Partial nephrectomy has become the gold standard treatment for small renal masses. This study aimed to assess the impact of soft coagulation hemostasis on parenchymal volume reduction of the operated kidney after an open partial nephrectomy. We retrospectively reviewed 94 patients with small renal tumors who underwent open partial nephrectomy with soft-coagulation hemostasis at our institution.

The tetrapod double cone is a pair of tightly associated cones called the "principal" and the "accessory" member. It is found in amphibians, reptiles, and birds, as well as monotreme and marsupial mammals but is absent in fish and eutherian mammals. To explore the potential evolutionary origins of the double cone, we analyzed single-cell and -nucleus transcriptomic atlases of photoreceptors from six vertebrate species: zebrafish, chicken, lizard, opossum, ground squirrel, and human.

Article Synopsis
  • Catamenial pneumothorax (CP) is a rare condition affecting women, characterized by a collapsed lung associated with menstrual cycles, while Meigs syndrome (MS) involves benign ovarian tumors causing pleural effusion and ascites, and its exact causes are not well understood.
  • A 40-year-old Japanese woman was diagnosed with CP after experiencing dyspnea and undergoing surgery that revealed diaphragmatic foramens.
  • Ten years later, the same patient presented with chest pain and imaging showed signs of MS, leading to surgery that resolved her symptoms, highlighting the rare occurrence of both conditions in one patient and suggesting links between them.

  • Asymptomatic bronchial artery aneurysms (BAA) are rare but potentially fatal if they rupture, and the best treatment is bronchial artery embolization (BAE), which is minimally invasive.
  • A 74-year-old man was diagnosed with a mediastinal BAA after a CT scan showed a suspicious lesion, but during BAE, complications led to acute aortic dissection, requiring urgent surgical repair.
  • The situation highlighted the need for a flexible treatment approach, suggesting that TEVAR could be a viable option for BAA in challenging cases, ensuring prompt responses to complications like aortic dissection.

Unlike humans, teleosts like zebrafish exhibit robust retinal regeneration after injury from endogenous stem cells. However, it is unclear if regenerating cone photoreceptors regain physiological function and integrate correctly into post-synaptic circuits. We used two-photon calcium imaging of living adult retina to examine photoreceptor responses before and after light-induced lesions.

African-ancestry (AA) participants are underrepresented in genetics research. Here, we conducted a transcriptome-wide association study (TWAS) in AA female participants to identify putative breast cancer susceptibility genes. We built genetic models to predict levels of gene expression, exon junction, and 3' UTR alternative polyadenylation using genomic and transcriptomic data generated in normal breast tissues from 150 AA participants and then used these models to perform association analyses using genomic data from 18,034 cases and 22,104 controls.

Vertebrates rely on rod photoreceptors for vision in low-light conditions. The specialized downstream circuit for rod signalling, called the primary rod pathway, is well characterized in mammals, but circuitry for rod signalling in non-mammals is largely unknown. Here we demonstrate that the mammalian primary rod pathway is conserved in zebrafish, which diverged from extant mammals ~400 million years ago.

Article Synopsis
  • Black women have the highest breast cancer mortality rates, prompting a study on the VEGF-hypoxia gene expression signature across diverse populations, specifically focusing on breast tumors from Nigeria and Chicago.
  • A new gene expression panel was used to find that the VEGF-hypoxia signature is most prevalent in the basal-like subtype of breast cancer, particularly in Black women, and is associated with necrotic tumors showing links to proliferation.
  • The study highlights the need for targeted interventions addressing the VEGF-hypoxia signature and the immune microenvironment to improve survival rates in aggressive breast cancers affecting Black women.

Vertebrates rely on rod photoreceptors for vision in low-light conditions. Mammals have a specialized downstream circuit for rod signaling called the primary rod pathway, which comprises specific cell types and wiring patterns that are thought to be unique to this lineage. Thus, it has been long assumed that the primary rod pathway evolved in mammals.

Radical cystectomy is a gold-standard treatment for muscle-invasive bladder cancer. We recently introduced robot-assisted radical cystectomy (RARC) with perioperative enhanced recovery after surgery (ERAS). The medical records of patients with bladder cancer who underwent open radical cystectomy (ORC) or RARC/ERAS at NTT Medical Center Tokyo were retrospectively reviewed to compare the surgical outcomes, hospital stay, and medical costs between groups.

Background: Endocrine-resistant HR+/HER2- breast cancer (BC) and triple-negative BC (TNBC) are of interest for molecularly informed treatment due to their aggressive natures and limited treatment profiles. Patients of African Ancestry (AA) experience higher rates of TNBC and mortality than European Ancestry (EA) patients, despite lower overall BC incidence. Here, we compare the molecular landscapes of AA and EA patients with HR+/HER2- BC and TNBC in a real-world cohort to promote equity in precision oncology by illuminating the heterogeneity of potentially druggable genomic and transcriptomic pathways.

The vertebrate inner retina is driven by photoreceptors whose outputs are already pre-processed; in zebrafish, outer retinal circuits split "color" from "grayscale" information across four cone-photoreceptor types. It remains unclear how the inner retina processes incoming spectral information while also combining cone signals to shape grayscale functions. We address this question by imaging the light-driven responses of amacrine cells (ACs) and bipolar cells (BCs) in larval zebrafish in the presence and pharmacological absence of inner retinal inhibition.

Zebrafish retinal cone signals shift in spectral shape through larval, juvenile, and adult development as expression patterns of eight cone-opsin genes change. An algorithm extracting signal amplitudes for the component cone spectral types is developed and tested on two thyroxin receptor β2 (trβ2) gain-of-function lines and , allowing correlation between opsin signaling and opsin immunoreactivity in lines with different developmental timing and cell-type expression of this red-opsin-promoting transgene. Both adult transgenics became complete, or nearly complete, "red-cone dichromats," with disproportionately large long-wavelength-sensitive (LWS)1 opsin amplitudes as compared with controls, where LWS1 and LWS2 amplitudes were about equal, and significant signals from SWS1, SWS2, and Rh2 opsins were detected.

Cancer stem cells (CSCs) are major contributors to the malignant transformation of cells because of their capacity for self-renewal. Aldehyde dehydrogenase1A1 (ALDH1A1) and CD133 are promising candidate of CSC markers in non-small cell lung cancer (NSCLC). Furthermore, TP53 is frequently mutated in lung cancer, and the loss of its function is associated with malignant characteristics.
