A retrospective study on 40 cases of digestive tumor diagnosed by combination of ultrasound, X-ray and laparoscopy in which the ultrasound and anapathology play a role as screen has shown that the sensitivity and accuracy of ultrasound in the detection of digestive tumors was 97.05% and 87.50%, respectively. However, it should combine the ultrasound with other imaging diagnosis to obtain the higher accuracy

Ultrasound (US) is a good screening modality to confirm or exclude aneurysm, especially abdominal aortic aneurysm (AAA). Transesophageal echocardiography (TEE) provides information for thoracic aneurysm except in the area of proximal (blind spot). In HCM, ultrasound and colour Doppler US in 10 years (1986-1987) are still the best screening modality of imaging diagnosis for detecting aortic aneurysm in preclinical stage, play a significant role in modifying the patient's prognosis.

55 cases of amoebic hepatic abscess diagnosed basing on the clinic, ultrasound B-mode and Doppler in 1998 in Hå ChÝ Minh medical center. The duration of disease was 6-10 days. Of which 10 cases were monitored continuously until the disease free. There was no specific image of amebic hepatic abscess on the ultrasound. Most of abscess focused in the right liver. The size of abscess was reduced gradually as duration of the treatment. The conclusion: the ultrasound helps the needle aspiration of the complicated diseases and monitors the response of the treatment.

The ultrasound images of the amoebic hepatic abscess during the internal treatment were studied to evaluate the disease's progress and the response to the available guideline of treatment. The ultrasound's features and the distribution of the abscess focuses in 55 patients with the amoebic hepatic abscess during the treatment (6 months - 10 years) were evaluated. The conclusion: the diagnosis should base on the ultrasound, clinical features and needle aspiration as the guidance of the ultrasound.

Ultrasound cross-sectional prospective investigation on 16 patients with Dengue fever, showed that 15/16 cases, gall bladder wall thickness was a factor of prognosis, standard for patients with high risk of volume dropping shock related to kidney syndrome, 12/16 cases with abdominal cavity fluid, 7/16 cases there was perirenal collection of fluid, 3/16 cases of fluid subcapsular collection in the liver, pleural effusion. In addition, there may be large pancreas and spontaneous rupture of the kidney.

In this study, twenty-five yeast strains were isolated from soil samples collected in the gold mining ore in Gia Lai, Vietnam. Among them, one isolate named GL1 T could highly tolerate Cu 2+ up to 10 mM, and the isolates could also grow in a wide range of pH (3–7), and tem perature (10–40 ℃). Dried biomass of GL1 was able to remove Cu 2+ effectively up to 90.49% with a maximal biosorption capacity of 18.1 mg/g at pH 6, temperature 30 ℃, and incuba tion time 60 min. Sequence analysis of rDNA indicated this strain was closely related to Rhodotorula mucilaginosa but with 1.53 and 3.46% nucleotide differences in the D1/D2 domain of the 28S rRNA gene and the ITS1-5.8S rRNA gene-ITS2 region sequence, respect ively. Based on phylogenetic tree analysis and the biochemical characteristics, the strain appears to be a novel Rhodotorula species, and the name Rhodotorula aurum sp. nov. is pro posed. This study provides us with more information about heavy metal-tolerant yeasts and it may produce a new tool for environmental control and metal recovery operations.

Artichoke (Cynara scolymus L.) is a perennial plant belonging to the Asteraceae family originating from the Mediterranean region. In Vietnam, there are some varieties of artichoke which are extensively cultivated and propagated in highland areas, however, there have been limited detailed scientific publications on the chemical composition and biological activity of artichoke grown in Vietnam. Therefore, this study provides a detailed description of the extraction, isolation, and structural determination of 20 natural secondary metabolites present in harvested artichoke. The antioxidant activity of the extract and the 9 isolated compounds are tested in 1,1-diphenyl-2-picrylhydrazyl radical scavenging and ex vivo malondialdehyde model. Among the selected compounds, 1-caffeoylquinic acid, 3-caffeoylquinic acid, chlorogenic acid, 4-caffeoylquinic acid, cynarin, 1,5-dicaffeoylquinic acid, 4,5-di-caffeoylquinic acid, cynaroside, and scolymoside exhibited strong radical scavenging activity with IC50 values ranging from 5.7 to 61.6 µM. In the malondialdehyde assay, 1,3-dicaffeoylquinic acid (or cynarin) showed the strongest activity with an IC50 value of 24.7 µM, followed by 1,5-di-caffeoylquinic acid (66.8 µM), and 4,5-di-caffeoylquinic acid (127.3 µM). This outcome contributes to establishing a database on the phytochemical and antioxidant activity of the Vietnamese artichoke.

Objective: To investigate the antitumor effect of maesopsin 4-O-β-glucoside (TAT2) isolated from the leaves of Artocarpus tonkinensis (A. tonkinensis) A. Chev. ex Gagnep. Methods: The antitumor activity of TAT2 was evaluated in Lewis lung carcinoma (LLC) tumor-bearing mice. BALB/c mice had tumors induced by implantation with 2 × 10

Background: Hypertension is a common disease in adults, also the leading cause of cardiovascular disease and premature death worldwide. The prevalence of hypertension has increased, especially in low- and middle-income countries. Therefore, hypertension screening is important to provide the basis and evidence for the development of timely intervention policies and programs. The objective of the “May Measurement Month” 2022 program is to investigate the prevalence of hypertension, drug treatment and blood pressure control in people in Thua Thien Hue province and to assess the risk factors surrounding hypertension. Subjects and Methods: This cross–sectional study collected data from volunteer adults (≥ 18 years old) in Thua Thien Hue province from 7/2022 to 8/2022. Sitting blood pressure had been measured in triplicate according to standardized specified methods of the International Society of Hypertension. Results: Average age 54.07 ± 18.17, there were 627 people (23.4%) with hypertension at the time of screening, 245 of which (39.1%) had never been diagnosed with hypertension before screening at the time. 724 people were on treatment with 1 or more types of drug, however, there were 337 people (46.5%) having their blood pressure not controlled. The statistics showed that 84.9% of volunteers were using at least 1 drug to treat hypertension. Related factors of hypertension are age, sex, overweight/obesity status, smoking, medical history of diabetes and medical history of COVID-19. The rate of subjects who had history of COVID-19 was 36.4%, including 31.6% of hypertension patients. Conclusion: The hypertension percentage of Thua Thien Hue population is still high and the rate of blood pressure control is still limited. There is a relationship between hypertension proportion and history of COVID-19. It is necessary to publish timely intervention measures to reduce the rate of hypertension and its risks to people.
