We developed a scoring system to predict 1-year survival after radiosurgery for 1-3 brain metastases. This study aimed validate this system.Seventy-six new patients were included in validation study. Like the original scoring-system, three factors (age, performance status, extra-cranial metastases) used. For each factor, rates % divided by 10, and scoring-points added patient.Patient's scores 11, 13, 14, 16 or 17 points with ranging between 31% 80%. Two groups, 10-14 16-17 formed. In 14-16...
Keteleeria davidiana (C.E.Bertrand) Beissn. is a species of conifer native to southern China, Laos and Vietnam. The has been listed as vulnerable in Essential oil samples have isolated from leaves, twigs wood, their compositions investigated for the first time by combination chromatographic spectroscopic techniques [GC-FID, GC-MS and13C NMR]. composition leaf essential was dominated α-pinene (28.1%), β-pinene (15.8%) (E)-β-caryophyllene (13.8%). Twig contained mainly (37.9%) (24.7%)...
Aim: To evaluate the role of rotating gamma system (RGS) radiosurgery for low-grade brainstem gliomas. Patients and Methods: Thirty-seven patients undergoing RGS at Bach Mai Hospital Hanoi glioma were included in this prospective interventional study. The median dose was 12 Gy (range=8-16 Gy). Endpoints response to given as change size (maximum diameter), survival adverse events. Follow-up performed 36 months. Three dose-groups (<13, 13-14 >14 Gy) compared survival. Results: Mean...
Background: To determine the relationship between Helicobacter pylori ( H. ) infection and precancerous gastric lesions: atrophic gastritis (AG) intestinal metaplasia (IM) dysplasia. Methods: A total of 347 dyspeptic patients, including 141 ‐positive patients 206 ‐negative were studied alongside age‐ sex‐matched controls. The underwent gastroscopy endoscopic biopsy for detection , histological examinations. was detected by a urease test (CLO; Delta West; Bentley, Australia), histology...
Abstract Through a meticulous examination of edicts issued by both imperial courts and Christian missionaries, this article posits that the ‘ritual issue’ – i.e., divergence in ritualistic practices values between Christianity indigenous religions constituted principal obstacle to proliferation Vietnam 17th 19th centuries. Notably, paper identifies substantive transformation perception issue.’ During 18th centuries under Trịnh-Nguyễn lords, issue was predominantly approached through...
Pogostemon auricularius (L.) Hassk. (Lamiaceae) is an erect or procumbent, strongly smelling annual herb, 40-100 cm tall. Stem simple laxly branched, weak, bluntly 4-angular, pubescent with spread hairs. Leaves decussate, elliptical to oval, 4-6 ´ 2-3 cm; base cuneate; apex acute; margin uregularly surate, flowers and fruits throughout the year. This plant distributes in many provinces of Vietnam (Sonla, Laichau, Laocai, Caobang, Hagiang, Langson, Phutho, Thuathien-Hue, Gialai, Kontum,...
Top-of-the-basilar artery occlusion frequently causes infarction of the midbrain, thalamus, and portions temporal occipital lobes as vascular supply these regions comes from posterior communicating cerebral arterial tributaries basilar artery. Clinical signs include an array visual, oculomotor, behavioral abnormalities, usually without prominent motor dysfunction, which makes diagnosis challenging for those inexperienced with sign. We describe a 59-year-old male presenting acute ischemic...
Illigera trifoliata ssp.cucullata (Merr.)Kubitzki (Hernandiaceae) is a liana distributed mainly in the tropical regions of Asia.Nothing known on phytochemicals produced by this species.Oil samples have been isolated from leaves, and stems, analyzed combination chromatographic spectroscopic techniques [GC(FID), GC-MS 13 C NMR].The compositions leaf stem oils were dominated phellandrene (25.8 29.2%), -pinene (26.0 9.5%) -phellandrene (12.8 15.8%), followed limonene (5.5 8.1%) -pinene (7.5...
A rare noriridoid and six known phenolic compounds were isolated from the parasite plant Rhopalocnemis phalloides. Using spectroscopic methods, these identified as 10-acetoxy- cis-2-oxabicyclo[4.3.0]nonan-7-en-3-one (1), p-hydroxybenzoic acid (2), protocatechuic (3), gallic (4), coniferyl aldehyde (5), l- O-trans-cinnamoyl-β-D-glucoside (6), coniferin (7). The compound is first reported family Balanophoraceae. Of compounds, had strongest inhibitory effect on nitric oxide production (IC 50 = 8.24 μM).
