Purpose: Definitive intent radiation therapy (RT) for early-stage mucosa-associated lymphoid tissue (MALT) lymphoma typically includes a dose of 24 to 30 Gy. While modest, these doses may have associated toxicity. For patients with indolent B-cell lymphoma, there is increasing support for the use of ultra-low-dose RT (ULDRT) using 4 Gy in 2 fractions as part of a response-adapted approach, as high rates of complete response have been documented.

Introduction: Epithelial and endothelial cells modulate innate immune responses in the lung, including the arrival of neutrophils (PMN), which are crucial cells for the antibacterial host defense. Cells are exposed to prokaryotic RNA (pRNA) during bacterial infections and different pRNA may promote or attenuate the inflammatory response on different immune cells. Pseudomonas aeruginosa (PAE) can cause severe pneumonia and has several immune-evading mechanisms.

Muscle wasting is a universal hallmark of aging which is displayed by a wide range of organisms, although the causes and mechanisms of this phenomenon are not fully understood. We used Drosophila to characterize the phenomenon of spontaneous muscle fiber degeneration (SMFD) during aging. We found that SMFD occurs across diverse types of somatic muscles, progresses with chronological age, and positively correlates with functional muscle decline.

Wilms tumor has been selected as an index tumor by the WHO Global Initiative for Childhood Cancer with the aim to improve cure rates worldwide. Nevertheless, there is a scarcity of published data on outcomes beyond those of the major cooperative groups. Therefore, we conducted a retrospective analysis including all patients with Wilms tumor treated at our referral center in Uruguay between 1995 and 2020.

Numerous, and often largely overlapping, observational pain assessment tools have been developed specifically to assess pain in older adults with dementia under the assumption that a specialized approach is necessary to evaluate pain in this population. However, this assumption has never been tested empirically. As an empirical test of this implicit assumption, our goal was to compare existing tools for people living with dementia (with respect to psychometric properties), not only against each other, but also against a tool developed for a different population with cognitive impairments.

As implant-supported restorations have become very popular, there is a tendency to extract teeth and replace them with implants. However, the first goal of dentistry should always be the preservation of natural teeth, given the prerequisite that these can be maintained with the application of appropriate treatment modalities. Therefore, individual tooth risk assessment and prognosis are very important in the treatment plan process.

Article Synopsis
  • Bone homeostasis involves EphB2 and EphB3 receptors in mesenchymal stromal/stem cell differentiation into bone tissue.
  • In vitro studies show that EphB3-/- MSCs express more osteogenic factors while EphB2-/- MSCs lean towards fat cell differentiation.
  • In vivo experiments with mouse models indicate that EphB3 deficiency protects against bone loss by maintaining higher levels of osteoprogenitor and preosteoblast cells, highlighting its role as a negative regulator of bone differentiation.

Plant growth occurs via the interconnection of cell growth and proliferation in each organ following specific developmental and environmental cues. Therefore, different photoperiods result in distinct growth patterns due to the integration of light and circadian perception with specific Carbon (C) partitioning strategies. In addition, the TARGET OF RAPAMYCIN (TOR) kinase pathway is an ancestral signaling pathway that integrates nutrient information with translational control and growth regulation.

Using a cross-sectional survey study with undergraduate students ( = 1257; age = 20; 908 women) in the United States, this paper examined college students' use of social media for coping and its association with COVID-19-related worries (loneliness, interpersonal stress, anxiety) and mental health outcomes (depression, generalized anxiety, and life satisfaction). Undergraduate students were found to use social media frequently during the pandemic to socially connect with others online and to modulate negative emotions. Structural equation modeling revealed that COVID-19-related worries were positively related to social media use for coping and that coping using social media was negatively related to general mental health concerns (depression, generalized anxiety) and positively associated with general mental health wellness (i.

Background: Among all studies describing COVID-19 clinical features during the first wave of the pandemic, only a few retrospective studies have assessed the correlation between olfac-tory dysfunction (OD) and the evolution of disease severity. The main aim was to assess whether OD is a predictive factor of COVID-19 severity based on the patient's medical management (outpa-tient care, standard hospital admission, and ICU admission).

Methods: A national, prospective, mul-ticenter cohort study was conducted in 20 public hospitals and a public center for COVID-19 screen-ing.
