Eight yeast strains were isolated from jujube fruit surfaces collected in Shanxi and Shandong Provinces, China. All eight strains produced needle-shaped ascospores under suitable conditions. Three separate groups, representing three novel species in the genus Metschnikowia, were recognized by sequence comparisons of the 26S rDNA D1/D2 domain and internal transcribed spacer (ITS) region. The names Metschnikowia sinensis sp. nov. (type strain XY103(T)=AS 2.3110(T)=CBS 10357(T)), Metschnikowia zizyphicola sp. nov. (type strain XY201(T)=AS 2.3111(T)=CBS 10358(T)) and Metschnikowia shanxiensis sp. nov. (type strain XY801(T)=AS 2.3112(T)=CBS 10359(T)) are proposed for the three novel species. Phylogenetic analysis of the 26S rDNA D1/D2 domain sequence showed that these three novel species are clustered in a clade together with the previously described species Metschnikowia fructicola, Metschnikowia andauensis, Metschnikowia pulcherrima and Metschnikowia chrysoperlae.

Challenges in estimating the counterfactual placebo HIV incidence rate from a registration cohort: The PrEPVacc trial.
Clin Trials
December 2024
Medical Research Council Clinical Trials Unit, University College London, London, UK.
Background: There is increasing recognition that the interpretation of active-controlled HIV prevention trials should consider the counterfactual placebo HIV incidence rate, that is, the rate that would have been observed if the trial had included a placebo control arm. The PrEPVacc HIV vaccine and pre-exposure prophylaxis trial (NCT04066881) incorporated a pre-trial registration cohort partly for this purpose. In this article, we describe our attempts to model the counterfactual placebo HIV incidence rate from the registration cohort.

Department of Neurosurgery, The Affiliated Hospital of Guizhou Medical University, Guiyang, Guizhou, PR China.
Objective: This study aims to explore the role of exosome-related genes in breast cancer (BRCA) metastasis by integrating RNA-seq and single-cell RNA-seq (scRNA-seq) data from BRCA samples and to develop a reliable prognostic model.
Methods: Initially, a comprehensive analysis was conducted on exosome-related genes from the BRCA cohort in The Cancer Genome Atlas (TCGA) database. Three prognostic genes (JUP, CAPZA1 and ARVCF) were identified through univariate Cox regression and Lasso-Cox regression analyses, and a metastasis-related risk score model was established based on these genes.
High-Throughput Chemotherapeutic Drug Screening System for Gastric Cancer (Cure-GA).

Department of Surgery, Seoul National University Bundang Hospital, Seongnam, Republic of Korea.
Background: Three dimensional (3D) cell cultures can be effectively used for drug discovery and development but there are still challenges in their general application to high-throughput screening. In this study, we developed a novel high-throughput chemotherapeutic 3D drug screening system for gastric cancer, named 'Cure-GA', to discover clinically applicable anticancer drugs and predict therapeutic responses.
Methods: Primary cancer cells were isolated from 143 fresh surgical specimens by enzymatic treatment.

Perrault syndrome (PS) is an extremely rare autosomal recessive condition characterized primarily by bilateral sensorineural hearing loss in both genders and primary or secondary ovarian failure in females. Neurological features such as cerebral ataxia, peripheral neuropathy, epilepsy, and intellectual disability are frequent manifestations of PS. To date, six genes have been reported to cause PS, and nearly 100 families have been identified worldwide with this syndrome.

This study synthesizes a novel three-dimensional (3D) porous coordination polymer (CP), {[Co(L)₀.₅(H₂O)]·NMP·H₂O} (1), via a solvothermal method in a mixed solvent of water and NMP (1-methyl-2-pyrrolidinone), reacting Co(II) ions with H₄L (1,4-bis(5,6-carboxybenzimidazolylmethyl)benzene). The CP exhibits unique fluorescence properties, emitting at 420 nm under UV light excitation at 350 nm, and serves as a carrier for Mesalazine (MSZ) in therapeutic applications.
