Introduction: A series of benzylidene derivatives of fenobam and its thio analogues (1-22) have been evaluated for their cytotoxicity against breast cancer (MCF-7, MDA-MB-231), ovarian cancer (A2780, SKOV-3) and cervical cancer (HELA) cell lines.

Method: These compounds (1-22) exhibited 72-83% inhibition of Erk activity against the ovarian cancer cell line (A2780). Compounds 3 and 20 showed the highest DNA damage effect in Comet Assay against the A2780 cancer cell line as compared to the other tested analogues (4, 8, 11, 12, and 13) by using % Tail DNA and OTM.

Article Synopsis
  • The study investigates the hepatoprotective (liver-protecting) properties of a popular Ayurvedic herb by analyzing its phytochemicals using targeted metabolomics.
  • Different fractions of the herb's hydro-alcoholic extract were tested for antioxidant and protective effects on liver cells (HepG2), with the n-butanol fraction showing the best results.
  • UPLC-QTOF-MS analysis identified 17 secondary metabolites in the active fraction, some of which may inhibit the CYP2E1 enzyme, potentially reducing toxicity from APAP (acetaminophen) in liver cells.

To become registered radiation worker as radiographer, nuclear medicine (NM) technologist, or radiotherapist in Australian health system, a 4-y bachelor's degree, or a 2-y master's degree in medical imaging (MI), NM, or radiation therapy (RT) approved by the Australian Health Practitioner Regulation Agency is required. During their supervised clinical practice period, it is crucial to monitor students' occupational radiation dose as their annual dose limit is 1 mSv y-1 unlike regular occupational dose of 20 mSv y-1. In this study, the distribution and trend of occupational dose among over 300 radiography, NM, and radiotherapy student practitioners per year in an Australian university are analyzed over a period of 10 y (2013-22).

Non-coding RNAs (lncRNAs) play critical roles in various cellular processes, including a novel form of regulated cell death known as disulfidptosis, characterized by accumulating protein disulfide bonds and severe endoplasmic reticulum stress. This review highlights the therapeutic potential of lncRNAs in regulating disulfidptosis for cancer treatment, emphasizing their influence on key pathway components such as GPX4, SLC7A11, and PDIA family members. Recent studies have demonstrated that targeting specific lncRNAs can sensitize cancer cells to disulfidptosis, offering a promising approach to cancer therapy.

Unlabelled: Human Immunodeficiency Virus (HIV) has become an epidemic causing Acquired Immunodeficiency Syndrome (AIDS). Highly active antiretroviral therapy (HAART) consists of Nucleoside Reverse Transcriptase Inhibitors (NRTIS), Nucleotide Reverse Transcriptase Inhibitors (NtRTIS), and Non- Nucleoside Reverse Transcriptase Inhibitors (NNRTIS) with HIV Protease Inhibitors (HIV PIs). However, the emergence of resistant strains of NNRTIS necessitates the search for better HIV-1-RT inhibitors.

The burgeoning field of quantum sensing hinges on the creation and control of quantum bits. To date, the most well-studied quantum sensors are optically active, paramagnetic defects residing in crystalline hosts. We previously developed analogous optically addressable molecules featuring a ground-state spin-triplet centered on a Cr ion with an optical-spin interface.

Nodular calcium poses a great challenge during coronary intervention. The presence of nodular calcium is associated with poor post-procedural outcomes. Without debulking the nodular calcium, it is extremely difficult to pass the coronary hardwires including the balloons and drug-eluting stents across the lesion.

An ensemble of nanosystems can be considered to improve magnetic resonance imaging (MRI) transverse relaxivity. Herein, an interacting superparamagnetic competing structure of an isotropic-anisotropic trimagnetic hybrid nanosystem, γ-FeO@δ-MnO@NiFeO, is considered for MRI relaxivity exploration. The interacting superparamagnetic system reveals fascinating dynamic magnetic behavior, where flower-shaped two-dimensional flakes are decorated over nanoparticles.

Moiré superlattices with a robust twist proximity effect in the low-dimensional regime can facilitate nanoscale thermoelectric devices. In pristine systems, the low efficiency and lack of proficient control of thermoelectric properties impede desirable advancements in the field of energy conversion. In the present study, we demonstrate remarkable macroscopic thermoelectric response as a consequence of microscopic band structure modulation via the twist proximity in an engineered CrI/1T-MoS moiré superlattice.

In the current study, two sets of compounds: (E)-1-(2-(4-substitutedphenyl)-2-oxoethyl)-4-((hydroxyimino)methyl)pyridinium derivatives (3a-3e); and (E)-3-(substitutedbenzoyl)-7-((hydroxyimino)methyl)-2-substitutedindolizine-1-carboxylate derivatives (5a-5j), were synthesized and biologically evaluated against two strains of Mycobacterial tuberculosis (ATCC 25177) and multi-drug resistant (MDR) strains. Further, they were also tested in vitro against the mycobacterial InhA enzyme. The in vitro results showed excellent inhibitory activities against both MTB strains and compounds 5a-5j were found to be more potent, and their MIC values ranged from 5 to 16 μg/mL and 16-64 μg/mL against the M.

We report a rare case of multiple nodular calcium in the left anterior descending coronary artery in an octogenarian presenting with unstable angina. Dilatation with the noncompliant and scoring balloon could not yield the nodular calcium and it was only the cutting balloon that could yield the nodular calcium and successful coronary angioplasty could be accomplished with good angiographic results with distal Thrombolysis in Myocardial Infarction (III) flow. This case demonstrates the unique role of cutting balloons in the angioplasty of coronary lesions with multiple nodular calcium.

Primary pulmonary salivary gland-type carcinomas are rare malignancies arising from minor salivary gland tissue in the lower respiratory tract. Given their rarity, constituting <1% of all primary lung malignancies, their epidemiological features and outcomes remain poorly documented. This study analyzed data from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database to identify primary pulmonary salivary gland carcinomas, including the most prevalent tumor types.

Article Synopsis
  • Large-scale superconducting quantum processors face challenges due to the complex microscopic features in solid-state devices, primarily using aluminium oxide (AlO) tunnel Josephson junctions for nonlinearity in quantum operations.
  • Traditional analyses often rely on an ideal sinusoidal current-phase relation, which only applies in very low-transparency conditions, but new findings reveal this doesn’t accurately represent the energy spectra of transmon artificial atoms.
  • A mesoscopic model shows significant contributions from higher Josephson harmonics, improving predictions of energy spectra and suggesting that engineered harmonics could minimize charge-related errors in transmon qubits, enhancing their performance for quantum technologies.

Single-layer half-metal magnets offer exciting scope in spin electronic quantum applications owing to improved spin transport, reduced interfacial resistance and streamlined device fabrication. Herein, we report the emergence of sign-flipping intrinsic anomalous Hall conductivity (AHC) as a result of changes in Berry curvature under an external electric field and half metallicity in a lateral heterostructure composed of centrosymmetric metallic monolayers 1T-NbSe and 1T-VSe. The metallic monolayers 1T-NbSe and 1T-VSe laterally interfaced along the zigzag orientation break inversion symmetry at the interface and result in distinctive Berry curvature features.
