Active and passive organic carbon fluxes during a bloom in the Southern Ocean (South Georgia).

The Controls Over Mesopelagic Interior Carbon Storage (COMICS) cruise DY086 took place aboard the RRS Discovery in the South Atlantic during November and December, 2017. Physical, chemical, biogeochemical and biological data were collected during three visits to ocean observatory station P3, off the coast of South Georgia, during an austral spring bloom. A diverse range of equipment including CTD-rosette, Acoustic Doppler Current Profiler (ADCP), net deployments, marine snow catchers (MSCs), Stand Alone Pump System (SAPS) and PELAGRA Sediment Traps were used to produce a comprehensive, high-quality dataset.

Identification of potential SARS-CoV-2 Nsp1 inhibitors from Piper sarmentosum Roxb. using molecular docking.

Nsp1 in SARS-CoV-2 is a key protein that increases the virus's pathogenicity and virulence by binding to the host ribosome and blocks the 40S ribosomal subunit channel, which effectively impedes the mRNA translation as well as crippling the host immune system. Previous studies revealed that the N-terminal in Nsp1 is part and parcel of Nsp1 efficiency, and mutations in its core residues have weakened the protein's. This knowledge persuades us to carry out the in silico screening on plant compounds of Piper sarmentosum Roxb.

Association Between Vascular Endothelial Growth Factor (VEGF) +936C/T Polymorphism (rs3025039) and Preeclampsia Among Myanmar Pregnant Women.

The vascular endothelial growth factor (VEGF) polymorphism is associated with preeclampsia since its abnormal expression plays an important role in vasculogenesis in placenta formation. Thus, this study is aimed at analyzing the association between VEGF +936C/T polymorphism and the risk of preeclampsia. To assess the causal relationship, a hospital-based cross-sectional analytical study was carried out among 204 Myanmar pregnant women during the period of January 2018-September 2020.

Lignans and coumarins from the stem bark of (Wall. ex G. Don) Benth. ex Hook. f.).

In the first phytochemical investigation of specialized metabolites from the stem bark of , which is used in different traditional medicines, including those of Myanmar and China, five lignans (-) and three coumarins (-) were isolated by semipreparative HPLC separations and identified mainly by 1D and 2D NMR spectral analysis. The radical scavenging activity of isolated compounds was tested using the DPPH method. Noteworthy, most lignans exhibited antiradical effects comparable to vitamin C and gallic acid.

Chondrogenesis with Autologous Peripheral Blood Stem Cells for End-Stage Ankle Arthritis: Report of Three Cases.

End-stage ankle arthritis represents an "unmet medical need", awaiting an appropriate time for joint arthroplasty or arthrodesis. We report three cases of end-stage ankle arthritis treated along the principles developed for chondrogenesis of the knee joint with autologous peripheral blood stem cells, resulting in reversal of the ankle arthritis. The improvement in clinical outcome measure scores (Ankle Osteoarthritis Scale total score) with a minimum two-year follow-up were comparable to total ankle replacement (TAR), arthroscopic ankle arthrodesis (AAA) and open ankle arthrodesis (OAA).

Lab-on-Chip for In Situ Analysis of Nutrients in the Deep Sea.

Microfluidic reagent-based nutrient sensors offer a promising technology to address the global undersampling of ocean chemistry but have so far not been shown to operate in the deep sea (>200 m). We report a new family of miniaturized lab-on-chip (LOC) colorimetric analyzers making in situ nitrate and phosphate measurements from the surface ocean to the deep sea (>4800 m). This new technology gives users a new low-cost, high-performance tool for measuring chemistry in hyperbaric environments.

Infectious control measures during the COVID-19 pandemic have led to the propensity toward telemedicine. This study examined the impact of telemedicine during the pandemic on the long-term outcomes of ST-segment elevation myocardial infarction (STEMI) patients. This study included 288 patients admitted 1 year before the pandemic (October 2018-December 2018) and during the pandemic (January 2020-March 2020) eras, and survived their index STEMI admission.

