The present study examines anatomy of Gayo mare reproductive organs. This study used three sample of Gayo mare reproductive organs (n= 3) for observation of morphology and morphometric of the mare reproductive organs. The ovarium was fixed in 4% paraformaldehyde solution then followed by histological method and stained using hematoxylin and eosin (HE) and Masson’s trichome (MT). Three mares were observed for diameter and changes overview of uterus during estrous cycle in real time using ultrasound. The results showed that, in general, the anatomy of Gayo mare’s reproductive organs was similar to other mares, but smaller in morphometry. The total length of the Gayo mare’s reproductive tract from labia to apex cornua was 48.00±1.00 cm. Weight of Gayo mare’s left ovary was 19.07±7.70 g and the right was 24.43±0.83 g. Histologically, there was no difference between Gayo mare’s structure and other mares. In cortex uteri there were some follicles surrounded by capillary, various development stages of follicles, healthy follicles, atretic follicle, and corpus albican; while in medulla there were a lot of connective tissues. Ultrasound of the uterus showed the change in diameter during estrous cycle with the largest diameter of corpus uteri was 4.43±0.10 cm in horses with estrous cycle of 21 days and 6.30±0.93 cm in horses with 24 days estrous cycle. In conclusion, the morphometry of Gayo mare reproductive organs are smaller than the other horses and there are differences in diameter of the uterus during the estrous cycle due to the changes of endometrium thickness.

Reproductive Phases

The reproductive cycle of female T, australis is outlined from examination of reproductive organs in situ and from histological techniques on museum specimens collected in Australia, south of latitude 22�S., over the last 88 years. Features of the reproductive tract and ovaries during important repro- ductive phases are described. There is a marked asymmetry of the reproductive organs, only the right ovary and uterine horn being functional. T. australis is monoestrous; there is no indication of marked differences in the timing of reproductive phases between regional populations. A single, deeply embed- ded corpus luteum occupies up to 60% of the ovary and degenerates at about the time of parturition. Apparently, most females, including young of the year, become pregnant each year, and give birth to a single young, usually between mid-December and late January, although occasionally as late as the end of February. Most young are weaned by early May. There is a short anoestrus, which is probably restricted to early lactating females, followed by a relatively long pro-oestrus. Copulation, ovulation and fertilization occur around late August. There is no evidence of hibernation.

Among a sample of seven small Conger, from 58 to 77 cm. in length, obtained from the Plymouth Fish Quay on 31st March, one was found with unsymmetrical reproductive organs. The other six were immature females with the normal pair of ovaries. The abnormal specimen has a right gonad quite similar to the ovaries of females at the same stage of maturity. It is bandlike in form, extending along the whole length of the abdominal cavity. The inner or left side is covered with smooth peritoneal epithelium (mesoarium). The greater part of the surface of the right (outer) side is raised into transverse lamellæ containing the as yet little-developed ova embedded in fat-tissue. For about one to two millimetres from its free edge, the organ consists of a strip of fat-tissue quite free from germinal cells, and there is a similarly constituted longitudinal fold—here and there divided into a subsidiary one—extending parallel to and about 2 mm. from the free edge and bordering the lamellated germinal area. The ovary is 17.5 cm. long, its greatest width 12 mm., and the widest part of the lamellated area is about 7 mm.

Copulatory Behaviour

Exposure of Japanese quail (Coturnix japonica) embryos to oestrogenic substances disrupts sexual differentiation of the reproductive tract of both sexes and impairs the copulatory behaviour of the adult male. To examine whether these effects can be induced by selective activation of oestrogen receptor α (ERα), Japanese quail eggs were injected with various doses of the selective ERα agonist 16α-lactone-oestradiol (16α-LE2). The natural oestrogen 17β-oestradiol (E2) was used as a positive control. Both 16α-LE2 and E2 induced formation of an ovary-like cortex in the left testis (ovotestis) and reduced the size of the right testis in male embryos. The asymmetry in testis size remained in sexually mature males. Both substances induced retention and malformation of the Müllerian ducts in embryos of both sexes and malformed oviducts in juveniles. Male copulatory behaviour was suppressed by embryonic exposure to E2 and the highest dose of 16α-LE2. However, the lower dose of 16α-LE2, which markedly affected development of the reproductive organs, was without effects on behaviour. It can therefore not be excluded that the behavioural demasculinisation at the 100-fold higher dose involved cross-activation of oestrogen receptor β (ERβ). In conclusion, our results suggest that oestrogen-induced disruption of reproductive organ development in Japanese quail can be mediated via ERα, whereas the role of ERα in demasculinisation of copulatory behaviour remains to be clarified.

Boran breed is the most suitable type of cattle breed for arid and semi-arid regions of Ethiopia due to their adaptive characteristics.  Understanding their reproductive anatomy is important for successful reproductive management and has many implications for the application of assisted reproductive technology, and interpretation of physiological changes at different stages of their reproductive cycle. In this study, data of the anatomical structures of the reproductive organs of 20 Boran heifers were measured and characterized at  different stages of reproduction. The mean (±SE) length (L) of the vagina, cervix, and body of uterus were 13.17±2.98 cm, 7.19±1.28 cm, and 6.70±1.08cm, respectively. The mean (±SE) length of the right uterine horn and oviduct was 18.47 ±2.54 and 18.17 ±1.27cm, respectively  and that of the left were 18.05±2.73 and 17.45±1.80 cm, respectively. The mean ±SE weight (W) of right and left ovaries were 2.44±1.51 gm and 2.44±1.51 gm, respectively. The mean ±SE Length x Width x Thickness of the right ovary was 2.10±0.59 x 1.75±0.35 x 0.83±0.36 and that of the left was 1.97±0.41 x 1.58±0.29 x 0.67±0.33 cm. The mean (±SE) weight of the whole reproductive organ (without the vulva) was 301.35±66.34gm. The ovarian size was influenced by the presence of the corpus luteum(CL) usually larger with its presence.

