“…The male genital organs [31], the rumen structure [21] and the branching pattern of the aortic arch [4] have been anatomically studied in the Korean water deer. In the genus Muntjac, the parotid and mandibular glands [1], lingual papillae [2,37], endocrine cells in the gastrointestinal tract [3], Harderian and nictitans glands [28] and facial scent gland [9] have been anatomically and histologically observed.…”

ABSTRACT. In order to gather basic reproductive information of the water deer and Reeves' muntjac, the immunolocalization of the cytoskeleton proteins in the testes and epididymides of these two species was investigated. The distribution pattern of cytoskeletal proteins in these two species was similar. The desmin was detected in the peritubular myoid cells of the testes and the sub-epithelial cells of the epididymal ducts. Vimentin was observed in the myoid cells, Leydig cells and perinuclear region of the Sertoli cells. Intense immunoreactions for α-smooth muscle actin were restricted to the smooth vascular muscle cells and the peritubular myoid cells in the testes. From the present results, it appears that these distribution patterns of cytoskeletal proteins may be common in the cervids. The water deer (Hydropotes inermis) and Reeves' muntjac (Muntiacus reevesi) both belong to the family Cervidae (order Artiodactyla, suborder Ruminantia). The water deer shows anatomical differences from other deer species by phylogenic evidences, including the absence of antlers and the existence of well-developed upper canines in the male [10,24]. There are two subspecies: the Chinese water deer (H. i. inermis) and the Korean water deer (H. i. argyropus). Although the status of the Chinese water deer in China has declined drastically [39], in contrast, the over-populated situation in South Korea has caused various conflicts to human life, including severe agricultural damage.Reeves' muntjac is one of the muntjac species and can be found in southeastern China and Taiwan as their habitat. The males have antlers, and their upper canines are apparent and protrude from the side of their mouths. This species was introduced into Japan as an exhibition animal and naturalized in the southern part of Chiba prefecture between the 1960s and 1980s [6] and onto Izu-oshima island in 1970 [27]. In the genus Muntjac, some studies on their reproduction and growth have been performed [11][12][13][14]. Macroscopic and histological observations of the male reproductive organs of the Korean water deer have been performed and demonstrate that the Korean water deer possesses the same four typical accessory reproductive glands as other ruminant species. Seasonal changes in size and weight of the testis were also clearly noted, and the breeding season of the animal has been shown to be from October to December, when the male reproductive functions are most active [31]. The male breeding season in the Japanese population of Reeves' muntjac has not been clearly reported, however, the parturition has been observed throughout the year in Chiba prefecture, Japan [27].The cytoskeleton proteins are comprised of microfilaments (actins), intermediate filaments (desmin and vimentin), microtubules (tubulin), neuro-filament proteins, glial fibrillary acidic proteins and cytokeratin. Their roles in cellular structure and function include maintaining cell shape and polarity, positioning of intracellular organelles, forming of cytoplasmic extensions and anchoring o...

“…For this purpose, rodents (Sinzinger and Hohenecker 1972;Atalar et al 2003;Aydin 2011), ruminants (Lee and Lee, 1984;Ahn et al 2008), and carnivores (Rochat and Settles 1993;Ricardo et al 2001;Kim et al 2006) have been studied. In addition, pathologic variations of the aortic arch were also investigated in humans and animals (Yarim et al 1999;Yoo et al 2003;Yeri et al 2011), and these variations are reported to be significant occurrences alongside the normal anatomical situation.…”

This study was aimed at determining the vascular architecture of the aortic arch in the Eurasian bittern. For this purpose, the heart arteries of two bitterns were evaluated. The latex injection method was used to observe the branching of the aortic arch. Two brachiocephalic trunks were arising separately from the aortic arch and these arteries were giving to the common carotid and subclavian arteries. One of the thin branches arising from the subclavian artery was the sternoclavicular artery, which was in turn dividing into a sternal and a clavicular artery supplying the thoracic inlet and pectoral muscles. After the branching of the sternoclavicular artery, the axillary arteries were originating from the subclavian arteries. The thickest branch of the subclavian artery was the thoracic artery, which was dividing into internal and external thoracic arteries. Moreover, the brachiocephalic trunks were giving rise to the common carotid arteries and these were running cranially, giving rise to tracheosyringeal branches supplying the trachea and syrinx, thyroid artery, esophageal branches, artery of the comes nervi vagi and vertebral trunk. It is hoped that this study will enhance morphological data on exotic birds since the reports on species-specific vascular morphology in wild birds are insufficient and lacking in detail.

c Efficient cell corpse clearance is critical for health in organisms. Apoptotic cells displaying phosphatidylserine (PS) are recognized by engulfment receptors and ingested through two conserved pathways. In one pathway, engulfment receptor brain-specific angiogenesis inhibitor 1 (BAI-1) or integrin functions upstream of ELMO/DOCK180 and activate the small GTPase Rac1. In the other pathway, engulfment receptor CED-1 or stabilin-2 acts in concert with the adaptor protein GULP to activate Rac1. Stabilin-2, a PS receptor, facilitates phagocytosis of apoptotic cells and mediates the production of anti-inflammatory cytokines. Here, we propose that the stabilin-2 extracellular domain consisting of integrin-binding fasciclin 1 (FAS1) domains coordinates the activities of the two phagocytic pathways via direct interactions with integrin. Interactions between stabilin-2 and integrin were determined using biochemical assays, including coimmunoprecipitation and fluorescence resonance energy transfer (FRET). These interactions appear to have functional relevance, since knockdown of endogenous ␣v␤5 expression or treatment with a function-blocking ␣v␤5 antibody significantly decreased stabilin-2-mediated phagocytosis in the absence of soluble factors. Our data collectively suggest that the engulfment receptors of the two phagocytic pathways communicate with each other to orchestrate engulfment of damaged erythrocytes. Coordinated phagocytic signaling would be advantageous for physiological and pathological circumstances that require rapid clearance of abnormal (apoptotic or aged) cells.
