In humans, highly polymorphic genes on CHROMOSOME 6 encode the alpha subunits of class I antigens and play an important role in determining the serological specificity of the surface antigen. Class I antigens are found on most nucleated cells and are generally detected by their reactivity with alloantisera. These antigens are recognized during GRAFT REJECTION and restrict cell-mediated lysis of virus-infected cells.
An ENTEROTOXIN from VIBRIO CHOLERAE. It consists of two major protomers, the heavy (H) or A subunit and the B protomer which consists of 5 light (L) or B subunits. The catalytic A subunit is proteolytically cleaved into fragments A1 and A2. The A1 fragment is a MONO(ADP-RIBOSE) TRANSFERASE. The B protomer binds cholera toxin to intestinal epithelial cells, and facilitates the uptake of the A1 fragment.

Characterization of a Caenorhabditis elegans recA-like gene Ce-rdh-1 involved in meiotic recombination. (1/3840)

A recA-like gene was identified in the Caenorhabditis elegans genome project database. The putative product of the gene, termed Ce-rdh-1 (C. elegans RAD51 and DMC1/LIM15 homolog 1), consists of 357 amino acid residues. The predicted amino acid sequence of Ce-rdh-1 showed 46-60% identity to both RAD51 type and DMC1/LIM15 type genes in several eukaryote species. The results of RNAi (RNA-mediated interference) indicated that repression of Ce-rdh-1 blocked chromosome condensation of six bivalents and dissociation of chiasmata in oocytes of F1 progeny. Oogenesis did not proceed to the diakinesis stage. Accordingly, all the eggs produced (F2) died in early stages. These results suggest that Ce-rdh-1 participates in meiotic recombination.  (+info)

Formation of mature egg envelope subunit proteins from their precursors (choriogenins) in the fish, Oryzias latipes: loss of partial C-terminal sequences of the choriogenins. (2/3840)

The inner layer of egg envelope of the medaka, Oryzias latipes, comprises two major groups of glycoprotein subunits, ZI-1,2 and ZI-3. Their precursor proteins, choriogenin H (Chg H) and choriogenin L (Chg L), respectively, are synthesized in spawning female liver. In the present study, the primary structures of the precursors and the corresponding mature subunits were compared by peptide mapping and amino acid sequencing to find what difference in their molecular structures is relevant to the assembly of the soluble precursors into the insoluble inner layer. The primary structures of the solubilized subunits were mostly identical to those of the respective precursors, but they lacked C-terminal partial sequences that their precursors possessed, namely, ZI-1,2 subunit was shorter than Chg H by 34 amino acid residues and ZI-3 was shorter than Chg L by 27 residues. In addition, a consensus amino acid sequence, Arg-Lys-X-Arg, was found at the putative cleavage sites in the C-terminal region of the precursors. It is conjectured that the truncation of the precursor proteins is prerequisite for formation of mature chorion subunit proteins and their assembly into chorion.  (+info)

Fertilization, embryonic development, and offspring from mouse eggs injected with round spermatids combined with Ca2+ oscillation-inducing sperm factor. (3/3840)

Round spermatids, precursor male gametes, are known to possess the potential to achieve fertilization and embryonic development when injected into eggs. However, injection of spermatids alone seldom activates eggs in the mouse, as spermatids by themselves cannot induce an increase in intracellular Ca2+, a prerequisite for egg activation. We injected a mouse round spermatid into an egg simultaneously with partially purified sperm factor from differentiated hamster spermatozoa. The combined injection produced repetitive Ca2+ increases (Ca2+ oscillations) lasting for at least 4 h as observed at fertilization, and induced activation in 92% of eggs. This method provided 75% fertilization success associated with male and female pronucleus formation and development to 2-cell embryos, while only 7% of eggs were fertilized by injection of a spermatid alone. Of the 2-cell embryos, approximately 50% developed to blastocysts during 5 days of culture in vitro, while no blastocysts were obtained following injection of sperm factor alone. Furthermore, the 2-cell embryos, that were created by spermatids and sperm factor and transplanted into foster mothers, developed into normal offspring, although the percentage was only 22%. All infants grew into healthy adults carrying normal chromosomes. The sperm factor served as a complementary factor for successful fertilization by round spermatid injection.  (+info)

