Abstract
This paper reports a multi-throughput multi-organ-on-a-chip system formed on a pneumatic pressure-driven medium circulation platform with a microplate-sized format as a novel type of microphysiological system. The pneumatic pressure-driven platform enabled parallelized multi-organ experiments (i.e. simultaneous operation of multiple multi-organ culture units) and pipette-friendly liquid handling for various conventional cell culture experiments, including cell seeding, medium change, live/dead staining, cell growth analysis, gene expression analysis of collected cells, and liquid chromatography-mass spectrometry analysis of chemical compounds in the culture medium. An eight-throughput two-organ system and a four-throughput four-organ system were constructed on a common platform, with different microfluidic plates. The two-organ system, composed of liver and cancer models, was used to demonstrate the effect of an anticancer prodrug, capecitabine (CAP), whose metabolite 5-fluorouracil (5-FU) after metabolism by HepaRG hepatic cells inhibited the proliferation of HCT-116 cancer cells. The four-organ system, composed of intestine, liver, cancer, and connective tissue models, was used to demonstrate evaluation of the effects of 5-FU and two prodrugs of 5-FU (CAP and tegafur) on multiple organ models, including cancer and connective tissue.

Abstract
Previously, live offspring have been produced from porcine oocytes vitrified at the immature stage (Somfai et al. 2014 PLoS One 9, e97731); however, their embryo developmental rates remain low. The aim of our current research was to test the effects of resveratrol, an antioxidant and anti-apoptotic agent on the developmental competence of immature vitrified oocytes during in vitro maturation (IVM) after warming. Follicular porcine cumulus-oocyte complexes (COC) were vitrified on Cryotop® sheets (Kitazato Corp. Shizuoka, Japan) using the cryoprotectant treatment and warming method of Somfai et al. (2015 J. Reprod. Dev. 61, 571–579). After warming, the oocytes were subjected to IVM for 46 h in a chemically defined porcine oocyte medium (POM) enriched with 10 ng mL−1 epidermal growth factor, 10 IU mL−1 eCG, and 10 IU mL−1 hCG. During the first 22 h of IVM, the medium was supplemented with 1 mM dibutyryl cAMP. The following 24 h of IVM was performed in POM without dibutyryl cAMP. Vitrified/warmed COC (vitrified group) and freshly collected COC (control group) were matured either in the absence or presence of 2 µM resveratrol (RES− and RES+, respectively) throughout the entire IVM. At the end of IVM, oocytes were denuded and their survival was evaluated. Then, those with 1 polar body (PB1+) were selected for parthenogenetic activation (Day 0). Activated oocytes were cultured for 7 days in PZM-3. Survival, nuclear maturation, cleavage, and blastocyst rates were assessed. The experiment was replicated 5 times. Results were analysed by one-way ANOVA and Tukey’s multiple comparison test. Vitrification reduced the percentage of live oocytes after IVM both in RES− and RES+ groups in a similar manner (47.9 and 51.8%, respectively) compared with control RES− and RES+ groups (99.4 and 100%, respectively; P < 0.05) There was no statistical difference among groups in the percentage of PB1+ oocytes (ranging between 76.1 and 90.2%). On Day 2, the cleavage rate in vitrified RES− group was lower than those in control RES− and RES+ groups (55.9 v. 78.5% and 79.2%, respectively) whereas the vitrified RES+ group did not differ from the others (72.1%). The blastocyst developmental rate calculated from total cultured oocytes on Day 7 in vitrified RES+ group was significantly higher (P < 0.05) than that in the vitrified RES− group (26.2% v. 6.9%, respectively) and did not differ significantly from those of control RES− and RES+ groups (32.1 and 36.0%, respectively). Blastocyst rates in control RES− and RES+ groups were significantly higher (P < 0.05) than that in vitrified RES− group but did not differ from one another. In conclusion, supplementation of IVM medium with resveratrol improved the developmental competence of vitrified, but not freshly collected oocytes.

