Validation of a reaction volume reduction protocol for analysis of Y chromosome haplotypes targeting DNA databases
The use of Y chromosome haplotypes, important for the detection of sexual crimes in forensics, has gained prominence with the use of databases that incorporate these genetic profiles in their system. Here, we optimized and validated an amplification protocol for Y chromosome profile retrieval in reference samples using lesser materials than those in commercial kits... Read More»

FYB polymorphisms in Brazilian patients with type I diabetes mellitus and autoimmune polyglandular syndrome type III
The present study investigates the effects of electroacupuncture (EA) on urinary bladder pressure (UBP) in patients with acute gastrointestinal injury (AGI). Twenty patients with AGI admitted to the First Hospital of Jiaxing intensive care unit from December 2011 to June 2013 were evaluated. Conventional group patients (n = 10) were administered moderate enteral nutritional support, and electro.. Read More»

Association of TNF-�?±, CTLA4, and PTPN22 polymorphisms with type 1 diabetes and other autoimmune diseases in Brazil
Type 1 diabetes mellitus (T1D) is a complex disorder characterized by an autoimmune response against human pancreatic beta-cells. Patients with T1D can also develop a response toward one or more other factors, such as in autoimmune thyroiditis (AITD) and celiac disease (CD). In the presence of T1D + AITD, the patient is diagnosed with autoimmune polyglandular syndrome type III (APSIII); patient.. Read More»

HLA-B35, a common genetic trait, in a familial case of Henoch-Schoenlein purpura and Berger��?s disease
Nephritis characterized by IgA mesangial depositions has been described both in Henoch-Schoenlein purpura (HSP) and in Berger’s disease (BD), but common genetic traits are still uncertain. We report here the case of two brothers, the first affected by HSP with persistent nephritis and the second by BD, accidentally discovered as silent microhematuria 1 year af.. Read More»

Analysis of the beta-globin gene in DNA of suspected thalassemic great apes
DNA was recovered from teeth of 2 great ape skeletons, Pan troglodytes (Ptr) and Pongo pygmaeus (Ppy), belonging to a 19th-century zoological collection. The skeletons presented morphological alterations possibly associated with β-thalassemia: Ptr had deformation of the calvaria and oro-maxillo-facial bones with porotic hyperostosis and extended osteoporotic lesions of the skeleton,..

Frequency of human papillomavirus types 16, 18, 31, and 33 and sites of cervical lesions in gynecological patients from Recife, Brazil
Human papilloma virus (HPV) is a well-established cause of cervical cancer. While many studies have been performed so far on HPV viral biology, mode of infection and prevention measures, scanty information is available on lesion sites of infected women and the incidence of viral types at specific locations. We looked for a possible relationship between the most comm.. Read More»

Human autosomal DNA and X chromosome STR profiles obtained from Chrysomya albiceps (Diptera: Calliphoridae) larvae used as a biological trace
The use of insects to answer questions in criminal investigations, as well as a combination of forensic genetic techniques to obtain human DNA from the organisms, especially necrophagous dipterians, have gained ground in recent decades among researchers and professionals in this area. The objective of our study was to evaluate and compare two methods of human DNA ex.. Read More»

HLA-G genetic variants and hepatocellular carcinoma: a meta-analysis
Human leukocyte antigen (HLA)-G is a key tolerogenic molecule mainly expressed in the placenta and is crucial for implantation of the embryo and immunological tolerance of the fetus during pregnancy. However, under pathological conditions, such as cancer or viral infections, HLA-G can be expressed in other tissues. The gene coding for HLA-G (HLA-G, chromosome 6p21.3) presents numerous polymorph..

Detecting multiple DNA human profile from a mosquito blood meal
Criminal traces commonly found at crime scenes may present mixtures from two or more individuals. The scene of the crime is important for the collection of various types of traces in order to find the perpetrator of the crime. Thus, we propose that hematophagous mosquitoes found at crime scenes can be used to perform genetic testing of human blood and aid in suspect investigation. The aim ofthe.. Read More»

Association of interferon-induced helicase C domain (IFIH1) gene polymorphisms with systemic lupus erythematosus and a relevant updated meta-analysis
Systemic lupus erythematosus (SLE) is a complex autoimmune disorder presenting heterogeneous clinical manifestations. A number of genes involved in SLE susceptibility are related to the type I interferon (IFN) pathway. IFN mediates innate immune responses and its increased levels contribute to the breakdown of peripheral tolerance. Interferon-induced helicase C doma.. Read More»