Experimental murine schistosomiasis in the absence of B7 costimulatory molecules: reversal of elicited T cell cytokine profile and partial inhibition of egg granuloma formation. (4/3840)

The granulomatous inflammation in infection with the helminth Schistosoma mansoni represents a cellular hypersensitivity reaction mediated by, and dependent upon, MHC class II-restricted CD4+ Th cells sensitized to parasite egg Ags. The current work examines the role and significance of the B7:CD28/CTLA-4 pathway in providing the costimulation necessary for the activation of these pathogenic T cells. In vitro T cell responses in B7-1-/- mice, 7-8 wk postinfection, were no different from wild-type controls, but the absence of B7-2 molecules resulted in a decrease in egg Ag-induced proliferation with increased IFN-gamma production. Both B7-1-/- and B7-2-/- mice exhibited intact granuloma formation. In contrast, CD4+ Th cells from B7-1/2 double-deficient mice displayed a dramatic loss of proliferative capacity upon stimulation with egg Ag. Most strikingly, these T cells secreted only IFN-gamma, but not IL-4 and IL-10, a pattern entirely opposite to that displayed by wild-type controls. Despite these major differences in T cell reactivity, B7-1/2-/- mice had only a limited reduction of granuloma size and fibrosis, without appreciable difference in cellular composition. These results show that substantial granuloma formation can occur under conditions of limited T cell expansion and restricted Th1-type cytokine production. They also support the notion that the combined effect of B7 signaling is not as critical for Th1 cell activation as it is for the development of the Th2 dominant environment characteristic of the evolving schistosome infection in H-2b mice.  (+info)

The RLF-B component of the replication licensing system is distinct from Cdc6 and functions after Cdc6 binds to chromatin. (5/3840)

Replication licensing factor (RLF) is an essential initiation factor that can prevent re-replication of DNA in a single cell cycle [1] [2]. It is required for the initiation of DNA replication, binds to chromatin early in the cell cycle, is removed from chromatin as DNA replicates and is unable to re-bind replicated chromatin until the following mitosis. Chromatography of RLF from Xenopus extracts has shown that it consists of two components termed RLF-B and RLF-M [3]. The RLF-M component consists of complexes of all six Xenopus minichromosome maintenance (MCM/P1) proteins (XMcm2-7), which bind to chromatin in late mitosis and are removed as replication occurs [3] [4] [5] [6] [7]. The identity of RLF-B is currently unknown. At least two factors must be present on chromatin before licensing can occur: the Xenopus origin recognition complex (XORC) [8] [9] and Xenopus Cdc6 (XCdc6) [10]. XORC saturates Xenopus sperm chromatin at approximately one copy per replication origin whereas XCdc6 binds to chromatin only if XORC is bound first [9] [10] [11]. Although XORC has been shown to be a distinct activity from RLF-B [9], the relationship between XCdc6 and RLF-B is currently unclear. Here, we show that active XCdc6 is loaded onto chromatin in extracts with defective RLF, and that both RLF-M and RLF-B are still required for the licensing of XCdc6-containing chromatin. Furthermore, RLF-B can be separated from XCdc6 by immunoprecipitation and standard chromatography. These experiments demonstrate that RLF-B is both functionally and physically distinct from XCdc6, and that XCdc6 is loaded onto chromatin before RLF-B function is executed.  (+info)

Ku-dependent nonhomologous DNA end joining in Xenopus egg extracts. (6/3840)

