GH11 xylanases are commercially important enzymes for degradation of xylan fibers. We have identified the presence of nine non-conserved and five conserved salt bridges in GH11 xylanase from Bacillus pumilus SSP34. We have designed two sets of mutants viz., (1) substitution mutants in which non-conserved charged amino acid residues have been replaced with appropriate hydrophobic residues based on side chain occupancy and hydrophobicity and (2) deletion mutants where non-conserved charged residues have been deleted. The stability of the mutants has been evaluated in-silico by analyzing the contributions of non-covalent interactions like hydrophobic interaction clusters and salt bridges. The stability of the resultant mutants was evaluated using parameters such as radius of gyration, solvent accessible surface area, root mean square deviation, root mean square fluctuations and protein unfolding measurements using molecular dynamic simulations. The deletion of certain charged residues resulted in mutants having lowered radius of gyration and decreased surface areas. However, RMSD and RMSF measurements indicated lowered stability in comparison to substitution mutants. Of the substitution mutants, the SBM 3 was the most stable mutant as indicated by Rg, SASA, RMSF and simulated protein unfolding measurements. The major contributing factors for improved stability could be strengthening of hydrophobic interactions in the GH11 xylanase from B. pumilus. These in-silico stability measurements of salt bridge mutants may lead to better design of GH11 xylanases for commercial applications.Communicated by Ramaswamy H. Sarma.
Colon cancer (CC) is a commonly-diagnosed cancer resulting in considerable individual heath burden. This study explored the mechanism of long non-coding RNA FEZF1 antisense RNA 1 (FEZF1-AS1) in CC.
FEZF1-AS1, microRNA-149-3p (miR-149-3p) and forkhead box P3 (FOXP3) expression in CC tissues and cell lines were determined. The relationship between FEZF1-AS1 expression with clinicopathological characteristics and prognosis of CC patients was observed. Immune responses and Treg differentiation in serum were detected. After co-culture with sorted peripheral blood CD4
CD25
Tregs, HCT116 were transfected with sh-FEZF1-AS1 or miR-149-3p mimic, while LoVo cells transfected with Oe-FEZF1-AS1 or miR-149-3p inhibitor to explore their roles in cellular phenotypes of CC.
FEZF1-AS1 and FOXP3 expression increased while miR-149-3p expression decreased in CC. High FEZF1-AS1 level was connected with severer clinicopathological status and poorer prognosis in patients with CC. Immune responses and Treg differentiation were enhanced in serum of patients with CC. Cell proliferation, migration and invasion were enhanced and apoptosis was impaired in CC cells co-cultured with CD4

It is urgent to find an effective antiviral drug against pandemic caused by the severe acute respiratory syndrome (Sars-Cov-2), which increases global health concerns. As it can be expensive and time-consuming to develop specific antiviral drugs, reuse of FDA-approved drugs that provide an opportunity to rapidly distribute effective therapeutics can allow to provide treatments with known preclinical, pharmacokinetic, pharmacodynamic and toxicity profiles that can quickly enter in clinical trials. In this study, using the structural information of molecules and proteins, a list of repurposed drug candidates was prepared again with the graph neural network-based GEFA model. The data set from the public databases DrugBank and PubChem were used for analysis. Using the Tanimoto/jaccard similarity analysis, a list of similar drugs was prepared by comparing the drugs used in the treatment of COVID-19 with the drugs used in the treatment of other diseases. The resultant drugs were compared with the drugs used in lung cancer and repurposed drugs were obtained again by calculating the binding strength between a drug and a target. The kinase inhibitors (erlotinib, lapatinib, vandetanib, pazopanib, cediranib, dasatinib, linifanib and tozasertib) obtained from the study can be used as an alternative for the treatment of COVID-19, as a combination of blocking agents (gefitinib, osimertinib, fedratinib, baricitinib, imatinib, sunitinib and ponatinib) such as ABL2, ABL1, EGFR, AAK1, FLT3 and JAK1, or antiviral therapies (ribavirin, ritonavir-lopinavir and remdesivir).Communicated by Ramaswamy H.

