Behavioural and brain lateralization is widespread among non-human vertebrates. Motor lateralization has been investigated in the domestic dog, revealing that "pawedness" in this species seems to be sex and task related; however, few if any studies considered this asymmetry in wolves (Canis lupus). The aim of this study was to investigate the paw preference of seven wolves housed at Parco Natura Viva - Italy, during the interaction with food-related (FD) and olfactory (OLF) environmental enrichment devices. Eleven sessions were done (22 session in total) per condition (FD and OLF), and data about enrichment manipulation were collected. Most of the wolves manipulated the enrichment devices using one paw rather than both paws. At the individual level, all subjects were lateralized in paw use, six were right pawed, one was left pawed (the alpha male) regardless of the enrichment condition. The fact that one paw rather than both was frequently involved in manipulation could indicate a practical advantage for each individual in being lateralized in paw use. Despite the small sample size, our results provide interesting insights about lateralization in wolves, deserving further investigations. More studies are needed considering factors such as temperament, social rank and task complexity on canid motor lateralization.The 3D structure analysis for Muga silk protein was predicted through homology modeling and Ramachandran plot with the determination of quality index for Stereo/packing and 3D quality index. Silk Nanoparticles were synthesized using conventional desolvation and microwave-assisted radiolysis method from Muga silk fibroin. The secondary structure evolution due to two different synthesis methods was investigated using FTIR and Circular Dichroism (CD) spectroscopy. The microwave synthesized nanoparticles showed enhanced β-sheet content than desolvation synthesized nanoparticles. The conformational changes of Muga silk fibroin protein to nanoparticle followed an ordered transition from random coil to α-helix then from α-helix to β-turn and from β-turn to β-sheets where α-helix and β-turn are the intermediate forms before getting stabilized to the metastable β-sheets structure. The thermodynamics involved in secondary structure evolution was studied from CD analysis and activation energy involved in the formation of the secondary structure was determined.

In this study, calf thymus deoxyribonucleic acid (CT-DNA) binding of zinc-naproxen complex, [Zn(naproxen)2(MeOH)2], at physiological pH has been investigated by multi-spectroscopic techniques and molecular docking. Zinc-naproxen complex displays significant binding property to the CT-DNA (Kb = 0.2  ×  105 L.mol-1). All of the experimental results; relative increasing in viscosity of CT-DNA and fluorimetric studies using ethidium bromide (EB) and Hoechst 33258 probes, are indicative of groove binding mode of zinc-naproxen complex to CT-DNA. These results show that the coordination of naproxen to zinc metal switches the mode of binding from intercalation to groove. The molecular modeling also shows that the complex binds to the AT-rich region of minor groove of DNA. Structural and topography changes of DNA in interaction with the complex by atomic force microscopy (AFM) indicated that CT-DNA becomes swollen after interaction. The pUC18 plasmid DNA cleavage ability of zinc-naproxen complex by gel electrophoresis experiments revealed that zinc-naproxen complex cleaved supercoiled pUC18 plasmid DNA to nicked DNA. The cytotoxicity of the zinc complex performed by MTT method on HT29 and MCF7 cancer cell lines and on HEK 293 normal cell lines indicates that zinc complex has no cytotoxic effect on both HT29 and MCF7 cell lines but has better cytotoxicity effect on HEK 293 cell lines compared to cisplatin standard drug. The antimicrobial activity of the complex against Staphylococcus aureus and Escherichia coli bacteria revealed the high antimicrobial activity of the complex. Communicated by Ramaswamy H.

O6-Benzylguanine In the first case study, a 14-day repeat-dose study evaluating an anti-thymic stromal lymphopoietin (anti-TSLP) dAb resulted in minimal mononuclear inflammatory cell infiltrates in the lungs, increases in lymphocytes in bronchoalveolar lavage fluid, and development of antidrug antibodies (ADAs). In a 6-week inhalation study, there was an increase in incidence and/or severity of mononuclear cell infiltrates in the lung, increased cellularity in the tracheobronchial lymph node (TBLN), and development of ADA. The second case study evaluated a change in duration of inhalation dosing, a different route of exposure (intravenous or IV), and recovery following an off-dose period with an anti-tumor necrosis factor receptor 1 dAb. A 7-day repeat-dose inhalation study and a 14-day IV study produced no microscopic effects in the lung, whereas a 14-day inhalation study resulted in moderate increases in pulmonary perivascular/peribronchiolar/alveolar lymphocytic infiltrates and increased cellularity in the TBLN, with partial and full recovery, respectively, after 14 days. The lung and lymph node findings seen after inhalation of either dAb were considered secondary to the immunogenic response to a human protein and were considered nonadverse.

