The Broholmer, also called the Danish Mastiff, is a large Molosser breed of dog from Denmark, recognized by the Danish Kennel Club and the Fédération Cynologique Internationale.
 It has been employed as a guard dog in the homes of the wealthy.
 The breed's numbers dwindled severely during World War II, but the dog made a successful return in the 1970s.
The Welsh Springer Spaniel is a breed of dog and a member of the spaniel family.
 Thought to be comparable to the old Land Spaniel, they are similar to the English Springer Spaniel and historically have been referred to as both the Welsh Spaniel and the Welsh Cocker Spaniel.
 They were relatively unknown until a succession of victories in dog trials by the breed increased its popularity.
 Following recognition by The Kennel Club in 1902, the breed gained the modern name of Welsh Springer Spaniel.
 The breed's coat only comes in a single colour combination of white with red markings, usually in a piebald pattern.
 Loyal and affectionate, they can become very attached to family members and are wary of strangers.
 Health conditions are limited to those common among many breeds of dog, although they are affected more than average by hip dysplasia and some eye conditions.
 They are a working dog, bred for hunting, and while not as rare as some varieties of spaniel, they are rarer than the more widely known English Springer Spaniel with which they are sometimes confused.
The Russian Spaniel is a type of spaniel first standardised in 1951 in the Soviet Union after World War II by cross breeding English Cocker Spaniels, English Springer Spaniels and other spaniel breeds.
 Physically it is similar to a Cocker Spaniel, but has a shorter, tighter coat and a longer body.
 Developed and used as hunting dogs, this breed does not suffer from any major health complaints other than those normally associated with spaniels.
 Popular in its native Russia, the breed was only introduced overseas in the 1990s, and is not yet recognised by any major kennel clubs.
The Obtshak (Russian), Obštšak (Estonian spelling), or Ühiskassa (Estonian) or "Common treasury" is a traditional umbrella organisation of criminal groups in Estonia, a trade union of sorts which settles conflicts and establishes the boundaries of the spheres of interest of the various groups such as the Estonian mafia and Russian mafia.
 Between 2003–2016, the Common Fund was dominated by Nikolai Tarankov of Ukrainian or Belarusian heritage and KGB training.
 However, Tarankov was found murdered in 2016, apparently in a revenge murder related to his past actions.
 The Common Fund pays for lawyers of caught members, purchases and delivers packages to imprisoned members and covers other expenses.
 The organization has about ten member groups.
 The members have also operated significantly in Finland, where in 2009 high-level drug dealing was controlled by Estonians.
The Russian Orthodox Church of Saint Elizabeth in Wiesbaden (German: "Russisch-Orthodoxe Kirche der heiligen Elisabeth in Wiesbaden" ; common local name "Griechische Kapelle", "Greek chapel"; Russian: Русский православный храм Св.
 Праведной Елиcаветы в Висбадене ) is the only Russian Orthodox church in Wiesbaden, Germany and is located on Neroberg.
 Besides the Russian church there is a parsonage and a Russian cemetery, which is the largest in Europe (outside Russia itself).
 St. Elizabeth's Church and its parishioners belong to the Diocese of Germany in the Russian Orthodox Church Outside Russia.
The Sussex Spaniel is a breed of dog developed in Sussex in southern England.
 It is a low, compact spaniel and is similar in appearance to the Clumber Spaniel.
 They can be slow-paced, but can have a clownish and energetic temperament.
 They suffer from health conditions common to spaniels and some large dogs, as well as a specific range of heart conditions and spinal disc herniation.
A perianal gland tumor is a type of tumor found near the anus in dogs that arises from specialized glandular tissue found in the perineum.
 Perianal glands do not exist in cats.
 It is also known as a hepatoid tumor because of the similarity in cell shape to hepatocytes (liver cells).
 It is most commonly seen in intact (not neutered) dogs and is the third most common tumor type in intact male dogs.
 There are two types of perianal gland tumors, perianal gland adenomas, which are benign, and perianal gland adenocarcinomas, which are malignant.
 Both have receptors for testosterone.
