RESUMO

The investigation of chiral supramolecular stacking is of essential significance for the understanding of the origin of homochirality in nature. Unlike structurally well-defined amphiphilic liposomes, it remains unclear whether the solvophilic segments of the amphiphilic block copolymer play a decisive role in the construction of asymmetric superstructures. Herein, insights are presented into the stacking patterns and morphological regulation in azobenzene-containing block copolymer assemblies solely by modulating the solvophilic chain length. The solvophilic poly(methacrylic acid) (PMAA) segments of different molecular weights could cause multi-mode chirality inversions involving stacking transitions between intra-chain π-π stacking, inter-chain H- and J-aggregation. Furthermore, the length of the solvophilic PMAA also affects the morphology of the chiral supramolecular assemblies; rice grain-like micelles, worms, nanofibers, floccules, and lamellae can be prepared at different solvophilic-solvophobic balance. The comprehensive mechanism is collectively revealed by utilizing various measurement methods, such as including circular dichroism (CD), small-angle X-ray scattering (SAXS), and wide-angle X-ray diffraction (WAXD). This study highlights the critical importance of fully dissolved solvophilic segments for the chiroptical regulation of the aggregated core, providing new insights into the arrangement of chiral supramolecular structures in polymer systems.

RESUMO

Delayed outcome is common in phase I oncology clinical trials. It causes logistic difficulty, wastes resources, and prolongs the trial duration. This article investigates this issue and proposes the time-to-event 3 + 3 (T3 + 3) design, which utilizes the actual follow-up time for at-risk patients with pending toxicity outcomes. The T3 + 3 design allows continuous accrual without unnecessary trial suspension and is costless and implementable with pretabulated dose decision rules. Besides, the T3 + 3 design uses the isotonic regression to estimate the toxicity rates across dose levels and therefore can accommodate for any targeted toxicity rate for maximum tolerated dose (MTD). It dramatically facilitates the trial preparation and conduct without intensive computation and statistical consultation. The extension to other algorithm-based phase I dose-finding designs (e.g., i3 + 3 design) is also studied. Comprehensive computer simulation studies are conducted to investigate the performance of the T3 + 3 design under various dose-toxicity scenarios. The results confirm that the T3 + 3 design substantially shortens the trial duration compared with the conventional 3 + 3 design and yields much higher accuracy in MTD identification than the rolling six design. In summary, the T3 + 3 design addresses the delayed outcome issue while keeping the desirable features of the 3 + 3 design, such as simplicity, transparency, and costless implementation. It has great potential to accelerate early-phase drug development.

RESUMO

Controlling the secondary phase in chiral liquid-crystalline (LC) polymers is of great importance since it transfers and amplifies molecular information to the macroscopic properties. However, the chiral superstructures of the LC phase are determined exclusively by the inherent configuration of the parent chiral source. Here, we report the switchable supramolecular chirality of heteronuclear structures by the untraditional command between common chiral "sergeant" units and various achiral "soldier" units. Different chiral induction pathways between sergeants and soldiers were observed for copolymer assemblies with mesogenic and non-mesogenic soldier units, demonstrating the formation of a helical phase independent of the absolute configuration of the stereocenter. In the presence of non-mesogenic soldier units, the classical SaS (Sergeants and Soldiers) effect in the amorphous phase was observed; whereas in a full LC system, bidirectional command of sergeants was activated in response to the phase transition. Meanwhile, a full spectrum of morphological phase diagrams including spherical micelles, worms, nanowires, spindles, tadpoles, anisotropic ellipsoidal vesicles, and isotropic spherical vesicles were successfully achieved. Such spindles, tadpoles, and anisotropic ellipsoidal vesicles have rarely been obtained previously from chiral polymer systems.

