Mass of Cepheid V350 Sgr Incorporating Interferometry and the Companion Mass

open access: yesThe Astrophysical Journal
The system V350 Sgr has a classical Cepheid for the primary. Interferometry is presented for the system, and the full orbit is determined. The mass of the companion has been determined from an International Ultraviolet Explorer spectrum and comparison ...

All‐Oral Shorter Treatment Regimens for Multidrug‐ and Rifampicin‐Resistant Tuberculosis: Evaluating Their Effectiveness, Safety, and Impact on the Quality of Life of Patients in Lao PDR

open access: yesTropical Medicine &International Health, Volume 30, Issue 12, Page 1340-1353, December 2025.
ABSTRACT Background Drug‐resistant tuberculosis remains a major public health challenge in Lao PDR, with low second‐line treatment uptake and suboptimal outcomes. To improve effectiveness, safety, and tolerability, a shorter all‐oral regimen for multidrug‐ and rifampicin‐resistant tuberculosis (MDR/RR‐TB) was introduced under the TDR Short, all‐Oral ...

V659 Cen: System Members Updated

open access: yesThe Astronomical Journal
V659 Cen is a classical Cepheid which is part of a multiple system. Previous observations have shown that a hot companion dominates an ultraviolet spectrum and a cooler main-sequence star dominates an XMM-Newton spectrum. The Hubble Space Telescope Space

Rebound of Respiratory Virus Activity and Seasonality to Pre‐Pandemic Patterns

open access: yesJournal of Medical Virology, Volume 97, Issue 11, November 2025.
ABSTRACT The emergence of SARS‐CoV‐2 and the implementation of non‐pharmaceutical interventions (NPIs) profoundly disrupted the transmission dynamics of respiratory viruses, altering their epidemiology and seasonality. However, comprehensive long‐term data on these shifts and their post‐pandemic implications remain limited.

Variable Stars and Stellar Populations in Andromeda XXVII. IV. An Off-centered, Disrupted Galaxy [PDF]

open access: yes, 2017
We present B and V time-series photometry of the M31 satellite galaxy Andromeda XXVII (And XXVII) that we observed with the Large Binocular Cameras of the Large Binocular Telescope. In the field of And XXVII we have discovered a total of 90 variables: 89

Saliva and Anterior Nasal Samples for Detecting Respiratory Viruses in Children

open access: yesAPMIS, Volume 133, Issue 11, November 2025.
ABSTRACT For detecting respiratory viruses, a nasopharyngeal swab sample for polymerase chain reaction (PCR) assays has been the benchmark. Less discomfort related to sampling is requested especially for children, and thus other sample types have been suggested.

Chicago–Carnegie Hubble Program: A Multiwavelength Search for the Effects of Metallicity on the Cepheid Distance Scale. II. Theoretical Models and Synthetic Spectra

open access: yesThe Astrophysical Journal
This is the second of two papers exploring the effects of metallicity on the multiwavelength properties of Cepheids in terms of their multiwavelength period–luminosity (PL) relations, impacting their use as extragalactic distance indicators and ...

Ureteroenteric strictures following retrosigmoid vs. conventional ileal conduit – The MOSAIC study (The DaBlaCa‐16 study)

open access: yesBJU International, Volume 136, Issue 5, Page 858-865, November 2025.
Objectives To evaluate the rate of left‐sided ureteroenteric strictures (UES) following robot‐assisted radical cystectomy (RARC) with a retrosigmoid ileal conduit compared to a conventional ileal conduit in a randomised controlled trial (RCT). Patients and Methods This multicentre, RCT included 303 patients undergoing RARC between May 2020 and August ...
