(Fungos microscópicos da Mata Atlântica de Paranapiacaba, São Paulo, Brasil). Na Mata Atlântica de Paranapiacaba, no estado de São Paulo, 1770 ocorrências de diferentes táxons de fungos foram registradas de julho de 1988 a maio de 1990. Para a água do riacho foram reportadas 319 ocorrências, 405 para o solo, 565 em folhas submersas de Alchornea triplinervia (Spreng.) M. Arg. e 481 em folhas dispostas sobre o solo. Mastigomycotina representou 316 ocorrências com 20 espécies, Zygomycotina 266 ocorrências com 13 espécies, Deuteromycotina 1107 ocorrências com 82 táxons e Ascomycotina 81 ocorrências com oito espécies. Os fungos foram isolados pelos métodos da lavagem de discos de folhas, placa de solo e iscagem utilizando substratos quitínicos, queratínicos e celulósicos. As folhas de A. triplinervia suportaram o maior número de táxons e de ocorrências de fungos, seguidas pelo solo e pela água do riacho.

Hormone replacement therapy (HRT) reduces cardiovascular risks, although the initiation of therapy may be associated with transient adverse ischemic and thrombotic events. Antibodies against heat shock protein (Hsp) and oxidized low density lipoprotein (LDL) have been found in atherosclerotic lesions and plasma of patients with coronary artery disease and may play an important role in the pathogenesis of atherosclerosis. The aim of the present study was to assess the effects of HRT on the immune response by measuring plasma levels of antibodies against Hsp 65 and LDL with a low and high degree of copper-mediated oxidative modification of 20 postmenopausal women before and 90 days after receiving orally 0.625 mg equine conjugate estrogen plus 2.5 mg medroxyprogesterone acetate per day. HRT significantly increased antibodies against Hsp 65 (0.316 ± 0.03 vs 0.558 ± 0.11) and against LDL with a low degree of oxidative modification (0.100 ± 0.01 vs 0.217 ± 0.02) (P<0.05 and P<0.001, respectively, ANOVA). The hormone-mediated immune response may trigger an inflammatory response within the vessel wall and potentially increase plaque burden. Whether or not this immune response is temporary or sustained and deleterious requires further investigation.

Premenstrual syndrome and premenstrual dysphoric disorder (PMDD) seem to form a severity continuum with no clear-cut boundary. However, since the American Psychiatric Association proposed the research criteria for PMDD in 1994, there has been no agreement about the symptomatic constellation that constitutes this syndrome. The objective of the present study was to establish the core latent structure of PMDD symptoms in a non-clinical sample. Data concerning PMDD symptoms were obtained from 632 regularly menstruating college students (mean age 24.4 years, SD 5.9, range 17 to 49). For the first random half (N = 316), we performed principal component analysis (PCA) and for the remaining half (N = 316), we tested three theory-derived competing models of PMDD by confirmatory factor analysis. PCA allowed us to extract two correlated factors, i.e., dysphoric-somatic and behavioral-impairment factors. The two-dimensional latent model derived from PCA showed the best overall fit among three models tested by confirmatory factor analysis (c²53 = 64.39, P = 0.13; goodness-of-fit indices = 0.96; adjusted goodness-of-fit indices = 0.95; root mean square residual = 0.05; root mean square error of approximation = 0.03; 90%CI = 0.00 to 0.05; Akaike's information criterion = -41.61). The items "out of control" and "physical symptoms" loaded conspicuously on the first factor and "interpersonal impairment" loaded higher on the second factor. The construct validity for PMDD was accounted for by two highly correlated dimensions. These results support the argument for focusing on the core psychopathological dimension of PMDD in future studies.

Diabetic retinopathy (DR) is a serious complication of diabetes mellitus that may result in blindness. We evaluated the effects of activation of endogenous angiotensin converting enzyme (ACE) 2 on the early stages of DR. Rats were administered an intravenous injection of streptozotocin to induce hyperglycemia. The ACE2 activator 1-[[2-(dimethylamino) ethyl] amino]-4-(hydroxymethyl)-7-[[(4-methylphenyl) sulfonyl] oxy]-9H-xanthone 9 (XNT) was administered by daily gavage. The death of retinal ganglion cells (RGC) was evaluated in histological sections, and retinal ACE2, caspase-3, and vascular endothelial growth factor (VEGF) expressions were analyzed by immunohistochemistry. XNT treatment increased ACE2 expression in retinas of hyperglycemic (HG) rats (control: 13.81±2.71 area%; HG: 14.29±4.30 area%; HG+XNT: 26.87±1.86 area%; P<0.05). Importantly, ACE2 activation significantly increased the RCG number in comparison with HG animals (control: 553.5±14.29; HG: 530.8±10.3 cells; HG+XNT: 575.3±16.5 cells; P<0.05). This effect was accompanied by a reduction in the expression of caspase-3 in RGC of the HG+XNT group when compared with untreated HG rats (control: 18.74±1.59; HG: 38.39±3.39 area%; HG+XNT: 27.83±2.80 area%; P<0.05). Treatment with XNT did not alter the VEGF expression in HG animals (P>0.05). Altogether, these findings indicate that activation of ACE2 reduced the death of retinal ganglion cells by apoptosis in HG rats.

Naantalissa, Rymättylän ja Merimaskun alueella tehtiin kesällä ja syksyllä 2015 maatalousalueiden kosteikkojen, suojavyöhykkeiden ja luonnon monimuotoisuuskohteiden sekä ranta-alueiden monikäytön yleissuunnitelma. Ranta-alueiden suunnittelussa tarkastellaan ranta-alueiden monikäyttöä ja arvioidaan erityisesti ruovikoihin liittyviä toimenpiteitä. Suunnittelun tavoitteena oli löytää potentiaalisia rantaniittyjä ja ruovikoita hoi-don piiriin. Maatalousalueiden yleissuunnittelussa tuodaan näkyväksi alueet, joilla luonnon monimuotoisuutta tai vesien tilaa voidaan kohentaa. Suunnitelmassa on selvitetty alueen suojavyöhyketarpeet, esitetty maata-louskosteikkojen perustamispaikkoja sekä tuotu esille luonnon ja maiseman monimuotoisuuskohteita sekä perinnebiotooppeja. Ranta-alueiden monikäytön yleissuunnittelun kohteena olivat ranta-alueet Rymättylän pohjoisosassa ja Merimaskun länsiosan alueella. Maatalousalueiden kosteikkojen, suojavyöhykkeiden ja luonnon monimuotoisuus-kohteiden yleissuunnittelu kattaa Rymättylän pohjoisosan lisäksi Airismaan sekä Aaslaluodon. Monimuotoisuusalueiden, kosteikkojen ja suojavyöhykkeiden kartoitukset pohjautuivat ProAgria Suomen Talousseuran aikaisempiin tarvekartoitushavaintoihin, joita tehtiin hankkeen Tasapainoa luontoon aikana vuosina 2010–2014. Kartoituksen yhteydessä tarkasteltiin myös Turun AMK:n Niukonlahden vesiensuojeluohjelmaa 2013. Suunnitelmalla pyritään auttamaan viljelijää hyödyntämään maatalouden ympäristökorvausjärjestelmää. Kohteiden maininta suunnitelmassa ei sido eikä velvoita maanomistajaa toimenpiteisiin vaan yleissuunnitelman tietoja voidaan hyödyntää kohteiden kunnostusta ja hoitoa suunniteltaessa.