An extract from activated Xenopus eggs joins both matching and nonmatching ends of exogenous linear DNA substrates with high efficiency and fidelity (P. Pfeiffer and W. Vielmetter, Nucleic Acids Res. 16:907-924, 1988). In mammalian cells, such nonhomologous end joining (NHEJ) is known to require the Ku heterodimer, a component of DNA-dependent protein kinase. Here I investigated whether Ku is also required for the in vitro reaction in the egg extract. Immunological assays indicate that Ku is very abundant in the extract. I found that all NHEJ was inhibited by autoantibodies against Ku and that NHEJ between certain combinations of DNA ends was also decreased after immunodepletion of Ku from the extract. The formation of a joint between a DNA end with a 5'-protruding single strand (PSS) and an end with a 3'-PSS, between two ends with 3'-PSS, and between two blunt ends was most Ku dependent. On the other hand, NHEJ between two DNA ends bearing 5'-PSS was Ku independent. These results show that the Xenopus cell-free system will be useful to biochemically dissect the role of Ku in eukaryotic NHEJ.  (+info)

Purification and characterization of a serine protease with fibrinolytic activity from Tenodera sinensis (praying mantis). (7/3840)

Mantis egg fibrolase (MEF) was purified from the egg cases of Tenodera sinensis using ammonium sulfate fractionation, gel filtration on Bio-Gel P-60 and affinity chromatography on DEAE Affi-Gel blue gel. The protease was assessed homogeneous by SDS-polyacrylamide gel electrophoresis and has a molecular mass of 31500 Da. An isoelectric point of 6.1 was determined by isoelectric focusing. Amino acid sequencing of the N-terminal region established a primary structure composed of Ala-Asp-Val-Val-Gln-Gly-Asp-Ala-Pro-Ser. MEF readily digested the Aalpha- and Bbeta-chains of fibrinogen and more slowly the gamma-chain. The nonspecific action of the enzyme results in extensive hydrolysis of fibrinogen and fibrin releasing a variety of fibrinopeptide. The enzyme is inactivated by Cu2+ and Zn2+ and inhibited by PMSF and chymostatin, yet elastinal, aprotinin, TLCK, TPCK, EDTA, EGTA, cysteine, beta-mercaptoethanol, iodoacetate, E64, benzamidine and soybean trypsin inhibitor do not affect activity. Antiplasmin was not sensitive to MEF but antithrombin III inhibited the enzymatic activity of MEF. Among chromogenic protease substrates, the most sensitive to MEF hydrolysis was benzoyl-Phe-Val-Arg-p-nitroanilide with maximal activity at pH 7.0 and 30 degrees C. MEF preferentially cleaved the oxidized B-chain of insulin between Leu15 and Tyr16. D-Dimer concentrations increased on incubation of cross-linked fibrin with MEF, indicating the enzyme has a strong fibrinolytic activity.  (+info)

A novel 62-kilodalton egg antigen from Schistosoma mansoni induces a potent CD4(+) T helper cell response in the C57BL/6 mouse. (8/3840)

In infection with Schistosoma mansoni, hepatic granuloma formation is mediated by CD4(+) T helper (Th) cells sensitized to schistosomal egg antigens. There is considerable variation among infected individuals with respect to both severity of disease and the T-cell response to egg antigens. In the BL/6 mouse, the egg granulomas are relatively small and the relevant sensitizing egg antigens are largely unknown. We investigated the CD4(+) Th cell response of infected BL/6 mice to egg antigens fractionated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and found a prominent lymphoproliferative response to be directed against a 62-kDa component. With the aid of a specific T-cell hybridoma, 4E6, the 62-kDa antigen was isolated; following partial digestion with endoproteinase Glu-C, an internal amino acid sequence was found to be identical with one present in the enzyme phosphoenolpyruvate carboxykinase (PEPCK) of the organisms Caenorhabditis elegans and Treponema pallidum and to differ by one residue from PEPCK of various other species. In CD4(+) Th cells from 7.5- 8.5-week-infected BL/6 mice, the purified 62-kDa molecule elicited a potent proliferative response which, based on cytokine analysis, was of a mixed Th-1 and Th-2 type. Our results reveal a novel egg antigen of particular prominence in the BL/6 mouse and suggest that the immune response in schistosomiasis is a product of sensitization to egg antigens that may vary considerably in immunogenicity from strain to strain.  (+info)