Tectonin beta-propeller repeat containing 2 (TECPR2) gene plays an important role in autophagy which may affect the temperature sensation in animals. A missense mutation (XM_024981840.1c.3989 G > A p.Arg1330His) of the transcripts X4 in the bovine TECPR2 gene was identified. In this study, the c.3989 G > A variant in TECPR2 gene was genotyped in a total of 25 cattle breeds (520 individuals). CP-690550 in vivo Our results indicated that the frequency of A allele showed a decreasing pattern from southern cattle to northern cattle, while the frequency of G allele showed the opposite pattern, which was consistent with the climate distribution of China. Compared with the GG genotype, southern cattle carried more the AA and AG genotypes. Furthermore, the association results carried out that the frequencies of genotypes (GG, AG, AA) and the value of climate parameters (mean annual temperature (T), relative humidity (RH) and temperature humidity index (THI) were significantly correlated (p  A variant of TECPR2 gene was associated with the heat tolerance trait in Chinese cattle and the locus may be considered as a molecular marker for Chinese cattle breeding.Closeness, in the sense of inclusion of other in the self, has been found to be an important factor for relationship well-being, satisfaction and pair-bonding. link2 In the past ten years, the self-expansion theory has also been incorporated into sex research, although studies are still very scarce and not without limitations. The present research aimed at further elucidating the relevance of relational factors for couple's sexuality, and to clarify the role inclusion of other in the self plays for sexual satisfaction and sexual distress. A broadly representative sample of 3,046 men and women aged 18 to 75 was taken from the German Health and Sexuality Survey (GeSiD). Throughout analyses, inclusion of other in the self and love were positively related to sexual satisfaction. Furthermore, inclusion of other in the self was negatively related to how strongly someone was distressed by experiencing sexual problems. Closeness seems to have a compensatory role especially for women with sexual problems, protecting them from experiencing sexual distress. In future research, couple's sexual satisfaction should not be compartmentalized from relational aspects. Results clearly promote the Inclusion of Other in the Self Scale as an interesting tool for both research and treatment.All-trans retinoic acid-based differentiation therapies have succeeded in the treatment of acute promyelocytic leukemia, which is a rare subtype of acute myeloid leukemia (AML). Their clinical efficacy is negligible, however, for other subtypes of AML. Here, we showed that strobilurin derivatives, a well-established class of inhibitors of mitochondrial electron transport chain (ETC) complex III, possessed differentiation-inducing activity in AML cells. Impairment of mitochondrial ETC activity was involved in the differentiation effects of strobilurin derivatives, where reactive oxygen species generation appeared unnecessary. Conversely, strobilurin derivative-mediated differentiation was triggered by pyrimidine deficiency, which resulted from the inhibition of the mitochondrial-coupled dihydroorotate dehydrogenase enzyme. Moreover, strobilurin derivative-mediated pyrimidine depletion led to the activation of the Akt/mTOR cascade, which was required for the differentiation. Our study provided evidence that strobilurin derivatives may represent a novel class of differentiation-inducing agents for the treatment of AML.This study aimed to examine the effect of social exclusion on psychological well-being and suicide possibilities among people with physical disabilities. This descriptive and cross-sectional type study was conducted among people with physical disabilities who are members of the Association of Disabled People. Data were collected using the face-to-face interview method with the "Participant Information Form," "Social Exclusion Scale for the People with Disabilities," "Psychological Well-Being Scale," and "Suicide Probability Scale." It was found that the disabled people participating in the study experienced moderate social exclusion with a score of 72.35 + 31.53, a moderate level of well-being with a score of 34.79 + 16.80, and above a moderate level of suicidal ideation with a score of 78.58 + 9.85. Also, there was a negative moderate and significant relationship between social exclusion and psychological well-being (p less then 0.01; r -0.492), while there was a positive strong relationship between social exclusion and the possibility of suicide (p less then 0.01; r 0.518).Diaphanospondylodysostosis is an extremely rare, recessively inherited, perinatal lethal skeletal disorder associated with BMPER gene mutations. Clinically it is characterized by defects in costovertebral ossification, absent ribs, hypertelorism, short nose with depressed nasal bridge, low-set ears, and short neck. At the extraosseous level, the most frequent pathologic finding is nephroblastomatosis with multicystic kidneys. We present the case of a child of non-consanguineous parents who died at 2 months of age in our center. Autopsy showed a marked costovertebral ossification defect, perilobar nephrogenic rests and loss of white matter with periventricular leukomalacia. After genetic study, the diagnosis of diaphanospondylodysostosis was confirmed. A previously undescribed germinal mutation in the BMPER gene (c.576 + 2dupT) was found.Previous studies have shown that cognitive control demands and long-term memory interact in several ways. For example, trial-unique Stroop entities which consist of two perceptually distinct stimulus dimensions can enhance subsequent memory. link3 In the present study, we investigated whether this effect generalises to a flanker paradigm. In the study phase, 60 participants had to classify target pictures which were flanked by pictures that were either congruent or incongruent to the target with regard to the response categories, thus manipulating response-category conflict. Then we assessed recognition memory. The results showed that the response-category conflict enhanced subsequent memory for incongruent targets, implying an up-regulation of top-down control that fostered memory encoding. The results demonstrate that the beneficial memory effect of a response-category conflict generalises to a flanker task.
