Before you start this, in the pelvis, removing it from the uterus at Caesarean check the clotting time and platelet count, if the foetus might Section is difficult. Provided the head is well down in the pelvis, an low doses for grand multipara or where there is an uterine operative vaginal delivery, if necessary a destructive one scar. If this fails, repeat the infusion Otherwise, Caesarean Section is the only option, the next day with 25 units in 500ml. If necessary, wait and but even then a hydrocephalus is often so large that you need repeat it after 7days. If this does not work, wait 7days more to drain the head before you can extract it via a routine and try a 3rd time. You may have to use up to 100 units in uterine incision, or you have to make your incision higher, 500ml (the absolute maximum). Usually, much less is larger or maybe even vertical and any of these scars is in necessary. At Caesarean Section, the routine incision was, by a large margin, not large (1);You may have to use large doses. During abdominal closure, the baby who the volume you use, everybody had thought had died, started crying. The baby died 3months later probably from repeated urinary tract (d);keep a fluid balance chart; if there is a positive fluid infections. Mothers of (2) Oxytocin (and misoprostol) can rarely rupture the uterus malformed babies need counselling before delivery if at all possible. Sometimes this is owing to a previous forceful dilatation of the cervix, or to a previous traumatic If delivery is complicated by severe bleeding, delivery. A typical patient gives a history of 2 spontaneous blood, as well as packed red cells and fresh frozen plasma. The first symptom is a watery vaginal discharge, Try compressing the uterus, pack it for 24hrs, and then often followed by a sudden loss of amniotic fluid. This is a useful temporary measure for any Soon afterwards the foetus is delivered, often still alive. When this is happening, it is often too (22-13) and failing this, tie the uterine arteries (22-14). If they are very low that is an quite frequent without an imminent delivery although, indication for administering heparin (paradoxically). The platelet count will rise rapidly; True cervical incompetence is probably quite rare. Do not make this diagnosis too often or you will operate upon many patients unnecessarily. It is not easy to help women with a history of repeated early A course of doxycycline (or erythromycin) & metronidazole miscarriages. These are often the result of some foetal before the next pregnancy or during this pregnancy may abnormality for which nothing can be done. If you do it too late (>24wks), aspirin and low molecular weight heparin are standard, a miscarriage may have already happened. Remember that the benefits of the procedure are related to good selection, especially by Mid-term miscarriages are different. Her pregnancy continued uneventfully until term, congenital malformation of the uterine cavity. As in early pregnancy, inserted the suture was on leave, and it was not noticed by the duty team. She complained of severe pain during the second stage of labour, but this often no cause can be found. Labour proceeded normally, and she delivered a live baby repeated mid-term miscarriages depends on the cause, without help. Immediately after delivery she complained of urinary and is excellent if syphilis can be treated, or cervical incontinence and collapsed. On examination 2months later in another hospital she was found to have a high 1cm vesicovaginal fistula, which was Hypertension and diabetes are more difficult to treat, contiguous with the cervix, which was torn and ragged. Preferably insert the suture at 14wks, when the danger of an early miscarriage is passed. Insert a #2 monofilament nylon (or special cerclage suture) superiorly in the outer surface of the cervix, near the level of the internal os, about 3mm under the surface of the cervix staying more or less at the same depth in the cervix for 90-120 and then let your needle come out. Continue to reinsert the sutures in the cervix near the place where your previous insertion exited the cervix at regular intervals as shown, so as to encircle it. Then tighten the suture round the cervix and knot in such a way that when it is tightened it would still be easy to insert scissors between the knot and the cervix. This is so that, later at 37wks or when in labour, you can cut on one side of the knot.

