Intercultural competence (IC) is believed to enhance new graduates' entrepreneurial capabilities and employability in this 21st century. This quantitative study investigates learners' perceived levels of IC, regarding its four components: knowledge, attitudes, skills, and awareness [1,2]. An online survey comprising 40 items adapted from Baroudi's questionnaire [3] based on Byram's conceptual framework of IC [1,2] was administered to learners at a recently established state university in the Mekong Delta of Vietnam.

Novel ciprofloxacin composite imprinted materials are synthesized by using co-precipitation polymerization of dual functional monomers (methacrylic acid and 2-vinylpyridine) and polystyrene--divinylbenzene. The intermolecular interactions between monomers and template are evaluated by molecular modeling analysis. The physicochemical properties of the obtained polymers are characterized using FT-IR, TGA, and SEM.

The rapid worldwide spread of SARS-CoV-2 has accelerated research and development for controlling the COVID-19 pandemic. A multi-coronavirus protein microarray was created containing full-length proteins, overlapping protein fragments of various lengths, and peptide libraries from SARS-CoV-2 and four other human coronaviruses. Sera from confirmed COVID-19 patients as well as unexposed individuals were applied to multicoronavirus arrays to identify specific antibody reactivity.

, or Vietnamese ginseng (VG), an endemic species in Vietnam, possesses a unique saponin profile and interesting biological activities. This plant is presently in danger of extinction due to over-exploitation, resulting in many preservation efforts towards the geographical acclimatization of VG. Yet, no information on the saponin content of the acclimatized VG, an important quality indicator, is available.

Background: During the COVID-19 pandemic, decreased volumes of stroke admissions and mechanical thrombectomy were reported. The study's objective was to examine whether subarachnoid haemorrhage (SAH) hospitalisations and ruptured aneurysm coiling interventions demonstrated similar declines.

Methods: We conducted a cross-sectional, retrospective, observational study across 6 continents, 37 countries and 140 comprehensive stroke centres.

Article Synopsis
  • PV is a wild species from Vietnam, discovered in 1973, that has become overexploited due to its economic and therapeutic uses, leading to the need for cultivation.
  • A study developed an HPLC-UV/ELSD method to analyze the saponin content in PV over a 2 to 7-year period, finding a significant increase in saponin levels up to 5 years, with no major changes after that.
  • The research suggests that harvesting PV after 5 years is optimal, identifying key saponins like G-Rg1, G-Rb1, G-Rd, and M-R2 as significant contributors to saponin content, and confirmed the efficacy of the HPLC method

Mastectomy breast reconstruction with autologous tissue is challenging. Oncologic and aesthetic goals face previous surgical scars, radiation, chemotherapy, or other comorbidities. We describe a simple approach for autologous mastectomy reconstruction so that breast and plastic and reconstructive surgeons can maximize aesthetic outcomes and minimize wound complications.

Magic-angle-spinning (MAS) enhances sensitivity and resolution in solid-state nuclear magnetic resonance (NMR) measurements. MAS is obtained by aerodynamic levitation and drive of a rotor, which results in large centrifugal forces that may affect the physical state of soft materials, such as polymers, and subsequent solid-state NMR measurements. Here, we investigate the effects of MAS on the solid-state NMR measurements of a polymer electrolyte for lithium-ion battery applications, poly(ethylene oxide) (PEO) doped with the lithium salt LiTFSI.

The ErbB3-binding protein 1 (Ebp1) has been reported as either an oncogenic regulator or a tumor suppressor in a variety of cancers. Here, we show that Ebp1 p48, a predominant expression isoform, is highly expressed in the majority of human colon tumor cells compared with normal adjacent tissues and its expression is required for the oncogenic activities of these cells. Depletion of Ebp1 expression in primary colon cancer cells inhibits cell proliferation, colony forming, and invasion in vitro as well as tumor formation in vivo and enhances cell sensitivity to irradiation.

ErbB3, a member of the epidermal growth factor receptor family, reportedly plays an essential role in the regulation of cancer progression and therapeutic resistance. Numerous studies have indicated that ErbB3 binding protein 1 (Ebp1), a binding partner for ErbB3, plays an important regulatory role in the expression and function of ErbB3, but there is no agreement as to whether Ebp1 also has an ErbB3-independent function in cancer and how it might contribute to tumorigenesis. In this review, we will discuss the different functions of the two Ebp1 isoforms, p48 and p42, that may be responsible for the potentially dual role of Ebp1 in cancer growth.

  • Babesia microti is a tiny parasite that causes a disease called babesiosis, which can be passed on through blood transfusions, and there isn't a proper test for it yet.
  • Researchers are using new techniques to find specific proteins from the parasite that can help in creating a test to identify past or current infections.
  • They found that one protein, called BmGPI12, is really good at showing if someone is infected and could be used in blood tests to keep people safe from getting the disease through blood donations.
