Median Portion Research Articles

Calliostomatidae, Colloniidae, Margaritidae, and Solariellidae (Gastropoda: Trochoidea) collected by the Marion Dufresne (MD55) expedition in southeastern Brazil, with description of a new species of Calliostoma.

The deep-water mollusks collected during the Marion Dufresne (MD55) expedition to the southeastern Brazilian coast in 1987 have been studied in several recent works. The present paper lists and diagnoses 19 species belonging to the vetigastropod families Calliostomatidae, Colloniidae, Margaritidae, and Solariellidae. A new species, Calliostoma valkuri sp. nov., is described. It is mainly characterized by a very short teleoconch I, with limits marked by conspicuous varices and sculpture consisting of 3 spiral threads; sculpture of the teleoconch II consisting of spiral cords with thorn-like projections; and the presence of two strongly marked cords on the median portion of the whorls. Based on the MD55 samples and complementary specimens from other expeditions, the following species have their geographical and/or bathymetrical range extended: Bathymophila euspira, Calliostoma gemmosum, Calliostoma rude, Callogaza watsoni, Gaza compta, Falsimargarita terespira, Homalopoma boffii, Lamellitrochus cancapae comb. nov., Lamellitrochus pourtalesi, Margarites imperialis, and Solariella quinni.

A new kannemeyeriiform dicynodont (Ufudocyclops mukanelai, gen. et sp. nov.) from Subzone C of the Cynognathus Assemblage Zone, Triassic of South Africa, with implications for biostratigraphic correlation with other African Triassic faunas

ABSTRACTA new taxon of kannemeyeriiform dicynodont, Ufudocyclops mukanelai, is described based on a well-preserved skull from Subzone C of the Cynognathus Assemblage Zone, which are the youngest strata (probably Middle Triassic) of the Beaufort Group (uppermost Burgersdorp Formation) in South Africa. Ufudocyclops mukanelai is diagnosed by its autapomorphic intertemporal morphology: the intertemporal bar in this taxon is ‘X’-shaped—broad anteriorly and posteriorly but distinctly ‘pinched’ at mid-length and bears a deep, triangular depression immediately behind the enormous pineal foramen. The new kannemeyeriiform can also be diagnosed by the presence of a laterally expanded jugal plate beneath the orbit, and highly discrete, ovoid nasal bosses separated by a broad, unornamented median portion of the premaxilla and the nasals. Two partial dicynodont skulls from this subzone, previously identified as specimens of the otherwise Tanzanian taxon Angonisaurus, are also referable to U. mukanelai. Removal of these specimens from the hypodigm of Angonisaurus eliminates a crucial point of correlation between Cynognathus Subzone C and the Manda Beds of Tanzania and suggests that Subzone C preserves a distinct, endemic fauna, not just a southern extension of the better-known Middle–Late Triassic tetrapod faunas from Tanzania and Zambia. Inclusion of Ufudocyclops in a phylogenetic analysis of anomodonts recovers it as an early stahleckeriid, the first record of this clade from the Cynognathus Assemblage Zone.

Brain mapping of the gonadotropin-inhibitory hormone-related peptide 2 with a novel antibody suggests a connection with emotional reactivity in the Japanese quail (Coturnix japonica, Temminck & Schlegel, 1849).

