Dogs were the first domesticated animal and, according to the archaeological evidence, have had a close relationship with humans for at least 15,000 years. Today, dogs are common pets in our society and have been linked to increased well-being and improved health outcomes in their owners. A dog in the family during childhood is associated with ownership in adult life. The underlying factors behind this association could be related to experiences or to genetic influences. We aimed to investigate the heritability of dog ownership in a large twin sample including all twins in the Swedish Twin Registry born between 1926 and 1996 and alive in 2006. Information about dog ownership was available from 2001 to 2016 from national dog registers. The final data set included 85,542 twins from 50,507 twin pairs with known zygosity, where information on both twins were available in 35,035 pairs. Structural equation modeling was performed to estimate additive genetic effects (the heritability), common/shared

Identical twins possess exactly the same set of genes. Yet as they grow older, they may begin to display subtle differences.. They may start to look different, develop different diseases or slide into different personalities. Women who are identical twins may differ in their fertility or in the age at which they reach menopause.. These discrepancies are usually attributed to ill-defined differences in environment.. But a whole new level of explanation has been opened up by a genetic survey showing that identical twins, as they grow older, differ increasingly in what is known as their epigenome. The term refers to natural chemical modifications that occur in a persons genome shortly after conception and that act on a gene like a gas pedal or a brake, marking it for higher or lower activity.. Identical twins have the same set of epigenetic marks on the genome when they are born. But differences in the epigenome emerge as the twins grow older and become greater the longer they live apart, say a ...

So, the doctor said she has never had to deliver twins with a combination of vaginal & c-section. This was music to my ears, because the recovery for that sounds pretty intense. She said if there is no medical necessity/emergency and twin A is vertex (head down), she usually tries a vag delivery. Then twin B usually is floating around in a strange position, so usually a little manipualation is needed (as in the practioner grabs the feet), and twin B is usually delivered breech. This is safe since the cervix has already dilated and delivered one baby. I asked if both babies are ever delivered vertex.. and she said it does happen if twin B rotates into that position after the first birth, but its much more common for the second to be breech. So it sounds like I will only get a C-section if I really need it.. which is good.. but the whole manipulating the baby while hes still inside scares me a little! She said all the doctors in the practice have the same philosophy too, just in case I am ...

But as it turns out, simply sharing clothes and finishing each others sentences is definitely not the extent of a close twin relationship. In fact, 31-year-old identical twins Anna and Lucy DeCinque from Perth in Western Australia, wont stop until their lives are entirely identical.. Watch as the pair discuss their unconventional lifestyle:. The twins made quite an impact on the web a few years back when they shared with the world the unusual fact that they have the same boyfriend, electrical mechanic Ben Byrne.. And perhaps even more bizarre is the fact that they have spent a whopping $240,800 on cosmetic procedures to look even more identical. Theyve had breast implants, lip fillers and their eyebrows and eyelashes done all in the name of looking exactly the same.. ...

Brigette and Paula Powers were 32-year-old identical twins in Australia when this video was recorded. They are closer than the average set of twins, and probably always will be. They are so used to talking at the same time that it doesn’t seem like they ever talk to each other, but then again, they probably don’t need to, since each already knows everything her sister knows.[https://youtu.be/MtEdP267TZ0] (YouTube link)Anyone who isn’t a twin would be hard put to understand what’s ...

OBJECTIVE: To compare dietary habits between Finnish twin migrants to Sweden and their co-twins always living in Finland, and to analyse how migration influenced food consumption patterns in the migrants. SUBJECTS/METHODS: Same-sexed twin pairs born in Finland below 75 years of age, with at least one twin migrating to Sweden (n=1083 pairs). Dietary habits were assessed by a food frequency questionnaire included in a comprehensive mailed questionnaire (response rate 71%). For 76 male twin pairs, information was also collected by a dietary history interview inquiring the habitual diet during the previous year. RESULTS: Migrant twins in Sweden had a lower intake of typical Finnish foods like dark bread and berries, and an increased consumption of fresh fruit compared with co-twins living in Finland. The migrants consumed less potatoes and more rice and pasta. Sweet pastries were consumed less often by the migrants and they also tended to more often cut out visible fat of meat and on the other hand ...

