A catalog of the types of Stratiomyidae, Tabanidae, Asilidae sensu lato, and Syrphidae (Insecta, Diptera) deposited in the Museo Argentino de Ciencias Naturales, Buenos Aires (MACN) With an appendix on types of Tabanidae deposited in the Instituto "Dr. Carlos G. Malbrán", Buenos Aires (ANLIS)

The type specimens of all accepted categories of three names of Stratiomyidae, fifty-nine of Tabanidae, twenty-four of Asilidae sensu lato (includes Leptogastridae), and twenty of Syrphidae are recorded. In an appendix twelve paratypes of six species of Tabanidae are recorded, housed in the Administración Nacional de Laboratorios e Institutos de Salud "Dr. Carlos G. Malbrán" (ANLIS), Departamento Vectores, Buenos Aires.Fil:Bachmann, A.O. Universidad de Buenos Aires. Facultad de Ciencias Exactas y Naturales; Argentina

A catalog of the types of craneflies (Limoniidae and Tipulidae) (Insecta, Diptera) deposited in the Museo Argentino de Ciencas Naturales, Buenos Aires

The type specimens of all accepted categories of twenty-eight names of craneflies (twenty-two of Limoniidae and six of Tipulidae), housed in this Museum are recorded. Specimens labeled as types, but which are not types, or are only very dubiously acceptable as types, are recorded in a separate list, in order to assist in future research. Most of the species here catalogued were described by Dr. C.P. Alexander, based upon specimens from this Museum, sent to him by C. Bruch.Fil:Bachmann, A.O. Universidad de Buenos Aires.

A catalog of the types of Mycetophilidae (Insecta, Diptera) deposited in the Museo Argentino de Ciencias Naturales, Buenos Aires

The types (only paratypes) of 102 species of Mycetophilidae described and deposited in this Museum by Dr. José Pedro Duret are recorded. A selection from his rich collection was also here deposited by him. Most of his collection was acquired by Dr. Loic Matile, Paris, France. The Museum houses no other types of species of this family.Fil:Bachmann, A.O. Universidad de Buenos Aires. Facultad de Ciencias Exactas y Naturales; Argentina

Mitigating skin tone bias in linear array in vivo photoacoustic imaging with short-lag spatial coherence beamforming

Photoacoustic (PA) imaging has the potential to deliver non-invasive diagnostic information. However, skin tone differences bias PA target visualization, as the elevated optical absorption of melanated skin decreases optical fluence within the imaging plane and increases the presence of acoustic clutter. This paper demonstrates that short-lag spatial coherence (SLSC) beamforming mitigates this bias. PA data from the forearm of 18 volunteers were acquired with 750-, 810-, and 870-nm wavelengths. Skin tones ranging from light to dark were objectively quantified using the individual typology angle (ITA°). The signal-to-noise ratio (SNR) of the radial artery (RA) and surrounding clutter were measured. Clutter was minimal (e.g., −16 dB relative to the RA) with lighter skin tones and increased to −8 dB with darker tones, which compromised RA visualization in conventional PA images. SLSC beamforming achieved a median SNR improvement of 3.8 dB, resulting in better RA visualization for all skin tones

Ospemifene, a non-oestrogen selective oestrogen receptor modulator for the treatment of vaginal dryness associated with postmenopausal vulvar and vaginal atrophy: A randomised, placebo-controlled, phase III trial

a b s t r a c t Objective: To evaluate the efficacy and safety of ospemifene, a novel selective oestrogen receptor modu- lator, in the treatment of vaginal dryness in postmenopausal women with vulvovaginal atrophy (VVA). Study design: A 12 week, multicentre, randomised, double-blind, parallel-group phase III study of women (40-80 years) with VVA and self-reported vaginal dryness as their most bothersome symptom. Main outcome measures: The co-primary efficacy endpoints were the change from baseline to Week 12 in (1) percentage of parabasal cells in the maturation index (MI), (2) percentage of superficial cells in the MI, (3) vaginal pH, and (4) severity of vaginal dryness. Safety assessments included physical examination, cervical Papanicolaou test and clinical laboratory analyses. Endometrial thickness and histology was also assessed. Results: A total of 314 women were randomised to once-daily ospemifene 60 mg/day (n = 160) or placebo (n = 154). Significant improvements in the percentages of parabasal and superficial cells in the MI and vaginal pH were observed with ospemifene compared with placebo (p < 0.001 for all parameters). The mean change from baseline in severity score of vaginal dryness reported by women receiving ospemifene compared with those receiving placebo approached statistical significance (p = 0.080). Improvements in each of the four co-primary endpoints with ospemifene were statistically significant compared to placebo in the per protocol population. The majority of treatment-emergent adverse events were considered mild to moderate in severity. Conclusions: Once-daily oral ospemifene 60 mg was effective for the treatment of VVA in postmenopausal women with vaginal dryness. © 2014 The Authors. Published by Elsevier Ireland Ltd.

Stonefly (Plecoptera) fauna in a mountainous area of Central Brazil: composition and adult phenology

A survey of the stonefly (Plecoptera) fauna of streams of the Almas River basin, Pirenópolis, Goiás State, Central Brazil, is presented as well as data of some factors that could affeet the temporal distribution of the adults. For checking adult phenology, light sources were used in three stations from June 1993 to Jully 1994. The sampled individuais were identified to species or morphospecies, as possible. In this study, 301 individuais belonging to the perlid genera Anacroneuria Klapálek, 1909, Kempnyia Klapálek, 1916 and Macrogynoplax Enderlein, 1909 were collected. Adults of most species were collected along the studied period, except for those of Kempnyia that were restricted to the warm-rainy season, the same pattern for this genus in southeastern Brazil. Although adults of most species were collected along most of the studied period, the largest number of adults was collected in the months with larger mean temperatures, showing a clear seasonality in abundance