Its egg season! We tend to forget, because of battery egg farming techniques, that eggs really are a seasonal food - kept in natural lighting conditions, hens lay far fewer eggs in the winter, and more in the spring and summer. Thats why eggs are associated with Easter: Theyve been a symbol of spring since - well, forever.. Between the increased egg yield, and grocery stores running specials for folks planning to dye eggs, eggs are dirt-cheap these days. Right this very minute, a dozen large eggs are on sale at my local Kroger for 66c. (A month or so back, Marsh had medium eggs - common in the early spring - 3 cartons for a buck! I bought 18 cartons!). With prices like this, its a great time to eat eggs, not just for breakfast, but lunch, dinner, and even for snacks. Eggs are endlessly versatile, not only lending themselves to a wide variety of flavors, but letting you create a number of different textures, too. For these reasons, I never get tired of eggs. (As I write this, I have a cheese ...
Egg cells are produced well before birth in a huge number of so called primordial egg cells (primordial oocytes). From the beginning on, there is a continuous process of dying, so that at birth 2 million (!) are left. That process of dying goes on after birth. At the onset of puberty there remain about 40,000 ova. Then every four weeks a number of them begin a process of maturation. Of these, only one (sometimes two or three) ovum matures, the rest dies. In total about 400 ova mature (13 per year for 30 years). At menopause, no primordial egg cells are left ...
To safely feed eggs and eliminate any risk of salmonella and biotic deficiency, it is best to avoid feeding raw eggs to your pooch and prepare it before feeding. You can boil the egg rather than fry it in additional oil or butter, this way not only are eggs safe but your furry buddy will derive numerous health benefits out of it.. So if next time while enjoying your breakfast with super delicious mouthwatering scrambled eggs you wonder can I give my dog scrambled eggs, hold on! Any additional butter, oil, milk or salt, as required for scrambled egg, is, of course, a bit too much for your dog and therefore not healthy, so avoid sharing it with your buddy and rely on simply boiled egg.. One important thing you should know is how often can dogs eat eggs? can dogs eat eggs every day or once a week? You can safely give one egg to your dog a day but more than one is not quite healthy as eggs are high in cholesterol and they do contain enzyme inhibitors which could affect the digestion, especially in ...

First, they extract an unfertilized egg cell from a female and enucleate the cell, or remove its nucleus, which contains the DNA. From the body of the animal to be cloned, they obtain a suitable cell, such as a skin cell, the nucleus of which contains its owners genetic blueprint. They insert this cell [or just its nucleus] into the enucleated egg and pass an electric through it. This fuses the cell with egg cytoplasm. With its new nucleus, the egg now divides and grows as if it were fertilized, and a clone of the creature from which the body cell was taken begins to develop ...