In most existing surveys the follow up period is too short or the sample size insufficient to draw firm conclusions.20 21 Only one recent Swedish register study on children born from 1982 to 1995 that examined neurological sequelae in children born after assisted conception had a sufficiently large sample size (2060 IVF twins). In this study, IVF twins were compared with a matched group of non-IVF twins, and IVF singletons were compared with a matched group of non-IVF singletons.7 The researchers found that IVF twins had a similar risk of neurological sequelae as their naturally conceived peers, but, in contrast to our results, they showed that the risk of neurological sequelae was higher in IVF twins than in IVF singletons. They did not, however, study the effect of ICSI. The crude prevalence of cerebral palsy per 1000 children in the Swedish study was 7.4, 6.9, and 3.8 for IVF/ICSI twins, control twins and IVF or ICSI singletons, respectively. In our study the corresponding rates were 3.2/1000 ...

Mom beats overwhelming odds to deliver 2 sets of identical twins The 36-year-old Houston native naturally gave birth at The Womans Hospital of Texas to a rare form of quadruplets: two sets of identical twins - a statistical phenomenon. The arrival of Ace and Blaine then Cash and Dylan a minute later was even more unusual because the Montalvos did not take fertility drugs or use in-vitro fertilization, which have contributed to a 76 percent increase in multiple births nationwide between 1980 and 2009, according to the Centers for Disease Control and Prevention. According to previous reports, Dr. James Grifo, director of the NYU Fertility Center, has said the odds of having two sets of identical twins at the same time are 1 in 10,000 with in-vitro and much rarer with natural conception. On Monday, Manuel, 43, pushed his wifes wheelchair into the neonatal intensive care unit at the Houston hospital, their 2-year-old son Memphis holding Mickey Mouse as he sat on his mothers lap. With no serious

The relationship between twins is both a bond and a rivalry that begins in the womb and lasts until they die. For the one in three sets of twins who are identical, the closeness can lead to uncanny skills at communicating with each other. During infancy and toddlerhood, they may even develop their own language. To the parents who raise them, twins bring a special set of frustrations, challenges and rewards. And one of the frustrations is that the ways parents have been advised to raise twins have shifted dramatically in recent decades. ``Until the 1970s, parents and professionals were comfortable treating twins as a single unit instead of as individuals,`` says Dr. Judith Landau- Stanton, an associate professor of psychiatry and family medicine at the University of Rochester, and the mother of 20-year-old identical twins.

ST. PAUL - State Representative Patrick Garofalo, R-Farmington, announced today his plan to introduce legislation that would free the Minnesota Twins to play home games in Wisconsin until Governor Walz gives the Twins organization the chance to have fans at Target Field. The Milwaukee Brewers were recently granted permission from local health officials to host games with over 10,000 fans.. Teams across the country have safely allowed fans at stadiums and even typically liberal states like Colorado have announced that fans will be able to enjoy outdoor baseball, said Rep. Garofalo. Releasing the Twins from any state contractual obligations to play in Minnesota, will give Minnesotans the chance to cross the river and cheer on the team. The Twins are not the only business having to tolerate the slow moving Walz administration. This is illustrative of what the wedding planning, youth sports tournament and hospitality industries have been dealing with. Minnesotans are ready to safely reopen many ...

Determining if same-sex twins are identical or non-identical (from one egg or two; monozygotic or dizygotic) is not always straight forward, say the researchers. They looked at data from the Gemini study, a birth cohort of 2402 families with twins born in England and Wales in 2007.. Parents of same sex twins (1586) were asked if they knew whether their twins were identical or not and how they discovered that information.. The majority of parents (1302/82%) reported that they had been given the information by health professionals based on the formation of the placenta as seen on the prenatal scan. Of this group, as part of the Gemini data collection, all parents completed a validated zygosity questionnaire[i] when their twins were on average 8.2 months old. This questionnaire asks about the childrens height, eye colour, hair colour and overall confusability and has been found in a previous study to correctly assign zygosity in 95% of cases.. The researchers found that out of the 1302 parents, ...

In fact with about 35-45 twins per live birth, this village in North Kerala, India, has four times more twins than normal. Not surprisingly, the village has been dubbed the twin village.. There seems to be a statistical error in this article. It says that in this one village there are 35-45 twins per live birth but that seems way out of line (how can you even have more than two twins per live birth). Perhaps its per 1,000 live births or something else?. J.T.D.. That makes it sound like for every live birth, 70-90 babies are popping out of a single women.. Keri.

