(Sociedade Brasileira de Genética, 2009)The complete base sequence of HIV-1 virus and GP120 ENV gene were analyzed to establish their distance to the expected neutral random sequence. An especial methodology was devised to achieve this aim. Analyses included: a) ...
-
(2009)Adaptation to endoplasmic reticulum (ER) stress depends on the activation of an integrated signal transduction pathway known as the unfolded protein response (UPR). Bax inhibitor-1 (BI-1) is an evolutionarily conserved ...
-
(Endocrine Society, 2009)Context: A significant proportion of the first-degree female relatives of women with polycystic ovary syndrome (PCOS) may be at risk for developing PCOS. However, it is not known at which stage of pubertal development the ...
-
(American Academy of Sleep Medicine, 2009)Study objectives: A model of rapid eye movement (REM) sleep expression is proposed that assumes underlying regulatory mechanisms operating as inhomogenous Poisson processes, the overt results of which are the transitions ...
-
(2009)Mammalian cells sense oxygen levels and respond to hypoxic conditions through the regulation of multiple signaling pathways and transcription factors. Here, we investigated the effects of hypoxia on the activity of two ...
-
(2009)Crohn's disease (CD) and ulcerative colitis (UC) belong to the group of inflammatory bowel diseases (IBD), with complex ethiopathogenic factors that include an unbalanced immune and inflammatory response to commensal and ...
-
(2009)Background: The exposure to stressing situations may play a role in the appearance of vitiligo. Patients with the disease have a greater sensitivity to environmental stress and a lower threshold to generate catecholamine ...
-
(2009)OBJECTIVES: Laparoscopically assisted radiofrequency is a minimally invasive nephron-sparing treatment option for renal tumors, mainly in patients with high comorbidity. We present the short-term results of our series ...
-
(2009)In this stir bar sorptive extraction (SBSE) method, 16 pesticides were extracted from surface water samples by sorption onto 1 mm polydimethylsiloxane layer coated on a 10-mm-length stir bar magnet. After liquid desorption ...
-
(2009)Background: Precocious pubarche (PP), defined as the development of sexual pubic hair before 8 years of age in females and before 9 years in males, is usually a benign condition but it can also be the first sign of an ...
-
(2009)Insertional mutations in exon 4 of the ferritin light chain (FTL) gene are associated with hereditary ferritinopathy (HF) or neuroferritinopathy, an autosomal dominant neurodegenerative disease characterized by progressive ...
-
(2009)Background: Anastomotic stricture after gastric bypass for morbid obesity has been reported as the most frequent complication after surgery. The objective of this study is to determine in a prospective and consecutive ...
-
Cumulus cell apoptosis changes with exposure to spermatozoa and pathologies involved in infertility (2009)Objective: To determine whether the incidence of apoptosis in mature oocyte cumulus cells changes after insemination related to infertility. Design: Prospective study. Setting: Public hospital and university. Patient(s): ...
-
(2009)Creating and copying are two different processes; we must not confuse creativity with plagiarism. However, this distinction is problematic, because there is no possibility of creating from scratch, this implies that any ...
-
Human corpus luteum physiology and the luteal-phase dysfunction associated with ovarian stimulation (Reproductive Healthcare Ltd, 2009)The human corpus luteum is a temporary endocrine gland that develops after ovulation from the ruptured follicle during the luteal phase. It is an important contributor of steroid hormones, particularly progesterone, and ...
-
(2009)Although foraging comprises a set of behaviours that typically vary with resource availability and.or climatic conditions, few studies have analysed how foraging, particularly food hoarding, varies across populations ...
-
(2009)The brain and the nervous system are tissues with high contents of two polyunsaturated fatty acids: arachidonic acid (20:4, omega-6, AA) and docosahexaenoic acid (22:6, omega-3, DHA). Despite their abundance in these ...
-
(2009)The Vibrio parahaemolyticus 03:K6 pandemic clonal strain was first observed in southern Chile in 2004 and has since caused approximately 8,000 seafood-related diarrhea cases in this region. The massive proliferation of the ...
-
(2009)Amyloid precursor protein (APP) is a transmembrane glycoprotein widely expressed in mammalian tissues and plays a central role in Alzheimer's disease. However, its physiological function remains elusive. Cu2+ binding and ...
-
(2009)To study the variability at the myotonic dystrophy protein kinase (DMPK) gene in a Chilean sample of healthy people. DM1 is an autosomal dominant disorder caused by an expansion of a (CTG) repeat at the 3′-UTR of the gene ...
