Robotic assisted adrenalectomy: Is it ready for prime time?
Xin Ling Teo,Sey Kiat Lim 대한비뇨의학회 2016 Investigative and Clinical Urology Vol.57 No.-
Adrenal surgery is undergoing continuous evolution and minimally invasive surgery is increasingly being used for the surgical management of adrenal masses. With robotic-assisted surgery being a widely accepted surgical treatment for many urological conditions such as prostate carcinoma and renal cell carcinoma, the use of the robot has been expanded to include robotic-assisted adrenalectomy, offering an alternative minimally invasive platform for adrenal surgery. We performed a literature review on robotic-assisted adrenalectomy, reviewing the current surgical techniques and perioperative outcomes.

The primary objectives of this study were to experimentally investigate the shear characteristicsof the interface between an existing RC column and a reinforced concrete (RC) beam added to the existing RC column, and to propose a formula for estimating the shear capacity of the beam-column interface. The major test variables consisted of concrete strength, added steel reinforcement ratio and shear span to depth ratio. Failure characteristics, displacements at the loading point, slips of the beam-column interface, and shear capacities of the beam-column interface were analyzed. Test results indicate that both the shear capacity of the beam-column interface and the corresponding interfacial slip increased with a decrease in shear span to depth ratio. In addition, as concrete strength grew, the shear capacity of the beam-column interface increased, but the interfacial slip corresponding to the interfacial shear capacity remained almost unchanged. Moreover, both the shear capacity of the beam-column interface and the corresponding interfacial slip increased with an increase in the longitudinal steel reinforcement ratio of the added RC beam. A formula for predicting the shear capacity of the beam-column interface was developed. The test results validate the proposed formula and provide important guidance for the design of the RC beam added to the existing RC column.

Background: Acupuncture has been widely utilized for irritable bowel syndrome (IBS). However, heterogeneity is large among therapeutic strategies and protocols. The aim of this study was to propose some down-to-earth recommendations and establish an optimized protocol for acupuncture practice in IBS. Methods: A panel of 74 traditional Chinese medicine (TCM) acupuncturists participated in clinical issue investigation. Subsequently, systematic reviews concerning acupuncture for IBS were screened within 3 databases. An initial consensus questionnaire was formed from the results of clinical issue investigation and literature review. Ultimately, a Delphi vote was carried out to determine these issues. 30 authoritative experts with extensive experience were requested to respond with agreement, neutrality, or disagreement for the items. Consensus achievement on a given item was defined as greater than 80% agreement. Results: Following a 2-round Delphi survey, there were 19 items reaching consensus; of which 5 items (26.32%) achieved thorough consensus, and significant agreement was reached for the other 14 items. These items can be classified into the 3 major domains: 1) clinical outcomes that acupuncture can bring for favorable intervention population (5 items), 2) suitable therapeutic principles and parameters of acupuncture (13 items), 3) possible adverse events in the treatment (1 item). Conclusion: Without any ready-made guidelines and lacking of homogeneity in the published literatures, such expert consensus could be valuable for TCM acupuncturists in daily practice and patients with IBS to obtain appropriate and standardized acupuncture treatment. In addition, it also points out the clinical focus which need to be further explored in future trials.

Reclamation of closed dumping grounds is a potential solution to solve land scarce problems. Traditional geotechnical investigations of closed dumping grounds face some problems, such as the emission of hazardous liquids and gases, and the lack of ground information due to the discontinuity between two boreholes. Thus, noninvasive and continuous investigation methods are needed to supplement traditional geotechnical investigations. In this paper, two types of geophysical investigation methods, Seismic Analysis of Surface Waves (SASW) and 2D Resistivity, were carried out to study noninvasive and continuous site investigations for dumping grounds. The two geophysical methods are able to profile the distribution of physical properties of the fill and original materials, by which the extent of the dumping ground can be found and some anomalies in the subsurface can be located. Boreholes were used to assist in locating the dumping material-ground interfaces. The results show that dumping material-ground interfaces obtained from the two geophysical methods are roughly consistent. Moreover, attempt is made in the paper to use the geophysical methods to classify the types of dumping materials. The results show that the classification of dumping materials using the geophysical methods follows the results of the manual sorting of the dumping materials from a borehole.

Myogenic enhancer transcription factor 2c (MEF2c), one of the members of the MEF2 family of transcription factors, plays an important role in mammalian muscle development. However, the role of MEF2c in avian muscle development still remains unclear. To understand the function of MEF2c in avian muscle development, we first cloned the duck MEF2c coding domain sequence (CDS) and analyzed MEF2c expression in duck muscle tissues of embryos from 10 days of incubation to 1 week after birth using real-time PCR technology. The results showed that the duck MEF2c CDS consists of 1,398nucleotides that encode 465 amino acids. The MEF2c duck protein contains a MADS domain, a MEF2 domain and a HJURP_C domain with high homology to related proteins in other organisms. Different expression levels of MEF2c were found in skeletal, smooth and cardiac muscle. Therefore, these results indicated that duck MEF2c has two conserved domains (a MADS and a MEF2 domain), is an indispensable regulator of muscle development, and plays an important role in the development of duck muscle.

Zinc nger proteins (ZFPs) play important roles in plant responses to biotic and abiotic stresses. Through microarray analysis, an Oryza sativa L. multi-stress-responsive gene, OsMSR15, was identied and subsequently cloned from rice Pei’ai 64S (Oryza sativa L.). Expression of OsMSR15 was strongly up-regulated by cold, drought and heat stresses in different tissues at different developmental stages of rice. OsMSR15 contains two C2H2-type zinc nger motifs, a nuclear localization signal (B box), a Leu-rich domain (L-box) and a conserved EAR-motif close to its C-terminus. The OsMSR15-GFP fusion protein was localized to the nucleus. Yeast-one hybrid assay showed that OsMSR15 possesses transcriptional activation ability. Expression of OsMSR15 in Arabidopsis conferred drought tolerance, and transgenic plants showed hypersensitivity to exogenous ABA during the seed germination and post-germination stages. Transgenic plants also showed higher levels of free proline, less electrolyte leakage and increased expressions of a number of stress-responsive genes, including LEA3, RD29A, DREB1A and P5CS1 under drought stress. The obtained results indicate that OsMSR15 is an important regulator involved in plant response to drought stress.

Liver cancer is one of leading digestive malignancies with high morbidity and mortality. There is an urgent need for the development of novel therapies for this deadly disease. It has been proven that asparagus polysaccharide, one of the most active derivates from the traditional medicine asparagus, possesses notable antitumor properties. However, little is known about the efficacy of asparagus polysaccharide as an adjuvant for liver cancer chemotherapy. Herein, we reported that asparagus polysaccharide and its embolic agent form, asparagus gum, significantly inhibited liver tumor growth with transcatheter arterial chemoembolization (TACE) therapy in an orthotopic hepatocellular carcinoma (HCC) tumor model, while significantly inhibiting angiogenesis and promoting tumor cell apoptosis. Moreover, asparagine gelatinous possessed immunomodulatory functions and showed little toxicity to the host. These results highlight the chemotherapeutic potential of asparagus polysaccharide and warrant a future focus on development as novel chemotherapeutic agent for liver cancer TACE therapy.
