Efficient ternary organic solar cells with suppressed nonradiative recombination via B‒N based polymer donor.

Organic solar cells (OSCs) have developed rapidly in recent years. However, the energy loss ( ) remains a major obstacle to further improving the photovoltaic performance. To address this issue, a ternary strategy has been employed to precisely tune the and boost the efficiency of OSCs.

Placode and neural crest origins of congenital deafness in mouse models of Waardenburg-Shah syndrome.

Mutations in the human genes encoding the endothelin ligand-receptor pair and cause Waardenburg-Shah syndrome (WS4), which includes congenital hearing impairment. The current explanation for auditory dysfunction is defective migration of neural crest-derived melanocytes to the inner ear. We explored the role of endothelin signaling in auditory development in mice using neural crest-specific and placode-specific mutation plus related genetic resources.

Cumulative Dispensing of Oral Corticosteroids Over 12 Months in People with COPD.

Purpose: Oral corticosteroids (OCS) are recommended for the treatment of exacerbations in people with COPD; however, high cumulative lifetime doses (≥1000mg prednisolone-equivalent) are associated with adverse health effects. This issue is well defined in asthma but is less well understood in COPD. The aim of this study was to examine cumulative OCS dispensed to people with COPD over 12 months.

A union of two rare pathologies: small bowel diverticula perforation secondary to impacted gallstone ileus.

An 84-year-old lady presented with 1 day history of sudden onset generalized abdominal pain, fevers, and peritonism. Computed tomography was suggestive of a mid-small bowel perforation associated with a distal ovoid soft tissue density structure without pneumobilia. An urgent laparotomy demonstrated two areas of jejunal diverticula necrosis and perforation associated with a 3 cm luminal mass in the proximal ileum, and proximal small bowel dilatation.

Lymphomatoid Papulosis Type E With T-Cell Receptor Gamma Positivity.

Lymphomatoid papulosis (LyP) is currently categorized as a primary lymphoproliferative disorder that follows a chronic, recurrent clinical course. The diagnosis of LyP is mainly based on clinical presentation and histopathological correlation. Six subtypes of LyP have been described and recognized, each with different histological features and sometimes distinct clinical presentations.

Ligand-induced changes in the electrocatalytic activity of atomically precise Au nanoclusters.

Atomically precise gold nanoclusters have shown great promise as model electrocatalysts in pivotal electrocatalytic processes such as the hydrogen evolution reaction (HER) and carbon dioxide reduction reaction (CORR). Although the influence of ligands on the electronic properties of these nanoclusters is well acknowledged, the ligand effects on their electrocatalytic performances have been rarely explored. Herein, using [Au(SR)] nanoclusters as a prototype model, we demonstrated the importance of ligand hydrophilicity hydrophobicity in modulating the interface dynamics and electrocatalytic performance.

How do we measure the costs, benefits, and harms of sharing data from biomedical studies? A protocol for a scoping review.

Introduction: The benefits of sharing participant-level data, including clinical or epidemiological data, genomic data, high-dimensional imaging data, or human-derived samples, from biomedical studies have been widely touted and may be taken for granted. As investments in data sharing and reuse efforts continue to grow, understanding the cost and positive and negative effects of data sharing for research participants, the general public, individual researchers, research and development, clinical practice, and public health is of growing importance. In this scoping review, we will identify and summarize existing evidence on the positive and negative impacts and costs of data sharing and how they are measured.

Ocular Telangiectasia and Cerebellar Atrophy in Ataxia-Telangiectasia (Louis-Bar Syndrome).

Background: Ataxia-telangiectasia (Louis-Bar syndrome) is a rare genetic disorder characterized by progressive ataxia, ocular telangiectasias, immunodeficiency and increased cancer risk due to impaired DNA repair.

Phenomenology Shown: Thorough clinical and subsequently radiological examination in a 19-year-old woman with a history of previously undiagnosed, progressive gait ataxia since early childhood, diffuse large B-cell lymphoma and severe combined immunodeficiency revealed the eponymous features of the disease, ocular telangiectasias and cerebellar atrophy, enabling targeted genetic testing.

Educational Value: Ocular telangiectasias represent an important clue for a diagnosis of ataxia-telangiectasia in young patients with progressive ataxia, implicating awareness of increased malignancy risk and treatment of immunodeficiency.

GBR assisted Onlay bone grafting for the posterior maxillary horizontal ridge augmentation: a case report and literature review.

The posterior mandible is the primary area for occlusal function. However, long-term tooth loss in the posterior mandible often leads to rapid absorption of both buccal and lingual trabecular bone plates and subsequent atrophy of the alveolar ridge. This ultimately results in horizontal bone deficiencies that complicate achieving an optimal three-dimensional placement for dental implants.
