While flowering plants have diversified in virtually every terrestrial clime, climate constrains the distribution of individual lineages. Overcoming climatic constraints may be associated with diverse evolutionary phenomena including whole genome duplication (WGD), gene-tree conflict, and life-history changes. Climatic shifts may also have facilitated increases in flowering plant diversification rates.

Article Synopsis
  • - Vaccinieae is a diverse group within the Ericaceae family, consisting of about 1430 species, primarily tropical, but well-known for temperate crops like blueberries and cranberries.
  • - A phylogenomic study of 210 species revealed that Vaccinieae likely originated in temperate North America around 30 million years ago, with tropical species resulting from multiple migrations from these northern ancestors.
  • - Findings indicate significant evolutionary events, including a unique ovary structure development and a major polyploid event, suggesting that Vaccinium's classification needs reevaluation due to its complex evolutionary history.

Background: The influence of native secondary succession associated with anthropogenic disturbance on the biodiversity of the forests in subtropical China remains uncertain. In particular, the evolutionary response of small understory shrubs, particularly pioneer species inhabiting continuously disturbed habitats, to topographic heterogeneity and climate change is poorly understood. This study aimed to address this knowledge gap by focusing on the Gaultheria crenulata group, a clade of small pioneer shrubs in subtropical China.

  • The study focuses on how biogeographic dispersal has impacted plant diversity in the Himalaya-Hengduan Mountains, specifically examining the alpine clade Gaultheria ser. Trichophyllae.
  • Through phylogenetic analysis, researchers analyzed dispersal patterns, revealing a trend of eastward dispersals within regions and westward dispersals between regions, influenced by climatic changes over time.
  • The findings suggest that the timing of these dispersals, especially during glacial and interglacial periods, plays a crucial role in shaping the current species richness of G. ser. Trichophyllae.

Background: Childhood cancer survivors are at increased risk of developing cardiovascular diseases, presenting as the main causes of morbidity and mortality within this group. Besides the usual primary and secondary prevention in combination with screening during follow-up, the modifiable lifestyle factors of physical activity, nutrition, and body weight have not yet gained enough attention regarding potential cardiovascular risk reduction.

Objective: These practical recommendations aim to provide summarised information and practical implications to paediatricians and health professionals treating childhood cancer survivors to reduce the risk of cardiovascular late effects.

Article Synopsis
  • The text discusses a group of aromatic shrubs found primarily in subtropical and East Asian tropical areas, noting the need for better taxonomic classification due to their complexity.
  • A study focused on populations from mainland China revealed five distinct populations with notable morphological and habitat variations and involved field surveys and phylogenetic analysis to clarify relationships.
  • The research resulted in the identification of three new species, the elevation of one variety to species status, and the reclassification of certain varieties as synonyms, along with the provision of a comprehensive key and descriptions for the five recognized species.

The angiosperm family Primulaceae is morphologically diverse and distributed nearly worldwide. However, phylogenetic uncertainty has obstructed the identification of major morphological and biogeographic transitions within the clade. We used target capture sequencing with the Angiosperms353 probes, taxon-sampling encompassing nearly all genera of the family, tree-based sequence curation, and multiple phylogenetic approaches to investigate the major clades of Primulaceae and their relationship to other Ericales.

Article Synopsis
  • The true blueberries, a group native to North America, are ecologically and economically important but poorly understood due to confusion over species boundaries and an unclear evolutionary history.
  • This study presents the first phylogenomic analysis of the diploid blueberries, using techniques like flow cytometry and target enrichment to gather genomic data.
  • The findings established monophyly for most morphospecies, identified exceptions, and suggested a hybrid origin for one taxon, paving the way for future research on taxonomic classification and evolutionary relationships in this group.

The zebrafish has been considered an ideal model for studies of complex behaviors since its behavioral repertoire is well described. Therefore, this study evaluated the perceived pain through behavioral changes in zebrafish larvae. Here we investigated the Acetic Acid (AA) effects on zebrafish larvae exposed in a short-time period (60 s) and the preventive effect from routinely used compounds, Dimethyl Sulfoxide (DMSO), Ethanol (EtOH), Ibuprofen (IBP), and Paracetamol (PAR).

The mountains of subtropical China are an excellent system for investigating the processes driving the geographical distribution of biodiversity and radiation of plant populations in response to Pleistocene climate fluctuations. How the major mountain ranges in subtropical China have affected the evolution of plant species in the subtropical evergreen broadleaved forest is an issue with long-term concern. Here, we focused on , a woody species endemic to the southern mountain ranges in subtropical China, to elucidate its population dynamics.

from the Dulong Jiang valley in northwestern Yunnan Province, China and the Babulongtan mountain range in northern Kachin State, Myanmar is here described as a new species of the Dipentodontaceae. It is the third species of the genus to be recognized for China and the first to be reported for Myanmar. It is similar to but differs by characters of its leaf margins, inflorescences, and fruit.

  • - This study greatly expands the understanding of flowering plants' evolutionary relationships by assembling the largest dataset of plastomes, combining data from 4,792 plastomes across 4,660 species and 2,024 genera.
  • - The resulting phylogenetic tree provides strong support for many previously unclear relationships among plant families and orders, particularly within core eudicots, allowing a better understanding of their evolutionary history.
  • - Despite significant findings, some relationships, especially among the major clades of Mesangiospermae, remain unresolved, indicating further research is needed due to the complexity of early plant evolution.

from the ultramafic summit of Mt. Victoria, Palawan Island, Philippines is here described as a new species of Ericaceae. It closely resembles but is distinct by having much shorter petioles and leaves, longer and glabrous calyx lobes with serrate lobe margins, a larger corolla with deeper sulcations, and longer stamens with spurs oriented laterally.

Oxytetracycline (OTC) is one of the broad-spectrum antibiotics widely used for the treatment of fish-farm infection. Considering that behavior is directly related to reproduction, individual fitness, and survival, it is important to evaluate the impact of antibiotics on the behavioral repertoire in fish. Zebrafish (Danio rerio) presents a well-described behavioral repertoire to reliably demonstrate complex responses to chemical compound exposure.

Identifying the contours and correlates of species turnover is central to understanding the nature of biogeographical regions. The Hengduan Mountains region of south-central China (HMR) is well known for its high diversity of plants, but its boundaries and internal floristic structure are poorly understood, especially in relation to geographical and environmental factors. With data on occurrences and elevational ranges of seed plants across the HMR and adjacent areas of the greater Qinghai-Tibet Plateau, we identified motifs (distinct species assemblages) by Grade of Membership models, and characterized relative contributions of geography, elevation, and climate to their spatial patterns.

Background And Objectives: We examined retrospectively whether the combination of standard dacarbazine (DTIC) and/or fotemustine chemotherapy and autologous peptide-loaded dendritic cell (DC) vaccination may improve survival of stage IV melanoma patients. Furthermore, a small cohort of long-term survivors was studied in more detail.

Patients And Methods: Between 1998 and 2008, 41 patients were vaccinated at least three times with DCs while receiving chemotherapy and compared to all other 168 patients in our database who only received chemotherapy (1993-2008).
