Human-made hydrocarbon-rich environments are important reservoirs of microorganisms with specific degrading abilities and pathogenic potential. In particular, black fungi are of great interest, but their presence in the environment is frequently underestimated because they are difficult to isolate. In the frame of a biodiversity study from fuel-contaminated sites involving 30 diesel car tanks and 112 fuel pump dispensers (52 diesel and 60 gasoline, respectively), a total of 181 black fungal strains were isolated. The long cold incubation (LCI) of water-suspended samples, followed by plating on Dichloran Rose Bengal Chloramphenicol Agar (DRBC), gave isolation yields up to six times (6.6) higher than those of direct plating on DRBC, and those of enrichment with a phenolic mix. The sequencing of ITS and LSU-rDNA confirmed the dominance of potentially pathogenic fungi from the family Herpotrichiellaceae and Exophiala xenobiotica. Moreover, other opportunistic species were found, including E. opportunistica, E. oligosperma, E. phaeomuriformis, and Rhinocladiella similis. The recurrent presence of E. crusticola, Knufia epidermidis, Aureobasidium melanogenum, Cladosporium spp., and Scolecobasidium spp. was also recorded. Interestingly, 12% of total isolates, corresponding to 50% of taxa found (16/32), represent new species. All the novel taxa in this study were isolated by LCI. These findings suggest that black fungal diversity in hydrocarbon-rich niches remains largely unexplored and that LCI can be an efficient tool for further investigations.

The novel Sepertiga Malam di Manhattan by Arumi E is very interesting to study. This novel is a novel about the struggle of a family to get happiness. This novel is the Arumi E's 27th newest novel. The struggle in this novel is to make the family happy, expecting for the baby. Before writing the novel, Arumi E did a research in the places written in the novel to achieve a very interesting fictional story and most of this story was taken from the traveling results so it was so interesting. The objective of this research is to describe (1) the Autopoetic System in the novel Sepertiga MalamdiManhattan by Arumi E. (2) The differentiation system in the Novel Sepertiga Malamdi Manhattan by Arumi E.The research method used is in the form of a descriptive qualitative method that uses a social system approach. The method used by the researcher is the dialectical method. The data source used in this research is the novel Sepertiga Malamdi Manhattan by Arumi E, published by Gramedia publisher in 2018. The data collection in this study uses the steps of reading the novel. To collect data, the researcher use any instrument.There are two results of the study: (1) The autopoetic system in the novel Sepertiga MalamdiManhattan by Arumi E. is concerning to some characters who have their own beliefs or rules in their lives who do not want to follow the rules of others, they are more confident in their own way to success and purpose of life. (2) The system of differentiation in the novel Sepertiga Malamdi Manhattan by Arumi E. is covering the handling of changes in the environment, the characters are able to adapt to the new environment, which has a different culture from the original culture. This shows evidence of the system autopoetic and differentiation in the novel Sepertiga MalamdiManhattan by Arumi E.

Critical Consideration

Initially, Oliver Twist (1839) might seem representative of the archetypal male social plot, following an orphan and finding him a place by discovering the father and settling the boy within his inheritance. But Agnes Fleming haunts this narrative, undoing its neat, linear transmission. This reconsideration of maternal inheritance and plot in the novel occurs against the backdrop of legal and social change. I extend the critical consideration of the novel's relationship to the New Poor Law by thinking about its reflection on the bastardy clauses. And here, of course, is where the mother enters. Under the bastardy clauses, the responsibility for economic maintenance of bastard children was, for the first time, legally assigned to the mother, relieving the father of any and all obligation. Oliver Twist manages to critique the bastardy clauses for their release of the father, while simultaneously embracing the placement of the mother at the head of the family line. Both Oliver and the novel thus suggest that it is the mother's story that matters, her name through which we find our own. And by containing both plots – that of the father and the mother – Oliver Twist reveals the violence implicit in traditional modes of inheritance in the novel and under the law.

