Enzymes catalyze reactions by binding and orienting substrates with dynamic interactions. Horse liver alcohol dehydrogenase catalyzes hydrogen transfer with quantum-mechanical tunneling that involves fast motions in the active site. The structures and B factors of ternary complexes of the enzyme with NAD+ and 2,3,4,5,6-pentafluorobenzyl alcohol or NAD+ and 2,2,2-trifluoroethanol were determined to 1.1-1.3 Å resolution below the `glassy transition' in order to extract information about the temperature-dependent harmonic motions, which are reflected in the crystallographic B factors. The refinement statistics and structures are essentially the same for each structure at all temperatures. The B factors were corrected for a small amount of radiation decay. The overall B factors for the complexes are similar (13-16 Å2) over the range 25-100 K, but increase somewhat at 150 K. Applying TLS refinement to remove the contribution of pseudo-rigid-body displacements of coenzyme binding and catalytic domains provided residual B factors of 7-10 Å2 for the overall complexes and of 5-10 Å2 for C4N of NAD+ and the methylene carbon of the alcohols. These residual B factors have a very small dependence on temperature and include local harmonic motions and apparently contributions from other sources. Structures at 100 K show complexes that are poised for hydrogen transfer, which involves atomic displacements of ∼0.3 Å and is compatible with the motions estimated from the residual B factors and molecular-dynamics simulations. At 298 K local conformational changes are also involved in catalysis, as enzymes with substitutions of amino acids in the substrate-binding site have similar positions of NAD+ and pentafluorobenzyl alcohol and similar residual B factors, but differ by tenfold in the rate constants for hydride transfer.The recombination directionality factors from Mesorhizobium spp. (RdfS) are involved in regulating the excision and transfer of integrative and conjugative elements. Here, solution small-angle X-ray scattering, and crystallization and preliminary structure solution of RdfS from Mesorhizobium japonicum R7A are presented. RdfS crystallizes in space group P212121, with evidence of eightfold rotational crystallographic/noncrystallographic symmetry. Initial structure determination by molecular replacement using ab initio models yielded a partial model (three molecules), which was completed after manual inspection revealed unmodelled electron density. The finalized crystal structure of RdfS reveals a head-to-tail polymer forming left-handed superhelices with large solvent channels. Additionally, RdfS has significant disorder in the C-terminal region of the protein, which is supported by the solution scattering data and the crystal structure. The steps taken to finalize structure determination, as well as the scattering and crystallographic characteristics of RdfS, are discussed.S1 nuclease from Aspergillus oryzae is a single-strand-specific nuclease from the S1/P1 family that is utilized in biochemistry and biotechnology. S1 nuclease is active on both RNA and DNA but with differing catalytic efficiencies. This study clarifies its catalytic properties using a thorough comparison of differences in the binding of RNA and DNA in the active site of S1 nuclease based on X-ray structures, including two newly solved complexes of S1 nuclease with the products of RNA cleavage at atomic resolution. Conclusions derived from this comparison are valid for the whole S1/P1 nuclease family. For proper model building and refinement, multiple lattice-translocation defects present in the measured diffraction data needed to be solved. Two different approaches were tested and compared. Correction of the measured intensities proved to be superior to the use of the dislocation model of asymmetric units with partial occupancy of individual chains. As the crystals suffered from multiple lattice translocations, equations for their correction were derived de novo. The presented approach to the correction of multiple lattice-translocation defects may help to solve similar problems in the field of protein X-ray crystallography.An introduction to the Proceedings of the 2020 CCP4 Study Weekend on model building which are available as a virtual issue at https//journals.iucr.org/special_issues/2020/CCP42020/.
To assess the knowledge level and awareness of Alzheimer's disease, including knowledge about the disease, pharmacotherapy, provision of patient education and associated factors among community pharmacists across Turkey and Northern Cyprus.

This was a descriptive, cross-sectional study conducted among community pharmacists working in Turkey (Group A) and Northern Cyprus (Group B). Disease and pharmacotherapy knowledge of AD were assessed using AD Knowledge Scale (ADKS), and drug treatment (KADT) scale, respectively.

Both groups reported a moderate level of knowledge of AD, especially medically-oriented domains, with no significant difference regarding the mean ADKS domains (18.8 ± 2.8 vs. 18.9 ± 3.4;
 = .98). Nevertheless, participants from both groups reported a good level of KADT knowledge about AD treatment (
 = .03). Group A reported a statistically significant higher level of knowledge about drug interactions compared with Group B (54.6% vs. 45.8%;
 = .01), and knowledge about proper information (79.6% vs. CFSE ic50 31.8%;
 = .02). There was a statistically significant KADT difference correlated with gender, those having a Master degree, more than 5 years of work experience, and those taking AD training courses.

There is still a lack of knowledge regarding AD reported by moderate ADKS score, especially in medically-oriented domains, which creates a barrier to early provision of care and preventing AD, noted with no difference among community pharmacists across Turkey and Northern Cyprus.