RESUMO

OBJECTIVE: Survivors of stroke often experience post-stroke sleep disorders (PSSDs), but pharmacotherapy risks adverse side effects. Transcranial magnetic stimulation (TMS) is potentially a nonpharmacotherapeutic option. This meta-analysis investigated the effects of rTMS to treat PSSD. METHODS: Databases were searched for randomized controlled trials (RCTs) of rTMS to treat PSSD, conducted in accordance with the PRISMA 2020 guidelines. Risk-of-bias assessments were performed using the Cochrane risk-of-bias tool. A meta-analysis of the following indexes was performed using RevMan 5.4 software: Pittsburgh sleep quality index; effective rate of sleep improvement; Hamilton Anxiety Rating Scale (for mood); and National Institute of Health Stroke Scale (NIHSS, stroke severity). Mean differences (MDs) and confidence intervals (CIs) were calculated. RESULTS: The meta-analysis included 17 RCTs, with 1411 patients overall. The indexes indicated that rTMS could improve the sleep quality, mood, and stroke severity of patients with PSSD: Pittsburgh sleep quality index (12 studies; MD = - 2.51, 95% CI [- 3.24, - 1.79], P < 0.00001); effective rate of sleep improvement (7 studies; MD = 4.03, 95% CI [2.43, 6.68], P < 0.0001); Hamilton Anxiety Rating Scale (2 studies; MD = - 4.05, 95% CI [- 4.77, - 3.32], P < 0.00001); and NIHSS (2 studies; MD = -2.71, 95% CI [- 3.36, - 2.06], P < 0.00001). CONCLUSION: The results suggest that rTMS may have positive effects on the sleep quality, mood, and stroke severity of patients with PSSD.

RESUMO

OBJECTIVES: To determine the effectiveness of computer-assisted cognitive rehabilitation in improving cognitive function in patients with post-stroke cognitive impairment. BACKGROUND: In recent years, computer-assisted cognitive rehabilitation has been accepted as a good substitute or supplement for traditional cognitive rehabilitation. Some clinical randomised controlled trials have been carried out, but no relevant systematic evaluations have been performed. Therefore, we conducted a systematic review of studies involving computer-assisted cognitive rehabilitation to provide evidence-based data for its promotion and application. METHODS: Nine databases (Cochrane Library, PubMed, Web of Science, Embase, OVID, Wanfang Data, CNKI, VIP and SinoMed databases) were systematically searched. Randomised controlled trials that assessed computer-assisted cognitive rehabilitation for patients with post-stroke cognitive impairment were included. Two reviewers appraised the risks of bias through the Cochrane Collaboration's tool and performed the meta-analysis, including the assessment of heterogeneity. We follow the PRISMA 2020 guidelines. RESULTS: Thirty-two studies comprising 1837 participants were included. Compared with conventional therapy alone, the addition of computer-assisted cognitive rehabilitation significantly improved the global cognition of patients, evaluated using the Montreal cognitive assessment, mini-mental state examination and Loewenstein occupational therapy cognitive assessment (p < .01 for all tests). The therapy also significantly improved activities of daily living, assessed using the Barthel index, modified Barthel index and functional independence measure (p < .05 for all tests). CONCLUSION: Computer-assisted cognitive rehabilitation significantly improved the cognitive function and activities of daily living of patients with post-stroke cognitive impairment. RELEVANCE TO CLINICAL PRACTICE: Computer-assisted cognitive rehabilitation can be a valuable technique for cognitive rehabilitation after stroke. It is advantageous for improving patient cognition and restoring the overall functional state of patients. Moreover, the research findings can provide suggestions and inspiration for researchers to implement the proposal, which is conducive to the design of more rigorous and high-quality randomised controlled trials.

