This study presents the ovarian morphology and the dynamics of the vitellogenesis process in the oocytes of the diplopod Leptodesmus dentellus. The oocytes are arranged in clusters called ovisacs which are distributed in pairs along the midline of the body forming the ovary. Regions similar to the germarium appear paired in the anterior region of the ovary; however, the development of the oocytes of this species does not follow a regionalisation in the reproductive organ. Cells in three developmental stages are found throughout the length of the ovary. Calcium, proteins, lipids and neutral polysaccharides were detected in the oocytes of L. dentellus. The polysaccharides and the proteins found in the oocytes have a double origin: endogenous, with the participation of the germinative vesicle, and exogenous, from follicular epithelium. The origin of the lipids is exogenous, i.e., they are incorporated into the oocytes, probably derived from the perivisceral fat body, which are highly developed in this region. The deposition of calcium is pre-vitellogenic and probably functions as a reserve during the juvenile stages.

AbstractThis study presents the morphology of the ovary, as well as the dynamics of the vitellogenesis process in oocytes of the diplopod Urostreptus atrobrunneus (Spirostreptida, Spirostreptidae). The oocytes are arranged in clusters called ovisacs, which are distributed in a paired way along the body. The ovary is of the panoistic type. Differently from the other species of diplopods, it was observed little calcium in the oocytes of U. atrobrunneus. Lipids and proteins probably have double origin, i.e, endogenous and exogenous, with probable participation of the adjacent perivisceral fat body. The polysaccharides probably have exogenous origin with participation of the follicular epithelium in the synthesis and/or incorporation of these elements.

AbstractPostembryonic developmental stages of naturally occurring populations of Paratylenchus straeleni and P. steineri were studied. In the former species all juveniles had a well developed stylet and pharynx, while the body of the 4th stage juveniles contained numerous dark granules and this is considered the resting stage. In P. steineri the stylet and pharynx were well developed in the 2nd and 3rd stage juvenile, but the 3rd stage juvenile had numerous granules in the body suggesting it is the resting stage. Fourth stage juveniles had no stylets and the pharynx is much reduced. Because some moulting females have the stylet cone of the juveniles being shed together with the juvenile cuticle, it is concluded that the 4th stage is short-lasting. The length of the body, pharynx, tail and genital primordium as well as the index b increases in successive developmental stages. Indices a, c, c' were almost constant in all juvenile stages. The resting juvenile stage characterises species and it should be included in species descriptions for better characterisation of Paratylenchus species. Paratylenchinae: stades de developpement de Paratylenchus straeleni (De Coninck, 1931) et P. steineri Golden, 1961 (Nematoda: Tylenchulidae) - Ont ete etudies les stades de developpement post-embryonnaire de populations sauvages de Paratylenchus straeleni et de P. steineri. Chez la premiere espece tous les juveniles ont un stylet et un pharynx bien developpes alors que le corps des juveniles de 4eme stade contient de nombreux granules fonces; ce stade a donc ete considere comme le stade de quiescence. Chez P. steineri, le stylet et le pharynx sont bien developpes chez le second et troisieme stades juveniles, mais ce dernier montre de nombreux granules a l'interieur du corps, suggerant qu'il constitue le stade de quiescence. Les juveniles de 4eme stade sont depourvus de stylet et le pharynx est tres reduit. Du fait que chez les femelles en train de muer le cone du stylet des juveniles est rejete avec la cuticule des juveniles, il a ete conclu que le 4eme stade n'a qu'une courte duree de vie. Les longueurs du corps, du pharynx, de la queue et du primordium genital de meme que l'index b augmentent en passant d'un stade a l'autre. Les indices a, c et c' sont generalement constants chez tous les stades juveniles. Le stade quiescent des juveniles est caracteristique de l'espece et devrait etre inclus dans les descriptions d'especes pour une meilleure caracterisation specifique des Paratylenchus.