Mobilising insights from labelling theory's accounts of stigma and recovery, in conjunction with critical and feminist disability theory's attention to emotional and physical pain, we suggest that a feminist psychiatric disability approach to NSSID can illuminate the limits of a fully demedicalised engagement with self-injury. While remaining critical of psychiatrisation processes, we explore the implications of 'strategic (dis)identifications' with illness labels as mechanisms through which to manage and access care, treatment and recovery. Such a nuanced account engenders more deeply material considerations of pain, stigma, treatment and 'cure' at the site of NSSID, opening new avenues of engagement with self-injury for sociologists and critical disability scholars alike.Bisphenol A (BPA) exposure may be positively associated with cardiovascular disease (CVD). For more than a past decade, exposure to bisphenol F (BPF) and bisphenol S (BPS), as substitutes for BPA, has gradually increased in the population. Whether BPF and BPS exposure are associated with CVD remains unclear. We used data from the United States National Health and Nutrition Examination Survey (NHANES) from 2013 to 2016. A total of 3,502 participants, including 368 with CVD, were enrolled in the final analysis. Associations of BPA, BPF and BPS with CVD were determined using multivariate logistic regression analysis. The highest level of urinary BPA (≥2.5 ng/ml) was significantly associated with a higher CVD prevalence (odds ratio [OR], 1.58; 95% confidence interval [CI], 1.08-2.3) among all participants in the quartile analysis. In stratified analyses, the highest level of urinary BPA was positively associated with CVD prevalence in males (1.86, 1.1-3.13) and the elderly population (≥60 years old) (1.89, 1.2-2.97). Higher levels of urinary BPF were positively associated with CVD prevalence in females (Q2 1.81, 1.03-3.18; Q4 1.73, 1.07-2.79) and in the elderly population (Q3 1.7, 1.16-2.48). No associations were found between urinary BPS levels and CVD, regardless of whether the participants were stratified by age or sex. In conclusion, exposure to BPA or BPF was positively correlated with CVD prevalence, but an association was not found for exposure to BPS. BPF may not be as safe as assumed for human health.
There are different approaches to breastfeeding interventions, but the global 6-month exclusive breastfeeding rates remain suboptimal. The COVID-19 pandemic has brought extra difficulties in promoting breastfeeding.

To test the feasibility and effectiveness of a theory-based, real-time online educational and support program for breastfeeding related outcomes.

An assessor-blinded, prospective pilot randomized controlled trial with parallel-group, repeated-measures design was used. The sample was low-risk primiparous mothers (
= 40) who delivered in the local public hospitals. Study outcomes consisted of exclusive breastfeeding rate, breastfeeding self-efficacy, and other breastfeeding outcomes measured by a self-reported questionnaire, including the Breastfeeding Self-Efficacy Scale and the Edinburgh Postnatal Depression Scale. Comparisons between the differences in the intervention and control groups were carried out.

Thirteen participants in the intervention group successfully completed the programdy outcomes. Considering the participants' comments, we suggest refining and further testing the intervention with a larger sample size over a longer-term follow-up to confirm its effectiveness.This study has been registered at ClinicalTrials.gov (NCT04741425).The group of 18 new amide derivatives of mycophenolic acid (MPA) and selected heterocyclic amines was synthesised as potential immunosuppressive agents functioning as inosine-5'-monophosphate dehydrogenase (IMPDH) uncompetitive inhibitors. The synthesis of 14 of them employed uronium-type activating system (TBTU/HOBt/DIPEA) while 4 of them concerned phosphonic acid anhydride method (T3P/Py) facilitating amides to be obtained in moderate to excellent yields without the need of phenolic group protection. Most of optimised protocols did not require complicated reaction work-ups, including chromatographic, solvent-consuming methods. The biological activity assay was performed on the T-Jurkat cell line and peripheral mononuclear blood cells (PBMCs) which are both dedicated for antiproliferative activity determination. Each of designed derivatives was characterised by reduced cytotoxicity and benzoxazole analogue (A2) revealed the most promising activity. Subsequently, an observed structure-activity relationship was discussed.
Total knee arthroplasty (TKA) is associated with severe postoperative pain. Multimodal analgesia, including peripheral nerve block, is recommended for post-operative pain relief. Administration of some pain medications prior to surgery has shown to be more effective than after the operation. This is a prospective, randomized controlled trial designed to compare the analgesic efficacy of the adductor canal block (ACB) performed immediately before or immediately after primary total knee arthroplasty (TKA). We hypothesized that ACB before the surgery will reduce postoperative pain and improve knee function.

A total of 50 patients were enrolled and randomized into 2 groups, with 26 patients receiving a preoperative ACB and 24 receiving a postoperative ACB.

Treatment groups were similar in terms of gender (
= .83), age (
= 0.61) weight (
= .39) and ASA score. Average visual analogue scale (VAS) on arrival to the post-anesthesia care unit (PACU) were 4.9 ± 3.2 in the preoperative ACB versus 3.4 ± 2.8 for the postoperative ACB (
