Defining MRI-based follow-up protocol for primary central nervous system lymphoma.

Background: The optimal follow-up protocol for primary central nervous system lymphoma (PCNSL) is unclear. This is the first study to evaluate the benefit of structured follow-up imaging of PCNSL with respect to the timing of relapse.

Methods: A total of 198 PCNSL patients (57.

Patient's HLA Genotype Is Associated With the Risk of Central Nervous System Dissemination and Clinical Disease Presentation in Diffuse Large B-cell Lymphoma.

Background/aim: Central nervous system (CNS) involvement in aggressive B-cell lymphoma, either as a primary or secondary event to systemic disease, portends a poor prognosis. This study sought to identify patients at high risk for CNS relapse by analyzing their human leukocyte antigen (HLA) genotypes.

Patients And Methods: We retrospectively examined the HLA genotypes of 164 patients with systemic lymphoma, primary CNS lymphoma, and CNS relapse of systemic lymphoma.

Spiritual well-being correlates with quality of life of both cancer and non-cancer patients in palliative care - further validation of EORTC QLQ-SWB32 in Finnish.

Background: The European Organisation for Research and Treatment of Cancer (EORTC) has developed the Spiritual Well-being Questionnaire (EORTC QLQ-SWB32), a measure of spiritual well-being validated with people receiving palliative care for cancer, although its usefulness is not restricted to that population. We aimed to translate and validate this tool in Finnish and to study the relationship between spiritual well-being (SWB) and quality of life (QOL).

Methods: A Finnish translation was produced according to the guidelines of EORTC and included forward- and back-translations.

Survival of patients with mantle cell lymphoma in the rituximab era: Retrospective binational analysis between 2000 and 2020.

Mantle cell lymphoma (MCL) is a rare peripheral B-cell lymphoma characterised by eventual relapse and progression towards a more aggressive disease biology. With the introduction of rituximab- and cytarabine-based immunochemotherapy regimens, the prognosis of the disease has changed dramatically over the last two decades. To assess the real-world survival of patients with MCL, we used a population-based cohort of 564 patients with MCL who were diagnosed and treated between 2000 and 2020.

Integrin alpha 10, CD44, PTEN, cadherin-11 and lactoferrin expressions are potential biomarkers for selecting patients in need of central nervous system prophylaxis in diffuse large B-cell lymphoma.

Central nervous system (CNS) relapse is a devastating complication that occurs in about 5% of diffuse large B-cell lymphoma (DLBCL) patients. Currently, there are no predictive biological markers. We wanted to study potential biomarkers of CNS tropism that play a role in adhesion, migration and/or in the regulation of inflammatory responses.

Distinct roles of four gelsolin-like domains of Caenorhabditis elegans gelsolin-like protein-1 in actin filament severing, barbed end capping, and phosphoinositide binding.

Caenorhabditis elegans gelsolin-like protein-1 (GSNL-1) is a new member of the gelsolin family of actin regulatory proteins [Klaavuniemi, T., Yamashiro, S., and Ono, S.

Characterization of the interaction between Actinin-Associated LIM Protein (ALP) and the rod domain of alpha-actinin.

Background: The PDZ-LIM proteins are a family of signalling adaptors that interact with the actin cross-linking protein, alpha-actinin, via their PDZ domains or via internal regions between the PDZ and LIM domains. Three of the PDZ-LIM proteins have a conserved 26-residue ZM motif in the internal region, but the structure of the internal region is unknown.

Results: In this study, using circular dichroism and nuclear magnetic resonance (NMR), we showed that the ALP internal region (residues 107-273) was largely unfolded in solution, but was able to interact with the alpha-actinin rod domain in vitro, and to co-localize with alpha-actinin on stress fibres in vivo.

Caenorhabditis elegans gelsolin-like protein 1 is a novel actin filament-severing protein with four gelsolin-like repeats.

The gelsolin family of proteins is a major class of actin regulatory proteins that sever, cap, and nucleate actin filaments in a calcium-dependent manner and are involved in various cellular processes. Typically, gelsolin-related proteins have three or six repeats of gelsolin-like (G) domain, and each domain plays a distinct role in severing, capping, and nucleation. The Caenorhabditis elegans gelsolin-like protein-1 (gsnl-1) gene encodes an unconventional gelsolin-related protein with four G domains.

Backbone NMR assignment of the internal interaction site of ALP.

Earlier reports have shown that ALP has an internal interaction site. We were able to stabilize the structure of this unfolded part to a great extent by aspartic acid, which allowed the backbone assignment. No secondary structure of the polypeptide was observed.

Zasp/Cypher internal ZM-motif containing fragments are sufficient to co-localize with alpha-actinin--analysis of patient mutations.

Z-band alternatively spliced PDZ-containing protein (ZASP/Cypher) has an important role in maintaining Z-disc stability in striated and cardiac muscle. ZASP/Cypher interacts through its PDZ domain with the major Z-disc actin cross-linker, alpha-actinin. ZASP/Cypher also has a conserved sequence called the ZM-motif, and it is found in two alternatively spliced exons 4 and 6.

The ZASP-like motif in actinin-associated LIM protein is required for interaction with the alpha-actinin rod and for targeting to the muscle Z-line.

The Z-line is a specialized structure connecting adjacent sarcomeres in muscle cells. alpha-Actinin cross-links actin filaments in the Z-line. Several PDZ-LIM domain proteins localize to the Z-line and interact with alpha-actinin.

Surfactant protein D gene polymorphism associated with severe respiratory syncytial virus infection.

Respiratory syncytial virus (RSV) is the major respiratory tract pathogen in infancy. Host-related differences in susceptibility to severe RSV infection suggest that genetic factors may play a role. In this study, a candidate-gene approach was used to study whether the surfactant protein D (SP-D) gene polymorphism associates with severe RSV infection.
