A Rare Obstetric Outcome in Uterus Didelphys with Obstructed Hemivagina and Ipsilateral Renal Agenesis

Background: The unique clinical syndrome of uterus didelphys, obstructed hemivagina, and ipsilateral renal anomaly is very rare and can be quite difficult to recognize because of the enormous heterogeneity in its clinical presentation. There are few long-term reports of the reproductive performance of women with this syndrome following treatment, or about the location of subsequent pregnancies. Case: A case in which two spontaneous pregnancies occurred alternatively in both hemiuteri: one despite a previous ipsilateral large hematometra and hematocolpos and the other, 8 years after, simultaneously with contralateral hematometra and hematocolpos(because of vaginal restenosis), is reported. Drainage of hematocolpos was performed at 14 weeks of pregnancy with immediate pain relief. Results: Pregnancy proceeded without complications. Eight month after delivery, a vaginoplasty was performed by excising the longitudinal vaginal septum, and marsupializing the vaginal cuff. Conclusions: This case highlights the importance of a correct and early diagnosis of developmental anomalies of the urogenital tract, as well as how a conservative approach in a Mullerian anomaly with unilateral obstruction led to two successful pregnancies occurring alternatively in the unaffected and in the previously blocked side. This is additional information supporting that every effort should be made to preserve the obstructed uterus

Candida albicans Possesses Sap7 as a Pepstatin A-Insensitive Secreted Aspartic Protease

BACKGROUND: Candida albicans, a commensal organism, is a part of the normal flora of healthy individuals. However, once the host immunity is compromised, C. albicans opportunistically causes recurrent superficial or fatal systemic candidiasis. Secreted aspartic proteases (Sap), encoded by 10 types of SAP genes, have been suggested to contribute to various virulence processes. Thus, it is important to elucidate their biochemical properties for better understanding of the molecular mechanisms that how Sap isozymes damage host tissues. METHODOLOGY/PRINCIPAL FINDINGS: The SAP7 gene was cloned from C. albicans SC5314 and heterogeneously produced by Pichia pastoris. Measurement of Sap7 proteolytic activity using the FRETS-25Ala library showed that Sap7 was a pepstatin A-insensitive protease. To understand why Sap7 was insensitive to pepstatin A, alanine substitution mutants of Sap7 were constructed. We found that M242A and T467A mutants had normal proteolytic activity and sensitivity to pepstatin A. M242 and T467 were located in close proximity to the entrance to an active site, and alanine substitution at these positions widened the entrance. Our results suggest that this alteration might allow increased accessibility of pepstatin A to the active site. This inference was supported by the observation that the T467A mutant has stronger proteolytic activity than the wild type. CONCLUSIONS/SIGNIFICANCE: We found that Sap7 was a pepstatin A-insensitive protease, and that M242 and T467 restricted the accessibility of pepstatin A to the active site. This finding will lead to the development of a novel protease inhibitor beyond pepstatin A. Such a novel inhibitor will be an important research tool as well as pharmaceutical agent for patients suffering from candidiasis

Secondary crystalline phases identification in Cu2ZnSnSe4 thin films: contributions from Raman scattering and photoluminescence

In this work, we present the Raman peak positions of the quaternary pure selenide compound Cu2ZnSnSe4 (CZTSe) and related secondary phases that were grown and studied under the same conditions. A vast discussion about the position of the X-ray diffraction (XRD) reflections of these compounds is presented. It is known that by using XRD only, CZTSe can be identified but nothing can be said about the presence of some secondary phases. Thin films of CZTSe, Cu2SnSe3, ZnSe, SnSe, SnSe2, MoSe2 and a-Se were grown, which allowed their investigation by Raman spectroscopy (RS). Here we present all the Raman spectra of these phases and discuss the similarities with the spectra of CZTSe. The effective analysis depth for the common back-scattering geometry commonly used in RS measurements, as well as the laser penetration depth for photoluminescence (PL) were estimated for different wavelength values. The observed asymmetric PL band on a CZTSe film is compatible with the presence of CZTSe single-phase and is discussed in the scope of the fluctuating potentials’ model. The estimated bandgap energy is close to the values obtained from absorption measurements. In general, the phase identification of CZTSe benefits from the contributions of RS and PL along with the XRD discussion.info:eu-repo/semantics/publishedVersio

Complicações Hipertensivas na Gravidez. 1 Mês na Maternidade Dr. Alfredo da Costa

A patologia hipertensiva ocorre em 6 a 8% das gravidezes e é a segunda causa de morte materna, contribuindo com 15% para essa taxa de mortalidade. É também causa significativa de morte fetal e morbi-mortalidade neonatal. O objectivo deste trabalho foi avaliar, através de uma análise retrospectiva, as complicações hipertensivas na população de grávidas que tiveram o parto na Maternidade Dr. Alfredo da Costa (MAC) em Novembro de 2005. Durante este período 41 mulheres (10,1%) tiveram complicações hipertensivas. Treze grávidas (31,7%) tinham hipertensão crónica, dezanove (46,3%) HIG, 5 (12,2%) PE moderada e 7 (17%) PE grave, com 3 casos de síndrome HELLP. Registou-se um caso de síndrome HELLP sem hipertensão arterial. Registaram-se 9 casos de parto prematuro (22,5%) e uma morte fetal. A idade gestacional média foi 37 semanas. Assinalaram-se 9,7% de RCIU e nenhum caso de asfixia neonatal
