Abstract The sexing of species is an important tool for population management. In tortoises and turtles, sexing is usually done according to secondary characteristics, such as plastron morphology or phallus eversion techniques. In this paper, we present the phallus eversion method and compare its efficiency to other existing techniques. This new method aims at shortening the management time and reducing the physical aftereffects on the animals, fostering the clinical and reproductive management of Geoffroy’s side-necked turtle (Phrynops geoffroanus) and related species. A sample of fifty individuals was taken in the central region of Piauí state, Northeastern Brazil. The proposed method consisted of moving the head from its resting position. The methods achieving a success rate higher than 80% were compared to each other as for the stimulation time required for phallus eversion. The method as here proposed achieved 100% efficiency in the sex determination of specimens with a linear carapace length between 10 and 34 cm. Also, when compared to the second most efficient method, it substantially reduced the time needed for managing the specimens (91%), avoiding possible sequelae in the individuals handled. Resumo A sexagem das espécies é uma ferramenta importante para o manejo populacional. Em tartarugas, cágados e jabutis, a sexagem geralmente é feita de acordo com características secundárias, como morfologia do plastrão ou técnicas de eversão do falo. Neste artigo, apresentamos o método de eversão do falo e comparamos sua eficiência com outras técnicas existentes. Este novo método visa encurtar o tempo de manejo e reduzir os efeitos colaterais físicos nos animais, promovendo o manejo clínico e reprodutivo do cágado-de-barbicha (Phrynops geoffroanus) e espécies relacionadas. Uma amostra de cinquenta indivíduos foi coletada na região central do estado do Piauí, Nordeste do Brasil. O método proposto consiste em remover a cabeça de sua posição de repouso. Os métodos que obtiveram índice de sucesso superior a 80% foram comparados entre si quanto ao tempo de estimulação necessário para a eversão do falo. O método aqui proposto alcançou 100% de eficiência na determinação do sexo de espécimes com comprimento de carapaça linear entre 10 e 34 cm. Além disso, quando comparado ao segundo método mais eficiente, reduziu substancialmente o tempo necessário para o manejo dos espécimes (91%), evitando possíveis sequelas nos indivíduos manuseados.

Behind the veil – exploring the diversity in Phallus indusiatus s.l. (Phallomycetidae, Basidiomycota)
2019
Studies have demonstrated that many cosmopolitan species actually consist of divergent clades that present high levels of morphological stasis throughout their evolutionary histories. Phallus indusiatus s.l. has been described as a circum-tropical species. However, this distribution may actually reflect the lack of taxonomic resolution due to the small number of diagnostic morphological characters, which leads to the identification of new records as populations of P. indusiatus . Here, we examine the diversity of P. indusiatus -like species in Brazilian Amazonia. We show a clear congruence between detailed morphological data and ITS, nuc-LSU and atp 6 based phylogenetic analyses and three new species are described within the Brazilian indusiate clade. These results highlight the importance of more detailed investigation, with the inclusion of molecular information, in Neotropical fungi.

On the Psychodynamics of Wearing a Headscarf Among Young Muslim Women Living in Germany—New Heterogeneous Poles of Subjectivity
2024
The wearing of a headscarf and the veiling especially of the female face or the whole body is a universal phenomenon that occurs in different eras and in different regions and cultures. Today, wearing a headscarf has become a symbol of Islam, especially in Western countries, and is often met with Islamophobic rejection. In our study, using a qualitative interview, we questioned 25 young Muslim women of Turkish origin (between 18 and 25 years old, n = 25) living in Germany about their reasons for wearing or not wearing a headscarf and their experiences on account of this decision. The majority (n = 16) of the predominantly academically educated female participants do not wear a headscarf, primarily for reasons of female attractiveness, an internalized religiosity, and as an expression of the disintegration of the family hierarchy. All female respondents (n = 7) from families with divorced parents do not wear headscarves, while for the other female respondents (n = 9) who do not wear headscarves, the family seems to have a more liberal mindset. Reasons for wearing a headscarf are especially a religious attachment to Islam, fashionable self-confidence, and the wish to combine Western emancipation with the traditional dress code (in the form of a hybrid identity). These findings are considered against the background of a psychoanalytic reading of the Quranic suras on veiling (according to F. Benslama) and the Lacanian dialectic of the imaginary and symbolic phallus. The diversity of personal reasons can be described with the concept of a heterogeneous subjectivity, which arises from the clash of Western secular and Turkish-Islamic notions.

Moustache for All: Do you have? Can you have? A Study of Roles, Stereotype, Crisis of Masculinity and Identity
2019
Most people believe in a statement that ‘All men are same’, even most men have taken this thing for granted that at the end they are going to be entitled to the same statement. So most of them hardly try to question the basis of the same. A few men engaged in humanities or social sciences are aware of things otherwise most of the men merely step in this tangled zone of masculinity-femininity or the bigger picture as gender. It has been taken for granted that gender studies mean women studies, homosexuality is not even landed yet, there are no such concepts like masculinity/femininity/gender-inequality etc. Without questioning or inquiring the system, blindly believing later following whatever one has been asking to perform is the current state of role-performance of the society. Forget about gender equality. Still, men are not aware of how their deeds disadvantage their female counterparts. The paper investigates the ways in which sex-roles were assigned/imposed, implied and performed and these sex-roles/stereotypes lead to identity assertion, conflict, violence etc. that results into disadvantaging women from their fundamental rights.