N2 - Biochemical and immunological analysis of unfertilized sea urchin eggs has revealed the presence of at least two distinct isoforms of cytoplasmic dyneins, one soluble and the other microtubule-associated. The soluble enzyme is a 20 S particle with a MgATPase activity that can be activated 5-fold by nonionic detergents. It contains heavy chain polypeptides that 1) comigrate with the dynein heavy chains of embryonic cilia; 2) cross-react with antibodies against flagellar dynein; and 3) are cleaved by UV irradiation in the presence of MgATP and sodium vanadate into specific peptide fragments. The soluble egg dynein is, therefore, closely related to axonemal dynein and may be a ciliary precursor. Egg microtubule preparations contain a distinct dynein-like polypeptide, previously designated HMr-3 (Scholey, ...
At fertilization, the egg must undergo a rise in intracellular Ca 2+ so that embryogenesis may begin. How the sperm signals the egg to release Ca2+ is not well understood. This dissertation examines how the sperm stimulates Ca2+ release in frog and ascidian eggs at fertilization. ^ One secondary messenger used by somatic cells to elicit intracellular Ca2+ release is inositol trisphosphate (IP3). Results from experiments examining Xenopus oocyte maturation indicate that frog oocytes become more sensitive to IP3 as they mature into fertilizable eggs. Because this evidence suggested that IP3 may be important for Xenopus fertilization, frog eggs were injected with an antibody against the IP3 receptor and then inseminated. The inhibitory effect of this antibody on Ca2+ release after insemination indicates that the Ca2+ rise at fertilization in frog eggs requires IP3. ^ Because IP3 is generated by phospholipase C (PLC) enzymes, the role played by PLCs during Xenopus fertilization was investigated. The PLC
The aim of the research was to investigate the impact iodine solution disinfection had on Salmo trutta (L.) egg survival rates during incubation, and to determine the effect of the disinfection procedure on egg shells using scanning microscopy. The study groups were bathed in a Desamar K30 solution at a concentration of 100 ml per 10 dm-3 for 10 m once after the eggs had hardened and four times after the eyed stage. Egg samples for scanning analyses were collected on day 30 of incubation at the eyed stage after the first bath in the iodophor solution, and then at the end of incubation. Egg surface images were analyzed for the number of bacteria, the presence of hyphae, and the egg surface area covered with sediments. No statistically significant differences were noted in embryo survival rates in the groups that were disinfected. The highest number of bacteria was observed on egg surfaces which had not been disinfected prior to hatching. A significant amount of sediment was observed on the eggs ...
Title:Calcium Signaling in Mammalian Eggs at Fertilization. VOLUME: 16 ISSUE: 24. Author(s):Hideki Shirakawa, Takashi Kikuchi and Masahiko Ito. Affiliation:Department of Engineering Science, The University of Electro-Communications Graduate School of Informatics and Engineering, 1-5-1 Chofugaoka, Chofu, Tokyo 182-8585, Japan.. Keywords:Calcium influx, Calcium oscillations, Calcium release, Calcium wave, Egg activation, Fertilization, Fluorescence imaging, Infertility, Inositol 1, 4, 5-trisphosphate, Phospholipase Cζ.. Abstract:The innovation and development of live-cell fluorescence imaging methods have revealed the dynamic aspects of intracellular Ca2+ in a wide variety of cells. The fertilized egg, the very first cell to be a new individual, has long been under extensive investigations utilizing Ca2+ imaging since its early days, and spatiotemporal Ca2+ dynamics and underlying mechanisms of Ca2+ mobilization, as well as physiological roles of Ca2+ at fertilization, have become more or less ...

Masses of cortices of both unfertilized and fertilized sea urchin eggs can be isolated by crushing eggs in hypotonic MaCl2 (0.1 M) solution. The amount of cortical material in terms of protein-N increases steadily after fertilization until the monaster stage and thereafter remains almost constant until well into the two-cell stage. The amount of bound-SH per protein-N of the egg cortex also increases after fertilization, reaches a maximum value at the amphiaster stage and thereafter decreases rapidly as the cleavage of the cell proceeds. ...
At fertilization in sea urchin eggs, CV exocytosis is rapidly triggered (Chandler, 1991; Swann and Whitaker, 1986) and is followed by membrane retrieval (Whalley et al., 1995). That the CVs are docked to the PM in the unfertilized egg can be demonstrated by the ability to purify an intact exocytotic machine (either CSC or IPC) in which the PM and CVs remain tightly associated (Vacquier, 1975). These CVs are resistant to shear stress (Vacquier, 1975; Whalley et al., 1991; Coorssen et al., 1998) and are docked by ultrastructural criteria (Chandler, 1991; Chandler, 1984; Sardet, 1984). In this work we have used a combination of physiological and biochemical techniques to show that one protein, NSF, does not play a role in either CV exocytosis or in CV-CV fusion.. CV exocytosis is susceptible to inhibition by NEM (Haggerty and Jackson, 1983; Vogel et al., 1992; Jackson and Modern, 1990) and other thiol-specific reagents (Whalley and Sokoloff, 1994), which indicates the association of ...
The first issue that an egg and a sperm of any organism type face in successfully producing an embryo is the possibility of polyspermy. Polyspermy is the fertilization of an egg by multiple sperm, and the results of such unions are lethal.. If multiple sperm fertilize an egg, the embryo inherits multiple paternal centrioles. This causes competition for extra chromosomes and results in the disruption of the creation of the cleavage furrow, thus causing the zygote to die. As an important model organism in the study of fertilization and embryonic development, polyspermy in sea urchins has been studied in detail. The sea urchins methods of polyspermy prevention have been broken down into two main pathways. These two primary pathways are known as the fast block and the slow block to polyspermy.. Fast Block. After the sperms receptors come into contact with the eggs jelly layer and the acrosomal enzymes are released and break down the jelly layer, the sperm head comes into contact with the ...

