Nasopharyngeal carcinoma (NPC) is an Asia-prevalent malignancy, yet its genetic underpinnings remain incompletely understood. Here, a transcriptome-wide association study (TWAS) is conducted on NPC, leveraging gene expression prediction models based on epithelial tissues and genome-wide association study (GWAS) summary statistics from 1577 NPC cases and 6359 controls of southern Chinese descent. The TWAS identifies VAMP8 on chromosome 2p11.

Objectives: The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) categorizes fine needle aspiration and cytology (FNAC) results into 6 tiers and assigns a risk of malignancy (ROM) to each category. Its utility in submandibular gland lesions remains unclear. Our article aims to study (1) the utility of the MSRSGC in classifying FNAC of submandibular gland masses, (2) describe the demographics and incidence of submandibular gland malignancy in our population, and (3) analyze the accuracy of FNAC in diagnosis of benign and malignant submandibular gland tumors.

The additive hazard model, which focuses on risk differences rather than risk ratios, has been widely applied in practice. In this paper, we consider an additive hazard model with varying coefficients to analyze recurrent events data. The model allows for both varying and constant coefficients.

Data regarding Penicillin allergy labels (PALs) from India and Sri Lanka are sparse. Emerging data suggests that the proportion of patients declaring an unverified PAL in secondary care in India and Sri Lanka (1%-4%) is lesser than that reported in High Income Countries (15%-20%). However, even this relatively small percentage translates into a large absolute number, as this part of the world accounts for approximately 25% of the global population.

Large-scale reforestation is promoted as an important strategy to mitigate climate change and biodiversity loss. A persistent challenge for efforts to restore ecosystems at scale is how to accelerate ecological processes, particularly natural regeneration. Yet, despite being recognized as an important barrier to the recovery of diverse plant communities in tropical agricultural landscapes, the impacts of dispersal limitation on natural regeneration in secondary forests-and especially how this changes as these forests grow older-are still poorly studied.

Aim: Cryptoglandular anal fistulas carry a substantial burden to quality of life. Surgery is the only effective curative treatment but requires balancing fistula healing against pain, wounds and continence impairment. Sphincter-preserving procedures do exist but demonstrate variable rates of success.

We studied the SES-honour link in 5 studies (N = 13,635) with participants recruited in different world regions (the Mediterranean and MENA, East Asian, South-East Asian, and Anglo-Western regions) using measures that tap into various different facets of honour. Findings from these studies revealed that individuals who subjectively perceived themselves as belonging to a higher (vs.

Climate change and global warming are terms used to describe the variation in the Earth's mean temperature as a result of human activities contributing to the formation of urban heat islands (UHI). One method for determining the temperature of a region is the land surface temperature (LST). The study of LSTs is important and closely related to climate change, as is the provision of convenient living and working conditions in cities, which support economic growth.

This study introduces EpiAgePublic, a new method to estimate biological age using only three specific sites on the gene known for its connection to aging. Unlike traditional methods that require complex and extensive data, our model uses a simpler approach that is well-suited for next-generation sequencing technology, which is a more advanced method of analyzing DNA methylation. This new model overcomes some of the common challenges found in older methods, such as errors due to sample quality and processing variations.

Background: Epidemiologic studies have shown that daily exposure to incense smoke is associated with greater risk of cardiovascular mortality, which suggests that chronic exposure to incense could be linked to atherosclerosis. We studied the association between home incense use and the risk of chronic limb-threatening ischemia (CLTI), the most severe outcome of peripheral arterial disease.
Methods: We used data from the Singapore Chinese Health Study, which recruited 63,257 Chinese participants 45-74 years old from 1993-1998.

Pertussis, or whooping cough, is a highly contagious respiratory infection caused by the Gram-negative bacterium . Although traditionally associated with children, pertussis is increasingly prevalent among adults, particularly those with comorbidities or weakened immune systems, where it can lead to severe complications. Diagnosing pertussis in adults can be challenging due to its nonspecific symptoms, underreporting, and the limited sensitivity of available diagnostic tests.

Adjuvants are a diverse group of substances that can be added to vaccines to enhance antigen-specific immune responses and improve vaccine efficacy. The first adjuvants, discovered almost a century ago, were soluble crystals of aluminium salts. Over the following decades, oil emulsions, vesicles, oligodeoxynucleotides, viral capsids, and other complex organic structures have been shown to have adjuvant potential.

Although the Coronavirus disease 2019 (COVID-19) pandemic has ended, there are still many important lessons we can learn, as the pandemic profoundly affected every area of laboratory practice. During the pandemic, extensive changes to laboratory staffing had to be implemented, as many healthcare institutions required regular screening of all healthcare staff. Several studies examined the effectiveness of different screening regimens and concluded that repeated testing, even with lower sensitivity tests, could rival the performance of gold-standard RT-PCR testing in the detection of new cases.

This study optimizes the CuO/GaO heterojunction diodes (HJDs) by tailoring the structural parameters of CuO layers. The hole concentration in the sputtered CuO was precisely controlled by adjusting the Ar/O gas ratio. Experimental investigations and TCAD simulations were employed to systematically evaluate the impact of the CuO layer dimension and hole concentration on the electrical performance of HJDs.

The large-scale implementation of 2D material-based membranes is hindered by mechanical stability and mass transport control challenges. This work describes the fabrication, characterisation, and testing of self-standing graphene oxide (GO) membranes cross-linked with oxides such as FeO, AlO, CaSO, NbO, and a carbide, SiC. These cross-linking agents enhance the mechanical stability of the membranes and modulate their mass transport properties.

Inspired by our recent success in designing CO-phobic and CO-philic domains on nano-MgO for effective CO adsorption, our ongoing efforts focus on incorporating dopants into pristine MgO to further enhance its CO adsorption capabilities. However, a clear set of guidelines for dopant selection and a holistic understanding of the underlying mechanisms is still lacking. In our investigation, we combined first-principles calculations with experimental approaches to explore the crystal and electronic structural changes in MgO doped with high-valence elements (Al, C, Si, and Ti) and their interactions with CO.

In this paper, we construct -ary codes for correcting a burst of at most deletions, where t,q≥2 are arbitrarily fixed positive integers. We consider two scenarios of error correction: the classical error correcting codes, which recover each codeword from one read (channel output), and the reconstruction codes, which allow to recover each codeword from multiple channel reads. For the first scenario, our construction has redundancy logn+8loglogn+o(loglogn) bits, encoding complexity O(q7tn(logn)3) and decoding complexity O(nlogn).