Abstract
Although offspring have been produced from porcine cumulus-oocyte complexes (COC) vitrified at the immature stage (Somfai et al. 2014 PLoS One 9, e97731), embryo development rates have remained low. Numerous vitrification protocols are reported with a wide variation in the applied exposure time to the vitrification solution. Because cryoprotectants in the vitrification solution can be detrimental to the oocytes and their subsequent development, it is important to verify the effect of their exposure time to the COC. In this study, we compared the development of a control group with 3 toxicity control (TC) groups in which COC were exposed to the vitrification solution for 30 s, 1 min, or 1.5 min (TC1, TC2, and TC3, respectively) at 38.5°C. Before exposure, the COC were rinsed and equilibrated in 7 µg mL−1 cytochalasin B. The equilibration solution consisted of 2% (vol/vol) ethylene glycol + 2% (vol/vol) propylene glycol and the vitrification solution contained 17.5% (vol/vol) ethylene glycol + 17.5% (vol/vol) propylene glycol, 50 mg mL−1 polyvinylpyrrolidone and 0.3 M sucrose. The COC were not exposed to liquid nitrogen. After washing in a warming solution of 0.4 M sucrose at 42°C, COC were washed in a sucrose gradient from 0.2 to 0.0 M. Subsequently, the COC were subjected to in vitro maturation in porcine oocyte medium. During the first 20 h of in vitro maturation, the porcine oocyte medium was supplemented with 10 IU mL−1 eCG, 10 IU mL−1 hCG, 1 mM dibutyryl cAMP, and 10 ng mL−1 epidermal growth factor. Then, the medium was replaced with dibutyryl cAMP-free porcine oocyte medium for an additional 28 h. After in vitro maturation, oocytes were parthenogenetically activated (Day 0) and cultured for 7 days in porcine zygote medium. Survival, nuclear maturation, cleavage, and blastocysts rates (Days 6 and 7) were assessed. All parameters were statistically analysed by binary logistic regression. Only the survival rate of TC3 was significantly lower than that of the control group (89.2 v. 95.6%). Exposure to cryoprotectants significantly decreased maturation rates in TC1, TC2, and TC3 compared with the control (72.6%, 75.2%, 76.3% v. 86.1%). Cleavage rates were significantly lower in TC2 and TC3 than that in the control (82.8% and 81.7% v. 92.9%). Concerning blastocyst rates on Day 6 and Day 7 of in vitro culture, only TC1 could reach the same level as the control, expressed on the total number of activated oocytes (54.6% v. 67.7%, and 64.0% v. 72.9%, respectively) as well as expressed on the cleaved oocytes (61.4% v. 72.4% and 72.0% v. 78.0%, respectively). Consequently, despite the reduced maturation rate, TC1 provides the same quantity of blastocysts from matured oocytes as the control. In conclusion, exposure to the vitrification solution for longer than 30 s has toxic effects on COC and therefore is not recommended for vitrification.

Abstract
OBJECTIVE Lymphoedema of the extremities is a widespread pathological condition that mostly occurs as a complication of cancer resections, especially in women. Conventional therapy refers to conservative and physiotherapeutic approaches. Surgical strategies have been widely reported in the literature and are still challenging. Part of this literature focuses on the supra microsurgical lymphaticovenular anastomosis (LVA) technique. LVA is characterized by a high success rate, minimal invasivity and broad indications. Furthermore, this procedure can be performed under local anesthesia. PATIENTS AND METHODS From October 2011 through October 2014, 69 patients affected by lymphedema underwent LVA surgery in Siena University Hospital, Italy. Preoperative and postoperative evaluations were taken. RESULTS Totally, 366 anastomosis have been performed. The average rate was 5.3 anastomosis per patient. All patients registered a decrease in the size of the affected side. The average volume reduction was 50%. Patients also showed a reduction of lymphangitis episodes and reduction of compression garments class. Moreover, a satisfaction index was evaluated. The majority of patients (72.5%) was extremely satisfied of the surgery. CONCLUSIONS LVA has demonstrated to be an effective surgical strategy to treat lymphoedema, especially in secondary cases in early stages. Although LVA is widely discussed in the literature, the majority of works relates to Japanese authors and few reports exist outside Japan. This paper represents the very first retrospective analysis of the adoption of LVA technique in Italy and one of the few outside Japan.

Abstract
The need for superior vena cava (SVC) or inferior vena cava (IVC) recon struction is not uncommon: lung cancer, mediastinal tumors, or retroperitoneal neoplasms are the most frequent indications for caval replacement. Since auto genous veins, which represent the most satisfactory venous substitute, have not been applicable to caval replacement, because of the lack of suitable length and caliber, many types of materials have been tested in the venous system. The present study was planned to compare the potential of expanded polytetrafluoroethylene (e-PTFE) and glutaraldehyde-tanned human umbilical vein (HUV) grafts as caval substitutes. Patch (4 x 5 cm) reconstruction of the SVC was carried out in 10 dogs, tubu lar (3 x 10 mm) reconstruction of the SVC in 5 dogs, and patch (1 x 2 cm) recon struction of the IVC in 8 dogs. In the patch reconstruction groups, HUV grafts were used in half of the cases and 30 μm pore sizes e-PTFE grafts in the other half, while in the tubular SVC replacement group, only e-PTFE grafts were employed. The grafts were removed fifteen to thirty days after IVC patch re construction, thirty to two hundred seventy days after SVC patch reconstruc tion, and thirty-three to forty-one months after SVC tubular replacement. In every instance, specimens were obtained for light microscopy (LM) and scan ning electron microscopy (SEM). HUV patches implanted in the SVC showed hemorrhagic foci at their central portion and marked constriction at the anastomotic regions. On the contrary, the inner surface of e-PTFE patch grafts was covered with a uniform and glis tening neointima. By LM, e-PTFE patches showed a smooth and regular lumi nal surface, while the inner surface of HUV patches was irregular, with hemorrhagic areas in the underlying layers. By SEM, e-PTFE patches revealed a more rapid and orderly endothelialization of their inner surface than HUV patches did. Tubular SVC reconstruction showed the good long-term viability of the e-PTFE neointima (as long as forty-one months after grafting). Only spotty areas revealed neointima alterations, such as fibrinoid degeneration, fo cal necrosis, or minor thrombotic foci. In the IVC patch reconstruction model, HUV grafts showed an exuberant fibrin deposition on their inner surface and delayed endothelialization patterns, as compared with e-PTFE grafts. Since rapid healing with rapid endothelialization is accepted as the most important factor providing the graft luminal surface with the best antithrombotic proper ties, the present study demonstrated that e-PTFE is a more suitable material than HUV for SVC and IVC reconstruction.

