histologic evaluation. RESULTS The height of newly formed bone was significantly greater in the EMD + BS + CPC group (3.73 ± 0.30 mm) than in the BS-only (2.74 ± 0.33 mm; p < 0.05) and EMD + BS (2.88 ± 0.98 mm; p < 0.05) groups. The area of newly formed bone was significantly larger in the EMD + BS + CPC group (5.68 ± 1.66 mm(2)) than in the EMD-only (3.68 ± 0.33 mm(2); p < 0.05), BS-only (3.48 ± 1.26 mm(2); p < 0.05) and EMD + BS (3.38 ± 1.37 mm(2); p < 0.05) groups. The EMD-only (4.63 ± 0.42 mm), EMD + BS (4.67 ± 0.30 mm) and EMD + BS + CPC (4.78 ± 0.54 mm) groups showed significantly greater cementum formation than did the BS-only group (3.93 ± 0.56 mm; p < 0.05). CONCLUSION These results indicate that treatment with EMD + BS + CPC promotes favorable periodontal healing in one-wall intrabony defects in dogs.

Abstract
The gap formation of five core plus peripheral suture techniques for flexor tendon repair was evaluated by cyclic load testing. Fifty pairs of dental roll tendon models were sutured using six-strand Pennington modified Kessler core suture with 4-0 Polypropylene. One-half or three-fourths circumferential interlocking cross-stitch, or three complete circumferential peripheral suture techniques were performed using 6-0 Polypropylene. An initial cyclic load of 10 N for 500 cycles was applied and increased by 5 N for an additional 500 cycles at each new load until rupture. The complete circumferential interlocking cross-stitch had the greatest fatigue strength. The partial circumferential cross-stitches resulted in significantly larger gap formations at both the repaired and unrepaired sides than the complete circumferential sutures, and were also associated with early rupture. The full circumference of the cut tendon must be sutured using an interlocking cross-stitch peripheral suture to improve strength and avoid gap formation.