Background Atopic traits often co-occur and this can potentially be caused by common aetiological relationships between traits, i.e. a common genetic or a common environmental background.. Objective To estimate to what extent the same genetic and environmental factors influence wheeze, rhinitis, airway hyper-responsiveness (AHR), and positive skin prick test (posSPT) in a sample of adult twins.. Methods Within a sampling frame of 21 162 twin subjects, 20-49 years of age, from the Danish Twin Registry, a total of 575 subjects (256 intact pairs and 63 single twins), who either themselves and/or their co-twins reported a history of asthma at a nationwide questionnaire survey, were clinically examined. Symptoms of wheeze and rhinitis were obtained by interview; airway responsiveness and skin test reactivity were measured using standard techniques. Correlations in liability between the different traits were estimated and latent factor models of genetic and environmental effects were fitted to the ...

Sharing of intrauterine environment in twins of opposite sex has been hypothesized to result in masculinization of the female twin. We tested this hypothesis by comparing strength (maximum hand-grip pressure) and various anthropometric measures in a newly established survey panel comprising 4,314 middle-aged twins identified through a Danish population-based twin registry. Sex- and zygosity-specific mean values of handgrip strength, height, weight, body mass index, and waist circumference were highly comparable between fraternal twins of opposite sex and fraternal twins of same sex. Our results provide no support for the hypothesis of masculinization of female twins from opposite sex twin pairs. (© 2001, LIPPINCOTT WILLIAMS & WILKINS ...

There have also been many twin studies of ADHD from Europe, the United States and Australia. There are two types of twins. Identical twins are genetic copies of one another. They share 100 percent of their genes. Fraternal twins are like regular brothers and sisters. They only share 50 percent of their genes.. All of the twin studies show that if one twin has ADHD, the probability that the other twin has ADHD is much greater if the twins are identical. This is very strong evidence that genes are involved in causing ADHD.. Very recently, I worked with an international group of over 100 scientists and clinicians to study the genetic material (DNA) of 20,183 people diagnosed with ADHD and 35,191 not diagnosed with ADHD. When we compared these two groups, we found convincing evidence that 12 areas of the human genome harbored risk genes for ADHD. These data also proved that there were many more risk genes to discover. The total number is unknown but it could be in the thousands. The data also showed ...

I think it is also worth saying that the obesity-destined twin was noted, by all and sundry, to be overeating, eating badly and eating irregularly from an early age, with a preference for fatty foods. However I would comment that they did not even begin to become obese until 18 years of age and by 25 years of age doubly labelled water showed... etc etc etc. This moral failing as youngsters might just be translated as the pre-obese half of the pair were HUNGRY at that time. Life is hard when the world views your moral failings at the snack bar as evidence of your lack of will power. Being hungry is no fun. Being hungry because your adipocytes are not fat enough (yet) to ignore your hyperinsulinaemia and let you, grudgingly, have a few FFA molecules from their hoard is somewhat unfair. Your skinny twin is not hungry. He has mitochondrial ATP to spare. He sniggers at your third helping of pizza at your 18th birthday party because he has no gnawing hunger. He knows that you lie about how much you ...

In the comments below, John Howard asks in relation to me releasing my genotype into the public domain: Im curious if this means you give permission to be cloned, or for someone to reproduce with you, by making gametes from your genome. Do you think other people have the right to do that? Ill be honest that I laughed when I first saw this comment. My genome is not magical. If someone wants to make more of me (and I can see why theyd want to do that), I probably wouldnt mind. My siblings are versions of me diluted by a factor of 1/2, if you want to think in terms of blending analogies. But the biggest issue is this: identical twins already share very concordant genomes, and no one would presume that one twin should have a right to a say in the use of the genome of the other twin. Then again, John Howard runs a website EggsAndSperm.org, Dedicated to stopping genetic engineering of human beings, and preserving individual conception rights for all people. All people should be created equal, ...

To conclude, I would be interested in hearing what you have to say to my conjoined twins scenario. A single embryo at some point splits, but not completely enough to have it become a separate organism (or at least, not permanently). It then develops into identical twins who are (say) conjoined at the hips (they share the same pair of legs). If our only moral ingredients are biological, then this is only one human being. From my perspective however, since personhood depends on relevant neural structure, I would say we have two human beings (in the moral sense--one in the biological sense) since there are two brains. So as I understand your perspective, destroying said twins before birth and cell splitting would be one murder, and destroying said twins after birth would be two murders (but why two if your only criterion is biologically human genetic code ...

