Beyond conventional therapy: NOX4 as a promising target in cardiomyopathy.

Cardiomyopathy refers to disorders marked by structural and functional irregularities in the heart muscle, occurring independently of other conditions that might explain these abnormalities. The most common types are dilated and hypertrophic cardiomyopathies, while Takotsubo, restrictive, left ventricular non-compaction, and arrhythmogenic right ventricular cardiomyopathies are rarer. These conditions cause ventricular hypertrophy, fibrosis, myocardial dysfunction, and chamber dilation due to responses to stressors such as pressure overload, myocardial infarction, inflammation, diabetes, and cardiotoxic drugs.

Cataract Extraction After Brachytherapy for Malignant Melanoma of the Choroid in a Young Female Patient: A Case Report.

The use of brachytherapy, a form of radiation therapy, plays a crucial role in the management of intraocular melanomas of the choroid. Ionization radiation treatment has the unfortunate side effect of developing cataracts prematurely. We present an uncommonly seen case of a 36-year-old woman who presented with blurred vision in her left eye following successful plaque radiotherapy four years prior for malignant melanoma in the same eye.

Resistance development in pink bollworm (Pectinophora Gossypiella Saunders) against Bt cotton and its' establishment as mid season pest in India.

The pink boll worm now became a menace for sustainable cultivation of Bt cotton in India. Based on the data recorded in unsprayed conditions at 13 different locations of north, central and south cotton growing zone between 2007 and 2023, initiation of green boll damage during later part of the season was observed on Bt cotton genotype during 2009-2014 wherein incidence of PBW already existed on non-Bt genotype. In our research, between 2014 and 2017, the central and southern regions of India experienced a rise in the survival of pink bollworms on Bt cotton surpassing the Economic Threshold Level (ETL) whereas in the north zone PBW incidence started in 2018 at experimental locations.

Odor prediction of whiskies based on their molecular composition.

Aroma compositions are usually complex mixtures of odor-active compounds exhibiting diverse molecular structures. Due to chemical interactions of these compounds in the olfactory system, assessing or even predicting the olfactory quality of such mixtures is a difficult task, not only for statistical models, but even for trained assessors. Here, we combine fast automated analytical assessment tools with human sensory data of 11 experienced panelists and machine learning algorithms.

Decellularised plant scaffolds facilitate porcine skeletal muscle tissue engineering for cultivated meat biomanufacturing.

Cultivated meat (CM) offers a sustainable and ethical alternative to conventional animal agriculture, involving cell maturation in a controlled environment. To emulate the structural complexity of traditional meat, the development of animal-free and edible scaffolds is crucial, providing vital physical and biological support during tissue development. The aligned vascular bundles of the decellularised asparagus scaffold were selected to facilitate the attachment and alignment of murine myoblasts (C2C12) and porcine adipose-derived mesenchymal stem cells (pADMSCs).

Classification of substances by health hazard using deep neural networks and molecular electron densities.

In this paper we present a method that allows leveraging 3D electron density information to train a deep neural network pipeline to segment regions of high, medium and low electronegativity and classify substances as health hazardous or non-hazardous. We show that this can be used for use-cases such as cosmetics and food products. For this purpose, we first generate 3D electron density cubes using semiempirical molecular calculations for a custom European Chemicals Agency (ECHA) subset consisting of substances labelled as hazardous and non-hazardous for cosmetic usage.

Pneumothorax Secondary to a Traumatic Brazilian Jiu-Jitsu Injury.

A pneumothorax is a medical condition characterized by the presence of free air in the pleural cavity. Pneumothorax can be classified as spontaneous, traumatic, or iatrogenic. Spontaneous pneumothorax sustained from a jiu-jitsu-induced blunt trauma has not been described in any sports literature.

Nanoparticle-Shielded dsRNA Delivery for Enhancing RNAi Efficiency in Cotton Spotted Bollworm (Lepidoptera: Nolidae).

The spotted bollworm (Lepidoptera: Nolidae) is a polyphagous pest with enormous economic significance, primarily affecting cotton and okra. However, the lack of gene sequence information on this pest has a significant constraint on molecular investigations and the formulation of superior pest management strategies. An RNA-seq-based transcriptome study was conducted to alleviate such limitations, and de novo assembly was performed to obtain transcript sequences of this pest.

OWSum: algorithmic odor prediction and insight into structure-odor relationships.

We derived and implemented a linear classification algorithm for the prediction of a molecule's odor, called Olfactory Weighted Sum (OWSum). Our approach relies solely on structural patterns of the molecules as features for algorithmic treatment and uses conditional probabilities combined with tf-idf values. In addition to the prediction of molecular odor, OWSum provides insights into properties of the dataset and allows to understand how algorithmic classifications are reached by quantitatively assigning structural patterns to odors.

Novel application of intravascular lithotripsy in stent under-expansion: A single-center experience.

Introduction: Stent under-expansion due to calcification is associated with a less durable result. The development of intravascular lithotripsy (IVL) has provided clinicians with a readily available, simple-to-use treatment option for coronary calcification, but the use of IVL within a previously stented segment is currently off-license. There are, however, developing data suggesting that the use of IVL can be an effective treatment option for patients with calcific stent under-expansion.

Unified trade-off optimization of quantum harmonic Otto engine and refrigerator.

We investigate quantum Otto engine and refrigeration cycles of a time-dependent harmonic oscillator operating under the conditions of maximum Ω function, a trade-off objective function which represents a compromise between energy benefits and losses for a specific job, for both adiabatic and nonadiabatic (sudden) frequency modulations. We derive analytical expressions for the efficiency and coefficient of performance of the Otto cycle. For the case of adiabatic driving, we point out that in the low-temperature regime, the harmonic Otto engine (refrigerator) can be mapped to Feynman's ratchet and pawl model which is a steady-state classical heat engine.

CRISPR/Cas tool designs for multiplex genome editing and its applications in developing biotic and abiotic stress-resistant crop plants.

Crop plants are prone to several yield-reducing biotic and abiotic stresses. The crop yield reductions due to these stresses need addressing to maintain an adequate balance between the increasing world population and food production to avoid food scarcities in the future. It is impossible to increase the area under food crops proportionately to meet the rising food demand.

Endotracheal inflammatory myofibroblastic tumour: A rare cause of central airway occlusion in adults.

Inflammatory myofibroblastic tumour (IMT) is an unusual myofibroblastic spindle cell neoplasm that is rarely discovered in the airway of adults. Previously, it was regarded as a reactive lesion and was infamously known as inflammatory pseudotumour before recent insights revealed that significant majority of cases harboured neoplastic genes. Diagnosis is difficult as clinical presentation and imaging findings are non-specific.

Introgressing cry1Ac for Pod Borer Resistance in Chickpea Through Marker-Assisted Backcross Breeding.

The gram pod borer is a major constraint to chickpea ( L.) production worldwide, reducing crop yield by up to 90%. The constraint is difficult to overcome as chickpea germplasm including wild species either lacks pod borer resistance or if possessing resistance is cross-incompatible.