Gonadotropin-inhibitory hormone (GnIH) is a neuropeptide first discovered in the quail brain that is involved in the control of reproductive physiology and behaviors, and stress response. GnIH gene encodes a second peptide, GnIH-related peptide-2 (RP2), the distribution and function of which remain unknown. We therefore studied GnIH-RP2 distribution by immunohistochemistry using a novel antibody capable of discriminating between GnIH and GnIH-RP2. The overall distribution of GnIH-RP2 is similar to that of GnIH. The vast majority of labeled neurons is located in the paraventricular nucleus (PVN) of the hypothalamus. Labeling of fibers is conspicuous in the diencephalon, but present also in the mesencephalon and telencephalon. Several regions involved in the control of reproduction and stress response (the PVN, septum, bed nucleus of the stria terminalis and nucleus commissura pallii) showed a dense network of immunolabeled fibers. To investigate the potential function of GnIH-RP2 we compared its expression in two quail lines genetically selected for divergence in their emotional reactivity. A quantitative analysis in the above-mentioned brain regions showed that the density of fibers was similar in the two lines. However, the number of GnIH-RP2 labeled neurons was higher in the median portion of the PVN in birds with higher emotional reactivity. These results point to a possible involvement of GnRH-RP2 in modulating stress response and/or emotional reactivity.

Dynamics of secondary pollen presentation in Campanula medium (Campanulaceae).

After several decades of research, dynamics and patterns of mating system in floral evolution remain incompletely understood, especially with regards to strategies that combine both outcrossing and selfing, as frequently recorded in the genus Campanula. Data about temporal and spatial dynamics of secondary pollen presentation are still scarce in literature: we investigated them using Campanula medium (Campanulaceae) as case study. Experimental pollinations were conducted under natural conditions, to characterise the breeding system of this species. Effects on stigma opening and stigma receptivity of stylar pollen presence were investigated in manipulated flowers. The temporal dynamics and fitness of male and female functional phases were estimated. Flower visitors and their interactions with sexual parts of the flower were also annotated. C. medium is xenogamous and self-incompatible, with a clear temporal separation between sexual functional phases. Floral lifespan is shortened by experimental outcrossing. Removal of pollen from the style shortened the time span of male function. Pollen viability was highest at the beginning of the anthesis, decreasing during the flowering period, whereas stigmatic receptivity shows an opposite trend. We found a severe pollen limitation in the studied population. Bees were the most frequent floral visitors. In some of these insects we observed stereotyped interactions with the reproductive structures of the flower, in particular with the pollen, exposed along the upper and median portion of the style. Sexual phases in C. medium are inversely correlated and finely spatially and temporally coordinated, since stigma maturation is scalar along its length and depends on pollen presence on the style. Overall, our findings push forward the knowledge on reproductive strategies in Campanula.

Quadricoccopsis gen. nov., a new genus of Quadricoccus-like algae in Oocystaceae from China (Trebouxiophyceae, Chlorophyta)

Members of Quadricoccus-like algae are characterized by oval to ellipsoid cells adherent to the bowl-shaped or stretched, empty mother cell walls and are common in phytoplankton of inland waters. To date, the morphologically similar genera Quadricoccus and Lobocystis are accepted for this group and the former had been phylogenetic positioned in Oocystaceae. In this study, seven strains of Quadricoccus-like algae were identified and successfully cultured in the laboratory. Light and electron microscope observations and phylogenetic analysis revealed that the strains represent three different species within a new genus, described here as Quadricoccopsis gen. nov. It differed from genus Quadricoccus by characteristically cell adherent mode that two pairs of daughter cells connected to the mother cell remnant respectively by the pole and median portion and distinguished from Lobocystis by variable 2-4-8 autospores, characteristically cell adherent mode and only found in limnetic water. The three new species, described here as Q. simplex, Q. parva and Q. glomerata, differed in cell size, colony morphology and autospore number. Phylogenetic analysis revealed the genus Quadricoccopsis in Oocystaceae and a close relationship with Oocystidium, which is far away from the phylogenetic position of Quadricoccus in one of the granulated clades. The Quadricoccus-like algae were, therefore, proved to be a paraphyly. Furthermore, apart from Planctonema-like algae, the Oocystaceae characteristic cell wall ultrastructure, which is multi-layered with cellulose fibrils in each layer perpendicular to those of the adjoining layer, is not shown again in genus Quadricoccopsis. Different cell wall substructures may be related to the colony formation mechanism. Whether the ultrastructure criterion is applied to all the Oocystaceae needs to be re-evaluated and, further, the definition of this family should be discussed.