 Perianal gland adenomas are three times more likely to be found in intact male dogs than females, and perianal gland adenocarcinomas are ten times more common in male dogs than females.
 The most commonly affected breeds for adenomas are the Siberian Husky, Cocker Spaniel, Pekingese, and Samoyed; for adenocarcinomas the most commonly affected breeds are the Siberian Husky, Bulldog, and Alaskan Malamute.
In Russian, most surnames change depending on the gender of the person.
 The last names in the list below are all in the male form.
 The feminine form is the same plus an "a" at the end for most surnames ending in "v" and "n".
 Surnames ending in "y" change to the feminine form by replacing the ending with "-aya".
 A large number of Russian surnames also end in "evich," "ovich," or just "ich".
 Kuzmich and Verenich are common Russian surnames.
 Surnames ending in "evich" are common.
 For example, there is Stasevich, Fyodorovych, Ogiyevich, Alkhimovich, and Denisovich.
 It is believed that the "ich" ending last names originated from northern Belarus and southwestern Russia.
 Also, the "coch" ending last names are found everywhere in Kyrgyzstan, Kazakhstan, Ukraine, but most typically in Belarus and Russia.
The Orthodox, Byzantine or Russian (Orthodox) cross, also known as the Suppedaneum cross, is a variation of the Christian cross, could be found in every Eastern Orthodox Church, as well as the Eastern Catholic Churches of the Byzantine Rite, and used widely by groups to connote the Byzantine Rite.
 The cross has three horizontal crossbeams—the top one represents the plate which in the older Greek tradition is inscribed with a phrase based on John's Gospel "The King of Glory", but in later images it represents , and the bottom one, a footrest.
 In many depictions, the side to Christ's right is higher.
 This is because the footrest slants upward toward the penitent thief St. Dismas, who was (according to tradition) crucified on Jesus' right, and downward toward impenitent thief Gestas.
 It is also a common perception that the foot-rest points up, toward Heaven, on Christ’s right hand-side, and downward, to Hades, on Christ’s left.
 One of the Orthodox Church’s Friday prayers clearly explains the meaning: "In the midst, between two thieves, was Your Cross found as the balance-beam of righteousness; For while one was led down to hell by the burden of his blaspheming, the other was lightened of his sins unto the knowledge of things divine, O Christ God glory to You."
 Though commonly associated with the Russian Orthodox Church, this version is found also in the Greek and Serbian Orthodox churches, although other varieties are also common, including those with a straight footstool and one slanted in the opposite direction.
 Common variations include the "Cross over Crescent" and the "Calvary cross".
 The Byzantine cross is also the name for a Latin cross with outwardly spreading ends.
 It was the most common cruciform in the Byzantine Empire.
 Other crosses (patriarchal cross, Russian Orthodox cross, etc.) are sometimes misunderstood as "Byzantine cross" when they are from the Byzantine culture.
Chiari-like malformation (CM) is the most common cause of foramen magnum obstruction and syringomyelia in dogs.
 Syringomyelia (SM) is a disease of the spinal cord typified by fluid filled cavities, or syrinxes, within the spinal cord substance.
 The disease is caused by the obstruction of cerebrospinal fluid (CSF), in the nervous system.
 A situation of high pressure in the spinal cord compared to low pressure outside, leads to fluid accumulation, which eventually forms cavities.
 CM is a condition characterized by the mismatch of size between the brain and the skull.
 The skull is too small causing part of the brain to descend out of the skull through the opening at its base, crowding the spinal cord.
 The cause of CM is not yet fully understood.
 CM is rare in most breeds but reportedly has become very widespread in the Cavalier King Charles Spaniel and the Griffon Bruxellois (Brussels Griffon).
 Some researchers estimate that as many as 95% of CKCSs may have CM.
 It is worldwide in scope and not limited to any country, breeding line, or kennel, and experts report that it is believed to be inherited in the Cavalier King Charles Spaniel.
 CM is so widespread in the Cavalier that it may be an inherent part of the CKCS's breed standard.
 This disease not only affects thousands of dogs, but a similar condition affects over three hundred thousand children yearly.
 Therefore, canines are an appropriate model for the treatment of the human condition.