Arthroscopic Subchondral Drilling Followed by Injection of Peripheral Blood Stem Cells and Hyaluronic Acid Showed Improved Outcome Compared to Hyaluronic Acid and Physiotherapy for Massive Knee Chondral Defects: A Randomized Controlled Trial.

Purpose: The purpose of this study was to evaluate the safety and efficacy of intra-articular injections of autologous peripheral blood stem cells (PBSCs) plus hyaluronic acid (HA) after arthroscopic subchondral drilling into massive chondral defects of the knee joint and to determine whether PBSC therapy can improve functional outcome and reduce pain of the knee joint better than HA plus physiotherapy.

Methods: This is a dual-center randomized controlled trial (RCT). Sixty-nine patients aged 18 to 55 years with International Cartilage Repair Society grade 3 and 4 chondral lesions (size ≥3 cm) of the knee joint were randomized equally into (1) a control group receiving intra-articular injections of HA plus physiotherapy and (2) an intervention group receiving arthroscopic subchondral drilling into chondral defects and postoperative intra-articular injections of PBSCs plus HA.

Effectiveness of successful intelligence training program: A meta-analysis.

This study assessed Robert Sternberg's theory of successful intelligence (TSI) training in teaching and learning situations to improve academic achievement, triarchic (analytical, creative, practical) thinking, and socioemotional outcomes. The analyses included all references from several databases (Web of Science, ProQuest, Elsevier, Google Scholar, and bibliographies of related articles) from 1998 to 2019 that implemented the successful intelligence training program in a variety of ways. Possible moderators, selection criteria, subject areas, and grade levels were investigated.

Time-of-flight secondary ion mass spectrometry fragment regularity in gallium-doped zinc oxide thin films.

Time-of-flight secondary ion mass spectrometry fragment analysis remains a challenging task. The fragment appearance regularity (FAR) rule is particularly useful for two-element compounds such as ZnO. Ion fragments appearing in the form of ZnO obey the rule [Formula: see text] in the positive secondary ion spectrum and [Formula: see text] in the negative spectrum where the valence of Zn is + 2 and that of O is - 2.

Variable Anatomy of the Middle Cerebral Artery from Its Origin to the Edge of the Sylvian Fissure: A Direct Fresh Brain Study.

The middle cerebral artery (MCA) is a major artery supplying blood to the brain and a common site of surgically treatable intracranial aneurysms. The MCA has anatomic variations that may have clinical significance. In order to investigate and document the extent of such variations, the MCA in 100 fresh brain hemispheres from 50 deceased patients, obtained from the Police Surgeon Office, Yangon General Hospital, Myanmar, was dissected and examined.

Manometry of the Human Ileum and Ileocaecal Junction in Health, Disease and Surgery: A Systematic Review.

The terminal ileum and ileocaecal junction form a transition zone in a relatively inaccessible portion of the gastrointestinal tract. Little is known about the motility of this region with few detailed studies, indicating the need for a robust synthesis of current knowledge. This review aimed to evaluate the quantitative and qualitative data on the manometry findings of the terminal ileum and ileocaecal junction during the fasting and post-prandial periods in healthy individuals and patients with motility disorders or patients after bowel surgery.

Treatment of gastric adenocarcinoma at a New Zealand centre: meeting the challenges of a low volume country.

Background: Surgical treatment of gastric cancer in New Zealand is challenging because of a low annual incidence of 400 patients and population dispersal over a wide area with little data on regional treatment trends and outcomes. This investigation was undertaken to evaluate the surgical outcomes of gastric cancer patients presenting to a single upper gastrointestinal centre (WDHB, Waitemata District Health Board) and to compare these to national and international standards.

Methods: Data on 135 patients with histologically proven gastric adenocarcinoma presenting between January 2010 and December 2014 were reviewed and compared with nationally available procedural volume data.
