We report the synthesis and extensive characterization of Diazepane and Oxazepane derivatives, followed by their biological evaluation. These compounds were assessed for in vitro and in vivo antimicrobial, anti-inflammatory, and anticancer activities. Among the synthesized molecules, compound 5b demonstrated remarkable antibacterial activity against Staphylococcus aureus and Staphylococcus epidermidis with MIC values of 20 and 40 μg/mL, respectively.

Introduction: Patients with ST-elevation myocardial infarction (STEMI) and late arrival (>12 h) after symptom onset, are at high risk for mortality and heart failure and represent a challenge for management. We aimed to define patient characteristics, management, and outcome of late-arrival STEMI in Israel over the last 20 years.

Methods: We analyzed data of late-arrival STEMI (12-48 h and > 48 h) from the biennial acute coronary syndrome Israeli Surveys (ACSIS), as well as time-dependent changes [early (2000-2010) Vs.

This study examines the microstructural characteristics and corrosion resistance of super duplex stainless steel (SDSS) produced through laser powder bed fusion (LPBF). The analysis shows that the as-printed samples mainly exhibit a ferritic microstructure, which is due to the fast-cooling rates of the LPBF technique. X-ray and microstructure analyses reveal the presence of minor austenite phases in the ferritic matrix.

Humanised xenograft models and cancer cell lines are widely used for preclinical drug evaluation, biological studies, and targeted therapy strategies in cancer research. A humanised mouse model is a laboratory mouse that has been genetically modified to contain specific human genes, cells, or tissues. By introducing human-specific elements into rodents, researchers can create a more accurate representation of human physiological and pathological processes.

The Coronavirus Disease 2019 (COVID-19) pandemic has induced a critical supply of personal protective equipment (PPE) especially N95 respirators. Utilizing respirator decontamination procedures to reduce the pathogen load of a contaminated N95 respirator can be a viable solution for reuse purposes. In this study, the efficiency of a novel hybrid respirator decontamination method of ultraviolet germicidal irradiation (UVGI) which utilizes ultraviolet-C (UV-C) rays coupled with microwave-generated steam (MGS) against feline coronavirus (FCoV) was evaluated.

Background The Corona Virus Disease 2019 (COVID-19) pandemic brought about an unprecedented disruption to global business activities. Physical face-to-face activities must be restricted due to movement control order (MCO). The clients are required to sign the documents physically in the presence of the solicitor who must subsequently attest to the signature of the clients.

We discovered that CO electroreduction strongly favors the conversion of the dominant isotope of carbon (C) and discriminates against the less abundant, stable carbon C isotope. Both absorption of CO in the alkaline electrolyte and CO electrochemical reduction favor the lighter isotopologue. As a result, the stream of unreacted CO leaving the electrolyzer has an increased C content, and the depletion of C in the product is several times greater than that of photosynthesis.

Most acute gastroenteritis (AGE) outbreaks and sporadic cases in developing countries are attributable to infection by human norovirus (HuNoV), the enteric virus mainly transmitted via fecal-contaminated water. However, it has been challenging to study HuNoV due to the lack of suitable systems to cultivate and replicate the virus, hindering the development of treatments and vaccines. Researchers have been using virus-like particles (VLPs) and infectious viral clones to overcome this challenge as alternatives to fresh virus isolates in various in vitro and ex vivo models.

Urethral polyps are one of the rare deformities of the urethra. In most cases, the urethral polyps would not be considered in the differential diagnosis process by a huge number of physicians, mainly owing to the rarity of documented cases in the medical literature and because of the wide variety of unspecified symptoms the urethral polyp might demonstrate. Urethral polyps are more common in males than in females, and they are usually diagnosed at an early age.

The data was collected using a mixed method study of convergent parallel design, conducted using classroom observations, interviews and questionnaires to triangulate the data obtained from the three Premier Polytechnics in Malaysia, which involved nine lecturers and 183 students. The data is useful in focussing on the structure that normally occurs whenever code-switching happens and to test on how effective it is in the learning of English. Further research could also be based on these data as to identify the potential functions of code-switching and its contribution towards the language policy in Malaysia as reference to other countries too.

The Heck cross-coupling reaction is a well-established chemical tool for the synthesis of unsaturated compounds by formation of a new C-C bond. In this study, 1,3-diarylpropene derivatives, designed as structural analogues of stilbenoids and dihydrostilbenoids, were synthesised by the palladium-catalysed reactions of 2-amidoiodobenzene derivatives with either estragole or eugenol. The products were obtained with high (E) stereoselectivity but as two regioisomers.

Propolis is known to exhibit various phytochemical compounds that aid in several biological activities. The current study investigates the phytochemical compounds of ethanolic extract of propolis of (EEP) using Q-TOF LC-MS, its antioxidant properties using DPPH and ABTS radical scavenging assays, total phenolic (TPC) and flavonoid content (TFC), using Folin-Ciocalteu and Aluminium Chloride method, respectively, as well as proapoptotic effects, based on the selected IC of the cytotoxic study conducted for EEP using annexin V-FITC assay. Terpene and polyphenol were among of 17 identified compounds.

Lapatinib, an orally administered small-molecule tyrosine kinase inhibitor (SM-TKI), is an effective treatment for ErbB2-positive breast cancer. However, its efficacy as one of the targeted cancer therapies has been hampered by several adverse effects, especially gastrointestinal toxicity, commonly manifested as diarrhoea. Although it can be generally tolerated, diarrhoea is reported as the most common and most impactful on a patient's quality of life and associated with treatment interruption.

Nanoencapsulation has appeared as an alternative approach to protect the bioactive constituents of essential oils (EOs) and to improve their properties. In this study, Cynometra cauliflora essential oils (CCEOs) were nanoencapsulated in chitosan nanoparticles (CSNPs) using an emulsion-ionic gelation technique. Transmission electron microscopy (TEM) images illustrated a well dispersion and spherical shape of C.

Giant hydronephrosis is an ultimate rare urologic entity; even rarer when it is secondary to a duplex collecting system. Duplex collecting system is a common urologic anomaly with a wide range of clinical symptoms and a variety of associated urologic abnormalities such as an ectopic ureter, ureterocele, vesicoureteral reflux and ureteropelvic junction obstruction. This report presents a case of an 8-year-old boy who had a bilateral duplex collecting system that was revealed accidentally by a bilateral severe hydronephrosis.

Integrating Multibeam Echosounder (MBES) data (bathymetry and backscatter) and underwater video technology allows scientists to study marine habitats. However, use of such data in modeling suitable seagrass habitats in Malaysian coastal waters is still limited. This study tested multiple spatial resolutions (1 and 50 m) and analysis window sizes (3 × 3, 9 × 9, and 21 × 21 cells) probably suitable for seagrass-habitat relationships in Redang Marine Park, Terengganu, Malaysia.

Observational pain scales can help to identify pain in persons with dementia who may have difficulty expressing pain verbally. The Pain Assessment in Impaired Cognition-15 (PAIC15) covers 15 items that indicate pain, but it is unclear how probable pain is, for each summed score (range 0-45). We aimed to determine sensitivity and specificity of cut-offs for probable pain on the PAIC15 against three standards: (1) self-report when able, (2) the established Pain Assessment in Advanced Dementia (PAINAD) cut-off of 2, and (3) observer's overall estimate based on a series of systematic observations.
