Establishing a cryopreserved biobank of living tumor tissues for drug sensitivity testing.

The cryopreservation of cancer tissues to generate frozen libraries is a common practice used worldwide for storing patient samples for later applications. However, frozen samples stored by existing methods cannot be used for initiating living cell cultures, such as patient-derived tumor organoids (PDOs), which offer great potential for personalized treatment. To overcome this challenge, we developed a novel procedure for culturing PDOs using frozen live tumor tissues.

Antiretroviral Therapy within Two Years of HIV Acquisition is Associated with Fewer Viral Blips: A Retrospective Analysis of Over 20 Years of Data from the U.S. Military HIV Natural History Study.

Introduction: Viral blips have been associated with larger reservoir size and slower decay. Earlier antiretroviral therapy (ART) initiation may decrease the risk of blips.

Methods: We analyzed participants from the U.

Clinical outcome and peripheral CD4 T profile in impending myasthenic crisis: A prospective cohort study.

Impending Myasthenic Crisis (MC) is defined as a rapid worsening of myasthenia gravis (MG) that can progress to respiratory failure within days to weeks. The clinical data regarding the outcome and peripheral immune profile is limited. This multicenter cohort enrolled 37 patients with impending MC who were given timely rescue therapies from six university hospitals (n = 272).

Alkali-extracted rhamnogalactoarabinan from Chaetomorpha linum: Characterisation and anti-type 2 diabetic effect.

Sulphated galactoarabinans, extracted from members belonging to the Cladophoraceae (Chlorophyceae) family, have been reported to have potential as novel anti-diabetic agents. However, relatively few studies have investigated this research topic. In the present study, a water-soluble polysaccharide designated CBS2 was obtained from Chaetomorpha linum using dilute alkaline solution, preparative anion exchange, and size-exclusion chromatography.

[Analysis of clinical value of platelet antibody screening in 95 987 inpatients].

Objective To analyze the distribution of platelet antibodies in hospitalized patients and explore the clinical significance of platelet antibody detection. Methods A total of 95 987 hospitalized patient cases from a tertiary hospital in Xi'an from April 1, 2021 to December 31, 2023 were collected. Platelet antibodies were detected by solid-phase agglutination method.
