1. a) List of Nematodes collected by Professor Aellen in european Microchiroptera. Additionnal morphological data to the study of Molinostrongylus alatus, M. panousei, M. skrjabini. Description of M. aelleni n. sp. b) Description of M. richardae n. sp., M. benexae n. sp. et M. bauchoti n. sp., parasites of malagasian Molossidae. c) Description of M. colleyi n. sp. and M. owyangi n. sp., parasites of Malaysian Vespertilioninae, and of Allintoschius dunni n. sp., discovered in Myotis mystacinus from Malaysia and Pipistrellus nanus from Africa. 2. Taking into account the characteristics of the synlophe, the 17 species of the genus Molinostrongylus may be divided into five groups, each one being reasonably well characteristic of the genus of their Chiropteran host. 3. The composition of the Trichostrongyloidea fauna of Chiroptera and its relationship with Trichostrongyloidea from other Mammals (Tupaiidae, Pholidotes, Primates, Sciuridés) are analysed. Six groups are separated and divided into two well defined lines: 1) genus Strongylacantha, and 2) 12 genera stemming more or less directly from the Molineinae, 4. The three conical outgrowths at the tip of the female tail which differenciate presently the Anoplostrogylinae from the Molineinae appear to be an unreliable characteristic. The two subfamilies form a complex group which will be better understood if the evolution of the synlophe and that of the caudal bursa of the males are taken into account.

A new system for classifying accessory canal morphology

Ahmed HMA, Neelakantan P, Dummer PMH

PMID: 28635100 DOI: 10.1111/iej.12800

Thorough knowledge of anatomical complexities of the root canal system has a direct impact on the effectiveness of canal preparation and filling, and is an essential prerequisite for successful root canal treatment. A wide range of complex variations in root canal anatomy exists, including root canal configuration type, developmental anomalies and minor canal morphology such as accessory canals and apical deltas. Accessory canals and apical deltas have been associated with pulp disease, primary canal infection, canal reinfection and post-treatment disease. The current definitions of accessory canal anatomy are not standardized and potentially confusing. Given their role in endodontic disease and their impact on treatment outcomes, there is a need to have a simple classification of their anatomy to provide an accurate description of their position and path from the canal to the external surface of the root. The purpose of this article is to introduce a new system for classifying accessory canal morphology for use in research, clinical practice and training.

Takaoka H, Sofian-Azirun M, Ya'cob Z, Chen CD, Lau KW, Low VL, et al.

Acta Trop, 2017 May;169:170-186.

PMID: 28115156 DOI: 10.1016/j.actatropica.2017.01.016

Surveys of pupae and larvae of black flies were carried out in Bali, Lombok, Sumbawa and Flores in the Lesser Sunda Archipelago, Indonesia, where 10 species were known. A total of 14 simuliid species including four new species and five new records of the genus Simulium were collected, bringing the number of species from the Lesser Sunda Archipelago to 19. They are classified into four subgenera: two in Nevermannia, nine in Gomphostilbia, seven in Simulium and one in Wallacellum. One of four new species, Simulium (Simulium) baliense, is described based on females, males, pupae and larvae from Bali and Lombok. This new species, which is placed in the Simulium striatum species-group of the subgenus Simulium, is closely related to S. (S.) argyrocinctum De Meijere from Java and Sumatra, but it is distinguished from the latter species by the smaller number of the male enlarged upper-eye facets and larval abdomen lacking dorsal pairs of conical protuberances. The distribution record of S. (S.) upikae Takaoka & Davies from Flores is corrected as that of S. (S.) eximium De Meijere. Some aberrant characters of the pupal gill filaments of S. (G.) atratum De Meijere, S. (G.) floresense Takaoka, Hadi & Sigit and S. (G.) sunapii Takaoka, Sofian-Azirun & Suana are illustrated. Characteristics of the fauna of black flies in this archipelago are briefly noted. Keys to all 19 species are provided for females, males, pupae and larvae.

Takaoka H, Srisuka W, Low VL, Saeung A

J Med Entomol, 2019 02 25;56(2):408-415.

