The yeast buds at sites pre-determined by cortical landmarks deposited during prior budding. During mating between haploid cells in the lab, external pheromone cues override the cortical landmarks to drive polarization and cell fusion. By contrast, in haploid gametes (called spores) produced by meiosis, a pre-determined polarity site drives initial polarized morphogenesis independent of mating partner location.

The superiority of prostate-specific membrane antigen (PSMA) positron emission tomography (PET) over conventional staging methods such as computed tomography (CT) and bone scintigraphy has now been demonstrated for almost all clinical stages of prostate cancer. In primary diagnostics, PSMA-PET/CT is therefore the new standard for risk-adapted whole-body staging. At the same time, PSMA-PET/CT provides a new risk-based classification for predicting overall survival across all early and late stages of the disease.

Coronaviruses are characterized by their progeny assembly and budding in the endoplasmic reticulum-Golgi intermediate compartment (ERGIC). Our previous studies demonstrated that truncation of 9 amino acids in the cytoplasmic tail (CT) of the infectious bronchitis virus (IBV) spike (S) protein impairs its localization to the ERGIC, resulting in increased expression at the plasma membrane. However, the precise mechanism underlying this phenomenon remained elusive.

Pesticides and plastics have brought convenience to agricultural production and daily life, but they have also led to environmental pollution through residual chemicals. Emamectin benzoate (EMB) is among the most widely used insecticides, which can cause environmental pollution and harm the health of organisms. Additionally, microplastics (MPs), a relatively new type of pollutant, not only are increasing in residual amounts within water bodies and aquatic organisms but also exacerbate pollution by adsorbing other pollutants, leading to a mixed pollution scenario.

Introduction: SPLASH (NCT04647526) is a multicenter phase III trial evaluating the efficacy and safety of [Lu]Lu-PNT2002 radioligand therapy in metastatic castration-resistant prostate cancer (mCRPC). This study leveraged a lead-in phase to assess tissue dosimetry and evaluate preliminary safety and efficacy, prior to expansion into a randomized phase. Here we report those results.
