Development of transgenic lines from a male-sterile potato variety, with potential resistance to tecia solanivora povolny
(Universidad Nacional de Colombia, Facultad de Agronomía, Centro Editorial, 2012)
Male sterility is a very important characteristic for environmental safety in genetically modified (GM) plants, particularly in the release of transgenic plants in the centers of origin or high biodiversity areas. In order ...
Carcinoma espinocelular en hospitales públicos de la Región Metropolitana de Chile:análisis de la localización anátomica, género y edad
(Hospital Clínico Universidad de Chile, 2010)
Cutaneous squamous cell carcinoma (SCC) is the second most common skin cancer; its incidence is increasing in the last decades worldwide. The purpose of this study was to analyze 1320 SCC (716 males and 604 females) from ...
Alary polymorphism in Triatoma spinolai and its possible relationship with demographic strategy
(1998)
Among collections of Triatoma spinolai from various sites in northern Chile, adults from coastal populations are invariably wingless, whereas inland populations show balanced alary polymorphism between wingless females and ...
Sex differences, alcohol dehydrogenase, acetaldehyde burst, and aversion to ethanol in the rat: a systems perspective
(AMER PHYSIOLOGICAL SOC, 2007-08)
Sex differences, alcohol dehydrogenase, acetaldehyde burst, and aversion to ethanol in the rat: a systems perspective. Individuals who carry the most active alcohol dehydrogenase (ADH) isoforms are protected against ...
Home sweet home: social dynamics and genetic variation of a long-term resident bottlenose dolphin population off the chilean coast
(Elsevier, 2018-05)
Coastal resident and pelagic nonresident bottlenose dolphins, Tursiops truncatus, have been described in north-central Chile. Using long-term residence data (over 13 years of photo-identification) and genetic mtDNA ...
An abnormal terminal X-Y interchange accounts for most but not all cases of human XX maleness
(1987)
To determine if human XX maleness results from an abnormal chromosomal X-Y interchange, we studied the inheritance of the paternal pseudoautosomal region in nine patients. Those six patients in whom Y-specific DNA was found ...
Evaluation of permethrin for attracticide development against Choristoneura rosaceana and Pandemis pyrusana (Lepidoptera : Tortricidae) males
(ELSEVIER, 2006-09)
The behavioural effects on Choristoneura rosaceana Harris and Pandemis pyrusana Kearfott male moths of permethrin added into a grease matrix containing the female sex pheromone for each species (i.e. an attracticide) were ...
BRDT is an essential epigenetic regulator for proper chromatin organization, silencing of sex chromosomes and crossover formation in male meiosis
(Public Library Science, 2018)
The double bromodomain and extra-terminal domain (BET) proteins are critical epigenetic
readers that bind to acetylated histones in chromatin and regulate transcriptional activity
and modulate changes in chromatin structure ...
Puberty arises with testicular alterations and defective AMH expression in rams prenatally exposed to testosterone
(Elsevier, 2017)
The male gonadal tissue can be a sensitive target to the reprogramming effects of testosterone (T) during prenatal development. We have demonstrated that male lambs born to dams receiving T during pregnancy-a model system ...
Independence of evoked vocal responses from stimulus direction in burrowing frogs Eupsophus (Leptodactylidae)
(2007)
Localization of a sound source is important for animals in mating contexts: females generally orient towards signalling males, and males can estimate the position and quality of potential rivals. In anurans, the effect of ...