Previously, we have found that the addition of L-ascorbic acid to chitosan enhanced the reduction in body weight gain in guinea pigs fed a high-fat diet. We hypothesized that the addition of L-ascorbic acid to chitosan would accelerate the reduction of body weight in humans, similar to the animal model. Overweight subjects administered chitosan with or without L-ascorbic acid for 8 weeks, were assigned to three groups: Control group (N = 26, placebo, vehicle only), Chito group (N = 27, 3 g/day chitosan), and Chito-vita group (N = 27, 3 g/day chitosan plus 2 g/day L-ascorbic acid). The body weights and body mass index (BMI) of the Chito and Chito-vita groups decreased significantly (p < 0.05) compared to the Control group. The BMI of the Chito-vita group decreased significantly compared to the Chito group (Chito: -1.0 kg/m2 vs. Chito-vita: -1.6 kg/m2, p < 0.05). The results showed that the chitosan enhanced reduction of body weight and BMI was accentuated by the addition of L-ascorbic acid. The fat mass, percentage body fat, body circumference, and skinfold thickness in the Chito and Chito-vita groups decreased more than the Control group; however, these parameters were not significantly different between the three groups. Chitosan combined with L-ascorbic acid may be useful for controlling body weight.

Reproductive  health education should be given since early childhood by using language that is adapted to the stage of development. If you procrastinate and wait until the teenager it is already too late because in the days of the digital era, as now, all the information can be easily accessed by anyone including children early age. If the early childhood misinformed about their reproductive organs it would disrupt the physical and psychological development due to the wrong behavior in caring for and maintaining reproductive organs. Qur’an as the holy book of Muslims describes the steps of reproduction and  imparting education wisely as well as how to apply such education. This kind of education must be in accordance with the conditions of children and there should not be a lie about it We can also use media and methods such as pictures, songs, tap or other visual  media which can give clearer information, so that children can clearly see parts of the body, their characteristics, and how to treat and care them. The impropriate approach in conveying this kind of knowledge will be very dangerous for children. The provision of early age reproductive organs education can prevent the occurrence of deviant behavior as well as protect children from dangerous influence in early childhood development.

Background : The number of DM victims in the world increased year by year. According to Health Elementary Research in 2013  the highest number was in DIY, it was 2,6%. Then, according to Godean I Local Government Clinic data, DM was the second rank of Non-Communicable Disease (NCD) after hypertension. The increasing of DM victims number was connected by the overweight case that was influenced by unhealthy diet and lack ofphysic activities so it caused accumulation of fat tissues. In the next time it can cause complication for the victims. There are three pillars of DM management namely, diet, psychological intervention, and exercises. The first that should be done is exercises. One of them is physic exercises namely DM gymnastic. Its functions are to control blood sugar, lose weight and body fat so cardiovascular disease risk factor can be prevented and fixed. In this research the DM gymnastic was done three times in a week for six weeks in duration time of 30-60 minutes. Objective : Purpose of the research to know the influence of DM gymnastic to the change of fat body percentage of DM type II victims in Godean I Local Government Clinic. Method : Research method this research used quasi-experiment method, the research plan used pre-post design. The population was all of DM type II victims in Godean I Local Government Clinic with the subject number were 24 people. The data analysis used statistic test Paired Sample t Test with the credibility 95%. Result : Result of the research the statistic test Paired Sample t Ttest showed that there were not differences before and after DM gymnastic treatment for six weeks. According to the average of fat body percentage after DM gymnastic treatment was higher than before (32,52% > 32,86%). Conclusion : There was no influence of DM gymnastic to the body fat percentage of DM type II victims in GodeanI Local Government Clinic p = 0,59 or p = >0,05.   Keywords: Gymnastic, Diabetes Mellitus, Fat Body Percentage

Purpose. Increasing the uniformity of distribution of mineral fertilizers and other bulk materials due to the stability of their feed from the body to the spreading working bodies using the top feeder. Methods. The following methods are used to achieve this aim: the method of comparing the differences between individual groups of fertilizers, the method of analyzing the properties of a new technical system, the method of functional inventiveness, and the methods of theoretical and analytical mechanics. Results. The traction body of the conveyor of the upper feed of the body fat body machine for mineral fertilizers and other bulk materials was substantiated and the relationship between the height of its scrapers and the distance between them was established, as well as the nature of the mineral fertilizer pressure on the curvilinear wall of the body. In addition, the design of the advanced body fertilizer spreader is justified, which ensures a stable flow of fertilizers from the body due to the improvement of the top feeder. Conclusions. Because of the conducted researches, the advantages of machines equipped with top feeder are found. They create the conditions for the forced feeding mineral fertilizers and other loose materials from the container to the distribution bodies, which is a prerequisite for their evenness on the surface. With this, the imperfection of known machines with the top feeder constrains their introduction into agricultural production. On this account, a more thoroughly constructed solution of the body feeder of the top feed is substantiated, in which the conveyor provides a stable supply of fertilizers from the body with reduced energy consumption during operation.

