<b>Introduction</b> Upon hearing that the "little" patient has trouble with hearing, we are mostly interested in the level of his hearing threshold. When the child is in the first year of life, results can only be achieved by means of ABR test. Subsequent control tests, especially in children from the hearing loss risk groups selected in this study, show that the obtained outcomes are subject to fluctuations. Their fluctuating nature is manifested by the instability of wave V threshold in subsequent diagnostic periods. Such variability often delays the implementation of the appropriate proceeding. Knowledge of the dissimilarity of behavior of the wave V threshold occurring in individual groups at risk of hearing loss allows for the correct interpretation of the obtained results, and thus, effective therapeutic measures. <br><b>Aim</b> The aim of the paper is to analyze the stability of wave V threshold during the first year of life in children from selected risk groups for congen.<b>Introduction</b> Preoperative imaging, besides audiological evaluation, plays a major role in evaluation of candidacy for auditory implants, and in particular cochlear implants. It is essential to assess whether the basic criteria necessary for implantation are met. Diagnostic imaging is crucial not only in determining candidacy, but also determining the feasibility of cochlear implantation as it allow to anticipate surgical difficulties which could preclude or complicate the implantation of the device. The aim of the study is to present the protocol for the evaluation of preoperative imaging studies with particular focus on the factors potentially affecting clinical decisions in children qualified for cochlear implantation. <br><b>Material and method</b> Preoperative imaging studies of 111 children performed prior to cochlear implantation were analyzed high-resolution computed tomography (HRCT) of temporal bones and MRI. The assessment was made according to the presented protmplantation. Inner ear malformations and cochlear ossification following meningitis are relatively frequently encountered in children qualified for a cochlear implant.Homologous recombination is an important source of biological genetic variation. Limited by detection methods, there are only a few reports on the homologous recombination in high plants and its product - heteroduplex DNA (hDNA). In the present study, applying the strategy of detecting hDNA by constructing populations from inhibited post-meiotic segregation, two hybrid triploid populations were constructed from two maternal parents inPopulus tomentosa by inhibiting post-meiotic segregation. One hundred and ten simple sequence repeat (SSR) markers were used to study the occurrence and variation of hDNA on nine chromosomes inP. tomentosa with different genotypes. The results showed that the frequencies of hDNA between two female parents inP. tomentosa ranged from 8.5% to 87.2%. The hDNA frequency was positively correlated to the distance from the centromere, but the average hDNA frequency on a chromosome had no correlation with the chromosome length. One to 3 times recombination events were detected on most chromosomes, and only a few four- or five-times recombination events were detected. The overall frequencies of hDNA on the same chromosome in two genotypic individuals were roughly similar, while the hDNA frequencies varied greatly at specific SSR loci. Compared withTacamahaca poplar hybrid,P. pseudo-simonii × P. nigra 'Zheyin3#', detection of homologous recombination times and the frequency and location of hDNA were largely different. This study is the first to describe the characteristics and variations of homologous recombination inP. tomentosa with two different genotypes, which will provide valuable insights for exploring the characteristics and variations of homologous recombination among interspecies and intraspecies in higher plant.Inflammatory bowel disease (IBD) has emerged as a public health challenge with high incidence, recurrence rates and low cure rate. Moreover, sustained inflammation increases the risk of colorectal cancer. The occurrence and progression of IBD are closely related to the genetic mutation. Previous genome-wide association studies (GWAS) analysis demonstrated that the susceptibility loci rs4676410, rs3749171, and rs3749172 in theGPR35 gene locus increase the risk of IBD, but no direct evidence on the function ofGPR35 in IBD progression has been shown. B022 chemical structure To investigate the role ofGPR35 in IBD, CRISPR/Cas9 technology was employed to construct aGpr35 knockout mouse strain. TheGpr35-/- mice exhibited lower susceptibility to dextran sodium sulfate-induced IBD model than the wildtype group with a significant reduction in body weight loss, DAI score, intestinal epithelial injury, and macrophage cell infiltration. To explore how the IBD susceptibility loci rs3749171 and rs3749172 regulate GPR35 activity, two mutant forms of GPR35 (T108M and S294R) were constructed. By analyzing the activity of GPR35 downstream signaling pathway, the two mutation forms of GPR35 exhibited higher receptor activity to Zaprinast than the wildtype GPR35. Finally, the Western blotting analysis found an elevated phosphorylation level of ERK1/2 inGpr35-/- colon epithelial after DSS treatment, demonstrating that the loss function ofGpr35 alleviates the IBD syndrome by activating the ERK1/2 signaling pathway. In summary, the IBD susceptibility loci rs3749171 and rs3749172 may promote the disease progression by activating GPR35 activity, providing a potential drug target for the treatment of inflammatory bowel disease.Spinal muscular atrophy (SMA) is a common childhood neuromuscular disease inherited in an autosomal recessive pattern. The majority of SMA patients have a homozygous deletion of survival motor neuron 1 (SMN1) gene. As a special SMA carrier, the (2+0) genotype ofSMN1 poses a great challenge for carrier screening and family genetic counseling. A previous study showed that polymorphisms of g.27134 T>G and g.27706_27707delAT had a predictive effect on (2+0) carriers in the Ashkenazi Jewish population. To further explore whether these two polymorphisms are specific to the Chinese population, the present study recruited 44 family members and 204 controls with knownSMN1copy number. These 44 family members were from nine unrelated SMA families withSMN1 homozygous deletion, and one of the proband parents was suspected to be a (2+0) carrier. Multiplex ligation-dependent probe amplification (MLPA) and short tandem repeat (STR) linkage analyses were used to determine the (2+0) genotype and polymorphism screening. Finally, by analyzing theSMN copies and haplotype from three generations of family members and two generations of multi-child families, ten individuals in nine families were confirmed as (2+0) carriers.
