Introduction: Sacral agenesis (SA) is a caudal regression anomaly that can cause neurogenic bladder but is not generally recognized as high risk. We studied the clinical presentation, upper urinary tract, bone and spine abnormalities, and urodynamic findings in patients with SA and compared them with related high-risk conditions, anorectal malformation (ARM), and cloacal malformation. Materials and Methods: Patient records between May 2011 and December 2015 were identified and grouped into isolated SA without an overt anomaly (Group I), SA with overt caudal regression anomalies (Group II), and ARM or cloacal malformation without the SA (Group III). Distribution of clinical and urodynamic findings and factors associated with reduced eGFR were tested with rank sum test, t-test, and unadjusted odds (P , 0.05 significant) using R statistical program (version 3.1.3). Results: Of 605 neurogenic bladder patients treated in the study period, 39 fulfilled the inclusion criteria. 12 were Group I, 5 Group ...
Definition: Anorectal malformations are a group of malformations that involve the distal anus and rectum as well as the urinary and genital tracts. Defects range from mild anal anomalies to complex cloacal malformations. Most anorectal malformations result from abnormal development of the urorectal septum, resulting in incomplete separation of the cloaca into urogenital and anorectal portions. A-The following are low malformations of the anorectal region: 1-Anal Agenesis, with or without fistula-The anal canal may end blindly and there may be an ectopic opening (ectopic anus), or fistula, that commonly opens into the perineum. However, the fistula may open into the vulva in females or the urethra in males. Anal agenesis with fistula results from incomplete separation of the cloaca by the urorectal septum. It accounts for about 46 percent of cases. 2- Anal Stenosis--The anus is in the normal position, but there is a narrowing of the anal canal. This malformation is probably caused by a slight ...

The cause of fetal LUTO is varied. The most common cause in male fetuses is posterior urethral valves (membrane blocks the flow of urine from the bladder). Oligohydramnios (low amniotic fluid volume defined as the maximum vertical pocket less that or equal to 2.0 centimeters) may then develop, and is associated with a worse prognosis. In females the most common cause is urethral atresia (a body orifice or passage in the body is abnormally closed or absent). Other causes of fetal LUTO include but are not limited to obstructive ureterocele (area between the tube that carries urine from the kidneys to the bladder), urethral stricture (abnormal narrowing of the urethra) or agenesis (absence of), persistent cloaca (a defect in which the rectum, vagina, and urinary tract are fused together into a single common channel), and megalourethra (congenital dilation of the urethra). The ultrasound findings of many of these conditions are similar, and it is often difficult to differentiate the cause of the ...

Imperforate anus, a type of anorectal malformation, is caused by the failed rupture of the cloacal membrane during embryological development. The defect presents with failure to pass meconium within 24 hours, abdominal distension, and bilious vomiting. Imperforate anus should be detected on physical exam and can be complicated by fistulas between the rectum and urogenital system resulting in passage of meconium in urine in males and urinary tract infections. Imperforate anus is also associated with other congenital defects which are classified as VACTERL (vertebral, anal, cardiac, trachea-esophageal fistula, renal, and limb defects) abnormalities ...
23-26 (58-66 cm). Adult white with light gray back and wings; wing tip black with white spots; bill yellow with red spot on lower mandible; feet pink or flesh colored. First-year birds brownish. Acquires adult plumage in 4 years. See California Gull.
Gastrulation is continuing as cells migrate from the epiblast, continuing to form mesoderm. Mesoderm lies between the ectoderm and endoderm as a continuous sheet except at the buccopharyngeal and cloacal membranes. These membranes have ectoderm and endoderm only and will lie at the rostral (head) and caudal (tail) of the gastrointestinal tract. From the primitive node a tube extends under the ectoderm in the opposite direction to the primitive streak. This tube forms first the axial process then notochordal process, then finally the notochord. The notochord is a key to embryonic folding and regulation of ectoderm and mesoderm differentiation. It lies in the rostrocordal axis and the embryonic disc will fold either side ventrally, pinching off a portion of the yolk sac to form the lining of the gastrointestinal tract. ...