Carl Pavano will turn 37 in January, and he knows that, eventually, his body will betray him. It happens to every athlete. But the Twins right-hander said Friday, Sept. 7, hes confident that hasnt happened yet and that he will pitch in 2013.. Whether its with the Twins, who acquired him in a lopsided waiver-wire deal in August 2009, is a question for another time. I dont want to go out this way, I know that, he said. Pavano is out for the season because of a bruise in the part of his humerus bone that attaches to the shoulder joint. The injury was diagnosed by specialist Dr. David Altchek on Aug. 21, ending a long, thankless rehab assignment at the Twins facility in Fort Myers, Fla., where Pavano was trying to pitch through discomfort and weakness in the shoulder initially diagnosed as inflammation in the anterior shoulder capsule. He returned to the Twin Cities this week to spend time with the team he helped to win a Central Division title in 2010, when he led the staff with a 17-11 ...

Conjoined twins were born with one of them having no proper heart or lungs. One of the twins was being kept alive by the other twin whose heart circulated blood for both of them. The Doctors wanted to operate to separate the twins. This would result in the weaker twin dying. The parents would not consent to this. The Doctors claimed that it was lawful to operate. The Court of Appeal gave the declaration. In the judgement, one of the points considered was the doctrine of necessity. ...

Journal: Brain Pathology. Twins who died after suffering from dementia and Alzheimers disease had similar areas of damage to their brains, a project by researchers in California and Sweden concluded.. The scientists studied the brains of seven pairs of twins who died after years of diagnostic tests - among them the brains of identical twins who died at age 98 after being diagnosed with Alzheimers. The results support previous findings that genetics may determine how vulnerable someone is to Alzheimers and other conditions, said University of Southern California psychologist Margaret Gatz, who led the study.. We looked not just at the hallmark indicators of Alzheimers, but at all the other damage in the brain. Across the whole array of neuropathological changes, the identical twins appeared to have more similar pathologies, Gatz said in announcing the findings. This is fascinating. Its not just a key pathology related to the twins diagnoses but the combination of things happening in ...

Twins Family friends are expecting twins. While they are, of course, excited, they also are looking for advice on parenting two new daughters. As a parent of twins, they asked me some any words of wisdom. As I wrote my recommendations in a letter to the mom and dad, I thought that this advice may be relevant to other parents or grandparents of twins. Also, it can certainly be modified to use with children that are not born five minutes apart. Here it is:Dear Friends,I am glad you are looking forward to the adventure of twins. I wish I could give you advice that would help for every scenario you might face. Unfortunately, there will be times when you have to, as my Grandmother used to say, Just fly by the seat of your pants . However, I do have some routines that worked well for my family.When you go to pick up a baby, do not go to the same crib first each time.

Identical twins are determined to be genetically the same and often only differ by 5.2 genetic changes. They come from a single fertilized egg and can also be referred to as monozygotic twins. Recently, a new finding suggests that identical twins may not be carbon copies after all. In Iceland, researchers conducted a study looking at the complete genetic makeup of 381 pairs of identical twins. Only 38 of those pairs were duplicates of each other and had the exact same genetic makeup. Most of the DNA pairs consisted of a couple differences that the researchers suspected arose either before one embryo split or very early in development. Shockingly of the 381 pairs, 39 of them had more then 100 changes between the twins. Ones theory that resulted from the study was that more uneven splits of the embryo can lead to a greater number of differences.. I was shocked to find out that identical twins may not be exact duplicates of each other. I was always taught that identical twins didnt have any ...

Since RNA viruses have been shown to cause leukemia in mice, rats, cats, and birds, intensive studies have attempted to link similar viruses with human leukemia. In the absence of a demonstrable human leukemia virus, immunological attempts to detect viral antigens have been hampered by lack of suitable controls. This study of identical twins, one with leukemia and one clinically normal, provided an excellent opportunity to use a variety of test procedures to detect an antigen in the leukemic patient, possibly tumor-specific, that would not be present in the identical twin. Four sets of identical twins, all children with acute ...

Monozygotic twins are genetically nearly identical and they are always the same sex unless there has been a mutation during development. The children of monozygotic twins test genetically as half-siblings (or full siblings, if a pair of monozygotic twins reproduces with another pair or with the same person), rather than first cousins. Identical twins do not have the same fingerprints however, because even within the confines of the womb, the fetuses touch different parts of their environment, giving rise to small variations in their corresponding prints and thus making them unique.[28]. Monozygotic twins always have the same phenotype. Normally due to an environmental factor or the deactivation of different X chromosomes in female monozygotic twins, and in some extremely rare cases, due to aneuploidy, twins may express different sexual phenotypes, normally from an XXY Klinefelter syndrome zygote splitting unevenly.[29][30][31]. Monozygotic twins, although genetically very similar, are not ...