PMID: 30398654 DOI: 10.1093/jme/tjy180

A man-biting black fly species so far regarded as Simulium rufibasis Brunetti in Thailand was morphologically analyzed. It was found to be almost indistinguishable in the female from S. rufibasis sensu stricto but distinguishable in the male by the slender fore basitarsus and abdominal segments 2, 6, and 7 each with a pair of shiny dorsolateral patches, and in the pupa by the absence of spine-combs on abdominal segment 7 and terminal hooks on segment 9. It is described as a new species, Simulium tenebrosum. Taxonomic notes are given to separate it from all 11 known species of the S. rufibasis subgroup of the Simulium (Simulium) tuberosum species-group. An analysis of the COI gene sequences shows that this new species is distantly separated from the closely related species.

Ayaz S, Ahmad M, Zafar M, Ali MI, Sultana S, Mustafa MRU, et al.

Microsc Res Tech, 2020 Mar;83(3):239-248.

PMID: 31713962 DOI: 10.1002/jemt.23407

The current study deals with the detailed morphology investigation of eight Cypsela species belonging to tribe Cichoreae. The different Cypsela types were described, explained, compared, and their taxonomic significance is discussed in detail. Light microscopy (LM) and scanning electron microscopy (SEM) have been used to highlight quantitative and qualitative characters of underestudied species. Cypsela exhibit great diversity in macro and micromorphological features such as shape, color, length, width, anticlinal and periclinal wall patterns, surface patterns, epicuticular projections. Majority of Cypsela species were brownish in color and their size ranges from 2.16 to 3.98 mm in length and 1.16 to 0.82 mm in breadth. A great diversity in Cypsela shapes like oblanceolate to obovate, obovoid to cylindrical, obvate, narrowly lanceolate were observed. Most of the platelets having epicuticular projections were observed. The surface pattern on the cypsela surface varied from rugose papillate, verrucose papillate, and striated. On the basis of considerable variations observed, the present study can assist as useful constraints at various taxonomic levels. The aim of the present study is to provide a comprehensive description of the Cypsela morphology and to determine the extent to which these micro morphological data can be used as a taxonomic character to delineate various taxa belonging to the tribe Cichoreae.

A new genus and two new species of trypanorhynch cestodes (Tentaculariidae) from the sharksCarcharhinus sorrah(Müller & Henle) andSphyrna lewini(Griffith & Smith) from off the coasts of Malaysia and Mexico

Syst Parasitol, 2020 04;97(2):133-142.

PMID: 32065375 DOI: 10.1007/s11230-020-09904-w

Two new tentaculariid species were found infecting carcharhiniform sharks from off the coasts of Malaysian Borneo and the southwestern coast of the Baja California Sur, Mexico. Both new species exhibit a homeoacanthous heteromorphous basal and a homeoacanthous homeomorphous metabasal armature. Since this hook arrangement is unique within the tentaculariids and the taxonomy in this group deeply depends on the tentacular armature, Reimeriella n. g. is erected to accommodate R. varioacantha n. sp. ex Carcharhinus sorrah (Müller & Henle) and R. mexicoensis n. sp. ex Sphyrna lewini (Griffith & Smith). Unlike R. mexicoensis n. sp., R. varioacantha n. sp. has a pars bothrialis not overlapping the pars bulbosa and the number of testes is higher. Reimeriella mexicoensis n. sp. possesses very large uncinate to falcate hooks in the basal armature, while in R. varioacantha n. sp. these hooks are almost the same in size as the remaining hooks in both the basal and metabasal armature. The latter species is the first tentaculariid species where the metabasal armature very closely resembles an eutetrarhynchid with a heteroacanthous typical homeomorphous metabasal armature and a high number of spiniform hooks per half spiral row (10-11 vs 6-7 in R. mexicoensis n. sp.) in the metabasal and apical armature. This pattern provides further morphological evidence for the close relationship of the Eutetrarhynchoidea and the Tentacularioidea. Reimeriella varioacantha n. sp. enriches the trypanorhynch fauna from off the coast of Malaysian Borneo while R. mexicoensis n. sp. is a novel record of a tentaculariid trypanorhynch from the Mexican Pacific.