Two new species of Hanshumba from Southeastern Brazil and a key to males of the genus (Insecta: Hemiptera: Cicadellidae: Cicadellini)

The genus Hanshumba Young, 1977 is recorded from Southeastern and Southern Brazil (Atlantic Forest) and currently includes only three species. Here we describe and illustrate, based mainly on features of the male terminalia, two new species from State of Espírito Santo, Municipality of Santa Teresa: H. setifera sp. nov. and H. teresa sp. nov. The former can be distinguished by the male pygofer and anal tube with large processes bearing numerous setae and the aedeagus with pair of dentiform processes on median portion, whereas the latter has three pairs of longitudinal flanges on the aedeagal shaft. A key to males of the genus is added and its taxonomic status is briefly discussed.

P37. Various sonographic gray-scale measures of the peripheral nerve differ between ALS and ALS disease mimics

Background We aimed to examine whether distinct sonographic gray-scale measures of the peripheral nerve vary between amyotrophic lateral sclerosis (ALS), ALS disease mimics and various neuropathies to ascertain the diagnostic value of high-resolution ultrasound for the differentiation of these disorders. Methods Our analysis comprised n = 54 controls and n = 250 patients (ALS n = 169, hereditary spastic paraplegia [HSP] n = 25 [pure and complex], primary lateral sclerosis [PLS] n = 13, immune-mediated neuropathies [IMNs] n = 12, hereditary demyelinating neuropathies [HDNs] n = 13, hereditary axonal/mixed neuropathies [HMNs] n = 13, hereditary neuropathy with liability to pressure palsy [HNPP] n = 5). Peripheral nerve ultrasound was conducted and offline analysis of median and ulnar nerve segments, each considered as a region of interest (ROI), comprised the calculation of the nerves’ cross sectional area (CSA), median echo intensity (EI), echo variance (EV), fascicular portion (hypoechoic fraction [HF]) and textural correlation (TCOR). As there were no side differences, left- and right-sided measures were averaged. General linear models were conducted to assess group effects on various sonographic measures (significant at p Results Sonographic measures depended on age, sex, height and weight. At entrapment and non-entrapment sites IMNs and HDNs revealed nerve enlargement compared to the remainder, while in HDNs compared to IMNs nerve CSA was even greater (2fold vs. 3fold enlargement compared to controls). In hereditary neuropathies (HDNs, HMNs) median nerve EI was lowest, which was accompanied by high EV, fascicular enlargement (high HF) and alterations of the nerves’ texture (TCOR). In ALS (all subtypes) versus the remainder comprising HSP, PLS and IMNs, ulnar nerve CSA was smaller; moreover, in ALS compared to HSP or axonal/mixed neuropathies (HMNs) the median nerves’ texture pattern (TCOR) was different. In HNPP compared to the remaining groups (except IMNs and HDNs) wrist median nerve CSA (entrapment site) was greater, which was related to fascicular enlargement (high HF). Results remained unchanged after model adjustment for age, sex, height and weight. Conclusion ALS, ALS disease mimics and various neuropathies are not only characterized by distinct sonographic nerve areas, but also reveal in-between-group differences of further sonographic gray-scale nerve measures. Future studies need to address the question how sonographic composite scores could aid in the differentiation between ALS and its disease mimics and how those scores relate to further ultrasound features such as the nerves’ microvascular blood flow.

Parental Reports of Lunch-Packing Behaviours Lack Accuracy: Reported Barriers and Facilitators to Packing School Lunches.

