An experiment was conducted to determine the effects of caponization on the growth performance, breast and thigh muscles physical properties and fiber diameter of the Pectoralis major and Gastrocnemius pars externa in Taiwan country chicken cockerels. Caponized birds were surgically altered at 10 weeks of age. Birds were fed grower and finisher diets ad libitum during an eighteen-week experimental period. The results indicated that the live weight and feed intake in the capons were significantly (p<0.05) higher and the shank length was significantly (p<0.05) longer than in intact birds. There were no significant (p>0.05) differences in feed conversion and mortality between two treatments at 28 weeks of age. Compared with intact birds, the capons had greater (p<0.05) tenderness in the breast and thigh muscles. Cohesion of the breast muscle in the capons was significantly (p<0.05) better than in the intact birds, but the thigh muscles were not significantly (p>0.05) affected. No treatment differences (p>0.05) were associated with cooking loss, muscle chewiness, and elasticity. The capons had a significantly (p<0.05) smaller fiber diameter in the Pectoralis major, but were not significantly (p>0.05) different in the fiber diameter of the Gastrocnemius pars externa. It is concluded that castration did not depress growth compared with the intact birds, but did improve muscle tenderness. This difference was most pronounced in the thigh muscles.

Purpose: Using the implant for the breast reconstruction still remains the options, despite the breast reconstruction using autologous tissue is an ideal method. In this study, we used AlloDerm$^{(R)}$ to extend subpectoral pocket for covering implants to reduce implant related complications. Met hods : From January 2005 to June 2007, 18 breasts in 16 patients were reconstructed using implant and AlloDerm$^{(R)}$ immediately after mastectomy. Hospital records, database files, and clinical photographs were reviewed. A ten - point scale was used to evaluate the patient's satisfaction, with a range from 2(poor) to 10(excellent). Results: Mean age of the patients was 38.7 years at the time of operation. Mean weight of removed breast tissue was 287g. AlloDerm$^{(R)}$ was used to extend subpectoral coverage. Any systemic complication was not reported. Breast complication was developed in 4 cases. Implant removal or change was not experienced. Conclusion: Immediate breast reconstruction using Implant is useful methods for certain conditions, when donor tissue is insufficient and breast is non ptotic with round shape. In those cases, extension of muscle coverage using AlloDerm$^{(R)}$ could reduce complications and lead more acceptable results.

Thoracodorsal artery (TDA) flaps, ranging from the vascular-pedicled thoracodorsal artery perforator (TDAP) flap, the propeller TDAP flap, and the muscle-sparing latissimus dorsi (MSLD) flap to the conventional latissimus dorsi (LD) flap and the extended LD flap, can all be used for breast reconstruction. The aim of this paper and review is to share our experiences and recommendations for procedure selection when applying TDA-based flaps for breast reconstruction. We describe the different surgical techniques and our thoughts and experience regarding indications and selection between these procedures for individual patients who opt for breast reconstruction. We have performed 574 TDA flaps in 491 patients: 60 extended LD flaps, 122 conventional LD flaps, two MSLD flaps, 233 propeller TDAP flaps, 122 TDAP flaps, and 35 free contralateral TDAP flaps for stacked TDAP breast reconstruction. All the TDA flaps are important flaps for reconstruction of the breast. The LD flap is still an option, although we prefer flaps without muscle when possible. The vascular-pedicled TDAP flap is an option for experienced surgeons, and the propeller TDAP flap can be used in most reconstructive cases of the breast, although a secondary procedure is often necessary for correction of the pedicle bulk. The extended LD flap is an option for women with a substantial body mass index, although it is associated with the highest morbidity of all the TDA flaps. The MSLD flap can be used if the perforators are small or if dissection of the perforators is assessed to be hazardous.

This study evaluated the possible use of white muscle from cooked skipjack tuna as a constituent of diet foods. White muscles from the belly and dorsal area of cooked skipjack tuna were identified as anterior, median, and posterior. The skipjack tuna white muscle contained more moisture and ash (except for part I in both the belly and dorsal muscles) than chicken muscle, while it had less crude protein and crude lipid (except for part II in belly muscle). The yield was the highest in part I of both the dorsal and belly parts among the various parts of white muscles. The skipjack tuna white muscle contained 14-18% fewer calories than chicken breast muscle. Part I from both the belly and dorsal muscles had higher total amino acid contents than the other parts, but lower contents than chicken breast muscle. White muscle of skipjack tuna was rich in minerals, such as phosphorus, iron, and zinc. The total free amino acid content of part I in the belly and dorsal muscles was 1,152.1 and 1,215.7 mg/100 g, respectively, and was 1.7-1.8 times higher than in chicken breast muscle. The major amino acids in the white muscles from skipjack tuna were taurine, histidine, anserine, and carnosine. Based on these results, if it is possible to mask the fish odor, all parts of the white muscle from skipjack tuna could be used as constituents of diet foods.