Summary Twelve influenza A viruses, antigenically related to the H0, H1 and Hsw1 subtypes, were isolated from cloacal samples of feral ducks in Canada. Antigenic comparisons showed that these viruses were most closely related to the recent Hsw1N1 isolates from man and pigs, whereas in vivo pathogenicity tests revealed differences between the Hsw1N1 viruses from the ducks and those from humans and pigs. Antigenic characterization of 94 additional influenza A viruses from the ducks showed four haemagglutinin subtypes (Hav1, Hav4, Hav5 and Hav7), an unclassified haemagglutinin, and six neuraminidase subtypes (N1, N2, Neq2, Nav1, Nav2 and Nav5) in various combinations, some of which are novel and have not previously been reported. Three of these duck influenza viruses possessed a haemagglutinin antigenically related to that of classical fowl plague virus. A much higher percentage of virus isolations were from juvenile ducks (18.5%) than from adults (5%). All of the ducks, from which viruses were isolated,
Sometimes factors can occasionally interfere with bladder development, as is the case for children with cloacal exstrophy. This is the most severe birth defect in the exstrophy-epispadias complex. A child with this condition will have the bladder and a portion of the intestines, exposed outside the abdomen, with the bony pelvis open like a book.

The hindgut follows the midgut, in the embryo, and extends from the posterior intestinal portal to the cloacal membrane. It gives rise to the left one-third to one-half or distal portion of the transverse colon, the descending colon, the sigmoid or pelvic colon, the rectum, the upper portion of the anal canal, and part of the urogenital system (e.g., the bladder and urethra). It is supplied by the inferior mesenteric artery. The terminal part of the hindgut enters into the cloaca, which is an entoderm-lined cavity that is in direct contact with the surface ...
The Northern Red-legged Frog is a medium-sized (7-10 cm) reddish-brown and black-speckled frog that gets its name from the translucent red undersides of its hind legs. Its range extends along the Pacific coast, west of the Coast and Cascade Mountains from southwestern British Columbia to northwestern California. In British Columbia, the Northern Red-legged Frog occurs mainly throughout the forested lowlands (| 1200 m elevation) of Vancouver Island, the adjacent Gulf Islands, along the mainland coast as far north as Kingcome Inlet, and in the Lower Fraser Valley to Hope. The Northern Red-legged Frog requires structurally complex wetlands (i.e., the ratio of emergent vegetation to open water) and forest habitats (i.e., abundant canopy cover, downed wood and litter) in a suitable spatial configuration to complete its life cycle.
Gulls are sociable and often found in groups at rest or when feeding.. Most gulls, particularly Larus species, are ground nesting carnivores, which will take live food or scavenge opportunistically. Live food often includes crabs and small fish. Gulls have prophylactic unhinging jaws which allow them to consume large prey. Apart from the kittiwakes, gulls are typically coastal or inland species, rarely venturing far out to sea.[citation needed] The large species take up to four years to attain full adult plumage, but two years is typical for small gulls. Large White-Headed Gulls are typically long-lived birds, with a maximum age of 49 years recorded for the Herring Gull.[2]. Gulls nest in large, densely packed noisy colonies. They lay two to three speckled eggs in nests composed of vegetation. The young are precocial, being born with dark mottled down, and mobile upon hatching.[3]. Gulls-the larger species in particular-are resourceful, inquisitive and intelligent[4] birds, demonstrating complex ...

Squalidus argentatus (Sauvage and Dabry de Thiersant 1874) is a small-sized freshwater fish which is distributed in Mainland China, Hainan Island and Taiwan. The populations of S. argentatus have dropped sharply probably due to overharvesting and water pollution recently. Eleven polymorphic microsatellite markers were developed for the cyprinid fish S. argentatus. These new markers were tested on 43 individuals collected from Yangtze River and Qiantang River. The number of alleles, observed and expected heterozygosity per locus, in two populations ranged from 3 to 14, from 0.333 to 0.954 and from 0.480 to 0.928, respectively. Only two loci are significantly deviated from Hardy-Weinberg expectations due to the heterozygote deficiency. No significant linkage disequilibrium was detected between the pairwise comparisons of these loci. These polymorphic microsatellite loci will enable us to study the genetic variation, population structure, and conservation genetics of this species in the future.
Phylogeographical analyses on Squalidus argentatus samples from thirteen localities within mainland China and Taiwan were conducted for biogeographic studies, as their dispersal strictly depends on geological evolution of the landmasses. A total of 95 haplotypes were genotyped for mtDNA cyt b gene in 160 specimens from nine river systems. Relatively high levels of haplotype diversity (h = 0.984) and low levels of nucleotide diversity (π = 0.020) were detected in S. argentatus. Two major phylogenetic haplotype groups, A and B, were revealed via phylogenetic analysis. The degree of intergroup divergence (3.96%) indicates that these groups diverged about 4.55 myr (million years) ago. Haplotype network and population analyses indicated significant genetic structure (FST = 0.775), largely concordant with the geographical location of the populations. According to SAMOVA analysis, we divided these populations into four units: Yangtze-Pearl, Qiantang-Minjiang, Jiulong-Beijiang and Taiwan groups. Mismatch

