Rhabdomyosarcoma is the most common soft tissue sarcoma seen in childhood and adolescence. The most frequent sites are head and neck.

A young female with maxillary rhabdomyosarcoma involving region of maxillary sinus with skeletal metastases was primary treated acccording to RMS 2005 protocol. She received 9 cycles of chemotherapy. Primary tumor of maxillary sinus was surgicaly removed after 4 cycles of chemotherapy, with 6th cycle of chemotherapy a radical radiotherapy of primary tumor location and metastasis in spinal vertebras, ribs, pelvic bone and left femoral bone started what leads to complete regression of skeletal metastases. In course of maintenance therapy MRI scan showed 12 × 28 × 23 mm lesion in sacrum in the vicinity of right sacroiliacal joint with caracteristics of metastasis. Because the region of right sacroiliacal joint with bowel was already included in primary radiation treatment, tissue expander was laparoscopicaly inserted in lower pelvis to displace bowel loops from radiation field to prevent radiation enteritis. After external beam radiotherapy to her sacrum, a good response without any side effects was achieved.

Laparoscopic insertion of pelvic tissue expander prior EBRT and it's subsequent removal after EBRT is safe and effective method for displacing loops of bowel out of the pelvis. With minimal morbidity converts untreatable disease to treatable by allowing delivering high doses of radiation to the patient.

After 2 years of follow up the disease is in remission and the patient without any major complaint.

A one-stage anaerobic system in CSTR by inoculating activated sludge of simultaneous propionate degradation and methanogenesis was proposed to improve the high-solid digestion performance and to stabilize the reaction process. Semi-continuous mode was successfully used to perform HSAD from cellulosic ethanol whole stillage at an initial substrate loading of 15.4% (w/w) dry matter content with different OLRs from 1.5 to 5.0 gVS·L-1 d-1 at an HRT of 30 days. The average methane yield during whole digestion reached 349.9 mL⋅gVS-1 with a total VS removal rate of 61.3%. The acclimation mechanism of multifunctional activated sludge was also explored by analyzing the functional property, physiological activity and microbial community structure. The results indicated the feasibility and efficiency of multifunctional activated sludge in a semi-continuous high-solid stirred tank reactor system.The influence of copper ion (Cu2+) on anaerobic ammonium oxidation (anammox) performance and microbial community structures after oxytetracycline (OTC) stress recovery were assessed. Experimental results demonstrated that anammox performance were stressed by 1.0 mg L-1 Cu2+ and inhibitions were reversible with total nitrogen removal rate higher than 3.08 ± 0.2 kg N m-3 d-1. The residual OTC in the anammox sludge could combine with Cu2+ introduced and thereby retarded inhibition on performance in the presence of 2.0 mg L-1 Cu2+. Moreover, the positive relation of dominant bacterium Ca. Anammoxoglobus with the abundance of functional genes and parts of antibiotic resistance genes were observed, suggesting that regain of performance was the results of the gradual domestication of latent resistant species after inhibition. This investigation reveals new insights into resistance of anammox performance for Cu2+ and OTC.Zanthoxylum bungeanum meal (ZBM) is the by-product of Z. bungeanum seeds after pressing. It is restricted as a feed additive because it contains stimulating and potentially harmful substances, which are alkylamides and alkaloids. This study described the use of Lactobacillus paracasei and L. acidipiscis isolated from ZBM in solid-state fermentation of ZBM to reduce the concentration of undesirable alkylamides and alkaloids. By optimizing the substrate and fermentation conditions, the minimum contents of alkylamide and alkaloid were 2.96 and 3.20 mg/g, and the degradation rates reached 51.86% and 39.59%, respectively. Moreover, the biotransformation pathways of hydroxyl-α-sanshool and chelerythrine were established by identifying the metabolites. Bacterial diversity was shift significantly, and the relative abundance of Lactobacillus increased from 0.10% to 99.0% after fermentation. In conclusion, this study introduced a reliable strategy for processing ZBM as a feed additive.This study was aimed at developing a compound microbial agent to facilitate the composting of Chinese medicinal herbal residues (CMHRs). Different microbial agents were inoculated into a mixture of CMHRs, sheep manure, and biochar and composted for 42 days. The results demonstrated that the compound microbial agent (K1 + P1 + N4) inoculated in T1 can extend the thermophilic period during composting. Compared with control check (CK), the total nutrient contents of the vaccinated groups increased by 5.45-28.54%, and T1 had the highest value. The total organic carbon degradation rate and germination index of T1 were 1.95 and 1.03 times higher than those of the control. ABT-199 Moreover, significant increases in the abundance and diversity of the microbial community were also found in T1. Consequently, using K1 + P1 + N4 as a microbial agent for the composting of CMHRs is recommended, and this research provides a new idea to solve the problem of waste of CMHRs.Managing plastic waste remains an urgent environmental concern and switching to biodegradable plastics can reduce the dependence on depleting fossil fuels. This study emphasises the efficacy of macroalgae wastes, Eucheuma denticulatum residues (EDRs), as potential alternate feedstock to produce l-lactic acid (l-LA), the monomer of polylactic acid, through fermentation. An innovative environmental friendly strategy was explored in this study to develop a glucose platform from EDRs pretreatment with microwave-assisted autohydrolysis (MAA) applied to enhance enzymatic hydrolysis of EDRs. The results indicate that MAA pretreatment significantly increased the digestibility of EDRs during the enzymatic hydrolysis process. The optimum pretreatment conditions were 120 °C and 50 min, resulting in 96.5% of enzymatic digestibility after 48 h. The high l-LA yield of 98.6% was obtained using pretreated EDRs and supplemented with yeast extract. The energy analysis implies that MAA pretreatment could further improve the overall energy efficiency of the process.