Following widespread application of assisted reproductive technology modalities and the increased age of motherhood, the incidence of twin gestations has increased markedly. Twins are either monozygotic or dizygotic. Dizygotic (i.e. fraternal) twins result from the fertilization of two different eggs and are per definition dichorionic (DC). Chorionicity of monozygotic twins ... read more (i.e. identical twins) depends on timing of splitting of the fertilized egg. If splitting occurs within three days after fertilization, the monozygotic twin will be DC. Splitting after the third day results in monochorionic (MC) twinning. Twins have an increased risk of perinatal mortality and neonatal morbidity compared to singletons. MC twin pregnancies, which occur in about 1 of 400 pregnancies, carry a higher risk of perinatal complications compared to DC twins. This is mainly attributed to the unique architecture of the MC placenta. The aim of this thesis was to study perinatal mortality and (long-term) ...

The sometimes-preternatural similarity of identical twins is more profound than previously thought. Identical twins, known to science as monozygotic, may share more than identical looks and genes, according to new research in the field of epigenetics … ...

Although clones start off identical, they may not stay that way. Identical twins always have slightly different phenotypes.[2][3]. Although monozygotic twins are genetically almost identical, a 2012 study of 92 pairs of monozygotic twins found that monozygotic twins acquire several hundred genetic differences early in foetal development. This is caused by mutations (or copy errors) taking place in the DNA of each twin after the splitting of the embryo.[4] It is estimated that, on average, a set of monozygotic twins will have about 360 genetic differences that occurred early in foetal development. However, these changes may have little practical effect. In practice, identical twins look and act in a very similar way. Another cause of difference between monozygotic twins is epigenetic modification. These are caused by differing environmental influences throughout their lives, which affects which genes are switched on or off. A study of 80 pairs of monozygotic twins ranging in age from three to 74 ...

Identical twins always have slightly different phenotypes.[2][3] Although monozygotic twins are genetically almost identical, a 2012 study of 92 pairs of monozygotic twins found that monozygotic twins acquire several hundred genetic differences early in foetal development. This is caused by mutations (or copy errors) taking place in the DNA of each twin after the splitting of the embryo.[4] It is estimated that, on average, a set of monozygotic twins will have about 360 genetic differences that occurred early in foetal development. However, these changes may have little practical effect. In practice, identical twins look and act in a very similar way. Another cause of difference between monozygotic twins is epigenetic modification. These are caused by differing environmental influences throughout their lives, which affects which genes are switched on or off. A study of 80 pairs of monozygotic twins ranging in age from three to 74 ...

Results We conservatively characterised 23 de novo SNVs shared by the twin pair, 8 de novo SNVs specific to twin I and 1 de novo SNV specific to twin II. Based on the number of de novo SNVs validated by Sanger sequencing and the number of callable bases of each twin, we calculated the overall de novo SNV rate of 1.31×10−8 and 1.01×10−8 for twin I and twin II, respectively. Of these, rates of the early postzygotic de novo SNVs were estimated to be 0.34×10−8 for twin I and 0.04×10−8 for twin II.. ...

This study will evaluate the safety of giving lymphocytes (white blood cells) containing a new gene to HIV-infected individuals and will determine how long the cells survive in the bloodstream. Although the genetically altered cells will not directly benefit participants, knowledge about the safety, side effects and survival of these gene-marked cells in HIV-infected patients may lead to new treatment strategies.. Identical twin pairs 18 years of age and older-one infected with HIV, the other non-infected-may be eligible for this study. Candidates will be screened with a medical history, physical examination and blood tests.. All participants will have a tetanus booster shot. Non-infected twins will undergo a procedure called apheresis to collect white blood cells. For this procedure, whole blood is collected through a needle in an arm vein, similar to donating blood. The blood is separated it into its components by centrifugation (spinning), the white cells are removed, and the rest of the ...

