Background: Drop height has previously been used as an effective programming parameter in plyometric jump training. Less is known about the usage of maximal rebound jump height from a distinct drop height as a parameter for individualized plyometric jump training. Hence, the aim of this study was to contrast the effects of two different drop jump (DJ) training modalities using either the individualized maximal rebound height (MRHT) or a standard (SDHT) drop height on selected measures of physical fitness in young volleyball players.

Electronic address:

RASSF1A is frequently biallelically inactivated in clear cell renal cell carcinoma (ccRCC) due to loss of chromosome 3p and promoter hypermethylation. Here we investigated the cellular and molecular consequences of single and combined deletion of the Rassf1a and Vhl tumor suppressor genes to model the common ccRCC genotype of combined loss of function of RASSF1A and VHL. In mouse embryonic fibroblasts and in primary kidney epithelial cells, double deletion of Rassf1a and Vhl caused chromosomal segregation defects and increased formation of micronuclei, demonstrating that pVHL and RASSF1A function to maintain genomic integrity.

Purpose: Cumulative cisplatin doses of ≥ 200 mg/m improve survival in adults with head-and-neck squamous cell carcinoma (HNSCC) undergoing chemoradiation, but many older adults with HNSCC cannot receive this prognostically relevant dose due to toxicities. This study aims to develop predictive models to assess the likelihood of older adults with HNSCC receiving ≥ 200 mg/m cisplatin during chemoradiation.

Methods: 366 patients from the SENIOR database, an international cohort of adults ≥ 65 years with HNSCC, received definitive chemoradiation with single-agent cisplatin and were analyzed.

Methods for the precise temporal control of cell surface receptor activation are indispensable for the investigation of signaling processes in mammalian cells. Optogenetics enables such precise control, but its application in primary cells is limited by the imperative for genetic manipulation of target cells. We here describe a method that overcomes this obstacle and enables the precise activation of the T cell receptor in nongenetically engineered human T cells by light.

Mycosis fungoides (MF) and Sézary syndrome (SS) are the most common subtypes of the heterogeneous group of cutaneous T-cell lymphomas (CTCL). With the expansion of the biologic treatment landscape, new treatment options have become available in recent years, most notably the C-C chemokine receptor 4 (CCR4)-directed monoclonal antibody mogamulizumab. Based on the phase III pivotal trial, mogamulizumab is recommended by the German S2k guidelines for the second-line treatment of stage IB and above SS and MF, after at least one prior systemic therapy.

Introduction: Cohen syndrome (CS) is an early-onset pediatric neurodevelopmental disorder characterized by postnatal microcephaly and intellectual disability. An accurate diagnosis for individuals with CS is crucial, particularly for their caretakers and future prospects. CS is predominantly caused by rare homozygous or compound heterozygous pathogenic variants in the vacuolar protein sorting-associated 13B () gene, which disrupt protein translation and lead to a loss of function (LoF) of the encoded VPS13B protein.

Previously published recommendations for vegetarian (including vegan) diets for children have highlighted the need for vitamin B12 supplementation. Increased attention to several other key nutrients (including iodine, vitamin D, calcium, and iron) has also been recommended. However, an overview focusing on supplementation guidelines, specifically for vegan infants, has not been published, and a potential requirement for iodine and/or selenium supplementation in (some) vegan infants has not been discussed.

Epidemic infections and spreading antibiotic resistance require diagnostic tests that can be rapidly adopted. To reduce the usually time-consuming adaptation of molecular diagnostic tests to changing targets, we propose the novel approach of a repurposable sensing electrode functionalization with a universal, target-independent oligonucleotide probe. In the liquid phase covering the electrode, the target sequence is amplified by MD LAMP (mediator-displacement loop-mediated isothermal amplification) releasing a generic methylene blue-labeled mediator, which specifically hybridizes to the solid-phase probe.

The use of network meta-analysis (NMA) in sport and exercise medicine (SEM) research continues to rise as it enables the comparison of multiple interventions that may not have been assessed in a single randomised controlled trial. NMA can then inform clinicians on potentially better interventions. Despite the increased use of NMA, we have observed that in the SEM field, a key challenge for author groups can be the assessment and reporting of key assumptions, in particular transitivity and consistency.
