Therapeutic Implications of Narrow Band Ultraviolet B on Psoriasis Severity and Serum Levels of Acute Phase Reactants
Abstract Acute phase reactants (APR) are proteins that had been associated with psoriasis severity. We aimed to evaluate the association between psoriasis disease severity and some inflammatory markers as (CRP, ESR and fibrinogen) before and after narrow band ultraviolet NB (NB‐UVB) therapy. The present study included 38 psoriatic patients and 38 controls of matching age and sex. The 38 included patients were divided according to their pre‐treatment PASI score into 2 subgroups: moderate 13 (34.2%)...

Implication of COVID‐19 in oral oncology practices in Brazil, Canada and the United States
Abstract The newly emerged Coronavirus disease 2019 (COVID‐19) is an infectious disease that has spread rapidly throughout the world. The most common signs and symptoms are fever, dry cough and shortness of breath which can progress to severe viral pneumonia and multi‐organ failure in susceptive patients (Chen et al. 2020, Wang et al. 2020). Droplet transmission and person‐person transmission appear to be the main route of transmission of COVID‐19, however asymptomatic patients are also carriers...

A simple tool to a complex reality – WhatsApp use in a developing country during COVID‐19 pandemic
Abstract The consequences of the SARS‐CoV‐2 pandemic has significantly affected dental practice. Since dental care is considered a high‐risk activity (Volgenant et al., 2020), public and private dental clinics are closed to non‐urgent cases in many countries. Several new routines and practices have been proposed to reduce this risk in dental offices, but standard dental treatment is expected to happen only after the “first wave” of disease and on an entirely new basis.

Geographic patterns in colonial reproductive strategy in Myrmecina nipponica: links between biogeography and a key polymorphism in ants
Abstract The ability to express different phenotypes can help define species distributions by allowing access to, and exploitation of, new environments. Social insects employ two markedly different reproductive strategies with contrasting cost/benefit characteristics: independent colony foundation (ICF), which is associated with high dispersal range and high risk, and dependent colony foundation (DCF), characterized by low risk but low dispersal. The ant Myrmecina nipponica employs both of these...

Antagonistic interactions subdue inter‐species green‐beard cooperation in bacteria
Abstract Cooperation can be favored through the green‐beard mechanism, where a set of linked genes encodes both a cooperative trait and a phenotypic marker (green beard), which allows carriers of the trait to selectively direct cooperative acts to other carriers. In theory, the green‐beard mechanism should favor cooperation even when interacting partners are totally unrelated at the genome level. Here, we explore such an extreme green‐beard scenario between two unrelated bacterial species – Pseudomonas...

Increased Expression of PD‐1 and PD‐L1 in Patients With Laryngotracheal Stenosis
Objectives Laryngotracheal stenosis (LTS) is a fibrotic condition of the upper airway. Recent evidence suggests dysregulated host immunity plays a role in LTS development and progression. The programmed death‐1 (PD‐1)/programmed death‐ligand 1 (PD‐L1) axis, targeted by paradigm‐shifting immunotherapies for cancer treatment, has also recently been implicated in the pathogenesis of fibrotic pulmonary disease. However, a role for the PD‐1/PD‐L1 axis in the proximal airway fibrosis seen in LTS patients...

Somatostatin receptor expression and patients’ response to targeted medical treatment in pituitary tumors: evidences and controversies
Abstract Background Somatostatin receptors (SSTs) are widely co-expressed in pituitary tumors. SST2 and SST5 are the most represented SST subtypes. First-generation somatostatin receptor ligands (SRLs) mainly target SST2, while pasireotide, a multi-receptor ligand, shows high binding affinity for both SST5 and SST2. Therefore, SRLs are routinely used as medical treatment for GH-, TSH-, and ACTH-secreting pituitary tumors. ...
