U2AF1 mutations rescue deleterious exon skipping induced by KRAS mutations.

The mechanisms by which somatic mutations of splicing factors, such as U2AF1 in lung adenocarcinoma, contribute to cancer pathogenesis are not well understood. Here, we used prime editing to modify the endogenous gene in lung adenocarcinoma cells and assessed the resulting impact on alternative splicing. These analyses identified as a key target modulated by U2AF1.

Variation of Ambient Illumination Across Different Locations: An Impact on Antimyopia Strategy.

Purpose: To evaluate whether the level of ambient illumination in winter at different locations, time of a day, sun protection, and source position remains optimum (≥1000 lux) for controlling myopia progression.

Methods: Illuminance level was recorded for 6 outdoor and 5 indoor locations using factory calibrated digital lux meter and under different measurement conditions. Outdoor locations included "open playground," "between two buildings," "between three buildings," "under a porch facing east," "under a big tree," and "under a porch facing west.

Lutein and Zeaxanthin: Source, Extraction, Stability, Bioactivity, and Functional Food Applications.

Nature has been acknowledged as a fundamental source of diverse bioactive molecules. Among natural carotenoids, lutein, zeaxanthin, and their oxidative metabolites are specifically deposited in the macular region of living organisms. Lutein and zeaxanthin are carotenoids primarily found in green leafy vegetables, eggs, and various fruits.

Foodomics: A sustainable approach for the specific nutrition and diets for human health.

Foodomics is an interdisciplinary field that integrates various omics technologies to explore the complex relationship between food and human health in depth. This approach offers valuable insights into the biochemical, molecular, and cellular composition of food by employing advanced omics techniques. Its applications span the food industry and human health, including efforts to combat malnutrition, provide dietary recommendations, and ensure food safety.

An essential role for Cmtr2 in mammalian embryonic development.

CMTR2 is an mRNA cap methyltransferase with poorly understood physiological functions. It catalyzes 2'-O-ribose methylation of the second transcribed nucleotide of mRNAs, potentially serving to mark RNAs as "self" to evade the cellular innate immune response. Here we analyze the consequences of Cmtr2 deficiency in mice.

XRN1 deletion induces PKR-dependent cell lethality in interferon-activated cancer cells.

Emerging data suggest that induction of viral mimicry responses through activation of double-stranded RNA (dsRNA) sensors in cancer cells is a promising therapeutic strategy. One approach to induce viral mimicry is to target molecular regulators of dsRNA sensing pathways. Here, we show that the exoribonuclease XRN1 is a negative regulator of the dsRNA sensor protein kinase R (PKR) in cancer cells with high interferon-stimulated gene expression.

Non-pathologic components are associated with reduced visual acuity in myopes after spectacle correction.

Purpose: To find the association between reduced best-corrected visual acuity and non-pathologic components after optical correction in individuals with low to high myopia.

Methods: Myopic children under 16 years of age were reviewed using electronic medical records and the following data were extracted and recorded: participant's age, gender, uncorrected visual acuity (UCVA), manifest refraction, and best corrected visual acuity (BCVA). Spherical equivalent and cylinder were classified into low, moderate, and high categories based on the magnitude range.

Epsilon poly-lysine in buffalo semen extender: A step towards reducing the development of antibiotic resistance.

The use of antibiotics in semen extenders can contribute to the development of antibiotic resistance. The objective of the study was to evaluate epsilon-polylysine (Ɛ-PL) as a substitute for antibiotics in the buffalo semen extender. For this, 20 semen ejaculates were collected from four Murrah buffalo bulls.

Valorization potential of pine needle waste biomass: recent trends and future perspectives.

Pines play a significant role in forest biodiversity globally and generate huge forest litter. Dry pine needles due to low ignition temperature and high frictional force with the ground catch fire quickly. Annual forest fires in the northern states of India greatly impact the Indian economy besides causing huge loss to biodiversity, livelihood, and environment.