Purpose: The purpose of this study was to analyze the effects of a combined exercise program on the level of physical fitness and fatigue for cancer survivors. Methods: The subjects were all of 61 persons consisted of prostate cancer(n=22), breast cancer (n=20), and stomach cancer(n=19) survivors. The exercise program was composed of a wall exercise, a chair exercise, a towel exercise and a bottle exercise which lasted 50-60 minutes each, two times a week for 12 weeks. The outcome measures were the fat mass, the muscle mass, the grip strength, the sit and reach, the 6 minutes walk, & fatigue. Results: At the completion of the 12-week combined exercise program, there were statistically significant differences in the grip strength, the sit & reach, the 6 minutes walk, & fatigue for the prostate, breast, and stomach cancer survivors. But no significant differences were found in the muscle mass between the pretest and posttest. Conclusion: As the 12-week combined exercise program was proved to be an effective intervention for improving muscle strength, flexibility, cardiopulmonary fitness & fatigue, it is thought that the program can be utilized as a rehabilitation program for cancer survivors.

We determined the effect of caponization on the carcass and giblet characteristics, and skin and muscle color in Taiwan country chicken cockerels. Caponized birds were surgically altered at 10 weeks old and were fed growing and finishing diets ad libitum during an eighteen-week experimental period. The results showed that the percentage of dressing, heart, feet, thigh, head and neck were significantly (p<0.05) higher in the intact birds, while the capons had a higher (p<0.05) percentage of abdominal fat, intestine, back, wing and breast. Eviscerated weight, breast width, gizzard, liver and spleen ratios were not affected by the treatments. The breast skin color values for lightness (L*) and yellowness (b*) values in the capons were significantly (p<0.05) higher than in the intact birds, but the thigh and back skin were not significantly（p>0.05）different. Compared with the intact birds, the capons had a significantly (p<0.05) less redness (a*) values in the back skin, but were not significantly (p>0.05) different in the breast and thigh skin. The L* value of the thigh muscle was significantly (p<0.05) greater in the capons than in the intact birds, but were not significantly (p>0.05) different in breast and back muscles. The b* values in the breast, back and thigh muscles of the capons were significantly (p<0.05) greater whereas the intact birds had a higher (p<0.05) a* values in the breast, back, and thigh muscles. Moreover, our findings also indicate that the castration resulted in a significant alteration in dressing percentage, carcass region and organ percentage.

Postmortem Proteolysis of breast (BM) and leg (LM) muscles in Chiayi native chickens at $5^{\circ}C$ were compared. Myofibrils were purified from BM and LM samples that were randomly taken from carcasses after 0, 1, 3, 7 and 14 days of storage at $5^{\circ}C$. Fragmentation of myofibrils were determined, and degradation of myofibrillar proteins were analyzed by the SDS-PAGE and western blots. The results showed that myofibril fragmentation index (MFI) was significantly (p<0.05) higher in BM than in LM samples. Disappearance of titin and nebulin and appearance of the 30 kDa component were more rapidly as seen on SDS-PAGE in BM than in LM samples. Western blots labeled with a monoclonal antibody to desmin also demonstrated that desmin degraded more quickly in BM samples. Our data suggested that postmortem proteolysis occurred more rapidly in breast muscles in Chiayi native chickens.

Breast deformity, in post-burn patients, is a common problem leading to lower self-esteem and reclusive behavior that impairs quality of life. The authors present the course of treatment of an 18-year-old immigrant girl who suffered second- to third-degree burns over approximately 20% of her total body surface area in her early childhood. The second- to third-degree burns were located on her right trunk and abdomen, as well as her right shoulder, neck, and right groin area. Since it was not offered in her home country, reconstructive surgery, including microsurgical breast reconstruction, was sought abroad. Due to the lack of available skin and soft tissue, a bilateral breast reconstruction with free transverse myocutaneous gracilis flaps was offered. This case illustrates one method of using microsurgery to address post-burn breast deformities in order to alleviate psychological suffering and improve quality of life.

The female breast is a potent symbol of maternity, sexuality, and feminity. Unfortunately, the frequency of breast cancer and mastectomy are increasing in Korea, so the reconstruction of breast becomes a important surgical procedure. The purpose of this study is to analyze the results of breast reconstruction using free TRAM flap and to suggest the operative techniques for more successful results. This study is based on a series of 39 cases of breast reconstruction using free TRAM flap in mastectomized patients. Among these cases, 21 patients underwent immediate reconstruction and 18 patients underwent delayed reconstruction. 2 patients underwent immediate bilateral reconstruction. The postoperative courses of these cases are uneventful. Breast reconstruction following mastectomy is one of the most challenging problems in plastic surgery. Nowadays the free TRAM flap is accepted as an excellent method of autogenous tissue breast reconstruction. We conclude that this technique has advantages as follows. The free TRAM flap has not associated with the complications of implant-based reconstruction. It provides sufficient volume for ptotic and natural breast, easily concealed donor site, and secondary aesthetic benefit of abdominoplasty. Unlike conventional pedicled TRAM flap, it has superiority in blood supply, and can make liberal setting of flap and sparing of rectus muscle. So it can provide more satisfaction about the final result of breast reconstruction.