Phenomenological Exploration

AbstractThis paper aims to mobilize the way we think and write about fat bodies while drawing on Jean-Luc Nancy’s philosophy of the body. I introduce Nancy’s approach to the body as an addition to contemporary new materialism. His philosophy, so I argue, offers a form of materialism that allows for a phenomenological exploration of the body. As such, it can help us to understand the lived experiences of fat embodiment. Additionally, Nancy’s idea of the body in terms of a “corpus”—a collection of pieces without a unity—together with his idea of corpus-writing—fragmentary writing, without head and tail—can help us to mobilize fixed meanings of fat. To apply Nancy’s conceptual frame to a concrete manifestation of fat embodiment, I provide a reading of Roxane Gay’s memoir Hunger (2017). In my analysis, I identify how the materiality of fat engenders the meaning of embodiment, and how it shapes how a fat body can and cannot be a body. Moreover, I propose that Gay’s writing style—hesitating and circling – involves an example of corpus-writing. The corpus of corpulence that Gay has created gives voice to the precariousness of a fat body's materialization.

The deformed wing virus (DWV) is one of the most common honey bee pathogens. The virus may also be detected in other insect species, including Bombus terrestris adults from wild and managed colonies. In this study, individuals of all stages, castes, and sexes were sampled from three commercial colonies exhibiting the presence of deformed workers and analysed for the presence of DWV. Adults (deformed individuals, gynes, workers, males) had their head exscinded from the rest of the body and the two parts were analysed separately by RT-PCR. Juvenile stages (pupae, larvae, and eggs) were analysed undissected. All individuals tested positive for replicative DWV, but deformed adults showed a higher number of copies compared to asymptomatic individuals. Moreover, they showed viral infection in their heads. Sequence analysis indicated that the obtained DWV amplicons belonged to a strain isolated in the United Kingdom. Further studies are needed to characterize the specific DWV target organs in the bumblebees. The result of this study indicates the evidence of DWV infection in B. terrestris specimens that could cause wing deformities, suggesting a relationship between the deformities and the virus localization in the head. Further studies are needed to define if a specific organ could be a target in symptomatic bumblebees.

Abstract This study provides information on seasonal occurrence of developmental stages of endoparasites infecting three cyprinids in the Nwanedi-Luphephe dams, Limpopo River System. Labeobarbus marequensis (Smith, 1841), Barbus trimaculatus Peters, 1852 and Barbus radiatus Peters, 1853 were investigated seasonally from January 2008 to October 2008. The following larvae of metazoan parasites were collected: Diplostomum sp. from the eyes of L. marequensis and B. trimaculatus; Ornithodiplostomum sp. from the gills of B. trimaculatus; Posthodiplostomum sp. from muscle, skin and fins of B. trimaculatus and B. radiatus; third-stage Contracaecum larvae (L3) from the mesentery fats and on the liver lobes of L. marequensis and B. trimaculatus and gryporynchid cestode larvae from the outer intestinal wall of B. radiatus. All the flukes encountered were metacercariae. Diplostomum sp. and Contracaecum sp. dominated the parasite communities. Their prevalence exhibited seasonal fluctuations with maxima in summer. Factors likely to influence fish infection such as the body size of fish and their condition factors were also briefly considered in this study.

Intercellular Spaces

The follicular epithelium of vitellogenic oocytes from allatectomized females of Rhodnius fails to develop large intercellular spaces when exposed to juvenile hormone (JH) in vitro. This suggests that in the normal animal, the follicle cells require JH at two developmental stages. Differentiation of the cells in the presence of JH represents one requirement, and only those cells which have undergone this initial priming are fully competent to exhibit the second response, the development of intercellular spaces.