RESUMO

OBJECTIVE: To systematically evaluate the effects of acupuncture in patients with unilateral spatial neglect (USN) after stroke. DATA SOURCES: Relevant English- and Chinese- language studies published until 12th February 2022, were retrieved from China National Knowledge Infrastructure (CNKI), Wanfang, China Scientific Journals Database (VIP), SinoMed, PubMed, Cochrane Library, Embase, Web of Science and OVID. REVIEW METHODS: Randomized controlled trials (RCTs) assessing the effects of acupuncture in patients with USN after stroke were included. Two researchers independently identified eligible studies and extracted the data. The methodological quality of the studies was evaluated using the Cochrane Handbook for Systematic Reviews of Interventions v5.1.0. RESULTS: Twelve studies (731 participants) were included. The meta-analysis found that compared with the control group, acupuncture increased MMSE, BI, MBI, and FMA scores and reduced the USN scores (all P < 0.05). These results indicated that acupuncture improved cognitive function, activities of daily living (ADLs), and motor function and relieved the degree of USN in patients with USN after stroke. CONCLUSION: Acupuncture could promote the rehabilitation of cognitive function, ADLs, and motor function and relieve the symptoms of USN in patients with USN after stroke. It may be a good complementary treatment to rehabilitation therapy for USN.

RESUMO

The p16INK4A is a multifunction gene that includes regulation of the cell cycle, apoptosis, senescence and tumor development. However, the effects of p16 in hydroquinone-induced malignant transformation of TK6 cells remain unclear. The present study aimed to explore whether p16 loss facilitate malignant transformation in TK6 cells. The results demonstrated that p16/Rb signal pathway was suppressed in hydroquinone-induced malignant transformation of TK6 cells. We further confirmed that p16 loss stimulated cell proliferation, and accelerated cell cycle progression in vitro and in vivo. The immunoblotting analysis indicated that p16 regulated cell cycle progression via Rb and p53. Therefore, we conclude that p16 is involved in HQ-induced malignant transformation associated with suppressing Rb and p53 which resulting in accelerating the cell cycle progression.

RESUMO

A Gram-stain-negative and aerobic bacterial strain, designated as JL3514T, was isolated from surface water of the hydrothermal system around Kueishan Island. The isolate formed red colonies and cells were non-flagellated, rod-shaped and contained methanol-soluble pigments. Growth was observed at 10-50 °C (optimum, 30 °C), at pH 5.0-9.0 (optimum, pH 7.0) and in the presence of 0-9 % (w/v) NaCl (optimum, 2 %). Strain JL3514T was positive for catalase and weakly positive for oxidase. Results of 16S rRNA gene sequence analyses showed highest similarities to species in the family Erythrobacteraceae, namely Croceibacterium atlanticum (96.1 %), Pelagerythrobacter marensis (96.0 %), Tsuneonella rigui (96.0 %) and Altericroceibacterium xinjiangense (96.0 %). Phylogenetic analysis based on core gene sequences revealed that the isolate formed a distinct branch with the related species and it had a lower average amino acid identity value than the suggested threshold for genera boundaries. The major fatty acids (>5 %) were summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c), summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c), C16 : 0, C17 : 1 ω6c, C14 : 0 2-OH and C12 : 0. The dominant polar lipids comprised diphosphatidylglycerol, sphingoglycolipid, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, glycolipid, two unidentified lipids and one unidentified phospholipid. The main respiratory quinones were ubiquinone-10 (95.7 %) and ubiquinone-9 (4.3 %). The DNA G+C content from the genome was 63.0 mol%. Based on the presented data, we consider strain JL3514T to represent a novel genus of the family Erythrobacteraceae, with the name Pseudopontixanthobacter vadosimaris gen. nov., sp. nov. The type strain is JL3514T (=KCTC 62623T=MCCC 1K03561T).