Your daughters white blood count is over one million. We have triple checked the results and after reviewing the slides, the cells we see are consistent with leukemia. On February 7, 2002 with those words we began a journey that is any parents worst nightmare - childhood cancer.. Our beautiful, fun loving 11-year-old daughter, Sarah, was later confirmed to have Acute Lymphoblastic Leukemia (ALL). Although Sarah was considered high risk due to her age, gender, and the extraordinary high white blood count, statistics were in her favor that after a two (2) to five (5) year treatment and recovery period she would be cured. Over the next several months Sarah underwent intense rounds of chemotherapy but never went into remission.. Continuing to fight her battle, Sarah required more high dose chemotherapy, cranial and full body irradiation, and a bone marrow transplant. Sarahs brother James, then 10, was a perfect match and donated a liter of marrow to help his sister. Sarah rallied after the ...
Eggs are readily bought in supermarkets, but a person is lucky to have their very own chickens in the backyard that can provide absolutely fresh eggs. Different breeds of hen have different production rates, but a leghorn is renown for its productivity. A single leghorn hen can lay as many as 300 eggs per year. By the way, hens dont need roosters to lay eggs. Eggs can be white, brown, blue, green or even purple.. Besides their great nutritional value, eggs can be prepared in all kinds of ways. They can be soft boiled, hard boiled, poached, shirred, fried or scrambled. They can be made into omelets and frittattas and can be the basis for sauces like Hollandaise sauce and condiments like mayonnaise. They can even be used in alcoholic drinks like flips and nonalcoholic drinks like eggnog. Custards wouldnt be custard without eggs. Can I get an amen?.

We have examined whether IP3R1 phosphorylation at the MPM2 epitope, an epitope commonly phosphorylated by M-phase kinases, may underpin the enhanced functional activity of IP3R1 in MII eggs. Our results show that MPM2 IP3R1 phosphorylation is associated with the presence of [Ca2+]i oscillations in mouse eggs and zygotes. Using in vitro assays, we found that MAPK/ERK2 phosphorylates IP3R1 at a conserved consensus site and that MAPK activity is required for in vivo MPM2-detectable IP3R1 phosphorylation. We also observed that abrogation of MPM2 IP3R1 phosphorylation during maturation coincides with the failure of eggs to mount [Ca2+]i oscillations. These results establish an unmistakable molecular link between the cell cycle and the Ca2+ releasing machinery.. The role of Ca2+ at fertilization represents, perhaps, the clearest manifestation of cell-cycle regulation by a second messenger, as a sperm-induced Ca2+ response is required to induce cell-cycle progression in all species studied to date ...
Lets start out with eggs nutrition and then well get to the calories in an egg. The protein in eggs is outstanding at 6.3 grams for one large egg. This egg protein is also quickly absorbed by the body (1.5 to 3 hours) and contains over 17 amino acids. Eggs score pretty high in vitamins D, A, Riboflavin and B12 . They are high in minerals as well with one egg providing 28% of the DRI of selenium and 18% of your daily iodine needs. There are approximately 78 calories in one egg.. Eggs are very high in choline. One large egg contains up to 35% of the Daily Recommended Intake suggestions. Choline is considered an essential nutrient. It was once thought the body manufactured all the choline it needed, but current research is proving we need additional choline supplementation to our standard western diet. Choline is a methyl donor, meaning it helps support methylation-one of the most basic processes of life. Building DNA, nerve signaling, and liver detoxification are just some of the bodys ...

