Smith-Lemli-Opitz syndrome (SLOS) is an autosomal recessive multiple congenital malformation and intellectual disability syndrome resulting from variants in DHCR7. Auditory characteristics of persons with SLOS have been described in limited case reports but have not been systematically evaluated. The objective of this study is to describe the auditory phenotype in SLOS. Age- and ability-appropriate hearing evaluations were conducted on 32 patients with SLOS. A subset of 21 had auditory brainstem response testing, from which an auditory neural phenotype is described. Peripheral or retrocochlear auditory dysfunction was observed in at least one ear of 65.6% (21) of the patients in our SLOS cohort. The audiometric phenotype was heterogeneous and included conductive, mixed, and sensorineural hearing loss. The most common presentation was a slight to mild conductive hearing loss, although profound sensorineural hearing loss was also observed. Abnormal auditory brainstem responses indicative of retrocochlear dysfunction were identified in 21.9% of the patients. Many were difficult to test behaviorally and required objective assessment methods to estimate hearing sensitivity. Individuals with SLOS are likely to have hearing loss that may impact communication, including speech and language development. selleck kinase inhibitor Routine audiologic surveillance should be conducted to ensure prompt management of hearing loss.
This study investigated the role of oral health self-perception as mediator of association between dental caries and depression among pregnant women from the 2015 Pelotas Birth Cohort Study, Brazil.

Overall, 2,496 pregnant women participated of this oral health sub-study. Data related to demographic and socioeconomic conditions, lifetime and current depression, and oral health self-perception were collected. Participants were also assessed for dental caries (DMF-T index). Depression was assessed using the Edinburgh Postnatal Depression Scale. For analysis, six outcomes related to dental caries experience were considered. Causal mediation analysis was performed using parametric regression models.

When it was assumed that all subjects had poor perception about oral health, it was observed that the presence of moderate/severe depressive signals and symptoms was higher in subjects with dental caries experience (OR 1.13; CI 95% 1.06-1.20), with severity of untreated dental caries (OR 2.08; CI 95% 1.16-3.78), untreated dental caries (OR 1.18; 95% CI 1.07-1.29), tooth loss (OR 1.08; 95% CI 1.02-1.14), and filled tooth (OR 1.07; 95% CI 1.02-1.16).

Our findings show the effect of dental caries on depression is mediated by self-perception about oral health in pregnant women.

In this respect, a series of linear dicarboxylic acids were deliberately installed in the prototype MOF, LIFM-28, leading to a dramatically increased pore volume (from 0.41 to 0.82 cm3  g-1 ) and reduced pore size (from 11.1×11.1 Å2 to 5.6×5.6 Å2 ). The increased pore volume endows the multifunctional MOFs with much higher ethane adsorption capacity, especially for LIFM-63 (4.8 mmol g-1 ), representing nearly three times as much ethane as the prototypical counterpart (1.7 mmol g-1 ) at 273 K and 1 bar. Meanwhile, the reduced pore size imparts enhanced ethane/ethylene selectivity of the multifunctional MOFs. Theoretical calculations and dynamic breakthrough experiments confirm that the DSI is a promising approach for the rational design of multifunctional MOFs for this challenging task.The LIF-JAK2-STAT3 pathway is the central signal transducer that maintains undifferentiated mouse embryonic stem cells (mESCs), which is achieved by the recruitment of activated STAT3 to the master pluripotency genes and activation of the gene transcriptions. It remains unclear, however, how the epigenetic status required for the master gene transcriptions is built into LIF-treated mESC cultures. In this study, Jak2, but not Stat3, in the LIF canonical pathway, establishes an open epigenetic status in the pluripotency gene promoter regions. Upon LIF activation, cytosolic JAK2 was translocalized into the nucleus of mESCs, and reduced DNA methylation (5mC levels) along with increasing DNA hydroxymethylation (5hmC) in the pluripotent gene (Nanog/Pou5f1) promoter regions. In addition, the repressive histone codes H3K9m3/H3K27m3 were reduced by JAK2. Activated JAK2 directly interacted with the core epigenetic enzymes TET1 and JMJD2, modulating its activity and promotes the DNA and histone demethylation, respectively. The JAK2 effects were attained by tyrosine phosphorylation on the epigenetic enzymes. The effects of JAK2 phosphorylation on the enzymes were diverse, but all were merged to the epigenetic signatures associated with open DNA/chromatin structures. Taken together, these results reveal a previously unrecognized epigenetic regulatory role of JAK2 as an important mediator of mESC maintenance.Porcine circovirus 4 (PCV4), a novel and unclassified member of the genus Circovirus, was first reported in China in 2019. Aiming to provide more evidence about the active circulation of PCV4, this study screened 335 pooled internal organs and detected the virus (i) at a rate of 3.28%, (ii) from both clinically healthy and clinically sick pigs of various age groups, and (iii) in six out of nine provinces of Korea. The complete genomic sequence of the Korean PCV4 strain (E115) was 1,770 nucleotides in length and had 98.5%-98.9% identity to three PCV4 strains currently available at GenBank. Utilizing a set of bioinformatic programs, it was revealed that the Korean PCV4 strain contained several genomic features of (i) a palindrome stem-loop structure with a conserved nonanucleotide, (ii) packed overlapping ORFs oriented in different directions and (iii) two intergenic regions in between genes encoding the putative replication-associated protein (Rep) and capsid (Cap) proteins. This study also predicted the presence of essential elements for the replication of circoviruses in all PCV4 strains, for example the origin of DNA replication, endonuclease and helicase domains of Rep, and the nuclear localization signal on the putative Cap protein.