Objective To determine the risk of perinatal death among twins born at term in relation to mode of delivery. Design Retrospective cohort study. Setting Scotland 1985-2001. Population All twin births at or after 36 weeks of gestation, excluding antepartum stillbirths and perinatal deaths due to congenital abnormality (n= 8073). Methods The outcome of first and second twins was compared using McNemars test and the outcome of twin pairs in relation to mode of delivery was compared using exact logistic regression. Main outcome measures Intrapartum stillbirth or neonatal death of either twin. Results Overall, there were six deaths of first twins and 30 deaths of second twins (OR for second twin 5.00, 95% CI 2.00-14.70). The odds ratio for death of the second twin due to intrapartum anoxia was 21 (95% CI 3.4-868.5). The associations were similar for twins delivered following induction of labour and for sex discordant twins. However, there was no association between birth order and the risk of death ...

The results of a twin zygosity test may be used to satisfy personal curiosity as well as to help solve future health problems. For example, in the event that a twin needs an organ or tissue transplant donor, the identical twin is a perfect choice. There are also cases in which medical records regarding zygosity have been lost, or doubt may have arisen because of the twins physical characteristics as they grow up.. In such cases only a DNA test will be able to reveal the truth. A twin zygosity test compares the twins DNA profiles to see whether they match. An exact match proves that the twins are identical.. ...

MINNEAPOLIS-ST. PAUL, Minn. - The Minnesota Twins Community Fund announced today the creation of Hope Week in 2011.

Also during the week, Joe and Lisa Nathan, along with the Minnesota Twins Wives Organization, will host their annual Hang with the Majors public event to raise funds for military families.. The week will culminate on Saturday, June 18 with an on-field event where deserving youth from Twins Territory will have a chance to meet the entire ...

MINNEAPOLIS-ST. PAUL, Minn. - Target Corporation (NYSE:TGT) and the Minnesota Twins, in conjunction with the Minnesota Ballpark Authority (MBA), today unveiled plans for the construction of Target Plaza - a pedestrian bridge and public gathering space connecting Target Field to the heart of downtown Minneapolis. The bridge spanning more than two acres between 6th and 7th Streets in the Minneapolis Warehouse District will become Target Plaza located on the east side of Target Field - the new world-class home of the Twins scheduled to open in 2010. The plaza will serve as the ballparks gateway from downtown Minneapolis. As announced in September of 2008, the Twins-Target partnership calls for both companies to contribute incremental funds to enhance the overall design of Target Plaza. In addition, the Twins are working with the MBA - the public owner of Target Field and Target Plaza - to ensure the extension of the plaza pedestrian bridge along 6th Street to 1st Avenue. The Minnesota Twins are ...

North Twin (Peak) is one of the two peaks that comprise The Twins massif located at the northeast corner of the Columbia Icefield in Jasper National Park, Alberta, Canada. The other lower peak is named South Twin (3,566 m). North Twin is the third-highest peak in the Canadian Rockies, after Mount Robson and Mount Columbia. The massif was named The Twins in 1898 by J. Norman Collie and Hugh M. Stutfield. The decision to name the peaks separately was approved February 28, 1980. In addition to North Twin and South Twin, the massif contains a northern subpeak of North Twin known as Twins Tower, 3,627 m (11,900 ft). This sits atop the famed north face of the massif (see below), and was named in 1984. The first ascent of North Twin was recorded on 10 July 1923 by W.S. Ladd, J.M. Thorington, and Conrad Kain, via the East Face. The normal route is a ski mountaineering climb on the eastern slopes, and it is possible to ski all the way to the summit. A traverse can be made to the South Twin, although an ...

TWIN studies have been broadly used as a tool to investigate heritability for decades. A recent comprehensive meta-analysis reported 17,804 heritability estimates for various traits based on twin studies (Polderman et al. 2015). Estimation methods and software such as structural equation modeling (SEM) based on the classical twin models consisting of additive genetic, common, and unshared environmental effects have been well established and extensively adopted (Rijsdijk and Sham 2002). Extensions for longitudinal data or time-to-event phenotypes based on the classical twin models have been proposed (Boomsma et al. 1989; Pitkäniemi et al. 2007). Nevertheless, one of the major issues posing potential challenge is that many twin data sets contain individuals across a wide range of age and the variances of genetic and environmental components for many complex traits such as body mass index (BMI) and height change over age (Lajunen et al. 2009; Elks et al. 2012) or birth cohorts (Silventoinen et al. ...

A pair of monozygotic twin girls with coeliac disease is reported. The diagnosis was made on clinical and biochemical evidence of malabsorption, characteristic histological findings, and clinical, biochemical, and histological response to gluten elimination. Monozygosity was established on finding a single placenta at birth, exact similarity of physical appearance, similar blood group, and histocompatibility antigens, and negative reaction in mixed lymphocyte culture. This is one of six well documented cases of coeliac disease in monozygotic twins and may throw light on the importance of genetic and environmental factors in the causation and expression of the disease.. ...