Plain and simple, the shape of the egg is the secret! The eggs unique shape gives it tremendous strength, despite its seeming fragility. Eggs are similar in shape to a three-dimensional arch, one of the strongest architectural forms. The egg is the strongest at the top and the bottom (or at the highest point of the arch). If you hold an egg in your hand and squeeze it on the top and the bottom, the egg doesnt break because you are adding pressure to the ends which are the strongest parts of the egg. The curved form of the shell also distributes pressure evenly all over the shell rather than concentrating it at any one point. If you completely surround the egg with your hand and then squeeze, the pressure you apply by squeezing is distributed evenly all over the egg. However, eggs do not stand up well to uneven forces, which is why they crack easily on the side of a bowl (or why it would crack if you just pushed on one side). This also explains how a hen can sit on an egg and not break it, but ...
I dont know where Dr. Behrenbeck of the Mayo clinic got his numbers, but 213 mg is a LOT of cholesterol from a large egg. Thats probably closer to a really big extra-large egg or a smaller jumbo egg.

Sarah Beth had just celebrated her 49th birthday on May 16, 2002. She had been eating healthy, walking three to four miles a day, and lost 22 lbs over a period of three months. Sarah Beth felt great!. On the Friday night before Memorial Day, May 24, Sarah Beth started running a low-grade fever, just enough to make her feel lousy, and had a slight cough. The next morning, however, she had a fever of 102.. Sarah Beth had planned to spend the day with her mother, but decided to stay home. An on call doctor said it was likely viral and to take Tylenol and stay hydrated. The fever would go down and then spike back up to 103 degrees.. Sarah Beths mother came to stay with her at her house, and then Sarah Beth went to bed. Sunday, Sarah Beth was unable to go to church. Her friend Linda checked on her and called the on call doctor, who told her that same thing he had told Sarah Beth, that it was likely viral. But that night, Sarah Beth could not get out of bed, could not eat or drink.. On Monday, Linda ...

B, EGG OR OVUM IN AMPHIOXUS : The mature female sex cell is ovum. It is small and 0.12 mm in diameter. It is a microlecithal egg. The cytoplasm around the nucleus will show yolk. In the peripheral cytoplasm yolk is absent. It is granular and is called carticoplasm. The plasma membrane surrounds the cytoplasm. Around this is a mucopolysaccharide membrane is present. It is called vitelline membrance. In between these two layers perivitelline space is present. The nucleus is present towards the animal pole, where as the opposite pole is called vegetal pole. The vegetal pole becomes posterio dorsal side of the embryo. The Animal pole becomes antero-ventral side of the embryo. Hence a gradient polarity is established in the egg.. FERTILISATION IN AMPHIOXUS : As soon as the egg comes in contact with water the vitelline membrane wilI separate from the plasma membrane.. The egg is surrounded by a number of sperms. One sperm will make its entry through the contents of the egg from the vegetal pole. At ...
In order to retrieve eggs for freezing, a patient undergoes the same hormone-injection process as women do with in-vitro fertilization. The only difference is that once the eggs are retrieved, the eggs are frozen (or banked) for future use. They can then be warmed, fertilized and transferred at a later date.. It takes approximately 4 - 6 weeks to complete the egg freezing cycle. This includes 10 - 14 days of hormone injections to stimulate the ovaries and ripen multiple, mature eggs. As with IVF, the patient would visit the Clinic regularly throughout this period for early morning ultrasounds and blood work. Once it has been determined that the eggs have adequately matured, a retrieval procedure is scheduled in order to have these removed with a needle placed through the vagina and under ultrasound guidance. This procedure is done under conscious sedation and is not generally painful. The eggs are then immediately frozen.. When the patient is ready to attempt a pregnancy (this can be several ...
The day had not gone well for Sarah Whittaker. On top of everything else, she had been made to work half an hour of overtime, to correct a mistake that hadnt even been hers. She was so distracted by her irritation that she didnt notice the strange towering wall of fog forming in a circle around her car and several others in the company parking lot - until she walked right into it. The weird feeling this produced shocked her back to reality, and she stopped, looking around, confused. She saw the fog, ringing a circle of cars and pavement, centered a few meters away, and watched, stunned, as it thickened. Then, as the feeling of strangeness increased, she panicked, yelling and jumping backwards. Only she didnt clear of the fog with her leap, landing short. Sarah began scrabbling, shoving against the pavement with her feet, frantically backpedaling. She flailed her arms... and froze, as she saw the skin on them darken. Sarah screamed and threw herself out of the fog with a final, desperate ...