Rhodnius prolixus are ectoparasitic solenophages that feed primarily on the blood of mammals and birds. Rhodnius prolixus have sucking mouthparts which fold back beneath the head and thorax when at rest. The mouthparts consist of long stylets that include a short labrum with a long tubular labium that contains the mandibles and the maxillae. The maxillae enclose a food canal for sucking fluid, and a salivary canal that injects saliva to help digest host tissue.. The saliva contains some anticoagulants, and the painless bites of R. prolixus are usually around the eyes and mouth of the host, where they can suck blood for several minutes. Endosymbiotic bacteria help to digest the blood ingested by R. prolixus. The bacteria are contained in epithelial cells of the triatomine gut and are found among many of its tissues throughout its growth and maturation.. Dogs, cats, and rats are important Rhodnius prolixus hosts in urban environments. Some other less common hosts include opossum, armadillos, bats, ...

The Common Gull (European and Asian subspecies; see below) or Mew Gull (North American subspecies) Larus canus is a medium-sized gull which breeds in northern Asia, northern Europe and northwestern North America. It migrates further south in winter.[2] Its name does not indicate that it is an abundant species, but that during the winter it feeds on common land, short pasture used for grazing.[3]. Adults are 40-46 cm long, obviously smaller than the Herring Gull, and slightly smaller than the Ring-billed Gull, also differing from this in its shorter, more tapered bill with a more greenish shade of yellow, as well as being unmarked during the breeding season. The body is grey above and white below. The legs are greenish-yellow. In winter, the head is streaked grey, and the bill often has a poorly-defined blackish band near the tip (sometimes sufficiently obvious to cause confusion with Ring-billed Gull). They have black wingtips with large white mirrors. Young birds have scaly black-brown ...

The embryology of the human digestive system and the body cavities concerns the epithelium of the digestive system and the parenchyma of its derivatives, which originate from the endoderm. Connective tissue, muscular components, and peritoneal components originate in the mesoderm. Different regions of the gut tube such as the esophagus, stomach, duodenum, etc. are specified by a retinoic acid gradient that causes transcription factors unique to each region to be expressed. Differentiation of the gut and its derivatives depends upon reciprocal interactions between the gut endoderm and its surrounding mesoderm. Hox genes in the mesoderm are induced by a Hedgehog signaling pathway secreted by gut endoderm and regulate the craniocaudal organization of the gut and its derivatives. The gut system extends from the oropharyngeal membrane to the cloacal membrane and is divided into the foregut, midgut, and hindgut. At the end of the third week, the neural tube, which is a fold of one of the layers of the ...

