0001). In 65% of clusters, men were older than women, while in 35% of clusters women were older than men. Conclusions A large number of circulating phylogenetically distinct HIV-1C lineages (molecular HIV clusters) suggests highly diversified HIV transmission networks across Botswana communities by 2018. The majority (68%) of identified viral lineages were spread across multiple communities.In response to provocative comments by two European clinicians and scientists, the WHO Director General has declared that Africa will not host COVID-19 vaccine trials. Such a stance risks stigmatising COVID-19 vaccine trials in Africa and depriving Africa of critical research. To the contrary, there is a critical need for Africa to host COVID-19 vaccine trials on public health, scientific, and ethics grounds.The induced pluripotent stem cells (iPSCs) offer an unprecedented opportunity to model and study Alzheimer's disease (AD) under patient-specific genetic background. The lower expression of transient receptor potential canonical 6 (TRPC6) was associated with AD patients, which might be involved in AD pathogenesis. However, the role of TRPC6 that played in AD process still needs more investigation in patient-relevant neurons. In this study, the iPSCs were generated from peripheral blood cells of sporadic AD patients and efficiently differentiated into mature cortical neurons. These sporadic AD-bearing neurons displayed higher levels of AD pathological markers Aβ and phospho-tau, but lower levels of TRPC6, than those of control neurons. Treatment of AD neurons with TRPC6 protein fragment or agonist inhibited the elevation of Aβ and phospho-tau. Our results in live AD neurons manifest that the compromised expression of TRPC6 substantially contributed to Aβ pathology of sporadic AD, suggesting that targeting TRPC6 could help to develop novel therapeutic strategies for the treatments of AD.As an alternative electron sink, chlororespiration, comprised of the NAD(P)H dehydrogenase complex and plastid terminal plastoquinone oxidase, may play a significant role for sustaining the redox equilibrium between stroma and thylakoid membrane. This study identified a distinct role of chlororespiration in the marine angiosperm Zostera marina, whose oxygen evolving complex (OEC) is prone to photo-inactivation as a result of its inherent susceptibility to excess irradiation. The strong connectivity between OEC peripheral proteins and key chlororespiratory enzymes, as demonstrated in the interaction network of differentially expressed genes, suggested that the recovery of photo-inactivated OEC was connected with chlororespiration. Chlorophyll fluorescence, transcriptome, and Western blot data verified a new physiological role of chlororespiration to function as photoprotection and generate proton gradient across the thylakoid membrane for the recovery of photo-inactivated OEC. Chlororespiration was only activated in darkness following excess irradiation exposure, which might be related to the electron deficiency in the electron transport chain because of the continuous impairment of OEC. The activation of chlororespiration in Z. marina was prone to proactivity, which was also supported by the further activation of the oxidative pentose-phosphate pathway synthesizing NADPH to meet the demand of chlororespiration during darkness. This phenomenon is distinct from the common assumption that chlororespiration is prone to consuming redundant reducing power during the short transition phase from light to dark.Next-generation sequencing of pathogen quasispecies within a host yields datasets of tens to hundreds of unique sequences. However, the full dataset often contains thousands of sequences, since many of those unique sequences have multiple identical copies. Datasets of this size represent a computational challenge for currently available Bayesian phylogenetic and phylodynamic methods. Through simulations we explore how large datasets with duplicate sequences affect the speed and accuracy of phylogenetic and phylodynamic analysis within BEAST 2. We show that using unique sequences only leads to biases, and using a random subset of sequences yields imprecise parameter estimates. To overcome these shortcomings, we introduce PIQMEE, a BEAST 2 add-on that produces reliable parameter estimates from full datasets with increased computational efficiency as compared to the currently available methods within BEAST 2. The principle behind PIQMEE is to resolve the tree structure of the unique sequences only, while simultaneously estimating the branching times of the duplicate sequences. Distinguishing between unique and duplicate sequences allows our method to perform well even for very large datasets. While the classic method converges poorly for datasets of 6000 sequences when allowed to run for 7 days, our method converges in slightly more than one day. In fact, PIQMEE can handle datasets of around 21000 sequences with 20 unique sequences in 14 days. Finally, we apply the method to a real, within-host HIV sequencing dataset with several thousand sequences per patient.Background Effects of resveratrol on metabolic health have been studied in several short-term human clinical trials, with conflicting results. Next to dose, the duration of the clinical trials may explain the lack of effect in some studies, but long-term studies are still limited. Objectives The objective of this study was to investigate the effects of 6-mo resveratrol supplementation on metabolic health outcome parameters. Methods Forty-one overweight men and women (BMI 27-35 kg/m2; aged 40-70 y) completed the study. In this parallel-group, double-blind clinical trial, participants were randomized to receive either 150 mg/d of resveratrol (n = 20) or placebo (n = 21) for 6 mo. The primary outcome of the study was insulin sensitivity, using the Matsuda