The number of overweight children is increasing so rapidly that there is an urgent need to identify risk factors for obesity in order to prevent further increases and to identify possible intervention strategies. Apart from the likelihood that these children will remain overweight throughout adolescence and their entire adult life, the consequences of childhood obesity are now beginning to be fully understood. Being overweight has a negative effect on the psycho- logical wellbeing of the child and studies have shown that overweight children have a lower health-related quality of life [7], as well as poorer educational and social outcomes as compared to children of normal weight [8]. Direct health consequences of being an overweight child 298 include an increased risk of type 2 diabetes, which is now being seen in adolescents due to the pediatric obesity epidemic [9]. Studies have also linked being overweight in childhood with increased risk of impaired glucose tolerance and cardiovascular disease in later life [10]. Although it is well established that the risk of an individual developing obesity is dependent upon the interaction between their genotype and lifestyle factors such as an energy-rich diet and sedentary behavior, it is becoming clear that these are not the sole causes of the obesity epidemic. Whilst there is a genetic component related to the ways that genes can favor fat accumulation in a given environment (Table 15. The Dutch Hunger Winter provides an example of how the timing of nutritional constraint during pregnancy is important in determining the future risk of disease. Small babies who were born at term and undergo early catch-up growth, characterized by a greater accumulation of fat mass relative to lean body mass, have a particularly increased risk of becoming obese in later life compared to those born at higher birth weights [14]. Early catch-up growth in infants born preterm and who were fed formula milk is also associated with an increased cardio-metabolic risk in later life [15], including obesity. A number of studies have shown a greater incidence of obesity in adults who were formula-fed as opposed to breast-fed during infancy. Dorner and Plagemann [17] have reported that children of obese women are themselves more likely to become overweight and develop insulin resistance in later life. Gestational weight gain irrespective of prepregnancy weight is positively associated with greater childhood adiposity [18] and even moderate weight gain between successive pregnancies has been shown to result in 302 an increase in large-for-gestational-age births [19]. However, maternal weight loss through bariatric surgery prevents transmission of obesity to children compared with the offspring of mothers who did not undergo the surgery and remained obese [20]. These data suggest that even within a relatively normal dietary range, modest alterations can affect the development of the fetus [21]. However, it is possible that these correlations may not be due to an intrauterine effect but result from shared socioeconomic lifestyle factors between the mother and offspring or the transmission of genetic factors. However, these studies were all relatively small and may have lacked sufcient power. The thrifty phenotype hypothesis proposes that reduced fetal growth is associated with a number of chronic conditions in later life [25]. These conditions include coronary heart disease, stroke, diabetes, and hypertension. This increased susceptibility is proposed to result from adaptations made by the fetus in utero due to its limited supply of nutrients. The hypothesis is that poor nutrient supply in utero results in fetal adaptations such that the infant will be prepared for survival in an environment in which resources are likely to be limited, resulting in a thrifty phenotype. Those with a thrifty phenotype who actually develop in an afuent environment may be more prone to metabolic disorders, such as obesity and type 2 diabetes, whereas those who have received a good nutrient supply in utero will be adapted to good conditions and therefore better able to cope with rich diets. This idea is now widely accepted and is a source of concern for societies such as those in the developing world where rapid socioeconomic improvement is underway resulting in a transition from sparse to adequate or good nutrition [26]. Animal models have been useful in understanding the effects on adult phenotypes resulting from perturbations in the developmental environment. The induction during early life of persistent changes to the phenotype of the offspring by perturbations in maternal diet implies stable alteration of gene transcription which, in turn, results in the altered activities of metabolic pathways and homeostatic control processes. Initially using a candidate gene approach many groups reported long-term changes in the expression of key metabolic genes in response to variations in maternal diet. More recently genome-wide approaches have been used to determine which genes are altered in response to diet. This change in a relatively small subset of genes suggests that these may represent an orchestrated response to the nutritional challenge and be part of an adaptive response [46]. The alterations in offspring metabolism and physiology induced by maternal protein restric- tion are dependent upon the timing of the nutritional challenge. Animal studies have also shown a clear interaction between the pre- and postnatal environ- ments [48,49], with variations in the diet fed after weaning exacerbating the effects of maternal undernutrition on the phenotype of the offspring. Offspring born to dams fed this diet during pregnancy are signicantly smaller at birth than control offspring. These metabolic alterations are all augmented by feeding a high-fat postnatal diet [52]. In guinea pigs fed 85% of an ad libitum diet throughout gestation, alterations in postnatal cholesterol homeostasis were observed in the male offspring [53].

