2. ARMC5 mutations are associated with high levels of proliferating cell nuclear antigen and the presence of the serotonin receptor 5HT4R in PMAH nodules
ABSTRACT Objective To analyze the morphological and functional characteristics of primary macronodular adrenal hyperplasia (PMAH) nodules carrying or not carrying ARMC5 mutations and the consequences of the presence of mutations in terms of the pattern of macronodule composition and functional state. Subjects and methods The analyses were performed by he

3. Anatomical study of the pigs temporal bone by microdissection
PURPOSE: Initial study of the pig`s temporal bone anatomy in order to enable a new experimental model in ear surgery. METHODS: Dissection of five temporal bones of Sus scrofa pigs obtained from UNIFESP - Surgical Skills Laboratory, removed with hole saw to avoid any injury and stored in formaldehyde 10% for better conservation. The microdissection in all fi

5. Microdissection Testicular Sperm Extraction (micro-TESE) as a Sperm Acquisition Method for Men with Nonobstructive Azoospermia Seeking Fertility: Operative and Laboratory Aspects
Introduction Rare foci of sperm production may be found in up to 60% of men with nonobstructive azoospermia (NOA). Sperm production, if present, is minimal for sperm appearance in the ejaculate. Given that there are no treatment options to restore fertility, sperm retrieval is the only alternative to find testicular sperm than then can be used for in vitro

6. Hypogonadotropic Hypogonadism Revisited
Impaired testicular function, i.e., hypogonadism, can result from a primary testicular disorder (hypergonadotropic) or occur secondary to hypothalamic-pituitary dysfunction (hypogonadotropic). Hypogonadotropic hypogonadism can be congenital or acquired. Congenital hypogonadotropic hypogonadism is divided into anosmic hypogonadotropic hypogonadism (Kallmann s

8. IL-2, IL-5, TNF-α and IFN-γ mRNA expression in epidermal keratinocytes of systemic lupus erythematosus skin lesions
OBJECTIVE: To analyze cytokine gene expression in keratinocytes from patients with systemic lupus erythematosus (SLE). INTRODUCTION: Keratinocytes represent 95% of epidermal cells and can secrete several cytokines. METHODS: Keratinocytes were obtained by laser microdissection from 21 patients with SLE (10 discoid and 11 acute lesions) at involved and uninvol

9. Estudo comparativo da composição das partículas ambientais depositadas e retidas nos pulmões e linfonodos hilares pulmonares / Comparative study of the composition of the ambient particles deposited and retained in the lungs and hylar lymph nodes
RATIONALE: Prolonged exposure to ambient particles is associated with premature mortality due to cardio respiratory diseases and lung cancer. Size and composition of these particles determine toxicity, aggravated by their long term retention in the lungs. In this context, it is plausible to postulate that different particles with different elemental composit

10. Use of chromosome microdissection in fish molecular cytogenetics
Chromosome microdissection is a technique in which whole chromosomes or chromosomal segments are dissected under an inverted microscope yielding chromosome-specific sequences. Several protocol modifications introduced during the past 15 years reduced the number of chromosomes required for most applications. This is of particular interest to fish molecular cy

11. Chromosome evolution: Karyotype variability in Platyrrhini and studies of sinteny and homologies between human chromosomes / Evolução cromossômica: estudo da variabilidade cariotípica em Platyrrhini e das homeologias e sintenias com cromossomos humanos
We studied the karyotypes of Brazilian monkeys (Platyrrhini, Primates) using both traditional cytogenetic techniques as well as FISH. FISH analysis employed human probes for chromosome 14, 15 and the X chromosome and a probe of the Y chromosome of Brachyteles arachnoides obtained by chromosome microdissection. Twenty-four individuals of Alouatta guariba clam

12. Evolução de cromossomos sexuais em Eigenmannia virescens (Teleostei: Gymnotiformes) / Evolution of sex chromosomes in the genus Eigenmannia (Teleostei: Gymnotiformes)
Cromossomos sexuais evoluíram repetidas vezes independentemente nos grandes grupos de vertebrados. Sistemas sexuais altamente diferenciados e antigos são caracterizados por grandes diferenças morfológicas e de conteúdo gênico entre os dois cromossomos homólogos onde a recombinação é restrita a uma pequena região homóloga. Os sistemas recentes car