Introduction: Increasing the usage of hearts from marginal donors and from donors after circulatory death (DCD) has the potential to expand the donor pool. Such hearts may be resuscitated when subjected to ex vivo perfusion. In addition, this may provide an opportunity for viability testing prior to transplant. We describe a novel ex vivo perfusion system designed to reanimate porcine DCD hearts. The same system was subsequently tested using a human heart from a marginal brainstem-dead donor.. Method: In the first phase of the study 23 porcine hearts were procured following circulatory death. All hearts were subjected to a period of primary warm ischemia followed by 120 minutes of hypothermic preservation. The period of hypothermic preservation was initially static cold storage (SCS); then oxygenated machine perfusion and finally a combination of static cold storage and oxygen persufflation via the coronary sinus. Ex vivo perfusion of the hearts was performed with a normothermic, oxygenated ...
Microphallus piriformes is a parasitic trematode (fluke). It belongs to the Plagiorchiata, a large suborder of the digenean fluke order Plagiorchiida. M. piriformes is unusual among the flukes in having only one intermediate host rather than two, and no free-swimming cercarian stage. It is most notable, however, for modifying the behaviour of its intermediate host in a way that increases its chance of transmission to the primary host. This has been researched by Helen O. McCarthy and her team of University of Ulster scientists both in the laboratory and at Muck Island in Scotland. The life cycle of M. piriformes requires two hosts: the rough periwinkle Littorina saxatilis (a littoral snail) and the herring gull Larus argentatus (and perhaps other members of the herring gull complex). The immature flukes live in the snail, and the adult flukes live in the bird. Normally, rough periwinkles are rarely eaten by herring gulls. This is due to two reasons: First, the birds forage in the snails rocky ...
Strontium is named after the village of "Strontian" in Scotland. Adair Crawford in 1790 recognized a new mineral (strontianite) in samples of witherite (a mineral consisting of barium carbonate, BaCO3) from Scotland. It was some time before it was recognized that strontianite contained a new element. Strontianite is now known to consists of strontium carbonate, SrCO3. The element itself was not isolated for a number of years after this when strontium metal was isolated by Davy by electrolysis of a mixture containing strontium chloride and mercuric oxide in 1808. Today, strontium is obtained from two of its most common ores, celestite (SrSO4) and strontianite (SrCO3), by treating them with hydrochloric acid, forming strontium chloride. The strontium chloride, usually mixed with potassium chloride (KCl), is then melted and electrolyzed, forming strontium and chlorine gas (Cl2). Strontium is a bright silvery metal that is softer than calcium and even more reactive in water; strontium will decompose ...
Egg composition varies both within and between clutches, and mothers are expected to alter their deposition of resources to the egg depending on environmental conditions and breeding strategies. Within-clutch variation in egg composition has been proposed to reflect an adaptive maternal strategy influencing sibling competition. In species with brood reduction, mothers should reinforce brood hierarchies due to hatching asynchrony and favour senior chicks by making first-laid eggs larger, richer in nutrients, with higher testosterone and carotenoid levels and lower corticosterone concentrations than last-laid eggs [parental favouritism hypothesis (PFH)]. Moreover, mothers that are of better quality and/or experience better feeding conditions during laying are expected to increase their deposition of resources to the egg, resulting in differences between clutches [investment hypothesis (IH)]. Several components may act together to provide an optimal reproductive strategy, but studies of variation ...

Abstract Objective: To determine the cause and mode of transmission of a cluster of infections due to Enterobacter cloacae. Design and Setting: Retrospective cohort study in a neonatal intensive-care unit (NICU) from December 1996 to January 1997; environmental and laboratory investigations. Subjects: 60 infants hospitalized in the NICU during the outbreak period. Main Outcome Measures: Odds ratios (OR) linking E cloacae colonization or infection and various exposures. All available E cloacae isolates were typed and characterized by contour-clamped homogenous electric-field electrophoresis to confirm possible cross-transmission. Results: Of eight case-patients, two had bacteremia; one, pneumonia; one, soft-tissue infection; and four, respiratory colonization. Infants weighing |2,000 g and born before week 33 of gestation were more likely to become cases (P|.001). Multivariate analysis indicated that the use of multidose vials was independently associated with E cloacae carriage (OR, 16.3; 95% confidence

The present study describes the development of a SYBR Green based real-time polymerase chain reaction (real-time PCR) for detection and quantitation of all fowl adenovirus (FAdV) species. Primers were designed based on conserved nucleotide sequences within the 52K gene. Ten-fold serial dilutions of a vector DNA were used as standard for quantitation. The real-time PCR had an efficiency of 98%, a regression squared value of 0.999 and showed a range of 6.73-6.73×10(8) copies of FAdV DNA per reaction. The assay was highly specific for FAdVs and an exact quantitation of all 5 FAdV species (FAdV-A to FAdV-E) could be demonstrated. It was shown, that twelve FAdV serotypes (FAdV-1 to 8a, and 8b to 11) were detectable and quantifiable. Other viral genomes as well as uninfected chicken embryo liver (CEL) cells did not produce positive signal. Cloacal swabs were taken during the animal experiment, which was performed with all FAdV species. Shedding of FAdVs was investigated in cell culture, by ...