Parents influence the foods their children consume and often provide proxy reports of this intake. One way parents exert this influence is by providing home-packed lunches. This study compared parental reports of foods packed in children's lunches with what was actually packed and identified parental barriers and facilitators to packing lunches. Grade 3 and 4 student-parent dyads (n = 321) in 19 elementary schools in Ontario participated. Parental reports and actual packed lunch contents were collected via self-administered surveys and direct observation, respectively. Parental barriers and facilitators were obtained through open and closed survey questions. Median portions packed were significantly higher for sugar-sweetened beverages and snacks and significantly lower for fruits, fruit juice, vegetables, milk/alternatives, and meat/alternatives than parents reported. Packing a healthy lunch was "important/very important/of the utmost importance" for 95.9% of respondents, and 97.5% perceived their nutrition knowledge as "adequate/good/very good". Barriers to packing a lunch included: child's food preferences, time, finances, allergy policies, and food safety. Nutrition resources, observing other children's lunches, child's input, and planning ahead were identified as facilitators. Strategies to improve packed lunches should move beyond parental nutrition knowledge and importance of lunch packing to address parental barriers and facilitators.

Two new species of Odontostilbe historically hidden under O. microcephala (Characiformes: Cheirodontinae)

ABSTRACT Specimens historically identified as Odontostilbe microcephala from the upper rio Paraná and Andean piedmont tributaries of the río Paraguay are reviewed and split in three species. We found that the distribution of O. microcephala is restricted to the Andean slope of the río Paraguay basin. The species is distinguished from congeners with subterminal mouth by the elongate body, usually 10-12 gill rakers on upper branch and smaller horizontal orbital diameter (24.6-32.8 % HL, mean 28.7%). Specimens from upper rio Paraná constitute two new species, diagnosed from other Cheirodontinae by the presence of mesopterygoid teeth, grouped on median portion and forming a continuous row. The new species are distinguished from each other by having premaxillary teeth with five cusps vs. nine cusps and by the number of lamellae in left and right sides of central median raphe of olfactory rosette with 20-21 vs. 11-12.

Web blight (Thanatephorus cucumeris): a new disease on leaves of okra plants

ABSTRACT: In an experiment on organic production of okra (Abelmoschus esculentus (L.) Moench) that was carried out from September 2013 to January 2014, in Manaus, Amazonas state, Brazil, we observed large chlorotic, necrotic, helical, discontinuous, dark or light-brown lesions with partial detachment of the injured area on the adaxial surface of leaves located in the median and basal portions of the plants. A whitish mycelium mantle covers the lesions on the leaves at the abaxial surface at high moisture conditions. Using morphological characteristics, Koch’s postulates, and phylogenetic analyses of the ITS-5.8S rDNA region, we identified that the fungus causing the lesions on the okra leaves was Thanatephorus cucumeris (Frank) Donk (asexual stage of Rhizoctonia solani Kuhn of the anastomosis group AG-1 ID). This is the first report of T. cucumeris causing web blight on okra in Brazil, and probably in the world. So far, T. cucumeris was described on okra only on post-harvest pods rotting and seedlings’ damping off.

Morphometric Study of the Lumbar Posterior Longitudinal Ligament.

ObjectiveMorphometric data for the lumbar posterior longitudinal ligament (PLL) was investigated to identify whether there is a difference in the morphometry of the PLL of the lumbar spine at each level with respect to the pattern of intervertebral disc displacement.MethodsIn 14 formalin-fixed adult cadavers (12 males and 2 females), from L1 to L5, the authors measured the width and height of the PLL and compared them with other landmarks such as the disc and the pedicle.ResultsHorizontally, at the upper margin of the disc, the central portion of the superficial PLL covered 17.8–36.9% of the disc width and the fan-like portion of the PLL covered 63.9–76.7% of the disc width. At the level of the median portion of the disc, the PLL covered 69.1–74.5% of the disc width. Vertically, at the level of the medial margin of the pedicle, the fan-like portion of the PLL covered 23.5–29.9% of the disc height. In general, a significant difference in length was not found in the right-left and male-female comparisons.ConclusionThis study presents the morphometric data on the pattern of intervertebral disc displacement and helps to improve the knowledge of the surgical anatomy of the lumbar PLL.