In the mid- to late 1950s, Pamela emerged as a critically acclaimed novelist, particularly after the family returned to London. In perhaps her best-known novel, The Unspeakable Skipton, she explores the life of a paranoid writer who sponges on English visitors to Bruges. The novel was hailed for its wit and sensitive depiction of the life of a writer. She also published a fine study of a London vicar martyred in marriage to a vain and selfish wife: The Humbler Creation is remarkable for its incisive and empathetic depiction of male despair. The Last Resort sealed her distinction as a brilliant novelist of domestic life in its frank depiction of male homosexuality. While continuing to publish fiction, Pamela maintained her reputation as a deft reviewer. In 1954, she and Charles travelled to the United States—the first of many trips that were to follow.

‘Me!’ cried Fanny … ‘Indeed you must excuse me. I could not act any thing if you were to give me the world. No, indeed, I cannot act.’ At the age of ten, Fanny Price leaves the poverty of her Portsmouth home to be brought up among the family of her wealthy uncle, Sir Thomas Bertram, in the chilly grandeur of Mansfield Park. There she accepts her lowly status, and gradually falls in love with her cousin Edmund. When the dazzling and sophisticated Henry and Mary Crawford arrive, Fanny watches as her cousins become embroiled in rivalry and sexual jealousy. As the company starts to rehearse a play by way of entertainment, Fanny struggles to retain her independence in the face of the Crawfords’ dangerous attractions; and when Henry turns his attentions to her, the drama really begins… This new edition does full justice to Austen’s complex and subtle story, placing it in its Regency context and elucidating the theatrical background that pervades the novel.

Physiological Tests

Two novel anamorphic yeast strains (S-15LT and 3-C1) were isolated from the inflorescences of plants collected in two different towns in Rajasthan State, India. Sequencing of the D1/D2 domains of the large-subunit (LSU) rDNA and the internal transcribed spacer (ITS) regions suggested they are strains of the same species. Phenotypic characteristics such as the absence of fermentation, the absence of sexual structures and ballistoconidia, the assimilation of myo-inositol and d-glucuronate, and positive Diazonium blue B and urease reactions indicated that these strains belong to the genus Cryptococcus. The novel strains differed from Cryptococcus laurentii in six physiological tests and differed from other related species in more than six tests. A phylogenetic analysis of the sequences of the D1/D2 domains of the LSU rDNA and the ITS regions placed these strains in the Bulleromyces clade within the order Tremellales, with C. laurentii as their closest described relative. The novel strains showed 1.6 and 7.5 % divergence in the D1/D2 domain of the LSU rDNA and ITS regions, respectively, with respect to C. laurentii. The divergence from other species was more than 3 % for the D1/D2 domain and more than 9 % for the ITS region. On the basis of the phenotypic and molecular data, strains S-15LT and 3-C1 represent a novel species within the genus Cryptococcus, for which the name Cryptococcus rajasthanensis sp. nov. is proposed. The type strain is S-15LT (=MTCC 7075T=CBS 10406T).

Peutz Jeghers Syndrome

Abstract Objective To report Peutz–Jeghers syndrome (PJS) cases with non-definitive clues in the family or personal history and finally diagnosed through pathological examination and STK11 gene mutation test. Clinical presentation and intervention PJS was suspected in 3 families with tortuous medical courses. Two of them had relatives departed due to polyposis or colon cancer without pathological results, and the other one had been diagnosed as hyperplastic polyposis before. Diagnosis of PJS was confirmed by endoscopy and repeated pathological examinations, and the STK11 mutation test finally confirmed the diagnosis at genetic level, during which 3 novel mutation were detected (536C > A, 373_374insA, 454_455insGGAGAAGCGTTTCCCAGTGTGCC). Conclusion Early diagnosis of PJS is important and may be based on a family history with selective features among family members, and the pathological information is the key. The novel mutations also expand the STK11 variant spectrum.