Abstract
Zebrafish possess a remarkable capacity for cardiac regeneration throughout their lifetime, providing a model for investigating endogenous cellular and molecular mechanisms regulating myocardial regeneration. By contrast, adult mammals have an extremely limited capacity for cardiac regeneration, contributing to mortality and morbidity from cardiac diseases such as myocardial infarction and heart failure. However, the viewpoint of the mammalian heart as a postmitotic organ was recently revised based on findings that the mammalian heart contains multiple undifferentiated cell types with cardiogenic potential as well as a robust regenerative capacity during a short period early in life. Although it occurs at an extremely low level, continuous cardiomyocyte turnover has been detected in adult mouse and human hearts, which could potentially be enhanced to restore lost myocardium in damaged human hearts. This review summarizes and discusses recent advances in the understanding of endogenous mechanisms of cardiac regeneration.

Abstract
Patients with breast cancer-related lymphedema (BCRL) need a life-long self-care program that they can adhere to enable them to manage their lymphedema. The objective of this study was to assess the effectiveness of a holistic BCRL self-care program that patients could easily adhere to and comply with. A prospective, longitudinal, comparative study between affected arms and unaffected arms in unilateral breast cancer patients was implemented over a six-month period. Both the lymphedematous and unaffected arms of 23 patients with unilateral BCRL were followed and measured. The daily 10-minute holistic BCRL self-care program consisted of modified Japanese rajio taiso (Japanese radio calisthenics), a gentle arm exercise combined with deep breathing, skin moisturizing care using a traditional lymphatic drainage technique, and basic self-care education. Arm and edema volume, relative volume change, resistance of the skin to compression (fibrosis), lymphedema-related symptoms, skin condition, and self-care were assessed. At the end of six-months the volume of all limb segments and resistance of the tissues to compression at all measurement points of the affected arm were significantly reduced. On the unaffected side, only the volume of the forearm and the whole arm was significantly reduced and fibrosis significantly reduced only in the forearm. There was no significant difference in edema volume and relative volume change. Lymphedema-related symptoms significantly improved. Perceived adherence, effectiveness, burden, score and average time for self-care significantly increased. Our results demonstrate that this 10-minute self-care program may improve BCRL and its self-care.

Abstract
BACKGROUND Many users in Japan of skin brightening/lightening cosmetics containing rhododendrol (RD) have developed leucoderma. Leucoderma appears on skin areas repeatedly treated with RD-containing cosmetics. RD-induced leucoderma (RDIL) presents different degrees of well-defined hypopigmentation. It is crucial to determine the degree of hypopigmentation to differentiate RDIL from vitiligo vulgaris (VV). OBJECTIVES To quantitatively evaluate hypopigmentation of RDIL lesions and the recovery of pigmentation, and to compare the hypopigmentation with VV and normal skin. MATERIALS AND METHODS Sixteen cases of RDIL, nine cases of VV and 15 healthy controls were examined using a novel multispectral camera (MSC) that can simultaneously obtain the reflection intensity at 10-nm wavelength intervals from 400 to 760 nm of the photographed area. ∆Absorbance was calculated by subtracting the log of reflection intensity of the target area from that of a white reflection standard. RESULTS Most RDIL lesions showed lower ∆Absorbance than healthy skin and higher ∆Absorbance than VV lesions between 400 and 550 nm. Statistical comparison of the maximum ∆Absorbance from 420 to 460 nm (Max∆Absorbance) for VV, RDIL and control skin showed that the Max∆Absorbance of RDIL was significantly higher than that of VV and lower than that of control skin. The comparison of ∆Absorbance of the same sites in RDIL lesions between the initial visit and 6 months later showed significant improvement after 6 months. CONCLUSIONS These studies demonstrated quantitative changes in RDIL and its recovery phase and suggested the utility of a MSC in obtaining objective colour information of skin disorders.

Abstract
Twelve high schools in Japan (of which six are in Fukushima Prefecture), four in France, eight in Poland and two in Belarus cooperated in the measurement and comparison of individual external doses in 2014. In total 216 high-school students and teachers participated in the study. Each participant wore an electronic personal dosimeter 'D-shuttle' for two weeks, and kept a journal of his/her whereabouts and activities. The distributions of annual external doses estimated for each region overlap with each other, demonstrating that the personal external individual doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual doses due to the terrestrial background radiation level of other regions/countries.