Investigation on rooting ability of twenty olive cultivars from Southern Italy

The effects of two different types of auxins (660 ppm alpha-naph-thaleneacetic acid - NAA - in liquid solution or 750 ppm alpha-naphthaleneac- etamide - NAD - dispersed in a talcum powder) and cuttings from three differ- ent portions of the shoots (basal, middle and apical) on the rooting ability of twenty autochthonous olive cultivars were investigated in two growing seasons (spring and autumn). The results showed that the autochthonous olive cultivars of the Campania Region are characterized by a wide variability in the potential rhizogenic ability. The two periods of cutting collection (March and September) significantly affected the rooting aptitude of the cultivars, indicating that in some cultivars the cuttings collected in autumn had a higher rooting rate than those collected in spring. The effects of NAA and NAD on rooting strongly depended on interaction with the cultivar, time of collection (autumn or spring) and type of cuttings (basal, medium or apical). Among the twenty cultivars tested, we found only eight cultivars with a satisfactory rooting ability after hor- monal applications (Ortolana, Racioppella, Tenacella, Tonda, Biancolilla, Carpellese, Cornia and Pisciottana). In general, the apical and the median portions of the shoots gave the best rooting results.

Changes in Typical Portion Sizes of Commonly Consumed Discretionary Foods among Australian Adults from 1995 to 2011-2012.

This study aimed to examine the changes in typical portion sizes of commonly consumed discretionary foods among Australian adults from 1995 to 2011–2012. Data of adults (age ≥19 years) from the 1995 Australian National Nutrition Survey and 2011–2012 National Nutrition and Physical Activity Survey were used. Typical portion sizes (median portion) of fourteen discretionary foods that contributed the most to energy intake were determined. Ten out of fourteen food categories demonstrated a significant change in kJ per typical portion from 1995 to 2011–2012 (p ≤ 0.001). kJ per typical portion increased for pizza, cake, sausage, cereal bar, processed meat, ice cream and wine, with pizza and cake demonstrating the largest increases (+570 kJ and +950 kJ in 2011–2012, respectively; both +66% above 1995). In contrast, kJ per typical portion of pastry, snack food and potato fries decreased by 10–40% over time, and did not change for biscuit, chocolate, sugar-sweetened beverage and beer. Similar changes were observed for grams per typical portion consumed. Temporal trends in typical portion sizes were similar according to age group, gender and socioeconomic status. The findings suggest that population-wide strategies that enable consumers to choose smaller portions of discretionary foods are needed to reduce the excess consumption of these products.

Descriptions of eight new Acrogonia species from the Amazon region, including peculiar features of the female genitalia (Hemiptera: Cicadellidae: Cicadellinae: Proconiini).

Eight new species of the agriculturally important sharpshooter genus Acrogonia Stål, 1869 are described and illustrated from Brazil (one of them also recorded from Peru): A. amazonensis sp. nov. (state of Amazonas), A. clarae sp. nov. (states of Amazonas and Amapá), A. barbara sp. nov. (state of Mato Grosso), A. youngi sp. nov. (department of Madre de Dios in Peru and state of Acre), A. albertoi sp. nov. (state of Pará), A. tenuis sp. nov. (state of Mato Grosso), A. filiformis sp. nov. (states of Pará and Mato Grosso), and A. interrupta sp. nov. (state of Mato Grosso). In addition to the external morphology, color pattern and male genitalia, this paper includes detailed descriptions and illustrations of the female genitalia of three new species (A. barbara, A. filiformis and A. tenuis). The first ovipositor valvulae of A. tenuis are quite peculiar because they bear a large basal lobe and a projection on the median portion of the ventral margin, both displaying setae. Females of the other five new species are not known.

