Motivation: Protein sequence alignment forms the basis for comparative modeling, the most reliable approach to protein structure prediction, among many other applications. Alignment between sequence families, or profile-profile alignment, represents one of the most, if not the most, sensitive means for homology detection but still necessitates improvement. We aim at improving the quality of profile-profile alignments and the sensitivity induced by them by refining profile-profile substitution scores.
Results: We have developed a new score that represents an additional component of profile-profile substitution scores. A comprehensive evaluation shows that the new add-on score statistically significantly improves both the sensitivity and the alignment quality of the COMER method. We discuss why the score leads to the improvement and its almost optimal computational complexity that makes it easily implementable in any profile-profile alignment method.
Availability And Implementation: An implementation of the add-on score in the open-source COMER software and data are available at https://sourceforge.net/projects/comer. The COMER software is also available on Github at https://github.com/minmarg/comer and as a Docker image (minmar/comer).
Supplementary Information: Supplementary data are available at Bioinformatics online.

Background: Variations in the circadian rhythm in older adults can negatively affect brain and cardiovascular health. As a consequence, poor cognitive functioning, an increase in the inflammatory response, alterations in sleep patterns, changes in mood and a decrease in motivation, energy and initiative are observed.
Method: We retrospectively examined the initial and final neuropsychological assessment of 250 MCI outpatients, 125 of whom had received daily 3-9 mg of a fast-release melatonin preparation p.

Introduction: Monoamine oxidase-B (MAO-B) inhibitors, as an add-on therapy to levodopa, are widely used in Parkinson's disease (PD). The effects of MAO-B inhibitors on quality of life remain unclear, and the aim of this systematic review and meta-analysis was to assess the efficacy and safety of MAO-B inhibitors on quality of life in different domains.
Methods: We searched PubMed, Embass, and Cochrane Library databases for randomized controlled trials of PD patients who were administered MAO-B inhibitors.

Background: Ritlecitinib demonstrated efficacy in a phase 2b trial of nonsegmental vitiligo.
Objective: To evaluate the efficacy and tolerability of ritlecitinib with add-on narrow-band UVB (nbUVB) phototherapy in patients with nonsegmental vitiligo.
Methods: Following a 24-week, placebo-controlled, dose-ranging period, patients received ritlecitinib 200mg for 4 weeks then 50mg for 20 weeks, with or without nbUVB phototherapy 2x/week.

Background: Evenamide, a glutamate modulator, is currently in phase 3 of development as add-on treatment to antipsychotics in patients with inadequate response or treatment-resistant schizophrenia. This study was designed to determine if patients with chronic schizophrenia inadequately responding to a second-generation antipsychotic would benefit from add-on treatment with evenamide at a dose of 30 mg bid.
Methods: Study 008A was a prospective, 4-week, randomized, double-blind, placebo-controlled study evaluating the safety, tolerability, and efficacy of oral doses of evenamide of 30 mg bid in patients with chronic schizophrenia treated at stable therapeutic doses of a second-generation antipsychotic.

Objective: To explore the efficacy and safety of Juan Bi Pill (JBP) in treatment of active rheumatoid arthritis (RA).
Methods: From February 2017 to May 2018, 115 participants from 4 centers were randomly divided into JBP group (57 cases) and placebo group (58 cases) in a 1:1 ratio using a random number table method. Participants received a dose of JBP (4 g, twice a day, orally) combined with methotrexate (MTX, 10 mg per week) or placebo (4 g, twice a day, orally) combined with MTX for 12 weeks.
