Abstract
Two oxygenated ergostane-type steroids including one new compound, 3β-hydroxy-5α,6β-methoxyergosta-7,22-dien-15-one (1) along with a known analogue ergosta-6,22-dien-3β,5α,8α-triol (2) were isolated from the crude extracts of the marine sponge-derived fungus Aspergillus sp. Their structures were elucidated on the basis of combined NMR and MS spectroscopic methods. Compound 1 was a marine ergostane-type steroid with two methoxy groups at C-5 and C-6, respectively. These oxygenated ergostane-type steroids were evaluated for their antibacterial activities against human or aquatic pathogens. Among them, compound 1 exhibited antibacterial activity against Staphylococcus aureus.

Abstract
In this study, a multicomponent reaction via the Mannich intermediate was developed using methanol, secondary amine, and sulfonamide as starting materials. This method uses methanol as a green C1 source. The substrate scope is wide, and the yield is good. The mechanistic study shows that methanol generates formaldehyde under electrochemical conditions, and sulfonyl amidine as a nucleophile reacts with Schiff base intermediates to form N-sulfonyl amidine in a single step.

Abstract
Traumatic scar is a disease that affected approximately tens of millions of patients worldwide. According to the histological and morphological properties of scars, the traumatic scar typically includes superficial scar, atrophic scar, hypertrophic scar, and keloid. Its formation is a natural consequence of wound healing, regardless of whether the wound was caused by trauma or surgery. However, the production of scars has considerable impacts on the physical and mental health of patients, even causing substantial aesthetic and functional impairments. Prevention or early treatment of scars is the most suitable therapeutic method, including surgical and non-surgical procedures; nevertheless, the benefits of non-operative therapies for scars are quite limited, and surgical treatments are always hard to achieve satisfying outcomes. Through the application of innovative technologies such as lasers, intense pulsed light, and radiofrequency, significant progress has been made in the treatment of traumatic scars. This review highlights the current advancements of photoelectric therapy for the prevention and treatment of various traumatic scars, which may throw light on innovative therapeutic options for scar therapies.

Abstract
Three ursolic acid-piperazine-dithiocarbamate ruthenium(II) polypyridyl complexes Ru1-Ru3 were designed and synthesized for evaluating antitumor activity. All the complexes exhibited high in vitro cytotoxicity against MGC-803, T24, HepG2, CNE2, MDA-MB-231, MCF-7, A549, and A549/DDP cell lines. Ru1, Ru2, and Ru3 were 11, 8 and 10 times, respectively, more active than cisplatin against A549/DDP. An in vivo study on MGC-803 xenograft mouse models demonstrated that representative Ru2 exhibited an effective inhibitory effect on tumor growth, showing stronger antitumor activity than cisplatin. Biological investigations suggested that Ru2 entered MGC-803 cells by a clathrin-mediated endocytic pathway, initially localizing in the lysosomes and subsequently escaping and localizing in the mitochondria. Mitochondrial swelling resulted in vacuolization, which induced vacuolation-associated cell death and necroptosis with the formation of necrosomes (RIP1-RIP3) and the uptake of propidium iodide. These results demonstrate that the potential of Ru2 as a chemotherapeutic agent to kill cancer cells via a dual mechanism represents an alternative way to eradicate apoptosis-resistant forms of cancer.

Abstract
Purpose: Burn is one of the most common injuries in clinical practice. The use of transcription factors (TFs) has been reported to reverse the epigenetic rewiring process and has great promise for skin regeneration. To better identify key TFs for skin reprogramming, we proposed a predictive system that conjoint analyzed gene expression data and regulatory network information. Methods: Firstly, the gene expression data in skin tissues were downloaded and the LIMMA package was used to identify differential-expressed genes (DEGs). Then three ways, including identification of TFs from the DEGs, enrichment analysis of TFs by a Fisher’s test, the direct and network-based influence degree analysis of TFs, were used to identify the key TFs related to skin regeneration. Finally, to obtain most comprehensive combination of TFs, the coverage extent of all the TFs were analyzed by Venn diagrams. Results: The top 30 TFs combinations with higher coverage were acquired. Especially, TFAP2A, ZEB1, and NFKB1 exerted greater regulatory influence on other DEGs in the local network and presented relatively higher degrees in the protein–protein interaction (PPI) networks. Conclusion: These TFs identification could give a deeper understanding of the molecular mechanism of cell trans-differentiation, and provide a reference for the skin regeneration and burn treatment.