RESUMO

A Gram-stain-negative and facultatively anaerobic bacterial strain, designated GUOT, was isolated from surface water collected from the South China Sea. Cells were non-flagellate, yellow, non-spore-forming and rod-shaped. The 16S rRNA gene sequence comparisons with species in the genus Arenibacter showed that strain GUOT shares the highest similarity of 97.5 % with Arenibacter echinorum and Arenibacter palladensis. Average nucleotide identity and digital DNA-DNA hybridization values between strain GUOT and its related type strains were 77.1-78.4% and 20.8-26.2 % respectively. Growth of strain GUOT occurred at 15-50°C (optimum, 20-25°C), pH 5-7.5 (pH 6) and in media containing 0-7 % NaCl (optimum, 0-1 %). Cells contained methanol-soluble yellow-coloured pigments but flexirubin-type pigments were absent. The major fatty acids (>5 %) were iso-C17 : 0 3-OH, iso-C15 : 0, anteiso-C15 : 0, C16 : 0, summed feature 3, iso-C15 : 1 G and iso-C15 : 0 3-OH. The dominant polar lipids comprised phosphatidylethanolamine and some unidentified polar lipids. The main respiratory quinone was menaquinone-6. The DNA G+C content of strain GUOT was 40.1 %. Based on the presented data, we consider strain GUOT to represent a novel species of the genus Arenibacter, for which the name Arenibacter aquaticus sp. nov. is proposed. The type strain is GUOT (=KCTC 62629T=MCCC 1K03559T).

RESUMO

BACKGROUND: Cumulative clinical improvement and speed of improvement are important to psoriasis patients. OBJECTIVE: Compare cumulative benefits of biologics over 12 to 16 weeks in the treatment of moderate to severe psoriasis. METHODS: A systematic literature review identified phase III trial data on Psoriasis Area and Severity Index (PASI) responses for biologics during 12 and 16 weeks of treatment. Cumulative clinical benefit, measured by the area under the curve for PASI ≥75% improvement (PASI 75), ≥90% improvement (PASI 90), and 100% improvement (PASI 100), was compared using the network meta-analysis and Bayesian methodology on the relative probability of achieving percentage of maximum area under the curve. RESULTS: Among biologics approved for psoriasis treatment, anti-interleukin-17 biologics demonstrated consistently greater cumulative clinical benefits on PASI 75, PASI 90, and PASI 100 over the 12- or 16-week period than anti-interleukin-23 and other biologics. For biologics with 12-week data, ixekizumab and brodalumab showed greater cumulative benefits for PASI 75, PASI 90, and PASI 100 than secukinumab, followed by guselkumab, infliximab, adalimumab, ustekinumab, and etanercept. Ixekizumab showed greater cumulative benefits than all other biologics reporting 16-week data. LIMITATIONS: Recently approved biologics were not included. CONCLUSION: Ixekizumab (at 12 weeks and 16 weeks) and brodalumab (at 12 weeks) had greater cumulative clinical benefit than all of other biologics studied.

RESUMO

Due to its wide presence in apicomplexan parasites as well as high polymorphism and antigenic diversity, the variable merozoite surface antigen (VMSA) family in Babesia sp. has attracted increasing attention of researchers. Here, all the reported VMSA genes of Babesia spp. were obtained from GenBank, and multiple alignments were performed by using conserved regions to blast the Babesia orientalis genome database (unpublished data). Five MSA genes (named MSA-2a1, MSA-2a2, MSA-2c1, MSA-1, and MSA-2c2, respectively) were identified, sequenced, and cloned from B. orientalis, which were shown to encode proteins with open reading frames ranging in size from 266 (MSA-2c1) to 317 (MSA-1) amino acids. All the five proteins contain an MSA-2c superfamily conserved domain, with an identical signal peptide and glycosyl phosphatidyl inositol (GPI)-anchor for each of them. The five proteins were also predicted to contain B cell epitopes, with only three for BoMSA-2c1, the smallest protein in the BoVMSA family, while at least six for each of the others. Notably, BoMSA-2a1 has 2 identical copies, a specific phenomenon only present in B. orientalis. This research has determined the MSA genes of B. orientalis and provides a genetic basis for further research of functional genes in B. orientalis.

