Plants are an important source of food, energy, and bioproducts. Advances in genetics, genomics-assisted breeding, and biotechnology have facilitated the combining of desirable traits into elite cultivars. To ensure sustainable crop production in the face of climate challenges and population growth, it is essential to develop and implement techniques that increase crop yield and resilience in environments facing water scarcity, nutrient deficiencies, and other abiotic and biotic stressors.

Arsenic (As), a naturally occurring element with unique properties, has been recognized as the largest mass poisoning in the world by the World Health Organization (WHO). Approximately 200 million people worldwide are exposed to toxic levels of arsenic due to natural and anthropogenic activities. This widespread exposure necessitates a deeper understanding of microbe-arsenic interactions and their potential influence on host exposure and health risks.

Biomass crops engineered to accumulate energy-dense triacylglycerols (TAG or 'vegetable oils') in their vegetative tissues have emerged as potential feedstocks to meet the growing demand for renewable diesel and sustainable aviation fuel (SAF). Unlike oil palm and oilseed crops, the current commercial sources of TAG, vegetative tissues, such as leaves and stems, only transiently accumulate TAG. In this report, we used grain (Texas430 or TX430) and sugar-accumulating 'sweet' (Ramada) genotypes of sorghum, a high-yielding, environmentally resilient biomass crop, to accumulate TAG in leaves and stems.

This case report introduces a novel modification in the space-regaining process using a nickel-titanium (NiTi) open coil spring in a five-year-old male patient with early primary molar loss. The space deficiency, which led to occlusal discrepancies such as posterior crossbite, was efficiently managed using the NiTi wire and open coil spring, which is known for its superelasticity. The modification involved the use of a NiTi open coil spring, enabling effective space regaining and stabilization with band and loop space maintainers.

We present three cases for the management of paediatric tongue tie (ankyloglossia) through laser-assisted frenectomy and postoperative oral myofunctional exercises. Ankyloglossia, characterised by a restricted lingual frenulum, poses challenges in tongue movement and is traditionally treated with surgical interventions. Laser technology, particularly diode lasers, has shown promise in paediatric cases due to reduced bleeding, minimal discomfort and faster recovery.

Each cargo in a cell employs a unique set of motor proteins for its transport. To dissect the roles of each type of motor, we developed optogenetic inhibitors of endogenous kinesin-1, -2, -3 and dynein motors and examined their effect on the transport of early endosomes, late endosomes, and lysosomes. While kinesin-1, -3, and dynein transport vesicles at all stages of endocytosis, kinesin-2 primarily drives late endosomes and lysosomes.

The human body constantly experiences mechanical loading. However, quantifying internal loads within the musculoskeletal system remains challenging, especially during unconstrained dynamic activities. Conventional measures are constrained to laboratory settings, and existing wearable approaches lack muscle specificity or validation during dynamic movement.

Objective: The main aim of this present systematic review is to evaluate if the preservation of pericervical dentin (PCD) increases the fracture resistance of endodontically treated permanent posterior teeth.

Materials And Methods: Two independent reviewers conducted a comprehensive review of all published studies from 2007 (1/1/2007) to 2023 (31/5/23) since the concept of PCD first appeared in the literature in 2007. Searches were conducted in multiple electronic database engines: PubMed, Scopus, EBSCO (Dentistry and oral health sciences), Web of Sciences (WOS), Cochrane, Google Scholar and Open Grey, Ovid and Shodhganga, in addition to cross-references and hand search.

Article Synopsis
  • Hepatitis B virus (HBV) particles are composed of HBV core protein (HBV Cp) that forms double-shelled capsids, which can spontaneously assemble under specific conditions, utilizing high ionic strength.
  • Traditional methods for studying HBV capsid assembly are complex and expensive, involving techniques like light scattering and microscopy, whereas this research introduces ProCharTS, a simpler, label-free technique that monitors real-time assembly through protein charge transfer spectra.
  • The study demonstrates that ProCharTS effectively tracks capsid formation, as the absorbance and luminescence increase during assembly, and combined with fluorescence anisotropy assays, it provides a sensitive measure of capsid characteristics compared to native dimers.

Objective: Discolouration of primary teeth, often attributed to trauma and pulpal infection, is a prevalent concern that can significantly impact the esthetics and self-esteem of children. To address this issue, bleaching techniques have emerged as a viable treatment option. This systematic review aims to provide a comprehensive summary of the effectiveness of bleaching agents in managing discoloured primary teeth.

Several types of mood disorders lie along a continuum, with nebulous boundaries between them. Understanding the mechanisms that contribute to mood disorder complexity is critical for effective treatment. However, present treatments are largely centered around neurotransmission and receptor-based hypotheses, which, given the high instance of treatment resistance, fail to adequately explain the complexities of mood disorders.

Bioenergy sorghum is a low-input, drought-resilient, deep-rooting annual crop that has high biomass yield potential enabling the sustainable production of biofuels, biopower, and bioproducts. Bioenergy sorghum's 4-5 m stems account for ~80% of the harvested biomass. Stems accumulate high levels of sucrose that could be used to synthesize bioethanol and useful biopolymers if information about cell-type gene expression and regulation in stems was available to enable engineering.

Gene functional descriptions offer a crucial line of evidence for candidate genes underlying trait variation. Conversely, plant responses to environmental cues represent important resources to decipher gene function and subsequently provide molecular targets for plant improvement through gene editing. However, biological roles of large proportions of genes across the plant phylogeny are poorly annotated.

Background: Individualized, targeted, and intense training is the hallmark of successful gait rehabilitation in people post-stroke. Specifically, increasing use of the impaired ankle to increase propulsion during the stance phase of gait has been linked to higher walking speeds and symmetry. Conventional progressive resistance training is one method used for individualized and intense rehabilitation, but often fails to target paretic ankle plantarflexion during walking.