On the basis of morphological and molecular analysis of several specimens of Lysurus periphragmoides collected in Argentina, the examination of materials collected in the type locality of Simblum sphaerocephalum (nowadays known as L. periphragmoides), also collected in Argentina (Córdoba), and the examination of specimens of L. periphragmoides from the old world, we conclude that Argentinean and South American material identified and synonymized to L. periphragmoides by Dring in 1980 should be emended as L. sphaerocephalum. As this species lacks type material designated on its protologue, and there is no type material either, we propose a lectotype and an epitype for L. sphaerocephalum. On the basis of species descriptions found in literature, we constructed a table with relevant differences between these two species: L. periphragmoides and L. sphaerocephalum. We fully describe L. sphaerocephalum, including lecto- and epitypes, and its position within the Lysuraceae clade. This work also includes descriptions and images of Blumenavia rhacodes, Itajahya galericulata, L. cruciatus, and Phallus indusiatus from Argentina, with the aim of expanding our knowledge of their distribution ranges in the studied regions.

Congenital Pseudodiphallia –A Rare Case Presentation
2023
Diphallia (penile duplication) is a rare congenital malformation with an incidence of about 1 per 5-6 million newborns. The severity of diphallia varies from a small accessory penile-like tissue to complete true penile duplication with other deformities, usually involving the urogenital, gastrointestinal, and musculoskeletal systems. Pseudodiphallia, as a rare kind of diphallia, is characterized by a small accessory penile-like tissue without a normal penile anatomy structure. A 5.5-year-old male child was brought to the pediatric surgery outpatient department by the parents with complaint of difficulty in retracting the prepucial foreskin and the presence of some growth near the glans. There were no other complaints in specific. Clinical examination revealed foreskin retractable with difficulty and small conical lump smaller than the original glans approximately size ~1 cm diameter at the base attached horizontally at the left side of the original glans at the coronal sulcus and visible incomplete clefting in between the 2 glans visible from the aerial view. After approval from anesthetist, the patient was operated under general anesthesia by excision of pseudodiphallia. Urethral catheterization and circumcision of the penis after taking informed parental consent. Postoperatively, the period was uneventful. The patient responded well to the symptomatic treatment and was orally allowed on the same day evening. Urinary catheter was removed on 5
postoperative day. The patient was discharged on oral symptomatic medication and was advice for follow-up.

Seeking Sanctuary brings together poignant life stories
from fourteen lesbian, gay, bisexual and transgender (LGBT)
migrants, refugees and asylum seekers living in Johannesburg. The
stories, diverse in scope, chronicle each narrator's arduous
journey to South Africa, and their corresponding movement towards
self-love and self-acceptance. The narrators reveal their personal
battles to reconcile their faith with their sexuality and gender
identity, often in the face of violent persecution, and how they
have carved out spaces of hope and belonging in their new home
country. In these intimate testimonies, the narrators' resilience
in the midst of uncertain futures reveal the myriad ways in which
LGBT Africans push back against unjust and unequal systems.
Seeking Sanctuary makes a critical intervention by showing
the complex interplay between homophobia and xenophobia in South
Africa, and of the state of sexual orientation and gender identity
(SOGI) rights in Africa. By shedding light on the fraught
connections between sexuality, faith and migration, this
ground-breaking project also provides a model for religious
communities who are working towards justice, diversity and
inclusion.

Feline infectious peritonitis (FIP) is a fatal disease driven by feline coronavirus induced immune dysregulation and excessive inflammatory cytokine production. Immunomodulatory agents capable of rebalancing this response are therefore of increasing interest. Phallus indusiatus (P. indusiatus), an edible mushroom containing diverse bioactive compounds, has previously demonstrated antiviral and anti-inflammatory potential. This study investigated the immunomodulatory effects of P. indusiatus extract on peripheral blood mononuclear cells (PBMCs) from healthy cats and FIP cats and characterized its chemical constituents using liquid chromatography coupled with tandem mass spectrometry (LC–MS/MS). PBMCs were isolated from whole blood and FIP fluid. Cytotoxicity screening identified 19 µg/mL as a non-toxic concentration for subsequent assays. Cytokine responses (IL-1β, IFN-γ, and IL-10) were evaluated following LPS stimulation in PBMCs from whole blood and under basal conditions in PBMCs from FIP fluid after treatment with P. indusiatus extract and dexamethasone. LC–MS/MS profiling combined with STITCH analysis was used to identify bioactive metabolites and their predicted molecular targets. PBMCs derived from FIP fluid exhibited markedly elevated IL-1β and IFN-γ, indicating strong baseline immune activation. P. indusiatus significantly reduced IL-1β and IFN-γ in PBMCs from FIP fluid and suppressed LPS-induced IL-1β and IL-10 in whole-blood PBMCs, demonstrating immunomodulatory patterns comparable to dexamethasone. LC–MS/MS analysis identified compounds including adenosine, phenylalanine, tyrosine, cystathionine, arginine, and sialic acid, which were linked to inflammatory signaling. Overall, the extract exhibited context-dependent modulation of pro- and anti-inflammatory cytokines, suggesting that P. indusiatus may serve as a promising natural adjunctive candidate for managing immune imbalance in cats with FIP.

Rereading the Secundinus Stone from Vindolanda
2024
Meyer, Mullen, and Vanhala analysed the inscription SECVNDINVS CACOR accompanying the carving of a phallus on a stone excavated at Vindolanda and explained CACOR as the present passive of the verb cacare ‘to shit out’. I suggest that CACOR may have been intended in abbreviation of CACORVM, the neuter genitive plural of the adjective cacus, a transliteration of the Greek κακός ‘evil’, and that the phallus is depicted ejaculating over this word to symbolise its apotropaic power over evil.