Fulltext CFD study on NACA 4415 airfoil implementing spherical and sinusoidal Tubercle Leading Edge

Aftab SMA, Ahmad KA

PMID: 28850622 DOI: 10.1371/journal.pone.0183456

The Humpback whale tubercles have been studied for more than a decade. Tubercle Leading Edge (TLE) effectively reduces the separation bubble size and helps in delaying stall. They are very effective in case of low Reynolds number flows. The current Computational Fluid Dynamics (CFD) study is on NACA 4415 airfoil, at a Reynolds number 120,000. Two TLE shapes are tested on NACA 4415 airfoil. The tubercle designs implemented on the airfoil are sinusoidal and spherical. A parametric study is also carried out considering three amplitudes (0.025c, 0.05c and 0.075c), the wavelength (0.25c) is fixed. Structured mesh is utilized to generate grid and Transition SST turbulence model is used to capture the flow physics. Results clearly show spherical tubercles outperform sinusoidal tubercles. Furthermore experimental study considering spherical TLE is carried out at Reynolds number 200,000. The experimental results show that spherical TLE improve performance compared to clean airfoil.

PMID: 12680929 DOI: 10.1046/j.1365-2915.2003.00410.x

The fleas (Siphonaptera: Pygiopsyllidae) Farhangia quattuordecimdentata sp. n. and Farhangia sedecimdentata sp. n. are described from pygmy squirrels (Prosciurillus spp.), and Nestivalius sulawesiensis sp. n. from murine rodents, all from Sulawesi, Indonesia. Both new species of Farhangia were collected in Central Sulawesi (Sulawesi Tengah); F. quattuordecimdentata sp. n. was recovered mainly from P. murinus, whereas F. sedecimdentata sp. n. was recovered mainly from P. leucomus. These new species are compared with the two previously described species of Farhangia: F. celebensis (Ewing) from P. murinus in North Sulawesi (Sulawesi Utara) and F. sciuri (Ewing) from the tree squirrel Callosciurus prevosti in Sabah (Borneo). Nestivalius sulawesiensis sp. n. was collected from six species of endemic murine rodents in both North and Central Sulawesi. It is compared to the morphologically similar N. pomerantzi (Traub) from Mindanao, which parasitizes murine hosts that are endemic to the Philippines.

J Dent Educ, 2023 Aug;87(8):1089-1098.

PMID: 37164913 DOI: 10.1002/jdd.13236

PURPOSE: To assess the application and accuracy of two systems (Vertucci et al. 1974 and Ahmed et al. 2017) in classifying the root and canal morphology of human dentition among final-year undergraduates, interns, and postgraduate dental students in India.

METHODS: The survey was conducted using physical and online presentation modes in two phases. Phase 1; PowerPoint presentation (PPT), describing the most used classification system (Vertucci et al. 1974) and its supplementary types and Ahmed et al. (2017) classification. A single presenter delivered the PPT to participants, using either a projector in an auditorium/seminar hall (face-to-face) or an online platform (zoom meeting software). Phase 2 involved determining the students' responses. A questionnaire was distributed amongst the participants after the lecture and collected for analysis. Fisher's exact test was used to analyze the data statistically, and the significance level was set at 0.05 (p

Safety regarding herbal products is very necessary; therefore, routine identification of raw materials should be performed to ensure that the raw materials used in pharmaceutical products are suitable for their intended use. In order for the identification-related data obtained to be accurate, the identification of various kinds of markers is also very necessary. The purpose of this study was to describe the characteristics of Eclipta alba (L.) Hassk. based on qualitative morpho-anatomical markers and quantitative DNA coding. The morphology of this plant has herbaceous habit with a taproot and a stem with branches that appear from the middle. Leaves are single type imperfectly arranged oppositely, lanceolatus, finely serrated on the edges, tapered at the base, pointed at the end, and have a pinnate and hairy leaf surface. The flowers consist of ray flowers and tube flowers with a cup shape. Meanwhile, in terms of anatomy, E. alba has aerenchyma, which are scattered in the cortex of the root and stem. In addition, there are anisocytic stomata, glandular trichomes, and non-glandural trichomes with an elongated shape accompanied by ornamentation found on the leaf epidermis. The results of sequence alignment and phylogenetic tree reconstruction show that the sample plants are closely related to species in the genus Eclipta.