RESUMO

Ixodid ticks are ectoparasites responsible for the transmission of a large number of bacterial, viral, and protozoan pathogens to animals and humans. As long-term blood-pool feeders, the digestion of host blood is critical to their development as well as to the establishment of the sexual cycle of hemoparasites such as Babesia parasites, the agents of human and animal babesiosis. Previous studies have demonstrated that cysteine proteases are involved in blood digestion, embryogenesis, and pathogen transmission in other species of ticks, but their characteristics and functions are still unidentified in Haemaphysalis flava. Here, we describe the characterization of a cysteine protease HfCL from H. flava. We show that HfCL belongs to the L-like papain family of proteases, exhibits high expression in nymphs and adults, and localizes to both the midgut and salivary glands. Biochemical assays using purified recombinant enzyme reveal that rHfCL can hydrolyze the fluorogenic substrate Z-phe-Arg-MCA with optimal activity detected at pH 6. Furthermore, the short-term growth assay indicates that rHfCL can inhibit the intraerythrocytic development of Babesia microti and Babesia gibsoni in vitro.

RESUMO

Babesia gibsoni (B. gibsoni), an intracellular apicomplexan protozoan, poses great threat to canine health. Currently, little information is available about the B. gibsoni (WH58) endemic to Wuhan, China. Here, the mitochondrial (mt) genome of B. gibsoni (WH58) was amplified by five pairs of primers and sequenced and annotated by alignment with the reported mt genome sequences of Babesia canis (B. canis, KC207822), Babesia orientalis (KF218819), Babesia bovis (AB499088), and Theileria equi (AB499091). The evolutionary relationships were analyzed with the amino acid sequences of cytochrome c oxidase I (cox1) and cytochrome b (cob) genes in apicomplexan parasite species. Additionally, the mt genomes of Babesia, Theileria, and Plasmodium spp. were compared in size, host infection, form, distribution, and direction of the protein-coding genes. The full size of the mt genome of B. gibsoni (WH58) was 5865 bp with a linear form, containing terminal-inverted repeats on both ends, six large subunit ribosomal RNA fragments, and three protein-coding genes: cox1, cob, and cytochrome c oxidase III (cox3). Babesia, Theileria, and Plasmodium spp. had a similar mt genome size of about 6000 bp. The mt genomes of parasites that cause canine babesiosis showed a slightly smaller size than the other species. Moreover, Babesia microti (R1 strain) was about 11,100 bp in size, which was twice larger than that of the other species. The mt form was linear for Babesia and Theileria spp. but circular for Plasmodium falciparum and Plasmodium knowlesi. Additionally, all the species contained the three protein-coding genes of cox1, cox3, and cob except Toxoplasma gondii (RH strain) which only contained the cox1 and cob genes. The phylogenetic analysis indicated that B. gibsoni (WH58) was more identical to B. gibsoni (AB499087), B. canis (KC207822), and Babesia rossi (KC207823) and most divergent from Babesia conradae in Babesia spp. Despite the highest similarity to B. gibsoni (AB499087) reported in Japan, B. gibsoni (WH58) showed notable differences in the sequence of nucleotides and amino acids and the property in virulence to host and in vitro cultivation. This study compared the mt genomes of the two B. gibsoni isolates and other parasites in the phylum Apicomplexa and provided new insights into their differences and evolutionary relationships.

RESUMO

One cut homeobox 2 (ONECUT2 or OC-2) is a newly discovered transcription factor. Aberrant expression of OC-2 is closely related to cell proliferation, migration, invasion, and angiogenesis. In this study, we found that OC-2 expression was upregulated in ovarian adenocarcinoma cells, by Western blot analysis. The results of immunohistochemistry showed that the expression of OC-2 was also increased in malignant ovarian cancer tissue. In order to explore the role of OC-2 in the development of ovarian cancer, siRNAs that specifically targets OC-2 were designed. The siRNA targeting OC-2 could effectively inhibit the vascular endothelial growth factor A (VEGFA) expression, but silence and overexpression of VEGFA did not affect OC-2 expression. In addition, OC2-siRNA could block the proliferation, migration, and invasion, and inhibit epithelial-mesenchymal transition and the AKT/ERK signaling pathway, of human ovarian cancer cells in vitro. In a mouse model of ovarian cancer xenograft tumors, OC2-siRNA could significantly inhibit tumor cell growth and the tumor inhibition rate reached approximately 73%. The results of immunohistochemistry showed that the densities of microvessels stained with CD31, the expression of OC-2 and VEGFA were significantly decreased in tumors. These data indicated that OC-2 was an upstream regulator of VEGFA and silencing OC-2 could inhibit ovarian cancer angiogenesis and tumor growth.

