Euphorbia hirta Linn. (Euphorbiaceae), commonly known as ‘Dudhy’ is an annual medicinal herb of Kumaun Himalaya Uttarakhand. It is an invasive plant used in conventional medicine to treat various diseases such as gastrointestinal disorders, respiratory system disorders, and asthma. The present review is designed with the aim to compile updated information on E. hirta including its medicinal uses, phytochemicals, as well as biological activities. Qualitative and quantitative phytochemical studies on E. hirta revealed the presence of various chemical compounds in which flavonoids, terpenoids and phenols are the major constituents. These monomeric compounds and crude extracts from E. hirta have also been screened for pharmacological activities in-vivo and in-vitro. Different parts of the plant have interesting antimicrobial, antioxidant, antidiabetic, and antitumor properties. Some traditional uses of this plant, such as in gastrointestinal disorder, bronchitis, and in asthma, also indicated its high medicinal potentiality. E. hirta has been proved a valuable medicinal plant for the tribal people living in the rural region of Kumaun Himalaya. The crude hydro-alcoholic extract of E....

A new series of Schiff’s base compounds were synthesized by condensation of 1-(4-amino-4 phenyl) 3-phenyl triazene-1-ol) and substituted aldehyde and gave high yields of target compounds. Antimicrobial activity of compounds has been tested against bacterial and fungal species, namely gram-positive bacteria as S. aureus and S. pyogenes, gram-negative bacteria as E. coli and P. aeruginosa, and fungal species C. albicans and A. clavatus are selected based on their clinical and pharmacological importance. Bacterial and fungal tests were performed under the same conditions using Cefixime and Griseofulvin as standard drugs. It has been found that synthesized Schiff’s base has shown efficient antibacterial and anti-fungal activities. Thus they can be revealed as potent antimicrobial compounds. They are widely used for industrial purposes and also exhibit a broad range of biological activities. The structures of synthesized compounds were confirmed by TLC, melting point, Infrared spectroscopy, and proton nuclear magnetic resonance spectroscopy (1HNMR)...

An extensive range of studies have shown plant extracts and their phyto-constituents efficacy, proposing them as a promising alternative for treatment or as adjuvants in human diseases such in skin, gastrointestinal, systemic and dental conditions, due to various active components presence, ease of access and reduced side effects. Indeed, depending on solvent used to obtain the extract, its active molecules may vary, including flavonoids, tannins, alkaloids, terpenes, sesquiterpenes, sterols, among others. Extract content (crude/partition/fraction) has pharmacological advantages over isolated compounds, due to pleiotropic activity and synergistic effect between components. Due to factors such as low bioavailability, solubility, and stability, it is difficult to translate its in-vitro and in-vivo effects into clinical picture, besides that pharmacological effects full potential cannot be exploited. However, in recent decades, extraordinary advances have been made in new drug delivery systems for the encapsulation of active plant metabolites, thus helping to improve different medicinal plant-based therapies and product efficacy. The current review highlights the importance of nanocarriers loaded with plant extracts as an alternative for dental, dermatological, gastrointestinal,...

Positron emission tomography (PET) imaging has been broadly used in the study of brain damage for a long time. However, PET has been mostly used for the assessment and detection of neural activity after brain damage. Tau proteins play a significant role in a variety of degenerative neurological conditions. Post-mortem neuropathology studies of victims of repeated and severe head trauma have defined a unique spatial expression of neurological tauopathies in these individuals known as chronic traumatic encephalopathy (CTE). The current review assesses the role of tau in head injury, the state of tau radiotracer development, and the potential clinical value of tau-PET derived from head injury studies. There are variations in the binding patterns between different tau radiotracers. Therefore, the present work is commenced with a general review of TBI and CTE, followed by the chronic and acute pathophysiological consequences of TBI. In the following, beta-amyloid, glycolysis, and tau protein radiotracers are assessed critically, considering the most recent and available imaging studies. Considering the scientific relevance of these radiotracers...
