Introduction: Trilaciclib is a transient cyclin-dependent kinase 4/6 inhibitor that decreases the incidence of chemotherapy-induced myelosuppression in extensive-stage small cell lung cancer (ES-SCLC). TRACES study was designed to assess the safety, efficacy and pharmacokinetics (PK) of trilaciclib before chemotherapy in Chinese patients with ES-SCLC.

Methods: The study included an open-label safety run-in part (Part 1) and double-blinded, placebo-controlled part (Part 2) where patients received trilaciclib or placebo before chemotherapy.

Article Synopsis
  • Teleost fishes are the most diverse group of vertebrates and have a history of polyploidy, including instances of subgenome dominance where one subgenome is more expressed than the other.
  • Recent research analyzed the genomes of 21 cyprinids (like common carp and goldfish) to explore subgenome evolution after multiple allopolyploidy events.
  • The study found that subgenome dominance likely results from factors like maternal influence and the density of transposable elements, shedding light on how polyploidy affects evolution in these fishes.

The origin and colonization history of , a genus of small arboreal tree frogs breeding exclusively in shallow swamps, is under disputed. On the basis of comprehensive sampling program, the evolutionary history of is investigated based on 3 mitochondrial genes. Our results indicate that the genus originated in the Asian mainland and subsequently arrived at its current distribution in Borneo, Taiwan, Ryukyu, and Hainan islands by a series of dispersal events.

  • * Surface plasmon resonance (SPR) analysis was used to assess how well these compounds bind to α-glucosidase, while mathematical models helped evaluate the concentration and binding kinetics of the drugs in the vicinity of the enzyme.
  • * The researchers developed a predictive model for drug-α-glucosidase interactions that demonstrated the effective synergistic effects of these tea polyphenols, supporting the therapeutic rationale for using traditional Chinese medicine

Aim: With the late Cenozoic uplift of the Qinghai-Tibetan Plateau (QTP), drainage of the southeastern edge of the QTP changed significantly. However, the impact of this dramatic change on the geographical distribution and genetic diversity of endemic organisms is still poorly understood. Here, we examined the geographical patterns of genetic variation in the Yunnan small narrow-mouthed frog, (Microhylidae), and two alternative hypotheses were tested: That is, the geographical distribution of genetic variation was determined by either the contemporary drainage basin or historical drainage basins.

The ferret-badger was first described from Cuc Phuong National Park in Vietnam, with no subsequent reports in later years. During our surveys of the Wuyishan Mountains of Fujian Province in southeastern China during May 2018, a specimen was identified. Analysis based on pelage and skull characteristics as well as molecular data indicated it to be a new subspecies, which we nominated as .

The systematics of Semisulcospiridae in China is revised here based on morphological characters and mitochondrial phylogenetics. Phylogenetic relationships within the Chinese semisulcospirids were assessed via DNA sequences from mitochondrial analysis (cytochrome c oxidase I and 16S rRNA). This research contains most morphospecies of semisulcospirids previously recorded in China.

Improvement of crop drought resistance and water-use efficiency (WUE) has been a major endeavor in agriculture. Arabidopsis ENHANCED DROUGHT TOLERANCE1/HOMEODOMAIN GLABROUS11 (AtEDT1/HDG11), a homeodomain-START transcription factor we previously identified from the enhanced drought tolerance1 mutant (edt1), has been demonstrated to improve drought tolerance and WUE significantly in multiple plant species when constitutively overexpressed. Here, we report the genetic evidence suggesting a genetic pathway, which consists of EDT1/HDG11, ERECTA, and E2Fa loci, and regulates WUE by modulating stomatal density.

Prion diseases are characterized by the conformational conversion of the cellular prion protein (PrP) to the pathogenic isoform (PrP). Lipids have been found to interact with PrP and contribute to the efficient formation of PrP. Non-mammalian PrPs are not readily to undergo the conversion process into an infectious isoform, yet the effect of lipid on the conformational conversion of non-mammalian PrP remains to be explored.

In the field of traditional Chinese medicine(TCM),the definition of "Shen" contains a broad concept and a narrow concept. Broad "Shen" is the dominator and administrator of human vital movement,while narrow "Shen" means spirit, consciousness, thinking and emotions of human. "Shen" originates from innate essence of parents, and survives on acquired essence of water and food as well as the nutrition of its metaplastic Qi-Blood-Body fluid.

Aim: Through analysis and summarization of clinicopathological features, immunohistochemical expression, pathological diagnostic criteria, prognostic and other factors in patients suffering from bladder neuroendocrine carcinoma (BNEC), a better understanding of BNEC could be achieved to provide solid evidence for clinicopathology and prognosis.

Materials And Methods: The clinicopathological data of 39 cases of BNEC with up to 5-year follow-up data (median follow-up=650 days) were analyzed retrospectively based on immunohistochemical staining. Survival analyses were carried out using the Kaplan-Meier method and tested with the log-rank method.

Paraplegic gait orthosis has been shown to help paraplegic patients stand and walk, although this method cannot be individualized for patients with different spinal cord injuries and functional recovery of the lower extremities. There is, however, a great need to develop individualized paraplegic orthosis to improve overall quality of life for paraplegic patients. In the present study, 36 spinal cord (below T4) injury patients were equally and randomly divided into control and observation groups.

There have been a few epidemiological studies reporting VDR polymorphisms including Fok1, Bsm1, Apa1 and Taq1 with skin cancer incidence and, therefore, risk. The results, however, are controversial, often due to smaller sample size. Concerning most of the studies were performed on Caucasian population, we conducted this comprehensive analysis to better understand roles of the polymorphisms in skin cancer development among Caucasian population.

Epidermal growth factor receptor (EGFR) is considered to be one of the key driver genes in non-small cell lung cancer (NSCLC). Several clinical trials have shown great promise of EGFR tyrosine kinase inhibitors (TKIs) in the first-line treatment of NSCLC. Many advances have been made in the understanding of EGFR signal transduction network and the interaction between EGFR and tumor microenvironment in mediating cancer survival and development.