Osmophore diversity in the Catasetum cristatum Lindl. alliance (Orchidaceae: Catasetinae)

Catasetum is a neotropical orchid genus of 130 species characterized by its unisexual flowers. They are pollinated by male Euglossini bees. It is widely know that these bees collect volatile compounds in Catasetum from structures called osmophores. However, there is little information on morpho-anatomy and histochemistry of secretory tissues for this neotropical genus and data are lacking. Based on these arguments members of the Catasetum cristatum alliance, namely C. arietinum, C. ariquemense, C. barbatum, C. carolinianum, C. cristatum, C. lanciferum, C. multifidum, C. multifissum, C. rivularium and C. semicirculatum were analyzed. The labellum of male flowers of this alliance is elongate and with fimbriate margins, possessing two protuberances and a median saccate portion. The labellum of female flowers is galeiform and there is no ornamentation. The entire adaxial surface of the labellum is secretory in both sexes, including the fimbriae of male flowers. The structure of the secretory tissue is similar among species, and they are composed of a simple epidermis and five layers of underlying parenchyma. In most species the epidermis is flat, and cells are elongated in the saccate portion. In C. ariquemense and C. carolinianum the epidermal cells are papilous, while in C. semicirculatum they have convex surface (male flowers). The histochemical analysis detected lipophilic droplets and starch grains inside the secretory cells. All characteristics observed are encountered in secretory tissues with high-energy demand, as is common in osmophores.

ANATOMICAL AND CHEMICAL INVESTIGATIONS ON ASPARAGUS OFFICINALIS L. (ASPARAGACEAE)

Although Asparagus (Asparagus officinalis L.) is chiefly known as a vegetable herb, little information about the botanical characteristics of such plant are available. Therefore, it is aimed in this study to bring light more information about the morphological, anatomical and some important chemical contents of vegetative and reproductive organs of the plant, throughout the consecutive stages of its entire life span under the local conditions. Seeds of Asparagus (cv. Mary Washington 500 W) were sown 2nd Feb. 2013. The field experiment was carried out at the Experimental and Research Station of Fac. of Agric., Cairo Univ., Giza, Egypt during the two successive growing seasons 2013 and 2014. Asparagus is a herbaceous, perennial plant that grows up to 1.5- 2 m height. The plant posses aerial stems (ferns) and much- branched feathery foliage. The leaves are triangular scales like, 3-7 mm in length. The cladodes (modified stems) arise in the axis of scale leaves . Cladodes are found in fascicles (3-6) on each node. The flowers are bell- shaped, greenish –white to yellowish, 4.5-6.5mm long, with 6- tepals,single or in clusters of 2-3. Anatomical studies were carried out for various organs of Asparagus plant including, apex of the aerial stem, visible internode below shoot apex, median portion of the aerial stem, the cladode , median portion of spear, scale - like leaf, rhizome, adventitious root. The major chemical metabolites contents of spear were determined.

Descriptions of a new species and the gyne in the rarely collected arboreal genera Paratopula and Rotastruma (Hymenopytera: Formicidae) from Hong Kong, with a discussion on their ecology

Despite its relatively large size among the Myrmicinae of the Indomalayan region, collection events of Paratopula Wheeler are rare. Here we discuss the discovery of Paratopula in Hong Kong and present Paratopula bauhinia sp. nov as a new species. This addition brings the number of globally described species for the genus to twelve species, four of which are known only from the reproductive caste. Paratopula bauhinia sp. nov . can be distinguished from previously described species by the combination of the following features: 10 teeth on the masticatory margin of mandibles, apically acute hairs, a rounded median portion of the anterior margin of the pronotum, postpetiole broader than long, and straight, blunt propodeal spines. A revised key for the eight species of Paratopula known from the worker caste is provided. Additionally, the female caste of Rotastruma stenoceps Bolton is described for the first time. The rarity of these two genera are also discussed on the basis of their potentially nocturnal and arboreal habits.

