Molecular structure and charge density analysis of p-methoxybenzoic acid (anisic acid) [PDF]

, 1997
A concerted X-ray and ab initio SCF-MO study of the structure and charge density of p-methoxybenzoic acid (anisic acid) is reported. An extensive X-ray data set (7401 reflections) was measured on a single crystal using Mo Kα radiation and the structure ...

Higher Genetic Diversity Across Several Small Patches Compared to a Single Large Patch: A Within‐Species Test of SLOSS

Evolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT The SLOSS (Single Large or Several Small) debate is crucial in reserve design, focusing on evaluating the conservation efficacy of a single large reserve versus multiple small reserves for species preservation. While accumulating evidence suggests that multiple small reserves may conserve greater species diversity, the question of how to ...

A Digital Low Dispersion Spectral Library Covering the 3500-7500AA Region Using the SAAO Radcliffe 1.9m Telescope's Cassegrain Spectrograph

, 2013
We have created a digital spectral library, using low resolution optical spectra, of photometric and spectral standard stars. The data were acquired using the Cassegrain Spectrograph installed on the 1.9m Radcliffe telescope at the South African ...

Combining ability and heterosis in partial resistance to gray leaf spot in elite maize (Zea mays L.) genotypes

Crop Science, Volume 66, Issue 1, January/February 2026.
Abstract Six sets of 48 maize (Zea mays L.) inbred lines, and their 96 single crosses generated using the North Carolina Mating Design II system, were evaluated for resistance to gray leaf spot (GLS). The aim of the study was to assess the implications of combining ability, heterotic effects, and potence ratio in breeding for GLS resistance in maize ...

HD 11397 and HD 14282 - Two new barium stars?

, 2008
We have performed a detailed abundance analysis of the content of s-process elements of two dwarf stars with suspected overabundace of those elements. Such stars belong to a special kinematic sample of the solar neighborhood, with peculiar kinematics and

Endogenous Processes Underlying Clock‐Like Mutational Signatures

Genes, Chromosomes and Cancer, Volume 65, Issue 1, January 2026.
ABSTRACT Wellcome Trust scientists have shown that “mutational signatures” in specific nucleotide contexts accumulate in genomes of mammalian tissues, providing clues to underlying causes of specific signatures. Analysis of cancer genomes has identified more than 50 single‐base substitution (SBS) signatures, with SBS1, SBS5, and SBS40 linked to aging ...

TDP1/TOP1 ratio as a promising indicator for the response of small cell lung cancer to topotecan [PDF]

, 2014
BACKGROUND AND OBJECTIVE Small cell lung cancer (SCLC) is one of the most challenging tumors to treat due to high proliferation rate, early metastatic dissemination and rapid development of chemotherapy resistance.

Phenothiazine Derivatives and Their Impact on the Apoptosis Processes: A Review

Journal of Applied Toxicology, Volume 46, Issue 1, Page 42-60, January 2026.
ABSTRACT Phenothiazine derivatives have been used for decades as antipsychotic drugs in multiple mental health and physical conditions treatment (schizophrenia, mania in bipolar disorder, and psychosis). Epidemiological studies have shown that people with schizophrenia are less likely to suffer from cancer, which indicates the ability of antipsychotics

Deep Learning for Hyperpolarized NMR of Intrinsically Disordered Proteins without Resolution Loss: Access to Short‐Lived Intermediates

Chemistry – A European Journal, Volume 31, Issue 59, October 22, 2025.
Abstract The inherently low sensitivity of solution‐state Nuclear Magnetic Resonance (NMR) has long limited its ability to characterize transient biomolecular states at atomic resolution. While dissolution dynamic nuclear polarization (dDNP) offers a compensating signal enhancement, its broader use has been hindered by rapid polarization decay, causing