Widespread use of insecticides proven 200 mg celebrex, fungicides and pesticides for crop protection undoubtedly has damaging effects on the environment and hence it is important to improve the control of pests and diseases by genetic means cheap celebrex 200 mg amex. Genetic modification of plants is an attempt for ecofriendly measures against environmental degradation. Through genetic modification, the oil-producing soya bean was tailored to produce a wide range of industrial lubricants, cosmetic compounds and detergents that are biodegradable. A whole new area of biotechnology has been opened up and plants are made to synthesize many novel substances including functional human antibody fragments. Practical application of genetic transformation m By genetic manipulation, it is possible to obtain plants with insecticidal property. This is mainly due to biological activities - bruising, heat and cold damage in soft fruits and vegetables. In tomato the enzyme polygalactronase breaks down cell wall constituents, thus leading to softening of the fruit during ripening. By inhibiting the polygalactronase by antisense genes the tomato can remain dormant fresh until mature and be transported in a firm solid state. The bacterial strain called the superbug was produced on a large scale in laboratory, mixed with straw and dried. When the straw was spread over oil slicks, the straw soaked up the oil and bacteria broke up the oil into non-polluting and harmless products. In this way, pollution of land and water due to the oil slicks can be remedied and the phenomenon is called bioremediation. It is defined as the use of living microorganisms to degrade environmental pollutants or prevent pollution. Benefits from release of genetically modified microorganisms into the environment. One of the following process is employed to introduce a foreign gene into a cell a. Plant tissue culture and its application Plant tissue culture Growing the plant cells, tissues and organs on a artificial, synthetic medium under controlled conditions is called plant tissue culture. Concept The basic concept of plant tissue culture is totipotency, differentiation, dedifferentiation and redifferentiation. Totipotency The inherent potential of any living plant cell to develop into entire organism is called totipotency. Differentiation The meristematic tissue is differentiated into simple or complex tissues. Dedifferentiation Reversion of mature tissue into meristematic state leading to the formation of callus is called dedifferentiation. Redifferentiation The ability of the callus to develop into shoot or root or embryoid. The origin and development of plant tissue culture The beginning of plant tissue culture was made as early as 1898, when a German Botanist G. Haberlandt successfully cultured individual plant cells, isolated from different tissues. But only during 1934 to 1939, a foundation of plant tissue culture was laid down by three scientists (Gauthret, White and Nobecourt) due to discovery of plant growth regulators such as auxins and vitamins. During next twenty years (1940 to 1960) a variety of growth regulator such as cytokinins were identified for their effect on cell division, growth and differentiation. After 1960, in vitro culture of plant cells, tissues and organs was reasonably well developed. Consequently, media and culture techniques for a variety of plant materials became known, which are now extensively Pot plant utilised in all areas of plant improvement programmes. Culture vessels Surface The culture vessels used for sterilization plant tissue studies includes Erylenmayer flask (conical flask), petri plates and culture tubes (25 x Inoculation 150mm). Callus The culture medium is closed with Plantlets cotton plug/ or aluminium foil sheet. Sterilization Sterilization is the technique Pot plants employed to get rid of the microbes such as bacteria and fungi in the Transferred to field (Hardening) culture medium and plant tissues. Chemical sterilization By treating the inoculum in any one of the chemical sterilizant such as Sodium hypochlorite, Calcium hypochlorite, Mercury chloride for 15 to 20 minutes followed by repeated washing in sterile water upto 3 to 5 times. The inoculation is carried out under aseptic condition for which an apparatus called laminar air flow chamber is used. Flamed and cooled forceps are used for transfer of plant materials to different culture media kept in glasswares. Incubation o The culture medium with the inoculum is incubated at 26 2 C with the light intensity at 2000 to 4000 lux (unit of intensity of light) and allowing photoperiod of 16 hour of light and 8 hours of darkness. Induction of callus Due to activity of auxins and cytokinins, the explant is induced to form callus. The mechanism of callus formation is that auxin induce cell elongation and cytokinin induces cell division as a result of which masses of cells are formed. Morphogenesis Formation of new organs from the callus under the influence of auxin and cytokinin is called morphogenesis.
