Circadian-based approach for improving physiological, phytochemical and chloroplast proteome in Spinacia oleracea under salinity stress and light emitting diodes.

Salt stress is a recognized annihilating abiotic stress that has a significant impact on agricultural and horticulture crop productivity. Plant development faces three distinct dangers as a result of salt stress: oxidative stress, osmotic stress, and ionic toxicity. It has been shown that plants can forecast diurnal patterns using the circadian clock; moreover, they can manage their defensive mechanism for the detoxification of reactive oxygen species (ROS).

Multiobjective optimization of membrane in hybrid cryogenic CO separation process for coal-fired power plants.

Post-combustion carbon dioxide (CO) capture is considered a potential method to mitigate CO emissions from fossil fuels burned in power plants. In recent years, combining two different methods of post-combustion CO capture such as membrane and cryogenic distillation has been explored for availing the advantages of each method. This study focuses on the optimization of membranes for developing the membrane-cryogenic distillation process.

Regulation of EMT Markers, Extracellular Matrix, and Associated Signalling Pathways by Long Non-Coding RNAs in Glioblastoma Mesenchymal Transition: A Scoping Review.

Glioblastoma (GBM) mesenchymal (MES) transition can be regulated by long non-coding RNAs (lncRNAs) via modulation of various factors (Epithelial-to-Mesenchymal (EMT) markers, biological signalling, and the extracellular matrix (ECM)). However, understanding of these mechanisms in terms of lncRNAs is largely sparse. This review systematically analysed the mechanisms by which lncRNAs influence MES transition in GBM from a systematic search of the literature (using PRISMA) performed in five databases (PubMed, MEDLINE, EMBASE, Scopus, and Web of Science).

Conserved functions of hypothalamic kisspeptin in vertebrates.

Hypothalamic kisspeptin encoded by KISS1/Kiss1 gene emerged as a regulator of the reproductive axis in mammals following the discovery of the kisspeptin receptor (Kissr) and its role in reproduction. Kisspeptin-Kissr systems have been investigated in various vertebrates, and a conserved sequence of kisspeptin-Kissr has been identified in most vertebrate species except in the avian linage. In addition, multiple paralogs of kisspeptin sequences have been identified in the non-mammalian vertebrates.

Hypothalamic kisspeptin and kisspeptin receptors: Species variation in reproduction and reproductive behaviours.

Kisspeptin, encoded by the KISS1 gene, was first discovered as a potential metastasis suppressor gene. The prepro-kisspeptin precursor is cleaved into shorter mature bioactive peptides of varying sizes that bind to the G protein-coupled receptor GPR54 (=KISS1R). Over the last two decades, multiple types of Kiss and KissR genes have been discovered in mammalian and non-mammalian vertebrate species, but they are remarkably absent in birds.

Primary Synovial Sarcoma of the Orbit: A Case Report and Update on Diagnostic Techniques.

Synovial sarcoma is a malignant mesenchymal tumor that most commonly occurs in the deep soft tissue of the extremities in adolescents and young adults. Primary periocular synovial sarcoma is extremely rare with only 11 previously reported cases. We describe a 23-year-old woman who presented with a 1-year history of painful, progressive right upper eyelid swelling.

Exenteration and Adjuvant Radiotherapy for Primary Carcinosarcoma of the Anterior Orbit: A Case Report.

Carcinosarcoma is a malignant mixed tumor composed of epithelial and mesenchymal components which arises in a variety of tissues, including, in rare cases, the orbit. A 75-year-old male with a history of basal cell carcinoma of the left medial canthus, previously treated with surgical resection and adjuvant radiation therapy, presented with a recurrent 3 cm nodule of the left medial canthus. He underwent surgical resection of the left superior and inferior eyelid with pathology revealing invasive squamous cell carcinoma of upper and lower eyelids with deep orbital tissue involvement and undifferentiated pleomorphic sarcoma involving the dermis and periosteum, consistent with carcinosarcoma.

Habenula kisspeptin retrieves morphine impaired fear memory in zebrafish.

The habenula is an evolutionarily conserved brain structure, which has recently been implicated in fear memory. In the zebrafish, kisspeptin (Kiss1) is predominantly expressed in the habenula, which has been implicated as a modulator of fear response. Hence, in the present study, we questioned whether Kiss1 has a role in fear memory and morphine-induced fear memory impairment using an odorant cue (alarm substances, AS)-induced fear avoidance paradigm in adult zebrafish, whereby the fear-conditioned memory can be assessed by a change of basal place preference (= avoidance) of fish due to AS-induced fear experience.

Purpose: To evaluate the effect of physician face mask use on rates and outcomes of postinjection endophthalmitis.

Design: Retrospective, comparative cohort study.

Methods: Setting: Single-center.

Mapping of Morphine-Induced Gene Expression Pattern in the Adult Zebrafish Brain.

Morphine is a potent analgesic opiate commonly used in treating pain, and it is also a substance of abuse and highly addictive. Hence, it is vital to discover the action sites of morphine in the brain to increase its efficacy of treatment. In the present study, we aimed at identifying comprehensive neuroanatomical locations that are sensitive to morphine in the adult zebrafish ().

Distribution of Kiss2 receptor in the brain and its localization in neuroendocrine cells in the zebrafish.

Kisspeptin is a hypothalamic neuropeptide, which acts directly on gonadotropin-releasing hormone (GnRH)-secreting neurons via its cognate receptor (GPR54 or Kiss-R) to stimulate GnRH secretion in mammals. In non-mammalian vertebrates, there are multiple kisspeptins (Kiss1 and Kiss2) and Kiss-R types. Recent gene knockout studies have demonstrated that fish kisspeptin systems are not essential in the regulation of reproduction.
