Novel 4-piperidone derivatives 2a-f are disclosed as potent cytotoxins. Many of these compounds are more potent than the reference drug melphalan. The compounds in series 2, 4-7 display selective toxicities toward various neoplasms compared to some normal cells. 2a is one of the promising lead molecules that display >11-fold higher growth inhibiting potency than 5-fluorouracil against human colon cancer cells. 2a induces apoptosis, DNA fragmentation, and cleavage of poly ADP-ribose polymerase.

Inferior sectoral chorioretinopathy in two patients with novel heterozygous mutations.
Ophthalmic Genet
January 2025
Departments of Medical Genetics and Ophthalmology & Visual Sciences, University of Alberta, Edmonton, Alberta, Canada.
Background: Pathogenic variants in , a kinesin family gene, cause MCLMR and FEVR. In MCLMR, chorioretinal atrophy is present in the majority of cases and can be a helpful diagnostic sign.
Cases: We present the cases of two patients with chorioretinal atrophy and microcephaly who carry novel mutations.
Identification and characterization of a novel QTL for barley yellow mosaic disease resistance from bulbous barley.
Plant Genome
March 2025
Key Laboratory of Plant Functional Genomics of the Ministry of Education/Jiangsu Key Laboratory of Crop Genomics and Molecular Breeding/Jiangsu Co-Innovation Center for Modern Production Technology of Grain Crops/Joint International Research Laboratory of Agriculture and Agri-Product Safety of Ministry of Education of China, Yangzhou University, Yangzhou, China.
Winter barley (Hordeum vulgare) production areas in the middle and lower reaches of the Yangtze River are severely threatened by barley yellow mosaic disease, which is caused by Barley yellow mosaic virus and Barley mild mosaic virus. Improving barley disease resistance in breeding programs requires knowledge of genetic loci in germplasm resources. In this study, bulked segregant analysis (BSA) identified a novel major quantitative trait loci (QTL) QRym.

Background And Aims: Many vaping products feature bright colors and novel brand names and flavor descriptors, which may appeal to youth. We measured the strength of the associations between e-liquid packaging design (branded, white standardized or white standardized limiting brand and flavor descriptors) and perceived peer interest in trying the e-liquids among youth.
Design: A between-subjects online experiment.
Novel combination therapy targeting oncogenic signaling kinase P21 activated Kinase-1 and chemotherapeutic drugs against triple negative breast cancer.
Mol Cancer Ther

Most of the triple negative phenotype or basal-like molecular subtypes of breast cancers are associated with aggressive clinical behaviour and show poor disease prognosis. Current treatment options are constrained, emphasizing the need for novel combinatorial therapies for this particular tumor subtype. Our group has demonstrated that functionally active p21 activated kinase 1 (PAK1) exhibits significantly higher expression levels in clinical triple negative breast cancer (TNBC) samples compared to other subtypes, as well as adjacent normal tissues.

CNS Neurosci Ther
January 2025
Department of Neurology, The Affiliated Brain Hospital of Nanjing Medical University, Nanjing, China.
Objectives: Parkinson's disease (PD) is characterized by olfactory dysfunction (OD) and cognitive deficits at its early stages, yet the link between OD and cognitive deficits is also not well-understood. This study aims to examine the changes in the olfactory network associated with OD and their relationship with cognitive function in de novo PD patients.
Methods: A total of 116 drug-naïve PD patients and 51 healthy controls (HCs) were recruited for this study.