There is insufficient evidence about the ability of pretransplant psychosocial evaluations to predict posttransplant outcomes. While standardized assessments were developed to increase predictive validity, it is unclear whether the risk scores they yield predict outcomes. We investigated if the Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT), a scaling approach to those assessments, would have been a superior predictor than the standard psychosocial evaluation.

In this retrospective study, medical records of 182 adult liver transplant recipients who were at least 1 year posttransplant and prescribed tacrolimus for immunosuppression were analyzed. Regression analyses predicted outcomes of interest, including immunosuppressant nonadherence and biopsy-proven rejection, obtained 1-year posttransplant to time of data collection. Nonadherence was determined using the medication level variability index (MLVI).

Approximately 49% of patients had MLVI > 2.5, suggestive of nonadherence, and 15% experienced rejection. SIPAT total score did not predict adherence either using the continuous (P = .70), or dichotimized score, above or below > 2.5 (P = .14), or rejection (P = 0.87). Using a SIPAT threshold (total score > 69) did not predict adherence (p = .16) nor was a superior predictor of the continuous adherence score (P = .45), MLVI > 2.5 (P = .42), or rejection (P = 0.49), than the standard evaluation.

Our findings suggest that the SIPAT is unable to predict 2 of the most important outcomes in this population, immunosuppressant adherence and rejection. Research efforts should attempt to evaluate the best manner to use psychosocial evaluations.

Intravitreous administration of a novel biotherapeutic in a 14-week cynomolgus monkey study using insulin syringes was associated with 2, non-test-article-related phenomena "vitreous floater/clear sphere" on indirect ophthalmoscopy and intrascleral "foreign material near injection track" on histopathology. Retrospective analysis of 81 other preclinical studies of IVT administration of novel biotherapeutics found a greater frequency of clear spheres in monkey IVT studies using insulin syringes and formulations containing polysorbate. We were able to correlate microscopic findings of clear circular to oval areas in the sclera near the injection track with an energy-dispersive X-ray spectroscopy (EDS) signal for silicon at the same location in the sclera. These observations provide further evidence that silicone lubricant in insulin syringes/needles is the source of clear spheres noted in the vitreous and foreign material noted near the injection track in the sclera. Although considered inert and toxicologically insignificant, silicone deposition within the eye should form part of the risk-benefit equation in a clinical setting.

This paper describes barriers to engagement in the context of group activities attended by nursing home residents with dementia.

The goal is to clarify the presence and types of barriers to group activities for persons with dementia.

Therapeutic recreation staff (TRs) who conducted the group activities, and trained research observers (ROs) independently identified barriers occurring during group activity sessions through ratings and open-ended comments, which were analyzed via a mixed-method approach.

Barriers were related to specific participant, environmental, and group session characteristics. Most frequently noted barriers were participant-related, pertaining to apathy and challenging behavior. Noise was the most frequent environmental barrier. Overall, ROs reported more barriers than TRs, yet TRs reported the barrier of inappropriate topic more frequently than ROs.

The study suggests that the number and specific types of barriers are associated with negative engagement outcomes. Insight into these barriers is the first step toward addressing them and minimizing their effects.

Serebral silent ischemia is a complication of carotid stenting. If silent ischemia occurs 24 h later of carotid stenting, it called early serebral silent ischemia. The aim of this study was to evaluate the effect of heparin infusion on the prevention of early silent ischemia in patients who underwent carotid stenting.

We included 26 patients who underwent carotid stenting. Patients who had carotid stenting, we randomized into two groups. The first group of patients were given continuously heparin infusion a maximum of 20,000 units for 24 h, and screened the aPTT value each 6 h. The aPTT value aimed a range of 2-3 times to up baseline. The second group didn't take heparin infusion. Diffusion weighted magnetic resonance imaging (DWI-MRI) and gradient echo (GRE) sequences performed in all patients at the 24 h of carotid stenting.

Early serebral silent ischemia was detected by DWI-MRI in 13 (50%) of 26 patients who underwent carotid stenting. Seven (53.80%) of 13 patients whit early serebral silent ischemia did not receive heparin treatment, while 6 (46.20%) received heparin treatment. There was no symptomatic or asymptomatic acute hemorrhage in patients who treated with heparin.

In our study, the continuation of anticoagulant therapy for 24 h to prevent early silent ischemia was not statistically significant. Also there is no reduction for count of serebral silent ischemia between two groups. However, due to the small number of patients in the study, future studies are required with more patients.
