The phase I RELEASE clinical trial to evaluate the safety of NK cells in COVID-19.

The severity of COVID 19 symptoms has a direct correlation with lymphopenia, affecting natural killer (NK) cells. SARS-CoV-2 specific "memory" NK cells obtained from convalescent donors can be used as cell immunotherapy. In 2022 a phase I, dose-escalation, single center clinical trial was conducted to evaluate the safety and feasibility of the infusion of CD3/CD56 NK cells against moderate/severe cases of COVID-19 (NCT04578210).

Generation, establishment and characterization of three pluripotent stem cell lines (CVTTHi002-A, CVTTHi003-A and CVTTHi004-A) from primary testicular somatic cells isolated from two prepuberal and one peripuberal Klinefelter Syndrome (47 XXY) patients.

Klinefelter Syndrome (KS) is an aneuploid genetic condition in males characterized by at least one additional copy of the X chromosome. Due to fibrotic degeneration of the testis, these patients suffer infertility in the future. The pathogenic mechanism by which this occurs is still not well known.

Improving Motor Competence of Children: The "Super Quinas" Intervention Program in Portuguese Primary Schools.

Objectives: The objective of this study was to describe the effects of an extra hour of a structured motor program on the motor competence (MC) of children 6-10 years old..

Design: The need for movement interventions to enhance MC among school-aged children has gained vital importance in the last years, given the negative secular trends reported.

Effect of zinc level and the thermal environment on the zootechnical performance and tibia-breaking strength of Japanese quails.

Japanese quails () are sensitive to zinc (Zn) deficiency, a mineral essential for growth, development, and bone health. This study evaluated the effects of different levels of Zn in the diet on zootechnical performance, organ and carcass weight, and tibial breakage resistance in quails from 1 to 42 days of age. A 5 × 2 factorial design was used, consisting of five Zn levels (30, 60, 90, 120, and 150 mg/kg) and two thermal environments (thermal comfort and heat stress), with five replicates of 10 birds per treatment.

Corrigendum: Oligodendrocyte precursor cell-derived exosomes combined with cell therapy promote clinical recovery by immunomodulation and gliosis attenuation.