AbstractChlamydia gallinacea is an obligate intracellular bacterium that has recently been added to the family of Chlamydiaceae. C. gallinacea is genetically diverse, widespread in poultry and a suspected cause of pneumonia in slaughterhouse workers. In poultry, C. gallinacea infections appear asymptomatic, but studies about the pathogenic potential are limited. In this study two novel sequence types of C. gallinacea were isolated from apparently healthy chickens. Both isolates (NL_G47 and NL_F725) were closely related to each other and have at least 99.5% DNA sequence identity to C. gallinacea Type strain 08-1274/3. To gain further insight into the pathogenic potential, infection experiments in embryonated chicken eggs and comparative genomics with Chlamydia psittaci were performed. C. psittaci is a ubiquitous zoonotic pathogen of birds and mammals, and infection in poultry can result in severe systemic illness. In experiments with embryonated chicken eggs, C. gallinacea induced mortality was observed, potentially strain dependent, but lower compared to C. psittaci induced mortality. Comparative analyses confirmed all currently available C. gallinacea genomes possess the hallmark genes coding for known and potential virulence factors as found in C. psittaci albeit to a reduced number of orthologues or paralogs. The presence of potential virulence factors and the observed mortality in embryonated eggs indicates C. gallinacea should rather be considered as an opportunistic pathogen than an innocuous commensal.

INTRODUCTION: Fungal infections in human skin, such as sporotrichosis, can occur after fish induced trauma. This work aimed to identify fungi in freshwater fish that are pathogenic to humans. METHODS: Extraction of dental arches from Serrassalmus maculatus (piranha) and Hoplias malabaricus (wolf fish), stings from Pimelodus maculatus (mandis catfish), dorsal fin rays from Plagioscion spp. (corvina) and Tilapia spp., for culture in Mycosel agar. Some cultures were submitted to DNA extraction for molecular identification by sequencing ITS-5.8S rDNA. RESULTS: Cultures identified most yeast as Candida spp., while sequencing also permitted the identification of Phoma spp. and Yarrowia lipolytica. CONCLUSIONS: While the search for S. schenckii was negative, the presence of fungus of the genera Phoma and Candida revealed the pathogenic potential of this infection route. The genus Phoma is involved in certain forms of phaeohyphomycosis, a subcutaneous mycosis caused by dematiaceous fungi, with reports of infections in human organs and systems. Traumatizing structures of some freshwater fish present pathogenic fungi and this may be an important infection route that must be considered in some regions of Brazil, since there are a large number of a fisherman in constant contact with traumatogenic fish.

Noa Reich, “Seeing ‘No Guiltless Minds’: Inheritance and Liability in Wilkie Collins’s Armadale” (pp. 30–67) This essay suggests that the articulation of inherited guilt as a type of liability in Wilkie Collins’s Armadale (1866) invites us to reframe inheritance as central both to the Victorian credit economy and to the period’s fictional engagements with the effects of this economy. I begin by examining mid-nineteenth-century legal and political debates about limited corporate liability and estate debts, as well as legal theorist Henry Sumner Maine’s account of succession in Ancient Law (1861), which rests on an analogy between the family and the corporation. With their tropes of transmitted guilt, these discussions point to anxieties arising from the law’s construction of inherited identity as simultaneously individual and intergenerational, a paradox that both refracts and challenges nineteenth-century liberal contractual notions of identity. Armadale explores these issues through its depiction of the testator-heir dynamic as indeterminately singular and double, its association of inheritance with speculative ventures and impersonation, and its vacillation between affirming and limiting intergenerational liability. But it also fosters an alternative, mediating form of responsibility, which I call vicarious liability: a substitutive, imaginative liability both prompted and reinforced by the novel’s competing narrative perspectives and shifting or ambiguous focalization, as well as its embedded letters, diaries, and the depiction of reading as a path to identification with another’s guilt. Armadale’s take on inheritance may thus be read as a proposal for what the novel itself offers a hyper-contractual modernity: a framework for engaging in vicarious experiences of liability.