Knowledge, attitude, and practice of childhood myopia among Indian optometrists: A questionnaire-based study.

Purpose: To investigate the knowledge of myopia and its natural history including complications and clinical approaches for management adopted by optometrists across India.

Methods: An online survey was distributed to Indian optometrists. A pre-validated questionnaire was adopted from previous literature.

Enhanced lignin degradation of paddy straw and pine needle biomass by combinatorial approach of chemical treatment and fungal enzymes for pulp making.

Paddy straw (PS) and pine needles (PN) are one of the challenging biomasses in terms of disposal and compost making due to their high silica and tannin contents. Particulate air pollution, loss of biodiversity and respiratory impairments are some of disastrous outcomes caused by burning. However, high percentage of cellulose and hemicellulose makes them potential substrate for paper and pulp industries.

Aflatoxins in Cereals and Cereal-Based Products: Occurrence, Toxicity, Impact on Human Health, and Their Detoxification and Management Strategies.

Cereals and cereal-based products are primary sources of nutrition across the world. However, contamination of these foods with aflatoxins (AFs), secondary metabolites produced by several fungal species, has raised serious concerns. AF generation in innate substrates is influenced by several parameters, including the substrate type, fungus species, moisture content, minerals, humidity, temperature, and physical injury to the kernels.

Nivalenol Mycotoxin Concerns in Foods: An Overview on Occurrence, Impact on Human and Animal Health and Its Detection and Management Strategies.

Mycotoxins are secondary metabolites produced by fungi that infect a wide range of foods worldwide. Nivalenol (NIV), a type B trichothecene produced by numerous species, has the ability to infect a variety of foods both in the field and during post-harvest handling and management. NIV is frequently found in cereal and cereal-based goods, and its strong cytotoxicity poses major concerns for both human and animal health.

Citrinin Mycotoxin Contamination in Food and Feed: Impact on Agriculture, Human Health, and Detection and Management Strategies.

Citrinin (CIT) is a mycotoxin produced by different species of , , and . CIT can contaminate a wide range of foods and feeds at any time during the pre-harvest, harvest, and post-harvest stages. CIT can be usually found in beans, fruits, fruit and vegetable juices, herbs and spices, and dairy products, as well as red mold rice.

Trichothecenes in food and feed: Occurrence, impact on human health and their detection and management strategies.

Trichothecenes (TCNs) are the mycotoxins produced by many fungal species such as Fusarium, Myrothecium, and Stachybotrys and pose a considerable health risk. Based on their characteristic functional moieties, they are divided into four categories: Type A (T-2, HT-2, diacetoxyscirpenol (DAS), harzianum A, neosolaniol (NEO) and trichodermin), Type B (deoxynivalenol (DON), nivalenol (NIV), trichothecin and fusarenon X), Type C (crotocin) and Type D (satratoxin G & H, roridin A and verrucarin A) with types A and B being the most substantial. TCNs cause growth retardation in eukaryotes, suppress seedling growth or regeneration in plants and could be a reason for animal reproductive failure.

Accurate Quantification of Overlapping Herpesvirus Transcripts from RNA Sequencing Data.

Herpesviruses employ extensive bidirectional transcription of overlapping genes to overcome length constraints on their gene product repertoire. As a consequence, many lytic transcripts cannot be measured individually by reverse transcription-quantitative PCR (RT-qPCR) or conventional RNA sequencing (RNA-seq) analysis. A.

Post-traumatic bilateral vesicocutaneous fistula of thighs treated with buccal mucosa graft urethroplasty and cyanoacrylate glue instillation: a novel treatment for management of a complicated fistula.

Post-traumatic vesicocutaneous fistula (VCF) is a rare variant of urinary fistulas. These fistulas may externally communicate to abdomen, perineum, buttocks, scrotum or very rarely thigh. These fistulas usually develop at a variable time duration after trauma and are usually preceded with thigh swelling or abscess formation followed by spontaneous rupture.