The present observations on the now-extinct Thylacinus are based on the reproductive system of an adult thylacine discovered among the specimens of the Hill collection at the Hubrecht Laboratory in the Netherlands. As in other marsupials, the reproductive tract was characterised by the presence of a uterus duplex and a vaginal complex where the ureters passed dorsally over each lateral vaginal canal to enter the bladder. The lateral vaginal canals each entered a urogenital sinus that terminated in a shallow cloaca. The gross dimensions of the reproductive tract of the thylacine were greater than those of any extant dasyurid marsupial. The distance from the rostral pole of the ovaries to the most caudal extremity of the urogenital sinus measured 25 cm. The distinctive aspects of the reproductive tract included a disproportionate enlargement of the corpus uteri that is without parallel in any other marsupial species. The bodies of the right and left uteri measured 10.4 cm 1.2 cm 0.9 cm and 9.1 cm 0.8 cm 0.7 cm respectively. The rostro-caudal length of the right and left cervices measured 2.7 cm and 1.7 cm respectively. The cervical canals entered the vaginal complex by way of a thick median vaginal septum. The elongated caudal component of the vaginal culs-de-sac lacked a median vaginal septum. As in other dasyurid marsupials, the lateral vaginae and associated vaginal complex were of diminutive proportions in relation to the typical marsupial pattern. The histology of the tract was remarkably good for tissue preserved since 1902 and indicated that the tissues were free of pathological changes. A characteristic marsupial pattern of ovarian folliculogenesis was evident where all but a thin peripheral zone of the cytoplasm of the primary oocyte became vacuolated during the pre-antral stage of ovarian follicle development.

The present study aimed to evaluate the effect of the leaves of Annona senegalensis on morphometric parameters of the female reproductive organs in rabbits. A total of 120 rabbits were divided into four batches A, B, C and D of 30 animals each. Lots B, C an d D received 10, 20 and 30 g leaves of Annona Senegalensis / kg of feed respectively, while lot A (control group) was fed with the staple feed (without Annona senegalensis leaves). At the end of the experiment, the animals were dissected and morphometric parameters of the different genital organs were measured. The results sho wed that the average live weight, the average lengths of the left oviduct and the average lengths of the vagina did not vary significantly between different experimental groups (p> 0.05). On the other hand, the weight of the right ovary, the left and right uterus, right oviduct, vagina and reproductive system varied significantly between batches (p <0.05). , the right oviduct length of Lot D was the longest (15.52 cm ± 2.83) with a shorter right uterus (5.87 cm ± 1.43) compared to other lots.

Oral Hygiene Habits

Oral hygiene is defined as the practice of keeping the mouth clean and healthy, by brushing and flossing to prevent the occurrence of any gum diseases like periodontitis or gingivitis. The main aim of oral health hygiene is to prevent the buildup of plaque, which is defined as a sticky film of bacteria and food formed on the teeth. The coastal guard is an official who is employed to watch the sea near a coast for ships that are in danger or involved with illegal activities. Coastal guards have high possibilities of being affected by mesothelioma or lung cancer due to asbestos exposure. So, a questionnaire consisting of 20 questions was created and circulated among a hundred participants who were coastal guards, through Google forms. The responses were recorded and tabulated in the form of bar graphs. Out of a hundred participants, 52.4% were not aware of the fact that coastal guards have high chances of developing lung cancer and Mesothelioma. 53.7% were aware of the other oral manifestations of lung cancer other than bleeding gums. Majority of the coastal guards feel that they are given enough information about dental hygiene protocols. Hence, to conclude, oral hygiene habits have to be elaborated using various tools in the right manner to ensure better health of teeth and gums.

Buying and selling is a way to transfer land rights according to the provisions in Article 37 paragraph (1) of Government Regulation Number 24 of 1997 concerning Land Registration which must include the deed of the Land Deed Making Official to register the right of land rights (behind the name) to the Land Office to create legal certainty and minimize the risks that occur in the future. However, in everyday life there is still a lot of buying and selling land that is not based on the laws and regulations that apply, namely only by using receipts and trust in each other. This is certainly very detrimental to both parties in the transfer of rights (behind the name), especially if the other party is not known to exist like the Case in Decision Number 42 / Pdt.G / 2010 / PN.Mtp

Visual field asymmetries (VFA) in the encoding of groups rather than individual faces has been rarely investigated. Here, eye movements (dwell time (DT) and fixations (Fix)) were recorded during the encoding of three groups of four faces tagged with cheating, cooperative, or neutral behaviours. Faces in each of the three groups were placed in the upper left (UL), upper right (UR), lower left (LL), or lower right (LR) quadrants. Face recognition was equally high in the three groups. In contrast, the proportion of DT and Fix were higher for faces in the left than the right hemifield and in the upper rather than the lower hemifield. The overall time spent looking at the UL was higher than in the other quadrants. The findings are relevant to the understanding of VFA in face processing, especially groups of faces, and might be linked to environmental cues and/or reading habits.
