Microbial infections of various types of wounds are a challenge to the treatment of wounds and wound healing. The aim of the study is to determine the antimicrobial, antioxidant, and in vivo wound healing properties of methanol leaf extracts of Justicia flava and Lannea welwitschii. The antimicrobial activity was investigated using agar well diffusion and microdilution methods. The free radical...

Regional genetic differentiation within species is often addressed in evolutionary ecology and conservation biology. Here, we address regional differentiation in two closely related hybridizing taxa, the perennial sedges Carex flava and C. viridula and their hybrid C. × subviridula in 37 populations in the north and centre of their distribution range in Europe (Estonia, Lowland (<1000 m a.s.l.)...

The effect of the application of 1-methylcyclopropene (1-MCP) and wax emulsions, alone or combined, on composition analysis, vitamin C, polyphenols, and antioxidant capacity of soursop was evaluated. Fruits were stored as follows: at 25 °C (control), and at 16 °C: fruits sprayed with candelilla or flava emulsions, fruits treated with 1500 nL/L of 1-MCP (20 °C, 12 h), and fruits treated with 1-M...

The altitudinal range of the aridland herbaceous perennial Cryptantha flava overlaps with the wintering range of mule deer (Odocoileous hemionus ) in the Colorado Plateau region of the western United States. Deer do not feed on C. flava , but do influence its microhabitat via excretion of nitrogenous compounds. We were interested in determining the importance of Mule deer in redistributing N ac...

The genus Carex belongs to tribe Cariceae, subfamily Caricoideae and family Cyperaceae. This genus, with about 2000 species in the world and more than 50 species in Iran, is the largest genus among the family. In expedition to North West and West of Iran, two species, namely, Carex acuta and C. cilicica as new records and C. flava, C. rostrata and C. supina as reinvestigated species are reporte...

We studied the floral biology of five North American members of Oenothera L. sect. Lavauxia (Spach) Endl. (Onagraceae L.) in field and common greenhouse settings. Oenothera sect. Lavauxia floral morphology ranges from small, cleistogamous flowers (O. flava subsp. flava (A. Nels.) Garrett in Garrett) to some of the longest-tubed flowers in North America (O. flava subsp. taraxacoides (Wooton & St...

The ligamenta flava, together with the vertebral lamina, form the posterior wall of the spinal canal. Since they are located immediately adjacent to the nerve structures of the spinal cord, every pathology that involves hypertrophy produces neurological disturbances as a result. One of the most common reasons for hypertrophy of the ligamenta flava is heterotopic ossification. The main regions o...
