Background: Bitter gourd requires well-drained sandy to sandy loam soils for optimum growth, development, and germination, while its growth is retarded in extreme saline conditions. It is very sensitive to salinity stress, which imposes devastating limits on its productivity. Thus, the impact of soil salinization on the economics of bitter gourd yield deserves scientific inquiry.

Cellular mechanical dysregulation can lead to diseases and conditions like tumorigenesis. Drug delivery systems that recognize and respond to specific cellular mechanical characteristics are potentially useful for targeted therapy. We report here the creation of a DNA mechanical nanovehicle that is responsive to cell surface receptor-mediated tensile forces, which can then correspondingly deliver an anticancer drug in situ.

Duchenne's muscular dystrophy (DMD) is a severe X-linked disorder characterized by progressive muscle degeneration, leading to loss of ambulation, respiratory failure, and premature death. It affects approximately 1 in 3,500 live male births and is caused by mutations in the dystrophin gene, which impairs muscle fiber stability. Current treatments are limited to managing symptoms and slowing disease progression, with no curative therapies available.

Article Synopsis
  • High-energy X-ray diffraction methods can analyze the 3D microstructure of metals without damaging them, often under conditions like heat or pressure to observe changes over time.
  • Traditional methods for analyzing the resulting data are slow and costly, making it difficult to quickly extract useful information.
  • A new fully automated technique improves data analysis speed by at least 50 times and can work with sparser datasets, using advanced image learning to identify important changes in the microstructure more efficiently.

Protein malnutrition is a major public health concern in the developing world. The livestock products are a good source of high-quality protein, but the livestock industry is a source of pollution and one of the leading causes of climate change because the slaughtering of animals results in the accumulation of waste, offals, and several inedible body portions. The rapid increase in the human population and inadequate supply of traditional protein sources have driven a search for novel and alternative protein sources such as edible insects.

Hydrophilic drugs could be incorporated into the skin surface by manes of Lipogel. This study aimed to prepare miconazole lipogel with natural ingredients to enhance drug permeability using dimethyl Sulfoxide (DMSO). The miconazole lipogels, A1 (without DMSO) and A2 (with DMSO) were formulated and evaluated for organoleptic evaluation, pH, viscosity, stability studies, freeze-thawing, drug release profile and drug permeation enhancement.

Cell-generated forces are a key player in cell biology, especially during cellular shape formation, migration, cancer development, and immune response. A new type of label-free smartphone-based electrochemical DNA sensor is developed here for cellular force measurement. When cells apply tension forces to the DNA sensors, the rapid rupture of DNA duplexes allows multiple redox reporters to reach the electrode and generate highly sensitive electrochemical signals.

The increased sensation error between the surroundings and the driver is a major problem in driving simulators, resulting in unrealistic motion cues. Intelligent control schemes have to be developed to provide realistic motion cues to the driver. The driver's body model incorporates the effects of vibrations on the driver's health, comfort, perception, and motion sickness, and most of the current research on motion cueing has not considered these factors.

Cytarabine, an antimetabolite antineoplastic agent, has been utilized to treat various cancers. However, because of its short half-life, low stability, and limited bioavailability, achieving an optimal plasma concentration requires continuous intravenous administration, which can lead to toxicity in normal cells and tissues. Addressing these limitations is crucial to optimize the therapeutic efficacy of cytarabine while minimizing its adverse effects.

Cells continuously experience and respond to different physical forces that are used to regulate their physiology and functions. Our ability to measure these mechanical cues is essential for understanding the bases of various mechanosensing and mechanotransduction processes. While multiple strategies have been developed to study mechanical forces within two-dimensional (2D) cell culture monolayers, the force measurement at cell-cell junctions in real three-dimensional (3D) cell models is still pretty rare.