index. Secondary outcome measures were intrahepatic lipid (IHL) content, body composition, resting energy metabolism, blood pressure, plasma markers, physical performance, quality of life, and quality of sleep. Postintervention differences between the resveratr resveratrol arm. This trial was registered at Clinicaltrials.gov as NCT02565979.Background Hump recurrence is one of the commonly encountered problems following dorsal preservation rhinoplasty (DP) during the learning period. Objective The aim of this paper is to discuss different methods for the prevention and treatment of dorsal problems following dorsal preservation surgery. Methods One hundred fifty primary rhinoplasty patients were included in our study. The noses were classified as to both hump shape (V- or S-shaped) and height. All patients had a dorsal preservation rhinoplasty with either a push-down (PD) or a let-down (LD) technique. The PD method was used for humps 4mm. Follow up evaluations were made with physical examination and photographs at 1 week, 3 months, and 12 months. Results Mean follow-up was 12.68 ± 1.78 months. 78 humps were V-shaped and 72 were S-shaped. PD was used for 77 cases, LD for 83 cases. 8 patients (5.3%, 8/150) had a visible dorsal hump problem after DP surgery. Based on their preoperative hump shape, 3 cases were V-shaped and 5 were S-shaped. All recurrent cases had a preoperative hump deformity greater than 4 mm. The revision procedures were as follows 4 patients had PD procedure, 3 had a LD procedure, and one patient was treated by classic open resection rhinoplasty. Conclusion We can say that there is a relatively correlation between preoperative hump height and eventual hump recurrence. The complication rate can be decreased with additional technical maneuvers and proper patient selection.Mechanistically connecting genotypes to phenotypes is a longstanding and central mission of biology. selleck kinase inhibitor Deciphering these connections will unite questions and datasets across all scales from molecules to ecosystems. Although high-throughput sequencing has provided a rich platform on which to launch this effort, tools for deciphering mechanisms further along the genome to phenome pipeline remain limited. Machine learning approaches and other emerging computational tools hold the promise of augmenting human efforts to overcome these obstacles. This vision paper is the result of a Reintegrating Biology Workshop, bringing together the perspectives of integrative and comparative biologists to survey challenges and opportunities in cracking the genotype to phenotype code and thereby generating predictive frameworks across biological scales. Key recommendations include promoting the development of minimum "best practices" for the experimental design and collection of data; fostering sustained and long-term data repositories; promoting programs that recruit, train, and retain a diversity of talent and providing funding to effectively support these highly cross-disciplinary efforts. We follow this discussion by highlighting a few specific transformative research opportunities that will be advanced by these efforts.Background The association of dietary pattern with the risk of basal cell carcinoma (BCC) is little understood and has scarcely been investigated. Objectives We assessed the association of several complete dietary patterns [Mediterranean, Dietary Approaches to Stop Hypertension (DASH), and Pro-vegetarian dietary pattern] with the risk of BCC, conducting a nested case-control study (4 controls for each case). Methods Cases and controls were selected from the SUN (Seguimiento Universidad de Navarra) cohort using risk set sampling. Cases were identified among subjects free of skin cancer at baseline but who later reported a physician-made BCC diagnosis during the follow-up period. In the cohort we identified 101 incident cases of BCC. Results In multivariable-adjusted conditional logistic regression analyses, better adherence to the Mediterranean diet (highest compared with lowest quintile) was associated with a 72% relative reduction in the odds of BCC (OR 0.28; 95% CI 0.10, 0.77; Ptrend = 0.014); the DASH diet was associated with a 68% RR reduction (OR 0.32; 95% CI 0.14, 0.76; Ptrend = 0.013) for the comparison between extreme quintiles. No association was found between a Pro-vegetarian dietary pattern and BCC. Higher fruit consumption (highest compared with lowest quintile, OR 0.27; 95% CI 0.11, 0.64; Ptrend less then 0.001) and low-fat dairy products (OR 0.39; 95% CI 0.16, 0.92; Ptrend = 0.014) were associated with a lower BCC risk. Conclusions Our results suggest that Mediterranean and DASH dietary patterns may be associated with a lower risk of BCC, but confirmatory studies are required.Summary Unipept is an ecosystem of tools developed for fast metaproteomics data-analysis consisting of a web application, a set of web services (API) and a command-line tool (CLI). After the successful introduction of version 4 of the Unipept web application, we here introduce version 2.0 of the API and CLI. Next to the existing taxonomic analysis, version 2.0 of the API and CLI provides access to Unipept's powerful functional analysis for metaproteomics samples. The functional analysis pipeline supports retrieval of EC numbers, GO terms and InterPro entries for the individual peptides in a metaproteomics sample. This paves the way for other applications and developers to integrate these new information sources into their data processing pipelines, which greatly increases insight into the functions performed by the organisms in a specific environment. Both the API and CLI have also been expanded with the ability to render interactive visualisations from a list of taxon ids. These visualisations are automatically made available on a dedicated website and can easily be shared by users.