Umbilical vein thrombosis is a very rare cause of single fetal demise in twins. Case: Three days after a reassuring biophysical profile, a 40-year-old primigravida with twin pregnancy presented at 38 weeks gestation in early labor when demise of 1 of the twins was recognized. She underwent a cesarean section for arrest of labor, delivering twin A, a stillborn female weighing 2360 g and twin B, a liveborn male weighing 2200 g. Umbilical vein thrombus was noted in twin A. Conclusion: Umbilical vein thrombosis is a rare and sudden cause of fetal demise.. AB - Background: Single fetal demise in a twin ...

While for some it is the one child that parents want to revolve their lives around and put in their heart and soul bringing them up, there are others who desire the rarer twins, so that they have their hands full all the time and bring up two identical yet different but wonderful human beings. Though getting pregnant with twins is an event that is mostly attributed to luck, there are a few things that you may be able to do in order to actually conceive them. Whether they will be identical or fraternal cannot be assured. Here are some tips that will tell you how to get pregnant fast with twins. Take a look. Tips on Getting Pregnant with Twins. As mentioned earlier, to get pregnant with twins is nothing less of a miracle, but sometimes, knowingly or unknowingly, we are capable of making miracles happen. It is also a fact that people with a family history of twins are more likely to have twins for kids. As such, if you or your partner belong to such a family, your chances of having twins has just ...

Identical twins have to be the same sex because they both come from one egg. This means that they have identical genetic material, and therefore identical chromosomes.

Jenna and Jillian Thistlethwaite are identical twins developing opposite personalities. Despite their differences, the sisters from Ohio share a remarkable bond and an amazing story that continues to make people smile nearly seven years after their births.

Seven pairs of young adult male identical twins completed a negative energy balance protocol during which they exercised on cycle ergometers twice a day, 9 out of 10 days, over a period of 93 days while being kept on a constant daily energy and nutrient intake. The total energy deficit caused by exe …

An international group of researchers has discovered a new phenomenon that occurs in identical twins: independent of their identical genes, they share an additional level of molecular similarity that influences their biological characteristics. The researchers propose a mechanism to explain the extra level of similarity and show that it is associated with risk of cancer in adulthood. The results appear in the journal Genome Biology.

IDENTICAL twins Anna and Lucy DeCinque - with their identical boyfriend, bed, mobile phone number, clothes, hairstyles, diet and cosmetic enhancements, are accustomed to being the identical centre of attention.

Professor Plum did it -- in the study with the lead pipe. Or was it Professor Plums identical twin? A new method could distinguish their DNA.

Genes vs. Environment. Some of the most startling and convincing data on the relative influences of genes vs. environment come from studies of identical twins who were separated at birth and reared apart. Identical twins come from a single egg that splits in two; the twins are genetically identical. Fraternal twins are produced by a double ovulation and are no more genetically alike than ordinary siblings. (Unlike fraternal twinning rates, there are no racial differences in the frequencies of identical twinning.). The crucial finding is that identical twins reared apart are more like each other in virtually every way than are fraternal twins who were reared in the same household. From these similarities it is possible to estimate how much of the variation in personality traits is caused by genes and how much by environment.. The chart at the bottom of this page shows twin-study estimates of the genetic contribution to various attitudes. These estimates almost certainly undervalue heritability ...

Did you ever wish you had access to a searchable database of twin correlations and trait heritability statistics? If not, once you see this, you will wonder why you hadnt been looking for this kind of resource. Shout out to David Myers (Hope College) for pointing me toward MaTCH. Lets take height as an example. From the first drop-down menu, select ICF/ICD10 Subch and then from the second drop-down menu, select Height (297). The number in parentheses refers to the number of studies included in the displayed data. This is the first chart that is generated. If one identical (mz = monozygotic) twin is tall, there is a very good chance the other will be as well. If one is short, there is a very good chance the other will be as well. The correlation between being a twin and height is .91. The chart also gives correlations for just male identical twins (mzm = monozygotic male) and female identical twins (mzf = monozygotic female). If one fraternal (dz = dizygotic) twin is tall, there is a smaller ...