Abstract
The present study investigated the key genes, which cause switch from adipogenic to osteogenic differentiation of human mesenchymal stem cells (hMSCs). The transcriptomic profile of hMSCs samples were collected from Array Express database. Differential expression network was constructed by calculating the Pearson's correlation coefficient and ranked according to their topological features. The top 5% genes with degree ≥2 were selected as ego genes. Following the KEGG pathway enrichment analysis and the relevant miRNAs prediction, the miRNA-mRNA-pathway networks were constructed by combining the miRNA-mRNA pairs and mRNA-pathway pairs together. In total, we obtained 84, 119, 94 and 97 ego-genes in B, BI, BT and BTI groups, and DLGAP5, DLGAP5, NUSAP1 and NDC80 were the ego-genes with the highest z-score of each group, respectively. Beginning from each ego-gene, we identified 2 significant ego-modules with gene size ≥4 in group BI, and the ego-genes were PBK and NCOA3, respectively. Through KEGG pathway analysis, we found that most of the pathways enriched by ego-genes were associated with gene replication and repair, and cell proliferation. According to the miRNA prediction results, we found that some of the predicted miRNAs have been validated to be the regulatory miRNAs of these corresponding mRNAs. Finally we constructed a miRNA-mRNA-pathway network by integrating the miRNA-mRNA and mRNA-pathway pairs together. The constructed network gives us a more comprehensive understanding of the mechanism of osteogenic differentiation of hMSCs.

Abstract
Four new platinum(ii) complexes, [Pt(Rut)(DMSO)Cl2] (Rut-Pt), [Pt(Try)(DMSO)Cl2] (Try-Pt), [Pt(ITry)(DMSO)Cl2] (ITry-Pt) and [Pt(BrTry)(DMSO)Cl2] (BrTry-Pt), with rutaecarpine (Rut), tryptanthrin (Try), 8-iodine-tryptanthrin (ITry) and 8-bromo-tryptanthrin (BrTry) as ligands were synthesized and fully characterized. In these complexes, the platinum(ii) adopts a four-coordinated square planar geometry. The inhibitory activity evaluated by the MTT assay showed that BrTry-Pt (IC50 = of 0.21 ± 0.25 μM) could inhibit the growth of T-24 tumor cells (human bladder cancer cell line) more so than the other three complexes. In addition, all of these Pt complexes exhibited low toxicity against non-cancerous HL-7702 cells. BrTry-Pt induced cell cycle arrest in the S phase, leading to the down-regulation of cyclin A and CDK2 proteins. BrTry-Pt acts as a telomerase inhibitor targeting the c-myc promoter. In addition, BrTry-Pt also caused mitochondrial dysfunction. Importantly, the in vitro anticancer activity of BrTry-Pt was higher than those of Rut-Pt, Try-Pt and ITry-Pt, and it was more selective for T-24 cells than for non-cancerous HL-7702 cells.

Abstract
STUDY OBJECTIVE To analyze indications for preoperative selection of patients with cystic adnexal masses to be treated by laparoscopic surgery. DESIGN Retrospective analysis (Canadian Task Force classification II-2). SETTING University and military hospitals. PATIENTS Three hundred sixteen women with adnexal masses. INTERVENTION Before laparoscopy, 214 patients underwent evaluation (size of adnexal mass, ultrasonographic image, CA 125, suspicious clinical diagnosis); in 102 women laparoscopies were performed without taking these factors into account. MEASUREMENTS AND MAIN RESULTS In the first center 99% of women were treated by laparoscopic surgery. One (0.4%) tumor of low malignant potential detected by deferred biopsy was operated on. In the second center 98% of cases were performed laparoscopically. In 3.9% of women carcinomas were detected intraoperatively and were treated by laparotomy (p = 0.04). CONCLUSION Laparoscopy is appropriate management of cystic adnexal masses, with a very low risk of unintentionally operating an ovarian carcinoma if a thorough preoperative evaluation is conducted. Only in centers where surgeons have enough training to cope with ovarian cancer may this evaluation be deferred, since conversion to laparotomy should be considered a second therapeutic step, and not an incorrect indication for laparoscopy. In centers where surgeons have no such training, strict preoperative selection of patients is mandatory

Abstract
Construction well divers in Taiwan reportedly suffer a high prevalence of dysbaric osteonecrosis. We studied five divers working at the same construction site. We recorded their diving methods, diving depths, bottom times, work patterns, water temperatures, and heart rates. We also monitored gas bubbles in the subclavian vein in selected dives. A crude but effective hot-water system protected divers against hypothermia and allowed them to work in 24 degrees-27 degrees C water. Divers worked approximately 6.6 h a day and progressed approximately 3.0 m a day while excavating an average of 148 buckets of sand and rock each weighing 49.5 kg. The divers sustained a heart rate increase of 49%. Sixty percent of their equivalent single dive bottom times exceeded the U.S. Navy's no-decompression limits. Two cases of venous bubbles were detected, and one of these divers showed symptoms of decompression sickness. The prolonged bottom time and lack of a decompression schedule probably contributed to a risk of decompression sickness and dysbaric osteonecrosis.

Abstract
In the above paper Chen et al. investigated the capability of uniformly approximating functions in C(Rn) by standard feedforward neural networks. They found that the boundedness condition on the sigmoidal function plays an essential role in the approximation, and conjectured that the boundedness of the sigmoidal function is a necessary and sufficient condition for the validity of the approximation theorem. However, we find that the conjecture is not correct, that is, the boundedness condition is not sufficient or necessary in C(Rn). Instead, boundedness and unequal limits at infinities conditions on the activation functions are sufficient, but not necessary in C(Rn).
