Authors: Pham Duong T. T.
Published: September 2021

Limnophila rugosa (Roth) Merr. is an annual herb native to wetlands in Vietnam. It is widely cultivated and used as food flavoring, seasoning or culinary herb. While most studies examine the essential oil of Limnophila rugosa, reports of cultivation practices such as substrates and spacing that may enhance the growth and yield of Limnophila rugosa is very limited. The objective of this study was to determine the appropriate thickness of the substrate and plant spacing for growth and yield of Limnophila rugosa under organic-oriented farming by using a completely randomized design (CRD) for the experiment. The results indicated that Limnophila rugosa performed the highest number of branches and plant fresh weight when it was grown at the substrate thickness of 20 cm in combination with spacing of 20 × 15 cm. However, the highest absolute yield (6,414.6 kg/1,000 m2) was obtained at a spacing of 20 × 10 cm combined with the substrate thickness of 20 cm.

Authors: Vo Binh T. T.
Published: September 2021

Asian bumblebee catfish (Pseudomystus siamensis) belongs to Bagridae family and is an economic value ornamental species. However, biological characteristics of this fish species have been rarely reported in the literature. A study to identify tolerant capacity to aquatic environment factors (incipient lethal temperature (ILT) and incipient lethal pH (ILpH) and oxygen threshold) of Asian bumblebee catfish at three developmental stages namely embryo, hatchling and ten-day post hatching (dph) was carried out from July 2018 to January 2019 at the Experimental Farm for Aquaculture of Fisheries Faculty - Nong Lam University in HCM City. The results showed that the incipient upper and lower lethal temperatures (IULT and ILLT) were 32.5oC and 22.3oC for embryos, 36.7oC and 18.7oC for hatchlings, and 38.6oC and 15.9oC for 10 dph fish, respectively. The incipient upper and lower lethal pHs (IULpH and ILLpH) were 10.7 and 4.4 for embryos, 10.2 and 3.7 for hatchlings, and 10.2 and 3.8 for 10 dph fish, respectively. The oxygen thresholds of the catfish at the three stages were 4.7, 1.1 and 1.0 mg O2/L, respectively. The Asian bumblebee catfish at post hatching stages appears to tolerate to unfavorable environmental factors compared to embryonic one. The study results would be an important scientific base for researches on seed production and conservation of the fish in the future.

Cloning, expressing and purification of recombinant C-terminal PMT of Pasteurella multocida
Authors: Vu Hung K.
Published: September 2021

Pasteurella multocida strains produce heat-stable toxin Pasteurella Multocida Toxin (PMT) which is the main virulence factor causing pasteurellosis in pigs. Therefore, PMT protein is considered as a promising candidate to study recombinant vaccine against pasteurellosis in pigs. In this study, we cloned the nucleotide sequence coding C-terminal fragment of PMT (tPMT-780), from acid amine 506 to acid amine 1285, into pRSET-A vector and expressed it on Escherichia coli BL21 bacteria. The SDS-PAGE result showed that tPMT-C780 was well-expressed by IPTG 1mM induction and determined to be insoluble protein, therefore it was purified by denaturation method using Ni-NTA beads. The protein elution samples contained only one protein band similar with the size of tPMT-C780 and positively reacted with PMT-specific antibody. These results suggested that we were successful in expressing and purifying C-terminal protein of PMT toxin, tPMT-C780. This is the primary material for further studies to produce recombinant vaccine against pasteurellosis in pigs.

Haemorrhoids are variceal Dilatation of anal and perianal venous plexus. Classically situated in the 3,7,11, o'clock position (left lateral, right posterior & right anterior respectively). Superior haemorrhoidal (vein) gives 2 branches on right side and 1
branch on left side. Hence, Piles are 2 on the right side and 1 on the left side. It was probably Buqrat (Hippocrates) (460 BC) who was the first to apply the name to the flow of blood from the veins of the anus. There is a detailed description of Bawaseer
in classical books authored by ancient Unani physicians. Haemorrhoids are one of the most common anorectal disorders with a reported prevalence of 4.4% up to 36.4% of the general population. The peak prevalence occurs between 45 and 65 years of
age. Anatomical classification of haemorrhoids includes internal and external haemorrhoids based on whether they are above or below the dentate line. Goligher's classification is the clinical staging of the prolapsing degree of internal haemorrhoids.
Risk factors for hemorrhoidal disease are conditions associated with increased intra-abdominal pressures such as pregnancy, obesity, constipation and straining during defecation and sitting for a long time on the toilet seat, and chronic cough. Principal
complaints of haemorrhoids include bleeding on defecation and prolapse of tissue. Haemorrhoid diagnosis involves taking a detailed history and conducting anorectal examinations (visual inspection, manipulation, digital examination, and anoscope.
Report of first recorded treatment for haemorrhoids comes from the Egyptian papyrus dated 1700 BC: “… Thou shouldest give a recipe, an ointment of great protection; Acacia leaves, ground, titurated and cooked together. Conservative treatment is used in “Everyday Lifestyle Guidance. Drug therapy for haemorrhoids is typically utilized for bleeding, pain, and swelling. Operative hemorrhoidectomies are reserved mainly for third- and fourth-degree haemorrhoids.
