Background: Sex chromosomes have evolved independently multiple times in eukaryotes and are therefore considered a prime example of convergent genome evolution. Sex chromosomes are known to emerge after recombination is halted between a
Castration of the male lizard Amphibolurus ornatus results in atrophy of the femoral glands. The amount of secretion collected from glands decreased from (mean +/- SE) 136.6 +/- 13.0 micrograms/g body wt prior to castration to 102.7 +/- 14.6 micrograms/g body wt 28 days after castration (P less than
BACKGROUND
Captive Andean bears (Tremarctos ornatus) develop a distinct alopecic syndrome of unknown aetiology.
OBJECTIVE
To describe the histological features of healthy Andean bear skin, to define the clinical and histopathological features of Andean bears with signs of alopecia, and to propose an
Hepatic lesions in 4 field cases of ovine hepatogenous photosensitization caused by the plant, Asaemia axillaris (Thunb.) Harv. Ex Jackson, are described. The liver was usually swollen, friable and yellowish-brown, with distinct lobulation. Microscopically, the lesions ranged from peripheral
BACKGROUND
Mosquitoes are well known as vectors of several disease causing pathogens. The extensive use of synthetic insecticides in the mosquito control strategies resulted to the development of pesticide resistance and fostered environmental deterioration. Hence in recent years plants become
Sex chromosomes can evolve when recombination is halted between a pair of chromosomes, and this can lead to degeneration of the sex-limited chromosome. In the early stages of differentiation sex chromosomes are homomorphic, and even though homomorphic sex chromosomes are very common throughout
OBJECTIVE
To observe the unique structural features of chicken calamus keratin (CCK) conduit as a candidate scaffold material for tissue engineering and its in vivo degradation and histocompatibility after its implantation into living tissues.
METHODS
Chicken calami were taken from healthy chickens
This study was designed to investigate the therapeutic potential of hydroalcoholic extracts of Acorus calamus (AC) in tibial and sural nerve transection (TST)-induced neuropathic pain in rats. The hot plate, paw heat allodynia, acetone drop, and pinprick tests were performed to assess the degree of
Effect of the essential oil of Acorus calamus L. rhizomes, was studied on hemocytes of the tobacco armyworm, Spodoptera litura. The oil was administered in oral application at concentration of 500 and 1000 ppm to last instar larvae of S. litura and its effect on ultrastructure of hemocytes and
Background:Acorus calamus (Sweet flag) is a known herbal drug commonly used in traditional medicine. Our aim was to perform seasonal and altitudinal phytochemical screening to assess the antioxidant activity of the essential oils in the rhizome and leaves of A. calamus from three different
In the following, we report our findings obtained as a result of injecting an acrylic pigment in the arteries supplying the pectoralis minor muscle in 50 lateral chests of 26 Japanese adults (15 males and 11 females). In the pectoralis minor muscle, the muscular bundle near the terminal is supplied
The value of fluctuating asymmetry is considered to be an indicator of the developmental instability of the organism. The consequences of activities of the mining industry plants, which are characterized by alienation and transformation of large areas of natural landscapes, are analyzed as an
Our aim was to present and analyze age-related changes of peripheral nerves and muscles of limbs on a huge population of healthy persons of different ages. Persons aged from 2 months to 87 years were studied by conduction studies (EMG) during the period 2009-2016 years in Scientific Research
The possible origins and differentiation of a ZZ/ZW sex chromosome system in Semaprochilodus taeniurus, the only species of the family Prochilodontidae known to possess heteromorphic sex chromosomes, were examined by conventional (C-banding) and molecular (cross-species hybridization of W-specific
