Bacillus is a diverse genus consisting of more than 200 species with extensive genetic diversity. Their beneficial effects in industrial shrimp farming have been well documented. However, little is known about the biodiversity of the Bacillus spp. in this aquaculture system. Taxonomic analysis by 16S rRNA sequencing does not always allow species-level identification of Bacillus spp. In this study, 26 Bacillus isolates from two industrial Litopenaeus vannamei shrimp ponds in Bac Lieu Province, Vietnam, were analyzed for their genetic diversity by multi-locus sequence typing (MLST). A total of 22 sequence types were identified and segregated into four distinct clusters, corresponding to B. subtilis, B. velezensis, B. siamensis, and B. licheniformis. Bacillus subtilis and B. velezensis accounted for more than 73% of the Bacillus isolates. Notably, the MLST scheme exhibited high discriminatory power and might be further simplified to be a convenient method to identify species of the genus Bacillus.
Mortality following transarterial embolization due to hemorrhage after liver venous deprivation
Thanh Dung Le,Van Sy Than,Minh Duc Nguyen,Hoai Linh Vu,Xuan Hai Dao,Hong Son Trinh 소화기인터벤션의학회 2022 Gastrointestinal Intervention Vol.11 No.2
Liver venous deprivation (LVD) is considered to be a safe and effective method that induces more rapid and important liver hypertrophy before major hepatectomy in comparison with portal vein embolization (PVE) alone. Bleeding complications after LVD or PVE are rare, but can be a life-threatening event. Herein, we report a case of perihepatic and extended subcapsular hematoma of the liver after LVD. Transarterial embolization was performed using gelfoam to control the hemorrhage; however, the patient developed irreversible liver failure and passed away after 38 days of treatment. In patients with LVD or PVE, severe post-procedural bleeding poses a substantial challenge for treatment. Arterial embolization should be carefully considered to avoid liver failure and even death, regardless of whether temporary embolization is used.

<P>A cooling system is an essential part of high-temperature superconducting (HTS) rotating machine manufacturing. Moreover, thermal behavior is a crucial parameter of the cooling system that shows unique characteristics of superconductivity below a specific temperature to maintain a superconducting state. Therefore, many experiments have been performed to investigate new reliable cryogenic cooling systems for a large-scale HTS rotating machine. The motivation for the study is our recent development of the cryogenic cooling system using thermal trigger switches; it effectively minimizes non-operational downtime of the HTS machine in cases of power supply or cryocooler failure. This paper focuses on two main targets. First, the thermal design of the cooling system for the 10 MW-class HTS rotating machine is enhanced. Second, the performance of the cooling system is observed for various cryogens to investigate the feasibility of using solid cryogen.</P>

The liver is the most frequently injured organ during abdominal trauma. Vascular injuries account for approximately 3% to 25% of all cases of liver trauma and are typically treated by transarterial embolization (TAE). We describe a case of American Association for the Surgery of Trauma grade V liver injury with a very large pseudoaneurysm and an arteriohepatic venous fistula (AHVF), which failed to respond to TAE. This case was successfully treated using a direct transhepatic glue injection without complications. AHVF is an exceedingly rare type of vascular injury in blunt trauma. Direct transhepatic glue injections could represent a reliable alternative to TAE for the treatment of visceral pseudoaneurysms, especially if TAE fails to eliminate the lesion.
Determinants of VietGAP Adoption by Tea Farmers in Phu Tho Province, Vietnam

Although the Vietnamese Ministry of Agriculture and Rural Development has issued a Good Agriculture Practice (VietGAP) procedure for tea production, the number of VietGAP-certified farmers still needs to grow. This research aimed to determine the determinants of VietGAP adoption in tea production in Thanh Ba District, one of the largest and highest tea production areas in Phu Tho Province. It applied a binary logit model to analyze data from 100 Vietnamese tea farmers. It found that age, tea revenue, access to credit, cooperative membership, and VietGAP training have a positive and statistically significant effect on encouraging the conversion decision of farmers. The study’s findings presented helpful information that the Vietnam Government may use insofar as how to apply and popularize VietGAP tea production to produce safer products, increase farmers’ income and protect the natural environment.

Right lumbar lymph trunk injury after right laparoscopic donor nephrectomy: a case report

Laparoscopic donor nephrectomy (LDN) is increasingly popular because of its advantages over open surgery. Chyle leak after donor nephrectomy is a rare but potentially lethal complication if not treated appropriately. We describe a case of a 43-year-old female patient with no remarkable history who presented a chyle leak on day 2 after right transperitoneal LDN. Since conservative treatment failed, the patient underwent magnetic resonance imaging (MRI) and intranodal lipiodol lymphangiography, which confirmed the chyle leak from the right lumbar lymph trunk into the right renal fossa. The chyle leak was percutaneously embolized twice, on postoperative day (POD) 5 and POD 10, by a mixture of N-butyl-2-cyanoacrylate and lipiodol. The drainage fluid decreased significantly after the second embolization. The subhepatic drainage tube was withdrawn on POD 14, and the patient was discharged on POD 17. MRI lymphangiography and intranodal lipiodol lymphangiography effectively identified the chyle leak point. Percutaneous embolization seems to be a safe, effective method for treating high-output chyle leaks.