It is harder to think about competition among eggs. To do this, we need need to take a step back and think not about competition between eggs, but about competition between the genetic content during egg formation. Competition in egg formation comes at the level of producing the egg, where you might have some alleles (variants of a gene) that distort inheritance so that instead of having a 50:50 chance of inheriting alleleA versus alleleB, the probability might be distorted to 90:10. This kind of distortion happens, but it doesnt happen all the time. Why ...

but other wise you have Janelle, not a good mother but still considered by the authorities to be better than Sarah, obviously, you had the nurse and you have Jolanda.. Jolanda was, actually a poor portrayal from a survivalist stand point. The oldest child was old enough to hide with the others and be ready to defend them if his parents were taken out. Jolanda should have flanked the three intruders when Enrique confronted them. That alone would have been a huge step. Or, you know, at least have her come out from hiding securing a long gun.. A few obviously female cops might have helped. It looked like there might have been a couple in the stand off outside Cyberdyne….but all recognizable cops were clearly male. There really were female cops in 1991. Hell, there were in 1984 but it was made clear that all the ones in the station in The Terminator were men with families, children. Given no real substantial female roles other than Sarah, I feel it fails the Bechdel Test although its been given ...

Posted on 04/03/2016 12:18:24 PM PDT by Brices Crossroads. As I watched Sarah Palin deliver a speech on behalf of Donald Trump the other day before an GOP establishment fundraiser in Wisconsin, I was struck by the enthusiastic response of the crowd. She received a standing ovation at the end. Ted Cruz, who followed her on the dais, received only light and intermittent applause. The contrast in their political skills was stark. Palin was the star who knew how to connect with, and hold, her audience. Cruz, not so much... Let me say at the outset that I am analyzing this from a purely utilitarian and political point of view. Anyone with a white hot, visceral dislike of Sarah Palin or anyone who has swallowed the MSM narrative that she is a stupid, inarticulate rube is not likely to be voting for Donald Trump anyway. Trump obviously holds Palin in high regard and says so quite often, calling her an amazing woman and a special person. If he did not consider her a genuine asset, why in the world ...

I had a FET cycle last month. We transferred three day-6 blasts. I had a very early positive HPT, and my betas were excellent. At 5w2d, we saw two gestational sacs, both of which measured right on target. Today, at 6w2d, both sacs had grown at the same pace. However, one was empty. The other sac showed a yolk sac and fetal pole, measuring correctly, with a strong heartbeat. Is this common with IVF? I know that its extremely unlikely that I will see a baby in the second sac next week at my follow-up sono, given that there is no room for error in the dates, but do I need to be concerned for my surviving baby? If the empty sac continues to grow, will too much fluid build up and put the baby at risk? Sorry if this sounds completely ignorant. I am afraid to turn to google for this one.