The abstract follows: IMPORTANCE Observational studies have shown that obesity is…

During 1980-1994, the number of twin births in the United States increased by 42%, from 68,339 to 97,064, and the twin birth rate (i.e., the number of twin births to total live births) increased 30%, from 18.9 to 24.6 per 1000 live births. These increases are important because the risks for preterm birth, low birthweight (LBW), long-term disability, and early death are greater for twins than for singletons (1; CDC, unpublished data, 1991). To estimate state-specific rates of twin births, CDC analyzed data from the U.S. certificates of birth for 1992-1994. This report presents the findings of this analysis of these data, which indicate that state-specific rates of twin births varied substantially, and the variations reflect factors other than state-specific differences in maternal age distributions. In this analysis, twin births were defined as individual live births in twin deliveries, rather than sets of twins (e.g., a delivery resulting in one live birth and one stillbirth is reported as one ...

A twin study like this one involves analyzing data on identical twins. (Twin pairs that are not identical, and therefore do not have identical DNA, provide much less information about genetic effects). The study can give a statistical figure for the percentage of risk for some condition (Alzheimers disease in this case) that is attributable to genetics. In this case, the risk is 79% (with 95% confidence). The implication is that in only about one fifth of identical twin pairs the disease will develop in one of the twins but not the other, presumably on account of some sort of environmental influence. In fact, in only about 45% of pairs where one twin has developed the disease has it appeared in the other also -- though it may well appear if the other twin lives long enough ...

Monochorionic twins are identical twins who share one placenta. Caring for pregnancies with monochorionic twins varies depending on the condition of the babies.

Because the defect in IL-4 secretion was likely the result of multiple differences, a representative clone pair was chosen for intensive analysis with DNA microarrays that monitor the expression of ≈6,800 genes (Unigene collection; National Center for Biotechnology Information, Bethesda, MD). The DNA microarrays provide a practical and reproducible approach for large-scale study of complex differences in gene expression (11-14). Expression profiles were determined after 4 h of stimulation with anti-CD3 or control IgG. This time point was selected because it was used in a previous analysis of cytokine secretion in clones derived from monozygotic twin pairs discordant for type 1 diabetes (8). The number of genes with detectable expression either before or after stimulation was nearly identical for the IL-4 null and IL-4-secreting clones (1,523 and 1,558, respectively). As expected, the frequency of the majority of transcripts was unchanged. Interestingly, only about 2/3 of this set (988) were ...

The idea that twins develop entirely fabricated secret languages that only they use and only they can understand has long been a source of fascination for scientists and lay people alike. This is known as twin language, idioglossia or cryptophasia. In most cases, however, what the twins are speaking is not an entirely new or separate language. Its actually a matter of delayed or poor speech development in either one twin or both. Heres a possible scenario: Twin A has difficulty articulating certain sounds and thereby certain words. Although twin B is better able to articulate these sounds and words, he chooses to mimic or repeat the manner in which Twin A speaks. So, the two continue to talk this way, understanding what the other is saying but meanwhile it sounds like gibberish or some concocted language to you.. Why does this happen? There are a number of theories. For one, delayed speech in general is related to low birth weight and premature births. Statistics indicate that nearly 60 ...

For many twins, particularly identical, they are commonly seen as perfect halves to a whole - two parts to a puzzle that is only complete when theyre together. Yet twins, like any two siblings, have their own minds and their own personalities in spite of the fact that they may look similar. As a matter of fact, its these same twins need to be seen as individuals that often compels them to behave so differently from one another. How often have we heard about twins where one is shy and the other outgoing? Or where one is a left-brain logical type and the other a more creative sort? And dont get me started on the good twin/bad twin dichotomy. It doesnt exist.. Regardless of the labels that are put on them, twins are often seen as a package deal and no attempt at differentiating themselves from each other is successful as a result. For a twin child, being seen and appreciated as an individual will not only increase their confidence and abilities as they move through the difficult teenage ...

Separated twins shed light on identity issues Though they share same DNA, the 2 women have vast differences Both women had the same delicate wrists and rounded hips, the same allergy to sulfa drugs. Identical twins offer a tantalizing window into the power of inheritance, and current twin studies continue to shake up our understanding of mental health, personality, the influence of parenting, and the meaning of identity. When I was a student, mothers were considered the cause of schizophrenia, said psychologist Thomas Bouchard, head of the Minnesota Center for Twin and Adoption Research. Schein thought that was all she would discover when, some months later, she received a certified letter from an adoption agency. Eventually a social worker connected to the adoption agency found her lost twin. The social worker explained to Schein that the pair had been separated as part of an experiment, but said that she did not know the details. Bouchard himself believes that twins reared apart could yield
