Clonostachys rosea (Link: Fries) Schroers, Samuels, Seifert, and Gams (Ascomycota: Hypocreales) has been reported as a mycoparasite of fungi and nematodes and as saprobe in soils, but this fungus has not been reported previously to be entomopathogenic. Many species of cicadellid leafhoppers cause economic damage to crops as vectors of plant pathogens. In the present work, we report the first re...

Rhizophlyctis rosea (Chytridiomycota) is an apparently ubiquitous, soil-inhabiting, cellulose-degrading chytrid that is the type for Rhizophlyctis. Previous studies have revealed multiple zoospore subtypes among morphologically indistinguishable isolates in the R. rosea complex sensu Barr. In this study we analysed zoospore ultrastructure and combined nu-rRNA gene sequences (partial LSU and com...

The distribution and abundance of mosquito larvae in a freshwater marsh were determined during a low water period in the late summer. Culex tarsalis larval abundance was significantly associated with the percent cover by Typha spp. root masses and Typha spp. stem density in 1-m2 quadrants. Larval mosquito abundance was not significantly related to bulrush (Scirpus californicus) stem density, po...

Rhodiola rosea, a medicinal plant with demonstrated adaptogenic properties, has recently been reported to contain active compounds with antimicrobial activity. The goal of this study was to measure the antiviral and antibacterial properties of the bioactive metabolites of Rhodiola rosea in the serum of experienced marathon runners following supplementation. Marathon runners, randomly divided in...

OBJECTIVE To detect temporal case clustering in patients with pityriasis rosea in different geographic locations. DESIGN Regression analysis of dates on which 1379 patients were diagnosed as having pityriasis rosea in 3 different geographic locations. The control data consisted of dates of diagnosis of patients with psoriasis in the same settings. SETTING Dermatology clinics in Kuwait, Minn...

Administration of aqueous extracts of V. rosea flower and leaf have been found to regulate the blood sugar level in alloxan diabetic male albino rats. V. rosea therapy not only produced blood glucose homeostasis but also reversed changes in carbohydrate, protein, lipid metabolisms and metabolic and pathologic changes that took place in pancreatic islet cells, liver and kidney following a single...

OBJECTIVE To investigate the pretreatment effects of Rhodiola rosea (R. rosea) extract on cognitive dysfunction, oxidative stress in hippocampus and hippocampal neuron injury in a rat model of Alzheimer's disease (AD). METHODS Male Sprague-Dawley rats were pretreated with R. rosea extract at doses of 1.5, 3.0, and 6.0 g/kg for 3 weeks, followed by bilateral intracerebroventricular injection w...

BACKGROUND Pityriasis rosea is an acute, self-limiting disease, probably infective in origin, affecting mainly children and young adults, characterized by distinctive skin eruptions and minimal constitutional symptoms. Both oral Erythromycin and oral Acyclovir have been used in its management. OBJECTIVES To compare the effectiveness of oral Erythromycin and oral Acyclovir in the treatment of ...

In the present study aqueous extract of Piper nigrum seeds and Vinca rosea flowers were administered orally to alloxan induced diabetic rats once a day for 4 weeks. These treatments lead to significant lowering of blood sugar level and reduction in serum lipids. The levels of antioxidant enzymes, catalase and glutathione peroxidase decreased in alloxan induced diabetic rats however these levels...

Sir, A 74-year-old female patient treated with angiotensin-converting enzyme inhibitor for arterial hypertension metformin and atorvastatin insulin-independent diabetes mellitus hyperlipidemia, respectively, consulted the outpatient dermatological clinic a rash that appeared fifteen days prior to consultation. The received second dose of mRNA COVID-19 vaccine on July 29, 2021, was due receive t...