RESUMO

OBJECTIVES: To assess the determinants of Patient's Global Assessment of Disease Activity (PtGA) and Physician's Global Assessment of Disease Activity (PhGA) in overall and Japanese patients with rheumatoid arthritis (RA) from two large randomized controlled trials. METHODS: Post hoc analysis of overall and Japanese RA patients who had previous inadequate responses to methotrexate or who had no/minimal previous disease-modifying antirheumatic drug treatment. We examined correlations between PtGA/PhGA and tender joint count in 28 joints (TJC28), swollen joint count in 28 joints (SJC28), inflammatory markers, pain visual analog scale (VAS), and other patient-reported outcomes at baseline, Week 12, and Week 24. Determinants of PtGA/PhGA were identified. RESULTS: In overall populations, pain VAS was the main determinant of PtGA, whereas TJC28 was the main determinant of PhGA in both studies. In Japanese populations, consistent with overall populations, pain VAS was the main determinant of PtGA in both studies; in contrast to overall populations, pain VAS and SJC28/TJC28 played an important role in PhGA. CONCLUSION: Pain was the most important determinant of PtGA, whereas determinants of PhGA varied between populations/studies and were mostly explained by pain/joint counts. Physicians should be aware of patients' perceptions of disease activity when performing assessments/prescribing treatments.

RESUMO

Objective: To investigate the activities of different soft and hard materials during right chewing masticatory muscles, describing the masticatory muscles of time domain and frequency domain features. Methods: 11 experimental subjects who conform to the standards of measurement chew two materials of different soft and hard texture. Then record surface EMG of each bilateral temporalis anterior bundle, masseter, two bilateral anterior abdominal muscles, analysis to 5 kinds of characteristics of the study of EMG. Results: When subjects chewing different soft and hard materials, al the EMG features in the bilateral anterior temporalis and masseter values had significant difference (P < 0.05). The results in bilateral digastric anterior abdominal except zero crossing rate have significant difference; median frequency on the right side of the masticatory muscle has decreased trend. Conclusion: The anterior temporalis and masseter EMG active more intense when chewing hard objects; the right side of the masticatory muscles have obvious fatigue trend after chewing hard masticatory 30 cycles.

RESUMO

Currently, various kinds of electrical stimulation equipment are used in the rehabilitation of muscle function for patients with hemiplegia, but many defects can be found in those designs, for example, insufficient feedback parameter, unsynchronized information, unintuitive display and so on. Therefore, this study introduces an electrical stimulation system with surface electromyography (sEMG) feedback based on LabVIEW, which combines with multi-channel sEMG acquisition, electrical stimulator and other hardware system. This system can not only provide a wide electrical stimulation parameters range for frequency, pulse width and intensity, but also acquire sEMG during the treatment. Meanwhile, this system can compute iEMG, CCR, RMS and MPF in real-time. The verification results shows that the whole system is effective and stable. This system can help physicians observe the muscle condition of different patients, who can explore suitable electrical stimulation parameters to design individualized treatment projects.

RESUMO

The comorbidity profile and overall disease impact are not well understood in psoriasis with and without comorbid psoriatic arthritis (PsA). The objective of this study was to compare disease characteristics, comorbidities, and psoriasis-related quality of life (QOL) in patients with moderate to severe psoriasis with and without comorbid PsA using results from National Psoriasis Foundation (NPF) surveys. The study included 3395 and 2072 patients with psoriasis alone and psoriasis with PsA, respectively. The results showed the burden of psoriasis either independently or with comorbid PsA. As severity of psoriasis increased, patient health and QOL were found to decline.