Presentation of Thyroglossal Cyst in Children

Background: Thyroglossal duct cyst a developmental anomaly present as a congenital cervical masses of neck in children.Objectives: To observe its deferent presentation and evaluate among the children.Materials and methods: This observational cross section study conducted among patients of eighteen years of age present with thyroglossal duct cyst between 2007 to 2012 in the department of ENT and Head- Neck surgery, Dhaka Medical College Hospital, Dhaka. All patients were operated by Sistrunk operation under (excision of total cyst and removal median portion hyoid bone) under general anesthesia. All specimens were histo-pathologically confirmed.Results: Among 24 children with thyroglossal cyst, 15 boys and 9 girls with male female ratio 1.67:1, age ranged from 4 years to 18 years (mean 9.46 std ±4.27). Male (mean 7.53±4.01years) child are younger than female (mean 12.67±2.39 years) child. 66.67% male children were below 10 years of age and 88.89% female children were over 10 years of age. According to the presentation site 17(70.83%) cases were juxtra hyoid, 4(16.67%) were suprahyoid and 3 (12.50%) were infrahyoid. 23 (95.83%) were present as midline swelling, only 1(4.17%) was present as left lateral infrahyoid swelling. 4(16.67%) patient were attended as thyroglossal fistulae with history of intervention. 4(16.67%) patient were developed recurrence followed by surgical resection within two years.Conclusion: Thyroglossal duct cyst present as an asymptomatic midline neck mass around the hyoid region in children. Complete resection along with median portion hyoid bone prevents recurrence.J. Paediatr. Surg. Bangladesh 5(2): 45-53, 2014 (July)

Typical food portion sizes consumed by Australian adults: results from the 2011-12 Australian National Nutrition and Physical Activity Survey.

Considerable evidence has associated increasing portion sizes with elevated obesity prevalence. This study examines typical portion sizes of commonly consumed core and discretionary foods in Australian adults, and compares these data with the Australian Dietary Guidelines standard serves. Typical portion sizes are defined as the median amount of foods consumed per eating occasion. Sex- and age-specific median portion sizes of adults aged 19 years and over (n = 9341) were analysed using one day 24 hour recall data from the 2011–12 National Nutrition and Physical Activity Survey. A total of 152 food categories were examined. There were significant sex and age differences in typical portion sizes among a large proportion of food categories studied. Typical portion sizes of breads and cereals, meat and chicken cuts, and starchy vegetables were 30–160% larger than the standard serves, whereas, the portion sizes of dairy products, some fruits, and non-starchy vegetables were 30–90% smaller. Typical portion sizes for discretionary foods such as cakes, ice-cream, sausages, hamburgers, pizza, and alcoholic drinks exceeded the standard serves by 40–400%. The findings of the present study are particularly relevant for establishing Australian-specific reference portions for dietary assessment tools, refinement of nutrition labelling and public health policies.

Features of the female prostate according to age: an autopsy study

INTRODUCTION: The prostate gland plays an important role in male and female reproductive system. Data on this organ have not been fully explored in women since its first description, probably because it is considered a vestigial gland. OBJECTIVE: To correlate the morphology of the female prostate with age in autopsy. MATERIAL AND METHODS: Thirty-two female cadavers, 31 adults and one newborn, underwent dissection of the region corresponding to the prostate for histological analysis. The urethral region was divided into three portions: proximal, median, and distal. All the glands present in the samples were counted. Clinical data were collected, including age and previous diagnosis of menopause. RESULTS: There were no macroscopically visible prostate. Morphological analyses showed glands surrounding the urethra with a stratified epithelium, ranging from squamous to columnar types, with prevalence of basophilic cells and some presenting with secretion inside. A significant correlation with prostate tissue was found between the median and the proximal urethra, as well as between the median and distal urethra, suggesting that when the glandular structures increase in the median region, there is also an increase in the anterior and distal structures. Moreover, a prevalence of the glands in the median urethra was observed in post-menopausal women. CONCLUSION: This study suggests that the number of female prostate glands increases after menopause, with proliferative spread and growth of the median portion to the proximal and distal portions.
